Abstract

An umbilical member attachment device including a base part attached detachably to a first member and a second member of a robot, the first member and the second member rotating relative to each other; a first fastening part attached to the base part to fasten the first umbilical member; and a second fastening part attached to the base part to fasten the second umbilical member. The second fastening part has an attachment member attached to the base part and a fastening member fastening the second umbilical member to the attachment member, and the attachment member is provided detachably from the base part together with the second umbilical member in a state where the first umbilical member is fastened by the first fastening part.

First claim

The invention claimed is:

1. A robot, comprising:
a first member and a second member which rotate relative to each other;
a plurality of umbilical members including a first umbilical member and a second umbilical member and having:
movable portions movable between the first member and the second member, and
each of the plurality of umbilical members having a nonmoving portion fixed on the first member; and
a pair of umbilical member attachment devices attached to the first member and the second member, respectively;

a servo motor driving the robot; and
a power supply supplying power for maintaining positional information of the servo motor,
wherein each of the pair of umbilical member attachment devices comprises:
a base part attached detachably to the first member or the second member;
a first fastening part attached to the base part to fasten the first umbilical member; and
a second fastening part attached to the base part to fasten the second umbilical member,
wherein the second fastening part has an attachment member attached to the base part and a fastening member fastening the second umbilical member to the attachment member, and
wherein the attachment member is provided detachably from the base part together with the second umbilical member in a state where the first umbilical member is fastened by the first fastening part,

wherein the first umbilical member includes a power line and a signal line to the servo motor, and
wherein the second fastening part fastens the second umbilical member in a manner detachable from the robot in a state where the servo motor and the power supply are connected.

2. The robot according to claim 1 ,
wherein the first fastening part has a first attachment member attached to the base part and a first fastening member fastening the first umbilical member to the first attachment member,
wherein the attachment member and the fastening member of the second fastening part are respectively a second attachment member and a second fastening member, and
wherein the second attachment member is provided detachably from the base part together with the second umbilical member in a state where the first attachment member is attached to the base part, while the first attachment member is provided detachably from the base part together with the first umbilical member in a state where the second attachment member is attached to the base part.

3. The robot according to claim 2 ,
wherein the first attachment member and the second attachment member are arranged adjoining each other in a direction vertical to a longitudinal direction of the plurality of umbilical members.

4. The robot according to claim 1 , further comprising a third fastening part attached to the base part to fasten the first umbilical member and the second umbilical member.

5. The robot according to claim 1 ,
wherein the plurality of umbilical members include a replacement umbilical member fastened to one of the first fastening part and the second fastening part, and
wherein the replacement umbilical member is fastened to a predetermined position by the first fastening part in a first mode and is fastened to the same predetermined position by the second fastening part in a second mode.

6. The robot according to claim 1 , further comprising a first distribution board to which the first umbilical member is connected and a second distribution board to which the second umbilical member is connected.

7. The robot according to claim 1 , further comprising a cover covering the movable portions of the plurality of umbilical members.

8. The robot according to claim 1 , further comprising a pipe part arranged along an axial line, the axial line being a center of rotation of the first member and the second member,
wherein the plurality of umbilical members are passed through an inside of the pipe part.
