Ensure traceability of gasoline pumps using direct part marking (DPM)
Read and inspect integrity of DPM codes at each check point in the production line
Verify every pump is marked with two different DPM codes and check position of codes
Automatically enter DPM details into database
Meet "zero non-read" requirement, meaning no part can get through as not having been read
Achieved 100% read rate of DPM codes, avoiding manual intervention and contamination of “white room” environment
Integrated accurate traceability throughout entire operations, ensuring manufacturing process is controlled, inspected, and recorded from start to finish
Increased client confidence by proving each part is completely traceable and has been correctly inspected
Nell'ambito della produzione di pompe per benzina, Siemens doveva garantire che ogni prodotto fosse contrassegnato da due codici diversi. Occorreva verificare la posizione dei codici e garantirne una lettura adeguata, in modo da confermare che ogni singolo componente fosse dotato di contrassegno adeguato e fosse verificato tramite un database in corrispondenza dei vari punti di verifica sulla linea produttiva. Siemens ha scelto di garantire questa rintracciabilità tramite codici DPM (Direct Part Marking) posti sulla struttura di ogni pompa. L'intera linea produttiva è dotata di sistemi di visione In-Sight® di Cognex che garantiscono la lettura e l'ispezione di codici DPM in corrispondenza di ogni punto di ispezione.
