Abstract: A device for repairing burrs of an electrode plate is provided, which includes a plurality of shaping rollers, wherein a shaping surface is formed on an outer surface of each of the shaping rollers, and along a conveying direction of an electrode plate, included angles between the plurality of shaping surfaces and a surface of the electrode plate decrease in sequence. The device for repairing burrs of an electrode plate gradually decreases the angle between the burrs and the electrode plate until the burrs are flattened, and the end-surface burrs are finally transformed into flat-surface burrs, thereby reducing the safety risk of batteries.
