레이저(Laser)는 Light Amplification by Stimulated Emission of Radiation 의 첫 머리 글자를 딴 단어로 복사의 유도방출에 의한 빛의 증폭현상이라는 의미를 갖는다. The term "laser" refers to the first word of Light Amplification by Stimulated Emission of Radiation, which means the amplification of light by stimulated emission of radiation.

상기 레이저는 단색광, 평행광, 직진성, 가간섭성을 갖는 품질이 매우 높은 빛 에너지로서 집광하기 쉬운 특성을 가지므로 높은 에너지 밀도를 가질 수 있어서, 이를 이용하면 고밀도의 열원으로 용접을 비롯한 다양한 재료 가공에 사용이 가능하다.The laser has high energy density because it has characteristics of monochromatic light, parallel light, direct light, highly coherent light with high quality and can be condensed, so that it can be used as a high-density heat source Can be used.

It is widely used in many industrial fields.

상기 레이저를 이용한 용접은 자생용접으로 용접선을 정확하게 따라서 용접하는 것이 중요한데, 이렇게 용접선을 정확히 따라서 용접하기 위해서 용접헤드가 정확하게 움직이는 것 이외에도 피용접물의 위치교정과 이를 모니터링하면서 용접하는 기술이 중요하다. It is important to precisely weld the weld line by self-welding. In addition to precisely moving the welding head in order to precisely weld the weld line, it is important to correct the position of the weld and monitor the welding.

상기 레이저용접헤드가 용접하는 용접부위를 직접적으로 관찰할 수 있도록 하기 위해서 여러가지 모니터링 수단이 제공되는데, 통상의 모니터링 기술은 적외선(IR), 자외선(UV), 가시광선을 이용한 카메라를 사용하거나, 음성 및 변환 음향과 같은 센서들을 이용한 카메라를 사용한다.Various monitoring means are provided in order to be able to directly observe the welding spot welded by the laser welding head. The usual monitoring technique is to use a camera using infrared (IR), ultraviolet (UV) And a camera using sensors such as conversion sound.

종래의 레이저용접의 모니터링 방법에 관한 기술은 대한민국 특허청 등록특허공보 제1007724호 및 제1405267호 등에 개시된 바 있다.Techniques relating to a conventional monitoring method of laser welding have been disclosed in Korean Patent Registration No. 1007724 and No. 1405267, for example.

상기 콜리메이션렌즈부의 측면에는 밀러를 통해서 조사부를 확인할 수 있는 카메라가 부착되고, 조사부와 이격되도록 조명(3)이 형성되며, A camera is attached to a side surface of the collimation lens unit through a mirror to confirm the irradiation unit. An illumination unit 3 is formed so as to be separated from the irradiation unit,

상기 카메라의 영상을 받아들여서 영상을 확인할 수 있도록 컴퓨터와 모니터가 전체장치의 측면에 설치되어 형성된다. A computer and a monitor are installed on the side of the entire apparatus so as to receive the image of the camera and confirm the image.

그러나, 종래의 레이저용접의 모니터링 방법은 다음과 같은 문제점이 있었다.However, the conventional laser welding monitoring method has the following problems.

(1) 레이저장치 전체에 컴퓨터와 모니터(3)가 별도로 부착되어 있어야 하므로 장치전체의 크기가 커진다. (1) Since the computer and the monitor 3 are separately attached to the entire laser device, the size of the whole device becomes large.

(2) 레이저용접헤드에 조명을 위한 전선, 카메라데이터를 송출하는 선 등 다양한 선들이 부착되어 있어서 레이저용접헤드를 자유롭게 움직이는데 방해를 주게 된다.(2) Various wires are attached to the laser welding head, such as a wire for lighting and a wire for sending camera data, which interferes with the free movement of the laser welding head.

(3) 최초 용접부위를 정확히 맞추어서 용접을 시작하지만, 용접을 시작하고 용접을 하는 동안에는 레이저의 높은 광량으로 인해서 카메라가 영상을 송출하지 못하고 화이트가 지속되어 모니터링할 수 없다.(3) The welding is started with the first welding point correctly. However, during welding and welding, the camera can not transmit the image due to the high light intensity of the laser, and the white can not be continuously monitored.

