[0014] A method for preparing a double-sided glass photovoltaic module comprises the following steps: S1: Fixed border First, place the frame for fixing the photovoltaic module that needs to be polished on the inner side of the load-bearing plate, and make the frame in the middle position of the inner side of the clamping plate. According to the size of the frame, the first servo motor drives the movable seat connected to the outer thread of the bidirectional threaded rod to move, so that the movable seat drives the load-bearing plate and the clamping plate to move, adjust the distance between the clamping plate and the load-bearing plate, and move the clamping plate to the left and right sides of the frame. The frame can be fixed under the action of the clamping plate, and the upper and lower sides of the frame are on the periphery of the clamping plate, which does not affect the subsequent polishing work. When the fixation is completed, the support plate is driven to rise and fall by the third cylinder at the same time, so that the top of the support plate and the bottom of the frame are in contact with each other, which can further ensure the stability of the frame during polishing. S2: Polishing of the border The third servo motor drives the moving block connected to the outer thread of the one-way threaded rod to move, so that the moving block drives the L-shaped frame to move, and the left and right position of the grinding disc is adjusted according to the position where the frame needs to be polished. At the same time, the first cylinder drives the bearing platform to move back and forth, and the front and back position of the grinding disc is further adjusted. When the adjustment is completed, the second cylinder can be used to drive the connecting plate to rise and fall, so that the connecting plate drives the grinding plate to rise and fall, so that the grinding disc can be brought into contact with the position where the frame needs to be polished. At the same time, the fourth servo motor drives the grinding disc fixedly connected to the bottom of the second rotating rod to rotate, and the frame can be polished under the action of the grinding disc. During the grinding process, the grinding disc can be driven by the first cylinder and the one-way threaded rod to move back and forth, left and right, thereby improving the comprehensiveness of the grinding. S3: Rotary grinding When one side of the frame is polished, the polishing disc is first located at the far right side under the action of the one-way threaded rod, and the supporting plate is moved away from the bottom of the frame. At the same time, the worm gear meshed at the rear side of the worm is driven to rotate by the second servo motor, so that the worm gear drives the clamping plate fixedly connected to the left side of the first rotating rod to rotate, and the clamping plate drives the supporting block to slide in the circular groove, and the frame can be driven to rotate under the action of the clamping plate, so that the unpolished side of the frame is at the top, and the bottom of the frame is supported again under the action of the supporting plate, and the left and right, front and back, and up and down positions of the polishing disc are adjusted under the action of the one-way threaded rod, the first cylinder and the second cylinder, and the frame is further polished under the action of the polishing disc to improve the efficiency and quality of polishing. When polishing is completed, the frame can be removed; S4: Waste collection The waste chips generated during the grinding process will fall to the bottom of the base and enter the collection box through the collection groove inside the base for centralized storage. When the collected waste chips need to be processed, just take out the collection box.

[0015] Compared with the prior art, the present invention provides a double-sided glass photovoltaic module and a preparation method thereof, which has the following beneficial effects: 1.

[0016] 2. The double-sided glass photovoltaic module and the preparation method thereof can realize the grinding work of the fixed frame of the photovoltaic module after cutting under the action of the grinding disk through the provided grinding mechanism, and the left and right, front and back, and up and down positions of the grinding disk can be adjusted under the action of the one-way threaded rod, the first cylinder and the second cylinder, that is, the frame can be fully polished under the action of the grinding disk, thereby improving the efficiency and quality of grinding and avoiding the phenomenon of grinding dead angles.

[0017] 3. The double-sided glass photovoltaic module and the preparation method thereof can collect the waste chips generated during the grinding process under the action of the base and the collection box through the collection mechanism. The collection can avoid the accumulation of waste chips and the grinding work, and can also avoid the falling of waste chips and the impact on the working area.

9. A method for preparing a double-sided glass photovoltaic module, characterized in that: The following steps are involved: S1: Fixed border First, a frame for fixing a photovoltaic module to be polished is placed inside the load-bearing plate (24), and the frame is located in the middle of the inner side of the clamping plate (291). According to the size of the frame, the first servo motor (21) drives the movable seat (22) connected to the outer thread of the bidirectional threaded rod (23) to move, so that the movable seat (22) drives the load-bearing plate (24) and the clamping plate (291) to move, and the distance between the clamping plate (291) and the load-bearing plate (24) is adjusted, and the clamping plate (291) is moved to the left and right sides of the frame. The frame can be fixed under the action of the clamping plate (291), and the upper and lower sides of the frame are located outside the clamping plate (291), which does not affect the subsequent polishing work. When the fixing is completed, the support plate (45) is driven to rise and fall by the third cylinder (44), so that the top of the support plate (45) and the bottom of the frame are in contact with each other, so as to further ensure the stability of the frame during the polishing work. S2: Polishing of the border The third servo motor (31) drives the moving block (34) connected to the outer thread of the one-way threaded rod (33) to move, so that the moving block (34) drives the L-shaped frame (35) to move, and the left and right positions of the grinding disc (392) are adjusted according to the position of the frame to be polished. At the same time, the first cylinder (37) drives the bearing platform to move forward and backward, and further adjusts the front and rear positions of the grinding disc (392). When the adjustment is completed, the second cylinder (38) drives the connecting disc (39) to move up and down, so that the connecting disc (39) can be moved forward and backward. The receiving plate (39) drives the grinding plate (392) to move up and down, so that the grinding plate (392) can be brought into contact with the position of the frame that needs to be polished. At the same time, the fourth servo motor (391) drives the grinding plate (392) fixedly connected to the bottom of the second rotating rod (393) to rotate, so that the frame can be polished under the action of the grinding plate (392). During the polishing process, the first cylinder (37) and the one-way threaded rod (33) can drive the grinding plate (392) to move forward, backward, left and right, thereby improving the comprehensiveness of the polishing. S3: Rotary grinding When the grinding of one side of the frame is completed, the grinding disc (392) is firstly moved to the rightmost side under the action of the one-way threaded rod (33), and the support plate (45) is moved away from the bottom of the frame. At the same time, the worm wheel (28) meshed with the rear side of the worm (27) is driven to rotate by the second servo motor (25), so that the worm wheel (28) drives the clamping plate (291) fixedly connected to the left side of the first rotating rod (29) to rotate, and the clamping plate (291) drives the support block (292) to slide in the circular groove, so that the clamping plate (291) can be rotated. The frame is driven to rotate under the action of (291), so that the unpolished side of the frame is at the top, and the bottom of the frame is supported again under the action of the support plate (45), and the left-right, front-back and up-down positions of the grinding disc (392) are adjusted under the action of the one-way threaded rod (33), the first cylinder (37) and the second cylinder (38), and the frame is further polished under the action of the grinding disc (392), thereby improving the efficiency and quality of polishing, and the frame can be removed after polishing is completed; S4: Waste collection The waste chips generated during the grinding process will fall to the bottom of the base (42) and enter the collection box (43) through the collection groove inside the base (42) for centralized storage. When the collected waste chips need to be processed, the collection box (43) only needs to be taken out.
