Description

Technical Field

[0001] The present invention specifically relates to a waste photovoltaic module frame separation device and its application, belonging to the technical field of cutting and transmission devices. Background Art

[0002] With the growing global demand for renewable energy, photovoltaic power generation has gained widespread adoption as a clean and sustainable form of energy. As the core component of a photovoltaic power generation system, the performance and lifespan of photovoltaic modules directly impact the overall system's power generation efficiency and economic benefits. Double-glass photovoltaic modules, due to their high photoelectric conversion efficiency and excellent mechanical properties, have gradually become the mainstream in the market. However, as photovoltaic modules age, a large number of retired modules urgently need to be disposed of. If discarded photovoltaic modules are not properly handled, they will have a serious impact on the environment. These modules contain hazardous substances such as lead, fluorine, and cadmium. If simply incinerated or buried, these substances may seep into the soil and water, endangering ecology and human health. Furthermore, these modules contain valuable resources such as silicon, silver, and copper. Failure to recycle them after disposal will lead to resource waste and exacerbate the exploitation of primary resources. Therefore, the cutting and disassembly of the double-glass aluminum frames of these retired photovoltaic modules is a critical step.

[0003] Photovoltaic glass generally adopts a rectangular design. The rectangle can be arranged efficiently, fully utilizes space, reduces gaps, improves power generation efficiency, and is easy to manufacture and install, facilitating mass production and rapid installation. It conforms to standardized module sizes and is easy to combine into large photovoltaic arrays. The rectangular structure has good mechanical strength and supporting performance. The long side of the rectangular panel can be installed along the wind direction to reduce the pressure of wind load on the bracket.

[0004] Patent document CN221439496U discloses a photovoltaic panel frame dismantling and recycling device, "including a conveying mechanism for conveying photovoltaic panels; a lifting and fixing mechanism, which is arranged above the conveying mechanism and is used to fix the photovoltaic panels; a dismantling mechanism, which is arranged above the conveying mechanism, and the dismantling mechanism includes a lifting platform, an electric cylinder arranged on the lifting platform, and a dismantling plate is provided on the telescopic rod of the electric cylinder, and an integrally formed extension plate is provided on the dismantling plate. The dismantling plate and the extension plate are L-shaped, and a cylinder is provided at the bottom of the extension plate; wherein, the photovoltaic panel frame is squeezed onto the dismantling plate by the cylinder, and the extension plate can be pressed on the photovoltaic panel frame, thereby preventing the frame from flipping over and damaging the photovoltaic panel during dismantling, and the conveying mechanism includes a first conveying assembly, a second conveying assembly and a third conveying assembly which are arranged in sequence at intervals. The extension plate of the present invention presses the photovoltaic panel frame, the cylinder extends, and the telescopic rod of the cylinder fixes the photovoltaic panel frame on the dismantling plate to prevent the frame from flipping over and damaging the photovoltaic panel during dismantling."

[0005] The present application discloses that after the discarded photovoltaic frames are dismantled, it is impossible to transport the dismantled frames, and human intervention is still required to remove the frames from the dismantling mechanism, which requires high manpower and has low dismantling efficiency. In order to solve this problem, we propose a cutting and transmission device specifically for the transmission and dismantling of photovoltaic double-glass aluminum frames. The device is designed to promote the regularization and large-scale processing of retired double-glass aluminum frames, improve production efficiency, and ensure the safety of workers.

When cutting the photovoltaic double-glass aluminum frame, after placing the photovoltaic glass on the first frame 1, the long side of the photovoltaic double-glass aluminum frame can be cut by cooperating with the first pressing component and the long side sawing component.

[0041] The long side sawing assembly includes two first sawing assemblies symmetrically arranged on the first frame 1, the first sawing assemblies corresponding one-to-one to the front ends of the long sides of the aluminum frame, and the first sawing assemblies are used to cut the corresponding long sides of the aluminum frame. The first sawing assembly includes a first circular saw 10 and a first motor 12 for driving the first circular saw 10. The first circular saws 10 are symmetrically arranged on the first frame 1, and the first circular saw 10 is used to cut the long sides of the aluminum frame. The first motor 12 is fixedly arranged on the first frame 1, and the output end of the first motor 12 is fixedly connected to the center position of the corresponding first circular saw 10;

[0042] A motor corresponding to the first circular saw 10 is provided on the first frame 1. The motor can drive the first circular saw 10 to rotate, thereby cutting the long side aluminum frame of the photovoltaic glass. During the cutting process, the first circular saw 10 is protected by a shielding cover to prevent dust from flying during sawing. The shielding cover is fixedly connected to the first frame 1 through a bracket. The first pressing assembly includes a plurality of pressing structures arranged along the transmission direction. The plurality of pressing structures are arranged at intervals along the transmission direction of the first transmission assembly.

