Description

Technical Field

[0001] This utility model relates to the field of dashboard inspection technology, specifically to an automatic dashboard inspection device based on machine vision. Background Technology

[0002] Dashboards require multiple inspections during production, necessitating the use of vision inspection devices. A dashboard vision inspection instrument is an automated device used to inspect the appearance and function of dashboards, primarily applied in the automotive, aerospace, and industrial equipment industries. It automatically identifies scales, pointers, indicator lights, and other features on the dashboard using high-resolution cameras and image processing technology, ensuring compliance with quality standards.

[0003] In existing technologies, dashboards are typically placed on a testing station of a testing platform, and high-resolution images of the dashboard are automatically captured by a camera for testing and result analysis. However, in actual use, because the camera lens is exposed to the air for a long time, a lot of dust will accumulate on the lens surface as the testing work continues. Therefore, the lens needs to be cleaned frequently. However, high-frequency cleaning can easily damage the lens, affect the lifespan of the camera, and thus increase costs. Therefore, it is necessary to improve the automatic dashboard testing device based on machine vision to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide an automatic dashboard inspection device based on machine vision to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic instrument panel inspection device based on machine vision, comprising an inspection instrument body, a placement platform fixedly installed on the top of the inspection instrument body, a support frame fixedly installed on the top of the inspection instrument body, a visual inspection camera disposed outside the support frame, a positioning mechanism disposed outside the visual inspection camera, and a blocking mechanism disposed outside the positioning mechanism.

[0006] Preferably, the positioning mechanism includes a surrounding shell, which is slidably mounted on the outside of the visual inspection camera. An optical lens is fixedly mounted inside the surrounding shell. A sealing ring is fixedly mounted on the top of the surrounding shell. A connecting plate is fixedly mounted on the outside of the surrounding shell. An extension frame is fixedly mounted on the front of the visual inspection camera. A threaded post is threaded inside the extension frame. A sliding plate is rotatably mounted on the back of the threaded post. The sliding plate is slidably mounted on the inner wall of the extension frame. A sliding rod is fixedly mounted on the back of the sliding rod. A triangular block is fixedly mounted on the end of the sliding rod away from the sliding plate. An clearance groove is formed inside the connecting plate. The triangular block is movably mounted inside the clearance groove. A semi-circular block is fixedly mounted inside the clearance groove. A positioning block is fixedly mounted on the outside of the visual inspection camera. This facilitates the protection of the lens of the visual inspection camera, reduces the frequency of direct cleaning of the visual inspection camera, and lowers the risk of damage.

[0007] Preferably, a through groove is provided inside the positioning block at a position corresponding to the connecting plate, and the connecting plate is slidably installed in the through groove to facilitate the positioning of the connecting plate.

[0008] Preferably, a through groove is provided inside the positioning block at the position corresponding to the slide rod, and the slide rod is slidably installed in the through groove to facilitate the movement of the slide rod.

[0009] Preferably, the shielding mechanism includes a surrounding block, which is slidably mounted on the outside of the surrounding shell. A cover plate is fixedly mounted on the bottom of the surrounding block, and a picking post is fixedly mounted on the bottom of the cover plate. A magnet is fixedly mounted inside the cover plate, and a metal plate is fixedly mounted inside the surrounding shell. This facilitates shielding the optical lens when no inspection is required, reducing the frequency of cleaning the optical lens.

[0010] Compared with the prior art, this utility model provides an automatic dashboard inspection device based on machine vision, which has the following beneficial effects:

[0011] 1. This machine vision-based automatic dashboard inspection device, through its positioning mechanism, protects the lens of the vision inspection camera during use via a surrounding shell and optical lenses. In daily use, only dust on the surface of the optical lenses needs to be cleaned, reducing the frequency of direct cleaning of the vision inspection camera, lowering the risk of damage, and increasing the camera's lifespan. The positioning block facilitates the positioning of the connecting plate, and the rotating threaded column allows the sliding rod to move. The cooperation of the triangular block and semi-circular block facilitates the upward movement of the connecting plate, ensuring a tight fit between the sealing ring and the vision inspection camera, preventing dust from entering the surrounding shell.

