Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic component production, in particular to a photovoltaic component glue overflow cutting head. Background Art

[0002] Solar cell modules convert sunlight into electricity. During production, a photovoltaic film is added between the photovoltaic cells and the photovoltaic glass to protect the cells. The film typically uses a split film, EVA film, or EPE film to cushion and protect the cells, improving light transmittance. The film is liquefied and evenly applied between the two layers of glass. A laminator then presses the liquefied film evenly.

[0003] However, after the liquefied film is pressed tightly by the laminator, it may overflow. To ensure a neat frame for the photovoltaic module, the edges and corners of the module must be treated for overflow. Existing methods of dealing with overflow glue typically involve manual cutting with a knife. This manual cutting method is labor-intensive and inefficient. Utility Model Content
