Description

Technical Field

[0001] This invention relates to an identification and measurement system, and more particularly to an identification and measurement system for identifying the model and measuring the specifications of solar cell modules. Background Technology

[0002] Solar cell modules are among the most common green energy devices. To prevent discarded solar cell modules from becoming sources of environmental pollution, many companies have begun investing in the recycling and processing of discarded solar cell modules, attempting to turn them into reusable renewable resources. Currently, in addition to chemical or heating methods to decompose and recycle materials, another noteworthy material recycling method is the physical processing method of milling or grinding the solar cell modules.

[0003] A solar cell module generally includes a solar cell body for photoelectric conversion, a frame surrounding the solar cell body, and a junction box located on the back of the solar cell body. The solar cell body itself consists of a backplate, a cover plate, and multiple photovoltaic panels fixed between the backplate and the cover plate by adhesive layers. However, because there are currently over 17,000 different types of solar cell modules worldwide, accurately obtaining product specification data, length and width dimensions, junction box location data, and the thickness of each layer of the solar cell body before recycling is a pressing problem for recycling companies. Summary of the Invention

[0004] The purpose of this invention is to provide an identification and measurement system for solar cell modules that can improve upon at least one drawback of the prior art.

[0005] This invention relates to an identification and measurement system for solar cell modules, suitable for identifying the specifications and measuring the dimensions of solar cell modules awaiting recycling. The solar cell module includes a solar cell body and a product label affixed to the solar cell body.

[0006] The identification and measurement system includes a housing mechanism, a support mechanism, and an image recognition mechanism mounted on the housing mechanism. The support mechanism includes a weight-measuring module mounted on the housing mechanism, and a support module mounted on the weight-measuring module and capable of supporting the solar cell module placed within the housing mechanism. The weight-measuring module can measure the weight of the solar cell module supported by the support module to obtain weight data.

[0007] The image recognition mechanism includes a first adjustment module installed on the housing mechanism, an image capture device installed on the first adjustment module, and an image analysis module signal-connected to the image capture device. The first adjustment module can drive the image capture device to move relative to the solar cell module carried by the carrier module. During the displacement, the image capture device can capture images of the solar cell module, and the image analysis module can analyze the images captured by the image capture device to obtain module size data corresponding to the solar cell body and product specification data corresponding to the product label.

[0008] The identification and measurement system for a solar cell module according to the present invention includes a solar cell body comprising a photovoltaic panel unit. Each photovoltaic panel unit has a backplate and a cover plate spaced vertically apart, and multiple photovoltaic panels arranged in a matrix and fixed between the cover plate and the backplate by an adhesive layer. The identification and measurement system further includes a measurement mechanism, comprising a second adjustment module installed in the housing mechanism, and a measurement module installed in the second adjustment module. The second adjustment module can drive the measurement module to move relative to the photovoltaic panels. The measurement module can measure the thickness of the cover plate, the height of the bottom surface of each photovoltaic panel relative to the bottom surface of the cover plate, and the height of the bottom surface of the backplate relative to the bottom surface of the cover plate, thereby obtaining data on the layered structure of the photovoltaic panels.

[0009] The identification and measurement system for solar cell modules of the present invention includes a housing mechanism that defines a measurement space having a forward-facing entrance and a rearward-facing exit. The carrying module includes a support body mounted on the weighing module and a conveying unit mounted on the support body and capable of carrying the solar cell module placed into the measurement space from the entrance. The conveying unit is capable of conveying the solar cell module towards the exit. The carrying mechanism also includes a rear stop positioning module disposed on the support body and between the rear end of the conveying unit and the exit. The rear stop positioning module can be controlled to change between a release position that does not obstruct the rearward conveying of the solar cell module by the conveying unit and a blocking position that allows the rearward conveying of the solar cell module to be positioned against the rear.

