Description

[Technical Field]

[0001] The present invention relates to a recycling method and a recycling system, and more particularly to a recycling method for solar cell panels and a recycling system used therefor. [Background technology]

[0002] In recent years, solar panels, which convert solar energy into electrical energy, have become increasingly important as renewable energy power generation facilities. However, solar panels are discarded when their photoelectric conversion efficiency decreases to a certain level after long-term use. However, in accordance with environmental policies such as resource recovery, energy conservation, and greenhouse gas emission reduction, there is a need to recover or reuse discarded solar panels so that they do not become pollutants to the global environment.

[0003] Patent Document 1 discloses a conventional method for recycling solar cell modules. The solar cell module includes a glass plate, a back sheet, a sealing material, and a plurality of solar cell elements. The plurality of solar cell elements are sandwiched between the glass plate and the back sheet and sealed with the sealing material.

[0004] A conventional method for recycling solar cell modules involves measuring the thickness of the glass plate of a solar cell module that has exceeded its useful life, crushing the glass plate, and separating and recovering the crushed glass fragments and foreign matter.

[0005] The glass plates of solar cell modules are generally tempered glass, which has high recyclability. Therefore, currently, one method for recycling solar cell modules involves decomposing the backsheet and solar cell elements by thermal or chemical methods to avoid damaging the glass plates, and then reusing the glass plates. Another method that is gaining attention is to physically remove the backsheet and solar cell elements, such as by milling or grinding, and then reusing the glass plates.

DETAILED DESCRIPTION OF THE INVENTION

[0013] Hereinafter, a solar cell panel recycling method and a recycling system used therein according to the present invention will be described with reference to the drawings.

[0014] The configuration of a solar cell panel recycling system 200 according to the present invention will be described with reference to Figures 1 to 5. Here, Figure 1 is a block diagram showing the configuration of the solar cell panel recycling system 200 according to one embodiment of the present invention, Figure 2 is a schematic side view showing the configuration of a solar cell panel 3 according to one embodiment of the present invention and the arrangement of a removal device 6 in a solar cell panel recycling method, and Figure 3 is a schematic perspective view showing a state in which a capture device 4 according to one embodiment of the present invention is capturing an image of the solar cell panel 3.

[0015] FIG. 4 is a schematic side view showing a state in which a measuring device 5 according to one embodiment of the present invention is performing dimensional measurement on a solar cell panel 3, and FIG. 5 is a schematic side view showing the arrangement of a removal device 6 according to one embodiment of the present invention.

[0016] As shown in Figures 1 and 2, a solar panel recycling system 200 according to one embodiment of the present invention is configured to perform a collection process on a solar panel 3 placed horizontally on a work surface 900 of a workbench, and is capable of communicating with a back-end server 800 to exchange data.

[0017] In this embodiment, the solar panel 3 includes a cover plate 31, a solar cell unit 32 stacked on the upper surface of the cover plate 31, and a substrate 33 stacked on the upper surface of the solar cell unit 32, as shown in Figure 2.

[0018] As shown in FIG. 2, in this embodiment, the solar cell panel 3 is placed horizontally on the work surface 900 of the work bench so that the cover plate 31, the solar cell unit 32, and the substrate 33 are arranged in order from the bottom (i.e., toward the work bench) to the top.

[0019] As shown in Figure 2, the solar cell unit 32 comprises a plurality of solar cells 321 arranged in an array between the cover plate 31 and the substrate 33 with spaces between them, and an adhesive layer 322 for bonding the cover plate 31, the substrate 33 and the plurality of solar cells 321.

[0020] As shown in Figure 2, the adhesive layer 322 has a bottom portion 3221 that is adhered to the cover plate 31, an upper portion 3222 that is adhered to the substrate 33, and a plurality of intermediate portions 3223 that are connected to the bottom portion 3221 and the upper portion 3222 and fill the gaps between the solar cells 321.

[0021] The cover plate 31 and the adhesive layer 322 are both made of a transparent material, and the substrate 33 is made of an opaque material. In this embodiment, the cover plate 31 is made of glass, and the adhesive layer 322 is an ethylene vinyl acetate (EVA) layer, but the present invention is not limited thereto.

[0022] As shown in FIG. 1, the recycling system 200 of this embodiment includes a capture device 4, a measurement device 5, a removal device 6, and a control device 7 that is electrically connected to the capture device 4, the measurement device 5, and the removal device 6 and can communicate with a back-end server 800 to exchange data.

[0023] In this embodiment, the control device 7 is a computing device such as a personal computer, a laptop, a tablet, or a smartphone, and may have, for example, but is not limited to, a single-core processor, a multi-core processor, a dual-core mobile processor, a microprocessor, a microcontroller, a digital signal processor (DSP), a field-programmable gate array (FPGA), an application specific integrated circuit (ASIC), a radio-frequency integrated circuit (RFIC), etc.

