Description

Technical Field

[0001] This invention relates to the field of photovoltaic panel technology, specifically to a pressing device for photovoltaic panel production. Background Technology

[0002] A photovoltaic (PV) panel is a power generation device that generates direct current (DC) when exposed to sunlight. In the manufacturing process of PV panels, the PV cells need to be laminated, and a laminator is required for this step.

[0003] In response, Chinese patent application number CN202211620250.6 discloses a laminating machine, relating to the technical field of photovoltaic panel manufacturing. It includes an upper cover, a lower pressing frame on one side of the upper cover, a connecting component between the upper cover and the lower pressing frame, an upper pressing frame parallel to the lower pressing frame on the side of the upper cover near the lower pressing frame, a connecting shell connecting the upper pressing frame and the upper cover, and adjustment components for adjusting the internal area on both the lower and upper pressing frames. This application allows for rapid adjustment of the internal dimensions of the lower pressing frame, reducing production costs and enabling rapid adaptation to production operations, thereby improving production efficiency.

[0004] This laminator uses adjusting components installed in upper and lower pressure frames. During use, the adjusting components in the upper pressure frame press down on the adhesive sheet, causing the adhesive sheet to adhere to the adjusting components in the lower pressure frame, thus laminating the photovoltaic panels in the lower pressure frame. Therefore, it is necessary to ensure that the positions of the adjusting components installed in the upper and lower pressure frames correspond vertically. However, both sets of adjusting components are manually operated and are not connected. During operation, it is difficult to ensure that the positions of the two sets of adjusting components correspond, resulting in a deviation between the size of the adhesive sheet and the size of the photovoltaic panel. This affects the lamination effect of the adhesive sheet on the photovoltaic panel below.

[0005] Therefore, in order to solve the above problems, a pressing device for photovoltaic panel production is proposed. Summary of the Invention

[0006] The purpose of this invention is to provide a pressing device for photovoltaic panel production, which solves the problem mentioned in the background art of the prior art laminator, which installs adjustment components in the upper and lower pressing frames. During use, the adjustment components in the upper pressing frame press down on the adhesive sheet, so that the adhesive sheet adheres to the adjustment components in the lower pressing frame, and can laminate the photovoltaic panel in the lower pressing frame. Therefore, it is necessary to ensure that the positions of the adjustment components installed in the upper and lower pressing frames are vertically aligned. However, both sets of adjustment components are manually operated and are not connected. During operation, it is difficult to ensure that the positions of the two sets of adjustment components are aligned, resulting in a deviation between the size of the adhesive sheet and the size of the photovoltaic panel, which affects the lamination effect of the adhesive sheet on the lower photovoltaic panel.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a pressing device for photovoltaic panel production, comprising: a connecting cover, an upper pressing frame installed on the bottom surface of the connecting cover, a lower pressing frame installed on the lower side of the upper pressing frame, and a guide rod fixedly connected to the outer wall of the lower pressing frame;

[0008] An adjustment structure is installed on the upper and lower pressure frames. The adjustment structure includes a lower pressure rod, which is movably installed inside the lower pressure frame. A guide post and a movable rod are fixedly connected to the outer wall of the lower pressure rod. A spring is fixedly connected to the outer side of the movable rod. A threaded rod is movably installed inside the lower pressure frame via bearings. A sprocket is fixedly connected to the upper end of the threaded rod, and a friction block is threadedly connected to the lower end of the threaded rod. A chain is sleeved on the outer side of the sprocket. Four sets of guide wheels are movably installed at the four corners of the lower pressure frame via bearings. A worm gear is fixedly installed in the middle of one set of guide wheels. A worm is movably installed on the outer wall of the lower pressure rod via bearings. A vertical guide frame is fixedly connected to the end of the guide post. A movable frame is sleeved on the outer side of the upper end of the vertical guide frame. An upper pressure rod is fixedly connected to the end of the movable frame.

