Description

Technical Field

[0001] This invention relates to the field of photovoltaic module recycling, and more specifically, to a photovoltaic recycling system. Background Technology

[0002] Photovoltaic modules are widely used in various fields. During use, they gradually age due to environmental corrosion, ultraviolet radiation, and other factors, leading to a decline in battery efficiency and eventual disposal. Waste photovoltaic modules contain a large number of recyclable components such as tempered glass, crystalline silicon, copper, and aluminum. Therefore, proper disposal of waste photovoltaic modules is crucial to avoiding resource waste and reducing environmental pollution.

[0003] In related technologies, photovoltaic module recycling relies on manual recycling, which is costly and inefficient. Summary of the Invention

[0004] The present invention aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, embodiments of the present invention propose a photovoltaic recycling system with high recycling efficiency and low recycling cost.

[0006] A photovoltaic recycling system according to an embodiment of the present invention includes: a frame and a transport assembly, the transport assembly being disposed on the frame and used for transporting photovoltaic panels; a first cutting assembly, the first cutting assembly being disposed on the frame and located above the transport assembly, the first cutting assembly being movable horizontally relative to the frame, the first cutting assembly being used for cutting fasteners of the photovoltaic panels; and a frame disassembly assembly, the frame disassembly assembly including a clamping member and a disassembly member, the clamping member and the disassembly member being both disposed on the frame and both located downstream of the first cutting assembly, the clamping member being used for clamping the photovoltaic panels to fix the photovoltaic panels, the disassembly member being adapted to abut against the inner circumferential surface of the frame of the photovoltaic panels, the disassembly member being movable relative to the frame from inside the frame toward outside the frame, so that the disassembly member disassembles the frame of the photovoltaic panels.

[0007] The photovoltaic recycling system of this invention includes a frame, a transport component, a first cutting component, and a frame disassembly component. The transport component transports the photovoltaic panels, eliminating the need for manual handling and ensuring the continuity of each disassembly process, reducing reliance on manpower. The first cutting component cuts the fasteners of the photovoltaic panels, replacing manual disassembly, which improves cutting efficiency and ensures the separation effect between the frame and the backsheet, laying the foundation for subsequent processes. This achieves efficient and stable frame disassembly, avoiding the inefficiency of manual operation. Furthermore, the frame disassembly component disassembles the photovoltaic panel frame, eliminating the need for direct manual intervention in the core stripping and disassembly operations. This avoids the safety risk of workers being scratched by the cover glass, reduces the risk of work interruption, and ensures disassembly quality through mechanized operation, preventing the loss of recyclable components due to human error, thus improving the disassembly efficiency of photovoltaic panels.

[0008] In some embodiments, the first cutting assembly includes a mounting frame, a first cutting element, and a second cutting element. The mounting frame is mounted on the frame, and both the first and second cutting elements are mounted on the frame. Both the first and second cutting elements are movable relative to the frame in the vertical direction and in the width direction of the frame, so that the first and second cutting elements can cut the fasteners of the photovoltaic panel.

[0009] In some embodiments, the photovoltaic recycling system further includes a positioning component disposed on the frame and located between the first cutting component and the transport component. The positioning component has a first state and a second state. In the first state, the positioning component abuts against the photovoltaic panel to position the photovoltaic panel so that the first cutting component cuts the fasteners of the photovoltaic panel. In the second state, the positioning component separates from the photovoltaic panel so that the transport component transports the photovoltaic panel.

[0010] In some embodiments, the positioning component includes a first positioning member and a second positioning member. Both the first and second positioning members are disposed on the frame and spaced apart along the length of the frame. Both the first and second positioning members are movable relative to the frame in a vertical direction. In a first state, the first positioning member abuts against the front end of the photovoltaic panel, and the fastener at the front end of the photovoltaic panel is located below the first cutting component, so that the first cutting component cuts the fastener at the front end of the photovoltaic panel. In a second state, the second positioning member abuts against the rear edge of the photovoltaic panel, and the fastener at the rear end of the photovoltaic panel is located below the first cutting component, so that the first cutting component cuts the fastener at the rear end of the photovoltaic panel.

[0011] In some embodiments, the transport assembly includes a first transport member and a second transport member. The first transport member is a roller conveyor disposed on the frame and located below the first cutting assembly. The second transport member is a chain conveyor disposed on the frame and located below the frame removal assembly. The second transport member is movable relative to the frame in a vertical direction between a first position and a second position. In the first position, the second transport member is located on the frame to transport the photovoltaic panel. In the second position, the second transport member is located within the frame.

