By adjusting the light source, the contrast and clarity of the image can be significantly improved, making the features in the image more obvious, which is convenient for subsequent image processing and analysis. The brightness can be adjusted according to actual needs to avoid unnecessary energy waste and achieve energy saving and high efficiency. The range of blocking is adjusted by the overlapping of the movable light shield and the fixed light shield, thereby blocking the light source group above, thereby reducing the range of light source propagation. Adjusting the light source enables the vision system to adapt to different lighting conditions and environments. Clear images can be obtained in both strong light and dark environments. A suitable light source can reduce glare and reflection, thereby improving the accuracy of visual detection and reducing false detection and missed detection.

[0022] 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.

[0023] Please see Figure 1-6 The present invention provides a technical solution as follows:

[0024] Example 1:

[0025] An intelligent vision device with light source adjustment function includes a frame 1. An adjustment component 2 is installed inside the frame 1. An electric telescopic rod 3 is fixedly connected to the output end of the adjustment component 2. A connecting rod 4 is fixedly connected to the output of the electric telescopic rod 3. A protective cover 5 is fixedly connected to one end of the connecting rod 4. A light source lamp group 6 is fixedly connected to the inner wall of the protective cover 5. A vision camera 7 is installed on the inner wall of the light source lamp group 6. A light source blocking component 8 is installed on the inner wall of the protective cover 5. A fixed light-shielding plate 9 is fixedly connected to the outer wall of the light source lamp group 6. A transparent air tube 10 is installed inside the light source blocking component 8. A jet pipe 11 is fixedly connected to one end of the transparent air tube 10. A light-concentrating cover 12 is fixedly connected to the inner wall of the protective cover 5.

[0026] The above structure can block the projected light source through the light source blocking component 8. By adjusting the light source, the contrast and clarity of the image can be significantly improved, making the features in the image more obvious, which is convenient for subsequent image processing and analysis. The brightness can be adjusted according to actual needs to avoid unnecessary energy waste.

[0027] Furthermore, the adjustment assembly 2 includes a drive motor 201, a threaded rod 202, a threaded sleeve 203, and a slider 204. The drive motor 201 is installed inside the frame 1. The output shaft of the drive motor 201 is fixedly connected to the threaded rod 202 via a coupling. The threaded sleeve 203 is installed on the external thread of the threaded rod 202. The slider 204 is fixedly connected to the outer wall of the threaded sleeve 203.

[0028] The above structure drives the threaded rod 202 to rotate via the drive motor 201, thereby causing the threaded sleeve 203 and the slider 204 to be adjusted up and down along the frame 1.

[0029] Furthermore, the interior of the light source shielding assembly 8 includes a steering motor 801, a linkage rod 802, a mounting shaft 803, a movable cover 804, and a movable light shield 805. The steering motor 801 is installed on the inner wall of the protective cover 5. The output shaft of the steering motor 801 is fixedly connected to the linkage rod 802 through a coupling. One end of the linkage rod 802 is fixedly connected to the mounting shaft 803. One end of the linkage rod 802 is connected to the movable cover 804 through the mounting shaft 803. The movable light shield 805 is fixedly connected to the central shaft of the mounting shaft 803.

[0030] The above structure utilizes the overlapping of the movable light-shielding plate 805 and the fixed light-shielding plate 9 to adjust the range of shading, thereby blocking the light source group 6 above and reducing the propagation range of the light source.

[0031] Furthermore, the outer wall of the protective cover 5 is provided with a vent, and the interior of the protective cover 5 is a hollow structure. A through hole is opened on one side of the movable cover 804, and a transparent air tube 10 is installed at the through hole position. The movable cover 804 is located between the condenser cover 12 and the light source group 6, and the movable cover 804 slides along the edge of the condenser cover 12 and the light source group 6. The inner wall of the movable light shield 805 is provided with a slot. The fixed light shield 9 and the movable light shield 805 can overlap each other, and the size of the movable light shield 805 is larger than the size of the fixed light shield 9.

[0032] The above structure, through the hollow design inside the protective cover 5, facilitates the introduction of gas, enabling subsequent cleaning.

[0033] Furthermore, the jet pipe 11 is an arc-shaped air pipe, and the jet pipe 11 is located at the lens position of the visual camera 7.

[0034] The above structure reduces dust adhesion by cleaning the position of the vision camera 7 through the jet pipe 11.

[0035] Working principle: In use, firstly, the drive motor 201 drives the threaded rod 202 to rotate, thereby driving the threaded sleeve 203 and the slider 204 to adjust up and down along the frame 1, thereby driving the electric telescopic rod 3 to adjust its position up and down. At the same time, the electric telescopic rod 3 can be extended and retracted. It is connected to the protective cover 5 by the connecting rod 4, thereby adjusting the position of the intelligent vision device.

[0036] Secondly, the light source blocking component 8 can block the projected light source. By adjusting the light source, the contrast and clarity of the image can be significantly improved, making the features in the image more obvious. The brightness can be adjusted according to actual needs to avoid unnecessary energy waste and achieve energy efficiency. The movable light shield 805 and the fixed light shield 9 overlap, that is, the steering motor 801 is started, driving the linkage rod 802 to rotate, thereby driving the mounting shaft 803 and the movable cover 804 to rotate. The bottom movable light shield 805 rotates around the light source lamp group 6 with the mounting shaft 803. The range of blocking is adjusted by the overlapping range of the fixed light shield 9 and the movable light shield 805, thereby blocking the light source lamp group 6 above, thereby reducing the light source propagation range. Adjusting the light source allows the visual system to adapt to different lighting conditions and environments.

[0037] Finally, gas is injected into the protective cover 5 and sprayed out through the jet pipe 11. This air jet cleaning of the vision camera 7 removes dust, dirt, or fingerprints from the camera lens, improving the clarity and quality of captured images and ensuring that the vision system can accurately identify and analyze images. For applications that rely on the vision camera 7 for object recognition, detection, or measurement, a clean camera can provide more accurate image data, reducing misjudgments and errors. At the same time, gas cleaning is more environmentally friendly, reducing damage to the lens from chemical agents and water washing methods, thus extending the lifespan of the device.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
