Description

Technical Field

[0001] This utility model relates to the field of wafer testing auxiliary equipment technology, and in particular to a gimbal for fixing a camera. Background Technology

[0002] Wafer testing equipment requires image acquisition devices to capture wafer images. At the camera mounting location, the entire wafer testing setup needs a system capable of high-precision adjustment and camera replacement during testing.

[0003] Existing technologies typically use simple camera mounts to fix cameras. These mounts suffer from low precision and poor stability, and require manual rotation to adjust the camera and lens position. This results in coarse adjustments, inconvenience, and a lack of ability to adjust for levelness. Therefore, there is a lack of a stable gimbal that supports fine, high-precision adjustments and allows for quick camera changes. Utility Model Content

[0004] This invention addresses the technical problems of existing simple camera brackets used for fixing cameras, which suffer from low precision, poor stability, and the need for manual rotation of the bracket to adjust the position of the camera and lens. These problems include coarse adjustment accuracy, inconvenience, and inability to adjust the level. The invention proposes a gimbal for fixing cameras that can adjust the overall level of the device, ensuring the stability, accuracy, and safety of the sample in the testing environment and preventing displacement of the sample during testing.

[0005] This utility model provides a gimbal for fixing a camera, including: a mounting base, a lower plate, an upper plate, a micrometer, a connecting plate, and a camera fixing plate;

[0006] The lower plate, upper plate, connecting plate, and camera fixing plate all have a center hole in the center;

[0007] The lower plate is fixed to the side wall of the mounting base;

[0008] A rotary bearing is movably installed in the center hole of the lower plate, and the upper part of the rotary bearing is fixedly connected to the upper plate.

[0009] Multiple fine-threaded bolts are distributed in the connecting plate, and the bottom of the fine-threaded bolts rests on the upper plate; the upper plate and the connecting plate are connected by multiple springs; a camera mounting plate is fixedly installed on the connecting plate;

[0010] A micrometer is installed at the end of the lower plate away from the mounting base;

[0011] The micrometer's screw is threaded to the lower plate, and the micrometer's screw is movably connected to the top post, which is fixedly connected to the bottom surface of the upper plate.

[0012] Preferably, the micrometer is mounted on the lower plate using a micrometer clamping device.

[0013] Preferably, the micrometer is a spring micrometer.

[0014] Preferably, a knob is provided on the top of the fine-threaded bolt.

[0015] This invention provides a gimbal for fixing a camera. By rotating a knob and using fine-threaded bolts in conjunction with spring tension, the distance between the upper plate and the connecting plate at various angles can be adjusted, thereby achieving the levelness of the upper plate and the connecting plate and ensuring the levelness of the device. The high-precision adjustment of the overall levelness of the device through the cooperation of the upper plate, connecting plate, spring, knob, and fine-threaded bolts ensures the stability, accuracy, and safety of the sample in the testing environment, preventing sample displacement during testing. High-precision adjustment using a rotating bearing, top column, and micrometer achieves matching between the camera lens and the sample. The camera fixing plate design allows for quick camera replacement. This invention features a compact design, simple structure, space-saving layout, convenient operation, high reliability, and ease of operation and maintenance. This invention enables rapid and stable adjustment and quick camera replacement, making it particularly suitable for testing wafer samples. Attached Figure Description

[0020] To make the technical problems solved by this utility model, the technical solutions adopted, and the technical effects achieved clearer, this utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining this utility model and not for limiting it. Furthermore, it should be noted that, for ease of description, only the parts related to this utility model are shown in the accompanying drawings, not all of them.

[0021] like Figure 1-3As shown in the figure, the present invention provides a gimbal for fixing a camera, comprising: a mounting base 1, a lower plate 2, an upper plate 3, a micrometer 4, a connecting plate 10, and a camera fixing plate 11.

[0022] Mounting base 1 provides fixation and support for the entire device. Mounting base 1 can be made of aluminum alloy, which is lightweight, high-strength, corrosion-resistant, and will not deform after long-term use.

[0023] The lower plate 2, upper plate 3, connecting plate 10, and camera fixing plate 11 all have a center hole, which allows the camera lens to pass through.