[0012] In some embodiments, the clamping member includes a first clamping plate and a second clamping plate. The first clamping plate and the second clamping plate are both disposed on the frame and are spaced apart from each other in the vertical direction. The first clamping plate is located below the second transport member, and the second clamping plate is located above the second transport member. The second clamping plate is movable in the vertical direction relative to the frame, so that when the photovoltaic panel is transported above the first clamping plate, the second transport member is in a second position, the photovoltaic panel is placed on the first clamping plate, and the second clamping plate moves downward to clamp the photovoltaic panel.

[0013] In some embodiments, the disassembly components include: a first disassembly plate and a second disassembly plate, the first and second disassembly plates being spaced apart on the frame along the width direction of the frame, the first and second disassembly plates moving relative to or away from the width direction of the frame, the first and second disassembly plates being located within the frame of the photovoltaic panel and abutting against the inner peripheral surface of the frame, so that the first and second disassembly plates disassemble the frame; a third disassembly plate and a fourth disassembly plate, the third and fourth disassembly plates being spaced apart on the frame along the length direction of the frame, the third and fourth disassembly plates moving relative to or away from the length direction of the frame, the third and fourth disassembly plates being located within the frame of the photovoltaic panel and abutting against the inner peripheral surface of the frame, so that the third and fourth disassembly plates disassemble the frame.

[0014] In some embodiments, the photovoltaic recycling system further includes a backsheet disassembly assembly located downstream of the frame disassembly assembly. The backsheet disassembly assembly includes a second cutting assembly, a backsheet peeling assembly, and a crystalline silicon collection assembly. The second cutting assembly, the backsheet peeling assembly, and the crystalline silicon collection assembly are all mounted on the frame. The second cutting assembly is used to cut the backsheet of the photovoltaic panel. The backsheet peeling assembly is used to peel the cut backsheet from the photovoltaic panel. The crystalline silicon collection assembly is used to collect the crystalline silicon on the peeled photovoltaic panel.

[0015] In some embodiments, the photovoltaic recycling system further includes a backsheet collection assembly, which is located downstream of and spaced apart from the backsheet disassembly assembly. The backsheet collection assembly includes a collection box and a third transport component, which is located above the transport assembly and has a transport direction opposite to that of the transport assembly. The backsheet stripping assembly transports the stripped backsheet onto the third transport component. The collection box is located between the backsheet collection assembly and the third transport component so that the backsheet on the third transport component can be transported into the collection box.

[0016] In some embodiments, the photovoltaic recycling system further includes a junction box disassembly assembly, which includes a mounting frame and a disassembly hand. The mounting frame is mounted on the frame and located on the side of the first cutting assembly away from the frame disassembly assembly. The disassembly hand is mounted on the mounting frame and is movable along the length of the mounting frame. The disassembly hand moves vertically relative to the mounting frame so that it can grasp the junction box on the photovoltaic panel to disassemble the junction box. Attached Figure Description

[0024] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0025] A photovoltaic recycling system 100 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0026] like Figures 1-6 As shown, the photovoltaic recycling system 100 according to an embodiment of the present invention includes a frame 1, a transport component 2, a first cutting component 3, and a frame disassembly component 4.

[0027] Transport component 2 is mounted on rack 1 and is used to transport photovoltaic panels. Specifically, as shown... Figures 1-3 As shown, the frame 1 has a frame structure that extends in the front-to-back direction. The transport component 2 is set on the frame 1, and the photovoltaic panels can be placed on the transport component 2. The transport component 2 can realize the transportation of the photovoltaic panels.

[0028] The first cutting assembly 3 is mounted on the frame 1 and located above the transport assembly 2. The first cutting assembly 3 moves horizontally relative to the frame 1 and is used to cut the fasteners of the photovoltaic panel. Specifically, as shown... Figures 1-4 As shown, the photovoltaic panel is rectangular in shape, and its structure includes a glass panel, crystalline silicon, a backsheet, a frame, and a junction box. The glass panel, crystalline silicon, and backsheet are all located inside the frame and connected to it via fasteners. The junction box is mounted on the backsheet. A first cutting assembly 3 is mounted on the frame 1 and can move left and right on the frame 1. The first cutting assembly 3 is used to cut the fasteners on the photovoltaic panel, thereby disassembling the fasteners.

