[0002] The solar cell sorting machine is a key equipment for screening and classifying solar cell pieces in the photovoltaic industry, which mainly functions to improve production efficiency, ensure product quality, and provide high-quality cell pieces for subsequent photovoltaic module production. The solar cells to be sorted are transported to the detection box by the conveying frame for detection, and different defective and qualified solar cells are unloaded into the corresponding sorting box by the unloading device according to the detection results. During sorting, the solar cells randomly fall into the sorting box through the chute. Since the solar cells are relatively fragile, if the falling distance is too high when falling into the sorting box, it is easy to cause mutual collision between the solar cells, thereby causing damage to the solar cells. If the falling distance is too short when falling into the sorting box, it will greatly reduce the collection amount of the solar cells.

DETAILED DESCRIPTION

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] like Figures 1-4 As shown, the present invention provides a solar cell sorting device, including a solar cell sorting component detection box 13 and a conveyor belt 17. The solar cell sorting component includes a conveyor frame 10 and a sorting box 11 arranged on its side. The inner side of the conveyor frame 10 is provided with an unloading component 50 for transferring the solar cells on it to the sorting box 11. The conveyor frame 10 and the unloading component 50 are connected by a slide 12. The sorting box 11 is equipped with a straightening assembly 20 for straightening and arranging the sorted solar cells. The straightening assembly 20 includes storage cavities 21 on both sides of the sorting box 11 for storing the straightening frame 22. The bottom of the storage cavity 21 is fixedly connected to a first spring 23 for pushing the straightening frame 22 upward. The inner walls on both sides of the sorting box 11 are provided with first sliding grooves 24 for pushing the straightening frame 22 out of the storage cavity 21. The inner walls on both sides of the sorting box 11 are also provided with second sliding grooves 25 for the straightening frame 22 to slide vertically. The straightening frame 22 is provided with an integrally formed sliding arm 221 and a limiting seat 222. The sorting box 11 is provided with supplementary units 29 on both sides. The straightening frame 22 and the slide 12 are in the same direction and angle. The rear part of the first slide 24 is provided with a limiting rod 28 that slides through to the outside of the sorting box 11, and one end of the limiting rod 28 is fixedly connected to a force-bearing seat 26 for bearing the impact of the straightening frame 22. The outside of the limiting rod 28 is fitted with a second spring 27 inside the first slide 24. The supplementary unit 29 includes a rack 291 integrally formed with one of the limiting rods 28. The rear end of the sorting box 11 is rotatably connected to a rotating shaft 293 via a connecting seat 292. One end of the rotating shaft 293 is fixedly connected to a first gear 294 that meshes with the rack 291, and the other end of the rotating shaft 293 is fixedly connected to a second gear 295. Both sides of the sorting box 11 are rotatably connected to lead screws 296, and one end of the lead screw 296 is fixedly connected to a third gear 297. The third gear 297 and the second gear 295 are meshed and connected by a toothed chain 298. The lead screw 296 is externally threaded with a sleeve 299 that slides through the interior of the sorting box 11, and the surface of the sleeve 299 is provided with a limiting block 2991 that restricts its rotation.

