용접로봇용 토치 클리닝장치{TOARCH CLEANING DEVICE OF A WELDING ROBOT}Torch Cleaning Device for Welding Robots {TOARCH CLEANING DEVICE OF A WELDING ROBOT}

본 발명은 용접로봇용 토치 클리닝장치에 관한 것으로, 더욱 상세하게는 간단한 구조로 형성되어 고장시 유지보수가 용이하며, 토치에 발생된 불순물을 효과적으로 제거할 수 있도록 한 용접로봇용 토치 클리닝장치에 관한 것이다.The present invention relates to a torch cleaning apparatus for a welding robot, and more particularly, to a torch cleaning apparatus for a welding robot, which is formed in a simple structure to facilitate maintenance in case of failure and to effectively remove impurities generated in the torch. will be.

일반적으로 용접로봇에 사용되는 용접토치는 용접철선이 토치를 통하여 연속적으로 공급되게 하여 용접할 수 있도록 구성하였던바, 1회 용접 공정이 종료되었을 때에는 토치의 선단에 끼인 불순 산화물을 제거해 주어야만 다음 용접이 정확하게 이행되는 것이다.In general, the welding torch used in the welding robot is configured to allow welding wire to be continuously supplied through the torch. When the welding process is finished, the impurity oxide trapped at the tip of the torch must be removed. It is done correctly.

즉, 용접로봇에 의해 계속적인 용접작업이 수행되게 되면, 토치의 선단에 다량의 스패터(spatter) 및 이물질이 부착되어 지고, 이로 인해 다음 용접시 부정확하게 용접되어 불량률이 높아짐에 따라 1회 용접후에는 토치의 선단에 끼인 불순물을 제거한 후 사용하고 있다.That is, when continuous welding work is performed by the welding robot, a large amount of spatters and foreign substances are attached to the tip of the torch, which causes incorrect welding during the next welding, thereby increasing the defective rate. Afterwards, it is used after removing impurities stuck to the tip of the torch.

상기한 불순물의 제거시에는 작업자가 직접 청소하거나 혹은 자동으로 토치를 클리닝하는 장치를 이용하여 불순물을 제거하고 있다.When the impurities are removed, the worker removes the impurities using a device for cleaning the torch or cleaning the torch automatically.

자동으로 토치를 클리닝 하는 장치, 즉 토치클리너는 도 1과 같이 대한민국 실용신안공보 제1995-0001935호에 개시되어 있다.An apparatus for automatically cleaning the torch, that is, a torch cleaner is disclosed in Korean Utility Model Publication No. 1995-001001 as shown in FIG.

그러나 상기한 종래의 토치클리너는 그 구조가 복잡하여 제품생산시 생산비용의 증가를 가져오며, 고장률이 높아 유지보수비용 및 인건비의 증가를 가져오는 단점이 있었다.However, the conventional torch cleaner has a disadvantage in that its structure is complicated, leading to an increase in production cost when producing a product, and an increase in maintenance cost and labor cost due to high failure rate.

또한, 토치로부터 떼어낸 스패터가 원활하게 외부로 배출되지 못하고, 로터리크리너(3)의 내측으로 구비되어 짐으로써 스패터의 제거가 용이하지 않을 뿐만 아니라 이 과정에서 재차 스패터가 고착되면서 완벽한 스패터의 제거가 불가능하여 결국 양호한 용접효과를 기대하기가 어려웠던 문제점이 있었으며, 특히 유압실린더를 이용하고 있음에 따라 승강판(4)의 동작시 과도한 압력이 작용하게 되어 부하로 인한 파손우려가 있을 뿐만 아니라 로터리크리너(3)의 회전시 너무 낮은 회전력을 제공함에 따라 토치클리너에 적용하여 사용하기에는 적합하지 않은 문제점이 있었다.In addition, the spatter removed from the torch is not discharged to the outside smoothly, and the inside of the rotary cleaner 3 is not easy to remove the spatter, and in this process, the spatter is stuck again and the perfect spatter There was a problem that it was impossible to remove the rotor, so it was difficult to expect a good welding effect, and in particular, since the hydraulic cylinder is used, excessive pressure was applied during the operation of the lifting plate 4, which may cause damage due to the load. However, there was a problem that is not suitable for use in the torch cleaner as it provides too low rotational force during rotation of the rotary cleaner (3).
