Abstract

La présente invention se rapporte à un dispositif automatisé destiné à réaffûter un foret qui réaffûte un bord coupant d'un foret pour le traitement d'une carte de circuit imprimé par le biais d'un processus continu. La présente invention comprend : un rotor (100) qui tourne horizontalement par phases, et possède un support (130) de foret dans chaque direction de rotation ; un premier système de contrôle optique (200) qui photographie un bord coupant d'un foret (10) monté sur ledit support de foret ; un robot (300) de chargement de foret qui reçoit des informations de position de bord coupant du foret en provenance dudit premier système de contrôle optique (200), et monte sur le foret sur ledit support de foret par la correction de la position du foret de sorte que le bord coupant du foret soit exposé depuis un bord du support (130) de foret à une longueur prédéfinie ; un organe de réaffûtage (400) qui affûte le bord coupant dudit foret ; et un robot (700) de déchargement de foret qui détache, du support de foret, le foret qui a été complètement affûté.
