Abstract

본 발명은 자동차용 박판의 맞대기 레이져용접 모니터링 장치에 관한 것으로, 종래에는 용접 상태를 살펴보기 위해 펀치와 같은 도구를 이용하여 용접된 박판을 미는 작업을 할 때 크랙이 발생되는 문제가 발생하기도 했다.The present invention relates to a buttress laser welding monitoring apparatus for an automotive thin plate, and in the related art, there is a problem that a crack is generated when a welded thin plate is pushed using a tool such as a punch to examine a welding condition.

따라서 본 발명에서는, 각 요소 부위별로 최적의 강도, 두께, 재질을 미리 세팅하여 된 제어용 컴퓨터와; 라인 작업시 상기 박판을 컨베이어 벨트에 상치시킨 후 서로 맞대기 용접으로 일체 성형시키는 고출력 탄소레이져와; 상기 제어용 컴퓨터의 신호에 따라 용접 부위에 붉은색의 광선을 조사시키면서 파라볼릭 렌즈에 의해 조절되게 한 저출력 헬륨·네온의 모니터링용 레이져와; 상기 광선을 포착한 다음 상기 어용 컴퓨터에 그 신호를 전송시켜 용접상태와 크랙여부를 판단하는 카메라로 구성된 것으로, 제품에 크랙이 발생하는 등의 문제를 예방할 수 있게 된 발명다.Therefore, in the present invention, a control computer having optimum strength, thickness, and material set in advance for each element part; A high-output carbon laser for placing the thin plate on a conveyor belt during line work, and integrally forming the thin plate on the conveyor belt by butt welding; A low power helium / neon monitoring laser controlled by a parabolic lens while irradiating a red light beam at a welding site according to a signal of the control computer; And a camera for capturing the light beam and transmitting the signal to the computer for determining the welding state and the cracking state, thereby preventing a problem such as cracking of the product.
