Description

Technical Field

[0001] This invention belongs to the field of photovoltaic module vacuum laminator technology, specifically relating to a photovoltaic module vacuum laminator with an air spring. Background Technology

[0002] The photovoltaic module vacuum laminator is the core equipment for solar panel encapsulation. It uses vacuum, heating and pressure to press glass, EVA film, solar cells and backsheet into one piece. The vacuum environment can eliminate air bubbles and impurities, avoiding the generation of air bubbles that affect the performance of the module. Heating and pressurization can achieve high-strength bonding between materials, thereby preventing the solar cells from shifting or breaking, thus ensuring the long-term stable operation of the module.

[0003] Chinese patent CN113889549A discloses a vacuum laminator for photovoltaic cell module production. By utilizing airbags and exhaust pipes, the gas extracted during the vacuum lamination process is recovered and reused, thereby making full use of the kinetic energy of the air pump.

[0004] To prevent dust from being laminated into the photovoltaic modules, the cleanliness of the environment around the vacuum laminator must be ensured. Currently, most photovoltaic module production requires workers to manually push the photovoltaic module substrate into the vacuum laminator. Since workers need to push the substrate in manually, they inevitably come into contact with the substrate. If workers do not pay attention to cleaning their hands, dust may fall onto the substrate, thus affecting the production of photovoltaic modules. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a photovoltaic module vacuum laminator with an air spring.

[0006] The technical solution adopted to solve the above technical problems is: A photovoltaic module vacuum laminator with an air spring includes a vacuum laminator body and a pusher platform. The vacuum laminator body has a closed door installed on its side wall, and the pusher platform has a push groove on its side wall. Sliding grooves are respectively opened on both sides of the push groove. The height of the sliding grooves is the same as the height of the closed door. A fixed frame is slidably connected in the sliding grooves. The fixed frame is driven by the pusher platform and holds a substrate in the fixed frame. The fixed frame includes a side rod and a semi-enclosed frame. The side rod and the side wall of the semi-enclosed frame are movably connected. The base plate is located in the clamping of the side rod and the semi-enclosed frame. A cavity is opened in the semi-enclosed frame. A sealing tube is installed in the cavity. Pistons are respectively provided on the inner walls of both ends of the sealing tube. A telescopic rod is fixedly provided on the side wall of the piston. A fixed block is provided at the other end of the telescopic rod. The push groove has a motion groove on the side wall facing the vacuum laminator body. A dual-axis motor is fixedly installed on the side wall of the motion groove. The two output ends of the dual-axis motor are respectively fixedly connected to a rotating component. A cleaning plate is installed on the top of the rotating component. A cleaning cloth is installed on the top of the cleaning plate. Two locking rods are fixedly installed on the side wall of the cleaning cloth. The positions of the two locking rods correspond to the positions of the two fixing blocks.

[0007] By using the above technical solution, a rotating component and a cleaning plate are set on the push platform for pushing and pulling out the substrate, so that the pushing out and sending out of the substrate can be completed by machine, making the processing of photovoltaic modules by the vacuum laminator more automated, thereby improving the production efficiency of photovoltaic modules.

[0008] Furthermore, two short rods are fixedly installed on the side wall facing the semi-enclosed frame. The side wall of the semi-enclosed frame has a limiting cavity, which is connected to the outside through a limiting hole. The short rods enter the limiting cavity through the limiting hole. A telescopic spring is fixedly installed at the other end of the short rods, and the other end of the telescopic spring is fixedly connected to the side wall of the limiting cavity.

[0009] Through the above technical solution, the side rod and the semi-enclosed frame are combined to clamp the substrate inside the entire fixed frame. Moreover, due to the setting of the telescopic spring, the side rod tends to move towards the semi-enclosed frame, thus firmly clamping the substrate.

[0010] Furthermore, the sealing tube is U-shaped, with both ends pointing away from the vacuum laminator body, and the sealing tube contains gas.

[0011] With the above technical solution, when the vacuum laminator body is pressing the substrate, it will first evacuate the inside to a vacuum state. Since the sealed tube contains gas, the external vacuum environment will cause the gas inside the sealed tube to expand, thereby pushing the two pistons, the telescopic rod and the fixed block outward.

[0012] Furthermore, a baffle is fixedly installed at the end of the short rod away from the side rod, and the telescopic spring is fixedly installed between the baffle and the side wall of the limiting cavity. The width of the baffle is greater than the width of the limiting hole.

