It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the present invention are shown in the accompanying drawings, not all of them.

[0035] In medical testing, cell samples typically require slide preparation and staining for better observation. To automate cell slide preparation while ensuring accurate pipetting and optimal slide quality, [further steps are needed]. Figures 1-4 As shown, the present invention provides an automated liquid-based cell slide preparation machine. The automated liquid-based cell slide preparation machine includes a frame 1, a transport assembly 2, an electric gripper assembly 24, a vibrator 4, a clamping device 7, a centrifuge 6, a pipetting assembly 3, and a slide preparation chamber assembly 8.
[0036] The machine includes a frame 1 with a worktable 11; a transport assembly 2 mounted on the worktable 11 and capable of moving in three-dimensional space; an electric gripper assembly 24 mounted on the transport assembly 2; a shaker 4 mounted on the worktable 11 for shaking sample vials 41; a clamping device 7 fixedly mounted on the worktable 11 for clamping sample vials 41, and the electric gripper assembly 24 for removing the caps from sample vials 41; a centrifuge 6 mounted on the worktable 11, and a slide preparation chamber assembly 9 mounted on the centrifuge 6; a pipetting assembly 3 mounted on the transport assembly 2 for transferring liquid from sample vials 41 into slide preparation chamber assembly 9; and a slide removal assembly 8 mounted on the worktable 11, where the centrifuged slide preparation chamber assembly 9 is fixed and the slide removal assembly 8 can empty the liquid from the slide preparation chamber assembly 9, and the electric gripper assembly 24 can remove the slides from the slide preparation chamber assembly 9.
[0037] After the sample vial 41 is vibrated on the shaker 4, the transport assembly 2 uses the electric gripper assembly 24 to transfer the sample vial 41 to the clamping device 7 for clamping. Then, the electric gripper assembly 24 removes the cap, and the pipetting assembly 3 transfers the liquid from the sample vial 41 into the slide preparation chamber assembly 9 placed in the centrifuge 6. The centrifuge 6 starts centrifugation. After the liquid has been centrifuged, the electric gripper assembly 24 picks up the slide preparation chamber assembly 9 and moves it to the slide preparation chamber assembly 8 via the transport assembly 2. The slide preparation chamber assembly 8 pours out the liquid from the slide preparation chamber assembly 9, and then the electric gripper assembly 24 removes the slide and places it into the material box. In this process, the slide preparation work is automated, and the use of the pipetting assembly 3 for automated pipetting ensures accurate pipetting volume and guarantees the slide preparation effect.
[0038] Furthermore, the handling assembly 2 is a three-axis motion structure, including a first motion module 21, a second motion module 22, and a third motion module 23. The first motion module 21 is mounted on the worktable 11, and the second motion module 22 is mounted on the first motion module 21, with the second motion module 22 being driveably connected to the first motion module 21. The first motion module 21 can drive the second motion module 22 to move along the X-axis. The third motion module 23 is mounted on the second motion module 22, with the third motion module 23 being driveably connected to the second motion module 22, with the second motion module 22 driving the third motion module 23 to move along the Y-axis. An electric gripper assembly 24 is mounted on the third motion module 23, and the electric gripper assembly 24 is driveably connected to the third motion module 23, with the third motion module 23 driving the electric gripper assembly 24 to move vertically along the Z-axis. Through the above configuration, the handling assembly 2 can drive the electric gripper assembly 24 to achieve three-dimensional spatial movement.
[0039] Furthermore, the electric gripper assembly 24 includes a first motor, a second motor, and a first gripper assembly 25. The first motor is mounted on the third motion module 23 of the conveying assembly 2. The first motor is driveably connected to the second motor, and the second motor is driveably connected to the first gripper assembly 25. The first motor can drive the first gripper assembly 25 to rotate via the second motor, and the second motor can drive the first gripper assembly 25 to perform opening or clamping actions. Specifically, the first gripper assembly 25 includes a first clamping member, a second clamping member, a first gear, a first rack, and a second rack. The first rack is connected to the first clamping member, the second rack is connected to the second clamping member, the first gear meshes with the first rack and the second rack, and the first gear is connected to the output shaft of the second motor. The second motor can drive the first gear to rotate, thereby enabling the first clamping member and the second clamping member to move closer or further apart. The first motor can drive the first gripper assembly 25 to rotate via the second motor, realizing a twisting action. By using motor transmission, the transmission accuracy can be guaranteed. In other embodiments, a lead screw and nut structure can be used instead of a gear and rack structure, and no further restrictions are imposed here.
[0040] Furthermore, the clamping device 7 includes a first cylinder 71 and a clamping claw 72. The first cylinder 71 is fixedly mounted on the worktable 11, and the clamping claw 72 is connected to the piston rod of the first cylinder 71. The first cylinder 71 can drive the clamping claw 72 to perform clamping or releasing actions. By driving the clamping claw 72 with the first cylinder 71, the sampling bottle can be clamped or released.
