The invention discloses a rotary disc type full-automatic multi-station laser welding machine comprising a rack provided with a rotary disc, rotary disc driving equipment, a battery module feeder, N-2battery module laser welding mechanisms and a battery module discharge mechanism. The rotary disc is provided with a vertical central axis, can do pivotal motion around the central axis of the rotarydisc and is provided with N battery module locating seats which are distributed evenly at intervals in the circumferential direction with the central axis of the rotary disc as the center, and N is larger than or equal to 4. The rotary disc driving equipment is in transmission connection with the rotary disc so as to drive the rotary disc to do pivotal motion around the central axis of the rotarydisc. The battery module feeder, the N-2 battery module laser welding mechanisms and the battery module discharge mechanism are arranged around the rotary disc. According to the rotary disc type full-automatic multi-station laser welding machine, a battery single body and a battery series piece on a battery module are fixedly welded in a regional welding mode, and welding efficiency and welding quality of the battery module are improved.
Description
technical field [0001] The present application relates to the technical field of battery welding, in particular to a turntable-type fully automatic multi-station laser welding machine for cylindrical lithium-ion battery modules. Background technique [0002] To assemble lithium-ion power battery modules for electric vehicles, thousands of cylindrical lithium-ion batteries must be connected in series and parallel. Welding is the most important process. The aforementioned "welding" refers to: pre-inserting multiple battery cells into the battery insertion holes of the plastic battery fixture used in the battery module, and then inserting them into the battery insertion holes to contact and connect with the positive terminals of the battery cells. The battery series sheet, and then use a welding machine to weld the battery series sheet and the battery cell. In the prior art, resistance welding is generally used, which has the advantage of less heat generation and less damage t...
