Description

Technical Field

[0001] This utility model relates to the field of microcylindrical mirror production technology, specifically a coating clamping fixture suitable for microcylindrical mirrors. Background Technology

[0002] Microcylindrical mirrors are aspherical lenses that effectively reduce spherical aberration and chromatic aberration, and also offer some magnification. They have a wide range of applications, including linear detector illumination, barcode scanning, holographic illumination, optical information processing, computers, and laser emission, primarily for resizing images. LiDAR is widely used in autonomous driving, unmanned warehouses, logistics, and other applications, and as devices become increasingly miniaturized, cylindrical mirrors are a crucial component of LiDAR systems.

[0003] During the production of microcylindrical mirrors, it is necessary to coat the cylindrical surfaces. Coating the entrance and exit surfaces of the lens can increase the optical performance of the operating wavelength by about 6%. At the same time, it is important to ensure that the optical surface quality is not affected before and after coating. Coating clamping and cleaning are particularly important. The traditional method is to clean the lens and arrange it on a fixture, coat the first surface, take it out and clean the second surface, and then arrange it on the same fixture for coating. In this way, the evaporated material is coated on both sides of the microcylindrical mirror.

[0004] The reference patent number "CN221501229U" entitled "A Coating Clamping Fixture Suitable for Microcylindrical Mirrors" addresses the issues of "microcylindrical mirrors being small, slender, and brittle, leading to rapid temperature increases during evaporation coating, causing them to expand and break at high temperatures, and poor coating results due to difficulty in contact between the clamping point and the evaporating material." However, it also has some drawbacks. For example, the clamping angle of the microcylindrical mirror in the aforementioned application is fixed and cannot be adjusted, resulting in a small coating space on the bottom surface of the microcylindrical mirror, which can easily lead to uneven coating on both sides of the microcylindrical mirror, affecting its coating effect. Furthermore, the aforementioned application can only clamp microcylindrical mirrors of the same specification during the coating process; when coating microcylindrical mirrors of other specifications and sizes, the fixture needs to be changed, which is inconvenient. Therefore, a coating clamping fixture suitable for microcylindrical mirrors is proposed to solve the aforementioned technical problems. Utility Model Content

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, this utility model provides a coating clamping fixture suitable for micro cylindrical mirrors, which has the following beneficial effects:

[0015] This coating clamping fixture for microcylindrical mirrors is designed with a support base, support plate, drive motor, U-shaped connecting frame, coating fixing frame, moving cross groove, coating support rod, and locking block. During use, the operator can choose to start the drive motor to rotate the U-shaped connecting frame and coating fixing frame to adjust the coating clamping angle of the microcylindrical mirror or flip it for double-sided uniform coating, depending on the coating requirements. After double-sided coating, the operator can move the coating support rod to lock the coating fixing frame in place for observation and inspection.

It is highly practical. Through the coordination of the limit groove and mounting screws, the operator can position and install this coating clamping fixture suitable for microcylindrical mirrors as needed, improving the stability of the microcylindrical mirror coating.

A support plate 2 is fixedly connected to the upper surface of the support base 1. A drive motor 3 is fixedly connected to the outer wall of the support plate 2. A U-shaped connecting frame 4 is fixedly connected to the output end of the drive motor 3. A coating fixing frame 5 is fixedly connected to the inner wall of the U-shaped connecting frame 4. Two microcylindrical mirror coating slots 6 are formed on the surface of the coating fixing frame 5. Through the coordinated arrangement of the microcylindrical mirror coating slots 6, servo motor 7, bidirectional screw 8, limit moving block 9, limit clamping frame 10, and anti-slip silicone block 11, the operator can rotate the bidirectional screw 8 left and right by starting the servo motor 7, causing the limit moving block... 9 drives the limiting clamping frame 10 to move relative to the surface of the bidirectional screw 8 until the anti-slip silicone block 11 is fixed to the side surface of the micro cylindrical mirror of different sizes, thus playing the role of anti-slip clamping for micro cylindrical mirrors of different sizes during the coating process. It is highly practical. The left and right ends of the coating fixing frame 5 are fixedly connected to the servo motor 7 on one side of the coating groove 6 of the micro cylindrical mirror. The output end of the servo motor 7 is fixedly connected to the bidirectional screw 8. The two sections of the surface of the bidirectional screw 8 with opposite directions of threaded grooves are threadedly connected to the limiting moving block 9. The inner side wall of the limiting moving block 9 is fixedly connected to the limiting clamping frame 10. The inner side wall of the limiting clamping frame 10 is fixedly connected to the anti-slip silicone block 11. The top four corners of the support base 1 are all provided with moving blocks. The transverse groove 12 is slidably connected to a coating support rod 13. A snap-fit ​​block 14 is fixedly connected to the top of the coating support rod 13. Limiting grooves 15 are opened on the inner sidewalls of the two micro-cylindrical mirror coating slots 6. Through the cooperation of the limiting grooves 15 and the mounting screws 16, the operator can position and install the coating clamping fixture suitable for micro-cylindrical mirrors as needed, which improves the stability of micro-cylindrical mirror coating.

[0021] In summary, this coating clamping fixture for microcylindrical mirrors, through the coordinated arrangement of a support base 1, support plate 2, drive motor 3, U-shaped connecting frame 4, coating fixing frame 5, moving transverse groove 12, coating support rod 13, and locking block 14, allows the operator to select and start the drive motor 3 to rotate the U-shaped connecting frame 4 and coating fixing frame 5 to adjust the coating clamping angle of the microcylindrical mirror or to flip it for double-sided uniform coating, as needed. After double-sided coating, the operator can move the coating support rod 13 to drive the locking block 14 to clamp and fix the coating fixing frame 5 for observation and inspection. This fixture facilitates the flipping or angle adjustment of the microcylindrical mirror during the coating process, enabling the operator to perform double-sided uniform coating on the microcylindrical mirror and allowing for convenient operation of the microcylindrical mirror as needed. After coating, the mirror is fixed for easy inspection. The fixture is designed with a coating groove 6 for the micro-cylindrical mirror, a servo motor 7, a bidirectional screw 8, a limiting moving block 9, a limiting clamping frame 10, and an anti-slip silicone block 11. During use, the operator can start the servo motor 7 to rotate the bidirectional screw 8 left and right. This causes the limiting moving block 9 to move relative to the limiting clamping frame 10, which is threaded and limited relative to the surface of the bidirectional screw 8 until the anti-slip silicone block 11 secures the micro-cylindrical mirrors of different sizes to the side surface. This provides anti-slip clamping for micro-cylindrical mirrors of different sizes during the coating process, making it highly practical. The limiting groove 15 and the mounting screw 16 allow the operator to position and install the coating clamping fixture suitable for micro-cylindrical mirrors as needed, improving the stability of the micro-cylindrical mirror coating.
