Aspheric lens centering device and aspheric lens centering method

The invention provides an aspheric lens centering device comprising a horizontal position adjusting mechanism. The horizontal position adjusting mechanism comprises a pushing block and a slide rail, and the pushing block is slidably connected with the slide rail by a connecting rod. A processing module is used to extract a minimum axes deviation angle from received axes deviation angles, and a displacement value is calculated according to the minimum axes deviation angle. A driving motor is used to drive the connecting rod to move in the slide rail, and the displacement of the connecting rod is a displacement value, and then the pushing block is used to push a to-be-processed lens, and then the optical axis of the to-be-processed lens is superposed with a reference axis. The invention also provides an aspheric lens centering method. The processing module is used to calculate the displacement value according to the received minimum axes deviation angle, and therefore the driving motor is used to drive a pulley
