Description
본 발명은 적층블록의 초박형 유리를 연마하기 위한 연마장치에 관한 것으로서, 더욱 상세하게는 초박형 유리와 필름을 적층하여 적층블록을 제조하고, 상기 적층블록을 컷팅한 후 이를 연마하여 커팅시 초박형 유리의 모서리에 발생된 크랙 및 스크래치를 제거하기 위한 적층블록의 초박형 유리를 연마하기 위한 연마장치에 관한 것이다.The present invention relates to a polishing apparatus for polishing ultra-thin glass of a laminated block, and more particularly, to manufacture a laminated block by laminating ultra-thin glass and a film, cut the laminated block, and grind it to obtain ultra-thin glass when cutting It relates to a polishing apparatus for polishing ultra-thin glass of a laminated block for removing cracks and scratches generated on the edge.
최근 전기, 전자 기술들이 급속도로 발전하고, 새로운 시대적 요구 및 다양한 소비자들의 요구에 맞춰 다양한 형태의 디스플레이 제품이 나오고 있으며, 그 중 화면을 접고 펼칠 수 있는 플렉시블 디스플레이에 대한 연구가 활발한 실정이다. 이에 따라 플렉서블(flexible)하면서도 굽혀지는(bendable) 유리(글라스)를 필요로 하는 다양한 응용 제품들에서 사용하기 위해, 플렉서블한 유리 물품에 대한 수요가 증가하고 있다. 예를 들면, 모바일 폰들, 테블릿들, 다른 휴대용 전자 장치들을 위한 플렉서블 디스플레이 장치들은 깨짐 현상 없이 휘어지거나 접혀야 하는 플렉서블 글라스를 포함한다. 그러나, 전통적으로 글라스(유리)는 사실상 단단한(rigid) 것으로 여겨졌고, 그러므로 글라스 대신 사용하기 위한 대체 물질들이 고려되어 왔다.In recent years, electrical and electronic technologies are rapidly developing, and various types of display products are emerging to meet the needs of the new era and the needs of various consumers. Accordingly, for use in various applications requiring flexible and bendable glass (glass), the demand for flexible glass articles is increasing. For example, flexible display devices for mobile phones, tablets, and other portable electronic devices include flexible glass that must be bent or folded without breaking. However, traditionally glass has been considered rigid in nature, and therefore alternative materials for use in place of glass have been considered.
유리(글라스)의 대체품으로서, 폴리머(polymer)로 만들어진 고분자 필름들이 플렉서블 디스플레이 장치들에서의 사용을 위해 고려되고 연구되어 왔다. 이러한 고분자 필름의 경우 기계적 강도가 약해 단순히 디스플레이패널의 스크래치를 방지하는 역할을 할 뿐 내충격성에 취약하고, 낮은 투과율을 갖는 단점이 있으며, 비교적 고가로 알려져 있다.As an alternative to glass (glass), polymer films made of polymer have been considered and studied for use in flexible display devices. In the case of such a polymer film, the mechanical strength is weak, so it merely serves to prevent scratches on the display panel, but it is weak in impact resistance, has low transmittance, and is known to be relatively expensive.
한편, 글라스가 플렉서블 디스플레이 제품에 적용하기 위해서는 0.1㎜(100㎛) 이하의 아주 얇은 초박형 글라스(ultra thin glass)로 제작되면 이를 만족하는 것으로 알려져 있다.On the other hand, it is known that if the glass is made of ultra-thin glass of 0.1 mm (100 μm) or less in order to be applied to a flexible display product, this is satisfied.
초박형 유리는 침적(Dip), 분사(Spray) 또는 Dip & Spray 방식 등을 이용하여 제조하고 연마 등의 가공방식을 통해 제조되고 있으나, 얇게 만드는 과정에서 깨짐, 크랙으로 인한 파손의 위험성이 높다.Ultra-thin glass is manufactured using dip, spray, or dip & spray methods and is manufactured through processing methods such as grinding, but there is a high risk of breakage or breakage due to cracks in the process of making thin.
아울러, 제조된 초박형 유리의 경우 단일 판을 커팅(절단)하거나 폴리싱(연마) 공정을 수행하는 경우 크랙 및 파손의 위험이 있어, 초박형 유리를 여러 겹으로 적재하여 적층블록을 제조한 후 커팅 및 연마 공정 등을 수행하고, 적층블록에서 초박형 유리와 필름을 박리하여 다음 공정으로 전달되게 된다.In addition, in the case of manufactured ultra-thin glass, there is a risk of cracks and damage when a single plate is cut (cut) or a polishing (polishing) process is performed. Process, etc. is performed, and the ultra-thin glass and film are peeled off from the laminated block and transferred to the next process.
초박형 유리를 가공하는 기술 중의 하나로서, 등록특허공보 제10-1620375호에 적층, 컷팅 공정을 포함하는 초박형 유리 가공방법이 개시되었다.As one of the techniques for processing ultra-thin glass, Patent Publication No. 10-1620375 discloses an ultra-thin glass processing method including lamination and cutting processes.
