The working principle of the invention is as follows:
firstly, the pushing plate 508 is pulled rightwards, the slide 22 to be scanned is placed on a slide installation acupoint of the slide frame 5, the slide 22 is limited in the Y direction through a limiting pin 506 on the front edge or the rear edge of the slide installation acupoint, then the pushing plate 508 is loosened, the pushing plate 508 automatically resets leftwards along a needle gauge 509 under the action of a spring, a tail inclined block 507 at the left end of the slide installation acupoint and the reset pushing plate 508 clamp the slide 22, the positioning in the X direction is realized, and therefore the slide 22 is effectively fixed on the slide frame 5;
then, the slide holder 5 with the slide 22 fixed thereon is inserted into the double arm support 102 at the front end of the slide holder stage integrated unit 1, at this time, the left edge of the slide holder 5 is supported on the support plate 10 of the left front arm of the double arm support 102, the right part of the slide holder 5 is supported on the electromagnet base 6 on the right front arm of the double arm support 102, and the small magnet block 8 on the upper surface of the electromagnet base 6 and the neodymium magnet block 9 on the side surface of the electromagnet base 6 initially position the slide holder 5 from the Z direction and the X direction, respectively;
since the flatness of the contact portion of the slide holder 5 and the electromagnet base 6 is 5 μm, it is necessary to horizontally adjust the electromagnet base 6 before scanning the slide in order to ensure the levelness of the slide holder 5 at the time of scanning; in the front-back direction, jackscrews are installed by utilizing two threaded holes in the top of the electromagnet seat 6, so that horizontal adjustment in the front-back direction is realized; in the left and right direction, the horizontal adjustment in the left and right direction is realized by using the padding height of metal gaskets (0.001-0.1mm) with different thicknesses.
When scanning is started, the electromagnet coil 7 on the upper surface of the electromagnet seat 6 is electrified to generate large magnetic force and firmly suck the right part of the slide rack 5, so that the slide rack 5 is completely fixed in the double-arm support 102 at the front end of the slide rack and slide carrier integrated piece 1, the slide rack 5 and the slide rack and slide carrier integrated piece 1 form a whole during scanning, the planar stability of a slide 22 during scanning is ensured, and the scanning quality is improved;
after the slide is swept, the electromagnet coil 7 is powered off, the large magnetic force disappears, the slide frame 5 can be smoothly drawn out from the double-arm support 102 at the front end of the slide frame and slide piece 1, then the pushing plate 508 is pulled off rightwards again, the slide 22 needing to be scanned is taken down from the slide installation acupuncture point of the slide frame 5, finally the pushing plate 508 is loosened again, the pushing plate 508 automatically resets leftwards along the needle gauge 509 under the acting force of the spring, and the next batch of slides 22 are waited to be changed, so that the slide 22 is conveniently replaced, and the slide frame 5 is convenient to insert and pull out.
In the scanning process, a displacement sensor consisting of an X grating ruler 11, an X grating ruler fixed plate 12, an X grating ruler reading head 13, an X grating ruler reading head support 14 and an X grating ruler reading head fixing seat 15 can detect the displacement distance of the integrated slide frame carrier 1 in the X direction in real time, the X grating ruler 11 is fixed on the lower surface of the integrated slide frame carrier 1 through the X grating ruler fixed plate 12, the X grating ruler reading head 13 is fixed on the X-axis bottom plate 4 through the X grating ruler reading head support 14 and the X grating ruler reading head fixing seat 15, when the slide frame and slide carrier integrated piece 1 slides on the X-axis bottom plate 4 through the X-axis slide rail assembly 2, the X-ray grating ruler 11 moves along with the slide frame and slide carrier integrated piece 1, the X grating scale reading head 13 is kept still relative to the X grating scale 11, and the X grating scale reading head 13 reads the scales on the X grating scale 11, so that the displacement distance of the integrated piece 1 of the slide frame bearing table in the X direction is detected in real time; and because the push block 3 and the slide frame and slide holder integrated piece 1 are connected by three parallel X-axis linear guide rails 19 in a locking manner, the function of buffering and damping is achieved, and the vibration isolation of the thrust of the motor is realized, so that the sliding stability of the slide frame and slide holder integrated piece 1 is improved, the stability of the X grating ruler reading head 13 during detection is also improved, in addition, the detection precision of the X grating ruler reading head 13 can reach 0.1 mu m, and the precision is relatively high.
