Description

Technical Field

[0001] The present invention relates to the field of environmental protection technology, and in particular to a recycling and processing device and a working method for photovoltaic panel aluminum frame components. Background Art

[0002] After photovoltaic modules reach the end of their service life, they need to be recycled and reused for resource recycling and environmental protection. During the recycling process, in addition to dismantling the corresponding photovoltaic brackets to separate the photovoltaic panels, the aluminum alloy frames and junction boxes on the photovoltaic panels also need to be removed, and then the solar cells, tempered glass, backplane, etc. need to be separated. A Chinese patent (publication number CN116512339A) discloses a hot knife separation and recovery device for waste crystalline silicon photovoltaic panels. The device first heats the photovoltaic panels via a heating mechanism to soften the adhesive layer between the photovoltaic panel laminates. The panel is then conveyed to a separation mechanism through friction between a front conveyor mechanism and the cover glass and backplane. The separation mechanism then cuts the cover glass and separates it from the remaining laminates. The separated cover glass is then conveyed via a rear conveyor mechanism, resulting in a complete cover glass and the remaining laminates.

[0003] However, before separating the cover glass and the laminate, the aluminum alloy frame of the photovoltaic panel needs to be recycled. When disassembling the aluminum alloy frame, the frame is usually clamped with a frame claw, and then the frame is torn off the photovoltaic panel body. Since the strength and toughness of the aluminum alloy decrease after long-term service, the aluminum alloy frame is easily broken when separated by this clamping, pulling and tearing method, and it needs to be re-positioned and clamped. In addition, there are raised fins at the bottom of the aluminum alloy frame of the photovoltaic panel for auxiliary installation and fixation. This raised structure is difficult to match the clamp smoothly. Direct clamping can easily cause the raised fins to break, causing the clamp to slip, making it difficult to achieve the required clamping force, affecting the disassembly effect; and, during the pulling process, since the pulling direction is parallel to the clamping surface, excessive pulling force can easily cause the clamping position to loosen, causing the clamping position to scratch and damage the tempered glass, battery cells, and backplane, affecting the quality of recycled parts. At present, the removal process of the aluminum alloy frame of the photovoltaic panel has the problems of poor removal effect and low removal efficiency.

[0004] In addition, the junction box on the photovoltaic panel protrudes from the surface, and is currently mostly removed by knocking. During the knocking process, it is easy to cause vibration damage to other flat components of the photovoltaic panel, such as tempered glass and solar cells, affecting the quality of recycled parts. Moreover, since the junction box protrudes from the surface of the photovoltaic panel, it is inconvenient to place it on the flat fixture, and the clamping stability is poor, which affects the recycling efficiency. Summary of the Invention

[0005] The purpose of the present invention is to address the defects of the existing technology and provide a recycling and processing device and working method for photovoltaic panel aluminum frame components. The clamping part of the clamping assembly can be adjusted vertically according to the thickness of the photovoltaic panel to meet the clamping stability requirements. The cutting tool station integrates a sawing mechanism and a shoveling mechanism, and the two are distributed with a height difference. The sawing mechanism first pre-processes the frame, and the shoveling mechanism then performs a separation operation to achieve step-by-step disassembly. The first wedge-shaped tool and the second wedge-shaped tool of the shoveling mechanism are vertically spaced apart to form a channel for the frame to pass through. The first wedge-shaped tool can be adjusted in position by a vertical telescopic member, and cooperates with the second wedge-shaped tool to shovel from the inner circle of the frame into the space between the frame and the main body to achieve precise separation.

[0006] The first object of the present invention is to provide a recycling and processing device for photovoltaic panel aluminum frame components, which adopts the following scheme: include: A clamping assembly is mounted on the frame and is provided with a clamping portion for vertically adjusting the size; The cutting assembly includes a cutting tool table and an adjustment mechanism. The cutting tool table is installed on the frame through the adjustment mechanism to adjust the relative position of the cutting tool table and the clamping part; the cutting tool table includes a sawing mechanism and a shoveling mechanism with height difference distribution. The sawing mechanism is provided with a sawing tool. The shoveling mechanism includes a first wedge tool and a second wedge tool distributed vertically at intervals. The first wedge tool is connected to a vertical telescopic part. A channel is formed between the first wedge tool and the second wedge tool for the photovoltaic panel frame to pass through. The blades of the first wedge tool and the second wedge tool shovel from the inner circle of the photovoltaic panel frame into between the photovoltaic panel frame and the photovoltaic panel body.

