Description

Technical Field

[0001] The present invention relates to the technical field of medical instruments, and in particular to a tablet pushing mechanism and a tablet pushing device. Background Art

[0002] When observing tiny objects, it is often necessary to make them into microscopic slide specimens for easy observation under a microscope. Microscopic slide specimens include slices, mounts and smears. Among them, smears are specimens made by evenly smearing liquid specimens (such as blood, bone marrow fluid, etc.) collected from organisms on a glass slide, which has been widely used in the medical field.

[0003] For example, when examining a patient, it is sometimes necessary to test the patient's blood. At this time, the blood needs to be evenly smeared on a glass slide to make a blood smear, and the prepared blood smear is placed under a microscope for observation. When making a blood smear, in order to avoid manual operation to contaminate the sample, a film pushing mechanism is often used to flatten the drop-shaped blood so that it can be evenly smeared on the glass slide.

[0004] Usually, in order to ensure that the pusher mechanism can push the blood flat, the pusher of the pusher mechanism is set at a certain angle to the glass slide, and it is necessary to ensure that the pusher fits tightly with the glass slide at all locations. However, when the pusher of the conventional pusher mechanism is not installed accurately or the glass slide is not placed flat, the pusher mechanism cannot adapt to changes in working conditions and cannot ensure that the pusher fits tightly with the glass slide at all locations, resulting in the blood not being pushed flat. Summary of the invention

[0053] See also Figure 1 An embodiment of the present invention provides a slide pushing device 100, which can push a drop-shaped liquid flat to form a sheet on a glass slide 200. Specifically, the slide pushing device 100 is applied to a fully automatic blood slide preparation instrument, and can push a drop-shaped blood flat to form a sheet on a glass slide 200 to prepare a blood smear. It should be understood that in other embodiments, the slide pushing device 100 can also be applied to other devices to prepare other types of slide specimens, which is not limited here.

[0054] The following is an example of a film pushing device 100 used in a fully automatic blood film pushing preparation instrument to describe the technical solution of the present application in detail. This embodiment is only used as an example and does not limit the technical scope of the present application. Furthermore, the drawings in the embodiments also omit unnecessary components to clearly show the technical features of the present application.

[0055] The slide pushing device 100 includes a slide pushing and wiping mechanism 10, a slide pushing mechanism 20, and a slide carrying mechanism 30. The slide carrying mechanism 30 is used to carry the slide glass 200. The slide pushing mechanism 20 is used to push the drop-shaped blood on the slide glass 200 flat. The slide pushing and wiping mechanism 10 is used to wipe the slide 25 of the slide pushing mechanism 20 to clean the slide 25. In other embodiments, the slide pushing device 100 may also omit the slide carrying mechanism 30, which is not limited here.

[0056] In one embodiment, the film pushing device 100 further includes a substrate 40, and the film pushing and wiping mechanism 10, the film pushing mechanism 20 and the film loading mechanism 30 are all arranged on the substrate 40, and the substrate 40 is the installation base of the film pushing and wiping mechanism 10, the film pushing mechanism 20 and the film loading mechanism 30. Specifically, the film loading mechanism 30 is arranged below the substrate 40, and the film pushing mechanism 20 and the film pushing and wiping mechanism 10 are arranged above the substrate 40. At the same time, the substrate 40 is penetrated with a through hole 41 along the thickness direction, and the film pushing mechanism 20 is connected with the film loading mechanism 30 through the through hole 41, so that the film pushing mechanism 20 pushes the blood on the glass slide 200. More specifically, at least a part of the glass loading mechanism 30 extends into the through hole 41, and when the glass slide 200 is placed on the glass loading mechanism 30, the upper surface of the glass slide 200 is flush with the upper surface of the substrate 40. Of course, in other embodiments, the entire slide mechanism 30 and the glass slide 200 may not protrude from the lower surface of the substrate 40. In this case, when the slide pushing mechanism 20 pushes the blood on the glass slide 200, its pusher 25 needs to extend into the through hole 41 to push the blood.

[0057] It is conceivable that in other embodiments, the substrate 40 may be omitted from the film pushing device 100 , and in this case, the film pushing mechanism 20 and the film pushing and wiping mechanism 10 may be directly connected to the film carrying mechanism 30 respectively.

[0058] In one implementation, the slide pusher 20 is fixed relative to the substrate 40, and the slide mechanism 30 pushes the slide 200 to move relative to the substrate 40. At this time, the slide 200 moves relative to the slide pusher 20 to achieve the effect of flattening the blood. Of course, in other embodiments, the slide 200 can also be set to be stationary, and the slide pusher 20 moves relative to the substrate 40 to achieve the effect of flattening the blood.

[0059] See also Figure 2 The slide mechanism 30 includes a fixed plate 31, a driving assembly 32 and a slide holder 33. The fixed plate 31 is fixedly connected to the base plate 40, the slide holder 33 is slidably connected to the fixed plate 31, and the driving assembly 32 is connected to the base plate 40 and / or the fixed plate 31, and is used to drive the slide holder 33 to reciprocate in the third direction relative to the fixed plate 31. When the driving assembly 32 drives the slide holder 33 to move forward in the third direction relative to the fixed plate 31, the pusher 25 of the slide pushing mechanism 20 can push the blood on the slide 200 placed on the slide holder 33 flat, and when the driving mechanism drives the slide holder 33 to move backward in the third direction, the slide holder 33 can return to the initial position to facilitate the preparation of the next blood smear.

