Abstract
A vacuum for non-contact gripping can be generated using a circular air head. The present study has numerically investigated the influence of the air head shape on the vacuum lifting force and swirl flow stability in a vortex-type non-contact gripper. The grip stabilities of swirl and lifting force variations were analyzed according to the air head end-effector, head chamber, and inner column sizes. Results show that the maximum lifting force occurs at a gap thickness of about 0.5 mm . Although in general, the longer the tip length, the larger the vacuum pressure that forms, an optimum tip length exists when considering the lifting force stability as a small head height might lead to unstable swirl flow. To enhance the stability of swirl, the installation of an inner column is an acceptable alternative irrespective of the 20 to 30% reduction of lifting force.
