Description

잉크분사방법 및 그 장치Ink spraying method and apparatus

본 발명은 잉크젯 프린트 헤드에 적용되는 잉크분사방법 및 그 장치에 관한 것으로서, 특히 자성물질을 이용한 잉크분사방법 및 그 장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ink jetting method and apparatus therefor applied to an inkjet print head, and more particularly, to an ink jetting method using a magnetic material and a device thereof.

종래의 DOD(drop-on-demand) 잉크젯 프린트 헤드에 적용된 기술은 크게 표면발열체를 이용한 가열방식과 압전체를 이용한 압전방식이 있다.The technology applied to the conventional drop-on-demand (DOD) inkjet printhead is mainly a heating method using a surface heating element and a piezoelectric method using a piezoelectric body.

표면발열체를 이용한 가열방식은 도 1과 같이 기판(1) 위에 하부절연층(2), 발열체(3), 전극(4,5), 상부절연층(6), 보호층(7)을 차례로 형성하고, 보호층(7)과 노즐판(9)과 보호층(7) 사이에 스페이서(8)를 끼워 잉크챔버(10)를 형성하여 된다. 여기서 잉크챔버(10)는 도시되지 않은 잉크탱크와 연결되어 있고, 양측 전극(4,5)은 구동신호 발생기(12)와 연결된다. 구동신호 발생기(12)로부터 전극(4,5)을 통해 발열체(3)에 구동신호를 인가하면 발열체(3)가 가열되고 잉크챔버(10) 내의 잉크(13)가 비등하게 된다. 이때 잉크챔버(11) 내에 기포(14)가 발생되며, 발생된 기포(14)가 잉크챔버(10) 내의 잉크(13)를 노즐판(8)의 노즐(11) 밖으로 밀어냄으로써 토출잉크(15)를 만든다. 토출잉크(15)는 구동신호, 즉 프린트 신호에 따라 분사되는 것이다.In the heating method using the surface heating element, the lower insulating layer 2, the heating element 3, the electrodes 4 and 5, the upper insulating layer 6, and the protective layer 7 are sequentially formed on the substrate 1 as shown in FIG. 1. Then, the ink chamber 10 is formed by sandwiching the spacer 8 between the protective layer 7, the nozzle plate 9, and the protective layer 7. Here, the ink chamber 10 is connected to an ink tank (not shown), and both electrodes 4 and 5 are connected to the drive signal generator 12. When a drive signal is applied from the drive signal generator 12 to the heat generator 3 through the electrodes 4 and 5, the heat generator 3 is heated and the ink 13 in the ink chamber 10 is boiled. At this time, bubbles 14 are generated in the ink chamber 11, and the generated bubbles 14 push the ink 13 in the ink chamber 10 out of the nozzle 11 of the nozzle plate 8 to discharge ink 15. ) The discharge ink 15 is ejected in accordance with a drive signal, that is, a print signal.

한편, 압전체를 이용한 압전방식은 도 2와 같이, 기판(16), 다이아프람(17), 압전소자(18), 스페이서(19), 노즐판(20)으로 구성된다. 구동신호 발생기(23)로부터 압전소자(18)에 구동신호를 인가하면 압전소자(18)는 기계적으로 신축되며, 이러한 압전소자(18)의 신축작용으로 잉크챔버(21)내의 잉크(24)가 노즐(22) 밖으로 밀려남으로써 토출잉크(25)가 만들어진다.On the other hand, a piezoelectric method using a piezoelectric body is composed of a substrate 16, a diaphragm 17, a piezoelectric element 18, a spacer 19, and a nozzle plate 20 as shown in FIG. When the driving signal is applied from the driving signal generator 23 to the piezoelectric element 18, the piezoelectric element 18 is mechanically stretched and the ink 24 in the ink chamber 21 is stretched by the stretching operation of the piezoelectric element 18. The discharge ink 25 is produced by being pushed out of the nozzle 22.

상기한 종래기술에 있어서, 가열방식은 충분한 기포를 생성하는데 시간이 다소 소요되어 잉크의 토출속도, 즉 인쇄속도 향상에 한계가 있으며, 발열체의 특성이 주변온도의 영향으로 잘 변화되어 안정된 성능을 기대하기 어렵다. 이와 달리 압전방식에서는, 우수한 성능이 발휘되나 고가의 압전소자를 사용하므로 가격이 비싼 단점이 있다. 그리고 양자 공히 발열체나 압전소자를 전극, 절연층, 보호층 등과 잘 조화시켜야 하므로 그 제조공정이 까다로워 그만큼 수율이 저조한 것이다.In the above-described prior art, the heating method takes a long time to generate a sufficient bubble, there is a limit in improving the discharge speed of the ink, that is, the printing speed, the characteristics of the heating element is well changed due to the influence of the ambient temperature to expect stable performance Difficult to do On the other hand, in the piezoelectric method, excellent performance is exhibited, but an expensive piezoelectric element is used, and thus, the price is expensive. In addition, since both the heating element and the piezoelectric element must be well harmonized with the electrode, the insulating layer, the protective layer, and the like, the manufacturing process is difficult and the yield is low.

