본 발명은 LCD, PDP, OLED등과 같은 FPD의 평면 유리면이나 광학렌즈등과 같은 곡면유리 또는 금속면의 정밀하고 미세한 면을 정밀 연마할 수 있으면서 마모나 오염이 적어서 장시간 사용이 가능토록한 연마체 본체가 롤러형인 롤러형 연마체를 제공코저하는 것이다.The present invention is capable of precisely polishing the fine and fine surfaces of curved glass or metal surfaces of FPD such as LCD, PDP, OLED, etc., or optical lenses, etc. To provide a roller-type abrasive body having a roller type.

일반적으로 평면 유리면이나 금속면 또는 광학렌즈와 같은 곡면 유리면이나 금속면등을 연마하기위한 연마패드(포)는 대부분 평면으로 되어 있어서 그 평면 연마패드를 바닥에 놓고 피연마체를 위에서 전후 또는 좌우회전하거나 왕복하면서 연마하게되므로 단시간에 연마포(패드)가 마모, 멸실되거나 오염되어 일회이상 재사용이 거의 불가능하므로 연마패드의 손실이 많고 많이 소요되는 등 경제적 손실이 많은 결점이 있었다.Generally, a polishing pad (foam) for polishing a curved glass surface or a metal surface such as a flat glass surface or a metal surface or an optical lens is mostly flat, so the flat polishing pad is placed on the floor and the polishing object is rotated back and forth or left and right. Since the polishing is performed while reciprocating, the polishing cloth (pad) is worn out, lost or contaminated in a short time, so that it is almost impossible to reuse it more than once.

본 발명은 상기한 바와같은 종래의 평면 연마패드의 결점을 배제하여 연마체 본체를 롤러형태로 만들어 연마체를 고정위치에서 회전하면서 정지된 피연마체를 연마하거나 피연마체와 롤형 연마체를 이동시키면서 연마체를 회전시켜 연마할 수가 있어서 다양한 형태로 사용이 가능한 장점이 있고, 롤러형 연마체 본체를 회전시키면서 연마가 가능하여 연마체 본체의 마모나 훼손 또는 오염이 적게되고 따라 서 하나의 연마체 본체를 장시간 반복하여 사용할 수가 있으므로 원가가 절감됨은 물론 단시간에 많은 양의 연마를 할 수 있어서 경제적인 효과가 배가되는 롤러형 연마체를 제공코저하는 것으로서 이를 첨부된 도면을 참조하면서 상세히 설명하면 다음과 같다.
The present invention eliminates the drawbacks of the conventional planar polishing pad as described above, and makes the abrasive body main body in the form of a roller to polish the stationary polishing object while rotating the polishing body at a fixed position, or while polishing the polishing object and the roll-shaped polishing body. It can be polished by rotating the sieve, which can be used in various forms, and it is possible to polish by rotating the roller-shaped abrasive body, thereby reducing wear, damage, or contamination of the abrasive body. Since it can be used repeatedly for a long time, the cost is reduced, and a large amount of polishing can be performed in a short time, thereby providing a roller-type abrasive body that doubles the economic effect. This will be described in detail with reference to the accompanying drawings. .