[0060] See also Figure 3The driving assembly 32 includes a fourth driving motor 321, a driving wheel 322, a belt 323, a driven wheel 324 and a screw rod 325. The fourth driving motor 321 is connected to the fixed plate 31, the driving wheel 322 is connected to the driving end of the fourth driving motor 321, the screw rod 325 is connected to the fixed plate 31, the driven wheel 324 is connected to the protruding end of the screw rod 325 protruding from the fixed plate 31, and the belt 323 is sleeved outside the driving wheel 322 and the driven wheel 324. The glass slide holder 33 is threadedly connected to the screw rod 325 and is slidably matched with the fixed plate 31. In this way, when the fourth driving motor 321 rotates forward, the driving wheel 322 is driven to rotate, the belt 323 drives the driven wheel 324 to rotate, the screw rod 325 rotates forward, the glass slide holder 33 drives the glass slide 200 to move forward in the third direction, and the pusher 25 of the pusher mechanism 20 pushes the blood on the glass slide 200 flat. When the fourth driving motor 321 rotates in the reverse direction, the driving wheel 322 is driven to rotate, the belt 323 drives the driven wheel 324 to rotate, the screw rod 325 rotates in the reverse direction, and the slide holder 33 moves in the reverse direction in the third direction to return to the initial position, so as to facilitate the preparation of the next blood smear.

[0061] It is conceivable that in other embodiments, the driving component 32 may also be arranged in other ways, as long as it can achieve the purpose of driving the glass slide holder 33 to reciprocate relative to the fixed plate 31 .

[0062] The slide mechanism 30 further includes a first slide rail 34 and a first slider 35, one of which is fixedly connected to the fixed plate 31, and the other is fixedly connected to the glass slide holder 33, and the glass slide holder 33 is slidably matched with the fixed plate 31 through the first slider 35 and the first slide rail 34. In this specific embodiment, the first slide rail 34 is connected to the fixed plate 31, the first slider 35 is connected to the glass slide holder 33, and the glass slide holder 33 is threadedly connected to the screw rod 325 through the first slider 35.

[0063] The slide holder 33 includes a bottom plate 331, a first limiting plate 332 and a second limiting plate 333. The bottom plate 331 is threadedly connected to the screw rod 325, and the slide 200 is arranged on the bottom plate 331. The first limiting plate 332 and the second limiting plate 333 are both connected to the upper surface of the bottom plate 331 and extend in a direction away from the bottom plate 331. In the third direction, the first limiting plate 332 and the second limiting plate 333 are respectively located at two ends of the bottom plate 331, and the two ends of the slide 200 are respectively in contact with the first limiting plate 332 and the second limiting plate 333. The distance between the first limiting plate 332 and the second limiting plate 333 determines the length of the slide 200, that is, the arrangement of the second limiting plate 333 and the second limiting plate 333 plays a role in limiting the length of the slide 200.

[0064] In the second direction perpendicular to the third direction, that is, in the direction perpendicular to the connecting direction of the first limiting plate 332 and the second limiting plate 333, the bottom plate 331 is provided with a taking groove 3311′ on both sides thereof. When placing the glass slide 200 on the glass slide holder 33, a person's hand can be inserted into the taking groove 3311′, so as to facilitate placing the glass slide 200 on the glass slide holder 33. When the glass slide 200 on the glass slide holder 33 needs to be removed, a person's hand can also be inserted into the taking groove 3311′, so as to facilitate removing the glass slide 200 placed on the glass slide holder 33. In this way, by providing the taking groove 3311′, it is convenient to take and place the glass slide 200 in the width direction of the glass slide 200.

[0065] See also Figure 4 In one embodiment, the push-piece mechanism 20 includes a mounting seat 21, a rotating block 22 and a first driving member 23. The mounting seat 21 is mounted on the substrate 40. The rotating block 22 and the first driving member 23 are both mounted on the mounting seat 21. The rotating block 22 is pivotally connected to the mounting seat 21. The first driving member 23 is constructed to be able to drive the rotating block 22 to rotate relative to the mounting seat 21 around a first axis.

[0066] See also Figure 5 The push-piece mechanism 20 further includes a mounting block 24 for mounting the push-piece 25. When the first driving member 23 drives the rotating block 22 to rotate relative to the mounting seat 21 about the first axis, the rotating block 22 drives the mounting block 24 to rotate, so that the push-piece 25 mounted on the mounting block 24 can be in the push-piece position (see Figure 6 ), that is, the inclination angle between the push piece 25 and the slide glass 200 can be within the range of 0°-90°.

[0067] Specifically, the mounting block 24 is movably connected to the rotating block 22. Figure 7 The push sheet mechanism 20 further includes a first elastic member 26, which is disposed between the rotating block 22 and the mounting block 24, and the mounting block 24 can swing relative to the rotating block 22. Through the above arrangement, when the push sheet 25 contacts the glass slide 200, an interaction force is generated between the glass slide 200 and the push sheet 25, and the push sheet 25 transmits the force to the mounting block 24, and the mounting block 24 compresses the first elastic member 26. The mounting block 24 and the push sheet 25 are acted upon by the elastic restoring force of the first elastic member 26, thereby ensuring that the push sheet 25 and the glass slide 200 are closely fitted. That is, by providing the first elastic member 26 and the mounting block 24 being movably connected to the rotating block 22, when the installation position of the push sheet 25 is inaccurate or the glass slide 200 is unevenly placed, the push sheet mechanism 20 can be adjusted according to the change of the working conditions to ensure that the push sheet 25 and the glass slide 200 are closely fitted, thereby flattening the blood, and the self-adaptive effect of the push sheet mechanism 20 is good.

