Abstract

The invention discloses a novel combined dust removal device for laser welding of a power battery module. The novel combined dust removal device comprises a module positioning mechanism, a needle plate copper nozzle blowing mechanism and a dust collection mechanism, wherein the module positioning mechanism comprises a base and a needle plate fixing frame, a tray is arranged at the top of the base,the power battery module is placed at the top of the tray, the needle plate fixing frame is located over the tray, a long-strip-shaped groove is formed in the needle plate fixing frame, the needle plate copper nozzle blowing mechanism is installed in the long-strip-shaped groove, the dust collection mechanism comprises a dust collection pipeline and a dust collection hood, the dust collection hood is connected to external dust collection equipment through the dust collection pipeline, and the dust hood is positioned on the needle plate copper nozzle blowing mechanism. According to the novel combined dust removal device for the laser welding of the power battery module, the device is scientific in structural design, capable of timely and reliably removing smoke and welding slag generated in a welding process when laser welding is conducted on a busbar of the power battery module, smoke pollution in the welding process is effectively reduced, and therefore laser energy loss in the welding process is reduced, and the welding quality of the busbar of the power battery module is improved.

Description

technical field [0001] The invention relates to the technical field of welding equipment, in particular to a novel combined dust removal device for laser welding of power battery modules. Background technique [0002] At present, the busbar welding process of the power battery module is a very important part of the power battery module assembly (Pack) process. During welding (specifically laser welding), the smoke and welding slag generated will absorb and reflect the laser. , leading to the problem of virtual soldering of the busbar, thereby reducing the yield rate of the power battery module assembly (Pack). At the same time, the smoke and dust permeating the air will also pollute the environment of the workshop and seriously endanger the health of operators. Contents of the invention [0003] The purpose of the present invention is to provide a novel combined dust removal device for laser welding of power battery modules in view of the technical defects in the prior ar...
