Abstract

액정을 일정한 크기의 입자로 무화시키는 초음파를 이용한 노즐 액정 적하 장치가 개시된다. 본 발명에 따른 초음파를 이용한 노즐 액정 적하 장치는 액정이 저장되는 저장공간이 구비된 시린지, 상기 시린지에 저장된 액정을 공급받아 상기 액정을 무화시켜 기판상에 적하시키는 무화적하유닛 및 상기 시린지의 저장공간에 저장된 액정을 상기 무화적하유닛에 공급하기 위하여 압력을 가하는 가스공급유닛을 포함하여 구성되며, 상기 무화적하유닛은 상기 시린지와 연통되는 액정주입구가 구비된 케이스, 상기 케이스 내부에서 상기 케이스에 결합되며, 중앙에서 상하 방향으로 끝단의 토출구까지 관통되어 상기 케이스의 액정주입구와 상기 토출구를 연통시키는 액정유로가 형성된 노즐몸체, 상기 노즐몸체 상에 구비되어, 상기 노즐몸체를 상하방향으로 진동시키는 초음파 발진유닛 및 상기 노즐몸체와 일정거리 이격된 공간을 가지도록 상기 노즐몸체 하부에 구비되고, 상기 이격된 공간을 통해 압축공기가 분사되어 상기 노즐몸체의 토출구를 통해 상기 기판상에 적하되는 액정이 일정 범위내의 영역 범위를 벗어나는 것을 방지하기 위하여 상기 토출구에서부터 상기 기판까지 에어커튼을 형성시키는 분산차단부를 포함하여 구성된다.