[0029] The frame removal assembly 4 includes a clamping member 41 and a removal member 42. Both the clamping member 41 and the removal member 42 are mounted on the frame 1 and are located downstream of the first cutting assembly 3. The clamping member 41 clamps the photovoltaic panel to secure it. The removal member 42 is adapted to abut against the inner circumferential surface of the photovoltaic panel's frame. The removal member 42 moves relative to the frame 1 from inside the frame 1 toward outside the frame 1 to remove the photovoltaic panel's frame. Specifically, as... Figures 1-6 As shown, the clamping member 41 is mounted on the frame 1 and located behind the first cutting assembly 3. After the first cutting assembly 3 completes the cutting operation, the transport assembly 2 transports the photovoltaic panel to the position of the clamping member 41, which then clamps and secures the photovoltaic panel. The disassembly member 42 is also mounted on the frame 1 and can move from the inside to the outside of the frame 1. After the photovoltaic panel is secured, the disassembly member 42 abuts against the inner circumferential surface of the photovoltaic panel frame, thereby removing the frame from the photovoltaic panel.

[0030] The photovoltaic recycling system 100 of this invention includes a transport component 2, a first cutting component 3, and a frame disassembly component 4. The transport component 2 transports the photovoltaic panels, eliminating the need for manual handling and ensuring the continuity of each disassembly process, thus reducing reliance on manpower. Furthermore, the first cutting component 3 cuts the fasteners of the photovoltaic panels, replacing manual disassembly, improving cutting efficiency and ensuring effective separation of the frame from the backsheet, laying the foundation for subsequent processes. This achieves efficient and stable frame disassembly, avoiding the inefficiency of manual operation. Finally, the frame disassembly component 4 disassembles the photovoltaic panel frame. The entire disassembly process requires no direct manual intervention in core stripping and disassembly operations, avoiding the safety risk of workers being scratched by the cover glass, reducing the risk of work interruption, and ensuring disassembly quality through mechanized operation. This prevents the loss of recyclable components due to human error, improving the disassembly efficiency of the photovoltaic panels.

[0031] In some embodiments, the first cutting assembly 3 includes a mounting frame 31, a first cutting element 32, and a second cutting element 33. The mounting frame 31 is disposed on the frame 1, and both the first cutting element 32 and the second cutting element 33 are disposed on the frame 1. Both the first cutting element 32 and the second cutting element 33 are movable relative to the frame 1 in the vertical direction and in the width direction of the frame 1, so that the first cutting element 32 and the second cutting element 33 can cut the fasteners of the photovoltaic panel.

[0032] Specifically, such as Figure 2 and Figure 4 As shown, the mounting frame 31 is a frame extending in the left-right direction and fixed on the machine frame 1. The first cutting component 32 and the second cutting component 33 are both mounted on the machine frame 1 and can move in the left-right direction on the machine frame 1. The mounting frame 31 is provided with a linear slide rail extending in the left-right direction. The first cutting component 32 and the second cutting component 33 each include a first mounting seat, a second mounting seat, a telescopic rod, a cutter head, and a motor. The first mounting seat is mounted on the mounting frame 31 and cooperates with the linear slide rail. It is driven by a drive component to move on the linear slide rail, so that the first mounting seat moves in the extension direction of the linear slide rail. The telescopic component can be a cylinder and is mounted on the first mounting seat. The second mounting seat is located below the first mounting seat and is connected to the telescopic component. Thus, the telescopic component moves in the up-down direction to drive the second mounting seat to move in the up-down direction. The cutter head is mounted on the second mounting seat and can rotate on the second mounting seat. The motor is mounted on the second mounting seat and is connected to the cutter head, so that the motor drives the cutter head to rotate to cut the fasteners and realize the disassembly of the photovoltaic panel fasteners.

