Problems solved by technology

[0005] After research, it was found that in the lamination process, during the vacuuming stage, the silica gel plate located between the upper and lower chambers would sag due to gravity, causing downward extrusion on the components located in the lower chamber of the laminator, resulting in hidden cracks produce

Abstract

The invention discloses a laminating method of a photovoltaic assembly. In the vacuumizing stage, the pressure of an upper chamber is lower than that of a lower chamber, so that pressure difference is generated between the upper chamber and the lower chamber; and the vacuum degree of the upper chamber of the laminating equipment is greater than that of the lower chamber, so that silica gel plates on the lower side of the upper chamber are always adsorbed by the upper chamber, assemblies in the lower chamber of the laminating machine cannot be pressed down, invisible crack are not generated on the photovoltaic assembly, and defective products are reduced in the production process of photovoltaic assemblies. The invention also discloses a laminating machine of the photovoltaic assembly by using the laminating method.

Description

technical field [0001] The invention relates to the field of photovoltaic technology, in particular to a method for laminating photovoltaic components. In addition, the invention also relates to a lamination machine for photovoltaic modules. Background technique [0002] During the entire production process of photovoltaic modules, there will be defective products with different problems, which have a great impact on the production cost of photovoltaic enterprises, so controlling the number of defective products and reducing production costs are the primary tasks of all photovoltaic processing enterprises. [0003] In the research on all kinds of defective products, it is found that the biggest difficulty in controlling defective products is the invisible cracks that are invisible to the human eye, accounting for about 40% to 50% of all defective products. Due to this inherent quality problem, the human eye is intuitive It is invisible on the surface and can only be found b...
