Automatic core closing mechanism for power battery

Abstract

The invention discloses an automatic core closing mechanism for a power battery. The automatic core closing mechanism for the power battery comprises a battery cell closure mechanism, a lifting base,a cover plate positioning and shaping mechanism and battery cell pressing mechanisms, wherein the battery cell closure mechanism is mounted on the lifting base in an up-and-down movable manner, and comprises two battery cell supporting plates and a motor used for driving the two battery cell supporting plates to be opened and closed; the cover plate positioning and shaping mechanism is arranged between the two battery cell supporting plates; the battery cell pressing mechanisms are arranged at the lower ends of the two battery cell supporting plates; the battery cell pressing mechanisms comprise battery cell chucks used for being fixed at battery cell positions on the battery cell supporting plates. The automatic core closing mechanism disclosed by the invention is reasonable in design andconvenient to operate, the manual cost can be decreased, and the product quality and the capacity are improved.

Description

technical field [0001] The invention relates to the technical field of lithium battery production, in particular to an automatic core-closing mechanism for a power battery. Background technique [0002] At present, most of the metal-shell power batteries need to be stacked and closed after pairing with AB cells, and put into steel or aluminum shells after ultrasonic welding. For the difference in the welding process of the positive and negative electrodes of the battery, ultrasonic welding of the positive electrode and resistance storage of the negative electrode It can be welded, and the AB cells need to be placed flat and welded together before they can be put into the shell. At present, most of the cells are folded manually, but the force used for manual folding is unstable and uncontrollable, and it is easy to The tabs cause damage, and the production capacity is not high, which cannot meet the needs of the industry. Contents of the invention [0003] Aiming at the ab...
