Zusammenfassung: | The present invention relates to a welding robot including a flexible joint unit, which comprises: a torch unit for welding an object; a joint unit having one side thereof connected to the torch unit and a plurality of link joint units coupled and connected to each other through a fixing pin, wherein each of the link joint units is swung at an angle set with respect to the fixing pin to change a curvature; a tension control belt disposed on a side surface of the joint unit to be moved in one direction or the other direction so as to apply controlled tension to the joint unit; and a curvature change rotation unit having the outer surface thereof formed to be in contact with the tension control belt at the other side of the joint unit to move the tension control belt in one direction or the other direction through rotation, and controlling the tension applied to the joint unit to change the curvature of the joint unit. According to the present invention, the welding may be performed without colliding with a wall or the like even in a narrow space.
대상체의 용접을 수행하는 토치부; 일측이 상기 토치부와 연결되고, 복수개의 링크관절부가 고정핀을 통하여 결합 연결되어서 각각의 링크관절부가 상기 고정핀을 기준으로 설정된 각도로 스윙되어 곡률이 변경될 수 있는 관절부; 상기 관절부의 측면에 배치되어 일방향 또는 타방향 이동되어 상기 관절부에 장력을 조절된 장력을 가하는 장력조절밸트; 및 상기 관절부의 타측에서 상기 장력조절밸트와 외측면이 맞닿도록 형성되어서 회전을 통하여 상기 장력조절밸트를 일방향 또는 타방향으로 이동시켜 상기 관절부에 가해지는 장력을 제어하여 상기 관절부의 곡률을 변경하는 곡률변경회전부 를 포함하는 플렉시블 관절부를 포함하는 용접로봇이 개시된다. |
