Therefore, it is necessary to test the incoming silicon wafers. The main testing directions include silicon wafer surface unevenness, minority carrier lifetime, resistivity, P / N type and microcracks.

[0003] The existing Chinese patent application with publication number CN115846223A discloses a photovoltaic cell sorting device, including a sorting operation table.

[0005] 1. As the core component of photovoltaic modules, the quality of existing photovoltaic cells directly affects the power generation efficiency and safety of the modules. However, the production of cells is susceptible to many defects due to factors such as processing technology and materials. Therefore, the research on intelligent defect detection of photovoltaic cells has important engineering value and significance. In the existing technology, although machine vision algorithms have been applied to the field of photovoltaic cell defect detection, due to the difficulties such as the wide variety of defects and high position uncertainty, its detection efficiency is low and it is difficult to meet the requirements of more efficient detection and sorting.

[0006] 2. When the existing photovoltaic cell sorting equipment is testing photovoltaic cells, it is difficult to realize the flipping test of the upper and lower surfaces in the same testing process. During the specific test, all photovoltaic cells need to be tested on a single surface first, and then uniformly allocated by the subsequent distribution system, and then the other surface is tested. The whole testing process is time-consuming and laborious, which is not conducive to the long-term and efficient development of the entire sorting line. Summary of the invention

[0048] Compared with the prior art, one or more of the above technical solutions have the following beneficial effects:

[0049] 1. In the automatic sorting equipment for photovoltaic cells, the high-precision weighing instrument can measure the weight of the entire structure on the first connecting frame with high precision. Since the weights of the structures such as the first connecting frame, the second connecting frame, the connecting frame, and the clamping and supporting components are all constant, the weight of the photovoltaic cell can be obtained after the photovoltaic cell is clamped by the clamping and supporting components, and then the weight is measured by the high-precision weighing instrument and then the constant weight is subtracted. Since photovoltaic cells are susceptible to many defects due to factors such as processing technology and materials during production, the weight of defective photovoltaic cells is mostly inconsistent with the weight of qualified photovoltaic cells. Therefore, after the photovoltaic cells are weighed by the high-precision weighing instrument, the defective photovoltaic cells can be quickly determined, and then the machine vision algorithm is used to further detect the photovoltaic cells that are weighed without defects. The combination of the two not only reduces the workload of the machine vision algorithm, but also improves the detection effect, and can meet more efficient detection and sorting;

[0050] 2. In the automatic photovoltaic sheet sorting equipment, the supporting plate can be made vertical or horizontal by the driving member. When the supporting plate in the lower supporting member is driven to be horizontal and the supporting plate in the upper supporting member is driven to be vertical, combined with the lateral clamping of the clamping airbag, the photovoltaic sheet to be inspected can be supported and clamped, so that the upper surface of the photovoltaic sheet can be inspected by the inspection component. When the inspected photovoltaic sheet needs to be delivered to the collection component, the supporting plate in the lower supporting member is driven to be vertical, and the clamping airbag cancels the clamping force to realize the vertical drop of the photovoltaic sheet, thereby completing the unloading. The whole process is quick to operate and does not require manual operation. The process saves time and effort, and is more conducive to the rapid and efficient inspection and sorting of photovoltaic sheets.

[0051] 3. In the photovoltaic cell automatic sorting equipment, after the first motor is started by the external controller, the first motor will drive the first rotating shaft to rotate, and then the entire connecting frame can be turned 180 degrees. In the initial state, the supporting plate in the lower supporting member is supported horizontally, and the supporting plate in the upper supporting member is vertically moved to make way, so as to facilitate the detection of the upper surface of the photovoltaic cell by the detection component. When the lower surface of the photovoltaic cell needs to be detected, the supporting plates in the upper and lower supporting members clamp the photovoltaic cell, and then the connecting frame is turned over, and the supporting plate in the upper supporting member after the flip is turned vertically to realize the detection of the original lower surface of the photovoltaic cell, so as to facilitate the rapid flipping detection of the upper and lower surfaces in the same detection process, improve the detection efficiency of the overall process, and be more conducive to the long-term and efficient development of the entire sorting assembly line;

