Patent number: 11130224Abstract: A parallel link robot includes: a base portion; a movable portion; link portions coupling the base and movable portions; and actuators attached to the base portion and driving the respective link portions. Each of the link portions includes drive links swung around axes by the respective actuators, and two each of the passive links parallel to each other and swingably arranged between the drive link and the each of the movable portions. The robot includes a drive unit disposed parallel to the two passive links of at least one of the link portions and between the passive links and drives a mechanical unit attached to the movable portion. The drive unit is attached to the drive link with a joint, swingably coupling the drive unit to the drive link around at least mutually intersecting axes, on a straight-line coupling swinging center points of the passive links and the drive link.Type: GrantFiled: December 5, 2019Date of Patent: September 28, 2021Assignee: FANUC CORPORATIONInventor: Hyunchul Souk

Patent number: 9694493Abstract: An umbilical member arrangement structure capable of properly arranging an umbilical member in a parallel link robot. A first additional actuator is arranged on a passive link part of a parallel link robot. An Umbilical member is withdrawn from an opening formed on a generally circular bottom surface of a base part, while having a margin, approaches the passive link part, while extending in an intersecting direction with respect to a longitudinal direction of the passive link part, and is connected to the first additional actuator. The “intersecting direction” means a direction extending at an angle of 70 to 110 degrees, preferably 80 to 100 degrees, more preferably about 90 degrees, with respect to the longitudinal direction of the passive link part.Type: GrantFiled: September 4, 2013Date of Patent: July 4, 2017Assignee: FANUC CORPORATIONInventor: Hyunchul Souk
