Abstract

The utility model relates to a pole piece rubberizing device which comprises a rubberizing mechanism, an adhesive tape feeding mechanism and a connection mechanism. The rubberizing mechanism comprises two rubberizing rollers which are oppositely arranged, and a pole piece to be rubberized can pass through the rubberizing mechanism and is conveyed forwards under the cooperation of the rubberizing rollers. The connection mechanism is arranged between the rubberizing mechanism and the adhesive tape feeding mechanism. When the rubberizing operation is executed, the adhesive tape feeding mechanism is used for providing the adhesive tape with preset length, and then the connecting mechanism is used for transferring the adhesive tape provided by the adhesive tape feeding mechanism to the surface of one rubberizing roller. With the continuous rotation of the rubberizing roller, the adhesive tape on the surface of the rubberizing roller can be attached to the surface of the pole piece under the rolling action of the rubberizing roller. Therefore, the pole piece rubberizing device can keep conveying the pole piece in the rubberizing process of the pole piece, and the pole piece does not need to stop conveying and wait for rubberizing, so that the production efficiency is improved.
