Automatic roll replacing and strip connecting system for battery pole pieces

Abstract

The invention discloses an automatic roll replacing and strip connecting system for battery pole pieces. The automatic roll replacing and strip connecting system comprises an unreeling machine and a strip connecting device. The unreeling machine is an automatic double-position unreeling machine. The automatic double-position unreeling machine comprises a first working position and a second working position, wherein the second working position is the position where a strip roll is placed when the automatic double-position unreeling machine operates normally. The position of the strip roll at the first working position and the position of the strip roll at the second working position are changed through large rotation. The strip connecting device is arranged on the side face of the second working position of the unreeling machine. The unreeling machine and the strip connecting device are both connected with an automatic control system. According to the automatic roll replacing and strip connecting system, roll replacement and strip connection are integrated, and roll replacement and strip connection of the battery pole pieces can be automatically achieved without a halt, so the automation degree of production and the production efficiency of the battery pole pieces are greatly improved, the labor intensity is lowered, and the product quality is improved.

Description

technical field [0001] The invention relates to a production device for battery pole pieces, in particular to a battery pole piece automatic strip-connecting and roll-changing device. Background technique [0002] In the production process of battery pole pieces, single-station unwinding is generally used. When the tape is used up, the overall equipment must be shut down, and the roll is changed manually. After the roll change is completed, the two rolls are spliced. The initial end of the new tape is provided with a bonding strip, and the end of the original tape is connected to the initial section of the new tape through the bonding strip. This method of changing rolls and connecting tapes causes a delay in downtime, reduces production efficiency, is not convenient for automatic operations, consumes a lot of manual labor, and has poor controllability of product quality. [0003] Chinese patent CN202542537U discloses an automatic roll-changing and unwinding machine, includ...
