잉크젯 프린터용 헤드의 잉크 공급 구조{Ink supply structure of ink jet printer head}Ink supply structure of ink jet printer head

본 발명은 잉크젯 프린터에서 잉크 공급 구조에 관한 것으로서, 보다 상세하게는 잉크젯 프린터에서 사용되는 헤드의 크기를 최소화함과 아울러 제작 공정을 단순화할 수 있는 잉크젯 프린터용 잉크 공급 구조에 관한 것이다.The present invention relates to an ink supply structure in an inkjet printer, and more particularly, to an ink supply structure for an inkjet printer capable of simplifying a manufacturing process while minimizing the size of a head used in an inkjet printer.

일반적으로, 잉크젯 프린터는 피코리터급의 잉크 방울을 열전사등의 방법을 통해 종이에 분사함으로써, 텍스트 및 화상을 출력하는 장치인 바, 상기한 잉크 방울을 분사하기 위해 매우 미세하게 작동하는 헤드가 필요하게 된다.In general, an inkjet printer is a device that outputs text and images by spraying picoliter-grade ink droplets onto paper through a thermal transfer method, such that a head which operates very finely to spray the ink droplets is It is necessary.

상기한 헤드는 카트리지와 연결된 잉크 공급 케이스에서 잉크를 공급받는 바, 이는 도4에 도시된 바와 같이 잉크 공급공(50)이 형성된 헤드(51)와, 상기한 잉크 공급공(50)에 대응되도록 대응공(52)이 형성된 잉크 공급 케이스(53)와, 상기한 헤드(51)의 상면에 안착되어 잉크를 분출시키는 신호 인가용의 FPC(Flexible Printed Cable)(54)로 구성되어 있다.The head is supplied with ink from an ink supply case connected to the cartridge, which is to correspond to the head 51 having the ink supply hole 50 and the ink supply hole 50 as shown in FIG. An ink supply case 53 having a corresponding hole 52 is formed, and a flexible printed cable (FPC) 54 for signal application which is seated on the upper surface of the head 51 and ejects ink.

즉, 상기한 잉크 공급 케이스(53)로부터 잉크가 공급되면 헤드(51) 내부에 잉크가 충진됨과 아울러 상기한 FPC(54)에 의한 제어 신호에 의해 액츄에이터(A)가 잉크를 분출하게 되는 것이다.That is, when ink is supplied from the ink supply case 53, ink is filled in the head 51 and the actuator A ejects ink by the control signal by the FPC 54.

여기서, 상기한 헤드(51)의 구조는 도 5에 도시된 바와 같이 다수의 노즐(55)이 형성된 노즐 플레이트(56)와, 상기한 노즐 플레이트(56)의 상면에 결합됨과 아울러 리저버(57)가 형성되고 노즐(55)과 연통된 제1연통공(58)이 형성된 리저버 플레이트(59)와, 상기한 리저버 플레이트(59)의 상면에 결합됨과 아울러 리스트릭터(60)로 리저버(57)에 연통되고 제1연통공(58)과 연통되도록 제2연통공(61)이 형성된 제한 플레이트(62)와, 상기한 리스트릭터(60) 및 제2연통공(61)과 연통되도록 챔버(63)가 형성된 챔버 플레이트(64)로 이루어져 있다.Here, the structure of the head 51 is coupled to the nozzle plate 56 having the plurality of nozzles 55 formed thereon as shown in FIG. 5, the upper surface of the nozzle plate 56, and the reservoir 57. Is formed and is coupled to the reservoir plate 59 having the first communication hole 58 communicating with the nozzle 55 and the upper surface of the reservoir plate 59 as well as the restrictor 60 to the reservoir 57. Limited plate 62 having a second communication hole 61 in communication with the first communication hole 58 and the chamber 63 to communicate with the restrictor 60 and the second communication hole 61. It consists of a chamber plate 64 formed.

물론, 상기한 리저버 플레이트(59)에는 잉크 공급 케이스(53)의 대응공(52)과 연통되는 잉크 공급공(미 도시)이 형성되어 잉크가 공급된다.Of course, the reservoir plate 59 is provided with an ink supply hole (not shown) in communication with the corresponding hole 52 of the ink supply case 53 is supplied with the ink.

상기한 바와 같은 헤드의 잉크 분사 상태를 설명하면, 상기한 잉크 공급 케이스(53)에서 잉크가 잉크 공급공(50) 및 대응공(52)를 통해 리저버(57)에 공급되면, 상기한 리스트릭터(60)를 통해 챔버(63)에 잉크가 저장된다.Referring to the ink ejection state of the head as described above, when ink is supplied to the reservoir 57 through the ink supply hole 50 and the corresponding hole 52 in the ink supply case 53, the restrictor Ink is stored in the chamber 63 through 60.

