본 발명은 수직다관절 로보트에 관한 것으로서, 특히 소형, 경량화된 구조로, 작업 범위가 넓으며, 동역학적 특성 및 안정성이 향상되도록 개선된 수직다관절 로보트에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vertical articulated robot, and more particularly, to a vertical, articulated robot with a small, light weight structure, a wide working range, and improved dynamic characteristics and stability.

종래의 수직다관절 로보트는 제1도 및 제2도에 개략적으로 도시되어 있는 바와같이, 레일(5)을 따라 이동되는 베이스부(1)의 선단 하부에 4절링크 방식의 어깨부(2)가 회동가능하게 설치되고, 이 어깨부(2)의 선단에는 아암부(3)가 회동가능하게 설치되며, 아암부(3)의 선단에는 손목부(4)가 회동가능하게 설치되어 있다.The conventional vertical articulated robot has a four-link link shoulder portion 2 at the lower end of the base portion 1 moved along the rail 5, as schematically shown in FIGS. 1 and 2. Is rotatably provided, and an arm portion 3 is rotatably installed at the tip of the shoulder portion 2, and a wrist portion 4 is rotatably provided at the tip of the arm portion 3.

그리고 베이스부(1)에 설치된 제1모터(6)에 의해 어깨부(2)가 회동되고, 어깨부(2) 하단의 양측에 각각 설치된 제2, 제3모터(7)(8)에 의해 링크(9)(10)가 상하로 이동되면서 아암부(3)를 상하로 회동시키도록 되어 있다.And the shoulder part 2 is rotated by the 1st motor 6 provided in the base part 1, and the 2nd and 3rd motors 7 and 8 provided in the both sides of the lower end of the shoulder part 2, respectively, are carried out. As the link 9 and 10 are moved up and down, the arm part 3 is rotated up and down.

그리고 아암부(3)의 후단에 설치된 제4모터(11)에 의해 아암부(3)가 자체 회동되면서 손목부(4)를 회전시키도록 되어 있으며, 아암부(3)의 선단에 설치된 제5모터(12)에 의해 손목부(4)가 상하로 회동하고 제6모터(13)에 의해 손목부 선단이 회전되도록 되어 있다.In addition, the arm part 3 rotates itself by the fourth motor 11 installed at the rear end of the arm part 3, thereby rotating the wrist part 4, and the fifth part installed at the tip of the arm part 3. The wrist part 4 is rotated up and down by the motor 12, and the tip part of the wrist part is rotated by the 6th motor 13. As shown in FIG.

그러나 이와같이 구성된 종래 수직다관절 로보트는 다음과 같은 문제점을 가지고 있다.However, the conventional vertical articulated robot configured as described above has the following problems.

첫째, 어깨부가 4절링크 방식으로 구성되어 있으므로 구조가 복잡하고, 로보트 중량이 무거워지는 문제점이 있었다.First, since the shoulder part is configured in a four-section link method, there is a problem that the structure is complicated, the robot weight is heavy.

둘째, 손목부를 구동시키기 위한 모터가 아암부의 선단에 설치되어 있고, 어깨부가 베이스부의 하부에 설치되어 있으므로, 로보트의 질량중심이 베이스부로부터 멀게 됨에 따라 어깨부와 베이스에 하중이 많이 걸리게 되어 로보트의 동역학적 특성 및 안정성이 떨어지고, 이로인해 어깨부 모터와 베이스부 모터의 용량을 크게 하여야 하는 문제점이 있었다.Second, since the motor for driving the wrist part is installed at the tip of the arm part and the shoulder part is installed at the lower part of the base part, as the center of mass of the robot moves away from the base part, the load on the shoulder part and the base is increased. The dynamic characteristics and stability are inferior, and there is a problem in that the capacity of the shoulder motor and the base motor is increased.

셋째, 아암부가 4절링크 방식의 어깨부에 의해 상하로 이동되도록 되어 있으므로 상부작업 범위가 좁은 문제점이 있었다.Third, since the arm portion is to be moved up and down by the shoulder section of the four-section link system, there was a narrow upper working range.

본 발명은 상술한 바와같은 문제점을 감안하여 창출된 것으로서, 구조가 간단하고, 작업 범위가 넓으며, 동역학적 특성 및 안정성이 향상되도록 개선된 수직다관절 로보트를 제공하는데 그 목적이 있다.SUMMARY OF THE INVENTION The present invention has been made in view of the above-described problems, and an object thereof is to provide an improved articulated robot, which has a simple structure, a wide working range, and improved dynamic characteristics and stability.

