ONLINE MEASUREMENT SYSTEM FOR SURFACE CLEANLINESS OF COLD-ROLLED STRIP STEEL

WIPO Patent Application WO/2023/151249

A1

An online measurement system for surface cleanliness of cold-rolled strip steel, comprising a stable roller (C1), strip steel (C2), a shielding box body (C3), a light source (C4), a lens (C5), a camera (C6), a network cable (C7), a data collection card (C8), an image processing server display (C9), and cleanliness online measurement software (C10), wherein the stable roller (C1) forms a certain wrap angle in a photographing region to inhibit vibration of the strip steel (C2); the shielding box body (C3) is used for shielding the influence of ambient light on a system light path; the lens (C5) is mounted on the camera (C6) by means of an interface; the camera (C6) and the data collection card (C8) are connected by means of the network cable (C7); the data collection card (C8) is mounted on a PCI slot of the image processing server display (C9); and the cleanliness online measurement software (C10) runs on the image processing server display (C9). The certain wrap angle is formed in the photographing region by means of the stable roller (C1) to inhibit the vibration of the strip steel (C2), so that the imaging quality of an image is clear; the influence of the ambient light on a system is shielded by means of the shielding box body (C3), so that the interference of the ambient light is small; and for the specification change of the strip steel (C2), the imaging quality is recognized and a camera (C6) position adjustment mechanism is controlled to move until the imaging quality is clear, and thus, the application range is wide.
