[0032] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0033] In this utility model, unless otherwise stated, directional terms such as "upper," "lower," "top," and "bottom" are generally used in relation to the direction shown in the accompanying drawings, or in relation to the vertical, perpendicular, or gravitational direction of the component itself; similarly, for ease of understanding and description, "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0034] The main objective of this invention is to provide a carrier structure for optical elements, thereby solving the problem that existing carrier structures for optical elements are prone to causing damage to the optical elements.

[0035] Example 1

[0036] like Figures 1 to 9 As shown, the carrier structure for the optical element includes a support, a clamping component 4, a leveling and positioning component 5, and an anti-rotation component 6. One side of the support has a recess. The clamping component 4 is disposed in the recess and includes a first cover plate 41 and a second cover plate 42 stacked together. The first cover plate 41 is located on the side of the second cover plate 42 away from the support. The surfaces of the first cover plate 41 and the second cover plate 42 facing each other have a receiving area for accommodating the optical element 7. The leveling and positioning component 5 is disposed between the clamping component 4 and the bottom of the recess, and is used to adjust the angle and position of the clamping component 4 on the support. The anti-rotation component 6 is disposed on the clamping component 4 and located around the receiving area. The anti-rotation component 6 has a limiting portion 611 extending toward the receiving area, which limits the rotation of the optical element 7.

[0037] One side of the support has a recessed groove, in which the clamping component 4 is positioned. This provides space for the clamping component 4, facilitating its quick installation on the support and ensuring its stability. The clamping component 4 includes a first cover plate 41 and a second cover plate 42 stacked together. The surfaces of the first cover plate 41 and the second cover plate 42 facing each other have accommodating areas for the optical element 7, thus defining its placement and protecting it from external contaminants and dust. The leveling and positioning component 5 adjusts the angle of the clamping component 4 relative to the support, ensuring its horizontal installation on the support and guaranteeing the levelness of the optical element 7 for subsequent testing. Furthermore, the leveling and positioning component 5 facilitates quick positioning and installation of the clamping component 4 on the support, ensuring its positional reliability and overall structural reliability. By setting the anti-rotation component 6, the anti-rotation component 6 can limit the optical element 7, preventing the optical element 7 from rotating when subjected to external vibration or gravity, thereby avoiding damage caused by the rotation of the optical element 7 and helping to ensure the stability of the optical element 7.

[0038] In summary, the carrier structure for the optical element of this application not only effectively protects the optical element 7 during clamping and inspection, thus significantly reducing the risk of scratches, but also possesses efficient and accurate positioning capabilities, which helps improve production efficiency and product reliability, thereby enhancing the safety and efficiency of the inspection process for the optical element 7.

[0039] like Figure 1 and Figure 2 As shown, the support includes a base 1, a support plate 2, and a bottom plate 3. The base 1 has a groove structure with a through hole at the bottom. The support plate 2 is placed in the groove structure and is fixedly connected to the base 1 by screws. The support plate 2 also has a through hole in the middle, which corresponds to the through hole in the base 1. The bottom plate 3 is placed on the support plate 2 and fixedly connected by screws. The bottom plate 3 has a recess, and a clamping component 4 is placed in the recess of the bottom plate 3. A leveling and positioning component 5 is placed between the second cover plate 42 and the bottom plate 3. By designing the support into a multi-layer plate structure, the leveling and positioning component 5 can be used for fine-tuning between the second cover plate 42 and the bottom plate 3 to achieve multi-dimensional adjustment of the optical element 7, thereby ensuring the angle of the optical element 7 relative to the support.

[0040] Specifically, the second cover plate 42 has a receiving groove on its surface facing the first cover plate 41. At least a portion of the first cover plate 41 is received in the receiving groove. The size of the first cover plate 41 is smaller than the size of the second cover plate 42. The projection of the first cover plate 41 onto the second cover plate 42 is within the second cover plate 42. The edge of the projection of the first cover plate 41 onto the second cover plate 42 is spaced apart from the edge of the second cover plate 42, so that at least a portion of the second cover plate 42 avoids the first cover plate 41. That is, the peripheral portion of the second cover plate 42 extends outward from the periphery of the first cover plate 41. Viewed from one side of the first cover plate 41, a portion of the second cover plate 42 on the outer periphery of the first cover plate 41 can be seen. By partially embedding the first cover plate 41 into the receiving groove of the second cover plate 42, not only is the connection between the two cover plates strengthened, but the outward extension of the peripheral portion of the second cover plate 42 also forms additional structural support, improving the overall strength and resistance to external impacts. Part of the second cover plate 42 is visible on one side of the first cover plate 41. This means that during inspection or operation, the portion of the second cover plate 42 on the outer periphery of the first cover plate 41 can be directly seen without completely disassembling or moving the first cover plate 41. This facilitates quick identification and adjustment of the position and status of the optical element 7 by inspection personnel or automated inspection equipment, improving inspection efficiency. The size difference between the first cover plate 41 and the second cover plate 42 allows the second cover plate 42 to provide additional space for integrating more functional components, such as the aforementioned leveling and positioning component 5 and anti-rotation component 6, without affecting the operation of the first cover plate 41 or the positioning of the optical element 7. This increases the design flexibility and functional versatility of the carrier structure.

