With the development of the electronic connector towards miniaturization and precision, higher requirements are put forward for the pin operation of the product. The traditional pin operation is mostly carried out in an artificial way, which is labor-intensive and inefficient. The existing pin operation is completed by a pin inserting machine to replace the traditional manual pin inserting, so as to improve the pin inserting efficiency and the production efficiency of the product. However, the pin inserting operation of the pin inserting machine is only in a straight structure, and more and more products require bending operation of the needle to meet the pin requirements of different products.
