[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0040] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0041] The present embodiment provides a miniature single-slide scanner, comprising a base 2, which defines a first mounting area and a second mounting area. The first mounting area is used to mount a movable platform 1, and the second mounting area is used to mount an imaging mechanism 3. A clamp 6 is provided on the upper surface of the movable platform 1, which is used to clamp a slide. The movable platform 1 is capable of driving the clamp 6 to move along the X-axis and / or the Y-axis. The image acquisition end of the imaging mechanism 3 faces downward and is aligned with the movable platform 1. The movable platform 1 is used to drive the clamp 6 to a position corresponding to the image acquisition end of the imaging mechanism 3.

[0042] In this embodiment, the imaging mechanism 3 includes: a frame 301, which is vertically arranged on the second installation area of ​​the base 2; a horizontal frame is horizontally connected to the top of the frame 301, and the camera module 302 is fixed to the horizontal frame. One end of the optical tube 303 is connected to the camera module 302, and the other end is the image acquisition end; the objective lens 304 is arranged at the other end of the optical tube 303 and is used for imaging and focusing the camera module 302. In the imaging mechanism 3, the imaging module is the core part of the scanner, which is responsible for converting the optical image into an electrical signal, and then into a digital image that can be processed by a computer. The optical tube 303 is used to form the optical path. The imaging module and the optical tube 303 adopt the existing structure, and the imaging principle thereof will not be repeated here.

[0043] This embodiment further includes a voice coil motor 4 mounted on the frame 301. The voice coil motor 4 is primarily composed of a coil, a permanent magnet, an iron core, and a bracket. It is a motor operating on electromagnetic principles and capable of generating linear motion. In this embodiment, a fixed frame 5 is mounted on the output end of the voice coil motor 4. The fixed frame 5 has a mounting portion 501. The optical tube 303 is a hollow tubular structure with a light path formed therein. The mounting portion 501 is mounted on the other end of the optical tube 303. The outer diameter of the mounting portion 501 is substantially the same as the inner diameter of the optical tube 303, allowing for sliding movement between the two. The objective lens 304 is mounted on the mounting portion 501. The voice coil motor 4 is used to drive the fixed frame 5 and the objective lens 304 to move vertically, thereby focusing the image of the camera module 302. When the fixed frame 5 moves vertically, the mounting portion 501 moves up and down within the optical tube 303, but the mounting portion 501 never separates from the other end of the optical tube 303, ensuring the light-tightness of the optical tube 303.

[0044] In this embodiment, a protection spring 8 is provided under the fixing frame 5. The protection spring 8 can be provided between the fixing frame 5 and the frame 301, or between the fixing frame 5 and the base 2. The function of the protection spring 8 is to prevent the objective lens 304 from moving downward excessively, causing the objective lens 304 to collide with the glass slide.

[0045] In this embodiment, the mobile platform 1 includes a slide rail 101 disposed on the base 2 along the Y-axis, a Y-axis platform 103 slidably connected to the slide rail 101, and a receiving chamber is defined below the Y-axis platform 103; a screw motor 104 is disposed on the base 2 and located within the receiving chamber, with the output end of the screw motor 104 connected to the Y-axis platform 103 for driving the Y-axis platform 103 to slide along the Y-axis; an X-axis platform 102 is slidably connected to the upper surface of the Y-axis platform 103 along the X-axis direction, and the sliding structure of the X-axis platform 102 can adopt the same structure as that of the Y-axis platform 103; and a clamp 6 is disposed on the X-axis platform 102. In other embodiments, the X-axis platform 102 and the Y-axis platform 103 can also be replaced with existing dual-axis mobile platforms, as long as they meet the installation requirements of structures such as the condenser 7.

[0046] In this embodiment, the X-axis platform 102 and the Y-axis platform 103 are provided with a focusing hole 105 corresponding to the fixture 6, and a focusing mirror 7 is provided on the base 2. The focusing mirror 7 is located in the accommodating cavity, and its output end faces the focusing hole 105.

[0047] In this embodiment, the clamp 6 includes: a glass slide fixing plate 601, which is fixedly set on the X-axis platform 102, and the glass slide fixing plate 601 defines a clamping area with an open end, and a glass slide can be placed in the clamping area and contact with the glass slide fixing plate 601; a glass slide fixing clamp 602, which is rotatably set on the X-axis platform 102 via a rotating shaft; a torsion spring, one end of the torsion spring is connected to the glass slide fixing clamp 602 and / or the rotating shaft, and the other end is embedded in the X-axis platform 102, and the torsion spring has an elastic tendency to rotate the glass slide fixing clamp 602 toward the clamping area. The glass slide fixing plate 601 and the glass slide fixing clamp 602 can fix the glass slide in the clamping area.

[0048] The specific working process is as follows:

[0049] Manually overcome the elastic force of the torsion spring, push open the glass slide fixing clamp 602, place the glass slide in the clamping area, slowly release the glass slide fixing clamp 602, and the glass slide fixing clamp 602 automatically clamps the glass slide under the action of the torsion force of the torsion spring. The glass slide is fixed in the clamping area by the glass slide fixing plate 601 and the glass slide fixing clamp 602.

[0050] The slide is moved to the position directly below the objective lens 304 by moving the platform 1 .

[0051] The height of the objective lens 304 is adjusted by the voice coil motor 4 so that the camera module 302 can focus its imaging.

[0052] By moving the platform 1 to perform linear rotational motion (X-axis and Y-axis compound motion) along the length of the slide, the camera module 302, optical tube 303 and objective lens 304 are used to scan various areas of the specimen on the slide, thereby completing a comprehensive scan of the specimen.
