When the support box 6 and the support plate 7 move to the detection station, the CCD imager 4 is driven to move horizontally by the adjustment member, so that the CCD imager 4 moves horizontally to a preset position, and at the same time, the damping push structure drives several movable seats 11 to move toward the first rotating shaft 8, so that several positioning columns 10 clamp the photoelectric detector located at the detection station, so that the physical center of the photoelectric detector coincides with the first rotating shaft 8, and the first rotating shaft 8 and the support plate 7 are driven to rotate by the driver, so that the photoelectric detector located at the top of the support plate 7 The photoelectric detector rotates synchronously, and the mark at the center of the photoelectric detector chip rotates synchronously. The display 3 displays the track formed by the chip mark photographed by the CCD imager 4. If the coaxiality error between the shell and the chip is 0, the chip center coincides with the physical center of the photoelectric detector, and the track formed by the chip mark is a point. If the coaxiality error between the shell and the chip is not 0, it means that the chip center does not coincide with the physical center of the photoelectric detector. When the photoelectric detector rotates, the track formed by the chip mark is a circle, and the larger the radius of the circle, the larger the coaxiality error. The staff can place the photoelectric detector to be tested on the support plate 7 located at the loading station, and there is no need to wait for the CCD imager 4 to finish shooting the test, which reduces the time interval between two tests and improves the test efficiency. The self-rotation structure drives the support frame 5 and the support box 6 to rotate, and the first support column 15 located under the support box 6 moves to the top of the support bar 30. As the support box 6 continues to rotate, the bottom end of the first support column 15 slides from the support bar 30 to the first bracket 31, and the first support column 15, the first support portion 14 and the movable ring 13 move up. The first compression spring 20 is in a compressed state. The first compression spring 20 applies pressure to the damping plate 17 so that the damping plate 17 is elastically pressed on the support sleeve 12. When the movable ring 13 moves up, the damping plate 17 drives the support sleeve 12 to move up synchronously through friction. The bottom end of the third support column 51 slides on the inclined surface of the support sleeve 12, and the third support column 51 drives the movable seat 11 to move toward the first rotating shaft 8. The prism 44 slides relative to the groove 45 slides, the second compression spring 46 is in a compressed state, and the movable seat 11 drives the positioning column 10 to move toward the photoelectric detector located on the top of the support plate 7. When several positioning columns 10 clamp the photoelectric detector, as the movable ring 13 continues to move upward, the damping plate 17 cannot drive the support sleeve 12 to move upward synchronously through friction, and the support sleeve 12 maintains the height at this time. The positioning column 10 stops moving, and the movable ring 13 and the damping plate 17 slide upward relative to the support sleeve 12. When the bottom end of the first support column 15 contacts the top of the first bracket 31, the first support column 15 and the movable ring 13 move up to the highest position. At this time, the support plate 7 and the support box 6 are located at the detection position. After the detection is completed, the self-rotation structure drives the support frame 5 and the support box 6 to rotate continuously. The support column 15 slides over the first bracket block 31 and the support bar 30 respectively, and the first bracket block 31 and the support bar 30 no longer support the first support column 15 and the movable ring 13, and the second compression spring 46 pushes the movable seat 11 to move in the opposite horizontal direction, so that the movable seat 11 and the positioning column 10 are restored to the initial position, and the support sleeve 12 and the movable ring 13 move downward due to their own gravity, and the bottom of the support sleeve 12 first contacts the bottom inner wall of the support box 6. As the support box 6 continues to rotate, the fixed column 32 moves to the bottom of the second connecting plate 35, and the fixed column 32 slides from the second connecting plate 35 to the bottom of the second bracket block 34, and the second bracket block 34 pushes the fixed column 32 and the first support column 15 to descend relative to the support sleeve 12, and finally the fixed column 32, the first support column 1 5 and the movable ring 13 are lowered to the lowest position relative to the support sleeve 12, the bottom of the movable ring 13 contacts the bottom inner wall of the support box 6, the support sleeve 12, the movable ring 13 and the first support column 15 are reset to the initial position relative to the support box 6, the staff drives the two adjacent nuts 29 to rotate so that the two adjacent nuts 29 no longer clamp the first fixed plate 28, the design of the through hole 43 facilitates the staff to drive the nut 29 to rotate, the first fixed plate 28 is no longer fixed relative to the screw rod 27, the staff drives the pressing ring 25 and the first fixed plate 28 to move in the vertical direction so that the top of the second support column 23 slides on the inclined surface of the pressing ring 25, the pressing ring 25 pushes the second support column 23, the first connecting plate 24 and the movable plate 18 to move toward the damping plate 17,The spacing between the movable plate 18 and the damping plate 17 is changed, thereby adjusting the initial length of the first compression spring 20, changing the pressure applied by the first compression spring 20 to the damping plate 17, thereby adjusting the friction between the damping plate 17 and the support sleeve 12. When the movable plate 18 moves, the guide block 22 slides in the guide groove 21. When there is no need to adjust the position of the movable plate 18, the staff drives the two adjacent nuts 29 to rotate so that the two adjacent nuts 29 clamp the first fixed plate 28, and the first fixed plate 28 and the pressing ring 25 are fixed relative to the screw rod 27 and the movable ring 13; The second rotating shaft 36 and the support frame 5 are driven to rotate by the first motor 37, and the support frame 5 can drive the support box 6 to rotate above the operating table 1, and the support box 6 drives the roller 39 to roll on the top of the operating table 1 through the fixed frame 38. The design of the fixed frame 38 and the roller 39 allows the support box 6 to move smoothly on the operating table 1. When the support box 6 moves to the inspection station, the support box 6 drives the first damping plate 40 to move to the top of the second damping plate 42 through the first rotating shaft 8, and at this time, the bottom of the first damping plate 40 and the top of the second damping plate 42 are in contact, and the second motor 41 drives the first damping plate 40 to move to the top of the second damping plate 42. The second damping disk 42 is driven to rotate, and the second damping disk 42 can drive the first damping disk 40, the first rotating shaft 8 and the supporting disk 7 to rotate through the friction force. At this time, the first rotating shaft 8 drives the bottom end of the third supporting column 51 to slide on the inclined surface of the supporting sleeve 12 through the prism 44 and the movable seat 11, and the mounting seat 47, the electric push rod 49 and the CCD imager 4 are driven to rotate through the third motor 48 to change the position of the CCD imager 4. At the same time, the electric push rod 49 drives the CCD imager 4 to move horizontally relative to the mounting seat 47, so that the CCD imager 4 can be moved horizontally to a preset position.
