Description

technical field [0001] The invention relates to the technical field of battery welding technology, in particular to an automatic ultrasonic welding and film sticking technology of a lithium battery. Background technique [0002] Lithium batteries have the advantages of high capacity, small size, and light weight. Lithium battery packs composed of multiple lithium battery cells are used in many fields due to their higher capacity. For example, in computers, in order to reduce the thickness of notebooks At the same time, to increase the capacity of the battery, it is necessary to use more than one lithium battery in series to increase the battery capacity. Therefore, the poles of each single battery need to be connected by means of a flexible connection structure, and at the same time need to be welded to form a battery pack. At present, most of the welding on the market is manual welding or semi-automatic equipment welding. The whole process requires a certain degree of prec...
