[0002] Flexible printed circuit boards (FPCBs) are printed circuit boards made using flexible insulating substrates. They have many advantages that rigid FPCBs do not have, such as light weight, thinness, good flexibility, and high wiring density.

[0003] Flexible circuit boards (PCBs) are highly flexible, allowing them to be bent, rolled, and folded freely. They are suitable for applications with limited internal space, significantly reducing the size and weight of electronic devices. As a result, they hold an irreplaceable position in drones and aircraft data recorders. However, when processing PCBs, fixtures are required for positioning. Existing fixtures are inconvenient to use and have poor clamping effect, making them prone to falling off during processing and affecting the final result. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1.

Then, through the connection between the clockwise threaded rod and the connecting block, and the connection between the counterclockwise threaded rod and the connecting block, the thread grooves on the surfaces of the clockwise and counterclockwise threaded rods turn in opposite directions, thereby causing the connecting blocks on their surfaces to move towards each other. Then, through the connection between the adjusting plate and the connecting block, and the connection between the adjusting plate and the protective shell, the two sets of adjusting plates move towards each other, changing the working distance between the two sets of protective shells, thus achieving the effect of clamping irregular flexible circuit boards.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 One embodiment provided by this utility model:

[0023] A fixture for processing flexible printed circuit boards (FPCBs) includes a processing platform 1 for processing FPCBs. An adjusting plate 2 is provided on the surface of the processing platform 1, connecting a protective housing 21, a cylinder 22, and a connecting block 35. The protective housing 21 is fixedly connected to the surface of the adjusting plate 2 for clamping the FPCB. The cylinder 22 is fixedly connected to the surface of the adjusting plate 2 for moving a rack plate 24. A connecting rod 23 is movably connected to the surface of the cylinder 22 for connecting the rack plate 24. The end of the connecting rod 23 away from the cylinder 22 is fixedly connected to the rack plate 24 for driving a first gear 27 to rotate. A guide block 25 is movably connected inside the protective housing 21 for guiding the movement of the rack plate 24. A first fixed shaft 26 is fixedly connected inside the adjusting plate 2 for rotating the first gear 27. The first gear 27 is meshed with the surface of the rack plate 24 for driving a second gear 29 to rotate. A second fixed shaft 28 is fixedly connected inside the adjusting plate 2 for rotating the second gear 29. The second gear 29 is meshed with the surface of the first gear 27 for driving a second gear 29 to rotate. The connecting rod 210 rotates, and the surface of the second gear 29 is fixedly connected to the connecting rod 210, which is used to drive the clamping block 212 to rotate and clamp the flexible circuit board. The surface of the connecting rod 210 is fixedly connected to the fixed threaded rod 211, which is used to connect the clamping block 212. The surface of the fixed threaded rod 211 is threadedly fitted with the clamping block 212, which is used to clamp the flexible circuit board. The surface of the processing platform 1 is provided with an adjustment groove 3, which is used to connect the clockwise threaded rod 32 and the counterclockwise threaded rod 34. The surface of the processing platform 1 is rotatably connected to the adjustment handle 3. 1. A clockwise threaded rod 32 is fixedly connected to the surface of the adjusting handle 31 to drive the connecting block 35 to move. A limit rod 33 is fixedly connected to the end of the clockwise threaded rod 32 away from the adjusting handle 31 to limit the movement position of the connecting block 35. A counterclockwise threaded rod 34 is fixedly connected to the end of the limit rod 33 away from the clockwise threaded rod 32 to drive the connecting block 35 to move. The connecting block 35 is threadedly sleeved on the surface of the clockwise threaded rod 32 to drive the adjusting plate 2 to move.

[0024] Furthermore, the adjusting plates 2 are symmetrically distributed in two sets on the surface of the processing platform 1. The connecting rod 23 is movably connected to the inside of the protective shell 21 through the cylinder 22. The rack plate 24 is movably connected to the inside of the protective shell 21 through the connecting rod 23. When the cylinder 22 is activated, it drives the connecting rod 23 to move, thereby driving the rack plate 24 to move inside the protective shell 21.

