METHOD AND DEVICE FOR CONTROLLING CHIP MOUNTING POSITION OF ORTHOGONAL ROBOT FOR CHIP MOUNTER

摘要

PROBLEM TO BE SOLVED: To position a head unit correctly by compensating a distance error caused by the error angle between longitudinal and horizontal moving shafts. SOLUTION: A head unit 5 is moved to a correct position obtained by correcting a distance error caused by the error angle between a longitudinal moving shaft 2 and a horizontal moving shaft 1, and thus correct position control for moving it to a target position is performed regardless of the error angle. The error angle of the longitudinal moving shaft 2 with respect to the direction perpendicular to the horizontal moving shaft 1 of the head unit 5 is calculated, a target position to which the head unit 5 should be moved is determined, and a correct position is calculated through the correction of the error angle between the target position and the actual position of the head unit that depends on the error angle, and is used as the position to which the head unit 5 should move.
