Description

Technical Field

[0001] This application relates to the field of photovoltaic module recycling, and in particular to a photovoltaic module scrapping and recycling equipment and its production line. Background Technology

[0002] With the rapid development of the photovoltaic industry, the amount of scrapped photovoltaic modules is increasing year by year. How to efficiently and environmentally recycle and dispose of scrapped photovoltaic modules has become an urgent problem for the industry. At present, the recycling and disposal technology for scrapped photovoltaic modules is still in the development stage. Existing methods mainly rely on manual dismantling. Workers need to manually remove the module frame and separate the internal materials such as glass and backsheet. This method is inefficient, labor-intensive, and poses safety hazards, making it difficult to meet the needs of large-scale recycling and disposal. In terms of glass processing, existing technology usually involves manually transporting intact glass to a special glass recycling area, which is inefficient and prone to secondary damage. For broken glass, it is necessary to first clean and collect it before further processing, which is a cumbersome process and difficult to automate. Summary of the Invention

[0055] Photovoltaic modules mainly consist of frames, glass, and backsheets. Currently, the dismantling and recycling of photovoltaic modules usually requires manual loading and handling, as well as manual separation of the frames, glass, and backsheets. However, the handling and dismantling process can easily cause injury to workers.

[0056] This application provides a photovoltaic module scrapping and recycling device. The photovoltaic module includes a frame, glass and a backsheet. The photovoltaic module scrapping and recycling device includes a feeding and handling component 100, a frame dismantling component 200, a glass identification device 300, a flipping component 400, a peeling component 500 and a crushing component 600.

[0057] In some embodiments, the feeding and conveying assembly 100 is used for feeding photovoltaic modules, the frame removal assembly 200 is located downstream of the feeding and conveying assembly 100 and is used for frame removal, the glass identification device 300 is located downstream of the frame removal assembly 200 and is used for identifying the integrity of the glass, the integrity of the glass having a first state and a second state, the flipping assembly 400 is located downstream of the glass identification device 300 and is used for flipping the back sheet of the glass in the first state, the peeling assembly 500 is located downstream of the glass identification device 300 and is used for separating the glass from the back sheet in the second state, and the breaking assembly 600 is located on one side of the peeling assembly 500 and is used for separating the glass from the back sheet in the first state.

[0058] See Figure 1As shown, in the initial state, the frame, glass, and back panel are connected and fixed to form a whole, and the photovoltaic modules are stacked and placed at the loading position of the loading and transporting component 100. When the photovoltaic modules need to be disassembled and recycled, the loading and transporting component 100 grabs and transports the top photovoltaic module to the unloading position with the glass facing up. The photovoltaic module at the unloading position is transported to the frame disassembly component 200. The frame disassembly component 200 separates the frame of the photovoltaic module from the back panel, thus realizing the disassembly of the frame.

[0059] Furthermore, after disassembly, the back panel and glass are transported to the glass identification device 300. The glass identification device 300 identifies the state of the glass on the back panel to determine its integrity. Depending on the integrity of the glass, it is transported to the peeling assembly 500 or the breaking assembly 600. The back panel with glass in the first state is flipped by the flipping assembly 400 so that the glass face is down. At this time, the back panel is moved to the breaking assembly 600, which separates the glass in the first state from the back panel. It can be understood that the back panel with glass in the second state is transported to the peeling assembly 500 to separate the glass in the second state from the back panel, thereby realizing the separation of glass from the back panel in different states.

[0060] Furthermore, the glass recognition device 300 is formed by combining a high-resolution industrial camera (with a resolution of over 5 million pixels) with a multi-source illumination device. It can accurately acquire clear and accurate images. Through the image processing algorithm of the vision system based on deep learning technology and trained on a large number of samples, it can quickly and accurately analyze the integrity of the glass, thereby determining whether the glass is in the first or second state.

[0061] It should be noted that the glass in the first state is broken, i.e., shattered glass, while the glass in the second state is intact, i.e., not broken, and can be reused.

