Method for welding crystalline silicon solar energy assembly bus bar and interconnector

Abstract

The invention belongs to the manufacture field of a crystalline silicon solar energy assembly, in particular to a method for welding a crystalline silicon solar energy assembly bus bar and an interconnector. The method comprises the following steps: arranging a plurality of cell strings provided with the interconnectors, and causing the interconnectors on the end part of the cell string to tidily expose; arranging bus bars on two ends of arranged cell strings; contacting and connecting the bus bars with the exposed interconnectors to form a plurality of contact points; respectively connecting the positive electrode and the negative electrode of a high-frequency power supply with the interconnectors and the bus bars; forming a high-frequency current circuit by the high-frequency power supply, the interconnectors, the bus bars and the contact points; turning on the high-frequency power supply; controlling high-frequency current oscillation frequency to be more than 50kHZ; and cutting off the high-frequency power supply after the high-frequency power supply is turned on for 2-3 seconds to successively weld the interconnectors with the bus bars. The welding method has the advantages that skin effect generated by the high-frequency current is used for welding, product efficiency is improved, welding quality is good, and stability is high.

Description

technical field [0001] The invention belongs to the field of manufacturing crystalline silicon solar modules, in particular to a method for welding bus bars and interconnecting bars of crystalline silicon solar modules. Background technique [0002] In the manufacturing process of crystalline silicon solar cell components, interconnection bars and bus bars must be welded together. The welding of bus bars has a key impact on the production efficiency and quality stability of crystalline silicon solar cell components. At present, the bus bars of solar components The welding method is manual welding, and an electric soldering iron is usually used for manual welding, which has low production efficiency and poor quality stability. Contents of the invention [0003] The purpose of the present invention is to address the shortcomings of low production efficiency and poor quality stability of manual welding in the above-mentioned technology, and propose a welding method for bus ba...
