Description

Technical Field

[0002] In the field of optics, the adjustment mechanism of optical lenses plays a crucial role in optimizing image quality and optical performance. Traditional optical lens adjustment mechanisms have many limitations, making it difficult to meet the diverse demands of modern optical systems for precise focusing and flexible movement. On the one hand, the focusing function of many traditional devices relies on manual operation, using mechanical parts such as knobs or screws for fine-tuning. This method is not only cumbersome to operate but also has limited adjustment precision, making it difficult to achieve high-precision optical lens position adjustment, especially in scenarios requiring frequent focusing or minute distance adjustments. On the other hand, once the optical lens assembly in some devices is installed, subsequent replacement and maintenance are extremely inconvenient. Lens disassembly often requires complex tools and tedious steps, which not only increases maintenance and time costs but may also damage the lenses during disassembly and assembly, affecting the stability and reliability of the optical system.

[0003] Therefore, in order to overcome the shortcomings of traditional optical mirror adjustment devices and improve the accuracy, flexibility, stability, and convenience of optical mirror adjustment, it is necessary to develop a new type of optical mirror movement adjustment device.

[0029] 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.

[0030] It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this utility model can be combined with each other.

[0031] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.

[0032] Example

[0033] This embodiment provides a movement adjustment device for an optical mirror, including: a support frame 1, a drive mechanism 2, a focusing lens assembly 3, and a moving lens assembly 4. These components work together to achieve precise axial movement adjustment of the optical mirror and flexible adjustment of the focal length, in order to meet the needs of different optical application scenarios.

[0034] The support frame 1 serves as the basic structure of the entire device and includes: two fixed plates 11, two guide rods 12, a movable lens mounting component 13, and a focusing lens mounting component 14; the two fixed plates 11 are arranged opposite each other and are located on both sides of the device, playing a role in stabilizing and supporting the entire structure.

[0035] Two guide rods 12 are fixedly installed on the top sides of the fixed plate 11 respectively, and their two ends are fixedly connected between the two fixed plates 11, thus forming a stable frame structure; the two ends of the movable lens mounting piece 13 are slidably sleeved on the outer surface of the guide rod 12, which allows the movable lens mounting piece 13 to move axially on the guide rod 12, providing a basis for the position adjustment of the movable lens assembly 4.

[0036] The focusing lens mounting component 14 is fixedly installed on the end of the guide rod 12 away from the moving lens mounting component 13. The upper part of the focusing lens mounting component 14 has a receiving cavity, in which the focusing lens assembly 3 is embedded. To facilitate the installation and fixation of the focusing lens assembly 3, an arc-shaped clamping plate 15 is hinged to one side of the top of the focusing lens mounting component 14. A connecting plate 151 is connected to the side of the arc-shaped clamping plate 15 away from the hinge end. A first threaded hole is opened on the connecting plate 151 along the thickness direction. Correspondingly, a second threaded hole 142 is opened on the other side of the top of the focusing lens mounting component 14. Through the cooperation of bolts and threaded holes, the focusing lens assembly 3 can be firmly locked in the receiving cavity. This design not only facilitates the installation and disassembly of the focusing lens assembly 3, but also ensures its stability during use, providing a reliable guarantee for the focusing operation of the optical lens.

[0037] The movable lens assembly 4 includes a lens frame 41 and several lens assemblies 42. The lens frame 41 is fixedly installed on the upper part of the movable lens mounting part 13 and is coaxially arranged with the focusing lens assembly 3 to ensure accurate light transmission. The lens frame 41 has a through hole 4111 along the axial direction, and a plurality of placement openings 411 are spaced apart along the axial direction on its upper side wall. These placement openings 411 are connected to the through hole 4111 to form a mounting cavity. The lens assemblies 42 are detachably installed in the mounting cavity through the placement openings 411, which facilitates the replacement and maintenance of the lens assemblies 42 according to actual needs.