[0013] Through the above technical solution, the baffle can prevent the short rod from completely detaching from the limiting cavity, thereby ensuring the limiting effect of the side rod and the semi-enclosed frame on the substrate. The force applied to the baffle by the telescopic spring will cause the side rod to have a tendency to move towards the semi-enclosed frame.

[0014] Furthermore, two through holes are provided on the side wall of the cavity away from the vacuum laminator body, and two fixing blocks extend out from the two through holes respectively. Fixing holes are provided on the side wall of the fixing blocks.

[0015] Through the above technical solution, the setting of the fixing hole allows the fixing block protruding from the perforation to be hooked by the matching component. When the substrate has not yet been pressed by the vacuum laminator body, the fixing block will be inside the perforation, and the matching component will not hook it out.

[0016] Furthermore, the telescopic rod includes an inner tube and an outer tube. The inner tube is fixedly connected to the piston sidewall, and the outer tube is movably sleeved outside the inner tube. An elastic sheet is fixedly provided on the sidewall of the outer tube, and two springs are fixedly provided on the sidewall of the cavity. The springs are provided with arc-shaped ends, and the sidewalls of the arc-shaped ends of the two springs abut against the sidewalls of the two elastic sheets respectively.

[0017] With the above technical solution, when the piston moves outward, the inner tube and the outer tube will move outward together, which will cause the elastic sheet to squeeze through the arc-shaped end of the spring. After the vacuum laminator body finishes pressing, the original air pressure inside the machine will slowly return, and then the piston will gradually return to the initial position. Due to the restriction of the spring, the outer tube will remain in the state of extending out of the perforation.

[0018] Furthermore, the rotating assembly includes an extension rod, a driving gear, a driven gear, a swing rod, a support rod, a connecting rod, and a sliding block. The extension rod is fixedly mounted on one of the output ends of the dual-axis motor, and the other end of the extension rod is fixedly connected to the center position of the driving gear. The swing rod is eccentrically mounted on the side wall of the driving gear, and the other end of the swing rod is rotatably connected to the side wall of the cleaning plate. The driven gear is rotatably connected to the side wall of the motion groove and meshes with the driving gear. The connecting rod is fixedly mounted on the center position of the driven gear, and the other end of the connecting rod is rotatably connected to the side wall of the sliding block. One end of the support rod is rotatably connected to the side wall of the motion groove, and the other end of the support rod is rotatably connected to the side wall of the cleaning plate. A reinforcing rod is provided in the support rod, and a sliding groove is formed in the reinforcing rod. The sliding block is slidably connected to the inner wall of the sliding groove.

[0019] With the above technical solution, when the dual-axis motor is running, it will drive the extension rod to rotate, which in turn will cause the drive gear at the other end of the extension rod to rotate. Due to the meshing of the drive gear and the driven gear, the driven gear will drive the connecting rod to rotate together. The rotation of the connecting rod will drive the sliding block to slide in the sliding groove, which will cause the cleaning plate to swing and pull out the fixing block on the side wall of the pressed fixing frame.

[0020] Furthermore, the cleaning plate is divided into two parts: a horizontal part and an inclined part. The top of the horizontal part is at the same height as the bottom of the substrate. An extension block is fixedly installed at the bottom of the horizontal part. The clamping rod is fixedly installed on the side wall of the extension block. The support rod is rotatably connected at the connection position between the horizontal part and the inclined part. The swing rod is rotatably connected to the side wall of the inclined part.

[0021] Through the above technical solution, the cleaning cloths at the top of both the horizontal and inclined portions can clean the bottom of the substrate. The inclined portion is designed so that the cleaning cloth on it will not directly contact the bottom of the substrate, and only the cleaning cloth on the horizontal portion can clean the bottom of the substrate.

[0022] Furthermore, a collecting roller is rotatably connected inside the horizontal part, a rotating cavity is opened inside the inclined part, a cleaning roller is rotatably connected to the side wall of the rotating cavity, and a cleaning cloth is wound between the collecting roller and the cleaning roller.

[0023] With the above technical solution, since the cleaning cloth above the inclined part does not directly contact the bottom of the substrate, when the cleaning cloth cleans the bottom of the substrate, the cleaning cloth will be rolled from the cleaning roller to the collection roller, which can ensure the cleanliness of the cleaning cloth and thus ensure the pressing quality of the photovoltaic module substrate.

