Nowadays lots of technicians assist the rehabilitation training are in great need of the hemiplegia patients in our country. By controlling the mechanism motion to assist the patients with hemiplegia rehabilitation training, and the rehabilitation robots base on the robot principlecan, which can accelerate the regenerationthe of nerve cells, it’s possible to set up the nervous system control loop. It can make the patients move voluntaryly.Based on the theoretical research of neural restoration, this paper studies the shoulder joint rehabilitation robot. The main research content includes the following aspects:This paper introduces the current situation of research on the rehabilitation robots at home and abroad, and expounds the traditional theory of the human body nerve repair after joint injury and its repair method. Based on this, it puts forward a signal superposition method, which is easy for limb joints to repair their nerves.The movement of shoulder joint is under deeply discussed and studied. A series and parallel connection3 DOF rehabilitation robot has been designed with the good characteristics positioning accuracy and adapt ability.In addition, based on the mechanism on the ontology of shoulder joint rehabilitation robots, the method of vector analysis on the positive and negative solution was adopted and with the assistant of Matlab programming software the3 D workplace mapped out. The 3D model of shoulder joint rehabilitation robots was established by using Creo2.0 three-dimensional modeling software. The kinematics simulation analysis was carried out in the early rehabilitation training period of rehabilitative training. The analysis results show that during the rehabilitation training,speed, force, torque and other factors change uniformly. There are no jumping points.The simulation structure shows that the mechanism can satisfy the basic requirement of shoulder joint rehabilitation training, which validated the rationality of mechanism design.Finally, on the basis of the finite element theory, the stress and strain analysis were carried on the components of shoulder joint rehabilitation robots. The stress and strain nephogram was obtained. Based on the analysis results of stress and strain, the structure was optimized. Finally, the structure size of the shoulder joint rehabilitation robots has been achieved, and the optimized design of the organization has been carried on.
