Include.
성형챔버(110)는, 상하면이 평행하고 상하면의 면적에 비해 높이가 상대적으로 작은 납잡한 기둥(예:직육면체, 원기둥, 타원기둥, 다면체 기둥) 형상으로 구비되며, 내부 청소 등을 위해 상부와 하부를 분리하고, 상부를 개폐할 수 있도록 상부와 하부가 힌지결합될 수 있다.The forming chamber 110 is provided in the shape of a braided column (eg, a rectangular parallelepiped, a cylinder, an elliptical column, a polyhedral column) having a parallel upper and lower surfaces and a relatively small height compared to the area of the upper and lower surfaces. The upper and lower parts may be hinged to separate and open and close the upper part.
성형챔버(110)는, 성형대상물(10)의 성형을 위한 성형공간(111)을 가지며, 성형공간(111)은 앞서 설명한 바와 같이 상하방향으로 서로 마주하며 평행한 상면(111a)과 하면(111b)을 가지면, 상면(111a)과 하면(111b)의 면적에 비해 높이가 상대적으로 작은 납잡한 기둥 형상으로 구비된다.The molding chamber 110 has a molding space 111 for molding the molding object 10, and the molding space 111 faces each other in the vertical direction as described above and is parallel to the upper surface 111a and the lower surface 111b. ), the height is relatively small compared to the area of the upper surface 111a and the lower surface 111b.
성형챔버(110)는, 내부 성형공간(111)의 온도가 균일하게 형성되도록 열전도도가 높은 재질(예: 알루미늄)로 구비된다. The forming chamber 110 is formed of a material having high thermal conductivity (eg, aluminum) so that the temperature of the inner forming space 111 is uniformly formed.
열원유닛(120)은, 성형공간(111)에 구비되는 금형유닛(130)이 성형에 적합한 온도를 갖도록 가열하는 구성으로서, 성형공간(111)을 형성하는 내면에 구비된다.The heat source unit 120 is configured to heat the mold unit 130 provided in the molding space 111 to have a temperature suitable for molding, and is provided on an inner surface forming the molding space 111.
본 실시형태에서, 열원유닛(120)이 금형유닛(130)과 분리되어 구비된 상태에서 금형유닛(130)이 성형에 적합한 온도를 갖도록 가열함으로써, 금형유닛(130)의 소형화가 가능하고, 그 결과로 소형화된 금형유닛(130)을 가열하는데 소요되는 시간(승온 시간)을 단축할 수 있다. 또한 소형화된 금형유닛(130)의 온도를 균일하게 유지하는 것이 용이하므로 성형대상물(10)의 성형품질이 향상된다. In this embodiment, by heating the mold unit 130 to have a temperature suitable for molding while the heat source unit 120 is provided separately from the mold unit 130, it is possible to downsize the mold unit 130, As a result, it is possible to shorten the time required to heat the downsized mold unit 130 (heating time). In addition, since it is easy to uniformly maintain the temperature of the downsized mold unit 130, the molding quality of the molding object 10 is improved.
열원유닛(120)은, 적외선을 방출하는 할로겐 램프로 구비되며, 성형공간(111)의 상면(111a)과 하면(111b) 모두에 구비될 수도 있고, 상면(111a)에만 구비될 수도 있다.The heat source unit 120 is provided with a halogen lamp emitting infrared rays, and may be provided on both the upper surface 111a and the lower surface 111b of the molding space 111, or may be provided only on the upper surface 111a.
금형유닛(130)은, 열원유닛(120)과 분리되어 성형공간(111)에 배치되며, 열원유닛(120)에 의해 전달되는 열에 의해 가열되고, 내부에 배치되는 성형대상물(10)을 성형하는 구성이다.The mold unit 130 is separated from the heat source unit 120 and disposed in the molding space 111, heated by the heat transferred by the heat source unit 120, and molds the molding object 10 disposed therein. Configuration.
금형유닛(130)은, 상부금형(131)과 하부금형(132)으로 구성되고, 성형대상물(10)의 성형을 위해 서로 계합되도록 구비된다.The mold unit 130 is composed of an upper mold 131 and a lower mold 132, and is provided to engage with each other for molding the object 10.
한편, 본 실시형태에서, 하부금형(132)은 성형챔버(110)에 고정되어 구비되고, 상부금형(131)은 대응하는 하부금형(132)과 계합되도록 상면(111a)과 하면(111b)과 직교하는 방향으로 왕복이동하도록 구비된다.On the other hand, in this embodiment, the lower mold 132 is provided while being fixed to the forming chamber 110, and the upper mold 131 has an upper surface 111a and a lower surface 111b so as to engage with the corresponding lower mold 132. It is provided to reciprocate in a direction orthogonal.
