[0107] Platform connection block 271 is installed on the active end of Y-axis active component 262;

[0108] Support plate 272 is installed on the top surface of platform connecting block 271;

[0109] A carrying plate 273 is mounted on a support plate 272. A hook 2731 is formed on the end face of the carrying plate 273. A barb is formed on the end of the hook 2731 away from the support plate 272 to prevent the slide 221 from sliding off. Reserved spaces are formed on both sides of multiple shelves 2221 in the slide box body 222 so that the hook 2731 on the carrying plate 273 can extend into the slide box body 222 and extract the slide 221 on the shelf 2221.

[0110] Several pressure blocks 274 are elastically connected to the support plate 272 by compression springs 275 mounted on the support plate 272; preferably, there are two pressure blocks 274, but of course, the number of pressure blocks 274 is not limited to two, and can also be one, three or more.

[0111] A baffle 276 is fixedly mounted on the imaging support 24. The baffle 276 has a limiting hole 2761 for the slide 221 within the carrier plate 273 and the hook 2731 to pass through. The limiting hole 2761 is used to limit the movement of several pressure blocks 274, thereby enabling the automatic slide clamping assembly 27 to automatically clamp the slide 221. See [details of baffle 276 and limiting hole 2761]. Figure 2 As shown.

[0112] In some embodiments, the platform connecting block 271 is detachably mounted on the movable end of the Y-axis movable assembly 262; the support plate 272 is detachably mounted on the top surface of the platform connecting block 271. This detachable mounting method facilitates disassembly and assembly by maintenance personnel, improving efficiency.

[0113] In some embodiments, the digital slice scanning device further includes a control system, which is electrically connected to the transport assembly 21, the sample loading assembly 23, the slice imaging module 25, and the multi-axis moving platform 26. Adding a control system improves the intelligence level of the digital slice scanning device and reduces the workload of operators.

[0114] The working principle of the digital slice scanning device is as follows:

[0115] First, the conveying component 21 conveys the slide box 22 to the side of the sample loading component 23 until the slide box protrusion 224 on the back of the slide box body 222 abuts against the sample loading stop 233 on the sample loading component 23. At this moment, the slide box 22 is blocked by the sample loading stop 233 and is in a stationary state. Then, the sample loading drive on the sample loading component 23 is activated. The sample loading drive drives the insert plate 234 to move upward. The bayonet on the insert plate 234 extends into the slot 2231 of the fixing block 223, and the slide box 22 is gradually lifted upward through the insert plate 234 until the bottom surface of the pressure plate 235 contacts the top surface of the slide box 22, and the slide box 22 is pressed downward. At this moment, the slide box 22 is in a stationary state. Then, the multi-axis moving platform 26 is activated, and the automatic slide clamping component 27... The slide plate 273 extends into the slide box 22 through the limiting hole 2761 of the baffle 276 via the multi-axis moving platform 26. At this moment, the pressure block 274 on the automatic slide clamping assembly 27 is blocked by the limiting hole 2761, and the hook 2731 on the slide plate 273 is in the fully open state. The sample loading drive drives the slide box 22 to move downward a small step, and the slide 221 on the slide box 22 falls into the hook 2731 of the slide plate 273. Then, the slide plate 273 is pulled out from the slide box 22 by the X-axis moving assembly 261. Under the action of the compression spring 275, the slide 221 on the slide plate 273 is clamped by the pressure block 274 and moved to the observation area between the light source 251 and the objective lens 253 by the multi-axis moving platform 26.

[0116] Light from light source 251 passes through slide 221 and enters objective lens 253, then enters imaging lens mounted on imaging tube 254, ultimately imaging the slice on slide 221 onto camera 255. Objective lens 253 is mounted on Z-axis moving platform 256 and can move up and down to achieve focusing. Slide 221 on slide plate 273 moves horizontally along the X-axis and Y-axis directions with X-axis moving component 261 and Y-axis moving component 262 respectively, thus completing the scanning function.

[0117] The automatic slide clamping assembly 27 of this invention does not completely detach from the slide holder 221 during the process of clamping the slide 221, reducing the risk of slide 221 fragmentation caused by the large degree of freedom and detachment from the slide holder 221 in traditional clamping mechanisms. Furthermore, the clamping process of the automatic slide clamping assembly 27 is safer, more stable, and more reliable.

[0118] In addition, the automatic slide clamping assembly 27 in this utility model realizes the automatic clamping function of the slide 221 by adding a pressure block 274, a pressure spring 275 and a baffle 276. The clamping action only has three steps: First, the X-axis moving assembly 261 drives the carrier plate 273 to extend into the slide box 22; Second, the sample loading drive drives the slide box 22 to move downward a small step, so that the slide 221 falls into the hook 2731 of the carrier plate 273. Third, the X-axis movable component 261 is driven to move in the opposite direction, so that the carrier plate 273 extends out from the limiting hole 2761 opened in the baffle 276, so that the glass slide 221 on the carrier plate 273 is clamped by the pressure block 274 under the action of the compression spring 275, thereby completing the automatic clamping function of the glass slide 221. Compared with the traditional robotic arm clamping of the glass slide 221, the automatic glass slide clamping component 27 provided by this utility model has fewer actions and saves the time of loading the slide.
