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.

일반적으로 렌즈의 가공은 렌즈소재를 이송하는 장치와 렌즈를 고정시키는 장치 및 렌즈를 연마하는 장치로 구성되어 반구형으로 굴곡 처리된 구면렌즈(오목렌즈,볼록렌즈)를 자동 또는 수동으로 공급 및 고정시키고 상기 렌즈의 연마장치를 통하여 렌즈의 면을 일정한 형상으로 연마,가공하여 성형시키고 있는 것이다.        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.

종래의 글라스 렌즈 성형장치는 렌즈소재를 가공하는 연삭장치,정삭장치 및 연마장치의 3대의 장비를 각각 설치하고 별도의 계측기로 곡률을 측정하면서 연마, 가공하였다.       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.

상기 장치의 가공방법은 3대의 장비(연삭,정삭,연마)에서 가공소재를 상측에서 고정시키고 하측에서 자화전 및 요동운동으로 연삭,정삭,초정삭,연마의 4개공정을 자동 또는 수동으로 렌즈를 성형 및 가공하고 상기 각 공정에서 가공된 렌즈를 별도의 측정기에서 수동으로 계측하고 다음공정으로 이송하여 가공하였다.       The processing method of the device is to fix the processing material on three machines (grinding, finishing, polishing) from the upper side and the four processes of grinding, finishing, ultra-finishing and polishing by magnetizing and swinging motion on the lower side automatically or manually. 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.

상기한 종래의 가공장치 및 방법은 3대의 장비를 설치하므로 작업공간의 점유률이 높아 작업공간을 효과적으로 활용할 수 없고 5명 이상의 숙련된 작업인원이 소요되어 설비비용(1억2100만원)과 인건비가 상승되며 가공과 측정의 공정에서 자동과 수동이 반복되면서 제작시간의 지연과 생산성이 저하될 뿐만 아니라 가공오차가 발생하여 제품품질의 신뢰도가 저하되는 등의 문제점이 있었다.       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.

또한 종래의 장치는 가공소재의 규격이 Ø5.0이상을 가공할 수 있고 생산조건은 R:5.0-45.0,T:0.5이상이며 표면조도는 PV:0.3nm,Rms:0.03nm 이상으로 가공할 렌즈소재의 선택폭이 좁고 정밀도 및 조도가 낮은 등의 문제점이 있었다.       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.

따라서 본 발명은 상기와 같은 종래의 문제점을 해결하기 위한 목적으로 창출된 것으로 상부에 회전 로터리식 아암에 8개의 렌즈홀더를 장착시키고 하부 일측에 렌즈소재의 공급과 배출부를 설치하며 시계방향으로 연삭,정삭,정마가공부,계측부,초정마,연마,초연마가공부를 순차적으로 설치한 단일장치로 렌즈소재를 구면으로 자동 생산할 수 있게 하여 작업공간의 활용도를 향상시키고 제작시간을 단축시 키며 제품의 가공오차를 저하시켜 제품품질을 향상시킬 수 있으며 무인작업 또는 1인작업으로 자동생산하므로 인건비와 유지보수비용을 절감시킬 수 있게 한 연마장치를 제공할 수 있게 하였다.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.

또한 본 발명의 다른 목적은 단일장치의 장비로 설비비용(약8500만원)를 절감시키고 가공소재의 규격이 Ø2.0이상을 가공할 수 있게 하고 렌즈의 생산조건은 R:1.5-25.0,T:0.3이상이며 표면조도는 PV:0.2nm,Rms:0.02nm 이상으로 가공할 렌즈소재의 선택폭이 확장시키고 렌즈의 정밀도 및 표면조도를 향상시킬 수 있게 한 것이다. 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.