[0010] The identification and measurement system for solar cell modules of the present invention further includes a lateral positioning module installed on the housing mechanism. The lateral positioning module includes a guide unit extending left and right on the housing mechanism, two side pushers that are laterally displaceable on the guide unit, a transmission unit connected between the side pushers, and a driver installed on the housing mechanism and connected to the transmission unit. The driver can drive the transmission unit to synchronously drive the side pushers, causing the side pushers to move left and right in opposite directions along the guide unit, thereby causing the side pushers to cooperate in driving the solar cell module on the conveying unit to be positioned left and right.

[0011] The identification and measurement system for solar cell modules of the present invention includes a transmission unit comprising a rotating seat rotatably mounted on the housing mechanism and connected to the driver, and two transmission rods radially symmetrically and eccentrically pivoted on the rotating seat and respectively pivotally connected to the side pusher. The rotating seat can be driven by the driver to drive the transmission rods to rotate left and right relative to each other, thereby driving the side pusher to move left and right in opposite directions and left and right in opposite directions along the guide unit.

[0012] The identification and measurement system for solar cell modules of the present invention uses an optical measurement module to measure the photovoltaic panel unit to obtain the layered structure data of the photovoltaic panel.

[0013] The present invention discloses an identification and measurement system for a solar cell module. The solar cell body is positioned with the backplate facing upwards. The measurement mechanism is located below the supporting module. The measurement module includes a first measuring device, a second measuring device, and a third measuring device. The first measuring device scans the cover plate upwards with a confocal laser to measure the thickness of the cover plate. The third measuring device scans upwards with a color confocal laser to measure the distance D0 between itself and the bottom surface of the cover plate. The second measuring device scans upwards with a first infrared light of a first power, displacing it through at least two photoelectric plates, to measure the distance D3' between itself and the bottom surface of the backplate. It also scans upwards with a second infrared light of a second power, displacing it through at least two photoelectric plates, to measure the distance D2' between itself and the bottom surface of the corresponding photoelectric plate. The second measuring device analyzes D0, D2', and D3' to obtain the height of the bottom surface of the backplate relative to the bottom surface of the cover plate, and the height of the bottom surface of the photoelectric plate relative to the bottom surface of the cover plate. The second power is greater than the first power.

[0014] The identification and measurement system for a solar cell module according to the present invention includes a solar cell body comprising a photovoltaic panel unit, the photovoltaic panel unit having a back plate and a cover plate spaced vertically apart. The identification and measurement system further includes a measurement mechanism installed on the housing mechanism. The measurement mechanism includes a measurement module, the measurement module including a first measuring instrument and a second measuring instrument. The first measuring instrument has a first ultrasonic probe and can be driven to press against the side of the cover plate opposite to the back plate, and measures the thickness of the cover plate using ultrasonic measurement technology. The second measuring instrument has a second ultrasonic probe and can be driven to press against the side of the back plate opposite to the cover plate, and measures the thickness of the back plate using ultrasonic measurement technology.

[0015] The identification and measurement system for solar cell modules of the present invention includes a housing mechanism comprising a housing body defining the measurement space, a front door module installed at the front end of the housing body and capable of being opened and closed to seal the entrance, and a rear door module installed at the rear end of the housing body and capable of being opened and closed to seal the exit.

[0016] The identification and measurement system for solar cell modules of the present invention includes a weighing module comprising four load cells symmetrically arranged on the housing mechanism, and a support body mounted on the load cells.

[0017] The beneficial effects of this invention are as follows: through the structural design of the supporting mechanism and the image recognition mechanism, it can be used to automatically obtain the module size data and product specification data of the solar cell module to be recycled, which is quite convenient and practical.

[0032] Before the invention is described in detail, it should be noted that in the following description, the same components are represented by the same numbers.

