ROLLING APPARATUS AND PROCESSING DEVICE

Provided are a rolling apparatus and a processing device, which are used for rolling an electrode plate. The rolling apparatus includes a first roller and a second roller, where the first roller and the second roller are disposed at two sides of the electrode plate in a thickness direction of the electrode plate. The first roller is provided with a plurality of recessed portions, the electrode plate includes a plurality of insulation coating layer regions and a plurality of tabs, and in a projection of the electrode plate in the thickness direction, at least part of a projection of the insulation coating layer region and a projection of the tab are located within a projection of the recessed portion. The rollers deflect under a large rolling pressure.
