Abstract
The method of assembling a CRT includes (1) providing at least one envelope part having a unique, optically machine-readable, process-survivable coded marking on an external surface thereof, (2) optically machine-reading the marking, (3) generating a signal in response to step (2), (4) in response to the signal, initiating a local process for action with respect to the envelope part and (5) recording data of the local process with reference to said coded marking. The action may include transportation of the part, assembly of other parts or subassemblies to the part, or testing of an assembly including the part.
Claims8
In a method of assembling a series of CRTs, each said CRT comprising a plurality of parts assembled with respect to one another, each said CRT including at least one glass envelope part, the steps comprising
- (1) advancing a series of said at least one glass envelope parts,
- (2) producing in each said parts a unique, optically machine-readable process-survivable coded marking on the external surface thereof,
- (3) optically machine-reading each said coded marking,
- (4) generating a control signal related to each said coded marking in response to step (3),
- (5) in response to each signal, initiating a local process for action with respect to said envelope part and
- (6) recording data of said local process with reference to each said coded marking.
