Description

Technical Field

[0001] The present invention belongs to the technical field of separation and recovery of photovoltaic modules, and in particular relates to a device for separating and recovering battery materials in a crystalline silicon photovoltaic module. Background Art

[0002] Photovoltaic modules are photovoltaic devices that are packaged from photovoltaic glass, solar cells, backplanes, aluminum frames, junction boxes, solder strips, adhesive films and other materials according to a certain production process and achieve a certain output power and output voltage under certain lighting conditions.

[0003] Most of the materials in waste photovoltaic modules can be recycled and reused, and the recycled materials also have considerable value. In addition, recycling photovoltaic modules can avoid wasting resources, reduce environmental pollution, and is conducive to the harmonious development of green ecology.

[0004] At present, the recycling of waste crystalline silicon photovoltaic modules is mainly divided into three steps. The first step is to disassemble the frame and junction box. Remove the frame and junction box from the module to obtain the laminate (glass / film / cell / film / backplane); the second step is to disassemble the laminate to obtain glass, battery, backplane, solder strip, film or their mixture; the third step is to separate the components. The obtained battery, solder strip or mixture is subdivided into components to recover the material components with higher purity, such as silicon, silver, aluminum, copper, etc. The disassembly of the laminate mainly adopts the following methods: 1. Physical method: The photovoltaic module is physically broken into particles, the particles are screened and classified, and then recycled separately; 2. Pyrolysis method: Directly heat the photovoltaic module at more than 500°C, remove the EVA material layer through reaction, and separate the other layers; 3. Solvent method: Use solvent to dissolve or swell the EVA material layer to separate the other layers.

[0030] The material receiving assembly includes a material receiving plate 33, and the material receiving assembly is provided with two groups, each group has three. The two side walls of the main frame 1 are provided with material receiving ports 30, and electric telescopic rods 31 are provided on both sides of the material receiving ports 30. One end of the electric telescopic rod 31 is fixedly connected to the main frame 1, and the other end of the electric telescopic rod 31 is fixedly connected to a connecting plate 32. The material receiving plate 33 is hinged to the connecting plate 32. The material receiving plate 33 is C-shaped and arranged in the material receiving port 30. The three material receiving plates 33 are used to receive the separated glass, battery cell and back plate from top to bottom, respectively. The bottom of the end of the material receiving plate 33 has a bulge, and the material receiving plate 33 It is slidingly connected to the main frame 1. In the default state, the electric telescopic rod 31 is in an extended state, and the raised part at the bottom of the receiving plate 33 is in contact with the main frame 1. When material needs to be received, the electric telescopic rod 31 on the corresponding side contracts, driving the receiving plate 33 to enter the main frame 1 for receiving the material; after the material receiving is completed, the electric telescopic rod 31 extends, bringing the receiving plate 33 out of the main frame 1, and the raised part at the end of the receiving plate 33 is in contact with the main frame 1, so that the receiving plate 33 is tilted, and the received material can slide into the receiving frames on both sides, thereby restoring to the default state.

[0031] It should be noted that the material receiving assembly on the left side of the main frame 1 is used to receive glass, battery cells and back panels that can be directly recycled and reused, and the right side is used to receive glass, battery cells and back panels that cannot be directly recycled and reused.

[0032] like Figure 2 and Figure 3 As shown, a support frame 6 is arranged on the left side of the conveyor belt 2 , the width of the support frame 6 is smaller than the width of the laminate 3 , and the support frame 6 is arranged inside the main frame 1 .

[0033] A long slide groove 7 and a short slide groove 8 are provided on the inner side walls of the main frame 1. There are four groups of long slide grooves 7 and two groups of short slide grooves 8. The cross-sections of the long slide grooves 7 and the short slide grooves 8 are both T-shaped. The long slide grooves 7 are located at the upper and lower positions of the side walls of the main frame 1, and the short slide grooves 8 are located in the middle position of the side walls of the main frame 1. A long screw rod 9 is provided in the long slide groove 7 on the right side wall of the main frame 1, and the long screw rod 9 is connected to the bearing of the main frame 1.

The short screw rod 11 passes through the main frame 1 and is fixedly connected to the output shaft of the second motor 12.

