[0002] In the face of the ever-increasing product quality requirements of users of automotive steel and home appliance plates and the market competition, it is particularly important to ensure that quality inspectors can quickly and accurately detect quality defects on the surface of the strip at the quality inspection stations of each cold rolling unit. At present, the quality inspection stations of each cold rolling unit at home and abroad are generally divided into vertical quality inspection stations and horizontal quality inspection stations to achieve the quality inspection of the upper and lower surfaces of the strip. Figure 1 Among them, the vertical quality inspection table manually completes the quality inspection of the upper and lower surfaces of the strip through visual inspection. The vertical quality inspection table is often either too short or too high, which has an adverse impact on the quality inspection personnel's work in checking the surface defects of the strip while the unit is running. It often leads to missed defects or defects running through the vertical quality inspection table. After the defect runs through the vertical quality inspection table, it is rechecked through the quality inspection instrument (i.e., surface inspection instrument) on the surface of the unit to confirm the location of the defect. However, the returned steel strip increases the occurrence of new defects such as scratches and dents, which causes the loss of finished product production, reduces the yield rate, increases production costs, and weakens the survival vitality of steel companies in the fierce competition in the industry.

[0027] [Example 1]

[0028] Strip quality inspection is carried out in the vertical quality inspection area of ​​the quality inspection table of each cold rolling unit. When the unit is running, the surface defects of the strip are inspected. Figure 1 After checking the steel strip from the vertical quality inspection area, the machine is slowed down, stopped, or the defects are missed and then stopped and slowed down again. Then the defects are reviewed through the surface quality inspection instrument on the operating table next to the machine. This is time-consuming and has a cumbersome work rhythm. A strip surface quality inspection device and method, see Figure 2 ,See Figure 3 , helping quality inspectors to identify the locations of quality defects during unit operation and make decisions immediately.

Steering rollers 3 (3) and 4 (4) are each equipped with a top surface inspection instrument measuring head (301) and a bottom surface inspection instrument measuring head (401), located adjacent to each other. These instruments measure the strip's surface quality defects in real time and upload images of the strip's defect characteristics to the surface quality inspection instrument system (702) on the central console (7). The vertical quality inspection platform (6) features top and bottom surface stroboscope lamps (601 and 602) for inspecting the strip's top and bottom surfaces. Display screens 1 (605) and 2 (603) are located on either side of the steel structure columns of the vertical quality inspection platform (6), near the strip, allowing quality inspectors to quickly and in real time check the strip's surface quality. To facilitate prompting quality inspectors on the timeliness of quality inspections, a client (701) has been added to train the defect expert database and review defects in the surface inspection instrument defect expert system. Real-time images of strip surface quality defects, collected from the on-site upper / lower surface inspection instrument's measuring heads 301 / 401, are displayed on split screens on display screen 1 605 and display screen 2 603 via the client host 701 operating system software. These images are then used by quality inspectors for real-time assessment, thereby improving the efficiency of online surface quality inspections. The upper surface-side control panel 606 and the lower surface-side control panel 604 both feature buttons for quick stop, acceleration, and stop. These panels are fixed to the steel structure columns of the vertical quality inspection platform 6, reducing the frequency of inspection stops and mitigating new quality defects caused by strip drooping due to frequent inspection stops.
