[0039] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0042] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0043] Please see Figures 1 to 7 As shown, this application provides a lens dust removal device, including a diverter seat 10 and a contour head 20 disposed on the diverter seat 10. The contour head 20 has an arc-shaped surface 21 adapted to the shape of the lens. The arc-shaped surface 21 has a concave arc structure adapted to the shape of the lens.

[0044] The curved surface 21 can closely fit various shapes of the lens surface. Whether it is a flat, spherical or aspherical lens, it can achieve comprehensive and precise dust removal on the upper and lower surfaces and edges. The air intake channel 40 maintains a uniform and appropriate distance from the lens surface. Optionally, the lens can be fitted with the curved surface 21 at a minimum distance of 1.5mm, which is a non-contact cleaning method that will not damage the product.

[0045] The air blowing channel 30 and the air suction channel 40 are arranged on the shunt seat 10 and the profiling head 20, and are arranged separately and penetrate the arc surface 21.

[0046] The air blowing channel 30 is a variable cross-section air flow channel capable of generating ultrasonic waves. When high-speed airflow flows through the variable cross-section air flow channel, strong oscillation is formed due to the interaction of the cavity mouth shear flow and the cavity flow, in this case, the interaction of the sound field and the flow field is enhanced, resulting in strong sound wave generation (i.e. ultrasonic waves). The ultrasonic waves and high-speed airflow blowing on the lens surface work together to remove dust particles on the lens surface.

[0047] Compared with manual wiping of the lens, the device does not leave scratches on the lens surface, and improves the dust removal efficiency; compared with the traditional air blowing device for dust removal, the device can remove small dust particles and improve the dust removal effect; compared with the wet ultrasonic dust removal, the device does not need additional cooling and drying device, which reduces the cost.

[0048] The dust removal device has a blowing and suction structure, forms a closed loop system, uses internally circulating clean air as a medium, does not damage the air balance of the clean room, does not cause secondary pollution, and can ensure that the dust blown can be cleaned in time, greatly improving the cleaning and dust removal efficiency.

[0049] The air blowing channel 30 includes an air inlet flow channel 31, a transition flow channel 32, an intermediate flow channel 33 and an air outlet flow channel 34 connected in sequence from bottom to top, the air inlet flow channel 31, the transition flow channel 32 and the intermediate flow channel 33 are located on the shunt seat 10, and the air outlet flow channel 34 is located on the profiling head 20; the cross-sectional area of the transition flow channel 32 is smaller than that of the air inlet flow channel 31 and the intermediate flow channel 33; the cross-sectional area of the air outlet flow channel 34 is smaller than that of the intermediate flow channel 33, that is, the cross-sectional areas of adjacent two flow channels are different. When the airflow flows through flow channels with different cross-sectional areas, the airflow is compressed and expanded multiple times, so that the air blowing channel 30 generates flow-induced oscillation, thereby generating ultrasonic waves.

[0050] The cross-sectional area of the transition flow channel 32 is greater than that of the air outlet flow channel 34, the cross-sectional area of the air inlet flow channel 31 is greater than that of the transition flow channel 32, and the cross-sectional area of the intermediate flow channel 33 is greater than that of the air inlet flow channel 31. The air outlet flow channel 34 is designed to be the smallest, so that the airflow can be blown out from the air outlet flow channel 204 at high speed, thereby easily blowing the dust on the lens surface.

[0051] Of course, in another embodiment, the cross-sectional area of the inlet flow channel 31 and the intermediate flow channel 33 can be the same, and the cross-sectional area of the transition flow channel 32 and the outlet flow channel 34 can also be the same.

[0052] In one embodiment, the transition flow channel 32, the intermediate flow channel 33 and the outlet flow channel 34 are all two, one of the transition flow channel 32 and the corresponding intermediate flow channel 33, outlet flow channel 34 form a first branch 301, the other transition flow channel 32 and the corresponding intermediate flow channel 33, outlet flow channel 34 form a second branch 302, the first branch 301 and the second branch 302 are both communicated with the inlet flow channel 31 at one end, and both penetrate the arc surface 21 at the other end.

[0053] The design of the two airflow branches makes the area covered by the airflow larger, and part of the air inlet channel 40 is located between the two airflow branches, so that the dust in the middle position can also be quickly sucked away.

[0054] The cross-sectional area of the inlet flow channel 31 is circular, which facilitates the installation of the air pipe joint; the cross-sectional area of the two intermediate flow channels 33 is semicircular, and the two transition flow channels 32 are located at the corners of the corresponding intermediate flow channels 33; the outlet flow channel 34 is a narrow strip hole structure. The ultrasonic wave effect generated by the air blowing channel of this structure will be better. Of course, the shape of each flow channel can also be other shapes, as long as it can generate ultrasonic waves.

[0055] Each of the outlet flow channels 34 includes a first air channel 341 communicated with the intermediate flow channel 33 and a second air channel 342 communicated with the first air channel 341, and the cross-sectional area of the second air channel 342 is smaller than that of the first air channel 341. The second air channel 342 is a very long strip hole structure, and the airflow blown out here is compressed and has a very fast flow rate, that is, the dust removal effect will be better.

[0056] The air inlet channel 40 includes a first air inlet part 41 and a second air inlet part 42, the first air inlet part 41 separates the first branch 301 and the second branch 302, and the second air inlet part 42 is located outside the first branch 301 and the second branch 302 and surrounds the first branch 301 and the second branch 302. The air inlet structure of this structure can perform air suction in all directions.

[0057] The air blowing channel 30 is connected with an air pipe joint 50 at the end away from the arc surface 21, and the air pipe joint 50 is connected with a compressed air source to provide positive pressure. The air inlet channel 40 is connected with an air suction flange 60 at the end away from the arc surface 21, and the air suction flange 60 is connected with a negative pressure source to recycle the dust blown up, thereby achieving the purpose of dust removal

[0058] The application also provides a lens dust removal device comprising the lens dust removal device. The device has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, and thus will not be described here again.

[0059] The above only describes the preferred embodiments of the application and is not intended to limit the application. Any modification, equivalent replacement and improvement made within the spirit and principle of the application shall be included in the protection scope of the application.
