Substrate supply apparatus

摘要

A substrate supply apparatus includes a substrate-accommodating section for accommodating a substrate on which electronic components are to be mounted, a substrate-width-adjusting device, a transporting device, a substrate-sucking device, and an elevating device. The accommodating section has substrate-width-regulating sections a distance between which can be adjusted in a width direction of the substrate. The adjusting device adjusts the distance between the regulating sections by moving one of the regulating sections in the width direction. The transporting device is supported by the regulating sections, has a pair of rails, is arranged above the accommodating section, and transports the substrate to an electronic component-mounting apparatus. The sucking device has a long substrate-sucking arm and a plurality of short substrate-sucking arms. Each of the substrate-sucking short arms is position-changeably installed on the long substrate-sucking arm. The elevating device supports and vertically moves the sucking device so that the sucking device transfers the substrate to the transporting device. The elevating device is disposed at a center of a space between the pair of rails in the width direction.