[0009] The bottom surface of the upper pressure frame is equipped with a regular structure, which includes a mounting frame. The mounting frame is fixedly installed on the bottom surface of the upper pressure frame. Limiting frames are fixedly connected to the left and right side walls of the mounting frame. A rubber plate is fixedly installed on the inner side of the limiting frame by abutment bolts. A pull strap is fixedly connected to the top surface of the rubber plate. A threaded column is movably installed on the inner wall of the mounting frame through a bearing. A U-shaped slide rod is threadedly connected to the threaded column. A drive motor is fixedly installed on the inner wall of the mounting frame.

[0010] Preferably, the upper end of the guide rod passes through the connecting cover, and the upper pressure frame and the lower pressure frame are aligned vertically.

[0011] Preferably, there are four sets of lower pressure rods and upper pressure rods, which are aligned vertically. The guide post and the movable rod both pass through the lower pressure frame, and one end of the spring is fixedly connected to the outer wall of the lower pressure frame.

[0012] Preferably, the threaded rod is located on both sides of the movable rod, the friction block is located on the upper side of the movable rod, and the bottom surface of the friction block is in close contact with the surface of the movable rod, and the sprocket and guide wheel mesh with the chain.

[0013] Preferably, the worm gear meshes with the worm wheel, the vertical guide frame is installed vertically, the movable frame passes through the upper pressure frame, and the lower end of the upper pressure rod is located inside the mounting frame.

[0014] Preferably, the two ends of the rubber plate are located inside the two sets of limiting frames, the abutting bolt is threadedly connected to the limiting frame, and the end of the abutting bolt abuts against the rubber plate.

[0015] Preferably, the drive motor provides power for the rotation of the threaded column, and the middle part of the U-shaped slide rod passes through the inside of the pull belt.

[0016] Compared with the prior art, the beneficial effects of the present invention are: the pressing device of the present invention, through the cooperation of the vertical guide frame and the movable frame, can ensure that the lower pressing rod in the lower pressing frame and the upper pressing rod in the upper pressing frame are always in the same position, which can ensure that the adhesive plate on the lower side of the upper pressing rod can just fit against the upper surface of the photovoltaic panel, making it convenient to press the photovoltaic panel through the adhesive plate.

[0017] Equipped with an adjustment structure and a regularization structure, the rotating worm gear meshes with a worm wheel. The rotation of the worm gear drives the guide wheel to rotate through the worm wheel, which in turn drives the chain drive. The chain meshes with a sprocket, and the chain drive drives the threaded rod to rotate through the sprocket. The lower end of the threaded rod is threadedly connected to a friction block. The rotation of the threaded rod causes the friction block to rise within the lower pressure frame, moving it upward away from the movable rod. The movable rod is then released from its fixed position and moves within the lower pressure frame under the action of a spring. This allows the four sets of lower pressure rods to respectively conform to the four sides of the photovoltaic panel, thus confining the photovoltaic panel inside the lower pressure frame.

[0018] Next, the worm gear is rotated in the opposite direction, which drives the threaded rod to reverse through the worm wheel, guide wheel, chain, and sprocket. The threaded rod then drives the friction block to descend and fit against the movable rod, which can fix the movable rod in the lower pressure frame, so that the photovoltaic panel is fixed in the position inside the lower pressure frame.

[0019] Furthermore, when the upper pressure frame moves downwards towards the lower pressure frame, the movable frame can move downwards outside the vertical guide frame. When the lower pressure rod moves inside the lower pressure frame, it can drive the guide column to move on the surface of the lower pressure frame. The guide column then drives the vertical guide frame and the movable frame to move. The movable frame moves on the surface of the upper pressure frame and drives the upper pressure rod to move inside the upper pressure frame. This ensures that the upper pressure rod inside the upper pressure frame and the lower pressure rod inside the lower pressure frame always correspond in vertical position. This ensures that when the adhesive plate is pressed down by the upper pressure rod and adheres to the photovoltaic panel inside the lower pressure rod, the size of the part of the adhesive plate inside the upper pressure rod is consistent with the size of the photovoltaic panel inside the lower pressure rod. This guarantees the pressing effect of the adhesive plate on the photovoltaic panel.