[0007] Furthermore, the output end of the vertical telescopic member is connected to a slider, the first wedge-shaped tool is installed on the slider, the first wedge-shaped tool and the second wedge-shaped tool are located between the vertical telescopic member and the clamping part, and the blades of the first wedge-shaped tool and the second wedge-shaped tool are both facing the vertical telescopic member, and the side away from the blade is facing the clamping part.

[0008] Furthermore, the first wedge-shaped tool is located at the bottom of the slider, and the top of the slider is connected to a third wedge-shaped tool that extends toward the clamping part and protrudes out of the slider. The blade of the third wedge-shaped tool faces one side of the clamping part and is used to strip the junction box.

[0009] Furthermore, the sawing mechanism further comprises a sawing drive element, an output end of the sawing drive element is connected to the sawing tool, and the sawing drive element and the vertical telescopic member are spaced apart and distributed on the base of the cutting tool station.

[0010] Furthermore, vertically, the sawing tool is located between the base of the cutting tool station and the second wedge-shaped tool, and the sawing tool extends toward the clamping portion and protrudes out of the base of the cutting tool station to contact the raised fins at the bottom of the photovoltaic panel frame.

[0011] Furthermore, the adjustment mechanism includes a two-axis translation mechanism, the two-axis translation mechanism is installed on the frame, and the cutting tool platform is installed on the output end of the two-axis translation mechanism.

[0012] Furthermore, both sides of the clamping portion are respectively mounted on a two-axis translation mechanism, and a cutting tool stage is respectively mounted on the output end of each two-axis translation mechanism.

[0013] Furthermore, the clamping assembly includes an upper clamping plate and a lower clamping plate, and the upper clamping plate and the lower clamping plate are respectively connected to a clamping drive element. The clamping drive assembly connected to the lower clamping plate is installed on the rotating element to drive the lower clamping plate, the clamping drive element and the photovoltaic panel it carries to rotate horizontally.

[0014] A second object of the present invention is to provide a method for operating a device for recycling and processing photovoltaic panel aluminum frame assemblies, using the device for recycling and processing photovoltaic panel aluminum frame assemblies provided by the first object, comprising: The clamping assembly is started, and the clamping part is adjusted according to the specifications of the photovoltaic panel to clamp the photovoltaic panel; The adjustment mechanism drives the cutting tool table to move and adjusts the relative position between the cutting tool table and the clamping part; The sawing tool of the sawing mechanism saws the raised fins at the bottom of the photovoltaic panel frame; The shoveling mechanism is activated, and the photovoltaic panel frame passes through the channel between the first wedge-shaped tool and the second wedge-shaped tool. The vertical telescopic member drives the first wedge-shaped tool to perform vertical telescopic adjustment, so that the first wedge-shaped tool fits the top surface of the photovoltaic panel body, and the second wedge-shaped tool fits the bottom surface of the photovoltaic panel body, so that the blades of the two wedge-shaped tools are accurately shoveled from the inner circle of the photovoltaic panel frame to between the photovoltaic panel frame and the photovoltaic panel body, thereby peeling the photovoltaic panel frame from the body; The adjusting mechanism drives the cutting tool platform to move, so that the first wedge-shaped tool and the second wedge-shaped tool gradually move along the frame direction, so as to peel the photovoltaic panel frame from the photovoltaic panel body.

[0015] Furthermore, after one side frame is peeled off from the photovoltaic panel body, the posture of the photovoltaic panel is adjusted and the frames on the other sides of the photovoltaic panel are peeled off.

