Description

Technical Field

[0001] This invention relates to the field of slide inspection, and in particular to an automatic slide conveying device for use in the slide inspection process. Background Technology

[0002] A microscope is a commonly used in vitro diagnostic instrument used to magnify and observe cells, bacteria, and hyphae in bodily fluids (such as vaginal discharge, blood, urine, and sputum) to provide a basis for clinical diagnosis. Traditional microscopic examination requires manual slide reading, i.e., manual operation of the microscope for image analysis and interpretation. However, each sample slide requires multiple focusing and photographic comparisons, which is cumbersome and time-consuming. When processing multiple different slides, confusion can easily occur, leading to cross-contamination between samples and affecting the accuracy of clinical diagnostic results.

[0003] Currently, fully automated microscopes have emerged on the market. These microscopes employ distributed control technology and modular embedded structures to automatically adjust the stage in the XYZ directions and regulate the brightness of the light source. Software-based functions include panoramic automatic scanning, automatic image stitching, and automatic slide return. While existing fully automated microscopes achieve automatic focusing and automatic imaging, improving slide reading efficiency to some extent, they still require manual slide placement and cannot achieve automated slide transport. Therefore, designing an automated slide transport device is crucial for achieving automated slide inspection. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic slide conveying device for the slide inspection process. This device not only realizes the automatic conveying of the slides to be inspected, but also conveys the inspected slides to a designated location, laying the foundation for the fully automated inspection of slides.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: The automatic slide conveying device for slide inspection process of the present invention includes a shock-absorbing mounting structure. A slide feeding mechanism, a slide pushing mechanism, and a slide retraction mechanism are sequentially connected on the shock-absorbing mounting structure. The slide pushing mechanism sequentially pushes the slides on the slide feeding mechanism to the stage. After the slide is inspected, the slide pushing mechanism pushes the slides on the stage to the slide retraction mechanism.

[0006] In one embodiment of the present invention, the slide conveying device further includes a limiting structure mounted above the slide feeding mechanism, the limiting structure causing at least one pushing claw of the slide pushing mechanism to return to a vertical state.

[0007] In one embodiment of the present invention, the slide pushing mechanism includes an installation unit vertically disposed on the shock-absorbing installation structure; a first power source disposed on the installation unit; a pushing component being drivenly connected to the first power source; and a guide unit horizontally disposed on the installation unit.

[0008] In one embodiment of the present invention, the push component includes The connection unit is connected to the first power source via a transmission. A sliding unit is horizontally disposed above the connecting unit, and the bottom of the sliding unit is engaged with the guide unit to allow it to move back and forth along the guide unit; and The pushing unit has a fixing member and a pair of pushing claws. The fixing member is fixed to the sliding unit. The fixing member has a pair of symmetrically arranged mounting holes. A pushing claw is hinged in each mounting hole. The lower part of the pushing claw extends downward out of the mounting hole.

[0009] In one embodiment of the present invention, one end of the mounting unit is provided with an origin sensor for detecting the original position of the pusher claw, and the connecting unit is provided with a sensor for triggering the origin sensor.

[0010] In one embodiment of the present invention, the limiting structure includes a limiting seat mounted above the exit end of the slide feeding mechanism, the limiting seat having a guide groove that cooperates with the pusher claw, and each guide groove having a rotatable limiting component to prevent the pusher claw from touching the slide below during the return trip.

[0011] In one embodiment of the present invention, the limiting component includes two limiting units with identical structures, each corresponding to a guide groove. Each limiting unit includes a limiting member rotatably disposed on the limiting seat and a first resetting member for resetting the limiting member. The left end of the limiting member is located within the guide groove.

[0012] In one embodiment of the present invention, the automatic slide conveying device further includes a pre-compression structure for fixing the slide to be inspected on the stage.

[0013] In one embodiment of the present invention, the pre-compression structure includes a clamping component disposed on the stage and a triggering component for triggering the clamping component to rise and fall. The triggering component includes a guide member disposed on the slide pushing mechanism and a rotating member disposed on the stage. The guide member has a guide channel that cooperates with the rotating member.

