Abstract

L'invention porte sur un dispositif de commande pour le montage de vis sur un disque dur, lequel dispositif de commande comprend un tournevis électrique, un contrôleur de tournevis électrique connecté au tournevis électrique, un socle du disque dur, un moteur pas-à-pas connecté au socle de disque dur et un circuit de commande du moteur pas-à-pas. Il comprend également un équipement de commande de comptage, qui se connecte au signal du contrôleur de tournevis électrique et au signal de circuit de commande du moteur pas-à-pas pour commander le fonctionnement automatique du moteur pas-à-pas lorsque le nombre de vis montées sur chaque disque dur atteint une valeur préréglée. Comme l'équipement de commande de comptage est ajouté dans le pilote de commande pour le montage de vis sur un disque dur, l'invention permet de calculer le nombre de vis montées sur chaque disque dur et commander le fonctionnement automatique du moteur pas-à-pas lorsque le nombre de vis montées atteint une valeur préréglée. Ainsi, après avoir terminé le traitement dudisque dur, l'opérateur n'a pas besoin d'actionner le moteur pas-à-pas manuellement, mais commande le fonctionnement automatique du moteur pas-à-pas par l'équipement de commande de comptage et transmet le disque dur terminé à la table de travail suivante, réduisant ainsi la procédure opérationnelle.
