본 발명은 액정디스펜서에 관한 것이다.The present invention relates to a liquid crystal dispenser.

액정디스펜서는, 단위패널영역으로 액정방울을 토출하는 헤드장치를 구비한다.The liquid crystal dispenser has a head device that discharges liquid crystal droplets into a unit panel area.

도 1은 종래의 헤드장치에 구비된 지지조립체와, 지지조립체에 착탈가능하게 결합된 실린더조립체, 지지조립체에 고정결합된 센서유닛을 나타낸 사시도이다.FIG. 1 is a perspective view showing a support assembly provided in a conventional head device, a cylinder assembly detachably coupled to the support assembly, and a sensor unit fixedly coupled to the support assembly.

A,B,C,D,E,F,G는 토출구멍의 위치를 나타내며, 토출구멍이 A 또는 G에 위치할 때, 노즐은 이점쇄선으로 나타내었다.FIG. 2 is a view showing nozzles provided in the cylinder assembly shown in FIG. 1, and light emitting units and light receiving units provided in the sensor unit. And the dotted arrows indicate light emitted from the light emitting portion to the light receiving portion. A, B, C, D, E, F, and G indicate the positions of the discharge holes. When the discharge holes are located at A or G, the nozzles are indicated by two-dot chain lines.

도 1 및 도 2에 도시된 바와 같이, 종래의 헤드장치는, 지지조립체(5), 실린더조립체(6), 센서유닛(7)으로 구성된다.As shown in Figs. 1 and 2, a conventional head device is composed of a support assembly 5, a cylinder assembly 6, and a sensor unit 7.

지지조립체(5)의 하면에는 제1로드(5a)와 제2로드(5b)가 수직 방향으로 구비된다. 제1로드(5a)의 끝부분과 제2로드(5b)의 끝부분에는 각각 나사산이 형성된다.A first rod 5a and a second rod 5b are provided on the lower surface of the support assembly 5 in the vertical direction. A thread is formed at the end of the first rod 5a and at the end of the second rod 5b, respectively.

제1로드(5a)의 끝부분에는 제1너트(5c)가 결합되고, 제2로드(5b)의 끝부분에는 제2너트(5d)가 결합된다.A first nut 5c is coupled to an end of the first rod 5a and a second nut 5d is coupled to an end of the second rod 5b.

실린더조립체(6)의 후면에는 제1로드(5a)가 길이방향으로 삽입되는 제1착탈홈(6a)과, 제2로드(5b)가 길이방향으로 삽입되는 제2착탈홈(6b)이 수직방향으로 구비된다.A first detachable groove 6a in which the first rod 5a is inserted in the longitudinal direction and a second detachable groove 6b in which the second rod 5b is inserted in the longitudinal direction are formed in the rear surface of the cylinder assembly 6, Direction.

실린더조립체(6)의 내부에는 액정이 저장되는 펌핑홀(미도시)이 구비되고, 펌핑홀에는 피스톤(미도시)이 삽입된다.A pumping hole (not shown) in which the liquid crystal is stored is provided in the cylinder assembly 6, and a piston (not shown) is inserted into the pumping hole.

실린더조립체(6)의 하면 중심부에는 펌핑홀과 연결된 노즐(6c)이 구비된다. A nozzle 6c connected to the pumping hole is provided at the center of the lower surface of the cylinder assembly 6. [

노즐(6c)의 중심부에는 액정방울이 토출되는 토출구멍(6d)이 구비된다.A discharge hole 6d through which the liquid crystal droplet is discharged is provided at the center of the nozzle 6c.

센서유닛(7)은, 센서블록(7a), 발광부(7b)들, 수광부(7c)들로 구성된다. 센서블록(7a)은 지지조립체(5)에 고정 설치된다.The sensor unit 7 is composed of a sensor block 7a, light emitting portions 7b, and light receiving portions 7c. The sensor block 7a is fixed to the support assembly 5.

발광부(7b)는, 센서블록(7a)의 좌측에 5개가 일정간격으로 설치되며, 빛을 방출한다.Five light emitting portions 7b are provided at the left side of the sensor block 7a at regular intervals to emit light.

수광부(7c)는, 발광부(7b)들과 각각 직선으로 마주보도록 센서블록(7a)의 우측에 5개가 일정간격으로 설치되며, 마주보는 발광부(7b)들로부터 방출된 빛을 받는다.The light receiving portion 7c is provided at a predetermined interval on the right side of the sensor block 7a so as to face the light emitting portions 7b in a straight line and receives the light emitted from the facing light emitting portions 7b.

발광부(7b)들로부터 각각 마주보는 수광부(7c)들로 빛들이 방출될 때, 발광부(7b)와 수광부(7c) 사이로 액정방울이 통과하면, 수광부(7c)가 받아들이는 빛의 양이, 빛이 액정방울을 통과하지 않을 때보다 줄어든다. 이때, 센서유닛(7)은 신호를 제어부(미도시)에 보낸다. 센서유닛(7)으로부터 신호가 오면 제어부는 액정방울 1개를 인식한다.When the liquid crystal droplet passes between the light emitting portion 7b and the light receiving portion 7c when the light is emitted from the light emitting portions 7b to the respective light receiving portions 7c, the amount of light received by the light receiving portion 7c, It is less than when light does not pass through liquid crystal droplets. At this time, the sensor unit 7 sends a signal to a control unit (not shown). When a signal comes from the sensor unit 7, the control unit recognizes one liquid crystal drop.

