Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic panel recycling, and in particular to a backboard removal device and photovoltaic panel disassembly equipment. Background Art

[0002] Photovoltaic panels need to be recycled after retirement. Photovoltaic panels are usually composed of structures such as battery panels, glass panels, power boxes and frames. In the process of photovoltaic panel recycling, the power boxes and frames are usually removed first, and then the glass panels and battery panels are separated. The battery panels are composed of back panels and battery cells. In order to avoid waste of recycled materials, the battery panels are usually peeled off, so that the back panels and battery cells are separated, so that the battery cells can be recycled separately.

[0003] In the related art, during the battery panel separation operation, the battery panel is immersed in an organic solvent such as trichloroethylene, which can dissolve the adhesive layer between the back panel and the battery cell, thereby separating the back panel from the battery cell.

[0004] However, the method of using organic solvents to separate the solar panels is slow and will produce harmful products such as toluene and acetaldehyde. Therefore, it is difficult to disassemble the solar panels of photovoltaic panels in related technologies. Summary of the invention

[0025] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the specific embodiments of the present invention and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0026] The technical solutions disclosed in various embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0027] like Figures 1 to 5 As shown, an embodiment of the present invention discloses a backboard removal device, which is used to separate the backboard and the battery sheet of a solar panel. The solar panel here refers to the remaining part of the photovoltaic panel after removing the power box, the frame and the glass plate. The disclosed backboard removal device includes a mounting frame 100 and a stripping mechanism 300.

[0028] The mounting frame 100 provides a mounting base for other components of the backboard removal device. Specifically, the stripping mechanism 300 is disposed on the mounting frame 100 .

[0029] The peeling mechanism 300 includes a hot knife 350, a first adsorption member 360 and a second adsorption member 370, and the hot knife 350 is arranged on the mounting frame 100. The hot knife 350 in the present application may include a tool body and a heating element, and the heating element here may be a contact heating component. For example, a heating wire may be provided on the tool body to heat the tool body. Alternatively, the heating element may be a non-contact structure, and the heating element may couple heat the tool body. Of course, the heating element may also be other structures, which are not limited in this article.

[0030] The first adsorption member 360 and the second adsorption member 370 are both movably connected to the mounting frame 100, and the first adsorption member 360 and the second adsorption member 370 can move between the feeding side of the stripping mechanism 300 and the discharging side of the stripping mechanism 300. At this time, the battery plate enters the stripping mechanism 300 from the feeding side, and the separated back plate and battery sheet are transferred out from the discharging side of the stripping mechanism 300.

[0031] In the specific operation process, the first adsorbent 360 and the second adsorbent 370 adsorb the battery panel on the feed side of the stripping mechanism 300, and the first adsorbent 360 and the second adsorbent 370 are used to be adsorbed on the opposite sides of the battery panel respectively. For example, the first adsorbent 360 can be adsorbed on the surface of the battery cell facing away from the back plate, and the second adsorbent 370 can be adsorbed on the surface of the back plate facing away from the battery cell. In the process of the first adsorbent 360 and the second adsorbent 370 moving from the feed side of the stripping mechanism 300 to the discharge side of the stripping mechanism 300, the first adsorbent 360 and the second adsorbent 370 can apply opposite forces to the opposite sides of the battery panel and the hot knife 350 cuts the adhesive layer between the battery cell and the back plate of the battery panel. Here it means that the blade of the hot knife 350 passes through the adhesive layer, so that the battery cell and the back plate are separated.

[0032] In addition, the first adsorbent 360 and the second adsorbent 370 can apply a pulling force between the back plate and the battery cell, so as to tear the adhesive layer, thereby making it easier to peel the back plate and the battery cell. In addition, the hot knife 350 has a certain temperature, so when the hot knife 350 contacts the adhesive layer, the hot knife 350 can heat the adhesive layer between the back plate and the battery plate, thereby melting the adhesive layer, making it easier for the hot knife 350 to cut the adhesive layer, thereby making it easier for the hot knife 350 to peel the battery cell and the back plate.

[0033] The backboard removal device disclosed in the present application can more quickly peel off the solar panel by cutting the solar panel with the hot knife 350 and tearing the solar panel in the opposite direction, thereby improving the stripping efficiency of the solar panel. In addition, this separation method is not easy to produce harmful gases. Therefore, the backboard removal device disclosed in the present application can reduce the difficulty of disassembling the solar panel of the photovoltaic panel.