[0019] Specifically, first, the solar cell to be sorted is placed on the conveying frame 10, and the solar cell is conveyed to the inside of the detection box 13 by the conveying belt 17 for detection, and after the detection is completed, the detected solar cell is conveyed to the position of the sorting box 11 by the conveying belt 17, and the solar cell is unloaded to the chute 12 by the unloading assembly 50 and loaded to the inside of the sorting box 11 through the chute 12 to complete the sorting of the solar cell. It should be noted that the feeding, detection and unloading in the entire sorting process are recognized and controlled by the controller and sensor to ensure the accuracy of the sorting, and the operation belongs to the common knowledge in the art, so it is not described here. When the solar cell enters the inside of the sorting box 11, since the inclination direction and angle of the righting frame 22 and the chute 12 are consistent, the solar cell will directly slide into the inside of the righting frame 22. After the solar cell enters the righting frame 22, it collides with the righting frame 22 to make it displace backward in the first sliding groove 24. Until the sliding arm 221 on the righting frame 22 is displaced to the position of the second sliding groove 25, under the action of gravity, the righting frame 22 drives the solar cell to slide along the second sliding groove 25 to the bottom of the sorting box 11 and finally lay flat in the sorting box 11, so that the solar cell is not directly in contact with the bottom of the sorting box 11 and other solar cells when it is winded into the inside of the sorting box 11. Through the righting frame 22 as a buffer, the probability of damage due to impact after the solar cell falls into the inside of the sorting box 11 is reduced. At the same time, the righting frame 22 stacks multiple solar cells in a neat and spaced state, reducing the probability of damage due to impact of the protruding corners of the solar cell, and reducing the probability of scratching when the operator collects the solar cell. It is more convenient for the operator to collect the solar cell and take a single solar cell. The solar cell first slides into the inside of the righting frame 22 at the inclination angle of the chute 12, and then recovers to a stable state in the inside of the sorting box 11. Compared with directly conveying the solar cell to the inside of the sorting box 11, the range of impact and resistance of the corners of the solar cell is greatly reduced, further reducing the damage rate of the solar cell during sorting; Then the first spring 23 elastically resets to push the righting frame 22 in the inside of the storage cavity 21 to move upward to the horizontal position of the first sliding groove 24, and the righting frame 22 is pushed into the first sliding groove 24 by the supplement unit 29 to support the next solar cell. The limiting seat 222 can limit the righting frame 22 from falling out of the first sliding groove 24 and the second sliding groove 25 when sliding in the first sliding groove 24 and the second sliding groove 25. In this way, the sorting and collection of the solar cell are realized; In addition, when the solar cell hits the alignment frame 22, the alignment frame 22 hits the force bearing 26, so that the force bearing 26 pushes the limiting rod 28 to displace, and in the displacement process, the force bearing 26 pressurizes the second spring 27, and the second spring 27 absorbs the vibration generated by the solar cell hitting the alignment frame 22, thereby reducing the damage probability of the solar cell due to the impact, and through the impact, the limiting rod 28 is displaced to trigger the replenishment unit 29 to replenish the alignment frame 22 in real time; When the limiting rod 28 is displaced to push the rack 291 to displace synchronously, the rack 291 drives the rotating shaft 293 to rotate through the first gear 294, so that the rotating shaft 293 drives the toothed chain 298 to rotate through the second gear 295, and then the toothed chain 298 drives the third gear 297 to rotate, and the rotation of the third gear 297 drives the lead screw 296 to rotate, so that the lead screw 296 exerts a rotating force on the sleeve 299. Since the sleeve 299 is limited by the limiting block 2991 and cannot rotate, the rotating motion is converted into linear motion, so that the sleeve 299 is displaced towards the inside of the sorting box 11 and pushes the uppermost alignment frame 22 into the first sliding groove 24, completing the replenishment of the alignment frame 22.

[0020] As shown in Figure 5 With Figure 6 As shown, the inside of the alignment frame 22 is provided with a clamping assembly 30 for clamping and positioning the solar cell during alignment, the clamping assembly 30 includes a rubber capsule 32 glued to the inside of the alignment frame 22, and the rubber capsule 32 and the inside of the alignment frame 22 form a cavity 31 for loading carbon dioxide aqueous solution, the inside of the cavity 31 is rotationally connected with an agitator 34 through a rotating drum 33, and the inside of the rotating drum 33 is slidingly connected with a push rod 35 glued to the rubber capsule 32, the surface of the push rod 35 is fixedly connected with a first sliding block 36, and the inner wall of the rotating drum 33 is provided with a third sliding groove 37 matched with the first sliding block 36.

[0021] Specifically, when the solar cell enters the inside of the righting frame 22, it will squeeze the rubber capsule 32 so that the rubber capsule 32 shrinks, and the rubber capsule 32 pushes the push rod 35 to slide in the rotating drum 33, and then the first sliding block 36 on the push rod 35 slides along the third sliding groove 37 on the inner wall of the rotating drum 33 and drives the rotating drum 33 to rotate with the stirring blade 34, and the stirring blade 34 stirs the carbon dioxide aqueous solution in the container cavity 31 to make the carbon dioxide separate from the water and restore to the gaseous state, and as the carbon dioxide gas increases, the rubber capsule 32 also expands, and the expanded rubber capsule 32 clamps the solar cell, so that the solar cell is in a tense state when it slides to the bottom of the sorting box 11 with the righting frame 22, thereby reducing the gap between the solar cell and the righting frame 22, and reducing the impact swing amplitude of the solar cell when it falls, further reducing the damage probability of the solar cell, and as the righting frame 22 is stationary, the carbon dioxide gas is dissolved in water again, and at this time the rubber capsule 32 shrinks and restores, which does not affect the subsequent taking of the solar cell.