[0033] See Figure 1 , 23. A first embodiment of the identification and measurement system 200 for a solar cell module 9 of the present invention is applicable to the specification identification and size measurement of a solar cell module 9 to be recycled. The solar cell module 9 includes a solar cell body 91, a junction box 92 disposed on the solar cell body 91, and a product label 93 affixed to the solar cell body 91. The solar cell body 91 has a photovoltaic panel unit 911 and a frame 916 surrounding the photovoltaic panel unit 911. The photovoltaic panel unit 911 includes a back plate 913 and a cover plate 914 spaced parallel to each other vertically, and a plurality of photovoltaic panels 912 arranged in a matrix and fixed between the opposing sides of the back plate 913 and the cover plate 914 via an adhesive layer 915. The junction box 92 and the product label 93 are both disposed on the side of the back plate 913 facing away from the cover plate 914. In this first embodiment, the solar cell module 9 is delivered into the identification and measurement system 200 with the backplate 913 facing upwards, so the junction box 92 and the product label 93 are exposed facing upwards.

[0034] See Figure 3 , 4 5. The identification and measurement system 200 includes a housing mechanism 3, a support mechanism 4 mounted on the housing mechanism 3, an image recognition mechanism 5 and a measurement mechanism 6, and a control device 7 that signals the housing mechanism 3, the support mechanism 4, the image recognition mechanism 5 and the measurement mechanism 6.

[0035] The housing mechanism 3 includes a housing body 31 that defines a closed measurement space 310, and a front door module 32 and a rear door module 33 respectively installed at the front and rear ends of the housing body 31. The housing body 31 is composed of a combination of rods and wall panels that define the measurement space 310. Since there are many structural types of the housing body 31, and it is not the focus of this invention, it will not be described in detail. To facilitate the explanation of the other structural components installed in the housing body 31, the following will be described... Figure 3 Some of the rods and wall panels are omitted so that the measurement space 310 is exposed. Therefore, in practice, the shell body 31 is not limited to the form shown in the attached drawings.

[0036] The measurement space 310 has a rearward exit 311 and a forward entrance 312. The front door module 32 includes a front door panel 321 mounted in the front end of the housing body 31 and closing the entrance 312, and a front door actuator 322 mounted in the housing body 31 and connected to the front door panel 321. The front door actuator 322 can be controlled by the control device 7 to open the front door panel 321, exposing the entrance 312. The rear door module 33 includes a rear door panel 331 mounted in the rear end of the housing body 31 and closing the exit 311, and a rear door actuator 332 mounted in the housing body 31 and connected to the rear door panel 331. The rear door actuator 332 can be controlled by the control device 7 to open the rear door panel 331, exposing the exit 311.

[0037] See Figure 3 , 6 7, 8. The bearing mechanism 4 is located within the measurement space 310 and includes a weighing module 41 installed on the shell body 31, a bearing module 42 disposed on the weighing module 41, two rear stop positioning modules 43 spaced apart on the left and right sides of the bearing module 42, and two lateral positioning modules 44 spaced apart on the front and rear sides of the bearing module 42. The weighing module 41 includes four load cells 411 symmetrically arranged on the shell body 31.

[0038] The support module 42 includes a support base 421 spanning the load cell 411, and a conveying unit 422 mounted on the support base 421 and located between the inlet 312 and the outlet 311. The conveying unit 422 can be used to receive the solar cell module 9 placed into the measurement space 310 from the inlet 312 and convey the solar cell module 9 towards the outlet 311. The weighing module 41 can measure the weight of the solar cell module 9 carried by the support module 42 in cooperation with the load cell 411 to obtain a weight data.

[0039] In this first embodiment, the conveying unit 422 has two annular conveyor belts 423 spaced horizontally and extending forward and backward, multiple support seats 424 spaced horizontally and arranged forward and backward on the carrier body 421, and a conveying driver 425 for driving the conveyor belts 423. The support seats 424 abut against the lower half of the upper section of the conveyor belts 423, so that the upper half of the conveyor belts 423 can be maintained at a predetermined height when carrying and conveying the solar cell module 9. However, in another embodiment of the present invention, the conveying unit 422 may also adopt a roller conveying structure design with multiple rollers extending horizontally and arranged forward and backward. Since the above two types of conveying units 422 are both prior art and numerous, they will not be described in detail, and the implementation is not limited to the above embodiments.

