Description

Technical Field

[0001] This utility model relates to the field of digital slicing technology, specifically to an angle fine-tuning device used in digital slicing scanning. Background Technology

[0002] Digital slides, also known as virtual slides, are a medical technology that transforms traditional glass slides into high-resolution digital images using whole-slide scanning. Its core is an ultra-high-resolution image containing complete lesion information, supporting magnification of any area on a computer at 5x to 40x, with a resolution of up to 0.23 micrometers per pixel. Scanning methods include continuous acquisition of microscopic images, seamless stitching, and compression technology, generating digital files that can be stored and transmitted.

[0003] Angle adjustment devices are used in digital slicing scanning. A search revealed a patent document with publication number CN221686183U, which discloses an angle fine-tuning device for digital slicing scanning. This device includes a main body, a clamping mechanism, and an auxiliary mechanism. The clamping mechanism is located at the upper end of the main body, and the auxiliary mechanism is located at the left end of the clamping mechanism. The main body includes a base, a drive motor, and a transmission shaft. The drive motor is fixedly installed in the middle of the inner end of the base. This angle fine-tuning device for digital slicing scanning utilizes the installation of the main body to fix the rotating table with a connecting rod, thereby effectively adjusting the angle of the rotating table. By controlling the speed of the drive motor, it achieves good positioning accuracy and facilitates fine-tuning of the angle. The anti-slip texture A prevents slippage and damage during handling. A control button controls the start of the drive motor, improving the practicality of this angle fine-tuning device for digital slicing scanning.

[0004] However, the clamping mechanism in this utility model clamps the slice by rotating a rotary screw. If multiple slices need to be fixed, multiple rotary screws need to be rotated. This is not only cumbersome to operate and increases the workload of personnel, but also reduces the efficiency of slice scanning. Therefore, an angle fine-tuning device for digital slice scanning is proposed to solve the problems mentioned above. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: an angle fine-tuning device for digital slice scanning, comprising a turntable, a first electric slide fixedly mounted on the top of the turntable, a movable stage fixedly mounted on the output end of the first electric slide, the top of the movable stage being U-shaped, and parallel sliding rods fixedly mounted at the front and rear ends of the movable stage, a U-shaped fixing block slidably mounted on the top of the movable stage and slidably mounted on the outside of the sliding rods, a first spring fixedly mounted between the left side of the fixing block and the left end of the movable stage, and a pull rod extending to the left side of the movable stage fixedly mounted on the left side of the fixing block.

[0007] Furthermore, three sets of clamping mechanisms are arranged in an array on the right side of the fixed block and located on the top of the moving platform. Each clamping mechanism includes a clamping block. A movable groove is opened on the right side of the fixed block. A guide rod extending into the movable groove and slidably installed therein is fixedly installed on the left side of the clamping block. A second spring located outside the guide rod is fixedly installed between the left side of the clamping block and the right side of the fixed block.

[0008] Furthermore, the end of the guide rod located in the movable groove is T-shaped, and the inner dimensions of the movable groove are adapted to the dimensions of the guide rod.

[0009] Furthermore, rubber blocks are provided on the right side of the three clamping blocks and on the right inner arm of the moving platform.

[0010] Furthermore, the turntable is T-shaped, and a cover cylinder is rotatably mounted on the outer side of the bottom end of the turntable. A worm gear is provided on the outer side of the bottom end of the turntable. A servo motor is fixedly mounted on the front side of the cover cylinder. The output end of the servo motor extends into the cover cylinder and a worm gear meshing with the worm gear is fixedly mounted.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1 to 4This embodiment provides an angle fine-tuning device for digital slice scanning, comprising a turntable 1. A first electric slide 2 is fixedly mounted on the top of the turntable 1. A movable stage 3 is fixedly mounted on the output end of the first electric slide 2. Parallel slide rods 4 are fixedly mounted on the front and rear ends of the movable stage 3, respectively. A U-shaped fixing block 5 is slidably mounted on the top of the movable stage 3 and slidably mounted on the outside of the slide rods 4. The top of the movable stage 3 is U-shaped and works with the fixing block 5 to clamp the slice. A first spring 6 is fixedly mounted on the left side of the fixing block 5 and the left end of the movable stage 3, located on the outside of the slide rods 4. A pull rod 7 extending to the left side of the movable stage 3 is fixedly mounted on the left side of the fixing block 5. When clamping the slice, simply pull the pull rod 7 to the left to move the fixing block 5 to the left and place the slice on the top of the movable stage 3. After releasing the pull rod 7, the fixing block 5 clamps the slice under the action of the first spring 6. The clamping method is simple to operate. The first electric slide 2 drives the movable stage 3 to move back and forth on the turntable 1, which can adjust the position of the slice on the top of the turntable 1.

