[0023] In this embodiment, after the two glass slides are cleaned and sterilized, the laser instrument 8 is turned on to form an aperture at the center of the glass slide 402. The laser instrument 8 uses a monochromatic laser light source. The laser beam is adjusted to a specific shape and direction through a lens or other optical elements. By adding a light hole in the light path, the laser instrument 8 can form a uniform circular ring on the glass slide 402. Then the staff can place the biological specimen inside the aperture and then rotate the rotating block 407 upward. When the cover glass 406 is placed flat inside the card slot 10, the top of the rotating block 407 protrudes from the top of the stage 203. The purpose is to facilitate the rotation of the cover glass 406. Through the effect of the damping shaft 404, the cover glass 406 can be slowly rotated during the rotation process until the rotating block 407 rotates to the top of the positioning block 403, that is, the positioning of the biological specimen is completed, and then the forward and reverse motor 507 located at the bottom is started to drive the rotating rod 508 to rotate, thereby driving the eccentric wheel 509 connected thereto to rotate. When the connecting rod 512 rotates to the top, the cylinder 513 is started to extend it, driving the support rod 514 to move upward, thereby moving the slide glass 402 upward, thereby driving the positioning block 403 upward, and at this time, the first An electromagnet 408 is electrically connected to an external power source to generate a magnetic field. When the first electromagnet 408 moves upward to a position corresponding to the two positioning balls 608, the positioning balls 608 are made of metal iron and move toward the direction of the first electromagnet 408 under the action of magnetic force, thereby extending the two springs 607 and driving the two positioning balls 608 to snap onto the opposite outer surfaces of the positioning block 403.

Since the alcohol solution has strong volatility, when the cleaning sleeves 510 are away from the glass slide 402 and the cover glass 406, the alcohol retained on the glass slide can evaporate quickly, and turn on the two ultraviolet lamps 511 at the same time, and sterilize the glass slide 402 and the cover glass 406 again by moving the mobile frame 501, wherein the UV-C light emitted by the ultraviolet lamp 511 can effectively kill bacteria, viruses and other microorganisms on the glass slide 402 and the cover glass 406.

[0028] The use method and working principle of this device: In the field of biotechnology, when it is necessary to conduct microscopic observation of biological specimens, first Figure 1 As shown, the unfolded slide glass 402 and cover glass 406 are stably placed inside the card slot 10, so that the rotating block 407 and the positioning block 403 are respectively embedded in the card slot 10. Figure 2The interior of the card slot 10 shown in the figure, and then start the two forward and reverse motors 507 respectively, drive the two rotating rods 508 to rotate, and then drive the two eccentric wheels 509 to rotate, so that the two cleaning sleeves 510 are respectively rotated to the position where they are in contact with the outer surfaces of the slide glass 402 and the cover glass 406, and then start the driving motor 503, and the rotation of the mounting shaft 504 drives the rotating gear 505 to rotate, so that the rotating gear 505 moves along the tooth row 506, thereby driving the two cleaning sleeves 510 to move along the tooth row 506, and then the two cleaning sleeves 510 move along the slide glass 402 and the cover glass 406, so as to clean both sides of the slide glass 402 and the cover glass 406. When the cleaning is completed, start the two forward and reverse motors 507 again to drive The two cleaning sleeves 510 can be rotated to a position away from the slide glass 402 and the cover glass 406. Since the alcohol solution has strong volatility, when the cleaning sleeve 510 is away from the slide glass 402 and the cover glass 406, the alcohol retained on the slide glass can evaporate quickly, and the two ultraviolet lamps 511 are turned on at the same time, and the slide glass 402 and the cover glass 406 are sterilized again by moving the movable frame 501. When the two slides are cleaned and sterilized, the laser instrument 8 is turned on to form an aperture at the center of the slide glass 402, so that the laser instrument 8 can form a uniform circular ring on the slide glass 402, and then the staff can place the biological specimen inside the aperture, and then rotate the rotating block 407 upward until the rotating block 407 rotates to the positioning block 403. The top of the biological specimen is reached, and the positioning of the biological specimen is completed. Then, the forward and reverse motor 507 located at the bottom is started to drive the rotating rod 508 to rotate, thereby driving the eccentric wheel 509 connected thereto to rotate. When the connecting rod 512 rotates to the top, the cylinder 513 is started to extend, driving the supporting rod 514 to move upward, thereby moving the slide 402 upward, thereby driving the positioning block 403 to move upward. At this time, the first electromagnet 408 is electrically connected to the external power supply to generate a magnetic field. When the first electromagnet 408 moves upward to the position corresponding to the two positioning balls 608, since the positioning balls 608 are made of metal iron, they move in the direction of the first electromagnet 408 under the action of magnetic force, thereby extending the two springs 607 and bringing The two positioning balls 608 are moved to snap onto the opposite outer surfaces of the positioning block 403, thereby fixing and clamping the positioning block 403, and then the stepper motor 602 can be started to drive the screw rod 603 to rotate, thereby driving the clamping block 605 to move along the direction of the screw rod 603. The movement of the clamping block 605 drives the positioning block 403 to move, thereby driving the slide glass 402 and the cover glass 406 to move, thereby driving the biological specimen to move forward. When the clamping block 605 moves to the mounting plate 601 close to the position of the light hole 11, the center position of the slide glass 402 moves to the center position of the light hole 11. At this time, the positioning block 403 moves to the position that coincides with the top of the second electromagnet 907, and the second electromagnet 907 is electrically connected to the external power supply, such as Figure 5 and Figure 6 As shown, there is a thin layer of metal iron material at the bottom of the positioning block 403. When the second electromagnet 907 generates a magnetic field, the positioning block 403 will be adsorbed on the surface of the second electromagnet 907 under the action of the magnetic force, and then the first electromagnet 408 will be disconnected from the external power supply, so that the two positioning balls 608 are respectively reset under the elastic action of the two springs 607 and removed from the inside of the positioning block 403 to release the clamping of the positioning block 403, and then the electric push rod 906 can be started to drive the second electromagnet 907 to move downward, and then the positioning block 403 can be driven to move downward. When the bottom of the first mounting frame 401 contacts the bottom of the stage 203, the positioning and placement of the biological specimen is completed. Then the converter 205 can be rotated to adjust the position of the objective lens 206, so that the low-power objective lens 206 is aligned with the light-through hole 11, and the coarse focusing screw 207 can be turned to make the objective lens 206 close to the specimen. The light intensity of the biological specimen is adjusted through the fill light 204, and then the magnification of the object is adjusted. Then the coarse focusing screw 207 can be turned until a clear biological specimen is seen. When a position is not convenient for observation, the servo motor 903 is started to drive the active gear 904 to rotate, and then the gear ring 902 is driven to rotate, thereby driving the hollow circle 901 to rotate, so that the slide 402 is rotated, and then the biological specimen is driven to rotate at the position of the light-through hole 11, by debugging the hollow circle 901.
