Introduction: The Pressure is On
Trong ngành công nghiệp ô tô, Bơm nhà ở is a component that lives under stress. Whether for oil, water, or fuel, these housings must withstand high pressures and maintain perfect seals.
Defects that might look minor on the surface—like porosity (tiny air pockets in the metal), material loss, or peeling—can become stress concentration points. Under operating pressure, these flaws can cause the housing to crack, leading to catastrophic leaks and engine failure.
Traditionally, inspecting these complex, machined metal parts (approx. 60x60x70mm) was a manual process. However, manual inspection struggles to spot “incomplete machining” or subtle “color variations” consistently across thousands of shiny, complex 3D parts.
The Challenge: Complex Defects on 3D Geometry
The goal was to replace manual labor with a fully automated, AI-driven system. The inspection requirements were extensive, covering both casting and machining flaws:
- Lỗ hổng bề mặt: Scratches, pits, dents, and color variations.
- Tính toàn vẹn của vật liệu: Porosity (a critical casting defect) and peeling.
- Lỗi gia công: Material loss and incomplete machining.
Crucially, the client required a system with Remote Update Modules, ensuring that as new defect types appeared or product designs changed, the AI-driven system could be updated without a site visit.

The Solution: A 4-Station Servo Conveyor Line
Để đảm bảo toàn diện Bảo hiểm 360 độ, UnitX implemented a multi-stage inspection line integrated with a high-precision servo conveyor. By advancing the part through four distinct inspection stations, the system meticulously captures every angle and complex surface of the 3D geometry, leaving no room for ‘blind spots”.
UnitX’s 4-station inspection line, featuring automated diverting for OK and NG parts
Intelligent Sorting Logic:
- Phân tích thời gian thực: As the part moves, the UnitX Bộ não analyzes images instantly.
- Automated Diverting:
- OK Parts: Automatically directed to the pallet for shipping.
- NG (No Good) Parts: Instantly diverted for rework or scrap.
Sức mạnh phần cứng:
- hình ảnh: 4x UnitX OptiX systems provide comprehensive coverage of the housing’s multiple faces.
- tính toán: Một chuyên dụng CorteX AI Central và Inspection Cell handle the heavy lifting of processing millimeter-scale defects in real-time.
Results: Achieving Zero-Tolerance in Automotive Quality Assurance
UnitX deployment sets a new standard for reliability, combining high-speed processing with an uncompromising stance on safety.
- Zero Escape: We’ve achieved a 0% False Acceptance Rate for safety-critical defects. By providing total containment for porosity and micro-cracks, the system ensures “zero-leak” reliability, shielding manufacturers from the liabilities of catastrophic part failure.
- Precision-Balanced Yield: Quality shouldn’t come at the cost of high scrap rates. With an overall False Acceptance of ≤ 0.5% for cosmetic flaws and a False Rejection Rate of ≤ 5%, the AI-driven system accurately differentiates between true defects and harmless variations to maximize ROI.
- Synchronized Throughput: Eliminate production bottlenecks. The system performs a comprehensive 3D analysis of complex geometries within a 5-second cycle time, cho phép Phạm vi kiểm tra 100% without slowing down high-volume production lines.