[0068] Specifically, the first elastic member 26 is disposed between the mounting block 24 and the rotating block 22 in the first direction, and the first direction intersects with the extension direction of the first axis. It should be noted that the first direction intersects with the extension direction of the first axis means that the first direction and the extension direction of the first axis are located in the same plane, the first direction and the extension direction of the first axis intersect in the plane, or the first direction and the extension direction of the first axis can intersect in three-dimensional space.

[0069] It should be noted that the above-mentioned push-piece position is not a unique fixed position, and any position can be selected as needed as long as the inclination angle between the push-piece 25 and the slide glass 200 is within the range of 0°-90°.

[0070] according to Figure 1 The middle direction is the reference standard, the first direction is the vertical direction, the second direction is the line direction of the lower left corner and the upper right corner, and the third direction is the line direction of the upper left corner and the lower right corner. The first direction, the second direction and the third direction are perpendicular to each other, that is, the first direction is Figure 1 The Z direction in the second direction is Figure 1 The Y direction in the third direction is Figure 1 The X direction in .

[0071] Continue reading Figure 4 The first driving member 23 includes a first driving motor 231 and a coupling 232. The first driving motor 231 is fixedly connected to the rotating block 22 via the coupling 232. The push-piece mechanism 20 also includes two first rotating shafts 27 (see Figure 7 ), two first rotating shafts 27 are fixedly connected to the two ends of the rotating block 22, and one of the first rotating shafts 27 is inserted into the mounting seat 21 and fixedly connected to the first driving motor 231 through the coupling 232, and the other first rotating shaft 27 is inserted into the fixing seat 11 and is rotatably connected thereto. The first driving motor 231 drives the first rotating shaft 27 to rotate through the coupling 232, and the first rotating shaft 27 drives the rotating block 22 to rotate relative to the mounting seat 21, and the first axis is the central axis of the first rotating shaft 27.

[0072] Furthermore, the mounting block 24 is configured to be rotatable relative to the rotating block 22 around a second axis, and an extension direction of the second axis intersects with an extension direction of the first axis in the same plane or in a three-dimensional space.

[0073] Continue reading Figure 7 and Figure 8The first elastic member 26 includes a first sub-elastic member 261 and a second sub-elastic member 262. In the extension direction of the first axis, the first sub-elastic member 261 and the second sub-elastic member 262 are distributed on both sides of the second axis. In this way, when the push sheet 25 contacts the glass slide 200, an interaction force is generated between the glass slide 200 and the push sheet 25. The push sheet 25 transmits the force to the mounting block 24, and the mounting block 24 transmits the force to the first sub-elastic member 261 and / or the second sub-elastic member 262. The first sub-elastic member 261 and / or the second sub-elastic member 262 are elastically deformed by the force to further ensure that the push sheet 25 is closely attached to the glass slide 200, thereby ensuring the flattening effect of the blood.

[0074] Specifically, the first sub-elastic member 261 and the second sub-elastic member 262 are both springs, and a mounting hole is provided on at least one of the mounting block 24 and the rotating block 22, and parts of the first sub-elastic member 261 and the second sub-elastic member 262 are provided in the mounting hole. More specifically, both the mounting block 24 and the rotating block 22 are provided with mounting holes, and both ends of the first sub-elastic member 261 and the second sub-elastic member 262 are respectively provided in the corresponding mounting holes. Of course, in other embodiments, the first sub-elastic member 261 and the second sub-elastic member 262 can also be made of rubber, which is not limited here.

[0075] See also Figure 4 and Fig. 9 The push-piece mechanism 20 includes a second rotating shaft 28, the rotating block 22 is L-shaped, one end of the mounting block 24 is arranged at the right-angle groove of the L-shape, the first elastic member 26 is arranged between one end of the L-shape and the mounting block 24, and the second rotating shaft 28 is connected to the other end of the L-shape. A rotating shaft hole is arranged at one end of the L-shape, and the second rotating shaft 28 is passed through the rotating shaft hole to realize the rotating connection between the mounting block 24 and the rotating block 22, and the second axis is the central axis of the second rotating shaft 28.

[0076] In one embodiment, the push sheet mechanism 20 further includes a push sheet 25, which is mounted on the mounting block 24. Specifically, the push sheet 25 is detachably connected to the mounting block 24 to facilitate replacement of the push sheet 25. It is conceivable that in some other embodiments, the push sheet 25 can also be integrally formed with the mounting block 24, which is not limited here.

[0077] See also Fig. 9The mounting block 24 includes a first body 241 and a clamping piece 242. The first body 241 is rotatably connected to the rotating block 22. The first elastic member 26 is disposed between the first body 241 and the rotating block 22 in the first direction. The clamping piece 242 is mounted on the first body 241. A clamping opening is formed between the clamping piece 242 and the first body 241. The push piece 25 is pressed between the clamping piece 242 and the first body 241 from the clamping opening. The clamping piece 242 is elastic. Since the clamping piece 242 is elastic, when the push piece 25 is mounted on the mounting block 24, the clamping piece 242 is bent to elastically deform so that the push piece 25 is mounted on the mounting block 24. When the push piece 25 is mounted on the mounting block 24, the push piece 25 is firmly fixed on the mounting block 24 under the elastic force of the clamping piece 242. In some other embodiments, the push piece 25 can be installed on the mounting block 24 by other methods, such as additionally providing a clamping block, and screws passing through the clamping block and the first body 241 to clamp the push piece 25 on the first body 241 .

