Description

안경 렌즈 제조 시스템 및 방법Glasses lens manufacturing system and method
본 발명은 안경 렌즈 제조 시스템 및 방법에 관한 것으로, 보다 상세하게는 개개인의 광학적 특성을 반영한 맞춤형 안경 렌즈를 제조할 수 있는 안경 렌즈 제조 시스템 및 방법에 관한 것이다.The present invention relates to a spectacle lens manufacturing system and method, and more particularly to a spectacle lens manufacturing system and method capable of manufacturing a custom spectacle lens reflecting the individual optical characteristics.
일반적으로, 프린터는 프린트 대상물에 문자, 도안 등을 인쇄하는 장치를 의미하며, 컴퓨터에 연결하여 지면에 인쇄하는 프린터 장치 등은 업무용, 가정용 등으로 널리 사용되고 있다. 종래의 프린터는 종이를 소정의 방향으로 이동하며 미세 잉크를 분사하여 2차원 인쇄를 하는 것인데 반해, 최근에 3차원 형상을 형상화할 수 있는 3D 프린터가 등장하였다.In general, a printer means a device for printing a character, a pattern, and the like on a print object, and a printer device that is connected to a computer and printed on the ground is widely used for business, home, and the like. Conventional printers move two sheets of paper in a predetermined direction and spray fine ink to perform two-dimensional printing, whereas a 3D printer capable of shaping three-dimensional shapes has recently emerged.
3D 프린터는 플레이트에 연속적으로 물질을 분사하면서 적층을 하여 3차원 물체를 만들 수 있다. 물체의 맨 아래쪽부터 미세한 두께로 쌓아 올리는 적층 방식은 표현의 한계에서 자유로운 장점이 있다. 3D printers can stack three-dimensional objects by continuously spraying materials onto the plate. The stacking method of stacking up to a small thickness from the bottom of an object has the advantage of being free from limitation of expression.
현재, 3D 프린터 기술을 산업체에서 많이 사용하고 있다. 예를 들어, 완성된 제품을 보기 전에 3D 캐드 소프트웨어로 디자인한 제품을 완성품과 거의 흡사하게 만들어 볼 수 있다. 원료 배합을 통해 다양한 질감을 나타낼 수 있어 견본 제품의 완성도가 높다. 3D 프린터를 이용하는 산업분야는 가전, 우주항공, 자동차, 완구 분야 등은 물론이고, 의료분야까지 매우 다양하다.Currently, 3D printer technology is widely used in industry. For example, before looking at a finished product, a product designed with 3D CAD software can look almost like a finished product. A variety of textures can be achieved through the blending of raw materials, resulting in a high degree of completeness of the sample product. Industrial fields using 3D printers range from home appliances, aerospace, automobiles, toys, and medical fields.
또한, 근시, 원시, 난시 또는 2가지 이상이 복합된 복합시를 갖는 안경 착용 인구는 꾸준히 증가하고 있으며, 복합시의 경우에는 누진다초점렌즈를 사용하는데 렌즈 가격이 고가이고, 스포츠, 레저 활동의 증가로 맞춤형 렌즈의 수요가 증가하고 있다.In addition, the population of eyeglasses with myopia, hyperopia, astigmatism, or a combination of two or more of them is increasing steadily. In the case of compound vision, the number of eyeglasses decreases. Increasing demand for custom lenses is increasing.
이에, 소비자 개개인의 광학적 특성을 반영한 맞춤형 안경 렌즈의 생산을 위해, 3D 프린터 기술을 안경 렌즈의 제조에 도입하는 것을 고려할 수 있으나, 3D 프린터로 안경 렌즈를 제작할 경우, 안경 렌즈의 형상만을 얻을 수 있을 뿐, 각 개인에게 맞는 디옵터를 가진 안경 렌즈의 제작에는 어려움이 있다.Therefore, in order to produce a customized spectacle lens reflecting the optical characteristics of each individual consumer, it may be considered to introduce 3D printer technology into the manufacturing of the spectacle lens, but when manufacturing the spectacle lens with a 3D printer, only the shape of the spectacle lens can be obtained. In addition, there is a difficulty in manufacturing a spectacle lens having a diopter suitable for each individual.

The spectacle lens made by spraying and stacking the printing material in the printer 110 is in an opaque state, thereby performing a grinding process with the grinding particles to improve the opaque state to a transparent state. Hereinafter, each component constituting the spectacle lens manufacturing system will be described in detail.

And, Figure 4 is a side view of the printer and the conveyor in the spectacle lens manufacturing system according to an embodiment of the present invention.
