ROBOT AND MANUFACTURING METHOD FOR ROBOT
First Claim
1. A manufacturing method for a robot, comprising:
- a robot including a base, a multi-joint arm provided in the base, a wrist member coupled to the multi-joint arm, and a hand mounted with an end effector turnably coupled to the wrist member;
the wrist member including a motor and a housing, the motor including a rotor, a rotor shaft and a stator, and the housing including a motor housing recess, in which the motor is positioned and housed;
forming a motor incorporating recess including a positioning section for the stator, a screw hole for a screw for fixing the stator incorporated in the motor incorporating recess, and a heat radiation groove section recessed from a sidewall of the motor incorporating recess toward the outer side of the housing;
positioning the stator in the positioning section of the motor incorporating recess and then fixing the stator with the screw;
injecting a heat radiation member having fluidity in a normal state and high thermal conductivity into a gap between the stator and the heat radiation groove section; and
solidifying the heat radiation member.

Abstract
A robot includes a base, a multi-joint arm provided in the base, and a wrist member configuring a part of the multi-joint arm. The wrist member includes: a motor including a rotor, a rotor shaft, and a stator; and a housing including a motor housing recess, in which the motor is positioned and housed, and forming an external shape of the wrist member. The housing has a motor incorporating recess including a positioning section for the stator, a hole section for fixing the stator incorporated in the motor incorporating recess, and a heat radiation groove section on a sidewall of the motor incorporating recess. A heat radiation member is filled in the heat radiation groove section.
