Gas welding automation system {Gas welding automation system}

본 발명은 가스용접 자동화시스템에 관련되며, 보다 상세하게는 회전테이블에 설치되는 회전지그의 공전 및 자전운동에 의해 피용접물 투입단계, 황동링로딩단계, 예열단계, 용매링로딩단계, 가스용접단계, 냉각단계, 피용접물 배출단계를 연속적으로 수행하도록 구조 개선되어, 가스용접의 자동화를 도모하므로 인건비 절감과 더불어 용접품질 균일화 및 생산성 향상을 도모할 수 있는 가스용접 자동화시스템에 관한 것이다.The present invention relates to a gas welding automation system, and more specifically, a welding material input step, a brass ring loading step, a preheating step, a solvent ring loading step, and a gas welding step by the revolution and rotation motion of a rotary jig installed on a rotary table. The present invention relates to a gas welding automation system that can reduce labor costs, uniformize welding quality, and improve productivity by improving the structure to continuously perform a cooling step and a discharge step of a welded object, thereby automating gas welding.

통상 용접장치는 동종 내지 이종의 금속재질의 접합면을 가열 및 용융하여 상호 접합하기 위한 장치로서, 가스식, 레이저식 내지 아크식 용접작업구를 포함하여 이루어진다.Conventional welding devices are devices for heating and melting bonding surfaces of the same or different types of metal materials to mutually join them, and include gas-type, laser-type, or arc-type welding tools.

그리고, 원형 관체를 용접하는 경우, 작업자가 원주방향을 따라 용접기를 이동시키는 방식의 수작업에 의해 진행되었으며, 원주형 곡면부의 용접을 수행하는 과정에서 작업자의 피로도가 증가할 뿐만 아니라, 용접작업의 정확도를 보장하기 어렵고, 이에 회전식 턴테이블 등의 상면에 용접대상물을 배치하고 회전시키면서 용접하는 장치로서 개선이 이루어져 왔으나, 턴테이블에 용접대상물을 배치하는 과정에서 발생되는 용접위치의 오차로 인해 용접불량이 빈번히 발생된다.In addition, in the case of welding a circular tubular body, it is carried out manually by moving the welder along the circumferential direction, and not only increases the fatigue of the worker in the process of welding the cylindrical curved surface, but also increases the accuracy of the welding work. It is difficult to guarantee, and therefore, improvements have been made as a device that welds while placing and rotating an object to be welded on the upper surface of a rotary turntable, etc., but welding defects frequently occur due to errors in the welding position generated in the process of arranging the object to be welded on the turntable. do.

일예로서, 냉장고 또는 에어컨 등과 같은 냉동기기에는 열을 흡열 또는 방열이 이루어지는 증발기와 응축기 등과 같은 열교환기에는 열교환의 효율성을 높이기 위하여 그 재료를 열전도율이 높은 알루미늄을 사용하고 있으며, 콤프레셔와의 사이에서 냉매가 순환되는 관로는 그 강도와 배관의 용이성을 위하여 구리관을 냉매관으로 사용되는바, 이러한 이종 간 용접은 대부분 그 양측에서 열을 가해 용접을 수행하고 있지만, 둘레에 균일한 열을 가하지 못하여 부분적인 용접 불량이 나타나게 되는 등 제품의 품질이 저하되는 실정이다.As an example, in refrigeration devices such as refrigerators or air conditioners, heat exchangers such as evaporators and condensers that absorb or dissipate heat use aluminum with high thermal conductivity to increase the efficiency of heat exchange, and a refrigerant between the compressor and the compressor. Copper pipes are used as refrigerant pipes for the strength and ease of piping. In most of these heterogeneous welding, welding is performed by applying heat from both sides, but partial The quality of the product is degraded, such as the appearance of welding defects.

이에 종래에 개시된 등록특허 10-1807867호에서, 하부 중앙에 설치되는 감속모터 구동에 의해 회전하는 턴테이블; 턴테이블에 둘레 근접부에 일정한 간격을 두고 원주 방향으로 다수 형성되어 용접하고자 하는 이종관 제품이 장착되며 턴테이블로부터 자유 회전력을 가지는 이종관 장착부; 턴테이블의 하부에 형성되어 이웃하는 2개의 이종관 장착부에 자전력을 부여하는 자전 구동부; 및 턴테이블과 분리 형성되어 자전되는 2개의 이종관 장착부에 불꽃을 부여하여 이종관을 용접하고자 하는 용접링을 용용 및 이종관을 용접하는 용융 용접부를 포함하는 기술이 선 제시된 바 있다.Accordingly, in the conventionally disclosed Patent Registration No. 10-1807867, a turntable rotating by driving a reduction motor installed in the lower center; A heterogeneous pipe mounting part formed on the turntable in a circumferential direction at regular intervals at a circumferential portion, mounted with heterogeneous pipe products to be welded, and having free rotational force from the turntable; A rotation drive unit formed at the bottom of the turntable to apply magnetic force to two adjacent heterogeneous tube mounting units; and a technology including a melting welding part for welding a welding ring to be welded and welding a different type of pipe by applying sparks to two different type of pipe mounting parts that are formed separately from the turntable and rotating themselves has been previously suggested.

그러나, 상기 종래기술은 관의 둘레에 대해 균일한 용접이 가능하게 하면서 작업능률을 향상시키려는 것이나, 팽창밸브에서 분사된 액/증기를 균질의 혼합체로 만들어 복수의 모세관으로 균등하게 분배하는 디스트리뷰터모듈을 용접시, 토치를 이용하여 어느 하나의 모세관을 용접시 주변 모세관과 토치 간에 간섭으로 인해 디스트리뷰터모듈 회전 작동에 방해가 되고, 이로 인해 모세관이 토치 열에 균일하게 가해지지 않아 전체적인 용융점을 파악해야 하는 등 전문가가 아니면 용접이 힘든 문제점이 따랐다.However, the prior art is to improve work efficiency while enabling uniform welding on the circumference of the tube, but a distributor module that equally distributes the liquid / steam injected from the expansion valve into a homogeneous mixture to a plurality of capillaries When welding one capillary tube using a torch, interference between the surrounding capillaries and the torch interferes with the rotation of the distributor module. Otherwise, welding was difficult.
