Abstract: An electrode plate processing device is provided. The electrode plate processing device includes: an electrode plate conveying mechanism configured to convey an electrode plate; a cutting mechanism disposed opposite to the electrode plate and configured to cut the electrode plate to form a tab; and a waste adsorption mechanism disposed downstream of the cutting mechanism along a conveying direction of the electrode plate. The waste adsorption mechanism includes 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. The conveyer belt is driven by the active driving roller to rotate and configured to provide an adsorption force to a waste edge produced during the cutting of the electrode plate so as to adsorb the waste edge.

Abstract: The present disclosure relates to an electrode plate processing device. The electrode plate processing device includes: an electrode plate cutting mechanism having a cutting position; and an electrode plate rolling mechanism, through which an electrode plate passes. The electrode plate rolling mechanism includes a first roller and a second roller. The first roller has a vacuum adsorption zone for adsorbing a waste edge of the electrode plate. The cutting position is provided in upstream of the vacuum adsorption zone along a conveying direction of the electrode plate processing device.