[0062] The feeding end of the frame removal assembly 200 is provided with a feeding conveyor line 1010, which is used to transport the photovoltaic modules from the feeding and handling assembly 100 to the frame removal assembly 200. A first transfer conveyor line 1020 is provided between the glass identification device 300 and the peeling assembly 500. A second transfer conveyor line 1030 is provided on one side of the first transfer conveyor line 1020. The second transfer conveyor line 1030 is located at the feeding end of the crushing assembly 600. The first transfer conveyor line 1020 and the second transfer conveyor line 1030 are arranged in parallel. The flipping assembly 400 is located between the first transfer conveyor line 1020 and the second transfer conveyor line 1030.

[0063] Please continue reading. Figure 1As shown, in order to enable the photovoltaic modules to be transferred to the frame removal assembly 200, and the backsheet with glass to be transferred to the glass identification device 300, the peeling assembly 500, and the crushing assembly 600, a feeding conveyor line 1010 is set between the frame removal assembly 200 and the feeding and conveying assembly 100. The photovoltaic modules are transported to the frame removal assembly 200 via the feeding conveyor line 1010. A first transfer conveyor line 1020 is set between the glass identification device 300 and the peeling assembly 500 to transport the backsheet with glass in the second state to the peeling assembly 500. In order to enable the backsheet with glass in the first state to be transported to the crushing assembly 600, a second transfer conveyor line 1030 is set at the inlet of the crushing assembly 600. The flipping assembly 400 flips the backsheet with glass in the first state to the second transfer conveyor line 1030, and then the backsheet with glass in the first state is transported to the crushing assembly 600 via the second transfer conveyor line 1030. The crushing assembly 600 separates the glass in the first state from the backsheet.

[0064] In this embodiment, the feeding conveyor line 1010, the first transfer conveyor line 1020, and the second transfer conveyor line 1030 are all roller conveyor lines.

[0065] In one embodiment, the back panel also has a junction box. When disassembling the frame, the junction box also needs to be disassembled to separate it from the back panel. Furthermore, the frame removal assembly 200 includes cylinders located on the four sides of the frame. Each cylinder has a frame clamp at its telescopic end. The frame is removed by moving the frame clamp. The frame clamp can be adaptively adjusted according to different types of frames, and the specific structure is not limited. Below the photovoltaic module at this location, there is also a cylinder with the same number of cylinders as the junction box. The telescopic end of the cylinder has a scraper. The cylinder drives the scraper to move and scrape off the junction box to separate it from the back panel. To prevent the photovoltaic module from shifting position, a cylinder can be set above it. The telescopic end of the cylinder at this location has a pressing plate. The pressing plate presses and fixes the photovoltaic module to prevent it from shifting position. Specifically, the junction box can be removed first, and then the frame can be removed. The above is just an example of one technical solution that can remove the frame. Other solutions in the prior art can also be referred to, that is, other existing technical solutions can be used to replace the above solutions. Specific limitations are not made here.

[0066] The material handling assembly 100 includes a mounting frame 110, a first linear module 120, a second linear module 130, a driven frame 140, and multiple suction cups 150.

[0067] In one embodiment, a first linear module 120 is fixedly mounted on a mounting bracket 110 and can move along a first preset direction. A second linear module 130 is mounted on the moving end of the mounting bracket 110 and can move along a second preset direction. A driven bracket 140 is fixedly mounted on the moving end of the second linear module 130, and a suction cup 150 is fixedly mounted on the driven bracket 140.

[0068] See Figure 2 As shown, the first linear module 120 and the second linear module 130 are linked to achieve movement in the first preset direction and the second preset direction, which in turn can drive the driven frame 140 located on the suction cup 150 to move in position, that is, to achieve two-axis movement. In this embodiment, the suction cup 150 is used to transport the photovoltaic module.

[0069] It should be noted that the first linear module 120 and the second linear module 130 can both be motor screw linear modules, gear rack linear modules, or linear motor modules, etc., that is, as long as linear movement can be achieved. It can be understood that the first preset direction mentioned above is the horizontal direction, and the second preset direction is the height lifting direction. Of course, another linear module can be added on this basis, which can achieve horizontal, vertical and height movement by linkage with the first linear module and the second linear module.

