In some film-sticking fields with strict size requirements, the production quality requirements for PVC films are very strict. All PVC films need to be inspected on the surface before leaving the factory to detect whether there are stains on the surface of the PVC film. Most of the existing inspections are done manually or with manual auxiliary observation. However, since PVC films are generally long, manual inspection is time-consuming and inefficient, and the labor intensity is high for operators, making it difficult to meet production needs.