[0034] The split assembly includes a support block 13 and a connecting block 14. The support block 13 is provided with two groups. Both ends of the support block 13 are arranged in the long slide groove 7 and are threadedly connected to the long screw 9, and are slidably connected to the long slide groove 7. Both ends of the connecting block 14 are arranged in the short slide groove 8 and are threadedly connected to the short screw 11, and are slidably connected to the short slide groove 8. The right sides of the two groups of support blocks 13 are fixedly connected with connecting rods 15. The connecting rods 15 are provided with two groups to ensure that the two groups of support blocks 13 move synchronously. In the default state, the support The support block 13 is at the leftmost end of the long slide groove 7, and the connecting block 14 is at the leftmost end of the short slide groove 8. The first motor 10 and the second motor 12 start to rotate forward, driving the long screw 9 and the short screw 11 to rotate forward, thereby driving the support block 13 and the connecting block 14 to move right in the long slide groove 7 and the short slide groove 8. Conversely, the first motor 10 and the second motor 12 start to reverse, driving the support block 13 and the connecting block 14 to move left in the long slide groove 7 and the short slide groove 8, thereby realizing the left and right movement of the support block 13 and the connecting block 14.

[0035] A cylinder 16 is fixedly connected to the support block 13, and three groups of cylinders 16 are relatively arranged. A hinge 17 is fixedly connected to the end of the cylinder 16, and a suction cup 18 is fixedly connected to the other end of the hinge 17. The suction cup 18 is connected to a pipeline and an air pump. The cylinder 16 is started and extended, so that the suction cup 18 contacts the laminate 3 on the support frame 6. The air pump is started and the gas in the suction cup 18 is extracted through the pipeline, so that the air pressure inside the suction cup 18 is reduced, and then the cylinder 16 contracts to suck the laminate 3. Since the two groups of cylinders 16 are started at the same time, the heated laminate 3 can be separated.

[0036] A fixed block 19 is fixedly connected to the left side of the connecting block 14, and the fixed block 19 is provided with two groups. A limiting slide groove 20 is opened on the left side of the fixed block 19, and the cross-section of the limiting slide groove 20 is T-shaped. A bidirectional screw rod 21 and a chuck 22 are arranged in the limiting slide groove 20, and the chuck 22 is provided with two groups. The bidirectional screw rod 21 is connected to the bearing of the fixed block 19, and the bidirectional screw rod 21 is threadedly connected to the chuck 22. A third motor 23 is fixedly connected to the top of the fixed block 19, and the output shaft of the third motor 23 is fixedly connected to the bidirectional screw rod 21. When the third motor 23 starts to rotate forward, it drives the bidirectional screw rod 21 to rotate forward, and the two groups of chucks 22 move towards each other, so that the battery cells in the separated laminate 3 can be clamped. On the contrary, when the third motor 23 starts to reverse, the battery cells can be loosened.

[0037] like Figure 4 As shown, cameras 35 are fixedly connected to the upper and lower parts of the center of the connecting block 14. The cameras 35 are used to photograph whether there is any excess adhesive film adhered to the separated glass, battery cells, and back panel and their completeness.

[0038] like Figure 1 , Figure 3 and Figure 4As shown, the cleaning assembly includes a cleaning roller 24 and a glue removal groove 25. The cleaning roller 24 and the glue removal groove 25 are provided with two groups. One group of glue removal grooves 25 is located on the left side of the cleaning roller 24, and the other group is located on the right side of the cleaning roller 24. The cleaning roller 24 is connected to the main frame 1 by a bearing. The cleaning roller 24 includes a roller core 241. The surface of the roller core 241 is fixedly connected to a dot matrix pressure sensor 242. The dot matrix pressure sensor 242 is provided with a roller surface 243 on the outside. The two ends of the roller surface 243 are fixedly connected to the roller core 241. The two ends of the cleaning roller 24 are keyed to gears 26. The gears 26 mesh with each other. A fourth motor 34 is fixedly connected to the outer wall of the frame 1, and the cleaning roller 24 located above passes through the main frame 1 and is fixedly connected to the output shaft of the fourth motor 34. When the fourth motor 34 starts to rotate forward, it drives the upper cleaning roller 24 and the gear 26 to rotate forward. Since the gears 26 are meshed with each other, the lower cleaning roller 24 is driven to rotate reversely, so that the separated battery cells can be clamped and fed, and the softened adhesive film on the upper and lower surfaces of the battery cells can be adhered. Conversely, when the fourth motor 34 starts to reverse, it can also clamp and feed the battery cells, and adhere the softened adhesive film on the upper and lower surfaces, and it is also convenient for the subsequent removal of the adhesive film.

