Title (EN) DRILLING HEAD FOR PRINTED CIRCUIT BOARDS
(FR) TÊTE DE PERÇAGE POUR CARTES DE CIRCUIT IMPRIMÉ
Abstract:
(EN) Drilling head (11) for printed circuit boards, includes a central body (13) which is associated with a drilling spindle (15), moving along the direction "Z" with respect to the central body (13), and bearing a drilling tool (16), in which said spindle (15) is associated with the central body (13) with the interposition of a linear motor (19) comprising three coils (19a, 19b, 19c,) arranged at 120° around the "Z" axis and fixed to the structure of the spindle (15), immersed in the magnetic field generated by a corresponding channel of permanent magnets so that the three axial components of the magnetic forces produced by the three coils (19a, 19b, 19c) generate a resultant which coincides substantially with "Z" axis of the spindle (15), thus improving in significant way the accuracy and performance of the drilling head.
(FR) Une tête de perçage (11) pour des cartes de circuit imprimé comprend un corps central (13) qui est associé à une broche de perçage (15) se déplaçant suivant la direction « z » par rapport au corps central (13) et portant un outil de perçage (16). Ladite broche (15) est associée au corps central (13) avec l'interposition d'un moteur linéaire (19) comprenant trois bobines (19a, 19b, 19c) disposées à 120° autour de l'axe « z » et fixées sur la structure de la broche (15), immergé dans le champ magnétique généré par un canal correspondant d'aimants permanents de sorte que les trois composantes axiales des forces magnétiques produites par les trois bobines (19a, 19b, 19c) génèrent une résultante qui coïncide sensiblement avec l'axe « z » de la broche (15), d'où l'amélioration significative de la précision et de la performance de la tête de perçage.