[0024] 3, the solar cell panel 3 is provided with a product label 34. The product label 34 records product information about the solar cell panel 3, and is disposed on the upper surface of the substrate 33.

[0025] The capture device 4 is, for example, a camera, and as shown in Fig. 3, is arranged above the workbench and is controlled by the control device 7 so as to be able to capture an image of the entire solar cell panel 3 downward (i.e., toward the solar cell panel 3). In this embodiment, the capture device 4 can capture an image of the product label 34 as label data.

[0026] As shown in Figures 1 and 4, the measuring device 5 is arranged below the workbench (i.e., below the solar panel 3) and is configured to measure and obtain heights D1 and D3 (described later) through optical measurement technology while moving horizontally relative to the solar panel 3, and is equipped with a first meter 51 and a second meter 52.

[0027] The first meter 51 is configured to be controlled by the control device 7 and to emit a first output of first infrared light upward toward the solar cell panel 3. In this embodiment, the first infrared light is not reflected by the solar cells 321, is completely absorbed by the solar cells 321, or travels toward the substrate 33 through the adhesive layer 322 between two adjacent solar cells 321 and is reflected by the lower surface of the substrate 33.

[0028] The first meter 51 can sense and analyze the first infrared light reflected by the underside of the substrate 33 to measure the height D3 (see Figure 2) from the work surface 900 to the underside of the substrate 33 of the solar panel 3.

[0029] The second meter 52 is configured to be controlled by the control device 7 and to emit a second output of ultraviolet light upward toward the solar cell panel 3. In this embodiment, the ultraviolet light can be reflected by the solar cell panel 3.

[0030] The second measuring instrument 52 can then sense and analyze the ultraviolet light reflected by the solar cell panel 3 to measure the height D1 (see FIG. 2) from the work surface 900 to the upper surface of the cover plate 31 of the solar cell panel 3. Note that the method for measuring the height D1 is not limited to the above, and in other embodiments, the second measuring instrument 52 can measure the height D1 using, for example, sound waves or eddy currents.

[0031] 1, 2, and 5, the removal device 6 is arranged above the solar cell panel 3, and is configured to be controlled by the control device 7 to descend and perform physical removal on the substrate 33 and the solar cell unit 32. Also, as shown in FIGS. 2 and 5, the removal device 6 has a cutting tool 61 for performing physical removal.

[0032] In addition, the removal device 6 is further configured to be able to measure the height D4 (see Figure 2) from the work surface 900 to the top surface of the substrate 33 of the solar panel 3, and the height Z0 (see Figure 2) from the top surface of the substrate 33 to the cutting tool 61.

[0033] In this embodiment, the cutting tool 61 is configured to perform physical removal by milling, but this is not limited thereto, and in other embodiments, the cutting tool 61 can also perform physical removal by, for example, grinding.

[0034] The removal device 6 can measure the height D4 and height Z0 described above using an optical measurement technique. The optical measurement technique involves scanning the upper surface of the substrate 33 and the work surface 900 using, for example, infrared light or laser light. Note that the physical removal method and the method for measuring the heights D4 and Z0 by the removal device 6 are not limited to those described above.

[0035] The method for recycling the solar cell panel 3 according to the present invention will be described below with reference to the drawings.

[0036] The solar cell panel recycling method according to the present invention will be described with reference to Figures 6 and 7. Figure 6 is a flowchart showing the solar cell panel recycling method according to one embodiment of the present invention, and Figure 7 is a schematic side view showing a state in which a removal process is being performed on a solar cell panel 3 in the solar cell panel recycling method according to one embodiment of the present invention.

[0037] A solar cell panel recycling method according to one embodiment of the present invention is carried out by a recycling system 200 for performing recovery processing on the above-described solar cell panel 3, and includes the following steps S11 to S16, as shown in FIG. 6.

[0038] In step S11, as shown in Figures 2 and 6, the solar cell panel 3 is placed horizontally on the work surface 900 of the work bench so that the cover plate 31 faces the work surface 900 and the substrate 33 is above the cover plate 31.

[0039] In step S12, as shown in Figures 3 and 6, the control device 7 controls the capture device 4 to move downward (i.e., toward the solar cell panel 3) to capture the solar cell panel 3 from above the solar cell panel 3 placed on the work surface 900 of the workbench, thereby obtaining an image of the solar cell panel 3, and also controls the capture device 4 to capture an image of the product label 34 attached to the top surface of the substrate 33, thereby obtaining label data from the product label 34.

[0040] In this embodiment, the image of the product label 34 is used as label data, i.e., the label data is in the form of an image. The control device 7 then performs image analysis and character recognition on the image of the product label 34 to obtain product information related to the solar cell panel 3.

