Title (EN) ROBOT EQUIPPED WITH HEAT REMOVING MEANS
(FR) ROBOT AVEC ORGANE D'EXTRACTION DE LA CHALEUR
Abstract:
(EN) A laser robot is equipped with a swing arm (16) mounted to a swivel post (14) implanted to a robot foundation portion (12), a laser emission device (20) provided on the tip of the robot arm (16), and a driving motor (Mv) for driving the swing operation of the robot arm (16) through a precision transmission device (30, 32, 34) placed between the swivel post and the robot arm. The robot comprises a heat removing device which includes a bracket member (26) and an annularly recessed fluid circuit (50) formed in the bracket. The bracket has one end in contact with the end surface of the driving motor on its output shaft side and the other end in contact with the precision transmission mechanism. The heat removing device is located at the joint portion between the precision transmission mechanism (30, 32, 34) and the driving motor (Mv). Cooling water is supplied to the recessed fluid circuit (50) from a cooling water supply source (70) for supplying cooling water to a laser beam conduit of the robot arm (16) so as to cool the bracket member (26). The bracket member (26) thus cooled absorbs and removes the heat of the driving motor (Mv) and prevents heat transfer to the precision transmission mechanism (30, 32, 34).
(FR) Le robot à laser décrit comprend un bras oscillant (16) installé sur un montant pivotant (14) fiché dans le socle (12) du robot, un dispositif d'émission laser (20) placé à l'extrémité du bras (16) du robot, ainsi qu'un moteur d'entraînement (Mv) servant à imprimer un mouvement oscillant au bras (16) du robot par lintermédiaire d'un dispositif de transmission de précision (30, 32, 34) situé entre le montant pivotant et le bras du robot. Le robot comporte un dispositif d'extraction de la chaleur qui se compose d'un élément à console (26) et d'un circuit hydraulique avec évidement annulaire (50) formé dans la console. L'une des extrémités de la console est en contact avec la surface terminale du moteur d'entraînement du côté de son arbre de sortie et l'autre extrémité est en contact avec le mécanisme de transmission de précision. Le dispositif d'extraction de la chaleur est disposé au niveau de la jointure entre le mécanisme de transmission de précision (30, 32, 34) et le moteur d'entraînement (Mv). L'eau de refroidissement est conduite jusqu'au circuit hydraulique évidé (50) à partir d'une source de conduction d'eau de refroidissement (70) servant à acheminer l'eau de refroidissement dans un tube conducteur de faisceau laser du bras (16) du robot, afin de refroidir l'élément à console (26). L'élément à console (26) ainsi refroidi absorbe et extrait la chaleur du moteur d'entraînement (Mv) et empêche tout transfert de chaleur vers le mécanisme de transmission de précision (30, 32, 34).
