[0002] A solar cell group is a component composed of multiple single solar cells interconnected and packaged. The heat sealing process of the solar cell group is to put the stacked solar cell components into the laminator, and vacuum the air in the components. , and then heat to melt the EVA to bond the battery, glass and back sheet together. However, the existing laminator has a single function and cannot quickly adjust the lamination thickness. The pressure plate needs to be replaced when the solar battery pack exceeds the specification. The vacuum component of the existing laminator is designed in the heating box. EVA melting is easy to block the pores, resulting in residual air in the box, which affects the quality of the product.

The invention discloses a heat sealing device for processing a solar battery pack, which comprises a base, a heat sealing thickness adjusting assembly, a vacuumizing assembly, a bracket, a bottom heating box, a middle heating box, a top cover and a connecting block, wherein the heat sealing thickness adjusting assembly comprises a hydraulic cylinder, a first connecting shaft, a first connecting rod, a second connecting rod, a second connecting shaft, a third connecting rod, a third connecting shaft and a through groove, and the vacuumizing assembly comprises a pressing plate, an elastic pressing block, a fourth connecting rod, a limiting block, a spring, a first limiting groove, a first pipeline, a sealing ring, a second limiting groove, a mounting groove, a second pipeline and a flange plate. Compared with an existing laminating machine, the heat sealing thickness adjusting assembly is designed, the heat sealing thicknesses of multiple sets of heating boxes can be rapidly and synchronously adjusted, the heat sealing device is suitable for heat sealing processing of large-batch solar battery packs, and the designed vacuumizing assembly can avoid air hole blockage and prevent air residues in the box bodies.
Description
technical field [0001] The invention relates to the technical field of solar cells, in particular to a heat sealing device for processing solar cell groups. Background technique [0002] A solar cell group is a component composed of multiple single solar cells interconnected and packaged. The heat sealing process of the solar cell group is to put the stacked solar cell components into the laminator, and vacuum the air in the components. , and then heat to melt the EVA to bond the battery, glass and back sheet together. However, the existing laminator has a single function and cannot quickly adjust the lamination thickness. The pressure plate needs to be replaced when the standard solar battery pack is used. The vacuum component of the existing laminator is designed in the heating box. The melting of EVA will easily block the air holes, resulting in residual air in the box and affecting the quality of the product. Contents of the invention [0003] The object of the presen...
