[0021] Specifically, the junction box and aluminum frame removal device for photovoltaic modules, through the design of the container-type installation body 1, not only provides a stable and enclosed installation environment for all mechanisms, effectively isolating them from external dust, rain, and other interferences, but also enables convenient movement and rapid deployment of the device through the standardized container structure, meeting the usage needs of different recycling scenarios.

This completely eliminates reliance on manual operation, reducing the labor intensity of operators, avoiding damage to photovoltaic modules caused by manual operation, and eliminating safety hazards from manual contact with cutting, milling, and other dangerous operations, providing a reliable equipment foundation for large-scale industrial photovoltaic module recycling.

[0022] like Figure 3As shown, the transmission mechanism 3 includes a support frame 31, two transmission lines 32, a transmission belt speed-regulating motor 33, an intermediate roller 34, a centering component 35, a connecting frame 36, a measuring grating 37, a laser sensor, and a clamping component 38. The transmission belt speed-regulating motor 33 drives the two transmission lines 32, which are mounted on the support frame 31. The intermediate roller 34 is positioned between the two transmission lines 32, providing a space for the lifting mechanism 7 to be installed. The centering component 35, connecting frame 36, measuring grating 37, laser sensor, and clamping component 38 are all mounted on the support frame 31. The centering component 35 aligns the centerline of the photovoltaic module with the centerline of the transmission channel of the transmission line 32. The measuring grating 37 is used for photovoltaic module positioning detection, and the laser sensor is used to detect the presence and transmission status of the photovoltaic module. The clamping component 38 cooperates with the lifting mechanism 7 to clamp the photovoltaic module. Specifically, the conveyor belt speed-regulating motor 33 drives the two transmission lines 32 to move, and can adjust the transmission speed of the transmission lines 32 according to actual production needs to ensure the stability and accuracy of photovoltaic module transmission. The two transmission lines 32 are mounted on the support frame 31, with the intermediate roller 34 positioned between them, providing a space for the lifting mechanism 7 to be installed. The centering component 35, connecting frame 36, measuring grating 37, laser sensor, and clamping component 38 are all mounted on the support frame 31. The centering component 35 aligns the centerline of the photovoltaic module with the centerline of the transmission channel of the transmission line 32, ensuring accurate positioning of the photovoltaic module during transmission and providing a good positioning basis for subsequent dismantling operations. The measuring grating 37 is used for photovoltaic module positioning detection, accurately detecting the position of the photovoltaic module on the transmission line 32 and providing accurate position signals for the actions of each mechanism. The laser sensor detects the presence and transmission status of photovoltaic modules. When a photovoltaic module is detected entering the transmission line 32 or being transmitted to a designated position, it promptly sends a signal to control the corresponding actions of each mechanism. The clamping assembly 38 specifically includes multiple hydraulic cylinders. When the lifting mechanism 7 lifts the photovoltaic module to the clamping position, the multiple hydraulic cylinders cooperate with the lower clamping member 74 of the lifting mechanism 7 and the upper clamping member 361 of the connecting frame 36 to clamp the photovoltaic module from the top and bottom directions, thereby increasing the clamping force of the photovoltaic module, preventing the photovoltaic module from shifting during the dismantling operation, and ensuring the smooth progress of the dismantling operation.

[0023] More specifically, the transmission line 32 is a belt conveyor driven by a speed-regulating motor. The two belt conveyors on either side are connected by a chain to ensure perfectly synchronized transmission. Brushes and receiving boxes are installed below the output ends of both transmission lines 32. During photovoltaic module transmission, foreign objects or debris may fall onto the belts. If not cleaned promptly, this could damage the belts. The brushes remove these foreign objects into the receiving boxes, ensuring the cleanliness of the transmission lines 32. The transmission lines 32 are made of polyurethane, with a maximum effective width of 1200mm and a transmission surface height of approximately 1018.5mm from the ground. The intermediate roller 34 is a non-powered, rubber-coated intermediate roller. There are four centering components 35: two located on the transmission lines 32, one at the junction box removal mechanism 4, and one at the input port of the container-type installation body 1. These components can be used to center and clamp the photovoltaic modules at different positions. Since the photovoltaic modules need to be centered at different positions, at least two centering components 35 are applied to the photovoltaic modules simultaneously during centering. The support frame 31 is made of 60×60×2mm rectangular tube welded together, made of Q235B material, and the surface is painted for corrosion protection.