[0025] Furthermore, the first fixed shaft 26 is symmetrically distributed in two sets inside the protective shell 21, and the first gear 27 is symmetrically distributed in two sets on the surface of the first fixed shaft 26. The first gear 27 is rotatably connected to the surface of the first fixed shaft 26 through the rack plate 24. The movement of the rack plate 24 drives the first gear 27 on both sides to rotate on the surface of the first fixed shaft 26.

[0026] Furthermore, the second fixed shaft 28 is symmetrically distributed in two sets inside the protective shell 21, and the second gear 29 is symmetrically distributed in two sets on both sides of the connecting rotating rod 210. The second gear 29 is rotatably connected to the surface of the first gear 27 and the second fixed shaft 28. The rotation of the first gear 27 drives the second gear 29 to rotate synchronously on the surface of the second fixed shaft 28, thereby driving the connecting rotating rod 210 to rotate, which in turn drives the clamping block 212 to rotate.

[0027] Furthermore, the connecting rod 210 is rotatably connected to the surface of the second gear 29 and the second fixed shaft 28. The clamping block 212 is fixedly connected to the surface of the connecting rod 210 via the fixed threaded rod 211. The clamping block 212 is rotatably connected to the surface of the adjusting plate 2 via the connecting rod 210. The rotation of the connecting rod 210 causes the clamping block 212 to rotate, thereby clamping the flexible circuit board. The sleeve connection between the fixed threaded rod 211 and the clamping block 212 allows for the installation of clamping blocks 212 of different sizes to accommodate flexible circuit boards of different specifications.

[0028] Furthermore, the adjusting grooves 3 are symmetrically distributed in two sets on the surface of the processing platform 1. The clockwise threaded rod 32 is rotatably connected to the surface of the adjusting groove 3 via the adjusting handle 31. The limiting rod 33 is rotatably connected to the interior of the processing platform 1 via the clockwise threaded rod 32. The counterclockwise threaded rod 34 is rotatably connected to the surface of the adjusting groove 3 via the limiting rod 33. Rotating the adjusting handle 31 can drive the clockwise threaded rod 32, the limiting rod 33 and the counterclockwise threaded rod 34 to rotate synchronously. The threaded grooves on the surfaces of the clockwise threaded rod 32 and the counterclockwise threaded rod 34 rotate in opposite directions, thereby causing the connecting blocks 35 on their surfaces to move towards each other.

[0029] Furthermore, the connecting block 35 is movably connected to the surface of the processing platform 1 via the clockwise threaded rod 32, and the connecting block 35 is movably connected to the surface of the processing platform 1 via the counterclockwise threaded rod 34. The clockwise threaded rod 32 and the counterclockwise threaded rod 34 rotate synchronously, thereby driving the two sets of adjusting plates 2 to move towards each other, thereby changing the effective distance between the two sets of protective shells 21.

[0030] Working principle: When using the processing platform 1, first place one end of the flexible circuit board between the two sets of clamping blocks 212. The starting cylinder 22 drives the connecting rod 23 to move, thereby driving the rack plate 24 to move, so that the first gear 27 drives the second gear 29 to rotate synchronously, so that the connecting rotating rod 210 drives the clamping block 212 to rotate, thereby clamping one end of the flexible circuit board. Then, according to the specifications of the flexible circuit board, adjust the distance between the two sets of adjusting plates 2. By rotating the adjusting handle 31, the clockwise threaded rod 32, the limiting rod 33 and the counterclockwise threaded rod 34 can be driven to rotate synchronously. The thread grooves on the surface of the clockwise threaded rod 32 and the counterclockwise threaded rod 34 turn in opposite directions, so that the two sets of adjusting plates 2 move towards each other, thereby changing the effective distance between the two sets of protective shells 21. Then, the other end of the flexible circuit board can be clamped in the same way.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
