Especially among women, diamond earrings are often regarded as a fashion accessory and a symbol of taste. With the increase of popularity, the demand is increasing, and fully automatic and fast production has become the current development trend.

[0003] Diamond earrings are mainly composed of ear pins, diamond holders and diamonds. During the production process, the ear pins and diamond holders need to be welded together. The existing welding method is to clamp the ear pins in a vise, hold the diamond holder with one hand, and hold a welding gun with the other hand for welding. This method requires clamping the ear pins and welding them one by one, which has low production efficiency and cannot meet existing production needs. In addition, since the diamond holder and the ear pins are manually aligned, there are errors, resulting in distortion of the welded products and defective products. At the same time, during the welding process, welding slag is easy to splash, thereby causing harm to the staff and posing a safety hazard. Summary of the invention
