Problems solved by technology

[0004] The disadvantage of the traditional judgment method is that the method of recording the working time of the polishing mold is used. Due to factors such as the polishing speed, the speed of polishing liquid addition, and the temperature, the same working time will be caused, and the degree of wear of the polishing mold will be inconsistent.
Repairing the polishing mold too early will cause waste and destroy the polishing process; repairing the polishing mold too late will result in a decrease in polishing efficiency and an increase in polishing costs
The method of stopping the measurement will cause the pollution of the polishing mold and the reduction of polishing efficiency.

Abstract

The invention discloses a device and a method for detecting the disc repairing period of a polishing die. The device comprises an optical detecting component, a processor and a levelness measuring component. The optical detecting component uses structured light to detect the surface topography of the polishing die; and the processor calculates and processes to obtain the depth and width information of a groove in the surface of the polishing die through the received probe light comprising the surface topography information of the polishing die, so that the repairing period of the polishing dieis determined, and the maintaining time node of the polishing die is monitored. The device is simple in structure, precise in measurement and rapid in response, realizes in-situ detection of the discrepairing period of the polishing die, ensures the grinding activeness of the surface of the polishing die and improves the processing efficiency and the processing quality.

Description

technical field [0001] The invention relates to an auxiliary device for optical element ring polishing, in particular to the repairing cycle and working life of a polishing mold, and belongs to the technical field of optical element processing. Background technique [0002] The polishing process of optical components is usually to bond or cast a layer of polishing mold on the polishing disc driven by a motor, place one or more components to be processed on the polishing mold, and the components rotate at a specific angular speed. At the same time, the polishing liquid is added to the polishing mold, and the surface shape of the polishing mold is transferred and copied to the component through the mechanochemical action of the optical components and polishing powder particles on the polishing mold, so as to obtain a globally smooth planar component and complete the polishing of the component. [0003] The commonly used polishing mold material for polishing is generally asphal...
