Description

Technical Field

[0001] The utility model relates to the technical field of laser welding, in particular to laser welding equipment with a smoke and dust adsorption function. Background Art

[0002] The principle of laser welding is to use a laser to emit high-energy laser, which melts the surface and interior of the workpiece to be welded together; during the welding process, the high-energy laser beam moves at high speed on the surface of the object to complete the fusion welding. In the actual welding process, welding slag splashing is inevitable.

[0003] After searching, it was found that the published application number CN202222387633.5 mentioned a laser welding device, which is used to solve the technical problem that welding slag easily splashes and falls into the interior and surface of the workpiece during the existing welding process, resulting in poor workpiece quality. In the utility model, the laser welding assembly is rotatably connected to the support plate on the workbench, and the carrier assembly is located above the laser welding assembly; when the laser welding equipment is in operation, the laser emitting end of the laser welding assembly is facing the workpiece on the carrier assembly, and the line connecting the center of the carrier assembly and the center of the laser welding assembly forms a first preset inclination angle with the plane where the workbench is located. In this embodiment, the line connecting the center of the carrier assembly and the center of the laser welding assembly forms a first preset inclination angle with the plane where the workbench is located, and the carrier assembly is above the laser welding assembly. Through this design, during the welding process, the welding slag splashed downward due to gravity will not splash onto the workpiece of the carrier assembly, effectively ensuring the quality of the workpiece.

[0004] Although the above solution solves the problems mentioned in the background technology, it still has the following shortcomings: although the laser welding equipment in the above solution can block the welding slag, it cannot collect the smoke generated during the laser welding process. The smoke in the air will cause harm to the health of workers. Utility Model Content
