Aiming at the operation to the labels, the use of the existing vacuum suckers can barely finish the labeling work, and labels folds tend to appear in the labeling process. At the same time, it can not provide sufficient positive pressure and can not guarantee the firmness of the sticker of the labels when it is stuck of the label by providing positive pressure. Therefore, the vacuum system loop matching label operation was researched, and the porous array vacuum sucker was designed. The key parameters of the vacuum chuck, such as the diameters of the trachea, the size of the holes, the numbers of the holes, the distance of the holes, were optimized by finite element simulation.