[0024] The lower plate 2 is fixed to the side wall of the mounting base 1; a rotary bearing 7 is movably installed in the center hole of the lower plate 2, and the upper plate 3 is fixedly connected above the rotary bearing 7; pushing the upper plate 3 can cause it and its components to rotate above the lower plate 2 by passing through the rotary bearing 7.

[0025] Multiple fine-threaded bolts 6 are distributed in the connecting plate 10, and the bottom of each fine-threaded bolt 6 rests on the upper plate 3. The upper plate 3 and the connecting plate 10 are connected by multiple springs 8. Specifically, the bottom of each spring 8 is fixed to the upper plate 3, and the top of each spring 8 is fixed to a spring hole in the connecting plate 10, where a crossbar for fixing the spring 8 is located. The springs 8 are made of high-strength spring steel, which has good elasticity and durability.

[0026] A knob 9 is provided on the top of the fine-threaded bolt 6. By rotating the knob 9 and the fine-threaded bolt 6, the extension degree of the fine-threaded bolt 6 can be adjusted. Three fine-threaded bolts 6 can be provided and distributed at the three corners of the connecting plate 10. By adjusting the three fine-threaded bolts 6, the tension of the spring 8 adapts to the change, thereby adjusting the tension of the spring 8. This allows for adjustment of the distance between the upper plate 3 and the connecting plate 10 at each corner, thus achieving the adjustment of the levelness between the upper plate 3 and the connecting plate 10 and ensuring the levelness of the device.

[0027] A camera mounting plate 11 is fixedly mounted on the connecting plate 10. The camera mounting plate 11 has threaded holes, which can be used to fix the camera to the camera mounting plate 11, allowing for quick camera replacement. The camera is positioned with its face downwards, and the lens passes through the center hole of each plate.

[0028] A micrometer 4 is mounted on the lower plate 2 at the end furthest from the mounting base 1. The screw 13 of the micrometer 4 is threadedly connected to the lower plate 2. Specifically, a threaded hole is provided on the side wall of the protruding end of the lower plate 2, and the screw 13 is screwed into the thread. The screw 13 of the micrometer 4 is movably connected to the top post 5, and the top post 5 is fitted onto the screw 13. The top post 5 is fixedly connected to the upper plate 3. The top post 5 is made of aluminum alloy. Specifically, the micrometer 4 is mounted on the lower plate 2 via a micrometer clamping member 12. The micrometer 4 is a spring-loaded micrometer. By rotating the micrometer 4, the screw 13 can drive the top post 5 to move left and right, thereby pushing the upper plate 3 through the top post 5, achieving a slight rotation of the upper plate 3 and its components, that is, a slight rotation of the camera and lens mounted on the camera mounting plate 11.

[0029] The lower plate 2 provides a stable foundation. The upper plate 2, lower plate 3, knob 9, connecting plate 10, and camera mounting plate 11 can be made of aluminum alloy, which is lightweight, high-strength, corrosion-resistant, and will not deform after long-term use. The surfaces of the upper plate 2 and lower plate 3 are finely ground and polished to reduce surface roughness and improve the stability of sample placement.

[0030] This utility model discloses a gimbal for fixing a camera. By rotating the knob 9 and the fine-threaded bolt 6 in conjunction with the tension of the spring 8, the distance between the upper plate 3 and the connecting plate 10 at each angle can be adjusted, thereby achieving the levelness of the upper plate 3 and the connecting plate 10 and ensuring the levelness of the device. The high-precision adjustment of the overall levelness of the device through the cooperation of the upper plate 3, the connecting plate 10, the spring 8, the knob 9, and the fine-threaded bolt 6 ensures the stability, accuracy, and safety of the sample in the testing environment, preventing sample displacement during testing. High-precision adjustment through the rotation bearing 7, the top column 5, and the micrometer 4 achieves the matching of the camera lens and the sample. The camera fixing plate 11 is designed for quick camera replacement. This utility model has a compact design, simple structure, saves space, is easy to operate, and has high reliability, facilitating operation and maintenance.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it; although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications to the technical solutions described in the foregoing embodiments, or equivalent substitutions for some or all of the technical features, do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
