The longitudinal rail support plate 309 and one side of the two horizontal rail support plates 303 are fixedly connected with a mounting piece 312. The longitudinal platform 310 and one side of the two horizontal platforms 304 are fixedly connected with a fixing piece 313. The three mounting pieces 312 are respectively provided with a longitudinal push rod 311 and two horizontal push rods 305. The output ends of the longitudinal push rod 311 and the two horizontal push rods 305 are fixedly connected with one side of the three fixing pieces 313. The two centering bases 306 are arranged on the opposite sides of the two horizontal platforms 304. The two centering bases 306 are provided with a rotating ring piece 322. One side of the two rotating ring pieces 322 is fixedly connected with a gear ring plate piece 323. The other side of the two rotating ring pieces 322 is fixedly connected with a plane screw plate 321. The two centering bases 306 are provided with a servo motor 318. The output shafts of the two servo motors 318 are connected with a gear piece 319 through a shaft coupling. The two gear pieces 319 are engaged with the two gear ring plate pieces 323. The two centering bases 306 are provided with three guide grooves 320. The two plane screw plates 321 are provided with three movable guide blocks 314. The six movable guide blocks 314 are arranged on the inner walls of the six guide grooves 320. One side of the six movable guide blocks 314 is fixedly connected with a limiting thin plate 325.

[0039] Specifically, when the optical lens is set inside the centering base 306, the servo motor 318 is started to drive the gear part 319 to rotate. Since the gear part 319 is engaged with the gear ring plate part 323, the servo motor 318 can drive the gear ring plate part 323 to rotate, and further drive the rotating ring part 322 and the flat screw plate 321 to rotate, so that the flat screw plate 321 drives the movable guide block 314 to move in 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, the connecting belt 317 is loosened, and the elastic inner ring frame 316 restores. Then the air pump body 308 is started, and the air pump body 308 sends gas to the inside of the stretchable air bag 324 through the connecting pipe 307, and makes it expand, so as to drive the optical lens to move inside the centering base 306, and gradually approach the limiting thin plate 325. With the movement of the optical lens, the elastic inner ring frame 316 will contact the surface thereof and exert a certain clamping force on the outside thereof, so as to ensure that the optical lens is at the center of the elastic inner ring frame 316. Until the optical lens contacts the limiting thin plate 325, at this time, the stretchable air bag 324 and the limiting thin plate 325 cooperate to 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 transverse push rod 305 and the longitudinal push rod 311 are started according to the laser measuring data, so as to adjust the positions of the upper and lower optical lenses, until the centering is completed.

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

7. A method for centering an aspherical optical lens based on laser detection, using the centering device for aspherical optical lens based on laser detection according to claim 6. The installation base is provided with a mounting slot, and the top of the installation base is provided with a driving motor. The output shaft of the driving motor is connected to an installation plate through a coupling, and the inner wall of the installation plate is provided with three telescopic spring rods. The installation base is provided with a fixed port, and the inner wall of the fixed port is provided with a bidirectional motor. The two output shafts of the bidirectional motor are connected to linkage wheels through couplings, and the installation base is provided with a through circular hole. The two cleaning soft rollers are arranged on the inner wall of the circular hole, and the ends of the two cleaning soft rollers are fixedly connected to transmission wheels. The transmission wheels and the linkage wheels on the same horizontal plane are provided with the same transmission belt. The steps are as follows: Step one: arrange the optical lens on the installation plate, and start the lens cleaning module to clean the centering area of the optical lens; Step two: after cleaning, the picking-up module runs to fix the optical lens by the fixed suction cup, and arranges the optical lens in the two centering bases to complete the picking-up; Step three: during centering, the horizontal centering module runs to adjust the posture of the optical lens to make it in a horizontal state, and then the laser measuring instrument runs to adjust the positions of the upper and lower optical lenses according to the laser measuring data until the centering is completed.
