Introduction: The Complexity of the Cap
In Lithium-ion cell production, the トップキャップ is not just a lid; it is a complex assembly of safety features. It contains the explosion-proof vent, the electrode poles, and critical seal points.
Because of this complexity, the variety of things that can go wrong is staggering. From weld breaks and membrane misalignment to oxidation and simple scratches, the defect list is massive. For human inspectors, memorizing and spotting over 100 different defect types across various materials and product sizes is a cognitive overload. This leads to fatigue, missed defects, and ultimately, end-customer complaints.
The challenge for this project was not just “automation,” but “versatility.” The client needed a system that could handle extreme defect variety and diverse materials, and they needed it fast.
The Challenge: 100+ Defects, One Failing Solution
The scope of this project was daunting and it aimed to replace the traditional “one solution”—manual inspection—which had reached its breaking point. The vision system needed to reliably identify over 100 distinct types of defects、を含みます：
- Welding Issues: Breaks, voids, pinholes, and discontinuity.
- コンポーネント障害: Explosion-proof vent deformation, membrane misalignment.
- 表面の欠陥: Oxidation, scorching, burn marks, and physical damage.
Furthermore, the production line handles diverse materials and product sizes, meaning the system couldn’t be a “one-trick pony.” It had to adapt to different reflective properties and geometries without constant re-tuning.

The Solution: A Robust, AI-Driven Vision Platform
UnitX delivered a high-performance inspection station engineered to “digest” extreme complexity at line speed.

System Power: Precision Engineering Meets Neural Intelligence.
- Multi-Angle Imaging (OptiX): The station utilizes a proprietary OptiX configuration designed for total visibility. The multi-camera array is set at strategic angles to provide comprehensive coverage of the part’s entire geometry. This setup clearly identifies structural flaws—such as vent deformations and pinholes—from multiple perspectives.
- AI Central Processing (CorteX): The “brain” of the system is the UnitX CorteX deep learning engine. CorteX is engineered to navigate the nuances of top-cap production, empowering it to distinguish between critical failures and harmless environmental variables. It ensures a “burn mark” is never confused with a shadow, and oxidation is never mistaken for a material reflection.
Results: Speed in Deployment, Savings in Labor
The results of this deployment highlight not just technical capability, but operational agility.
1. Rapid Deployment (2 Weeks)
Industrial automation projects often drag on for months.
- 結果： Full line deployment and customer acceptance in just 2 weeks.
- The pre-trained capabilities of the UnitX AI platform allowed for an incredibly fast integration, minimizing downtime for the manufacturer.
2. High ROI: 66% Labor Reduction
The system didn’t just assist inspectors; it replaced the need for a large team.
- 前： 6 quality inspection personnel per shift.
- 後： 2 personnel per shift.
- This reduction from 6 to 2 represents a massive saving in operational costs, delivering a rapid Return on Investment (ROI).
3。 品質保証
- False Acceptance Rate (FA): 0%.
- False Rejection Rate (FR): ≤5％.
- 影響： The client reported a confirmed decrease in end-customer complaints following the installation, proving that the machine was catching defects that human inspectors were missing.
