Tab protection device of electrode film roll

The utility model discloses a pole lug protection device of an electrode film roll, which comprises a winding drum, a pole lug protection device and a pole lug protection device, the stopping assembly is arranged on the outer wall of the edge of the winding drum, the stopping assembly gradually extends outwards in the circumferential direction of the winding drum, and the side face, close to one side of the winding drum, of the stopping assembly is isolated from a tab of an electrode slice wound on the winding drum. According to the utility model, the end surface of a tab on a film roll formed by rolling an electrode plate can be protected, and external gouges or scratches are transferred to the stop component, so that the effect of preventing the end surface of the tab on the film roll from being gouges or scratches is realized; therefore, the situation that the end face of the film roll is damaged and materials are scrapped due to improper operation or external things can be completely avoided. 本实用新型公开了一种电极