[0078] See also Fig.10 The first body 241 includes a first sub-body 2411 and a second sub-body 2412 connected to each other, the first elastic member 26 is disposed between the first sub-body 2411 and the rotating block 22, the second sub-body 2412 is connected to the first sub-body 2411 and the two are arranged at an obtuse angle, the clamping piece 242 is disposed on the second sub-body 2412, the push piece 25 is disposed between the second sub-body 2412 and the clamping piece 242, and the plane where the push piece 25 is located is parallel to the plane where the second sub-body 2412 is located. Since the first sub-body 2411 and the second sub-body 2412 are arranged at an obtuse angle, when the first sub-body 2411 is arranged vertically, it can be ensured that the angle between the plane where the second sub-body 2412 is located, that is, the plane where the push piece 25 is located and the plane where the glass slide 200 is located is within the range of 0°-90°, so as to facilitate the flattening of the blood on the glass slide 200.

[0079] Continue reading Figure 5 The mounting seat 21 includes a first mounting plate 211 and a second mounting plate 212. The first mounting plate 211 is fixedly connected to the base plate 40. Of course, in other embodiments, the first mounting plate 211 can also be slidably connected to the base plate 40. The second mounting plate 212 is slidably connected to the first mounting plate 211. The rotating block 22 and the first driving member 23 are both mounted on the second mounting plate 212. The push-piece mechanism 20 also includes a second elastic member 29 (see Figure 7 ), the second elastic member 29 is disposed between the first mounting plate 211 and the second mounting plate 212. Specifically, the second mounting plate 212 is slidably connected to the first mounting plate 211 in the first direction, and the second elastic member 29 is disposed between the first mounting plate 211 and the second mounting plate 212 in the first direction.

[0080] Through the above arrangement, when the push piece 25 contacts the glass slide 200, the interaction force generated between the push piece 25 and the glass slide 200 is transmitted to the second mounting plate 212 in sequence through the push piece 25, the mounting block 24 and the rotating block 22. The second mounting plate 212 transmits the above force to the second elastic member 29. The second mounting plate 212 slides relative to the first mounting plate 211, and the second elastic member 29 elastically deforms and exerts a reverse force on the second mounting plate 212. Under the action of the above reverse force, it is ensured that the push piece 25 and the glass slide 200 fit more closely.

[0081] Continue reading Figure 5 The sheet pushing mechanism 20 includes a second slide rail 210 and a second slider 220. One of the second slide rail 210 and the second slider 220 is disposed on the first mounting plate 211, and the other is disposed on the second mounting plate 212. The second slider 220 cooperates with the second slide rail 210 to realize a sliding connection between the second mounting plate 212 and the first mounting plate 211.

[0082] The sheet pushing mechanism 20 further includes a guide member 230 , one end of which is fixedly connected to the second mounting plate 212 , and the other end of the guide member 230 is guided and matched with the first mounting plate 211 in the first direction, so that the guide member 230 serves to guide the second mounting plate 212 .

[0083] Continue reading Figure 4 The guide member 230 includes a first connecting portion 240 and a limiting portion 250. One end of the first connecting portion 240 is fixedly connected to the second mounting plate 212, and the other end of the limiting portion 250 is fixedly connected to the first connecting portion 240. The limiting portion 250 is constructed to limit the movement of the second mounting plate 212 to a preset position relative to the first mounting plate 211 to prevent the second mounting plate 212 from being separated from the first mounting plate 211 under the action of gravity or other combined forces.

[0084] Furthermore, the second elastic member 29 is a spring, the first connecting portion 240 is a guide column, and the second elastic member 29 is sleeved outside the guide column, so that the wire member 230 not only plays a guiding role but also plays a role in limiting the second elastic member 29. It should be understood that in other embodiments, the second elastic member 29 can also be arranged at other positions, and the second elastic member 29 can also be made of rubber.

[0085] Continue reading Figure 7In one embodiment, the push-piece mechanism 20 further includes a first induction switch 260 and a first induction sheet 270. The first induction switch 260 is mounted on the mounting seat 21. The first induction sheet 270 is mounted on the driving end of the first driving member 23 or the rotating block 22 and can rotate relative to the mounting seat 21 following the driving end or the rotating block 22. The first induction switch 260 is configured to sense the rotation angle of the first induction sheet 270. By setting the first induction switch 260 and the first induction sheet 270, the first induction switch 260 can sense the rotation angle of the first induction sheet 270 and transmit the signal to the controller. The controller controls the rotation angle of the first driving motor 231, thereby controlling the rotation angle of the push-piece 25 to ensure that the push-piece 25 is located at the push-piece position.

[0086] See also Fig.11 In one embodiment, the first driving member 23 can drive the rotating block 22 to rotate relative to the second mounting plate 212, thereby driving the mounting block 24 and the push piece 25 to rotate relative to the second mounting plate 212, so that the push piece 25 is in a cleaning position. In the cleaning position, the push piece wiping mechanism 10 can wipe the push piece 25 of the push piece mechanism 20.

[0087] Further, the push-piece wiping mechanism 10 and the push-piece wiping mechanism 20 can generate relative movement to achieve the effect that the push-piece wiping mechanism 10 wipes the push-piece 25. In a specific embodiment, the push-piece wiping mechanism 20 is fixed to the substrate 40, and the push-piece wiping mechanism 10 moves relative to the substrate 40 to wipe the push-piece 25. Of course, in other embodiments, the push-piece wiping mechanism 10 and the substrate 40 can also be fixed, and the push-piece wiping mechanism 20 moves relative to the substrate 40 to wipe the push-piece 25, which is not limited here.

[0088] See also Fig.12 and Fig.13 The push-piece wiping mechanism 10 includes a fixed seat 11 and a wiping unit 12. The fixed seat 11 is fixedly connected to the base plate 40. The wiping unit 12 is slidably connected to the fixed seat 11. The wiping unit 12 is provided with a wiping member 13 for wiping the push piece 25 of the push-piece mechanism 20. The push-piece wiping mechanism 10 also includes a second driving member 14 (see Fig.14 ), the second driving member 14 is mounted on the fixed seat 11, and is configured to drive the wiping unit 12 to reciprocate relative to the fixed seat 11 to wipe the push piece 25 of the push piece mechanism 20.

