[0047] The slide pushing mechanism can reciprocate between the slide feeding mechanism and the slide returning mechanism to realize the relay conveying of the slide, and the pushing claw can push the slide to move left and right on the objective table to realize the photographing detection of the slide at different positions.
[0048] The push claw limiting structure can limit the movement track of the push claw, so that the push claw can smoothly pass when pushing the slide and rotate upward when returning, effectively avoiding the slide from contacting the slide when returning, preventing cross contamination between samples, improving detection accuracy, and ensuring normal transportation of the slide;

[0143] The two pre-pressing members are pre-pressing plates 803, the two pre-pressing plates 803 are arranged at the front and rear ends of the lifting plate 801 respectively, the horizontal section of the pre-pressing plate 803 is located above the object table 235, and the end portion of the pre-pressing plate 803 is provided with a pre-pressing table for fixing the slide;
[0144] The second reset member 804 is a compression spring, and one compression spring is sleeved on each guide shaft 802, so that the lifting plate 801 and the pre-pressing plate 803 are automatically reset and lowered to the original height.

[0147] The specific working process of the present application is as follows:
[0148] Before the slide detection, the pushing claw 413 is moved to the upper side or the left side of the object table 235, so as to avoid the pushing claw 413 hindering the slide below from moving to the object table 235, as shown in Figure 1 .
[0149] The slide is placed at the inlet end of the first conveying belt 304, at which time the second slide-in-place sensor 305 below detects the slide-in-place information, and the control system sends an action instruction to the third motor 602, which drives the first conveying belt 304 and the second conveying belt 504 to move synchronously through the second synchronous belt 606, so as to realize the equal-interval conveying and slide returning of the slide;
[0150] When the slide moves to the outlet end of the first conveying belt 304, the third slide-in-place sensor 306 transmits the detected slide signal to the control system, which sends a pause instruction to the third motor 602 and a return action instruction to the second motor 405, so as to make the push claw 413 move rightward in return;
[0151] When the push claw 413 passes through the limiting plate 703, the push claw 413 is turned upward by a certain height due to the resistance of the limiting plate 703, so as to smoothly pass through the limiting plate 703, and after the push claw 413 passes through the limiting plate 703, it automatically falls under the action of gravity, and when the origin sensor 414 detects the in-place information of the inductive sheet 415, it indicates that the push claw 413 is at the origin position;
[0152] The control system sends a push instruction (i.e. the push claw 413 moves leftward) to the second motor 405, which drives the push claw 413 to move leftward to push the slide at the outlet end of the first conveying belt 304 onto the object table 235, and when the push claw 413 passes through the limiting plate 703, the push claw 413 pushes the inclined edge of the limiting plate 703 to make the limiting plate 703 clamped in the mounting groove, so as to smoothly pass through, and after the push claw 413 passes through, the limiting plate 703 is automatically reset under the action of the torsional spring;
[0153] When the push claw 413 moves leftward to the outlet end of the first conveying belt 304, the push claw 413 pushes the slide to continue moving leftward, when the fourth guide block 806 at the left end of the connecting block 410 moves to the bearing position, the bearing is clamped on the fourth guide block 806, and when the fourth guide block 806 continues to move leftward, the flange bearing drives the lifting plate 801 and the pre-pressing plate 803 to move upward by a certain height under the action of the fourth guide block 806, so that the slide successfully enters the object table 235, and after the fourth guide block 806 drives away, the lifting plate 801 and the pre-pressing plate 803 are automatically lowered and reset under the action of the second reset member 804, and the two pre-pressing plates 803 press the two short edges of the slide, so as to ensure the stability of the slide;
[0154] After the pre-pressing of the slide is completed, the microscope device focuses and takes pictures of the slide: when the first slide-in-place sensor 234 detects the slide-in-place information on the stage 235, the first slide-in-place sensor 234 transmits the detected slide-in-place signal to the control system, and after the control system receives the slide-in-place signal, the control system sends an action instruction to the first motor N, and the first motor N drives the objective lens 210 to the highest point through the gear transmission pair and the cam 218, and then the objective lens 210 is lowered to the HOME position, and in the process of lowering, the read-write head 229 reads the information on the grating ruler 228, and when the information read by the read-write head 229 is consistent with the height corresponding to the HOME position, the objective lens 210 is lowered to the position; then the first motor N drives the objective lens assembly to rise through the gear transmission pair and the cam 218, and the cam follower 219, and the objective lens 210 starts to focus, and in the process of focusing, the camera M takes pictures and transmits the pictures to the control system, and the control system analyzes and judges the pictures to find the clearest picture to determine the clearest focusing surface, and after the camera M takes pictures under the focusing surface and records the video, the control system controls the first motor N to make the objective lens 210 rise and reset to the highest position.
[0155] If it is necessary to take pictures of different positions of the slide, the push pawl 413 returns to the right, the fourth guide block 806 moves to the bearing position in the return stroke, and the bearing is clamped in the fourth guide block 806, the lifting plate 801 and the pre-pressing plate 803 are raised and moved to a height, and then the push pawl 413 pushes the slide to the left, and the pre-pressing plate 803 is used to pre-press and fix the slide, so as to facilitate focusing and photographing; after the slide is photographed, the slide withdrawing mechanism and the slide feeding mechanism 300 move synchronously, so that the slide on the stage 235 moves to the second conveying belt 504, and at the same time, the slide pushing mechanism 400 resets to the right, so as to push the next slide.
