Control system and method of co-fusion robot for optical mirror surface machining

Abstract

The invention discloses a control system and method of a co-fusion robot for optical mirror surface machining. The intelligent control system controls a machining platform driving device, a cutting tool rack driving device, a flexible hydraulic supporting device and a rotating platform control device through a multi-axis motion controller and a machining platform motion controller respectively tomachine an optical mirror surface; a high-precision three-coordinate detector can feed information back to the intelligent control system in real time; a visual detection device collects spatial position information of a machined object and spatial position information of a mechanical arm in real time and feeds the information back to the intelligent control system. The intelligent control systemplans a machining route and conducts programming of a machining algorithm according to the feedback information in the machining process, the co-fusion robot has coordination performance and learnability at the same time in the process of machining the optical mirror surface, and therefore the requirement of optical mirror surface machining for high precision is met.

Description

technical field [0001] The invention relates to an optical mirror processing equipment, in particular to a control system and method for a fusion robot for optical mirror processing, and belongs to the technical field of precision optical component processing equipment. Background technique [0002] With the continuous development of surface processing technology, optical free-form surface parts as the core components have been widely used in aerospace, national defense and other fields, such as turbine blades, ship propellers, etc., many of which are also used in civilian fields, such as Camera Cameras, projectors, large telescopes, etc. And the modern optical free-form surface is rapidly developing in the direction of large diameter, high precision, and large angle, so the demand and precision requirements for the optical free-form surface are also increasing day by day, and the processing of each link of the optical mirror surface will directly affect the processing of th...

Problems solved by technology

[0003] The existing optical mirror processing equipment mainly includes components such as a rotating support table, a processing arm, a static platform, a moving platform, and a processing tool holder. The rotating supporting processing platform is fixed on the static platform to support the mirror surface to be processed. The platform is installed at the lower end of the processing arm and moves with the moving platform under the drive of the processing arm; the control system of the whole equipment controls each module for processing according to the processing route planned in advance, and the control systems of each module are independent of each other, so Lack of coordination makes it impossible to judge in advance when encountering external interference or unknown factors, or when a control system has a problem, it is difficult for other control modules to detect it in time, which has a certain lag and passivity, which will cause optical mirror processing. Accuracy, it is difficult to meet the needs of high-precision mirror processing
