Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0020] Reference Figure 1-4 , a FPC flexible circuit board bending test device, comprising a bottom plate 1, the top of the bottom plate 1 is fixedly connected to an inverted U-shaped support frame 2, the side wall of the inverted U-shaped support frame 2 is rotatably connected to a threaded rod 5, the surface of the threaded rod 5 is threadedly connected to a nut block 4, and the bottom end of the nut block 4 is provided with a pressure assembly;

[0021] It should be noted that: the threaded rod 5 is driven to rotate by the mobile motor 3, so that the nut block 4 drives the cylinder 6 to move back and forth, and then drives the pressure roller 8 to move back and forth, thereby realizing the reciprocating rolling function of the circuit board.

[0022] A moving motor 3 is installed on the side wall of the inverted U-shaped support frame 2, and the output shaft of the moving motor 3 is fixedly connected to one end of the threaded rod 5. A clamping motor 15 is installed on the top of the bottom plate 1, and one end of the output shaft of the clamping motor 15 is fixedly connected to a bidirectional screw 16. A pair of symmetrical connecting plates 14 are threadedly connected to the surface of the bidirectional screw 16. Casters 13 are installed at both ends of the connecting plates 14. The top of the casters 13 is fixedly connected to a column 12, and the top of the column 12 is fixedly connected to a clamping plate 11;

[0023] It should be noted that: when the clamping motor 15 is turned on, the clamping motor 15 drives the bidirectional screw 16 to rotate, so that the connecting plates 14 on both sides drive the clamping plates 11 to move toward each other, thereby realizing the clamping and fixing function of the circuit board (the edge of the circuit board is clamped with the card slot).

[0024] A slot is provided on one side of the clamping plate 11, and a temporary support plate 17 is fixedly connected to one side of the clamping plate 11 near the bottom end;

[0025] It should be noted that the card slot is engaged with the edge of the circuit board to prevent the circuit board from being separated from the clamping plate 11 during the bending process, and the temporary support plate 17 can play a supporting role before the clamping plate 11 clamps the circuit board.

[0026] The top of the clamping plate 11 is fixedly connected to a vertical plate, the top of the vertical plate is fixedly connected to a baffle 10, the pressure assembly includes a cylinder 6 installed at the bottom end of the nut block 4, a moving shaft fixedly connected to the output end of the cylinder 6 and a mounting frame 7 fixedly connected to the bottom end of the moving shaft, the inner side of the mounting frame 7 is rotatably connected to a pressure roller 8, and the two side surfaces of the mounting frame 7 are fixedly connected to positioning plates 9;

[0027] It should be noted that: the cylinder 6 is used to drive the mounting frame 7 to move downward and then drive the pressure roller 8 to press the circuit board downward, so that the circuit board is bent, thereby realizing the circuit board bending detection function;

[0028] It is worth noting that when the baffle 10 contacts the positioning plate 9, it indicates that the pressure exerted on the circuit board by the pressure roller 8 driven by the cylinder 6 has reached the test pressure.

[0033] When the utility model is used, multiple circuit boards to be tested are placed on the temporary support plate 17, and then the clamping motor 15 is turned on.

[0034] Then, the moving motor 3 is turned on, and the moving motor 3 drives the threaded rod 5 to rotate, so that the nut block 4 drives the cylinder 6 to move, and then drives the pressure roller 8 to move, so that the positioning plate 9 moves to above the baffle 10, and then the cylinder 6 is turned on, and the cylinder 6 drives the mounting frame 7 to move downward, and then drives the pressure roller 8 to move downward and bend the circuit board until the positioning plate 9 contacts the baffle 10, and then the moving motor 3 is turned on again, so that the pressure roller 8 moves back and forth, realizing the bending function of multiple circuit boards, and then realizing the bending test function of multiple circuit boards, thereby greatly improving the bending test efficiency of the circuit boards, and at the same time greatly reducing the number of times the staff operates the circuit board clamping and disassembly and assembly, reducing the workload of the staff.
