Backboard recovery system of photovoltaic module

The utility model discloses a backboard recovery system of a photovoltaic module, which comprises a feeding mechanism, a grinding mechanism suspended above the feeding mechanism, a cleaning mechanism,a collecting mechanism, a feeding mechanism bearing and linearly conveying the photovoltaic module along a preset direction, the grinding mechanism grinding the backboard at the top of the photovoltaic module with the frame removed below into powder, and the collecting mechanism collecting the powder. The cleaning mechanism cleans the grinding part of the photovoltaic module in the process that the grinding mechanism grinds the back plate, and the collecting mechanism collects powder and cleaning liquid generated by grinding the back plate. According to the utility model, the grinding mechanism is adopted to grind the backboard of the photovoltaic module with the frame removed, the grinding part is cleaned in the grinding process, and the powder and the cleaning liquid generated by grinding the backboard are coll