[0052] 4. In the automatic photovoltaic cell sorting equipment, a collecting component is provided to collect discarded photovoltaic cells. When the detection component or the high-precision weighing instrument detects inferior photovoltaic cells, the driving component is started to make the photovoltaic cell correspond to the top of the collecting component, and then the clamping effect of the clamping support component is cancelled, so that the inferior photovoltaic cell falls into the collecting component, thereby completing the collection of inferior photovoltaic cells. The whole sorting process is fast and efficient, convenient for accurate classification, and has better use effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0073] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0074] See also Figure 1-Figure 10 , a photovoltaic sheet automatic sorting device, including a device box 1, and a device platform 2 is arranged on the top of the device box 1, and also includes a detection component 3, a bearing component 4, a connection frame 5, a clamping and supporting component 6, a collection component 7 and a driving component 8. Among them:

[0075] At least three detection components 3 are provided, and the three detection components 3 are arranged in a circular array on the top of the equipment platform 2. In this embodiment, the detection component 3 includes a photovoltaic silicon wafer detector, a microcrack detection module and two detection modules. Among them, the photovoltaic silicon wafer detector is used to detect the surface unevenness of the photovoltaic silicon wafer, and at the same time detect the appearance parameters such as the size and diagonal of the photovoltaic silicon wafer. The microcrack detection module is used to detect the internal microcracks of the photovoltaic silicon wafer. One of the online test modules mainly tests the body resistivity and type of silicon wafer, and the other module is used to detect the electronic life of the silicon wafer. Before performing the electronic life and resistivity tests, it is necessary to first detect the diagonal and microcracks of the silicon wafer, and automatically remove the damaged silicon wafer. The silicon wafer detection equipment can automatically load and unload the wafer, and can put the unqualified products in a fixed position, thereby improving the detection accuracy and efficiency.

[0076] The number of the carrying components 4 is the same as the number of the detecting components 3 , and the carrying components 4 and the detecting components 3 correspond to each other one by one and are aligned.

[0077] The number of the connection frames 5 is the same as the number of the supporting components 4 , and the multiple connection frames 5 are respectively disposed on the top of the multiple supporting components 4 .

[0078] The number of the clamping and supporting components 6 is the same as the number of the connecting frames 5 , and the plurality of clamping and supporting components 6 are respectively disposed on the plurality of connecting frames 5 .

[0079] The number of the collecting components 7 is the same as the number of the detecting components 3 , and the three collecting components 7 are arranged in a circular array on the side of the equipment box 1 , and the three collecting components 7 and the three detecting components 3 have non-overlapping projections on the same horizontal plane.

[0080] The driving assembly 8 is disposed on the top of the equipment platform 2 , and the driving assembly 8 is used to drive the bearing assembly 4 to rotate.

[0081] Further, in this embodiment, the bearing assembly 4 includes a sliding block 41, a high-precision weighing instrument 42, a first connecting frame 43 and a second connecting frame 44, wherein the high-precision weighing instrument 42 is arranged at the top of the sliding block 41, the first connecting frame 43 is arranged at the weighing end of the top of the high-precision weighing instrument 42, the number of the second connecting frames 44 is two, the two second connecting frames 44 are respectively arranged at the two ends of the first connecting frame 43, and the connecting frame 5 is arranged between the two second connecting frames 44. That is, according to the above structure, combined with Figure 1 and Figure 2 It can be seen that the high-precision weighing instrument 42 set up can perform high-precision weighing of the entire structure on the first connecting frame 43. Since the weights of the structures such as the first connecting frame 43, the second connecting frame 44, the connecting frame 5, and the clamping and supporting assembly 6 are all constant, after the photovoltaic sheet is clamped by the clamping and supporting assembly 6, the weight is measured by the high-precision weighing instrument 42 and then the constant weight is subtracted to obtain the weight of the photovoltaic sheet. Since photovoltaic sheets are easily affected by processing technology, materials and other factors during production and produce many defects, the weight of defective photovoltaic sheets is mostly inconsistent with the weight of qualified photovoltaic sheets. Therefore, after the photovoltaic sheets are weighed by the high-precision weighing instrument 42, the defective photovoltaic sheets can be quickly determined, and then the machine vision algorithm can be used to further detect the photovoltaic sheets that are weighed without defects. The combination of the two not only reduces the workload of the machine vision algorithm, but also improves the detection effect, and can meet more efficient detection and sorting.

