These devices play a crucial role in the microelectronic manufacturing process, ensuring product quality and reliability. Depending on specific product and production needs, appropriate detection equipment or combination of multiple devices can be selected to achieve efficient and accurate quality control. Currently, FPC circuit strips are mostly detected by cameras, and their surfaces are detected by images. The collected images are preprocessed in the background, such as denoising and contrast enhancement, to improve image quality. Then, image processing algorithms are used to analyze the images and identify various defects on the FPC surface, such as scratches, stains, bubbles, and pad oxidation. However, after detection, the FPC circuit strip needs to be rolled up for easy storage. Detection personnel cannot intuitively understand the specific appearance defects of the FPC circuit strip, and workers need to carefully observe it with their naked eyes, which reduces the problem handling efficiency of subsequent detection personnel. Therefore, improvement is needed. SUMMARY
