The invention discloses a solar panel breakage detection device, which comprises a dark box used for placing a solar panel, wherein the solar panel is electrically connected to a DC power supply, the internal part of the dark box is provided with an optical reflector below the solar panel, the external part is correspondingly provided with a CCD near-infrared camera used for receiving luminescent images reflected by the optical reflector, and the CCD near-infrared camera is connected to a computer provided with a display device. The solar board breakage detection device removes a scanning mechanism, and is simple in structure and convenient for online detection of a solar panel production line; an optical path is lengthened by using a mirror reflection principle, and image deformation is reduced; and the CCD near-infrared camera is used, and the definition of solar panel breakage imaging is effectively improved.
Description
technical field [0001] The invention relates to the technical field of detection equipment, in particular to a solar battery panel damage detection device. Background technique [0002] Solar panel damage detection is a key process in the production process of solar panels or components. Since silicon solar panels are usually sliced from polycrystalline or single crystal rods, damage may occur in every link of the production process. Defects such as hidden cracks, fragments, chipping, virtual welding, and broken grids occur. If the thickness of the slice is reduced, the amount of silicon material used can be reduced, the cost can be reduced, and the energy consumption can be reduced, but the rate of damage will increase accordingly. [0003] The current solar panel damage detection method is mainly an infrared detection method, which uses a laser light source of a certain wavelength to scan the solar panel point by point, and the corresponding photosensitive element detec...
