Technical Field

[0001] The invention relates to the technical field of photovoltaic panels, in particular to a pressing device for producing photovoltaic panels. Background Art

[0002] Photovoltaic panel assembly is a power generation device that generates direct current when exposed to sunlight. In the photovoltaic panel preparation process, the photovoltaic panel cells need to be laminated, and a laminator is required in this step.

[0003] In this regard, China's patent application number: CN202211620250.6 discloses a laminator, which relates to the technical field of photovoltaic panel manufacturing, and includes an upper cover, a lower pressing frame is provided on one side of the upper cover, a connecting component is provided between the upper cover and the lower pressing frame, an upper pressing frame parallel to the lower pressing frame is provided on the side of the upper cover close to the lower pressing frame, a connecting shell connecting the upper pressing frame and the upper cover is provided between the upper pressing frame and the upper cover, and an adjustment component for adjusting the internal area is provided on both the lower pressing frame and the upper pressing frame. This application has the effect of quickly adjusting the internal size of the lower pressing frame, reducing production costs, and being able to quickly adapt to production work, thereby improving production efficiency.

[0004] The laminator installs adjustment components in the upper and lower pressing frames. When in use, the adjustment components in the upper pressing frame press down the rubber sheet so that the rubber sheet fits the adjustment components in the lower pressing frame, and the photovoltaic panels in the lower pressing frame can be laminated. Therefore, it is necessary to ensure that the positions of the adjustment components installed in the upper and lower pressing frames correspond to each other. However, the two sets of adjustment components are manually operated and there is no connection between them. During operation, it is difficult to ensure that the positions of the two sets of adjustment components correspond, resulting in a deviation between the size of the rubber sheet and the size of the photovoltaic panel, which will affect the lamination effect of the rubber sheet on the lower photovoltaic panel.

[0005] Therefore, in order to solve the above problems, a pressing device for producing photovoltaic panels is proposed. Summary of the invention

[0006] The object of the present invention is to provide a pressing device for photovoltaic panel production to solve the problem that the laminating machine in the prior art proposed in the above background technology installs adjustment components in the upper and lower pressing frames. When in use, the adjustment components in the upper pressing frame press down the rubber sheet so that the rubber sheet fits the adjustment components in the lower pressing frame, and the photovoltaic panels in the lower pressing frame can be laminated. Therefore, it is necessary to ensure that the positions of the adjustment components installed in the upper and lower pressing frames correspond to each other, and the two groups of adjustment components are manually operated and there is no connection between them. During operation, it is difficult to ensure that the positions of the two groups of adjustment components correspond, resulting in a deviation between the size of the rubber sheet and the size of the photovoltaic panel, which will affect the lamination effect of the rubber sheet on the lower photovoltaic panel.

The end of the guide column is fixedly connected with a vertical guide frame, and a movable frame is sleeved on the upper end of the vertical guide frame, and the end of the movable frame is fixedly connected with the upper pressure rod;

[0009] A regular structure is installed on the bottom surface of the upper pressure frame, and the regular structure includes an installation frame, which is fixedly installed on the bottom surface of the upper pressure frame, and the left and right side walls of the installation frame are fixedly connected to limit frames, and a rubber plate is fixedly installed on the inner side of the limit frame through abutment bolts, and a pull belt is fixedly connected to the top surface of the rubber plate. A threaded column is movably installed on the inner wall of the installation frame through a bearing, and a driving motor is threadedly connected to the threaded column, and a U-shaped sliding rod is fixedly installed on the inner wall of the installation frame.

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

[0011] Preferably, the lower pressure rod and the upper pressure rod are respectively provided with four groups and aligned up and down, the guide column and the movable rod both penetrate 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 pressure block is located on the upper side of the movable rod, and the bottom surface of the friction pressure block is tightly fitted with the surface of the movable rod, and the sprocket and the guide wheel are engaged with the chain.

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

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

[0015] Preferably, the U-shaped sliding rod provides power for the rotation of the threaded column, and the middle part of the driving motor is inserted into the interior of the drawstring.