The connecting frame 36 is provided with an upper clamping member 361 corresponding to the lower clamping member 74. Specifically, the lifting electric cylinder 72 drives the positioning seat 71 and the lower clamping member 74 to move up and down, thereby adjusting the photovoltaic module in a vertical position. The rotary slide 73 drives the lower clamping member 74 to move around, thereby rotating the photovoltaic module so that different faces and positions of the photovoltaic module can face the corresponding dismantling mechanism, meeting the needs of different dismantling operations. In addition, the connecting frame 36 is provided with an upper clamping member 361 corresponding to the lower clamping member 74. The upper clamping member 361 and the lower clamping member 74 cooperate with each other to clamp the photovoltaic module more firmly and prevent the photovoltaic module from loosening or falling during lifting and rotation.

A servo electric cylinder 53 drives the angle grinder 55 to move vertically, adjusting its height so that it can accurately contact the corner pieces of the photovoltaic module's aluminum frame and perform the cutting operation. A pneumatic slide 54 drives the angle grinder 55 to rotate, adjusting its cutting angle according to the corner piece's angle to ensure the integrity and accuracy of the cut. The angle grinder 55 cuts the corner pieces of the photovoltaic module's aluminum frame using a high-speed rotating grinding disc, preparing for subsequent aluminum frame removal.

The milling cutter drive motor 65 drives the milling cutter 66 to rotate, providing milling power to the milling cutter 66. The high-speed rotating milling cutter 66 removes the residual adhesive layer and backsheet. The milling cutter 66 is used to mill the residual adhesive layer and backsheet after the aluminum frame of the photovoltaic module is removed, restoring the glass surface of the photovoltaic module to a clean state, facilitating subsequent recycling.

[0028] like Figure 4 , Figure 9 and Figure 10As shown, the gripper mechanism 8 includes a gripper hydraulic cylinder 81, a gripper positioning frame 82, and multiple gripper actuation components mounted on the gripper positioning frame 82. Each gripper actuation component includes a mounting base 83, an upper cylinder 84, a gripper piece 85, an upper guide plate 86, a lower guide plate 87, and an ejection cylinder 88. A gripper hydraulic cylinder 81 is mounted on a connecting frame 36, and its output end is connected to a gripper positioning frame 82.

Specifically, the gripper component 85 has a half-tile structure, and the mounting base 83 is mounted on the gripper positioning frame 82 to provide mounting support for other components of the gripper actuator. The upper cylinder 84 drives the gripper 85 to rotate, opening and closing it to clamp and release the aluminum frame. The upper guide plate 86 and lower guide plate 87 are both mounted on the mounting base 83. The upper guide plate 86 assists in removing the aluminum frame, guiding and assisting the gripper 85 during the removal process, ensuring smooth removal. Specifically, when removing a short frame after removing a long frame, which may warp, the upper guide plate 86 guides the aluminum frame into the gripper 85. The lower guide plate 87 guides the photovoltaic module into the gripper mechanism 8, ensuring accurate entry into its working area. The ejector cylinder 88 ejects the aluminum frame of the photovoltaic module.

In this embodiment, there are four gripper actuators, ensuring that all four gripper actuators can perform clamping action when removing the aluminum frame on the long side; when removing the aluminum frame on the short side, the two middle gripper actuators can be used for clamping action.