[0082] Furthermore, the driving assembly 8 includes a second mounting frame 81, a second rotating shaft 82, a second gear 83, a second motor 84, a connecting block 85, an annular rack 86 and an annular guide rod 87, wherein the second mounting frame 81 is fixed to the top of the equipment platform 2, the bottom of the second rotating shaft 82 is rotatably connected to the top of the equipment platform 2, and the top of the second rotating shaft 82 passes through the top of the second mounting frame 81, the second motor 84 is installed on the top of the second mounting frame 81 and is connected to the top of the second rotating shaft 82, the second gear 83 is sleeved on the outside of the second rotating shaft 82, and the connecting block 85 is fixed to the fixed end of the high-precision weighing instrument 42, the annular rack 86 is fixed to the end of the connecting block 85, and the annular rack 86 is meshed with the second gear 83, the annular guide rod 87 is fixed to the top of the equipment platform 2, and the bottom of the sliding block 41 is slidably connected to the outside of the annular guide rod 87.

[0083] Therefore, when the driving assembly 8 is in use, when the second motor 84 is started by the external controller, the second motor 84 drives the second rotating shaft 82 and the second gear 83 to rotate. Since the second gear 83 is meshed with the annular rack 86, and the annular rack 86 is fixed to the connecting block 85, when the annular rack 86 rotates, the connecting block 85 drives the entire bearing assembly 4, the connecting frame 5 and the clamping support assembly 6 to rotate. Figure 1 It can be seen that since the number of the supporting components 4, the detection components 3 and the collecting components 7 are the same, and the collecting components 7 and the driving components 8 are interlaced with each other, the setting of the driving component 8 can make the supporting component 4 correspond to the collecting component 7 or the detection component 3, thereby facilitating the unloading or detection of the photovoltaic cells on the clamping support component 6.

[0084] In addition, in this embodiment, the collection component 7 includes a fixed frame 71, a collection box 72 and a limit block 73, wherein the fixed frame 71 is fixed to the bottom of the equipment platform 2, the collection box 72 is arranged inside the fixed frame 71, and the limit block 73 is fixed to the side of the collection box 72 and cooperates with the fixed frame 71, so that the collection box 72 can be taken out of the fixed frame 71 from bottom to top.

[0085] The collection component 7 is used to collect discarded photovoltaic sheets. When the detection component 3 or the high-precision weighing instrument 42 detects a low-quality photovoltaic sheet, the driving component 8 can be started to make the photovoltaic sheet correspond to the top of the collection component 7, and then the clamping effect of the clamping support component 6 is cancelled, so that the low-quality photovoltaic sheet falls into the collection component 7, thereby completing the collection of low-quality photovoltaic sheets. The entire sorting process is fast and efficient, convenient for accurate classification, and has a better use effect. When the photovoltaic sheet is detected as qualified, it can be transported and collected by the handling robot on the existing production line. Of course, a corresponding collection component 7 for storing qualified photovoltaic sheets can also be set under the bearing component 4. The specific method to be used depends on the manufacturer.

[0086] At the same time, in order to achieve high-precision docking between the supporting component 4 and the collecting component 7 or the detecting component 3, a connecting plate 9 is further provided at the bottom of the connecting block 85, and a light generator 10 is provided at the bottom of the connecting plate 9, and a light receiver 11 matched with the light generator 10 is provided at the top of the equipment platform 2. The number of light generators 10 is the same as the number of supporting components 4, and the number of light receivers 11 is twice the number of light generators 10. Therefore, through the cooperation between the light receivers 11 and the light generators 10, high-precision docking can be achieved between the supporting component 4 and the collecting component 7 or the detecting component 3.

[0087] Furthermore, in the present embodiment, the clamping supporting assembly 6 includes a supporting member 61, a clamping airbag 62 and a flipping member 63, wherein there are two supporting members 61, and the two supporting members 61 are symmetrically arranged inside the connecting frame 5, at least four clamping airbags 62 are arranged, and the four clamping airbags 62 are respectively arranged on the four side walls inside the connecting frame 5, the flipping member 63 is arranged on the side of the second connecting frame 44, and the flipping member 63 is used to drive the connecting frame to flip. Each supporting member 61 includes a rotating rod 611, a supporting plate 612, a magnet 613 and a driving member 614, wherein each supporting member 61 has two rotating rods 611, and the two rotating rods 611 are rotatably connected to the left and right sides of the connecting frame 5 respectively, the number of the supporting plates 612 is the same as the number of the rotating rods 611, and the supporting plates 612 are connected to the outside of the rotating rods 611 one by one, the magnet 613 is fixed on the inner wall of the connecting frame 5, the supporting plate 612 is made of magnetic material, and the driving member 614 is used to drive the two rotating rods 611 to rotate.

