Project Name: AI Inspection of Inner Wall Defects of Hybrid Engine Cylinder Block Oil Passage & Laser Marking Traceability
2025-10-17
Project outcome
Cycle time: 4.5 seconds per piece (800 pieces per shift)
Inspection failure rate ≤ 0.1%, error rate ≤ 0.5%
Save 2 quality inspection staff + 1 marking staff, ROI within 8 months
Project Background
The oil passage is 180 mm deep. The manual endoscope inspection takes 3 minutes per piece, with a missed detection rate of 8%.
Key technologies:
Eston inverted SCARA equipped with Hikvision 2K high-speed internal camera module + 360° surround-view lens
The Sirena platform enables one-click switching among 8 models, and the API directly drives Eston to complete the "taking photos - inspection - marking - sorting" four-in-one process
The Hikvision defect model is based on 120,000 internal wall samples and can identify 0.2 mm cracks, sand holes, and residual sand.
