Description

Technical Field

[0001] This invention relates to the field of photovoltaic module processing technology, and in particular to a device and method for disassembling photovoltaic module frames using a hydraulic cylinder. Background Technology

[0002] With the booming development of the photovoltaic industry, photovoltaic modules, as the core components that convert solar energy into electricity, have attracted much attention in terms of production and recycling. As the service life of photovoltaic modules increases, a large number of waste photovoltaic modules urgently need to be recycled and processed. Among them, the disassembly of the photovoltaic panel frame is one of the key steps in the recycling process.

[0003] Currently, in photovoltaic module dismantling production lines, the dismantling of photovoltaic panel frames mainly relies on manual operation or some simple mechanical tools. Manual dismantling has many drawbacks. On the one hand, manual operation is inefficient. Due to the large number of photovoltaic modules, manual dismantling cannot meet the needs of large-scale production, resulting in long recycling cycles and increasing the operating costs of enterprises. On the other hand, it is difficult to accurately control the precision and force of manual dismantling, which can easily damage the photovoltaic panels during the dismantling process, such as scratching the surface of the photovoltaic panels or causing the cells to crack. This not only reduces the recycling value of the photovoltaic panels but may also create safety hazards.

[0004] Existing simple mechanical tools also present several problems when disassembling photovoltaic panel frames. Some tools lack effective clamping and fixing mechanisms for the photovoltaic panels, causing them to wobble or shift during disassembly, affecting the smooth progress of the process and potentially preventing proper frame removal. In addition, some tools lack precision and stability in their disassembly actions, which may cause excessive pressure or pulling on the frame or photovoltaic panel when pushing it away from the panel, resulting in component damage. Furthermore, existing mechanical tools have poor versatility, often only applicable to photovoltaic panel frames of specific sizes. When dealing with photovoltaic panels of different sizes, different tools or complex adjustments are required, increasing the complexity and cost of the operation.

[0005] In addition, protecting the photovoltaic panel and the frame is also crucial during the disassembly process of the photovoltaic panel frame. The existing disassembly methods are insufficient in terms of protection. During the disassembly process, the photovoltaic panel is usually clamped and then the frame is pulled. During the pulling process, the photovoltaic panel is prone to breakage and cannot be effectively recycled. Summary of the Invention

[0006] The purpose of this invention is to address the aforementioned shortcomings in the prior art by proposing a hydraulic cylinder device and method for disassembling photovoltaic module frames.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A hydraulic cylinder device for disassembling photovoltaic module frames, used in a photovoltaic module disassembly production line, for disassembling photovoltaic modules, comprising:

[0009] The gripper motherboard is connected to the production line support via a connector;

[0010] The gripper body is adjustable on one side of the gripper main board. The gripper body is C-shaped. Dovetail blocks are slidably provided on both sides of the gripper body. One side of each of the two dovetail blocks is bolted to the same pressure block located inside the gripper body.

[0011] The first hydraulic cylinder is bolted to the gripper body. The output end of the first hydraulic cylinder is fixedly connected to the pressure block. The first hydraulic cylinder drives the pressure block to move closer to the bottom of the gripper body to clamp the photovoltaic panel.

[0012] A fixing mechanism is provided on the pressure block, including a third hydraulic cylinder, a second clamping block and a first clamping block. The output end of the third hydraulic cylinder is fixedly provided with the second clamping block. A first clamping block corresponding to the second clamping block is provided on one side of the pressure block. The third hydraulic cylinder drives the second clamping block to move closer to the first clamping block to fix the frame on one side.

[0013] The pushing mechanism is located on one side of the pressure block and includes a second hydraulic cylinder and a push plate. The push plate is fixed at the output end of the second hydraulic cylinder. The second hydraulic cylinder drives the push plate to move outward, pushing one side of the Y-axis frame away from the photovoltaic panel.

[0014] As a further improvement to the above technical solution:

[0015] Two first guide rails are bolted to one side of the gripper main board, and the gripper body is slidably sleeved on the two first guide rails;

[0016] Two mounting slots are provided on one side of the gripper main board. A connecting plate is welded in the mounting slot. A second cylinder is bolted between the two connecting plates. The output end of the second cylinder is fixedly connected to the gripper body. The second cylinder drives the gripper body to move up and down, so that the bottom wall of the gripper body contacts the photovoltaic panel.

[0017] The fixing mechanism also includes a second guide rail bolted to one side of the pressure block, an L-shaped body slidably mounted on the second guide rail, a third hydraulic cylinder bolted inside the L-shaped body, and a first clamping block bolted to one side of the L-shaped body.

