The use of terms like "first" and "second" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the quantity or sequence of the indicated technical features.

[0024] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0025] Please see Figure 1-4This utility model provides a technical solution: an automatic multi-angle glass defect identification mechanism, including a device base plate 1 and a multi-angle identification mechanism. The multi-angle identification mechanism includes a lifting bracket 9, a movable frame 12, a telescopic rod 13, a sliding component 14, an arc-shaped support plate 15, an arc-shaped groove 16, and a visual identification mechanism 17. The lifting bracket 9 is set on the top of the device base plate 1. The movable frame 12 is slidably connected to the bottom of the lifting bracket 9. The telescopic rod 13 is slidably connected to the inside of the movable frame 12. The sliding component 14 is rotatably connected to the bottom of the telescopic rod 13. The arc-shaped support plate 15 is set on the bottom of the lifting bracket 9. The sliding component 14 is slidably connected to the outer surface of the arc-shaped support plate 15. The arc-shaped groove 16 is opened on the surface of the arc-shaped support plate 15. The sliding component 14 is slidably connected to the inside of the arc-shaped groove 16. The visual identification mechanism 17 is fixedly connected to the bottom of the sliding component 14.

[0026] Furthermore, electric slides 6 are fixedly connected to both sides of the top of the device base plate 1. A movable support 7 is fixedly connected to the top of the electric slides 6. An arc-shaped support plate 15 is fixedly connected to the surface of the movable support 7. Multiple second hydraulic cylinders 8 are fixedly connected to the top of the movable support 7. The output end of each second hydraulic cylinder 8 is fixedly connected to the lifting support 9. A drive motor 10 is fixedly connected to the surface of the lifting support 9. A threaded rod 11 is fixedly connected to the output end of the drive motor 10. The threaded rod 11 is rotatably connected to the surface of the lifting support 9. A movable frame 12 is threadedly sleeved on the outer surface of the threaded rod 11. A fixed plate 2 is fixedly connected to the top of the device base plate 1. A first hydraulic cylinder 3 is fixedly connected to the surface of the fixed plate 2. A positioning plate 4 is fixedly connected to the output of the first hydraulic cylinder 3. A curved glass 5 is provided on the top of the device base plate 1. The curved glass 5 is located directly below the arc-shaped support plate 15. Both sides of the curved glass 5 are in contact with the positioning plate 4.

[0027] Furthermore, the overall structure is supported by the base plate 1 of the device. After the positioning plate 4 centers and limits the curved glass 5 by the first hydraulic cylinder 3, the electric slide table 6 drives the moving bracket 7 to move the arc-shaped support plate 15 laterally. This causes the visual recognition mechanism 17, which is set at the bottom of the sliding component 14, to move laterally to identify and detect the glass surface. The second hydraulic cylinder 8 controls the height of the lifting bracket 9 and the visual recognition mechanism 17. The drive motor 10 drives the threaded rod 11 to move the moving frame 12 longitudinally, thereby moving the telescopic plate 13. Under the telescopic compensation of the telescopic rod 13, the visual recognition mechanism 17 closely follows the surface contour of the curved glass 5, forming a multi-degree-of-freedom motion trajectory in three-dimensional space. The sliding component 14 slides on the surface of the arc-shaped support plate 15 to achieve multi-angle optical acquisition that adapts to the curvature of the curved surface, identifying surface defects such as chipped edges, scratches, and white spots. During the detection process, the visual recognition mechanism 17 transmits the acquired data to the image processor in real time. Combined with the preset algorithm, the defect classification is completed and the sorting mechanism is triggered to remove unqualified products, realizing a fully automatic high-precision defect detection process for curved glass.

[0028] Furthermore, the system achieves omnidirectional inspection of curved glass through three-dimensional motion adjustment, enhances defect identification capabilities by employing arc trajectory scanning and multi-angle optical acquisition technology, ensures inspection accuracy through the coordinated operation of the mechanical structure and vision system, improves production efficiency through automated positioning and sorting functions, facilitates maintenance and adapts to the inspection needs of different glass specifications through modular design, and features a compact overall structure and stable operation. This system solves the problem of angular deviation between the optical axis of the inspection instrument and the normal direction of the curved glass, which leads to decreased defect identification accuracy in areas of curvature variation and is prone to blind spots and misjudgments.
