Abstract:
Apparatus providing for automatic manufacture of a portion of an electron gun in a cathode ray tube utilizes two conjointly operated indexing tables with an intermediate transfer mechanism to assemble, fit, stake and weld in place a series of parts. At a series of indexing positions parts are loaded, checked and processed with such manufacturing steps as cutting, positioning and welding a lead tab to a cathode cylinder. The use of two tables permits high strength for staking operations, greater production in a given time, and accessible layout of equipment in a small space.
Abstract:
A jig is arranged with a cylindrical metallic post for receiving a cylindrical CRT electrode snugly thereover arranged adjacent a pair of separated shaped insulating mounts with protruding fingers above a rest platform for engaging the ends of and confining a mounting strap with a cylindrical section conforming to the outer surface of the cup electrode, so that the strap is held in place adjacent the cylindrical electrode in a loosely fitting arrangement into which a welding head may be moved into the cylindrical section between said fingers to push the strap closely adjacent the cylinder and weld it thereto.
