ABSTRACT:
A production system is disclosed for registering flat tension masks to screen bearing face panels in the manufacture of cathode ray tubes. Both the panel and mask are supported in modules with identical registration features at loading stations and alternately conveyed to an assembly station with a top mounted laser welder for welding the mask to panel rails. A lift assembly up loads the modules into the assembly station where they are registered with the same registration elements. Screen location on the panel is interrogated by panel module associated cameras that view spaced fiducial marks on the panel previously located with respect to the screen. Mask interrogation is also accomplished by a camera array. Early screen interrogation enables the mask to be preliminarily positioned very close to final positioning.