[0016] Compared with the prior art, the beneficial effect of the present invention is that the pressing device of the present invention can make the positions of the lower pressing rod in the lower pressing frame and the upper pressing rod in the upper pressing frame always consistent with each other, through the cooperation of the vertical guide frame and the movable frame, and can ensure that the rubber sheet on the lower side of the upper pressing rod can just fit the upper surface of the photovoltaic panel, so as to facilitate the pressing of the photovoltaic panel through the rubber sheet.

[0017] An adjustment structure and a regular structure are provided, the worm is rotated, the worm is meshed with the worm wheel, the rotation of the worm drives the guide wheel to rotate through the worm wheel, the guide wheel drives the chain transmission, the chain is meshed with the sprocket, the chain transmission drives the threaded rod to rotate through the sprocket, the friction pressure block at the lower end of the threaded rod is threadedly connected, the rotation of the threaded rod drives the friction pressure block to rise in the lower pressure frame, so that the friction pressure block moves upward away from the movable rod, the movable rod is released, and the movable rod moves in the lower pressure frame under the action of the spring, so that the four groups of lower pressure rods are respectively attached to the four sides of the photovoltaic panel, and the photovoltaic panel can be restricted to the inner side of the lower pressure frame;

[0018] Then, the worm is rotated in the opposite direction, and the threaded rod is driven to reverse through the worm wheel, guide wheel, chain, and sprocket. The threaded rod drives the friction pressure block to descend and fit the movable rod, and the movable rod can be fixed to the lower pressing frame, so that the position of the photovoltaic panel inside the lower pressing frame is fixed;

[0019] When the upper pressing frame approaches the lower pressing frame downward, the movable frame can move downward on the outer side of the vertical guide frame. When the lower pressing rod moves inside the lower pressing frame, the guide column can be driven to move on the surface of the lower pressing frame. The guide column drives the vertical guide frame and the movable frame to move. The movable frame moves on the surface of the upper pressing frame and drives the upper pressing rod to move in the upper pressing frame, so that the upper pressing rod in the upper pressing frame and the lower pressing rod in the lower pressing frame always correspond to each other in the upper and lower positions. When the rubber sheet is pressed down by the upper pressing rod so that the rubber sheet fits the photovoltaic panel inside the lower pressing rod, the size of the rubber sheet located on the inner side of the upper pressing rod is consistent with the size of the photovoltaic panel in the lower pressing rod, so as to ensure the pressing effect of the photovoltaic panel by the rubber sheet;

[0020] After the pressing is completed, the upper pressing frame rises, driving the lower pressing frame upward and away from the guide rod, and the rubber sheet will produce a certain adhesion with the lower pressing rod and the photovoltaic panel, so that when the lower pressing frame rises, the part of the rubber sheet located at the lower side of the installation frame will be deformed to form a "V" shape. At this time, the U-shaped sliding rod can be started to drive the threaded column to rotate, and the threaded column is threadedly connected to the driving motor. The rotation of the threaded column drives the driving motor to move linearly inside the installation frame. Since the middle part of the driving motor is located inside the drawstring on the top surface of the rubber sheet, the driving motor will pull the drawstring when moving, and pull the rubber sheet through the drawstring, so that the deformed part of the rubber sheet is separated from the lower pressing rod and the photovoltaic panel, and the rubber sheet can be quickly restored. This can reduce the influence of the adhesion between the rubber sheet and the lower pressing rod and the photovoltaic panel on the installation stability of both ends of the rubber sheet when the upper pressing frame is separated from the lower pressing frame, and can avoid loosening of the installation of the rubber sheet, thereby ensuring the operating stability of the device.

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, and 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 positions of 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 consistent, which can ensure that the rubber sheet 33 on the lower side of the upper pressure rod 214 can just fit the upper surface of the photovoltaic panel, so that the photovoltaic panel can be pressed by the rubber sheet 33;

