Abstract

The invention relates to the technical field of battery production, and particularly discloses a piece breaking device and a piece breaking method. The piece breaking device comprises a base, a rotating plate, a first driving piece, a second driving piece and a piece breaking part. The base comprises a first support and a second support, the first support is used for fixing a piece to be broken, the rotating plate is rotationally connected to the first support, the first driving piece is arranged on the second support, the second driving piece is arranged on the second support in a sliding mode, connected with the output end of the first driving piece and driven by the first driving piece to move in the longitudinal direction of the second support, one end of the piece breaking part is fixedly connected with the output end of the second driving piece, and the other end of the piece breaking part is rotationally connected with the rotating plate; and the piece breaking part is driven by the second driving piece to move in the longitudinal direction of the second support, and the output end of the second driving piece can stretch out and draw back in the longitudinal direction of the second support relative to the body of the second driving piece, so that the problems of breakage, subfissure and fragmentation generated when the scribed cell is broken can be solved, and the fragmentation rate of the cell is reduced.

Description

technical field [0001] The invention relates to the technical field of battery production, in particular to a breaking device and a breaking method. Background technique [0002] At present, the size of the cells of traditional solar modules is large and the power is low. Therefore, small cell components have appeared on the market. The resistance of the produced battery pack is reduced. [0003] When making small cells, a dicing machine is often used to cut the cell. When cutting the cell, the cell is usually not completely cut off, but a deep groove is cut on the cell and a layer is reserved. The very thin groove bottom wall forms a cutting seam, so that the cell sheet is cut into two parts without being completely cut off, and the cell sheet cut into two parts is connected through the groove bottom wall of the cutting seam. This cutting method can ensure that the cut cells will not be short-circuited, because during laser cutting, the laser beam will melt the crystallin...
