Industrial robot and system having device for exchanging lubricant

Abstract

An industrial robot (12) comprising a plurality of joints (20a-20f); a plurality of links (16a-16f) arranged to be driven in movement by the joints; a housing (26) comprising a link, an opening (24a-24c) and a cover (22a-22c) for selectively closing the opening, the housing defining an inner region (44) and an outer region (28) of the industrial robot; and for at least one joint, a kinematic device (38a, 38b, 40a, 40b, 42a, 42b, 43a, 43b) associated with the joint and positioned in the interior region and at least one fluid connection (50a-50c) in fluid communication with the kinematic device, each fluid connection being arranged to supply or receive lubricant (48) to or from the kinematic device, and is accessible from an outer region through the opening when the cover is removed for connecting a service tool (32) to the fluid connection. A system (10) comprising an industrial robot and a service tool is also provided.