상기한 문제점을 해결하기 위해서, 본 발명은 상부에 장치에서 생성되는 빛이 조사되는 파이프가 연결되는 콜리메이션렌즈부와; 상기 콜리메션렌즈부의 하단에 부착되는 포커스렌즈부와; 상기 포커스렌즈부의 하단에 형성되는 조사부로 구성되는 일반적인 레이저용접헤드에 있어서, In order to solve the above-mentioned problems, the present invention provides an image forming apparatus including a collimation lens unit to which a pipe irradiated with light generated in an apparatus is connected; A focus lens unit attached to a lower end of the collimation lens unit; And an irradiation part formed at a lower end of the focus lens part,

상기 조사부의 내부에는 조명이 내장되는 것을 특징으로 한다.And the illumination unit is embedded in the irradiation unit.

본 발명의 바람직한 실시예로 용접부 모니터장치 일체형 레이저용접헤드에 의하면 다음과 같은 효과가 발생한다.According to a preferred embodiment of the present invention, the following effects are produced by the laser welding head integrated with the welding part monitor device.

(1) 처리장치와 모니터가 레이저용접헤드에 직접부착되어 있어서 장치 전체의 크기가 작아져서 공간효율이 좋다.(1) Since the processing apparatus and the monitor are directly attached to the laser welding head, the overall size of the apparatus is reduced and the space efficiency is good.

(2) 레이저용접헤드에 부착되는 다수의 선들이 제거되어 레이저용접헤드의 움직임에 전혀 방해를 주지 않는다.(2) a plurality of lines attached to the laser welding head are removed so as not to disturb the movement of the laser welding head at all.

(3) 포커스렌즈부의 내부에 형성되는 조명이 레이저용접시 발생되는 빛의 주파수와 유사한 영역대의 화이트 조명을 사용하기 때문에 카메라가 용접부위를 계속 촬상할 수 있어서 용접중에도 계속하여 모니터링할 수 있어서 정확한 용접을 수행할 수 있다.(3) Since the illumination formed inside the focus lens unit uses the white light of the area similar to the frequency of the light generated in the laser welding, the camera can continue to image the welding part so that it can be continuously monitored during welding, Can be performed.

The focus lens section 20 at the lower end of the collimation lens section 30 is a section that focuses the laser light to be irradiated with the parallel light and does not need to completely match the focal point. However, in order to set the intensity, .

상기 처리장치(110)는 카메라모듈을 탑제하고, 조명을 컨트롤하며, 모니터장치(120)에 영상을 처리하여 송출하는 장치이다. The processing device 110 is a device for installing a camera module, controlling lighting, processing images to the monitor device 120, and transmitting the images.

상기 처리장치(110)는 카메라(40)의 상단에 부착될 수 있는데, 처리장치(110)는 모니터와 기계적으로 연결된다. The processing unit 110 may be attached to the top of the camera 40, which is mechanically coupled to the monitor.

상기 포커스렌즈부(20)의 처리장치(110), 카메라(40)는 일체로 형성되고, 모니터장치(120)도 콜리메이션렌즈부(30)의 전면에 일체로 형성되는데, 모니터장치(120)는 화면의 방향을 바꿀 수 있도록 링크장치로 형성될 수 있다.The monitor 110 and the camera 40 of the focus lens unit 20 are integrally formed and the monitor 120 is integrally formed on the entire surface of the collimation lens unit 30. The monitor unit 120, May be formed as a link device so as to change the direction of the screen.

상기 조명(130)은 조사부(10)의 내부에 형성되는데, 800~900MHz 대역의 화이트광을 조사할 수 있도록 형성된다.The illumination unit 130 is formed inside the irradiation unit 10 and is configured to emit white light in the 800 to 900 MHz band.

상기 카메라(40)에는 라인제너레이터가 형성되어 십자선이 조사되는데, 이는 피용접물(1)의 용접부위를 정확히 맞출 수 있도록 형성된다.A line generator is formed in the camera 40 so that a reticle is irradiated, which is formed so as to precisely match a welding portion of the workpiece 1 to be welded.

상기 조명(130)은 포커스렌즈부(20)의 내부에 포함될 수 있다.The illumination 130 may be included inside the focus lens unit 20.