[0089] In this embodiment, the wiping unit 12 drives the wiping member 13 to reciprocate relative to the fixed seat 11 to wipe the push piece 25 of the push piece mechanism 20, which takes less time than the ultrasonic cleaning of the push piece in the prior art.

[0090] Furthermore, a wiping position is provided on the wiping unit 12, and the wiping member 13 includes a wiping belt 131, and a plurality of wiping portions 1311 are formed on the wiping belt 131. The wiping belt 131 can move relative to the wiping unit 12 so that the plurality of wiping portions 1311 are selectively arranged at the wiping position. The movement direction of the wiping belt 131 is perpendicular to the movement direction (second direction) of the wiping unit 12. That is, in this embodiment, the push-piece mechanism 20 is fixed relative to the substrate 40, and the wiping unit 12 of the push-piece wiping mechanism 10 moves relative to the substrate 40 to drive the wiping portion 1311 to reciprocate in the second direction to wipe the push-piece 25. Each time the push-piece 25 is used, a different wiping portion 1311 is used for wiping, thereby avoiding cross infection.

[0091] Furthermore, the wiping portion 1311 can carry a cleaning medium, and the cleaning medium is injected onto the wiping portion 1311, and the cleaning medium dissolves the liquid adhering to the push sheet 25, so as to further improve the cleaning effect of the push sheet 25 of the push sheet mechanism 20, and the amount of the cleaning medium is less than that of the ultrasonic cleaning method in the prior art. Of course, in other embodiments, the cleaning medium can also be directly injected onto the push sheet 25, and the cleaning medium dissolves the liquid adhering to the push sheet 25, and the wiping portion 1311 only has a wiping effect.

[0092] Continue reading Fig.14 The push-piece wiping mechanism 10 further includes a liquid injection part 110, which is configured to be able to inject a cleaning medium onto the wiping member 13 or the push-piece 25. Specifically, the liquid injection part 110 is disposed on the fixing seat 11 or the wiping unit 12 and is a liquid injection tube. When it is necessary to spray the cleaning medium onto the wiping portion 1311, the liquid injection tube is connected to the external pump body, and the external pump body draws the cleaning medium into the liquid injection tube, and the liquid injection tube sprays the cleaning medium onto the wiping portion 1311.

[0093] In a specific embodiment, the second direction is perpendicular to the third direction, that is, the first direction is perpendicular to the length direction of the glass slide 200 and parallel to the width direction of the glass slide 200 and the width direction of the push piece 25, so the push piece wiping mechanism 10 can wipe the push piece 25 in the width direction.

[0094] Continue reading Fig.12The push-piece wiping mechanism 10 further includes a third slide rail 15 and a third slider 16, one of which is disposed on the fixed seat 11, and the other is disposed on the wiping unit 12, and the third slide rail 15 and the third slider 16 are slidably matched to realize the sliding connection between the wiping unit 12 and the fixed seat 11. The second driving member 14 includes a second driving motor 141, and the push-piece wiping mechanism 10 further includes a first connecting rod 191 and a second connecting rod 192, one end of the first connecting rod 191 is fixedly connected to the driving shaft of the second driving member 14, the other end of the first connecting rod 191 is hinged to one end of the second connecting rod 192, and the other end of the second connecting rod 192 is hinged to the wiping unit 12. In this way, when the second driving member 14 is working, through the cooperation of the first connecting rod 191 and the second connecting rod 192, and under the guidance cooperation of the third slide rail 15 and the third slider 16, the wiping unit 12 is driven to reciprocate in the second direction to realize the effect of wiping the push-piece 25.

[0095] The push-piece wiping mechanism 10 also includes a second sensing switch 17 and a second sensing sheet 18. Specifically, the second sensing sheet 18 is arranged at the driving end of the second driving member 14 or on the first connecting rod 191, and the second sensing switch 17 is arranged on the fixed seat 11. The second sensing switch 17 can sense the rotation angle of the second sensing sheet 18, thereby controlling the rotation angle of the second driving motor 141 to control the number of reciprocating motions of the wiping unit 12 in the second direction.

[0096] Continue reading Figure 1 , Figure 12-13 and Figure 15-16 In one embodiment, the wiping member 13 further includes a tape box 132, and a receiving chamber 122 is provided in the wiping unit 12, and the tape box 132 is received in the receiving chamber 122. The tape box 132 is provided with a receiving chamber, and the wiping member 13 further includes a first winding member 135 and a second winding member 136, and at least a part of the first winding member 135 and the second winding member 136 is provided in the receiving chamber, one end of the wiping tape 131 is connected to the first winding member 135, and the other end of the wiping tape 131 is connected to the second winding member 136, and the wiping tape 131 can move relative to the tape box 132 by means of the first winding member 135 and the second winding member 136.

[0097] The wiping member 13 also includes a positioning block 133 , which is disposed on the tape box 132 . The tape box 132 is also provided with a first opening 1321 communicating with the accommodating cavity. When the wiping tape 131 is wound from the first winding member 135 to the second winding member 136 , it passes through the first opening 1321 and abuts against the positioning block 133 .

[0098] When the push sheet 25 of the push sheet mechanism 20 needs to be cleaned, the push sheet 25 contacts the wiping tape 131, and under the force applied by the push sheet 25 to the wiping tape 131, the wiping tape 131 is clamped and positioned between the positioning block 50 and the push sheet 25, thereby increasing the friction between the push sheet 25 and the wiping tape 131. When the friction between the push sheet 25 and the wiping tape 131 increases, the cleaning effect on the push sheet 25 of the push sheet mechanism 20 is improved.

