Abstract:
1. A computer implemented method for mistake-proofing an assembly process comprising the steps of: introducing a base part into a workstation; identifying the base part to a system; using the ID information to retrieve and display all assembly specific information necessary for an operator to begin working on an assembly ranked according to assembly sequence; sending BOM part bin location information to a PLC for the specifically identified assembly; using the PLC to activate appropriate parts bin indicators; determining if assembly tools are interfaced to the system for the particular assembly identified and indicating such to the operator at a workstation terminal; using the PLC to trigger appropriate ladder logic according to the assembly program for the particular assembly identified; using the PLC to activate the proper interfaces for parts indicators, orientation, tool usage inputs, add bin sensors as required; beginning work on the assembly according to the sequence displayed at the workstation terminal; using the PLC to send a message to the system that an assembly sequence has been completed; determining whether all ranked assembly steps have been completed; if all ranked assembly steps have not been completed repeating the sequence for the next ranked assembly sequence; and, sending a message to the PLC to release the assembly for position advance.