[0014] In one embodiment of the invention, the clamping assembly includes The lifting component is horizontally installed inside the platform, and the front and rear ends of the lifting component extend outward from the mounting opening of the platform. The guide unit has multiple guide members fixed to the lifting member, the upper part of each guide member extending upward through the platform, and the guide member slidingly engaging with the platform. The pre-compression unit has pre-compression members symmetrically arranged at the front and rear ends of the lifting member, each of the pre-compression members having a pre-compression platform located above the loading platform; and The reset unit automatically resets the lifting and pre-pressing components to their original height.

[0015] In one embodiment of the present invention, the slide feeding mechanism includes The first frame has a pair of legs disposed on the shock-absorbing mounting structure and a mounting member horizontally disposed on the upper part of each of the legs; A first conveying mechanism, disposed between the two mounting components, moves the glass slide toward the stage; and The first support assembly, disposed between the two mounting components, is used to support the glass slide.

[0016] In one embodiment of the present invention, a first glass slide positioning sensor is provided on the first frame corresponding to the inlet end of the first conveying mechanism, and a second glass slide positioning sensor is provided on the first frame corresponding to the outlet end of the first conveying mechanism.

[0017] In one embodiment of the present invention, the ejection mechanism includes The second frame is fixedly connected to the vibration damping mounting structure at the bottom; The second conveying mechanism is located on the upper part of the second frame. The second conveying mechanism and the first conveying mechanism are arranged at left and right intervals, and the conveying directions of the second conveying mechanism and the first conveying mechanism are the same. The second support assembly, located on the upper part of the second frame, is used to support the glass slides.

[0018] In one embodiment of the present invention, the automatic slide conveying device further includes a second power source that drives the first conveying mechanism and the second conveying mechanism to move synchronously. The second power source includes a second driving pulley driven by a second motor, a second driven pulley disposed on the first conveying mechanism, and a third driven pulley disposed on the second conveying mechanism. A transmission belt is sleeved on the second driving pulley, the second driven pulley, and the third driven pulley.

[0019] The advantage of this invention is that it utilizes a slide feeding mechanism, a slide pushing mechanism, and a slide retraction mechanism to achieve automatic slide feeding and retraction, reducing manual intervention and laying the foundation for automated slide inspection.

[0020] The second power source of the present invention can simultaneously drive the synchronous movement of the slide feeding mechanism and the slide retraction mechanism, thereby effectively ensuring the equal spacing of the slides and laying the foundation for the orderly detection of multiple slides.

[0021] The slide pushing mechanism of the present invention can move back and forth between the slide feeding mechanism and the slide ejection mechanism, thereby realizing the relay transport of the slide. The pushing claw can push the slide to move back and forth on the stage, so as to realize the photographic detection of the slide at different positions.

[0022] The limiting mechanism of the present invention can limit the movement trajectory of the pusher claw, so that the pusher claw can pass smoothly when pushing the glass slide and rotate upward on the return trip, effectively avoiding contact between the glass slides on the return trip, preventing cross-contamination between samples, improving detection accuracy, and ensuring normal transportation of the glass slides.

[0040] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. These embodiments are implemented based on the technical solution of the present invention, and detailed implementation methods and specific operation processes are given. However, the scope of protection of the present invention is not limited to the following embodiments.

[0041] like Figure 1 As shown, the automatic slide conveying device for slide inspection process of the present invention includes a shock-absorbing mounting structure 100. A slide feeding mechanism 200, a slide pushing mechanism 300, and a slide retraction mechanism 400 are sequentially connected on the shock-absorbing mounting structure 100. The slide feeding mechanism 200 and the slide retraction mechanism 400 are arranged on both sides of the stage F. The slide pushing mechanism 300 can move back and forth between the output end of the slide feeding mechanism 200 and the input end of the slide retraction mechanism 400, realizing the relay transmission of slides.

[0042] like Figure 2 As shown, the vibration damping mounting structure 100 includes a base plate 101 and vibration damping members 102 spaced apart on the base plate 101. The vibration damping members 102 are preferably rubber vibration damping seats, and each rubber vibration damping seat has a threaded hole for easy installation.

