[0002] With the development of the photovoltaic industry, the output of photovoltaic panels is also increasing year by year. However, photovoltaic panels have a service life. After reaching the end of their service life, they need to be removed, recycled and replaced. A junction box is installed on the photovoltaic panel to bring out the internal circuit of the photovoltaic panel to facilitate the connection of the power output line. After recycling, it needs to be separated from the photovoltaic panel. However, most of the junction boxes of retired photovoltaic panels at present need to be removed manually, which cannot form a continuous mechanical operation and has low efficiency.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] See Figures 1-4 As shown, it includes a frame-shaped base 1. On the top of the base 1, there are linear slide rails 1 and 5 on the left and right ends respectively, and linear slide rails 23 on the front and rear ends respectively. A disassembly mechanism for removing the junction box on the photovoltaic panel is provided above the linear slide rail 1 and two sets of conveying mechanisms for feeding the photovoltaic panel in and out are provided on the linear slide rail 1. On the base 1, there is a stop mechanism 27 at the rear end for blocking the photovoltaic panel and positioning it. The disassembly mechanism includes a gantry structure consisting of a movable crossbeam 11 and two support legs 6. The movable crossbeam 11 has multiple parallel linear guide rails 9, each with a fixed seat mounted on its slider. One end of the movable crossbeam 11 is also equipped with a precision reducer 10 driven by a servo motor. The front end of the precision reducer 10 is connected to a ball screw 14 via a coupling 12. The ball screw 14 is rotatably mounted on the movable crossbeam 11 via a screw support 13. The ball screw 14 drives the connecting... The fixed seat is connected to the fixed seat and the fixed seat is moved by the rotation of the ball screw 14. Multiple linear slide rails 17 are vertically arranged in front of the fixed seat. A connecting body 18 is slidably installed on the slider of the linear slide rail 17. A lifting reducer 15 is arranged downward on the fixed seat. A screw is connected to the lower end of the lifting reducer 15. The screw is connected to the connecting body 18 by a thread drive. A lifting motor 16 is connected to the top of the lifting reducer 15. A cutting knife group 19 for cutting off the junction box is connected to the bottom end of the connecting body 18. The cutter assembly 19 includes a housing 37 body. Multiple sets of guide post and guide sleeve assemblies 31 are arranged horizontally inside the housing 37 body, and two sets of slide blocks 32 are slidably installed. Cylinders 20 are respectively provided at both ends of the housing 37 body. The front ends of the cylinders 20 are connected to the slide blocks 32. The bottom end of the slide block 32 is connected to the cutter 33 inward. The two form a 90° angle between them, and the cutters 33 of the two slide blocks 32 are arranged opposite to each other. Both ends of the support leg 6 slide on the linear slide rail 5 via sliders. On the base 1, a precision rack 3 is provided on the side of the linear slide rail 5. A precision reducer 4 driven by a servo motor is installed on the bottom side of the support leg 6. A ground helical gear 2 is provided on the output shaft of the precision reducer 4, and the ground helical gear 2 meshes with the precision rack 3.

[0019] The two support legs 6 are driven by a precision reducer 4 driven by a motor at the bottom. Through the meshing of the grinding helical gear 2 and the precision rack 3, the support legs 6 and the upper structure are driven to slide back and forth above the linear slide rail 5. Similarly, the motor on the moving crossbeam 11 drives a precision reducer 10, which drives the fixed seat to slide left and right through the ball screw 14. Therefore, the cutter assembly 19 can be adjusted in position above the base 1, both forward and backward and left and right, to reach any position, so as to ensure that the junction box on the photovoltaic panel can be cut off. The lifting motor 16 drives the connecting body 18 to move vertically, which in turn drives the cutter assembly 19 to move up and down, so that the cutter 33 can move to the root position of the junction box. The two cylinders 20 can then drive the cutter 33 to move inward, cutting into the bottom of the junction box and separating it from the photovoltaic panel below. The cut junction box will be above the cutter 33. After cutting, the junction box is clamped in the cutter assembly 19 until the cutter 33 opens outward, at which point the junction box can fall.