[0016] Compared with the prior art, the present invention has the following advantages and positive effects: To address the current issues of low efficiency and poor effectiveness in removing frames during photovoltaic panel recycling, the clamping assembly's clamping section can be vertically adjusted according to panel thickness, ensuring stable clamping. The cutting tool station integrates a sawing mechanism and a shoveling mechanism, both of which are arranged at different heights. The sawing mechanism first pre-processes the frame, followed by the shoveling mechanism for separation, achieving step-by-step disassembly. The shoveling mechanism's first and second wedge-shaped cutters are vertically spaced apart, forming a channel for the frame to pass through. The first wedge-shaped cutter, adjustable via a vertical telescopic member, cooperates with the second wedge-shaped cutter to shovel from the inner edge of the frame between the frame and the main body. Continuous advancement gradually separates the frame from the main body, achieving precise separation. The sawing pre-processing and progressive separation of the wedge-shaped cutters reduce stress concentration on the aluminum alloy frame during removal, preventing breakage due to material degradation, reducing repetitive work, and improving disassembly efficiency. The vertically adjustable clamping section and the wedge-shaped cutter's inner force application effectively avoid the raised fin structure at the bottom of the frame, ensuring a stable and reliable disassembly process.

[0017] The first and second wedge-shaped cutters are positioned between the vertical telescopic member and the clamping portion, with the blades facing the telescopic member and the sides facing away from the blades toward the clamping portion. This arrangement ensures that when the cutters penetrate the frame, the force is directed toward the outside of the photovoltaic panel, preventing compressive stress on the tempered glass and solar cells. Furthermore, the reverse orientation of the cutter edges (toward the telescopic member) ensures that the frame material deforms outward during penetration, reducing the risk of internal damage.

[0018] The third wedge-shaped tool extends out of the slider toward the clamping portion, with its blade facing the junction box (typically located at the back edge of the photovoltaic panel). When the slider moves with the vertical telescopic member, the extended length of the third wedge-shaped tool ensures that the blade can reach the connection area between the junction box and the photovoltaic panel.

DETAILED DESCRIPTION

[0027] Example 1 In a typical embodiment of the present invention, Figures 1-6 As shown, a recycling and processing device for photovoltaic panel aluminum frame components is provided.

[0028] After the photovoltaic panel 7 has been in service for a long time, the strength and toughness of the aluminum alloy frame decrease. The traditional clamping and pulling method can easily cause the frame to break, and repeated positioning and clamping are required, which is inefficient. The raised fin structure at the bottom of the frame makes it difficult for the clamp to match effectively, which can easily cause the clamp to slip and cannot provide sufficient removal force. The pulling direction is parallel to the clamping surface. Excessive removal force may cause the clamping position to loosen, scratching core components such as tempered glass and battery cells, affecting the recycling quality. Based on this, this embodiment provides a recycling and processing device for photovoltaic panel aluminum frame assemblies. The clamping part of the clamping assembly 3 can be adjusted vertically according to the thickness of the photovoltaic panel 7 to ensure stable clamping of photovoltaic panels 7 of different specifications and avoid clamping failure caused by raised fins; the cutting tool station 4 integrates a sawing mechanism and a shoveling mechanism, and the two are distributed in a height difference. The sawing mechanism first pre-processes the frame, and the shoveling mechanism then performs a separation operation to achieve step-by-step disassembly. The first wedge tool 408 and the second wedge tool 409 of the shoveling mechanism are vertically spaced to form a channel for the frame to pass through. The first wedge-shaped tool 408 can adjust its position through the vertical telescopic member 404 and cooperate with the second wedge-shaped tool 409 to shovel into the space between the frame and the main body from the inner circle of the frame to achieve precise separation.

[0029] Specifically, the recycling and processing device for the photovoltaic panel aluminum frame assembly includes a clamping assembly 3 and a cutting assembly. The clamping assembly 3 is mounted on the frame 2 and is provided with a clamping portion for vertical size adjustment. The cutting assembly includes a cutting tool table 4 and an adjustment mechanism. The cutting tool table 4 is mounted on the frame 2 via the adjustment mechanism to adjust the relative position of the cutting tool table 4 and the clamping portion. The cutting tool table 4 includes a sawing mechanism and a shoveling mechanism with a height difference. The sawing mechanism is provided with a sawing tool 401. The shoveling mechanism includes a first wedge-shaped tool 408 and a second wedge-shaped tool 409 vertically spaced apart. The first wedge-shaped tool 408 is connected to a vertical telescopic member 404. A channel is formed between the first wedge-shaped tool 408 and the second wedge-shaped tool 409 for the photovoltaic panel 7 frame to pass through. The blades of the first wedge-shaped tool 408 and the second wedge-shaped tool 409 shovel from the inner circle of the photovoltaic panel 7 frame into the space between the photovoltaic panel 7 frame and the photovoltaic panel 7 body.