[0029] like Figure 1 and Figure 2As shown, the receiving mechanism 9 includes an aluminum frame receiving trolley 91 and a junction box trolley 92. The aluminum frame receiving trolley 91 receives the aluminum frames removed by the gripper mechanism 8; the junction box trolley 92 receives the junction boxes removed by the junction box removal mechanism 4. After the gripper mechanism 8 removes the aluminum frame and pushes it out through the push-out cylinder 88, the aluminum frame falls into the aluminum frame receiving trolley 91, facilitating subsequent recycling. The junction box removal mechanism 4 removes the junction box and transports it to the junction box trolley 92 for collection, facilitating sorting and recycling. Both the aluminum frame receiving trolley 91 and the junction box trolley 92 adopt an external frame structure welded from angle steel, with an internal stainless steel wire mesh basket. They are equipped with casters at the bottom and handles at both ends for easy handling by operators.

[0030] In addition, the containerized installation body 1 includes a base, two sliding doors, a ventilation system, and an inspection door. The two sliding doors are located on both sides of the base, corresponding to the inlet and outlet channels of the photovoltaic modules, respectively. The ventilation system is connected to the base to create a negative pressure environment inside. The inspection door allows personnel to enter the base for operation. Specifically, the containerized installation body 1 serves as the installation foundation and protective shell for the entire device, providing a stable installation environment for each component and effectively protecting them from external environmental interference and damage. The two sliding doors, located on both sides of the base, correspond to the inlet and outlet channels of the photovoltaic modules, facilitating their entry and exit. The ventilation system, connected to the base, creates a negative pressure environment inside, promptly drawing in and treating harmful substances such as dust and debris generated during dismantling, improving the working environment and reducing environmental pollution. The inspection door allows personnel to enter the base for equipment inspection, maintenance, and upkeep, ensuring the normal operation of the equipment.

[0031] The front roller 2 is located on the outside of the container-type installation body 1. It is mainly used to transport photovoltaic modules into the container-type installation body 1, and plays a guiding and auxiliary role in the transmission, so that the photovoltaic modules can smoothly enter the subsequent transmission mechanism 3.

[0032] The hydraulic system of this demolition device uses a hydraulic workstation equipped with an electronic pressure gauge that can communicate with a PLC to monitor the hydraulic system pressure in real time. It also features a pressure regulating valve for pressure adjustment as needed. The oil tank is equipped with an electronic level gauge to monitor the oil level limits. The circuit control solenoid valve is a three-position four-way solenoid valve with a center-sealed structure, which can maintain the current state of the hydraulic cylinder in case of abnormal oil circuit pressure. The solenoid valve is a proportional solenoid valve, which controls the extension distance of the hydraulic cylinder by adjusting the valve flow rate, ensuring motion accuracy.

[0033] In this embodiment, a method for removing the junction box and aluminum frame of a photovoltaic module is also constructed, which is based on the above-mentioned device for removing the junction box and aluminum frame of a photovoltaic module, and includes the following steps: S1. Input the photovoltaic module and place it into the transmission mechanism 3. Start the transmission mechanism 3 to transfer the photovoltaic module. S2. The photovoltaic module is positioned by laser sensor and measuring grating 37. The front corner of the aluminum frame of the photovoltaic module is cut by corner cutting mechanism 5. Then the junction box is removed by junction box removal mechanism 4 and transferred to junction box trolley 92. Then the rear corner of the aluminum frame of the photovoltaic module is cut by corner cutting mechanism 5. S3. After the corner pieces of the aluminum frame of the photovoltaic module are cut, the photovoltaic module is transferred to the aluminum frame removal position through the transmission mechanism 3. The lifting mechanism 7 drives the photovoltaic module to rise and rotate. The clamping component 38 of the transmission mechanism 3 clamps the photovoltaic module. The gripper mechanism 8 clamps and removes the aluminum frame of the photovoltaic module. After the aluminum frame of the photovoltaic module is removed, the lifting mechanism 7 drives the photovoltaic module to reset. S4. The photovoltaic module is transferred to the milling position through the transmission mechanism 3, and the residual adhesive layer and back sheet after the aluminum frame of the photovoltaic module are removed are milled by the milling cutter mechanism 6. S5. After the photovoltaic module is milled, it is transferred to the next device through the transmission mechanism 3.

