Description

Technical Field

[0001] This utility model relates to the field of aluminum hot continuous rolling quality inspection technology, specifically a sample stage for determining the grade of anodizing. Background Technology

[0002] Anodizing is a crucial step in the production of aluminum and aluminum alloy sheets. Its quality grade directly affects the corrosion resistance, wear resistance, and appearance of the products, and is an important aspect of quality inspection for hot-rolled aluminum products. Currently, the industry primarily relies on manual methods to determine the anodizing grade, where operators visually compare the aluminum sample to be tested with a standard sample under natural or ordinary light.

[0003] This traditional manual assessment method has significant limitations. First, the human eye is highly subjective; judgments of the color, uniformity, and density of the oxide film are easily influenced by ambient light, observation angle, and the operator's experience and physiological state, leading to poor consistency and low repeatability of the results. Second, when the oxidation effect of a sample falls between two adjacent standard levels, manual assessment struggles to accurately distinguish and quantify the differences, easily resulting in misjudgments or disputes, thus affecting the accuracy and impartiality of quality control. Furthermore, manual comparison is inefficient and fails to meet the demands of modern industrial production for efficient and rapid testing.

[0004] To overcome these drawbacks, the industry has begun to explore using machine vision technology to replace human eyes and develop automated judgment instruments. These instruments typically place the sample on an observation platform, acquire images via a top-mounted camera, and then analyze and judge the data using software algorithms. However, existing observation platforms are mostly open structures, with the sample directly exposed to the environment. This structure has the following drawbacks: stray light from the environment can interfere with the color and brightness of the images captured by the camera, affecting the accuracy of the analysis; simultaneously, dust easily accumulates on the platform and internal optical components, increasing maintenance costs and potentially contaminating the sample or blocking light, leading to distorted detection signals.

[0005] Therefore, this application provides a dedicated sample stage that can provide a stable, clean, and standardized observation environment for machine vision inspection, so as to ensure the accuracy and reliability of the automatic determination results of anodizing grade.

[0016] 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.

[0017] Please see Figure 1-2 This utility model provides a technical solution: a sample stage for determining anodizing grade, including a base 1, a groove on the upper surface of the base 1, and evenly distributed support rollers 2 inside the groove. A box 5 is provided in the middle of the upper surface of the base 1, and a through hole is provided between the box 5 and the base 1. Evenly distributed LED beads 51 are provided on the inner side of the box 5, which can provide stable lighting conditions. A sliding groove is provided in the middle of the upper surface of the box 5, and a camera 72 is slidably arranged inside the sliding groove. The position of the camera 72 can be adjusted so that when the sample is small and can only be inserted into one end of the box 5, the camera 72 can be moved to the side of the box 5 closer to the sample.

[0018] Furthermore, the base 1 is provided with an elastic column 3 on the side corresponding to one side of the box 5. The top of the elastic column 3 is provided with a mounting seat 31. A conveying roller 4 is rotatably mounted on the mounting seat 31. A servo motor 41 that drives the conveying roller 4 to rotate is provided on the side of one of the mounting seats 31. The output shaft of the servo motor 41 is connected to one end of the conveying roller 4 through a coupling. The servo motor 41 drives the conveying roller 4 to rotate, and the conveying roller 4 conveys the sample.

[0019] Furthermore, a vertical electric push rod 6 is provided on the side of the housing 5 corresponding to the through hole. The telescopic end of the vertical electric push rod 6 is provided with a sealing plate 61 to block the through hole. The vertical electric push rod 6 drives the sealing plate 61 to block the housing 5 during non-working periods, reducing the entry of dust.

[0020] Furthermore, a slider 7 is slidably provided inside the groove, and the camera 72 is mounted on the slider 7, which facilitates the adjustment of the position of the camera 72.

[0021] Furthermore, the upper side of the box 5 corresponding to the slider 7 is provided with a horizontal electric push rod 71 that is parallel to the slide groove, and the telescopic end of the horizontal electric push rod 71 is connected to the slider 7.

[0022] Furthermore, the top of the housing 5 is provided with a transparent cover 8 that covers the slide groove to prevent dust from falling into the interior of the housing 5 from the slide groove.

[0023] The servo motor 41, LED bead 51, vertical electric push rod 6, horizontal electric push rod 71, and camera 72 used in this utility model are all commonly used electronic components in the prior art. Their working methods and circuit structures are well-known technologies and will not be described in detail here. The servo motor 41, LED bead 51, vertical electric push rod 6, horizontal electric push rod 71, and camera 72 are all electrically connected to an external switch group.

[0024] When using: Step 1: Place the sample on the support roller 2 on the base 1, and insert one end of the defective sample between the support roller 2 and the conveyor roller 4; Step 2: Control the vertical electric push rod 6 to shorten, and the vertical electric push rod 6 will drive the sealing plate 61 to move upward; Step 3: Control the servo motor 41 and camera 72 to work. The servo motor 41 drives the conveyor roller 4 to rotate, and the conveyor roller 4 conveys the sample, so that the sample enters the box 5. Then the camera 72 collects the image information of the sample. When the sample is insufficient to pass through the two through holes of the housing 5, in order to prevent the sample from being unable to be removed from the housing 5, the surface image of the sample can be acquired in two separate steps, as follows: Step 4: First, repeat steps 1 to 3 to acquire half of the image information of the sample, and then control the servo motor 41 to flip so that the sample is removed. Step 5: Rotate the sample image vertically by 180 degrees and repeat step 4 to complete the acquisition of the entire image information of the sample image.

[0025] This invention, by setting up a closed box structure and incorporating controllable LED beads 51 as a light source, effectively isolates the interference of stray light from the external environment, providing a stable lighting environment for the camera 72 to acquire images, thereby improving the accuracy and reliability of automatic determination of anodizing level; and can seal the box 5 when not in operation to prevent dust from entering and contaminating the optical components inside the box 5, ensuring the cleanliness of the optical system and the authenticity of the test results, while reducing the maintenance frequency and cost of the equipment.
