Solar cell string automatic superposition welding machine

Abstract

A solar cell string automatic superposition welding machine is disclosed and comprises a machine rack, a front end confluence belt supply device, a tail end confluence belt supply device, a front end confluence belt welding device, a tail end confluence belt welding device, an insulating film supply device and a cell string group bearing plate, wherein the front end confluence belt supply device is used for cutting born confluence belts and folding each of cut confluence welding belts into an L shape, the insulating film supply device is used for cutting born insulating film belts and obtaining insulating film strips, the bent confluence welding belts are placed on front ends of interconnecting belts of cell strings on the cell string group bearing plate via the front end confluence belt welding device, and therefore welding operation can be conducted; the insulating film strips are placed on the bent confluence welding belts via the front end confluence belt welding device, and therefore the bent confluence welding belts can be insulated from each other; the tail end confluence belt supply device and the tail end confluence belt welding device are used for fixing interconnecting belts of rear ends of the cell strings onto the confluence welding belts in a cooperating manner, and therefore the cell strings can be connected in series. No manual welding operation is required, and the confluence belts can be welded onto the interconnecting belts in a high quality manner.

Description

Technical field: [0001] The invention relates to the technical field of solar cell sheet welding, in particular to a solar cell string automatic stitch welding machine. Background technique: [0002] In the manufacturing process of crystalline silicon solar cell modules, the solar cells are connected in series with interconnection ribbons (ie, welding ribbons), which is called the stringing process. Arranged on the glass plate, and make the front of the solar cells face up (that is, the surface irradiated by sunlight). The auxiliary materials are stacked, that is, the series welding of the battery strings and the bus belts for the battery strings is completed, which is called the stitch welding process in the component factory. Moreover, in the component manufacturing industry, interconnection ribbons (ie, solder ribbons) and confluence ribbons are both tin ribbons, which are used in solar modules. The interconnection strip (that is, the welding strip) is used to connect a...

AI Technical Summary

Problems solved by technology

[0003] At present, in the stringing process of the module factory, there is already a solar cell stringer that replaces manual welding, but in the stacking process, due to the complicated work procedures, the traditional manual stacking welding method is still used at present. There are common problems such as uneven soldering, large differences in consistency and aesthetics, and the difficulty and cost of personnel management continue to increase, which reduces the profit of component factories.
