Problems solved by technology

[0003] The welding strips required for this single-sided dense grid line battery string have the following characteristics: the welding strips connected to adjacent battery sheets on adjacent grid lines need to be arranged alternately, and the short welding strips welded on the battery sheets at both ends of the battery string are connected to the adjacent grid. The rest of the ribbons on the line should also be misplaced for a certain distance in the length direction. At present, there is no ribbon-making and ribbon-laying equipment developed for this ribbon arrangement in the market. Under the premise of ensuring a certain production efficiency, each component Manufacturers urgently need automation equipment to solve these technical problems

Embodiment 1

[0029] figure 1 As well as image 3 and Figure 5 It is the first embodiment of the present invention. Taking the battery string of 17 grids as an example, when the number of batteries is 11 tablets:

[0030] Step 1: Nine that the welding bands that need to be welded on the 17 -grilled battery tablet are pulled out of the right from the left welded belt on the left on the left. Cut off, and keep the welding bands in a parallel way;

[0031] Step 2: Then pull the remaining welding bands according to the required length required by a single battery string as the second welding belt group 20 from the right welding belt to the left, and keep the welding bands in a parallel way. The steps are parallel. The welding band from Erlu is interspersed between the welding bands placed in step one, and placed in the direction of the welding zone;

[0032] Step 3: Put the first short welding band with a long welding band of the first welding belt 10 in the length of the length of the length of th...

Embodiment 2

[0036] figure 2 As well as Figure 4 and Image 6 It is the second embodiment of the present invention. Taking the battery string of 17 grids as an example, when the number of batteries is 12 tablets:

[0037] Step 1: Nine that the welding bands that need to be welded on the 17 -grilled battery tablet are pulled out of the right from the left welded belt on the left on the left. Cut off, and keep the welding bands in a parallel way;

[0038] Step 2: The other total length of the short welding band is used as the required length required for a single battery string as the second welding belt group 20 to pull and cut off from the right welding roll to the left, and keep the welding bands in a parallel way in parallel. Place, the welding band pulled out in step two is interspersed between the welding bands placed in the step first, and placed in the direction of the welding zone.

[0039]Step 3: Put the first welding zone 10 according to the long welding band 40 and 1 of the length of...

Abstract

The present invention provides a method for preparing a ribbon for single-sided welding of dense grid solar cell strings. The method includes a step of bidirectionally drawing the ribbon, a step of breaking the ribbon at a fixed point, and a step of spacing, and is used for preparing the required welding tape for the single-sided dense grid battery string. The long welding strip with length B is connected between adjacent cells, the first short welding strip with length C and the second short welding strip with length D are welded to the single cell at both ends of the battery string. The long welding strip is staggered from the first short welding strip and the second short welding strip, and the method can prepare all the welding strips required by the whole battery string at one time.

Description

Technical field [0001] The invention involves the tape -band method of welding bands, especially the welding zone preparation method of a single -sided welding dense grille solar cell skewers. Background technique [0002] Since the development of solar battery films, the dense grid components have been widely used in individual component manufacturers, but the battery films used in traditional dense grid components are double -sided battery surfaces. The welding belt needs to be welded on the front and back of the adjacent battery surface to complete the battery to complete the battery. String welding. [0003] The welding belt required for this single -sided dense grid line battery string has the following characteristics: the welding belt connected to the adjacent battery piece on the neighboring grid line needs to be staggered. The remaining welding bands on the line must also be arranged at a certain distance in the direction of length. At present, there are no bands and clo...