[0038] The lens assembly 42 consists of a lens frame 421 and a lens 423. The lens frame 421 has an axial mounting hole, and the lens 423 is fixedly installed in the mounting hole. The lens frame 421 can be placed in the placement opening 411 of the lens frame 41. In order to limit the axial position of the lens frame 421 in the mounting cavity of the lens frame 41, multiple arc-shaped limiting grooves 412 are opened on the inner wall of the through hole 4111 of the lens frame 41, corresponding to each placement opening 411. An arc-shaped limiting plate 422 adapted to the arc-shaped limiting groove 412 is fixedly provided at the bottom of the lens frame 421. When the arc-shaped limiting plate 422 is inserted into the arc-shaped limiting groove 412, the axial position of the lens frame 421 can be limited, ensuring the stability of the lens assembly 42 in the moving lens assembly 4.

[0039] In addition, an arc-shaped handle 413 is fixedly installed on the upper part of the mirror frame 41, and the surface of the arc-shaped handle 413 is provided with anti-slip texture to facilitate the operator to grab and move the mirror frame 41, thereby improving the convenience and safety of operation.

[0040] The drive mechanism 2 uses a servo motor, which is fixedly mounted on one of the two fixed plates 11. The servo motor is electrically connected to the PLC controller, which facilitates precise control of the drive mechanism 2. The output end of the drive mechanism 2 is connected to a threaded drive rod 21. The end of the threaded drive rod 21 away from the drive mechanism 2 is mounted on the other fixed plate 11 through a rotating shaft seat, ensuring that the threaded drive rod 21 can rotate stably. A nut is rotatably sleeved on the outer surface of the threaded drive rod 21. The nut is fixedly connected to the bottom of the movable lens mounting part 13. When the drive mechanism 2 works and drives the threaded drive rod 21 to rotate, the nut will move along the threaded drive rod 21, thereby driving the movable lens mounting part 13 to move on the guide rod 12, realizing the axial displacement adjustment of the movable lens assembly 4. This driving method can precisely control the position of the movable lens assembly 4, thereby realizing the focusing of the optical lens and meeting different optical imaging requirements.

[0041] A placement plate 141 is also fixedly installed at the bottom of the focusing lens mounting component 14, which can be used to place some tools or parts related to focusing operation, making it convenient to use during the focusing process and improving the practicality of the device.

[0042] In actual use, the focusing lens assembly 3 is first installed in the receiving cavity of the focusing lens mounting part 14, and is firmly locked by the cooperation of the arc-shaped clamp 15, the connecting plate 151, and the bolts and threaded holes; then, the lens assembly 42 is installed in the mounting cavity of the lens frame 41 through the placement port 411, and the lens assembly 42 is axially limited by the cooperation of the arc-shaped limiting plate 422 and the arc-shaped limiting groove 412 to ensure the stability of its installation.

[0043] When focusing of the optical mirror is required, the controller sends a command to the servo motor, which starts and drives the threaded drive rod 21 to rotate. The nut moves on the threaded drive rod 21, which in turn drives the movable lens mounting part 13 to move along the guide rod 12, thereby changing the relative position between the movable lens assembly 4 and the focusing lens assembly 3, thus realizing the focusing function of the optical mirror. During the focusing process, the operator can grab and replace the lens assembly 42 with the arc-shaped handle 413 according to actual needs, thereby achieving the best optical imaging effect.

[0044] In summary, this invention provides a stable mounting foundation for all components through a support frame. The servo motor-driven threaded transmission mechanism precisely controls the movement of the moving lens assembly. Combined with the detachable focusing lens assembly and the moving lens assembly, it not only facilitates focusing of the optical mirror and the replacement and maintenance of lens components, but also ensures the stability and image quality of the optical mirror during use. The overall structure is rationally designed and easy to operate, providing an efficient and precise solution for the debugging and use of optical equipment.

Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of this utility model should be included within the protection scope of this utility model.
