This review describes the research background and development trend of automatic positioning manipulator in the world. According to the design requirements, the overall structure of the manipulator is designed, the overall dimension of each component of the manipulator is designed, and its strength life is checked, and the grabbing mode and part identification and positioning mode are selected and designed:1. Determine the joint form, degree of freedom and parameters of the manipulator structure.2. The grabbing mode of the grabbing end of the mechanical arm and the diameter of the grabbing vacuum disk are designed.3. Select the servo motor to control the rotation of the grabbing end when grabbing.Key words: Part automatic positioning manipulator; Structural design; Grasping method北京理工大学珠海学院 2020 届本科生毕业设计目 录1.前言.............................................................................................
