High-speed vision challenge for 100% online on-Strip inspection

The paper presents the challenges of effective high-speed detection for screen out incomplete fill (IF) reject via online Vision System at Trim/Form process. In general, most of the assembly factories screen the incomplete fill reject manually or through a vision on Test Handler. The speed of this Unit by Unit inspection is very low. Usually, the effective UPH is less than 30k. Accordingly, a new idea of online Strip by Strip inspection is bring out. By this way, total 36 units (or even more) can be detected every step. And the inspection UPH can reach to more than 500k. To achieve this target, the biggest challenge comes from that large image data/information need to be processed in tens of microseconds. As presented in this paper, based on advanced algorithms, excellent program structure and optimized hardware composition, the system can realize 100% online unit inspection with only 1 camera at a Trim/Form machine. The speed of this vision can freely match with any high-speed running Trim/Form machine, which will gain competitive advantages.