[0041] Here, the product information is printed on the product label 34 and includes, but is not limited to, the brand name, model number, and power specifications of the solar panel 3 to be treated.

[0042] In this embodiment, the control device 7 analyzes the image of the solar cell panel 3 to obtain the dimensions of the solar cell panel 3, and determines the treatment area on the solar cell panel 3 based on the dimensions of the solar cell panel 3.

[0043] In some embodiments, one or more junction boxes (not shown) are disposed on the upper surface of the substrate 33 of the solar panel 3. In this case, the control device 7 analyzes an image of the solar panel 3 to obtain data related to the junction boxes, and can provide the data related to the junction boxes to a device for removing the junction boxes before the recycling system 200 of this embodiment physically removes the substrate 33. The data related to the junction boxes includes information on the size and position of each junction box, information on the number of junction boxes, etc. Here, the processing area mentioned above includes an area where one or more junction boxes are disposed.

[0044] 4 and 6, in step S13, while the measuring device 5 is located below the solar cell panel 3 and moves horizontally relative to the solar cell panel 3, the control device 7 controls the first meter 51 of the measuring device 5 to emit first infrared light upward toward the solar cell panel 3, obtain a first measurement result related to the substrate 33, and obtain height D3 based on the first measurement result, and controls the second meter 52 of the measuring device 5 to emit ultraviolet light upward toward the cover plate 31 of the solar cell panel 3, obtain a second measurement result related to the cover plate 31, and obtain height D1 based on the second measurement result. The control device 7 also controls the removal device 6 to measure height D4 and height Z0.

[0045] More specifically, when the first meter 51 emits a first infrared light toward the solar cell panel 3, the first infrared light travels upward through the cover plate 31 to reach the solar cell unit 32, and when the first infrared light hits any solar cell 321, the first infrared light is not reflected by that solar cell 321 and is completely absorbed by that solar cell 321. When the first infrared light travels through the gap between any two adjacent solar cells 321, the first infrared light travels toward the substrate 33, hits the substrate 33, and is reflected by the lower surface of the substrate 33 and is detected by the first meter 51.

[0046] That is, the measuring device 5 obtains the above-mentioned first measurement result by sensing and analyzing the infrared light reflected by the underside of the substrate 33, and obtains the height D3 (see Figure 2) based on the first measurement result.

[0047] Furthermore, when the second meter 52 emits ultraviolet light toward the solar cell panel 3 and the ultraviolet light hits the cover plate 31 of the solar cell panel 3, it is partly absorbed and partly reflected by the cover plate 31 of the solar cell panel 3, and is completely absorbed by the adhesive layer 322 of the solar cell unit 32. The ultraviolet light that is partly reflected by the cover plate 31 is then detected by the second meter 52.

[0048] That is, the measuring device 5 obtains the second measurement result described above by sensing and analyzing the ultraviolet light reflected by the solar cell panel 3, and obtains the height D1 (see Figure 2) based on the second measurement result.

[0049] In this embodiment, the control device 7 controls the measurement device 5 to move horizontally along a diagonal line extending to pass through two opposing corners of any one of the solar cells 321. Here, the measurement device 5 is controlled to pass through at least two solar cells 321. This allows the infrared light to pass through the gap between any one of the solar cells 321.

[0050] The first instrument 51 collects reflection data related to the first infrared light (i.e., the first measurement result described above) and obtains the height D3 based on the reflection data, and the second instrument 52 collects reflection data related to the ultraviolet light (i.e., the second measurement result described above) and obtains the height D1, i.e., the thickness of the cover plate 31, based on the reflection data.

[0051] The reflection data relating to the first infrared light includes at least information relating to the period from when the first instrument 51 emits the first infrared light to when the first instrument 51 senses the first infrared light reflected by the underside of the substrate 33.

[0052] On the other hand, the reflection data related to ultraviolet light includes at least information relating to the period from the time the second instrument 52 emits ultraviolet light to the time the second instrument 52 senses the ultraviolet light reflected by the upper surface of the cover plate 31 (hereinafter also referred to as the first period), and information relating to the period from the time the second instrument 52 emits ultraviolet light to the time the second instrument 52 senses the ultraviolet light reflected by the lower surface of the cover plate 31 (hereinafter also referred to as the second period).

[0053] Here, the second meter 52 is configured to obtain the thickness of the cover plate 31 by calculating the difference between the first period and the second period, or to obtain the height D1 based on the first period.

[0054] In this embodiment, the measuring device 5 is very close to the work surface 900, and there is almost no distance between the measuring device 5 and the work surface 900. However, without being limited to this, in other embodiments, the measuring device 5 is located slightly below the work surface 900, that is, there is a gap between the measuring device 5 and the work surface 900. In this case, the multiple heights obtained by the measuring device 5 can be calibrated by the control device 7. This can ensure that these heights are heights relative to the work surface 900, rather than heights relative to the measuring device 5.