[0033] In some embodiments, the photovoltaic recycling system 100 further includes a positioning component 5, which is disposed on the frame 1 and located between the first cutting component 3 and the transport component 2. The positioning component 5 has a first state and a second state. In the first state, the positioning component 5 abuts against the photovoltaic panel to position the photovoltaic panel so that the first cutting component 3 can cut the fasteners of the photovoltaic panel. In the second state, the positioning component 5 is separated from the photovoltaic panel so that the transport component 2 can transport the photovoltaic panel. Specifically, as Figure 2 As shown, the positioning component 5 is mounted on the frame 1 and located between the first cutting component 3 and the transport component 2. When the fasteners of the photovoltaic panel need to be cut, the positioning component 5 extends above the frame 1 and abuts against the photovoltaic panel, restricting the displacement of the photovoltaic panel on the transport component 2. This ensures that the fasteners of the photovoltaic panel are aligned with the cutter head of the first cutting component 3, providing a reliable positioning basis for the precise cutting of the first cutting component 3. When the positioning component 5 is in the second state, it is located inside the frame 1 and completely separated from the photovoltaic panel, releasing the limiting constraint on the photovoltaic panel so that the transport component 2 can drive the photovoltaic panel to continue to be transported to the subsequent disassembly station.

[0034] In some embodiments, the positioning component 5 includes a first positioning element 51 and a second positioning element 52, both of which are disposed on the frame 1 and along the length direction of the frame 1 (e.g., ...). Figure 1 As shown in the front-to-back direction, the first positioning member 51 and the second positioning member 52 are spaced apart. Both are movable in the vertical direction relative to the frame 1. In the first state, the first positioning member 51 abuts against the front end of the photovoltaic panel, and the fastener at the front end of the photovoltaic panel is located below the first cutting assembly 3, so that the first cutting assembly 3 can cut the fastener at the front end of the photovoltaic panel. In the second state, the second positioning member 52 abuts against the rear edge of the photovoltaic panel, and the fastener at the rear end of the photovoltaic panel is located below the first cutting assembly 3, so that the first cutting assembly 3 can cut the fastener at the rear end of the photovoltaic panel. Specifically, as shown in the figure... Figure 4 As shown, both the first positioning component 51 and the second positioning component 52 are mounted on the frame 1, with the first positioning component 51 positioned behind the second positioning component 52. The first positioning component 51 includes a first cylinder and a first positioning plate. The first cylinder is fixedly mounted on the frame 1 and connected to the first positioning plate, thereby driving the first positioning plate to move in the up-down direction. The second positioning component 52 includes a second cylinder and a second positioning plate. The second cylinder is fixedly mounted on the frame 1 and connected to the second positioning plate, thereby driving the second positioning plate to move in the up-down direction.

[0035] When it is necessary to cut the fasteners at the front end of the photovoltaic panel, the first cylinder extends so that the front side of the first positioning plate abuts against the rear side of the photovoltaic panel, thereby positioning the photovoltaic panel. At the same time, the first cutting piece 32 and the second cutting piece 33 are both located above the fasteners at the front end of the photovoltaic panel, so that the first cutting piece 32 and the second cutting piece 33 cut the fasteners at the front end of the photovoltaic panel.

[0036] When it is necessary to cut the fasteners at the rear end of the photovoltaic panel, the second cylinder extends so that the front side of the second positioning plate abuts against the rear side of the photovoltaic panel frame, thereby positioning the photovoltaic panel by the first positioning plate. At the same time, the first cutting piece 32 and the second cutting piece 33 are both located above the fasteners at the rear end of the photovoltaic panel, thereby cutting the fasteners at the rear end of the photovoltaic panel by the first cutting piece 32 and the second cutting piece 33.

[0037] In some embodiments, the transport assembly 2 includes a first transport member 21 and a second transport member 22. The first transport member 21 is a roller conveyor and is disposed on the frame 1, located below the first cutting assembly 3. The second transport member 22 is a chain conveyor and is disposed on the frame 1, located below the frame removal assembly 4. The second transport member 22 is movable relative to the frame 1 in a vertical direction between a first position and a second position. In the first position, the second transport member 22 is located on the frame 1 to transport photovoltaic panels. In the second position, the second transport member 22 is located within the frame 1. Specifically, as... Figure 1 As shown, the first transport component 21 and the second transport component 22 are both mounted on the frame 1 and spaced apart in the front-to-back direction. The first transport component 21 can be a roller conveyor and is located below the first cutting assembly 3, thereby transporting the photovoltaic panel through the first transport component 21.

[0038] The second transport component 22 can be a chain conveyor and moves vertically between a first position and a second position on the frame 1. In the first position, the second transport component 22 is located above the frame 1, so that the second transport component 22 transports the photovoltaic panel. In the second position, the second transport component 22 is located inside the frame 1, so that the photovoltaic panel is placed on the clamping component 41, thereby clamping the photovoltaic panel by the feeding component.

