METHOD AND SYSTEM FOR CARRYING SUBSTRATE

摘要

A carrying system provided with a substrate sensor for detecting carriage of the substrate to a specified position in the carrying system by detecting a reference point of the substrate. Mounting position of the substrate optimal for the mounting work of a component mounting head is set at a position matching the center of the carrying system in the carrying direction so as to shorten the moving distance of the component from a component feeder to the substrate, and set at a position matching a component camera, when it is used, and the carrying direction. The controller of a component mounter positions the substrate at an optimal mounting position by advancing the substrate further by a moving amount corresponding to that substrate from the position where it is detected by the substrate sensor. The moving amount corresponding to the type of the substrate is determined based on the dimensional information of the substrate and an offset distance for the optimal mounting position of the substrate sensor. Consequently, the substrate can be positioned accurately at a target position on the carrying system set for each kind of substrate based on the detection signal from the substrate sensor.
