Abstract

The utility model discloses a grid solar battery sheet welding jig which comprises a grid battery sheet welding platform, a pressing mechanism and an infrared welding lamp. Solder strip containing grooves matched with welded bar-shaped solar battery main grid lines in terms of number and position are formed in the grid battery sheet welding platform. The pressing mechanism is in a frame shape and placed above the grid battery sheet welding platform. Pressing bars which correspond to the solder strip containing grooves in the grid battery sheet welding platform are arranged on the pressing mechanism. Multiple holes are formed in the pressing bars. The positions of the holes correspond to the welding positions of solder strips and bar-shaped solar batteries. The infrared welding lamp is arranged above the pressing mechanism and carries out welding on the solder strips and the bar-shaped solar batteries through the holes in the pressing bars. According to the grid solar battery sheet welding jig, the solder strips and the bar-shaped solar batteries are pressed tightly and are welded through the infrared welding lamp, the automation degree of the whole welding process is quite high and the problems existing in manual welding and an existing automatic welding device are effectively solved.

A kind of grid solar cell piece welding fixture
Technical field
The utility model belongs to technical field of solar utilization technique, particularly a kind of grid solar cell piece welding fixture.
Background technology
The welding major part of the cell piece in the production technology of current common crystalline silicon component completes by craft, and manual welding is mainly divided into single weldering and the series welding of cell piece.Single weldering is that interconnecting strip is welded on the main grid line of front negative pole of cell piece, during its welding, first welding applied to scaling powder and dry, again cell piece is placed into and on preheating table, is preheating to 50 degrees Celsius of left and right, then interconnecting strip is placed into the correct position of cell piece main grid line, make the center superposition of interconnecting strip and main grid line, and whole piece interconnecting strip is welded along a direction of main grid line with electric iron.Series welding is by the required electrical connection of the common crystal silicon component of formation that is one another in series through single cell piece welding.Complete manual welding manner operating efficiency is lower, and to the having relatively high expectations of operator, is difficult for the strict quality of controlling product.
Grid cell piece is that some strip solar cells that cut into by common crystal silicon battery are arranged according to a certain fixing spacing, and with conductive material, these strip cell is electrically connected and is formed.Different from common crystal-silicon battery slice, the width less (approximately several mm are to tens mm) of each strip solar cell, therefore mechanical performance is quite fragile, if weld and easily cause battery bar cracked with common artisan craftsmanship, secondly the efficiency of manual welding is quite low, is unfavorable for industrialized production, and owing to need to keeping strip cell specific distance each other, positioning precision during therefore to welding also has higher requirement, and manual welding is difficult to meet.Current cell piece automatic welding equipment can only compatibility be of a size of the common crystal silicon solar battery sheet of 125mm * 125mm or 156mm * 156mm, and some strip solar cells cannot be welded into a grid cell piece.
