Embodiment Construction

[0028] As shown in the figure, the intelligent flexible polishing method for aspheric optical elements can be implemented as follows:

[0029] (1) The robot scans the workpiece through the sensor to collect the feature information of the workpiece;

[0030] (2) The robot control system determines the theoretical polishing trajectory according to the data collected in step (1);

[0031] (3) The polishing mechanism drives the polishing airbag to move on the surface of the workpiece along the theoretical polishing track described in step (2). By controlling the corresponding process parameters on the surface of the workpiece, the amount of material removal at each point on the surface of the optical element is accurately controlled;

[0032] (4) The robot control system controls the surface error of the workpiece through multiple iterations, and finally completes the polishing operation.

[0033] According to the requirements of the surface shape and roughness of the polished curved surfac...

Abstract

The invention belongs to the technical field of optical machining and particularly relates to an intelligent flexible polishing method for a non-spherical optical element and an intelligent flexible polishing device adopted for the intelligent flexible polishing method. The intelligent flexible polishing method includes the steps that (1) a robot scans a workpiece through a sensor to collect characteristic information of the workpiece; (2) a robot control system determines a polishing theoretical track; (3) a polishing mechanism drives a polishing airbag to move on the surface of the workpiecealong the polishing theoretical track, and the material removal quantities of various points on the surface of the optical element are accurately controlled; and (4) the robot control system carriesout iterative operation repeatedly so as to control the surface shape error of the workpiece. The intelligent flexible polishing device comprises the robot (1), a rotating joint (2), a workbench (10),an air pressure adjusting device (12), the robot control system (13), the polishing mechanism (7) and a computer (14). A machine area is stable, surface shape adaptability is good, the operating conditions of a polishing system can be monitored in real time, and ultraprecise polishing of large-size high-curvature non-spherical surfaces is achieved.

Description

Technical field [0001] The invention belongs to the technical field of optical processing, and in particular relates to an intelligent flexible polishing method for aspheric optical elements and an intelligent flexible polishing device adopted by the same. Background technique [0002] In optical systems, aspherical surfaces are more and more widely used, which can improve imaging quality, simplify instrument structure, reduce costs, and improve stability. However, due to the non-uniform curvature of the aspheric surface, its precision machining and processing efficiency have always restricted the wide development and application of aspheric surfaces. Therefore, how to process aspheric elements with high precision and efficiency has become a key issue to be solved urgently. [0003] The principle and characteristic of computer-controlled optical surface forming technology is to use a polishing mold whose size is much smaller than that of the processed part. According to the quanti...
