Description

Technical Field

[0001] This invention relates to the field of photovoltaic module manufacturing technology, and more specifically, to an automatic edge-sealing machine for photovoltaic module manufacturing. Background Technology

[0002] Photovoltaic modules are core power generation devices that convert solar energy into electrical energy using the photovoltaic effect. They are encapsulated by solar cells, EVA film, and tempered glass.

The components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0020] According to an embodiment of the present invention, an automatic edge-sealing machine for photovoltaic module production is provided.

[0021] Example 1 like Figure 1-8 As shown, an automatic edge-sealing machine for photovoltaic module production according to an embodiment of the present invention includes a machine base 1. L-shaped fixing frames 2 are provided on both sides of the top of the machine base 1. Electric push rods 3 are provided on the opposite sides of the two sets of L-shaped fixing frames 2. The movable end of the electric push rod 3 passes through the L-shaped fixing frame 2 and is connected to the edge-sealing device 31. Two sets of hollow placement plates 4 are provided at the top of the machine base 1. The two sets of hollow placement plates 4 are connected to the machine base 1 via a moving adjustment mechanism. The moving adjustment mechanism includes a lead screw 5 provided in the machine base 1. A movable seat 6 is sleeved on the outer wall of the lead screw 5. Each movable seat 6 is connected to the two sets of hollow placement plates 4 via a fixed support seat 7. A guide slide rod 8 is symmetrically arranged and passes through the movable seat 6. A limiting mechanism matching the movable seat 6 is provided in the machine base 1. Several evenly distributed adsorption holes 9 are opened at the top of the hollow placement plate 4. An air extraction mechanism matching the hollow placement plate 4 is provided on the movable seat 6. The lead screw 5 is connected to the machine base 1 via a bearing. One end of the lead screw 5 extends outside the machine base 1 and is connected to the drive end of the servo motor 10. The movable seat 6 has a threaded hole that matches the lead screw 5 and a guide sliding hole that matches the guide slide rod 8.

[0022] In use, two sets of photovoltaic modules are placed on two sets of hollow placement plates 4 and fixed by suction mechanism. Then, the electric push rod 3 is started to drive the edge sealing device 31 to the sides of the two sets of photovoltaic modules for edge sealing. After completion, the servo motor 10 is started to drive the lead screw 5 to rotate. The lead screw 5 drives the moving seat 6 to rotate. The moving seat 6 drives the two sets of hollow placement plates 4 to move through the fixed support 7. This moves the processed photovoltaic modules to the top side of the machine 1. The other set of photovoltaic modules to be processed is moved to the edge sealing area of ​​the machine 1 for edge sealing. Then, the personnel can pick up and replace the processed photovoltaic modules. The two sets of hollow placement plates can be switched back and forth by setting the moving adjustment mechanism. When edge sealing one set of photovoltaic modules, the other set of photovoltaic modules to be edge sealed can be placed on the other set of hollow placement plates. When the edge sealing of one set of photovoltaic modules is completed, the next set of photovoltaic modules can be moved to the edge sealing area in time for edge sealing, saving the time of picking up and placing photovoltaic modules and improving the edge sealing efficiency.

[0023] Example 2 like Figure 1-8 As shown, the limiting mechanism includes symmetrically arranged U-shaped fixing frames 11 on both sides of the machine base 1. A slider 12 is provided in the U-shaped fixing frame 11. A guide slide rod 13 is symmetrically arranged and passes through the slider 12 in the U-shaped fixing frame 11. A spring 14 is sleeved on the outer wall of the guide slide rod 13 on the side of the slider 12 away from the machine base 1. An electromagnet 15 is provided on the inner wall of the U-shaped fixing frame 11. An iron block 16 matching the electromagnet 15 is provided on the side of the slider 12 away from the machine base 1. A limiting rod 17 is provided on the side of the slider 12 away from the iron block 16. One end of the limiting rod 17 extends into the machine base 1. A limiting groove 18 matching the limiting rod 17 is provided on both sides of the movable seat 6. The bottom of the movable seat 6 is provided with a travel block 19, and the bottom of the machine base 1 is provided with a travel groove 20 that matches the travel block 19. Both sides of the inner wall of the travel groove 20 are provided with touch sensors 21, and the touch sensors 21 and the electromagnet 15 are electrically connected to an external controller. The slider 12 is provided with a guide hole 2 that matches the guide slide rod 2 13. The slider 12 is connected to the U-shaped fixing frame 11 through the spring 14, and the end of the guide slide rod 2 13 near the machine base 1 is provided with an anti-detachment block.

