Detect Missing O-rings

100% accurate O-ring presence detection at production speed. Catch assembly errors before they ship.

The Challenge

Manual O-ring verification is slow, inconsistent, and expensive. Missing O-rings in the field cause product failures and customer returns.

01
Manual labour bottleneck
Operators must visually inspect every assembly, slowing line throughput and introducing human error.
02
Inconsistent quality
Operator fatigue and distraction cause missed defects. AQL sampling misses critical failures.
03
Field failures & returns
Missing O-rings leak into the field, causing customer returns, warranty claims, and reputation damage.
04
High rework costs
Catching failures late means expensive disassembly, rework, and logistics costs.

How AI O-ring Detection Works

100% inline inspection

Mounted at assembly checkpoint — real-time verification as parts move down the line

AI detects presence & seating — identifies missing, misaligned, or unseated O-rings

Zero downtime to line speed — processes at 100+ parts/minute

Instant alerts — operator notified immediately, line stops for correction

Real-World Example

Medical Device Assembly Plant (Italy)

“We were shipping ~5-8 defective units per week due to missed O-rings. After deploying Logirobotix, zero escapes in 6 months. The ROI paid for the system in month two.”

Frequently Asked Questions

Another question? Call us on +39 049 825 6850 or email info@logirobotix.com.

How accurate is O-ring detection?

Detection accuracy consistently exceeds 99.5% in production environments. The AI distinguishes between present/absent, properly seated/unseated, and correct position/misaligned O-rings. Accuracy improves over time as the model learns your specific assembly and lighting conditions.

Do I need to change my production line?

No. The camera mounts at the existing inspection point without disrupting line flow. Integration takes 1-2 hours. Most customers report zero workflow changes.

What if my O-rings are different colours or materials?

The AI trains on your specific O-ring type, material, and assembly. Whether your O-rings are black, red, white, silicone, or EPDM, the system learns to detect them reliably. We include this in the free POC.

Can it work at high line speeds?

Yes. The system is designed for 100+ parts/minute. For ultra-high speeds (>300/min), we may recommend additional cameras or a faster processing module — we assess this during the free POC.

What’s the cost?

The Quality Control plan starts at €1,800/month and includes hardware, AI software, installation, and support. Most customers save €6-12k/month in reduced scrap and rework, achieving payback in month two.