[0040] See Figure 3 , 6 9. The rear stop positioning module 43 is installed at the rear end of the support body 421, located inside the outlet 311. Each rear stop positioning module 43 can be driven to move vertically relative to the support body 421, thereby varying between a blocking position protruding above the top surface of the conveying unit 422 and a release position below the top surface of the conveying unit 422. When the rear stop positioning module 43 is in the blocking position, it will block the conveying unit 422 and the outlet 311, allowing the solar cell module 9, which is being conveyed by the conveying unit 422 towards the outlet 311, to be positioned backward. When the rear stop positioning module 43 is in the release position, it will not block the solar cell module 9 being conveyed backward by the conveying unit 422, allowing the solar cell module 9 to be conveyed through the outlet 311.

[0041] In this first embodiment, each rear gear positioning module 43 is a telescopic cylinder that can extend and retract vertically. However, since there are many structural types of the rear gear positioning module 43 that can be used to change between the release position and the blocking position, for example, the rear gear positioning module 43 can be designed to swing up and down between the release position and the blocking position. Therefore, in practice, the rear gear positioning module 43 is not limited to the above-described embodiments.

[0042] See Figure 3 , 8 9. Each of the lateral positioning modules 44 includes a guide unit 441 extending laterally and mounted on the support body 421, two side pushers 442 slidably mounted on the guide unit 441, a driver 443 mounted on the support body 421, and a transmission unit 444 connecting the side pushers 442 and the driver 443. The transmission unit 444 includes a rotating seat 445 mounted on the support body 421 and rotatable by the driver 443, and two radially symmetrically eccentrically pivoted to the rotating seat 445 and respectively pivotally connected to the side pushers 442.

[0043] The driver 443 of each of the lateral positioning modules 44 can be controlled to drive the rotating seat 445, so that the rotating seat 445 drives the transmission rod 446 to swing left and right relative to each other, thereby driving the side pusher 442 to move left and right towards each other or left and right away from each other along the guide unit 441.

[0044] When the side pusher 442 of the lateral positioning module 44 is driven to move left and right in opposite directions, it can be used to push the two sides of the solar cell module 9 carried by the conveying unit 422 in opposite directions, thereby driving the solar cell module 9, which has left and right tilting, to be straightened and positioned on the conveying unit 422.

[0045] See Figure 3 , 6 10. The image recognition mechanism 5 includes a first adjustment module 51 that extends forward and backward and is installed on the housing body 31 and is spaced above the transport unit 422, an image capture device 52 installed on the first adjustment module 51, and an image analysis module 53 that is signal-connected to the image capture device 52.

[0046] The first adjustment module 51 includes a first slide rail 511 extending forward and backward on the housing body 31, a first movable base 512 mounted on the first slide rail 511 and for mounting the image capture device 52, and a first drive unit 513 mounted on the first slide rail 511 and connected to the first movable base 512. The first drive unit 513 can drive the first movable base 512 to move forward and backward along the first slide rail 511, thereby driving the image capture device 52 to move forward and backward relative to the solar cell module 9 carried by the transport unit 422.

[0047] The image capture device 52 can be controlled to capture images downwards along a local length segment of the solar cell module 9, thereby capturing multiple overlapping segment images during the forward and backward displacement process.

[0048] The image analysis module 53 is integrated with the control device 7. It can aggregate the segmented images to construct a top-side appearance image of the solar cell module 9, and obtain an image of the product label 93. It further analyzes the top-side appearance image to obtain the length and width dimensions of the solar cell body 91, the dimensions of the junction box 92, and the relative positions of the solar cell body 91 and the junction box 92, thus obtaining module size data. It can also analyze and identify the text data in the product label 93 image to obtain product specification data for the solar cell module 9. The product specification data includes, but is not limited to, brand, model, place of origin, and power.

