Under the background of high labor cost of bottle sorting and the traditional mechanical structure cannot meet the requirements of multi-bottle flexible sorting,the flexible sorting system based on ABB robot was designed by replacing the traditional mechanism with the industrial robot,so as to realize the cylindrical bottle surface detection workstation suitable for multi-dimensional flexible production.By analyzing the formula of cylinder bottle size change and sorting operation position,two ABB industrial robots were used as actuators,and the translation function was used to realize the flexible adjustment of feeding,testing,sorting and other actions.The servo gripper was used as the end actuator to achieve the clamping of bottle with different mouth diameters.Mitsubishi PLC was taken as the control center,touch screen was taken as man-machine interaction interface,the system equipment coordination control and the interface monitoring of various functions were achieved through process design and program interface design.The debugging result shows that the system can realize automatic sorting of bottles with different sizes in the applicable range on the basis of the instruction of reference bottles,and the touch screen operation is convenient to meet the demand of flexible production.
