In order to solve the problem of manually changing the suction cup head when applying labels to the end face of different sizes of bars,a labeling robot with an automatically replaceable suction cup head was designed.The mechanical structure of the labeling robot was designed,which consisted of a replaceable suction cup head and a suction cup head mount;the vacuum adsorption circuit for label application and an automatic suction cup head replacement circuit were built according to the working process;20 kinds of suction cup opening schemes were analyzed through ANSYS modeling,and 8 kinds of suction cup head opening schemes were initially selected;finally,100 times adsorption experiments were carried out on the primary selection of the hole opening scheme.The experimental results show that the suction cup opening scheme with the number of holes M=4,hole diameter D=6 mm and hole distance s=5 mm has the best label adsorption effect.The labeling robot designed can not only change the suction cup head automatically according to different si-zes of bars,but also achieve stable label adsorption,which is very suitable for the design requirements of the labeling robot automation.