[0099] It should be noted that the wiping tape 131 passes through the first opening 1321 and abuts against the positioning block 133 when the first winding member 135 is wound on the second winding member 136, including the following situations:

[0100] In one embodiment, the wiping tape 131 is wound from the first winding member 135 on the second winding member 136, passes through the first opening 1321, passes through the accommodating cavity, abuts against the positioning block 133, and re-enters the accommodating cavity from the first opening 1321. In another embodiment, the wiping tape 131 is wound from the first winding member 135 on the second winding member 136, passes through the first opening 1321, passes through the accommodating cavity, abuts against the positioning block 133, and re-enters the accommodating cavity from other openings. In yet another embodiment, the wiping tape 131 is wound from the first winding member 135 on the second winding member 136, passes through other openings, passes through the accommodating cavity, abuts against the positioning block 133, and re-enters the accommodating cavity from the first opening 1321.

[0101] It should also be explained here that the above-mentioned wiping tape 131 is wound from the first winding member 135 on the second winding member 136 through the first opening 1321 to pass through the accommodating cavity and abut against the positioning block 133, which means that the wiping tape 131 partially abuts against the positioning block 133, so that when cleaning the push piece 25, the wiping tape 131 is clamped and positioned between the positioning block 133 and the push piece 25.

[0102] In one embodiment, the tape box 132 is a hollow rectangular structure, that is, the cross-sectional shape of the tape box 132 is a rectangle, the first winding member 135 and the second winding member 136 are both flat discs, and the axial directions of the first winding member 135 and the second winding member 136 are parallel to the thickness direction of the tape box 132, and the first winding member 135 and the second winding member 136 are arranged side by side in the tape box 132.

[0103] It should be noted here that since the wiping tape 131 is wound around the outer periphery of the first winding member 135 and the second winding member 136, and since the second direction is the width direction of the wiping tape 131, the second direction is also the thickness direction of the tape box 132, or the axial direction of the first winding member 135 and the second winding member 136.

[0104] Specifically, the tape box 132 includes a first half shell 1324 and a second half shell 1325 which are separately arranged. The first half shell 1324 and the second half shell 1325 are spliced ​​to form the tape box 132. Such an arrangement facilitates the assembly of the first winding member 135, the second winding member 136 and the wiping tape 131.

[0105] In one embodiment, the first winding member 135 and the second winding member 136 are all arranged in the accommodating cavity, the first winding member 135 is provided with a first mounting hole, the second winding member 136 is provided with a second mounting hole, and the position of the tape box 132 corresponding to the first mounting hole is provided with a first through-hole, and the position corresponding to the second mounting hole is provided with a second through-hole. Such arrangement facilitates the external driving mechanism to be arranged in the first mounting hole from the first through-hole, and in the second mounting hole from the second through-hole, so as to drive the wiping tape 131 to rotate relative to the tape box 132. It should be understood that in other embodiments, it is also possible to arrange part of the first winding member 135 and the second winding member 136 in the accommodating cavity, the remaining part of the first winding member 135 passes through the first through-hole, and the remaining part of the second winding member 136 passes through the second through-hole to connect with the external driving mechanism, so as to drive the wiping tape 131 to rotate relative to the tape box 132.

[0106] Furthermore, during the movement of the wiping tape 131 relative to the tape box 132 , one of the first winding member 135 and the second winding member 136 for winding up the wiping tape 131 acts as an active member, and the other acts as a driven member by virtue of the pulling action of the wiping tape 131 .

[0107] See also Fig.17 The push-piece wiping mechanism 10 also includes a third driving member 120, which includes a third driving motor 130 and a passive shaft 140. The third driving motor 130 has an active shaft 150, a first winding member 135 is connected to the active shaft 150, and a second winding member 136 is connected to the passive shaft 140. The third driving motor 130 drives the first winding member 135 to reel in the wiping tape 131, and at this time, the second winding member 136 releases the wiping tape 131 under the pulling action of the wiping tape 131, so that the multiple wiping parts 1311 are selectively set at the wiping position. It should be understood that in other embodiments, the second winding member 136 can also be connected to the active shaft 150, and the second winding member 136 can be connected to the passive shaft 140, which is not limited here.

[0108] Continue reading Fig.18 and Fig.19The wiping unit 12 includes a first connecting plate 123 and a second connecting plate 124. The first connecting plate 123 is slidably connected to the fixing seat 11, and the second connecting plate 124 is movably connected to the first connecting plate 123. The third driving member 120 is disposed on the first connecting plate 123, and the accommodating cavity 122 is disposed on the second connecting plate 124. The second connecting plate 124 can be switched between a first position and a second position relative to the first connecting plate 123. In the first position, the third driving member 120 restricts the tape box 132 to the second connecting plate 124 (see Fig.18 ), in the second position, the third driving member 120 allows the tape cassette 132 to be separated from the second connecting plate 124 (see Fig.19 ).

[0109] In the first position, the third driving member 120 limits the separation of the tape box 132 from the second connecting plate 124, ensuring that the tape box 132 is firmly connected to the second connecting plate 124 when in normal working state; in the second position, the third driving member 120 allows the tape box 132 to separate from the second connecting plate 124, thereby facilitating the replacement of the tape box 132.

