Description

냉각지그가 구비된 레이져 브레이징 장치{LASER BRAZING DEVICE HAVING COOLING JIG}Laser Brazing System with Cooling Jig {LASER BRAZING DEVICE HAVING COOLING JIG}

본 발명은 브레이징 장치에 관한 것으로, 보다 상세하게는 레이저 브레이징시에 냉각지그를 구비하여 브레이징에 따른 변형을 방지할 수 있는 냉각지그가 구비된 레이져 브레이징 장치에 관한 것이다.The present invention relates to a brazing device, and more particularly, to a laser brazing device having a cooling jig provided with a cooling jig at the time of laser brazing to prevent deformation due to brazing.

일반적으로 레이져 브레이징은 레이져 열원에 의해 용융된 삽입금속(예:필러와이어)이 모재표면에 젖은후 모세관 현상에 의해 유입됨에 의해서 접합되는 공법을 말한다.In general, laser brazing refers to a method in which an insertion metal (eg, filler wire) melted by a laser heat source is joined to the base metal surface by wet and introduced by capillary action.

이러한 레이저 브레이징 공법은 브레이징 되는 패널과 레이저 초점 및 공급되는 필러 와이어의 끝단이 일치되어야 양호한 브레이징부를 얻을 수 있다.In this laser brazing method, a good brazing part can be obtained only when the end of the panel to be brazed and the laser focus and the filler wire to be fed are matched.

그러나, 상기 브레이징은 연속적으로 진행되기 때문에 저입열의 레이저 열원이라 할지라도 패널의 변형이 쉽게 발생되어 용접불량이 발생되는 문제점이 있다. 이에 따라 패널의 변형을 제거하기 위한 방법으로서 레이저 브레이징 공법에 맞는 냉각시스템이 필요하다.However, since the brazing proceeds continuously, even in the case of a low heat input laser heat source, the panel is easily deformed, resulting in a poor welding. Accordingly, a cooling system suitable for the laser brazing method is required as a method for removing the deformation of the panel.

본 발명은 상기 전술한 바와 같은 문제점들을 해결하기 위해 창출된 것으로서, 레이저 브레이징시에 냉각지그를 구비하여 용접에 따른 변형을 방지할 수 있는 냉각지그가 구비된 레이져 브레이징 장치를 제공하는데 그 목적이 있다.SUMMARY OF THE INVENTION The present invention has been made to solve the problems described above, and an object thereof is to provide a laser brazing device having a cooling jig, which is provided with a cooling jig at laser brazing and prevents deformation due to welding. .
