  • Method and apparatus for testing cassette pod door
    Patent number: 6595075
    Abstract: A method and an apparatus for testing the unlatching torque of a cassette pod door in order to determine whether a cassette pod door is completely unlatched by latch keys of a door opener in a loadport. When a failure of unlatching operation is indicated, the apparatus reverses the rotational direction of the DC motor and thus, turning the latch keys in an opposite direction to re-latch the cassette pod door onto the cassette pod so that the pod can be securely removed from the loadport without danger of accidental opening of the door.