[0039] It is worth noting that the second transport component 22 can be moved in the vertical direction in the first and second positions by a lifting drive mechanism (such as a lifting cylinder, screw jack, etc.). The lifting drive mechanism is set on the frame 1, and the extension and retraction movement of the lifting drive mechanism drives the entire chain conveyor to move in the vertical direction.

[0040] In some embodiments, the clamping member 41 includes a first clamping plate and a second clamping plate. Both the first and second clamping plates are disposed on the frame 1 and are spaced apart from each other in the vertical direction. The first clamping plate is located below the second transport member 22, and the second clamping plate is located above the second transport member 22 and is movable vertically relative to the frame 1. This allows the second transport member 22 to be in a second position when the photovoltaic panel is transported above the first clamping plate, with the photovoltaic panel placed on the first clamping plate, and the second clamping plate moving downwards to clamp the photovoltaic panel. Specifically, as shown... Figure 1 and Figure 5 As shown, both the first clamping plate and the second clamping plate are horizontal plates. The first clamping plate is fixed on the frame 1 and located below the second transport member 22. The second clamping plate is located on the frame 1 and above the second transport member 22. The second clamping plate and the first clamping plate are arranged opposite each other with vertical spacing. The second clamping plate is installed on the frame 1 by a cylinder. The cylinder's extension and retraction movement drives the second clamping plate to move in the vertical direction. When the second transport member 22 moves downward to the second position, the second transport member 22 is located below the first clamping plate, so that the photovoltaic panel is placed on the first clamping plate. The second clamping plate moves downward to clamp the photovoltaic panel.

[0041] In some embodiments, the disassembly member 42 includes a first disassembly plate 421, a second disassembly plate 422, a third disassembly plate 423, and a fourth disassembly plate 424.

[0042] The first disassembly plate 421 and the second disassembly plate 422 are along the width direction of the frame 1 (e.g., Figure 1 As shown in the left-right direction, the first disassembly plate 421 and the second disassembly plate 422 are spaced apart on the frame 1. The first disassembly plate 421 and the second disassembly plate 422 move relative to or away from each other in the width direction of the frame 1. The first disassembly plate 421 and the second disassembly plate 422 are located within the frame of the photovoltaic panel and abut against the inner circumferential surface of the frame, so that the first disassembly plate 421 and the second disassembly plate 422 can disassemble the frame. Specifically, as shown... Figure 5 and Figure 6 As shown, the first disassembly plate 421 and the second disassembly plate 422 are both vertical plates extending in the front-to-back direction. The first disassembly plate 421 and the second disassembly plate 422 are arranged opposite each other in the left-to-right direction on the frame 1. The cylinder connected to the second clamping plate is located between the first disassembly plate 421 and the second disassembly plate 422. The first disassembly plate 421 and the second disassembly plate 422 move relative to each other or away from each other in the left-to-right direction within the frame 1. When the clamping member 41 clamps the photovoltaic panel, the first disassembly plate 421 and the second disassembly plate 422 move away from each other in the left-to-right direction, so that the first disassembly plate 421 and the second disassembly plate 422 move away from each other. The first disassembly plate 421 can abut against the inner circumferential surface of the left frame of the photovoltaic panel, and the second disassembly plate 422 can abut against the inner circumferential surface of the right frame, thereby disassembling the left and right frames of the photovoltaic panel.

[0043] The third disassembly plate 423 and the fourth disassembly plate 424 are spaced apart on the frame 1 along its length. The third disassembly plate 423 and the fourth disassembly plate 424 move relative to or away from the frame 1 along its length. The third disassembly plate 423 and the fourth disassembly plate 424 are located within the frame of the photovoltaic panel and abut against the inner circumferential surface of the frame, so that the third disassembly plate 423 and the fourth disassembly plate 424 can disassemble the frame. Specifically, as shown... Figure 5 and Figure 6 As shown, the third disassembly plate 423 and the fourth disassembly plate 424 are both vertical plates extending in the left-right direction. The third disassembly plate 423 and the fourth disassembly plate 424 are arranged opposite each other in the front-back direction on the frame 1. The third disassembly plate 423 and the fourth disassembly plate 424 move towards each other or away from each other in the front-back direction within the frame 1. After the clamping member 41 clamps the photovoltaic panel, the third disassembly plate 423 and the fourth disassembly plate 424 move away from each other in the front-back direction, so that the third disassembly plate 423 and the fourth disassembly plate 424 move away from each other. The third disassembly plate 423 can abut against the inner peripheral surface of the front frame of the photovoltaic panel, and the fourth disassembly plate 424 can abut against the inner peripheral surface of the rear frame, thereby disassembling the front and rear frames of the photovoltaic panel.