[0041] Furthermore, the pipetting assembly 3 includes a pump assembly and a liquid-taking assembly. The pump assembly is fixedly mounted on the worktable 11 and is connected to the liquid-taking assembly. The liquid-taking assembly is mounted on the third motion module 23 of the transport assembly 2. The pump assembly can transfer the sample in the sample bottle 41 to the slide preparation chamber assembly 9 through the liquid-taking assembly, and add buffer solution to the slide preparation chamber assembly 9. Through the above settings, automated transfer of sample liquid can be achieved, and by controlling the pump assembly, accurate pipetting volume can be ensured.
[0042] Furthermore, the pump assembly includes a suction pump 31 and an injection pump 32. The liquid extraction assembly includes a pipette 33, a first conduit, and a second conduit. The pipette 33 is mounted on the transport assembly 2, and the first and second conduits are disposed within the pipette 33. One end of the first conduit is connected to the suction pump 31, and one end of the second conduit is connected to the injection pump 32. The suction pump 31 transfers the sample to the slide preparation chamber assembly 9 via the first conduit, and the injection pump 32 injects the buffer solution into the corresponding slide preparation chamber assembly 9. This method enables sample transfer.
[0043] Furthermore, the transport assembly 2 is equipped with a lifting assembly, which is connected to the pipette 33 for transmission. The lifting assembly can drive the pipette 33 to move vertically. By setting up the lifting assembly, the pipette 33 can be moved, thereby further expanding the lifting range of the pipette 33 to meet the requirements of pipetting. Specifically, in this embodiment, a pulley motor 34 is fixedly installed on the transport assembly 2. The pulley motor 34 drives the belt 35 transmission assembly to move. The pipette 33 is connected to the belt 35 in the belt 35 transmission assembly. The lifting movement of the pipette 33 is achieved by the pulley motor 34 driving the belt 35. In other embodiments, a lifting cylinder can also be used, and the piston rod of the lifting cylinder can drive the pipette 33 to move. No further restrictions are placed on the lifting assembly here.
[0044] Furthermore, the automated liquid-based cell slide preparation machine also includes a guiding assembly, which comprises a slide rail, a slider, and a guide block 36. The slide rail is fixedly mounted on the transport assembly 2, the slider is slidably mounted on the slide rail, and the pipette 33 passes through the guide block 36 and is connected to the slider. By setting up the guiding assembly, the movement of the pipette 33 can be guided, thereby ensuring the smoothness and accuracy of the movement of the pipette 33 and enabling the successful completion of pipetting operations.
[0045] Furthermore, the automated liquid-based cell slide preparation machine also includes a support 5, on which a pipette tip 51 is mounted. A pipette 33 can be inserted into the pipette tip 51 and move the pipette tip 51. Specifically, during each pipetting process, the pipette 33 inserts a disposable pipette tip 51, the aspiration pump 31 draws sample liquid into the pipette tip 51 through a first conduit, and then pipettes it into the slide preparation chamber assembly 9. The injection pump 32 injects buffer solution through a second conduit, and the lifting assembly moves the pipette 33 upward, causing the pipette tip 51 to collide with the guide block 36 and detach.
[0046] Further, the slide preparation chamber assembly 8 includes a rotary motor 81, a drive motor 82, and a second gripper assembly. The rotary motor 81 is mounted on the worktable 11 and is driven by the drive motor 82. The drive motor 82 is also driven by the second gripper assembly. The rotary motor 81 can drive the second gripper assembly to rotate via the drive motor 82, and the drive motor 82 can drive the second gripper assembly to open or clamp. Specifically, the slide preparation chamber assembly 9 includes a tray 92, a glass slide, and a glue tube 91. The glass slide is fixed to the tray 92 via the glue tube 91, which is threadedly connected to the tray 92. After centrifugation, the electric gripper assembly 24 transports the slide preparation chamber assembly 9 to the second gripper assembly via the transport assembly 2. The second gripper assembly clamps the tray 92 under the drive of the drive motor 82. Then, the rotary motor 81 drives the second gripper assembly to rotate, emptying the liquid in the glue tube 91. Finally, the electric gripper assembly 24 unscrews the glue tube 91 and grips the glass slide. In this embodiment, the second gripper assembly has the same structure as the first gripper assembly 25, and will not be described in detail here.
[0047] Furthermore, in order to ensure the cleanliness of the slide preparation chamber assembly 9 and avoid residual sample liquid on the slide, the pump assembly also includes a cleaning pump. A third conduit is provided in the pipette 33, and the cleaning pump is connected to the third conduit. After the liquid in the glue cartridge 91 is poured out, the cleaning pump injects clean water into the glue cartridge 91 through the third conduit for cleaning, and then pours it out, thereby ensuring the cleanliness of the slide.
[0048] Furthermore, a waste inlet is provided on the workbench 11, and a waste bin 12 connected to the waste inlet is provided on the frame 1. Specifically, the waste inlet is directly opposite the second gripper assembly, which facilitates the pouring of waste liquid and the recycling of disposable pipette tips 51.
[0049] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