[0020] After pressing, the upper pressure frame rises, causing the lower pressure frame to move upwards away from the guide rod. The adhesive sheet will adhere to the lower pressure rod and the photovoltaic panel, causing the portion of the adhesive sheet located under the mounting frame to deform into a "V" shape when the lower pressure frame rises. At this point, the drive motor can be started, rotating the threaded column. The threaded column is threadedly connected to the U-shaped slide rod. The rotation of the threaded column causes the U-shaped slide rod to move linearly inside the mounting frame. Since the middle of the U-shaped slide rod is located inside the pull strap on the top surface of the adhesive sheet, the U-shaped slide rod pulls the pull strap as it moves, which in turn pulls the adhesive sheet, causing the deformed portion of the adhesive sheet to separate from the lower pressure rod and the photovoltaic panel. This allows the adhesive sheet to quickly recover its original shape, reducing the impact of the adhesion between the adhesive sheet and the lower pressure rod and photovoltaic panel on the installation stability of both ends of the adhesive sheet when the upper and lower pressure frames separate. This prevents the adhesive sheet from becoming loose and ensures the operational stability of the device. Attached Figure Description

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figures 1-8 One embodiment provided by the present invention:

[0032] The connecting cover 1, upper pressure frame 11, lower pressure frame 12, guide rod 13 and U-shaped slide rod 37 used in this application are products that can be purchased directly on the market. Their principles and connection methods are existing technologies well known to those skilled in the art, so they will not be described in detail here.

[0033] A pressing device for photovoltaic panel production includes: a connecting cover 1, an upper pressing frame 11 installed on the bottom surface of the connecting cover 1, a lower pressing frame 12 installed on the lower side of the upper pressing frame 11, and a guide rod 13 fixedly connected to the outer wall of the lower pressing frame 12.

[0034] Adjustment structures 2 are installed on the upper pressure frame 11 and the lower pressure frame 12. The adjustment structure 2 includes a lower pressure rod 21, which is movably installed inside the lower pressure frame 12. A guide post 22 and a movable rod 23 are fixedly connected to the outer wall of the lower pressure rod 21. A spring 24 is fixedly connected to the outer side of the movable rod 23. A threaded rod 25 is movably installed inside the lower pressure frame 12 via bearings. A sprocket 26 is fixedly connected to the upper end of the threaded rod 25, and a friction block 27 is threadedly connected to the lower end of the threaded rod 25. A chain 28 is sleeved on the outer side of the sprocket 26. Four sets of guide wheels 29 are movably installed at the four corners inside the lower pressure frame 12 via bearings. A worm gear 210 is fixedly installed in the middle of the wheel 29. A worm 211 is movably installed on the outer wall of the lower pressure rod 21 through a bearing. A vertical guide frame 212 is fixedly connected to the end of the guide column 22. A movable frame 213 is sleeved on the outer side of the upper end of the vertical guide frame 212. An upper pressure rod 214 is fixedly connected to the end of the movable frame 213. Through the cooperation of the vertical guide frame 212 and the movable frame 213, the lower pressure rod 21 in the lower pressure frame 12 and the upper pressure rod 214 in the upper pressure frame 11 are always aligned vertically. This ensures that the adhesive plate 33 on the lower side of the upper pressure rod 214 can fit perfectly against the upper surface of the photovoltaic panel, making it easier to press the photovoltaic panel through the adhesive plate 33.

[0035] A regular structure 3 is installed on the bottom surface of the upper pressure frame 11. The regular structure 3 includes a mounting frame 31, which is fixedly installed on the bottom surface of the upper pressure frame 11. Limiting frames 32 are fixedly connected to the left and right side walls of the mounting frame 31. A rubber plate 33 is fixedly installed on the inner side of the limiting frame 32 by abutment bolts 35. A pull strap 34 is fixedly connected to the top surface of the rubber plate 33. A threaded column 36 is movably installed on the inner wall of the mounting frame 31 by bearings. A U-shaped slide rod 37 is threadedly connected to the threaded column 36. A fixed structure 36 is installed on the inner wall of the mounting frame 31. With a drive motor 38, starting the drive motor 38 can drive the U-shaped slide bar 37 to move within the pull strap 34, causing the pull strap 34 to reset within the mounting frame 31. This allows the deformed part of the adhesive plate 33 to separate from the lower pressure rod 21 and the photovoltaic panel, enabling the adhesive plate 33 to be quickly restored. This reduces the impact of the adhesion between the adhesive plate 33 and the lower pressure rod 21 and the photovoltaic panel on the installation stability of both ends of the adhesive plate 33 when the upper pressure frame 11 separates from the lower pressure frame 12, preventing the installation of the adhesive plate 33 from becoming loose, and thus ensuring the operational stability of the device.

