For improving the automation degree of the labeling machine, it can automatic correction, automatic labeling and automatically parse tags in function. A automatic labeling machine with visual positioning function was designed. The main actuators was designed in rotating disc structure with eight work station, and defined the task of each workstation clearly. Programmable Logical Controller (PLC),touch screen, Industrial Personal Computer (IPC),intelligent camera and customer database component of the designed electrical control system, they were connected together through the Ethernet network. By calculating the deviation value with vision system, the servo system was driven by PLC to rectify position of lable, and to complete labeling automatically. The practical application show: the number of labels per unit time increased from 300 pieces/hour to 450 pieces/hour or more. Labeling and marking of parsing information of product were done, in terms of safeguarding product quality tracking. Information of the label could be read and uploaded all data to the client database. This equipment meets the requirement of enterprise in control, improves the production efficiency and saves cost of manual labor. Economic benefits are very high.
