[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0033] Embodiment 1 is given by Figures 1 to 13 The present invention includes a U-shaped transmission groove 1. Transmission rollers 2 are rotatably installed at equal intervals inside the U-shaped transmission groove 1. An n-shaped frame 3 is installed at the top of the U-shaped transmission groove 1. A detection instrument body 4 is installed at the top inside the n-shaped frame 3. A vertical plate 5 is fixedly installed at one end of the U-shaped transmission groove 1. A vertical groove 6 is opened on one side of the vertical plate 5. A lifting inner cavity 7 is opened inside the vertical groove 6. A sliding card slot 8 is opened on one side of the lifting inner cavity 7. First sprockets 9 are installed at the upper and lower parts on the other side inside the lifting inner cavity 7. A first chain 10 is installed between the two first sprockets 9. A slider 11 is installed inside the sliding card slot 8. A rectangular groove 12 is opened in the middle of the slider 11. A square block 13 is installed inside the rectangular groove 12. A rotating connecting shaft 14 is rotatably installed on one side of the square block 13. A lifting arm rod 15 is installed on one side of the rotating connecting shaft 14. One end of the lifting arm rod 15 extends outside one side of the vertical plate 5 through the vertical groove 6. One end of the rotating connecting shaft 14 is rotatably connected to a connecting block 16. One end of the connecting block 16 is connected to the surface of the first chain 10. One end of the lifting arm rod 15 is installed with a rotating bar 17. Two clamping members 18 are symmetrically installed on one side of the rotating bar 17;

[0034] A gear 19 is fixedly installed in the middle of the rotating connecting shaft 14. A fixed rack 20 is fixedly installed at the upper part of the lifting inner cavity 7. A resisting bar 21 is installed on one side of the fixed rack 20. An inclined surface 22 is opened at the bottom of the resisting bar 21. A first motor 501 is installed on the surface of the vertical plate 5. The output end of the first motor 501 is fixedly connected to the middle of one of the first sprockets 9, so as to effectively perform lifting and transmission adjustment;

[0035] By starting the first motor 501, the two first sprockets 9 drive the first chain 10 to rotate. The rotation of the first chain 10 will pull the connecting block 16 upward. The upward movement of the connecting block 16 will drive the rotating connecting shaft 14 upward. The upward movement of the rotating connecting shaft 14 will drive the lifting arm rod 15, the gear 19, the square block 13 and the slider 11 upward, so that the slider 11 slides upward inside the sliding card slot 8. When the gear 19 moves to the fixed rack 20, it will be meshed with the fixed rack 20 and rotate. The rotation of the gear 19 will drive the rotating connecting shaft 14 to rotate 180 degrees. When the first chain 10 pulls the connecting block 16 to move to the opposite side of the fixed rack 20, such as Figure 4As shown, the connecting block 16 will pull the rotating connecting shaft 14 to move. The movement of the rotating connecting shaft 14 will drive the lifting arm rod 15, the gear 19, the square block 13 and the slider 11 to move. The movement of the square block 13 will move from one end of the rectangular groove 12 to the other end, and finally move downward through the first chain 10. And the downward moving gear 19 will not contact the fixed rack 20, so as to maintain the stability of the rotational adjustment;

[0036] One side of the bottom of the square block 13 is fixedly installed with a fixed block 23. A sliding inner groove 24 is opened at the top of the fixed block 23. An active slider 25 is installed inside the sliding inner groove 24. An active rack 29 is installed on the top of the active slider 25. The active rack 29 is movably connected to the gear 19. One side of the active slider 25 is fixedly connected with an extension pin 26. The extension pin 26 extends to the outside of one end of the fixed block 23 and is installed with a roller 27. The roller 27 contacts the inner wall of the lifting inner cavity 7. One end of the extension pin 26 is sleeved with a first spring 28. The two ends of the first spring 28 are respectively fixedly connected with one end of the sliding inner groove 24 and the active slider 25, so as to effectively maintain the stability of the rotating connecting shaft 14;

[0037] As Figure 9 shown, the active rack 29 is engaged with the gear 19, so that the rotating connecting shaft 14 will not rotate and remains stable; when the rotating connecting shaft 14, the gear 19 and the square block 13 move upward, it will drive the fixed block 23 to move upward. The upward movement of the fixed block 23 will make the roller 27 roll and contact the inner wall of the lifting inner cavity 7. When the roller 27 contacts the inclined surface 22 and the contact bar 21, it will make the roller 27 push the active slider 25 to move through the extension pin 26 and stretch the first spring 28. The movement of the active slider 25 will drive the active rack 29 to separate from the gear 19. After that, the gear 19 is engaged with the fixed rack 20 and can rotate; when the roller 27 separates from the contact bar 21, through the elastic recovery of the first spring 28, the active rack 29 will be engaged with the gear 19 again, and the gear 19 and the rotating connecting shaft 14 will not rotate and remain stable;

[0038] An inner cavity 30 is opened in the middle of the lifting arm rod 15. The rotating connecting shaft 14 penetrates through the inner cavity 30. And a second sprocket 31 is fixedly installed on the surface of the rotating connecting shaft 14 located inside the inner cavity 30. A rotating pin 32 is rotatably installed at one end of the inner cavity 30. A third sprocket 33 is fixedly installed on the surface of the rotating pin 32. A second chain 34 is installed between the third sprocket 33 and the second sprocket 31. One end of the rotating pin 32 extends to the outside of one side of the lifting arm rod 15 and is fixedly connected with the rotating bar 17, so as to effectively drive the rotating bar 17 to rotate 180 degrees;

[0039] When the rotating connecting shaft 14 rotates, the rotating connecting shaft 14 drives the second sprocket 31 to rotate. The rotation of the second sprocket 31 drives the rotating pin 32 to rotate through the second chain 34 and the third sprocket 33. The rotation of the rotating pin 32 drives the rotating bar 17 to rotate 180 degrees for adjustment.