[0024] Furthermore, a locking block is fastened to the side wall of the inclined portion, the locking block is located on one side of the swing rod, the rotating cavity is open, the locking block is engaged with the side wall of the open end of the rotating cavity, and both the cleaning roller and the collecting roller are separable.

[0025] With the above technical solution, before the cleaning cloth on the cleaning roller is used up, the staff can remove the used cleaning roller and replace it by removing the clip, thereby ensuring its long-term stable operation.

[0026] The beneficial effects of the present invention are as follows: (1) The present invention sets a rotating component and a cleaning plate on the push platform for pushing and pulling out the substrate. When the substrate and the fixed frame are pressed by the vacuum laminator, the fixing block on the side wall of the fixed frame will extend, which makes it convenient for the clamping rod on the side wall of the cleaning cloth to hook and pull it out. Before pressing, since the fixing block has not extended, the moving clamping rod will push the fixed frame and the substrate into the vacuum laminator together, thereby making the processing of photovoltaic modules by the vacuum laminator more automated and improving the production efficiency of photovoltaic modules. (2) The present invention pushes out the fixing block by setting a sealing tube on the side wall of the semi-enclosed frame. When the vacuum laminator body is pressing the substrate, it will first draw the inside into a vacuum state. Since the sealing tube contains gas, the external vacuum environment will cause the gas inside the sealing tube to expand, thereby pushing the two pistons, the telescopic rod and the fixing block outward, so that the clamping rod on the side wall of the cleaning plate can hook it out. (3) The present invention provides springs and elastic plates on the outside of the inner tube and the outer tube. When the piston moves outward, the inner tube and the outer tube will move outward together, so that the elastic plate is squeezed through the arc end of the spring. After the vacuum laminator body is pressed, the machine will slowly restore the original air pressure, and then the piston will gradually return to the initial position. Due to the restriction of the spring, the outer tube will remain in the state of extending out of the perforation. Attached Figure Description

[0029] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0030] like Figure 1 As shown, this embodiment provides a photovoltaic module vacuum laminator with an air spring, including a vacuum laminator body 1 and a pusher platform 2. A closed door 3 is installed on the side wall of the vacuum laminator body 1, and a pusher groove 4 is opened on the side wall of the pusher platform 2. Sliding grooves 5 are opened on both sides of the pusher groove 4. The height of the sliding groove 5 is the same as the height of the closed door 3. A fixed frame is slidably connected in the sliding groove 5, and the opening of the sliding groove 5 facing the closed door 3 is larger, making it easier to reconnect the hooked fixed frame. The fixed frame is driven by the pusher platform 2. The specific driving method is not an innovation of this application, so it will not be described here. There are many driving methods, such as gear rack, etc. The fixed frame holds a substrate 6, which refers to the photovoltaic module that has been laminated and stacked.

[0031] Reference Figures 2-4 The fixed frame includes a side rod 7 and a semi-enclosed frame 8. The side rod 7 and the semi-enclosed frame 8 are movably connected to each other. The substrate 6 is clamped between the side rod 7 and the semi-enclosed frame 8. Two short rods 17 are fixedly installed on the side wall of the side rod 7 facing the semi-enclosed frame 8. A limiting cavity is opened on the side wall of the semi-enclosed frame 8. The limiting cavity is connected to the outside through a limiting hole 18. The short rods 17 enter the limiting cavity through the limiting hole 18. A telescopic spring 19 is fixedly installed at the other end of the short rod 17. The other end of the telescopic spring 19 is fixedly connected to the side wall of the limiting cavity. The combined arrangement of the side rod 7 and the semi-enclosed frame 8 can clamp the substrate 6 inside the entire fixed frame. Moreover, due to the setting of the telescopic spring 19, the side rod 7 has a tendency to move towards the semi-enclosed frame 8, so the substrate 6 can be firmly clamped.

[0032] A baffle 20 is fixedly installed at the end of the short rod 17 away from the side rod 7. A telescopic spring 19 is fixedly installed between the baffle 20 and the side wall of the limiting cavity. The width of the baffle 20 is greater than the width of the limiting hole 18. The baffle 20 can prevent the short rod 17 from completely detaching from the limiting cavity, thereby ensuring the limiting effect of the side rod 7 and the semi-enclosed frame 8 on the substrate 6. The force applied by the telescopic spring 19 to the baffle 20 will cause the side rod 7 to have a tendency to move towards the semi-enclosed frame 8.

