Description

Technical Field

[0001] This utility model relates to the field of plate defect detection technology, and in particular to a defect detection device for magnesium alloy plates. Background Technology

[0002] Magnesium alloy sheets are sheets made of magnesium as the base and other elements added. Magnesium alloys have low density, high strength, good shock absorption and heat dissipation, as well as good electromagnetic shielding performance and environmental friendliness. They are usually made into different shapes according to process requirements.

[0003] A search of Chinese patent publication number "CN218272036U" reveals "a board defect detection device". This device automatically transports boards through a conveyor, saving manpower. The CCD detection camera can display various parts of the board in high definition, making it easy for workers to observe the location of the problem and reducing the burden on the human eye. The marking displacement module can automatically mark the problematic areas of the board. Based on the above search and existing technology, it was found that the aforementioned patent has certain defects. Although the device has the function of photographing and detecting defective plates, in practical applications, given that some magnesium alloy plates are curved due to process requirements, the CCD inspection camera is prone to problems during the shooting process. Specifically, when dealing with magnesium alloy sheets of varying thicknesses and curvatures, the equipment struggles to maintain a relatively constant shooting distance between the industrial camera and the sheet surface, which can easily lead to severe image distortion and affect the accuracy of defect detection. Utility Model Content

[0004] (a) Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides a defect detection device for magnesium alloy plates, which solves the technical problem of inaccurate detection by existing equipment.

[0005] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: A defect detection device for magnesium alloy plates includes a roller conveyor; The roller conveyor is symmetrically and fixedly installed with an adaptive curvature detection mechanism at its upper end; The adaptive curvature detection mechanism includes side columns, each side column having a first groove inside, each first groove having a first slider slidably mounted inside, each first slider having a lightweight connecting rod fixedly mounted on its side wall, and an industrial camera fixedly mounted between the lightweight connecting rods. The roller conveyor has multiple electric conveying rollers inside, each electric conveying roller having an inner transmission shaft inside, one of which has a rotating ring symmetrically mounted on its circumferential surface. The industrial camera is tilted.

[0006] Preferably, each of the rotating rings has a fixed rod fixedly installed at its upper end, and each fixed rod has an L-shaped rod symmetrically fixedly installed on its side wall. The L-shaped rod is fixedly installed with the side column, and each fixed rod has a second sliding groove inside.

[0007] Preferably, a second slider is fixedly installed inside each of the second slide grooves, and a guide rod is fixedly installed at the upper end of each of the second sliders.

[0008] Preferably, each of the conductive rods extends partially above the fixed rod, and each of the conductive rods is fixedly installed with a lightweight connecting rod.

[0009] Preferably, a guide roller is rotatably mounted between the second sliders, and the guide roller is located above the electric conveyor roller.

[0010] (III) Beneficial Effects Firstly, by setting up an adaptive curvature detection mechanism, after the guide roller makes adaptive contact with the curvature of the board surface, the sliding of the second slider in the second groove drives the guide rod to move vertically, and the linkage of the lightweight connecting rod adjusts the height of the industrial camera, ensuring that the board surface with different thicknesses and curvatures maintains a relatively constant shooting distance with the industrial camera, thus eliminating some image distortion problems caused by poor shooting distance. Secondly, by setting the first slide and the second slide, when the adaptive curved detection mechanism moves, the second slider will slide inside the second slide, while the lightweight connecting rod will drive the first slider to slide inside the first slide, thereby providing multiple limits and increasing stability.

[0014] This application provides a magnesium alloy sheet defect detection device, effectively solving the technical problem of inaccurate detection in existing equipment. By setting an adaptive curved detection mechanism, when the guide roller makes adaptive contact with the curvature of the sheet surface, the sliding of the second slider in the second groove drives the guide rod to move vertically, and the linkage of the lightweight connecting rod adjusts the height of the industrial camera, ensuring that the sheet surfaces of different thicknesses and curvatures maintain a relatively constant shooting distance from the industrial camera, eliminating some image distortion problems caused by poor shooting distance. By setting a first groove and a second groove, when the adaptive curved detection mechanism moves, the second slider will slide inside the second groove, and at the same time, the lightweight connecting rod will drive the first slider to slide inside the first groove, thereby providing multiple limits and increasing stability. Example

[0015] like Figures 1-4 As shown, the technical solution in this application embodiment effectively solves the technical problem of inaccurate detection by existing equipment. The overall idea is as follows: To address the problems existing in the prior art, this utility model provides a defect detection device for magnesium alloy plates, including a roller conveyor 11; The roller conveyor 11 is symmetrically and fixedly equipped with an adaptive curvature detection mechanism at its upper end; The adaptive curved detection mechanism includes side columns 12, each side column 12 has a first groove 13 inside, each first groove 13 has a first slider 14 slidably installed inside, each first slider 14 has a lightweight connecting rod 15 fixedly installed on its side wall, and an industrial camera 16 is fixedly installed between the lightweight connecting rods 15. The roller conveyor 11 has multiple electric conveying rollers 17 inside, each electric conveying roller 17 has an inner transmission shaft 18 inside, one of the inner transmission shafts 18 has a rotating ring 19 symmetrically mounted on its circumferential surface, the industrial camera 16 is tilted, each rotating ring 19 has a fixed rod 21 fixedly installed at its upper end, each fixed rod 21 has an L-shaped rod 22 symmetrically fixedly installed on its side wall, the L-shaped rod 22 is fixedly installed with the side column 12, and each fixed rod 21 has a second groove 23 inside. By setting an adaptive curvature detection mechanism, when the guide roller 26 makes adaptive contact with the curvature of the board surface, the guide rod 25 moves vertically through the sliding of the second slider 24 in the second slide groove 23, and the lightweight connecting rod 15 is linked to adjust the height of the industrial camera 16, so as to ensure that the board surface with different thicknesses and curvatures maintains a relatively constant shooting distance with the industrial camera 16, thus eliminating a certain image distortion problem caused by poor shooting distance. The lifting mechanism formed by the first slide 13 and the first slider 14, combined with a lightweight connecting rod design, enables the industrial camera 16 to quickly respond to surface changes, match the dynamic conveying status of the magnesium alloy plate in real time, and improve the imaging clarity of defects in high curvature areas.

[0016] Each second slide 23 has a second slider 24 fixedly installed inside, and a guide rod 25 is fixedly installed at the upper end of each second slider 24. Each guide rod 25 extends partially above the fixed rod 21. Each guide rod 25 is fixedly installed with the lightweight connecting rod 15. A guide roller 26 is rotatably installed between the second sliders 24. The guide roller 26 is located above the electric conveying roller 17. By setting the first slide groove 13 and the second slide groove 23, when the adaptive curved detection mechanism moves, the second slider 24 will slide inside the second slide groove 23. At the same time, the lightweight connecting rod 15 will drive the first slider 14 to slide inside the first slide groove 13, thereby providing multiple limits and increasing stability.

[0017] Working principle: In use, the operator first places the curved plate on the roller conveyor 11 and conveys it by the electric conveyor roller 17. Due to the thickness of the plate itself and the curvature of its curve, when the surface of the plate contacts the guide roller 26, the guide roller 26 will drive the second slider 24 and the guide rod 25 to slide upward in the second groove 23 along the curvature of the plate surface. This causes the guide rod 25 to push the lightweight connecting rod 15 to move upward, which in turn drives the first slider 14 and the industrial camera 16 to move. This ensures that the industrial camera 16 can always maintain an optimal shooting distance from the plate, thereby completing efficient photographic defect detection.

[0018] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