본 발명의 목적은 상기한 문제점을 감안하여 종래와는 전혀 다른 방식의 간단한 구조로서 제작이 쉽고 안정된 동작특성과 잉크의 토출 압력과 속도의 제어가 가능한 자성물질을 이용한 잉크분사방법 및 그 장치를 제공하는데 있다.It is an object of the present invention to provide an ink spraying method and apparatus using a magnetic material which is easy to manufacture, stable operation characteristics and control of ejection pressure and speed of ink as a simple structure of a completely different method in view of the above problems. It is.

상기한 목적을 달성하기 위한 본 발명의 잉크분사방법은,Ink spraying method of the present invention for achieving the above object,

자계내에서 자화될 수 있는 금속 미립자 등의 자성물질이 혼합된 잉크를 솔레노이드코일(solenoid coil) 내부로 공급하고, 그 솔레노이드코일에 전기신호를 인가하여 그 중공부에 있는 잉크에 혼합된 자성물질이 자화됨으로써 이동하게 되는 전자적(電磁的) 추력에 의하여 자성물질과 함께 잉크를 분사하는 것을 그 특징으로 한다.The ink mixed with magnetic material such as metal particles which can be magnetized in the magnetic field is supplied into the solenoid coil, and the magnetic material mixed with the ink in the hollow part is applied by applying an electrical signal to the solenoid coil. The ink is ejected together with the magnetic material by the electronic thrust which is moved by being magnetized.

또한 상기한 목적을 달성하기 위하여, 자계내에서 자화될 수 있는 금속 미립자 등의 자성물질이 혼합된 잉크를 분사하는 본 발명의 잉크분사장치는, 그 자성물질이 혼합된 잉크를 공급하는 공급수단, 이 공급수단으로부터 공급되는 잉크를 수용하는 중공부를 가지며 전기신호로 여자되어 그 중공부에 수용된 잉크에 혼합된 자성물질을 자화시켜 전자적 추력으로 이동시킬 수 있는 솔레노이드코일, 이 솔레노이드코일의 중공부로부터 잉크를 토출시키기 위한 노즐, 그리고 솔레노이드코일의 전기신호를 발생하는 신호 발생기를 포함하는 것이다.Further, in order to achieve the above object, the ink ejection device of the present invention for injecting ink mixed with magnetic materials such as metal particles that can be magnetized in a magnetic field, supply means for supplying the ink mixed with the magnetic material, A solenoid coil having a hollow portion for accommodating ink supplied from the supply means, which is excited by an electrical signal and magnetizes a magnetic material mixed with the ink contained in the hollow portion, and moves by electronic thrust, the ink from the hollow portion of the solenoid coil. And a signal generator for generating an electrical signal of the solenoid coil.

이와 같이 본 발명은 자성물질이 혼합된 잉크를 사용하고 이것을 솔레노이드코일의 전자적 추력을 이용하여 분사하는 것으로서 그 바람직한 실시예를 첨부된 도면을 참조하여 상세하게 설명하면 다음과 같다.As such, the present invention uses ink mixed with a magnetic material and sprays the same using the electronic thrust of the solenoid coil, which will be described in detail with reference to the accompanying drawings.

본 발명에 따른 잉크분사방법은 그 구체화된 잉크분사장치가 도시된 도면을 참조할 때 더 잘 이해될 것이다. 본 발명의 잉크분사장치는, 도 3에 도시된 바와 같이, 기판(26), 이 기판(26) 위에 형성된 보호층(27), 이 보호층(27) 위에 설치되어 잉크(28)를 수용하는 잉크챔버(29)를 형성하는 스페이서(30), 잉크챔버(29)로부터 잉크(28)를 토출시키기 위한 노즐(32)을 가지는 노즐판(31), 그리고 잉크챔버(29) 내에 위치된 솔레노이드코일(33)로 구성된다.The ink ejection method according to the present invention will be better understood when referring to the drawings in which the specified ink ejection apparatus is shown. As shown in FIG. 3, the ink spraying device of the present invention is provided with a substrate 26, a protective layer 27 formed on the substrate 26, and a protective layer 27 provided on the protective layer 27 to receive the ink 28. Solenoid coil located in the ink chamber 29, the nozzle plate 31 having a spacer 30 forming the ink chamber 29, a nozzle 32 for ejecting the ink 28 from the ink chamber 29, It consists of 33.