잉크가 저장되어 있는 상태에서 FPC(54)의 제어에 의해 상기한 잉크가 제1, 2연통공(58, 61)을 통해 노즐(55)로 분사되면서 프린트가 이루어지게 되는 것이다.The ink is sprayed to the nozzle 55 through the first and second communication holes 58 and 61 under the control of the FPC 54 while the ink is stored, thereby printing.

그러나, 상기한 바와 같이 잉크젯 프린터의 헤드를 제작할 때 잉크를 저장하는 리저버를 일체로 제작하게 되면, 상기한 헤드의 크기가 커질 뿐만 아니라 구조가 복잡하게 됨으로써, 생산성이 저하되고 제작 공정이 어려워서 생산 능률이 저하되는 문제점이 있다.However, as described above, if the reservoir for storing the ink is integrally manufactured when the head of the inkjet printer is manufactured, the size of the head is increased and the structure is complicated, thereby reducing productivity and making the manufacturing process difficult. There is a problem of this deterioration.

따라서, 본 발명의 목적은 상기한 문제점을 해결하기 위한 것으로서, 헤드의 구조를 단순함을 이룸과 아울러 이로 인해 생산 능률 향상을 이룰 수 있는 잉크젯 프린터용 헤드의 잉크 공급 구조를 제공함에 있다.Accordingly, it is an object of the present invention to solve the above problems, and to provide an ink supply structure of a head for an inkjet printer which can achieve a simple production of the head and thereby improve production efficiency.

상기한 목적을 실현하기 위하여 본 발명은 헤드에 밀착되는 잉크 공급 케이스를 통해 잉크를 공급하도록 구성된 잉크젯 프린터용 헤드의 잉크 공급 구조에 있어서,In order to realize the above object, the present invention provides an ink supply structure of a head for an ink jet printer configured to supply ink through an ink supply case in close contact with the head.

도 1과 도 2는 본 발명에 따른 잉크젯 프린터용 헤드의 잉크 공급 구조를 도시한 분해 사시도와 조립 단면도로서, 상면에 다수의 유입공(1)이 순차 배열된 헤드(2)와, 상기한 유입공(1) 전체에 대응되도록 저장부(3)가 형성된 잉크 공급 케이스(4)로 이루어져 있다.1 and 2 are exploded perspective and assembly cross-sectional views illustrating an ink supply structure of an inkjet printer head according to the present invention, wherein a plurality of inflow holes 1 are sequentially arranged on an upper surface thereof, and the inflow described above. It consists of the ink supply case 4 in which the storage part 3 was formed so that the whole hole 1 may correspond.

또한, 상기한 헤드(2)의 저면에는 노즐(5)이 다수 형성된 노즐 플레이트(6)가 부착되어 있고, 이와 제3연통공(7)으로 연결되도록 형성됨과 아울러 리스트릭터(8)로 유입공에 각각 연결된 제한 플레이트(9)와, 상기한 리스트릭터(8) 및 제3연통공(7)으로 챔버(10)가 연결된 챔버 플레이트(11)로 구성되어 있다.In addition, a nozzle plate 6 having a plurality of nozzles 5 attached thereto is attached to the bottom of the head 2, and is formed to be connected to the third communication hole 7 and the inflow hole into the restrictor 8. It consists of a limiting plate (9) connected to each, and a chamber plate (11) connected to the chamber (10) by the restrictor (8) and the third communication hole (7).

물론, 상기한 유입공(1)은 다수가 순차 배열됨과 아울러 각각이 서로 분리되도록 형성되어 있고, 상기한 저장부(3)가 동시에 잉크를 공급할 수 있게 구성되는 것이다.Of course, the inlet hole (1) is formed so that a plurality is arranged in sequence and each is separated from each other, the storage unit 3 is configured to be able to supply ink at the same time.

상기한 바와 같이 구성하면, 종래와 같이 헤드(51) 내부에 리저버(57)가 형성되지 않고, 헤드(2) 외부인 잉크 공급 케이스(4)에 형성되기 때문에, 헤드(2)의부피를 크게 줄일 수 있게 되는 것이다.In the above-described configuration, since the reservoir 57 is not formed inside the head 51, but is formed in the ink supply case 4 outside the head 2 as in the prior art, the volume of the head 2 is greatly reduced. It will be possible.

상기한 유입공(1)으로 잉크가 유입되면 직접 리스트릭터(8)로 잉크가 유입되면서 양이 조절됨과 아울러 상기한 챔버(10)를 통해 노즐(5)로 분사되도록 구성되어 있는 것이다.When the ink flows into the inflow hole 1, the ink flows directly into the restrictor 8, the amount of which is controlled, and the nozzle 5 is sprayed through the chamber 10.

물론, 상기한 잉크 공급 케이스(4)에는 도 3에서 도시된 바와 같이 카트리지(C)를 통해 잉크가 공급된다.Of course, the ink supply case 4 is supplied with ink through the cartridge C as shown in FIG.

