[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 One embodiment provided by this utility model:

[0027] The strip surface cleanliness testing device includes a fixed frame 3 and two mounting frames 7. Each mounting frame 7 has an adjustment mechanism 9 inside. The two adjustment mechanisms 9 include four first connecting pipes 901, two bidirectional lead screws 902, four second connecting pipes 903, four sliders 904, two motors 905, four cylinders 906, four one-way valves 907, four connecting blocks 908, and multiple air jet holes 909. The two motors 905 are externally fixedly mounted inside the two mounting frames 7 near the front end. The front ends of the two bidirectional lead screws 902 are fixedly mounted at the output ends of the two motors 905. The four sliders 904 are internally threaded to the outside of the two bidirectional lead screws 902. The four connecting blocks 908 are fixedly mounted on opposite sides of the four sliders 904, and externally slidably mounted inside the two mounting frames 7 near the upper end. On opposite sides, the output ends of four cylinders 906 are fixedly installed. The exterior of the four cylinders 906 is fixedly installed inside the upper part of two mounting brackets 7. The four one-way valves 907 are fixedly installed on opposite sides of the four cylinders 906. The input ends of four first connecting pipes 901 are fixedly installed inside the four cylinders 906. The output ends of four first connecting pipes 901 are fixedly installed on opposite sides of four first high-speed industrial cameras 10. The two ends of four second connecting pipes 903 are fixedly installed between the four first high-speed industrial cameras 10 and two second high-speed industrial cameras 11. Multiple jet holes 909 start on opposite sides of the four first high-speed industrial cameras 10 and two second high-speed industrial cameras 11. The upper ends of two mounting brackets 7 are fixedly installed with second high-speed industrial cameras 11. The upper ends of four sliders 904 are fixedly installed with first high-speed industrial cameras 10.

[0028] Specifically, when inspecting the surface cleanliness of cold-rolled strip steel, the activation of motor 905 causes the bidirectional lead screw 902 at its output end to rotate within the mounting frame 7. The rotation of the bidirectional lead screw 902 causes the threadedly connected slider 904 to move. This sliding movement causes the first high-speed industrial camera 10 to adjust its position on the upper end of the mounting frame 7, allowing the camera to adjust its position according to the width of the strip steel. This enables effective inspection of strip steel surfaces of different widths on the rotating roller 1. The first high-speed industrial camera 10 and the second high-speed industrial camera 11, through image processing technology, can identify defects on the strip steel surface and thus assess the surface cleanliness. Simultaneously, the movement of slider 904 also causes the connecting block 908 to move within the mounting frame 7. The connecting block 908 is connected to the output end of cylinder 906. Therefore, when the connecting block 904 moves, the connecting block 908 can move within the mounting frame 7. When block 908 moves, it drives cylinder 906 to extend and retract. When cylinder 906 retracts, it compresses the gas inside. One-way valve 907 ensures that the gas inside cylinder 906 can only flow from cylinder 906 to the jet holes 909 of the first high-speed industrial camera 10 and the second high-speed industrial camera 11, preventing reverse flow. This allows the gas to be forced into the jet holes 909 on one side of the first high-speed industrial camera 10 and the second high-speed industrial camera 11 through the first connecting pipe 901 and the second connecting pipe 903, and finally ejected through the jet holes 909. This ejected airflow will directly blow onto the camera lens surface, sweeping away the dust and impurities attached to the camera lens surface, thereby improving the quality of the captured image. This not only improves the accuracy and efficiency of detection, but also provides a reliable foundation for subsequent data processing and analysis, further ensuring the quality and safety of strip steel production.

[0029] Reference Figure 1 , Figure 2 and Figure 3 The upper ends of the two mounting brackets 7 are slidably equipped with protective covers 2. The two mounting brackets 7 are fixedly equipped with lighting lamps 8 on opposite sides. The fixed bracket 3 is equipped with two rotating rollers 1. The lower ends of the two mounting brackets 7 are equipped with four universal wheels 6. The lower ends of the two mounting brackets 7 are threadedly connected with four threaded sleeves 5. The lower ends of the eight threaded sleeves 5 are fixedly equipped with support pads 4.

[0030] Specifically, the casters 6 at the bottom of the mounting bracket 7 facilitate movement, the threaded sleeve 5 and the support pad 4 ensure the stability of the device during the inspection process, thus facilitating the arrangement and maintenance of the device, the lighting lamp 8 provides sufficient illumination for the inspection camera to ensure image quality, and the protective cover 2 not only protects the camera and other key components from damage, but also reduces the impact of external light sources on the inspection and improves the accuracy of the inspection.

[0031] Working Principle: In use, first move the universal wheels 6 to the sides of the fixed frame 3. Then, rotate the threaded sleeve 5 to make the support pad 4 contact the ground. After fixing the position of the mounting frame 7, activate the motor 905 inside the mounting frame 7 to drive the bidirectional lead screw 902 to rotate inside the mounting frame 7. The rotation of the bidirectional lead screw 902 will cause the slider 904, which is threaded to it, to move. When the slider 904 moves, it will move the first high-speed industrial camera 10 on the upper end of the mounting frame 7, thereby adjusting the position of the first high-speed industrial camera 10 to detect the surface of strip steel of different widths. At the same time, the slider 904 will also drive the connecting block 908 on the mounting frame 7. When internal movement occurs, since the connecting block 908 is connected to the output end of the cylinder 906, the movement of the connecting block 908 will drive the cylinder 906 to extend and retract. When the cylinder 906 retracts, the gas inside it enters the first high-speed industrial camera 10 and the second industrial camera through the first connecting pipe 901 and the second connecting pipe 903, and is ejected from the jet hole 909 on the side of the camera. The airflow directly blows away the dust and impurities on the surface of the camera lens, thereby improving the quality of the captured image. Then, the protective cover 2 is slid to block the external light source, reducing the impact of the external light source on the shooting quality. Subsequently, the lighting lamp 8 is turned on to provide a stable and uniform lighting environment for the camera, further ensuring the shooting quality.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
