A vibration gap is provided between the battery slice and the surface limiting component, and the battery slice has space during vibration. When in use, the rotating component drives the rotating base plate to rotate at an angle (also can be understood as flipping), so that multiple battery slices are tilted toward a side finisher, and multiple battery slices can be moved by their own weight to improve the finishing effect. While rotating, the vibrating table vibrates to continuously form a gap between multiple battery pieces, which has a separation effect, thereby reducing the contact fit of the battery pieces. During rotation, the battery pieces move more by their own weight, and the other three sides are arranged The device is moved closer to the center of the cross to achieve the finishing effect, the vibration of the shaking table is maintained, and the surface scratch rate during the finishing process of the battery sheet is reduced.