[0034] Understandably, the removal method of the junction box and aluminum frame removal device for photovoltaic modules follows a process of loading, cutting, junction box removal, frame removal, milling, and photovoltaic module output. The processes are closely linked, with no redundant steps, thus improving overall work efficiency. Precise positioning via laser sensors and measuring grating 37 ensures accurate timing of each process, reducing operational errors. The rotational movement of the lifting mechanism 7 enables frame removal in different directions without requiring adjustments to the equipment structure, simplifying the operation process. Full automation reduces manual intervention and labor intensity, while also avoiding module damage caused by manual operation.

[0035] Specifically, in step S1, the dimensions of the photovoltaic module to be processed are manually input into the equipment control system, the sliding door of the feed end of the container-type installation body 1 is opened, the photovoltaic module is placed on the front roller 2, the module is pushed into the transmission line 32 of the transmission mechanism 3, the transmission belt speed regulating motor 33 is started, and the transmission line 32 drives the photovoltaic module to be transported into the equipment.

[0036] In step S2, two laser sensors are used to detect the photovoltaic module. The two laser sensors are a first laser sensor and a second laser sensor. Step S2 includes: S21. When both the first laser sensor and the second laser sensor are triggered, the junction box removal mechanism 4 descends to the blocking position, and the centering component 35 centers the photovoltaic module. S22, When the measuring grating 37 detects that the photovoltaic module has reached the front cutting position, the transmission line 32 stops, the corner cutting mechanism 5 cuts the front corner of the aluminum frame of the photovoltaic module, after cutting the angle grinder 55 rises, and the transmission line 32 continues to transmit; S23. When the first laser sensor is not triggered and the second laser sensor is triggered, the transmission line 32 stops, the junction box removal mechanism 4 descends to the removal position, the scraper 48 closes to remove the junction box and then rises, and the rodless cylinder 42 drives the junction box to the junction box trolley 92 position to release the material. S24. After the junction box is removed, the transmission line 32 continues to start. When the measuring grating 37 detects that the photovoltaic module has reached the rear cutting position, the transmission line 32 stops, and the corner cutting mechanism 5 cuts the rear corner of the aluminum frame of the photovoltaic module.

[0037] In the specific process, S21. When both the first laser sensor and the second laser sensor on the transmission mechanism 3 are triggered, the vertical drive cylinder 44 of the junction box removal mechanism 4 drives the mounting box 46 to descend to the blocking position to prevent the photovoltaic module from continuing to be transmitted; at the same time, the electric cylinder and the pneumatic cylinder of the centering module 35 are activated to center and clamp the photovoltaic module. S22. The measuring grating 37 starts detection. When the photovoltaic module is detected to have been transmitted to the front cutting position, the transmission line 32 stops. The double slider module 52 of the corner cutting mechanism 5 adjusts the position of the angle grinder 55. The servo electric cylinder 53 drives the angle grinder 55 to descend and cut the L-shaped corner piece at the front end of the photovoltaic module to the set depth. After the cutting is completed, the angle grinder 55 rises, the transmission line 32 continues to transmit, and at the same time the pneumatic slide table 54 drives the angle grinder 55 to rotate 90°. The double slider module 52 adjusts the position of the angle grinder 55 in preparation for subsequent cutting. S23. When the first laser sensor is not triggered but the second laser sensor is still triggered, the transmission line 32 stops after a delay; the vertical drive cylinder 44 of the junction box removal mechanism 4 drives the mounting box 46 to descend to the removal position, and the horizontal drive cylinder 47 drives the two scrapers 48 to close, removing the junction box and cutting the connecting cable; then the vertical drive cylinder 44 drives the mounting box 46 to rise, the rodless cylinder 42 drives the positioning plate 43 to move above the junction box trolley 92, and the horizontal drive cylinder 47 drives the scrapers 48 to open, and the junction box falls into the junction box trolley 92; S24. After the junction box is unloaded, the rodless cylinder 42 drives the positioning plate 43 to reset, and the transmission line 32 starts. The measuring grating 37 detects again. When the photovoltaic module is transmitted to the rear cutting position, the transmission line 32 stops. The corner cutting mechanism 5 cuts the L-shaped corner piece at the rear of the photovoltaic module. After the cutting is completed, the angle grinder 55 rises and resets, and the transmission line 32 continues to transmit.

