More Information
Summary:The device contains a cylinder fixed onto the end of a rotary shaft and fitted with sucking tubes which are selectively connected to the vacuum. The sucking tubes are mounted in such a way that they can be rotated inside the cylinder in such a way that they keep their selective connection to the vacuum. The tubes are accurately orientated by a step-by-step driving system. This device allows the micro-components to be rotated after being taken by the sucking tube. The vacuum can be transmitted irrespective of the angular positions of the tubes. L'INVENTION CONCERNE UN DISPOSITIF DE PREHENSION A BUSES MULTIPLES ORIENTABLES.LE DISPOSITIF COMPREND UNE TRINGLE 16 ENTRAINEE EN ROTATION PAR UN MOTEUR 10 ET MUNIE A SON EXTREMITE DE BUSES D'ASPIRATION 50 DE DIAMETRE DIFFERENT, DES TUBES D'ALIMENTATION 35 EN VIDE DES BUSES D'ASPIRATION, RELIES A UN COLLECTEUR 30 COMMUNIQUANT AVEC UNE SOURCE A DEPRESSION, UN BARILLET 40 FIXE RIGIDEMENT EN EXTREMITE DES TUBES D'ALIMENTATION 35 ET SUPPORTANT LES BUSES D'ASPIRATION, ET UN VERROU 80 COULISSANT DANS UNE CHAMBRE CYLINDRIQUE 38 DU COLLECTEUR 30 AFIN, SELON SA POSITION DANS LA CHAMBRE 38, SOIT D'ENTRAINER LE COLLECTEUR EN ROTATION, SOIT D'IMMOBILISER CELUI-CI PAR RAPPORT AU BATI DU DISPOSITIF.APPLICATION A UN DISPOSITIF DE PREHENSION ET DE TRANSFERT DE MICROCOMPOSANTS.
