摘要:
A system for controlling acceleration and deceleration of a horizontally articulated robot computes the distance from the center of rotation of the robot (A) having a plurality of arms (3, 5) angularly movable in horizontal planes to a reference position such as a wrist (51) at the distal end of the arms (3, 5), and establishes an acceleration for the movement of the distal end of the arms (3, 5). A servomotor for angularly moving the arms (3,5) can effectively be utilized and the arms (3, 5) can quickly and smoothly be moved.

A heat eliminator intercepts a heat transmission in a laser robot which has a robot base (12), a robot arm (16) joined for swing motion to a robot swivel post (14) set upright on the robot base (12), a laser beam projecting unit (20) attached to an extreme end of the robot arm (16), and a drive motor (Mv) for driving the robot arm (16) for a swing motion through a precision transmission mechanism (30, 32, 34) inserted between the robot swivel post and the robot arm, from the drive motor to the precision transmission mechanism. The heat eliminator is provided with a bracket member (26) arranged between the precision transmission mechanism (30, 32, 34) and the drive motor (Mv) with one end in contact with the end surface of the drive motor on the side of the output shaft thereof and the other end in contact with the precision transmission mechanism, and an annular cooling water passage (50) formed in the bracket member (26). Cooling water is supplied into the annular cooling water passage (50) formed in the bracket member (26) from a cooling water source (70) for supplying cooling water to the laser beam conduit lines of the robot arm (16) to cool the bracket member (26) to absorb heat generated by the drive motor (Mv) by the bracket member (26), so that the heat transmission to the precision transmission mechanism (30, 32, 34) is intercepted.

The arc current is divided into two areas each corresponding to a 1/4 period of weaving, the two areas are compared with each other, and an area corresponding to a predetermined time period at the end portion of the larger area is substrated from the larger area and another area comparison is performed. The movement of the welding torch is compensated in accordance with the predetermined correction function, so that, even when an actual weld line of base metals to be welded deviates from an instructed weld line, the welding torch is correctly moved along the weld line of the base materials and arc welding is performed.
