Description

ＬＥＤ를 이용한 프린터용 경화장치{Curing device for printer using LED}[0001] The present invention relates to a curing device for a printer,

본 발명은 LED를 이용한 프린터용 경화장치에 관한 것으로, 더욱 상세하게는 LED를 집광하여 광에너지를 높이면서도 광조사영역에서 균질한 광에너지를 공급하여 출력물의 품질을 향상시킬 수 있는 LED를 이용한 프린터용 경화장치에 관한 것이다.
The present invention relates to a printer curing apparatus using an LED, and more particularly, to a printer employing an LED that can enhance the quality of an output by supplying light energy homogenized in a light irradiation area while increasing light energy by condensing the LED To a curing apparatus for use.

UV프린터는 UV잉크를 피출력물에 분사한 후, 자외선에 의해 경화시켜야만 피출력물에 정착이 가능하다. 따라서, UV프린터는 경화장치가 필요하다.The UV printer can be fixed to the printout only after the UV ink is cured by ultraviolet rays after jetting the ink onto the printout. Therefore, a UV printer requires a curing device.

종래에는 경화장치로써 UV램프를 이용한 장치가 주로 사용되었다. 그러나, UV램프를 이용한 경화장치는 발열량이 너무 커서 냉각장치가 반드시 요구되며, 부피가 커지는 단점이 있다. 또, UV램프는 전기가 공급되서 일정한 광도의 자외선을 낼 때까지 일정시간이 소요되므로, UV램프를 온오프하지 않고 별도의 셔터를 포함하여야 한다.Conventionally, a device using a UV lamp as a curing device has been mainly used. However, the curing apparatus using a UV lamp has a disadvantage in that the amount of heat generated is too large to require a cooling device, which leads to an increase in volume. In addition, the UV lamp must include a separate shutter without turning on and off the UV lamp, since it takes a certain period of time until the UV lamp emits a constant intensity of light after being supplied with electricity.

이를 극복하기 위해 UV-LED를 사용하는 경화장치가 개발되었으나, UV-LED의 광에너지가 작아서 복수의 UV-LED를 설치하고, 이로부터 조사되는 자외선을 집광하여 사용하고 있다.In order to overcome this problem, a curing apparatus using UV-LED has been developed. However, since the light energy of UV-LED is small, a plurality of UV-LEDs are installed and ultraviolet rays irradiated therefrom are condensed and used.

그러나, 자외선을 집광하게 되면 도 6에 도시된 바와 같이 렌즈의 중심부에서 광에너지가 집중되므로, 전체적으로 균질한 경화가 이루어지지 못하는 문제점이 있다.
However, when the ultraviolet rays are condensed, as shown in FIG. 6, since the light energy is concentrated at the center of the lens, uniform uniform curing can not be achieved.

상기의 문제점을 해결하기 위해 안출된 본 발명의 목적은, LED를 집광하여 광에너지를 높이면서도 광조사영역에서 균질한 광에너지를 공급하여 출력물의 품질을 향상시킬 수 있는 LED를 이용한 프린터용 경화장치를 제공하는 데에 있다.

In the drawings, the same reference numerals are used to designate the same or similar components, and the same reference numerals will be used to designate the same or similar components. Detailed descriptions of known functions and configurations are omitted.

본 발명은 이중초점렌즈(120)를 사용하여 도 7에 도시된 바와 같이 중심부의 광에너지 준위를 낮추어서 주변부와 에너지차를 적게 하는 것에 주요한 특징이 있다. 또, 프린터의 헤드(102)에 의해 조사되는 영역이 대략 직사각형이므로, 상기 이중초점렌즈(120)의 단면이 대략 사각형을 가지는 통상의 렌즈를 사용한다.The present invention is characterized in that the bifocal lens 120 is used to reduce the light energy level in the central portion as shown in FIG. 7 to reduce the energy difference between the peripheral portion and the peripheral portion. In addition, since the area irradiated by the head 102 of the printer is substantially rectangular, a normal lens having an approximately rectangular cross section of the bifocal lens 120 is used.

