AI Technical Summary

Technical Problem

The spatter generated during laser welding is difficult to completely remove by the dust collection device, causing some of the spatter to fall onto the surface or inside of the workpiece, affecting the quality of battery processing.

Method used

Design a dust removal mechanism, including a housing, a light-transmitting component, a blocking component, and a dust removal component. The housing blocks splashes by abutting against the workpiece, and the air extraction pipe and air blowing pipe system remove the splashes to prevent them from falling on the workpiece and damaging the light-transmitting component.

Benefits of technology

It improves battery processing quality, prevents spatter from affecting workpieces and the environment, extends the service life of light-transmitting components, and improves welding quality and production efficiency.

Abstract

The embodiment of the application provides a dust removal mechanism and a welding device, and relates to the technical field of battery welding. The dust removal mechanism comprises a shell, the shell is arranged on the welding device, a first welding port is arranged on the shell, the first welding port is used for being opposite to a welding part of a workpiece when the shell abuts against the workpiece, a light transmission assembly is arranged on the shell, the light transmission assembly is connected with the connecting port, the light transmission assembly is used for allowing a laser of the welding device to pass through, so that the laser welds the welding part through the first welding port, a blocking assembly is connected with the shell, the blocking assembly is used for preventing spatter in the shell from moving towards the light transmission assembly, and a dust removal assembly is arranged on the shell, the dust removal assembly is used for removing the spatter generated when the welding device welds. The dust removal mechanism and the welding device can improve the removal degree of the spatter generated when welding, thereby indirectly improving the processing quality of the battery.
