Description
technical field [0001] The invention relates to the field of lithium battery laser welding devices, in particular to a lithium battery laser welding device for new energy vehicles and a method for using it. Background technique [0002] Laser welding uses the laser beam as the energy source, and uses the focusing device to condense the laser beam into a high-power-density beam to irradiate the surface of the workpiece for heating, and the inside of the material melts to form a specific molten pool under the action of heat conduction of the metal material. When laser welding is used, the heat-affected zone of the workpiece is small, the solder joints are small, the welding dimensional accuracy is high, and the welding method is non-contact welding. Under the demand of intelligent manufacturing upgrades and the continuous improvement of the safety performance of power lithium batteries, more and more advanced Laser equipment is playing a key role in lithium-ion battery manufac...