[0039] A rotating shaft 27 is fixedly connected to the bottom of the glue removal groove 25, a heating wire 28 is fixedly connected to the bottom of the glue removal groove 25 on the side close to the cleaning roller 24, a fifth motor 29 is fixedly connected to the outer wall of the main frame 1, and the rotating shaft 27 passes through the main frame 1 and is fixedly connected to the output shaft of the fifth motor 29. When the adhesive film adhered to the surface of the cleaning roller 24 reaches a certain thickness, the fifth motor 29 starts to rotate, driving the rotating shaft 27 to rotate, so that the side of the glue removal groove 25 close to the cleaning roller 24 is attached to the adhesive film on the surface of the cleaning roller 24, and at the same time, the heating wire 28 is heated to soften the adhesive film adhered to the surface of the cleaning roller 24, and the fourth motor 34 starts to reverse, so that the glue removal groove 25 removes the adhesive film adhered to the surface of the cleaning roller 24, thereby realizing self-cleaning of the cleaning component.

[0040] like Figure 5 As shown, the intelligent recognition system includes a picture recognition module, a pressure recognition module, a judgment module and a control module. The picture recognition module is electrically connected to the camera 35, the pressure recognition module is electrically connected to the dot matrix pressure sensor 242, and the control module is electrically connected to the first motor 10, the second motor 12, the cylinder 16, the suction cup 18, the third motor 23, the fourth motor 34, the fifth motor 29 and the electric telescopic rod 31.

[0041] The separation method of battery materials in photovoltaic modules is:

[0042] Step 1: placing the laminate 3 on the conveyor belt 2 and heating the laminate 3.

[0043] Step 2: Split the components and split the laminate 3, cleaning the components and sticking the softened adhesive film after splitting.

[0044] Specifically, splitting and cleaning includes the following steps:

[0045] S1: When the heated laminate 3 is placed on the support frame 6, the cylinder 16 starts to extend, and after the suction cup 18 contacts the upper and lower surfaces of the laminate 3, the air pump starts to extract the gas in the suction cup 18 and suck the laminate 3.

[0046] S2: The cylinder 16 contracts to separate the laminate 3 into glass, battery cells and backplane, and at the same time the first motor 10 starts to rotate forward, driving the support block 13 to move right synchronously.

[0047] S3: The battery cell passes through the roller gap between the two sets of cleaning rollers 24, and the cleaning rollers 24 adhere the softened adhesive film on the upper and lower surfaces of the battery cell, the glass and the back plate.

[0048] It should be noted that when the cylinder 16 contracts to separate the laminate 3 , the glass and the back plate come into contact with the surface of the cleaning roller 24 .

[0049] S4: When contacting the fixing block 19, the second motor 12 starts to rotate forward to drive the connecting block 14 to move right synchronously. At the same time, the third motor 23 starts to rotate forward to drive the clamping head 22 to move toward each other to clamp the battery cell.

[0050] S5: The fourth motor 34 starts to rotate forward, driving the upper cleaning roller 24 and the gear 26 to rotate forward. Since the gears 26 are meshed with each other, the lower cleaning roller 24 is driven to rotate reversely, so that the separated battery cells can be clamped and fed, and the softened adhesive films on the upper and lower surfaces of the battery cells can be adhered.

[0051] Step 3: The intelligent recognition system identifies the adhesive conditions on the surfaces of the three parts after separation.

[0052] Specifically, the intelligent recognition system includes the following steps:

[0053] A1: When the laminate 3 is separated and not all the battery cells come out of the roller gap of the cleaning roller 24, the dot matrix pressure sensor 242 transmits the pressure data to the pressure identification module.

