The existing method is to perform bending processing when corresponding to the specific circuit board type, design corresponding tooling corresponding to different pin bending lengths, and perform bending processing before the operator specifically performs photodiode welding.

[0003] Specifically, manual positioning of the pins is required during bending, resulting in inconsistent lengths of the bent pins. For batch circuit board welding production lines, the efficiency is low and the bending consistency cannot be guaranteed. Utility Model Content