도 3과 달리, 상부금형(131)과 하부금형(132)이 서로 반대로 형성되는 것이 배제되지 않는다.Unlike FIG. 3, it is not excluded that the upper mold 131 and the lower mold 132 are formed opposite to each other.
이때, 상부금형(131)과 하부금형(132)은, 서로 마주하는 면에 서로 정합되는 형상의 상부 성형면(131a)과 하부 성형면(132a)을 가지되, 하부 성형면(132a)이 상부 성형면(131a)에 삽입되는 형상으로 구비된다.At this time, the upper mold 131 and the lower mold 132 have an upper molding surface 131a and a lower molding surface 132a having a shape matching each other on a surface facing each other, but the lower molding surface 132a is the upper It is provided in a shape that is inserted into the molding surface (131a).
상부금형(131)과 하부금형(132)은, 탄화규소 재질로 구비된다. The upper mold 131 and the lower mold 132 are made of silicon carbide.
이에 의하면 커버글라스 성형시 성형대상물과 금형의 점착을 방지할 수 있고, 금형의 발열온도의 급속 상승에도 효과적이다. 또한 금형의 온도를 커버글라스의 성형에 적합한 550℃ 또는 그 이상으로 상승시켜도 열산화물이나 분진의 발생이 방지된다. Accordingly, adhesion between the object and the mold can be prevented when forming the cover glass, and it is also effective to rapidly increase the heating temperature of the mold. In addition, even if the temperature of the mold is raised to 550℃ or higher suitable for forming a cover glass, the generation of thermal oxide or dust is prevented.
이에 비해, 커버글라스(유리)를 성형대상물로 하고 금형의 온도를 550℃ 이상로 하며, 금형재질로 Al과 Pt를 코팅한 경우, 점착성이 높고 열산화물 및 변색이 발생되며, 금형재질을 칸탈(KANTHAL, 철을 주체로 하고 크로뮴, 알루미늄 등이 합해진 합금)을 적용한 경우에도 점착성이 높고 열산화물 발생의 문제가 있고, 흑연(Graphite)의 경우 점착성은 낮으나 분진이 발생하는 문제가 있다.In contrast, when the cover glass (glass) is used as a molding object and the temperature of the mold is set to 550℃ or higher, and Al and Pt are coated as a mold material, the adhesion is high and thermal oxide and discoloration are generated, and the mold material is kanthal ( Even when KANTHAL, an alloy composed mainly of iron and chromium, aluminum, etc.) is applied, there is a problem of high adhesion and generation of thermal oxide, and in the case of graphite, there is a problem of low adhesion but generation of dust.
또한, 파티클 발생으로 제품 불량이 발생되어 수율이 저하되고, 후속 공정인 폴리싱 시간이 증가된다.In addition, product defects occur due to particle generation, resulting in a decrease in yield, and an increase in polishing time, which is a subsequent process.
또한, 하부금형(132)은, 하부 성형면(132a)의 반대면에 배치되는 초박형 히터가 내장된 탄화규소 재질의 서셉터(150, susceptor)에 의 지지되도록 구비된다. In addition, the lower mold 132 is provided to be supported by a susceptor 150 made of silicon carbide in which an ultra-thin heater disposed on the opposite surface of the lower molding surface 132a is embedded.
서셉터(150)는, 준비되어 있는 분쇄된 원료를 바인더 시스템과 솔벤트 시스템을 믹싱 및 분산하여 슬러리를 제작하고, 목표로 하는 400㎛ 그린시트를 제작하기 위해서는 탈포공정을 거처 점도 약 20,000cps에서 테이프 케스팅을 진행한다.The susceptor 150 mixes and disperses the prepared pulverized raw material with a binder system and a solvent system to produce a slurry, and in order to produce a target 400㎛ green sheet, a tape with a viscosity of about 20,000 cps through a defoaming process. Casting proceeds.
제작된 그린시트는 수축율이 감안된 사이즈로 절단하여, 설계된 패턴을 스크린 인쇄하여 적층 후, 디라미네이션을 방지하기 위하여 WIP 공정을 진행한다.The produced green sheet is cut to a size considering the shrinkage rate, and the designed pattern is screen printed and laminated, followed by a WIP process to prevent delamination.
또한 BBO 공정은 환원 소성 전에 그린시트에 함유된 유기물을 먼저 burn out시켜 잔류 유기물을 제거한 후 200~1750℃에서 환원소성 공정을 진행하여 히터를 제작하고, 단자연결을 위해 텅스텐전극에 니켈와이어를 브레이징하여 히터를 완성한다. In addition, the BBO process burns out organic substances contained in the green sheet before reduction firing to remove residual organic substances, and then proceeds to a reduction firing process at 200 to 1750°C to produce a heater, and a nickel wire is brazed to the tungsten electrode for terminal connection. To complete the heater.