[0055] Furthermore, if there is a gap between the work surface 900 and the solar cell panel 3, the measuring device 5 calibrates the height difference between the work surface 900 and the underside of the cover plate 31 before measuring the dimensions of the solar cell panel 3 (i.e., heights D1 and D3 as shown in FIG. 2, and height D2 described later). Therefore, even if there is a gap between the work surface 900 and the underside of the cover plate 31, the heights D1 to D3 of the solar cell panel 3 can be obtained.

[0056] In step S14, as shown in FIG. 6, the control device 7 obtains the result of the determination as to whether or not an entry of history data corresponding to product information relating to the solar cell panel 3 exists.

[0057] The history data corresponding to the product information related to the solar panel 3 includes a plurality of history parameters used to perform physical removal on the solar panel 3. In this embodiment, the backend server 800 includes a database having a plurality of history data entries corresponding to a plurality of types of solar panel 3, respectively.

[0058] Here, the control device 7 transmits the product information acquired in step S12 to the backend server 800, and the backend server 800 receives the product information and searches a database that has an entry of history data corresponding to the product information.

[0059] Then, the back-end server 800 determines whether or not an entry of history data corresponding to the product information exists in the database, and then transmits the determination result to the control device 7.

[0060] In some embodiments, the control device 7 includes the database described above. The control device 7 can directly search the corresponding database based on the product information acquired in step S12 and determine whether a history data entry corresponding to the product information exists in the database. In this case, the backend server 800 can be omitted.

[0061] If the control device 7 obtains a determination result that there is no history data entry corresponding to the product information related to the solar cell panel 3, the flow proceeds to step S15, i.e., the control device 7 performs the first processing procedure described below.

[0062] In contrast, if the control device 7 obtains a determination result that there is a history data entry corresponding to the product information related to the solar cell panel 3, the flow proceeds to step S16, i.e., the control device 7 performs the second processing procedure described below.

[0063] In step S15, a first processing procedure is performed as shown in Fig. 6. Here, the first processing procedure performs the following: The control device 7 acquires a first removal parameter related to the substrate 33 and a second removal parameter related to the cover plate 31 based on the heights D1 and D3 (see Fig. 2) described above, using the upper surface of the substrate 33 as a reference surface (i.e., the height of the upper surface of the substrate 33 is set to zero).

[0064] Next, based on the first removal parameter and the second removal parameter, the control device 7 controls the cutting tool 61 to descend to the upper surface of the substrate 33, which is set as the reference plane according to the above-mentioned height Z0 (see Figure 2), and move in the processing area determined in step S12 to perform physical removal on the substrate 33 and the solar cell unit 32 in the solar cell panel 3.

[0065] 2 and 7, the control device 7 controls the cutting tool 61 to physically remove a portion of the solar cell panel 3 that is higher than the height D3 relative to the work surface 900, i.e., to physically remove the substrate 33, based on the first removal parameter, to obtain a first remaining portion 301. The first remaining portion 301 includes the cover plate 31 and the solar cell unit 32.

[0066] Then, based on the second removal parameter, the control device 7 controls the removal device 6 to physically remove a portion of the first remaining portion 301 that is higher than the height D1 relative to the work surface 900, i.e., physically remove the solar cell unit 32, to obtain a second remaining portion 302 that has at least the cover plate 31. In reality, the second remaining portion 302 includes not only the cover plate 31 but also a remaining portion of the bottom 3221 of the adhesive layer 322 that is adhered to the cover plate 31, as shown in FIG.

[0067] In this embodiment, the first removal parameter indicates a first distance that the cutting tool 61 descends relative to the top surface of the substrate 33. The first distance is the difference between the height D4 and the height D3, as shown in FIG.

[0068] In other words, the first removal parameter is obtained based on heights D4 and D3, and is a negative value indicating a first distance downward from the top surface of substrate 33, which is the reference plane. Thus, as shown in Fig. 7, the control device 7 controls the cutting tool 61 to descend from the top surface of substrate 33 by the first distance equal to the absolute value of the first removal parameter to physically remove a part of the solar cell panel 3, i.e., the cover plate 31.

[0069] On the other hand, the second removal parameter indicates a second distance that the cutting tool 61 descends relative to the upper surface of the substrate 33. The second distance is the difference between the height D4 and the height D1, as shown in FIG.

[0070] In other words, the second removal parameter is obtained based on heights D4 and D1, and is a negative value indicating a second distance downward from the top surface of substrate 33, which is the reference plane. Thus, as shown in Fig. 7, control device 7 controls cutting tool 61 to descend a second distance equal to the absolute value of the second removal parameter from the top surface of substrate 33 or a level corresponding to the first distance, thereby physically removing part of first remaining portion 301, i.e., solar cell unit 32.

