Component attracted state detecting system for component mounting machine

摘要

A method and apparatus of mounting components and recognizing two different types of components, one by a photographic recognition practice and the other by an optical recognition practice. At least two pick-up devices are carried by a mounting head and a light source and background device is moveable supported by the mounting head into a first position wherein a photographic recognition method can be practiced on a component mounted on one of the pick-up devices, a second position wherein one or both of the pick-up devices may hold components for recognition by the optical device and a third position where a camera carried by the mounting head can be employed for recognizing a substrate. The control routines for each type of sensing operation are disclosed.