한편, 액정방울 1개의 양이 얼마냐에 따라, 실린더조립체(6)의 규격(펌핑홀의 내경, 피스톤의 외경등)이 달라진다. On the other hand, the size of the cylinder assembly 6 (the inner diameter of the pumping hole, the outer diameter of the piston, etc.) varies depending on how much one liquid crystal droplet is.

따라서, 액정방울 1개의 양을 변경하고자 하면, 현재 사용중인 실린더조립체(6)를, 변경하고자 하는 액정방울 1개의 양에 맞는 실린더조립체(6)로 교체하여야 한다. 교체작업은, 현재 사용중인 실린더조립체(6)를 지지조립체(5)로부터 분리시킨 다음에, 변경하고자 하는 액정방울 1개의 양에 맞는 실린더조립체(6)를 지지조립체(5)에 결합시킴으로써 이루어진다.Therefore, if the amount of one liquid crystal droplet is to be changed, the cylinder assembly 6 currently in use must be replaced with a cylinder assembly 6 corresponding to one liquid crystal drop to be changed. The replacement operation is performed by separating the cylinder assembly 6 currently in use from the support assembly 5 and then joining the cylinder assembly 6 to the support assembly 5 corresponding to one amount of the liquid crystal droplet to be changed.

현재 사용중인 실린더조립체(6)를 지지조립체(5)로부터 분리시키려면, 제1너트(5c)와 제2너트(5d)를 푼다. 그리고, 제1착탈홈(6a)과 제2착탈홈(6b)으로부터 제1로드(5a)와 제2로드(5b)를 빼내면 된다.To detach the cylinder assembly 6 currently in use from the support assembly 5, loosen the first nut 5c and the second nut 5d. Then, the first rod 5a and the second rod 5b may be pulled out from the first detachable groove 6a and the second detachable groove 6b.

변경하고자 하는 액정방울 1개의 양에 맞는 실린더조립체(6)를 지지조립체(5)에 결합시키려면, 제1착탈홈(6a)에 제1로드(5a)를, 제2착탈홈(6b)에 제2로드(5b)를 길이방향으로 각각 삽입된다. 그리고, 제1너트(5c)와 제2너트(5d)를 조이 면 된다.A first rod 5a is inserted into the first detachable groove 6a and a second rod 5b is fitted into the second detachable groove 6b to be coupled to the support assembly 5 in accordance with the amount of one liquid crystal drop to be changed And are inserted in the longitudinal direction of the second rod 5b, respectively. Then, the first nut 5c and the second nut 5d are tightened.

한편, 실린더조립체(6)는 허용오차범위내에서 제조되기 때문에, 실린더조립체(6)마다 크기, 형상등이 차이가 날 수 있다. 이로 인해, 실린더조립체(6)마다 지지조립체(5)에 결합하는 상태가 달라져, 토출구멍(6d)으로부터 토출된 액정방울이 발광부(7b)와 수광부(7c) 사이를 통과하지 못할 수 있다.On the other hand, since the cylinder assembly 6 is manufactured within the tolerance range, the size, shape, and the like may vary for each cylinder assembly 6. [ As a result, the state of coupling to the support assembly 5 varies for each of the cylinder assemblies 6, so that the liquid crystal droplets discharged from the discharge holes 6d may not pass between the light emitting portion 7b and the light receiving portion 7c.

종래에는, 센서블록(7a)이 지지조립체(5)에 고정 설치되므로, 토출구멍(6d)으로부터 토출된 액정방울이 발광부(7b)와 수광부(7c) 사이를 통과하지 못할 경우에, 토출구멍(6d)으로부터 토출된 액정방울이 발광부(7b)와 수광부(7c) 사이를 통과하도록, 센서블록(7a)을 움직일 수 없다. 따라서, 종래에는, 발광부(7b)와 수광부(7c)를 복수개 구비하였다.When the liquid crystal droplet discharged from the discharge hole 6d can not pass between the light emitting portion 7b and the light receiving portion 7c, the sensor block 7a is fixed to the support assembly 5, The sensor block 7a can not move so that the liquid crystal droplets ejected from the light emitting portions 7b and 6d pass between the light emitting portion 7b and the light receiving portion 7c. Therefore, conventionally, a plurality of light emitting portions 7b and light receiving portions 7c are provided.

