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.
