본 고안은 광학소자의 정밀가압성형장치에 관한 것으로서, 더욱 상세하게는 성형장치로서 캠코더 및 픽업 등에 사용되는 비구면 유리렌즈를 성형시 피성형광학 유리소재를 연속적으로 공급할 수 있도록 한 것이다.The present invention relates to a precision pressure forming apparatus for an optical element, and more particularly, to provide an optical glass material continuously when molding an aspherical glass lens used for a camcorder and a pickup as a molding apparatus.
일반적으로, 렌즈, 프리즘, 미러 및 필터등의 광학소재는 유리소재를 연삭하여 외형을 원하는 형태로 한 다음 연마에 의해 광학기능면, 즉 빛을 투과 또는 반사하는 광학면을 얻게 된다.In general, optical materials such as lenses, prisms, mirrors and filters are obtained by grinding a glass material into a desired shape and then polishing to obtain an optical functional surface, that is, an optical surface that transmits or reflects light.
최근, 특수한 금형재료를 이용하여 그 표면을 광학경면으로 가공한 후 금형으로 광학유리소재를 정밀가압성형해서 연삭 및 연마를 하지 않고 광학경면을 갖는 렌즈를 제조할 수 있는 데, 금형재료로서는 예컨데, 유리상카본, Sic 또는 Si3N4, Sic와 탄소와의 혼합물 및 유리등을 사용하며, 렌즈성형시 융착을 방지하고 이형을 좋게하기 위해서는 Pt, TiN등의 물질로 박막을 입히게 된다.Recently, a special mold material is used to process the surface into an optical mirror surface, and then the optical glass material is precisely press-molded with a mold to manufacture a lens having an optical mirror surface without grinding and polishing. Glassy carbon, Sic or Si 3 N 4 , a mixture of Sic and carbon and glass are used. To prevent fusion and improve mold release during the lens forming, thin films are coated with materials such as Pt and TiN.
이같은 방법으로 렌즈를 제조하게 되면, 종래의 연삭 및 연마공정이 불필요하므로 인해 제조경비가 크게 절감되고, 연삭 및 연마공정에 의해 비구면렌즈를 제조하기 위해서는 20여 공정을 거치게 되는 반면, 정밀가압성형에 의해서는 불과 5-6공정만 거치면 되며, 한번에 여러개의 렌즈를 성형할 수 있어서 제조경비의 절감효과가 매우 크게 된다.If the lens is manufactured in this manner, the conventional grinding and polishing process is unnecessary, so the manufacturing cost is greatly reduced, and in order to manufacture the aspherical lens by the grinding and polishing process, the process goes through about 20 steps. Only 5-6 steps are required, and several lenses can be molded at one time, thereby greatly reducing the manufacturing cost.
종래의 렌즈성형방법은 금형내에 유리괴를 넣어서 진공배기후 비산화성가스를 채워서 금형과 함께 유리를 승온시켜 가압을 시작하고, 금형과 함께 유리를 냉각시켜 유리가 전이온도 이하로 되기까지 가압하며, 금형의 산화를 방지하기 위해 300℃이하까지 냉각시켜서 취출시키므로 승온, 가압 및 냉각등의 각 공정을 전부같은 챔버내에서 하게 된다.Conventional lens forming method is to put the glass in the mold, and after vacuum evacuation to fill the non-oxidizing gas to heat the glass with the mold to start the press, and to cool the glass with the mold to press the glass until the transition temperature, In order to prevent oxidation of the mold, it is cooled down to 300 ° C or lower, and thus, each process such as heating, pressurization and cooling is performed in the same chamber.
그러나, 이와같은 종래렌즈의 성형시에는 금형내에 유리괴를 넣고 금형과 함께 광학유리소재를 성형가능한 온도범위까지 가열하여 가압한 후, 광학유리의 스트레인을 제거하기 위해 유리의 전이온도 이하로 냉각해야 하고, 금형의 산화를 방지하기 위해 적어도 300℃이하로 냉각한 후 취출하게 되는데 이러한 승온, 가압 및 냉각공정이 하나의 챔버내에서 행해지게 되므로 사이클타임이 매우 길어지게 될 뿐만 아니라, 연속적인 성형이 불가능하며, 성형실의 온도를 승온 및 냉각시키므로 에너지 효율이 저하되는 등의 많은 문제점이 있었다.However, in the molding of such a conventional lens, the glass ingot is placed in the mold, and the optical glass material is heated together with the mold to be pressurized by heating to a moldable temperature range, and then cooled to below the glass transition temperature to remove the strain of the optical glass. In order to prevent oxidation of the mold, cooling is carried out after cooling to at least 300 ° C. or lower. Since the temperature raising, pressurizing, and cooling processes are performed in one chamber, the cycle time becomes very long, and continuous molding is performed. It is impossible, and there are many problems such as lowering the energy efficiency because the temperature of the molding chamber is raised and cooled.
본 고안은 상기한 제반 문제점을 해결하기 위한 것으로서, 본 고안은 성형장치로서 캠코더 및 픽업등에 사용되는 비구면 유리렌즈를 성형시 피성형 광학유리소재를 연속적으로 공급할 수 있도록 하여 생산성을 대폭 향상시킬 수 있는 광학소자의 정밀가압성형장치를 제공하는데 그 목적이 있다.The present invention is to solve the above-mentioned problems, the present invention is to provide a molding apparatus to continuously supply the optical glass material to be molded when aspheric glass lens used in the camcorder and pickup, etc. can greatly improve the productivity It is an object of the present invention to provide an accurate pressure molding apparatus for an optical element.
상기한 목적을 달성하기 위해 본 고안은 예열실에 성형용 유리소재가 안착된 복수개의 홀더가 제1실린더의 축에 적치되어 제1실린더에 의해 홀더가 점진적으로 상승하여 순차적으로 성형실로 공급할 수 있도록 된 광학소자의 정밀가압성형장치이다.In order to achieve the above object, the present invention provides a plurality of holders in which a molding glass material is seated in a preheating chamber so that the holders are gradually raised by the first cylinder so that the holders can be sequentially supplied to the molding chamber by the first cylinder. Precision molding machine for optical devices.
