Their structure and production process have been finalized, and the products have been widely used in space and on the ground. This type of solar cell uses high-purity single crystal silicon rods as raw materials. In order to reduce production costs, solar cells used on the ground now use solar-grade single crystal silicon rods, and the material performance indicators have been relaxed.

The cutting line depth of some battery cells is too shallow, which makes it difficult to break the battery cells apart when the two breaking blocks are driven to rotate in opposite directions.

[0006] 2. Since the two electric cylinders need to be started at the same time to make the two racks mesh with the driving gears respectively, if the two electric cylinders are not started at the same time, the rotation angles of the two breaking blocks will be inconsistent, which will affect the breaking process.

[0014] As a further solution of the utility model: material receiving trays are arranged on both sides of the fixed block.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. In order to prevent the cutting line of the battery cell from being too shallow, insert the battery cell into the breaking groove on the breaking block, start the cylinder, and the output end of the cylinder drives the cutting knife to move and perform secondary cutting along the cutting line of the battery cell.
