1. An electrode plate processing device, comprising: an electrode plate conveying mechanism configured to convey an electrode plate, the electrode plate comprising a coated region coated with an active material layer and an exposed foil region uncoated with the active material layer;
a cutting mechanism disposed opposite to the electrode plate and configured to cut the exposed foil region of the electrode plate to form a tab;
a waste adsorption mechanism entirely disposed downstream of the cutting mechanism along a conveying direction of the electrode plate, wherein the waste adsorption mechanism comprises an active driving roller, a driven support roller, and a conveyer belt that is coupled to the active driving roller and the driven support roller in a transmission way, and the conveyer belt is driven by the active driving roller to rotate and configured to provide a negative pressure to a waste edge produced during the cutting of the electrode plate so as to adsorb the waste edge, wherein a rotational speed of the active driving roller is greater than a conveying speed of the electrode plate conveying mechanism; and
an auxiliary roller arranged upstream of the cutting mechanism and configured to support the exposed foil region.
