In the field of industrial production , it is often required to complete workpiece crawl handling processes , the use of vacuum suction cups to crawl and porters pieces is relatively inexpensive method . Existing vacuum chuck used for adsorption of the smooth surface of the workpiece , for the poor surface quality of the , if obvious flange , the dimples of the workpiece will occur leakage phenomenon, so that mainly the degree of vacuum . In this paper, based on the vacuum principle workpiece poor surface conditions and the quality of the larger (80kg ) , we designed and developed a multi- lips - vacuum suction cup . The sucker can adsorb large surface roughness and quality of the workpiece , such as copper plate , electrolytic nickel plate , larger castings . The large number of documents show that the market has not yet appeared similar structure of vacuum suction cups , the emergence of the structural sucker can come in handy in many areas of national life , production . Such as wood, stone , castings , forgings , copper plate , electrolytic nickel plate , slightly rough , rough , rough surfaces parts structural constraints not easy gripping , lifting , handling, heap pile , the most good solution is to use a vacuum chuck . In this paper, Solidedge software to complete the design of multi the lips - vacuum sucker sealed lips sucker group design and the design of the overall structure of the vacuum chuck ; using Deform-3D finite element analysis software , verify that the multi the lips - vacuum sucker material choice tightness hold the effective role played by the correctness and the sucker lips of surface defects workpiece adsorption . Secondly, to design a set of tensile test equipment , complete pneumatic circuit design and application of this tensile test test station the vacuum cups lips adsorption effect . The vacuum cups lips vacuum handling technology will change the appearance of smooth workpiece carriers can only be applied to the The crawl status quo will effectively expand the field of application of vacuum technology . The chuck of the structure has to be applied in the actual production , and to obtain a better effect .
