THE PREFERRED EMBODIMENTS
(37) To further explain the technical means and the effects this invention has adopted to achieve its predetermined objectives of invention, a detailed explanation, complemented with illustrations and the relatively better examples of implementation, of the product and the method of the cloth electronization proposed in this invention and the specific ways of implementation, method, procedures, structures, characteristics and effects, is as follows.
(38) What has explained about this invention and other technical contents, characteristics and effects will be clearly presented in the detailed explanation of the relatively better examples of implementation, illustrated in reference schemes. Via the explanation of specific method of implementation, a much deeper and more specific understanding of the technical means and the effects this invention has adopted to realize its predetermined objectives. However, the complementary illustrations only serve as references and explanations, and are not intended to restrict this invention.
(39) The method of this invention is illustrated in
(40) In this method, the cloth electronization mainly uses non-conductive wire such as yarn 6 to stitch electronic module 3 to the packaging cloth 1. Moreover, rather than using the way of stitching the yarn, electronic modules can be directly used to “glue”, onto the packaging cloth. As to the transmission wires, they can be stitched to or glued to the cloth, and the ways of stitching can be further divided into: the transmission wires themselves stitch into the cloth 1, or use conductive or non-conductive wires like yarn 6 to stitch the transmission wire 2, as illustrated in
(41) Another method in this invention is as illustrated in
(42) Another type of transformation involves the packaging cloth or the cloth for attire 1 that has cracks in itself, so electronic module 3 is placed on one side of the packaging cloth or the cloth for attire, while the conductive regions are exposed from the cracks on the other side of the packaging cloth or the cloth for attire 1, to connect the transmission wires, as illustrated in
(43) Another way is to use transmission wires 2 and 4 to “entrap” the conductive region 5 in electronic module 3, as illustrated in
(44) Another method uses yarn 6 to stitch electronic module 3 to the packaging cloth or the cloth for attire 1, thus connecting the conductive region 5 in electronic module 3 and the transmission wires 2 or 4, as illustrated in
(45) Another method is that when the transmission wires are stitched to the cloth 1, the transmission wires have multiple threads so that they can entrap the conductive region 5 in electronic module. The ways of entrapping include all-encompassing entrapping, partial entrapping, for example, partially entrap the top and the side, the bottom and the side, the front and the side, the back and the side of the conductive regions, or only the conductive regions on the side and the transmission wires are clipped, forming conditions like all-encompassing entrapping or partial entrapping on the top and on the side, as illustrated in
(46) Another method is to stitch a Velcro 7 (loop) to the packaging cloth or the cloth for attire, to replace the original yarn 6, to fix electronic module 3 and the transmission wire 2, so the conductive regions in electronic modules are connected to the transmission wires, as illustrated in
(47) Another method is to stitch the transmission wire 2 to the packaging cloth or the cloth for attire 1, after passing through or coming into contact with a conductive silicone rubber, conductive multi-molecular cloth, conductive bars or conductive rubber 8, then embed or make the conductive region 5 in electronic module 3 contact conductive silicone rubber or rubber 8, as illustrated in
(48) The method of “stapling 9” can be used to connect another transmission wire 2 and electronic module 3, use stapler 9 to replace yarn 6 for fixation. At that time the “stapler” can be non-conductive material, as illustrated in
(49) All the methods mentioned above are interchangeable. For example, the conductive silicone rubber or rubber 8 and electronic module 3 and the transmission wire 2 can be combined first, and then stitched to the packaging cloth or the cloth for attire 1, meanwhile the transmission wire 2 can have various ways of connecting to various kinds of electronic modules 3. For the same reason, replace “electronic modules” with another “transmission wire” to connect various transmission wires, for example, only knot and twist . . . two transmission wires at crossings to connect two transmission wires in a “T” shape. That is to say, the various ways of connecting “the conductive regions” and the transmission wires are just the way of connecting another transmission wire and the original transmission wire.
