[0010] Furthermore, an elastic pad layer is uniformly provided at the bottom of the upper top plate, and multiple force sensors are embedded in the elastic pad layer at the bottom of the upper top plate. The multiple force sensors are evenly distributed and installed at the four corners and the center of the upper top plate.

[0013] Furthermore, an angle sensor and a position sensor are installed at the bottom of the rotating platform, and the same clamping force sensor is installed at the bottom of the top plate and on the output shaft of the clamping cylinder. A vacuum pressure sensor is installed on the rotating pallet. A fully enclosed protective cover is installed on the base, and an emergency stop button is installed on the outside of the fully enclosed protective cover. A single-sided machine of the photovoltaic module frame double-sided synchronous removal and recycling device is installed on both sides of the gantry, and the single-sided machine of the photovoltaic module frame double-sided synchronous removal and recycling device is fixedly installed on the first slide. A control cabinet and a frame shaping and recycling assembly are installed on one side of the base, and the control cabinet is located on one side of the gantry.

An abnormal alarm device is installed on the top of the control cabinet and is electrically connected to the control cabinet. The frame shaping and recycling assembly includes a clamping and shaping unit, a diversion guide groove, a frame pusher actuator, and a recycling conveying unit to realize the shaping and centralized recycling of the frame.

[0014] This invention also proposes a method for synchronous double-sided frame removal and recycling of photovoltaic modules, comprising the following steps: starting the control cabinet, initializing and debugging the device, setting the working parameters of each component, including the lifting height of the lifting cylinder, the holding force threshold of the top plate, the rotation speed and feed speed of the adhesive removal knife, the advancing speed of the wedge clamping knife, and the rotation angle of the rotating platform (90°); checking the working status of each sensor, servo motor, and cylinder, ensuring that the fully enclosed protective cover is closed, the access control interlock switch is normal, and the emergency stop button is in standby mode; adjusting the position of the double-sided adhesive cutting mechanism and the wedge clamping peeling mechanism to ensure precise alignment with the height of the module frame; checking the heating effect of the hot air nozzle to ensure that the adhesive layer heating and softening temperature meets the standard, and placing the waste photovoltaic modules in... On the conveyor platform, the conveyor rotates at a constant speed, smoothly transporting the components to the rotating pallet of the rotating lifting platform. The rotating pallet, equipped with an anti-slip structure or vacuum adsorption (if configured to fix the components), an elastic buffer layer, and edge protection pads, protects the component glass. Four lifting cylinders are activated, their piston rods extending synchronously to lift the rotating pallet and components together to the preset frame removal height. This ensures the component frame is aligned with the working height of the double-sided glue-cutting mechanism and the wedge-shaped clamping and peeling mechanism. After lifting, the lifting cylinders remain extended, achieving the load-bearing positioning of the component. Once the component reaches the frame removal height, the reference positioning block on the rotating platform provides directional reference positioning for the component. The lateral clamping unit is activated, horizontally advancing and clamping the component edges, limiting displacement within the component plane. The drive components of the upper top plate, including cylinders / electric cylinders / servo presses, lower the upper top plate at a uniform speed. The elastic pad at the bottom adheres to the surface of the component laminate. Force sensors monitor the holding force in real time. When the holding force reaches a set threshold, the drive components stop, maintaining the holding state of the upper top plate to prevent slippage or damage to the component during glue cutting and peeling. The glue removal servo motor and hot air nozzle are activated. The glue removal servo motor drives the glue removal blade to rotate at high speed through a coupling, and the hot air nozzle heats and softens the glue layer between the component's opposite side frames and the laminate. The slide servo motor is activated, driving the lead screw module to rotate, causing the first slide and the double-sided glue cutting mechanism to feed uniformly along the length of the frame. The glue removal blade precisely cuts the softened glue layer, with the cutting path adhering to the edge. In the area where the frame and the laminate meet, the adhesive layer is thoroughly cut without any residue. During the cutting process, based on the tool load current / resistance feedback, the control system differentially fine-tunes the feed speed of the adhesive removal blades on both sides to ensure consistent cutting on both sides. After cutting, the adhesive removal servo motor and hot air nozzle stop working, and the slide servo motor drives the first slide to reset the double-sided adhesive cutting mechanism. After cutting, the wedge clamping and peeling mechanism is activated, and the clamping cylinder drives the wedge clamping blade to descend vertically, clamping the frame on both sides of the assembly. The drive component of the second slide is activated, which drives the wedge clamping blade to advance at a constant speed along the length of the frame. The progressive wedge end of the wedge clamping blade inserts into the gap between the frame and the laminate, gradually widening the peeling gap and achieving separation of the frame and the laminate.During the pushing process, the follow-up clamping component moves synchronously with the wedge-shaped clamping cutter, applying a continuous clamping reaction force to the edge of the module laminate to suppress module warping. The control system monitors the pushing force and motor current of the wedge-shaped clamping cutters on both sides in real time. If the resistance on one side is abnormal, such as a sudden increase in resistance, strategies such as speed reduction, retraction, secondary cutting of adhesive, or enhanced softening are immediately implemented to avoid unilateral "hard pressing" that could lead to module breakage. After peeling is completed, the clamping cylinder resets, the wedge-shaped clamping cutter releases the frame, the second slide moves the wedge-shaped clamping cutter back to its original position, and after the frame is peeled off, the push-frame actuator is activated to push the peeled sides of the frame back to their original positions. The frame strip is pushed into the clamping and shaping unit; the clamping and shaping unit uses adjustable-pitch rollers or pressure plates to limit, guide, and straighten the frame strip, correcting any bending or deformation that occurs during the peeling process; after shaping, the frame pusher is restarted, pushing the shaped frame strip into the independent diversion and recycling conveying units on the left and right sides of the corresponding channel. The recycling conveying units operate at a constant speed, transporting the frame strip to the recycling bin or packaging unit, completing the centralized recycling of the frame strips; during the recycling process, the recycling bins can be sorted and stored according to the size and condition of the frame strips for easy reuse later. Component 1 After the side frames are removed and recycled, the drive unit of the top plate is activated, the top plate rises and resets, and the lateral clamping unit releases the assembly; the locking unit releases the rotating platform, and the first rotating platform servo motor is activated, driving the rotating platform and assembly to rotate synchronously by 90° through the gear cross steering box. The angle sensor monitors the rotation angle in real time. When the rotation reaches the preset angle of 90°, the rotating platform servo motor stops working, and the locking unit locks the rotating platform again; the other two sides of the assembly's frame are then simultaneously cut, peeled, shaped, and recycled, completing the removal and recycling of all four sides of the assembly's frame. After all four frame components are removed and recycled, the lateral clamping unit releases, the piston rod of the lifting cylinder retracts, and the rotating pallet and the glass and laminate components after frame removal descend to their initial positions. The components after frame removal are then removed from the rotating pallet, completing the unloading operation. After unloading, the equipment reset program is initiated, and the top plates of each component, the wedge-shaped clamping and peeling mechanism, the double-sided glue-cutting mechanism, the rotating platform, etc., are all reset to their initial states, awaiting the next set of component frame removal and recycling operations. If the equipment is not used for an extended period, the control cabinet power is turned off, debris in the work area is cleaned, and all moving parts are lubricated and maintained.

