Description

TECHNICAL FIELD

[0001] The utility model relates to the field of optical manufacturing, especially relates to a clamping assembly for edging spectacle lenses. BACKGROUND

[0002] In the field of optical manufacturing, edging spectacle lenses is an important step to process lenses to meet specific frame shapes and sizes. An efficient clamping assembly plays a crucial role. Its main use scenarios include fixing lenses to ensure the accuracy of shape processing, adapting to the needs of various materials such as glass and resin, and supporting the processing of lenses from circular to irregular shapes. The clamping assembly can also meet the micron-level processing accuracy requirements of high-end lenses and avoid affecting optical performance due to errors.

[0003] A clamping assembly for edging mainly consists of clamping components, adjustment mechanisms, positioning mechanisms, and edging structure interfaces, aiming to provide stable and efficient support for lens edging. The clamping component fixes the lens through clamping jaws, vacuum suction, or flexible materials to prevent displacement or vibration during processing. The adjustment mechanism adjusts the position and angle through sliding rails or screws to adapt to lenses of different shapes and sizes. The positioning mechanism uses positioning pins or laser systems to ensure accurate alignment of the lens in the edging equipment. The edging structure interface is connected through rotation or guide rails to ensure that the clamping assembly moves synchronously with the edging equipment, achieving smooth cutting or polishing.

[0004] However, traditional devices use mechanical rigid fixation for edging spectacle lenses, which lacks precise control of force and can easily cause edge breakage or surface damage due to excessive pressure, especially for lenses with brittle materials. The safety is insufficient. Secondly, the debris generated during polishing is usually handled by simple dust collection or gravity falling, which can lead to incomplete cleaning of the processing area, and debris residues may affect polishing accuracy. At the same time, wastewater treatment is mostly direct discharge, which not only wastes water resources but also affects the environment.

During the trimming process, the motor 10 drives the lower fixing disc 11 to rotate, the rough edge lens 8 rotates and the electric push rod 6 can always act on the upper fixing disc 501 to fix the rough edge lens 8 due to the action of the bearing 503, and the polishing head 705 of the three polishing mechanisms 7 ensures proper contact with the lens edge by relying on the spring 703 structure, and accurate trimming is completed. At the same time, the cleaning mechanism 4 is started, the water pump 404 delivers water to the annular water pipe 401, and a high-pressure water flow is sprayed to the middle of the processing ring 1 through multiple high-pressure nozzles 402, and the debris and cutting fluid generated during trimming are washed away. Because the inside center to the side of the processing ring 1 has a certain curvature, the debris and waste liquid can flow into the collecting hopper 902 through the multiple through holes 901 on the processing ring 1, after separation by the filter cartridge 903, the solid debris is left in the filter cartridge 903, and the filtered water is returned to the water pump 404 through the water inlet pipe 405, realizing water resource recycling. The whole set of device is compact in structure, clean and efficient, and can ensure trimming quality and environmental protection performance.
