Introduction: The Limits of Manual Inspection
As cylindrical battery production scales to meet market demand, quality control for the positive electrode remains pivotal. This inspection is challenging because phút defects on reflective, curved surfaces are difficult to detect at cao tốc độ sản xuất.
For many manufacturers, manual inspection has traditionally been the default approach. But human eyes—no matter how trained—fatigue over time. This leads to “traceability gaps” where missed faults slip through, elevating the risks of short circuits, thermal runaway, and costly warranty claims. Furthermore, as cycle times tighten, manual labor simply cannot keep up.
The goal of this project was straightforward but ambitious: Replace manual labor with a fully automated system that improves quality standards while delivering a tangible Return on Investment (ROI).
The Challenge: Tiny Defects on Shiny Surfaces
The project required detecting minute defects on the reflective metal cap of the battery. The specific challenges included:
- Complex Defect Types: The system needed to identify everything from structural biến dạng và missing welds to microscopic laser welding pinholes và tách lớp.
- Yêu cầu tốc độ cao: The target cycle time was extremely aggressive to match production throughput.
- Thích ứng với văn hoá: The line produces 4 different compatible types of batteries, requiring a system that can handle changeovers without complex reconfiguration.
The Solution: Scalable AI Inspection
UnitX deployed a multi-station vision solution capable of inspecting batches of 8 pin một lần.
- Fly-Capture Technology: The system utilizes fly-capture imaging at a speed of 40mm / s, allowing it to snap high-resolution images without stopping the movement of the battery tray.
- Hiệu quả phần cứng: Powered by a lean setup of one UnitX OptiX imaging system and Bộ não AI processing units, the system is scalable across multiple stations.
- Nhận dạng lỗi: The AI was trained to see through the reflection, identifying issues like “Edge exposed welding” and “Poor edge welding” that often look like normal lighting variations to standard cameras.
Speed, Safety, and Savings
The deployment of this automated system delivered immediate, quantifiable business results.
1.High ROI: Labor Cost Reduction
Automation isn’t just about technology; it’s about economics.
- Hiệu quả của lực lượng lao động: 2 QC staff were reduced immediately following deployment.
By automating this difficult task, the manufacturer reallocated human resources to higher-value tasks, significantly lowering operational costs.
2.Unmatched Speed
The system is incredibly fast, processing batteries faster than the blink of an eye.
- Vision Cycle Time: 0.25 giây cho mỗi phần.
- Overall Machine Cycle Time: 0.9 giây cho mỗi phần.
3.Superior Quality Control
The system exceeded its original targets for accuracy.
- Ý nghĩa: nhận được gì critical defects leaked to the customer.
- Ý nghĩa: Với một FR ≤ 1%, the system is highly precise, wasting far less material than the previous manual or semi-automated methods.
Kết luận
This case study demonstrates that replacing manual inspection with AI is not just a safety upgrade—it is a smart financial move. With a vision cycle time of 0.25s và 0% escape rate for defects, UnitX provides the reliability that the battery industry demands, while delivering the efficiency that the bottom line requires.
