A support device for bus bar welding

Abstract

The invention relates to an auxiliary tool for welding of photovoltaic components, which has the effect of tightly fixing bus bars. The invention discloses a support device for bus bar welding, comprising a base, on which a backing plate for supporting the bus bar is arranged, and a plurality of suction pads located directly under each bus bar are provided on the backing plate The base is provided with a plurality of electromagnets that are fitted and inserted into the corresponding adsorption holes, the base is provided with a power supply for uniformly supplying power to the electromagnets, the backing plate is detachably connected to the base, and the top of the electromagnet is flush with the top surface of the backing plate. With the cooperation of the electromagnet and the bus bar made of tinned copper sheet, the stable fixing of the bus bar is realized and the welding accuracy is ensured.

Description

technical field [0001] The invention relates to an auxiliary tool for welding of photovoltaic modules, and more particularly, to a support device for welding of bus bars. Background technique [0002] The solar cell is an important part of the solar cell module. It is formed by connecting a plurality of solar cells through welding strips. There are many welding strips parallel to the surface of the cell, and the ends of the welding strip are set outside the two sides of the cell. , the sides of the two sides are provided with a bus bar and the welding strip are welded and connected, and the current is collected through the welding strip and the bus bar. Usually manual welding is used. Due to the low efficiency of manual welding, automatic welding machines have been developed. However, in the process of automatic welding, there is no clamping device in the process of welding the bus bar with a soldering iron tip. The welding position is misaligned, which affects the welding ...

AI Technical Summary

Problems solved by technology

Manual welding is usually used. Due to the low efficiency of manual welding, automatic welding machines have been developed. However, in the process of automatic welding, there is no clamping device in the process of welding bus bars with soldering iron tips, and bus bars are prone to shift. Therefore, often Inaccurate welding position will affect the welding quality. In addition, in order to ensure the quality of solar cells, users and manufacturers have relatively strict quality regulations on the welding quality of bus bars, requiring that the welding quality be dense and firm, and the evaluation of whether the welding is firm or not One indicator is the size of the weld scar on the back of the bus bar. It is generally believed that the obvious and regular weld scar on the back of the bus bar is a sign of good welding quality.
