The automation transformation used for the standard production line of smart factories can usually achieve a 15% to 40% increase in effective utilization rate per unit line, a 20% to 60% increase in direct production time efficiency, and a 5% to 15% decrease in core process defect rate. It is the core path for improving the efficiency of standardized production lines in smart factories.
1, The core support point for efficiency improvement
(1) Eliminating losses in manual processes
The time required for auxiliary processes such as loading and unloading, and mold changing has been reduced from 15% to 25% of the original manual standard production line to 3% to 8%, and the time for single batch mold changing has been shortened by 40% to 70%
Avoiding unplanned downtime caused by artificial fatigue and misoperation, reducing unplanned downtime by 20% to 50%
(2) Additional efficiency improvement of data closed-loop
When equipped with industrial sensors and PLC data acquisition modules, further efficiency space of 5% to 10% can be explored through process optimization
Realize millisecond level response to production line anomalies, reducing the processing time from 10-30 minutes for manual troubleshooting to 1-5 minutes
2, Applicable boundaries for efficiency improvement
Only suitable for standardized continuous production lines in smart factories, the improvement in customized multi variety and small batch production lines is only 5% to 10%
Require a production line rhythm of ≥ 1000 pieces/hour. If the rhythm is too low (<300 pieces/hour), the cost of automation transformation will offset the efficiency benefits
3, Data basis
The data is sourced from the "Guidelines for Efficiency Evaluation of Mechanical Manufacturing Automation Transformation" (industry standard) released in 2023
The sample covers 127 renovated standard production lines in key tracks of smart factories such as electronic assembly and automotive parts
