Description

technical field [0001] The invention relates to the technical field of lithium battery production equipment, in particular to a bottom spot welding machine for cylindrical lithium batteries and a spot welding method implemented by the bottom spot welding machine. Background technique [0002] Lithium batteries have the advantages of stable output voltage and high current discharge. During use, they will not cause combustion or explosion due to overcharging or overdischarging. They are widely used in various lamps, electric tools, and children's toy models. [0003] Spot welding is one of the most important processing procedures in the production and processing of lithium batteries. Whether the spot welding at the bottom of lithium batteries is good or not is directly related to the production quality of batteries. In the prior art, the operator arranges the lithium batteries to be processed into the processing tray, and places nickel sheets on the lithium batteries. The ope...