[0110] When the second connecting plate 124 is in the first position, the active shaft 150 passes through the first penetration hole and is penetrated in the first mounting hole, and the passive shaft 140 passes through the second penetration hole and is penetrated in the second mounting hole. In this specific embodiment, it is precisely because when the second connecting plate 124 is in the first position, the active shaft 150 is penetrated in the first mounting hole, and the passive shaft 140 is penetrated in the second mounting hole, that the active shaft 150 and the passive shaft 140 will restrict the separation of the tape box assembly from the second connecting plate 124; and when the second connecting plate 124 is in the second position, the active shaft 150 is separated from the first winding member 135, and the passive shaft 140 is separated from the second winding member 136, and at this time the third driving member 120 will not restrict the separation of the tape box assembly from the second connecting plate 124.

[0111] Continue reading Fig.15 and Fig.16 In one embodiment, the wiping member 13 further comprises an elastic pressing piece 137, which is pressed on the driven member to prevent the driven member from rotating and causing the wiping tape 131 to be automatically released from the driven member. Specifically, the tape box 132 is provided with a pressing opening connected to the receiving cavity, and the pressing piece 137 is pressed on the driven member through the pressing opening.

[0112] It should be understood that in other embodiments, the connection method between the first winding member 135 and the second winding member 136 and the third driving member 120 is not limited to this. For example, the first winding member 135 and the second winding member 136 can also be arranged to extend from the belt box 132 and be connected to the third driving member 120.

[0113] Continue reading Fig.18 and Fig.19The sliding plate 122 further includes a mounting piece 125 and a matching piece 126. The mounting piece 125 is movably connected to one of the first connecting plate 123 and the second connecting plate 124, and the matching piece 126 is connected to the other of the first connecting plate 123 and the second connecting plate 124. The matching piece 126 is movably connected to the mounting piece 125 so as to be switchable between a third position and a fourth position relative to the mounting piece 125. In the third position, the matching piece 126 cooperates with the mounting piece 125 to limit the second connecting plate 124 to the first position. In the fourth position, the matching piece 126 cooperates with the mounting piece 125 to limit the second connecting plate 124 to the second position. Through the above arrangement, it is possible to ensure that the second connecting plate 124 is stably in the first position and the second position.

[0114] Specifically, one end of the mounting plate 125 is hinged to the second connecting plate 124, and the other end is provided with an L-shaped limiting groove 1251 (see Fig. 20 ), the matching piece 126 is a clamping column connected to the first connecting plate 123, the clamping column extends into the limiting groove 1251, and the clamping column can move in the limiting groove 1251. When the clamping column moves to the limit position (third position) at one end in the limiting groove 1251, the clamping column limits the second connecting plate 124 to the first position, and when the clamping column moves to the limit position (fourth position) at the other end in the limiting groove 1251, the clamping column limits the second connecting plate 124 to the second position.

[0115] In one embodiment, the first opening 1321 is opened at a right angle vertex of the tape box 132, and the positioning block 133 is disposed at the same right angle vertex of the tape box 132, and a right angle portion 1331 is formed on the positioning block 133 (see Fig.21 and Fig. 22 ), the wiping portion 1311 can be bent by the force applied by the push piece 25 and abut against the right-angle portion 1331, so as to facilitate the positioning of the wiping portion 1311 and the push piece 25, thereby making it easier to wipe the push piece 25.

[0116] Continue reading Fig.13 , and see Fig.23 In one embodiment, the positioning block 133 is pivotally connected to the tape box 132, and the positioning block 133 can swing relative to the tape box 132. Specifically, the positioning block 133 is pivotally connected to the tape box 132 via a first axis, and the rotation axis of the positioning block 133 relative to the tape box 132 is parallel to the rotation axis of the first winding member 135 and the second winding member 136. Fig.13The wiping member 13 also includes a limiter (not shown in the figure) for limiting the swing position of the positioning block 133 relative to the tape box 132. The limiter includes a first sub-limiter 1381 and a second sub-limiter 1382. In the swing direction of the positioning block 133 relative to the tape box 132, the first sub-limiter 1381 and the second sub-limiter 1382 are respectively arranged on both sides of the positioning block 133. In this way, when the push piece 25 applies a force to the wiping portion 1311, since the positioning block 133 can rotate relative to the tape box 132, it is convenient for the push piece 25 to push the wiping portion 1311 to abut against the right-angle portion 1331, which is convenient for positioning the wiping portion 1311 and improving the adaptive ability of the positioning block 133.

[0117] The first sub-limiting member 1381 and / or the second sub-limiting member 1382 are elastic. When the first sub-limiting member 1381 and / or the second sub-limiting member 1382 are elastic, when the push piece 25 releases the positioning block 133, the positioning block 133 can automatically reset under the action of the elastic restoring force.

[0118] The first sub-limiting member 1381 is elastic. Specifically, the first sub-limiting member 1381 is a torsion spring, which includes a second body and a first end and a second end respectively connected to the second body, and the second body is connected to the tape box 132. More specifically, the second body is sleeved on a second shaft protruding from the tape box 132, the first end abuts against the tape box 132, and the second end abuts against the positioning block 133. In this way, when the push piece 25 applies a force to the wiping tape 131, the positioning block 133 swings relative to the tape box 132 under the drive of the wiping tape 131, and the positioning block 133 causes the torsion spring to deform elastically, thereby fine-tuning the position of the positioning block 133 relative to the tape box 132, so that the push piece 25 abuts against the wiping portion 1311 and the right-angle portion 1331, which is convenient for positioning the wiping portion 1311 and improving the adaptive ability of the positioning block 133.

[0119] The second sub-limiting member 1382 is a protrusion protruding from the tape box 132 to cooperate with the first sub-limiting member 1381 to limit the position of the positioning block 133 relative to the tape box 132. Specifically, the second sub-limiting member 1382 is protruding from the second half shell 16.

