LCD는 액정층을 구성하는 액정분자를 구동소자로 구동하여, 액정층을 투과하는 광량을 제어함으로써 화상을 표시한다.The LCD displays an image by driving the liquid crystal molecules constituting the liquid crystal layer by driving elements to control the amount of light passing through the liquid crystal layer.

마더기판에는 적어도 한 개 이상의 단위패널영역들이 정의된다. 단위패널영역은 액정방울들이 토출되는 영역이다.At least one unit panel region is defined on the mother substrate. The unit panel region is a region where liquid crystal droplets are discharged.

액정디스펜서는, 헤드장치를 구비한다. 헤드장치는, 액정을 단위패널영역으로 노즐을 통해 액정방울로 토출시킨다. 헤드장치에는 액정병이 착탈 가능하게 장착된다. 액정병은 마개를 구비한다. 마개에는 주입구가 구비된다.The liquid crystal dispenser includes a head device. The head apparatus discharges the liquid crystal to the liquid crystal droplets through the nozzle to the unit panel region. The liquid crystal bottle is detachably attached to the head device. The liquid crystal bottle has a stopper. The stopper is provided with an injection hole.

액정공급장치는, 액정이 저장된 액정탱크, 튜브지지관, 일단이 액정탱크와 연결되고 타단이 튜브지지관에 삽입된 튜브, 액정탱크의 내부로 압력을 공급하는 압력공급유닛, 튜브를 누르거나 그 누름을 풀어서 튜브를 통해서 액정이 흐르지 못 하게 하거나 흐르게 하는 누름유닛을 구비한다.The liquid crystal supply device is a liquid crystal tank, a tube support tube, a liquid crystal tank is stored, one end is connected to the liquid crystal tank and the other end is inserted into the tube support tube, the pressure supply unit for supplying pressure to the inside of the liquid crystal tank, press the tube or A press unit is provided to release the press to prevent or flow the liquid crystal through the tube.

액정공급장치는, 튜브지지관을 주입구에 삽입시킨 후, 압력공급유닛을 작동시켜, 액정탱크에 저장된 액정을, 튜브와 주입구를 통해서 액정병으로 공급한다.The liquid crystal supply device inserts the tube support tube into the inlet, and then operates the pressure supply unit to supply the liquid crystal stored in the liquid crystal tank to the liquid crystal bottle through the tube and the inlet.

누름유닛은, 튜브가 삽입되는 제1블록과, 튜브를 누르거나 그 누름을 푸는 제2블록과, 제2블록을 구동하는 구동부를 구비한다.The pressing unit includes a first block into which the tube is inserted, a second block pressing or releasing the tube, and a driving unit for driving the second block.

한편, 단위패널영역으로 토출 될 액정의 종류를 바꾸려면, 기존 액정과 다른 종류의 액정이 서로 섞이지 않게, 액정탱크, 액정병, 튜브를 새것들로 교체해야 한다.On the other hand, in order to change the type of liquid crystal to be discharged to the unit panel area, the liquid crystal tank, the liquid crystal bottle, and the tube should be replaced with new ones so that the existing liquid crystal does not mix with other kinds of liquid crystals.

작업자가, 기존 튜브를 새것으로 교체하기 위해서는, 제1블록에 삽입된 기존 튜브를 빼내고 새 튜브를 제1블록에 삽입해야 한다. 이때, 구동부가 오작동하여 제2블록을 밀게 되면, 작업자의 손이 제1블록과 제2블록 사이에 끼어 다칠 수 있다.To replace the existing tube with a new one, the operator must remove the existing tube inserted in the first block and insert the new tube into the first block. At this time, if the driving unit malfunctions and pushes the second block, the operator's hand may be injured between the first block and the second block.

본 발명의 목적은 작업자가 기존 튜브를 새 튜브로 안전하게 교체할 수 있는액정공급장치를 제공하는 데 있다.An object of the present invention is to provide a liquid crystal supply device that allows the operator can safely replace the existing tube with a new tube.

To this end, the first block 154 is provided with a hole 154c, a shaft 155 is inserted into the hole 154c, and a support 156 supporting both ends of the shaft 155 in the base plate 151. Are provided.

이하, 작업자가 기존 튜브(T)를 새 튜브(T)로 교체하는 순서를 설명한다.Hereinafter, a description will be given of the operator replacing the existing tube T with a new tube (T).

작업자는 화살표 R1방향으로, 제1블록(154)을 회전시켜 젖힌다. 제1홈(154a)으로부터 기존 튜브(T)를 빼낸다. 새 튜브(T)를 제1홈(154a)에 삽입한다. 화살표 R2방향으로, 제1블록(154)을 회전시켜 원위치로 복귀시킨다.The worker rotates and rotates the first block 154 in the direction of the arrow R1. The existing tube T is removed from the first groove 154a. Insert a new tube (T) into the first groove (154a). In the direction of arrow R2, the first block 154 is rotated to return to the original position.

작업자가 제1블록(154)을 회전시켜 젖힌 상태에서, 기존 튜브(T)를 빼내고, 새 튜브(T)를 삽입하므로, 작업자의 손이, 기존 튜브(T)를 새 튜브(T)로 교체할 때, 제2블록(159)과 제1블록(154) 사이에 위치하지 않는다. 따라서, 구동부(152)가 오작동하여, 제2블록(159)을 전진시키더라도, 작업자가 손을 다치지 않는다.Since the operator rotates the first block 154 and flips it, the operator removes the existing tube T and inserts a new tube T. Therefore, the operator's hand replaces the existing tube T with the new tube T. Do not lie between the second block 159 and the first block 154. Therefore, even if the driving unit 152 malfunctions and moves the second block 159 forward, the operator does not hurt his hand.
