COMPONENT INSPECTING MACHINE AND COMPONENT MOUNTING MACHINE

摘要

This component mounting machine also serves as a component inspecting machine which inspects the state of arrangement of components mounted on a substrate. The component mounting machine captures, under prescribed imaging conditions, images of specific areas 76 defined inside an arrangement location 70 of a component P on a substrate, calculates the brightness within each specific area 76, from the captured images, and compares the brightnesses with a preset threshold to assess whether or not the component has been arranged within a permissible range in the arrangement location 70. It is thus not necessary to incorporate data used in a conventional substrate external appearance inspecting machine (in other words, component data required to assess discrepancies in the attitude or position of the component) in order to perform the assessment by comparing the brightnesses within the specific areas 76 with the threshold. The external appearance of the substrate can therefore be inspected in a simple manner.