[0036] Furthermore, the upper end of the guide rod 13 passes through the connecting cover 1, the upper pressure frame 11 and the lower pressure frame 12 are aligned vertically, and the upper pressure rod 214 in the upper pressure frame 11 can be aligned vertically with the lower pressure rod 21 in the lower pressure frame 12 to ensure the squeezing effect on the rubber plate 33.

[0037] Furthermore, four sets of lower pressure rods 21 and upper pressure rods 214 are respectively provided and aligned vertically. Guide posts 22 and movable rods 23 both penetrate the lower pressure frame 12. One end of spring 24 is fixedly connected to the outer wall of the lower pressure frame 12. Guide posts 22 and movable rods 23 guide and limit the movement of lower pressure rods 21 within the lower pressure frame 12, so that lower pressure rods 21 move in a straight line. Spring 24 provides power for movable rods 23 to move towards the inner side of the lower pressure frame 12, so as to drive lower pressure rods 21 to abut against the photovoltaic panel on the inner side of the lower pressure frame 12.

[0038] Furthermore, the threaded rod 25 is located on both sides of the movable rod 23, and the friction block 27 is located on the upper side of the movable rod 23. The bottom surface of the friction block 27 is in close contact with the surface of the movable rod 23. The sprocket 26 and the guide wheel 29 are engaged with the chain 28. The rotation of the threaded rod 25 can drive the friction block 27 to move up and down to fit or move away from the movable rod 23, so that the movable rod 23 is fixed or moved. Moreover, the four sets of downward pressing rods 21 can move simultaneously, which can ensure the ease of operation of the device.

[0039] Furthermore, the worm 211 meshes with the worm wheel 210, the vertical guide frame 212 is installed vertically, the movable frame 213 passes through the upper pressure frame 11, and the lower end of the upper pressure rod 214 is located inside the mounting frame 31. The rotating worm 211 can drive the guide wheel 29 to rotate through the worm wheel 210, so that the chain 28 can drive and provide power for the rotation of the threaded rod 25. When the upper pressure frame 11 is close to or away from the lower pressure frame 12, the movable frame 213 can move outside the vertical guide frame 212. When the lower pressure rod 21 moves inside the lower pressure frame 12, it can drive the upper pressure rod 214 to move inside the upper pressure frame 11 through the guide column 22, the vertical guide frame 212 and the movable frame 213, so as to ensure that the lower pressure rod 21 and the upper pressure rod 214 are aligned vertically and ensure the squeezing effect on the rubber plate 33.

[0040] Furthermore, the two ends of the rubber plate 33 are located inside the two sets of limiting frames 32 respectively. The abutting bolt 35 is threadedly connected to the limiting frame 32, and the end of the abutting bolt 35 abuts against the rubber plate 33. The rubber plate 33 can be fixed in the limiting frame 32 by the abutting bolt 35, which makes the disassembly and assembly of the rubber plate 33 convenient and ensures the ease of replacement of the rubber plate 33.

[0041] Furthermore, the drive motor 38 provides power for the rotation of the threaded column 36. The middle part of the U-shaped slide rod 37 passes through the inside of the pull belt 34. The threaded column 36 is threadedly connected to the U-shaped slide rod 37. The rotation of the threaded column 36 can drive the U-shaped slide rod 37 to move within the pull belt 34. When the rubber sheet 33 deforms, it can pull the pull belt 34, making the pull belt 34 taut within the mounting frame 31. The pull belt 34 then pulls the rubber sheet 33, causing the rubber sheet 33 to reset within the mounting frame 31. This can help separate the rubber sheet 33 from the lower pressure rod 21 and the photovoltaic panel, thereby reducing the impact on the stability of the connection at both ends of the rubber sheet 33 and improving the practicality of the device.