[0012] 2. This machine vision-based automatic dashboard inspection device, through its shielding mechanism, facilitates the positioning of the cover plate by the surrounding block during use, and the limiting operation of the cover plate by the magnet and metal plate. This allows for shielding of the optical lenses when inspection is not required, reducing the frequency of cleaning the optical lenses. By pulling the pick-up column, the cover plate can be quickly moved away from the surrounding shell, facilitating subsequent dashboard inspection. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0022] Example 1:

[0023] Please see Figure 1-3 This utility model provides a technical solution: an automatic instrument panel detection device based on machine vision, including a detector body 1, a placement platform 2 fixedly installed on the top of the detector body 1, a stand 3 fixedly installed on the top of the detector body 1, a visual inspection camera 4 arranged outside the stand 3, a positioning mechanism 5 arranged outside the visual inspection camera 4, and a blocking mechanism 6 arranged outside the positioning mechanism 5.

[0024] Furthermore, the positioning mechanism 5 includes a surrounding shell 501, which is slidably mounted on the outside of the visual inspection camera 4. An optical lens 502 is fixedly mounted inside the surrounding shell 501. A sealing ring 503 is fixedly mounted on the top of the surrounding shell 501. A connecting plate 504 is fixedly mounted on the outside of the surrounding shell 501. An extension frame 505 is fixedly mounted on the front of the visual inspection camera 4. A threaded post 506 is threaded inside the extension frame 505. A sliding plate 507 is rotatably mounted on the back of the threaded post 506. The sliding plate 507 is slidably mounted on the extension frame 4. On the inner wall of the frame 505, a slide bar 508 is fixedly installed on the back of the slide plate 507. A triangular block 509 is fixedly installed on the end of the slide bar 508 away from the slide plate 507. An avoidance groove 510 is opened inside the connecting plate 504. The triangular block 509 is movably installed inside the avoidance groove 510. A semi-circular block 511 is fixedly installed inside the avoidance groove 510. A positioning block 512 is fixedly installed on the outside of the visual inspection camera 4 to facilitate the protection of the lens of the visual inspection camera 4, reduce the frequency of direct cleaning of the visual inspection camera 4, and reduce the risk of damage.

[0025] Furthermore, a through groove is provided inside the positioning block 512 at the position corresponding to the connecting plate 504, and the connecting plate 504 is slidably installed in the through groove, which facilitates the positioning of the connecting plate 504.

[0026] Furthermore, a through groove is provided inside the positioning block 512 at the position corresponding to the slide rod 508, and the slide rod 508 is slidably installed in the through groove to facilitate the movement of the slide rod 508.

[0027] Example 2:

[0028] Please see Figure 4-5 Furthermore, in conjunction with Embodiment 1, the shielding mechanism 6 includes a surrounding block 601, which is slidably installed on the outside of the surrounding shell 501. A cover plate 602 is fixedly installed on the bottom of the surrounding block 601, and a picking post 603 is fixedly installed on the bottom of the cover plate 602. A magnet 604 is fixedly installed inside the cover plate 602, and a metal plate 605 is fixedly installed inside the surrounding shell 501. This facilitates shielding the optical lens 502 when no inspection is required, thereby reducing the frequency of cleaning the optical lens 502.

[0029] In actual operation, when this device is used, the enclosure 501 is slidably installed outside the vision inspection camera 4, causing the connecting plate 504 to slide inside the positioning block 512. By rotating the threaded column 506, the sliding plate 507 and the sliding rod 508 move towards the vision inspection camera 4, causing the triangular block 509 to contact the semi-circular block 511. As the sliding rod 508 continues to move, the connecting plate 504 moves upward, causing the sealing ring 503 to make tight contact with the vision inspection camera 4, thus completing the installation of the enclosure 501. When the instrument panel is being inspected, dust adheres to the outside of the optical lens 502. Only the optical lens 502 needs to be cleaned periodically to reduce the frequency of directly cleaning the visual inspection camera (4). When inspection is not required, the cover plate 602 is limited by sliding the surrounding block 601 outside the surrounding shell 501 and by using the magnet 604 and the metal plate 605 to block the optical lens 502. By pulling the pick-up column 603, the cover plate 602 can be quickly moved away from the surrounding shell 501, which facilitates the subsequent inspection of the instrument panel.