[0049] See Figure 3 , 911. The measuring mechanism 6 includes a second adjustment module 61 mounted on the housing body 31 and located below the supporting mechanism 4, and a measuring module 62 mounted on the second adjustment module 61. The second adjustment module 61 includes a second slide rail 611 extending horizontally from front to back and obliquely to the left and right, a second movable seat 612 mounted obliquely on the second slide rail 611, and a second drive unit 613 mounted on the housing body 31 and connected to the second movable seat 612. The measuring module 62 is mounted on the second movable seat 612.

[0050] In this first embodiment, the extension direction of the second slide rail 611 corresponds to the extension lines of two opposite corners of one of the photoelectric plates 912 of the upper photoelectric plate unit 911. The second drive unit 613 can drive the second moving seat 612 to move along the second slide rail 611, thereby causing the measurement module 62 to move relative to the photoelectric plate unit 911 across multiple diagonally adjacent photoelectric plates 912. In this first embodiment, it crosses at least two diagonally adjacent photoelectric plates 912.

[0051] See Figure 2 , 9 10. The measurement module 62 can measure the thickness D1 of the cover plate 914, the height D2 of the bottom surface of each photoelectric plate 912 relative to the bottom surface of the cover plate 914, and the height D3 of the bottom surface of the back plate 913 relative to the bottom surface of the cover plate 914, thereby obtaining photoelectric plate layer structure data. The measurement module 62 includes a first measuring instrument 621, a second measuring instrument 622, and a third measuring instrument 623 located at the same reference height.

[0052] The first measuring device 621 can be used to measure the thickness D1 of the cover plate 914. In this first embodiment, the first measuring device 621 uses an optical measurement method to emit a confocal laser of predetermined power, such as, but not limited to, ultraviolet laser, upward toward the photoelectric plate unit 911. When the confocal laser shines upward onto the cover plate 914, part of the confocal laser is absorbed by the adhesive layer 915, and part of the confocal laser is reflected at the interface between the cover plate 914 and the adhesive layer 915. The first measuring device 621 measures the time difference between the confocal laser reflected from the bottom surface of the cover plate 914 and the confocal laser reflected from the interface between the cover plate 914 and the adhesive layer 915, and statistically analyzes the time difference measured at each measurement point during its displacement process to obtain the thickness D1 of the cover plate 914.

[0053] The third measuring device 623 can optically measure the distance D0 between itself and the bottom surface of the cover plate 914. In this first embodiment, the third measuring device 623 scans and measures the bottom surface of the cover plate 914 using color confocal laser displacement measurement technology to obtain the distance D0 between itself and the bottom surface of the cover plate 914. However, in practice, the method by which the third measuring device 623 measures the distance D0 is not limited to this.

[0054] The second measuring device 622 can optically measure its distance D3' from the bottom surface of the back plate 913 and its distance D2' from the bottom surface of each of the photoelectric plates 912 being measured. Based on the D0 measured by the third measuring device 623, it analyzes and obtains the height D3 of the bottom surface of the back plate 913 relative to the bottom surface of the cover plate 914, and the height D2 of the bottom surface of each of the aforementioned photoelectric plates 912 relative to the bottom surface of the cover plate 914. In this first embodiment, the second measuring device 622 can emit a first infrared light of a first power and a second infrared light of a second power upwards toward the photoelectric plate unit 911, where the first power is less than the second power.

[0055] When the second measuring device 622 scans upwards through at least two of the photoelectric plates 912 with a first infrared light of a first power, the power of the first infrared light is designed to be completely absorbed by the photoelectric plates 912 without being reflected by them, but it will penetrate upwards through the adhesive layer 915 located between the two photoelectric plates 912 and be directed towards the back plate 913. When the second infrared light scans upwards through at least two of the photoelectric plates 912, the power of the second infrared light is designed not to be completely absorbed by the photoelectric plates 912, that is, the second infrared light will be partially absorbed and partially reflected by the photoelectric plates 912, and the second infrared light will also penetrate upwards through the adhesive layer 915 located between the two photoelectric plates 912 and be directed towards the back plate 913.

