An automated data collection system using bar code technology was developed to aid automated inspection within an assembly cell. This system was designed to identify extra or missing components in a low volume, high variety mix of assembled products. Before leaving the assembly cell, a bar code on the assembled and packed product is scanned for its specific product identification number. The identification number serves as a key to a database lookup table of established weight tolerances for the product. The product is then weighed with an electronic scale and its weight is compared to pre-established tolerances. The operator is informed of the outcome of this comparison, and is prompted for specific feedback on failed outcomes. The system was piloted in a cell which assembles handle mechanisms for molded case circuit breakers. Results showed that the system reduced the defect rate from 1978 ppm to less than 67 ppm.
