Multi-material-roll pole piece unwinding device

Abstract

The invention discloses a multi-material-roll pole piece unwinding device which comprises a roll preparing position, an unwinding position, a pole roll automatic bar code tearing device, a pole roll automatic roll exchanging device and a pole roll carrying mechanism, the roll preparing position and the unwinding position are close to each other, and hanging shafts used for hanging pole rolls extend out of the middle of the roll preparing position and the middle of the unwinding position. The automatic pole roll bar code tearing device is used for tearing bar codes of roll material heads of new pole rolls on the roll preparing position, and the automatic pole roll exchanging device is used for splicing the roll material heads of the new pole rolls with the bar codes torn and the roll material heads of old pole rolls above the roll unwinding position. The pole roll carrying mechanism is movably arranged between the roll preparing position and the roll unwinding position, and a conveying track for the pole roll carrying mechanism to move is arranged below the roll preparing position and the roll unwinding position. By means of the multi-material-roll pole piece unwinding device, the labor amount of workers can be greatly reduced, the machining efficiency is improved, and the one-person multi-machine control mode becomes possible.

Description

technical field [0001] The invention relates to the technical field of pole piece processing, in particular to a multi-roll pole piece unwinding device. Background technique [0002] In the production process of secondary batteries, the pole piece roll is usually supported on the drive roller, and a certain pulling force is applied to the unfolded end of the pole piece roll through the driving roller, so that the pole piece can continue to move in the direction where the drive roller is located. And participate in the subsequent processing process, but in the refueling process after a pole piece material is used up, it is often necessary for the staff to manually change the material, and then connect the joints of the two material reels together, the whole working process takes a long time , the efficiency is low, which seriously restricts the expansion of the "one person with multiple machines" control mode. Contents of the invention [0003] The purpose of the present i...