[0056] When the second measuring device 622 emits the first infrared light, the first infrared light penetrates upward through the cover plate 914 and strikes one of the photoelectric plates 912. It is completely absorbed by the photoelectric plate 912 without being reflected, and the second measuring device 622 will not detect the reflected first infrared light. When the first infrared light strikes upward onto the adhesive layer 915 between the two photoelectric plates 912, the first infrared light penetrates upward through the adhesive layer 915 and strikes the back plate 913, where it is reflected downward by the bottom surface of the back plate 913. The second measuring device 622 will then detect the reflected first infrared light.

[0057] When the second measuring device 622 emits the second infrared light, the second infrared light also penetrates the cover plate 914 upwards and is directed towards one of the photoelectric plates 912. Because the power of the second infrared light is greater than that of the first infrared light, and it cannot be completely absorbed by either photoelectric plate 912, when the second infrared light shines on one of the photoelectric plates 912, it is partially absorbed and partially reflected. Therefore, the second measuring device 622 will measure the second infrared light reflected from the bottom surface of the photoelectric plate 912. When the second infrared light shines on the adhesive layer 915 located between the two photoelectric plates 912, it penetrates the adhesive layer 915 upwards and is directed towards the back plate 913, where it is reflected by the bottom surface of the back plate 913. The second measuring device 622 will then measure a large amount of the second infrared light. In this first embodiment, since the signal generated by sensing the second infrared light reflected by the back plate 913 is too large, the second measuring instrument 622 will treat the sensing result of the second infrared light reflected by the back plate 913 as noise and filter it out, and will only retain the sensing result of the second infrared light reflected by the photoelectric plate 912.

[0058] The second measuring device 622 statistically analyzes the reflection time data of the first infrared light measured during its displacement to obtain the distance D3' between it and the bottom surface of the back plate 913. It then subtracts D0 from D3' to obtain the height D3 of the bottom surface of the back plate 913 relative to the bottom surface of the cover plate 914. The second measuring device 622 also statistically analyzes the reflection time data of the second infrared light measured during its displacement to obtain the distance D2' between it and the bottom surface of each measured photoelectric plate 912. It then subtracts D0 from D2' to obtain the height D2 of the bottom surface of each measured photoelectric plate 912 relative to the bottom surface of the cover plate 914.

[0059] The control device 7 is signal-connected to the front door module 32, the rear door module 33, the weighing module 41, the load-bearing module 42, the rear window positioning module 43, the lateral positioning module 44, the image recognition mechanism 5, and the measuring mechanism 6, and can be used to control the operation of the modules and mechanisms. Furthermore, the control device 7 integrates the weight data from the weighing module 41, the module size data and product specification data from the image analysis module 53, and the thickness D1, height D3, and height D2 data measured by the measuring module 62, to establish identification and measurement data corresponding to the solar cell module 9.

[0060] In this first embodiment, multiple lateral positioning modules 44 spaced apart are provided. However, in other embodiments of the present invention, only one lateral positioning module 44 may be provided. By extending and expanding the front-to-back length of the side pusher 442, a single lateral positioning module 44 can be used to push and straighten the solar cell module 9 laterally. Similarly, in another embodiment of the present invention, only one rear-block positioning module 43 can be used to position the solar cell module 9 backward. However, in practice, in other embodiments of the present invention, it is not necessary to provide the rear-block positioning module 43 and the lateral positioning module 44. The supporting module 42 can directly support and position the solar cell module 9 placed in the measurement space 310.