[0018] A connector is fixedly provided through one side of the second clamping block, and one end of the connector is fixedly connected to the output end of the third hydraulic cylinder;

[0019] The top of the L-shaped body is provided with a first dovetail groove, and a fourth guide rail is slidably provided in the first dovetail groove. The second clamping block is L-shaped, and one side of it is fixedly connected to the fourth guide rail with a bolt.

[0020] The second hydraulic cylinder is bolted and fixedly connected inside the body of component L;

[0021] The L-shaped body is bolted to a third guide rail, and the push plate is slidably sleeved on the third guide rail.

[0022] At least two limiting strips are fixedly provided on the top of the pressure block to limit the L-shaped body.

[0023] The bottom of the pressure block and the bottom wall of the gripper body are both provided with grooves, and silicone pads are bolted into the grooves.

[0024] A second mounting plate is bolted to one side of the gripper main board, and a first cylinder is bolted to one side of the second mounting plate. The output end of the first cylinder extends to the other side of the second mounting plate and is threaded with a rubber head.

[0025] The method for using a hydraulic cylinder to disassemble a photovoltaic module frame, applied in the aforementioned hydraulic cylinder device for disassembling photovoltaic module frames, includes the following steps:

[0026] S1. The gripper body is driven to move up and down by the second cylinder, so that the bottom wall of the gripper body contacts the photovoltaic panel;

[0027] S2. Start the first hydraulic cylinder to drive the pressure block to move closer to the bottom of the gripper body to clamp the photovoltaic panel, and position the second clamping block at the height of the first clamping block;

[0028] S3. Start the third hydraulic cylinder to drive the second clamping block to move closer to the first clamping block, fix the frame, and position the push plate.

[0029] S4. Start the second hydraulic cylinder to drive the push plate to move outward, pushing one side of the Y-axis frame away from the photovoltaic panel;

[0030] S5. Start the first cylinder to drive the rubber head to move closer to the frame, pushing the frame out of the gripper body.

[0031] In this invention, the hydraulic cylinder disassembling device for photovoltaic modules utilizes a gripper body that is adjustable on one side of the gripper main board and dovetail blocks that slide on both sides of the gripper body. This, combined with the first hydraulic cylinder driving the pressure block towards the bottom of the gripper body, enables stable clamping of the photovoltaic panel. The gripper body has a C-shaped design, providing reasonable space for the movement of the pressure block. The connection between the pressure block and the dovetail blocks ensures the smoothness of the clamping action. This design is not only easy to operate but also allows for precise control of the clamping force, effectively preventing damage to the photovoltaic panel during clamping. This improves the safety of the photovoltaic panel during disassembly, reduces the scrap rate, and saves production costs for enterprises. Furthermore, the force is concentrated in the gripper area, preventing the disassembly force from being transmitted to the machine tool frame, thus enabling a lighter machine tool bed.

[0032] In this invention, the hydraulic cylinder disassembling device for photovoltaic module frames utilizes a third hydraulic cylinder to drive the second clamping block closer to the first clamping block, reliably fixing the X-axis frame of one side of the photovoltaic panel. The cooperation between the first and second clamping blocks ensures a more secure fixation of the frame, preventing loosening or displacement during subsequent disassembly. Simultaneously, the fixing mechanism, through the sliding connection between the second guide rail and the L-shaped main body, and the fixed connection between the second clamping block and the fourth guide rail, guarantees the accuracy and stability of the fixing action. This allows the device to adapt to photovoltaic panel frames of different specifications, improving its versatility and applicability. It reduces the cost and time for companies to replace equipment when changing photovoltaic panels of different specifications. The frame clamping mechanism components are connected in series via dovetail guide rails, enabling mechanical self-floating adjustment of position without the need for additional sensors and drive modules, simplifying the structure.

[0033] In this invention, the hydraulic cylinder disassembly device for photovoltaic module frames uses a second hydraulic cylinder to drive a push plate to move outward, effectively pushing the Y-axis frame away from the photovoltaic panel and the X-axis frame. The fixed connection between the push plate and the output end of the second hydraulic cylinder, as well as the sliding connection of the push plate on the third guide rail, ensures the stability and accuracy of the push plate's movement. This allows for quick and efficient separation of the frame from the photovoltaic panel, greatly improving disassembly efficiency, shortening the production cycle, and thus increasing the company's production efficiency. Simultaneously, during the disassembly process, the force on the photovoltaic panel is concentrated on the edge of the clamped frame, without exerting force on the main body of the photovoltaic panel, thereby protecting the photovoltaic panel from secondary breakage.

