DETAILED DESCRIPTION
[0158] FIG. 1a and FIG. 1b show schematic cross sections of the components of an example component part 1 before the laying of the label 2 and the faceplate 3 one on top of the other with reference to schematic cross sections through the label 3, the adhesive 4 and through the carrier 3. FIG. 1c shows, schematically, a cross section through an example component part 1 with the label 2, the adhesive layer 41 and the carrier 3. As is illustrated by way of example by FIGS. 1a to 1c, it is possible for the glue to be displaced from the one or more first defined shapes, for example the shape shown in FIG. 1a or FIG. 1b, to one or more second defined shapes, such as the shape of the adhesive layer 41, by the laying of the label 2 and the carrier 3 one on top of the other, with the result that the one or more adhesive layers, in particular the adhesive layer 41, results therefrom. Through the flowing of the adhesive 4 during this process, in particular, elevations and indentations, preferably with small radii of curvature, can be filled with adhesive 4 and/or nuisance particles can be enclosed, preferably without bubble formation. This is illustrated by way of example in FIG. 4b and described in more detail in relation thereto. It is advantageously possible to carry out an automated method and/or to use a device for carrying out the automated method. In particular, at least the laying of the label 2 and the carrier 3 one on top of the other can be carried out in an automated manner or is carried out in an automated manner.
[0159] FIGS. 2a to 2c show example component parts 1. As is shown there, it is possible for the carrier 3 to have a complex geometry. The carrier 3 has for example a cylindrical curvature, in particular a so-called 2.5D shape. In particular, it is possible for the carrier 3 additionally to have a frame. It is thus possible in particular for the carrier 3 to have a 3D shape with a 2.5D surface area to be coated with the label 2. However, it is also conceivable that the carrier 3 has been designed smooth and flat, for example in the form of a glass substrate. It is possible for the carrier 3 to have been or to be produced by plastic injection molding. In addition, it is possible for the carrier 3 to be transparent, opaque, partially transparent and/or non-transparent in areas or over the whole surface. In particular, the carrier 3 can have one or more transparent windows, for example for a display, and/or one or more patterned transparent areas, for example symbol-shaped areas, in particular for buttons. It is therefore advantageous if the adhesive and/or the one or more adhesive layers expediently do not influence the transparency.
[0160] The carrier 3 preferably has a maximum wall thickness in a range of from 0.15 mm to 10 mm, in particular from 1 mm to 5 mm. It is possible for the carrier 3 to have such a maximum wall thickness only in subareas or in all areas. In particular in the case of small wall thicknesses, the advantage of a low thermal and mechanical load carries particular weight.
[0161] In a preferred embodiment example, the carrier 3 has a frame or other elevations (e.g. fastening elements) with a height of at most 100 mm, preferably of at most 50 mm, particularly preferably of at most 20 mm. Here, in particular despite a comparatively poor handling, a rapid, safe and reproducible processing is guaranteed because of an advantageously automated method or an advantageously automated device.
[0162] It is also possible for the carrier 3 to have been decorated on the front and/or on the back. It is also possible for the component part 1 to be decorated on the front and/or on the back after the application of the label 2 to the carrier 3.
[0163] As is moreover illustrated by FIGS. 2a to 2c, it is possible for the optional contacting tail 21 to be free of adhesive 4 and material of the carrier 3. With the contacting tail 21, for example, a coupling to an electronic component part can thus be effected or the component part 1 can be integrated in an electronic component part.
[0164] The carrier 3 preferably has at least one curved surface, which lies for example in the curvature area 53 in FIG. 2a. In this example, the curvature area 53 is delimited by the frame of the component part 1 or of the carrier 3. In the area of the curvature area 53, the label 2 has been applied, which likewise has a curved surface, which is present in the curvature area 52 of the label. The curvature area 52 of the label can cover the entire label 2 or, as is to be seen e.g. in FIG. 2a, only a subarea of the label 2. The curved surface of the carrier 3 is for example already present when the carrier 3 is provided. The curved surface of the label 2 is preferably first formed by the receiving of the label 2 with the label receiver 20, as is illustrated for example by FIGS. 3a and 3b.
[0165] As is illustrated in particular by FIG. 2a and FIG. 2c, it is possible for example for the label 2 and/or the carrier 3 not to have a purely rectangular or purely circular contour. It is also possible for the label 2 and/or the carrier 3 to have a surface area, in particular when viewed perpendicular to a plane spanned by the label 2 and/or the carrier 3 and/or disregarding the thickness of the label 2 and/or of the carrier 3, which comprises a contour of a part or whole of one or more of the following shapes at least in areas: circle, ellipse, triangle, rectangle, alphanumeric character, fractal shape. In a top view of the label 2 shown by way of example by FIG. 2a, for example a contour consisting of a part of a rectangle and a part of a circle or an ellipse would be able to be seen. It is not illustrated by FIGS. 2a to 2c but also possible that the carrier 3 additionally has elevations and/or indentations and/or openings and the label 2 has been or is adapted to such a carrier 3 for example by deformations, which are in particular brought about by the label receiver 20, or by openings present in the label. The contour of the label 2 and/or the carrier 3 can thus also have been formed by openings at least in areas. It is also possible for one or more elevations and/or indentations which are present in the carrier 3 to be filled by the adhesive 4, wherein the label 2 has for example a curved surface which has been or is adapted to an entirety of curvature, indentations and/or elevations of the carrier 3, as is to be seen for example in FIG. 4b.