[0035] The bottom surface of the upper pressing frame 11 is installed with a regular structure 3, and the regular structure 3 includes a mounting frame 31, and the mounting frame 31 is fixedly installed on the bottom surface of the upper pressing frame 11. The left and right side walls of the mounting frame 31 are fixedly connected to the limit frame 32, and the inner side of the limit frame 32 is fixedly installed with a rubber plate 33 through abutment bolts 35. The top surface of the rubber plate 33 is fixedly connected with a pull belt 34. A threaded column 36 is movably installed on the inner wall of the mounting frame 31 through a bearing, and a driving motor 37 is threadedly connected to the threaded column 36. The inner wall of the mounting frame 31 is fixedly installed There is a U-shaped slide bar 38. Starting the U-shaped slide bar 38 can drive the driving motor 37 to move in the pull belt 34, so that the pull belt 34 is reset in the installation frame 31, and the deformed part of the rubber plate 33 can be separated from the lower pressure rod 21 and the photovoltaic panel, so that the rubber plate 33 can be quickly restored. When the upper pressure frame 11 and the lower pressure frame 12 are separated, the influence of the adhesion between the rubber plate 33 and the lower pressure rod 21 and the photovoltaic panel on the installation stability of the two ends of the rubber plate 33 can be reduced, and the loosening of the installation of the rubber plate 33 can be avoided, thereby ensuring the operating stability of the device.

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

[0037] Furthermore, four groups of the lower pressure rod 21 and the upper pressure rod 214 are respectively arranged and aligned up and down. The guide column 22 and the movable rod 23 all pass through the lower pressure frame 12. One end of the spring 24 is fixedly connected to the outer wall of the lower pressure frame 12. The guide column 22 cooperates with the movable rod 23 to limit the movable guide of the lower pressure rod 21 in the lower pressure frame 12, so that the lower pressure rod 21 can move straight. The spring 24 provides power for the movable rod 23 to move toward the inner side of the lower pressure frame 12, so as to drive the lower pressure rod 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, the friction pressure block 27 is located on the upper side of the movable rod 23, and the bottom surface of the friction pressure block 27 is tightly fitted with the surface of the movable rod 23, the sprocket 26 and the guide wheel 29 are engaged with the chain 28, and the rotation of the threaded rod 25 can drive the friction pressure block 27 to move up and down to fit into or away from the movable rod 23, so that the movable rod 23 is fixed or moved, and the four groups of lower pressure rods 21 can move at the same time, which can ensure the convenience of operation of the device.

[0039] Furthermore, the worm 211 is meshed 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 on the inner side of the installation frame 31. The rotating worm 211 can drive the guide wheel 29 to rotate through the worm wheel 210, so that the chain 28 is transmitted to provide power for the rotation of the threaded rod 25. When the upper pressure frame 11 approaches or moves away from the lower pressure frame 12, the movable frame 213 can move on the outside of the vertical guide frame 212. When the lower pressure rod 21 moves in the lower pressure frame 12, the upper pressure rod 214 can be driven to move in the upper pressure frame 11 through the guide column 22, the vertical guide frame 212 and the movable frame 213 to ensure that the lower pressure rod 21 and the upper pressure rod 214 are aligned up and down to ensure the squeezing effect on the rubber sheet 33.

[0040] Furthermore, the two ends of the rubber plate 33 are respectively located inside the two sets of limit frames 32, the abutment bolts 35 are threadedly connected to the limit frames 32, and the ends of the abutment bolts 35 abut against the rubber plate 33. The abutment bolts 35 can be used to fix the rubber plate 33 in the limit frames 32, so that the rubber plate 33 can be easily disassembled and assembled, thereby ensuring the convenience of replacing the rubber plate 33.

[0041] Furthermore, the U-shaped slide bar 38 provides power for the rotation of the threaded column 36. The middle part of the drive motor 37 is inserted into the interior of the drawstring 34. The threaded column 36 is threadedly connected to the drive motor 37. The rotation of the threaded column 36 can drive the drive motor 37 to move in the drawstring 34. When the rubber plate 33 is deformed, the drawstring 34 can be pulled to straighten the drawstring 34 in the installation frame 31. The drawstring 34 pulls the rubber plate 33 to reset the rubber plate 33 in the installation frame 31. It can assist in separating the rubber plate 33 from the lower pressure rod 21 and the photovoltaic panel to reduce the impact on the stability of the connection between the two ends of the rubber plate 33, thereby improving the practicability of the device.