[0054] Specifically, the pressure identification module identifies the pressure data and obtains the maximum pressure and the difference between the maximum pressure and the minimum pressure. Under normal circumstances, the difference between the maximum pressure and the minimum pressure in the allowable pressure data is N, the maximum pressure is M, and the actual difference is n and the maximum pressure is m.

[0055] A2: Camera 35 captures the upper and lower surfaces of the battery cell, the lower surface of the glass, and the upper surface of the back panel, and feeds it back to the image recognition module to identify whether there is any film that has not been removed and whether it is complete.

[0056] A3: The judgment module judges whether the battery cells, glass and back panel of the laminate 3 can be recycled and reused, and feeds back to the control module for corresponding operations.

[0057] When n>N, it means that the adhesive film between the laminates 3 is aged after long-term use, and the battery cells of the laminates 3 cannot be recycled and reused, but it does not affect the glass and the back panel.

[0058] When n≤N, it means that the adhesive film of the laminate 3 is in a normal state after long-term use, and the battery cells of the laminate 3 can be reused in a complete state without the adhesive film, so as to reduce resource waste.

[0059] If the battery cell, glass or back panel is intact and has no adhesive film, it can be directly reused. The control module controls the electric telescopic rod 31 on the left to contract, driving the receiving plate 33 to enter the main frame 1, and then controls the air pump to inflate, so that the suction cup 18 releases the glass or back panel to connect the glass and the back panel; the control module controls the third motor 23 to start reverse rotation, release the clamping of the battery cell, and connect the battery cell.

[0060] If the battery cell is intact but has a film, the control module controls the second motor 12 to reverse and drive the connecting block 14 to move left, and controls the fourth motor 34 to start reversing to clean the battery cell again, and then repeats step three, only once. If it is not cleaned, the control module controls the electric telescopic rod 31 in the middle of the right side to retract, driving the receiving plate 33 to enter the main frame 1, and then the control module controls the third motor 23 to start reversing, loosening the clamping of the battery cell to receive the battery cell.

[0061] If the glass and the back panel are intact with adhesive film, the control module controls the first motor 10 to reverse and drive the support block 13 to move left, and clean the glass and the back panel again, and then repeats step three, only once. If it is not cleaned, the control module controls the upper and lower groups of electric telescopic rods 31 on the right to shrink, drive the receiving plate 33 to enter the main frame 1, and then control the air pump to inflate, so that the suction cup 18 releases the glass or the back panel, and the glass and the back panel are connected.

[0062] If the battery cell, glass and back panel are incomplete, the control module controls the right electric telescopic rod 31 to retract, driving the receiving plate 33 to enter the main frame 1, and then controls the air pump to inflate, so that the suction cup 18 releases the glass or back panel to connect the glass and the back panel; the control module controls the third motor 23 to start reverse rotation, releases the clamping of the battery cell, and connects the battery cell.

[0063] A4: The judgment module judges whether the cleaning roller 24 needs to be cleaned, and feeds back to the control module for corresponding operation.

[0064] When m>M, it means that the maximum pressure on the cleaning roller 24 exceeds the maximum allowable pressure, the thickness of the rubber film on the surface of the cleaning roller 24 is too thick, and the cleaning roller 24 needs to be self-cleaned.

[0065] Specifically, after the material is received, the fourth motor 34 of the control module starts to reverse and controls the fifth motor 29 to rotate in the direction opposite to the cleaning roller 24, driving the rotating shaft 27 to rotate, so that the adhesive film on the surface of the cleaning roller 24 is attached to the side of the adhesive removal groove 25 close to the cleaning roller 24. At the same time, the heating wire 28 heats to soften the adhesive film adhered to the surface of the cleaning roller 24, and the fourth motor 34 starts to reverse, and the adhesive removal groove 25 removes the adhesive film adhered to the surface of the cleaning roller 24.

[0066] When m≤M, it means that the maximum pressure on the cleaning roller 24 is normal and self-cleaning is not required.

[0067] Through the above steps, the battery cells are separated from the glass and back panel conveniently and efficiently, which improves the direct reuse rate of the battery cells and reduces the resource consumption when all battery materials are recycled.
