[0002] As the core element of optical system, the performance of optical lens directly affects the key indicators such as imaging quality and energy transmission, and surface defects (scratches, bubbles) will cause light scattering and reduce imaging contrast; face shape error (such as RMS value exceeding the standard) will introduce wavefront distortion and cause aberrations such as spherical aberration and coma, etc. In order to ensure that it meets the design requirements, the detection link is essential.
[0003] In the existing precision optical detection, the performance of lens detection fixture directly affects the measurement accuracy and repeatability, and the traditional optical lens fixture design often lacks sufficient flexibility and universality.

This cumbersome operation process not only greatly reduces the work efficiency, but also easily causes potential damage to the lens due to the instability of human operation, affecting the reliability of the detection result.

[0007] Preferably, the shaft rotating seat is rotatably connected with the side wall of the platform on both sides, and is driven by the driving assembly. The existing lens detection mechanism cannot rotate and adjust the lens. During the detection process of the lens, the lens needs to be rotated. Rotating the lens can adjust the relative angle of the surface of the lens and the light source and the camera, avoid the mirror reflection light covering the defect area, and ensure that the imaging system can clearly capture scratches, pockmarks and other tiny defects. Through rotating 360° frame-by-frame shooting or scanning, the whole lens circumferential direction is detected without dead angle, and the edge area is not missed under the fixed angle. However, the existing detection mechanism does not have a rotating function, and needs to be matched with artificial or other auxiliary rotating mechanisms, which is time-consuming and laborious. In view of the problems, the utility model adopts an integrated rotating mechanism, drives the shaft rotating seat to rotate through the driving assembly, and drives the lens to rotate, so that the imaging system can clearly capture scratches, pockmarks and other tiny defects.
[0008] Preferably, the driving assembly comprises a worm gear, the shaft of the worm gear is fixedly connected with the side surface of the shaft rotating seat, the surface of the worm gear is engaged with a worm, and the two ends of the worm are both connected with a worm seat through a bearing, the worm seat is fixedly connected with the surface of the platform, the worm is driven by a worm rotating motor, the worm rotating motor drives the worm to rotate, the worm drives the worm gear to rotate, and the shaft rotating seat is driven to rotate, the worm gear and worm structure have self-locking property, the rotating angle of the shaft rotating seat is facilitated to be controlled, the rotating angle of the lens is controlled, and the detection precision of the lens is improved.
[0009] Preferably, the surface of the clamp is covered with a damping rubber pad. The damping rubber pad can effectively prevent scratches, wear or extrusion damage to the peripheral surface of the lens during clamping, which is particularly important for protecting the appearance and performance of the lens, improves the yield of the lens, and the damping rubber pad has good friction performance, can increase the friction force between the clamp and the lens, thereby ensuring that the clamping is more firm, preventing the lens from shaking during the detection process, and improving the detection precision.
[0010] Preferably, the shock-absorbing rubber pad surface array is provided with anti-skid lines, which further effectively prevent the lens from deviating during detection clamping by increasing the friction between the shock-absorbing rubber pad and the lens. Advantages
[0011] In the existing precise optical detection, the performance of the lens detection clamp directly affects the measurement precision and repeatability, and the traditional optical lens clamp design often lacks sufficient flexibility and universality. When facing lenses of different shapes and sizes, the operator needs to spend a lot of time and effort to fine-tune the position and posture of the clamp, and also needs to prevent the clamp from causing wear to the lens peripheral surface due to rapid adjustment. Such a cumbersome operation process not only greatly reduces the work efficiency, but also easily causes potential damage to the lens due to the instability of human operation, affecting the reliability of the detection result. To solve such problems, the utility model adopts a shock-absorbing mechanism. When the clamp contacts the lens peripheral surface, the lens transmits the pressure to the damping spring shock absorber through the connecting rod. The spring inside the damping spring shock absorber deforms, absorbing and storing part of the energy. The oil or gas inside the damper generates resistance through the viscous liquid encapsulated inside, to hinder the movement of the connecting rod, converting the energy generated by the pressure into heat energy for dissipation, reducing the instantaneous pressure on the lens peripheral surface when the clamp clamps the lens, so that the operator does not need to spend a lot of time and effort to fine-tune the position and posture of the clamp, preventing the clamp from causing wear to the lens peripheral surface due to rapid adjustment, and improving the work efficiency and the yield of the lens.
