This invention relates to the fields of signal transmission, computer vision, image recognition, and printing. It provides a visual inspection method, system, and mobile phone casing for screen printing processes. The method uses a screen printing image recognition algorithm to identify the aperture spacing and mesh size of the screen printing stencil. When the aperture spacing and mesh size are compliant, it prompts the assembly of a compliant screen printing stencil to the printing press for printing the base color layer of the substrate. The substrate, after being left to stand and bake, is then transported to a CCD inspection line for CCD imaging. The system checks for jagged edges, smearing, and light leaks in the characters of the ink-printed layer on the substrate, and determines whether the brightness of the ink in the ink-printed layer is compliant. This improves the efficiency and accuracy of detecting the specifications, serial numbers, aperture spacing, and mesh size of the screen printing stencil, and enhances the efficiency and accuracy of detecting jagged edges, smearing, and light leaks in the characters of the ink-printed layer on the substrate, as well as whether the ink brightness meets requirements, thereby achieving high-quality mobile phone casing production.