이와같이 구성된 본 발명에 따른 수직다관절 로보트는 다음과 같이 동작된다.The vertical articulated robot according to the present invention configured as described above is operated as follows.

먼저 제4도에 도시된 바와같이, 베이스부(21)의 일축에 설치된 구동수단(30)으로서의 제1축모터(31)의 구동에 따라 그 동력이 제1베벨기어(33)와 제2베벨기어(33)를 통해 베이스부(21)의 상부에 베어링에 의해 회동가능하게 설치된 브래킷(34)으로 전달되게 됨에 따라 상부에 그 후단이 좌우로 회동가능하게 설치된 어깨부(22)가 제3도에 도시된 바와같이 화살표 A 또는 B 방향으로 회전하게 된다.First, as shown in FIG. 4, the power is driven by the first bevel gear 33 and the second bevel according to the driving of the first shaft motor 31 as the driving means 30 provided on one shaft of the base portion 21. As shown in FIG. As the shoulder portion 22 is pivotally mounted to the upper side of the base portion 21 by the bearing and is pivotably installed at the rear end thereof, the shoulder portion 22 is rotatably installed at the upper side of the base part 21. As shown in the figure, the direction of rotation is the arrow A or B.

또한 어깨부(22)는 제2축모터(26)의 구동에 따라 그 후단을 중심으로 화살표 C 또는 D 방향으로 회전하게 된다.In addition, the shoulder 22 is rotated in the direction of the arrow C or D around the rear end in accordance with the drive of the second shaft motor 26.

And rotate in the direction of arrow I or J as shown in FIG.

이와같이 동작되는 본 발명에 따른 수직다관절 로보트는, 손목부(25)를 회전시키는 제5축모터(29)가 아암(23)을 회전시키는 제4축모터(28)와 상하로 나란하게 아암(23)의 후단부에 설치되고, 어깨부(22)가 베이스부(21)의 상부에 설치되어 있으므로, 종래 손목부 고동모터가 아암의 선단에 설치되고, 어깨부가 베이스부의 하부에 설치되던 방식에 비하여 로보트의 질량 중심위치가 베이스부에 가깝게 됨에 따라 베이스부에 걸리는 하중이 적어 로보트의 동역학적 특성 및 안정성이 향상되게 된다.In the vertical articulated robot according to the present invention operated as described above, the fifth shaft motor 29 for rotating the wrist part 25 is parallel to the fourth shaft motor 28 for rotating the arm 23. 23), the shoulder 22 is provided on the upper portion of the base 21, so that the conventional wrist-driven motor is installed on the tip of the arm, and the shoulder is installed on the lower portion of the base. In comparison, as the center of mass of the robot is closer to the base part, the load on the base part is less, thereby improving the dynamic characteristics and stability of the robot.

그리고 로보트의 질량 중심위치가 베이스부에 가깝게 위치하게 됨에 따라 베이스부 구동용 모터의 용량을 줄일 수 있게 되어 베이스부의 소형화 및 경량화가 가능하고, 타이밍벨트를 사용하여 아암을 회전시키도록 되어 있으므로 아암을 정확하게 회전시킬 수 있게 된다.As the center of mass of the robot is located close to the base part, the capacity of the motor for driving the base part can be reduced, so that the base part can be reduced in size and weight, and the arm is rotated using a timing belt. It can be rotated accurately.

또한 어깨부가 4절링크 방식으로 구성된 종래의 방식에 비하여 구조가 간단하여 보수유지 작업이 간편하게 되고, 로보트의 상부작업 범위가 넓어지게 된다.In addition, the shoulder portion is simpler structure compared to the conventional method consisting of a four-section link method, maintenance and maintenance work becomes simple, and the upper work range of the robot is widened.

이상에서 설명한 바와같이 본 발명 수직다관절 로보트에 의하며, 소량, 경량으로 구조가 간단하고, 상부작업 범위가 넓으며, 동역학적 특성 및 안정성이 향상되게 되는 이점을 가진다.As described above, according to the vertical articulated robot of the present invention, the structure is simple in a small amount and light weight, the upper working range is wide, and the dynamic characteristics and stability are improved.

본 발명에 따른 수직다관절 로보트는 특히 작업공간이 협소하고 작업환경이 열악한 곳에서의 작업 예를들면 선체 블록의 용접작업등에 유리하다.The vertical articulated robot according to the present invention is particularly advantageous in the work where the working space is narrow and the working environment is poor, for example, welding of the hull block.
