Insulation film preseparation device

Abstract

The invention relates to an insulation film preseparation device. The defects that insulation film sticking is manually carried out in the prior art, the efficiency is low, and sticking quality is poor are overcome. The insulation film preseparation device comprises a machine frame and a moving assembly arranged on the machine frame in a sliding mode. The upper surface of the moving assembly is a film base belt supporting surface. The moving assembly is provided with a circular arc stripping corner. A film base belt passes over the stripping corner from the supporting surface and turns. The moving assembly moves an insulation film on the film base belt relative to the machine frame to pass over the stripping corner, the insulation film warped up, only one small part of the insulation film is left to be stuck to the film base belt, and the other large-area part is separated from the film base belt. The insulation film is stripped through contraction of the moving assembly, the insulation film on the film base belt is reset again through stretching of the moving assembly, at the moment, the insulation film can be conveniently extracted, and therefore the sticking speed of the insulation film can be improved. By means of preseparation, when the insulation film is extracted, the insulation film is not damaged and can be conveniently and directly grabbed by a mechanical hand.

Description

technical field [0001] The invention relates to the photovoltaic field, in particular to an insulating film pre-separation device. Background technique [0002] During the preparation process of photovoltaic cells, due to the slurry, operation methods or the existence of dust, when the photovoltaic cells are soldered with ribbons, the positive and negative electrodes of adjacent cells are prone to conduction, resulting in a short circuit of the battery and affecting the quality of the product. Quality and Yield. [0003] In order to solve this problem, the traditional method is to polish the edge of the battery substrate after the detection and sorting of the battery substrate, and process the edge of the battery substrate to remove dust and other influencing factors to ensure that the edge of the battery substrate is on the edge of the welding ribbon. After that, it will not cause positive and negative conduction. However, this method has a high labor cost, and the thickn...

Problems solved by technology

[0006] The invention solves the defects of low efficiency and low pasting quality of manual insulating film paste in the prior art, and provides an insulating film pre-separation device, which can pre-separate the insulating film from the film base tape and improve the extraction speed of the insulating film. At the same time, it also improves the speed of sticking the insulating film. At the same time, through pre-separation, it avoids damage to the insulating film.
