Abstract

A panel of flexible xerographic photoconductor is ultrasonically welded into a belt shape, while the two abutting ends of the panel are held in a vacuum chuck fixture. A top view of the fixture is shown. The portions 10, 11, 12 and 13 of the fixture are coplanar. Portions 11 and 12 are porous and comprise a vacuum chuck against which the non-coated side of the photoconductor's substrate is securely held during welding. L-shaped guide blocks 14, 15, 16 and 17 facilitate locating the ends of the panel in an accurate fashion prior to welding. The distance 18 between the guide blocks is accurately controlled to be equal to the width of the photoconductor panel. A flat metal guide plate 19 is used to locate the ends of the photoconductor panel on the fixture.

Photoconductor Belt-Welding Fixture

A panel of flexible xerographic photoconductor is ultrasonically welded into a belt shape, while the two abutting ends of the panel are held in a vacuum chuck fixture. A top view of the fixture is shown. The portions 10, 11, 12 and 13 of the fixture are coplanar. Portions 11 and 12 are porous and comprise a vacuum chuck against which the non-coated side of the photoconductor's substrate is securely held during welding. L-shaped guide blocks 14, 15, 16 and 17 facilitate locating the ends of the panel in an accurate fashion prior to welding. The distance 18 between the guide blocks is accurately controlled to be equal to the width of the photoconductor panel. A flat metal guide plate 19 is used to locate the ends of the photoconductor panel on the fixture. The two end portions 20 and 21 of this guide plate mate with the L-shaped guide blocks. As the first step in this process, guide plate 19 is positioned to cover the flat portion 12-13 of the fixture. One end of the photoconductor panel is now placed on portion 10-11, with the edge of the panel abutting the straight surface 30 of the guide plate. Vacuum chuck 11 is then activated. The guide plate is now removed, and placed on top of the photocon ductor panel end which is now vacuum held on portion 10-11. The L- shaped guide blocks are accurately located so that a small sliver of photoconductor now extends out from under the portion 30 of the guide plate. The other end of the pho...