[0024] When the movable seat 6 moves, it drives the travel block 19 to move until one side of the travel block 19 presses against the sensor 21. At this time, the electromagnet 15 is de-energized, the iron block 16 separates from the electromagnet 15, the spring 14 returns to its original position, and drives the slider 12 to move. The slider 12 drives the limit rod 17 to move until the limit rod 17 is inserted into the limit groove 18 on the movable seat 6 and is fixed in place. By setting the limit mechanism, the movable seat can be limited to prevent the hollow placement plate from moving during the edge sealing process, making it more stable. Example 3 like Figure 1-8 As shown, the suction mechanism includes a suction box 22 located at the top of the movable seat 6 and between the two sets of fixed support seats 7. The suction box 22 has symmetrically arranged suction chambers 23, each with a matching piston 24. Both sides of the suction box 22 have ventilation pipes 25 connected to the two sets of suction chambers 23, respectively. The ends of the two ventilation pipes 25 away from the suction box 22 are connected to the two sets of hollow placement plates 4. The top of the suction box 22 has symmetrically arranged drive boxes 26, each connected to one of the two sets of suction chambers 23. Each drive box 26 contains a lead screw 27, and a movable sleeve 28 is fitted onto the outer wall of the lead screw 27. The bottom end of the movable sleeve 28 extends into the suction chamber 23 and connects to the piston 24. The second lead screw 27 is connected to the drive box 26 via the second bearing. The top end of the second lead screw 27 extends outside the drive box 26 and is connected to the drive end of the second servo motor 32. The inner wall of the movable sleeve 28 has a threaded groove that matches the second lead screw 27. The outer wall of the movable sleeve 28 has symmetrically arranged guide blocks 29. The inner wall of the drive box 26 has a guide groove 30 that matches the guide blocks 29.

[0025] When fixing the photovoltaic module, the photovoltaic module is placed on the hollow placement plate 4. Then, the servo motor 22 is started to drive the lead screw 27 to rotate. The lead screw 27 drives the moving sleeve 28 to move upward. The moving sleeve 28 drives the piston 24 to move upward. When the piston 24 moves upward, it evacuates the air inside the hollow placement plate 4. At this time, the adsorption holes 9 on the hollow placement plate 4 adsorb and fix the photovoltaic module. By setting the air extraction mechanism, the photovoltaic module can be adsorbed and fixed without clamping, avoiding scratches on the surface of the photovoltaic module, making it safer and more reliable.

[0026] In summary, by utilizing the above-mentioned technical solution of the present invention, the two sets of hollow placement plates can be switched back and forth by setting a movable adjustment mechanism. This allows the other set of photovoltaic modules to be edge-sealed to be placed on the other set of hollow placement plates while one set of photovoltaic modules is being edge-sealed. After the edge-sealing of one set of photovoltaic modules is completed, the next set of photovoltaic modules can be moved to the edge-sealing position in a timely manner, saving the time of picking up and placing photovoltaic modules and improving the edge-sealing efficiency. The setting of a limiting mechanism can limit the movement of the movable seat to prevent the hollow placement plates from moving during the edge-sealing process, making it more stable. The setting of an air extraction mechanism can adsorb and fix the photovoltaic modules without clamping, avoiding scratches on the surface of the photovoltaic modules and making it safer and more reliable.
