[0002] In the field of eyewear manufacturing, the quality and appearance of eyeglass frames are crucial to the overall quality of glasses. As consumers' requirements for glasses continue to increase, eyeglass frames not only need to have good functionality, such as comfortable wearing and accurate optical correction, but also need to have exquisite appearance design to meet fashion needs. The welding process plays a key role in the processing of eyeglass frames. It can firmly connect different components together to ensure the structural stability and integrity of the eyeglass frames.

[0003] The existing welding machines for processing eyeglass frames still have the following technical problems when in use, such as:

[0004] 1. When using the existing welding machine for eyeglass frame processing, the staff needs to manually fix the eyeglass frame under the welding pen, and then start the welding machine to weld the eyeglass frame. In this way, since the welding pen will hinder the staff from manually fixing the eyeglass frame in the welding position, it will not only reduce the work efficiency, but also be unfavorable to reduce the labor intensity of the staff;

[0005] 2. When the existing welding machine for processing eyeglass frames is in use, a sliding mechanism is also used to allow the welding table for fixing the eyeglass frames to slide, thereby preventing the welding pen from hindering the fixing of the eyeglass frames. However, in the process of sliding the welding table, it is not conducive to ensuring the stability of the welding table, thereby not being conducive to the stable fixing of the eyeglass frames on the welding table;

[0006] 3. The existing welding machines for processing eyeglass frames cannot automatically perform welding when in use, so that the degree of automation is not high;