[0030] The clamping assembly 3 adjusts its clamping dimensions according to the thickness of the photovoltaic panel 7, firmly clamping the panel 7 and preventing it from shaking during disassembly. An adjustment mechanism drives the cutting tool stage 4, aligning the sawing mechanism with the frame to be processed. The sawing tool 401 partially cuts the aluminum alloy frame, weakening the connection between the frame and the main body and preparing for subsequent scraping and separation.

[0031] The sawn frame enters the passage between the first and second wedge-shaped cutters 409. The vertical telescopic member 404 drives the first wedge-shaped cutter 408 downward, cooperating with the second wedge-shaped cutter 409 to dig the edge of the cutting edge from the inner edge of the frame into the junction of the frame and the main body. With continued advancement, the frame is gradually separated from the main body, completing the disassembly process.

[0032] Through sawing pretreatment and the progressive separation of the wedge-shaped tool, the stress concentration of the aluminum alloy frame during the dismantling process is reduced, the problem of breakage caused by the degradation of material properties is avoided, repeated operations are reduced, and the dismantling efficiency is improved. The vertically adjustable clamping part and the wedge-shaped tool applying force from the inner circle effectively avoid the raised fin structure at the bottom of the frame, ensuring the stability and reliability of the dismantling process. The shoveling direction of the wedge-shaped tool is perpendicular to the surface of the photovoltaic panel 7, and the dismantling force acts on the inside of the frame, avoiding scratches and damage to core components such as tempered glass and solar cells, and improving the quality and reuse rate of recycled parts.

[0033] The first and second wedge-shaped cutters 408, 409 are positioned between the vertical telescopic member 404 and the clamping portion, with their blades facing the telescopic member and their sides facing away from the blades toward the clamping portion. This ensures that when the cutters penetrate the frame, the force is directed toward the outside of the photovoltaic panel 7, preventing compressive stress on the tempered glass and solar cells. Furthermore, the reverse orientation of the cutter edges (toward the telescopic member) ensures that the frame material deforms outward during penetration, reducing the risk of internal damage.

[0034] like Figure 5 As shown, the output end of the vertical telescopic member 404 is connected to a slider 406, and a first wedge-shaped tool 408 is mounted on the slider 406. The first wedge-shaped tool 408 and the second wedge-shaped tool 409 are located between the vertical telescopic member 404 and the clamping portion, and the blades of the first wedge-shaped tool 408 and the second wedge-shaped tool 409 are both facing the vertical telescopic member 404, and the side away from the blades is facing the clamping portion. The vertical telescopic member 404 can be equipped with a hydraulic cylinder. In order to guide the slider 406, a slider guide frame 405 with an opening is provided around the vertical telescopic member 404. The slider 406 passes through the slider guide frame 405 and is connected to the first wedge-shaped tool 408.

[0035] The first wedge-shaped tool 408 is located at the bottom of the slider 406. The top of the slider 406 is connected to a third wedge-shaped tool 407 that extends toward the clamping part and protrudes out of the slider 406. The blade of the third wedge-shaped tool 407 faces one side of the clamping part and is used to peel off the junction box.

[0036] The third wedge-shaped cutter 407, extending from the top of the slider 406, forms a longitudinally arranged structure with the first wedge-shaped cutter 408 and the second wedge-shaped cutter 409 to prevent interference. The cutting edge of the third wedge-shaped cutter 407 faces the clamping portion. The third wedge-shaped cutter 407 is mounted on the top of the slider 406, forming a vertically offset arrangement with the first wedge-shaped cutter 408 at the bottom. This ensures that when the same slider 406 is performing the frame removal operation, the third wedge-shaped cutter 407 reaches the junction box position simultaneously, eliminating the need for an additional lifting mechanism and streamlining the equipment structure.

[0037] The third wedge-shaped cutter 407 extends out of the slider 406 toward the clamping portion, with its blade facing the junction box (typically located at the back edge of the photovoltaic panel 7). When the slider 406 moves with the vertical telescopic member 404, the extended length of the third wedge-shaped cutter 407 ensures that the blade can reach the connection area between the junction box and the photovoltaic panel 7.

