Abstract

The invention relates to a rapid film wrapping system of a battery electrode group. The system comprises an unreeling device, a film unfolding device, a cutting device and a film wrapping device. Theunreeling device comprises an unreeling mechanism, a positioning mechanism installed on one side of the unreeling mechanism and used for positioning a film end portion, and a transverse cutting mechanism installed on one side of the positioning mechanism. The film unfolding device comprises a guide mechanism, an adsorption mechanism installed on the guide mechanism and performing adsorption on thefilm end portion of the positioning mechanism, and a hauling mechanism used for driving the adsorption mechanism and the film end portion to move along the guide mechanism to unfold a film. The cutting mechanism comprises cutting positioning mechanisms installed on the front side and the rear side of the guide mechanism, and a driving mechanism used for driving the cutting positioning mechanismsto cut the unfolded film at regular intervals. The film wrapping device comprises a material pushing mechanism and a film wrapping mechanism, the material pushing mechanism is used for pushing a to-be-wrapped electrode group to move along the film wrapping mechanism, and cooperating with the film wrapping mechanism to finish the film wrapping. The rapid film wrapping system solves the problems oflow efficiency of the electrode group film wrapping, the difficulty of achieving automation, and low quality of the film wrapping.

Description

technical field [0001] The invention relates to the technical field of lead-acid battery electrode group coating equipment, in particular to a battery electrode group rapid coating system. Background technique [0002] The operation method of the traditional battery lamination machine is likely to cause quality problems such as diaphragms or plates in the pack, uneven height, and dust accumulation on the platform, which not only affects the work efficiency, but also affects the quality of the battery. Due to the occurrence of the two important quality unqualified items of internal electrode plate false welding and short circuit, a layer of film will be wrapped on the electrode group. In the battery industry, the coating operation of the electrode group is generally adopted on a simple platform and completely relies on manual labor. For encapsulation, the necessary tools are lacking. [0003] Authorized notification number CN201520895976.X is a Chinese utility model patent, ...