[0034] In the scheme disclosed in the present application, during the process of separating the battery cell and the backplane by the hot knife 350, one of the battery cell and the backplane is transferred from the top of the hot knife 350, and the other is transferred from the bottom of the hot knife 350. That is to say, the battery cell and the backplane are respectively transferred out of the peeling mechanism 300 from both sides of the hot knife 350. Therefore, the discharge side of the peeling mechanism 300 has two discharge ports, and the two discharge ports are respectively located on both sides of the hot knife 350. One discharge port is used to transfer the battery cell, namely the battery cell discharge port, and the other discharge port is used to transfer the backplane, namely the backplane discharge port. Specifically, the battery cell discharge port is formed on the upper side of the hot knife 350, and the backplane discharge port is formed on the lower side of the hot knife 350. At this time, the separated backplane is transferred out from the backplane discharge port, and the separated battery cell is transferred out from the battery cell discharge port.

[0035] In the above embodiment, the first adsorption member 360 and the second adsorption member 370 can be connected to the mounting frame 100 through a guide rail, and the first adsorption member 360 and the second adsorption member 370 can be a telescopic rod structure. The operator can manually push the first adsorption member 360 and the second adsorption member 370 to move, and at the same time, apply a contraction force to the first adsorption member 360 and the second adsorption member 370 that can make the first adsorption member 360 and the second adsorption member 370 relatively away from each other, so that the first adsorption member 360 and the second adsorption member 370 can apply opposite forces to the two sides of the solar panel. At this time, the process of the first adsorption member 360 and the second adsorption member 370 sucking materials, applying opposite forces to the two sides of the solar panel, and moving and cutting can all be completed manually by the operator.

[0036] In another optional solution, the peeling mechanism 300 may further include a first power mechanism 301, which may include a first driving unit 310 and a first force member 330. The first driving unit 310 may be disposed on the mounting frame 100, and the first driving unit 310 may be connected to the first force member 330, and the first force member 330 may be connected to the first adsorption member 360. The first driving unit 310 may drive the first adsorption member 360 to move between the feeding side of the peeling mechanism 300 and the discharging side of the peeling mechanism 300 through the first force member 330. The first force member 330 may apply a force to the first adsorption member 360 that is away from the second adsorption member 370.

[0037] The peeling mechanism 300 may further include a second power mechanism 302, which may include a second driving unit 320 and a second force member 340. The second driving unit 320 may be disposed on the mounting frame 100, the second driving unit 320 may be connected to the second force member 340, the second force member 340 may be connected to the second adsorption member 370, and the second driving unit 320 may drive the second adsorption member 370 to move between the feeding side of the peeling mechanism 300 and the discharging side of the peeling mechanism 300 through the second force member 340. The second force member 340 may apply a force to the second adsorption member 370 away from the first adsorption member 360.

[0038] During the specific operation, the first driving part 310 moves the first adsorption member 360 to the feeding side of the stripping mechanism 300 through the first force member 330; the second driving part 320 moves the second adsorption member 370 to the feeding side of the stripping mechanism 300 through the second force member 340. Then the first adsorption member 360 is adsorbed on the upper surface of the battery panel, and the second adsorption member 370 is adsorbed on the lower surface of the battery panel. At this time, the first force member 330 and the second force member 340 apply forces in opposite directions to the battery panel, and then the first driving part 310 and the second driving part 320 drive the first adsorption member 360 and the second adsorption member 370 to move toward the discharging side of the stripping mechanism 300, and the hot knife 350 can perform a cutting operation on the battery panel.

[0039] In this solution, the first power mechanism 301 and the second power mechanism 302 can drive the first adsorption member 360 and the second adsorption member 370 to move, thereby reducing manual intervention, thereby improving the stripping efficiency of the backing plate removal device and realizing the automation of the backing plate removal device.

[0040] Optionally, the first driving part 310 and the second driving part 320 can be power structures such as cylinders, hydraulic cylinders, motors, etc. Of course, the first driving part 310 and the second driving part 320 can also be other power structures, which are not limited in this article. The first force applying member 330 and the second force applying member 340 here can be elastic structural members such as elastic ropes and springs. After the first adsorption member 360 and the second adsorption member 370 are adsorbed on the battery panel, the elastic structural member is stretched, thereby providing a force in the opposite direction to the battery panel.

