The variable volume body comes into contact with the forming film positioned in the mold in accordance with a volume change of the variable volume body. The variable volume body presses the forming film so that the forming film is mold in a 3D shape.

[0050] Hereinafter, the present disclosure will be described with reference to the accompanying drawings. However, the present disclosure may be embodied in various forms and is not limited to the embodiment described in the present specification. In the drawings, parts irrelevant to the description will be omitted for a clear description of the present disclosure.

Additionally, when it is mentioned that a portion “includes” a component, it means that the portion does not exclude but further includes other components unless there is a special opposite mention.

[0052] Terms used in the present specification are provided for description of only specific embodiments of the present invention, and not intended to be limiting. An expression of a singular form includes the expression of plural form thereof unless otherwise explicitly mentioned in the context. In the present specification, it should be understood that the term “include” or “comprise” and the like is intended to specify characteristics, numbers, steps, operations, components, parts or any combination thereof which are mentioned in the specification, and intended not to previously exclude the possibility of existence or addition of at least one another characteristics, numbers, steps, operations, components, parts or any combination thereof.

[0053] Hereinafter, the embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0054] FIG. 1 is a front view of a manufacturing device according to an embodiment of the present invention. FIG. 2 is a plan view of the manufacturing device according to the embodiment of the present invention. FIG. 3 is a right-side view of the manufacturing device according to the embodiment of the present invention. FIG. 4 is a front view of a press head unit 100 according to the embodiment of the present invention. FIG. 5 shows a plan view and a right-side view of the press head unit 100 according to the embodiment of the present invention. Here, the plan view of the press head unit 100 is shown in (a) of FIG. 5, and the right side-view of the press head unit 100 is shown in (b) of FIG. 5.

[0055] As shown in FIGS. 1 to 5, the manufacturing device according to the embodiment of the present invention includes: a mold 220 for molding a forming film; a press head unit 100 which is positioned to correspond to the mold 220 and has a variable spaced distance from the mold 220; and a variable volume body 210 which is coupled to the press head unit 100 and has elasticity so that a volume thereof is variable due to gas introduction and discharge by the press head unit 100. The variable volume body 210 comes into contact with the forming film positioned in the mold 220 in accordance with a volume change of the variable volume body 210. The variable volume body presses the forming film so that the forming film is mold in a 3D shape.

[0056] That is, in the case of most conventional general films, flat (flat plate-shaped) films have been mainly used, and press devices for processing such flat films have been molding the film by applying pressure in only one direction.

[0057] When using such conventional press devices, there is a problem that the 3D-shaped film cannot be molded. This is because the pressure surface of the press device is moved only in the up-and-down or the right-and-left direction so that the curved surface cannot be pressed. Particularly, it is not possible to mold such that the forming film for protecting the display of a mobile phone with a bent end, which has been widely being used recently, has a certain curvature.

[0058] However, in the device for manufacturing a 3D forming film, the separate variable volume body 210 is additionally attached to the end of the press head unit 100, which comes into contact with the mold 220, and gas is controlled to be introduced into or discharged from the variable volume body 210. Accordingly, as with a conventional press device, it is possible not only to manufacture a flat film by pressing the flat upper portion of the mold 220 but also to perform press processing on the 3D forming film with a bend end by the variable volume body 210 pressing the outside of the mold with a bent end.

[0059] A mold having separate curvatures according to the appearance of various mobile phones or displays is designed, and, regardless of the curvature of the bent end of the mold, the variable volume body 210 can press the mold while expanding. Therefore, the device for manufacturing a 3D forming film according to the embodiment of the present invention has an advantage of being freely used regardless of the mold or a target product.

[0060] A detailed configuration for manufacturing a 3D forming film according to the expansion and pressing of the variable volume body 210 will be described. The configuration further includes a height adjuster which is connected to one side of the mold 220 or the press head unit 100 and adjusts an up and down position of the mold 220 or the press head unit 100. It is possible to easily control the molding of the forming film in accordance with the operation of the height adjuster.

[0061] That is, the height adjuster adjusts only the up and down position of any one of the mold 220 or the press head unit 100 and then applies pressure to the forming film, or adjusts simultaneously the positions of both the mold 220 and the press head unit 100 and then applies pressure to the forming film. There is no need to be limited to any one of them.

[0062] In addition, the press head unit 100 may include a gas controller 120 which introduces gas received from the outside into the variable volume body 210 or discharges the gas inside the variable volume body 210. Here, the press head unit 100 may further include: a press frame 160;

[0063] an up-and-down moving body 140 which is coupled to the press frame 160 and performs an up-and-down linear motion; a press motor 150 which is coupled to the up-and-down moving body 140; a screw shaft 130 which has an end thereof coupled to the press motor 150 and the other end thereof coupled to an upper portion of the gas controller 120 and is screw-coupled to the press frame 160 to perform a rotational motion and an up-and-down linear motion; and a press head 110 of which an upper portion thereof is coupled to the gas controller 120 and of which a lower portion thereof is coupled to the variable volume body 210.

[0064] Therefore, it is more preferable that the variable volume body 210 is formed such that it expands partially by introducing a portion of the gas before contacting the forming film and then contacts the forming film, and expands by introducing the remaining gas after contacting the forming film so that the mold and a curved portion of the forming film are pressed and 3D-molded.