[0015] In summary, this application includes at least one of the following beneficial technical effects: 1. It can simultaneously remove the frame from both sides of the existing photovoltaic module frame, which greatly improves the frame removal efficiency compared to the existing single-side sequential frame removal mode. By rotating the platform 90° to precisely switch sides, the frame of all four sides can be removed in two steps, simplifying the operation process, reducing manual intervention, and adapting to the needs of large-scale recycling. 2. By achieving coordinated control of rubber cutting and peeling, the hot air nozzle heats and softens the rubber layer, which is then precisely cut by the rubber removal knife. The wedge-shaped clamping blade peels off gradually, and the follow-up pressure protection reduces frame deformation and component damage. At the same time, the emergency adjustment strategy based on resistance feedback further improves the safety and stability of the operation. 3. It can achieve integrated shaping and recycling of the frame. After the frame is stripped, it is shaped to meet the standards of straightness and regularity, which facilitates secondary use and improves the resource recycling rate. The independent left and right diversion recycling design avoids cross-interference of the frame and ensures a smooth recycling process. 4. It can coordinate the operation of various components through the control cabinet, and various sensors monitor the operation status in real time, enabling precise parameter adjustment and emergency handling of abnormalities, thus reducing the intensity of manual labor; the comprehensive safety protection mechanism (fully enclosed protective cover, access control interlock, emergency stop button, abnormal alarm) can effectively protect the personal safety of operators and the safety of equipment and property.

