Description
본 발명은 자동차의 용접라인 중 메인 벅 지그(Main Buck Jig)공정에서 자동차의 하부측 패널을 용접하는 장치로서 다관절 6축 로봇을 적용하여 용접범위를 확대하고 그 효과로 작업시간을 단축시키고 지그에 부착된 더미건 용접기를 제거하여 지그를 단순화시켰으며 또한 연속적인 작업으로 용접전극(Tip)이 마모시 자동 용접전극 절삭 장치를 설치할 수 있어 라인 운영시간을 극대화 할수 있는 자동차 용접라인의 차체 하부 용접장치에 관한 것이다.The present invention is an apparatus for welding the lower panel of the vehicle in the main buck jig process of the welding line of the vehicle by applying a multi-joint 6-axis robot to extend the welding range and shorten the working time by the effect and jig The jig was simplified by removing the dummy gun welder attached to the main body. Also, continuous welding allows the automatic welding electrode cutting device to be installed when the welding electrode is worn out. Relates to a device.
종래에 사용되고 있는 메인벅 지그 공정에서 차체의 하부측 용접장치는 제3도에 도시된 바와같이 직교로봇(21)(21')을 사용하여 차체의 하부패널을 용접할 때 직교로봇(21)(21')이 X,Y,Z 방향의 직교방식으로 이동하면서 용접하기 때문에 작업범위가 한정되어 메인벅 지그(22)의 상부에 차체의 하부 패널 용접점중에 직교로봇(21)(21')으로 용접이 불가능한 다수의 용접점 하단에 다수의 더미건 용접기(도시없음)를 장착시켜 직교로봇(21)(21')의 작업범위 외에 용접부위를 용접하고 있다.In the main buck jig process used in the related art, the lower side welding apparatus of the vehicle body uses the orthogonal robots 21 and 21 'to weld the lower panel of the vehicle body as shown in FIG. 21 ') is welded while moving in the orthogonal manner in the X, Y, and Z directions, so that the working range is limited to the orthogonal robot 21, 21' among the lower panel welding points of the vehicle body on the upper part of the main buck jig 22. A plurality of dummy gun welders (not shown) are mounted at the lower end of the plurality of welding spots that are impossible to weld, thereby welding the welding portion outside the working range of the orthogonal robots 21 and 21 '.
상기와 같은 장치는 차체의 하부패널 용접점 중에 간섭이 발생되지 않는 용접점은 직교로봇(21)(21')으로 용접이 가능하지만 간섭 발생부위는 지그상에 더미건 용접기를 일일이 장착시켜 용접하여야 하므로 지그의 구조가 복잡해지고 직교로봇(21)(21')의 용접전극이 마모되면 공간이 협소하여 수동으로 용접전극을 절삭작업하여야 하므로 전체 용접 작업을 중단시켜야 하는 단점이 있고 또한 작업시 발생되는 용접분진이 장비 및 부품에 삽입되어 수명이 단축되는 문제점이 있었다.Such a device can be welded by orthogonal robots 21 and 21 'where the interference does not occur among the lower panel welding points of the vehicle body, but the interference generating parts must be welded by mounting a dummy gun welder on the jig. Therefore, when the structure of the jig becomes complicated and the welding electrodes of the orthogonal robots 21 and 21 'are worn out, the welding space must be manually cut because of a small space, and thus the entire welding operation must be stopped. There was a problem that the weld dust is inserted into the equipment and parts to shorten the life.
따라서 본 발명은 상기한 종래의 문제점을 개선하기 위한 목적으로 창출된 것으로 메인 벅 지그에 부착된 더미건 용접기를 제거 삭제하여 지그를 단순화 시키고 용접작업의 작업시간을 단축시키고 용접전극의 마모시 자동 용접전극 절삭장치에 의해 자동으로 용접전극을 절삭할 수 있는 다관절 6축 로봇을 적용하여 용접영역을 확대하고 고장 빈도를 축소시킴으로 유지 보수 비용을 절감시킬 수 있는 차체의 하부 패널 용접장치를 제공하기 위한 것이다.Therefore, the present invention has been created for the purpose of improving the above-mentioned conventional problems. The dummy gun welder attached to the main buck jig is removed to simplify the jig, shorten the working time of the welding operation, and automatically weld when the welding electrode is worn. By applying an articulated six-axis robot that can automatically cut welding electrodes by an electrode cutting device, it is possible to provide a lower panel welding device for a vehicle body that can reduce maintenance costs by expanding the welding area and reducing the frequency of failures. will be.

