Supporting device used for bus bar welding

Abstract

The invention relates to a photovoltaic module welding auxiliary tool which has the effect of tightly fixing bus bars, and discloses a supporting device used for bus bar welding. The supporting devicecomprises a base, a base plate used for supporting bus bars is arranged on the base, multiple adsorption holes located under the bus bars are formed in the base plate, multiple electromagnets inserted into the corresponding adsorption holes in an attached manner correspondingly are arranged on the base, a power supply for supplying power to the electromagnets in a unified manner is arranged on the base, the base plate is detachably connected with the base, and the top ends of the electromagnets are flush with the upper surface of the base plate. By means of cooperation of the electromagnets and the bus bars made of tinned copper sheets, stable fixation of the bus bars is achieved, and welding accuracy is guaranteed.

Description

technical field [0001] The invention relates to a photovoltaic module welding auxiliary tooling, more specifically, it relates to a supporting device for bus bar welding. Background technique [0002] The battery sheet is an important part of the solar cell module. It is formed by connecting a plurality of solar cells through welding ribbons. There are multiple welding ribbons arranged in parallel on the surface of the battery sheet, and the ends of the welding ribbons are set outside the two sides of the battery sheet. , the two sides are provided with a bus bar and welded to the welding strip, and the current is collected through the welding strip and the bus bar. 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 Ina...

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.
