Problems solved by technology

[0002] In the manufacturing process of solar cell modules, the welding ribbon welds the adjacent battery sheets to form a battery string. In order to improve the conversion rate of the battery sheet, there are more and more grid lines of the battery sheet, and the corresponding welding ribbon is getting thinner and thinner. When the cut off When the ribbon is placed on the surface of the battery and is transmitted synchronously with the battery, the position of the ribbon and the grid line of the battery is prone to shift, which will cause the exposed area of ​​the ribbon to exceed the range, and ultimately affect the welding quality of the battery string

Abstract

The invention relates to solar battery cell series welding equipment and a series welding method. The series welding equipment comprises a machine frame, a conveying mechanism, a battery cell carryingmechanism used for conveying battery cells to be welded to the conveying mechanism, a solder strip uncoiling mechanism, a solder strip pulling mechanism used for pulling solder strips, a solder stripcutting mechanism used for cutting off the solder strips, a welding mechanism used for welding the solder strips onto the corresponding battery cells, and a solder strip pressing mechanism. The solder strip pressing mechanism is used for tightly pressing the solder strips conveyed onto the upper surfaces of the battery cells to battery cell grid lines opposite to the solder strips. By means of the solar battery cell series welding equipment, relative movement of the solder strips and the battery cells can be avoided, the welding precision of the solder strips and the battery cells is effectively improved and the defective rate is lowered.

Description

technical field [0001] The invention relates to the technical field of solar cell sheet manufacturing equipment, in particular to a solar cell string welding equipment and a string welding method. Background technique [0002] In the manufacturing process of solar cell modules, the welding ribbon welds the adjacent battery sheets to form a battery string. In order to improve the conversion rate of the battery sheet, there are more and more grid lines of the battery sheet, and the corresponding welding ribbon is getting thinner and thinner. When the cut off When the ribbon is placed on the surface of the cell and is conveyed synchronously with the cell, the position of the ribbon and the grid line of the cell is prone to shift, which will cause the exposed area of ​​the ribbon to exceed the range, and ultimately affect the welding quality of the battery string. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the ...
