Abstract

The invention discloses a robot joint arm and a robot. The robot joint arm comprises a shell, and a motor is arranged in the shell the robot joint arm; further comprises a multiplex encoder, the multiplexing encoder is in an annular shape and the multiplexing encoder is arranged on a rotating shaft of the motor in a sleeved mode, the inner ring part of the multiplex encoder is a photoelectric encoder, and the outer ring part is a magnetic encoder. According to the robot joint arm, the optical encoder and the magnetic encoder which are independently arranged in the prior art are integrated intoa whole, the axial size of the motor can be greatly reduced, and the functional density of the motor can be improved, the axial size of the joint arm of the whole robot can be reduced, and the photoelectric encoder and the magnetic encoder cannot be influenced so that the multiplex encoder can simultaneously have the functions of detecting the rotating speed and position of the rotating shaft andthe phase change point of the motor.

Description

technical field [0001] The invention relates to the technical field of robots, in particular to a robot joint arm and a robot. Background technique [0002] There is a motor in the robot joint arm as a driving mechanism. In order to ensure the reliable operation of the motor, a photoelectric encoder and a magnetic encoder are usually installed. The photoelectric encoder is used to detect the speed and position of the motor rotor, and the magnetic encoder is used. Used to detect the commutation point of the motor. [0003] In the prior art, the photoelectric encoder and the magnetic encoder are installed independently, which leads to a larger axial dimension of the motor, which in turn leads to an increase in the axial dimension of the entire robot joint arm. [0004] Therefore, how to provide a robot articulated arm with a smaller axial dimension is still a technical problem to be solved urgently by those skilled in the art. Contents of the invention [0005] The object ...