[0038] Understandably, in step S2, the trigger status of two laser sensors determines the component position, enabling precise material blocking of the junction box removal mechanism 4 and stopping of the transmission line 32, thus improving the accuracy of process connection. The corner pieces are cut in two steps, front cutting and rear cutting, ensuring that both the front and rear frames of the photovoltaic module can be smoothly removed, avoiding difficulties in frame removal due to incomplete corner piece cutting. The centering action of the component 35 before cutting ensures accurate corner piece cutting position, reduces cutting deviation, and improves the efficiency of subsequent frame removal.

[0039] Step S3 includes: S31, the lifting mechanism 7 rises to the rotating position, rotating the photovoltaic module so that the short side of the aluminum frame faces the gripper mechanism 8; S32, the lifting mechanism 7 continues to rise to the removal position, and the clamping component 38 rises simultaneously to clamp the photovoltaic module; S33, the gripper hydraulic cylinder 81 drives the gripper positioning frame 82 to move, so that the gripper part 85 clamps the aluminum frame. S34, the upper cylinder 84 is pushed out, the gripper hydraulic cylinder 81 is pushed out, the gripper 85 clamps the aluminum frame and moves outward, thereby removing the aluminum frame in the width direction of the photovoltaic module. S35, the gripper 85 moves to the position of the aluminum frame receiving carriage 91, the upper cylinder 84 retracts, the push-out cylinder 88 extends and retracts, pushes the aluminum frame out of the gripper 85 and makes the aluminum frame fall into the aluminum frame receiving carriage 91. S36, the gripper hydraulic cylinder 81 retracts, the lifting mechanism 7 descends, and the photovoltaic module is rotated. Repeat steps S33 to S35 to remove the aluminum frame along the length of the photovoltaic module. S37. After the aluminum frame of the photovoltaic module is removed, the lifting mechanism 7 drives the photovoltaic module to descend and reset.

[0040] In the specific process, when the measuring grating 37 detects that the photovoltaic module has been transmitted to the aluminum frame removal position, the transmission line 32 stops; the electric cylinder and the pneumatic cylinder of the centering module 35 act again to center and clamp the photovoltaic module; the lifting electric cylinder 72 of the lifting mechanism 7 drives the positioning seat 71 to rise to the rotation position, and the rotating slide 73 drives the module to rotate 90° clockwise, so that the short side of the module faces the gripper mechanism 8. S32, the lifting electric cylinder 72 continues to drive the positioning seat 71 to the removal position, the hydraulic cylinder of the clamping component 38 of the transmission mechanism 3 extends, and the photovoltaic module is clamped up and down with the rubber pad of the upper support frame 31. S33, the gripper hydraulic cylinder 81 of the gripper mechanism 8 drives the gripper positioning frame 82 to move inward, and adjusts the spacing of the gripper pieces 85 according to the size of the photovoltaic module, so that the gripper pieces 85 can hold the aluminum frame of the short side of the module. S34, the upper cylinder 84 of the gripper actuator extends, pushing the gripper 85 to further clamp the aluminum frame; then the gripper hydraulic cylinder 81 drives the gripper positioning frame 82 to move outward, removing the aluminum frame of the short side of the photovoltaic module. S35 When the gripper positioning frame 82 moves above the aluminum frame receiving carriage 91, the upper cylinder 84 retracts and the push-out cylinder 88 extends to push the aluminum frame out of the gripper 85, and the frame falls into the aluminum frame receiving carriage 91; the push-out cylinder 88 retracts and the gripper hydraulic cylinder 81 drives the gripper positioning frame 82 to reset. S36, the hydraulic cylinder of the clamping component 38 descends, and the lifting electric cylinder 72 drives the positioning seat 71 to descend to the rotation position; the rotating slide 73 drives the component to rotate 90° clockwise, so that the long side of the component faces the gripper mechanism 8; repeat the actions of S32-S35 to remove the aluminum frame of the long side of the photovoltaic component. S37. After the long side frame is removed, the hydraulic cylinder of the clamping component 38 descends to the lowest position, and the lifting electric cylinder 72 drives the positioning seat 71 to descend to the lowest position, and the photovoltaic module is placed on the transmission line 32; the centering component 35 is reset, and the transmission line 32 is started.

