Abstract
Automatic pin machine is a kind of typical equipment widely used in mechanical and electronic industry, which is mainly used for automatic assembly of pinhole parts. In order to improve the efficiency and stability of the transmission system, the dynamic performance of planetary gears is studied. This paper uses UG to establish the dynamic model of planetary gears. Dynamic simulation and its motion law are obtained using Adams. The contact force between the planet gear and the center gear fluctuates around 5000N, and increases with the load. The results show that Adams can provide an effective prediction of the dynamic characteristics of planetary gear trains, and have a certain reference value for future structural improvements.

Summary
Automatic pin machine is a kind of typical equipment widely used in mechanical and electronic industry, which is mainly used for automatic assembly of pinhole parts. The dynamic performance of the pin machine will directly affect the assembly efficiency and assembly accuracy. In order to improve the efficient and stable movement of mechanical equipment, many researchers have focused on kinematics analysis. With the development of computer technology, virtual prototyping has become one of the necessary tools for researchers. Virtual prototyping technology predict the dynamic performance of the equipment, and quickly improve the product structure and shorten the research and development cycle. To improve the comprehensive performance of an automatic pin machine, dynamic performance of the transmission system has been analyzed in this paper. The dynamic performance of the planetary gear train is obtained, which lays a foundation for the optimization design of the mechanism in the future
