Infrared welding device for solar battery string

Abstract

The invention discloses an infrared welding device for a solar battery string. The infrared welding device for the solar battery string comprises a conveying mechanism, a heating platform, laid battery pieces and laid solder strips. A welding head lifting mechanism is installed on the corresponding upper portion of the conveying mechanism and provided with an infrared welding head. A lifting pressing pin mechanism is arranged on the lower portion of the infrared welding head. A vacuum negative pressure adsorption mechanism is arranged between the conveying mechanism and the heating platform. In this way, the battery pieces and the solder strips are laid on the conveying mechanism with the heating platform and conveyed to the welding position under the infrared welding head, and it is guaranteed that the pressing pin mechanism makes reliable contact with the solder strips and the battery pieces when pressed downwards. In addition, the welding head is located at the best welding distance through adjustment of the lifting mechanism, and then the battery string is conveyed to the next station through the conveying mechanism after being welded with the infrared welding head. Meanwhile, the heating platform further plays the function of slow cooling through temperature control over different parts, and the breaking rate in the welding process is effectively lowered.

Description

technical field [0001] The invention relates to a solar battery string welding machine, in particular to a battery string infrared welding device. Background technique [0002] The welding device is the core part of the stringer, which often determines the welding quality of the battery string and the efficiency of the equipment. Currently commonly used welding methods are infrared light source welding and electromagnetic welding. Electromagnetic welding breaks down the battery sheet due to excessive edge temperature, resulting in the risk of battery short circuit. In particular, there are many impurities in domestic cells, which further increases the probability of breakdown. Therefore, the infrared light source welding method is often adopted by domestic stringer manufacturers. At present, the lamp tubes used as the infrared light source welding head are arranged in parallel with the main grid line, which can meet the general welding effect, but there is a compatibility...

Problems solved by technology

At present, the lamp tubes used as infrared light source welding heads are arranged in parallel with the main grid line, which can meet the general welding effect, but there are compatibility issues with different grid line batteries

Moreover, the surface pressure mechanism used to press the battery string can easily affect the welding effect, and the battery sheet will be damaged when the pressure is uneven, and it will also cause serious wear and tear on the transmission mechanism of the steel belt for a long time.
