[0002] With the development of the solar photovoltaic industry, the trend of thinning cells is becoming more and more obvious. Thinning cells not only effectively reduces material consumption, but also the flexibility of silicon wafers reflected by thinning also brings more possibilities to the battery and component ends. Due to the trend of thinning cells, when cells are transferred from one processing link to another and transported in stacks, static electricity often exists between the stacked cells, causing the cells to adsorb each other, causing a series of risks such as fragments during transportation, which is not conducive to the operation of the next processing link. Individual cells need to be processed during the processing of the stringer. Therefore, how to efficiently and losslessly separate the stacked cells is a technical key.

[0014] 2.

The corrugated hose is pressed into a flat shape, leaving space for gas discharge and is not completely compacted. The port of the corrugated hose is inclined at 30 degrees to cooperate with the flattened port, so that the gas blown out from it forms a higher pressure and blows between the two battery cells, thereby facilitating better separation of the two adhered battery cells.
