Wire body processing structure for robot
First Claim
1. A wire body processing structure for a robot having a wrist, a base end of which is connected to a forearm in a rotatable manner about a first axis and a distal end of which has a plurality of working tools attached thereto, the wire body processing structure comprising:
- a through-path extending therethrough along the first axis from the forearm to the distal end of the wrist;
a first conduit accommodated within the through path and having flexibility and disposed along the first axis;
a second conduit having flexibility and inserted inside the first conduit along longitudinal direction, andan attachment flange member configured to attach the plurality of working tools to the distal end of the wrist,wherein a first wire body for one of the working tools is disposed so as to extend longitudinally through the second conduit,wherein a second wire body for another one of the working tools is disposed so as to extend longitudinally through a space between the first conduit and the second conduit,a distal end of the first conduit is engaged with a hole formed in the wrist in a movable manner along the first axis, andwherein the wire body processing structure comprises a movement limiting unit that limits movement of the first conduit along the first axis so as to prevent the first conduit from protruding toward the attachment flange member beyond a distal-end surface of the wrist.

Abstract
Provided is a wire body processing structure for a robot having a wrist, a base end of which is connected to a forearm in a rotatable manner about a first axis and a distal end of which has a plurality of working tools attached thereto. The wire body processing structure includes a first flexible conduit disposed along the first axis from the forearm to the distal end of the wrist and also includes a second flexible conduit disposed longitudinally within the first conduit. A first wire body for one of the working tools is extended longitudinally through the second conduit. A second wire body for another one of the working tools is extended longitudinally through a space between the first conduit and the second conduit.
