Description

[0001] Cross - reference to related applications

[0002] This application claims the priority of Taiwan Patent Application No. 111115315 filed on April 21, 2022, which is incorporated herein by reference for all purposes as if fully set forth herein. Technical field

[0003] The utility model relates to a solar module recycling device, in particular to a grinding - type solar module recycling device. Background art

[0004] Solar module recycling devices are divided into chemical recycling and physical recycling. Currently, chemical recycling is mainly used. However, the waste liquid generated after chemical recycling will cause secondary environmental pollution, and there is still no real environmental protection benefit. Moreover, the recovery rate of available materials is low, which is not conducive to subsequent utilization.

[0005] Many manufacturers have proposed relevant patents for physical recycling devices. As shown in FIGS. 7(a) and (b) of the utility model patent of Japanese Laid - Open No. JP2011173099A, the outer layer of the solar module is first broken, and then a single blade with the same width as the solar module is used to scrape the broken outer layer from its contact surface with the lower layer to recover irregular fragments.

[0006] Another example is the utility model patent of Korean Patent Publication No. KR102091346B1 Figure 3 and FIG. 4. In this utility model patent, with a double - blade cutter head, a first blade is used to first cut a long groove on the outer layer of the solar module to define a strip area, and then a second blade with the same width as the strip area is used to scrape the strip area from its contact surface with the lower layer to recover the strip.

[0007] Another example is the invention patent disclosed in No. TW202132171A Figure 2 As shown, this invention patent cooperates with a heating table, first heats the solar module, then uses a pre - cutting device to first cut a cutting part on its battery layer, and then uses the blade part of a scraping die to cut off the solar cell layer.

[0008] The above three patents all use tools for physical recycling of solar modules. Although it does not produce secondary - pollution waste liquid compared with chemical recycling, since the solar module is a laminated structure, in the scraping - type recycling, the recycled materials are easily mixed with materials of different layers, and the recycling accuracy is not high. It must be refined before it can be used, and the overall recycling efficiency is not good. Therefore, it is necessary to further improve it. Summary of the utility model

[0009] In view of the above-listed disadvantages of the physical solar module recycling equipment, the main object of the present utility model is to provide a grinding-type solar module recycling equipment.

[0010] The main technical means used to achieve the above object is to make the grinding-type solar module recycling equipment include:

[0011] A platform having a solar module placement area;

[0012] A grinding tool disposed above the platform and moving relative to the solar module placement area; and

[0013] A negative pressure collector disposed above the platform to collect grinding powder by negative pressure; wherein the grinding tool and the negative pressure suction head are fixed in the same housing.

[0014] From the above description, the advantages of the present utility model are as follows:

[0015] The present utility model mainly uses a grinding tool to grind the solar module layer by layer, and the powder generated by grinding different layers of the solar module is quickly collected separately through the negative pressure suction head of the negative pressure collector; thus, the grinding-type solar module recycling equipment of the present utility model not only does not generate secondary pollutants, but also the purity of the powdered recycled material is high, which is convenient for subsequent utilization.

[0061] The present utility model provides a physical solar module recycling device, and the technical content is described in detail below with multiple embodiments and diagrams.

[0062] First, please refer to Figure 1 As shown, the grinding - type solar module recycling device 1 of the present utility model includes a platform 10, a grinding tool 20, and a negative - pressure collector 30; wherein the platform 10 is used for placing a solar module 60 thereon, and both the grinding tool 20 and the negative - pressure collector 30 are arranged on the platform 10 to move relative to the solar module 60 on the platform 10; preferably, the grinding tool 20 and the negative - pressure collector 30 are controlled by a three - axis moving device 40 fixed on the platform 10 to perform three - axis movement, the grinding tool 20 grinds the solar module 60 layer by layer, and the negative - pressure collector 30 quickly recovers the powders generated by grinding different layers of the solar module 60 separately.

[0063] Please refer to in conjunction with Figure 2 and Figure 6As shown, the above-mentioned platform 10 has a solar module placement area 100 for placing the solar module 60 thereon. In this embodiment, the platform 10 further includes a plurality of locators 11. The locators 11 are arranged on the side of the solar module placement area 100 to fix the solar module 60 thereon. In one implementation, each locator 11 is an electrically controlled fixture, which includes a rotary cylinder and a fixture. After being electrically controlled, the rotary cylinder controls the fixture to rotate relative to the side of the solar module placement area 100, and can then be rotated into the solar module placement area 100 or rotated away from the solar module placement area 100 for fixing the solar module 60 on the solar module placement area 100.

