Description

Technical Field

[0001] The present application relates to the technical field of FPC processing devices, and in particular to an FPC auxiliary film positioning mechanism. Background Art

[0002] With the continuous development and progress of science and technology, the requirements for circuit boards are getting higher and higher, especially for digital products that pursue convenience and lightness. Flexible circuit boards with the advantages of flexibility, ultra-thinness and light weight have been greatly developed and applied in the field of electronics.

[0003] FPC is a highly reliable and flexible printed circuit made of polyimide or polyester film. Since FPC is a flexible circuit board, it is relatively soft as a whole. When it is used, it is usually necessary to connect electrical appliances in some areas, so it is necessary to pre-paste PI film on some areas for reinforcement to achieve local support.

[0004] Regarding the above-mentioned related technologies, when workers reinforce FPC, they usually place the FPC board directly on the work surface and then bond the PI film to the FPC board. Due to the lack of corresponding positioning fixtures, the FPC board is prone to slide during the bonding process, which in turn affects the bonding of the PI film, so there is room for improvement. Utility Model Content

[0005] In order to facilitate the staff to bond the PI film to the FPC board, the present application provides an FPC auxiliary film positioning mechanism.

[0006] The FPC auxiliary film positioning mechanism provided in this application adopts the following technical solution:

[0007] An FPC auxiliary film positioning mechanism comprises a base plate, an auxiliary plate and a pressure plate, wherein both the auxiliary plate and the pressure plate can be rotatably connected to the base plate, and the auxiliary plate is located between the pressure plate and the base plate; a plurality of positioning pins are arranged on one side of the base plate, and the positioning pins face the auxiliary plate and are used to position the FPC board; both the auxiliary plate and the pressure plate are provided with clearance holes for the positioning pins to pass through, and the pressure plate is used to press the PI film tightly onto the FPC board.

[0008] By adopting the above technical solution, the positioning mechanism includes three layers, which can be flipped over each other. When in use, the auxiliary plate is attached to the bottom plate, and then the FPC board is pre-placed on the top of the auxiliary plate, and then the PI reinforcement strips prepared externally are sequentially pasted in the corresponding areas with positioning pins; there are corresponding clearance holes on the auxiliary plate, and the positioning pins pass through the clearance holes and the FPC board to achieve penetration and positioning. When all the PI reinforcement strips are pasted, the pressure plate is abutted against the bottom plate of the auxiliary plate to further crimp the PI reinforcement strips, so that the PI reinforcement strips and the FPC board fit more closely, and finally the pressure plate is opened, and then the auxiliary plates are uniformly flipped to the left, and the FPC board is removed from the auxiliary plate. Under the positioning action of the positioning mechanism, the possibility of the FPC board position shifting is reduced, which makes it convenient for the staff to bond the PI film to the FPC board.

[0009] Preferably, a side of the bottom plate away from the pressing plate is provided with an anti-slip layer.

[0010] By adopting the above technical solution, the anti-slip layer has a good anti-slip coefficient, which can increase the static friction between the base plate and the workbench when they are in contact with each other, and reduce the possibility of the base plate slipping on the workbench during the bonding process.

[0011] Preferably, the end of the positioning needle is arranged in an arc shape.

[0012] By adopting the above technical solution and setting the arc at the end of the positioning needle, the pressure on the staff when touching the positioning needle can be reduced, and the comfort of the staff when touching the positioning needle can be improved.

[0013] Preferably, the base plate, the auxiliary plate and the pressing plate are all made of plastic material.

[0014] By adopting the above technical solution, the positioning mechanism made of plastic material has the characteristics of light weight, which makes it convenient to carry the positioning mechanism and can also reduce the production cost.

[0015] Preferably, one side of the edge of the pressing plate and the auxiliary plate is extended with a gripping plate, and the gripping plate is used for people to grip.

[0016] By adopting the above technical solution, since the length and width of the pressing plate, the auxiliary plate and the bottom plate are basically the same, after the pressing plate is pressed on the auxiliary plate, the pressing plate, the auxiliary plate and the bottom plate are in a close fit state, and it is not easy to apply external force to the pressing plate and the auxiliary plate and control the rotation of the two. Now, by adding a gripping plate, the gripping plate can be used as a force point for the staff to grasp, so that it is convenient to apply force to the pressing plate and the auxiliary plate.