[0043] The first pressing assembly includes a plurality of pressing structures arranged along the transmission direction, and the plurality of pressing structures are arranged at intervals along the transmission direction of the first transmission assembly. The pressing structure includes a frame 22, a first pressing roller 23 and a first transmission roller 9.

The frame 22 is also provided with a first lifting module 24 for driving the first pressing roller 23 to move up and down, and the telescopic end of the first lifting module 24 is fixedly connected to the first pressing roller 23

[0044] When the first transmission component moves to transport the photovoltaic glass, the position of the first pressing roller 23 will be adjusted through the operation of the first lifting module 24. After the first pressing roller 23 moves down and contacts the surface of the photovoltaic glass, the position of the photovoltaic glass will be limited, thereby facilitating the first circular saw 10 to cut the long side of the aluminum frame of the photovoltaic glass, and a pushing effect will be generated during sawing.

[0045] The second frame 13 is also provided with a material limiting assembly, which is used to limit the aluminum frame from being disassembled and scattered during the sawing process.

The telescopic end of the second lifting module 26 is fixedly connected to one end of the second nip roller 25.

[0046] The movement of the second lifting module 26 can adjust the position of the second pressing roller 25. When the second pressing roller 25 moves downward, it will apply pressure to the photovoltaic glass and the aluminum frame to prevent the aluminum frame from flying away. At the same time, the second pressing roller 25 can be replaced with a strip frame to fully limit and press the photovoltaic glass.

[0047] The short-side sawing assembly includes two second sawing assemblies symmetrically arranged on the second frame 13. The second sawing assemblies correspond one-to-one to the front ends of the short sides of the aluminum frame. The second sawing assemblies are used to cut the corresponding short sides of the aluminum frame. The second sawing assembly includes a second circular saw 16. The second circular saw 16 is symmetrically arranged on the second frame 13, and the second circular saw 16 is used to cut the short sides of the aluminum frame.

[0048] The second circular saw 16 is aligned with the short side of the aluminum frame. Once the photovoltaic glass moves and contacts the short side of the aluminum frame, it can cut the short side of the aluminum frame. During the cutting process, a shield protects the second circular saw 16 to prevent dust from flying around during sawing. The shield is fixedly connected to the second frame 13 via a bracket. The conveyor mechanism includes a third frame 27 and a conveyor belt 11 mounted thereon. The width of the third frame 27 is less than that of the first frame 1.

[0049] The photovoltaic glass with the cut long edges can be transferred to the second rack 13 via the conveyor belt 11 .

[0050] The second transmission assembly includes a push block 14, a third motor 19, a drive rod 20, and a chain 21. The push block 14 is symmetrically arranged on the second frame 13. The third motor 19 is fixedly mounted on the second frame 13. The drive rod 20 is rotatably mounted on the second frame 13. The chain 21 is mounted on the drive rod 20 via a sprocket. The chain 21 is fixedly connected to the corresponding push block 14. The third motor 19 is in transmission connection with the drive rod 20.

[0051] The operation of the No. 3 motor 19 will drive the driving rod 20 to rotate. A sprocket corresponding to the chain 21 is provided on the first frame 1. When the driving rod 20 rotates, the chain 21 will rotate through the cooperation of the sprocket. The rotation of the chain 21 will drive the pushing block 14 to move. The movement of the pushing block 14 can push the retired photovoltaic double-glass panel to move for short-side cutting.