(50) For the same reason, the way of connecting the transmission wire 2 and electronic module 3 can be used to connect one electronic module with another; for example, ways of connection in a “T” shape stand for knotting, inter-wreathing, and so on among three electronic modules. Two electronic modules are combined using a way of connection in an “L” shape, and then another conductive region 5 in every electronic module is combined with the transmission wire 2. In the methods mentioned above, the packaging cloth or the cloth for attire can be replaced by the heat melt adhesive film. Do as follows: place the electronic circuits on the heat melt adhesive film to form an electronic circuit board, then merge the heat melt adhesive film into the packaging cloth or the attire for packing and insulation; meanwhile, this electronic circuit merged into the cloth does not show its original structure and depth, producing a minimized effect.
(51) The following are a few examples of relevant applications, the first being a Temperature Coat. We put each pin of 10 Heat Resistance, which are interwoven with conductive region 5 and the enamel wire 11, on the front, the back, the left and the right of a coat. Moreover, the Heat Resistance of 10 is placed on the inner side of the coat, and pin 5 passes through cloth 1 to form a knot with the enamel wire 11. This cloth, on which there is a packaging cloth for packing and insulation, as well as for protecting the Heat Resistance and the enamel wire, measures a person's body temperature. This is shown in
(52)
Communicative signals are put in at both ends. When the frequency of communicative signals is very close to f, their resistance is close to zero, and the current can smoothly pass capacitance and inductance. On the contrary, when the distance between the frequency of communicative signals and f is very great, the resistance is very great, and it's hard for the current to pass capacitance and inductance, as well as the series resistance.
(53) In
(54) Example 2 is the detection done by a respiration detection belt. First of all, overlap two respiration bands, and combine the same ends N of both bands together, one of which is an elastic band A1 and the other is a non-elastic cloth of length L1. A conductive material like a Convex clasp M 1 is placed on one band, and four conductive wires a 1, a 2, a 3, a 4 are placed on the other band that is not elastic. When a user's stomach or chest becomes bigger while inhaling air, the elastic band A1 becomes longer, leading the conductive materials M 1 to move, but at this time, a 1, a 2, a 3, a 4 conductive wires remain unmoved, leading the Convex clasp M 1 to come to various contact with a 1, a 2, a 3, a 4 conductive wires, in response to the respiration. So the frequency and amplitude of the respiration that we measured, as
(55) An average electronic circuit commonly uses electronic modules with three pins, such as transistors, gates and so on, so there are three conductive regions. We can connect a conductive region and the transmission wires of a circuit on one side of the packaging cloth or the cloth for attire, while the other two conductive regions and the transmission wires come into contact on the opposite side of the packaging cloth or the cloth for attire, so as to avoid dangers of fusion due to overlapping. In addition, processors with 8 pins or 16 pins may use the method of “entrapping” the transmission wires, that is to say, pins, i.e. the conductive regions, pass through the cloth to hook up the transmission wires, then every transmission wire won't have the chance to contact another transmission wire that is connected with another pin, as illustrated in
(56) Additionally, it can also have standby transmission line 2′. When the transmission line 2 is cut off, the whole circuit can still be in operation as the conduction region 5 of electronic component 3 is connected with another transmission line 2′ simultaneously, as in
(57) Commonly-used transmission lines have multiple types, such as twin-lead wire, parallel multi-conductor, coaxial wire, ribbon line, single-core wire, multi-core and multiple strands etc. Many transmission lines have insulator outside of the conductor, such as Teflon, PVC or other polymer materials as insulator, as in
(58) As the invention is to sew electronic component 3 or transmission line 2 on the packaging cloth 1 or clothing cloth 1′, it will affect the output results whether the conductive region 5 of electronic component is connected with the transmission line 2 closely. Therefore, we use this method to generate pressure or tension sensor, i.e. the output value is varied as the variation of external pressure or tension when the conductive region of electronic component is connected with the transmission line 2, e.g. if the electronic components are resistors, capacitors, inductors, amplifiers, switches, thermistors, microphone and electrodes etc, the output value may have different results due to the closing degree of conductive region and transmission line 2, and the closing degree may produce variation as the changing of external pressure or tension. Therefore, it can be pressure or tension sensor.
(59) Additionally, to increase pressure or tension sensor value, we can add non-conductive yarns or materials between the conductive region of electronic component and transmission line to increase the sensing value of pressure or tension sensor. For above stated all kinds of methods, weaving, knitting, crocheting, knotting, stitching and other methods are used for sewing and pasting between the transmission line and cloth. The routing methods can be divided into straitening, bending, snake-like shape, above or below different cloth layers or the same cloth layer, and other methods.
