Description

Technical Field

[0001] This application relates to the field of photovoltaic module recycling technology, and more specifically, to a fully automatic punching and cutting machine for waste photovoltaic modules. Background Technology

[0002] After a certain number of years of use, the performance of photovoltaic panels deteriorates significantly, necessitating dismantling and recycling to create economic value and avoid resource waste. The first step in recycling is removing the aluminum alloy frame, but the frame is firmly connected to the photovoltaic panel, making manual dismantling extremely laborious and inefficient. Summary of the Invention

[0003] To overcome the above deficiencies, this application provides a fully automatic punching and cutting machine for waste photovoltaic modules, which aims to improve the problems mentioned in the background art.

[0004] This application provides a fully automatic punching and cutting machine for waste photovoltaic modules, including a support assembly and a punching and cutting assembly. The support assembly includes a frame and a transfer component, the transfer component being disposed on the frame. The punching and cutting assembly includes four edge-cutting components, which are respectively disposed around the perimeter of the frame, and each edge-cutting component is provided with a control frame component.

[0005] In one specific implementation, the transfer component includes a linear module A, which is disposed on the frame and has two lifting cylinders.

[0006] In the above implementation process, the linear module A includes two linear slide rails driven by servo motors, with crossbars installed on the two slide rails, and a lifting cylinder installed in the middle of the crossbars to support the photovoltaic panel.

[0007] In one specific implementation, a push plate is fixedly connected to the telescopic end of one of the lifting cylinders, and a clamping plate is fixedly connected to the telescopic end of the other lifting cylinder.

[0008] In the above process, a rotating roller is installed at the feed end of the frame to facilitate the entry of the photovoltaic module panel from the front machine into the machine. At the same time, the lower clamping plate rises and stops when the photovoltaic module reaches the detection sensor at the front of the clamping plate. Then the clamping plate descends and moves laterally, then rises again, positioning the frame of the photovoltaic module above the clamping plate, and then pulls the photovoltaic module panel forward. Subsequently, the clamping plate descends until the rear edge of the photovoltaic module panel is positioned at the rear cutting edge, where it is first cut. Then, the pusher plate pushes the photovoltaic module panel to the front cutting edge, and the three cutting edges on the left, right, and front sides begin cutting simultaneously. After cutting is completed, the pusher plate pushes the photovoltaic panel away from the frame.

[0009] In one specific implementation, a linear module B is provided on the frame, one of the trimming elements is provided on the linear module B, and the remaining trimming elements are provided on the frame.

[0010] In the above implementation process, the linear module B includes two guide rails and a screw. The rotation of the screw drives the corresponding bracket to translate along the two guide rails, so that the cut edge on one side moves inward to adapt to photovoltaic module panels of different widths.

[0011] In one specific implementation, the cutting element includes a bracket and a hydraulic cylinder. The hydraulic cylinder is mounted on the bracket, and a blade holder is mounted on the telescopic end of the hydraulic cylinder. A blade is mounted on the blade holder, and a support plate corresponding to the blade is also mounted on the bracket.

[0012] In the above implementation process, a guide structure is set on the tool holder to improve the stability of the tool holder. Multiple blades are installed on the tool holder to form a long strip blade, which is easy to replace. The frame of the photovoltaic module is located on the support plate. Two hydraulic cylinders push the blade down to punch the connection between the frame and the photovoltaic panel, thereby removing the frame with high efficiency.

[0013] In one specific implementation, a pressure block is elastically connected to the tool holder.

[0014] In the above implementation process, the tool holder is equipped with a spring and a guide rod. One end of the guide rod is slidably connected to the tool holder, and the other end of the guide rod is fixedly connected to the pressure block. The two ends of the spring are respectively pressed against the pressure block and the tool holder. During the downward movement of the blade, the pressure block contacts the frame first and presses the frame down, which is beneficial to the stability of the frame during cutting and when the blade is pulled out.

[0015] In one specific implementation, the control frame includes a vertical cylinder and a horizontal cylinder. The vertical cylinder is mounted on the bracket, and the horizontal cylinder is mounted on the telescopic end of the vertical cylinder. A push-pull plate is elastically connected to the telescopic end of the horizontal cylinder.

