[0071] Specific combination Figure 2 and Figure 4As shown, the two support wheels 2322 are connected to the connecting member 2321 by rotating at intervals along the Z direction, and the adjusting beam 2311 passes through the two support wheels 2322, so that the connecting assembly 232 is movably connected to the adjusting beam 2311, and the connecting member 2321 is fixedly connected to the second end of the Y movable plate; with the change of the relative position of the adjusting beam 2311 in the Z direction, the Y movable plate is in a horizontal state, and when the X driving member drives the X movable plate and the Y movable plate to move along the X direction, with the rolling of the two support wheels 2322, the relative position of the connecting assembly 232 and the adjusting beam 2311 is changed, so as to ensure the movement consistency of the two ends of the Y movable plate, and further improve the operation stability and operation accuracy of the pipetting mechanism 220.

[0072] Preferably, the outer peripheral wall of the support wheel 2322 is configured as a curved surface that is recessed toward the center of the support wheel 2322 .

[0073] Specific combination Figure 4 As shown, in this embodiment, the adjusting beam 2311 is set as a cylindrical beam, and the outer peripheral walls of the two supporting wheels 2322 are set as curved surfaces that are recessed toward the center of the supporting wheels 2322. This allows the connecting component 232 to be movably connected to the adjusting beam 2311, while limiting the relative position of the adjusting beam 2311 and the connecting component 232 in the Y direction, thereby preventing the adjusting beam 2311 from detaching from between the two supporting wheels 2322, and further improving the operating stability of the pipetting mechanism 220.

[0074] In some other embodiments, the connecting assembly 232 includes a connecting sleeve, which is fixedly connected to the Y-direction moving assembly 222 and sleeved on the adjusting beam 2311. When the X-driving member drives the X-moving plate and the Y-moving plate to move along the X-direction, the connecting sleeve slides on the adjusting beam 2311, which can ensure the consistency of movement of the two ends of the Y-moving plate and prevent the adjusting beam 2311 from being separated from the connecting sleeve. Alternatively, a sliding groove is provided on the adjusting beam 2311 along the X-direction, the connecting assembly 232 is fixedly connected to the second end of the Y-moving plate, and a sliding block is provided corresponding to the sliding groove, and the sliding block is slidably connected in the sliding groove.

[0075] In some other embodiments, the connecting assembly 232 includes a gear and a rack, the rack extends along the X direction and is arranged on the adjustment beam 2311, the gear meshes with the rack, and is transmission-connected with the Y-direction moving assembly 222, and a gear driving member is correspondingly arranged on the gear. The rack is arranged on the upper end surface of the adjustment beam 2311, the gear and the rack are meshed, and the gear driving member is transmission-connected with the gear. The gear driving member operates to drive the active gear to rotate, thereby meshing with the passive gear and the rack, and the X moving plate and the Y moving plate cooperate with the X driving member along the X direction to change the relative position of the X moving plate and the Y moving plate in the X direction, thereby ensuring the consistency of movement of the two ends of the Y moving plate and improving the movement accuracy of the Y moving plate.

[0076] In the above embodiment, the corresponding connection components 232 are all provided with limit components. After the relative position of the connection component 232 and the adjustment beam 2311 is adjusted, the limit components limit the current relative position of the connection component 232 and the adjustment beam 2311 to ensure the subsequent use effect of the pipetting device 200. Specifically, the limit components can be provided with two limit buckles, and both limit buckles can be detachably connected to the adjustment beam 2311. After the relative position of the connection component 232 and the adjustment beam 2311 is adjusted, the two limit buckles are respectively provided on both sides of the connection component 232 and are both connected to the adjustment beam 2311, so as to prevent the connection component 232 from shifting along the X direction on the adjustment beam 2311.

[0077] Preferably, the pipetting device 200 further includes an intelligent control component, which includes a level sensor and a controller. The level sensor is disposed on the pipetting mechanism 220 , and the controller is connected to the level sensor and the adjustment mechanism 230 .

[0078] Specifically, the horizontal sensor is arranged on the Y movable plate, and is used to monitor the real-time horizontal state of the Y movable plate and transmit it to the controller. When the horizontal sensor detects that the Y movable plate is in a non-horizontal state, the adjustment signal is transmitted to the controller. The controller receives the adjustment signal and sends an adjustment instruction to the adjustment drive component. The adjustment drive component operates according to the received adjustment instruction to drive the adjustment member 2312 and the adjustment beam 2311 to rise and fall, so that the Y movable plate is adjusted to a horizontal state. After that, the horizontal sensor sends a stop signal to the controller, and the adjustment drive component stops operating, so that the adjustment member 2312, the adjustment beam 2311, and the Y movable plate remain in the current state. The intelligent control component can realize adaptive adjustment without manual operation, further improving the timeliness and adjustment accuracy of position adjustment.

[0079] In addition, in this embodiment, the pipetting mechanism 220 may also be connected to the controller to achieve linkage between the pipetting mechanism 220 and the adjustment mechanism 230 .

[0080] In some other embodiments, the adjustment mechanism 230 can also be configured as a telescopic support rod 233, a telescopic stopper and a plurality of adjustment slots 234. Figure 8As shown, a plurality of adjustment slots 234 are evenly spaced at the second end of the Y moving plate along the length direction of the Y moving plate (i.e., the Y direction), the first end of the telescopic support rod 233 is rotatably connected to the first end of the X moving plate, and the second end of the telescopic support rod 233 is engaged in the corresponding adjustment slot 234 according to actual needs, so that the telescopic support rod 233 supports the second end of the Y moving plate with the help of the X moving plate, so that the Y moving plate is in a horizontal state, that is, by changing the length of the telescopic support rod 233, the second end of the telescopic support rod 233 is engaged with different adjustment slots 234 to adjust the height of the second end of the Y moving plate, so that the Y moving plate is always in a horizontal state. The telescopic limiter can be a threaded connector, and a threaded hole is set on the telescopic support rod 233, and the overall length of the telescopic support rod 233 is limited or changed by screwing the threaded connector.

[0081] Alternatively, the adjustment mechanism 230 can also be configured as a telescopic support rod 233, a telescopic limiter and a sliding rod (not shown in the figure), the sliding rod is fixedly arranged at the second end of the Y movable plate and extends along the Y direction, the first end of the telescopic support rod 233 is rotatably connected to the first end of the X movable plate, the first end of the telescopic support rod 233 is fixedly provided with a sliding sleeve, the sliding sleeve is slidably connected to the sliding rod, the length of the telescopic support rod 233 is changed, and the sliding sleeve is slid on the sliding rod to adjust the height of the second end of the Y movable plate, so that the Y movable plate is always in a horizontal state, and the telescopic limiter can adopt a threaded connector or a buckle slot structure.
