[0038] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present invention and are not intended to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

[0039] Example 1:

[0040] like Figure 1-4 As shown, the first embodiment of the present invention proposes an XY axis moving platform based on a digital slice rapid scanning device, and the moving platform includes:

[0041] The upper plate assembly 1, the middle plate assembly 2 and the lower plate assembly 3 are stacked in sequence from top to bottom;

[0042] A sliding assembly 4 is provided between the upper plate assembly 1, the middle plate assembly 2 and the lower plate assembly 3;

[0043] a driving assembly 5 connected to the upper plate assembly 1 or the middle plate assembly 2 and configured to drive the upper plate assembly 1 or the middle plate assembly 2 to move through the sliding assembly 4, wherein the sliding directions of the upper plate assembly 1 and the middle plate assembly 2 are perpendicular to the horizontal direction;

[0044] A position monitoring component, which is provided between the upper plate assembly 1, the middle plate assembly 2 or the lower plate assembly 3 and is used to monitor the displacement of the upper plate assembly 1 or the middle plate assembly 2;

[0045] The mounting surface of the upper plate assembly 1 is provided with a mounting groove 101 , and a glass slide 7 is mounted in the mounting groove 101 via the switch assembly 6 .

[0046] In the XY-axis motion platform of the digital slide rapid scanning device of the first embodiment, a sliding assembly 4 is provided between the upper plate assembly 1, the middle plate assembly 2, and the lower plate assembly 3 to enable horizontal sliding of the upper plate assembly 1 and the lower plate assembly 3, with the sliding direction being perpendicular to the X-axis and Y-axis directions. Furthermore, a mounting groove 101 is provided on the upper plate assembly 1 for mounting the glass slide 7, achieving an integrated installation of the glass slide 7 mounting platform and the XY-axis motion platform, significantly reducing the device's installation space. Furthermore, a position monitoring assembly is provided between the upper plate assembly 1, the middle plate assembly 2, and the lower plate assembly 3 to monitor the displacement of the upper plate assembly 1 or the middle plate assembly 2, achieving precise, smooth micron-level motion.

[0047] In some preferred embodiments, the switch assembly 6 comprises a pair of slide glass mounting clips 601, symmetrically positioned on either side of the upper plate assembly 1 within the mounting slot 101. One end of each pair of slide glass mounting clips 601 is designed to extend into the mounting slot 101, forming a pressing portion. This portion effectively presses and limits the position of the slide glass 7 mounted within the mounting slot 101, ensuring the stability and safety of the slide glass 7 during operation.

[0048] Furthermore, each slide mounting clamp 601 consists of several key components: a clip, a compression spring, and a stop screw. One end of the clip is secured to the mounting surface of the upper plate assembly 1 via a stop screw, ensuring the clip's structural stability. A compression spring is located between the clip and the mounting surface. This spring provides the necessary elastic support when the clip applies pressure to the slide 7, ensuring that the slide 7 is evenly and stably compressed.

[0049] In addition, the other end of the clip is designed to have a warped edge, which forms the pressing portion of the slide mounting clip 601. The warped edge design extends away from the mounting surface, thus providing a larger contact area when the slide 7 is pressed, increasing the pressing effect while reducing the risk of damage to the slide 7.

[0050] This design not only ensures stable securement of the glass slide 7, but also allows for gentle pressure on the glass slide 7 through the elastic action of the compression spring, preventing unnecessary damage to the glass slide 7 during operation. This design ensures functionality while also balancing ease of operation and protection of the glass slide 7. To adjust the pressure applied to the glass slide 7, adjust the stop screws. First, adjust the position of one end of the clip secured to the mounting surface of the upper plate assembly 1 by the stop screws. Tightening or loosening the stop screws changes the distance between the clip and the mounting surface, indirectly affecting the degree of compression of the compression spring. This changes the spring's elasticity, and thus the pressure applied to the glass slide 7. If the compression spring loses its tension after prolonged use, it should be replaced. If a greater degree of adjustment is required, consider replacing a spring with a different strength. Choosing a harder or softer spring can significantly alter the pressure applied by the clip on the glass slide 7. A stiffer spring will provide more pressure, while a softer spring will provide less pressure.

[0051] In some preferred embodiments, an open entrance is provided on one side wall of the mounting groove 101 for inserting the glass slide 7 .

[0052] In some preferred embodiments, a chamfer 102 is provided at the edge of the entrance of the mounting groove 101 to prevent the slide glass 7 from colliding with the side wall of the mounting groove 101 when the slide glass 7 is inserted.

[0053] In some preferred embodiments, the lower plate assembly 3 is designed with a specially designed mounting hole 201 specifically for mounting a light source. The light source can be installed by directly embedding it in the mounting hole 201 or by securing it with screws, clamps, or other means. Simultaneously, the middle plate assembly 2 is designed with a light-transmitting hole 301 at a position corresponding to the mounting hole 201 of the lower plate assembly 3, ensuring that light emitted by the light source can smoothly penetrate the middle plate assembly 2. A key innovation lies in the precise alignment of the three key components, mounting hole 201, light-transmitting hole 301, and mounting slot 101, in the same vertical direction. This design not only ensures that light from the light source can directly illuminate the glass slide 7 mounted on the upper plate assembly 1, but also ensures stable installation and convenient operation of the glass slide 7. This vertically overlapping design simplifies the structure of the entire assembly, reduces assembly complexity, and improves overall stability and efficiency. This design enables uniform illumination of the glass slide 7, making it suitable for microscopes, projectors, or other equipment requiring precise light illumination. At the same time, due to the precise alignment of the mounting hole 201 , the light-transmitting hole 301 and the mounting groove 101 , it is also convenient to maintain and replace the light source, thereby improving the practicality and flexibility of the device.

[0054] In some preferred embodiments, the position monitoring component includes a magnetic scale, a magnetic scale reading head and a sensor. The magnetic scale is arranged on the upper plate assembly 1, the middle plate assembly 2 and the lower plate assembly 3. The sensor is electrically connected to the magnetic scale reading head. The sensor is used to sense the displacement of the magnetic scale to send the displacement signal to the magnetic scale reading head for reading.

[0055] In this embodiment, the sliding assembly 4 utilizes cross-roller guide technology, which can be installed at appropriate locations on the upper plate assembly 1, the middle plate assembly 2, or the lower plate assembly 3. The cross-roller guide is composed of a series of rollers that roll between the guide rail and the slider to achieve high-precision and high-rigidity linear motion. Through this design, the connection between the components is not only stable and reliable, but also enables smooth and precise relative movement, meeting the strict motion control requirements of precision equipment.

[0056] Example 2:

[0057] The utility model provides a digital slide rapid scanning device, comprising an XY-axis movable platform based on any of the aforementioned digital slide rapid scanning devices. The scanning device utilizes the XY-axis movable platform to provide a mounting slot on the upper plate assembly for mounting a slide, thereby achieving integrated installation of the slide mounting platform and the XY-axis movable platform, significantly reducing the device's installation space.

[0058] It is easy for those skilled in the art to understand that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