[0041] In another optional embodiment, the first driving part 310 can drive the first adsorption member 360 to move along the first direction through the first force member 330. The first force member 330 can be a third driving part. The third driving part can drive the first adsorption member 360 to move along the second direction. The second driving part 320 can drive the second adsorption member 370 to move along the first direction through the second force member 340. The second force member 340 can be a fourth driving part, and the fourth driving part can drive the second adsorption member 370 to move along the second direction. Among them, the first direction can be perpendicular to the second direction. The first direction here can be the direction from the feed side of the stripping mechanism 300 to the discharge side of the stripping mechanism 300, or the direction from the discharge side of the stripping mechanism 300 to the feed side of the stripping mechanism 300. Of course, it can also be understood as the transmission direction of the stripping mechanism 300. The second direction is a direction perpendicular to the transmission direction of the stripping mechanism 300. For example, the first direction can be a horizontal direction, and the second direction can be a vertical direction.

[0042] In the specific operation process, the first driving unit 310 and the second driving unit 320 respectively drive the first adsorbent 360 and the second adsorbent 370 to the feeding side of the stripping mechanism 300. At this time, the first adsorbent 360 is above the battery panel and the second adsorbent 370 is below the battery panel. Then the third driving unit and the fourth driving unit respectively drive the first adsorbent 360 and the second adsorbent 370 to approach the battery panel, so that the first adsorbent 360 and the second adsorbent 370 are respectively adsorbed on the opposite sides of the battery panel.

[0043] In this solution, the backboard removal device can automatically load and unload materials through the third driving unit and the fourth driving unit, thereby avoiding human intervention and further improving the automation performance of the backboard removal device.

[0044] Optionally, the third driving unit and the fourth driving unit may be power structures such as a cylinder, a hydraulic cylinder, a motor, etc. Of course, the third driving unit and the fourth driving unit may also be other power structures, which is not limited in this article.

[0045] In another optional solution, the backboard removal device may further include a feed conveying mechanism 200 , which may be disposed on the mounting frame 100 , and the feed conveying mechanism 200 may be used to convey the solar panel from the loading position to the feed side of the stripping mechanism 300 .

[0046] During the specific operation, the feed transmission mechanism 200 receives the separated battery panels from the device of the previous separation process, and then transmits the battery panels to the feed side of the stripping mechanism 300. The first adsorption member 360 and the second adsorption member 370 absorb the battery panels from the feed side of the stripping mechanism 300, and then drive the battery panels to move from the feed side of the stripping mechanism 300 to the discharge side of the stripping mechanism 300, thereby performing the stripping operation.

[0047] In this solution, the loading of the backboard removal device is transmitted through a corresponding mechanism, thereby reducing human involvement, further improving the automation performance of the backboard removal device, and further improving the stripping efficiency of the backboard removal device.

[0048] In an optional solution, the feed conveying mechanism 200 may be a conveyor belt mechanism, which may include a first conveyor belt, a second conveyor belt, and a conveyor belt driving mechanism, wherein the first conveyor belt and the second conveyor belt are arranged in parallel to the mounting frame 100. The conveyor belt driving mechanism may be connected to both the first conveyor belt and the second conveyor belt to drive the first conveyor belt and the second conveyor belt to drive. During the transmission process of the first conveyor belt and the second conveyor belt, the battery panel may be driven to be transferred from the loading position to the feeding side of the stripping mechanism 300.

[0049] The above-mentioned conveyor belt driving mechanism may include a motor, a driving shaft and a driven shaft. The first conveyor belt and the second conveyor belt may be respectively mounted on the driving shaft and the driven shaft. The motor is axially connected to the driving shaft. The motor drives the driving shaft to rotate, thereby driving the first conveyor belt and the second conveyor belt to move. Of course, the conveyor belt driving mechanism may also be a gear rack, a worm gear, or other mechanism. The specific structure of the conveyor belt driving mechanism is not limited in this article.

[0050] In another optional solution, the backplane removal device may further include a heating mechanism 400, which may be disposed on the mounting frame 100. The heating mechanism 400 is used to heat the battery panel during the process in which the feed conveying mechanism 200 drives the battery panel to be transferred to the feed side of the stripping mechanism 300. In this solution, the heating mechanism 400 can heat the adhesive layer between the battery cell and the backplane, thereby softening the adhesive layer, thereby making it easier to strip the battery cell and the backplane in the subsequent process.