[0038] The sawing mechanism also includes a sawing drive element, the output of which is connected to a sawing tool 401. The sawing drive element and a vertical telescopic member 404 are spaced apart on the base of the cutting tool station 4. The sawing drive element comprises a motor 403 and a gearbox 402. The output of the motor 403 is connected to the sawing tool 401 through the gearbox 402. The sawing tool 401 is a chain saw blade, which is driven by the motor 403 to rotate and cut the raised fins of the photovoltaic panel 7. A second wedge-shaped tool 409 is mounted on the base via a fixing base 410.

[0039] The sawing tool 401 is located between the base and the second wedge-shaped tool 409, and protrudes out of the base, so that it can accurately contact the raised fins at the bottom of the frame, solving the problem that traditional clamps are difficult to handle raised structures. By sawing the fins first, it not only eliminates the clamping obstacles, but also weakens the connection strength between the frame and the main body, creating conditions for the subsequent wedge-shaped tool to cut in.

[0040] The sawing drive elements and the vertical telescopic member 404 are spaced apart on the base to avoid vibration interference. The high-frequency vibrations generated during sawing are transmitted to the frame 2 through the independent support structure, while the linear motion of the vertical telescopic member 404 is not affected, ensuring the stability of the wedge cutter's cutting.

[0041] like Figure 1 、 Figure 2 and Figure 6 The adjustment mechanism includes a two-axis translation mechanism mounted on the frame 2, with the cutting tool stage 4 mounted at the output end of the two-axis translation mechanism. The clamping portion is mounted on either side of the two-axis translation mechanism, with the cutting tool stage 4 mounted at the output end of each two-axis translation mechanism. Specifically, the two-axis translation mechanism can utilize a combination of screw and slider mechanisms. The two-axis translation mechanisms on either side of the clamping portion can independently control the X and Y axis motion of the cutting tool stage 4. Through synchronous or asynchronous operation, parallel or sequential processing of the two opposing frames of the photovoltaic panel 7 can be achieved.

[0042] In this embodiment, the two-axis translation mechanism is a combination of a longitudinal screw guide 6 and a transverse screw guide 5. The transverse screw guide 5 is fixed at the middle position on both sides of the frame 2. A nut slider 606 is slidably fitted on the transverse screw guide 5 to form a screw slider mechanism. Two cylindrical guides are equidistantly distributed on both sides of the transverse screw guide 5 and are parallel to the transverse screw guide 5. Longitudinal screw guide 6 movement guide grooves corresponding to the cylindrical guides are provided on both sides of the bottom of the longitudinal screw guide 6, and the bottom is connected to the nut slider 606 fitted with the transverse screw guide 5. The longitudinal screw guide 6 as a whole can move laterally under the drive of the nut slider 606 fitted with the transverse screw guide 5 and the guidance of the cylindrical guides on both sides, thereby driving the cutting tool stage 4 to achieve lateral movement; the cutting tool stage 4 is connected to the nut slider 606 of the longitudinal screw guide 6, and the cutting tool stage 4 can move longitudinally driven by the nut slider 606 of the longitudinal screw guide 6.

[0043] Specifically, such as Figure 6As shown, both the longitudinal screw guide 6 and the transverse screw guide 5 comprise a screw 604 mated with a nut slider 606 and guide rails located on either side of the screw 604. The ends of the screw 604 are mounted via bearing supports 603 to maintain their positions. The screw 604 is driven by a servo motor 601 connected to its end. The bearing supports 603 are fitted with screw end caps 602, through which the screw 604 passes. Sliders 605 on either side of the slideway are slidably fitted to the two guide rails, serving as output ends for connection to the longitudinal screw guide 6 or the cutting tool stage 4. A screw nut 609, mating with the screw 604, is fixed to the nut slider 606.

[0044] The lower clamping plate 303 rotates horizontally via a rotating element, allowing the photovoltaic panels 7 to be disassembled in multiple directions without repositioning. After processing one frame, it can be rotated 90 degrees to continue processing the adjacent frame, eliminating the need for multiple handling and re-clamping required by traditional equipment and reducing positioning errors.

