Description

TECHNICAL FIELD

[0001] The utility model relates to the field of optical lens grinder, especially relates to a grinder for optical lens production and processing. BACKGROUND

[0002] The optical lens grinder is a device for processing optical lenses and plays a key role in the field of optical lens manufacturing. The working principle of the optical lens grinder is that the abrasive in the grinding liquid is dispersed and uniformly distributed on the surface of the grinding disc by the rotation of the grinding disc, forming a thin film of grinding liquid. The grinding liquid nozzle continuously sprays the grinding liquid to wash the thin film of grinding liquid, so that it is constantly updated, thereby achieving better grinding effect. At the same time, the rotation of the rotating shaft drives the grinding disc to rotate, so that the grinding liquid forms a vortex on the surface of the grinding disc, which is beneficial to the discharge of grinding waste.

[0003] In the production and processing process of optical lenses, the grinder, as one of the key equipment, plays a crucial role. However, in actual application, due to the different diameters required by the lenses, different positioning methods and adjustment strategies are needed for lenses of different diameters during the grinding process. However, the existing grinder often adopts a relatively single positioning method in lens positioning, which is difficult to adapt to the needs of lenses of different diameters. This leads to problems such as inaccurate positioning, deviation or rotation of the lens during processing, thereby affecting the processing precision and quality of the lens.

[0004] The adjustment accuracy of the grinder is limited, which is difficult to meet the needs of high-precision lens processing. For lenses with smaller diameters or higher precision requirements, the grinder may have a large error in positioning and adjustment, resulting in the shape, size and optical performance of the processed lens not meeting the design requirements. Due to the limitations of the design principle and manufacturing process of the grinder, its flexibility and adaptability in lens positioning are relatively poor. When faced with lenses of different diameters, different materials and different shapes, the grinder may not be able to effectively adjust and adapt, thereby limiting its application range in the field of lens processing.
