Abstract

The invention provides a robot joint assembly and a robot with the same. The robot joint assembly comprises an arm, a drive part arranged on the arm, a transmission part arranged on the arm and driven by the drive part to rotate and a control part arranged on the arm and connected with the transmission part to lock or unlock the transmission part. As the control part is adopted for controlling the moving state of the transmission part, in other words, the moving state of the transmission part is controlled to be in the locked state and in the unlocked state, and when the transmission part is in the normal working state, the transmission part is in the released state; and when the transmission part is in the abnormal working state, the transmission part is in the locked state. The control part is arranged to effectively control the transmission part, the phenomenon that the transmission part loses control and falls down is effectively prevented, and the safety performance of the robot joint assembly is improved. The problem that a transmission part in the prior art is likely to crash and fail is effectively solved.

Description

Technical field [0001] The invention relates to the technical field of robots, and in particular to a robot joint assembly and a robot having the same. Background technique [0002] Synchronous belt transmission is widely used in horizontal articulated robots due to its advantages of accurate transmission ratio, high transmission efficiency and long transmission distance. The transmission of the mobile joints of the SCARA robot is realized by the synchronous belt wheel, the synchronous belt, the ball screw and the ball spline shaft. The servo motor of the moving joint drives the ball screw through the timing belt, and the ball screw moves up and down through the screw nut drive spline shaft, that is, the control of the ball spline shaft position is realized through the timing belt drive. However, the timing belt is broken due to work wear, aging and other reasons, causing the spline shaft to fall out of control, which is easy to cause engineering accidents such as damage to the ...