[0041] In a specific embodiment of this application, the cross-sectional shape of the second cover plate 42 along the direction parallel to it is quadrilateral, and the cross-sectional shape of the first cover plate 41 along the direction parallel to it is circular. However, in other optional embodiments of this application, the shapes of the second cover plate 42 and the first cover plate 41 can be set in other shapes, and this application is not limited thereto. It should be noted that the above-mentioned receiving area is actually a groove provided on the surface of the first cover plate 41 facing the second cover plate 42; or a groove provided on the surface of the second cover plate 42 facing the first cover plate 41; or both the first cover plate 41 and the second cover plate 42 have grooves on their respective facing surfaces, and the two grooves form the receiving area. Figure 2 As can be seen, the thickness of the accommodating area is very small.

[0042] In addition, in this application, the plate portions of the first cover plate 41 and the second cover plate 42 corresponding to the receiving area are transparent plates, which facilitates observation of the state of the optical element 7 in the receiving area.

[0043] like Figure 1 and Figure 2As shown, a first handle 43 is provided on the surface of the first cover plate 41 away from the support, and a second handle 44 is provided on the surface of the second cover plate 42 away from the support. In a preferred embodiment of this application, there are two first handles 43, both located at the edge of the surface of the first cover plate 41 away from the second cover plate 42, and the angle between the lines connecting the two first handles 43 to the center point of the first cover plate 41 is 180°. In a preferred embodiment of this application, there are two second handles 44, both located at the edge of the surface of the second cover plate 42 away from the support, and the angle between the lines connecting the two second handles 44 to the center point of the second cover plate 42 is 180°, and the two second handles 44 are located in the area not covered by the projection of the first cover plate 41. This arrangement, with the first handles 43 and the second handles 44, allows for flexible assembly and disassembly of the clamping component 4 from the base plate 3, as well as the flexible assembly and disassembly of the first cover plate 41 from the second cover plate 42, improving operational convenience.

[0044] like Figure 3 As shown, Figure 3 It shows Figure 1 A cross-sectional view of the clamping component along the BB direction shows that the first cover plate 41 and the second cover plate 42 are magnetically connected. A magnet 45 is embedded in the surface of the first cover plate 41 facing the second cover plate 42, and a corresponding magnetic ring structure 46 (specifically, an iron ring structure) is embedded in the second cover plate 42. Both the magnet 45 and the magnetic ring structure 46 are located on the outer periphery of the receiving area. The magnetic connection between the magnet 45 and the magnetic ring structure 46 achieves the magnetic connection between the first cover plate 41 and the second cover plate 42. This facilitates flexible cooperation between the first cover plate 41 and the second cover plate 42, making operation convenient and suitable for applications requiring frequent replacement of the optical element 7. To reduce the weight of the entire vehicle structure, the first cover plate 41 and the second cover plate 42 are usually not made of iron. Therefore, this application sets a magnet 45 and a magnetic ring structure 46 so that when the first cover plate 41 is placed on the second cover plate 42, the two will automatically attract each other and clamp the optical element 7. This allows the optical element 7 to be clamped between the first cover plate 41 and the second cover plate 42, and the operation is convenient. At the same time, by selecting a magnet 45 with an appropriate attraction force, damage to the optical element 7 can be effectively avoided.

[0045] like Figure 1As shown, there are multiple leveling and positioning components 5, which are arranged circumferentially around the clamping component 4. At least two leveling and positioning components 5 are located on the edge of the first side of the clamping component 4, and at least one leveling and positioning component 5 is located on the edge of the second side of the clamping component 4. The first and second sides of the clamping component 4 are opposite sides of the clamping component 4. In a specific embodiment of this application, the multiple leveling and positioning components 5 are arranged circumferentially around the second cover plate 42, and the leveling and positioning components 5 are located in positions not covered by the projection of the first cover plate 41. One leveling and positioning component 5 is located at each of the two corners of the first side of the second cover plate 42, and another leveling and positioning component 5 is located at the middle position of the second side of the second cover plate 42. The first and second sides of the second cover plate 42 are opposite sides, and the lines connecting the three leveling and positioning components 5 can form a triangle. Through multi-point leveling and positioning, the flatness and tilt of the optical element 7 can be controlled more precisely, which is suitable for optical elements 7 requiring high-precision alignment, such as lenses and mirrors.