[0166] FIGS. 3a to 3i show, schematically, the steps of an example method for producing the component part 1 by means of a device. The device has a label receiver 20, a carrier receiver 30 and an adhesive dispensing unit 40. In the example method, the following steps are carried out, preferably in the specified order.
[0167] The steps a1) and a2) as well as b1 and b2) described below are illustrated by way of example by FIG. 3a and FIG. 3b as well as FIG. 3c. In the lower two images FIG. 3a shows a top view of the label receiver 20 and a top view of the label 2. In the lower image FIG. 3b shows a top view of the label receiver with the label 2.
[0168] Step a1) Providing a label 2. The label 2 has a flexible layer structure. The label 2 comprises at least one carrier layer, such as the carrier layer 23, and in addition comprises a further layer, such as for example the electrically conductive functional layer 22, wherein the carrier layer 23 and the functional layer 22 are illustrated for example with reference to one of FIGS. 4a, 4b, 8a to 8g. As an alternative to the further layer, in particular to the functional layer 22, or in addition thereto, it is possible for the label 2 to have one or more electrical and/or electronic and/or optical and/or optoelectronic components, such as are illustrated by way of example with reference to the components 261 of FIG. 8c or 8g. The label can furthermore have been constructed in particular as is described in more detail for example in relation to FIGS. 7a to 7c and FIGS. 8a to 8g. Optionally, the label 2 has a contacting tail 21. Possible designs of the contacting tail are is described in more detail for example in relation to FIGS. 7a to 7c.
[0169] Step a2) Receiving the label 2 with the label receiver 20.
[0170] The label 2 shown in FIG. 3a can be provided for example manually and/or by means of a robot arm, in particular in or from a magazine. After the provision, a vacuum is for example generated by the label receiver 20, in particular by means for generating a vacuum which are exhibited by the label receiver 20, with the result that the label 2 is suctioned by the label receiver 20. As is illustrated by FIGS. 3a and 3b, it is possible for the label receiver 20 to have a fitted shape adapted to the shape of the label 2. During the receiving of the label 2 it is preferably possible for the label 2 to be curved and to adopt a shape following the contour of the label receiver 20. For this, a vacuum, which suctions the label 2, can for example be generated by means of the label receiver 20. In this example the label receiver 20 has the curvature area 520, which comprises a curved surface. Because the label 2 is received, in particular is suctioned, in this area 520, the label 2 is deformed and the curvature area 52 of the label 2 is formed with a corresponding curved surface. The curved surface of the label 2 in the curvature area 52 has been adapted in particular depending on a curved surface of the carrier 3, such as is present for example in the curvature area 53 of the carrier. By way of example, such curvature areas are also described FIG. 2a to FIG. 2c. Thus, through a defined relative movement, such as is described in more detail by way of example in relation to FIG. 3f, the adhesive 4 provided between the label 2 and the carrier 3 can be displaced in a controlled manner and the one or more adhesive layers, in particular the adhesive layer 41, can be formed.
[0171] It is also possible for the label receiver 20, as an alternative or in addition to the means for generating a vacuum, to have for example a mechanical holder and/or a clamp for receiving the label 2.
[0172] The label receiver 20 is preferably connected to a robot system, which makes it possible to move the label receiver 20 to different positions for carrying out the respective steps. With respect to the robot system, reference is made in particular to the above statements.
[0173] The provision of the label 2 is effected before the label 2 is received with the label receiver 20. The provision of the carrier 3 is effected before the carrier 3 is received with the carrier receiver 30, wherein it is possible for the receiving of the label 2 to be carried out first or for the receiving of the carrier 3 to be carried out first or for both to be carried out simultaneously.
[0174] FIG. 3c illustrates an example of the step c) described below.
[0175] Step c) Applying, by means of the adhesive dispensing unit 40, a flowable adhesive 4, in one or more first defined shapes, to the label 2 held by means of the label receiver 20. Example defined shapes of the adhesive 4 are described in relation to FIG. 6. It is alternatively or additionally possible to apply the adhesive 4 to the carrier 3 held by means of the carrier receiver 30. It is thus also conceivable that the one or more first defined shapes of the adhesive 4 are composed of one or more partial shapes on the label 2 and one or more partial shapes on the carrier 3. As is illustrated by FIG. 3c, it is preferably possible for the adhesive dispensing unit 40 to have at least one nozzle and/or at least one dispenser for applying the adhesive 4. The label receiver 20 is preferably guided to the adhesive dispensing unit 40 in particular by means of a robot system. In particular, to apply the adhesive 4, the label receiver 20 is then moved corresponding to a shape to be applied, preferably the one or more first defined shapes, of the adhesive 4 while the adhesive dispensing unit 40 dispenses the adhesive 4 onto the label 2 and is preferably held motionless in the process. It is also conceivable that the adhesive dispensing unit 40 is moved corresponding to a shape to be applied, preferably the one or more first defined shapes, of the adhesive 4 while the adhesive dispensing unit 40 dispenses the adhesive 4 onto the label 2 and the label receiver 20 is preferably held motionless in the process.
