Each push plate 508 is provided with an anti-slip stripe 510 for increasing friction, thereby ensuring the fixing effect of the glass slide 22 on the glass slide rack 5.

[0038] For further information, see Figure 5 As shown, the upper surface of the electromagnet seat 6 is evenly embedded with three electromagnet coils 7 along the Y-axis direction, the upper surface of the electromagnet seat 6 is embedded with two small magnet blocks 8, and the two small magnet blocks 8 are respectively located between two adjacent electromagnet coils 7, and the side surface of the electromagnet seat 6 is evenly embedded with three neodymium magnet blocks 9 along the Y-axis direction, thereby ensuring the fixing effect of the glass slide rack 5 on the glass slide rack carrier integrated part 1.

[0039] Furthermore, the number of the electromagnet coils 7 can be designed to be redundant, that is, when one of the electromagnet coils 7 fails, the remaining two electromagnet coils 7 that are working normally can still firmly hold the slide rack 5 .

[0040] For further information, see Figure 1 As shown, an electromagnet wire slot plate 21 is provided on the right side surface of the slide rack stage integrated part 1, so as to cover the lead wire of the electromagnet coil 7 led out from the slide rack stage integrated part 1, thereby beautifying the appearance of the equipment.

[0041] The working principle of the present invention is as follows:

[0042] First, push the push plate 508 to the right, put the glass slide 22 to be scanned into the glass slide mounting hole of the glass slide rack 5, and the glass slide 22 is limited in the Y direction by the limiting pin 506 on the front edge or the rear edge of the glass slide mounting hole. Then release the push plate 508, and the push plate 508 automatically resets to the left along the needle gauge 509 under the action of the spring. The tail inclined block 507 at the left end of the glass slide mounting hole and the reset push plate 508 clamp the glass slide 22 to achieve positioning in the X direction, thereby effectively fixing the glass slide 22 on the glass slide rack 5;

[0043] Then, the slide rack 5 with the glass slide 22 fixed thereon is inserted into the double-arm bracket 102 at the front end of the slide rack stage integrated part 1. At this time, the left edge of the slide rack 5 is supported on the support plate 10 of the left forearm of the double-arm bracket 102, and the right part of the slide rack 5 is supported on the electromagnet seat 6 on the right forearm of the double-arm bracket 102. The small magnet block 8 on the upper surface of the electromagnet seat 6 and the neodymium magnet block 9 on the side surface of the electromagnet seat 6 are used to initially position the slide rack 5 from the Z direction and the X direction respectively.

[0044] Since the flatness of the contact part between the glass slide rack 5 and the electromagnet seat 6 is 5μm, in order to ensure the horizontality of the glass slide rack 5 when scanning the slide, the electromagnet seat 6 needs to be horizontally adjusted before scanning begins; in the front and back directions, the two threaded holes on the top of the electromagnet seat 6 are used to install the top screws to achieve horizontal adjustment in the front and back directions; in the left and right directions, metal gaskets of varying thicknesses (0.001-0.1mm) are used to raise the height to achieve horizontal adjustment in the left and right directions.

[0045] When scanning begins, the electromagnet coil 7 on the upper surface of the electromagnet seat 6 is energized to generate a strong magnetic force and firmly absorb the right part of the slide rack 5, so that the slide rack 5 is completely fixed in the double-arm bracket 102 at the front end of the slide rack stage integrated part 1, so that the slide rack 5 and the slide rack stage integrated part 1 form a whole when scanning, ensuring the stability of the plane of the slide 22 during scanning and improving the scanning quality;

[0046] After scanning is completed, the electromagnet coil 7 is powered off, the strong magnetic force disappears, and the slide rack 5 can be smoothly pulled out from the double-arm bracket 102 at the front end of the slide rack platform integrated part 1, and then the push plate 508 is pushed to the right again, and the slide 22 to be scanned is removed from the slide mounting point of the slide rack 5, and finally the push plate 508 is released again. Under the action of the spring, the push plate 508 automatically resets to the left along the needle gauge 509, waiting for the next batch of slides 22 to be replaced, which is convenient for the replacement of the slides 22 and the insertion and removal of the slide rack 5.

[0047] During the scanning process, the displacement sensor composed of the X-ray scale 11, the X-ray scale fixing plate 12, the X-ray scale reading head 13, the X-ray scale reading head bracket 14 and the X-ray scale reading head fixing seat 15 will detect the displacement distance of the slide holder stage integrated part 1 in the X direction in real time. The X-ray scale 11 is fixed to the lower surface of the slide holder stage integrated part 1 through the X-ray scale fixing plate 12, and the X-ray scale reading head 13 is fixed to the X-axis bottom plate 4 through the X-ray scale reading head bracket 14 and the X-ray scale reading head fixing seat 15. When the slide holder stage integrated part 1 slides on the X-axis bottom plate 4 through the X-axis slide rail assembly 2, the X-ray scale 11 moves along with the slide holder stage integrated part 1. The push block 3 and the slide holder platform integral part 1 are locked and connected through three parallel X-axis linear guide rails 19, which play a role of buffering and shock absorption, and realize the vibration isolation of the motor thrust. Therefore, not only the sliding stability of the slide holder platform integral part 1 is improved, but also the stability of the X-ray scale reading head 13 during detection is improved. In addition, the detection accuracy of the X-ray scale reading head 13 can reach 0.1μm, and the accuracy is relatively high.

[0048] During the scanning process, the limit device composed of two X-axis limit baffles 16, two X-axis optical coupling limit switches 17 and an X-axis optical coupling limit switch fixing plate 18 can limit the displacement distance of the slide rack stage integrated part 1 in the X direction. When the slide rack stage integrated part 1 moves to the left limit position of the X-axis slide rail assembly 2, the X-axis limit baffle 16 on the left triggers the X-axis optical coupling limit switch 17 on the left, thereby stopping the motor from driving the slide rack stage integrated part 1 to work to the left; and when the slide rack stage integrated part 1 moves to the right limit position of the X-axis slide rail assembly 2, the X-axis limit baffle 16 on the right triggers the X-axis optical coupling limit switch 17 on the right, thereby stopping the motor from driving the slide rack stage integrated part 1 to work to the right.

[0049] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