도 1 내지 도 4를 참조하면, 프린터(110)는 인쇄용 물질을 수용하고, 헤드 노즐을 통해 상기 인쇄용 물질을 분사하는 헤드부(112), 상기 헤드부(112)를 이동시키는 갠트리부(114), 및 상기 인쇄용 물질이 적층되어 상기 안경 렌즈가 생성되는 스테이지부(116)를 포함할 수 있다.1 to 4, the printer 110 accommodates a printing material, a head portion 112 for injecting the printing material through a head nozzle, and a gantry portion 114 for moving the head portion 112. And a stage unit 116 in which the printing material is stacked to generate the spectacle lens.
헤드부(112)는 헤드 노즐(미도시)을 통해 안경 렌즈의 원료가 되는 인쇄용 물질을 스테이지부(116)에 분사하면서 샘플 안경 렌즈를 스캔하여 구한 곡률값에 따라 안경 렌즈를 적층 형성한다. 인쇄용 물질로는 아크릴과 같은 플라스틱 수지 등을 사용할 수 있다.The head part 112 stacks the spectacle lenses according to a curvature value obtained by scanning a sample spectacle lens while spraying a printing material, which is a raw material of the spectacle lens, onto the stage part 116 through a head nozzle (not shown). As the printing material, a plastic resin such as acrylic may be used.
여기에서, 샘플 안경 렌즈를 스캔하여 생성되는 3D 모델링 데이터에 따라 헤드부(112)가 인쇄용 물질을 분사하며, 3D 스캐너(미도시)를 사용하여 샘플 안경 렌즈의 전체 형상을 스캐닝(scanning)한다. 스캐닝을 통해 샘플 안경 렌즈의 전체 형상과 곡률값 등에 관한 데이터를 획득한다. 3D 스캐너를 이용한 스캐닝은 제품의 역 설계를 위하여 일반적으로 행해지는 작업이며 점으로서 표현되는 점 데이터를 얻을 수 있다. 프린터(110)에서 안경 렌즈를 만들려면 3D 모델링 데이터(3D Modeling data)가 있어야 하며, 이를 위한 수정작업이 필요하다. 구체적으로, 3D 스캐너에서 획득한 점 데이터를 캐드화하고, 캐드 데이터를 3D 프린팅 기술의 표준 파일 형식인 STL(Stero Lithography) 파일로 변환하고, 3D 조형물을 제작하기 위한 입체 형태의 조형물인가를 검증하는 STL correction 소프트웨어를 이용하여 STL 데이터의 정합성 검사를 하고, STL 포맷 형태의 데이터에 문제가 없다면 데이터를 한층한층 슬라이스해 프린터 헤드를 움직이기 위한 도구경로 데이터인 G code(경로데이터)로 변환한다.Here, the head unit 112 sprays the printing material according to the 3D modeling data generated by scanning the sample spectacle lens, and scans the overall shape of the sample spectacle lens using a 3D scanner (not shown). Through scanning, data about the overall shape and curvature of the sample spectacle lens are acquired. Scanning with a 3D scanner is a common task for the reverse design of a product and it is possible to obtain point data expressed as points. In order to make the spectacle lens in the printer 110, 3D modeling data must be present, and a modification for this is required. Specifically, it is possible to calibrate the point data obtained from the 3D scanner, convert the CAD data into a STL (Stero Lithography) file, a standard file format of 3D printing technology, and verify whether it is a three-dimensional sculpture to produce a 3D sculpture. The STL correction software checks the consistency of STL data. If there is no problem with the STL format data, the data is further sliced and converted into G code (path data), which is tool path data for moving the print head.
이때, 헤드부(112)에 3D 스캐너를 장착함으로써, 스캐닝 및 프린팅을 일괄적으로 수행할 수 있다. 예를 들어, 헤드부(112)에 3개의 센서를 달고, 스테이지부(116)가 회전 가능하도록 설계하여 샘플 안경 렌즈를 상기 스테이지부(116)에 놓고 회전시키면서 스캔하여 점 데이터를 획득할 수도 있다. At this time, by mounting the 3D scanner in the head portion 112, scanning and printing can be performed collectively. For example, three sensors may be attached to the head part 112, and the stage part 116 may be designed to be rotatable, and the sample spectacle lens may be placed on the stage part 116 and rotated to scan and acquire point data. .