[0045] When the vertically telescopic member 404 drives the first wedge-shaped cutter 408 to cut, the force is transmitted to the cutter through the slider 406, acting on the interface between the frame and the adhesive layer. Due to the design of the cutter's cutting edge angle (typically 30°-45°), the cutting force is decomposed into a horizontal separation force and a vertical support force. The vertical component is offset by the second wedge-shaped cutter 409, while the horizontal component pushes the frame apart from the main body. This force decomposition mechanism effectively reduces the total power required for disassembly.

[0046] Through the combined action of sawing and wedge cutting, the device can effectively process aluminum alloy frames with complex structures such as reinforcing ribs and flanges. Because the integrity of the frame is maintained during the disassembly process, the recycled aluminum alloy material can enter the melting process without additional shaping, saving post-processing costs. The combination of a two-axis translation mechanism and a rotary element provides the hardware foundation for the subsequent integration of machine vision and AI algorithms. By identifying the degree of aging on the frame surface, the sawing depth and wedge cutting speed are automatically adjusted, achieving adaptive disassembly.

[0047] Through the synergistic action of sawing and upper and lower wedge-shaped blades, a controllable force is applied to the frame in three dimensions, transcending the limitations of traditional two-dimensional disassembly. This system is particularly suitable for processing complex structures and aged materials. Independent cutting tool stations (4) on either side of the clamping unit, combined with a rotating element, enable the device to achieve "single clamping, multi-surface processing" capabilities, achieving modularization and parallelization of the disassembly process. The sawing mechanism's pre-treatment of the raised fins and the wedge-shaped blade's progressive cutting enable the device to accommodate localized defects in the frame material (such as oxide layers and microcracks), enhancing the system's robustness.

[0048] The pre-processing of the photovoltaic panel 7 frame by the sawing mechanism solves the two core problems when the wedge tool is directly operated. Its logic is to provide conditions for the subsequent precise separation of the wedge tool through a combined strategy of pre-processing obstacles and reducing the difficulty of the operation.

[0049] The untreated aluminum alloy frame has a complete overall structure and is tightly connected to the adhesive layer of the photovoltaic panel 7 body. If the wedge-shaped tool is cut directly into it, it needs to maintain a large opening to accommodate the frame and apply the separation force. The larger the opening, the worse the stability of the tool, and it is easy for the frame to deform out of control due to uneven force. After the sawing mechanism partially cuts the frame with the sawing tool 401, the structural integrity of the frame is broken and the connection strength of the adhesive layer is weakened. At this time, the wedge tool only needs a smaller opening to fit into the gap after the cut. At the same time, the notch produced by the cutting provides an initial entry fulcrum for the wedge tool, reducing the travel of the tool to "open" the frame, indirectly reducing the requirements for the tool opening, so that the first wedge tool 408 and the second wedge tool 409 can complete the separation action in a more compact posture.

[0050] From the perspective of avoiding interference from raised fins, the raised fins at the bottom of the frame are the main obstacle to the operation of traditional wedge-shaped tools. The presence of raised fins will prevent the frame from entering the tool channel smoothly, and may even jam the tool or cause wear on the tool blade. The sawing tool 401 of the sawing mechanism is designed to precisely correspond to the position of the fins due to its height, and the fins can be directly cut and removed in the preprocessing stage, or a notch can be cut at the connection between the fins and the frame body. The influence of the fins on subsequent processes is eliminated, and the channel of the wedge-shaped tool is no longer blocked by the fins. The first wedge-shaped tool 408 and the second wedge-shaped tool 409 can move smoothly along the inner circle of the frame, and the blade can be precisely aligned with the adhesive interface between the frame and the photovoltaic panel 7 body, avoiding tool offset or operation interruption caused by fin interference.

[0051] In essence, it breaks down the complex disassembly task into two steps: "obstacle removal" and "core separation". By specifically addressing the structural defects and connection strength of the frame, the working environment of the wedge tool is made more controllable, ultimately achieving efficient and stable frame removal.