[0034] In this invention, the hydraulic cylinder disassembling device for photovoltaic module frames includes a second mounting plate connected to one side of the gripper main board by bolts, and a first cylinder and a rubber head with threads on the output end of the first cylinder connected to the second mounting plate by bolts. After disassembly, the Y-axis frame inside the gripper body can be pushed out, providing additional auxiliary functions for the device. Attached Figure Description

[0042] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0043] Example 1

[0044] Reference Figures 1-6 The hydraulic cylinder-based photovoltaic module frame disassembly device is used in the photovoltaic module disassembly production line. It is primarily used to disassemble the frame 14 of the photovoltaic panel 13 (consisting of two X-axis frames and two Y-axis frames). The entire device is fixedly mounted on the production line support via a connecting seat 2, ensuring stability during operation.

[0045] The core component of the device is the gripper mainboard 1. Two first guide rails 24 are bolted to one side of the gripper mainboard 1. The gripper body 19 is slidably mounted on the two first guide rails 24, allowing the gripper body 19 to move up and down on one side of the gripper mainboard 1. Two mounting slots 23 are provided on one side of the gripper mainboard 1. Connecting plates 6 are welded into the mounting slots 23. A second cylinder 7 is bolted between the two connecting plates 6, and the output end of the second cylinder 7 is fixedly connected to the gripper body 19. In actual operation, when it is necessary to adjust the height of the gripper body 19, the second cylinder 7 is activated. The output end of the second cylinder 7 extends or retracts, thereby driving the gripper body 19 to move up and down along the first guide rails 24, so that the bottom wall of the gripper body 19 can accurately contact the photovoltaic panel 13.

[0046] Meanwhile, a limiting block 20 located below the gripper body 19 is also connected to one side of the gripper main board 1 by bolts, which ensures that the gripper body 19 will not detach from the gripper main board 1 during movement.

[0047] The gripper body 19 is C-shaped, with dovetail blocks 10 slidingly mounted on both sides. One side of each dovetail block 10 is bolted to a pressure block 9 located within the gripper body 19. A first hydraulic cylinder 8 is bolted to the gripper body 19, and its output end is fixedly connected to the pressure block 9. When clamping the photovoltaic panel 13, the first hydraulic cylinder 8 is activated, and its output end pushes the pressure block 9 closer to the bottom of the gripper body 19. Because the pressure block 9 is connected to the dovetail blocks 10 on both sides of the gripper body 19, the movement of the pressure block 9 is ensured. The position can be adjusted by self-floating using the dovetail blocks 10, eliminating the need for additional sensors and drive modules, thus simplifying the structure. When the pressure block 9 engages with the bottom wall of the gripper body 19, it can firmly clamp the photovoltaic panel 13.

[0048] A fixing mechanism is provided on the pressure block 9. This fixing mechanism includes a second guide rail 28 bolted to one side of the pressure block 9. An L-shaped body 11 is slidably mounted on the second guide rail 28, allowing the L-shaped body 11 to slide on the second guide rail 28. A third hydraulic cylinder 15 is bolted to the L-shaped body 11. A first clamping block 16 is bolted to one side of the L-shaped body 11. A connector 17 is fixedly mounted through one side of the second clamping block 18. One end of the connector 17 is fixedly connected to the output end of the third hydraulic cylinder 15, enabling the third hydraulic cylinder 15 to drive the second clamping block 18 to move. A first dovetail groove 30 is formed on the top of the L-shaped body 11. A fourth guide rail 31 is slidably mounted within the first dovetail groove 30. The second clamping block 18 is L-shaped, and one side of it is fixedly connected to the fourth guide rail 31 by bolts, ensuring the stability of the movement of the second clamping block 18. When it is necessary to fix the X-axis frame 14 on one side of the photovoltaic panel 13, the third hydraulic cylinder 15 is activated. The output end of the third hydraulic cylinder 15 pushes the second clamping block 18 along the fourth guide rail 31 toward the first clamping block 16, thereby clamping and fixing the X-axis frame 14 between the first clamping block 16 and the second clamping block 18.

[0049] A pushing mechanism is also provided on one side of the pressure block 9. This pushing mechanism includes a second hydraulic cylinder 12 and a push plate 27. The second hydraulic cylinder 12 is fixedly connected to the L-shaped body 11 by bolts. A third guide rail 29 is bolted to the L-shaped body 11. The push plate 27 is slidably sleeved on the third guide rail 29 to ensure the smooth movement of the push plate 27. When it is necessary to detach the Y-axis frame 14 from the photovoltaic panel 13 and the Y-axis frame 14, the second hydraulic cylinder 12 is activated. The output end of the second hydraulic cylinder 12 pushes the push plate 27 to move outward along the third guide rail 29. The push plate 27 contacts the Y-axis frame 14 and applies a pushing force, so that one side of the Y-axis frame 14 detaches from the photovoltaic panel 13 and the Y-axis frame 14. At the same time, the bottom thickness of the push plate 27 is less than the width of the groove of the frame 14, so that the push plate 27 can be inserted into the frame 14 during the pushing process.

