Abstract

Appareil et procédé de marquage laser à autofocus mécanique Contenu de l’abrégé. L’invention concerne un appareil de marquage laser comportant :- un châssis (4) supportant un dispositif d’émission (3) d’un faisceau laser acheminé à l’intérieur d’un fourreau comportant une tête (11) prolongée par un tube de protection (12); - un système de détection lorsque le tube de protection est en butée sur la tête du fourreau et sur la surface (2a) à marquer; - le dispositif d’émission est monté sur le châssis par l’intermédiaire d’une liaison glissière permettant entre le châssis et le dispositif d’émission, un mouvement de translation; - un système de déplacement (6) pour, lorsque le tube de protection est en butée sur la tête du fourreau et sur la surface de la pièce à marquer, déplacer relativement le dispositif d’émission par rapport au châssis, selon une course supplémentaire; - un système d’amortissement monté entre le dispositif d’émission (3) et le châssis (4) pour absorber au moins la course supplémentaire. Figure pour l’abrégé : Fig. 1.
