Description

액정공급장치 {APPARATUS FOR SUPPLYING LIQUID CRYSTAL}[0001] APPARATUS FOR SUPPLYING LIQUID CRYSTAL [0002]

본 발명은 액정공급장치에 관한 것이다.The present invention relates to a liquid crystal supply device.

LCD(Liquid Crystal Display)는 컬러를 구현하기 위해 컬러필터(Color Filter)층이 구비된 마더기판, 박막트랜지스터(Thin Film Transistor)가 구비된 마더기판, 마더기판들 사이에 구비된 액정층을 포함한다.LCD (Liquid Crystal Display) includes a mother substrate having a color filter layer, a mother substrate having a thin film transistor, and a liquid crystal layer provided between mother substrates to implement colors .

LCD는 액정층을 구성하는 액정분자를 구동소자로 구동하여, 액정층을 투과하는 광량을 제어함으로써 화상을 표시한다.The LCD displays images by driving liquid crystal molecules constituting the liquid crystal layer as driving elements and controlling the amount of light transmitted through the liquid crystal layer.

마더기판에는 적어도 한 개 이상의 단위패널영역들이 정의된다. 단위패널영역은 액정방울들이 토출되는 영역이다.At least one or more unit panel regions are defined in the mother substrate. The unit panel area is a region in which 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 has a head device. The head device discharges the liquid crystal into the liquid crystal droplets through the nozzles into the unit panel area. A liquid crystal bottle is detachably mounted on the head device. The liquid crystal bottle has a cap. The stopper is provided with an injection port.

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 includes a liquid crystal tank in which a liquid crystal is stored, a tube support tube, a tube having one end connected to the liquid crystal tank and the other end inserted into the tube support tube, a pressure supply unit for supplying pressure into the liquid crystal tank, And a pushing unit for releasing the pushing and for preventing or flowing the liquid crystal through the tube.

액정공급장치는, 튜브지지관을 주입구에 삽입시킨 후, 압력공급유닛을 작동시켜, 액정탱크에 저장된 액정을, 튜브와 주입구를 통해서 액정병으로 공급한다.In the liquid crystal supply device, after inserting the tube support tube into the injection port, the pressure supply unit is operated to supply the liquid crystal stored in the liquid crystal tank to the liquid crystal bottle through the tube and the injection port.

누름유닛은, 튜브가 삽입되는 제1블록과, 튜브를 누르거나 그 누름을 푸는 제2블록과, 제2블록을 구동하는 구동부를 구비한다.The pressing unit includes a first block into which a tube is inserted, a second block that presses the tube or releases the tube, and a driving unit that drives 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 into the unit panel area, liquid crystal tanks, liquid crystal bottles and tubes must be replaced with new ones so that the liquid crystal of the other type and the liquid crystal of the other kind do not mix with each other.

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 an 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 hand of the operator may get caught between the first block and the second block.

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

상기 목적을 달성하기 위한, 액정공급장치는, 액정이 저장된 액정탱크; 상기 액정탱크와 일단이 연결된 튜브; 상기 튜브를 누르거나 그 누름을 풀어서 상기 튜브를 통해서 액정이 흐르지 못하게 하거나 흐르게 하는 누름유닛;을 포함하며, 상기 누름유닛은, 베이스판; 상기 베이스판에 회전가능하게 설치되며, 상기 튜브가 삽입된 제1블록; 상기 제1블록에 삽입된 튜브를 누르거나 그 누름을 푸는 제2블록; 및 상기 제2블록을 구동하는 구동부;를 포함한다.In order to achieve the above object, a liquid crystal supply device includes: a liquid crystal tank in which liquid crystal is stored; A tube connected at one end to the liquid crystal tank; And a pressing unit for pressing or releasing the tube so that the liquid crystal can not flow or flow through the tube, the pressing unit comprising: a base plate; A first block rotatably installed on the base plate, the first block having the tube inserted therein; A second block that presses or releases the tube inserted into the first block; And a driving unit for driving the second block.

본 발명을 사용하면, 작업자가 튜브가 삽입된 제1블록을 회전시켜 젖힌 상태에서, 튜브를 교체하므로, 구동부가 오작동하더라도, 작업자의 손이 제2블록과 제1블록 사이에 끼지 않는다. 따라서, 작업자가 안전하게 기존 튜브를 새 튜브로 교체할 수 있다.According to the present invention, since the operator replaces the tube while rotating the first block in which the tube is inserted, the operator's hand does not get caught between the second block and the first block, even if the driving unit malfunctions. Therefore, the operator can safely replace the existing tube with the new tube.

If the tube T is not pressed, the liquid crystal flows through the tube T.

도 3에 도시된 바와 같이, 제1블록(154)은, 베이스판(151)에 회전가능하게 설치된다. 이를 위해, 제1블록(154)에는 구멍(154c)이 구비되고, 구멍(154c)에는 축(155)이 삽입되고, 베이스판(151)에는 축(155)의 양단을 지지하는 지지대(156)들이 구비된다.As shown in FIG. 3, the first block 154 is rotatably installed on the base plate 151. The first block 154 is provided with a hole 154c and the hole 154c is provided with a shaft 155. The base plate 151 is provided with a support base 156 for supporting both ends of the shaft 155, Respectively.

이하, 작업자가 기존 튜브(T)를 새 튜브(T)로 교체하는 순서를 설명한다.Hereinafter, a procedure for replacing the existing tube T with the new tube T will be described.

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 operator rotates the first block 154 in the direction of the arrow R1. The existing tube T is pulled out from the first groove 154a. The new tube T is inserted into the first groove 154a. In the direction of the arrow R2, the first block 154 is rotated and returned 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.The operator removes the existing tube T and inserts the new tube T in a state in which the first block 154 is rotated so that the operator's hand can replace the existing tube T with the new tube T It is not located between the second block 159 and the first block 154. [ Therefore, even if the driving unit 152 malfunctions and the second block 159 advances, the operator does not hurt his / her hands.
