Gripping mechanism for inspection of reticle inner pod

Abstract

A gripping mechanism for inspection of a reticle inner pod includes a quadrilateral frame and fourth gripper units. The four gripper units are respectively disposed at four border strips of the quadrilateral frame and are opposite in pairs. Each gripper unit has a body, a first gripping portion and a second gripper portion. The first and second gripping portions are respectively located on different positions of the body. The first gripping portions form a first gripping plane, and the second gripping portions form a second gripping plane. At least two adjacent gripper units have a power member, which is in power connection with the body so as to adjust a distance between two bodies opposite to each other. The gripping mechanism for the inspection of the reticle inner pod is capable of securely gripping the reticle inner pod during transportation or turning of reticles.
