Claim 0:
1. A semiconductor-machine automatic leveling apparatus, comprising:
an inclination adjusting gear configured to drive one side of a tabletop of a wafer transfer machine to move up and down;
a motor and a driving gear, the driving gear being mounted on a rotation shaft of the motor, and the driving gear being engaged with the inclination adjusting gear; and
an inclination acquisition mechanism and a controller, the inclination acquisition mechanism being configured to acquire inclination information of the tabletop of the wafer transfer machine, the inclination acquisition mechanism being electrically connected to the controller, the controller being electrically connected to the motor, and the controller being configured to control the motor to operate according to the inclination information,
wherein the inclination acquisition mechanism comprises a base arranged in parallel to the tabletop, a pressure-sensitive sensing element arranged on the base, and a movable member movably arranged on the base, the movable member being arranged adjacent to the pressure-sensitive sensing element, and the movable member is configured to contact the pressure-sensitive sensing element when the base tilts, the pressure-sensitive sensing element is configured to sense a pressure applied by the movable member, convert the pressure into an electrical signal, and send the electrical signal to the controller, and the controller controls the motor to operate according to the electrical signal.