[0044] In some embodiments, the disassembly component 42 further includes a first mounting plate, a second mounting plate, a first hydraulic rod, and a second hydraulic rod.

[0045] The first mounting plate and the second mounting plate are both mounted on the frame 1 and are spaced apart along the width of the frame 1. The first disassembly plate 421 and the second disassembly plate 422 are both located between the first mounting plate and the second mounting plate. Specifically, as shown... Figure 5 and Figure 6 As shown, the first mounting plate and the second mounting plate are both vertical plates extending in the front-to-back direction and fixed on the frame 1. The first mounting plate and the second mounting plate are arranged opposite each other in the left-to-right direction. The first disassembly plate 421 and the second disassembly plate 422 are located between the first mounting plate and the second mounting plate.

[0046] A first hydraulic rod is mounted on a first mounting plate and connected to a first disassembly plate 421, so that the first hydraulic rod drives the first disassembly plate 421 to move. A second hydraulic rod is mounted on a second mounting plate and connected to a second disassembly plate 422, so that the second hydraulic rod drives the second disassembly plate 422 to move. Specifically, as shown... Figure 5 and Figure 6 As shown, the base of the first hydraulic rod is fixed to the first mounting plate, and the piston rod of the first hydraulic rod is connected to the first disassembly plate 421. Thus, the first disassembly plate 421 is moved in the front-back direction by the extension and retraction of the first hydraulic rod. The base of the second hydraulic rod is fixed to the second mounting plate, and the piston rod of the second hydraulic rod is connected to the second disassembly plate 422. Thus, the second disassembly plate 422 is moved in the front-back direction by the extension and retraction of the second hydraulic rod.

[0047] In some embodiments, the disassembly component 42 further includes a third mounting plate, a fourth mounting plate, a third hydraulic rod, and a fourth hydraulic rod.

[0048] The third mounting plate and the fourth mounting plate are both mounted on the frame 1 and are spaced apart along the length of the frame 1. The third disassembly plate 423 and the fourth disassembly plate 424 are both located between the third mounting plate and the fourth mounting plate. Specifically, as shown in the figure... Figure 5 and Figure 6 As shown, the third mounting plate and the fourth mounting plate are both vertical plates extending in the left and right direction and fixed on the frame 1. The third mounting plate and the fourth mounting plate are arranged opposite each other in the front and back direction. The third disassembly plate 423 and the fourth disassembly plate 424 are located between the third mounting plate and the fourth mounting plate.

[0049] The third hydraulic rod is mounted on the third mounting plate and connected to the third disassembly plate 423, so that the third hydraulic rod drives the third disassembly plate 423 to move. The fourth hydraulic rod is mounted on the fourth mounting plate and connected to the fourth disassembly plate 424, so that the fourth hydraulic rod drives the fourth disassembly plate 424 to move. Specifically, as shown... Figure 5 and Figure 6 As shown, the base of the third hydraulic rod is fixed on the third mounting plate, and the piston rod of the third hydraulic rod is connected to the third disassembly plate 423. Thus, the third disassembly plate 423 is moved in the left and right direction by the extension and retraction of the third hydraulic rod. The base of the fourth hydraulic rod is fixed on the fourth mounting plate, and the piston rod of the fourth hydraulic rod is connected to the fourth disassembly plate 424. Thus, the fourth disassembly plate 424 is moved in the left and right direction by the extension and retraction of the fourth hydraulic rod.

[0050] In some embodiments, the photovoltaic recycling system 100 further includes a junction box disassembly assembly 8, which includes a mounting frame 31 and a disassembly hand 82. The mounting frame 31 is mounted on the frame 1 and located on the side of the first cutting assembly 3 away from the frame disassembly assembly 4. The disassembly hand 82 is mounted on the mounting frame 31 and is movable along the length of the mounting frame 31. The disassembly hand 82 moves vertically relative to the mounting frame 31 so that it can grasp the junction box on the photovoltaic panel to disassemble the junction box. Specifically, as Figure 2 and Figure 4 As shown, the mounting frame 31 is a frame extending in the left and right direction and fixed on the frame 1. The mounting frame 31 is located on the right side of the first cutting assembly 3 and has a linear slide rail extending in the left and right direction. The disassembly hand 82 is mounted on the mounting frame 31 by a cylinder, and the base of the cylinder cooperates with the linear slide rail and is driven by a drive component to move on the linear slide rail. This causes the cylinder to drive the disassembly hand 82 to move in the left and right direction on the mounting assembly to move to the top of the junction box. The cylinder drives the disassembly hand 82 to move downward so that the disassembly hand 82 moves downward and grabs the junction box. After grabbing the junction box, the cylinder moves upward to grab the junction box.