[0071] In this embodiment, the second remaining portion 302 includes at least the cover plate 31, and also includes a portion of the adhesive layer 322. One reason why a portion of the adhesive layer 322 is left in the second remaining portion 302 is that if the cutting tool 61 comes into direct contact with the cover plate 31, the cover plate 31 will be easily damaged and will not be able to be retrieved.

[0072] To avoid such problems, the second removal parameters are generally set so that the cutting tool 61 can remove most of the solar cell unit 32 without contacting the cover plate 31. Thus, a portion of the adhesive layer 322 remains on the upper surface of the cover plate 31.

[0073] Another reason why a portion of the adhesive layer 322 is left in the second remaining portion 302 is that when the cover plate 31 obtained by the above-mentioned removal process is transported, there is a possibility that the cover plate 31 may be damaged, and to prevent such a situation, the portion of the adhesive layer 322 left on the upper surface of the processed cover plate 31 is used as a protective component.

[0074] In the first processing procedure, the control device 7 further controls the capture device 4 to capture the upper surface of the first remaining portion 301 to obtain a first image showing the state in which the substrate 33 has been removed, and to capture the upper surface of the second remaining portion 302 to obtain a second image showing the state in which the cover plate 31 remains.

[0075] Then, the control device 7 analyzes the difference between the above-mentioned first image and the image of the solar cell panel 3 to obtain results related to the physical removal of a portion of the solar cell panel 3, and analyzes the difference between the above-mentioned second image and the first image to obtain results related to the physical removal of a portion of the first remaining portion 301.

[0076] Here, after a portion of the solar cell panel 3 has been physically removed, i.e., after the solar cell panel 3 has become the first remaining portion 301, when the substrate 33 is completely removed from the solar cell panel 3, the upper surface of the first remaining portion 301 appears dark gray.

[0077] In contrast, if the substrate 33 is not completely removed from the solar cell panel 3, a portion of the upper surface of the first remaining portion 301 will be white. In this case, the control device 7 analyzes the white portion in the first image showing the state in which the substrate 33 has been removed, and obtains a result related to the physical removal of a portion of the solar cell panel 3.

[0078] Similarly, after a portion of the first remaining portion 301 has been physically removed, i.e., after the first remaining portion 301 has become the second remaining portion 302, when the solar cell 321 is completely removed from the solar panel 3, the upper surface of the second remaining portion 302 appears gray.

[0079] In contrast, if the solar cell 321 is not completely removed from the solar cell panel 3, a portion of the upper surface of the second remaining portion 302 will appear black. In this case, the control device 7 analyzes the black portion in the second image showing the state in which the cover plate 31 remains, and obtains a result related to the physical removal of a portion of the first remaining portion 301.

[0080] Then, the control device 7 creates process data related to the removal (hereinafter also referred to as first process data), and the first process data corresponds to the solar panel 3 and includes at least the first removal parameter and the second removal parameter.

[0081] In some embodiments, in order to calibrate and optimize the first removal parameters and second removal parameters that may be used in the future, the first process data created in the first processing procedure further includes the first and second images described above, results associated with the physical removal of a portion of the solar panel 3, and results associated with the physical removal of a portion of the first remaining portion 301.

[0082] In addition, the control device 7 associates the first process data corresponding to the solar panel 3 with product information related to the solar panel 3, and transmits the product information and the first process data associated with the product information to the backend server 800.

[0083] Then, the backend server 800 can store the first process data associated with the product information as an entry of the history data corresponding to the product information of the solar cell panel 3.

[0084] In some embodiments in which the database is included in the control device 7, the control device 7 can directly store the product information for the solar panel 3 and the first process data associated with the product information as entries of historical data corresponding to the product information for the solar panel 3.

[0085] The history parameters in the entries of the history data stored in this manner include a first history parameter which is a first removal parameter from the first process data corresponding to the solar panel 3, and a second history parameter which is a second removal parameter from the first process data corresponding to the solar panel 3.

[0086] As described above, if the above-mentioned judgment result is that there is a history data entry (hereinafter also referred to as reference data) corresponding to the product information related to the solar cell panel 3, the control device 7 performs the second processing procedure, i.e., the flow proceeds to step S16.

[0087] In this case, this means that a solar panel with the same specifications as the solar panel 3 to be processed has already been processed by the recycling system 200 of this embodiment, and the associated process data has already been stored in a database in the backend server 800 or the control device 7.

[0088] In step S16, a second processing procedure is performed as shown in Fig. 6. Here, the second processing procedure performs the following: That is, the control device 7 acquires a first removal parameter related to the substrate 33 and a second removal parameter related to the cover plate 31 based on the heights D1 and D3 (see Fig. 2) described above, using the upper surface of the substrate 33 as a reference plane.