평면유리나 광학렌즈의 곡면 및 금속면의 정밀연마를 위한 연마체에 있어서,
상기 연마체의 본체(2)는 발포 폴리우레탄수지만으로된 것이나, 발포 폴리우레탄수지에 공지의 셀륨옥사이드, 산화알루미늄, 산화철, 실리콘카바이드, 산화크롬, 산화규소, 다이어몬드, 지르코니아(산화질리코늄)중에서 선택된 연마제중 어느 한가지를 혼합한 혼합물로 된 것이나, 폴리우레탄 프리폴리머에 상기한 각종 연마제중에서 선택된 어느 한가지를 내포한 활성수소함유 화합물을 혼합한 혼합물로 된 것중에서 선택된 어느 한가지의 통상적인 발포 폴리우레탄 연마패드 제조용 원료를 사용하여 원통형 롤러형태로 발포성형하거나, 직포나 부직포를 사용하여 먼저 상기 연마체의 본체(2)와 같은 롤러형태로 성형한 후, 상기 직포나 부직포로된 롤러형태에 상기한 통상적인 발포 폴리우레탄 연마패드 제조용 원료를 함침시켜 원통형 롤러형태로 발포 성형하되, 상기 연마체의 본체(2)중앙에는 가로방향 축봉(1)을 삽입 설치하고, 상기 연마체의 본체(2) 표면은 다수개의 기포홈(3)을 가지면서 전체가 평활면으로된 것으로 구성된다.
이상과 같이 구성되는 연마체는 롤러 형태이므로 회전시키면서 연마할 수가 있어서 연마에 의한 마모율이 적고 장기간 사용이 가능한 장점이 있다.
또한 연마체 본체(2)에는 다수개의 기포홈(3)이 형성되어 있으므로 연마효과가 우수한 특징이 있는 것이다.In the polishing body for precise polishing of curved surfaces and metal surfaces of flat glass or optical lenses,
The main body 2 of the abrasive body is made of only a foamed polyurethane resin, but known cerium oxide, aluminum oxide, iron oxide, silicon carbide, chromium oxide, silicon oxide, diamond, zirconia (siliconium oxide) known in the foamed polyurethane resin Any one conventional foamed polyurethane selected from the group consisting of a mixture of any one selected from among the above abrasives, or a mixture of an active hydrogen-containing compound containing any one selected from the above various abrasives in a polyurethane prepolymer. Foam molding in the form of a cylindrical roller using the raw material for manufacturing the polishing pad, or first using a woven or non-woven fabric is molded in the same roller shape as the main body 2 of the abrasive body, and then the rollers made of the woven or nonwoven fabric Impregnated with raw materials for the manufacture of conventional polyurethane foam pads, Foam molding, the horizontal shaft rod (1) is inserted in the center of the main body (2) of the abrasive body, the surface of the main body (2) of the abrasive body has a plurality of bubble grooves (3) as a whole smooth surface It consists of.
Since the abrasive is constituted as a roller, it can be polished while being rotated, so that the wear rate by polishing is small and the long term can be used.
In addition, since the plurality of bubble grooves 3 are formed in the abrasive body 2, the polishing effect is excellent.

또 상기에서 연마체의 본체(2)를 그 속에 직포나 부직포로된 롤러형태가 매립된 것으로 구성할 경우에는 발포 폴리우레탄 연마패드 제조원료가 적게 들게되므로 원가절감이 됨은 물론 연마체 본체(2)의 강도가 우수하여 강력한 연마를 필요로할 때에 우수한 연마효과를 발휘하게 된다.In addition, when the main body 2 of the abrasive body is formed by embedding a roller or a nonwoven fabric therein, the polyurethane foam pad manufacturing raw material is less costly, the cost saving, as well as the abrasive body (2) When the strength is excellent and strong polishing is required, it shows excellent polishing effect.

이상과 같이 구성된 본 발명 연마체는 본체가 롤러타입으로 형성되어 있어서 축봉(1)을 양측 축받이(미도시)에 걸어서 제자리에서 회전시키거나 이동하면서 회전시켜 피연마체를 연마하게되면 연마면이 곡면이어서 피연마체에 밀착성이 좋아 정밀 연마 및 강력한 연마가 가능하여 연마효과가 뛰어나고 연마롤러가 회전되면서 연마가 행해지므로 롤의 마모도 적고 오염도 적어서 장시간 사용이 가능하며 따라서 원가절감등 경제적인 효과가 있으며 자주 교체할 필요가 없으므로 단시간에 많은 양의 연마효과를 얻을 수 있는 경제적인 효과도 얻을 수 있는 것이다.The abrasive body of the present invention constituted as described above has a main body formed in a roller type so that the polishing surface is curved when the shaft 1 is polished by rotating or moving while rotating the shaft 1 in place on both bearings (not shown). It has good adhesion to the to-be-processed object, so it can be used for a long time because it has excellent polishing effect and can be polished as the polishing roller rotates. Since there is no need, it is possible to obtain an economic effect that can obtain a large amount of polishing effect in a short time.
