When the lifting plate 701 of the compressing assembly is stressed to rise, the lifting plate 701 drives the pre-pressing plate 702 to rise synchronously, and at the moment, the second resetting piece 704 is in a compressed state; when the force applied to the pressing assembly disappears, the elastic force released by the second resetting piece 704 enables the lifting plate 701 and the prepressing plate 703 to automatically reset, and the prepressing plate 703 descends to the original position and then is pressed on the edges of the two short edges of the slide, so that the stability of the slide is improved, and the interference of the external environment on the slide is reduced.

In other embodiments of the present invention, as shown in fig. 14-16, the pressing assembly further includes a buffer 707 attached to the bottom of the lifting plate 701, where the buffer 707 is located at the mounting port of the mounting platform F, and can buffer the lifting plate 701 when the lifting plate 701 descends, so as to ensure that the lifting plate 701 and the prepressing plate 703 descend stably.

As shown in fig. 12 and 14, the trigger assembly includes a guide member (i.e., a guide block 705) disposed below the connecting block 311 and a rotating member 706 (the rotating member 706 is a flange bearing) disposed on the stage F, the guide block 705 is provided with a guide channel engaged with the rotating member 706, the height of the guide block 705 is slightly higher than that of the rotating member 706, when the guide block 705 passes through the rotating member 706, the rotating member 706 is clamped in the guide channel, so that the lifting plate 701 and the pre-pressing plate 703 are synchronously lifted, so that the slide pushing mechanism can push the slide onto the stage F; when the guide block 705 moves away from the rotating member 706, the lifting plate 701 and the pre-pressing plate 703 automatically reset under the action of the second resetting member, so that the slide is pre-pressed on the stage F, and the stability of the slide is improved.

The working process and principle of the utility model are briefly described as follows:

before the slide glass detection is carried out, the pushing claw 313 is ensured to move to the upper part of the object stage F so as to avoid the pushing claw 313 from obstructing the movement of the slide glass at the lower part to the object stage F, as shown in fig. 1 in particular;

placing the slide at the inlet end of the first conveying belt 204, detecting the slide placing in-place information by the first slide in-place sensor 205 at the lower part, sending an action instruction to the second motor 502 by the control system, and driving the first conveying belt 204 and the second conveying belt 404 to synchronously move by the second motor 502 through the second synchronous belt 506 to realize the equidistant conveying and the sheet withdrawing of the slide;

when the slide moves to the exit end of the first conveyor belt 204, the second slide-in-place sensor 206 transmits the detected slide signal to the control system, and the control system sends a pause instruction to the second motor 502 and a return motion instruction to the first motor 306, so that the pushing claw 313 moves to the right;

when the pushing claw 313 moves back, when the pushing claw 313 passes through the limit plate 603, the pushing claw 313 rotates upward by a certain height due to the resistance of the limit plate 603 so as to smoothly pass through the limit plate 603, and when the pushing claw 313 passes through the limit plate 603, the pushing claw 313 automatically falls under the action of gravity, and when the origin sensor 314 detects the in-place information of the sensing piece 315, it indicates that the pushing claw 313 is located at the origin position, as shown in fig. 17 specifically;

the control system sends a pushing instruction to the first motor 306 (that is, the pushing claw 313 moves leftwards), the first motor 306 drives the pushing claw 313 to move leftwards so as to push the slide at the outlet end of the first conveying belt 204 onto the object stage F, when the pushing claw 313 passes through the position limiting plate 603, because the position limiting plate 603 has a bevel edge, the pushing claw 313 pushes the bevel edge of the position limiting plate 603 to clamp the position limiting plate 603 in the mounting groove, so that the pushing claw 313 can pass through the mounting groove smoothly, and when the pushing claw 313 passes through the rear position limiting plate 603, the pushing claw is automatically reset under the action of the torsion spring 605;

when the pushing claw 313 moves to the outlet end of the first conveying belt 204 leftwards, the pushing claw 313 pushes the slide to move leftwards continuously, when the guide block 705 at the left end of the connecting block 311 moves to the position of the bearing, the bearing is clamped on the guide block 705, and when the guide block 705 moves leftwards continuously, the bearing drives the lifting plate 701 and the pressing blocks to move upwards for a certain height under the action of the guide block 705, so that the slide enters the object stage F successfully, when the guide block 705 moves away, the lifting plate 701 and the pressing blocks automatically descend and reset under the action of the second resetting piece 704, and the two pressing blocks press the two short sides of the slide to provide the stability of the slide;

after the slide pre-pressing is finished, focusing and photographing the slide by using microscope equipment; if the photographing in multiple directions is needed, the pushing claw 313 returns to the right, the guide block 705 enables the bearing to be clamped in the guide block 705 when moving to the position of the bearing in the return process, the lifting plate 701 and the pressing block ascend to move to the height, then the pushing claw 313 pushes the slide to the left, and the pressing block is utilized to pre-press and fix the slide again so as to facilitate focusing and photographing; after the photographing of the slide is completed, the slide withdrawing mechanism 400 and the slide feeding mechanism 200 move synchronously, so that the slide on the stage F moves onto the second conveyor belt 404, and simultaneously the slide pushing mechanism 300 resets to the right to push the next slide.