[0052] Figure 3 and Figure 4 The clamping assembly 3 includes an upper clamping disc 302 and a lower clamping disc 303. The upper clamping disc 302 and the lower clamping disc 303 are respectively connected to clamping drive elements. The clamping drive assembly connected to the lower clamping disc 303 is installed on the rotating element to drive the lower clamping disc 303, the clamping drive element and the photovoltaic panel 7 carried thereon to rotate horizontally.

[0053] The upper clamping disc 302 and the lower clamping disc 303 are parallel disc-shaped structures, and their surfaces are usually covered with a flexible material such as rubber or silicone to increase friction with the photovoltaic panel 7 and prevent scratches. The diameter of the upper clamping disc 302 and the lower clamping disc 303 is smaller than the size of the photovoltaic panel 7, such as the edge area of ​​the photovoltaic panel 7.

[0054] The upper clamping disc 302 and the lower clamping disc 303 are each connected to an independent clamping drive element (such as an electric push rod, hydraulic cylinder, or servo motor 601), enabling vertical relative motion. In this embodiment, the clamping drive element is a hydraulic cylinder. The upper clamping disc 302 is connected to an upper hydraulic clamping cylinder, and the lower clamping disc 303 is connected to a lower hydraulic clamping cylinder 304. The rotary element is a hydraulic turntable 306, which is mounted to the frame 2 via a hydraulic turntable mounting platform 305. The lower hydraulic clamping cylinder 304 is mounted on the hydraulic turntable 306. The clamping force is controlled by the drive element to meet the clamping requirements of photovoltaic panels 7 of varying thicknesses. A hydraulic power source 1, such as a hydraulic pump, is provided to provide hydraulic power to the clamping drive element and the rotary element.

[0055] The lower clamping plate 303 and its drive assembly are mounted on a rotating element (e.g., a rotary servo motor 601 or indexing plate), enabling 360° horizontal rotation. Rotational accuracy is typically controlled within ±0.1°, ensuring that subsequent cutting components are accurately aligned with the photovoltaic panel 7 frame.

[0056] Example 2 In another typical embodiment of the present invention, Figures 1-6 As shown, a working method of a photovoltaic panel aluminum frame assembly recycling and processing device is provided, using the photovoltaic panel aluminum frame assembly recycling and processing device as in Example 1.

[0057] A method for recycling and processing a photovoltaic panel aluminum frame assembly comprises: The clamping assembly 3 is started, and the clamping part is adjusted according to the specifications of the photovoltaic panel 7 to clamp the photovoltaic panel 7; The adjustment mechanism drives the cutting tool stage 4 to move and adjusts the relative position between the cutting tool stage 4 and the clamping portion; The sawing tool 401 of the sawing mechanism saws the raised fins at the bottom of the frame of the photovoltaic panel 7; The shoveling mechanism is in motion, and the frame of the photovoltaic panel 7 passes through the channel between the first wedge-shaped tool 408 and the second wedge-shaped tool 409. The vertical telescopic member 404 drives the first wedge-shaped tool 408 to perform vertical telescopic adjustment, so that the first wedge-shaped tool 408 is in contact with the top surface of the photovoltaic panel 7 body, and the second wedge-shaped tool 409 is in contact with the bottom surface of the photovoltaic panel 7 body, so that the blades of both are accurately shoveled from the inner circle of the frame of the photovoltaic panel 7 to between the frame of the photovoltaic panel 7 and the main body of the photovoltaic panel 7, thereby peeling the frame of the photovoltaic panel 7 from the main body; The adjustment mechanism drives the cutting tool stage 4 to move, so that the first wedge-shaped tool 408 and the second wedge-shaped tool 409 gradually move along the frame direction, so as to peel the photovoltaic panel 7 frame from the photovoltaic panel 7 body.

[0058] After one side frame is peeled off from the main body of the photovoltaic panel 7 , the posture of the photovoltaic panel 7 is adjusted, and the frames on the other sides of the photovoltaic panel 7 are peeled off.

[0059] The third wedge-shaped cutter 407 extends out of the slider 406 toward the clamping portion, with its blade facing the junction box (typically located at the back edge of the photovoltaic panel 7). When the slider 406 moves with the vertical telescopic member 404, the extended length of the third wedge-shaped cutter 407 ensures that the blade can reach the connection area between the junction box and the photovoltaic panel 7.

[0060] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of protection of the present invention.
