The invention relates to the field of solar cell packaging process equipment, and discloses a packaging structure based on a crystalline silicon solar cell, the packaging structure comprises a workbench and a cell, the top of the workbench is provided with an openable upper cover box, and the bottom of the inner cavity of the upper cover box is provided with an air bag; the inner space of the workbench and the upper cover box is divided into an upper cavity and a lower cavity by the air bag, a sealing ring is arranged at the joint of the workbench and the upper cover box, and the battery piece is placed in the lower cavity of the workbench. Through the structural design that the two limiting transverse pipes are arranged in the lower cavity, one of the limiting transverse pipes is movable, and the limiting mechanisms are arranged at the tops and the bottoms of the two limiting transverse pipes correspondingly, the limiting mechanisms on the two limiting transverse pipes abut against a back plate and a glass substrate from the two sides of a battery piece correspondingly, and therefore the back plate and the glass substrate are limited; and the back plate, the tandem silicon wafer and the glass substrate are ensured not to be staggered and moved during the pressurizing period of the upper chamber, so that the lamination quality of the battery piece is ensured.
Description
technical field [0001] The invention relates to the field of packaging process equipment for solar cells, in particular to a packaging structure based on crystalline silicon solar cells. Background technique [0002] Solar cells can convert clean light energy into electrical energy. It has the advantages of high efficiency, low attenuation, and strong reliability. It has a wide range of applications. Most solar cells are crystalline silicon cells. Among them, crystalline silicon solar cells The packaging process includes the steps of single welding, string welding, lamination, editing, testing, framing, curing, cleaning, and testing. A vacuum laminator is required for the lamination and packaging of cells. [0003] When the existing solar cells are laminated and packaged, it is necessary to set a pad cloth on the workbench and the cover plate to catch the glue flowing down and prevent the glue from adhering to the airbags of the workbench and the cover plate. During the lam...