[0033] Combination Figure 3 , Figure 5 and Figure 6It is known that a cavity is formed in the semi-enclosed frame 8, and a sealing tube 9 is installed in the cavity. Pistons 10 are respectively installed on the inner walls of both ends of the sealing tube 9. The sealing tube 9 is U-shaped, and both ends of the sealing tube 9 point away from the side away from the vacuum laminator body 1. The sealing tube 9 stores gas. When the vacuum laminator body 1 presses the substrate 6, it first evacuates the interior to a vacuum state. Because the sealing tube 9 stores gas, the external vacuum environment will cause the gas inside the sealing tube 9 to expand, thereby pushing the two pistons 10, the telescopic rod and the fixing block 11 outward. A telescopic rod is fixedly installed on the side wall of the piston 10, and a fixing block 11 is installed at the other end of the telescopic rod. Two through holes 21 are opened on the side wall of the cavity away from the vacuum laminator body 1. The two fixing blocks 11 extend out of the two through holes 21 respectively. The side wall of the fixing block 11 is provided with a fixing hole 22. The fixing hole 22 is provided so that the fixing block 11 extending out of the through hole 21 can be hooked by the matching component. When the substrate 6 has not been pressed by the vacuum laminator body 1, the fixing block 11 will be inside the through hole 21, and the matching component will not hook it out.

[0034] The telescopic rod includes an inner tube 23 and an outer tube 24. The inner tube 23 is fixedly connected to the side wall of the piston 10. The outer tube 24 is movably sleeved outside the inner tube 23. An elastic plate 25 is fixedly installed on the side wall of the outer tube 24. Two spring plates 26 are fixedly installed on the side wall of the cavity. The spring plates 26 are provided with arc-shaped ends 27. The side walls of the arc-shaped ends 27 of the two spring plates 26 abut against the side walls of the two elastic plates 25 respectively. When the piston 10 moves outward, the inner tube 23 and the outer tube 24 will move outward together, thereby causing the elastic plate 25 to squeeze through the arc-shaped ends 27 of the spring plates 26. After the vacuum laminator body 1 finishes pressing, the internal air pressure of the machine will slowly return to the original position, and then the piston 10 will gradually return to the initial position. Due to the restriction of the spring plates 26, the outer tube 24 will remain in the state of extending out of the perforation 21.

[0035] Combination Figure 1 , Figure 7 and Figure 8It is known that a motion groove 12 is provided on the side wall of the vacuum laminator body 1 facing the push groove 4. A dual-axis motor 13 is fixedly installed on the side wall of the motion groove 12. Rotating components are fixedly connected to the two output ends of the dual-axis motor 13. The rotating components include an extension rod 28, a drive gear 29, a driven gear 30, a swing rod 31, a support rod 32, a connecting rod 33, and a sliding block 34. The extension rod 28 is fixedly installed on one of the output ends of the dual-axis motor 13. The other end of the extension rod 28 is fixedly connected to the center position of the drive gear 29. The swing rod 31 is eccentrically installed on the side wall of the drive gear 29. The other end of the swing rod 31 is rotatably connected to the side wall of the cleaning plate 14. The driven gear 30 is rotatably connected to the side wall of the motion groove 12 and meshes with the drive gear 29. The connecting rod 33 is fixedly installed on the driven gear 30. At the center, the other end of the connecting rod 33 is rotatably connected to the side wall of the sliding block 34, one end of the support rod 32 is rotatably connected to the side wall of the motion groove 12, and the other end of the support rod 32 is rotatably connected to the side wall of the cleaning plate 14. A reinforcing rod 35 is provided in the support rod 32, and a sliding groove 36 is provided in the reinforcing rod 35. The sliding block 34 is slidably connected to the inner wall of the sliding groove 36. When the dual-axis motor 13 is running, it will drive the extension rod 28 to rotate, which will cause the drive gear 29 at the other end of the extension rod 28 to rotate. Due to the meshing of the drive gear 29 and the driven gear 30, the driven gear 30 will drive the connecting rod 33 to rotate together. The rotation of the connecting rod 33 will drive the sliding block 34 to slide in the sliding groove 36, which will cause the cleaning plate 14 to swing and pull out the fixing block 11 on the side wall of the pressed fixing frame.