[0017] Preferably, a sink groove is provided on the bottom plate, the depth of the sink groove is less than the length of the positioning pin, one end of the positioning pin is located in the sink groove, and the end of the positioning pin located in the sink groove is connected to an anti-bending member.

[0018] By adopting the above technical solution, the sink groove provides a corresponding installation space for the positioning pin, and the anti-bending member can support and strengthen the positioning pin, thereby reducing the possibility of bending of the positioning pin.

[0019] Preferably, a first elastic layer is provided on a side of the auxiliary plate facing the pressing plate, and the first elastic layer is made of an elastic material.

[0020] By adopting the above technical solution, the side of the auxiliary plate facing the pressure plate is used to support the FPC board. The first elastic layer has good elasticity. When the pressure plate is pressed on the auxiliary plate, the first elastic layer can play a good buffering and protective effect, reducing damage to the FPC board.

[0021] Preferably, a second elastic layer is provided on a side of the pressing plate facing the auxiliary plate, and the second elastic layer is made of an elastic material.

[0022] By adopting the above technical solution, similarly, the second elastic layer on the pressing plate can protect the FPC board and increase the elastic force when the pressing plate and the FPC board are in contact with each other.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] (1) By setting up the mutually flipped bottom plate, auxiliary plate and pressure plate, the FPC board is placed on the auxiliary plate, and then the PI reinforcement strips prepared outside are pasted in the corresponding areas with positioning pins in turn. When all the PI reinforcement strips are pasted, the pressure plate is abutted against the bottom plate of the auxiliary plate to further press the PI reinforcement strips so that the PI reinforcement strips and the FPC board fit more tightly. Finally, open the pressure plate and auxiliary plate in turn, remove the FPC board with the PI reinforcement strips bonded, and proceed to process the next FPC board.

[0025] (2) By setting the end of the positioning pin to be circular arc, the pressure on the workers when they touch the positioning pin during the production process can be reduced.

[0026] (3) By providing a gripping plate, the gripping plate can be used as a force point for workers to grasp, making it convenient for workers to apply force to the pressure plate and the auxiliary plate. BRIEF DESCRIPTION OF THE DRAWINGS

In the absence of conflict, those skilled in the art may combine and combine different embodiments or examples and features of different embodiments or examples shown in the present application.

[0037] The present application embodiment discloses an FPC auxiliary film positioning mechanism. Figure 1 and Figure 2The positioning mechanism includes a base plate 1, an auxiliary plate 2 and a pressure plate 3. The base plate 1, the auxiliary plate 2 and the pressure plate 3 are all rectangular in shape, and the length and width of the three are equal. The auxiliary plate 2 is located between the pressure plate 3 and the base plate 1. The auxiliary plate 2 and the pressure plate 3 can be rotatably connected to the base plate 1, and the rotation axis of the auxiliary plate 2 and the pressure plate 3 is the same, so that the auxiliary plate 2, the pressure plate 3 and the base plate 1 can be flipped over each other. Among them, the base plate 1, the auxiliary plate 2 and the pressure plate 3 are all made of plastic materials, and the plastics include PP, PS or PC. The positioning mechanism made of plastic material has the characteristics of light weight, which is convenient for carrying the positioning mechanism and can also reduce the production cost.

[0038] Specifically, the side of the bottom plate 1 away from the pressing plate 3 is fixedly connected with an anti-skid layer (not shown in the figure), and the anti-skid layer is made of anti-skid material. When the entire positioning mechanism is placed on the workbench, the bottom plate 1 will fit and contact with the workbench. The anti-skid layer has a good anti-skid coefficient, which can increase the static friction when the bottom plate 1 and the workbench are in contact, and reduce the possibility of the bottom plate 1 slipping on the workbench during the bonding process. A plurality of positioning pins 4 are fixedly connected to the surface of the bottom plate 1 facing the auxiliary plate 2. The positioning pins 4 are vertically arranged, and one end faces the auxiliary plate 2. Each positioning pin 4 is distributed on the surface of the bottom plate 1 at intervals, and the positioning pins 4 are used to position the FPC board. The positioning pin 4 has a certain thickness, and the positioning pin 4 is arranged in an arc at one end away from the bottom plate 1. The positioning pin 4 with a circular end can increase the contact area between the staff and the positioning pin 4, reduce the pressure on the staff when contacting the positioning pin 4, and improve the comfort of the staff when contacting the positioning pin 4. A through-hole 5 is provided on the auxiliary plate 2 and the pressing plate 3, and the hole 5 is used for the positioning pin 4 to pass through. The auxiliary plate 2 serves as a supporting plane for placing the FPC board; the pressing plate 3 is used to press the PI film onto the FPC board.