[0020] See Figures 1-4As shown, the operation and stopping mechanism 27 includes a linear slide rail 36 installed in the vertical direction. The top of the slider of the linear slide rail 36 is connected to an "L"-shaped limit block 34. The linear slide rail 36 is provided with a lead screw for driving the slider to move. The bottom of the base 1 is provided with a control motor 29 and a limit reducer 30 for driving the lead screw.

[0021] The control motor 29 drives the limit reducer 30, which in turn drives the slider to slide vertically on the linear slide rail 36 via the lead screw, thereby controlling the limit block 34 to move up and down. When it rises, it can block the front of the photovoltaic panel, limiting and positioning the photovoltaic panel to prevent it from sliding forward. When it falls, the limit can be released, and the photovoltaic panel can be sent forward.

[0022] See Figures 1-4 As shown, the conveying mechanism includes conveying beam legs 22 respectively mounted on two linear slide rails 23, with a conveying beam 21 connecting the two to form a "gate" shaped structure. The conveying beam 21 is equipped with a conveying sprocket assembly 28. A conveying motor 26 and a conveying reducer 25 are installed at one end of the conveying beam 21. The output shaft of the conveying reducer 25 is connected to the conveying sprocket assembly 28 via a coupling 24. The base 1 has fine-tuning handwheels 7 on both sides, and each fine-tuning handwheel 7 is connected to a fine-tuning screw 8. The two sets of fine-tuning screws 8 are respectively connected to the two conveying beams 21 by thread drive.

[0023] The left and right positions of each set of conveying beams 21 are adjusted using the fine-tuning handwheel 7 and the fine-tuning screw 8. The two conveying beams 21 are adjusted independently and do not affect each other. Therefore, on the one hand, they can be adjusted to accommodate the conveying of photovoltaic panels of different widths, and on the other hand, the overall conveying position of the photovoltaic panels can be adjusted, such as conveying them to the right or left in the equipment, which provides high flexibility.

[0024] See Figures 1-6 As shown, the outer side of the above structure is also provided with a housing 37. The housing 37 is provided with control buttons 38 for adjusting the status of the equipment and a display screen 39 for displaying the working status. A vision recognition probe 40 is provided at the top inside the housing 37. Multiple controllers 35 are provided on the housing 37 for driving vision recognition, machine action and power supply. The vision recognition probe 40 is used to identify the position of the junction box after the photovoltaic panel is positioned. Then, the host computer controls the cutter group 19 to the corresponding position to perform the box cutting operation based on the position data. The selection of the vision recognition probe 40 and the recognition processing algorithm are all existing technologies. After 500-1000 data trainings, it is sufficient to meet the requirements of recognition speed and accuracy. Therefore, it will not be described in detail here.

[0025] During operation, the photovoltaic panel is fed in, the limiting block 34 rises, and the conveyor sprocket assembly 28 moves the photovoltaic panel forward until it hits the limiting block 34. The conveyor sprocket assembly 28 then stops, the vision recognition probe 40 acquires the junction box position, and the host computer sends a command. The cutter assembly 19 moves above the junction box, the cutter 33 opens to both sides and descends to the sides of the junction box base, then cuts inward to cut off the panel and pulls it upward to be placed into the recycling equipment or container. The limiting block 34 then descends, and the conveyor sprocket assembly 28 moves the photovoltaic panel forward, completing the processing of one photovoltaic panel. The process then continues with the processing of the next photovoltaic panel, performing continuous operation.

[0026] The installation, connection, or setting methods of the components not detailed above are all common mechanical methods, and the specific structure, model, and coefficient indicators of all their components are their own technologies. As long as they can achieve their beneficial effects, they can be implemented, so they will not be elaborated further.

[0027] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of the invention and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of the invention should be included within the protection scope of the invention. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