[0089] Here, the means for acquiring the first and second elimination parameters are the same as those in the first processing procedure in step S15, and therefore, for the sake of brevity, redundant explanations will be omitted.

[0090] The control device 7 analyzes the difference between the first removal parameter and the first history parameter based on the reference data, and the difference between the second removal parameter and the second history parameter based on the reference data.

[0091] The first historical parameter and the second historical parameter are stored in the reference data and are parameters used to process a solar panel with the same specifications as the previously processed solar panel 3.

[0092] When the control device 7 determines that the difference between the first removal parameter and the first history parameter is greater than the first threshold, it selects the first removal parameter, and when the control device 7 determines that the difference between the first removal parameter and the first history parameter is smaller than the first threshold, it selects the first history parameter.

[0093] Similarly, when the control device 7 determines that the difference between the second removal parameter and the second history parameter is greater than the second threshold, it selects the second removal parameter, whereas when the control device 7 determines that the difference between the second removal parameter and the second history parameter is smaller than the second threshold, it selects the second history parameter. Note that the first threshold and the second threshold may be the same or different from each other.

[0094] In the second processing procedure, the control device 7 causes the cutting tool 61 to descend to the upper surface of the substrate 33, which is used as the reference surface, according to the height Z0 as shown in Figure 2, and move within the processing area determined in step S12 to perform physical removal on the substrate 33 according to the selected first removal parameter or first history parameter, and also performs physical removal on the solar cell unit 32 according to the selected second removal parameter or second history parameter.

[0095] More specifically, based on the selected first removal parameter or first history parameter, the control device 7 controls the cutting tool 61 to descend from the top surface of the substrate 33 a distance (third distance) equal to the absolute value of the selected first removal parameter or first history parameter to physically remove a portion of the solar cell panel 3 (i.e., a portion of the solar cell panel 3 that is higher than height D3 relative to the working surface 900).

[0096] Based on the selected second removal parameter or second history parameter, the control device 7 further controls the cutting tool 61 to descend from the top surface of the substrate 33 a distance (fourth distance) equal to the absolute value of the selected second removal parameter or second history parameter to physically remove a portion of the first remaining portion 301 (i.e., a portion of the first remaining portion 301 that is higher than height D1 relative to the work surface 900).

[0097] In the second processing procedure, the control device 7 further controls the capture device 4 to capture the upper surface of the first remaining portion 301 to obtain a first image showing the state in which the substrate 33 has been removed, and to capture the upper surface of the second remaining portion 302 to obtain a second image showing the state in which the cover plate 31 remains.

[0098] Then, the control device 7 analyzes the difference between the above-mentioned first image and the image of the solar cell panel 3 to obtain results related to the physical removal of a portion of the solar cell panel 3, and analyzes the difference between the above-mentioned second image and the first image to obtain results related to the physical removal of a portion of the first remaining portion 301.

[0099] Furthermore, the control device 7 creates process data related to the removal (hereinafter also referred to as second process data), which corresponds to the solar panel 3 and includes at least the selected first removal parameter or first history parameter and the selected second removal parameter or second history parameter.

[0100] In some embodiments, the second process data generated in the second processing procedure further includes the first and second images described above, results associated with the physical removal of a portion of the solar panel 3, and results associated with the physical removal of a portion of the first remaining portion 301.

[0101] In addition, the control device 7 associates the second process data corresponding to the solar panel 3 with product information related to the solar panel 3, and transmits the product information and the second process data associated with the product information to the backend server 800.

[0102] Then, the backend server 800 updates the history data entry stored in the database of the backend server 800 based on the second process data associated with the product information. That is, the second process data added to the history data entry is currently the most recently stored data in the history data entry and is available for use in the second processing procedure.

[0103] In some embodiments in which the database is included in the control device 7, the control device 7 can directly update the historical data entries stored in the control device 7 database based on the second process data associated with the product information.

[0104] As described above, in this embodiment, the control device 7 performs the recovery process using the upper surface of the substrate 33 as the reference plane. Note that in some embodiments, the control device 7 uses the work surface 900 as the reference plane, i.e., the height of the work surface 900 is set to zero. In this case, steps S15 and S16 are performed as follows.

[0105] In the first processing procedure of step S15, the control device 7 acquires a first removal parameter and a second removal parameter based on the heights D1 and D3 (see FIG. 2) using the work surface 900 as a reference surface.

[0106] Next, based on the first removal parameter and the second removal parameter, the control device 7 controls the cutting tool 61 to move in the processing area determined in step S12 and perform physical removal on the substrate 33 and the solar cell unit 32 in the solar cell panel 3.

