[0023] like Figure 1 , Figure 2 , Figure 3As shown, the utility model provides a backboard removal device for a photovoltaic module, comprising a frame 1, a fixing frame 7 is fixedly installed on the top and side wall surfaces of the frame 1, a lubricating mechanism 8 is installed on one side outer wall of the fixing frame 7, and the lubricating mechanism 8 is connected to the fixing frame 7 through a hose, and comprises a cylindrical hollow block 11, the hollow block 11 is clamped in a clamping ring 12, and the clamping ring 12 is fixedly installed on the fixing frame 7, a lubricating sponge 15 is fixedly provided at the bottom end of the hollow block 11, and the lubricating sponge 15 is filled with lubricating oil, a plurality of oil outlet holes 14 are opened on the shell wall at the bottom end of the hollow block 11, and the oil outlet holes 14 correspond to the positions of the lubricating sponges 15, and a lubricating head 13 is connected to the bottom of the hollow block 11, and the lubricating head 13 is arranged at the oil outlet hole 14 At the bottom, a movable block 10 is suspended just above the lubricating sponge 15. The movable block 10 is slidably arranged in the hollow block 11, and its upper end extends to the outside of the hollow block 11. A pressing plate 9 is fixedly arranged on the top of the movable block 10, and a telescopic rod 18 is installed on the bottom surface. An extrusion plate 16 is vertically fixed on the bottom telescopic end of the telescopic rod 18, and a spring 19 is sleeved on the outside of the telescopic rod 18. The spring 19 is fixedly connected between the bottom surface of the movable block 10 and the extrusion plate 16. The diameter of the extrusion plate 16 is larger than the diameter of the lubricating sponge 15. Slide blocks 17 are symmetrically fixedly arranged on both sides of the outer surface of the movable block 10. Slide grooves 1701 are provided on the inner walls of both sides of the hollow block 11 at positions corresponding to the slide blocks 17, and the slide blocks 17 are slidably arranged in the slide grooves 1701;

[0024] When using the device, place the photovoltaic module on the placement plate, use the cleaning brush 22 to clean the back plate, and then remove the lubricating mechanism 8 stuck in the clamping ring 12. The setting of the clamping ring 12 and the hose can prevent the lubricating mechanism 8 from falling and facilitate the removal of the lubricating mechanism 8. After removing the lubricating mechanism 8, align the screws on the back plate and press the pressing plate 9. The pressing plate 9 moves downward to drive the movable block 10, and also drives the slider 17 to slide in the slide groove 1701. The movable block 10 drives the telescopic rod 18 to move downward, and the telescopic rod 18 drives the squeezing plate 16 to move downward. When the squeezing plate 16 contacts the lubricating sponge 15, it continues to squeeze the pressing plate 9 downward. The pressing plate 9 begins to compress the telescopic rod 18 and the spring 19. The spring 19 is deformed by force, thereby having elastic potential energy to restore to its original shape. When the telescopic rod 18 is compressed When it is at its shortest, continue to squeeze the pressing plate 9 downward so that the pressing plate 9 can drive the squeezing plate 16 to compress the lubricating sponge 15. After the lubricating sponge 15 is compressed, the lubricating oil filled therein flows out through the oil outlet 14, and finally flows to the screw through the lubricating head 13. Then, release the pressing plate 9. Under the action of the spring 19, it rebounds and drives the movable block 10 to move upward, so that the squeezing plate 16 leaves the lubricating sponge 15. The lubricating sponge 15 gradually returns to its original state, and then the next screw can be lubricated. When the device is in use, through the lubrication mechanism 8, if it is found that the screws used to fix the back plate of the photovoltaic module are rusted during the removal of the back plate, the lubrication mechanism 8 can be removed, and the pressing plate 9 can be pressed downward to squeeze the lubricating sponge 15, so that the lubricating oil flows out to lubricate the screws, which is convenient for disassembly.

[0026] When using the device, the photovoltaic component is placed on the placement plate. According to the thickness of the photovoltaic component, the electric push rod 20 is started, so that the electric push rod 20 drives the mounting frame 21 to move downward, and the mounting frame 21 drives the cleaning brush 22 to move downward until the position of the cleaning brush 22 can contact the photovoltaic component. At the same time, the servo motor 23 and the forward and reverse motor 2 are started. The forward and reverse motor 2 drives the screw rod 3 to rotate. When the screw rod 3 rotates, the ball nut 4 moves on the screw rod 3. According to the different rotation directions of the forward and reverse motor 2, the ball nut 4 makes a reciprocating motion. When the ball nut 4 moves, it drives the slide bar 5 to move in the moving groove 501, and the slide bar 5 drives the placement plate to move. When the placement plate drives the photovoltaic component to move, it drives the ball to roll. The ball can play a guiding role and provide certain support to the placement plate.