[0016] In the above process, the vertical cylinder and the horizontal cylinder work together to move the push-pull plate. A guide rod is fixedly connected to the push-pull plate, and the other end of the guide rod is slidably connected to the telescopic end of the horizontal cylinder. A spring is provided on the guide rod to achieve the elastic connection of the push-pull plate. In addition, a gap is provided at the bottom of the bracket to allow the frame to fall. Specifically, when the photovoltaic module panel is close to the push-pull plate, both the vertical cylinder and the horizontal cylinder push out, the frame of the photovoltaic module panel abuts against the push-pull plate, and causes the push-pull plate to retract backward. Then, the pressure block presses down on the frame and begins cutting. The frame is kept in place by the push-pull plate and the pressure block. Then the push-pull plate moves backward and rises, the pressure block then disengages from the frame, and finally the push-pull plate moves forward, descends, and moves backward, pulling the frame back into the gap on the bracket and letting it fall out.

[0017] In one specific implementation, the cutting edge members on the left and right sides are further provided with a shift frame member. The shift frame member includes a drive cylinder and a gear. The drive cylinder is mounted on the bracket. A rack is provided on the telescopic end of the drive cylinder to mesh with the gear. A shift lever is fixedly connected to the gear.

[0018] In the above implementation process, since one of the side brackets will enter between the front and rear brackets under the drive of the linear module B, when the frame is cut off, it will interfere with the edge of the bracket. At this time, the drive cylinder drives the rack to move, drives the gear to rotate, and then drives the lever to rotate, pushing the frame back a small distance to avoid the edge of the bracket. Then the push-pull plate can smoothly pull the frame back to the gap and fall down.

[0019] In one specific implementation, a lifting cylinder is provided at the front end of the frame.

[0020] In the above process, after the three frames are cut off together, the rear part of the photovoltaic panel will fall onto the transfer component, while the front part of the photovoltaic panel will fall onto the lifting cylinder. At this time, the lifting cylinder will lift the photovoltaic panel above the height of the support plate so that the push plate can smoothly push the photovoltaic panel away from the frame.

[0021] In one specific implementation, the frame is surrounded by a panel, a controller is mounted on the panel, and an oil supply mechanism is mounted on the upper end of the frame.

[0022] In the above implementation process, the controller is used to control the equipment to operate according to the set program, and the oil supply mechanism provides hydraulic oil to the hydraulic cylinder.

[0023] Compared with the prior art, the beneficial effects of this application are: the support component uses the transfer component to help the photovoltaic module panel move and align the four cutting edge pieces within the frame. After the cutting edge pieces are cut, the photovoltaic panel can be pushed out using the transfer component, which effectively improves the frame disassembly efficiency. Attached Figure Description

Detailed Implementation

[0031] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0032] Please see Figures 1-5 This application provides a fully automatic punching and cutting machine for waste photovoltaic modules, including a support component 100 and a punching component 200. The support component 100 includes a frame 110 and a transfer component 120, which is disposed on the frame 110. The punching component 200 includes four edge-cutting components 210, which are respectively disposed around the perimeter of the frame 110. Each edge-cutting component 210 is provided with a frame control component 220. The support component 100 utilizes the transfer component 120 to assist the photovoltaic module panel in moving and aligning with the four edge-cutting components 210 within the frame 110. After the edge-cutting components 210 have finished cutting, the transfer component 120 is used to push the photovoltaic panel out, effectively improving the frame disassembly efficiency.

[0033] Please see Figures 1-3The transfer unit 120 includes a linear module A121, which is mounted on the frame 110. Two lifting cylinders 122 are mounted on the linear module A121. The linear module A121 includes two linear slide rails driven by a servo motor. A crossbar is mounted on each of the two slide rails, and a lifting cylinder 122 is mounted in the middle of the crossbar to support the photovoltaic panel.

