However, this bending method has high mold investment costs, long mold production cycles, and requires large-scale equipment in production. Therefore, a simple pin bending fixture is needed, which can achieve the bending of metal conductive pins while having the advantages of small size, simple structure, low manufacturing cost, and simple operation method.

[0010] Two positioning platforms are symmetrically arranged at two ends of the upper mold and can be plugged and matched with the two positioning grooves.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] refer to Figure 1-3 A simple fixture for bending pins includes a lower die 1 and an upper die 2 that can be pressed together. The lower die 1 includes at least one lower avoidance groove 11 and two lower die grooves 12; the two lower die grooves 12 are symmetrically arranged on both sides of the lower avoidance groove 11, and the depth of the lower die groove 12 can be greater than the depth of the lower avoidance groove 11.

[0025] The upper mold 2 includes at least one upper avoidance groove 21 and two upper mold bosses 22. The two upper mold bosses 22 are symmetrically arranged on both sides of the upper avoidance groove 21, and can be pressed together with the lower mold groove 12 to achieve the bending of the pins of the LED light source module 4; the lower mold groove 12 and the upper mold boss 22 can both be long strips, and both ends have rounded corners, which can make the lower mold groove 12 and the upper mold boss 22 smoother when pressed together, and at the same time avoid damage to the fixture caused by sharp corners.

[0026] The lower air avoidance groove 11 and the upper air avoidance groove 21 are pressed into a placement cavity, and the LED light source module 4 can be placed in the placement cavity. The shape and size of the placement cavity are adapted to the LED light source module 4, which can avoid the problem of incomplete pressing or loosening after pressing caused by the mismatch between the size of the LED light source module 4 and the placement cavity when the lower mold 1 and the upper mold 2 are pressed together, thereby improving the positioning accuracy of the LED light source module 4 in the placement cavity and ensuring the bending accuracy.

[0027] A positioning unit 3 is provided between the lower mold 1 and the upper mold 2. The positioning unit 3 includes two positioning grooves 31 and two positioning platforms 32. The two positioning grooves 31 are symmetrically arranged at both ends of the lower mold 1; the two positioning platforms 32 are symmetrically arranged at both ends of the upper mold 2, and the positioning platforms 32 can be plugged into and matched with the positioning grooves 31 to achieve positioning when the lower mold 1 and the upper mold 2 are pressed together; the cross-sections of the positioning grooves 31 and the positioning platforms 32 can both be U-shaped, which can make the lower mold groove 12 and the upper mold boss 22 smoother when pressed together, and at the same time avoid damage to the fixture caused by sharp corners.

[0028] A mounting unit 23 is also provided on the top of the upper mold 2. The mounting unit 23 may be a threaded hole, through which the upper mold 2 and the driving device can be detachably connected. The driving device may be a small pneumatic device or a small hydraulic device to increase the clamping force when the upper mold 2 and the lower mold 1 are pressed together.

[0029] In some embodiments, the threaded hole is concentrically disposed on the top of the upper mold 2 , so that the force on the upper mold 2 is more uniform, thereby improving the bending consistency of the LED light source module 4 .

[0030] In some embodiments, two positioning grooves 31 are provided on both end surfaces of the lower mold 1 to facilitate observation of the pressing process of the lower mold 1 and the upper mold 2 so as to facilitate timely adjustment.

[0031] The specific working principle is as follows:

[0032] When using this jig to bend the pins of the LED light source module, first place the LED light source module 4 in the lower avoidance groove 11 of the lower mold 1 to ensure that the size of the LED light source module 4 is compatible with the placement cavity. Then, it is connected to the drive device through the installation unit 23, and the drive device moves downward to close the upper mold 2 and the lower mold 1, and finally, with the cooperation of the lower mold groove 12 and the upper mold boss 21, the pins of the LED light source module 4 are bent. During the pressing process, the positioning groove 31 of the positioning unit 3 is plugged into the positioning platform 32 to ensure the precise alignment of the upper mold 2 and the lower mold 1, thereby ensuring the accuracy of the bending. The utility model can realize the rapid installation and disassembly of the upper mold 2 and the drive device, and improve the versatility and convenience of operation of the jig.
