Integrated automated production line for assembling of battery cells

Abstract

The invention discloses an integrated automated production line for assembling of battery cells. The integrated automated production line for assembling of battery cells comprises a battery cell pairing and welding station, a top cap welding station, a tab bending station and a station for feeding battery cells into shells, wherein the battery cell pairing and welding station is used for pairing tabs of two battery cells and welding and fixing the tabs of the battery cells; the top cap welding station is connected with the battery cell pairing and welding station, and is used for welding a topcap to the tabs, which are welded and fixed, of the two battery cells; the tab bending station is connected with the top cap welding station, and is used for bending the tabs of the two battery cellsso as to attach the two battery cells; and the station for feeding the battery cells into the shells is connected with the tab bending station and is used for pressing the two attached battery cellsinto an aluminum shell and fixing the two attached battery cells. Procedures of pairing and welding of the tabs of the battery cells, top cap welding, battery cell combining, feeding of the battery cells into the shells and the like can be finished successively. Compared with a traditional single machine for line distribution, the integrated automated production line saves more space, the variousstations work according to set action sequences, the degree of automation is high, the labor cost is low, the production efficiency is improved, and the maintenance cost is reduced; and meanwhile, owing to an integrated design overall arrangement, the structure is compact and clear, high production aesthetic feeling is achieved, and the practicality is high.

Description

Technical field [0001] The invention belongs to the field of battery automated production equipment, and specifically relates to an integrated automated production line for battery cell assembly. Background technique [0002] Lithium battery is a kind of high-efficiency battery, which is widely used in electronic products, new energy vehicles and other industries due to its high energy density and lightness. The battery cell is the core energy storage component of the lithium battery. For electronic products with greater power requirements, the lithium battery used is generally assembled by battery cells in series and parallel. [0003] In the production process of assembling the battery cells in series and parallel to form a battery, it is necessary to sequentially carry out the processes of pairing welding of the battery cell tabs, top cover welding, cell closing, and shell insertion. The battery core has two electrodes. The welding process is to weld the tabs of the same electr...

Problems solved by technology

At present, domestic battery manufacturers all adopt a semi-automatic production mode to carry out the above-mentioned process processing. Most of them are stand-alone layouts with separate stations, which occupy a large area, and the processing parts need to be transported between each station, resulting in low production efficiency. , requires high labor costs, and the processing accuracy is low, resulting in a high rate of defective processing
