[0030] When positioning the lens, first fix the optical lens through the clamping assembly, then hold the U-shaped operating panel and unlock the limit of the slider by the limit assembly. At this time, with the cooperation of the slider, two sets of telescopic shafts and the card block, the U-shaped operating panel can be used to control the positioning plate and the adjustment plate to move quickly in all directions. When the optical lens on the adjustment plate and the fine-tuning plate reaches the specified position, stop controlling the movement of the U-shaped operating panel, and use the limit assembly to limit the adjustment plate so that the adjustment plate no longer moves. At this time, the rapid coarse adjustment process is completed, and then the fine-tuning knob is used to control the position of the fine-tuning plate, so that the optical lens can be positioned more accurately. After positioning, the eccentricity detection process of the optical lens is realized with the cooperation of the electric lifting mechanism, the light source assembly, the camera assembly and the zoom lens assembly. It can be seen that through the technical solution of the present invention, the adjustment efficiency of the coarse adjustment of the optical lens positioning can be greatly improved, and the operation is more direct and convenient.

[0031] As a preferred embodiment of the above, the limit assembly includes a limit box 15, a micro servo motor 16, a turntable 17 and two groups of limit columns 18. The limit box 15 is installed at the front end of the slider 9. A limit cavity is arranged inside the limit box 15. The micro servo motor 16 is installed at the right end of the limit box 15.

The turntable 17 is located in the limit cavity and is connected to the output end of the micro servo motor 16. The other end of the turntable 17 is rotatably connected to the limit cavity. The top and rear ends of the turntable 17 are both provided with arc claws. 19, the rear end of the limit cavity is connected with the front telescopic hole and is provided with a first extension hole, the top of the limit cavity is penetrated with a second extension hole, two groups of limit posts 18 slide through the first extension hole and the second extension hole respectively, the outer ends of the two groups of limit posts 18 are respectively in close contact with the top of the sliding hole and the side wall of the front telescopic shaft 10, the inner ends of the two groups of limit posts 18 are respectively in close contact with the outer walls of the arc surface of the two groups of arc-shaped claws 19, the micro servo motor 16 is equipped with a first forward switch 20 and a first reverse switch, and the first forward switch 20 and the first reverse switch are both installed on the top of the U-shaped operating panel 11;

[0032] When operating the U-shaped operating panel, the user can directly use the first forward switch and the first reverse switch of the U-shaped operating panel to control the forward and reverse rotation of the micro servo motor. The rotation angle of the micro servo motor is set in advance. When the micro servo motor rotates forward, the micro servo motor will drive the turntable to rotate, so that the two sets of arc-shaped claws on the turntable push the two sets of limit columns to move toward the outside of the limit box respectively, and the two sets of limit columns will be pressed against the side walls of the sliding hole and the side walls of the front telescopic shaft respectively. At this time, the coarse adjustment limit process of the optical lens is completed. When the micro servo motor is controlled to reverse, the two sets of limit columns are no longer pushed, and the limit is released. Through this limit component, the user can easily limit or release the coarse adjustment position of the optical lens when operating the U-shaped operating panel with one hand, which greatly improves the convenience of operation and improves the coarse adjustment efficiency.

[0034] By making the U-shaped operating panel longer, it can wrap around one side of the positioning panel and be close to the adjustment panel. Then the U-shaped operating panel can be used as a mounting substrate for wiring the micro servo motor and the first forward switch or the first reverse switch, and the circuit can be installed inside the U-shaped operating panel, so that the circuit can be more concealed, thereby improving the appearance of the device.

[0035] As a preferred embodiment of the above, the clamping assembly includes two groups of clamping plates 21, a first micro motor 22 and a rotating plate 23. An auxiliary hole is provided in the middle of the front end of the fine-tuning plate 14. The first micro motor 22 is installed at the top of the auxiliary hole. The output end of the first micro motor 22 rotates through the fine-tuning plate 14 and extends to the upper side of the fine-tuning plate 14. The output end of the first micro motor 22 is connected to the middle of the bottom end of the rotating plate 23. A power assembly is provided at the rear side of the top end of the rotating plate 23. The power assembly is provided with two power blocks 24. The two groups of clamping plates 21 are respectively installed on the two groups of power blocks 24 and the two groups of clamping plates 21 are in sliding contact with the rotating plate 23. The first micro motor 22 is equipped with a start switch, which is installed at the right end of the U-shaped operating panel 11.

