[0001] The utility model relates to the field of photovoltaic glass, in particular to a photovoltaic glass appearance detection device. Background Art

[0002] Photovoltaic glass is widely used as protective glass for solar panels. During production, photovoltaic glass is transported from one process to the next on the glass conveyor line. The edges of the photovoltaic glass must be ground, and the quality requirements for grinding are strict. Usually, the size of defects such as bottom leakage, corner burst, edge burst, and burnt edge is required to be no larger than 0.5mm. At the same time, there are certain requirements for the chamfer size of the glass edge grinding.

[0003] Currently, common photovoltaic glass appearance flip inspection machines have a simple structure. They clamp the photovoltaic glass by manually turning screws to adjust and fix it, which requires a lot of time and effort, significantly reducing the inspection efficiency of the photovoltaic glass. Furthermore, existing photovoltaic glass inspection machines can only adjust the position of the inspection head, not the position of the photovoltaic glass itself. This limits the inspection range, making it difficult to fully inspect the photovoltaic glass and prone to missed inspections. To address this issue, we have developed a photovoltaic glass appearance inspection device. Utility Model Content
