Title:  Design of a Non-contact Vacuum Handling System Used for Processing of CD

Abstract As a new type of pneumatic components, the non-contact swirling flow vacuum cup can achieve lifting and handling the work piece in a non-contact state and other functions. Therefore, it has the advantage of non-contact, no damage and no pollution with the work piece. In the industry of semiconductor, LCD panel, pharmaceutical and other fields where the surface quality and cleanliness of the product are highly required, the non-contact swirling flow vacuum cup has a wide range of use. This paper discusses the principle of non-contact vacuum cup, and the design of an example based on this. Next, the mathematical modeling of the non-contact vacuum cups is conducted to get a preliminary understanding of its operating characteristics, and the design of a non-contact vacuum handling system, specifically including the mechanical design, pneumatic circuit design and PLC programming, is carried out, so that the performance of a complete system for the real can be studied.