[0019] In this embodiment, three sets of clamping mechanisms 8 are arranged in an array on the right side of the fixed block 5 and located on the top of the moving platform 3. In specific implementation, the number of clamping mechanisms 8 is not limited to three sets depending on the usage. Each clamping mechanism 8 includes a clamping block 81. A movable groove 82 is opened on the right side of the fixed block 5. A guide rod 83 extending into the movable groove 82 and slidably installed therein is fixedly installed on the left side of the clamping block 81. A second spring 84 located outside the guide rod 83 is fixedly installed between the left side of the clamping block 81 and the right side of the fixed block 5. Multiple sets of clamping mechanisms 8 can clamp multiple digital slices at the same time. Due to the arrangement of the clamping block 81, guide rod 83, and second spring 84, digital slices of different sizes can be clamped, improving applicability. The end of the guide rod 83 located in the movable groove 82 is T-shaped, and the inner dimension of the movable groove 82 is adapted to the dimension of the guide rod 83. Rubber blocks are provided on the right side of the three clamping blocks 81 and the inner right arm of the moving platform 3, which makes the clamping more stable and also protects the slices.

[0020] In this embodiment, the turntable 1 is T-shaped, and a cover cylinder 9 is rotatably mounted on the outer side of the bottom end of the turntable 1. A worm gear 10 is provided on the outer side of the bottom end of the turntable 1. A servo motor 11 is fixedly mounted on the front side of the cover cylinder 9.

The rear end of the worm 12 is rotatably mounted on the inner side wall of the cover cylinder 9. The servo motor 11 drives the worm 12 to rotate, causing the meshing worm gear 10 to rotate, which in turn drives the turntable 1 to rotate, thereby achieving fine-tuning of the angle of the slice held at the top of the turntable 1. Due to the high transmission ratio of the worm gear 10 and the worm 12, the rotation angle of the turntable 1 can be more precise.

[0021] Specifically, a number of ball bearings 13 are provided at the contact point between the top of the cover cylinder 9 and the turntable 1. The ball bearings 13 are arranged in a circular array on the top of the cover cylinder 9. The arrangement of the ball bearings 13 can reduce the contact friction between the cover cylinder 9 and the turntable 1, making the turntable 1 rotate more smoothly.

[0022] In this embodiment, a second electric slide 14 is provided at the bottom of the cover cylinder 9. The movable end of the second electric slide 14 is fixedly installed at the bottom of the cover cylinder 9. The second electric slide 14 can drive the cover cylinder 9 and the turntable 1 to move left and right, and can adjust the different positions of the top slice of the turntable 1, thereby improving flexibility.

[0023] The working principle of the above embodiments is as follows: When clamping the slice, pull the lever 7 to the left, which moves the fixing block 5 to the left and places the slice on the top of the moving stage 3. After releasing the lever 7, the fixing block 5 clamps the slice under the action of the first spring 6. The clamping method is simple to operate. Multiple clamping mechanisms 8 can clamp multiple digital slices at the same time. Due to the setting of clamping block 81, guide rod 83 and second spring 84, digital slices of different sizes can be clamped, improving applicability. The setting of the first electric slide 2 and the second electric slide 14 can adjust the overall position of the moving stage 3 and the turntable 1, improving flexibility.
