[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of 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.

[0024] Embodiment 1

[0025] Combined with Figure 1 A FPC circuit board bending and shaping device comprises a mounting plate 1, wherein the four corners of the mounting plate 1 are provided with mounting holes 2, the top of the mounting plate 1 is provided with a placement plate 3, and both sides of the placement plate 3 are provided with fixed pressing structures.

[0026] Through the above structure, the device can be directly fixed on any target work surface by using the mounting plate 1 and the mounting hole 2, which is convenient for operation.

[0027] Combined with Figure 1 and attached Figure 3 The fixed pressing structure includes an L-shaped plate 14 invertedly arranged on both sides of the placement plate 3, and a threaded stud 15 is inserted on the L-shaped plate 14. A knob 16 is provided at the top of the stud 15, and a rotatably connected pressure plate 17 is provided at the bottom of the stud 15. Insertion grooves 4 are provided on both sides of the placement plate 3.

[0028] Through the above structure, the knob 16 is rotated to drive the stud 15 to rotate continuously, and the pressing plate 17 located at the bottom end of the stud 15 moves downward continuously, so as to press and fix the edges of both sides of the FPC circuit board on the placement plate 3.

[0029] Combined with Figure 3 The bottom end of the pressing plate 17 is provided with a silicone layer, which can protect both sides of the FPC circuit board during pressing to avoid damage caused by excessive pressing.

[0030] Embodiment 2

[0031] Combined with Figure 2 and attached Figure 4 A fixing plate 5 is provided at both ends of one side of the mounting plate 1, a rotating shaft 6 is provided between the fixing plates 5, a bending plate 7 is provided on one side of the rotating shaft 6, a disc 9 is provided on one side of the fixing plate 5, a scale 10 is provided on the disc 9, a plurality of through grooves 11 corresponding to the scales 10 are provided on the disc 9, and a limiting piece 12 is inserted in the through groove 11.

[0032] Through the above structure, the limiting plate 12 is directly inserted into the through groove 11. As the bending plate 7 continues to move closer, when the bending plate 7 directly moves to the limiting plate 12, it can be directly bent to the scale corresponding to the through groove 11 at this time, which is convenient for bending the FPC circuit board into various angles and facilitating processing operations.

[0033] Combined with Figure 2 and attached Figure 4 The rotating shaft 6 extends to one end outside the fixed plate 5 and is provided with a turning handle 8. A grip ring 13 is provided on one side of the limiting plate 12. Both ends of the rotating shaft 6 are rotatably connected to the fixed plate 5 through bearings, and the stud 15 is rotatably connected to the pressure plate 17 through bearings.

[0034] Through the above structure, the rotating handle 8 can be used to drive the rotating shaft 6 to rotate, which is convenient for adjustment. The limiting piece 12 can be easily pulled out and inserted into the through groove 11 through the grip ring 13, which is convenient for hand holding.

[0035] When the utility model is implemented:

[0036] Put the FPC circuit board to be processed into the insertion slot 4 and push it forward until it extends above the pressure plate 17. Then turn the knobs 16 on both sides to drive the studs 15 to rotate continuously, and the pressure plate 17 moves down continuously to clamp and fix the edges of both sides of the FPC circuit board. The silicone pad at the bottom of the pressure plate 17 can provide buffer protection for the FPC circuit board to avoid damage caused by excessive clamping.

[0037] Then hold the grip ring 13 and insert the limit plate 12 directly into the through slot 11 corresponding to the scale 10. Hold the handle 8 with one hand and turn it to drive the shaft 6 to rotate continuously. The bending plate 7 follows the rotation and directly performs the bending and shaping operation on the FPC circuit board. The bending plate 7 rests on the limit plate 12, and the FPC circuit board with multiple angles can be directly bent. Not only can the FPC circuit board with multiple angles be bent without the need to replace equipment, reducing production costs and time, but also it is easy to operate and there is no need to compare the scale 10 multiple times, which is convenient to use.
