Verfahren und Vorrichtung zur Kontrolle eines lötfreien Verbinders durch Bildbearbeitung

摘要

A solderless terminal inspecting method and apparatus for determining if a solderless terminal has been satisfactorily crimped against an electric conductor has a main illuminating device for illuminating a solderless terminal having illuminating elements extending in substantially the same direction as a length of a solderless terminal. The inspecting apparatus also includes an auxiliary illuminating device for illuminating a solderless terminal in a direction opposite to the illuminating direction of the main illuminating. The apparatus also includes an illuminated image receiving device for receiving the illuminated image of the solderless terminal. The image of the solderless terminal received by the image receiving device is binary-coded by using at least one binary level determined according to an area histogram which has been obtained in advance.