[0064] Please refer to Figure 2 and Figure 6 As shown, the above-mentioned grinding tool 20 and the three-axis moving device 40 are both arranged on the platform 10. The grinding tool 20 can be composed of a plurality of blades. In this embodiment, as Figure 2 shown, the three-axis moving device 40 includes two Y-axis slide groups 41, an X-axis slide group 42, a Z-axis slide group 43, a Y-axis motor 44, an X-axis motor 45 and a Z-axis motor 46. The two Y-axis slide groups 41 are respectively arranged on two opposite sides of the platform 10 parallel to the Y-axis. The Y-axis motor 44 is fixed on one side of the platform 10 parallel to the X-axis, and can connect the two Y-axis slide groups 41 through a steering gear 441 to synchronously control the movement of the two Y-axis slide groups 41. The X-axis slide group 42 is arranged on the two Y-axis slide groups 41 to move along the Y-axis. The X-axis motor 45 is fixed thereon to control the movement of the X-axis slide group 42. The Z-axis slide group 43 is arranged on the X-axis slide group 42 to move along the X-axis, and the grinding tool 20 is fixed on the Z-axis slide group 43. The Z-axis motor 46 is fixed thereon to control the movement of the Z-axis slide group 43, so that the grinding tool 20 moves along the Z-axis. Therefore, the grinding tool 20 can adjust its XY plane position (plane position) relative to the platform 10 through the X-axis motor 45 and the Y-axis motor 44, and can adjust its Z-axis position (height position) relative to the platform 10 through the Z-axis motor 46. However, the setting method of this three-axis moving device 40 is not limited to the above-mentioned utility model. As long as the grinding tool 20 can be moved in the XYZ three axial directions relative to the platform 10, it can be used as the three-axis moving device 40 in this case.

[0065] Please refer to Figure 2 and Figure 3 As shown, the above-mentioned negative pressure collector 30 is arranged on the platform 10 to suck the powder ground by the grinding tool 20 on the solar module 60 by the negative pressure collector 30. In this embodiment, as Figure 2 and Figure 3As shown, the negative pressure collector 30 includes a negative pressure suction head 31, a pipe component group 32, and a pump 33. The negative pressure suction head 31 is communicated with the pump 33 through the pipe component group 32, and the pump 33 is further communicated with at least one recovery cylinder 34. In one embodiment, the negative pressure suction head 31 can be further disposed on one side of the grinding tool 20 together, such as Figure 4A As shown, the grinding tool 20 and the negative pressure suction head 31 are disposed in the same housing 21. Thus, when the grinding tool 20 moves relative to the platform 10 through the three-axis moving device 40, the negative pressure suction head 31 can move in conjunction to synchronously suck the powder ground and cut by the grinding tool 20, preventing the dust from floating around. Again, such as Figure 4B and Figure 4C As shown, two flat pressing wheels 311 can be further respectively disposed on two opposite sides of the housing 21 corresponding to the negative pressure suction head 31 to prevent the negative pressure from wrinkling the ground and thinned solar module 60. Preferably, the flat pressing wheel 311 is a universal wheel. In another embodiment, the negative pressure collector 30 can include a plurality of recovery cylinders 34 corresponding to different material layers of the solar module 60. In Figure 3 Another embodiment of the grinding type solar module recovery device 1a shown, that is, compared with Figure 2 the grinding type solar module recovery device 1 shown is disposed in an operation room 12, and the pipe component group 32 and the pump 33 of the negative pressure collector 30 and at least one recovery cylinder 34 can be all disposed outside the operation room 12.

[0066] Please refer to Figure 5 As shown, the grinding type solar module recovery device 1 of the present utility model further includes an electric control system 50. The electric control system 50 at least includes a computer unit 51, a control interface 511, and a database 52. The computer unit 51 is electrically connected to the plurality of positioners 11 of the platform 10, the grinding tool 20, the Y-axis motor 44, the X-axis motor 45, and the Z-axis motor 46 of the three-axis moving device 40, and the pump 33 through the control interface 511. The database 52 stores data of the solar module 60, including dimensions, material layer information (such as number of layers, layer thickness, material properties, etc.), manufacturers, product barcodes, etc. The database 52 sets and stores a grinding path corresponding to different solar modules 60. The grinding path is at least determined by the dimensions, number of layers, and layer thickness of the solar module 60 to achieve fully automatic and completely precise grinding. In addition, the computer unit 51 is further electrically connected to a display 53 and an input unit 54 to display an operation interface and establish the data stored in the database 52. Also, the input unit 54 can include a barcode scanner to scan the product barcode of the solar module, and the computer unit 51 quickly reads the data of the same solar module 60 to perform the grinding and recovery operation.

