Abstract

The invention discloses a battery piece splitting device and a battery piece splitting method. The battery piece splitting device comprises a splitting laser and a cooling device; the splitting laseris arranged to be capable of moving and can emit laser light to cut a battery piece; and the cooling device is provided with a cooling spray head capable of moving along with the splitting laser, andthe cooling spray head can spray cooling liquid to the cutting portion of the battery piece by the splitting laser. According to the technical scheme, in the process that the splitting laser emits laser light to the battery piece so as to cut the battery piece, the cooling spray head sprays the cooling liquid to the cutting portion of the battery piece, cooling of the battery piece can be effectively achieved, and then the problem that the battery piece is damaged due to the fact that the temperature of the cutting portion is too high is avoided.

Description

technical field [0001] The invention belongs to the technical field of photovoltaic cell production, and in particular relates to a cell splitting device and a cell splitting method. Background technique [0002] In the production process of photovoltaic cells, there is a process of dividing a whole battery sheet into at least two pieces and connecting the divided battery pieces to form a battery string. [0003] At present, there are two main methods of dividing the entire battery sheet. One is to first scribe a laser line on the battery sheet, and then use a sheet breaking device to mechanically break the battery sheet along the scribing line. This method will cause the cell Melting is formed in the scribed area, and it is easy to cause damage to the cell when it is mechanically broken; [0004] Another method is to use a continuous laser to directly cut the battery sheet, but in this method, the temperature of the laser at the cutting place is often relatively high durin...