[0043] like Figure 3-5 As shown, the slide feeding mechanism 200 is located on the right side of the stage F, and includes a first frame, a first conveying mechanism and a first support assembly disposed on the first frame; The first frame includes a pair of legs 201 symmetrically arranged on the base plate 101 and a mounting member (the mounting member is a first mounting plate 202 extending in the left-right direction) disposed on the upper part of each leg 201. The first support assembly includes a first support plate 203 fixed between two first mounting plates 202. The first support plate 203 has first positioning grooves extending in the left and right direction at its front and rear edges to facilitate the installation of the first conveyor belt 204 (described later). The height of the first support plate 203 is lower than the height of the upper surface of the first mounting plate 202. The inner side of the first mounting plate 202 can limit the glass slide to ensure that the glass slide runs smoothly. The first conveying mechanism includes a first drive shaft rotatably disposed at the left end of the two first mounting plates 202 and a first driven shaft rotatably disposed at the right end of the two first mounting plates 202. The first drive shaft is provided with two first pulleys that correspond one-to-one with the first positioning grooves, and the first driven shaft is provided with two second pulleys that correspond one-to-one with the first positioning grooves, and each pair of left and right corresponding first pulleys and second pulleys is wound with a first conveyor belt 204 for conveying glass slides. The height of the upper surface of the first conveyor belt 204 is the same as the height of the upper surface of the first support plate 203 to achieve stable operation of the glass slides.

[0044] like Figure 3 , 5 As shown, a first slide positioning sensor 205 is mounted on the right end of the first mounting plate 202 via a fixing bracket. When the first slide positioning sensor 205 detects a slide positioning signal, the second power source 500 (described later) is activated to cause the first conveyor belt 204 to move the slide to the left (i.e., towards the stage). A second slide positioning sensor 206 is mounted on the left end of the first mounting plate 202 via a fixing bracket. When the second slide positioning sensor 206 detects that the slide is in position, it indicates that the slide has been conveyed to the outlet end of the first conveying mechanism. The pusher claw 313 is controlled to return to its original position to bypass the slide, so that the pusher claw 313 is located behind the slide, so as to push the slide to the left. The first slide positioning sensor 205 and the second slide positioning sensor 206 are non-contact sensors, both located below the first support plate 203. To enable them to detect the slides, detection holes 207 are provided at both ends of the first support plate 203 for easy reading of the slides.

[0045] In other embodiments of the present invention: such as Figure 3-4 As shown, the slide feeding mechanism 200 also includes a first tensioning structure, which includes a first mounting block 208 and a second mounting block 209 spaced apart at the left end of each first mounting plate 202. The two first mounting blocks 208 are symmetrically arranged front and rear. The two ends of the first driven shaft are respectively fixed to the first mounting blocks 208 by screws. Each first mounting block 208 has two strip holes 210 extending in the left and right direction. A first limiting screw 211 fixed to the first mounting plate 202 passes through each strip hole 210. The first limiting screw 211 and the strip hole 210 cooperate with each other to guide and limit the first mounting block 208. To ensure that the first driven shaft can move left and right to achieve real-time tensioning of the first conveyor belt 204, the right ends of the two first mounting plates 202 are provided with first guide limiting grooves 212 arranged in the left and right direction, and the two ends of the second driven shaft are fitted into the two first guide limiting grooves 212. Two second mounting blocks 209 are set in a corresponding manner, and a first tension spring 213 (a compression spring) is set between each second mounting block 209 and its corresponding first mounting block 208 to realize the real-time tension of the first conveyor belt 204 and ensure the stability of glass slide transportation.

[0046] like Figure 6 As shown, the ejection mechanism 400 is located on the left side of the stage F, including a second frame mounted on the substrate 101, a second conveying mechanism and a second support assembly mounted on the second frame. The second frame includes a support frame 401 fixed to the substrate 101 and a pair of second mounting plates 402 mounted on the upper part of the support frame 401. The second mounting plates 402 are spaced apart from each other. The second support assembly includes a second support plate 403 horizontally fixed between two second mounting plates 402. The second support plate 403 has two second positioning grooves extending in the left and right direction to facilitate the installation of the second conveyor belt 404 described later. The height of the second support plate 403 is lower than the height of the second mounting plate 402. The inner side of the second mounting plate 402 can limit the glass slide and effectively ensure the movement trajectory of the glass slide. The second conveying mechanism includes a second drive shaft rotatably disposed at the right end of the two second mounting plates 402 and a second driven shaft rotatably disposed at the left end of the two second mounting plates 402. A pair of third pulleys corresponding to the second positioning grooves are spaced apart on the second drive shaft, and a pair of fourth pulleys corresponding to the third pulleys are spaced apart on the second driven shaft. A second conveyor belt 404 is wound around each pair of corresponding third and fourth pulleys. The second conveyor belt 404 conveys the glass slides to the designated recycling position.