(60) Finally, if the packaging cloth 1 or clothing cloth 1′ has integrated transmission line originally, it can be used as standby transmission line 2′. In one word, the electronic component and transmission line of the invention are added on the packaging cloth 1 or clothing cloth 1′ additionally. Therefore, when the electronic component 3 or transmission line 2 has failure, it is permitted to remove the electronic component 3 or transmission line 2 and replace them with new ones. It is unnecessary to discharge them completely and the user can make recovery independently.
(61) Additionally, to enhance the fixing reliability of electronic component, transmission line and cloth, it can glue again for fixing after the combination of transmission line electronic component, such as adhesive or heat shrink tubing. In this way, it enables the jointing of pins of electronic component and transmission line 2 or 4 more stable and has insulation at the same time.
(62) For the above methods, we use avometer, oscilloscopes and other electronic equipment to measure whether the electronic component is in good contact with the conductive region of transmission line. At the same time, it measures whether changes are produced under the effect of external force, thus to adjust the relations between the electronic component and transmission line or between the electronic component and another electronic component or between the two transmission lines, for example, shorten the distance between the two transmission lines to increase the force of two transmission line to the electronic component, or the cloth itself has elasticity, or add elastic material on the cloth, such as SBR, sponge and rubber etc. In this way, it enables the electronic component be fitter to the conductive region of transmission line. If the transmission line or the electronic component itself has elastic characteristics, it may generate better closing effect when the partial insulation layer eliminated transmission is jointed with the conductive region of conductive component, for example, the external insulation layer of transmission line is composed of elastic materials, On the other hand, when the conductive region of electronic component or the surface of transmission line is not smooth, it is also difficult to be separated for jointing of both, for example, the surface of conductive region of electronic component is in concave shape, concave structure is embedded when the transmission is jointed with the conductive region, which may lead to stable combination of the both.
(63) Another method of the invention is to use the heat melt adhesive film as the substrate, and at least one conductive region of electronic component or at least one transmission line is sewn, stuck or pasted on the heat melt adhesive film to form a circuit board. In the method of taking another heat melt adhesive film as the substrate, it is changed into fixing the heat melt adhesive film on the cloth for use as the substrate, and at least one electronic component or at least one transmission line is stuck or pasted on the heat melt adhesive film on the cloth to form a circuit board. Transmission lines on the heat melt adhesive film can be conductive fabric, conductive strips, stainless steel wire, conductive wire, silver fiber, polymer conductive material and rubber coated wire and enameled wire etc. If it has insulation layer, such as rubber coated wire, it can use chemical or mechanical method to eliminate the insulation layer on the connector of conductive region to contact the electronic component.
(64) As in
(65) In the cloth electronization method of the invention, a circuit routing layout of the circuit board can be printed on the heat melt adhesive film by heat transfer process and ink jetting method. Then sew, stick or paste the transmission lines on the heat melt adhesive film along the routing plan. Or it uses computerized sewing machine to sew a pre-arranged routing plan on to the heat melt adhesive film directly.
(66) First, print a circuit routing plan and electronic component placement drawing on the heat melt adhesive film. Then combine it with the cloth, and use heat gun to heat and use conductive cloth (other plain conductor or insulation line with degumming on contact point) as the transmission conductors of circuit. Finally, recombine it with the cloth (it can also be completed by sewing, sticking, or pasting) so that the heat melt adhesive film is placed between two layers of cloth and is not exposed to complete the complete stamping and routing, packaging process of electronic component which takes the heat melt adhesive film as circuit board.
(67) In another implementation example of the invention using heat melt adhesive film as the circuit board, the circuit board is a heat melt adhesive film with a transmission line. It is placed on the electronic component to enable the conductive region of electronic component contact with the conductive region of transmission line. Then, take heating and fixing to produce electronic board with contacting of electronic component and transmission line. During the process, a heat melt adhesive film without a transmission line can be added to increase the insulation of the electronic board. Additionally, if contact between the electronic component and transmission line is required, make the two installed heat melt adhesive films have transmission lines during the generation process of the circuit board. Place an electronic component between the two films to enable the conductive region of electronic component contact with the conductive region of transmission line. Finally, use heating and fixing to stick, paste, or sew the two heat melt adhesive films, so that the produced circuit board can enhance conduction intensity of transmission line and the electronic component.