제1도는 본 발명의 사용상태를 도시한 전체구조도로서 다관절 6축 로봇을 적용시켜 용접작업을 수행하는 것을 나타내었으며 제2도는 본 발명의 정면 구조도이다.1 is an overall structural diagram showing a state of use of the present invention showing the welding operation by applying the articulated six-axis robot, and FIG. 2 is a front structural diagram of the present invention.
차량의 용접라인에 탑재된 차량(C)의 좌, 우측에 구조물(1)(1')이 설치되고 그 상부에 차량(C)의 상부 패널 용접용 다관절 6축 로봇(2)(2')이 장착된 차량의 용접라인에 있어서 하부에 설치되는 메인 벅 지그(3)에 별도의 더미건 용접기의 부착없이 내측으로 다관절 6축 로봇(4)(4')을 설치하여서 된 구조이다.The structures (1) and (1 ') are installed on the left and right sides of the vehicle (C) mounted on the welding line of the vehicle, and on the upper part thereof, the articulated six-axis robot (2) (2') for welding the upper panel of the vehicle (C). ) Is a structure in which the articulated six-axis robot (4) (4 ') is installed in the main buck jig (3) installed in the lower part in the welding line of the vehicle is installed without an additional dummy gun welder.
이와같이 된 본 발명은 차량(C)의 하부 패널을 용접함에 있어 메인 벅 지그(3)의 내측으로 설치된 다관절 6축 로봇(4)(4')의 6개의 관절을 활용하므로 간섭부위를 피해서 자유롭게 동작하여 하부 패널의 용접 포인트를 전체적으로 수용이 가능하여 별도로 메인 벅 지그(3)에 더미건 용접기를 부착하여 로봇의 용접영역 밖의 용접포인트를 용접할 필요가 없어 메인 벅 지그(3)의 구조를 단순화 시키고 다관절 6축 로봇(4)(4')을 적용함으로 용접전극의 마모시 로봇의 선단에 장착된 용접전극을 자유롭게 동작시켜 로봇의 일측에 착설된 용접 전극 자동 절삭 장치로 동작시켜 자동 절삭할 수 있게하여 조립라인의 연속적인 작업 수행을 가능케 하였다.In the present invention, the six joints of the articulated six-axis robot (4) (4 ') installed inside the main buck jig (3) are used to weld the lower panel of the vehicle (C). It is possible to accommodate the welding points of the lower panel as a whole, so that a dummy gun welder is separately attached to the main buck jig 3 so that the welding point outside the welding area of the robot is not welded, thereby simplifying the structure of the main buck jig 3. By applying multi-joint 6-axis robot (4) (4 '), the welding electrode mounted on the tip of the robot can be freely operated when the welding electrode wears out, and it can be operated automatically by the welding electrode automatic cutting device installed on one side of the robot. This enables the continuous operation of the assembly line.
그러므로 본 발명은 다관절 6축 로봇을 적용시킴으로 6개의 관절을 동작시켜 용접범위가 확대되어 메인 벅 지그에 부착되던 더미건 용접기를 삭제할 수 있어 지그를 단순화시킬수 있을 뿐만아니라 경제적인 효과와 유지보수에 따른 불편함을 해결할수 있으며 용접 전극의 절삭장치도 자동으로 수행되어 용접작업의 연속성이 유지되어 작업능률을 항상시키고 전체적인 용접라인의 작업시간을 단축시킬수 있는 효과가 있는 발명인 것이다.Therefore, the present invention can be applied to the articulated six-axis robot to operate the six joints to increase the welding range can be deleted the dummy gun welder attached to the main buck jig can not only simplify the jig but also economical effect and maintenance According to the present invention, it is possible to solve the inconvenience, and the cutting device of the welding electrode is automatically performed to maintain the continuity of the welding operation, thereby improving the work efficiency and reducing the overall welding line working time.
