[0034] Example

[0035] A fixture for coating optical components, such as Figure 1-Figure 5 Shown, including:

[0036] Base plate 1 with mounting ring 2;

[0037] A plurality of size adjustment mechanisms 4 are connected through the mounting ring 2;

[0038] Multiple clamping mechanisms 3 are connected to the inner ends of corresponding size adjustment mechanisms 4. The clamping mechanisms 3 are slidably connected to the substrate 1. The size adjustment mechanisms 4 drive the clamping mechanisms 3 to slide to change the size of the clamping spaces between the multiple clamping mechanisms 3.

[0039] The size adjustment mechanism 4 and the clamping mechanism 3 are provided in greater than 3 groups, preferably 4 groups;

[0040] The clamping mechanism 3 has a clamping pad 303 .

[0041] When the present invention is in use, the optical element to be coated is placed in the clamping space formed by the multiple clamping mechanisms 3 inside the substrate 1. The size adjustment mechanism 4 drives the clamping mechanism 3 to move, and the size of the clamping space is changed, thereby adapting to the fixation of optical elements of different sizes. At the same time, since the optical element is clamped by the clamping pad 303, the deformation of the clamping pad 303 itself can be used to adapt to optical elements of different shapes, such as Figure 1 and Figure 2As shown, square and circular optical elements are clamped and fixed respectively. The clamping pad 303 can be transformed from a straight line to an arc shape by its own deformation, and the curvature can be changed. Therefore, the utility model is suitable for fixing optical elements of different sizes and shapes, has strong versatility, does not require frequent replacement of fixtures, and is conducive to improving production efficiency.

[0042] In one or more examples of the present invention, Figure 3 As shown, the size adjustment mechanism 4 includes a screw 402 and a translation sleeve 401. The screw 402 is rotatably connected to the mounting ring 2. The translation sleeve 401 is threadedly connected to the screw 402. The inward end of the translation sleeve 401 is connected to the clamping mechanism 3. The outer wall of the translation sleeve 401 is slidably connected to the inner wall of the through-slot defined in the mounting ring 2. When securing optical components of different sizes, rotating the screw 402 drives the translation sleeve 401 to move linearly via the thread, thereby driving the clamping mechanism 3 to move, thereby adjusting the size of the clamping space to accommodate optical components of different sizes.

[0043] Specifically, a second slider 405 is provided on the outer wall of the translation sleeve 401, and a second slide groove 404 is provided on the inner wall of the through-slot provided in the mounting ring 2. The second slider 405 slides in conjunction with the second slide groove 404. The second slide groove 404 and the second slider 405 limit the movement of the translation sleeve 401, thereby achieving linear motion of the translation sleeve 401.

[0044] As a preferred embodiment, the end of the screw rod 402 away from the translation sleeve 401 passes through the through slot provided in the mounting ring 2 and is connected to the end handle 403. The end handle 403 can be provided to facilitate the user to rotate the screw rod 402.

[0045] In one or more examples of the present invention, a leaf spring 304 is provided inside the clamping pad 303. The leaf spring 304 facilitates elastic deformation to accommodate optical elements of different shapes, and also provides a certain degree of rigidity for the clamping pad 303, ensuring that the clamping pad 303 performs a good clamping function.

[0046] In one or more examples of the present invention, the clamping mechanism 3 includes a mounting plate 301 and mounting side plates 302. The mounting side plates 302 are provided on either side of the mounting plate 301, and the ends of the clamping cushion 303 are fixedly connected to the mounting side plates 302 on either side. The mounting plate 301 facilitates the fixing of the clamping mechanism 3, while the mounting side plates 302 are provided to facilitate the fixing of the ends of the clamping cushion 303, enabling the clamping cushion 303 to provide a good clamping force.

[0047] As a preferred embodiment, the clamping mechanism 3 further includes a pull rod 305, which is fixedly connected to the side of the clamping cushion 303 facing the size adjustment mechanism 4. The pull rod 305 can be provided to pull the clamping cushion 303, facilitating deformation by utilizing the elasticity of the clamping cushion 303 and the leaf spring 304, thereby adapting to the clamping and fixing of optical components of different shapes.

[0048] As a further preferred embodiment, the end of the pull rod 305 away from the clamping cushion 303 is further provided with an end handle 306. The end handle 306 is provided to facilitate the user to pull the pull rod 305.

[0049] As a further preferred embodiment, the clamping mechanism 3 further includes a support base plate 307 and a bottom cushion 308. The support base plate 307 is disposed at the bottom of the mounting base plate, and the bottom cushion 308 is fixed to the upper surface of the mounting base plate. The support base plate 307 facilitates placement of the optical element to be coated, while the bottom cushion 308 provides protection for the optical element.

[0050] In the present invention, the clamping pad 303 and the bottom pad 308 can be made of any elastic material, such as polytetrafluoroethylene.