[0176] FIG. 3d) shows the carrier 3 received on the carrier receiver 30 with an optional pretreatment unit 80. By way of example, the following examples of steps b1) and b2) are illustrated hereby.
[0177] Step b1) Providing a carrier 3. The carrier 3 has been constructed for example as is described in more detail in relation to one of FIGS. 2a to 2c, 7a to 7c and 8a to 8g. The provision of the carrier 3 is effected for example by means of a manual placement on the carrier receiver 30 and/or by means of a placement on the carrier receiver 30 by a robot arm.
[0178] Step b2) Receiving the carrier 3 by means of the carrier receiver 30.
[0179] FIG. 3d additionally illustrates an optional step x1), which is preferably carried out before step d).
[0180] Step x1) Pretreating the carrier 3 by means of a pretreatment unit 80, for example by blowing ionized air against the carrier 3 and/or by a plasma treatment and/or a corona treatment and/or by a chemical cleaning, e.g. with alcohol. The pretreatment unit 80 is or comprises for example individually or in combination: an ionizer and means for blowing ionized air against the carrier 3, a device for plasma treatment, a device for corona treatment, a device for cleaning with chemicals, e.g. with alcohol.
[0181] FIG. 3e and FIG. 3f show an example of the step d) described below.
[0182] Step d) Laying the label 2 and the carrier 3 one on top of the other by means of a defined relative movement of the label receiver 20 and the carrier receiver 30, such that the adhesive 4 is arranged between the label 2 and the carrier 3 and one or more adhesive layers, in particular the adhesive layer 41, preferably in one or more second defined shapes, are obtained between the label 2 and the carrier 3. Here, in particular in the case of complex geometries of the carrier 3, the one or more first defined shapes of the adhesive 4 and the relative movement of the label 2 and the carrier 3 can be matched to each other in a targeted manner, with the result that the one or more adhesive layers, in particular the adhesive view 41, results from this. The relative movement preferably comprises a rotational movement in the example shown by FIG. 3f. In particular, the relative movement is an optional seesawing movement. The movement is indicated by the arrow 45. This relative movement advantageously makes a targeted and/or defined displacement of the flowable adhesive 4 possible. Specific optional embodiments of the one or more defined first shapes of the adhesive and the relative movement are described in particular in relation to FIG. 6. The laying of the label 2 and the carrier 3 one on top of the other is preferably effected such that the one or more adhesive layers, in particular the adhesive layer 41, have been or are arranged with a minimum thickness of 5 ?m between the label 2 and the carrier 3.
[0183] As is illustrated by way of example with reference to a comparison of FIGS. 3e and 3f with FIGS. 4a and 4b, it is possible for the one or more first defined shapes to be formed by one or more first layers of the adhesive 4, wherein these one or more first layers of the adhesive are applied over part of the surface, and during the laying of the label 2 and the carrier 3 one on top of the other a displacement of the adhesive 4 results in a greater surface coverage and/or a surface coverage over the whole surface. Through the displacement of the adhesive 4, one or more adhesive layers, in particular the adhesive layer 41, distributed bubble-free and uniformly are thus advantageously obtained.
[0184] The label receiver 20 is preferably guided to the carrier receiver 30 in particular by means of a robot system, in particular as a part of the defined relative movement of the label 2 and/or the carrier 3, or the defined relative movement is carried out and/or continued thereafter.
[0185] FIG. 3g shows an example of an optional step x2) described below.
[0186] Step x2) Precuring the one or more adhesive layers over part of the surface.
[0187] It is possible for the device to have a precuring unit 60 as shown by way of example in FIG. 3g for partially precuring the one or more adhesive layers, in particular while the label receiver 20 is in contact with the label 2. The precuring unit 60 is preferably an irradiation unit, in particular for irradiation with UV radiation, preferably UV-A, UV-B and/or UV-C radiation, and/or with visible light and/or by means of IR radiation. In particular, a UV emitter with a focused irradiation is preferred for the example illustrated by FIG. 3g. It is also conceivable that the precuring is carried out over the whole surface, because the label receiver 20 has been formed completely transparent for the corresponding irradiation. In particular, the label receiver has at least one or more transparent, preferably UV-transparent, areas and/or one or more holes, and/or the one or more adhesive layers, in particular the adhesive layer 41, are irradiated or can be irradiated through the one or more transparent areas and/or holes, in particular while the label receiver 20 is still in contact with the label 2. It is thus possible for the radiation of the precuring unit 60 thus preferably to pass through the transparent areas and/or the holes before the radiation strikes the one or more adhesive layers, in particular the adhesive layer 41. This makes it possible to increase the adhesion between the label 2 and the carrier 3 before the label 2 is taken off the label receiver 20. Thus, the label receiver 20 can in particular be taken off the label 2 safely, reliably and in a manner that is gentle on the one or more adhesive layers. The one or more adhesive layers, in particular the adhesive layer 41, preferably have been or are not yet completely cured or not yet completely crosslinked by the precuring at least in areas. A sufficient fixing for safely taking off the label receiver 20 can advantageously already be achieved hereby.
[0188] FIG. 3h shows an example of an optional step x3) described below.
[0189] Step x3) Detaching the label 2 from the label receiver 20.
[0190] For this, the label receiver 20 is moved away from the label 2. It is possible for example for the vacuum to be ceased and/or a pressure to be increased on the label receiver 2.