[0052] The first transmission assembly includes a mounting frame 3, an electric push rod 4, a support frame 5, a No. 1 conveyor belt 6 and a No. 1 motor 7. The No. 1 conveyor belt 6 is rotatably arranged on the support frame 5 by a gear. The No. 1 motor 7 is fixedly mounted on the support frame 5, and the gear mounted on the output end of the No. 1 motor 7 is meshed with the gear for mounting the No. 1 conveyor belt 6. The mounting frame 3 is fixedly mounted on the first frame 1, the electric push rod 4 is fixedly mounted on the mounting frame 3, and the support frame 5 is fixedly connected to one end of the electric push rod 4;

[0053] After the No. 1 conveyor belt 6 contacts the edge of the retired photovoltaic double-glass panel, the No. 1 motor 7 will drive the No. 1 conveyor belt 6 to rotate. The rotation of the No. 1 conveyor belt 6 will move the retired photovoltaic double-glass panel, which facilitates the movement of the retired photovoltaic double-glass panel. The No. 2 conveyor belt 8 is used to limit the edge of the retired photovoltaic double-glass panel and assist in the movement of the retired photovoltaic double-glass panel.

[0054] A No. 2 conveyor belt 8 is installed on the first frame 1 through gears, and the No. 2 conveyor belt 8 is symmetrically arranged with the No. 1 conveyor belt 6. The length of the first pressing roller 23 is less than the width of the photovoltaic glass, so as to limit the conveyed photovoltaic glass. A No. 4 frame 28 is provided on the side of the second frame 13. The No. 4 frame 28 is provided with a rear conveyor belt 17 for unloading the cut photovoltaic glass. The width of the No. 4 frame 28 is less than the width of the second frame 13. An inclined chip removal channel 29 is provided on the second frame 13, and the chip removal channel 29 is located on the side corresponding to the second circular saw 16;

[0055] After the cut photovoltaic glass moves to the rear conveyor belt 17, the photovoltaic glass can be unloaded through the rear conveyor belt 17. At the same time, the width of the fourth frame 28 is smaller than the width of the second frame 13. The cut aluminum frame will fall directly to the ground. When the second circular saw 16 cuts the aluminum frame, the generated debris will fall into the chip discharge channel 29, and the debris and impurities will be collected and discharged through the chip discharge channel 29.

[0056] Compared with the existing design, the long side cutting mechanism and the short side cutting mechanism are set separately, and the aluminum frame after the long side cutting is completed is transferred to the short side cutting mechanism through the transmission mechanism, making the cutting process clearer, more orderly, and easier to operate and maintain. Each mechanism can focus on a specific cutting task, which improves the accuracy and efficiency of cutting. The long side sawing assembly includes two first sawing assemblies symmetrically arranged on the first frame 1, which can cut the two long sides of the aluminum frame at the same time, greatly improving the cutting efficiency. Moreover, since the two circular saws are symmetrically arranged, the force is evenly distributed during the cutting process, which helps to ensure the consistency of the cutting quality and reduce cutting errors. The short side sawing assembly includes two second sawing assemblies symmetrically arranged on the second frame 13, which also achieves the simultaneous cutting of the two short sides of the aluminum frame, further improving the overall cutting efficiency. Furthermore, the force on the aluminum frame is balanced during cutting, which is beneficial to ensuring the accuracy and stability of the short side cutting. The first pressing assembly includes multiple pressing structures arranged along the transmission direction. The multiple pressing structures are arranged at intervals along the transmission direction of the first transmission assembly. During the transmission of the photovoltaic glass, the photovoltaic glass can be pressed and limited at any time as needed to ensure the stability of the photovoltaic glass position during the long side sawing process and avoid affecting the cutting accuracy due to the movement of the photovoltaic glass. At the same time, the first lifting module 24 can drive the first pressing roller 23 to move up and down, making it convenient to adjust the pressing force according to the different specifications of photovoltaic glass, thereby improving the versatility and adaptability of the device. The second frame 13 is provided with an inclined chip removal channel 29, and the chip removal channel 29 is located on the side corresponding to the second circular saw 16. When the second circular saw 16 cuts the aluminum frame, the generated debris will fall into the chip removal channel 29. The debris and impurities will be collected and discharged through the chip removal channel 29, keeping the working environment clean and tidy, reducing the impact of debris on the cutting process and equipment, and facilitating the centralized processing of debris.