[0022] As shown in Figure 1 With Figure 7 As shown, the both sides of the slide 12 are provided with cleaning assemblies 40 for cleaning the surface thereof, the cleaning assembly 40 comprises a first magnet 41 fixedly connected to the front end of the righting frame 22, the both sides of the slide 12 are provided with fourth sliding grooves 43 for sliding of a sliding frame 44 and recesses 45 for loading of elastic folding air bags 46, and the sliding frame 44 and the elastic folding air bag 46 are glued together, the rear end of the sliding frame 44 is fixedly connected with a second magnet 42 magnetically attracted to the first magnet 41, and the both sides of the elastic folding air bag 46 are respectively provided with one-way pressure valves 47 penetrating through the slide 12 and the sliding frame 44.

[0023] Specifically, when the righting frame 22 moves to the top of the storage cavity 21, the first magnet 41 at the end thereof magnetically adsorbs the second magnet 42 on the sliding frame 44 through the sorting box 11, and then the replenishment unit 29 pushes the righting frame 22 to slide into the first sliding groove 24, so that the righting frame 22 drives the sliding frame 44 to slide into the fourth sliding groove 43 through the first magnet 41 and the second magnet 42, thereby squeezing the elastic folding air bag 46 with the sliding frame 44 to discharge the gas in the elastic folding air bag 46 through the one-way pressure valves 47 on the both sides of the slide 12, and blowing away the impurities on the surface of the slide 12 through the gas flow, avoiding the solar cell from being scratched by the particulate impurities such as dust when sliding through the slide 12, further reducing the damage probability of the solar cell during sorting, and then the righting frame 22 slides down along the second sliding groove 25 to separate the first magnet 41 from the second magnet 42, at this time the elastic folding air bag 46 restores to the expanded state under the elastic action of itself, and absorbs the external air into its interior through the one-way pressure valves 47 on the sliding frame 44, and the slide 12 is cleaned after each sorting, greatly reducing the probability of the particulate impurities such as dust adhering to the surface of the slide 12.

[0024] As Figure 1 With Figure 8 As shown in the figure, the unloading assembly 50 includes a mounting frame 51 fixedly mounted on the side of the conveying frame 10 and a second electric cylinder 52 mounted thereon, the output end of the second electric cylinder 52 is rotatably connected with an unloading roller 55 through an active arm 53 connected in a movable manner, the active arm 53 is provided with a driving motor 56 connected with the unloading roller 55, and one end of the active arm 53 is fixedly connected with the conveying frame 10 through a rotating seat 54, and the surface of the unloading roller 55 is provided with a limiting groove 57 for limiting the movement of the solar cell.

[0025] Specifically, when the solar cell is conveyed to the corresponding sorting box 11 after detection, the second electric cylinder 52 drives the active arm 53 to rotate around the connecting point of the rotating seat 54, the unloading roller 55 is lifted up through the rotation of the active arm 53, and one side of the solar cell is lifted up by the unloading roller 55. Since the surface of the unloading roller 55 is provided with the limiting groove 57 for limiting the position of the solar cell, the solar cell will not continue to move due to the inertia of the conveying frame 10 after being lifted up, and then the driving motor 56 drives the unloading roller 55 to rotate, and the solar cell is pushed into the chute 12 by the rolling of the unloading roller 55 and falls into the sorting box 11 for collection. The solar cell is always limited by the limiting groove 57 on the surface of the unloading roller 55 and the chute 12 during movement, so that each solar cell can be neatly stacked after falling into the sorting box 11, which is convenient for subsequent process treatment of the sorted solar cells.

