Abstract
A sensor bracket is provided with frame members supporting an acceleration sensor, the frame members having circular arc members holding an outer periphery of a tool of a robot in a state in which circumferential-direction gaps are defined in at least one portion of the circular arc members in a circumferential direction, and a bolt thread-screwed into the frame members so as to reduce the circumferential-direction gaps.
Claims13
A sensor bracket comprising:
- a frame member supporting an acceleration sensor, and having a circular arc member holding an outer periphery of a tool, which has a first end and a second end in a longitudinal direction of the tool, supported by a robot in a state in which a circumferential-direction gap is defined in at least one portion of the circular arc member in a circumferential direction;
- a bolt thread-screwed into the frame member to reduce the circumferential-direction gap;
- and
- a support member which is long in the longitudinal direction of the tool, the support member having a first end in the longitudinal direction coupled to the circular arc member of the frame member, the support member extending in the longitudinal direction of the tool,
- wherein the acceleration sensor is fixed to a second end in the longitudinal direction of the support member.

A robot system comprising:
- a robot;
- a tool supported by a tip end of a robot arm of the robot, the tool having a first end and a second end in a longitudinal direction of the tool;
- a sensor bracket attached to the tool, wherein the sensor bracket comprises:
- a frame member having a circular arc member holding an outer periphery of the tool in a state in which a circumferential-direction gap is defined in at least one portion of the circular arc member in a circumferential direction;
- and
- a bolt thread-screwed into the frame member to reduce the circumferential-direction gap, wherein the robot system further comprises:
- an acceleration sensor supported by the sensor bracket;
- and
- a support member which is long in the longitudinal direction of the tool, the support member having a first end in the longitudinal direction coupled to the circular arc member of the frame member, the support member extending in the longitudinal direction of the tool, wherein the acceleration sensor is fixed to a second end in the longitudinal direction of the support member.
