[0002] Flexible printed circuit boards (FPCs) are highly reliable, flexible printed circuit boards made with polyimide or polyester film as the substrate. They are characterized by high wiring density, light weight, thinness, and good bendability. Screens often require FPC mounting during manufacturing; however, effectively securing the screen during FPC mounting is often difficult, and existing processes cannot flexibly determine the mounting positions of various FPCs directly on the screen. This has become a major challenge. Therefore, a new technical solution is urgently needed to address these problems. Utility Model Content

[0003] The purpose of this invention is to provide a fixture for assisting in the reverse folding and flattening of FPCs, which can effectively improve the flexibility and accuracy of FPC mounting, in order to address the shortcomings of the existing technology.

The first surface has a concave receiving cavity and a first groove. The first groove is located on the side of the receiving cavity. The receiving cavity is used to receive and place the screen of the FPC to be flattened and effectively prevents the screen from moving. The first groove is used to assist in picking up and placing the screen. A folding positioning plate is movably disposed on the surface of the sliding portion. In a first state, the folding positioning plate covers the receiving cavity and is parallel and tightly attached to the first surface. The folding positioning plate has a positioning notch that corresponds to both the receiving cavity and the first surface.

[0006] As an improvement of the auxiliary anti-folding and flattening fixture described in this utility model, the first surface has a concave groove spaced apart from the receiving cavity, the bottom of the sliding part is slidably disposed in the groove, and the sliding part has a pressing arm extending into the receiving cavity.

[0007] As an improvement of the auxiliary anti-folding and flattening fixture described in this utility model, the first surface has an outwardly protruding slide rail spaced apart from the receiving cavity, the bottom of the sliding part is slidably disposed on the slide rail, and the sliding part has a clamping arm extending into the receiving cavity.

[0008] As an improvement to the auxiliary folding and flattening fixture described in this utility model, the folding positioning plate is rotatably mounted on the sliding part by a rotating component, and the folding positioning plate can be circumferentially flipped by the rotating component.

[0009] As an improvement to the auxiliary anti-folding and flattening fixture described in this utility model, one or more limiting and pressing elements are provided on the inner side wall of the receiving cavity.

[0010] As an improvement to the auxiliary anti-folding and flattening fixture described in this utility model, one end of the limiting and clamping member is fixedly connected to the inner wall of the receiving cavity.

[0011] As an improvement of the auxiliary anti-folding and flattening fixture described in this utility model, one end of the limiting and pressing member extends horizontally from the receiving cavity to the side of the supporting part.

[0012] As an improvement of the auxiliary anti-folding and flattening fixture described in this utility model, the side of the supporting part is provided with a flipping part. In the first state, the flipping part corresponds to the positioning notch. The overlapping part of the positioning notch and the receiving cavity is the area to be pasted on the screen. The flipping part is used to press the FPC onto the area defined by the positioning notch.

[0013] As an improvement of the auxiliary folding and flattening fixture described in this utility model, the flipping part includes a rotating shaft and a V-shaped flipping member. The V-shaped flipping member is rotatably mounted on the side of the supporting part through the rotating shaft.

[0014] As an improvement to the auxiliary folding and flattening fixture described in this utility model, the folding positioning plate is fixed to the first surface by a fixing member in the first state, and the fixing member and the first groove are disposed opposite to or offset from each other on the first surface.

[0015] As an improvement to the auxiliary anti-folding and flattening fixture described in this utility model, the fixing element is a magnetic element.

[0016] The beneficial effects of this utility model are as follows: This utility model includes a support portion and a sliding portion slidably mounted on the first surface of the support portion. The sliding portion is used to slide on the first surface to flexibly adjust the positioning position as needed. The first surface has a concave receiving cavity and a first groove. The first groove is located on the side of the receiving cavity. The receiving cavity is used to receive and place the screen to be flattened on the FPC and effectively prevents the screen from moving. The first groove is used to assist in picking up and placing the screen. When the screen is placed in the receiving cavity and the FPC is not flattened on the screen, it is the first state set by the fixture. Because a folding positioning plate is movably provided on the surface of the sliding portion, In its first state, the folding positioning plate covers the receiving cavity and is parallel and tightly attached to the first surface. The folding positioning plate can be flexibly matched with various FPCs for various screens through the adjustment of the sliding part. The folding positioning plate has positioning notches that correspond to the receiving cavity and the first surface. By folding the FPC into the positioning notches, the FPC can be efficiently flattened onto the screen, thereby completing the perfect mounting of the FPC and the screen. Furthermore, with the cooperation of the sliding part, the folding positioning plate, the positioning notches, the receiving cavity, and the first surface, the fixture has better mounting flexibility, adaptability, and accuracy for different FPCs.

[0030] The following is in conjunction with the appendix Figures 1-9 The present invention will be further described in detail with reference to specific embodiments, but this is not intended to limit the present invention.