(68) The method of fixing electronic component and transmission line on heat melt adhesive film (as in

(83) Adding the heat melt adhesive film to cloth is to heat the circuit board and fix it on packaging cloth. Then stick, sew and paste on clothing cloth or heat it to fix on the clothing cloth. Additionally, the circuit board can also be heated and fixed on the clothing cloth first and then stuck, sewn, or pasted on the packaging cloth or heated to be fixed on the packaging cloth. At the moment, the heat melt adhesive film is penetrated into the packaging cloth or clothing cloth to produce electronic packaging structure for cloth.
(84) Additionally, during the process to install heat melt adhesive film circuit board on cloth, a clamp can be used to apply force. Electronic component characteristics can be used to verify the connection between electronic component and transmission line, it shows that the package is not perfect. The package can also be tested by dripping water or color liquid on it. The characteristics of the electronic component can be measured to check the insulation of packaging, for example, if the capacitances before and after package are different, the package is not perfect.
(85) The invention takes the heat melt adhesive film circuit board to manufacture cloth electronic product. The method is to put manufactured the heat melt adhesive film circuit board on the packaging cloth first, and then cover oil separation paper on the circuit board to make the melt adhesive not stick on heating equipment. Then heat on one side of oil separation paper to melt the adhesive and stick the transmission lines on the packaging cloth together with the electronic component. After the oil separation paper is removed, place it on the pre-set packaging position of clothing cloth to take secondary recombination can also be completed by sewing, sticking, or gluing, pasting and other methods. Completed circuit board is located between the clothing cloth and packaging cloth. As the circuit board is covered by packaging cloth above, the circuit board will not be exposed to have a beautiful appearance. At the same time, the heat melt adhesive film is penetrated into the packaging cloth and clothing cloth after melting. After the packaging is completed, overall structure formed by the heat melt adhesive film and cloth is extremely firm (as in
(86) Another method of the invention which takes the adhesive circuit board to manufacture electronic product of cloth is to take simultaneous recombination and packaging of the heat melt adhesive film circuit, electronic component and cloth. The circuit board is the heat melt adhesive film with transmission line. Place the electronic component to enable the conductive region of electronic component contact with the conductive region of transmission line. Then place packaging cloth or clothing cloth above or below the circuit board to be heated and fixed, so that the electronic component is connected with the transmission line. At the same time, the heat melt adhesive film is permeated in packaging cloth or clothing cloth to produce packaging effect. Under the permission conditions of equipments (which requires computerized pattern machine and gang drilling machine), the method place the electronic component on the hot melt film with conductor and then place on corresponding position of clothing cloth. Then take heating recombination after packaging cloth is covered. All procedures are completed once (as in
(87) Furthermore, the method of invention to manufacture electronic product can also package individual component with conductive fabrics and then install it to other circuit. The circuit board includes one or minor electronic components. After it is heated and fixed with packaging cloth, an individual packaging component is produced. Then on clothing circuit, sew transmission line on individual packaging component to contact the clothing circuit with all individual components to produce a large scale circuit board.
(88) As the method is to manufacture circuit board on clothes, in practical application, if it needs to manufacture equal side circuit board with human body or overall large size circuit, the above stated method is still available. If semi-finished product size is large in manufacturing and packaging process, it will increase manufacturing difficulty and costs undoubtedly. It is manufactured via separating all parts to make the conductor cloth bond on the hot melt film. Then place all individual components on the film and cover cloth above and below. Take heating and recombination to make electronic components connect with circuit board composed of conductive fabrics, and package it between the two layers of cloth. Then use conductive sewing thread to penetrate the structure and make the packaging circuits of all electronic components connect with other circuits (as in
(89) In addition, invention can also use one cloth to complete the package. The packaging cloth is part of clothing cloth, i.e. the clothing cloth itself is packaging cloth.