[0191] FIG. 3i) shows by way of example the step e) described below.
[0192] Step e) At least partially curing and/or at least partially crosslinking the one or more adhesive layers, in particular the adhesive layer 41.
[0193] It is possible here for the curing to be carried out by means of irradiation, preferably UV radiation, preferably UV-A and/or UV-B and/or UV-C radiation, and/or with visible light and/or IR radiation, as is illustrated in particular by FIG. 3i). However, it is also conceivable that the adhesive 4 or the one or more adhesive layers formed therefrom, in particular the adhesive layer 4, are self-curing, preferably with the result that the step of curing and/or crosslinking can be carried out for example by waiting and/or starts up spontaneously, preferably as soon as the adhesive 4 has been applied.
[0194] After the curing, the component part 1 produced can be removed from the device.
[0195] The device according to the invention for producing the component part 1 preferably serves and/or has been configured to carry out the method. As is shown for example by FIGS. 3a) to 3i) and described in relation thereto, the device comprises: the label receiver 20 for receiving the label 2. The label 2 has a flexible layer structure. The label comprises at least one carrier layer, such as for example the carrier layer 23 and a further layer, such as for example the electrically conductive functional layer 22. As an alternative to the further layer, in particular to the functional layer 22, or in addition thereto, it is possible for the label 2 to have one or more electrical and/or electronic and/or optical and/or optoelectronic components, such as by way of example the components 261. Optionally, the label 2 has a contacting tail 21. The label 2 can furthermore have been constructed in particular as is described in more detail for example in relation to FIGS. 7a to 7c and FIGS. 8a to 8g. In addition, the device comprises the carrier receiver 30 for receiving the carrier 3 and an adhesive dispensing unit 40 for applying the flowable adhesive 4 to the label 2 in one or more first defined shapes by means of the adhesive dispensing unit 40. It is alternatively or additionally also possible for the flowable glue 4 to be able to be applied to the carrier 3 in one or more first defined shapes by means of the adhesive dispensing unit 40. The device has been configured such that a laying of the label 2 and the carrier 3 one on top of the other can be carried out by means of a defined relative movement of the label receiver 20 and the carrier receiver 30. Through this relative movement, an arrangement of the adhesive 4 between the label 2 and the carrier 3 is possible such that one or more adhesive layers, preferably the adhesive layer 41, in particular in one or more second defined shapes, can be obtained between the label 2 and the carrier 3.
[0196] It is also possible for the device to have an optional curing unit 70 for at least partially curing the one or more adhesive layers, preferably the adhesive layer 41.
[0197] FIGS. 4a and 4b show schematic examples of a cross section of a produced component part 1.
[0198] FIG. 4a shows for example a schematic cross section through a component part 1 as described in relation to FIGS. 2a to 2c. The label 2 has for example a curved surface complementary to the carrier 3. A component part 1 as illustrated by way of example by means of FIG. 4b has, in particular, indentations and/or elevations in addition to at least one curved surface. It is thus also possible for one or more elevations and/or indentations which are present in the carrier 3 to be filled by the adhesive 4, wherein the label 2 has for example a curved surface which has been or is adapted to an entirety of curvature, indentations and/or elevations of the carrier 3. Here, in particular, a variation in layer thickness of the one or more adhesive layers, in particular the adhesive layer 41, which preferably results from the displacement during the relative movement of the label 2 and the carrier 3, has been or is formed.
[0199] As is shown by FIG. 4a and FIG. 4b by way of example, a component part 1 is thus possible which has been or is preferably produced by means of the method according to the invention and/or by means of the device according to the invention. The component part 1 comprises a label 2. The label 2 comprises at least one carrier layer, such as the carrier layer 23, and a further layer, such as the electrically conductive functional layer 22. As an alternative or in addition to the further layer, the label 2 comprises one or more electrical and/or electronic and/or optical and/or optoelectronic components, such as the components 261. Furthermore, the component part 1 comprises a carrier 3 as well as one or more adhesive layers, such as the adhesive layer 41, which are arranged between the label 2 and the carrier 3. The one or more adhesive layers, such as the adhesive layer 41, have been applied as a flowable adhesive 4, then displaced by a defined relative movement of the label 2 and the carrier 3 and subsequently cured and crosslinked. The carrier 3 here has an in particular complex shape, because the surface to be coated has for example steps 301, an indentation 302 as well as an elevation 303. In particular through the arrangement between the label 2 and the carrier 3 and the application of the glue 4 in a flowable form with the subsequent displacement, the one or more adhesive layers are thus distributed on the coated surface of the carrier 3 such that the elevations 303 and indentations 301 as well as the radii on the steps 301 are completely filled, which is achieved in particular by a variation in layer thickness of the adhesive layer 41, which preferably results because of the flowability of the adhesive 4 during the laying of the label 2 and the carrier 3 one on top of the other. In addition, a nuisance particle 304 is arranged between the label 2 and the carrier 3. This nuisance particle 304 is advantageously enclosed, without bubble formation, by the adhesive 4 or the one or more adhesive layers obtained therefrom, in particular the adhesive layer 41. As is illustrated hereby, it is thus possible for one or more nuisance particles enclosed bubble-free to be present in the one or more adhesive layers and/or for a surface of the carrier which is provided bubble-free with one or more adhesive layers and which has unevennesses, steps, indentations and/or elevations to be present. The adhesive layer 41 preferably has a thickness which is at least 30% greater than the height or depth of the structure to be compensated for in each case (here by way of example: step 301, indentation 302, elevation 303, nuisance particle 304).
