Description

Technical Field

[0001] The utility model relates to the technical field of solar photovoltaic components, in particular to an EVA paving and leveling device for photovoltaic components. Background Art

[0002] Photovoltaic module EVA is a special material. The full name of EVA is ethylene-vinyl acetate copolymer. In the photovoltaic industry, EVA is usually used as a packaging material for photovoltaic modules. Photovoltaic modules are solar power generation devices that stack photovoltaic cells, glass, EVA film, backplane and other materials layer by layer. In photovoltaic modules, EVA is mainly used to encapsulate and fix solar cells.

[0003] Photovoltaic laminates are composed of back glass, POE\EVA, battery cells, POE\EVA, and front glass. EVA, which is close to the front glass, has uneven laying and bulges during the laying process. During layout and stack welding, the battery cells adsorbed by the suction cup come into contact with the bulged EVA during the downward pressure process, which may cause hidden cracks in the battery cells. During the circulation of components, the bulge of EVA may cause the battery string to scratch the structure, and the battery string is at risk of being scrapped. Uneven EVA laying can easily cause batch fragmentation, affecting production efficiency and increasing production costs. In order to reduce the battery cell breakage rate, the problem of uneven EVA laying before layout needs to be solved. Utility Model Content
