Product description

The top cover soft connection laser welding machine is mainly used for laser welding of battery tab soft connection sheet and top cover pole in EV aluminum shell battery. The core components are 6000W fiber laser of German IPG company, Germany SCANLAB high-power galvanometer, and simulation based hydrodynamic dust removal structure design. It can be used for 24-hour continuous and stable welding. The equipment integrates the top cover scanning and loading, code cutting and code scanning, jelly-roll electrode scanning and loading, top cover connection sheet laser welding, dust removal, weld mark CCD detection, jelly-roll electrode off-loading and other processes.