[0070] The flipping assembly 400 includes a rotation drive 410, a rotating shaft 420, at least one first fixing plate 430, and at least one second fixing plate 440.

[0071] In this embodiment, the rotating shaft 420 is fixedly installed on the rotating end of the rotating drive member 410. The rotating drive member 410 drives the rotating shaft 420 to rotate. The first fixing plate 430 is fixedly installed on the rotating shaft 420, and the second fixing plate 440 is fixedly installed on the rotating shaft 420. The number of the second fixing plate 440 is the same as that of the first fixing plate 430. The second fixing plate 440 and the first fixing plate 430 are arranged parallel to each other, and the second fixing plate 440 and the first fixing plate 430 form a first preset distance.

[0072] See Figure 1 , Figure 3 and Figure 4As shown, when it is necessary to flip the back panel with the first state glass, the first transfer conveyor line 1020 conveys the back panel to the space between the first fixed plate 430 and the second fixed plate 440. Then, the rotation drive 410 drives the rotating shaft 420 to rotate 180 degrees, thereby also driving the back panel located between the first fixed plate 430 and the second fixed plate 440 to rotate 180 degrees. At this time, the glass surface is facing down and the back panel surface is facing up. Then, the back panel is flipped onto the second transfer conveyor line 1030. The second transfer conveyor line 1030 conveys the back panel with the first state glass to the crushing assembly 600 to achieve the separation of the glass and the back panel.

[0073] It should be noted that in order to enable the back panel to flip smoothly, the first preset distance between the first fixing plate 430 and the second fixing plate 440 should be greater than the thickness of the back panel. In order to enable the flipping smoothly, each side should have at least two sets of first fixing plates 430 and second fixing plates 440. The width and length of the first fixing plate 430 and the second fixing plate 440 can be designed and adjusted according to the length and weight of the back panel, and are not limited here.

[0074] The peeling assembly 500 includes a mounting base 510, a first pressure roller 520, a second pressure roller 530, and a peeling blade 540. The first pressure roller 520 is fixedly mounted on the mounting base 510, and the second pressure roller 530 is disposed above the first pressure roller 520. The first pressure roller 520 and the second pressure roller 530 form a second preset distance. The peeling blade 540 is fixedly mounted on the mounting base 510. The mounting base 510 is used to separate the glass from the backing plate in the second state.

[0075] See Figure 1 and Figure 5 As shown, in this embodiment, the peeling assembly 500 separates the complete glass from the back plate. Specifically, the back plate with complete glass is transported to the space between the first pressure roller 520 and the second pressure roller 530 via the first transfer conveyor line 1020. Since the cutting point of the peeling knife 540 is located between the glass and the back plate, as the first pressure roller 520 and the second pressure roller 530 rotate, the back plate moves, and the peeling knife 540 gradually separates the glass from the back plate.

[0076] Furthermore, in order to further improve the separation efficiency between the glass and the backing plate, the peeling blade 540 can be a hot blade that can generate a certain temperature, which can ensure the separation of the backing plate and the glass while preventing damage to the glass. Specifically, the peeling blade 540 is made of high-quality alloy high-speed steel.

[0077] Furthermore, in order to precisely control the movement of the peeling blade 540 so that its cutting point is located between the glass and the back plate, the peeling blade 540 can be mounted on a three-axis module (which can be formed by assembling three motor lead screw linear modules) to ensure the separation of the back plate from the intact glass.

[0078] The crushing assembly 600 includes a heating conveying channel 610, a grinding assembly 620, a collection box 630, and a first back plate conveying line 640. The grinding assembly 620 is located at the position of the heating conveying channel 610, the collection box 630 is located below the heating conveying channel 610, and the first back plate conveying line 640 is located at the end of the heating conveying channel 610.

[0079] See Figure 1 As shown, in order to separate the broken glass from the backing plate, the backing plate and the broken glass are first heated through the heating conveyor channel 610, so that they can be separated better during separation and the adhesive between the glass and the backing plate is reduced. After heating, they are conveyed to the grinding component 620, where the grinding component 620 grinds and crushes the broken glass, thereby separating the broken glass from the backing plate. The broken glass will fall into the collection box 630 below for collection. Finally, the backing plate is conveyed to the next process through the first backing plate conveyor line 640.

