AI Technical Summary
Existing technologies struggle to perform blind-zone-free, high-efficiency, and automated surface defect detection on the circumferential and end faces of cylindrical lithium batteries. Furthermore, the lack of deep coupling between the detection algorithm and the hardware acquisition path leads to low detection efficiency and inconsistent results.
Using V-groove roller friction drive and linear motor material feeding, the rollers are rotated synchronously by stepper motor control. Combined with multi-camera synchronous triggering and pixel strip stitching, a distortion-free cylindrical surface unfolding image is generated, and the entire battery pack is efficiently and automatically detected and sorted.
It achieves blind-zone-free, high-efficiency detection of cylindrical lithium battery surfaces, ensuring consistent test results and efficient operation of automated processes, thereby improving detection efficiency and accuracy.
