Abstract: To improve the function of the egg automatic grading line, the design and analysis of the inspection equipment of an egg automatic grading line is presented in this paper. First, the layout of the inspection machine is designed in Pro/E. Second, the structure design and performance analysis of a cam weigh system of the inspection machine is carried out in Pro/Mechanism. Then, the transportation system of the inspection machine is designed as well. Finally, the structure of the transmission chain is obtained. With the optimization design and simulation of the intermittent drive mechanism in the transportation system, the kinematic performance of the inspection equipment satisfies the system requirement.

Key words: mechanical design, design of the inspection equipment, Pro/E, cam weigh system, intermittent drive mechanism