[0047] In other embodiments of the present invention, such as Figure 6-7 As shown, the unwinding mechanism 400 also includes a second tensioning structure that puts the second conveyor belt 404 in a tensioned state. It includes a pair of first fixing blocks 405 arranged symmetrically in front and behind and a pair of second fixing blocks 406 arranged symmetrically in front and behind. A second tensioning spring 407 (a compression spring) is provided between the left and right adjacent first fixing blocks 405 and second fixing blocks 406. The front and rear ends of the second driven shaft extend outward through the second mounting plate 402, and the front and rear ends of the second driven shaft are respectively fixedly connected to the corresponding first fixing blocks 405. Each first fixing block 405 is provided with a pair of guide holes, and the second limiting screw 408 in each guide hole is fixedly connected to the second mounting plate 402. To ensure that the second driven shaft can move in the left and right directions, such as Figure 7 As shown, a pair of second guide and limiting grooves 409 extending in the left and right directions are provided at the left ends of the two second mounting plates 402, and the front and rear ends of the second driven shaft are engaged in the second guide and limiting grooves 409. When the second conveyor belt 404 is running, the first fixing block 405 can move left and right, realizing the real-time tensioning of the second conveyor belt 404.

[0048] like Figure 8-9 As shown, the automatic slide conveying device also includes a second power source 500, which is connected to the first conveying mechanism and the second conveying mechanism to realize synchronous conveying of the first conveying mechanism and the second conveying mechanism; The second power source 500 includes a motor mounting base 501 fixed to the substrate 101, and a second drive wheel 503 driven by a second motor 502 is mounted on the motor mounting base 501. The second power source 500 also includes a second driven wheel 504 mounted on a first drive shaft, and a third driven wheel 505 mounted on the second drive shaft. The second drive wheel 503, the second driven wheel 504, and the third driven wheel 505 are all synchronous belt pulleys, and a transmission belt (i.e., a second synchronous belt 506) is wound around the second drive wheel 503, the second driven wheel 504, and the third driven wheel 505. After the second motor 502 is started, it can drive the second synchronous belt 506 to rotate synchronously through the second drive wheel 503, realizing the synchronous conveying of the first conveyor belt 204 and the second conveyor belt 404, effectively ensuring the conveying spacing of the glass slides.

[0049] In other embodiments of the present invention: such as Figure 8 As shown, the second power source 500 also includes a first idler wheel 507 mounted on the motor mounting base 501, and a second idler wheel 508 and a third idler wheel 509 mounted on the second frame. The first idler wheel 507, the second idler wheel 508, and the third idler wheel 509 are all flange bearings. The first idler wheel 507 and the second idler wheel 508 are at the same height, and the third idler wheel 509 is at the same height as the second drive wheel 503, making the layout of the second synchronous belt 506 more reasonable and further ensuring the motion stability of the first conveyor belt 204 and the second conveyor belt 404.

[0050] like Figure 10-11 As shown, the slide conveying device also includes a limiting structure 600 mounted at the exit end of the slide feeding mechanism 200. The limiting structure 600 can not only limit the return path of the pusher claw 313 to prevent the pusher claw 313 from touching the slide below when it returns through the slide feeding mechanism 200, thus ensuring the integrity of the slide; it can also make the pusher claw 313 automatically fall after returning to its original position, so as to push the next slide.

