Description

Technical Field

[0001] The present invention relates to the technical field of laser welding, and particularly relates to a spot welding device for glasses processing. Background Art

[0002] Laser welding is an efficient and precise welding method that uses a laser beam with a high energy density as the heat source. Laser welding is an important aspect of the application of laser material processing technology. The welding process belongs to the heat conduction type, that is, the laser radiation heats the surface of the workpiece, and the surface heat diffuses inward through heat conduction. By controlling parameters such as the width, energy, peak power, and repetition frequency of the laser pulse, the workpiece is melted to form a specific molten pool.

[0003] Glasses are composed of lenses and frames, and are used to improve eyesight, protect the eyes or for decorative purposes. During the glasses processing, laser spot welding is required to weld the frames.

[0004] Based on the existing laser welding equipment in the prior art, when welding the frame of glasses, it can usually only achieve the adjustment of the welding torch in a single horizontal or vertical direction. Since the bending angles of the glasses temples are diverse (such as arc transitions), a single adjustment axis is difficult to cover complex welding paths, and the fixture needs to be frequently replaced, resulting in low work efficiency.
