[0002] Photovoltaic power generation is a power generation technology that uses the photovoltaic effect of semiconductor interfaces to directly convert solar energy into electrical energy. At present, photovoltaic power generation has received widespread attention from countries around the world and has developed into an emerging industry. Photovoltaic modules are one of the most important equipment in photovoltaic power stations. Common photovoltaic modules are usually composed of glass, adhesive layer, battery cell, adhesive layer and backplane in sequence. Glass and backplane wrap the battery cell to prevent the battery cell from being damaged by the outside world. Since the backplane is in contact with the external environment at all times and can reflect sunlight, the conversion efficiency of the photovoltaic module is improved. It has a high infrared emissivity and can reduce the temperature of the module. Therefore, the backplane is usually the first to be damaged in the photovoltaic module, and the damaged backplane will reduce the power generation efficiency of the photovoltaic module. In order to avoid unnecessary waste, the photovoltaic module with damaged backplane needs to be brought back to the workshop for replacement of the backplane. However, the common replacement efficiency is to tear off the backplane manually, which wastes a lot of manpower and material resources. At the same time, the replacement efficiency of the backplane is not high. Even if a mechanical removal method is used, human participation is still required.

[0041] As a specific embodiment of the photovoltaic module back plate removal device provided by the present invention, please refer to Figures 2 to 3 The preheating component 3 is provided with a first bracket 31, a grinding plate 32 and a first motor 33; the grinding plate 32 is rotatably arranged on the first bracket 31 and the rotation axis is perpendicular to the horizontal plane, and the grinding plate 32 can contact the back plate; the first motor 33 is fixed on the first bracket 31 and drives the grinding plate 32 to rotate by belt transmission, and the first motor 33 is electrically connected to the controller. A first bracket 31 is provided inside the preheating component 3, and a grinding plate 32 is rotatably provided on the first bracket 31 with the axis of rotation in a vertical plane. The side of the grinding plate 32 with abrasive grains contacts the back plate, and heat is generated by friction between the abrasive grains and the back plate.

The saw blade 42 is fixedly arranged on the rotating shaft, and a pulley with an outer diameter smaller than the outer diameter of the saw blade 42 is fixed on the rotating shaft. Then, the second motor 43 drives the pulley coaxial with the saw blade 42 to rotate in the form of belt transmission.