[0120] Continue reading Fig. 22In one embodiment, an elastic element 134 is provided on the positioning block 133, and the elastic element 134 is used to abut against the wiping belt 131. Further, the elastic element 134 has a first abutting plane 1341 and a second abutting plane 1342 respectively located on both sides of the right-angle portion 1331, and the wiping belt 131 abuts against both the first abutting plane 1341 and the second abutting plane 1342. With this arrangement, when the push sheet 200 needs to be cleaned, the elastic element 134 is elastically deformed to apply an elastic restoring force to the push sheet 25, so that the wiping belt 131 is more tightly clamped between the positioning block 133 and the push sheet 25, thereby increasing the friction between the push sheet 25 and the wiping portion 1311 and improving the wiping effect.

[0121] Specifically, the elastic element 134 is made of rubber material, and the elastic element 134 is integrally formed with the positioning block 133. It should be understood that in other embodiments, the elastic element 134 is not limited to being made of rubber, and the elastic element 134 can also be separately provided with the positioning block 133.

[0122] See also Fig.13 , Fig.16 and Fig.23 In one embodiment, the wiping member 13 further includes a first tape guide 1391 and a second tape guide 1392. In the moving direction of the wiping tape 131 relative to the tape box 132, the first tape guide 1391 and the second tape guide 1392 are respectively located upstream and downstream of the positioning block 133. In this way, when the wiping tape 131 enters and exits the first opening 1321, the first tape guide 1391 and the second tape guide 1392 can limit the angle of the wiping tape 131 and facilitate the tensioning of the wiping tape 131. Specifically, the first tape guide 1391 and the second tape guide 1392 are both arranged adjacent to the first opening 1321.

[0123] In one embodiment, the tape box 132 is further provided with a second opening 1322 communicating with the receiving cavity, and the wiping member 13 further includes a third tape guide 1393, which is arranged on the tape box 132. When the wiping tape 131 is wound from the first winding member 135 to the second winding member 136, it passes through the second opening 1322 and abuts against the third tape guide 1393. In this way, the third tape guide 1393 can play a role in supporting the wiping tape 131 together with the first tape guide 1391 and the second tape guide 1392. The push-piece wiping mechanism 10 also includes a counting wheel 1120 (see FIG. 1 ) arranged on the first connecting plate 123. Fig.14 ), the wiping tape 131 is clamped between the third tape guide 1393 and the counting wheel 1120. When the wiping tape 131 rotates relative to the tape box 132, the counting wheel 1120 rotates under the friction force applied to it by the wiping tape 131, thereby the length of movement of the wiping tape 131 is determined according to the number of revolutions it rotates.

[0124] Continue reading Fig.14The push-piece wiping mechanism 10 also includes a counting disk 1130 and a third sensing switch 1140. The third sensing switch 1140 is arranged on the first connecting plate 123. The counting disk 1130 is transmission-connected to the counting wheel 1120. The third sensing switch 1140 can sense the number of rotations of the counting disk 1130 to transmit the signal to the controller. The controller controls the rotation angle of the third driving member 120 to control the moving length of the wiping belt 131.

[0125] Continue reading Fig.13 In a specific embodiment, in the length direction of the tape box 132, the third tape guide 1393 and the positioning block 133 are respectively arranged at two right angle vertices of the tape box 132. Of course, in other embodiments, the arrangement positions of the counting tape guide 80 and the positioning block 133 are not limited.

[0126] Specifically, the tape box 132 is provided with an observation window 1323, through which the amount of the wiping tape 131 wound on the first winding member 135 and the second winding member 136 can be observed. It should be understood that in other embodiments, in order to facilitate the observation of the amount of the wiping tape 131 wound on the first winding member 135 and the second winding member 136, the entire tape box 132 can also be made of a transparent material.

[0127] The working principle of the film pushing device 100 provided in the embodiment of the present invention is as follows:

[0128] When it is necessary to flatten the blood on the slide glass 200:

[0129] The push piece 25 of the push piece mechanism 20 rotates to the push piece position relative to the mounting seat 21, and the tilt angle between the push piece 25 and the glass slide 200 is in the range of 0°-90°. When the push piece 25 contacts the glass slide 200, an interaction force is generated between the glass slide 200 and the push piece 25, and the push piece 25 transmits the force to the mounting block 24, and the mounting block 24 compresses the first elastic member 26, and the second mounting plate 212 transmits the above force to the second elastic member 29, and the second mounting plate 212 slides relative to the first mounting plate 211, and the first elastic member 26 and the second elastic member 29 are elastically deformed to ensure that the push piece 25 and the glass slide 200 are closely attached at all places.

[0130] When the fourth driving motor 321 of the slide mechanism 30 rotates forward, the driving wheel 322 is driven to rotate, the belt 323 drives the driven wheel 324 to rotate, the screw rod 325 rotates forward, the slide holder 33 drives the slide 200 to move forward in the third direction, and the pusher 25 of the slide pusher mechanism 20 pushes the blood on the slide 200 flat. Then the slide mechanism 30 returns to the origin.

[0131] When the push piece 25 needs to be wiped:

[0132] The liquid injection member 110 injects the cleaning medium onto the wiping portion 1311, and the third driving motor 130 rotates to bring the wet wiping portion 1311 to the wiping position. The push piece 25 of the push piece mechanism 20 rotates to the cleaning position relative to the mounting seat 21, and the second driving member 14 drives the wiping unit 12 to reciprocate in the second direction, and the positioning block 133 presses the wiping portion 1311 against the push piece 25 to wipe the push piece 25.

[0133] Another embodiment of the present invention further provides a film pushing mechanism 20 included in the film pushing device 100 .