[0042] Working principle: When in use, the photovoltaic panel is placed on the lower side of the lower pressing frame 12, the connecting cover 1 is lowered, driving the upper pressing frame 11 and the lower pressing frame 12 to descend, the lower pressing frame 12 is surrounded by the outer side of the photovoltaic panel and supported by the support below, the connecting cover 1 drives the upper pressing frame 11 to continue to descend, and the connecting cover 1 slides on the guide rod 13, so that the lower pressing frame 12 fits with the rubber plate 33;

[0043] The worm 211 is rotated, and the worm 211 is meshed with the worm wheel 210. The rotation of the worm 211 drives the guide wheel 29 to rotate through the worm wheel 210, and the guide wheel 29 drives the chain 28 to transmit. The chain 28 is meshed with the sprocket 26. The transmission of the chain 28 drives the threaded rod 25 to rotate through the sprocket 26. The friction pressure block 27 at the lower end of the threaded rod 25 is threadedly connected. The rotation of the threaded rod 25 drives the friction pressure block 27 to rise in the lower pressing frame 12, so that the friction pressure block 27 moves upward away from the movable rod 23, and the movable rod 23 is released. The movable rod 23 moves in the lower pressing frame 12 under the action of the spring 24, so that the four groups of lower pressing rods 21 are respectively attached to the four sides of the photovoltaic panel, and the photovoltaic panel can be restricted to the inner side of the lower pressing frame 12;

[0044] Then, the worm 211 is rotated in the reverse direction, and the threaded rod 25 is driven to reverse through the worm wheel 210, the guide wheel 29, the chain 28, and the sprocket 26. The threaded rod 25 then drives the friction block 27 to descend and fit the movable rod 23, and the movable rod 23 can be fixed to the lower pressing frame 12, so that the position of the photovoltaic panel inside the lower pressing frame 12 is fixed;

[0045] When the upper pressing frame 11 moves downwardly toward the lower pressing frame 12, the movable frame 213 can move downwardly on the outer side of the vertical guide frame 212. When the lower pressing rod 21 moves inside the lower pressing frame 12, the guide column 22 can be driven to move on the surface of the lower pressing 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 pressing frame 11 and drives the upper pressing rod 214 to move inside the upper pressing frame 11, so that the upper pressing rod 214 in the upper pressing frame 11 and the lower pressing rod 21 in the lower lower pressing frame 12 always correspond to each other in the upper and lower positions. When the rubber sheet 33 is pressed down by the upper pressing rod 214, so that the rubber sheet 33 fits the photovoltaic panel inside the lower pressing rod 21, the size of the rubber sheet 33 located on the inner side of the upper pressing rod 214 is consistent with the size of the photovoltaic panel in the lower pressing rod 21, which can ensure the pressing effect of the rubber sheet 33 on the photovoltaic panel.

[0046] After the pressing is completed, the upper pressing frame 11 rises, driving the lower pressing frame 12 upward and away from the guide rod 13, and the rubber sheet 33 will produce a certain adhesion with the lower pressing rod 21 and the photovoltaic panel, so that when the lower pressing frame 12 rises, the part of the rubber sheet 33 located at the lower side of the installation frame 31 will be deformed to form a "V" shape. At this time, the U-shaped sliding rod 38 can be started to drive the threaded column 36 to rotate. The threaded column 36 is threadedly connected to the drive motor 37. The rotation of the threaded column 36 drives the drive motor 37 to move linearly inside the installation frame 31. The middle part of 37 is located inside the drawstring 34 on the top surface of the rubber sheet 33. Therefore, when the driving motor 37 moves, it will pull the drawstring 34 and pull the rubber sheet 33 through the drawstring 34, so that the deformed part of the rubber sheet 33 is separated from the lower pressure rod 21 and the photovoltaic panel, and the rubber sheet 33 can be quickly restored. This can reduce the influence of the adhesion between the rubber sheet 33 and the lower pressure rod 21 and the photovoltaic panel on the installation stability of the two ends of the rubber sheet 33 when the upper pressure frame 11 is separated from the lower pressure frame 12, and can avoid the installation of the rubber sheet 33 from being loose, thereby ensuring the operating stability of the device.

Any ordinary technician in the industry can smoothly implement the present invention as shown in the drawings and described above. However, any equivalent changes, modifications and evolutions made by technicians familiar with the profession without departing from the scope of the technical solution of the present invention using the technical content disclosed above are all equivalent embodiments of the present invention. At the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the present invention are still within the protection scope of the technical solution of the present invention.