[0200] FIG. 5 shows an example of a method with the steps, in particular in the specified order:
[0201] Step 1001: Providing the label 2, which has a flexible layer structure and preferably is or comprises a sensor film, manually and/or by means of a robot arm, in particular in or from a magazine, and the carrier 3 by means of a manual placement on the carrier receiver and/or by means of a placement on the carrier receiver by a robot arm.
[0202] Step 1002: Optionally pretreating the carrier, for example by means of treatment with ionized air, corona treatment and/or plasma treatment and/or cleaning with chemicals, e.g. with alcohol.
[0203] Step 1003: Receiving the label 2 by means of the label receiver 20, in particular by suction by means of a vacuum,
[0204] Step 1004: Applying the flowable adhesive 4 to the label 2
[0205] Step 1005: Laying the label 2 on top of the carrier 3, in particular by means of a movement of the label receiver 20.
[0206] Step 1006: Optionally precuring the adhesive 4 or the one or more adhesive layers obtained therefrom, in particular the adhesive layer 41, preferably wherein the precuring takes place only in a subarea and/or takes place by means of irradiation through the label receiver 20 and/or one or more holes of the label receiver 20.
[0207] Step 1007: Moving the label receiver 20 away from the label 2, in particular through a movement of the label receiver 20.
[0208] Step 1008: Curing and/or completely crosslinking the one or more adhesive layers, in particular the adhesive layer 41.
[0209] Step 1009: Optionally removing the component part 1 from the carrier receiver 30, for example manually, by means of a robot arm, by means of a removal means and/or by means of the label receiver. It is also possible here for a transfer of the component part 1 to be effected for example by means of an X/Y or X/Y/Z shift mechanism, for example to be effected onto a conveyor belt and/or onto and/or into a housing.
[0210] Step 1010: Optionally checking the component part 1 by means of optical inspection by means of cameras and/or optical sensors or visual inspection by a human and/or by means of one or more sensors. Here, in particular, measured values with respect to the geometry, transmittance, electrical capacitance, electrical resistance, are compared with a target value. The device preferably has means for comparing the values measured by means of the one or more sensors with a target value.
[0211] Step 1011: Optionally placing the component part 1, in particular manually and/or by means of a robot arm and/or by means of an X/Y or X/Y/Z shift mechanism or by means of conveyors, for example at a storage location and/or in a package.
[0212] The device has been configured in particular for carrying out one or more of the step 1001 to 1011, in particular step 1005, in an automated manner.
[0213] FIG. 6 shows, schematically, an example of a label 2, on which the adhesive 4 has been or is deposited. It is in particular a top view and/or a view perpendicular to a plane spanned by the example label 2. As is shown by way of example by FIG. 6, it is possible for the adhesive 4 to have been or to be applied to the label 2 over part of the surface. The adhesive 4 has one or more first defined shapes. It is possible in particular for the first defined shapes of the adhesive 4 to have one or more of the following shapes: straight and/or curved lines, bone structure, T shape, Y shape, I shape, U shape, serpentines, nodes, branches, fractal shapes.
[0214] It is possible in particular for the one or more first defined shapes to have cross-section dimensions, in particular diameter, in a range of from 50 ?m to 5,000 ?m, preferably in a range of from 500 ?m to 3,000 ?m. For example, the adhesive is applied as a bead. A preferred range of the viscosity lies in a range of from 500 mPa.Math.s to 2,000 mPa.Math.s, further preferably in a range of from 1,000 mPa.Math.s to 1,500 mPa.Math.s. It is advantageously guaranteed that the adhesive remains stable in the one or more first defined shapes. The adhesive 4 preferably has been or is applied with a width in a range of from 100 ?m to 10,000 ?m, preferably in a range of from 1,000 ?m to 6,000 ?m. The width is preferably measured in a top view and/or when viewed perpendicular to a plane spanned by the label 2 or the carrier 3, thus in particular when viewed as shown in FIG. 6.
[0215] A preferred adhesive has a temperature resistance of from ?50? C. to 150? C. and/or a flash point of over 100? C. and/or a refractive index (nD20) in a range of from 1 to 2, preferably 1.2 to 1.8, preferably from 1.46 to 1.48.
[0216] As is illustrated by FIG. 6 by way of example, it is possible for adhesive 4 to have been or to be applied exclusively to the label 2 in step c). However, it is also conceivable that in step c) one or more first layers of the adhesive 4 are applied to the label 2 partially, in particular over a small area, and one or more second layers of the adhesive 4 are applied to the carrier 3 over the whole surface and/or over a large area or one or more first layers of the adhesive 4 are applied to the carrier 3 partially, in particular over a small area, and one or more second layers of the adhesive 4 are applied to the label 2 over the whole surface and/or over a large area.
[0217] In addition, it is conceivable that the adhesive 4 is applied to the label 2 and a primer has been or is applied to the carrier 3 or a primer has been or is applied to the label 2 and the adhesive 4 is applied to the carrier 3.
