불소수지제품 제조장치{Fluorine resin product manufacturing device}Fluorine resin product manufacturing device {Fluorine resin product manufacturing device}

본 발명은 불소수지제품 제조장치에 관한 것으로서, 더욱 상세하게는 사출 성형에 의해 제작된 불소수지 제품을 지그로부터 안전하고 용이하며, 흠집없이 분리시킬 수 있는 불소수지제품 제조장치에 관한 것이다.The present invention relates to a fluororesin product manufacturing apparatus, and more particularly, to a fluororesin product manufacturing apparatus capable of safely, easily and flawlessly separating a fluororesin product manufactured by injection molding from a jig.

반도체 제조공정에서 실리콘 웨이퍼 표면의 청결도는 반도체 생산 수율 및 반도체 품질에 직접적인 영향을 미치므로, 반도체 제조공정에서는 실리콘 웨이퍼 표면에 부착된 이물질을 제거하기 위해 다양한 종류의 세정제가 사용된다.Since the cleanliness of the silicon wafer surface in the semiconductor manufacturing process directly affects the semiconductor production yield and semiconductor quality, various types of cleaning agents are used in the semiconductor manufacturing process to remove foreign substances attached to the surface of the silicon wafer.

세정제로는 매우 강한 산성을 갖거나 침투성이 높은 황산, 염산, 과산화수소 수용액 등이 사용되며, 세정제가 유동하는 관로는 주로 높은 내부식성 및 내화학성을 가진 불소수지(fluorine resin)로 구성된다.As the cleaning agent, sulfuric acid, hydrochloric acid, hydrogen peroxide aqueous solution, etc. having very strong acidity or high permeability are used, and the pipe through which the cleaning agent flows is mainly composed of fluorine resin having high corrosion resistance and chemical resistance.

또한, 다수의 관로가 서로 맞닿는 부분을 커버하는 패킹부재(packing) 역시 관로와 마찬가지로 높은 내부식성 및 내화학성을 갖는 불소수지가 널리 사용된다.In addition, a fluororesin having high corrosion resistance and chemical resistance is also widely used for a packing member covering a portion where a plurality of conduits come into contact with each other as well as the conduit.

불소수지는 내부식성, 내화학성 등의 물성은 뛰어나지만 사출 등의 방법을 이용하여 제품(예컨대, 세정제 유동 관로)을 제조할 경우에는 온도변화에 따른 팽창/수축에 의해 치수정밀도가 크게 낮아지는 특성이 있다. 이를 위해 그 제작과정에서 열수축에 의한 변형되는 범위를 제한하는 지그가 사용된다.Fluorine resin has excellent physical properties such as corrosion resistance and chemical resistance, but when a product (eg, detergent flow pipe) is manufactured using a method such as injection, the dimensional accuracy is greatly reduced due to expansion / contraction due to temperature change. there is To this end, a jig that limits the range of deformation due to heat shrinkage during the manufacturing process is used.

지그를 이용한 패킹부재 제조방법에 관한 종래기술은 대한민국 등록특허 제10-1531768호에 게시되어있다.Prior art related to a method for manufacturing a packing member using a jig is published in Korean Registered Patent No. 10-1531768.

상술한 종래기술에 따르면, 사출 등의 방법을 이용하여 1차 성형된 패킹부재 내측에 지그를 삽입한 후 열처리함으로써, 패킹부재가 정확한 길이의 내경을 가지도록 한다. According to the prior art described above, by inserting a jig inside the firstly molded packing member using a method such as injection, and then heat-treating, the packing member has an inner diameter of an accurate length.

다만, 상기 종래기술에서는 고정된 길이의 외경을 가진 지그로 인해, 하기의 여러 문제들이 발생하게 된다.However, in the prior art, due to the jig having an outer diameter of a fixed length, the following problems occur.

첫 번째로, 패킹부재의 내주면과 지그의 외주면 간의 마찰로 인해, 지그를 패킹부재 내측에 삽입하거나 탈거할 때 지나치게 많은 힘이 필요한 문제가 있다.First, due to friction between the inner circumferential surface of the packing member and the outer circumferential surface of the jig, excessive force is required when inserting or removing the jig from the inside of the packing member.

즉, 지그를 패킹부재에 삽탈할 때 해머와 같은 무거운 부재로 지그를 다수 회 타격해야 하는 번거로움이 있다.That is, when inserting and removing the jig from the packing member, it is inconvenient to hit the jig multiple times with a heavy member such as a hammer.

두 번째로, 종래의 지그는 특정 길이의 내경을 가진 패킹부재에만 사용될 수 있어, 다양한 크기의 패킹부재를 제작하기 위해서는 사이즈가 다른 여러 개의 지그를 구비해야만 한다. Second, a conventional jig can be used only for a packing member having an inner diameter of a specific length, so that several jigs of different sizes must be provided in order to manufacture packing members of various sizes.

세 번째로, 지그가 패킹부재 내주면을 슬라이딩하는 과정에서, 패킹부재의 내주면에 스크래치가 발생하여 치수 정밀도가 저하되는 단점이 있다.Thirdly, in the process of the jig sliding the inner circumferential surface of the packing member, scratches occur on the inner circumferential surface of the packing member, resulting in reduced dimensional accuracy.

And, after the second support block 200 and the fourth support block 400 are separated, as shown in FIG. 5, the first support block 100 and the third support block 300 are fluororesin products ) can be easily separated from the inner circumferential surface of the

이와 같이 본 발명에 따른 불소수지제품 제조장치는 풀림단계 이후에 지그유닛(10)을 불소수지제품(1)으로부터 분리하는 과정에서 불소수지제품(1)에 손상이 없고 지그유닛(10)을 분리하는데 큰 힘이 없이도 분리가 가능한 장점이 있다.As described above, in the fluororesin product manufacturing apparatus according to the present invention, in the process of separating the jig unit 10 from the fluororesin product 1 after the annealing step, the fluororesin product 1 is not damaged and the jig unit 10 is separated. It has the advantage of being able to separate without much force.

이상에서 설명한 본 발명에 따른 불소수지제품 제조장치는 첨부된 도면을 참조로 설명하였으나 이는 예시적인 것에 불과하며, 당해 기술분야에서 통상의 지식을 가진 자라면 이로부터 다양한 변형 및 균등한 타 실시 예가 가능하다는 점을 이해할 것이다. The apparatus for manufacturing a fluororesin product according to the present invention described above has been described with reference to the accompanying drawings, but this is only exemplary, and various modifications and other equivalent embodiments can be made by those skilled in the art. will understand that