[0080] It should be noted that the grinding component 620 is a sanding roller, which can be driven to rotate by a motor. It is made of high-strength tungsten carbide material and has a frosted texture on the surface, which can effectively grind and crush glass.

[0081] A lifting support platform 700 is provided downstream of the stripping component 500. A conveying component 900 is also provided between the lifting support platform 700 and the stripping component 500. The conveying component 900 conveys the glass in the second state to the lifting support platform 700 for stacking.

[0082] Please continue reading. Figure 1 As shown, since the glass peeled off by the peeling component 500 is a complete and undamaged whole piece of glass, the complete glass can be reused. Specifically, after the glass is separated, it is transported by the conveying component 900 to the lifting support platform 700 for stacking, so as to realize the stacking and collection of complete glass.

[0083] It is understandable that the lifting platform 700 can achieve a certain height, that is, it can also achieve a height of one glass thickness. Specifically, when the lifting platform 700 stacks a piece of glass, the lifting platform 700 should descend by the height of one glass thickness so that the lifting platform 700 can stack and collect the next piece of glass.

[0084] The conveying assembly 900 includes a first glass conveying line 910, a second glass conveying line 920 is provided downstream of the first glass conveying line 910, a lifting support platform 700 is located on one side of the second glass conveying line 920, and a second backplate conveying line is provided below the first glass conveying line 910.

[0085] like Figure 1 As shown, the lifting platform 700 is located on one side of the second glass conveying line 920. In order to transport complete glass to the lifting platform 700, the conveying direction of the second glass conveying line 920 should be perpendicular to the conveying direction of the first glass conveying line 910, thereby changing the conveying direction so that the glass can be smoothly transported to the lifting platform 700.

[0086] Furthermore, since the stripping assembly 500 separates the backplate from the complete glass, the separated glass is transported by the first glass conveyor line 910 and the second glass conveyor line 920 to the lifting support platform 700 for stacking and collection. The separated backplate is then transferred to the second backplate conveyor line (not shown) below the first glass conveyor line 910, and the backplate is transported to the next process via the first glass conveyor line 910. The second backplate conveyor line should use a high-temperature resistant and corrosion-resistant conveyor belt.

[0087] The waste recycling equipment also includes a crushing and recycling component 800, which includes a crushing component 810. A vibrating screen 820 is provided at the outlet of the crushing component 810. A gravity separation device 830 is provided at the discharge port of the vibrating screen 820. Downstream of the gravity separation device 830 are a first grading device 840, a second grading device 850, and a dust removal device 860.

[0088] In this embodiment, the crushing component 810 is divided into coarse crushing and fine crushing, with coarse crushing first and then fine crushing. The specific device for implementing coarse crushing and fine crushing is not limited here, and can be selected and used as needed.

[0089] The backplate contains EVA adhesive, solder ribbon, copper silicon powder, impurities, etc., so it is necessary to crush the backplate and classify and collect the different materials inside.

[0090] See Figure 2 and Figure 6As shown, the ends of the first backplate conveyor line 640 and the second backplate conveyor line converge at the inlet of the crushing assembly 810. The crushing assembly 810 has a conveyor line at its feed end, through which the backplates from the first backplate conveyor line 640 and the second backplate conveyor line are conveyed to the crushing assembly 810 for crushing. In one embodiment, the backplates from the first backplate conveyor line 640 and the second backplate conveyor line are first crushed by the crushing assembly 810. The crushed backplate powder is then conveyed to a vibrating screen 820, where EVA glue is separated. The backplate powder is then conveyed to a gravity separator 830, where copper granules are separated. Next, the backplate powder is conveyed sequentially to a first grading device 840 and a second grading device 850, where different coarse and fine materials are separated. Finally, the particles that meet the requirements are collected in a dust removal device 860.

[0091] In one embodiment, the gravity separation device 830 is a gravity separator, the first grading device 840 and the second grading device 850 are both grading machines, and the dust removal device 860 is a dust collector.