[0218] With respect to the composition of the adhesive 4, reference is made in particular to the above statements. It is preferably an adhesive crosslinkable by means of UV radiation and/or with visible light.
[0219] During the laying of the label 2 and the carrier 4 one on top of the other, the adhesive is in particular further distributed between the label 2 and the carrier 4, from which the one or more adhesive layers 41 with one or more second defined shapes result, with the result that preferably the layer thickness of the first defined shapes is greater at least in areas than the layer thickness of the second defined shapes and/or in a top view the area of the first defined shape is greater than the area of the second defined shapes. As is also illustrated by FIG. 6 by way of example, it is possible for the surface density of the first defined shapes relative to the surface area covered with the one or more adhesive layers 41 after the label 2 and the carrier 3 have been laid one on top of the other to be less than 90%, preferably less than 80%. It is expedient that the surface density of the one or more first shapes is at least 5%.
[0220] An example defined relative movement of the label 2 and the carrier 3 is indicated here in particular by the arrow 45, wherein the arrow specifies the starting point of a contact of the label 2, the adhesive 4 and the carrier 3 and the direction of areas in which a contact of the label 2, the adhesive 4 and the carrier 3 is subsequently produced. The sequence shown can be achieved for example by a rotational movement of the label receiver 20, in particular a seesawing movement and/or an unrolling movement. By contact is meant here in particular that a line, preferably a vertical line, which extends through the label 2, the adhesive 4 and the carrier 3, can be formed in a cross section, for example a cross section as shown in relation to FIG. 3f.
[0221] As is illustrated in addition by FIG. 6 by way of example, it is possible for the adhesive 4 to be deposited inside one or more first areas, such as the area 400, of the label 2 for each area of the one or more first areas, thus here in the area 400, in an initial area 401 and in a following area 403 of the label 2. During the laying of the label 2 and the carrier 3 one on top of the other a contact of the label 2, the adhesive 4 and the carrier 3 is is produced in the initial area 41 first and then, preferably lastly, in the following area 403. The adhesive 4 with the one or more first defined shapes has a higher surface density in the initial area 401 than in the following area 403.
[0222] In the case of a depositing of the adhesive 4 onto the carrier, such areas can be defined analogously.
[0223] The initial area 401 can be formed for example by a proportion of at most 20% of the total surface area of the label which has a connection of label 2, adhesive 4 and carrier 3 in the respective first area first. The following area 403 can be formed for example by a proportion of at least 80% of the total surface area of the label which has a connection of label 2, adhesive 4 and carrier 3 in the respective first area last. The one or more first defined shapes can in particular also not be provided in the following area 403 and adhesive 4 can first be distributed by being displaced thereto. It is conceivable that there is only one first area 40, as is illustrated by way of example by FIG. 6. It is also possible for an intermediate area 402 to be present for example between the initial area 401 and the following area 403. The surface density is preferably lower in the intermediate area 402 than in the initial area 401 and can be lower or higher than in the following area 403.
[0224] The surface density is preferably calculated when viewed perpendicular to a plane spanned by the label and/or the carrier. The surface density is preferably calculated from the area of a surface area covered by adhesive 4 in the first defined shapes in relation to the surface area of the label 2 and/or of the carrier 3 which is provided with the adhesive 4 in the second defined shape or with the one or more adhesive layers 41 after the label 2 and the carrier 3 have been laid one on top of the other.
[0225] The adhesive 4 with the one or more first defined shapes preferably has been or is with a distance of at least 1 mm, preferably at least 2 mm, from an outer edge and/or from an outer rim of a surface of the label 2 and/or of the carrier 3 and/or from an edge of an opening inside the label 2 and/or the carrier 3 to which the adhesive 4 is applied.
[0226] FIG. 7a shows, schematically, a top view of an example label 2 and/or a view perpendicular to a plane spanned by an example label 2. The label 2 comprises the optional contacting tail 21, which is arranged at least in a contact area 211. As is shown in this way in particular by FIG. 7a by way of example, it is possible for the label 2 to have an optional contacting tail 21 for contacting, in particular electrically contacting, the further layer, in particular the electrically conductive functional layer 22, and/or the one or more electrical and/or electronic and/or optical and/or optoelectronic components 261. As is shown in addition by FIG. 7a by way of example, it is possible for the label 2 to have conductive tracks 221 and touch areas 222, preferably for touch sensors, in particular with capacitive elements for touch sensors, which are contactable via the conductive tracks 222 by means of the contacting tail 21. At least such conductive tracks 221 and/or touch areas 222 are preferably comprised by the functional layer 22. It is possible for one or more touch areas to be formed. The one or more touch areas have preferably been provided over part of the surface and in particular adapted in terms of their shape to operating functions of the component part. Conductive structures, in particular consisting of structured metal surfaces (for example as a regular or irregular preferably fine grid) or of preferably very thin metal surfaces or of transparent electrically conductive substances, such as e.g. electrically conductive metal oxides, such as ITO (indium tin oxide), and/or of electrically conductive plastics, such as PEDOT, which are preferably designed transparent and/or appearing transparent to the human eye, are preferably present in the touch areas 222. It is thus possible for the label 2 to comprise or to have been formed by, in particular, a sensor film, wherein the sensor film preferably forms a sensor function, preferably a touch sensor function. The sensor function, preferably touch sensor function, has been or is provided, in particular, by means of the electrically conductive functional layer of the label. It is possible for the sensor film and/or the electrically conductive functional layer, in particular the one or more conductive tracks and/or the one or more capacitive elements, and/or the carrier layer to be transparent and/or to be non-transparent, in particular opaque.
