Title (EN) ARTICULATED ARM TYPE INDUSTRIAL LASER ROBOT
(FR) ROBOT INDUSTRIEL A LASER DU TYPE A BRAS ARTICULES
Abstract: front page image
(EN)This invention relates to articulated arm type industrial laser robot equipped with at least two robot arms (24:26, 44:46, 82:84) of a joint coupling type that are held by robot base (21, 41, 81) either directly or through a swivel drum (42) and laser beam emission robot wrists (48, 86) held by the foremost tip (46a) of these robot arms (24:26, 44:46, 82:84). This laser robot further includes laser beam passage means (31, 50, 96) having a hollow ball spline shaft (30, 54, 94) and a ball spline nut (28, 52, 92) and extending and contracting between the two robot arms ((24:26, 44:46, 82:84) in accordance with their relative swivel motion so as to guide the laser beam introduced from outside the robot machine body to the robot wrist (48, 86).
(FR)Un robot industriel à laser du type à bras articulés comprend au moins deux bras (24:26, 44:46, 82:84) du type à accouplement par une articulation, fixés à la base (21, 41, 81) du robot soit directement soit par un tambour orientable (42). Des poignées (48, 46) d'émission de rayons laser sont fixées à la pointe (46a) de ces bras (24:26, 44:46, 82:84) du robot. Ce robot au laser comprend en outre des organes de passage (31, 50, 96) du rayon laser avec un arbre cannelé creux circulaire (30, 54, 94) et un écrou cannelé circulaire (28, 52, 92) qui s'étendent et se contractent entre les deux bras (24:26, 44:46, 82:84) du robot selon leur pivotement relatif, guidant le rayon laser introduit de l'extérieur du corps du robot jusqu'à la poignée (48, 86) du robot.