[0051] like Figure 10-11As shown, the limiting structure 600 includes a limiting seat 601 mounted on the first frame and a limiting component mounted on the limiting seat 601. The limiting seat 601 is mounted at the outlet end of the first conveying mechanism. The limiting seat 601 has a U-shaped groove with an opening to the left, which not only reduces weight but also facilitates observation of the glass slide below. The limiting seats 601 located on both sides of the U-shaped groove have guide grooves 602 that correspond one-to-one with the pusher claw 313. The pusher claw 313 passes through the guide groove 602 downward and pushes the glass slide below to move towards the stage. The limiting structure 600 includes two limiting units; the limiting seat 601 near the guide groove 602 has an installation groove communicating with the guide groove 602. Each installation groove is provided with a limiting unit. The limiting unit includes a limiting member whose left end is rotatably set in the installation groove by a screw and a first reset member that makes the limiting member automatically reset. The limiting member is a limiting plate 603 extending along the length direction of the guide groove 602. The long side of the limiting plate 603 located outside the installation groove is a bevel, which blocks the left end of the guide groove 602. The bevel of the limiting plate 603 can ensure that the push claw 313 moves to the left. When the push claw 313 moves to the right during the return stroke, it can successfully block the push claw 313, so that the push claw 313 rotates upward and passes over the limit plate 603, preventing the push claw 313 from contacting the glass slide below during the return stroke, thereby effectively ensuring the integrity of the glass slide. The first reset component includes a connecting screw 604 disposed on the limiting seat 601. The connecting screw 604 is located near the left end of the limiting plate 603. A torsion spring 605 is fitted on the smooth part of the connecting screw 604 to automatically reset the limiting plate 603. The torsion spring 605 is fixedly connected to the other long side of the limiting plate 603. To further limit the rotation angle of the limiting plate 603 and ensure that the limiting plate 603 can be reset smoothly, a first limiting block 606 with an L-shaped structure is provided at the left end of the mounting groove to limit the limiting plate 603 and prevent the limiting plate 603 from rotating too much and affecting the reset. In other embodiments of the present invention, the limiting structure 600 further includes a glass slide separation plate 607 disposed on the right side of the limiting seat 601.

[0052] like Figure 12-13 As shown, the slide pushing mechanism 300 includes a mounting unit vertically mounted on the vibration-damping mounting structure 100; a first power source mounted on the mounting unit; a pushing component connected to the first power source; and a guide unit horizontally mounted on the mounting unit. During operation, the first power source can drive the pushing component to move back and forth along the guide unit.

[0053] like Figure 12-13As shown, the mounting unit includes a horizontally arranged fixed plate 301 and a vertical plate 303 fixed to the fixed plate 301 by corner brackets 302. The screws on the fixed plate 301 are screwed into the rubber shock-absorbing seat below to realize the shock-absorbing connection between the mounting unit and the base plate 101, which can buffer external forces. The guide unit is a guide rail 304 set on the top of the vertical plate 303. A second limiting block 305 is set on the vertical plate 303 on both the left and right sides of the guide rail 304. The two second limiting blocks 305 are both L-shaped structures and are symmetrically arranged to prevent the pushing component from detaching from the guide rail 304. The first power source is a synchronous belt drive pair driven by the first motor 306 (or it can be a linear power source such as a cylinder or hydraulic cylinder). Specifically, it includes the first motor 306 mounted on the vertical plate 303, the first driving wheel 307 driven by the first motor 306 and the first driven wheel 308 (which can be a flange bearing) rotatably mounted on the vertical plate 303. The first driving wheel 307 and the first driven wheel 308 are wound with a first synchronous belt 309. The pushing component is fixedly connected to the first synchronous belt 309 to realize the reciprocating translation of the pushing component. like Figure 12-13 As shown, the pushing component includes a connecting unit fixed to the first synchronous belt 309, a sliding unit disposed on the upper part of the connecting unit, and a pushing unit disposed at one end of the sliding unit. The pushing unit is mounted above the slide feeding mechanism 200, the stage F and the slide ejection mechanism 400 to facilitate relay pushing of the slide.