상기한 바와 같은 본 발명의 작용 효과를 설명하면 작업자가 헤드(2)를 조립하기 위하여, 노즐 플레이트(6)의 상면에 제한 플레이트(9)를 위치시킴과 아울러 제3연통공(7)이 노즐(5)과 연통되도록 한다.Referring to the effects of the present invention as described above, in order for the operator to assemble the head 2, the restriction plate 9 is placed on the upper surface of the nozzle plate 6 and the third communication hole 7 is provided with a nozzle. Communicate with (5).

제한 플레이트(9)가 위치되면 그 상면에 챔버 플레이트(11)가 배치됨과 아울러 챔버(10)와 리스트릭터(8) 및 제3연통공(7)이 연결된 상태를 유지하게 된다.When the limiting plate 9 is positioned, the chamber plate 11 is disposed on the upper surface thereof, and the chamber 10, the restrictor 8, and the third communication hole 7 are maintained in a connected state.

이 상태인 헤드(2)의 상면에 잉크 공급 케이스(4)를 부착하게 되는 바, 상기한 저장부(3)와 유입공(1)이 일치되도록 결합시키게 된다.The ink supply case 4 is attached to the upper surface of the head 2 in this state, and the storage unit 3 and the inlet hole 1 are coupled to each other.

저장부(3)와 다수의 유입공(1)이 일치되도록 결합되면, 실질적으로 상기한 저장부(3)가 리저버의 역할을 하게 되는 것이다.When the storage unit 3 and the plurality of inlet holes 1 are combined to match, the storage unit 3 substantially serves as a reservoir.

즉, 헤드(2)의 구성만을 보면 별도의 리저버가 없이 구성되는 바, 실질적으로 종래 헤드에 비해 리저버의 두께만큼 헤드(2)의 두께가 얇아진 상태인 바, 헤드(2)의 구성을 컴팩트하게 제작할 수 있는 것이다.That is, when only the configuration of the head 2 is viewed without a separate reservoir, the thickness of the head 2 becomes thinner as compared with the conventional head, and thus the thickness of the head 2 is compact. It can be produced.

물론, 상기한 저장부(3)는 한번에 다수의 유입공(1)과 밀착되도록 길게 형성되어 있기 때문에 다수의 유입공(1)에 균일하게 잉크를 공급할 수 있게 되는 것이다.Of course, since the storage unit 3 is formed to be in close contact with the plurality of inlet holes 1 at a time, it is possible to uniformly supply ink to the plurality of inlet holes 1.

상기한 구성의 잉크 공급 케이스(4)와 헤드(2)에 카트리지(C)로부터 잉크가 공급되면, 상기한 다수의 유입공(1)을 통해 잉크가 유입됨과 아울러 상기한 리스트릭터(8)를 통해 챔버(10) 내부로 유입된다.When ink is supplied from the cartridge C to the ink supply case 4 and the head 2 having the above-described configuration, the ink is introduced through the plurality of inflow holes 1 and the above-mentioned restrictor 8 is removed. It is introduced into the chamber 10 through.

물론, 상기한 카트리지(C)에서 공급된 잉크는 잉크 공급 케이스(4)에 형성된 저장부(3)에 저장되어 있는 상태가 된다.Of course, the ink supplied from the cartridge C is stored in the storage unit 3 formed in the ink supply case 4.

이 상태에서 프린트를 위해 FPC(54)에서 제어 신호를 출력하면 통상적으로 압전 소자 액츄에이터(PZT)의 경우 액츄에이터가 각 노즐별로 동작하면서 잉크를 노즐(5)을 통해 분사하여 프린트 동작을 하게 된다.In this state, when the control signal is output from the FPC 54 for printing, the piezoelectric element actuator PZT normally prints by injecting ink through the nozzle 5 while the actuator operates for each nozzle.

이상과 같이 본 발명은 헤드를 제작할 때, 노즐 플레이트, 제한 플레이트, 챔버 플레이트만으로 구성함과 아울러 헤드와 별도로 제작되는 잉크 공급 케이스에 잉크 공급공을 형성하여 리저버 역할을 하도록 함으로써, 헤드의 두께를 매우 얇게 구성할 수 있는 잇점이 있는 것이다.As described above, in the present invention, when the head is manufactured, only the nozzle plate, the limiting plate, and the chamber plate are formed, and the ink supply hole is formed in the ink supply case manufactured separately from the head to serve as a reservoir, thereby making the thickness of the head very large. There is an advantage that can be configured thin.

또한, 헤드의 구성을 단순화함으로써 조립 효율 및 조립 시 수율을 향상시킬 수 있는 잇점이 있는 것이다.In addition, by simplifying the configuration of the head there is an advantage that can improve the assembly efficiency and yield during assembly.
