The working principle of the optical lens detector is as follows:
when in use, the optical lens is firstly opened and placed in the placement ring 64 and contacted with the rotating shaft 72 and the roller shaft 65, and the placement ring 64 is positioned at the position of the support plate 63 at the side far away from the servo motor 61;
then the sealing strips 5 are mutually attached to close the light shielding plate 4, in the process of closing the light shielding plate 4, the side wall of the light shielding plate 4 can push the switch block 82 and the release block 96 to slide towards the inside of the side wall of the cylinder 1, and the switch spring 83 and the release spring 95 are extruded until the switch block 82 and the release block 96 are opposite to the inserting groove 84, at the moment, the switch block 82 and the release block 96 can enter the inserting groove 84 under the action of the switch spring 83 and the release spring 95 to lock the light shielding plate 4, and at the moment, the light shielding plate is in a night state;
the light source 2, the imager 3 and the servo motor 61 can then be activated so that the image emitted by the light source 2 is imaged on the imager 3 through the optical lens;
the rotation of the servo motor 61 drives the threaded rod 62 to rotate, so that the placement ring 64 slides towards the servo motor 61, in the sliding process of the placement ring 64, the torsion roller 71 starts to rotate to release the connection pull rope 73, so that the rotation shaft 72 rotates, the rotation of the rotation shaft 72 rotates under the rotation action of the rotation shaft 72 and the rolling action of the roller shaft 65, the imaging state of the optical lens on the imager 3 through the light source 2 is changed, the distance between the optical lens and the light source 2 is gradually shortened when the placement ring 64 moves, and the resolution of the optical lens at night is detected;
when the bottom of the placement ring 64 is about to slide to the top of the release magnetic plate 93, the torsion roller 71 fully releases the connection pull rope 73, in the process that the connection pull rope 73 slides upwards to compress the release magnetic plate 93, the release magnetic plate 93 slides downwards along the inner side wall of the fixed box 91 under the action of the magnetic force of the placement ring 64 to squeeze the release spring 95, the downward sliding of the release magnetic plate 93 pulls the release pull rope 94 to enable the release pull rope 94 to pull the release block 96 to be separated from the inserting groove 84 and compress the release spring 95, in the process, the placement ring 64 still slides due to the complete release of the connection pull rope 73, the slide plate 74 slides upwards to compress the retraction spring 75 through the connection pull rope 73 in the process that the placement ring 64 slides, the upward sliding of the slide plate 74 pulls the switch pull rope 81 to enable the switch pull rope 81 to pull the switch block 82 to be separated from the inserting groove 84 and compress the switch spring 83, and in the process that the release block 96 and the switch block 82 are pulled out of the inserting groove 84, the light shielding plate 4 is automatically opened in a daytime state;
after the light shielding plate 4 is opened, the servo motor 61 is reversed to drive the threaded rod 62 to be reversed, so that the placement ring 64 is far away from the position where the support plate 63 on one side of the servo motor 61 is located, in the process, when the placement ring 64 is separated from the position where the release magnetic plate 93 is located, the release magnetic plate 93 can slide upwards under the action of the fixed spring 92, the pulling state of the release pull rope 94 is lost, and the release block 96 is reset under the action of the release spring 95;
in this process, the sliding plate 74 will slide downwards under the action of the rotation-retracting spring 75, the tension state of the switch stay cord 81 is lost, so that the switch block 82 is reset under the action of the switch spring 83, after the switch block 82 is reset, the placement ring 64 continues to slide, the torsion roller 71 will wind the connection stay cord 73, the torsion roller 71 drives the rotation shaft 72 to rotate, the optical lens rotates under the rotation action of the rotation shaft 72 and the rolling action of the roller shaft 65, the imaging state of the optical lens on the imager 3 through the light source 2 is changed, and the distance between the optical lens and the light source 2 is gradually shortened when the placement ring 64 moves, so that the resolution of the optical lens at night is detected;
after the placement ring 64 is reset, the resolution and the light transmittance of the optical lens can be accurately detected through imaging on the imager 3.