[0034] Please see Figures 2-3 One of the lifting cylinders 122 has a push plate 123 fixedly connected to its telescopic end, and the other lifting cylinder 122 has a clamping plate 124 fixedly connected to its telescopic end. A rotating roller is provided at the tail end of the frame 110 to help the photovoltaic module panels enter the machine from the front machine. At the same time, the lower clamping plate 124 is raised and stops after the photovoltaic module reaches the detection sensor at the front of the clamping plate. Then, the clamping plate 124 descends and moves horizontally, then rises again, positioning the frame of the photovoltaic module above the clamping plate 124. The photovoltaic module is then pulled forward. The clamping plate 124 descends until the rear edge of the photovoltaic module is positioned at the cutting edge 210. Cutting is performed first, and then the push plate 123 pushes the photovoltaic module to the cutting edge 210 in front. The three cutting edges 210 on the left, right, and front sides start cutting simultaneously. After cutting is completed, the push plate 123 pushes the photovoltaic panel away from the frame 110. The transfer component 120 realizes a complete set of actions for the panel to enter, position, and exit smoothly. It has the advantages of compact structure, strong adaptability, and high degree of automation.

[0035] Please see Figures 2-3 A linear module B130 is mounted on the frame 110, with one slit piece 210 mounted on the linear module B130 and the remaining slit pieces 210 mounted on the frame 110. The linear module B130 includes two guide rails and a screw. The rotation of the screw drives the corresponding bracket 211 to translate along the two guide rails, causing one side of the slit piece 210 to move inward to accommodate photovoltaic modules of different widths. This design, with three sides fixed and one side movable, achieves compatibility with larger-sized modules in a minimal space, avoiding the disadvantages of complex structure and high manufacturing difficulty, and features a simple structure and novel design.

[0036] Please see Figures 2-4The edge-cutting component 210 includes a bracket 211 and a hydraulic cylinder 212. The hydraulic cylinder 212 is mounted on the bracket 211, and a blade holder 213 is mounted on the telescopic end of the hydraulic cylinder 212. A blade 214 is mounted on the blade holder 213, and a support plate 215 corresponding to the blade 214 is also mounted on the bracket 211. A guide structure is provided on the blade holder 213 to improve its stability. Multiple blades 214 are mounted on the blade holder 213 to form a long, narrow blade for easy replacement. The frame of the photovoltaic module panel is located on the support plate 215. Two hydraulic cylinders 212 push the blade 214 downwards to cut the connection between the frame and the photovoltaic panel, thereby removing the frame. This method is highly efficient. In this embodiment, a structure composed of multiple blades 214 with arc-shaped cutting edges is used, which facilitates the splicing of different lengths. When a blade 214 is damaged, it is also easy to replace it individually, improving maintainability.

[0037] Please see Figure 4 A pressure block 216 is elastically connected to the blade holder 213. A spring and a guide rod are provided on the blade holder 213. One end of the guide rod is slidably connected to the blade holder 213, and the other end is fixedly connected to the pressure block 216. Both ends of the spring are pressed against the pressure block 216 and the blade holder 213 respectively. During the downward movement of the blade 214, the pressure block 216 contacts the frame first and presses the frame down, which is beneficial to the stability of the frame during cutting and blade removal, avoiding the photovoltaic module panel from deviating. It can also prevent the photovoltaic module panel from bending or warping after cutting, and has the advantages of good error prevention performance and high stability.

[0038] Please see Figures 3-4 The frame control component 220 includes a vertical cylinder 221 and a horizontal cylinder 222. The vertical cylinder 221 is mounted on the bracket 211, and the horizontal cylinder 222 is mounted on the telescopic end of the vertical cylinder 221. A push-pull plate 223 is elastically connected to the telescopic end of the horizontal cylinder 222. The vertical cylinder 221 and the horizontal cylinder 222 work together to move the push-pull plate 223. A guide rod is fixedly connected to the push-pull plate 223, and the other end of the guide rod is slidably connected to the telescopic end of the horizontal cylinder 222. A spring is provided on the guide rod to achieve the elastic connection of the push-pull plate 223. In addition, a gap is provided at the lower part of the bracket 211 to allow the frame to fall. The frame control component 220 is used to realize the actions of pushing, pulling, and lowering the frame. Specifically, when the photovoltaic module panel approaches the push-pull plate 223, the vertical cylinder 221... Both the horizontal cylinder 222 and the horizontal cylinder 222 are pushed out, and the frame of the photovoltaic module panel is pressed against the push-pull plate 223, causing the push-pull plate 223 to retract backward, making a pushing action. Then the pressure block 216 presses down on the frame and begins to cut. The frame is kept in place by the push-pull plate 223 and the pressure block 216. Then the push-pull plate 223 moves backward and rises, and the pressure block 216 then disengages from the frame. Finally, the push-pull plate 223 moves forward, descends, and moves backward, making a pulling action, pulling the frame back into the gap on the bracket 211 and letting it fall out.

