Description

Technical Field

[0001] This utility model relates to the field of battery string production technology, specifically to a spacing drying mechanism. Background Technology

[0002] The commonly used solar cells in photovoltaic strings are half-cell, three-quarter-cell, or four-quarter-cell cells. Compared to a full-cell cell, these cells have lower current draw, reducing power loss in the string. Half-cell, three-quarter-cell, or four-quarter-cell cells, as well as other multi-cell cells, are created by laser-cutting a full-cell cell. In one non-destructive laser-cutting technique, water is sprayed onto the cut lines of the full-cell cell to assist in the cutting process, resulting in water-coated edges on the surface of the resulting cells. Direct lamination technology uses hot-melt adhesive film to fix solder ribbons to the surface of the cells to produce strings. When the cell surface is wet, the hot-melt adhesive film melts and adheres to the cell. However, the water affects the adhesion between the hot-melt adhesive film and the cell, reducing the quality of the string. Utility Model Content

[0028] like Figure 1 As shown, the segmented solar cell 10 is a two-segment solar cell. After the entire solar cell is laser-cut, water is sprayed onto the cutting track for cooling, causing the entire solar cell to be divided into two segments 10 along the cutting track. The water spray area on the cutting track is divided into two parts, which are the water-cooling treatment areas 11 on the two segments 10. Figure 2 As shown, the segmented solar cell 10 is a three-segment solar cell, formed by dividing a whole solar cell into three parts along two cutting lines. The water-cooling treatment area 11 is located at the junction of the long sides of any two adjacent segmented solar cells 10. Figure 3 As shown, the segmented solar cell 10 is a four-segment solar cell, formed by dividing a whole solar cell into four parts along three cutting lines. The water-cooling treatment area 11 is located at the junction of the long sides of any two adjacent segmented solar cells 10. Figure 4 As shown, the segmented solar cell 10 is a four-segmented solar cell, formed by cutting a whole solar cell into two segments and drying them, and then dividing each of the two segments into two parts along the cutting groove. The water-cooling treatment area 11 is located at the junction of the long sides of the first segmented solar cell 10 and the second segmented solar cell 10, and the third segmented solar cell 10 and the fourth segmented solar cell 10. For four-segmented, five-segmented, or six-segmented solar cells, which are formed by cutting a whole solar cell into four or more parts, they can be formed by cutting the whole solar cell in one go; or they can be formed by cutting the whole solar cell in several stages, that is, first cutting the whole solar cell into several segments 10 and drying them, and then cutting the several segments 10 into the corresponding number of segments.

[0030] Each adsorption element 30 is used to adsorb one segmented battery cell 10 and separate two adjacent segmented battery cells 10 by a preset distance. The drying element is used to dry the water-cooled treatment area 11 on the segmented battery cell 10, so that the surface of the segmented battery cell 10 remains dry.

The heating rod 42 is embedded in the mounting base 41. The mounting base 41 is fixed to the mounting plate 20 or the adsorption component and is located below the mounting plate 20. Preferably, along a direction parallel to the long side of the segmented battery cell 10, two rows of air blowing holes 411 are provided on the mounting base 41. The two rows of air blowing holes 411 blow air into the water-cooling treatment areas 11 adjacent to two adjacent segmented battery cells 10. The gas is heated by the heating rod 42 before flowing out of the air blowing holes 411. The two rows of air blowing holes 411 are inclined, and the blown gas flows directly into the water-cooling treatment area 11 to accelerate drying.
