The invention provides equipment for welding a battery connecting piece in a battery pack. The equipment comprises a cutting device, a laser and a mechanical arm, wherein the cutting device is mountedon the mechanical arm and is used for cutting a material strap into a connecting piece; and the laser is mounted on the mechanical arm and is used for welding the connecting piece on an electrical core in the battery pack. The invention further provides a welding method. At first, the cutting device is adopted to cut the material strap into the connecting piece, and then the laser is started to weld the connecting piece on the electrical core. The welding equipment and the welding method are high in degree of automation, reduce investment of manpower and equipment, decrease the welding cost and improve the welding efficiency.
Description
technical field [0001] The invention belongs to the technical field of battery manufacturing, and more specifically relates to a welding device and a welding method for battery connecting pieces in a battery pack. Background technique [0002] Lithium batteries have the advantages of high storage energy density, long service life, high rated voltage, light weight, etc., and are widely used in power tools, aerospace, laptop computers, communication equipment and other fields. [0003] The lithium battery module includes a casing and a battery cell set inside the casing. The battery cells are connected to the conductive columns drawn from the battery cells through connecting pieces, so as to connect the battery cells in parallel or in series. [0004] In traditional lithium battery production equipment, the connecting piece is stamped in advance, and then the connecting piece is manually placed between the two cells for laser welding. The labor and equipment investment is larg...
