ABSTRACT:
A universal interface and transfer apparatus is disclosed which may be configured either as an indexer or a load port opener. In each configuration, the universal interface and transfer apparatus includes a port plate having a central opening, and a port door fitting within and sealing the central opening when no pod is present on the apparatus. The apparatus further includes a base and a frame mounted on and extending up from a front of the base. A modular drive assembly is mounted within an exterior side of the frame, which drive assembly includes a linear drive screw, and a motor and torque transmission mechanism for rotating the linear drive screw. A carriage is mounted on the linear drive screw such that rotation of the linear drive screw results in vertical translation of the carriage. In a first configuration, the port plate is mounted to the carriage via a bracket extending between the port plate and carriage so that rotation of the linear drive screw will vertically translate the port plate while the port door remains stationary. In a second configuration, the port door is mounted to the carriage via an arm extending between the port door and carriage, while the port plate is stationarily mounted to the frame so that rotation of the linear drive screw will vertically translate the port door while the port plate remains stationary.
