The transport mechanism 31 is capable of transporting the slide rack 22 to the scanning platform. The slide basket 26 is adapted to receive a greater number of slide racks 22.

In some embodiments, as shown in FIGS. 2 and 4 in combination, the slide racks 22 are used to carry slides, and the slide racks 22 are mounted in a slide basket 26. Specifically, by placing slides on the slide rack 22, contamination of the specimen by direct operator contact with the slides is avoided, and multiple slides can be placed on the slide rack 22, enabling the microscope assembly to detect multiple specimens. A plurality of slide racks 22 can be mounted within the slide basket 26 for carrying and transporting the plurality of slide racks 22.

Specifically in this embodiment, the slide rack 22 includes a body 23 and a clamping assembly 24. The main body 23 includes a surrounding edge 231 and a supporting portion 232 connected to the surrounding edge 231. The support 232 is used to support the slide, and the clamping assembly 24 is disposed on the perimeter 231. The clamping assembly 24 includes a first clamping structure 24a and a second clamping structure 24b, wherein a pick-and-place operation position 233 is formed on the surrounding edge 231, the pick-and-place operation position 233 and the first clamping structure 24a are disposed on two sides of the supporting portion 232, the second clamping structure 24b and the pick-and-place operation position 233 are disposed on the same side of the supporting portion 232, and the second clamping structure 24b is disposed on two sides of the pick-and-place operation position 233.

The taking and placing operation position 233 is arranged between the two second clamping structures 24b, and the taking and placing operation position 233 is opposite to the first clamping structure 24a, so that the two second clamping structures 24b and the first clamping structure 24a are distributed in a triangular mode, stable clamping of the slide can be achieved, meanwhile, the taking and placing operation position 233 between the two second clamping structures 24b can provide a large operation space for an operator, the slide can be taken and placed on the supporting portion 232, and convenience degree of the slide taking and placing operation is improved.

Further, the pick-and-place operation site 233 extends in a direction toward the first clamping structure 24a and beyond the second clamping structure 24b, so that after the slide is placed on the supporting portion 232, a partial area of the slide corresponds to the pick-and-place operation site 233, so that an operator can have a larger contact area with the slide, thereby ensuring stable contact when picking and placing the slide, providing a more stable clamping force, and preventing the slide from falling off. Specifically, the pick-and-place operation site 233 is a groove-shaped structure extending from the peripheral edge 231 to the supporting portion 232 so that the tip of a human finger can be accommodated therein.

Specifically, the slide has a specimen area carrying a biological sample and a bar code area having a bar code for numbering and identifying the corresponding sample. The supporting portion 232 is formed with a hollow area 234 corresponding to the specimen area, and the light can be irradiated to the specimen area through the hollow area 234.

The elastic member 242 elastically acts on the pressing block 241 to provide a clamping force for the pressing block 241 to clamp the slide. The spacing between the compression block 241 and the second clamp structure 24b is increased by moving the compression block 241 away from the pick and place station 233 to facilitate placing a slide therebetween or removing a slide therefrom. When the external force is removed, the elastic member 242 can apply an elastic force to the pressing block 241 to force the pressing block 241 to be close to the pick-and-place operation position 233, so that the pressing block 241 and the second clamping structure 24b clamp the slide together.

In some embodiments, the two opposite sides of the pressing block 241 are provided with the sliders 243, the surrounding edge 231 is provided with a sliding groove 239 extending in the direction toward the pick-and-place operation position 233, and the two sliders 243 are matched with the sliding groove 239 to slide along the sliding groove 239, so that the pressing block 241 slides.

The limiting groove 235 is a strip-shaped groove, when the pressing block 241 slides relative to the surrounding edge 231, the limiting member 244 moves in the limiting groove 235, and two ends of the limiting groove 235 can abut against the limiting member 244 to form two sliding limiting positions of the pressing block 241. Specifically, the retaining member 244 is a pin that is threadedly coupled to the compression block 241. In some embodiments, the surrounding edge 231 is connected with a guiding element 236, the pressing block 241 is provided with a guiding slot 245 extending along the direction toward the pick-and-place operation position 233, and the guiding element 236 cooperates with the guiding slot 245 to guide the pressing block 241. In addition, the guide slot 245 is a blind slot, the guide member 236 is a guide pin screwed to the peripheral edge 231, and the guide member 236 can abut against the bottom wall of the guide slot 245 to form a limit of the moving stroke of the pressing block 241, so that the stroke of the pressing block 241 can be shortened, and the pressing block 241 can move in a small stroke range to clamp and loosen the slide. It should be noted that, in other embodiments, the positions of the sliding slot 239 and the sliding block 243, the positions of the limiting member 244 and the limiting groove 235, and the positions of the guiding member 236 and the guiding groove 245 may be interchanged.

The elastic member 242 abuts against the pressing block 241 to provide an elastic force for the pressing block 241 to clamp the slide. By rotating the adjusting member 247, the position of the adjusting member 247 relative to the second receiving cavity 237 is changed, so as to change the degree of the elastic member 242 compressed by the adjusting member 247, thereby achieving the purpose of adjusting the elastic force of the elastic member 242.

Specifically, the second clamping structure 24b is a protruding block fixedly disposed on the surrounding edge 231 and higher than the supporting portion 232, so that the structure of the second clamping structure 24b is simple and can be abutted against the end surface of the slide along the longitudinal direction to serve as a reference position when the slide is placed on the supporting portion 232.
