Abstract

This article describes a method of testing completed products in high volumes. Computer terminals are shipped as separate elements, for "Customer Set-up" after they arrive in the customer's office. All video elements must work with any logic element, and early-life failures must be eliminated. For these purposes, we perform a "Merge Verification" by applying power to the merged product and running diagnostic routines for a number of hours. Logistics problems result for high volume production.

Automated Merge Verification of Computer Terminals

This article describes a method of testing completed products in high volumes. Computer terminals are shipped as separate elements, for "Customer Set-up" after they arrive in the customer's office. All video elements must work with any logic element, and early-life failures must be eliminated. For these purposes, we perform a "Merge Verification" by applying power to the merged product and running diagnostic routines for a number of hours. Logistics problems result for high volume production.

In the system described herein: heavy merged terminals (boxes) are handled easily; electrical power is available for testing; all boxes may be checked periodically; elapsed time to failure can be recorded; no box can bypass this system; operator lifting or guidance is not required; the operator can vary test duration.

A powered conveyor system is used as the Merge Verification Facility. The conveyor is arranged in multiple levels, with several lines or spurs on each level. Elevators are used to move terminals from level to level. Each spur moves boxes unidirectionally. Power outlets are installed along the length of each spur. Loading and unloading happen simultaneously for one spur at a time. Each spur becomes active to reload in a set and unchanging rotating order. Completed boxes roll out of the Merge Verification Facility on to the final test facility, while newly built untested boxes roll in behind them. When the new boxes ar...
