Abstract: Aiming at the problem of long-term damage to the service life of a retail cabinet under high load, the structure and transmission scheme of the automatic pickup door mechanism were designed. The principle of motion, degree of freedom and trajectory description of the CAM connecting rod combination mechanism were analyzed theoretically. The results indicate that the kinematic analysis of the mechanism is carried out by using the Solidworks Motion simulation software, the angular position relation between the driving member and the driving member under the condition of the known speed curve can be obtained, and the correctness of the analysis result is verified by comparison with the theoretical analysis. The velocity and acceleration of the follower are obtained to work out the movement stability and noise resistance, meet the design requirements are met, and verify the rationality of the design of the mechanism.
Key words: TRIZ; cam-linkage combined mechanism; degree of freedom; kinematics analysis; motion law