이러한 이중초점렌즈(120)는 상기 다중초점렌즈인 집광렌즈(70)는 단면에서 보았을 때, 입사광 중 에너지준위가 높은 중심부의 광에 대하여 그 초점거리를 멀게 하여 초점을 형성되고, 중심부 이외의 주변부의 광에 대하여는 초점거리를 종래와 유사한 정도의 초점길이를 가지도록 형성시킨다. 이를 위해, 도 3에 도시된 바와 같이 중심부(126)의 곡률(ρ2)이 주변부(128)의 곡률(ρ1)보다 작도록 한다.In this bifocal lens 120, the focusing lens 70, which is a multi-focal lens, forms a focal point with a focal length distant from the center of the incident light having a high energy level when viewed from a cross section, The focal length is formed to have a focal length similar to the conventional one. 3, the curvature rho 2 of the center portion 126 is made smaller than the curvature rho1 of the peripheral portion 128, as shown in Fig.

따라서, 입사광 중 중심부(126)는 도 4에 도시된 바와 같이 원초점에서 모이게 되고, 주변부(128)는 근초점에서 모이게 되어, 통상의 이중초점렌즈(120)에 의해 형성된 에너지 준위는 도 4의 아래쪽의 형상 또는 도 7과 같다.4, the peripheral portion 128 is gathered at the near focus, and the energy level formed by the normal bifocal lens 120 is shifted to the right side in FIG. 4 The shape of the lower part is the same as shown in Fig.

피출력물(10)의 위치는 초점거리 이내이므로, 상기 피출력물을 근초점과 상기 이중초점렌즈(120) 사이에 오도록 위치시킨다.Since the position of the output object 10 is within the focal distance, the object to be printed is positioned between the near focus and the bifocal lens 120. [

따라서, 중심부 이외의 광은 종래와 마찬가지로 에너지 준위를 형성하며, 중심부의 광은 종래보다 초점으로부터의 거리가 먼 위치에 피출력물이 존재하게 되므로, 집광정도가 떨어져 중심부의 에너지 준위가 저하하게 된다.Therefore, light other than the central portion forms an energy level in the same manner as in the prior art, and the light in the central portion exists at a position farther from the focal point than in the prior art.

또, 상기 이중초점렌즈(120)에 의해 집광되는 광의 면적을 정확하게 하여, 불필요한 부분으로 자외선이 조사되지 않도록 상기 이중초점렌즈(120)의 아래에 관통홀(124)을 가지는 마스크(122)를 추가설치하는 것이 바람직하다.A mask 122 having a through hole 124 below the bifocal lens 120 is added so that the area of the light focused by the bifocal lens 120 is precisely adjusted so that ultraviolet rays are not irradiated to unnecessary portions It is desirable to install it.

따라서, 이러한 이중초점렌즈(120)와 상기 마스크(122)를 포함하는 경화장치(104)는 도 2에 도시된 바와 같이, 하우징(110)의 내부에 복수의 LED(114)를 LED홀더(112)를 이용하여 설치하고, 상기 이중초점렌즈(120)를 상기 LED(114)의 하측에 위치시키며, 상기 이중초점렌즈(120)의 하측으로 상기 마스크(122)를 위치시킨다.2, the curing apparatus 104 including the bifocal lens 120 and the mask 122 includes a plurality of LEDs 114 in an interior of the housing 110 and an LED holder 112 The bifocal lens 120 is positioned below the LED 114 and the mask 122 is positioned below the bifocal lens 120.

그리고, 상기 LED(114)의 상측으로 상기 LED(114)에서 발생되는 열을 발산할 수 있는 냉각팬(116)을 추가로 설치할 수 있다.Further, a cooling fan 116, which can dissipate the heat generated from the LED 114, may be further provided above the LED 114.

이러한 경화장치(104,106)을 헤드(102) 주위에 배치하여 헤드부(100)를 구성하며, 상기 헤드부(100)는 레일(108)에 설치되서 원하는 위치로 이송가능하다.These curing apparatuses 104 and 106 are disposed around the head 102 to constitute the head unit 100. The head unit 100 is mounted on the rail 108 and is transportable to a desired position.

상기와 같이, 본 발명의 바람직한 실시예를 참조하여 설명하였지만 해당 기술 분야의 숙련된 당업자라면 하기의 특허청구범위에 기재된 본 발명의 사상 및 영역으로부터 벗어나지 않는 범위 내에서 본 발명을 다양하게 수정 및 변경시킬 수 있음을 이해할 수 있을 것이다.
