英文摘要：

The joint based manipulator has received growing attention by designers and users owing to its wider tasking area, flexibility of movement and compact construction features. Considering the application of automatic assembly line, the required functions of manipulator are selected. Firstly, the overall designing scheme of the assembly manipulator is given, and the over- all scheme includes the main components of assembly manipulator and allcation degrees of freedom. The jib length of industrial manipulator and the angle rang of each joint are determined. And then, the specific structure of 6-DOF manipulator is designed, modeled and virtually assemblied. Meanwhile, the strength of some key parts is also checked. Finally, the kinematic model of the 6-DOF manipulator is established. Each joint motion model coordinate is established by using D-H parameter, and D-H parameters of each joint are determined. The kinematics normal and inverse solutions of the assembly manipulator are calculated and checked by using Matlab, and the results show that the established model is reasonable and correct. The design philosophy has some reference and application value for designing the joint industrial manipulator.
