Busbar welding device
The present disclosure discloses a busbar welding device comprising a rack, a positioning mechanism, a compressing mechanism and a welding mechanism. The positioning mechanism is located at the bottom of the rack and comprises a base, a conveying mechanism and a positioning plate. The conveying mechanism is arranged on the base and capable of conveying/receiving a battery module to/from the position above the positioning plate. A jacking part capable of elevating is arranged on the base. The positioning plate is located on the base and capable of positioning the battery module in a length direction and a width direction. The compressing mechanism comprises pressing plates movably arranged on the rack and capable of movably compressing busbars of the battery module located on the positioning plate. The welding mechanism is movably arranged on the rack and used for welding the busbars. The positioning plate positions the battery module in the length direction and the width direction and then compresses the busbars of the battery module by the pressing plates. There is no need to compress each busbar before welding it after positioning performed by the positioning plate so that the welding efficiency is improved, and the welding quality and precision are better.
