Description

Technical Field

[0001] The invention relates to the field of energy storage batteries, and more particularly to a dust removal brush device after laser welding. Background Art

[0002] At present, in the production process of square batteries, according to the process sequence requirements, the core will be soft-connected and the cover will be laser welded, the purpose of which is to weld the core and the cover together to form a battery. Welding slag dust will be generated during the welding process. Welding slag dust will fall into the battery and affect the battery performance and cause the battery to be scrapped. In severe cases, it will cause a short circuit and directly affect the safety performance of the battery.

[0003] The Chinese patent with publication number CN112917030B discloses an automatic welding slag cleaning device for a battery module integrated cover.