갠트리부(114)는 헤드부(112)를 이동시키며, 갠트리부(114)가 헤드부(112)를 상하, 좌우 등으로 이동시킬 수 있어 3D 모델링 데이터에 따른 안경 렌즈가 적층 형성될 수 있다. 이러한 갠트리부(114)는 구동력을 제공하는 갠트리 모터(1141), 헤드부(112)가 연결되어 상기 헤드부(112)를 수평 평면 상에서 이동시키는 수평축(1142), 상기 헤드부(112)를 수직 평면 상에서 이동시키는 수직축(1143), 상기 갠트리 모터(1141), 수평축(1142), 수직축(1143) 등을 고정 및/또는 연결하는 제1 연결부재(1144), 제2 연결부재(1145) 등을 포함할 수 있다.The gantry part 114 moves the head part 112, and the gantry part 114 may move the head part 112 up, down, left, and the like, so that the spectacle lens according to the 3D modeling data may be stacked. The gantry 114 is a horizontal axis 1142 for moving the head 112 on the horizontal plane is connected to the gantry motor 1141, the head 112 to provide a driving force, the head 112 is vertical The first connecting member 1144, the second connecting member 1145, etc. for fixing and / or connecting the vertical axis 1143, the gantry motor 1141, the horizontal axis 1142, the vertical axis 1143, etc. to move on a plane. It may include.
스테이지부(116)는 헤드부(112)에서 분사된 인쇄용 물질이 적층되는 곳으로, 안경 렌즈가 생성되는 위치가 된다. 스테이지부(116)에 생성된 안경 렌즈는 불투명 상태가 된다. 헤드부(112)에서 분사되는 인쇄용 물질이 아크릴 등의 플라스틱 소재이므로, 안경 렌즈의 투명도를 개선하기 위해 연삭 가공 등의 후처리 공정이 필요하다. 스테이지부(116)는 안경 렌즈의 후처리를 위해, 상기 안경 렌즈를 컨베이어(120)로 이동시킨다. 구체적으로, 스테이지부(116)는 분사된 인쇄용 물질이 적층되는 플레이트(1161), 구동력을 제공하는 스테이지 모터(1162), 구동력을 전달하는 전달축(1163), 각 구성요소들을 고정 및/또는 연결하는 제3 연결부재(1164) 등을 포함할 수 있다.The stage unit 116 is a place where the printing material jetted from the head unit 112 is stacked and becomes a position where the spectacle lens is generated. The spectacle lens generated in the stage portion 116 is in an opaque state. Since the printing material sprayed from the head portion 112 is a plastic material such as acrylic, a post-treatment process such as a grinding process is required to improve the transparency of the spectacle lens. The stage unit 116 moves the spectacle lens to the conveyor 120 for post-processing the spectacle lens. In detail, the stage unit 116 may include a plate 1161 on which the sprayed printing material is stacked, a stage motor 1162 providing a driving force, a transmission shaft 1163 transmitting a driving force, and fixing and / or connecting the components. The third connection member 1164 may be included.
컨베이어(120)는 안경 렌즈의 후처리를 위해 상기 안경 렌즈를 이동시키는 역할을 한다. 도 1 및 도 2에 컨베이어(120)가 타원형으로 배치된 것으로 도시되어 있으나, 이에만 제한되지 않고 직선형이나 원형 등 다른 형태로 배치될 수도 있음은 당업자에게 자명하다 할 것이다.The conveyor 120 serves to move the spectacle lens for post-processing the spectacle lens. 1 and 2, the conveyor 120 is shown as being disposed in an elliptical shape, but is not limited thereto, and it will be apparent to those skilled in the art that the conveyor 120 may be arranged in other forms such as straight or circular.

Here, the injection pressure of the post-processor 130 is preferably set to about 2.5 ~ 3kg / ㎠.
컨베이어(120)에 의해 불투명 상태의 안경 렌즈(L)가 이동 시, 후처리기(130)가 컨베이어(120)의 상부에서 연삭 입자 등을 분사하여 안경 렌즈(L)를 후처리함으로써, 불투명 상태의 안경 렌즈(L)가 투명 상태의 안경 렌즈(L)로 투명도가 개선된다. 예를 들어, 도 5에 도시한 바와 같이, 연삭 입자를 분사하여 안경 렌즈의 투명도를 개선하고(①/②), 물 및 에어를 분사하여 연삭 입자에 의해 연삭 가공된 안경 렌즈를 세척하고 건조한다(③/④).When the spectacle lens L in the opaque state is moved by the conveyor 120, the post-processor 130 post-processes the spectacle lens L by spraying grinding particles or the like on the upper portion of the conveyor 120, thereby Transparency is improved to the spectacle lens L in the transparent state.
