An Edge-AI QC Retrofit: One Production Line’s Record
A hardware-parts factory replaced manual visual inspection. The numbers deserve a full replay.
Before
- Six inspectors on two shifts, 3-5% miss rate, high turnover;
- Customer complaints centered on missed scratches.
The retrofit
- Hardware: RK3588 industrial unit + two 5 MP cameras + ring light;
- Model: defect classes (scratch/dent/burr) + OK/NG verdict at 28 fps on NPU;
- Actuation: pneumatic ejection of NG parts, MES traceability.
Results
- Miss rate down to 0.3%, consistency 100%;
- Total investment ~30,000 RMB, paid back in 8 months;
- Inspectors moved to model labeling and maintenance.
The key to edge-AI adoption isn’t algorithm sophistication — it’s “retrofit cost < six months of labor".