[0031] Example 1

[0032] A jig to assist in folding and flattening, see [link to jig]. Figure 1The device includes a support portion 1 and a sliding portion 2 slidably mounted on a first surface 1a of the support portion 1. The first surface 1a has a concave receiving cavity 10 and a first groove 11. The first groove 11 is located on the side of the receiving cavity 10. A folding positioning plate 3 is movably disposed on the surface of the sliding portion 2. In the first state, the folding positioning plate 3 covers the receiving cavity 10 and is parallel and tightly attached to the first surface 1a. The folding positioning plate 3 has a positioning notch 3a that corresponds to both the receiving cavity 10 and the first surface 1a.

[0033] The receiving cavity 10 is used to receive and place the screen 8 to be flattened by the FPC and effectively prevents the screen 8 from moving. The first groove 11 is used to assist in picking up and placing the screen 8. When the screen 8 is placed in the receiving cavity 10 and the FPC is not flattened to the screen 8, it is the first state set by the fixture. Since the sliding part 2 is movably provided with the folding positioning plate 3, the folding positioning plate 3 covers the receiving cavity 10 and is parallel and tightly attached to the first surface 1a in the first state. The folding positioning plate 3 can be flexibly matched with various FPCs of various screens by adjusting the left and right sides of the sliding part 2.

[0034] Furthermore, by placing the screen 8 in the receiving cavity 10, and then folding the FPC back into the positioning notch 3a, the FPC can be efficiently and flattened onto the screen 8. (See [reference needed]). Figure 9 This completes the proper mounting of the FPC and screen 8.

[0035] Preferably, the first surface 1a has a concave groove 12 spaced apart from the receiving cavity 10. The groove 12 can be formed in the length direction or the width direction of the first surface 1a. The bottom of the sliding part 2 is slidably disposed in the groove 12. A part of the sliding part 2 can be slidably disposed on the first surface 1a. Furthermore, the sliding part 2 has a clamping arm 4 extending into the receiving cavity 10. The clamping arm 4 can further improve the fixing effect of the screen 8 when the folding positioning plate 3 presses the clamping arm 4 against the screen 8. The clamping arm 4 can be made of silicone material, thereby effectively preventing damage to the screen 8.

[0036] Preferred, see Figures 2-3 The folding positioning plate 3 is rotatably mounted on the sliding part 2 via the rotating member 5. The rotating shaft of the rotating member 5 is rotatably inserted into the side of the sliding part 2. The folding positioning plate 3 is mounted on the upper surface of the rotating member 5. A groove can be opened on one side of the folding positioning plate 3 so that the protrusion on the upper surface of the rotating member 5 can be inserted into the groove to achieve stable assembly of the two. The upper surface of the rotating member 5 is slightly higher than the top of the sliding part 2. The rotating member 5 can drive the folding positioning plate 3 to press from above the receiving cavity 10 onto the receiving cavity 10.

[0037] Preferred, see Figure 5 The inner wall of the receiving cavity 10 is provided with one or more limiting clamping elements 14.

[0038] One end of the limiting clamping member 14 is fixedly connected to the inner wall of the receiving cavity 10, or one end of the limiting clamping member 14 extends horizontally from the receiving cavity 10 to the side of the supporting part 1, so that the limiting clamping member 14 can press against the side of the screen 8. The limiting clamping member 14 can further improve the fixing effect of the screen 8 and prevent the screen 8 from moving and causing inaccurate FPC bonding.

[0039] Preferred, see Figures 6-7 The side of the supporting part 1 is provided with a flipping part 6, which corresponds to the positioning notch 3a in the first state.

[0040] The flipping part 6 includes a rotating shaft 61 and a V-shaped flipping member 62. The V-shaped flipping member 62 is rotatably mounted on the side of the support part 1 via the rotating shaft 61. In the first state, the V-shaped flipping member 62 corresponds to the positioning notch 3a. The rotating shaft 61 can rotate circumferentially on the side of the support part 1, thereby driving the V-shaped flipping member 62 to press the FPC onto the area defined by the positioning notch 3a, and the FPC moves from... Figure 8 The unfolded state is folded back to obtain Figure 9 The structure allows the FPC to be precisely attached to the designated area of ​​the screen 8. The overlapping portion of the positioning notch 3a and the receiving cavity 10 is the area to be attached to the screen 8, and the overlapping portion of the positioning notch 3a and the first surface 1a is the receiving area of ​​the FPC lead-out end.

[0041] Preferably, in the first state, the folding positioning plate 3 is fixed to the first surface 1a by the fixing member 7. The fixing member 7 and the first groove 11 are disposed opposite to or staggered on the first surface 1a. The fixing member 7 can be a magnetic member. The fixing member 7 can lock the folding positioning plate 3 to the first surface 1a, thereby improving the accuracy of the FPC being attached to the designated area of ​​the screen 8.
