Summary of the Invention

[0004] The purpose of this application is to provide a sealed protective device for a vision system, in order to solve the problem that the vision system inside the protective device has difficulty recognizing external information due to insufficient light brightness.

[0005] The visual system sealing and protection device provided in this application adopts the following technical solution:

[0006] A vision system sealing and protection device includes:

[0007] Protective housing for mounting camera equipment;

[0008] The light source assembly includes a light source protective cylinder and an annular light source. The light source protective cylinder is connected to a protective box, and the interior of the light source protective cylinder and the protective box are connected. The light source protective cylinder has a vision port, and the vision port is equipped with a glass plate. The glass plate closes the vision port. The annular light source is located on the inner wall of the light source protective cylinder and is used to provide illumination for the vision system.

[0009] By adopting the above technical solution, the connected protective box and light source protective cylinder can provide a sealed protective environment for the internal camera device. At the same time, the camera device can acquire information through the vision port and glass plate while preventing external debris from entering the protective device. Meanwhile, the ring light source in the light source assembly provides uniform illumination for the vision system, enabling the vision system to accurately observe external information and ensuring the working performance and image quality of the vision system in various environments.

[0010] Optionally, the protective box has a square structure, the light source protective tube has a cylindrical structure, and the area of ​​the connecting surface of the light source protective tube is larger than the area of ​​the connecting surface of the protective box.

[0011] By adopting the above technical solution, the square structure is suitable for the installation of the camera device, while the cylindrical light source protective tube can make the ring light source on the inner wall evenly illuminate, and the larger light source protective tube can make the ring light source surround the camera device, thus improving the image quality.

[0012] Optionally, it also includes a support frame with a movable groove, and a movable component connected to the protective box, which can move within the movable groove.

[0013] By adopting the above technical solution, the movable slot on the support frame, together with the movable component connected to the protective box, allows the protective box to move flexibly within the movable slot, thereby enabling convenient adjustment of the camera device position and improving the adaptability and flexibility of the vision system in different application scenarios.

[0014] Optionally, the light source assembly also includes a strip light source, which is connected to the outside of the light source protective casing.

[0015] By adopting the above technical solution, the strip light source is connected to the outside of the light source protective tube, which can provide additional lighting effects and enhance the applicable scenarios and flexibility of the vision system.

[0016] Optionally, the support frame is provided with mounting holes for connecting and mounting external devices.

[0017] By adopting the above technical solution, the mounting holes can be used to easily connect and install the support frame to external devices, and the support frame can also be easily moved on external devices through the mounting holes, thereby enabling the support frame to be easily installed and operated, improving the adaptability and ease of use of the device.

[0018] Optionally, the protective box is provided with a connection hole for connecting the inside and outside of the protective box.

[0019] By adopting the above technical solution, the protective box is equipped with a connection hole, which enables communication between the inside and outside of the protective box, facilitating the connection of lines or pipes, while ensuring the sealing of the protective box.

[0020] Optionally, a light-shielding pad is provided on the inside of the glass plate to prevent the glass plate from reflecting light onto the camera device.

[0021] By adopting the above technical solution, since the glass plate reflects some of the light emitted by the ring light source onto the camera device, resulting in a decrease in image quality, a light-shielding pad is set on the inside of the glass plate to effectively prevent the glass plate from reflecting light onto the camera device, thereby improving image quality.

[0022] Optionally, a sealing gasket is provided between the glass plate and the light source protective casing.

[0023] By adopting the above technical solutions, the sealing performance of the vision system sealing and protection device can be effectively improved, preventing external dust and moisture from entering the light source protection cylinder, ensuring a clean working environment for the camera device, and thus improving the stability and reliability of the vision system.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. The connected protective box and light source protective tube can provide a sealed protective environment for the internal camera device, and through the vision port and glass plate, the camera device can acquire information while preventing external debris from entering the protective device. At the same time, the ring light source in the light source assembly provides a uniform illumination effect for the vision system, so that the vision system can accurately observe external information and ensure the working performance and image quality of the vision system in various environments.