[0026] As Figures 9-12 As shown in the figure, the detection box 13 and the conveying belt 17 are arranged on the conveying frame 10, the inside of the detection box 13 is fixedly connected with a visual detector 14, and the inside of the detection box 13 is movably connected with a detection probe array 15 through a first electric cylinder 16, the inside of the detection box 13 is provided with an adjusting assembly 60, the adjusting assembly 60 includes a limiting frame 61 fixedly connected to the inside of the detection box 13, fifth sliding grooves 62 are arranged on the inner walls of the front and rear ends of the detection box 13, first driving arms 63 are fixedly connected to the front and rear ends of the detection probe array 15, second driving arms 64 are slidably connected in the fifth sliding grooves 62, fourth gears 65 rotatably connected with the fifth sliding grooves 62 are engaged between the second driving arms 64 and the first driving arms 63, and the ends of the two second driving arms 64 away from the fourth gears 65 are fixedly connected with a supporting plate 66. The second driving arm 64 comprises a first arm body 641 and a second arm body 642, the upper end of the first arm body 641 is fixedly connected with a second sliding block 643, the lower end of the second arm body 642 is provided with a sixth sliding groove 644 matched with the second sliding block 643, and a third spring 645 is fixedly connected between the second sliding block 643 and the sixth sliding groove 644, and the elastic force of the third spring 645 is greater than the sum of the gravity of the first arm body 641 and the supporting plate 66.

[0027] Specifically, when the solar cell is transported into the detection box 13 for detection, whether the solar cell has cracks, scratches and the like is detected by the visual detector 14 in the detection box 13 first, and then the circuit of the solar cell is detected by the detection probe array 15. When the circuit of the solar cell is detected, the detection probe array 15 is pushed downward by the first electric cylinder 16, so that the probes on the detection probe array 15 are in contact with the grid bars on the solar cell. But when sorting and detecting solar cells of different thicknesses, the initial position of the detection probe array 15 needs to be frequently adjusted, which greatly affects the sorting and detection efficiency. Based on this, when the detection probe array 15 is lowered during detection, the first driving arm 63 is simultaneously lowered along the fifth sliding groove 62, the fourth gear 65 is rotated when the first driving arm 63 is lowered, the second driving arm 64 is raised by the rotation of the fourth gear 65, so that the second driving arm 64 drives the supporting plate 66 to rise, and the solar cell is lifted and rises synchronously after the supporting plate 66 rises, until the supporting plate 66 contacts the limiting frame 61. At this time, the probes on the detection probe array 15 are also in contact with the grid bars on the upper end of the solar cell. Through the clamping of the supporting plate 66 and the limiting frame 61 on the solar cell, it can avoid the deformation of the solar cell caused by extrusion during detection, which causes inaccurate detection data. At the same time, when the solar cell is too thick, the upper end of the solar cell contacts the limiting frame 61, and the probes on the detection probe array 15 have not contacted the solar cell. At this time, the first driving arm 63 continues to move downward, and the second driving arm 64 continues to move upward by the fourth gear 65, so that the second arm body 642 moves upward, and the first arm body 641 is limited by the supporting plate 66 and no longer moves. At this time, the first arm body 641 and the second arm body 642 are separated, the second sliding block 643 slides in the sixth sliding groove 644 and stretches the third spring 645, until the probes on the detection probe array 15 contact the grid bars on the solar cell, so that the solar cells of different thicknesses are detected, without the need to adjust the initial position of the detection probe array 15, and the sorting efficiency of the solar cells is improved.

[0028] As Figure 9 With Figure 13As shown, the conveying belt 17 includes a first belt body 171 and a second belt body 172, and the fourth spring 173 is fixedly connected between the first belt body 171 and the second belt body 172. The second belt body 172 is composed of multiple sections, each of which is fixedly connected with a rubber strip 174 on the left side and is provided with a movable slot 175 on the right side, and the rubber strip 174 is in telescopic connection with the movable slot 175.

[0029] Specifically, the solar cells to be sorted are placed on the conveying belt 17 in sequence, and after the solar cell panel contacts the conveying belt 17, the second belt body 172 is pressed downward under the action of gravity, so that the fourth spring 173 is contracted, and at the same time, the rubber strip 174 is stretched out of the outside of the movable slot 175. At this time, the second belt body 172 on which the solar cell is placed is recessed between the two adjacent second belt bodies 172, so that the solar cell is limited in the recessed position. The solar cell is conveyed to the detection box 13 by the conveying belt 17 for detection. During the conveying process, the solar cell is limited by the recessed position and will not be displaced due to equipment vibration. At the same time, when the solar cell is conveyed to the inside of the detection box 13, the conveying belt 17 stops conveying. At this time, the solar cell will not be displaced due to the inertia generated by the sudden stop of the conveying belt 17, so that the solar cell can be accurately stopped in a specific area inside the detection box 13, avoiding the detection data being affected due to the position deviation of the solar cell, improving the accuracy of detection during the sorting of the solar cell, and further limiting the sorting path of the solar cell through the recess on the conveying belt 17 and the limiting slot 57 on the surface of the discharging roller 55, to ensure that the solar cell can be neatly stacked after entering the inside of the sorting box 11.