[0041] Understandably, in step S3, the rotation of the lifting mechanism 7 causes the short and long sides of the component to face the gripper mechanism 8 sequentially, achieving orderly removal of the frame from different directions without needing to adjust the gripper position, thus simplifying the operation. The clamping, pulling, and unloading actions of the gripper 85 are continuous, and in conjunction with the ejector cylinder 88, the frame is automatically collected, improving removal efficiency. After the frame is removed, the lifting mechanism 7 drives the component to reset, ensuring that the component is placed stably on the transmission line 32, laying the foundation for subsequent milling processes. Removing the short and long sides of the frame in steps avoids damage caused by uneven force on the component, improving the recycling quality.

[0042] In step S4, the specific process is as follows: the transmission line 32 drives the photovoltaic module to the milling mechanism 6. When the photovoltaic module reaches the milling position, the transmission line 32 stops, and the centering component 35 moves to center and clamp the photovoltaic module. The lifting module 62 of the milling mechanism 6 drives the milling cutter 66 to descend to the set depth. The dual-slider dual-drive module 63 adjusts the position of the milling cutter 66, and the milling cutter drive motor 65 drives the milling cutter 66 to rotate, milling the residual EVA adhesive and backsheet on the surface of the photovoltaic module. After milling is completed, the lifting module 62 drives the milling cutter 66 to rise and reset, and the centering component 35 resets.

[0043] In step S5, the specific process is as follows: the transmission line 32 is started, and the milled photovoltaic module is transferred to the discharge end of the container-type installation body 1 to enter the next recycling process; at this point, the process of removing the junction box and aluminum frame of the photovoltaic module is completed.

These mechanisms work together to achieve fully automated operation of removing photovoltaic module junction boxes and aluminum frames without manual intervention, greatly reducing labor intensity and improving production efficiency.

[0045] High dismantling efficiency: Each mechanism adopts a highly efficient driving method and working principle. For example, the junction box removal mechanism 4 uses a cylinder to drive the scraper 48 to quickly remove the junction box, the corner piece cutting mechanism 5 uses an angle grinder 55 to cut the corner pieces at high speed, the gripper mechanism 8 quickly removes the aluminum frame through the coordinated action of a cylinder and a hydraulic cylinder, and the milling cutter mechanism 6 quickly mills the residual adhesive layer and back plate through a high-speed rotating milling cutter 66. The entire dismantling process is continuous and efficient, which can meet the needs of large-scale industrial recycling production.

[0046] High-quality dismantling: The device is equipped with multiple positioning and guiding mechanisms, such as the centering component 35, measuring grating 37, laser sensor, upper guide plate 86, and lower guide plate 87, which ensure accurate positioning of the photovoltaic modules during dismantling and precise operation of each dismantling mechanism. This avoids damage to other components of the photovoltaic modules, guarantees the quality of the recovered components, and improves resource recycling rates. Friendly working environment: The containerized installation body 1 is equipped with a ventilation system that promptly sucks in and treats harmful substances such as dust and debris generated during dismantling, creating a negative pressure environment inside the device. This effectively improves the working environment, reduces harm to the health of operators, and minimizes environmental pollution.

[0047] High safety: The device adopts fully automated operation, and operators do not need to directly contact the demolition work area, avoiding safety accidents that may occur during manual operation.

[0048] High degree of automation: This device integrates multiple automated mechanisms, including transmission mechanism 3, junction box removal mechanism 4, corner piece cutting mechanism 5, milling cutter mechanism 6, lifting mechanism 7, gripper mechanism 8, and material receiving mechanism 9. These mechanisms work together to achieve fully automated operation of removing photovoltaic module junction boxes and aluminum frames without manual intervention, greatly reducing labor intensity and improving production efficiency.
