Caliper rule for regulating height of base plate of solder strip of solar cell welder

Abstract

The invention discloses a caliper rule for regulating the height of base plates of solder strips of a solar cell welder. The caliper rule comprises a main rule and a horizontal rule which slides up and down along the main rule and can be locked, wherein a dividing rule for measuring movement displacement of the horizontal rule is arranged on the main rule; and when the height of the base plates of the solder strips of the welder is regulated by using the caliper rule, one end of the main rule is fixed at a proper position of the welder, the horizontal rule moves up and down along the main rule, and according to the requirement of a welding process, the horizontal rule is regulated to a proper scale of the dividing rule and then is locked, and finally, the base plates of the solder strips are regulated so that upper surfaces of the base plates support against the lower surface of the horizontal rule, therefore, the welding heights of the base plates of the solder strips can be rapidly and accurately determined, the regulating efficiency is increased, and the base plates of the solder strips can be positioned in the same horizontal plane, therefore all support points of a welded solar cell are positioned on the same horizontal plane, open welding, leakage welding and other phenomena of the solar cell in a welding process are reduced, and the production quality of the solar cell is improved.

Description

technical field [0001] The invention relates to the technical field of measuring tools, in particular to a caliper for adjusting the height of a backing plate of a solar cell sheet welding machine. Background technique [0002] Solar photovoltaic modules include several solar cells and laminated components. Since the current and voltage of a single solar cell are relatively small, generally several solar cells are connected in series to obtain a high voltage, and then connected in parallel to obtain a high current, and then output through a diode. . [0003] The series connection of solar cells is generally realized by string welding. In the prior art, a welding machine is usually used to realize the welding of each solar cell in the solar cell string welding process. For example, a DF5 welding machine is a typical solar cell in the prior art. Equipment for welding component cells. [0004] When using a welding machine to weld solar cells, the following method is usually u...

Problems solved by technology

[0006] When the above-mentioned adjustment method is used to adjust the backing plate of the ribbon, due to the inaccuracy of the estimated height value, problems such as open welding, missing welding, and debris often occur during the welding process of solar cells, and repeated adjustments are required, which takes a long time time, which seriously affects the production quality and output of solar cells in the workshop