여기서 잉크챔버(29)는 도시되지 않은 통상의 잉크탱크와 연결되어 그로부터 공급되는 잉크로 채워진다. 솔레노이드코일(33)은 예를들면 리소그래피(lithography)와 박막기술을 이용한 박막코팅으로 되는 것으로서, 잉크탱크로부터 잉크챔버(29)로 공급되는 잉크(28)를 수용하는 중공부(부호생략)를 가지며, 그 양단부가 구동신호 발생기(34)와 연결되어 그 구동신호 발생기(34)로부터 인가되는 전기신호가 인가될 때 여자된다.Here, the ink chamber 29 is filled with ink supplied in connection with a conventional ink tank (not shown). The solenoid coil 33 is, for example, a thin film coating using lithography and thin film technology, and has a hollow portion (not shown) for receiving the ink 28 supplied from the ink tank to the ink chamber 29. Both ends thereof are connected to the drive signal generator 34 to be excited when an electric signal applied from the drive signal generator 34 is applied.

한편, 잉크(28)에는 금속 미립자 등의 자성물질(35)이 혼합되어 있다. 이 자성물질(35)은 솔레노이드코일(33)이 구동신호 발생기(34)의 전기신호에 의하여 여자될 때 그 솔레노이드코일(33)의 내부자계에 의하여 자화된다. 따라서 그 자성물질(35)에는 솔레노이드코일(33)의 전자적 추력이 작용하게 되고, 이 힘에 의하여 의하여 노즐(32)을 향하여 이동하게 된다. 이렇게 전자적 추력으로 이동하게 되는 자성물질(35)과 함께 잉크(28)가 이동하게 됨으로써 그 노즐(32)로부터 분사되는 토출잉크(36)가 만들어지는 것이다. 물론 토출잉크(36)는 상기한 자성물질(35)을 포함한다.In the ink 28, magnetic materials 35 such as metal fine particles are mixed. The magnetic material 35 is magnetized by the internal magnetic field of the solenoid coil 33 when the solenoid coil 33 is excited by the electrical signal of the drive signal generator 34. Therefore, the electronic thrust of the solenoid coil 33 acts on the magnetic material 35, and moves toward the nozzle 32 by this force. As the ink 28 moves together with the magnetic material 35 that is moved by the electronic thrust, the ejection ink 36 ejected from the nozzle 32 is made. Of course, the discharge ink 36 includes the magnetic material 35 described above.

본 발명에 따르면, 상기한 구동신호 발생기로부터 원하는 화상정보에 따라 변조된 전기신호(프린트 신호)를 발생하여 상기한 솔레노이드코일을 구동함으로써 원하는 문자나 화상을 프린트할 수 있다. 토출되는 잉크의 양은 상기한 구동신호 발생기에 의한 전기신호 주기와 관련된다. 즉, 그 전기신호가 인가되는 동안은 노즐로부터 잉크가 연속하여 토출되며, 전기신호를 인가함과 동시에 잉크가 토출되고 그 전기신호를 차단하면 그 즉시 잉크토출이 중단되어 그 잉크토출 제어가 용이한 것이다. 특히 솔레노이드코일의 전자적 추력 작용은 주변온도 등에 영향을 받지 않으므로 그 잉크의 토출제어와 양을 정확히 제어할 수 있게 된다. 따라서 본 발명은 해상도를 높이고 인쇄속도를 향상시키는데 효과적이다.According to the present invention, a desired character or image can be printed by generating an electric signal (print signal) modulated according to desired image information from the drive signal generator and driving the solenoid coil. The amount of ink ejected is related to the electric signal cycle by the drive signal generator described above. That is, while the electric signal is applied, ink is continuously discharged from the nozzle. When the electric signal is applied and the ink is discharged and the electric signal is blocked, the ink discharge is immediately stopped and the ink discharge control is easy. will be. In particular, since the electronic thrust action of the solenoid coil is not affected by the ambient temperature, it is possible to precisely control the discharge control and the amount of the ink. Therefore, the present invention is effective in increasing the resolution and improving the printing speed.

본 발명을 실시함에 있어서, 상기한 솔레노이드코일은 리소그래피와 박막기술에 의한 박막코팅구조가 아닌 기존 에나멜 코팅 코일을 별도의 보빈에 감은 것을 부착하는 것도 가능하며, 또한 노즐에 직접 형성하는 것도 가능하다. 이와 같이 본 발명은 상기에 설명되고 도면으로 예시된 것에 의하여 한정되는 것은 아니며 다음에 기재되는 특허청구의 범위 내에서 더 많은 변형 및 그 변용예가 가능한 것임은 물론이다.In the practice of the present invention, the solenoid coil described above may be attached to a separate bobbin wound with an existing enamel coated coil, which is not a thin film coating structure by lithography and thin film technology, or may be formed directly on a nozzle. As such, the present invention is not limited to the above described and illustrated in the drawings, and of course, more modifications and variations thereof are possible within the scope of the following claims.
