Method and system for processing columnar lithium battery

Abstract

The invention discloses a method and system for processing a columnar lithium battery. The system comprises an electrode processing system, a master assemblage system and a sleeve packaging system. In the method, a guide pin is delivered into a flat delivery rail and a push pin rail in sequence to realize alignment and then enters a pre-punching hole in a nail pin region for finishing the pin nailing; after a piece of foil paper is subjected to primary foil drawing, flattening, secondary foil drawing and foliation, a tail end of the withdrawn guide pin is coiled and simultaneously the foil paper is laminated, cut, cemented and output; the fixed connection and packing of an aluminum shell and the positioned guide pin can be realized by program control so as to form a battery main structure; and a ruler sleeve is embedded into a tubular colloid in accordance with the setting of a control device, and the displacement and the movement period are calibrated to control a packaging device so as to realize end sealing. By adopting the technical scheme, resources such as materials and the like are saved, a large amount of processing time can be saved, and the production efficiency of a product is improved; and the external dimension of the product is set flexibly, technological parameters are transformed quickly in accordance with different application fields, and the application range of the product is broadened maximally.

Description

technical field [0001] The invention relates to the technical field of lithium batteries, in particular to a processing method and system for a cylindrical lithium battery.

AI Technical Summary

Problems solved by technology

At present, the traditional processing of cylindrical lithium batteries mostly uses a single machine to independently process parts and manually pick up materials, resulting in incoherent processing procedures and a single operation of the processing machine, which greatly reduces the scale and coupling of parts, and cannot be matched normally resulting in more defective products. And the quality of the finished product is not high, thus limiting its scope of use

Manual operations in multiple links cannot achieve automatic control of production, which makes the processing process complicated, the production cycle is too long, increases the waste of raw materials and other resources, and increases the production cost