[0057] Example 2

[0058] The second frame 13 is further provided with a second pressing assembly, which includes a second pressing roller 25 and a second transmission roller 30. The second pressing roller 25 is fixedly connected to the second lifting module 26. The second transmission roller 30 and the second pressing roller 25 are spaced apart in the vertical direction.

[0059] After cutting the long side of the aluminum frame of the photovoltaic glass, the photovoltaic glass is transferred to the second frame 13 for cutting the short side. The second lifting module 26 is moved to adjust the position of the limit frame 18. When the limit frame 18 moves down, it will apply pressure to limit the photovoltaic glass and the aluminum frame to prevent the aluminum frame from flying around. The photovoltaic glass is fully limited and pressed. After cutting the aluminum frame, the width of the fourth frame 28 is smaller than the width of the second frame 13, and the cut aluminum frame will fall directly to the ground, making it easier for the cut aluminum frame to fall directly to the ground.

[0060] As a technical optimization solution of the present invention, first, when cutting the photovoltaic double-glass aluminum frame using a cutting and transmission device for the photovoltaic double-glass aluminum frame, when cutting the photovoltaic double-glass aluminum frame, after placing the photovoltaic glass on the first frame 1, the long side of the photovoltaic double-glass aluminum frame can be cut by cooperating with the first pressing component and the long side sawing component, and then the photovoltaic glass with the cut long side is transferred to the second frame 13 by the conveyor belt 11, and the short side of the photovoltaic glass can be cut by cooperating with the second transmission component and the short side sawing component. The width of the fourth frame 28 is smaller than the width of the second frame 13. The second transmission component moves to transport the photovoltaic glass and the cut aluminum frame, and the aluminum frame will fall directly to the ground. After the cut photovoltaic glass moves to the rear conveyor belt 17, the photovoltaic glass can be unloaded through the rear conveyor belt 17. At the same time, the width of the fourth frame 28 is smaller than the width of the second frame 13, and the cut aluminum frame will fall directly to the ground. When the second circular saw 16 cuts the aluminum frame, the debris generated will fall into the chip discharge channel 29, and the debris and impurities will be collected and discharged through the chip discharge channel 29, so as to facilitate the cutting of the photovoltaic double-glass aluminum frame and improve work efficiency.

[0061] Compared with the existing design, when the long side of the photovoltaic glass aluminum frame is cut and then transferred to the second frame 13 for short side cutting, the position of the limit frame 18 is adjusted by the second lifting module 26, and the limit frame 18 moves down to fully pressure and limit the photovoltaic glass and the aluminum frame, which can effectively prevent the aluminum frame from flying during the cutting process, ensure the safety of the operator, and at the same time ensure the stability of the cutting process, and improve the quality of short side cutting. The width of the fourth frame 28 is smaller than the width of the second frame 13. When the second transmission component moves to transport the photovoltaic glass and the cut aluminum frame, the aluminum frame will fall directly to the ground. After the cut photovoltaic glass moves to the rear conveyor belt 17, it is unloaded by the rear conveyor belt 17, realizing the classification processing of the aluminum frame and the photovoltaic glass, facilitating the subsequent collection and further processing of the aluminum frame and the photovoltaic glass, and improving the convenience and efficiency of production management.

[0062] Example 3

[0063] The first conveyor belt 9 drives the aluminum frame 2 to move along the first frame 1 and the second conveyor belt 8 drives the aluminum frame 2 to move along the first frame 1. The aluminum frame 2 is sent to the conveyor belt 11. Since there is a gap on both sides between the third frame 27 and the first frame 1, the width of the conveyor belt 11 is smaller than the length of the short side of the aluminum frame 2. The long side of the cut aluminum frame 2 falls directly to the ground through the gap between the two sides of the conveyor belt 11 and the third frame 27. The aluminum frame 2 is transmitted to the second frame 13 through the conveyor belt 11. The pushing block 14 in the second transmission assembly pushes the aluminum frame 2 to move horizontally toward the second pressing roller 25. The second pressing roller 25 and the limit frame 18 are pressed on the second lifting module 26. On the aluminum frame 2, the photovoltaic glass is fully limited and pressed, and the short side of the aluminum frame 2 is sawed by the second circular saw 16 in the short side sawing assembly, and the raw debris will fall into the chip discharge channel 29. The debris and impurities will be collected and discharged through the chip discharge channel 29. After the cut photovoltaic glass is moved to the rear conveyor belt 17, the photovoltaic glass can be unloaded through the rear conveyor belt 17. There is a gap between the rear conveyor belt 17 and the No. 4 frame 28 on both sides. The short side of the cut aluminum frame 2 will fall directly to the ground.