[0046] like Figure 4 and Figure 6 As shown, Figure 4 It shows Figure 1 A cross-sectional view in the CC direction of the leveling and positioning component 5 located at one corner of the first side of the second cover plate 42. The leveling and positioning components 5 located at the two corners of the first side of the second cover plate 42 can realize the positioning adjustment of the clamping component 4 in the Y-axis direction. Specifically, the leveling and positioning component 5 includes a first adjusting seat 51, a second adjusting seat 52, and an adjusting screw 53. The first adjusting seat 51 is disposed on the bottom of the sink, specifically, the first adjusting seat 51 is embedded in the base plate 3. The first adjusting seat 51 has a groove 511 on the side facing the clamping component 4; the second adjusting seat 52 is disposed on the clamping component 4, specifically on the second cover plate 42 and connected to the second cover plate 42 by screws. The second adjusting seat 52 is disposed opposite to the first adjusting seat 51 and has a threaded hole through it; the adjusting screw 53 engages with the threaded hole, and the adjusting screw 53 is screwed into the threaded hole from the side of the second adjusting seat 52 away from the first adjusting seat 51, and screwed out from the threaded hole toward the groove 511. The end of the adjusting screw 53 extending from the threaded hole contacts the groove 511. This arrangement, through the contact between the adjusting screw 53 and the groove 511, makes the groove 511 play a guiding and positioning role, positioning the clamping component 4 in one direction.

[0047] Furthermore, by adjusting the engagement between screw 53 and groove 511, and by changing the screw-in depth of screw 53, fine-tuning of the angle and position of optical element 7 can be achieved. This mechanism provides crucial support for experiments requiring high-precision optical path adjustment, such as quantum computing and fiber optic sensing. Its simple operation and high accuracy significantly improve experimental preparation efficiency and data reliability.

[0048] Specifically, the second adjusting seat 52 is installed through the second cover plate 42, and the adjusting end of the adjusting screw 53 is located on the side of the second cover plate 42 away from the bearing seat. This arrangement makes the operation of the adjusting screw 53 more convenient and allows the operator to flexibly control the screwing depth of the adjusting screw 53.

[0049] like Figure 5 and Figure 6 As shown, Figure 5 It shows Figure 4 A schematic diagram of the first adjusting seat 51 in the middle. Figure 6 It shows Figure 4 The first adjusting seat 51 has a top view of one side surface of a groove 511. The groove 511 is strip-shaped, and the cross-section of the strip-shaped groove 511 along the direction perpendicular to the bearing seat is V-shaped. Moreover, the bottom of the V-shaped groove 511 is rounded and not a sharp-cornered structure.

[0050] like Figure 7 As shown, Figure 1 The image shows a cross-sectional view of the leveling and positioning component 5 located at the middle position on the second side of the second cover plate 42 in the DD direction. This leveling and positioning component 5 is used to achieve positioning adjustment of the clamping component 4 in the X-axis direction. The extending direction of the groove 511 of the leveling and positioning component 5 located at the middle position on the second side of the second cover plate 42 is perpendicular to the extending direction of the grooves 511 of the leveling and positioning components 5 located at the two corner positions on the first side of the second cover plate 42.

[0051] In addition, refer to Figure 4 As shown, the leveling and positioning component 5 also includes a side set screw 54. After all three leveling and positioning components 5 have been adjusted, the side set screw 54 is screwed into the base plate 3 from the side and contacts the outer peripheral side of the first adjusting seat 51 to limit the first adjusting seat 51 and fix the first adjusting seat 51, thereby preventing the risk of the first adjusting seat 51 shaking and enhancing the stability of the leveling and positioning. It is suitable for occasions where adjustments need to be made in a narrow space.

[0052] like Figure 1 , Figure 8 and Figure 9 As shown, Figure 8 It shows Figure 1 A cross-sectional view of the anti-rotation component 6 in the EE direction. Figure 9 It shows Figure 1 Enlarged view at point I. The anti-rotation component 6 also includes an anti-rotation pressure block 61, which is detachably connected to the second cover plate 42 of the clamping component 4 via a fixing member 62, specifically a screw. The anti-rotation pressure block 61 has a limiting part 611 on the side facing the receiving area, and the limiting part 611 is a protruding structure. The outer peripheral surface of the optical element 7 has a small groove that mates with the protruding structure. The rotation of the optical element 7 is restricted by the engagement of the protruding structure with the small groove. The size of the protruding structure can be reasonably adjusted according to the depth of the small groove of the optical element 7 to ensure that the protruding structure can extend into the small groove.

[0053] Example 2

[0054] like Figure 10 As shown, the carrier structure of the optical element in Embodiment 2 is described.

[0055] The difference between this embodiment and Embodiment 1 is that this embodiment adds a supporting rib 8 based on Embodiment 1.

[0056] Specifically, the carrier structure also includes supporting ribs 8, which are in a grid pattern and are disposed within the clamping component 4. Specifically, they can be disposed in the receiving area, or in the structural portions of the first cover plate 41 and the second cover corresponding to the receiving area. By providing supporting ribs 8, the structural strength of the clamping component 4 is enhanced, ensuring its structural stability. This embodiment is primarily designed for large optical elements 7. The large size of the optical element 7 results in a large receiving area in the middle of the clamping component 4, which can easily lead to sagging in the middle portion of the clamping component 4, affecting detection accuracy and potentially damaging the optical element 7. Therefore, this embodiment adds supporting ribs 8 to improve the strength of the middle portion of the clamping component 4, preventing sagging of the optical element 7 and ensuring the stability and accuracy of the optical element 7 during the detection process. Of course, supporting ribs 8 may not be necessary for medium-sized or smaller optical elements 7.