[0067] Please continue to refer to Figure 6 and FIG. 7. When a solar module 60 is placed in the solar-module placement area 100 of the platform 10, the positioner 11 of the platform 10 will be controlled by the computer unit 51 of the electric control system 50 to screw into the solar-module placement area 100 to clamp and fix the solar module 60 on the platform 10. The data of the solar module 60 can be read from the database 52 of the electric control system 50 by scanning or inputting the product bar code of the solar module 60 to determine the grinding path of the grinding tool 20. As Figure 6 shown, the grinding tool 20 travels according to the grinding path, and the position of the positioner 11 will be marked on the grinding path. Therefore, before the grinding tool 20 approaches any positioner 11, the positioner 11 will be controlled to screw out of the solar-module placement area 100 to facilitate the passage of the grinding tool 20, and then screw into the solar-module placement area 100 after passing through to ensure that the current material layer of the solar module 60 is completely ground. Since the material properties of the material layers are different, the computer unit 51 will set the depth and number of grinding times of the grinding tool 20 according to the grinding tool 20. Since the grinding depth can be accurately controlled, complete and accurate grinding can be achieved.

[0068] Assume that the currently placed solar module 60 has five material layers, and two of them are the same material layers. Four recovery cylinders 34 can be prepared and matched with four air valves 331 in the pipe fitting group 32 shown in Figure 3 to be selectively communicated. The multiple air valves 331 are controlled to open and close by the computer unit 51 through the control interface 511, so that the pipe fitting group 32 is selectively communicated with a specific recovery cylinder 34. As Figure 7A shown, first, the grinding tool 20 grinds the first material layer 61 of the solar module 60. The powder ground from the first material layer 61 can be immediately sucked by the negative-pressure suction head 31 and stored in the recovery cylinder A. After the first material layer 61 is ground, as Figure 7B shown, the computer unit 51 then controls the grinding tool 20 to rotate to grind the second material layer 62. The powder ground from the second material layer 62 can be immediately sucked by the negative-pressure suction head 31 and stored in the recovery cylinder B. After the second material layer 62 is ground, as Figure 7C shown, the computer unit 51 then controls the grinding tool 20 to grind the third material layer 63. The powder ground from the third material layer 63 can be immediately sucked by the negative-pressure suction head 31 and stored in the recovery cylinder C. After the third material layer 63 is ground, as Figure 7DAs shown, the computer unit 51 then controls the grinding tool 20 to grind the fourth material layer 64. Since the fourth material layer 64 is the same as the second material layer 62, the powder obtained by grinding the fourth material layer 64 can be immediately sucked by the negative pressure suction head 31 and stored in the recovery cylinder B. After the fourth material layer 64 is ground, as Figure 7E shown, the computer unit 51 then controls the grinding tool 20 to grind the fifth material layer 65. The powder obtained by grinding the fifth material layer 65 can be immediately sucked by the negative pressure suction head 31 and stored in the recovery cylinder D; thus, the solar module 60 is completely ground and recovered, and no waste materials or waste liquids are generated.

[0069] As Figure 5 shown, the computer unit 51 is connected to at least one three-dimensional scanning component 13 (such as an optical scanner, a sound wave scanner, etc.). The three-dimensional scanning component 13 is disposed on the platform 10 to scan the three-dimensional space of the solar module placement area 100 of the platform 10, that is, the surface profile of the solar module 60 can be scanned, and a three-dimensional surface profile pattern of the solar module 60 placed on the platform 10 can be obtained; in an embodiment, as Figure 8 shown, two three-dimensional scanning components 13 can be used and respectively disposed at two diagonal positions of the solar module placement area 100 to comprehensively scan the surface profile of the solar module. Therefore, the computer unit 51 can obtain the three-dimensional surface profile pattern and judge and calculate the position of the protrusion and the thickness change; when the computer unit 51 controls the grinding tool 20 to grind according to the grinding path and reaches the position of the protrusion 600, the grinding tool 20 will rise and fall correspondingly according to the calculated thickness change of the protrusion 600. In this way, it can be ensured that when grinding a specific material layer with the protrusion 600, the powder of the material layer can be completely recovered, and it will not be the case that due to a fixed grinding height, the grinding tool grinds to the next material layer, resulting in the mixing and impurity of the recovered powder. It should be noted that Figure 8 is a combined view of two figures. Among them, the part showing the platform 10, the solar module placement area 100 and the three-dimensional scanning component 13 is a top plan view of another embodiment of the grinding type solar module recovery device of the present invention; the part only showing the protrusion 600 is a side plan view of the solar module 60 in another embodiment of the grinding type solar module recovery device of the present invention; the dashed line between the two indicates the corresponding position relationship of the protrusion 600.

[0070] In summary, the recycling equipment for the grinding-type solar module of the present utility model mainly uses grinding tools, and the grinding tools and the negative pressure suction head are fixed in the same housing. When grinding the solar module layer by layer, the powders generated by grinding different layers of the solar module are quickly collected separately through the negative pressure suction head of the negative pressure collector. Thus, the recycling equipment for the grinding-type solar module of the present utility model not only does not generate secondary pollutants, but also has a high purity of the powdered recycled material, which is convenient for subsequent utilization.
