Zusammenfassung: | The invention relates to a lithium ion battery pole piece rolling wrinkle eliminating device and eliminating method.The device comprises wrinkle eliminating mechanisms oppositely arranged on the two sides of a pole piece wrinkle prone area in a pressing mode, and each wrinkle eliminating mechanism comprises a pressing wheel, a belt wheel and a transmission belt arranged between the pressing wheel and the belt wheel in a sleeving mode; wherein the transmission belt is pressed on the pole piece wrinkle easy-to-occur area through the pressing wheel and/or the belt wheel and elastically deforms; and the belt wheel is used as a driving wheel and is arranged on the front side of the pressing wheel along the moving direction of the pole piece. Compared with the prior art, the rolling device can effectively prevent the pole piece from generating wrinkles due to the difference of the extension amount of the film coating area and the extension amount of the blank area in the rolling process, so that the large-scale con |
