Description

Technical Field

[0001] The invention relates to the field of optical processing technology, and in particular to a small grinding head processing device, method and storage medium. Background Art

[0002] In the field of optical processing, small grinding head processing has become an important processing method due to its high precision and flexibility. This processing method uses a computer to accurately control a grinding disc with a smaller diameter to perform fine grinding and polishing operations on the surface of optical components, thereby achieving precise control of the amount of material removal and improving the surface quality of optical components.

[0003] During the small grinding head processing, the grinding fluid is usually applied to the entire upper surface of the processed component. The main function of the grinding fluid is to cooperate with the grinding head to perform grinding operations, ensure the smooth progress of the processing process and the steady improvement of the quality of the processed components.

[0004] However, when processing large-diameter optical components, since the entire processing process takes several hours, the grinding fluid on the surface of the optical components far away from the starting position of processing often dries out or even oxidizes due to long-term exposure to the air. Once the grinding fluid dries out or even oxidizes, its physical and chemical properties will change, which will not only increase the grinding resistance, but also may cause damage to the surface of the optical component, seriously affecting the processing effect. In order to deal with this problem, traditional methods often require operators to continuously spray water or manually apply grinding fluid to keep the grinding area moist. However, this manual water replenishment method is not only labor-intensive, but also difficult to ensure precise control of the amount of water replenishment. For large-diameter optical components, it is difficult for a person's arm span to cover the entire surface of the optical component, and auxiliary tools are needed for water replenishment, which increases the uncertainty and safety hazards in the processing process, thereby affecting the stability and efficiency of the processing, and also makes it difficult to achieve complete automation of the processing of small grinding heads.

[0005] In the existing small grinding head processing method, the problems with applying grinding fluid cannot be ignored. First, it is difficult to ensure uniformity and continuity when applying grinding fluid manually, especially when processing large-diameter optical components. The uneven distribution of grinding fluid may lead to increased local wear. Secondly, the grinding fluid is prone to dry out after being exposed to the air for a long time, losing its lubrication and cooling effects, increasing grinding resistance and potential damage to the surface of the component. Furthermore, oxidation problems of the grinding fluid also occur from time to time, affecting its performance and may introduce contaminants. These problems not only reduce processing efficiency, but also increase uncertainty and risks in the processing process, posing a threat to the final quality of optical components. Therefore, optimizing the grinding fluid application method and realizing a smarter and more stable supply system are key issues that need to be urgently solved in the current small grinding head processing technology.

[0006] The Chinese patent document with application number CN202322138645.9 discloses a small grinding head optical processing water replenishment device, which improves the uniformity of water spraying through ultrasonic atomizers, so that the grinding liquid remains moist during the processing. However, it cannot improve the oxidation problem caused by the grinding liquid being exposed to the air for a long time, and the application of the grinding liquid still depends on the operator's experience.

[0007] The Chinese patent document with application number CN202110468153.9 discloses a processing method and device for central liquid supply chemical mechanical polishing of semiconductor materials, which adopts a central liquid supply scheme.
