Description

Technical Field

[0001] The present application belongs to the technical field of photovoltaic cell string production, and in particular relates to a cell sheet regularization device and a glue application device. Background Art

[0002] In the low-temperature welding process of battery strings, there is a process of printing glue dots on the surface of battery cells using a silk screen device. Before printing glue on battery cells, the position of the incoming battery cells needs to be regularized by a regularization device to ensure that the glue dots can be printed to the specified position of the battery cells. Conventional battery cell printing glue uses single-piece printing glue (i.e., one piece is printed at a time), and there is only one set of printing mesh holes on the printing glue screen. Therefore, the conventional regularization device only needs to regularize one battery cell at a time. However, when it is necessary to print glue on two battery cells at the same time, there are two sets of printing mesh holes on the printing glue screen, and the relative positions of the two sets of printing mesh holes are fixed. This requires that the two battery cells need to be regularized at the same time, and the spacing between the regularized cells needs to meet the predetermined value to ensure the quality of the printing glue after the two battery cells are printed at the same time. Obviously, the existing regularization device cannot meet the above-mentioned regularization requirements for the two battery cells. Utility Model Content

[0065] In the low-temperature welding process of battery strings, there is a process of printing glue dots on the surface of battery cells using a silk screen device. Before printing glue on battery cells, the position of the incoming battery cells needs to be regularized by a regularization device to ensure that the glue dots can be printed to the specified position of the battery cells. Conventional battery cell printing glue uses single-piece printing glue (i.e., one piece is printed at a time), and there is only one set of printing mesh holes on the printing glue screen. Therefore, the conventional regularization device only needs to regularize one battery cell at a time. However, when it is necessary to print glue on two battery cells at the same time, there are two sets of printing mesh holes on the printing glue screen, and the relative positions of the two sets of printing mesh holes are fixed. This requires that the two battery cells need to be regularized at the same time, and the spacing between the regularized cells needs to meet the predetermined value to ensure the quality of the printing glue after the two battery cells are printed at the same time. Obviously, the existing regularization device cannot meet the above-mentioned regularization requirements for the two battery cells.
