How much does the automation transformation of SMT surface mount production line help improve production efficiency

After the automation transformation of SMT surface mount production line, the comprehensive production efficiency has been improved by 30% -80%, depending on the automation foundation of the original production line, the coverage of the transformation process, and the product characteristics.
1, Quantitative range for efficiency improvement
(1) Transforming the fully manual production line into a semi automated/fully automated production line: increasing efficiency by 60% -80%, with the core being to replace manual feeding, connection, and testing processes, reducing the stagnation and errors of manual operations.
(2) There are already semi-automatic production lines (including surface mount machines and reflow soldering) that have completed automated connection/loading/AOI testing: efficiency has been improved by 30% -50%, mainly solving the bottleneck of manual connection of production line breakpoints.
2, The core path of efficiency improvement
Reduce changeover time: Automated feeding rack+intelligent program call, the changeover time has been reduced from 15-30 minutes/time manually to 2-5 minutes/time.
Reduce stagnation losses: The transformation of production line interconnection eliminates the downtime caused by manual handling and waiting for materials, reducing the proportion of downtime from 10% -15% of the original manual production line to 2% -5%.
Reduce repair losses: The precision error of automated mounting is controlled within ± 0.02mm, reducing the defect rate of mounting by more than 80% compared to manual mounting, indirectly improving effective output.
3, Key factors limiting the extent of improvement
Product features: In the scenario of multi variety and small batch production, the frequency of automated changeover is high, and the improvement rate will be 15% -20% lower than that of large batch single variety.
Equipment adaptability: Old surface mount machines cannot be compatible with new automated feeding/testing equipment, and core hardware needs to be upgraded synchronously, otherwise the ideal improvement value cannot be achieved.