[0051] In the above embodiment, in order to prevent the back sheet from softening, the feed conveying mechanism 200 needs to control the conveying speed of the solar panel and the heating temperature of the heating mechanism 400 during the conveying of the solar panel, so that only the adhesive layer is softened and the back sheet is not softened.

[0052] Optionally, the heating mechanism 400 may be a heating wire, a heating plate or the like. Of course, the heating structure may also be other structures which are not limited herein.

[0053] When the feed conveying mechanism 200 is the above-mentioned conveyor belt mechanism, the heating mechanism 400 may be located between the first conveyor belt and the second conveyor belt.

[0054] In another optional solution, the feed conveying mechanism 200 may include a fifth driving unit 210, a movable slide 220, a sixth driving unit 230 and a third adsorbent 240. The movable slide 220 is movably connected to the mounting frame 100 through the fifth driving unit 210. The fifth driving unit 210 can drive the movable slide 220 to move along the conveying direction of the feed conveying mechanism 200. The sixth driving unit 230 can be arranged on the movable slide 220. The sixth driving unit 230 is connected to the third adsorbent 240. The direction in which the sixth driving unit 230 drives the third adsorbent 240 to move is perpendicular to the direction in which the fifth driving unit 210 drives the movable slide 220 to move. The third adsorbent 240 can be arranged opposite to the heating mechanism 400.

[0055] During the specific operation, the fifth driving unit 210 drives the movable slide 220 to move to the loading position, and then the sixth driving unit 230 drives the third adsorption member 240 to move to receive the battery panel from the device of the previous disassembly process. Then the fifth driving unit 210 drives the movable slide 220 to be transferred toward the feeding side of the stripping mechanism 300. During the transfer process, the heating mechanism 400 is turned on to heat the battery panel to be disassembled synchronously. After being transferred to the feeding side of the stripping mechanism 300, the stripping mechanism 300 receives the battery panel to be disassembled from the third adsorption member 240.

[0056] In this solution, the third adsorbent 240 can move in two perpendicular directions, so it is easy to adjust the position of the third adsorbent 240, thereby improving the loading and unloading accuracy of the third adsorbent 240. In addition, the sixth driving unit 230 can drive the third adsorbent 240 to move in a direction close to or away from the heating mechanism 400, so it is easy to adjust the distance between the third adsorbent 240 and the heating mechanism 400, so that the heating temperature of the solar panel can be controlled more accurately.

[0057] Optionally, the fifth driving unit 210 and the sixth driving unit 230 may both be power structures such as a cylinder, a hydraulic cylinder, or a linear motor.

[0058] In another optional embodiment, the fifth driving unit 210 may include a third driving motor 211 and a third lead screw 212, the third lead screw 212 may be rotatably connected to the mounting frame 100, the movable slide 220 may be mounted on the third lead screw 212, the third driving motor 211 may be connected to the third lead screw 212, and the third driving motor 211 may drive the movable slide 220 to move along the third lead screw 212. At this time, the third driving motor 211 may drive the third lead screw 212 to rotate, and during the rotation of the third lead screw 212, the movable slide 220 may be driven to move along the axis direction of the third lead screw 212. According to the different rotation directions of the rotating shaft of the third driving motor 211, the reciprocating movement of the movable slide 220 may be realized.

[0059] This solution can realize long-distance transmission of the mobile slide 220, thereby improving the reliability of transmission.

[0060] In the above embodiment, the fifth driving part 210 can be the screw transmission structure disclosed above, and the sixth driving part 230 can be a cylinder, the cylinder body of the cylinder is fixed on the movable slide 220, and the telescopic shaft of the cylinder is connected to the third adsorption component 240.

[0061] In the above embodiment, the number of the third lead screws 212 can be multiple, and the multiple third lead screws 212 can be connected by a transmission mechanism such as a chain, a conveyor belt, a gear set, etc., so when there is only one third drive motor 211, multiple third lead screws 212 can be driven to rotate simultaneously. The number of the third lead screws 212 can be two, and the two third lead screws 212 can be connected to the two ends opposite to the movable slide 220 respectively.

[0062] In another optional embodiment, a first guide portion, such as a guide rail, a guide rod or other guide structure, may also be provided on the mounting frame 100 . The first guide portion may cooperate with the guide of the movable slide 220 , thereby further improving the movement accuracy of the movable slide 220 .

