Abstract: Aiming at the problem of the defect and inefficient of the binder clips automated assembly system assembly loading and unloading process, a new loading and unloading synchronization device which was twostage intermittent push plate was proposed. This synchronization device was used to realize the function of unassembled clip body loading and assembled binder clip unloading. Using the Siemens S7200 series PLC controller to roundly control loading and unloading device, transport device and assembly device, the automatic assembly machine were implemented. Based on the loading and unloading cylinder dynamics simulation with the Simulink simulation tool of Matlab, each parameter value in the process of pneumatic launch was determined, and the optimal value of working pressure and the platform assembly efficiency were worked out. The experimental results indicate that the loading and unloading synchronization device has highest work efficiency and the lower fault rate,which can effectively replace manual loading unloading,while the cylinder pressure is 0.2MPa and the loading and unloading time is 0.693s.
