Abstract

The present invention relates to an optical element processing system and method, in order to solve the technical problems of low polishing efficiency and many human factors of the classical method among the two processing and manufacturing methods for large-diameter optical elements, and complicated control and high cost of high-precision CCOS equipment , provide a large-caliber optical glass grinding and polishing system and method, the system includes a polishing end effector, a turntable, an industrial robot, a control unit and a detection unit, the polishing end effector includes a rotary drive unit, a linear displacement drive, a first fixed seat, the second fixed seat and the grinding head; the grinding head of the polishing end effector realizes rotation and axial movement under the drive of the rotary drive unit and the linear displacement driver, the industrial robot drives the polishing end effector to move, and the turntable is located in the grinding head Directly below, the detection unit is used to detect the surface shape of the workpiece to be processed, and the control unit controls the relevant equipment to process according to the collected data.

Description

technical field [0001] The invention relates to an optical element processing system and method, in particular to a large-diameter optical glass grinding and polishing system and method. Background technique [0002] Large-aperture optical components are an important part of many large-scale optical systems, and their effective aperture and surface accuracy fundamentally determine the performance of the optical system. At present, there are generally two methods of processing and manufacturing in this field: one is to adopt the classical method of polishing, and the manual grinding is repeated for many times. This requires professionals to have rich processing experience, and this method has disadvantages such as low efficiency, many human factors, long processing cycle and high labor intensity; the second is CCOS (Computer Controlled Optical Surface Shaping) equipment processing, this method has good The comprehensive benefits of processing, high equipment precision, and g...