(90) The method is to cooperate with traditional clothing production process, and it can also use clothing cloth as packaging cloth. Recombine adhesive circuit board initially at the clothing cloth pre-set position. Then fold the cloth reversely to enable the circuit board in the cloth. Then take secondary recombination, and it can also be completed by sewing, sticking or pasting methods, or it can place the adhesive circuit board on clothing cloth preset position after reverse folding. Then use only once heating and recombination to install the circuit board (as in
(91) The invention can achieve multilayer structure application. The circuit boards made of adhesive film have connection points and boards can be stacked such that the connection points can be overlapped to produce a multilayer circuit board structure textile. At the same time, insulation materials can also be placed between the upper layer and lower layer.
(92) Every layer of the circuit board made of heat melt adhesive film has at least one connection points and can be overlapped. It uses transmission line to connect the connection points of upper and lower layers to produce multilayer circuit board structure of textile. At the same time, insulation materials can also be placed between the upper layer and lower layer.
(93) The method can be used with conventional multilayer design of the electronics industry in practical application. An insulating plastic film can be placed between the upper and lower plates (which can also be replaced by fabrics, oil separation paper, heat melt adhesive film, glass fiber cloth). Previously introduced packaging technology is used to package circuit board. Then use transmission line to penetrate connection points of upper and lower plates and connect the upper and lower layers of circuits. Multilayer structure diagram is formed (as in
(94) The invention can manufacture multilayer plate with heat radiation structure. When multilayer plate is produced, as some power consumption of circuit structure is greater, sometimes, it may generate more heat in circuit. In order to prevent affecting normal operation of product, heat radiation structure can be added in the circuit structure with larger power consumption. Take the grounding circuit board structure in
(95) For part multilayer board manufactured by the invention, if the heat melt adhesive film produced circuit board requires electromagnetic shielding interference, a kind of conductive material can be set below, and it has an insulating material layer between the conductive material and circuit board. At the same time, it has a conductor sewing through the three layers to generate electromagnetic protection.
(96) Due to process limitation in traditional electronics industries, if it requires one or several conductors in the circuit board providing electromagnetic protection, it shall manufacture a piece of recombination layer with the same size of circuit board and add the layer on the board regardless of the actual area. As the invented cloth circuit board is manufactured by sewing soft conductive materials via sewing machine, it can use computerized embroidery machine to penetrate the upper layer conductive sewing thread at the packaging conductor position which requires electromagnetic shielding and sew intensively along the two sides of route to achieve electromagnetic protection structure of part multilayer board. (This principle is similar to multi-point grounding of conventional electronic circuit design. When this process is used in textile circuit board, the number of grounding point shall be far more than conventional electronic circuit boards). See
(97) The invention has different practical using methods for different types of electronic components. Currently, the use electronic component shapes have 4 classes: surface-mount class components, plug-in class components, horizontal pin transistor class components), vertical pin transistor class components. In specific application, conductive fabric can be taken as compressing point, and conductive point sewing thread can also be taken as compressing point to take packaging according to the packaging method introduced from
(98) Reinforcing method of compressing point in the invention can be connected with conductive region of electronic component via the heat melt adhesive film produced transmission line, and can add conductive adhesive or low temperature soldering tin. If low temperature soldering tin is used, first, heat the low temperature soldering tin and melt it on the conductive region of electronic component. Then heat and fix the electronic component with low temperature soldering tin and adhesive component, such as conductive fabric. The permeation of low temperature soldering tin is enlarged to strengthen the connection of transmission line and electronic component. Above low temperature soldering tin can also be melted with the connection of transmission line for the heat melt adhesive film, and heated and fixed with the electronic component, which has the same effect. If conductive adhesive is added, it can be added when the packaging cloth or clothing cloth is heated and fixed, so as to make the connection of transmission line and connective region of electronic component more effective.
(99) This method has higher requirement in the working condition of electronic component. It can add conductive adhesive or low temperature soldering tin in the conductive region of electronic component or at the transmission line pin when the pad of electronic component and circuit connection are extremely stable to stick or weld the conductive region of electronic component or pins firmly in the fabric circuit. First, add low temperature soldering tin in the conductive region of electronic component (or at the transmission line pin), and cover oil separation paper above and below. Heat the soldering tin and make the soldering tin melt permeate into the conductive cloth to weld the conductive region of electronic component firmly with the conductive cloth. Then recombine with the heat melt adhesive film (as in
