Description

Technical Field

[0001] This utility model relates to the field of optical instrument manufacturing and precision testing technology, and in particular to a dust removal device for lenses. Background Technology

[0002] In the lens production and processing process, the surface cleanliness directly determines the system imaging quality and optical path accuracy. With the development of optoelectronic technology, irregularly shaped lenses (such as aspherical lenses, prisms, Fresnel lenses and miniature curved lenses) are widely used in high-end cameras, laser equipment and aerospace detection instruments due to their optical performance advantages. Dust removal is a key link to ensure optical performance.

[0003] Regarding the above and existing related technologies, the inventors believe that the following defects often exist: the fixing mechanism of existing lens dust removal devices is mostly designed for traditional circular plane lenses. The rigid adjustable clamps achieve fixing through mechanical limiting, but cannot adapt to the curvature changes of irregular curved surfaces. The lens edge is prone to cracking or surface scratches due to contact stress concentration, which in turn affects the optical performance and service life of the lens. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the existing lens dust removal devices have the disadvantages of poor adaptability and easy damage to the lens. Therefore, we propose a lens dust removal device.

[0005] To achieve the above objectives, this application adopts the following technical solution: a lens dust removal device, comprising a body: a lens dust removal device body is fixedly installed on the top of the body, a guide rail is fixed on the inner side of the body, the guide rail is two in number and is placed horizontally in a longitudinal direction, a slider is slidably installed inside the guide rail, a fixing plate is fixed on the top of the slider, an L-shaped plate is fixed on one side of the fixing plate, and an adaptive clamping mechanism for fixing the lens is provided on the inner side of the L-shaped plate.

[0010] Preferably, limit rods are fixed at both ends on the other side of the clamping plate, and limit holes are opened at both ends of the surface of the fixing plate, with the limit rods slidably installed inside the limit holes.

[0011] The technical effects and advantages of this utility model are as follows:

[0019] Based on the technical solution of this utility model, without changing the essential spirit of this utility model, those skilled in the art can propose various interchangeable structural methods and implementation methods. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model, and should not be regarded as the entirety of this utility model or as a limitation or restriction of the technical solution of this utility model.

[0020] Reference Figure 1 - Figure 4 As shown, this utility model provides a technical solution: a lens dust removal device, including a body 1: a lens dust removal device body 2 is fixedly installed on the top of the body 1, a guide rail 3 is fixed on the inner side of the body 1, there are two guide rails 3 and they are placed horizontally in the longitudinal direction, a slider 4 is slidably installed inside the guide rail 3, a fixing plate 5 is fixed on the top of the slider 4, an L-shaped plate 6 is fixed on one side of the fixing plate 5, and an adaptive clamping mechanism for fixing the lens is provided on the inner side of the L-shaped plate 6.

[0021] Specifically: The lens is dusted by the lens dust removal device body 2 on the top of the machine body 1. The adaptive clamping mechanism can clamp and fix lenses of different sizes, and can also adapt to and clamp irregularly shaped lenses, improving the stability of clamping and preventing the lens from shifting or being damaged during the dust removal process, which would affect the optical performance and service life of the lens. In addition, the cooperation of the guide rail 3 and the slider 4 can drive the adaptive clamping mechanism and the lens to move horizontally, which makes it easier for the lens dust removal device body 2 to remove dust from different positions of the lens, thus improving the efficiency and effect of dust removal.

[0022] Reference Figure 3 - Figure 4 As shown, in this embodiment: the adaptive clamping mechanism includes a fixed cylinder 7 fixed inside the L-shaped plate 6, a movable rod 8 sliding inside the fixed cylinder 7, a clamping plate 9 fixed at one end of the movable rod 8, a telescopic column 10 provided on one side of the clamping plate 9, the number of telescopic columns 10 being multiple and arranged longitudinally, a silicone suction cup 11 provided at the other end of the telescopic column 10, a first spring 12 sleeved on the surface of the telescopic column 10, one end of the first spring 12 being fixed to the clamping plate 9, and the other end of the first spring 12 being fixed to the telescopic end of the telescopic column 10, a pull rod 13 fixed on the surface of the movable rod 8 inside the fixed cylinder 7, a second spring 14 sleeved on the surface of the fixed cylinder 7, one end of the second spring 14 being fixed to the L-shaped plate 6, the pull rod 13 extending to the outside of the fixed cylinder 7 and higher than the second spring 14, and the pull rod 13 being located at the pitch of the second spring 14;

[0023] Specifically: Before dust removal, the operator manually pulls the lever 13, which causes the movable rod 8 to slide within the fixed cylinder 7. Simultaneously, the lever 13 on the movable rod 8 compresses the second spring 14. The movement of the movable rod 8 causes the clamping plate 9 to move, which in turn causes the telescopic column 10 and the silicone suction cup 11 to move. The telescopic column 10 compresses the first spring 12. At this point, the lens is placed between the two silicone suction cups 11. The lever 13 is then released. Under the action of the second spring 14, the movable rod 8 causes the clamping plate 9 to reset, which in turn causes the telescopic column 10 and the silicone suction cup 11 to reset. The telescopic column 10 resets under the action of the first spring 12, and the two silicone suction cups 11 clamp and fix the lens. The design of the clamping mechanism facilitates the fitting and clamping of lenses of different sizes and irregular shapes, improving the practicality of the device. At the same time, it avoids rigid contact that could cause the lens edge to crack or the surface to scratch.

[0024] Reference Figure 4 As shown in this embodiment: a guide groove 15 is provided on the surface of the fixed cylinder 7, and the pull rod 13 slides inside the guide groove 15;

[0025] Specifically: The guide groove 15 guides and limits the pull rod 13, so that the pull rod 13 can slide stably along the guide groove 15 when pulled, avoiding the pull rod 13 from deviating or shaking during the pulling process, and further improving the stability and accuracy of the adaptive clamping mechanism when clamping the lens.

[0026] Reference Figure 3 As shown in this embodiment: both ends of the clamping plate 9 are fixed with limit rods 16, and both ends of the surface of the fixing plate 5 are provided with limit holes 17, and the limit rods 16 are slidably installed inside the limit holes 17.

[0027] Specifically, the movement of the clamping plate 9 is guided and limited by the cooperation of the limiting rod 16 and the limiting hole 17, preventing the clamping plate 9 from deflecting or shaking during movement, thus further improving the stability and accuracy of clamping. At the same time, the setting of the limiting rod 16 and the limiting hole 17 also makes the clamping plate 9 move more smoothly, avoiding potential damage to the lens caused by shaking. In addition, this design simplifies the structure of the adaptive clamping mechanism, reduces manufacturing costs, and improves the practicality of the device.

[0028] Working principle: The user cleans the lens using the lens dust removal device body 2 on the top of the machine 1. During the dust removal process, the operator first manually pulls the lever 13 according to the size and shape of the lens. The lever 13 drives the movable rod 8 to slide inside the fixed cylinder 7. At the same time, the lever 13 compresses the second spring 14. The movement of the movable rod 8 further drives the clamping plate 9 to move. The movement of the clamping plate 9 drives the telescopic column 10 and the silicone suction cup 11 to move. During the movement, the telescopic column 10 compresses the first spring 12. At this time, the operator places the lens between the two silicone suction cups 11 and then releases the lever 13. Under the elastic force of the second spring 14, the movable rod 8 drives the clamping plate 9 to reset. The reset of the clamping plate 9 further drives the telescopic column 10 and the silicone suction cup 11 to reset. At the same time, the telescopic column 10 also resets under the elastic force of the first spring 12. Thus, the two silicone suction cups 11 firmly clamp and fix the lens.

[0029] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
