The two gear members 319 are respectively engaged with the two gear ring plates 323; three guide grooves 320 are provided on each of the two centering bases 306, and three movable guide blocks 314 are provided on each of the two flat screw plates 321. The multiple movable guide blocks 314 are respectively provided on the inner walls of the multiple guide grooves 320, and the outer walls of one side of the multiple movable guide blocks 314 are fixedly connected. The limiting thin plate 325 and the outer walls of one side of the multiple movable guide blocks 314 are fixedly connected with a connecting belt 317, one end of the multiple connecting belts 317 are respectively fixedly connected to the outer walls of the two elastic inner ring frames 316, and the interior of the two centering bases 306 is provided with a telescopic airbag 324, the outer walls of the two telescopic airbags 324 are fixedly connected with a connecting tube 307, one end of the two connecting tubes 307 is provided with an air pump body 308, the two air pump bodies 308 are respectively provided on the outside of the two centering bases 306, one of the centering bases 306 is provided with three grooves, and the inside of the three grooves is provided with a UV curing head 315.

At the same time, when in use, the elastic inner ring frame 316 can also apply a certain clamping force to the outside of the optical lens when it is in a horizontal state, and the clamping force in multiple directions is the same, so that the optical lens can be in the center of the elastic inner ring frame 316, reducing the centering adjustment degree of the optical lens, and the elastic inner ring frame 316 can adapt to optical lenses of different sizes when in use.

Then, the electric lifting rod 608 drives the fixed suction cup 610 to reset, and the electric telescopic rod 601 and the electric rod member 604 are started again, so that the device drives the optical lens to move above or below the centering base 306 (before moving to the bottom, the flip motor 605 is operated to drive the flip bracket to flip), and then the electric lifting rod 608 is operated again to set the optical lens inside the centering base 306; In a specific application scenario, the picking and loading module 6 is suitable for the centering and loading link of optical lenses, that is, the picking and loading module 6 can automatically pick up and load optical lenses when in use to increase the operation convenience of the device.

At this time, the bidirectional motor 403 is started, and the bidirectional motor 403 drives the two linkage wheels 412 to rotate, and further cooperates with the transmission belt 404 to drive the two transmission wheels 406 to rotate, so that the two cleaning soft rollers 405 rotate and clean the centering area of the optical lens.

[0025] A method for centering an aspheric optical lens based on laser detection, using the aspheric optical lens centering device based on laser detection as described above, comprises the following steps: Step 1: Place the optical lens on the mounting plate 408. Drive the mounting plate 408 with the drive motor 409 to rotate, so that the optical lens and the two cleaning rollers 405 are on the same axis. Then, start the bidirectional motor 403 to rotate the two linkage wheels 412, and further drive the two transmission wheels 406 to rotate, so that the two cleaning rollers 405 rotate to clean the optical lens. Step 2: After cleaning, the electric telescopic rod 601 and the electric rod 604 are operated to move the fixed suction cup 610 to the optical lens, and the electric lifting rod 608 is started. The electric lifting rod 608 drives the negative pressure pump 609 and the fixed suction cup 610 to rise and fall until the fixed suction cup 610 contacts the optical lens. At this time, the negative pressure pump 609 is operated, so that the fixed suction cup 610 adsorbs and fixes the optical lens. Then, the electric lifting rod 608 drives the fixed suction cup 610 to reset, and the electric telescopic rod 601 and the electric rod 604 are started again, so that the device drives the optical lens to move above or below the centering base 306 (before moving to the bottom, the flip motor 605 is operated to drive the flip bracket to flip), and then the electric lifting rod 608 is operated again to set the optical lens inside the centering base 306 to complete the lens loading; After the optical lens is set inside the centering base 306, the servo motor 318 is started, and the gear part 319 is driven to rotate by the servo motor 318. Since the gear part 319 is meshed with the gear ring plate 323, the servo motor 318 can drive the gear ring plate 323 to rotate, and then the gear ring plate 323 drives the rotating ring part 322 and the plane screw plate 321 to rotate, so that the plane screw plate 321 drives the movable guide block 314 to move inside the guide groove 320, and further drives the limiting thin plate 325 to approach the center of the centering base 306, and at the same time relaxes the connecting belt 317 and restores the elastic inner ring frame 316. Then the air pump body 308 is started, and the air pump body 308 is connected through the connecting pipe 307. The gas is transported to the inside of the telescopic airbag 324 and expands it, thereby driving the optical lens to move inside the centering base 306 and gradually approaching the limiting plate 325. As the optical lens moves, the elastic inner ring frame 316 will contact its surface and apply a certain clamping force to its outside to ensure that the optical lens is in the center of the elastic inner ring frame 316 until the optical lens contacts the limiting plate 325. At this time, the thrust of the telescopic airbag 324 and the cooperation of the limiting plate 325 can make the optical lens in a horizontal state. At this time, the laser measuring instrument body 5 is started, and the electric push rod 301, the horizontal push rod 305 and the longitudinal push rod 311 are started according to the laser measurement data to adjust the positions of the upper and lower optical lenses until the centering is completed.
