[0002] Automotive fluid control valves are devices used to control the flow direction, pressure, and flow of fluids (such as fuel, lubricating oil, coolant, brake fluid, etc.) in automotive systems. They achieve precise control of the fluid by opening, closing, or adjusting the opening of the valve, thereby meeting the working requirements of different automotive systems.

[0003] Image-based roundness detection devices for automotive fluid control valves typically include a high-resolution camera, lens, and light source system to ensure the acquisition of clear and accurate valve images, extract the valve image contour, and calculate the roundness, thereby deriving the valve roundness parameters. Most existing technologies use manual handheld camera modules for image acquisition. However, workers are prone to fatigue during long periods of image acquisition, which may lead to decreased recognition accuracy and increased error rates. Fatigue not only affects work efficiency but may also have a negative impact on image recognition accuracy. Utility Model Content

The automobile fluid valve to be tested can be placed on the placement table 2. The image acquisition mechanism 4 can drive the image collector 5 to perform circular motion along the surface of the column 1. The mounting ring 401 and the support ring 402 in the image acquisition mechanism 4 both play the role of support and connection. The drive motor 405 is activated to drive the gear 406 to rotate. Since the teeth of the gear 406 and the surface of the gear block 407 are engaged with each other, the gear 406 can drive the moving platform 404 to slide in a circle along the track 403 when it rotates, thereby driving the image collector 5 to automatically collect the automobile fluid valve through the image acquisition mechanism 4, thereby improving stability and ensuring efficiency.

[0025] Reference Figure 2 One side of the mounting ring 401 is fixedly connected to the first connecting seat 6, the inner cavity of the first connecting seat 6 is rotatably connected to the connecting rod 7, one end of the connecting rod 7 is rotatably connected to the second connecting seat 8, one side of the second connecting seat 8 is fixedly connected to the fixing plate 9, one side of the fixing plate 9 is fixedly connected to the surface of the column 1, by setting the first connecting seat 6, the connecting rod 7 and the second connecting seat 8, the first connecting seat 6, the connecting rod 7 and the second connecting seat 8 can adjust the support angle of the fixing plate 9, thereby increasing the support strength and ensuring the stability of the image acquisition mechanism 4.

[0026] Reference Figure 2 and Figure 4 An extension plate 10 is fixedly connected to one side of the movable platform 404, and a fixed seat 11 is fixedly connected to one side of the extension plate 10. The fixed seat 11 is mainly used for the installation of the image collector 5 through the setting of the extension plate 10. The extension plate 10 facilitates the adjustment flexibility of the image collector 5 above the movable platform 404.

[0027] Reference Figure 4One side of the fixing seat 11 is fixedly connected to a support plate 12, and the shape of the support plate 12 is U-shaped. The inner wall of the support plate 12 is provided with a splint 13, and one side of the splint 13 is in contact with the surface of the image collector 5. The inner wall of the support plate 12 is rotatably connected to a bidirectional screw 14, and the surface of the bidirectional screw 14 is threadedly connected to the inner cavity of the splint 13. Through the provided splint 13, the support plate 12 can provide semi-enclosed protection for the installation of the image collector 5, and the bidirectional screw 14 can be driven to rotate by the handle at one end of the bidirectional screw 14. The splint 13 is provided with two groups. Since the two groups of splints 13 are respectively threadedly connected to one end of the bidirectional screw 14, the rotation of the bidirectional screw 14 can drive the two groups of splints 13 to approach or move away from each other, thereby using different models of image collectors 5 for installation.

[0028] Reference Figure 4 One side of the splint 13 is fixedly connected to the limiting rod 15, the surface of the limiting rod 15 is slidably connected to the inner cavity of the support plate 12, and one end of the limiting rod 15 is fixedly connected to the limiting plate 16.

Through the set cylinder 17, the cylinder 17 can drive the push rod 18 to push the fixed seat 11 and the image collector 5 for horizontal adjustment, thereby adjusting the distance of automobile fluid valves of different shapes.

[0030] Working principle: The column 1 cooperates with the supporting foot 3 to play the main supporting role. The automobile fluid valve to be tested can be placed above the placement table 2. The fixing seat 11 is mainly used for the installation of the image collector 5. The extension plate 10 facilitates the adjustment flexibility of the image collector 5 above the mobile platform 404. The support plate 12 can provide semi-enclosed protection for the installation of the image collector 5. The handle at one end of the bidirectional screw 14 can drive the bidirectional screw 14 to rotate. There are two groups of splints 13. Since the two groups of splints 13 are respectively threadedly connected to one end of the bidirectional screw 14, the rotation of the bidirectional screw 14 can drive the two groups of splints 13 to move closer to or away from each other, so that different types of image collectors 5 can be installed. The image acquisition mechanism 4 can drive the image collector 5 to perform circular motion along the surface of the column 1. The mounting ring 401 and the support ring 402 in the image acquisition mechanism 4 both play a supporting and connecting role. The drive motor 405 is activated to drive the gear 406 to rotate. Since the teeth of the gear 406 are engaged with the surface of the gear block 407, the gear 406 can drive the movable platform 404 to slide circularly along the track 403 when it rotates. The cylinder 17 can drive the push rod 18 to push the fixed seat 11 and the image collector 5 to perform lateral adjustment, thereby adjusting the distance of automobile fluid valves of different shapes. The image acquisition mechanism 4 drives the image collector 5 to automatically collect automobile fluid valves, thereby improving stability and ensuring efficiency.
