Research on mistake proofing technology for airbag flexible assembly line based on barcode and database

As an automobile product, the reliability and accuracy of the assembly process must be ensured. In order to achieve the minimum errors in the assembly process, a new assembly control approach which combines the technology of station computer, barcode scanner and specialized assembly and detection components was proposed. Based on the existing theories of mistake proofing, the article will briefly introduce the work flow of designing and implementing a new mistake proofing algorithm. The algorithm is implemented in the environment of SQL database and Visual Basic 6.0. Furthermore, as the real applications demonstrate, due to the processing mechanism of client-server model, the system enjoys the advantages of complete mistake proofing and fast reaction, which makes it suitable to be applied in the flexible manual or automatic assembly lines that have huge variety of products and requires a lot in the quality monitoring.
