Chip Mounting Position Control Method and Positioning Device of Orthogonal Robot for Chip Mounter

摘要

The present invention relates to a chip mounting position control method and a position control device of an orthogonal robot for a chip mounter, wherein the head unit is moved to a corrected position in which an error in position control is corrected by an error angle between the front and rear movement axes and the left and right movement axes. Regardless of the angle, accurate position control to the target moving position is achieved. In the present invention, the error angle of the forward and backward movement axis with respect to the perpendicular direction of the left and right movement axis of the head unit is determined, the target movement position to move the head unit is determined, and the actual movement of the head unit generated by the target movement position and the error angle. The correction position obtained by correcting the error value between positions to the target movement position is obtained, and the correction position is used as the movement position of the head unit.
