Device for manufacturing battery pole piece and method

Abstract

The invention discloses a device for manufacturing battery pole pieces, comprising a pole piece feeding module, a lug welding module, a rubberizing module and a polar piece receiving module sequentially arranged along the conveying direction of the pole pieces; the device further comprises a first drive module, a first buffer memory module and a second drive module; wherein the first drive moduleis arranged between the lug welding module and the rubberizing module and is used to drive the polar pieces to be output from the polar piece feeding module and pass through the lug welding module; the first buffer memory module is arranged between the first drive module and the rubberizing module for caching the polar pieces; the second drive module is arranged between the rubberizing module andthe polar piece receiving module for driving the polar pieces to pass through the rubberizing module to be output to the polar piece receiving module. The invention further discloses a method for manufacturing the polar pieces; with the device and the method of the invention adopted, nonmatching of polar piece processing time of different processes in the process of manufacturing the polar piecescan be resolved, thus greatly improving efficiency in manufacturing the polar pieces.

Description

technical field [0001] The invention relates to the manufacture of batteries, in particular to a manufacturing device and method for battery pole pieces. Background technique [0002] According to the known production process of the battery pole piece, first weld the tab on the unrolled pole piece, then paste the tab protection tape up and down on the position of the pole piece, and then paste the tape on the blank part of the pole piece, and finally close the However, in the whole production process, the man-hours for the processing of the pole pieces in each process do not match, and the known technology only realizes the conveyance of the pole piece by a pole piece driving device, for example, arranged at the winding end of the pole piece , although the pole piece transport buffer can be set before each process, but using one drive device to control the pole piece transmission between multiple different processes cannot solve the problem of mismatching working hours of ea...