[0065] The manufacturing device of the embodiment of the present invention may include a device frame part 920 which forms the outermost shape of the manufacturing device of the present invention. The press frame 160 may be coupled with the device frame unit 920 such that it is located upwardly from the center of the device frame unit 920. The press frame 160 may include a first guide shaft 161, a second guide shaft 162, a third guide shaft 163, and a fourth guide shaft 164 which are coupled with the up-and-down moving body 140 moving in the up and down direction and guide the up-and-down moving body 140. Here, the first to fourth guide shafts 161 to 164 may have a rod shape, but are not limited thereto.

[0066] The gas controller 120 is connected to a pump formed outside the manufacturing device according to the embodiment of the present invention, and the pump may press and supply gas to the gas controller 120 or provide a gas suction force to the gas controller 120. Here, the gas may be air, but is not limited thereto. Further, the gas controller 120 may include a gas control valve. When the pump presses and supplies gas to the gas controller 120, the gas control valve is opened and gas is introduced into the variable volume body 210, thereby increasing the volume of the variable volume body 210. Here, when the variable volume body 210 is changed to a preset volume, the gas control valve is closed to maintain the shape of the variable volume body 210 having the increased volume. Also, when the pump provides a gas suction force to the gas controller 120, the gas control valve is opened and the gas is discharged to the pump, so that the volume of the variable volume body 210 may be reduced.

[0067] The press head unit 100 may further include a screw guide body 165 that is fixedly coupled to the press frame 160 and has a female screw thread formed on an inner surface thereof. Here, the screw shaft 130 may have a male screw thread formed on the outer surface thereof, and the screw shaft 130 and the screw guide body 165 may be coupled. Also, the screw shaft 130 performs an up-and-down linear motion according to the rotation direction of the screw shaft 130 coupled with the press motor 150, and accordingly, the press motor 150 performs an up-and-down linear motion, so that the up-and-down moving body 140 coupled with the press motor 150 may perform an up-and-down linear motion. Also, according to the up-and-down linear motion of the screw shaft 130, the gas controller 120 and the press head 110 may perform an up-and-down linear motion.

[0068] The press head unit 100 may include a press head guide shaft 170 which is coupled to the press head 110 and guides the up-and-down linear motion of the press head 110. Accordingly, even when the screw shaft 130 rotates, the press head 110 and the gas controller 120 do not rotate and the press head 110 can perform an up-and-down linear motion along the press head guide shaft 170. Here, the other end of the screw shaft 130 coupled with the gas controller 120 has an outer surface of a curved surface without a male screw thread formed thereon, and the other end of the screw shaft 130 can perform a free rotation with respect to the gas controller 120.

[0069] The mold 220 is formed in a shape corresponding to the molding shape of the forming film, and may be formed of metal. The mold 220 is installed to be coupled to the press frame 160, and may be positioned to be spaced apart from the press head 110 under the press head 110.

[0070] The variable volume body 210 may be formed of a material having elasticity, and specifically, may be formed of natural rubber or a polymer material. In the embodiment of the present invention, it is described that the variable volume body 210 is formed of the above-mentioned material, but is not limited thereto, and may be formed of another material having elasticity. The variable volume body 210 having an increased volume may have a rectangular parallelepiped shape having a curved edge. Accordingly, a press process in which a bottom side of the variable volume body 210 having an increased volume comes into contact with the forming film and the variable volume body 210 presses the forming film on the mold 220 by the descent of the press head 110.

[0071] FIG. 6 shows a plan view and a front view of a clamp unit 800 according to the embodiment of the present invention. Here, the plan view of the clamp unit 800 is shown in (a) of FIG. 6, and the front view of the clamp unit 800 is shown in (b) of FIG. 6. As shown in FIG. 6, the manufacturing device according to the embodiment of the present invention may further include the clamp unit 800 which is installed adjacent to the mold 220 and fixes and supports the forming film when the forming film is positioned on the mold 220. The clamp unit 800 may include a tong-shaped clamp 810 which grips and fixes the forming film when the forming film is positioned on the mold 220, a clamp support 820 which is coupled to the clamp 810 and supports the clamp 810, a clamp screw shaft 830 which has a male screw thread formed on the outer surface thereof and is screw-coupled to the clamp support 820 having a female screw thread, a clamp motor 840 which is coupled with the clamp screw shaft 830 and performs a rotary motion, so that the clamp support 820 performs a left and right linear motion. The clamp motor 840 may be fixedly supported by being coupled with the device frame unit 920. Here, when the variable volume body 210 descends and comes into contact with the forming film on the mold 220 and then the forming film starts to be fixed by the variable volume body 210 and the mold 220, the clamp 810 may release the gripping of the forming film. Also, the clamp unit 800 may include a clamp sensor 850. The clamp sensor 850 may sense the position of the clamp 810. Accordingly, the position of the clamp 810 may be changed according to the position of the variable volume body 210. At least one clamp unit 800 may be formed.

[0072] Outside the manufacturing device according to the embodiment of the present invention, the forming film may be formed by punching a raw material film.