[0036] from Figures 8-10 As can be seen from the contents, a cleaning plate 14 is provided on the top of the rotating assembly, and a cleaning cloth 15 is provided on the top of the cleaning plate 14. The cleaning plate 14 is divided into two parts: a horizontal part 37 and an inclined part 38. The top of the horizontal part 37 is at the same height as the bottom of the substrate 6. The cleaning cloth 15 on the top of both the horizontal part 37 and the inclined part 38 can clean the bottom of the substrate 6. The setting of the inclined part 38 ensures that the cleaning cloth 15 on it will not directly contact the bottom of the substrate 6. Only the cleaning cloth 15 on the horizontal part 37 can clean the bottom of the substrate 6. An extension block 39 is fixedly provided at the bottom of the horizontal part 37. Two locking rods 16 are fixedly provided on the side wall of the cleaning cloth 15. The positions of the two locking rods 16 correspond to the positions of the two fixing blocks 11. The locking rods 16 are fixedly provided on the side wall of the extension block 39. The support rod 32 is rotatably connected at the connection position between the horizontal part 37 and the inclined part 38. The swing rod 31 is rotatably connected to the side wall of the inclined part 38.

[0037] A collecting roller 40 is rotatably connected inside the horizontal part 37, and a rotating cavity is opened inside the inclined part 38. A cleaning roller 41 is rotatably connected to the side wall of the rotating cavity. A cleaning cloth 15 is wrapped between the collecting roller 40 and the cleaning roller 41. Since the cleaning cloth 15 above the inclined part 38 does not directly contact the bottom of the substrate 6, when the cleaning cloth 15 cleans the bottom of the substrate 6, the cleaning cloth 15 will be rolled from the cleaning roller 41 onto the collecting roller 40, which can ensure the cleanliness of the cleaning cloth 15 and thus ensure the pressing quality of the photovoltaic module substrate 6. A locking block 42 is fastened to the side wall of the inclined part 38. The locking block 42 is located on one side of the swing rod 31. The rotating cavity is open. The locking block 42 is locked onto the side wall of the open end of the rotating cavity. Both the cleaning roller 41 and the collecting roller 40 are separable. Before the cleaning cloth 15 on the cleaning roller 41 is used up, the operator can remove the used cleaning roller 41 by removing the locking block 42 to replace it, thereby ensuring its long-term stable operation.

[0038] The working principle of this embodiment is as follows: First, pull open the side rod 7 and the semi-enclosed frame 8 so that the telescopic spring 19 is stretched, and the substrate 6 is inserted into the side rod 7 and the semi-enclosed frame 8. Release the side rod 7, and under the action of the telescopic spring 19, the side rod 7 will hold the position of the substrate 6. Then, the staff pushes it into the slide 5. Driven by the pusher 2, the substrate 6 will be pushed into the vacuum laminator body 1 with the closed door 3 open. At this time, the fixing block 11 is inside the perforation 21, and the cleaning cloth 15 above the horizontal part 37 will clean the bottom of the substrate 6. Since there is still a distance between the pusher platform 2 and the substrate 6 being completely pushed into the vacuum laminator body 1, the extension rod 28 will be rotated by the dual-axis motor 13 during this final distance. This will cause the drive gear 29 to rotate the driven gear 30. The swing rod 31 on the side wall of the drive gear 29 will cause the cleaning plate 14 to swing. The rotation of the driven gear 30 will then cause the connecting rod 33 to rotate. The sliding block 34 at the other end of the connecting rod 33 will slide in the sliding groove 36, causing the support rod 32 to rotate. Finally, the cleaning plate 14 will push the semi-enclosed frame 8 into the vacuum laminator body 1 until it reaches the appropriate position. When the vacuum laminator body 1 is working, it needs to be evacuated first. Therefore, the gas inside the sealing tube 9 will expand, which will push the two pistons 10 outward. The inner tube 23 and the outer tube 24 will be pushed out by the pistons 10. The elastic sheet 25 on the side wall of the outer tube 24 will squeeze the arc-shaped end 27 of the spring 26, and then push the fixing block 11 out of the perforation 21. After lamination is completed, the internal pressure of the vacuum laminator body 1 will gradually return to the same level as the external air pressure. As a result, the gas inside the sealing tube 9 will gradually return to its initial volume, the piston 10 will be pulled back to its original position, and the inner tube 23 fixedly connected to it will also return to its original position. However, due to the restriction of the spring 26, the outer tube 24 will still remain extended. After opening the closed door 3, start the dual-axis motor 13. The swing of the cleaning plate 14 will cause the clamp 16 to be locked into the fixing hole 22, thereby pulling the semi-enclosed frame 8 and the substrate 6 back into the slide 5. Then, the processed substrate 6 is transported to a position that is convenient for the staff to pick up by the drive inside the push table 2.

[0039] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