[0054] The connecting unit includes a vertically arranged connecting plate 310 and an upper clamping plate. The bottom of the connecting plate 310 extends horizontally to form a lower clamping plate that mates with the first synchronous belt 309. The upper clamping plate has a mounting groove that mates with the first synchronous belt 309. The upper clamping plate is snapped onto the upper surface of the upper section of the first synchronous belt 309. The upper clamping plate and the lower clamping plate are fixed together by screws, thus achieving a fixed connection between the connecting unit and the first synchronous belt 309. When the first synchronous belt 309 moves horizontally, it drives the connecting unit to move differently. The sliding unit includes a connecting block 311 horizontally disposed on the upper part of the connecting plate 310 and a slider disposed at the bottom of the connecting block 311. The lower surface of the slider has a groove that matches the guide rail 304, so that the slider is locked onto the guide rail 304. The pushing unit includes a fastener (mounting base 312) fixed to the connecting block 311 and a pair of pushing claws 313 spaced apart on the mounting base 312; the mounting base 312 has a U-shaped groove to facilitate observation of the glass slide below; The two mounting arms of the mounting base 312 have a mounting hole at the left end. A pusher pawl 313 is rotatably installed in each mounting hole (the upper part of the pusher pawl 313 is rotatably installed in the mounting hole via a pin), so that the pusher pawl 313 can rotate up and down along the horizontally set pin, laying the foundation for the return stroke of the pusher pawl 313. Each mounting hole has a mounting groove on its wall, and a magnet for adsorbing the pusher claw 313 is installed in the mounting groove. The adsorption of the magnet prevents the pusher claw 313 from vibrating during operation and improves the operational stability of the pusher claw 313.

[0055] like Figure 12 As shown, an origin sensor 314 is provided at the right end of the upright plate 303, and a sensing element (i.e., sensing plate 315) for triggering the origin sensor 314 is provided on the connecting plate 310. When the sensing plate 315 moves into the origin sensor 314, the origin sensor 314 transmits the detected signal to the control system. The control system processes the received data and sends a stop command to the first motor 306. Before detection, the pusher claw 313 is positioned above the stage F to facilitate the passage of the glass slides on the first conveyor belt 204 through the limiting structure 600. During detection, the pusher claw 313 returns to its original position after pushing each glass slide to facilitate the pushing of the next glass slide.

[0056] like Figure 14-16 As shown, the automatic slide conveying device also includes a pre-pressing structure 700 for fixing the slide to be inspected onto the stage F. The pre-pressing structure 700 includes a clamping assembly disposed on the stage F and a triggering assembly for triggering the clamping assembly to rise and fall. Specifically: the clamping assembly includes a lifting member, which is a lifting plate 701 horizontally disposed within the stage F, with both its front and rear ends extending outwards from the stage F; a guiding unit having multiple guide members (i.e., guide shafts 702) fixed on the lifting plate 701, with the upper part of each guide shaft 702 extending upwards through the stage F, and the guide shaft 702 slidingly engaging with the stage F to ensure smooth rise and fall; a pre-pressing unit having a pair of pre-pressing members (i.e., pre-pressing plates 703) symmetrically disposed at the front and rear ends of the lifting member, each pre-pressing plate 703 having a pre-pressing platform located above the stage, the pre-pressing platform pressing against the two short edges of the slide; and a reset unit to automatically reset the lifting member and the pre-pressing member to their original height.

[0057] like Figure 14-16 As shown, the reset unit includes four second reset components 704 (which are compression springs), with one compression spring mounted on each guide shaft 702. When the lifting plate 701 of the pressing assembly is lifted by force, the lifting plate 701 drives the pre-pressure plate 703 to rise synchronously, at which time the second reset components 704 are in a compressed state; when the force on the pressing assembly disappears, the spring force released by the second reset components 704 causes the lifting plate 701 and the pre-pressure plate 703 to automatically reset. After the pre-pressure plate 703 descends to its original position, it presses against the two short edges of the glass slide, improving the stability of the glass slide and reducing the interference of the external environment on the glass slide.

[0058] In other embodiments of the invention, such as Figure 14-16 As shown, the clamping assembly also includes a buffer pad 707 fixed to the bottom of the lifting plate 701. The buffer pad 707 is located at the mounting port of the platform F. When the lifting plate 701 descends, it can buffer the lifting plate 701 to ensure that the lifting plate 701 and the pre-pressure plate 703 descend stably.