[0030] A solar cell sorting method, comprising the following steps: S1: placing the solar cells to be sorted on the conveying belt 17 of the conveying frame 10, and conveying the solar cells to the inside of the detection box 13 by the conveying belt 17 for detection; S2: detecting the solar cells by the visual detector 14 and the detection probe array 15 in the detection box 13 to determine whether the solar cells have cracks and abnormal circuit conditions; S3: The detected solar cell is transported to the position of the sorting box 11 by the conveying belt 17, unloaded into the corresponding sorting box 11 by the unloading assembly 50 using the chute 12, and arranged in place by the aligning assembly 20. When the solar cell enters the sorting box 11, it directly slides into the aligning frame 22 due to the consistent inclination direction and angle of the aligning frame 22 and the chute 12. The solar cell hits the aligning frame 22 and displaces backward in the first sliding groove 24. The sliding arm 221 on the aligning frame 22 displaces to the position of the second sliding groove 25. Under the action of gravity, the aligning frame 22 drives the solar cell to slide along the second sliding groove 25 to the bottom of the sorting box 11 and finally lay flat in the sorting box 11. The solar cell does not directly contact the bottom of the sorting box 11 and other solar cells when it is wind-sorted into the sorting box 11. The aligning frame 22 reduces the damage probability of the solar cell due to impact after falling into the sorting box 11. At the same time, the aligning frame 22 stacks multiple solar cells in a neat and spaced state, reducing the damage probability of the solar cell due to impact of the protruding corners, reducing the scratching probability of the operator when collecting the solar cell, and facilitating the operator to take the single solar cell after collecting the solar cell. The solar cell first slides into the aligning frame 22 at the inclination angle of the chute 12, and then recovers to a stable state in the sorting box 11. Compared with directly transporting the solar cell into the sorting box 11, the range of impact and resistance of the corners of the solar cell is greatly reduced, further reducing the damage rate of the solar cell during sorting; Then the aligning frame 22 in the storage cavity 21 is pushed upward to the horizontal position of the first sliding groove 24 by the first spring 23, and the aligning frame 22 is pushed into the first sliding groove 24 by the replenishment unit 29 to support the next solar cell. The limiting seat 222 can prevent the aligning frame 22 from falling out of the first sliding groove 24 and the second sliding groove 25 during sliding. In this way, the solar cell is sorted and collected; In addition, when the solar cell hits the aligning frame 22, the aligning frame 22 hits the stress seat 26, which pushes the limiting rod 28 to displace. During the displacement process, the stress seat 26 compresses the second spring 27. The second spring 27 absorbs the vibration generated by the impact of the solar cell on the aligning frame 22, thereby reducing the damage probability of the solar cell due to impact. The limiting rod 28 is displaced by impact to trigger the replenishment unit 29 to replenish the aligning frame 22 in real time; When the limiting rod 28 is displaced, the rack 291 is synchronously displaced, the rack 291 drives the rotating shaft 293 to rotate through the first gear 294, the rotating shaft 293 drives the toothed chain 298 to rotate through the second gear 295, then the toothed chain 298 drives the third gear 297 to rotate, the third gear 297 drives the screw rod 296 to rotate, the screw rod 296 exerts a rotating force on the sleeve 299, since the sleeve 299 is limited by the limiting block 2991 and cannot rotate, the rotating motion is converted into linear motion, the sleeve 299 is displaced to the inside of the sorting box 11 and pushes the uppermost aligning frame 22 into the first sliding groove 24, the supplement of the aligning frame 22 is completed.

[0031] The above description is only the preferred embodiment of the present application, but the protection scope of the present application is not limited to this, any person skilled in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