[0039] Please see Figure 3 and Figure 5 The left and right sides of the cut edge 210 are also provided with a toggle frame 230. The toggle frame 230 includes a drive cylinder 231 and a gear 232. The drive cylinder 231 is set on the bracket 211. The telescopic end of the drive cylinder 231 is provided with a rack 233 that meshes with the gear 232. A lever 234 is fixedly connected to the gear 232. Because one of the side brackets 211 will enter between the front and rear brackets 211 under the drive of the linear module B130, when the frame is cut off, it will interfere with the edge of the bracket 211. At this time, the drive cylinder 231 drives the rack 233 to move, drives the gear 232 to rotate, and then drives the lever 234 to rotate, pushing the frame back a short distance to avoid the edge of the bracket 211. Then the push-pull plate 223 can smoothly pull the frame back to the gap and drop it. The push-pull plate 223 and the lever 234 work together to realize the actions of pushing, pulling, pushing and dropping the frame. It can smoothly collect the aluminum frame that has been punched off, and has the advantages of reasonable layout, good compatibility and high degree of automation.

[0040] Please see Figures 2-3 The frame 110 is equipped with a lifting cylinder 140 at its front end. When the three sides of the frame are cut off together, the rear part of the photovoltaic panel will fall onto the transfer component 120, while the front part of the photovoltaic panel will fall onto the lifting cylinder 140. At this time, the lifting cylinder 140 will lift the photovoltaic panel above the height of the support plate 215 so that the transfer component 120 can smoothly push the photovoltaic panel away from the frame 110. This has the advantages of high reliability and high degree of automation.

[0041] Please see Figures 1-5 The frame 110 is surrounded by a perimeter panel 150, on which a controller 160 is mounted. An oil supply mechanism 170 is located at the top of the frame 110. The controller 160 controls the equipment to operate according to a set program, achieving automation. The oil supply mechanism 170 provides hydraulic oil to the hydraulic cylinder 212.

[0042] The working principle of this fully automatic punching machine for discarded photovoltaic modules is as follows: The cutting edge piece 210 on one side moves inward under the push of the linear module B130 to fit the photovoltaic module panel of the current width. Then, the photovoltaic module panel enters the frame 110 from one of the cutting edge pieces 210. At this time, the front edge of the photovoltaic module panel is above the clamping plate 124. The lifting cylinder 122 lifts the clamping plate 124 and pulls the photovoltaic module panel forward. Then, the clamping plate 124 descends, and the push plate 123 rises, pressing against the inner side of the front edge, continuing to push the photovoltaic module panel until the rear edge of the photovoltaic module panel is located at the rear support plate 215. The hydraulic cylinder 212 pushes the blade 214 downward to punch the connection between the edge and the photovoltaic panel, thus removing the edge. Then, the vertical cylinder 221 and the horizontal cylinder 222 work together to drive the push-pull plate 223 to pull the edge back into the gap of the bracket 211 and drop it out. Then, the push plate... 123 pushes the photovoltaic module panel forward until it reaches the push-out plate at the front end. The push-pull plates 223 on both sides provide a limit for the photovoltaic module panel. Then, the cutting edge pieces 210 at the front end and on both sides move simultaneously to cut off the remaining frame. The rear part of the photovoltaic panel will fall onto the transfer piece 120, while the front part of the photovoltaic panel will fall onto the lifting cylinder 140. At this time, the lifting cylinder 140 lifts the photovoltaic panel above the height of the support plate 215. The push plate 123 pushes the rear end of the photovoltaic panel, pushing the photovoltaic panel away from the frame 110. The uniquely designed cutter, combined with the support component 100 and the punching component 200, solves the technical problem that tempered glass is generally considered to be uncut. In summary, the support component 100 uses the transfer piece 120 to help the photovoltaic module panel move within the frame 110 and align with the four cutting edge pieces 210. After the cutting edge pieces 210 have finished cutting, the transfer piece 120 is used to push the photovoltaic panel out, which effectively improves the efficiency of frame disassembly.