[0059] like Figure 12 , 14 As shown, the triggering component includes a guide (i.e., guide block 705) located below the connecting block 311 and a rotating component 706 (using a flange bearing) located on the stage F. The guide block 705 has a guide channel that cooperates with the rotating component 706. The height of the guide block 705 is slightly higher than the height of the rotating component 706. When the guide block 705 passes the rotating component 706, the rotating component 706 is engaged in the guide channel, causing the lifting plate 701 and the pre-pressing plate 703 to rise synchronously, so that the slide pushing mechanism can push the slide onto the stage F. When the guide block 705 moves away from the rotating component 706, the lifting plate 701 and the pre-pressing plate 703 are automatically reset under the action of the second reset component, thereby pre-pressing the slide onto the stage F, improving the stability of the slide.

[0060] The working process and principle of this invention are briefly described below: Before inspecting the slide, ensure that the pusher claw 313 is moved above the stage F to prevent it from obstructing the movement of the slide below onto the stage F. Specifically, as follows: Figure 1 As shown; When a glass slide is placed at the inlet end of the first conveyor belt 204, the first glass slide positioning sensor 205 below detects the glass slide being placed in position. The control system sends an action command to the second motor 502. The second motor 502 drives the first conveyor belt 204 and the second conveyor belt 404 to move synchronously through the second synchronous belt 506, thereby realizing the equal-spacing conveying and unloading of the glass slide. When the glass slide moves to the exit end of the first conveyor belt 204, the second glass slide positioning sensor 206 transmits the detected glass slide signal to the control system. The control system sends a pause command to the second motor 502 and a return action command to the first motor 306, causing the pusher claw 313 to move to the right. When the push claw 313 moves back, when it passes the limit plate 603, the resistance of the limit plate 603 causes the push claw 313 to rotate upward to a certain height so as to smoothly pass over the limit plate 603. After the push claw 313 passes over the limit plate 603, it automatically falls under the action of gravity. When the origin sensor 314 detects the positioning information of the sensing plate 315, it indicates that the push claw 313 is at the origin position. Specifically, as shown below... Figure 17 As shown; The control system sends a push command to the first motor 306 (i.e., the pusher 313 moves to the left). The first motor 306 drives the pusher 313 to move to the left to push the glass sheet at the outlet end of the first conveyor belt 204 onto the platform F. When the pusher 313 passes over the limiting plate 603, since the limiting plate 603 has a bevel, the pusher 313 pushes the bevel of the limiting plate 603 to make the limiting plate 603 fit into the mounting groove so that the pusher 313 can pass smoothly. After the pusher 313 passes, the limiting plate 603 automatically resets under the action of the torsion spring 605. When the pusher claw 313 moves to the left to the exit end of the first conveyor belt 204, the pusher claw 313 pushes the glass slide to continue moving to the left. When the guide block 705 at the left end of the connecting block 311 moves to the bearing position, the bearing is locked on the guide block 705. When the guide block 705 continues to move to the left, the bearing drives the lifting plate 701 and the pressure block to move upward a certain height under the action of the guide block 705, so that the glass slide can successfully enter the stage F. After the guide block 705 leaves, the lifting plate 701 and the pressure block automatically descend and reset under the action of the second reset member 704. The two pressure blocks press the two short sides of the glass slide to provide stability for the glass slide. After the slide is pre-pressed, the microscope equipment focuses and photographs the slide. If multi-angle photography is required, the pusher claw 313 returns to the right, and the guide block 705, when moving back to the bearing position, locks the bearing in the guide block 705. The lifting plate 701 and the pressure block rise and move the height, and then the pusher claw 313 pushes the slide to the left. The pressure block is used to pre-press and fix the slide again to facilitate focusing and photography. After the slide is photographed, the slide ejection mechanism 400 and the slide feeding mechanism 200 move synchronously, so that the slide on the stage F moves to the second conveyor belt 404. At the same time, the slide pushing mechanism 300 resets to the right to push the next slide.

[0061] It should be noted that all directional indications (such as up, down, left, right, forward, backward, etc.) in the embodiments of the present invention are only used to interpret a specific posture (as shown in the attached diagram). Figure 1 The relative positions and movements of the components (as shown) are such that if the specific posture changes, the directional indication also changes accordingly. In this invention, unless otherwise explicitly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0062] Furthermore, in this invention, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the word "and / or" throughout the text means including three parallel solutions; taking "A and / or B" as an example, it includes solution A, solution B, or a solution that simultaneously satisfies A and B. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.