[0227] FIG. 7c shows by way of example the contact area 211 in a schematic cross section through the label 2 of an area which is labeled from C to D in FIG. 7a. FIG. 7b shows by way of example a schematic cross section through the label 2 in the area from A to B in FIG. 7a. For example, the upper side shown in the cross section or the lower side has been provided for connection to the carrier 3. The one or more adhesive layers 41 are thus formed on this side, in particular through the laying of the label 2 and the carrier 3 one on top of the other. The cross section in FIG. 7b thus shows for example only the sensor area 201, wherein the cross section in FIG. 7c shows both the sensor area 201 and the contact area 211.
[0228] The contacting tail 21 preferably has a smaller surface area than the rest of the label 2, in particular when viewed perpendicular to a plane spanned by the label 2. In the method the contacting tail 21 preferably is and/or remains free of adhesive 4, preferably free of adhesive 4 and/or free of material of the carrier 3 at least in a contact area 211, and/or the device, in particular the carrier receiver and the label receiver, has been configured such that this is possible.
[0229] In particular, the one or more first defined shapes of the adhesive 4 are applied with an adapted shape and amount, for example to form beads in a bone structure, and in particular the contact area 211 is left free of adhesive 4, as is to be seen for example in FIG. 6. The defined relative movement of the label 2 and the carrier 3 preferably has been or is adapted, in particular by means of a lifting movement and/or a seesawing movement, with the result that the contact area 211 remains free of adhesive 4, in particular even if a displacement of the adhesive 4 takes place. The contacting tail 21 is held on the label receiver 20 preferably in a defined position, in particular during the laying of the label 2 and the carrier 3 one on top of the other. For this, the label receiver can for example have means for suctioning the contacting tail 21 by means of a vacuum, one or more clamping devices and/or one or more spacers.
[0230] At least one subarea of the contact area 211 is suitable for the electrical contacting of the functional layer 22 and/or of the one or more electrical and/or electronic and/or optical and/or optoelectronic components. As is shown by way of example by FIG. 7a, it is possible for a subarea 212 of the contact area 211 of the contacting tail 21 to have a reinforcing element 213. Such a reinforcing element is in particular also called a stiffener. The reinforcing element 213 preferably has been or is connected to the label 2 via a glue 214, which is in particular also called a stiffener glue, as is illustrated by way of example with reference to FIG. 7c. In particular in the subarea 21, an electrical contacting of the functional layer 22 can thus be produced. FIGS. 7a, 7b, and 7c furthermore show by way of example a sensor area 201, which preferably represents an area connected or to be connected to the carrier 3 and is present neighboring the contact area 211. The one or more adhesive layers, in particular the adhesive layer 41, are preferably formed in the sensor area 201. The contacting tail 21 thus preferably provides an electrical contacting possibility on a side of the contacting tail 21 facing away from the sensor area 201. For this, at least one electrically conductive layer of the functional layer 22 preferably extends from the sensor area 201 into the contacting area 211.
[0231] FIG. 8a schematically shows an example of a cross section of a label 2 with a complex layer structure. The label 2 can for example be multi-layered, as is illustrated by the layers 2001 to 2002. One or more layers of the label 2, in particular all layers of the label 2, can also be present in the contact area 211 and/or in the contacting tail 21. The underside of the label 2 is provided with adhesive 4 and connected to the carrier 3. During the method, for example, the upper side comes directly into contact with the label receiver 20. Preferably, one of the layers 2001 to 2004 has been formed as the at least one carrier layer and another of the layers 2001 to 2004 has been formed as the further layer. The remaining layers are optional. As an alternative or in addition to the further layer, however, one or more components can also have been arranged on the carrier layer, for example the components 261 shown in FIG. 8c and FIG. 8g.
[0232] FIG. 8b shows, schematically, a cross section of a label 2 with the following layer sequence: a protective layer 24, the functional layer 22, which here is preferably a sensor layer 22 with one or more electrically conductive layers, the carrier layer 23, a primer 25. The primer 25 represents in particular an adhesion-promoter layer 25. It is conceivable that the further layer comprises or is formed by the primer 25 and the remaining layers on the other side of the carrier layer 23 are optional. Alternatively, the primer 25 is optional and the further layer is at least one other layer which is present in particular on the side of the carrier layer 23 opposite the primer 25.
[0233] The protective layer 25 is for example a varnish layer or a film. It is possible for the protective layer to have been firmly integrated in the label 2 or for the protective layer 24 to have been designed detachable, in particular with the result that the protective layer 24 can be detached after the label 2 has been detached from the label receiver 20. The carrier layer 23 is for example a film substrate and/or comprises one or more of the following materials: PET, PC, PMMA, ABS, PC-ABS, PP, PA, PE. It is also conceivable that one or more color layers have been provided instead of the protective layer 24 or between the protective layer 24 and the functional layer 22. The further layer can here comprise one or more of the layers 22 and 24, wherein the remaining layer not comprised by the further layer is optional.