[0039] When in use, the auxiliary plate 2 is attached to the bottom plate 1, and then the FPC board is pre-placed on the top of the auxiliary plate 2, and then the PI reinforcement strips prepared externally are sequentially attached to the corresponding areas with positioning pins 4; there are corresponding clearance holes 5 on the auxiliary plate 2, and the positioning pins 4 pass through the clearance holes 5 and the FPC board to achieve penetration and positioning. When all the PI reinforcement strips are attached, the pressing plate 3 is abutted against the bottom plate 1 of the auxiliary plate 2 to further press the PI reinforcement strips, so that the PI reinforcement strips and the FPC board fit more closely, and finally the pressing plate 3 is opened, and then the auxiliary plates 2 are uniformly flipped to the left, and the FPC board is removed from the auxiliary plate 2. Under the positioning action of the positioning mechanism, the possibility of the FPC board position shifting is reduced, which makes it convenient for the staff to bond the PI film to the FPC board.

[0040] According to some embodiments of the present application, optionally, please refer to Figure 2 and Figure 3. A plurality of recessed grooves 6 are provided on the bottom plate 1, and the recessed grooves 6 provide corresponding installation spaces for the positioning pins 4, and each positioning pin 4 is installed in each recessed groove 6. The notch of the recessed groove 6 is circular, and the depth of the recessed groove 6 is less than the length of the positioning pin 4. One end of the positioning pin 4 is located in the recessed groove 6, and the end of the positioning pin 4 located in the recessed groove 6 is connected to an anti-bending member 7. The anti-bending member 7 is fixedly connected in the recessed groove 6. The anti-bending member 7 is block-shaped and has a through hole in the middle. The positioning pin 4 passes through the through hole and is welded to the anti-bending member 7. The anti-bending member 7 can support and strengthen the positioning pin 4 axially, thereby reducing the possibility of bending of the positioning pin 4.

[0041] According to some embodiments of the present application, optionally, please refer to Figure 4 . A gripping plate 8 is extended and connected to one side of the edge of the pressing plate 3 and the auxiliary plate 2, and the gripping plate 8 is used for the staff to grasp. Since the length and width of the pressing plate 3, the auxiliary plate 2 and the bottom plate 1 are basically the same, after the pressing plate 3 is pressed on the auxiliary plate 2, the pressing plate 3, the auxiliary plate 2 and the bottom plate 1 are in a fitted state, and it is not easy to apply external force to the pressing plate 3 and the auxiliary plate 2 and control the rotation of the two. Now, by adding the gripping plate 8, the gripping plate 8 can be used as a force point for the staff to grasp, so that it is convenient to apply force to the pressing plate 3 and the auxiliary plate 2.

[0042] According to some embodiments of the present application, optionally, a first elastic layer (not shown in the figure) is fixedly connected to one side of the auxiliary plate 2 facing the pressure plate 3, and the first elastic layer is made of an elastic material, and the elastic material includes but is not limited to rubber and sponge.

[0043] Similarly, a second elastic layer (not shown in the figure) is fixedly connected to the side of the pressing plate 3 facing the auxiliary plate 2, and the second elastic layer is also made of elastic material. Both the first elastic layer and the second elastic layer have good elasticity. When the pressing plate 3 is pressed on the auxiliary plate 2, the first elastic layer and the second elastic layer can play a good buffering and protective effect, reducing the damage to the FPC board.

[0044] The implementation principle of the FPC auxiliary film positioning mechanism of the embodiment of the present application is as follows: when in use, the auxiliary plate 2 is attached to the bottom plate 1, and then the FPC board is pre-placed on the top of the auxiliary plate 2, and then the PI reinforcement strip prepared externally is sequentially attached to the corresponding area with the positioning pin 4; there are corresponding clearance holes 5 on the auxiliary plate 2, and the positioning pin 4 passes through the clearance holes 5 and the FPC board to achieve penetration and positioning. When all the PI reinforcement strips are attached, the pressing plate 3 is abutted against the bottom plate 1 of the auxiliary plate 2 to further press the PI reinforcement strips, so that the PI reinforcement strips and the FPC board are more closely attached, and finally the pressing plate 3 is opened, and then the auxiliary plate 2 is uniformly flipped to the left, and the FPC board is removed from the auxiliary plate 2.

[0045] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
