[0002] Due to the rapid development of the optoelectronics industry, more and more FPC flexible boards are used to connect PCBs and devices. In order to ensure welding quality, module size and smooth optical path, the length of the FPC flexible board needs to be accurately controlled. At the same time, due to the limitation of the internal size of the module, the width of the FPC flexible board is also strictly controlled. However, an FPC flexible board that is too short and too narrow is not conducive to the production of the front-end process. In order to facilitate the front-end process, the FPC flexible board is usually lengthened and widened, and then sheared before welding. However, manual shearing can easily lead to poor consistency in the size of the FPC flexible board and uneven incisions, which will have an adverse effect on subsequent welding and FPC flexible board size control.

[0025] Reference Figure 1-4 The utility model provides an FPC cutting jig, including an FPC support seat 4, a device support seat 14 and a tool assembly; the FPC support seat 4 is detachably mounted with a positioning plate 5; the FPC support seat 4 is provided with a clamping assembly for fixing the FPC; the device support seat 14 is arranged on one side of the FPC support seat 4 and a cutting groove is formed between the device support seat 14 and the FPC support seat 4; the cutting groove is located within the cutting stroke of the tool assembly. Figure 1 As shown, when in use, the device 2 welded to one end of the FPC board 1 is placed on the device support seat 14, and the part to be cut 101 is placed on the positioning plate 5, so that the cutting line 102 is located in the cutting groove, and the FPC board 1 is cut by the tool assembly.

[0026] Specifically, the positioning plate 5 is provided with a positioning groove matching the portion 101 to be cut off of the FPC board 1. Since the size of the positioning groove matches the size of the portion 101 to be cut off of the FPC board 1, the cutting line 102 can be accurately positioned to ensure cutting consistency. When it is necessary to cut the FPC board 1 of different products, the positioning plate 5 with positioning grooves of different sizes can be replaced to improve the applicability of the fixture.

[0027] Furthermore, the FPC clamping assembly includes a clamping block 6, a clamping block shaft seat 602 and a locking piece; the clamping block shaft seat 602 and the locking piece are respectively installed on both sides of the positioning groove; one end of the clamping block 6 is rotatably connected to the clamping block shaft seat 602 through a rotating shaft, and the other end is detachably connected to the locking piece. Figure 2 As shown, the pressing block 6 is turned over to naturally stay at the rear limit, and the portion 101 to be cut off of the FPC board 1 of the device 2 is installed into the positioning groove, and it is required to ensure that at least two sides of the FPC board 1 are aligned with the edges of the positioning groove. After the FPC board 1 is assembled, the pressing block 6 is turned downward to press the portion 101 to be cut off of the FPC board 1, and the pressing block 6 is fixed by the locking member to press the portion 101 to be cut off of the FPC board 1 tightly in the positioning groove.

[0028] Specifically, the locking member includes a locking screw 7; one end of the locking screw 7 is mounted on the FPC support seat 4, and the other end is sleeved with a locking nut 8; the connection end of the pressure block 6 and the locking member is provided with a slot 601 matching the outer diameter of the locking screw 7; the pressure block 6 is detachably connected to the locking screw 7 through the locking nut 8 and the slot 601. Before assembling the FPC board 1, first loosen the locking nut 8 to disengage the slot 601 of the pressure block 6 from the locking screw 7. After the FPC board 1 is assembled, flip the pressure block 6 so that the slot 601 at its end is engaged with the outer side of the locking screw 7, and tighten the locking nut 8 downward to fix the pressure block 6 and the locking screw 7, thereby fixing the FPC board 1.

[0029] Preferably, the locking member further comprises a screw shaft seat 9 mounted on the FPC support seat 4; one end of the locking screw 7 is rotatably mounted on the screw shaft seat 9, and the other end is sleeved with a locking nut 8. Before assembly, Figure 2 As shown, after loosening the locking nut 8, let the locking screw 7 droop naturally, then flip the pressure block 6 upward and backward to let it naturally stay at the rear limit position, install the device 2 FPC board 1 to be cut 101 into the positioning groove of the positioning plate 5, then flip the pressure block 6 downward to press the FPC board 1, and then flip the locking screw 7 upward, and fix the pressure block 6 and the locking screw 7 by tightening the locking nut 8, and then fix the FPC board 1, and complete the clamping of the FPC board 1.

[0030] In an optimized implementation, the FPC cutting jig further includes a counting component for counting the number of cutting times of the tool assembly.

[0031] Specifically, the counting component includes a counter 16 and a sensor 15 for sensing the movement of the tool; the counter 16 is connected to the sensor 15. When the tool component is cutting, the sensor 15 is automatically triggered to send a signal, and the counter 16 automatically counts once according to the received signal to count the use of the tool. The sensor 15 and the counter 16 are preferably a Hall sensor 15 and a Hall counter 16.

[0032] Furthermore, the tool assembly includes a shearing knife rotating shaft seat 10 and a shearing knife; the shearing knife is rotatably mounted on the shearing knife rotating shaft seat 10. The cutting groove is located in the rotation path of the shearing knife, that is, in the cutting stroke of the tool assembly. By rotating the shearing knife, the FPC board 1 is cut in the cutting groove.

[0033] In order to maintain the FPC shearing effect during operation, the shearing knife includes a knife holder 11 and a shearing blade B12 detachably mounted on the knife holder 11; the knife holder 11 is rotatably mounted on the shearing knife shaft seat 10.