[0234] FIG. 8c shows a schematic cross section of a label 2 as described in relation to FIG. 8b, except that between the protective layer 24 and the functional layer 22 a functional layer 26 has been provided, which comprises one or more components 261, preferably hybrid components, for example selected individually or in combination from: passive components, active components, LEDs, OLEDs, sockets, controllers, processors, resistors, display elements, plugs, sensors, actuators, capacitors, etc. The components have preferably been encapsulated by means of a plastic material, preferably encapsulated by means of polyurethane (PUR). It is also conceivable that the further layer comprises or consists of a functional layer, such as for example the functional layer 26, which comprises and/or encapsulates in particular the one or more electrical and/or electronic and/or optical and/or optoelectronic components, such as the components 261. The further layer can comprise in particular one or more of the layers 22, 24 and 26, wherein the remaining layers not comprised by the further layer are optional.
[0235] FIG. 8d shows a schematic cross section of a label 2 as described in relation to FIG. 8b, except that here a functional layer 27 with an optical function has been provided instead of a functional layer 22, which is preferably a sensor layer 22 with one or more electrically conductive layers. The optical function can in particular be a decoration and/or a display by means of a screen. In particular, the optical functional layer 27 comprises or preferably consists of one or more of the following components: polarizer, color filter, diffuser, privacy filter, anti-reflective layer, anti-reflection coating. In addition, the label 2 here has one or more decorative layers 28, which are arranged for example between the functional layer 27 and the carrier layer 23. The one or more decorative layers 28 preferably comprise or preferably consist of one or more of the following layers: layer with an endless pattern, layer with a single image, partial layer, whole-surface layer, metal layer, color layer, preferably colored varnish layer, in particular full-tone colored varnish layer and/or halftone colored varnish layer, preferably colored varnish layer with a print raster, varnish layer with a relief structure imprinted therein, reflective layer, in particular metal layer or HRI layer (HRI=High Refractive Index).

The one or more color layers can in particular have been formed as described in relation to FIG. 8e. The functional layer 27 can in particular have been formed as in relation to FIG. 8d. The functional layer 27 of the example in FIG. 8f is in particular a diffuser layer, which is preferably present over the whole surface or partially, in particular patterned. A diffuser layer can for example have been or be formed by a diffuser varnish. Instead of the diffuser layer of the label described in relation to FIG. 8f, for example a layer 26 as described in relation to FIG. 8c can also have been provided. The further layer can in particular comprise one or more of the layers 22, 27 and 29, wherein the remaining layers not comprised by the further layer are optional.
[0238] FIG. 8g shows a schematic cross section of a label 2 as described in relation to FIG. 8b, except that a second protective layer 241 has been provided on the side of the primer 25 facing away from the protective varnish 24, and the following layer sequence has been provided between the protective layer 24 and the primer 25, in particular starting from the protective layer 25: [0239] one or more color layers 29, in particular a shadow mask, [0240] a functional layer 27, which is preferably a diffuser layer 27, [0241] a functional layer 26, which preferably comprises one or more components, as is described in particular in relation to FIG. 8c for the functional layer 26, [0242] a contacting layer 31, in particular for electrically contacting the one or more components 261 of the functional layer 26 and/or for electrically contacting the functional layer 22, [0243] one or more first intermediate layers 32, for example comprising one or more insulators and/or one or more dielectrics, [0244] a further functional layer 33, for example comprising sensors, [0245] one or more second intermediate layers 34, for example comprising one or more insulators and/or one or more dielectrics, [0246] the functional layer 22, which here is preferably a sensor layer 22 with one or more electrically conductive layers and in particular can have been formed as described in relation to FIG. 8b, [0247] the carrier layer 23, which can in particular have been formed as described in relation to FIG. 8b, [0248] one or more third intermediate layers 35, for example comprising one or more insulators and/or one or more dielectrics, [0249] a further diffuser layer 271, [0250] the one or more decorative layers 28, which can in particular have been formed as described in relation to FIG. 8d, [0251] a third protective layer 242, which can in particular have been formed of a protective varnish or a protective film, [0252] the primer 25, which can in particular have been formed as described in relation to FIG. 8b.
[0253] The intermediate layers 32, 33 and 34 can thus act in particular as an electrically insulating functional layer.
[0254] The one or more decorative layers 28 here preferably are or comprise a shadow mask.
[0255] The contacting layer 31 extends for example through the sensor area 201 as well as the optional contacting tail 21 or contact area 211. It is also possible for layers lying between the functional layer 22 and the contacting layer 31 and/or between the functional layer 33 and the contacting layer 31 to have through-connections, in particular such that the contacting layer 31 and the functional layer 22 are electrically conductively connected and/or galvanically connected.
[0256] A shadow mask is in particular a partially provided opaque layer.
[0257] The further protective layer 241 is in particular a protective film. The second protective layer 241 is preferably detachable from the label 2. In particular, the second protective layer 241 is detached before the glue 4 is deposited on the label 2 and/or before the label 2 and the carrier 3 are laid one on top of the other.
[0258] The further layer can in particular comprise one or more of the layers 24, 29, 27, 26, 31, 31, 33, 34, 22, 23, 35, 271, 28, 242, 25, 241, wherein the remaining layers not comprised by the further layer are optional.