[0063] In order to facilitate the collection of the backboard, in another optional solution, the backboard removal device may further include a slicing mechanism 500, and the separated backboard may be transferred to the slicing mechanism 500 through the discharge side of the peeling mechanism 300, and the slicing mechanism 500 is used to cut the backboard into pieces. In this case, the backboard discharge port is provided with a slicing mechanism 500, and the backboard is transferred to the slicing mechanism 500 from the backboard discharge port.

[0064] This solution can directly slice and recycle the backplane, avoiding the process operation of secondary processing of the backplane, thereby further improving the recycling efficiency of the backplane removal device.

[0065] Optionally, the slicing mechanism 500 may include two knives arranged opposite to each other, the blades of the two knives being arranged opposite to each other, one of the blades being capable of reciprocating relative to the other blade, and the blades of the two knives being capable of performing a cutting and slicing operation on the back plate. It can be understood here that when the blades of the two knives are closed, the cutting operation on the back plate can be performed.

[0066] In another embodiment, the slicing mechanism 500 includes a connecting bracket 510, a rotating cutter head 520, a roller 530 and a seventh driving unit 540, and the connecting bracket 510 is the installation base of the slicing mechanism 500. The connecting bracket 510 can be connected to the mounting frame 100, and the connecting bracket 510 here can be integrally formed with the mounting frame 100, and of course, the mounting frame 100 can also be separately formed, which is not limited herein.

[0067] The rotating cutter head 520 can be rotatably connected to the connecting bracket 510, the roller 530 can be connected to the connecting bracket 510, the seventh driving unit 540 can be arranged on the mounting frame 100, the seventh driving unit 540 can be transmission-connected to the rotating cutter head 520, and the seventh driving unit 540 can drive the rotating cutter head 520 to rotate so that the back plate is cut into pieces under the squeezing action of the rotating cutter head 520 and the roller 530.

[0068] During the specific slicing process, the back plate can be passed between the rotating cutter head 520 and the roller 530. The rotating cutter head 520 can realize the transmission of the back plate in the slicing mechanism 500 when rotating. At the same time, the squeezing effect between the rotating cutter head 520 and the roller 530 can also break the back plate, thereby cutting the back plate into pieces.

[0069] The slicing mechanism 500 in this solution has good cutting efficiency, and the structure of the slicing mechanism 500 is relatively simple, thereby reducing the manufacturing cost of the backboard removal device.

[0070] In another optional embodiment, the mounting frame 100 may be provided with a partition 110, the hot knife 350 may be located between the partition 110 and the feeding side of the peeling mechanism 300, the partition 110 has a first side and a second side opposite to each other, the first adsorbent 360 moves on the first side of the partition 110, and the second adsorbent 370 moves on the second side of the partition 110. It can be understood here that the first side of the partition 110 is the battery cell discharge port, and the second side of the partition 110 is the backplane discharge port.

[0071] In this solution, the separator 110 separates the cell outlet and the backplane outlet, thereby avoiding the risk of the upper cell suddenly falling and affecting the transmission of the lower backplane, thereby improving the safety and reliability of the backplane removal device. In addition, the cell is relatively soft, and the part of the cell away from the first adsorption member 360 is prone to droop, so the separator 110 can also provide auxiliary support for the sagging area of ​​the cell.

[0072] In another optional embodiment, the separator 110 may include a plurality of rollers 111, which may be spaced apart from each other along the direction from the feeding side of the stripping mechanism 300 to the discharging side of the stripping mechanism 300, and the plurality of rollers 111 are rotatably connected to the mounting frame 100. In this solution, the battery cell may roll with the rollers 111 during the transmission process, thereby reducing the friction between the battery cell and the separator 110, thereby making it easier to transmit the battery cell.

[0073] In another optional solution, the first driving part 310 may include a first driving motor 311 and a first lead screw 312, and the first lead screw 312 may be rotatably connected to the mounting frame 100. The first force applying member 330 may be mounted on the first lead screw 312. The first driving motor 311 may be connected to the first lead screw 312, and the first driving motor 311 may drive the first force applying member 330 to move through the first lead screw 312, so as to drive the first adsorption member 360 to move between the feeding side of the stripping mechanism 300 and the discharging side of the stripping mechanism 300.