[0064] Compared with the existing design, the electric push rod 4 drives the No. 1 conveyor belt 6 to move in the direction of the aluminum frame 2, so that it cooperates with the No. 2 conveyor belt 8 to contact and clamp the two sides of the aluminum frame 2, thereby achieving precise limiting of the aluminum frame 2, effectively preventing the aluminum frame 2 from shifting during the longitudinal transmission process, ensuring that the aluminum frame 2 is accurately positioned during subsequent long side sawing, thereby improving the accuracy of long side cutting, the cut aluminum frame 2 is conveyed to the conveyor belt 11, and since there is a gap on both sides between the third frame 27 and the first frame 1, and the width of the conveyor belt 11 is smaller than the length of the short side of the aluminum frame 2, the long side of the cut aluminum frame 2 falls directly to the ground through the gap between the two sides of the conveyor belt 11 and the third frame 27, which facilitates the collection of the long side of the cut aluminum frame and avoids accumulation on the equipment affecting subsequent operations; on the other hand, the space is reasonably utilized to make the equipment structure more compact. During the long side sawing process, the first lifting module 24 drives the first pressing roller 23 to move downward for pressing, and the first pressing roller 23 is located between the long sides of the aluminum frames 2 on both sides of the photovoltaic glass. This design can stably press the aluminum frame 2 and the photovoltaic glass during cutting, reduce vibration and displacement during the cutting process, and further improve the quality of long side cutting. After the aluminum frame 2 is transmitted to the second frame 13 through the conveyor belt 11, the push block 14 in the second transmission component pushes the aluminum frame 2 to move laterally toward the second pressing roller 25. The second pressing roller 25 and the limit frame 18 are pressed on the aluminum frame 2 through the second lifting module 26, and the photovoltaic glass is fully limited and pressed, which can ensure that the aluminum frame 2 moves laterally. The position during the sawing process is accurate, and when sawing the short side, the second pressing roller 25 and the limiting frame 18 are fully limited and pressed to ensure the stability of the short side cutting and reduce cutting errors. When the second circular saw 16 in the short side sawing assembly saws the short side of the aluminum frame 2, the generated debris will fall into the chip discharge channel 29. The second circular saw 16 is protected by a shielding cover to prevent dust from flying during sawing. The shielding cover is fixedly connected to the second frame 13 through a bracket, and the debris and impurities are collected and discharged through the chip discharge channel 29. The debris generated during the cutting process can be cleaned in time, the working environment can be kept clean, the impact of the debris on the equipment and operators can be reduced, and the centralized processing of the debris is also convenient.

[0065] Example 4

[0066] A cutting and transmission method for photovoltaic double-glass aluminum frames. Compared with Example 3, in this embodiment, the cut aluminum frame 2 is placed on the first frame 1 and the aluminum frame 2 is longitudinally transmitted by the first transmission component. During the process of sawing the long side of the aluminum frame 2 by the long side sawing component, the sawing depth of the first circular saw 10 is controlled at both ends of the long side of the aluminum frame 2 to ensure that the long side of the aluminum frame 2 is adhered to the side close to the short side. When the aluminum frame 2 is transported by the conveyor belt 11, the long side is driven to move synchronously. When the short side sawing component saws the short side, the adhesion with the long side is cut synchronously. In the process of cutting, the adhesion part of the long side and the short side is cut first to avoid directly cutting the short side and causing warping.

[0067] Compared to existing designs, by controlling the cutting depth of the first circular saw 10 at both ends of the long side of the aluminum frame 2, the long side of the aluminum frame 2 closest to the short side is ensured to adhere to the short side. This allows the aluminum frame 2 to move synchronously with the long side as it is transported by the conveyor belt 11, allowing the short side sawing assembly to simultaneously cut away the adhesion to the long side. By first cutting away the adhesion between the long and short sides, the warping caused by cutting directly onto the short side is effectively avoided, ensuring the flatness of the aluminum frame after cutting and improving cutting quality.