The frame shaping and recycling assembly includes a clamping and shaping unit, a diversion guide groove, a frame pusher actuator, and a recycling conveying unit to achieve frame shaping and centralized recycling.

[0029] The implementation steps of a method for synchronously dismantling and recycling photovoltaic module frames on both sides according to an embodiment of this application are as follows: First, the equipment is initialized and debugged, and various working parameters are set to ensure that all components work normally; the waste photovoltaic modules are transported to the rotating pallet 101 through the conveyor platform 9, and the lifting cylinder 105 lifts the modules to the dismantling height; the upper top plate 8 lowers to hold the modules, and the lateral clamping unit fixes the modules to achieve precise positioning; the bilateral glue cutting mechanism is started, the hot air nozzle softens the glue layer, and the glue removal knife 4 simultaneously cuts the glue layer on both sides of the module frame; after the glue cutting is completed, the wedge clamping and peeling mechanism 1 clamps the frame and peels it off gradually, and the follow-up holding component protects the module; peeling The frame is then shaped, sorted, and transported to the recycling unit by the shaping and recycling component. Subsequently, the rotating platform 2 rotates the component 90°, repeating the above steps of cutting, peeling, and recycling to complete the removal of the four-sided frame of the component. Finally, the material is unloaded, the equipment is reset, and the next set of operations begins. The entire process is highly automated, with simultaneous bilateral operations improving efficiency. Precise positioning and protection mechanisms reduce the risk of damage to the component and frame, achieving efficient and high-quality frame recycling. The control cabinet is started to initialize and debug the device, setting the working parameters of each component, including the lifting height of the lifting cylinder 105, the holding force threshold of the upper plate 8, and the rotation speed and feed of the adhesive removal knife 4. The speed, the advance speed of the wedge clamping cutter 13, and the rotation angle of the rotating platform 2 (90°) are checked; the working status of each sensor, servo motor, and cylinder is checked to ensure that the fully enclosed protective cover is closed, the access control interlock switch is normal, and the emergency stop button is in standby mode; the positions of the double-sided glue cutting mechanism and the wedge clamping peeling mechanism 1 are adjusted to ensure precise alignment with the height of the component frame; the heating effect of the hot air nozzle is checked to ensure that the glue layer heating and softening temperature meets the standard; the waste photovoltaic modules are placed on the conveyor platform 9, which rotates at a uniform speed to smoothly transport the modules to the rotating pallet 101 of the rotating lifting platform 10; the rotating pallet 101 uses an anti-slip structure If a fixed component is configured for vacuum adsorption, an elastic buffer layer and an edge protection pad protect the component glass. Four lifting cylinders 105 are activated, and the piston rods extend synchronously to lift the rotating pallet 101 and the component together to the preset frame removal height. This ensures that the component frame is aligned with the working height of the double-sided glue cutting mechanism and the wedge clamping and peeling mechanism 1. After lifting, the lifting cylinders 105 remain extended to achieve the load-bearing positioning of the component. After the component is raised to the frame removal height, the reference positioning block on the rotating platform 2 performs reference positioning of the component in the X / Y direction. The lateral clamping unit is activated to horizontally advance and clamp the edge of the component, limiting the displacement within the component plane.The drive unit of the upper top plate 8, consisting of a pneumatic / electric / servo press, is activated. The upper top plate 8 descends at a constant speed, and the elastic pad at the bottom adheres to the surface of the component laminate. A force sensor monitors the holding force in real time. When the holding force reaches a set threshold, the drive unit stops, maintaining the holding state of the upper top plate 8 to prevent slippage or damage to the component during the cutting and peeling process. The glue removal servo motor 3 and the hot air nozzle are activated. The glue removal servo motor 3 drives the glue removal blade 4 to rotate at high speed through the coupling 31. The hot air nozzle heats and softens the glue layer between the component's opposite side frames and the laminate. The slide servo motor 7 is activated, driving the lead screw module 6 to rotate, causing the first slide 61 and the double-sided glue cutting mechanism to feed at a constant speed along the length of the frame. The glue removal blade 4 makes precise cuts. After softening, the cutting path of the adhesive layer conforms to the bonding area between the frame and the laminate, ensuring thorough cutting without residue. During the cutting process, based on the tool load current / resistance feedback, the control system differentially fine-tunes the feed speed of the two adhesive removal blades 4 to ensure consistent cutting on both sides. After cutting, the