[0026] 2. A square structure is suitable for the installation of camera devices, while a cylindrical light source shield can make the ring light source on the inner wall evenly illuminate the device, and a larger light source shield can make the ring light source surround the camera device, thus improving image quality.

[0027] 3. Since the glass plate reflects some of the light emitted by the ring light source back to the camera device, resulting in a decrease in image quality, a light-shielding pad is placed on the inside of the glass plate to effectively prevent the glass plate from reflecting light back to the camera device, thereby improving image quality.

[0032] The present application will be further described in detail below with reference to the accompanying drawings.

[0033] A sealing and protective device for a vision system, referring to Figure 1 and Figure 2 The system includes a protective box 1, a light source assembly 2, and a support frame 3. The protective box 1 houses the camera device. The light source assembly 2 includes a protective tube 21 and a ring-shaped light source 22. The protective tube 21 is connected to the protective box 1, and the interiors of the tube and box are interconnected, allowing the camera device to penetrate the tube. The protective tube 21 has a viewing port 23 through which the camera device illuminates the outside and acquires external information. A glass plate 24 is provided to close the viewing port 23, preventing external debris from entering the protective device. The ring-shaped light source 22 is located on the inner wall of the protective tube 21, providing uniform illumination for the vision system, enabling the camera device to acquire reflected light more clearly and effectively, thus improving image acquisition quality. The support frame 3 has a moving groove 31. A moving component 11 is connected to the side of the protective box 1 adjacent to the protective tube 21. The moving component 11 can move within the moving groove 31, thereby causing the protective box 1 and the light source assembly 2 to move up and down.

[0034] In this embodiment, the protective box 1 has a square structure, and the light source protective tube 21 has a cylindrical structure. The area of ​​the connecting surface of the light source protective tube 21 is larger than the area of ​​the connecting surface of the protective box 1. The square structure is suitable for the installation of the camera device, while the cylindrical light source protective tube 21 can make the ring light source on the inner wall evenly illuminated. The larger light source protective tube 21 can make the ring light source surround the camera device, improving the imaging quality.

[0035] Reference Figure 1 The protective box 1 has a connection hole 12 inside, which is used to connect the inside and outside of the protective box 1. This ensures that external devices can be connected to the camera device while maintaining the protective performance of the protective box 1.

[0036] Reference Figure 2 The support frame 3 is also provided with a through mounting hole 32. The mounting hole 32 can be used to easily connect and install the support frame 3 to an external device. The support frame 3 can also be moved on the external device through the mounting hole 32, so that the support frame 3 can be easily installed and operated, improving the adaptability and ease of use of the device.

[0037] Reference Figure 3 A sealing gasket 27 is provided between the light source protective casing 21 and the glass plate 24. The sealing gasket 27 is made of a high-temperature resistant and weather-resistant material, such as polypropylene or polyethylene, which improves the sealing performance of the light source protective casing 21 and prevents external contaminants from entering. A light-shielding plate is also provided on the inner side of the glass plate 24. Since the glass plate 24 reflects some of the light emitted by the ring light source 22 back to the camera device, resulting in a decrease in image quality, the light-shielding gasket 26 on the inner side of the glass plate 24 can effectively prevent the glass plate 24 from reflecting light back to the camera device, thereby improving image quality.

[0038] The implementation principle of this embodiment is as follows: By installing the camera device inside the protective box 1 and setting a light source protective cylinder 21 and a ring light source 22 outside the protective box 1, both sealing performance and sufficient illumination for the camera device are ensured. Simultaneously, by setting a light-shielding pad 26 on the glass plate 24, reflection interference is avoided, improving image acquisition quality. By setting a support frame 3 and a movable component 11, the protective box 1 and the light source assembly 2 can be moved vertically, allowing the height of the camera device to be adjusted according to actual needs. In summary, this embodiment not only has good sealing performance, sufficient illumination, and avoidance of reflection interference, but also adds the height adjustment function of the camera device, significantly improving the flexibility and adaptability of the vision system.

[0039] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
