Abstract
Dans la présente invention, l'invention concerne un dispositif d'inspection de position de collage pour inspecter des positions de collage, sur un substrat rectangulaire, d'un article collé rectangulaire qui a été collé de façon à avoir quatre côtés parallèles aux quatre côtés du substrat. Ce dispositif d'inspection de position de collage comprend : une table d'inspection sur laquelle est formée une région de placement pour placer, sur cette dernière, un substrat sur lequel un article collé a été collé ; quatre unités de mesure optique qui sont montées sur la table d'inspection, font face à quatre coins du substrat et quatre coins de l'article collé, et mesurent optiquement des distances entre des bords latéraux de l'article collé et des bords latéraux du substrat parallèles aux bords latéraux de l'article collé, au niveau des quatre coins ; et une unité d'affichage de résultat de mesure qui est reliée aux quatre unités de mesure optique et affiche, en tant que résultat de mesure, les distances mesurées respectivement par les quatre unités de mesure optique. Grâce à cette configuration, il est possible d'améliorer la précision d'inspection de positions de collage, sur un substrat rectangulaire, d'un article collé rectangulaire qui a été collé de façon à avoir quatre côtés parallèles aux quatre côtés du substrat.
