US 10,625,431 B2 · Robot and method for mounting balancer to robot

Abstract

A robot includes a robot arm, a balancer, and a first mounting portion and a second mounting portion. The balancer is pressurized in advance by a predetermined amount of pressure and contracted to a dimension smaller than a predetermined mounting dimension of the robot arm. The first mounting portion and the second mounting portion are disposed on the robot arm to respectively accept a first end and a second end of the balancer so that the first end and the second end of the balancer are mounted on the robot arm. At least one mounting portion among the first mounting portion and the second mounting portion accepts the corresponding end, among the first end and the second end, of the balancer in a direction approximately parallel to a direction in which the balancer is expanded and contracted.

Dependent claims

A robot comprising:

a robot arm;
a balancer comprising a rod and a cylinder such that a fluid in the cylinder urges the rod to contract into the cylinder in a longitudinal direction of the balancer;
a first mounting portion mounting a first end of the balancer to the robot arm;
and
a second mounting portion mounting a second end of the balancer to the robot arm,
wherein the second mounting portion comprises a connection mechanism generating a connection force in a direction approximately parallel to the longitudinal direction of the balancer such that the connection force is urging the rod to expand to a mounted length of the balancer in the longitudinal direction of the balancer.
