Patent number: 7169229Abstract: The invention pertains to a coating apparatus and method in which most of the relative movement between a dispensing head and the substrate to be coated is provided by the coating head. The moving head configuration reduces the system footprint and diminishes leveling problems. A powered shuttle mechanism carries a dispensing head above a substrate to be coated while riding on a bearing located underneath the chuck holding the substrate thereby providing rigidity and reducing the system footprint. Chuck support is designed to accommodate anticipated vertical sag in the dispensing head by supporting the chuck at points along its periphery thereby permitting the chuck to sag in conjunction with the dispensing head. The shuttle mechanism is equipped with means for automatically adjusting the height of the dispensing head with respect to substrate to compensate for substrate placement error, substrate dimensional variation, and mechanical drift in the mechanical machine parts.Type: GrantFiled: February 11, 2003Date of Patent: January 30, 2007Assignee: FAStar, Ltd.Inventors: Gregory M. Gibson, Carl W. Newquist, John E. Hawes, Rene Soliz, Samer Mahmoud Kabbani, Scott A. Snodgrass, Altaf A. Poonawala, Darwin R. Frerking, Zi-Qin Wang, Ocie T. Snodgrass, Eric E. Anderson

Patent number: 6488041Abstract: The present invention relates to a system and method suitable for automatic cleaning of a coating or extrusion head of a coating apparatus. The invention includes a scrubbing station wherein a combination of physical contact and strong solvent solution combine to remove coating fluid from the exterior of an extrusion head. A second cleaning station, preferably a rinsing station then further cleans the head of coating fluid and removes solvent used at a first cleaning station. The solvent used at the rinsing station is preferably self-drying thereby obviating the need for any further cleaning action. The invention also provides for the ability to prime the coating bead at the extrusion head so as to have a fully formed bead ready before the head begins coating a substrate, thereby providing an even coating across said substrate. The priming operation preferably comprises holding the head steady over a rotating priming roller while extruding fluid preferably at a constant volumetric flow rate.Type: GrantFiled: January 8, 1999Date of Patent: December 3, 2002Assignee: FAStar, Ltd.Inventors: Gregory M.

Patent number: 6387184Abstract: A system and method for modularly interfacing wet components of a coating apparatus to the remainder of the coating apparatus comprising a station whereupon a substrate is located. A fluid cart houses the wet components of the apparatus which comprise a dispensing head in fluid connection to the fluid cart. The fluid cart can be connected to a station and a variety of different types of coating operations subsequently performed. The fluid can be readily disconnected from the station after the coating operation is complete, permitting a different fluid cart to be attached to the same station. The first fluid cart can then receive required servicing without idling the station to which it had been attached. Various embodiments of the means for coating the substrate and powering and controlling equipment of the coating apparatus are disclosed.Type: GrantFiled: January 8, 1999Date of Patent: May 14, 2002Assignee: FAStar, Ltd.Inventors: Gregory M.