[0061] In this first embodiment, the image recognition mechanism 5 and the measurement mechanism 6 are respectively disposed above and below the carrier module 42. However, in another embodiment of the present invention, the solar cell module 9 that is transported into the measurement space 310 can be reversed vertically, and the positions of the image recognition mechanism 5 and the measurement mechanism 6 can be interchanged vertically.

[0062] See Figure 12 , 13 The difference between a second embodiment of the solar cell module identification and measurement system 200 of the present invention and the first embodiment lies in the structural design of the measurement mechanism 6. For ease of explanation, the following description will only focus on the differences between the embodiments.

[0063] In this second embodiment, the measuring mechanism 6 includes a measuring module 62 mounted on the housing body 31. The measuring module 62 includes a first measuring instrument 621 disposed below the conveying unit 422 and a second measuring instrument 622 disposed above the conveying unit 422.

[0064] The first measuring device 621 has an upward-facing first ultrasonic probe 624 that can be controlled to protrude upwards. The first ultrasonic probe 624 is pressed against the bottom surface of the cover plate 914 of the photoelectric plate unit 911 and sends ultrasonic waves of a specific power toward the photoelectric plate unit 911. The ultrasonic signals reflected by the interfaces of each layer structure are measured and analyzed by ultrasonic measurement technology to obtain the thickness D1 of the cover plate 914 and the thickness D4 of the adhesive layer 915 between the cover plate 914 and the photoelectric plate 912 above it.

[0065] The second measuring device 622 has a downward-facing second ultrasonic probe 625 that can be controlled to extend downwards. The second ultrasonic probe 625 is pressed against the top surface of the back plate 913 of the photoelectric plate unit 911 and sends ultrasonic waves of a specific power toward the photoelectric plate unit 911. By measuring and analyzing the ultrasonic signals reflected at the interfaces of each layer structure through ultrasonic measurement technology, the thickness D5 of the back plate 913 is obtained, and the thickness D6 of the adhesive layer 915 between the back plate 913 and the photoelectric plate 912 below it is also measured.

[0066] The first measuring instrument 621 and the second measuring instrument 622 can be used to design the thickness measurement of the layered structure of the photoelectric plate unit 911 through ultrasonic measurement technology. This can be used to accurately measure the thickness D1 of the cover plate 914, the thickness D5 of the back plate 913, and the thicknesses D4 and D6 of the adhesive layer 915 between the cover plate 914, the back plate 913 and the photoelectric plate 912.

[0067] However, in other embodiments of the present invention, the first measuring device 621 may also measure the thickness D1 of the cover plate 914 by means of eddy current or other methods. Since there are many ways for the first measuring device 621 to measure the thickness D1 of the cover plate 914, the implementation is not limited to the above embodiments.

[0068] In summary, the structural design of the supporting mechanism 4 and the image recognition mechanism 5 can be used to automatically obtain the module size data and product specification data of the solar cell module 9 to be recycled. This allows the recycling system, which will subsequently recycle the module by physical means, to dismantle and recycle the frame 916 and the junction box 92 based on the module size data and the product specification data, which is quite convenient and practical.

[0069] Furthermore, the design allows for the measurement of data such as D1 to D6 of the photoelectric panel unit 911 through the measuring mechanism 6, enabling the subsequent recycling system to physically recycle each layer of the photoelectric panel unit 911.

[0070] In addition, the structural design of the rear positioning module 43 and the lateral positioning module 44 of the bearing mechanism 4 can be used to guide and position the solar cell module 9 that is sent into the measurement space 310 of the housing mechanism 3, which helps to improve the accuracy of identification and measurement.

[0071] Therefore, the identification and measurement system 200 for solar cell module 9 of the present invention is indeed a highly innovative and practical creation, and thus can indeed achieve the purpose of the present invention.

[0072] The above description is merely an embodiment of the present invention and should not be construed as limiting the scope of the present invention. Any simple equivalent changes and modifications made in accordance with the claims and description of the present invention shall still fall within the scope of the present invention.