[0107] Here, the first removal parameter indicates a first height (i.e., a height equal to the height D3) calculated from the work plane 900 at which the cutting tool 61 should be when performing the removal process on a portion (i.e., the substrate 33) of the solar panel 3. In other words, the first removal parameter is a positive value indicating a first height upward from the reference plane.

[0108] On the other hand, the second removal parameter indicates a second height (i.e., a height equal to the height D1) calculated from the work plane 900 at which the cutting tool 61 should be located when performing the removal process on the part of the first remaining portion 301 (i.e., the solar cell unit 32). In other words, the second removal parameter is a positive value indicating a second height above the reference plane.

[0109] Based on the first removal parameter, the control device 7 controls the cutting tool 61 to descend from above the solar cell panel 3 toward the work surface 900 to a first level, which is a first height calculated from the work surface 900, to physically remove a portion of the solar cell panel 3.

[0110] Then, based on the second removal parameter, the control device 7 controls the cutting tool 61 to descend from the first level toward the working surface 900 to a second level, which is a second height calculated from the working surface 900, to physically remove a portion of the first remaining portion 301.

[0111] In the second processing procedure of step S16, the control device 7 acquires the first removal parameter and the second removal parameter based on the heights D1 and D3, using the work surface 900 as the reference surface.

[0112] The control device 7 analyzes the difference between the first removal parameter and the first historical parameter based on the historical data, and the difference between the second removal parameter and the second historical parameter based on the historical data.

[0113] Next, the control device 7 selects the first removal parameter or the first history parameter based on the difference between the first removal parameter and the first history parameter based on the history data and the first threshold value, and selects the second removal parameter or the second history parameter based on the difference between the second removal parameter and the second history parameter based on the history data and the second threshold value.

[0114] Then, based on the selected first removal parameter or first history parameter, the control device 7 controls the cutting tool 61 to descend from above the solar cell panel 3 toward the work surface 900 to a third level, which is a first height calculated from the work surface 900 (i.e., a height equal to height D3 as shown in Figure 2), and physically remove a part of the solar cell panel 3 (i.e., the substrate 33).

[0115] Based on the selected second removal parameter or second history parameter, the control device 7 controls the cutting tool 61 to descend from the third level toward the work surface 900 to a fourth level, which is a second height calculated from the work surface 900 (i.e., a height equal to height D1 as shown in Figure 2), to physically remove a portion of the first remaining portion 301 (i.e., the solar cell unit 32).

[0116] In some embodiments, the first meter 51 of the measuring device 5 is controlled by the control device 7 to emit a second infrared light of a third output upward toward the solar panel 3 to measure the height D2 (see Figure 2) from the work surface 900 to the underside of any one of the solar cells 321 in the solar panel 3.

[0117] Here, the third output is set so that the second infrared light is not completely absorbed by the solar cell 321, that is, so that the second infrared light is partially absorbed and partially reflected by the solar cell 321.

[0118] The second infrared light may travel toward the substrate 33 through the gap between any one of the solar cells 321 and be reflected by the lower surface of the substrate 33, but the luminous flux of the second infrared light reflected by the lower surface of the substrate 33 is outside the measurable range of the first meter 51. It should be noted that the third output of the second infrared light is greater than the first output of the first infrared light.

[0119] In this case, in step S13, the control device 7 further controls the first instrument 51 to emit the second infrared light upward toward the solar cell panel 3 while moving horizontally, and acquire a measurement result related to the solar cell 321. Then, the measurement device 5 acquires the height D2 described above based on the measurement result related to the solar cell 321.

[0120] In addition, the measurement results related to the solar cell 321 include at least information relating to the period from the time when the first instrument 51 emits the second infrared light to the time when the first instrument 51 senses the second infrared light reflected by the underside of the solar cell 321.

[0121] More specifically, when the first instrument 51 emits the second infrared light toward the solar cell panel 3 , the second infrared light travels upward to reach the solar cell unit 32 through the cover plate 31 .

[0122] Here, since the third output of the second infrared light is higher than the first output of the first infrared light and the second infrared light is not completely absorbed by the solar cells 321, when the second infrared light hits any solar cell 321, the second infrared light is partly absorbed and partly reflected by that solar cell 321. Then, the second infrared light partly reflected by the solar cell 321 is sensed by the first instrument 51.

[0123] Furthermore, when the second infrared light travels through the gap between any two solar cells 321 toward the substrate 33 , the second infrared light hits the lower surface of the substrate 33 and is reflected by the lower surface of the substrate 33 .

[0124] In this embodiment, the second infrared light reflected by the lower surface of the substrate 33 is outside the measurable range of the first instrument 51 and is considered as noise by the first instrument 51. In other words, the first instrument 51 can sense only a portion of the second infrared light reflected by the solar cell 321.

