Abstract

The flexible braking circuit for a robot arm provided by the present invention includes a permanent magnet motor, a motor driver connected to the permanent magnet motor through a three-phase circuit, and a relay connected to each phase circuit in the three-phase circuit, When the robot arm is powered off, the contacts of the relay are automatically closed, and each phase circuit in the three-phase circuit is connected to each other, so that the rotating magnetic field generated inside the permanent magnet motor can be fully utilized to convert it into a torque in the opposite direction , to prevent the rapid fall of the arm and serve as a safety precaution; when the robot arm is energized, the contacts of the relay are disconnected, and each phase circuit in the three-phase circuit is mutually disconnected to ensure the normal operation of the robot arm. Work. In addition, the invention also provides a robot arm and a robot including a flexible brake circuit.

Description

Technical field [0001] The present invention relates to the technical field of robots, in particular to a flexible braking circuit for a robot arm, a robot arm and a robot. Background technique [0002] With the advancement of science and technology, the research and application fields of robots are constantly expanding. The robotic arm is the most representative complex component in the robot system. It is the basis for the robot to complete the grasping operation and human-machine interaction. Therefore, the compactness, versatility and flexibility of its structural design are the primary factors to realize the intelligent control of the arm. At the same time, the flexibility, safety, stability and modular design of the multi-degree-of-freedom joint mechanism of the manipulator is an urgent problem to be solved. The key to evaluating the flexibility of robot movement is the design of the multi-degree-of-freedom motion mechanism of the robot's shoulder joint, elbow joint, and w...
