The Simulation Of Non-contact Vortex Sucker’s Static Characteristics And Its PIVExperiment Research

In the recent year, the traditional moving techniques is challenged by the urgent need for non-contact moving technique of the fast-developing semi-conductor industry, especially the LCD glass substrate industry. Although the matured product like the Bernoulli sucker has been put into market, its disadvantages like the high cost and high air consumption have greatly limited its application range. In order to conquer the disadvantage of the Bernoulli sucker,Li Xin develop a new kind of sucker based on the swirl sucking mechanism.Currently the research on the swirl sucker emphasize in the optimization design of the old sucker. But lack of the model that capable of describing the sucker’s characteristics has become the bottleneck of the optimization research. This article emphasizes on the modeling and simulation of the sucker’s static characteristics. The main job of this article includes the following contents:(1)The non-contact swirl sucker’s PIV experimental bench is designed and built.The velocimetry experiment is conducted by applying the PIV technique. The flow field’s characteristics is kown by analyzing the acquired tangential velocity and radial velocity.(2)The tangential velocity distribution is simulated by applying the vortex model on the vortex sucker. The air consumption is simulated by analyzing the nozzle’s air flow characteristics. Finally the pressure distribution and lifting force model are constructed based on the result above.(3)The static pressure experiment bench is designed and constructed. The analytical models are validated by analyzing the acquired pressure distribution and lifting force data.(4)The CFD simulation of the vortex sucker’s flow field is conducted in FLUENT. Further validation of the analytical model is doned by analyzing the simulation result. The feasibility of applying PIV technique in vortex sucker’s velocimetry is also validated.
