Zusammenfassung:The present invention relates to a method for safely replacing a welding tip of a welding robot, and more particularly to the method for safely replacing a welding tip of a welding robot, allowing a welding tip replacement work for multiple welding robots installed in a workshop to be performed safely, and also shortening the time required for replacing welding tips, thereby increasing the production efficiency of products. The present invention relates to the method for safely replacing a welding tip of a welding robot, comprising: a standby state setting step (S10) for transmitting a signal from a main control device (100) to a plurality of welding robots (200) arranged in the workshop to return to a work standby state; a welding gun opening step (S20) of allowing the welding tip installed on a shank of a welding gun and a holder to be spaced apart from each other when the plurality of welding robots are returned to the work standby state by the standby state setting step (S10); an emergency stop step (S30) of stopping operation by cutting off power applied to the plurality of welding robots in the main control device (100) when mutual separation of the welding tips installed on the shank and the holder is completed; a welding tip replacement completion step (S40) of receiving a replacement completion signal from the main control device (100) after replacing the welding tip installed in the shank and the holder; and a work resume standby step (S50) of applying power to the welding robot in response to the welding tip replacement completion signal input to the main control device (100) to be in the work standby state. 본 발명은 용접로봇의 용접팁 안전교체방법에 관한 것으로, 보다 상세하게는 작업장 내에 설치된 다수의 용접로봇에 대한 용접팁교체작업을 안전하게 수행할 수 있도록 함은 물론 용접팁 교체에 따른 시간을 단축시켜 제품의 생산효율성을 높일 수 있도록 하는 용접로봇의 용접팁 안전교체방법에 관한 것이다. 본 발명은 메인제어장치(100)에서 작업장 내에 배치된 다수의 용접로봇(200)에 신호를 송신하여 작업대기상태로 복귀할 수 있도록 하는 대기상태설정단계(S10); 상기 대기상태설정단계(S10)에 의해 다수의 용접로봇이 작업대기상태로 복귀하게되면 용접건의 샹크와 홀더에 설치된 용접팁이 상호 이격될 수 있도록 하는 용접건오픈단계(S20); 샹크와 홀더에 설치된 용접팁의 상호 이격이 완료되면 상기 메인제어장치(100)에서 다수의 용접로봇에 인가되는 전원을 차단하여 구동을 정지하는 비상정지단계(S30); 상기 샹크와 홀더에 설치된 용접팁의 교체 후, 상기 메인제어장치(100)에서 교체완료신호를 입력받는 용접팁교체완료단계(S40); 상기 메인제어장치(100)로 입력된 용접팁교체완료신호에 의해 상기 용접로봇에 전원을 인가하여 작업대기상태에 있도록 하는 작업재개대기단계(S50);를 포함하여 이루어지는 것을 특징으로 한다.