[0036] By setting the clamping assembly to electric adjustment, the power assembly can drive the two sets of clamps to quickly clamp the optical lens, greatly improving the installation efficiency of the optical lens. At the same time, the first micro motor and the rotating plate can cooperate to make the optical lens rotate flexibly during the detection process, and the optical lens is located at the rotation center of the rotating plate, making the detection process more accurate, reliable and easy to operate.

[0037] As a preferred embodiment of the above, the power assembly includes a micro double-headed motor 25, which is installed in the middle of the rear side of the top of the rotating plate 23, and the two output ends of the micro double-headed motor 25 are provided with threaded rods 26, and the thread directions of the two groups of threaded rods 26 are opposite, and the two groups of power blocks 24 are provided with threaded holes, and the two groups of power blocks 24 are respectively threadedly connected with the two groups of threaded rods 26, and the micro double-headed motor 25 is equipped with a second forward switch 27 and a second reverse switch, and the second forward switch 27 and the second reverse switch are both installed at the right end of the U-shaped operating panel 11;

[0038] The cooperation of the micro double-headed motor, two sets of threaded rods and two sets of power blocks makes the movement process of the two sets of clamps more synchronized, greatly improves the positioning accuracy of the optical lens, and optimizes the clamping structure. The structure of the micro double-headed motor is simpler and more reliable. Moreover, the second forward switch and the second reverse switch of the micro double-headed motor are installed at the right end of the U-shaped operating panel, so that the user can operate the micro double-headed motor with one hand, further improving the convenience of operation.

[0039] As a preferred embodiment of the above, a protective cover 28 is provided at the rear side of the top end of the rotating plate 23, and the micro double-headed motor 25, two sets of threaded rods 26 and two sets of power blocks 24 are all located in the protective cover 28;

[0040] The micro double-headed motor, two sets of threaded rods and two sets of power blocks are wrapped by a protective cover, which improves the aesthetics of the equipment.

[0041] As a preferred embodiment of the above, both sets of clamping plates 21 are configured as V-shaped clamping plates 21;

[0042] The shape of the splint is set to be a V-shaped splint, and the structural characteristics of the V-shaped splint can be used to limit the optical lens in the middle of the two groups of splints, which greatly reduces the probability of the two groups of optical lenses offset between the two groups of splints and improves the reliability of positioning.

[0043] As a preferred embodiment of the above, a stabilizing rod 29 is further included. A stabilizing hole is provided through the left end of the positioning hole of the positioning plate 7.

[0044] With the cooperation of the stabilizing rod and the stabilizing hole of the positioning plate, the coarse adjustment movement process of the adjustment plate in the middle of the positioning plate is made more stable.

[0045] As a preferred embodiment of the above, a non-slip pad 30 is provided on the right side of the top of the U-shaped operating panel 11;

[0046] The design of the anti-slip pad can greatly reduce the probability of your hands slipping on the U-shaped operating panel when operating it, significantly improving the use effect.

[0047] The present invention provides an eccentricity detection device for an optical lens. When the optical lens is in operation and is positioned, the optical lens is first fixed by a clamping assembly, and then the U-shaped operating panel is held and the limit assembly on the slider is released. When operating the U-shaped operating panel, the user can directly use the first forward switch and the first reverse switch of the U-shaped operating panel to control the forward and reverse rotation of the micro servo motor. The rotation angle of the micro servo motor is set in advance. When the micro servo motor rotates forward, the micro servo motor drives the turntable to rotate, so that the two groups of arc-shaped claws on the turntable respectively push the two groups of limit columns to move to the outside of the limit box, and the two groups of limit columns are respectively pressed against the side wall of the sliding hole and the side wall of the front telescopic shaft. At this time, the coarse adjustment limit process of the optical lens is completed, and then the slider and the two groups of telescopic shafts are adjusted. With the cooperation of the card block, the U-shaped operating panel can be used to control the positioning plate and the adjustment plate to move quickly in all directions. When the optical lens on the adjustment plate and the fine-tuning plate reaches the specified position, the U-shaped operating panel is stopped from moving, and the limit assembly is used to limit the adjustment plate so that it no longer moves. When the micro-servo motor is controlled to reverse, the two sets of limit columns are no longer pushed, and the limit is released. Through this limit assembly, the user can easily limit or release the coarse position of the optical lens when operating the U-shaped operating panel with one hand. At this time, the rapid coarse adjustment process is completed, and then the fine-tuning knob is used to control the position of the fine-tuning plate, so that the optical lens can be positioned more accurately. After positioning, the eccentricity detection process of the optical lens is realized with the cooperation of the electric lifting mechanism, the light source assembly, the camera assembly and the zoom lens assembly.
