Description

Battery piece taking and placing device Technical Field The utility model relates to the technical field of solar cells, and particularly provides a cell picking and placing device. Background In the production process of the solar cell module, part of working procedures such as serial inversion and stacking and returning are needed to be manually interfered to take out the discharge cell sheet. When the battery piece is taken and placed, the surface of the battery piece is easily scratched, so that the performance and the reliability of the battery are obviously affected. Particularly, BC (Back Contact) modules, that is, solar modules adopting a back contact technology, are provided, wherein the positive and negative electrodes of the battery cells are designed on the back surface, the front surface is not provided with solder strips and grid lines, the back electrodes are generally in an interdigital finger structure or a matrix layout, the electrodes can be shielded or the subsequent operation can be influenced by taking the discharge cell from the back surface, and the blue film surface on the surface of the battery cells is easily scratched by taking the discharge cell from the front surface, so that the battery cells are very difficult to take and place. The current instrument of getting discharge cell piece is got through absorbing the cell piece and is put, reduces the risk to cell piece surface fish tail, but the volume of instrument is great, and needs to arrange the trachea and communicate with external air supply, leads to getting of cell piece to put the action limited, influences work efficiency. Accordingly, there is a need in the art for a new battery tab handling apparatus that addresses the above-described issues. Disclosure of utility model The utility model aims to solve the technical problems, namely the problem that a tool for manually taking the battery piece is inconvenient to use because of reducing the risk of scratching the battery piece.