[0040] Embodiment 2, on the basis of Embodiment 1, a baffle 35 is fixedly installed on one side of the lifting arm rod 15. Two grooves 36 are symmetrically opened at both ends on one side of the baffle 35. An I-shaped member 37 is installed between the inside of the groove 36 and the other side of the baffle 35. A second spring 38 is installed in the middle of the I-shaped member 37 and inside the groove 36. A moving wheel 39 is installed at one end of the I-shaped member 37. The moving wheel 39 is in contact with the surface of the vertical plate 5, so that the lifting arm rod 15 can be lifted and moved stably and effectively, and the lifting arm rod 15 can be horizontally finely adjusted and moved effectively.

[0041] When the lifting arm rod 15 is lifted and moved, it drives the rotating bar 17 and the clamping member 18 to move. At the same time, the movement of the lifting arm rod 15 drives the moving wheel 39 to roll on the surface of the vertical plate 5, so as to keep the lifting and moving of the lifting arm rod 15 stable.

[0042] When the first chain 10 pulls the connecting block 16 to move to the opposite side of the fixed rack 20 as Figure 4 shown, the connecting block 16 pulls the rotating connecting shaft 14 to move. The movement of the rotating connecting shaft 14 drives the lifting arm rod 15, the gear 19, the square block 13 and the slider 11 to move. The movement of the square block 13 moves from one end of the rectangular groove 12 to the other end, so that the lifting arm rod 15 is horizontally finely adjusted and moved. The horizontal fine adjustment movement of the lifting arm rod 15 squeezes the moving wheel 39, so that the moving wheel 39 pushes the I-shaped member 37 to move and compresses the second spring 38, so that the lifting arm rod 15 can maintain effective stability.

[0043] An adjustment groove 41 is opened on one side of the rotating bar 17. A bidirectional threaded shaft 42 is installed inside the adjustment groove 41. A second motor 40 is installed at the bottom of the rotating bar 17. One end of the second motor 40 is connected to one end of the bidirectional threaded shaft 42. Threaded moving blocks 43 are installed on both sides of the bidirectional threaded shaft 42. Two clamping members 18 are installed on one side of the two threaded moving blocks 13. Each of the two clamping members 18 includes a pair of rubber clamping strips 44. A cross bar 45 is fixedly installed at equal intervals between one side of the pair of rubber clamping strips 44. A cross bar 46 is fixedly installed between the middle parts of the cross bars 45. One end of the cross bar 46 is fixedly connected to one side of the threaded moving block 43, so as to effectively clamp and fix the photovoltaic cell for lifting movement and turning adjustment; A notch 47 is opened on one side of the bottom of the U-shaped transmission groove 1. The second motor 40 is located inside the notch 47.

[0044] After the photovoltaic cell passes through the inside of the n-shaped frame 3 by the rolling of the transmission roller 2 and is detected by the detection instrument body 4, it will move between the two clamping members 18. Then, the second motor 40 is started, so that the second motor 40 drives the bidirectional threaded shaft 42 to rotate. The rotation of the bidirectional threaded shaft 42 will cause the two threaded moving blocks 43 to move relatively. The two relatively moving threaded moving blocks 43 will drive the cross bar 46 and the cross strip 45 to move, and finally the two pairs of rubber clamping strips 44 will clamp and fix the photovoltaic cell; After that, the photovoltaic cell is turned over by the upward movement of the lifting arm rod 15 and by rotating the rotating bar 17 by 180 degrees; The final downward movement and the release of the clamping of the two pairs of rubber clamping strips 44 enable the photovoltaic cell to be effectively placed on the surface of the transmission roller 2. At the same time, the reverse rotation of the transmission roller 2 enables the other side of the photovoltaic cell to pass through the detection instrument body 4 again for detection.

[0045] Embodiment 3, on the basis of Embodiment 1, one end of each of the transmission rollers 2 extends to the outside of one side of the U-shaped transmission groove 1 and is fixedly provided with a worm gear 48. A forward and reverse motor 49 is installed on one side of the U-shaped transmission groove 1. A worm 50 is installed between the output end of the forward and reverse motor 49 and one side of the U-shaped transmission groove 1. The worm gears 48 are all meshed with the worm 50, so as to effectively transmit and move the photovoltaic cell for monitoring; By starting the forward and reverse motor 49, the worm 50 rotates to drive the worm gear 48 to rotate. The rotation of the worm gear 48 will drive the transmission roller 2 to rotate, and the rotation of the transmission roller 2 will transmit and move the placed photovoltaic cell.

[0046] The automatic detection device applicable to large-size photovoltaic cells can effectively perform automatic turning-over operation on the photovoltaic cells, thus facilitating the detection of the photovoltaic cells by the detection device. At the same time, it also effectively improves the detection efficiency and speed of the photovoltaic cells. At the same time, the automatic turning-over operation of the photovoltaic cells is simple, convenient, stable and reliable. Therefore, the practicability and performance of the automatic detection device applicable to large-size photovoltaic cells can meet the usage needs of people.