[0088] That is, when in use, the driving member 614 can make the supporting plate 612 be in a vertical or horizontal shape. When the supporting plate 612 in the lower supporting member 61 is driven to be in a horizontal shape and the supporting plate 612 in the upper supporting member 61 is driven to be in a vertical shape, combined with the lateral clamping of the clamping airbag 62, the photovoltaic sheet to be inspected can be supported and clamped, so that the upper surface of the photovoltaic sheet can be inspected by the detection component 3. When the inspected photovoltaic sheet needs to be delivered to the collection component 7, the supporting plate 612 in the lower supporting member 61 is driven to be in a vertical shape, and the clamping airbag 62 cancels the clamping force to achieve the vertical falling of the photovoltaic sheet, thereby completing the unloading. The whole process is quick to operate and does not require manual operation. The process saves time and effort, and is more conducive to the rapid and efficient detection and sorting of photovoltaic sheets.

[0089] Specifically, in this embodiment, the driving member 614 includes a first gear 6141, a straight rack 6142, a fixed block 6143, a sliding rod 6144 and a bidirectional electric push rod 6145. The number of the first gear 6141 is the same as the number of the rotating rod 611 and is sleeved on the outside of the rotating rod 611 one by one. The bidirectional electric push rod 6145 is fixed to the outer side of the connecting frame 5, and the two output ends of the bidirectional electric push rod 6145 are fixedly connected with the straight rack 6142, the straight rack 6142 and the first gear 6141 are meshed with each other, and the side of the straight rack 6142 is also fixed with a sliding rod 6144. The fixed block 6143 is fixed to the side of the connecting frame 5, and the sliding rod 6144 passes through the fixed block 6143 and slides with the fixed block 6143.

[0090] Therefore, when in use, after the dual-axis electric push rod is started through the external controller, the two-hand electric push rod can drive the straight rack 6142 to move, and at the same time the sliding rod 6144 slides on the fixed block 6143, providing a more stable sliding effect for the straight rack 6142. When the straight rack 6142 moves, the first gear 6141 will rotate, and then the rotating rod 611 will drive the supporting plate 612 to rotate, so as to adjust the vertical or horizontal state of the supporting plate 612.

[0091] In addition, in this embodiment, the flip member 63 includes a first rotating shaft 631, a first mounting frame 632 and a first motor 633, wherein the number of the first rotating shafts 631 is two and they are respectively fixed on both sides of the connecting frame 5, and the first rotating shaft 631 is rotatably connected to the second connecting frame 44, the first mounting frame 632 is installed on the side of the second connecting frame 44, the first motor 633 is installed on the first mounting frame 632, and the output end of the first motor 633 is connected to the end of one of the first rotating shafts 631.

[0092] That is, when in use, after the first motor 633 is started by the external controller, the first motor 633 will drive the first rotating shaft 631 to rotate, and then the entire connecting frame can be flipped 180 degrees. In the initial state, the supporting plate 612 in the lower supporting member 61 is supported horizontally, and the supporting plate 612 in the upper supporting member 61 makes way vertically, so as to facilitate the detection of the upper surface of the photovoltaic cell by using the detection component 3. When the lower surface of the photovoltaic cell needs to be detected, after the supporting plates 612 in the upper and lower supporting members 61 clamp the photovoltaic cell, the connecting frame 5 is flipped, and then the supporting plate 612 in the flipped upper supporting member 61 is turned vertically to realize the detection of the original lower surface of the photovoltaic cell, thereby facilitating the rapid flipping detection of the upper and lower surfaces in the same detection process, improving the detection efficiency of the overall process, and being more conducive to the long-term and efficient development of the entire sorting line.

[0093] In addition, in order to facilitate the high-precision flipping of the entire connection frame 5, the flipping member 63 also includes a disk 634, a scale line 635 and an indicator needle 636, wherein the disk 634 is fixed to the end of another first rotating shaft 631, the scale lines 635 are arranged at equal intervals on the outer end surface of the disk 634, and the indicator needle 636 is fixed to the side of the second connecting frame 44 and matches the scale line 635. When the connection frame 5 is flipped, the first rotating shaft 631 can also drive the disk 634 to rotate, so after the connection frame 5 and the disk 634 are rotated, through the corresponding changes between the scale line 635 on the disk 634 and the indicator needle 636, it can also be observed whether a large error occurs in the flipping angle at this time, which is convenient for subsequent timely maintenance and is conducive to improving the sorting effect of the entire sorting process.

[0094] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
