       The present invention is a rotary type of glass lens that automates the supply and discharge, processing (polishing) and measurement of materials to process spherical glass lenses used in precision optical products in image recording fields such as digital cameras, mobile phones and CCD TVs. More specifically, it relates to the automatic polishing device. More specifically, it is possible to supply the glass lens material and discharge the workpiece, grinding, finishing, polishing, washing and curvature measurement, polishing, polishing, and polishing. Eight lens holders are mounted on the arm of the rotary rotary spindle, XY axis transferr and rotary chucking part are installed on one side of the lower part, and the tools for grinding, finishing, and polishing are installed in the clockwise direction. The polishing and ultra-sharp finish tools were installed sequentially so that the glass lens can be spherically processed as the arm of the spindle rotates.

        In general, the processing of the lens consists of a device for conveying the lens material, a device for fixing the lens and a device for polishing the lens to automatically and manually supply and fix the spherical lenses (concave lens, convex lens) curved in a hemispherical shape. Through the polishing apparatus of the lens, the surface of the lens is polished and processed into a predetermined shape and molded.

       In the conventional glass lens forming apparatus, three equipments, a grinding apparatus, a finishing apparatus, and a polishing apparatus for processing a lens material, are respectively installed and polished and processed while measuring curvature with a separate measuring instrument.

Was molded and processed, and the lenses processed in each of the above processes were measured manually in a separate measuring machine and transferred to the next process for processing.

       In the conventional processing apparatus and method described above, three equipments are installed, so the occupancy of the work space is high, and thus the work space can not be effectively used, and more than five skilled workers are required, resulting in an increase in facility cost (112 million won) and labor costs. As the automatic and manual process is repeated in the process of processing and measuring, there are problems such as delay in production time and productivity, as well as processing error, which lowers the reliability of product quality.

       In addition, the conventional device can process more than Ø5.0 of the processing material, production conditions are R: 5.0-45.0, T: 0.5 or more, and the surface roughness is PV: 0.3nm, Rms: 0.03nm or more There were problems such as narrow selection of materials and low precision and roughness.

Therefore, the present invention was created for the purpose of solving the conventional problems as described above, equipped with eight lens holders on the rotary rotary arm on the upper side, and the supply and discharge of the lens material on the lower one side, grinding clockwise, It is a single device that installs finishing, polishing, measuring, measuring, polishing, polishing, and polishing processes in order to automatically produce lens materials as spherical surfaces, improving utilization of work space, shortening production time and processing of products. It is possible to improve the product quality by lowering the error and to provide the polishing device that can reduce labor cost and maintenance cost because it is automatically produced by unmanned work or single work.

In addition, another object of the present invention is to reduce the equipment cost (approximately 85 million won) by the equipment of a single device, and to allow processing of the processing material specifications of Ø2.0 or more, and the production conditions of the lens is R: 1.5-25.0, T: It is 0.3 or more and the surface roughness is PV: 0.2nm, Rms: 0.02nm or more to expand the selection of lens materials to be processed and improve the precision and surface roughness of the lens.
