The automation transformation of SIS safety instrument production line can improve the production efficiency of a single batch by 30% -55%, reduce the rework rate of non-conforming products by 20% -35%, and meet the process data traceability requirements of IEC 61508 SIL level. 1, Specific dimensions of efficiency improvement (1) Optimization of single process cycle time
Replacing manual calibration of instrument ranges and repetitive operations such as circuit switching, the production cycle of a single unit has been reduced from 15-20 minutes to 8-12 minutes, and the production cycle of a single batch (100 units) has been shortened by more than 40%. (2) Improvement of quality control efficiency
Automatically complete data collection, comparison, and abnormal warning. The accuracy of detecting non-conforming products has increased from 85% manually to 99%, and the rework rate has been reduced by 20% -35%;
Avoiding manual recording errors, achieving 100% traceability of process data, and reducing downtime caused by data supplementation and verification delays. 2, Efficiency improvement boundary of transformation
If the existing production line already has basic automation components such as PLC and sensors, the transformation has a higher input-output ratio, and the efficiency improvement can approach the upper limit of 55%;
If it is a purely manual production line, additional equipment integration and communication transformation are required, resulting in an efficiency improvement of about 30%.
