  • Publication number: 20030106776
    Abstract: In a work conveying system including at least a work holder for holding a work and a horizontal mover for moving the work holder horizontally in an upper ceiling space within a clean room, the work being conveyed to each of plural processing apparatuses. The horizontal mover has at least one linear moving mechanism including a duct with an internal guide, a traveling body engaging the guide and traveling through the traveling path defined by the duct, and a slider connected to the traveling body for travel with the traveling body on the exterior of the traveling path. The work holder is attached to the slider. Air cleaners are disposed at suitable intervals in the traveling path to clean the air therein and to discharge the cleaned air to the exterior. The traveling path accommodates a drive source, a drive mechanism, and a power supply.

  • Patent number: 6471462
    Abstract: A carrier handling apparatus of an IC module handler includes a carrier transferring unit for holding one side of the carrier to transfer the same between the various processes, and a carrier positioning unit for precisely positioning the carrier. The carrier handling apparatus includes a carrier for transferring predetermined modules, a carrier transferring unit for transferring the carrier from a loading location to an unloading location, and a carrier positioning unit for precisely positioning the carrier in the loading and unloading locations, thereby allowing IC modules contained in a tray to be accurately loaded into the carrier or unloaded therefrom by a pick-up means. According to another aspect of the present invention, a slider is installed to be moved along the traveling path of the carrier, and is provided with a pair of fingers that can be withdrawn or spread by one cylinder, so that the area required to install the carrier transferring apparatus can be minimized.

  • Patent number: 6367374
    Abstract: A product-carrying unit side portions extending along two opposite regions for engagement with respective support features of a product treatment chamber. A floor region of the unit extends between the side portions and consists of an array of floor region portions with together define a discontinuous upper product-carrying surface of the unit. The surfaces are suitably defined by the upper surfaces of the ribs of the unit. The spaces between the top surfaces of the ribs provide access to the underside of product supported on the discontinuous product supporting surface of the unit and enable heat exchange contact between the heat exchange medium and the underside of the product. The floor region of the unit is shaped to define ducts through which flow of heat exchange medium is directed for contact with the underside of the product supported on the unit.