본 발명에서 설명된 측면, 상단 등은 레이저용접헤드로 파이프(5)상단에 수직하게 연결될 때를 기준으로 한 것이고, 파이프(5)가 90도 또는 임의의 각도로 조사되도록 형성된다면 거기에 맞추서 다양하게 설치될 수 있다.The side, top, etc. described in the present invention are based on being vertically connected to the upper end of the pipe 5 with a laser welding head, and if the pipe 5 is formed to be irradiated at 90 degrees or an arbitrary angle, It can be installed variously.

이하, 본 발명의 바람직한 실시예로 형성된 용접부 모니터장치 일체형 레이저용접헤드의 작동을 설명하면 다음과 같다.Hereinafter, the operation of the laser welding head integrated with a welded part monitoring apparatus formed as a preferred embodiment of the present invention will be described.

레이저장치에 레이저용접헤드를 장착하고, 이송바에 레이저용접헤드를 설치한다. A laser welding head is mounted on the laser device, and a laser welding head is mounted on the transfer bar.

상기 레이저용접헤드를 설치하고, 파이프(5)를 상단에 연결한 후에 전원을 연결하면 조명(130)이 켜지고, 모니터장치(120)에 영상이 비춰진다. When the power source is connected after the laser welding head is installed and the pipe 5 is connected to the upper end, the illumination 130 is turned on and the image is displayed on the monitor device 120.

이때, 피용접물(1)을 조사부(10)의 하단에 놓고, 카메라(40)에서 조사되는 십자선을 모니터장치(120)로 확인하면서 피용접물(1)의 용접부위를 정확하게 맞춰서 고정한다. At this time, the workpiece 1 is placed on the lower end of the irradiating unit 10, and the welded portion of the workpiece 1 is precisely adjusted while fixing the reticle irradiated by the camera 40 to the monitor device 120.

이후, 레이저용접을 시작하면 용접시 플라즈마가 발생하지만, 조명이 플라즈마와 비슷한 영역대의 빛이어서 카메라(40)가 이를 감지하여 콘크라스트 등을 자동으로 조절함으로써 용접부위를 계속하여 촬상할 수 있다.Then, when the laser welding is started, plasma is generated at the time of welding. However, since the illumination is the light of the region similar to the plasma, the camera 40 senses it and automatically adjusts the con-

레이저용접헤드에 조명장치가 내부로 들어가 있기 때문에 레이저용접헤드의 자세를 자유롭게 회전할 수 있어서 용접범위가 넓어진다.Since the illumination device is located inside the laser welding head, the attitude of the laser welding head can be freely rotated and the welding range is widened.

본 발명의 바람직한 실시예로 용접부 모니터장치 일체형 레이저용접헤드에 의하면 처리장치와 모니터가 레이저용접헤드에 직접부착되어 있어서 장치 전체의 크기가 작아져서 공간효율이 좋고, 레이저용접헤드에 부착되는 다수의 선들이 제거되어 레이저용접헤드의 움직임에 전혀 방해를 주지 않으며, 포커스렌즈부의 내부에 형성되는 조명이 레이저용접시 발생되는 빛의 주파수와 유사한 영역대의 화이트조명을 사용하기 때문에 카메라가 용접부위를 계속 촬상할 수 있어서 용접중에도 계속하여 모니터링할 수 있어서 정확한 용접을 수행할 수 있는 등의 효과가 발생한다.According to a preferred embodiment of the present invention, the laser welding head integrated with the monitor unit of the present invention has a processing apparatus and a monitor directly attached to the laser welding head, thereby reducing the overall size of the laser welding head. So that the illumination formed inside the focus lens unit uses the white light of the area band similar to the frequency of the light generated when the laser welding is performed so that the camera continues to pick up the welding spot So that the welding can be continuously performed even during welding so that accurate welding can be performed.

본 발명은 첨부된 도면을 참조하여 바람직한 실시 예를 중심으로 기술되었지만 당업자라면 이러한 기재로부터 후술하는 특허청구범위에 의해 포괄되는 본 발명의 범주를 벗어남이 없이 다양한 변형이 가능하다는 것은 명백하다.While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art without departing from the scope of the invention as defined by the appended claims.
