Description

Technical Field

[0001] The utility model relates to the field of laser welding machines, in particular to a laser welding machine with a protective function. Background Art

[0002] Laser welding machine, also often called laser welding machine, laser welding machine, is a machine used for laser welding of material processing. According to its working mode, it can be divided into laser mold welding machine (manual welding machine), automatic laser welding machine, laser spot welding machine, fiber transmission laser welding machine, etc. The working principle of the laser welding machine is to use high-energy laser pulses to locally heat the material in a small area. The energy of the laser radiation diffuses to the inside of the material through heat conduction, and the material is melted to form a specific molten pool to achieve the purpose of welding. This method is mainly aimed at the welding of thin-walled materials and precision parts, and can realize spot welding, butt welding, lap welding, sealing welding, etc. In the existing patent application with application number CN202022919991.7, a laser welding machine with a protective cover is proposed. Although the protective cover set on it can surround the electric workbench inside, so that when the workpiece is welded, sparks will not fly around, and the protective cover is made of brown transparent glass, which can block the flames generated during welding and reduce light pollution, but smoke will be generated during laser welding. These smoke are mainly composed of metal oxides, non-metallic oxides and other particles. Since there is no component to purify the smoke on the laser welding machine, the smoke will cause damage to the health of the surrounding workers. In particular, long-term exposure to welding smoke may lead to respiratory diseases, skin irritation and other problems, so it needs to be improved. Utility Model Content