[0050] In addition, a second mounting plate 3 is bolted to one side of the gripper main board 1. A first cylinder 4 is bolted to one side of the second mounting plate 3. The output end of the first cylinder 4 extends to the other side of the second mounting plate 3 and is threaded with a rubber head 5. When it is necessary to remove the frame 14 from the gripper body 19, the first cylinder 4 is activated to extend. During the extension process, the rubber head 5 can be driven to move closer to the frame 14, thereby pushing the Y-axis frame 14 out of the gripper body 19.

[0051] This application can be used in the field of photovoltaic module processing, or in other fields applicable to this application.

[0052] Example 2

[0053] refer to Figures 1-6The hydraulic cylinder disassembly device for photovoltaic module frames is applied in the field of photovoltaic module processing. To prevent damage to the photovoltaic panel 13 during the clamping process, grooves 21 are provided at the bottom of the pressure block 9 and the bottom wall of the gripper body 19. A silicone pad 22 is connected to the groove 21 by bolts. The silicone pad 22 has good cushioning performance and can effectively protect the photovoltaic panel 13. The silicone pad 22 is made of flame-retardant material with a Shore hardness of 60A and has anti-slip texture pressed on the surface.

[0054] To prevent the L-shaped body 11 from moving beyond the predetermined range, at least two limiting strips 26 are fixedly provided on the top of the pressure block 9 to limit the L-shaped body 11. At the same time, an inclined support strip 32 is also connected to one side of the L-shaped body 11 by bolts to strengthen the L-shaped body 11.

[0055] Meanwhile, four reinforcing ribs 25 are connected to the first hydraulic cylinder 8, the second hydraulic cylinder 12, and the third hydraulic cylinder 15 to increase their rigidity. They are also connected to an external hydraulic station through pipes, and their extension and retraction are controlled by the hydraulic station.

[0056] In use, the photovoltaic panel 13 is conveyed to the gripper body 19 by the conveyor, and the second cylinder 7 is activated to extend and retract, so that the silicone pad 22 on the bottom wall of the gripper body 19 contacts the photovoltaic panel 13.

[0057] The first hydraulic cylinder 8 is activated to extend, driving the pressure block 9 to move downward, so that the silicone pad 22 at the bottom of the pressure block 9 abuts against the top of the photovoltaic panel 13, clamping the photovoltaic panel 13. At the same time, the pressure block 9 can drive the L-shaped body 11 to move downward, so that the first clamping block 16, the second clamping block 18 and the push plate 27 can move to one side of the X-axis frame 14. After clamping is completed, the first hydraulic cylinder 8 is activated to retract, driving the pressure block 9 to move upward until the silicone pad 22 at the bottom of the pressure block 9 no longer contacts the photovoltaic panel 13, so that there is a 2mm gap between the silicone pad 22 at the bottom of the pressure block 9 and the photovoltaic panel 13, and so that the push plate 27 can abut against the internal rubber strip during the movement.

[0058] The third hydraulic cylinder 15 is activated to retract. During the retraction process, the connector 17 can drive the second clamping block 18 to move towards the L-shaped body 11. When the second clamping block 18 touches the X-axis frame 14 on one side, the L-shaped body 11 moves towards the second clamping block 18 with the second clamping block 18 as the reference, driving the first clamping block 16 to move towards the second clamping block 18 to clamp the X-axis frame 14. During the movement, the L-shaped body 11 can drive the push plate 27 to move, so that the push plate 27 moves to the designated position.

[0059] When the first clamping block 16 touches the inner side of the X-axis frame 14, the third hydraulic cylinder 15 continues to retract, which can drive the second clamping block 18 to move, so that the second clamping block 18 moves closer to the first clamping block 16 with the first clamping block 16 as a reference, and clamps the X-axis frame 14.

[0060] When the L-shaped main body 11 moves, it can drive the push plate 27 to move, so that the push plate 27 moves to the corner of the two X and Y axis frame 14, and activates the second hydraulic cylinder 12 to retract. During the retraction of the second hydraulic cylinder 12, it can drive the push plate 27 to move. The movement of the push plate 27 can push the Y axis frame 14 to move outward, so that one side of the Y axis frame 14 is separated from the photovoltaic panel 13 and the Y axis frame 14.

[0061] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