예를 들어, 도 2에 도시된 바와 같이, 발광부(7b)와 수광부(7c)를 센서블록(7a)의 좌 우측에 각각 일정간격으로 5개씩 설치한다. 그러면, 실린더조립체(6)마다 크기, 형상의 차이가 작을 경우에는, 실린더조립체(6)마다 지지조립체(5)에 결합하는 상태가 달라지더라도, 토출구멍(6d)으로부터 토출된 액정방울이, 발광부(7b) 5개 각각으로부터 마주보는 수광부(7c) 5개 각각으로 방출된 5개의 빛 중 어느 하나를 통과할 수 있다.For example, as shown in FIG. 2, five light emitting portions 7b and light receiving portions 7c are provided at left and right sides of the sensor block 7a at regular intervals. If the size and shape of the cylinder assemblies 6 are small, the state in which the cylinder assemblies 6 are coupled to the support assembly 5 varies, And can pass through any one of five lights emitted to each of the five light receiving portions 7c facing each other from the five portions 7b.

그러나, 발광부(7b)와 수광부(7c)를 각각 5개로 늘렸다 하더라도, 실린더조립체(6)마다 크기, 형상의 차이가 클 경우에는, 실린더조립체(6)마다 지지조립체(5)에 결합하는 상태가 달라지면, 토출구멍(6d)이 A 또는 G에 위치할 수 있다. 토출구멍(6d)이 A 또는 G에 위치하면, 토출구멍(6d)으로부터 토출된 액정방울이, 발광부(7b) 5개 각각으로부터 마주보는 수광부(7c) 5개 각각으로 방출된 5개의 빛 중 어느 하나를 통과하지 못하게 되어, 센서유닛(7)은 토출구멍(6d)으로부터 토출된 액정방울을 감지할 수 없다.However, even if the number of the light emitting portions 7b and the number of the light receiving portions 7c are increased to five, if there is a large difference in size and shape among the cylinder assemblies 6, The discharge hole 6d may be located at A or G. When the discharge hole 6d is located at A or G, the liquid crystal droplets discharged from the discharge hole 6d are discharged from five of the light emitting portions 7b to either of the five light receiving portions 7c facing each other, The sensor unit 7 can not sense liquid droplets ejected from the ejection hole 6d.

또한, 발광부(7b)와 수광부(7c)를 각각 5개로 늘리게 되면, 센서유닛(7)의 광 용량이 발광부(7b) 5개로 동일한 양으로 분배된다. 이로 인해, 발광부(7b)와 수광부(7c) 사이로 액정방울이 통과할 때 수광부(7c)가 받는 광량과, 발광부(7b)와 수광부(7c) 사이로 액정방울이 통과하지 않을 때 수광부(7c)가 받는 광량의 차이가 크지 않게 된다. 따라서, 센서유닛(7)이 토출구멍(6d)으로부터 토출된 액정방울을 정확하게 감지할 수 없다.When the number of the light emitting portions 7b and the number of the light receiving portions 7c are increased to five, the optical capacity of the sensor unit 7 is distributed to five light emitting portions 7b in the same amount. The amount of light received by the light receiving portion 7c when the liquid crystal droplet passes between the light emitting portion 7b and the light receiving portion 7c and the amount of light received by the light receiving portion 7c when the liquid crystal droplet does not pass between the light emitting portion 7b and the light receiving portion 7c The difference in the amount of light received is not large. Therefore, the sensor unit 7 can not accurately detect liquid droplets ejected from the ejection holes 6d.

As a result, the sensor unit can accurately detect liquid droplets ejected from the ejection holes.

또한, 토출구멍으로부터 토출된 액정방울이 발광부로부터 수광부로 방출된 빛을 정확히 통과할 수 있으므로, 센서유닛은 발광부와 수광부를 1개씩만 구비하면 된다. 이로 인해, 센서유닛의 광 용량이 발광부 1개로 집중되어, 센서유닛이 토출구멍으로부터 토출된 액정방울을 정확하게 감지할 수 있다.Further, since the liquid crystal droplets ejected from the ejection holes can exactly pass the light emitted from the light emitting portion to the light receiving portion, the sensor unit may have only one light emitting portion and one light receiving portion. As a result, the optical capacity of the sensor unit is concentrated in one light emitting portion, so that the sensor unit can accurately detect liquid droplets ejected from the ejection holes.

제2로드(112)가 밀리면, 센서블록(131)은 화살표 M4 방향과 반대방향으로 힘을 받게 된다. 이러한 힘으로 인해, 노즐(121)이 삽입홈(131c)의 바닥면을 미는 방향인 화살표 M1방향과, 반대방향으로 삽입홈(131)의 바닥면이 밀리게 된다.When the second rod 112 is pushed, the sensor block 131 receives a force in a direction opposite to the direction of the arrow M4. This force pushes the bottom surface of the insertion groove 131 in a direction opposite to the direction of the arrow M1, which is the direction in which the nozzle 121 pushes the bottom surface of the insertion groove 131c.

따라서, 탄성부(134)는, 노즐(121)이 삽입홈(131c)의 바닥면을 미는 동안, 노즐(121)과 삽입홈(131c)의 바닥면의 접촉을 유지시킨다.The elastic portion 134 maintains contact between the nozzle 121 and the bottom surface of the insertion groove 131c while the nozzle 121 pushes the bottom surface of the insertion groove 131c.
