Abstract
A method and system for automatically attaching works to respective vehicle bodies carried on a slat conveyor using a robot. The method comprises the steps of (a) providing a base on which the robot is mounted and which is movable within a movement range, at least one part of which is alongside of the conveyor; (b) providing work feeders for sequentially feeding plural kinds of the works which are different according to vehicle types (sedan, hardtop, etc.) of the vehicle bodies to predetermined positions; (c) identifying the vehicle type of one of the vehicle bodies to which the required work is to be attached at a first position; (d) determining a target position according to the identified vehicle type; (e) controlling the robot so as to grasp the required work from the work feeders at the target position; (f) positioning the robot to a stand-by position along the conveyor; (g) detecting sequentially a deviation of a relative position toward a direction of travel of the conveyor between a tracking point and reference point since the vehicle body has arrived at a second position downstream of the first position; and (h) moving the base to follow the conveyor so that the deviation becomes zero and simultaneously controlling the robot so as to attach the grasped work to the vehicle body.
