  • Publication number: 20230422422
    Abstract: An engaging mechanism includes a casing, a first engaging member and a second engaging member. The casing has a first engaging recess and a second engaging recess. The first engaging member is slidably disposed in the casing and has a first engaging portion. The second engaging member is rotatably disposed in the casing and has a second engaging portion. When the first engaging member is located at a first lock position, the second engaging member is able to rotate between a second lock position and a second unlock position. When the second engaging member is located at the second unlock position and the first engaging member slides from the first lock position to a first unlock position, the first engaging member pushes the second engaging member to rotate toward the second lock position, such that the second engaging portion blocks the second engaging recess.

  • Publication number: 20220059382
    Abstract: A method and an apparatus for detecting positions of wafers. A rotation table, on which the wafer with an aiming feature is disposed, rotates in a direction at a faster speed while a detector detects a periphery of the wafer and provides a controller with a detection result. The rotation table rotates in an opposite direction at a slower speed after the aiming feature passes the detector, while the detector detects the periphery of the wafer and provides the controller with a new detection result. A respective detection result corresponds to a rotation angle. When the aiming feature passes the detector again, the rotation table stops rotating, and the controller computes the eccentric position of the wafer and the position of the aiming feature according to the detection results and their rotation angles. Therefore, the time for detection may decrease.