[0051] The present invention does not limit the disassembly hand 82, which can be a robotic arm. The embodiments of the present invention will not be described in detail.

[0052] In some embodiments, the photovoltaic recycling system 100 further includes a backsheet removal assembly 6, which is located downstream of the frame removal assembly 4. The backsheet removal assembly 6 includes a second cutting assembly 61, a backsheet peeling assembly 62, and a crystalline silicon collection assembly 63. All three assemblies are mounted on the frame 1. The second cutting assembly 61 cuts the backsheet of the photovoltaic panel, the backsheet peeling assembly 62 peels the cut backsheet from the photovoltaic panel, and the crystalline silicon collection assembly 63 collects the crystalline silicon from the peeled photovoltaic panel. Specifically, as... Figure 3 As shown, the second cutting component 61, the backsheet stripping component 62, and the crystalline silicon collection component 63 are all mounted on the frame 1 and located above the transport component 2. The second cutting component 61 can cut the front, back, left, and right sides of the photovoltaic panel backsheet, so that the backsheet and the main structure of the photovoltaic panel form a preset cutting gap, which facilitates the subsequent stripping operation.

[0053] After the second cutting component 61 completes the cutting operation, the back sheet peeling component 62 starts working. The back sheet peeling component 62 extends into the cutting gap and peels the entire back sheet off the photovoltaic panel completely by lifting, avoiding scratching or damage to the underlying crystalline silicon during the peeling process.

[0054] After the backsheet is stripped off, the exposed crystalline silicon continues to be transported along with the photovoltaic panel to the working area of ​​the crystalline silicon collection module 63. The crystalline silicon collection module 63 collects the crystalline silicon on the photovoltaic panel through vacuum adsorption, thereby separating the crystalline silicon from the remaining substrate of the photovoltaic panel, so that the crystalline silicon can be classified, purified and utilized as a resource in the future.

[0055] It is worth noting that the photovoltaic recycling system 100 in this embodiment of the invention is prior art. This embodiment of the invention will not be described in detail. For details of the specific structure, please refer to CN119281784A - A photovoltaic module backsheet stripping device and CN119549509A - A photovoltaic panel crystalline silicon recycling device and method.

[0056] In some embodiments, the photovoltaic recycling system 100 further includes a backsheet collection assembly 7, which is located downstream of and spaced apart from the backsheet disassembly assembly 6. The backsheet collection assembly 7 includes a collection box and a third transport member 71, which is positioned above the transport assembly 2. The transport direction of the third transport member 71 is opposite to that of the transport assembly 2. The backsheet peeling assembly 62 transports the peeled backsheet onto the third transport member 71. The collection box is located between the backsheet collection assembly 7 and the third transport member 71 so that the backsheet on the third transport member 71 can be transported into the collection box. Specifically, as shown... Figure 1As shown, the third transport component 71 is a belt conveyor, installed above the second transport component 22 and located behind the backsheet removal assembly 6. The collection box is a rectangular opening facing upwards, located between the backsheet collection assembly 7 and the third transport component 71. The second transport component 22 rotates clockwise to transport the photovoltaic panel from the front end to the rear end of the equipment. After the backsheet peeling operation is completed, the pressure shovel of the backsheet peeling assembly 62 can be moved above the third transport component 71 to accurately transfer the peeled backsheet onto the conveyor belt of the third transport component 71. The third transport component 71 rotates counterclockwise, driving the backsheet to be transported from back to front in reverse. Since the width of the peeled backsheet is smaller than the width between the two chains of the second transport component, the backsheet can pass through the gap between the two chains of the two second transport components and fall into the collection box below, realizing the automated collection of the backsheet. At the same time, only the glass substrate remains of the photovoltaic panel after the backsheet peeling is completed. This glass substrate will continue to be transported backwards with the second transport component 22 to enter the subsequent glass substrate collection process.
