Problems solved by technology

[0003] The traditional method of processing lithium battery pole pieces is usually to directly use die-cutting to produce and process pole pieces, but this method similar to metal processing is not suitable for battery pole pieces with soft materials and thin thickness. During die-cutting, due to the continuous pulling and blanking, the edge of the pole piece is prone to wear and tear, and the edge of the battery pole piece will be folded, and the number of burrs on the edge of the pole piece will be increased; in order to solve the problems existing in the pole piece processing Problem, there is an urgent need for an intelligent all-in-one device for die-cutting and stripping of lithium battery pole pieces

Abstract

The invention relates to the field of pole piece processing, in particular to a lithium battery pole piece die cutting and slitting intelligent integrated device. The technical problem to be solved is to provide the lithium battery pole piece die cutting and slitting intelligent integrated device. According to the technical scheme, the lithium battery pole piece die cutting and slitting intelligent integrated device comprises a die cutting system and the like; a storage battery is installed on the rear side of a control screen and fixedly connected to a bottom frame. According to the invention, the lithium battery pole piece is processed, the processing mode of continuous pulling and blanking in the traditional technology is abandoned, and combining the phenomena of edge abrasion and edge folding in the die cutting of the pole piece in the prior art, the processing mode of firstly slitting and then die cutting is carried out on the pole piece, so that the side stability of the pole piece during processing is improved, and the number of edge burrs is reduced while edge rolling is reduced; and meanwhile, the defect that in the prior art, the pole pieces are broken during blanking and collecting of the pole pieces is solved.

Description

technical field [0001] The invention relates to the field of pole piece processing, in particular to an intelligent integrated device for die-cutting and striping lithium battery pole pieces. Background technique [0002] Lithium batteries are a type of batteries that use lithium metal or lithium alloys as positive / negative electrode materials and use non-aqueous electrolyte solutions. [0003] The traditional method of processing lithium battery pole pieces is usually to directly use die-cutting to produce and process pole pieces, but this method similar to metal processing is not suitable for battery pole pieces with soft materials and thin thickness. During die-cutting, due to the continuous pulling and blanking, the edge of the pole piece is prone to wear and tear, and the edge of the battery pole piece will be folded, and the number of burrs on the edge of the pole piece will be increased; in order to solve the problems existing in the pole piece processing Problem, th...