[0042] Working principle: When in use, the photovoltaic panel is placed under the lower pressure frame 12, the connecting cover 1 descends, which drives the upper pressure frame 11 and the lower pressure frame 12 to descend. The lower pressure frame 12 surrounds the outside of the photovoltaic panel and is supported by the support below. The connecting cover 1 drives the upper pressure frame 11 to continue to descend. The connecting cover 1 slides on the guide rod 13, so that the lower pressure frame 12 is in contact with the adhesive plate 33.

[0043] Rotating worm 211 meshes with worm wheel 210. The rotation of worm 211 drives guide wheel 29 to rotate through worm wheel 210. Guide wheel 29 drives chain 28 to drive the transmission. Chain 28 meshes with sprocket 26. The transmission of chain 28 drives threaded rod 25 to rotate through sprocket 26. The lower end of threaded rod 25 is threadedly connected to friction block 27. The rotation of threaded rod 25 drives friction block 27 to rise in the lower pressure frame 12, so that friction block 27 moves upward away from movable rod 23. Movable rod 23 is then released from fixation. Movable rod 23 moves in the lower pressure frame 12 under the action of spring 24, so that the four sets of lower pressure rods 21 respectively fit the four sides of photovoltaic panel, which can restrict photovoltaic panel inside the lower pressure frame 12.

[0044] Next, the worm gear 211 is rotated in the opposite direction, which drives the threaded rod 25 to reverse through the worm wheel 210, guide wheel 29, chain 28, and sprocket 26. The threaded rod 25 then drives the friction block 27 to descend and fit against the movable rod 23, which can fix the movable rod 23 on the lower pressure frame 12, so that the photovoltaic panel is fixed in the position inside the lower pressure frame 12.

[0045] When the upper pressure frame 11 moves downward toward the lower pressure frame 12, the movable frame 213 can move downward outside the vertical guide frame 212. When the lower pressure rod 21 moves inside the lower pressure frame 12, it can drive the guide column 22 to move on the surface of the lower pressure frame 12. The guide column 22 drives the vertical guide frame 212 and the movable frame 213 to move. The movable frame 213 moves on the surface of the upper pressure frame 11 and drives the upper pressure rod 214 to move inside the upper pressure frame 11, so that the upper pressure rod 214 inside the upper pressure frame 11 and the lower pressure rod 21 inside the lower pressure frame 12 always correspond in vertical position. This ensures that when the glue plate 33 is pressed down by the upper pressure rod 214 and the photovoltaic panel inside the lower pressure rod 21 is attached to the lower pressure rod 21, the size of the part of the glue plate 33 inside the upper pressure rod 214 is consistent with the size of the photovoltaic panel inside the lower pressure rod 21, thus ensuring the pressing effect of the glue plate 33 on the photovoltaic panel.

[0046] After pressing, the upper pressure frame 11 rises, causing the lower pressure frame 12 to move upwards away from the guide rod 13. The adhesive plate 33 will adhere to the lower pressure rod 21 and the photovoltaic panel, causing the portion of the adhesive plate 33 located under the mounting frame 31 to deform into a "V" shape when the lower pressure frame 12 rises. At this time, the drive motor 38 can be started to rotate the threaded column 36. The threaded column 36 is threadedly connected to the U-shaped slide rod 37. The rotation of the threaded column 36 causes the U-shaped slide rod 37 to move linearly inside the mounting frame 31. The middle part of 37 is located inside the pull strap 34 on the top surface of the adhesive plate 33. Therefore, when the U-shaped slide bar 37 moves, it will pull the pull strap 34 and pull the adhesive plate 33 through the pull strap 34, so that the deformed part of the adhesive plate 33 is separated from the lower pressure rod 21 and the photovoltaic panel. This allows the adhesive plate 33 to be quickly restored, which can reduce the impact of the adhesion between the adhesive plate 33 and the lower pressure rod 21 and the photovoltaic panel on the installation stability of both ends of the adhesive plate 33 when the upper pressure frame 11 and the lower pressure frame 12 are separated. This can prevent the installation of the adhesive plate 33 from becoming loose, thereby ensuring the operational stability of the device.
