Multi-joint robot arm for complex environments

The present invention discloses a multi-joint robot arm for complex environments such as high temperature and vacuum, comprising a robot arm holder, and the robot arm hinged quick couplings; Manipulator support rail coupled to the bottom of the vacuum storage compartment, and is to provide multi-joint robot arm to maintain pivot support abutment can drive the robot arm forward and retracted a distance in the direction of the rail; hinged robot arm structure for the multi-section tube, a modular gear between each articulated robot drive joints coupled together, each of the corresponding drive joints are placed in a high temperature inside the motor driving the robot arm; the front end of the robot arm is coupled with a quick coupling, the front end of the actuator can be quickly replaced different functions; simple structure, light weight, All the electronics and the drive motor built in the robot arm inside, sealed and do, effectively protect the vacuum environment from pollution, may be without breaking the vacuum environment, the internal components of the vacuum chamber for monitoring, inspection and repair.