[0125] In this embodiment, the control device 7 obtains a first removal parameter associated with the substrate 33 based on the height D1 and the height D3, and a second removal parameter associated with the cover plate 31 based on the height D1, the height D3, and the height D4.

[0126] In some embodiments, the control device 7 obtains a second removal parameter further based on the height D2 and optimizes the second removal parameter to leave a portion of the adhesive layer 322 on the upper surface of the cover plate 31 as a buffer layer.

[0127] More specifically, the second removal parameter is a parameter for performing physical removal on a part of the solar cell unit 32 that is higher than the intermediate height between the height D1 and the height D2.

[0128] In this embodiment, the product label 34 is a sticker on which product information is attached to the solar panel 3. The capture device 4 (for example, a camera) captures an image of the product label 34 using image capture technology, and the control device 7 analyzes the image of the product label 34 to obtain product information related to the solar panel 3.

[0129] In some embodiments, the product label 34 is a wireless tag containing label data, and the capture device 4 reads the wireless tag via wireless communication technology to obtain the label data.

[0130] Here, the wireless tag may be a radio frequency identification tag (RFID tag), a near field communication tag (NFC tag), a two-dimensional barcode, or the like.

[0131] The capture device 4 has a reader (e.g., a radio frequency identification reader, a near field communication reader, or a barcode reader) for reading the wireless tag via wireless communication technology, and can thereby acquire the label data encoded on the wireless tag. The acquired label data includes a unique identifier for the solar panel 3 and further includes product information for the solar panel 3.

[0132] The backend server 800 or the control device 7 can store multiple product information, each corresponding to a different unique identifier, representing a different type, variety, or specification of the solar panel 3.

[0133] If the label data includes only the unique identifier of the solar panel 3 to be processed, the control device 7 acquires the unique identifier from the capture device 4. Then, the backend server 800 or the control device 7 can acquire product information of the solar panel 3 according to the unique identifier thus acquired. Note that, without being limited thereto, in some embodiments, the label data includes the unique identifier and product information of the solar panel 3, and the control device 7 can acquire product information of the solar panel 3 by directly reading the label data.

[0134] Therefore, in some embodiments, in step S12, the control device 7 not only captures an image of the solar panel 3, but also controls the capture device 4 to read the product label 34 via wireless communication technology to obtain the label data encoded on the product label 34, and the backend server 800 or the control device 7 can obtain product information related to the solar panel 3 according to the label data.

[0135] In summary, the solar panel recycling method and recycling system 200 of the present invention can automatically determine whether or not a history data entry corresponding to the solar panel 3 collected by the recycling system 200 exists in the backend server 800 or the control device 7.

[0136] If there is no history data entry corresponding to the solar cell panel 3, the recycling system 200 automatically performs removal and recovery on the substrate 33 based on the first removal parameters, performs removal and recovery on the solar cell unit 32 based on the second removal parameters, recovers the entire cover plate 31, and associates the process data entry related to the removal with the product information for the solar cell panel 3, and stores the removal process entry in the backend server 800 or the control device 7 as a history data entry corresponding to the solar cell panel 3.

[0137] If a history data entry corresponding to the solar cell panel 3 exists, the recycling system 200 determines to select a first removal parameter or first history parameter and to select a second removal parameter or second history parameter, and automatically performs removal or recovery on the substrate 33 based on the selected first removal parameter or first history parameter, performs removal or recovery on the solar cell unit 32 based on the selected second removal parameter or second history parameter, recovers the entire cover plate 31, and associates the process data entry related to the removal with product information for the solar cell panel 3, and updates the history data entry corresponding to the solar cell panel 3 that may be used in the future in the backend server 800 or the control device 7 based on the process data related to the removal.

[0138] That is, the solar panel recycling method and system 200 according to the present invention can automatically create and update multiple history data entries, each corresponding to a different type, variety, or standard of solar panel 3. These history data entries can then be used as reference data to guide the recovery process for solar panel 3 of the same type.

[0139] Thus, the solar panel recycling method and system 200 of the present invention can improve the efficiency of the recycling process and the purity of the recycled materials by automatically accommodating different types, varieties, and specifications of solar panels using appropriate removal parameters.

[0140] Although numerous specific details are set forth above to provide a thorough understanding of the present invention, it will be apparent to one skilled in the art that one or more other embodiments may be practiced without these specific details.

[0141] While the preferred embodiments and variations of the present invention have been described above, the present invention is not limited to these and encompasses all modifications and equivalents as various configurations falling within the spirit and scope of the broadest interpretation. [Industrial Applicability]

[0142] The solar panel recycling method and system according to the present invention can improve the efficiency of the recycling process and the purity of the recycled materials by automatically adapting to different types, varieties, and specifications of solar panels using appropriate removal parameters, and thus has industrial applicability.