adhesive removal servo motor 3 and the hot air nozzle stop working, and the slide servo motor 7 drives the first slide 61 to reset the double-sided adhesive cutting mechanism. After cutting, the wedge clamping and peeling mechanism 1 is activated, and the clamping cylinder 11 drives the wedge clamping blade 13 to descend vertically, clamping the frame on both sides of the assembly. The drive component of the second slide 12 is activated, driving the wedge clamping blade 13 to advance at a constant speed along the length of the frame, and the progressive wedge end of the wedge clamping blade 13 inserts into the frame. The gap between the frame and the laminate is gradually widened to achieve separation of the frame from the laminate. During the pushing process, the follower holding member moves synchronously with the wedge clamping cutter 13, applying a continuous holding reaction force to the edge of the component laminate to suppress component warping. The control system monitors the pushing force and motor current of the wedge clamping cutters 13 on both sides in real time. If the resistance on one side is abnormal, such as a sudden increase in resistance, strategies such as deceleration, retraction, secondary cutting of adhesive, or enhanced softening are immediately implemented to avoid unilateral "hard pressing" that could cause component breakage. After peeling is completed, the clamping cylinder 11 is reset, the wedge clamping cutter 13 releases the frame, the second slide 12 drives the wedge clamping cutter 13 to reset, and after the frame is peeled off, the push frame actuator is activated to push the peeled frame strips on both sides into the clamping and shaping unit. The clamping and shaping unit uses adjustable-pitch rollers or pressure plates to limit and guide the frame strips and straighten them, correcting the bending and deformation caused by the frame strips during the peeling process. After the shaping is completed, the frame pusher is started again, pushing the shaped frame strips into the corresponding channels of the diversion guide groove for independent diversion on both sides. The frame strips slide down the diversion guide groove to the recycling conveying unit, which operates at a constant speed to transport the frame strips to the recycling box or packaging unit, completing the centralized recycling of the frame. During the recycling process, the recycling box can be classified and stored according to the size and condition of the frame for easy secondary use. After the two frames on one side of the component are removed and recycled, the drive component of the top plate 8 is started, the top plate 8 rises and resets, and the side clamping unit releases the component.The locking unit releases the rotating platform 2, activating the first rotating platform servo motor 21. This motor drives the rotating platform 2 and the component to rotate synchronously by 90° via the gear cross steering box 102. An angle sensor monitors the rotation angle in real time. When the preset angle of 90° is reached, the rotating platform servo motor stops, and the locking unit locks the rotating platform 2 again. The other two sides of the component's frame are then simultaneously cut, peeled, shaped, and recycled, completing the removal and recycling of all four sides of the component's frame. After all four sides of the component's frame are removed and recycled, the lateral clamping unit releases, and the support... The piston rod of cylinder 105 retracts, causing the rotating pallet 101 and the glass and laminate components after frame removal to descend to their initial positions. The components after frame removal are then removed from the rotating pallet 101, completing the unloading operation. After unloading, the equipment reset program is initiated, and the top plate 8, wedge-shaped clamping and peeling mechanism 1, double-sided glue-cutting mechanism, rotating platform 2, etc., are all reset to their initial states, awaiting the next set of components to be disassembled and recycled. If the equipment is not used for an extended period, the control cabinet power is turned off, debris in the work area is cleaned, and all moving parts are lubricated and maintained.

[0030] Example 2 The difference between this embodiment and Embodiment 1 is that: a frame shaping and recycling assembly is fixedly installed on one side of the discharge end of the rotating platform 2. The frame shaping and recycling assembly includes a clamping and shaping unit, a frame pusher actuator, a diversion guide groove, and a recycling conveying unit. The clamping and shaping unit is horizontally installed on the base, with the feed end aligned with the edge of the rotating platform 2. The frame pusher actuator is driven by a small linear cylinder, with the cylinder body fixed to one side of the clamping and shaping unit. The output shaft of the frame pusher actuator faces the diversion guide groove. The diversion guide groove is arranged at an inclination (30°) and is divided into two independent channels, left and right, with the discharge end aligned with the recycling conveying unit. The recycling conveying unit uses a belt conveyor, which is horizontally installed below the diversion guide groove, with the discharge end facing the recycling box, ensuring that the frame can be smoothly shaped, diverted, and recycled after peeling, thus completing the process.

[0031] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
