DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The principles and features of the present utility model will be described below in conjunction with the accompanying drawings. The examples given are only used to explain the present utility model and are not intended to limit the scope of the present utility model.

[0023] It should be noted that unless otherwise clearly defined and limited, the terms "installation", "connection", and "linkage" in the terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrally formed structure. For those of ordinary skill in the art, the specific meanings of such terms in this patent can be understood according to specific circumstances.

[0024] As Figure 1 , 5 As shown, the overall structure of the full-automatic centrifugal slide-making machine generally includes a preservation liquid bottle conveying mechanism 1, a preservation liquid suction mechanism 4, a preservation liquid bottle cap opening and closing mechanism 3, and a slide-making chamber centrifugal mechanism 2.

[0025] The preservation liquid bottle conveying mechanism 1 includes a specimen turntable 1.1, preservation liquid bottle placement holes 1.2 provided on the specimen turntable 1.1. The preservation liquid bottles 5 are placed in the preservation liquid bottle placement holes 1.2, and straw placement holes 1.3 are also provided on the specimen turntable 1.1. A plurality of uniformly distributed preservation liquid bottle placement holes 1.2 are provided on the surface of the specimen turntable 1.1, and the preservation liquid bottle placement holes 1.2 correspond to the straw placement holes 1.3 one by one; the slide-making chamber centrifugal mechanism 2 includes a centrifugal turntable 2.1, and a plurality of uniformly distributed slide-making chamber mounting seats 2.2 for assembling the slide-making chambers are provided on the surface of the centrifugal turntable 2.1.

[0026] A preservation liquid bottle cap opening and closing mechanism 3 is provided above and below the specimen turntable 1.1 to open the caps of the preservation liquid bottles. After the preservation liquid suction mechanism 4 uses the straws in the straw placement holes 1.3 to suck the liquid in the preservation liquid bottles 5, the caps of the preservation liquid bottles 5 are covered. After the preservation liquid suction mechanism 4 sucks the specimen liquid in the preservation liquid bottles and rotates in a direction, it injects the liquid into the slide-making chambers in the slide-making chamber mounting seats 2.2 of the slide-making chamber centrifugal mechanism 2. The centrifugal turntable 2.1 rotates centrifugally to make the slide-making chambers obtain a centrifugal acceleration, so that the cells in the specimen liquid adhere to the glass slides.

[0027] During operation, by controlling the specimen turntable to rotate a certain angle, it can be ensured that the preservation liquid bottles 5 in the corresponding preservation liquid bottle placement holes 1.2 enter below the preservation liquid bottle cap opening and closing mechanism 3, so as to sequentially extract the preservation liquid in multiple preservation liquid bottles 5, and each preservation liquid bottle 5 corresponds to a disposable straw in a straw placement hole 1.3, avoiding interference between specimens.

[0028] As Figure 2As shown in the figure, the preservation liquid bottle 5 of the present utility model includes a specimen bottle 5.1. An outwardly protruding ring platform 5.3 is formed on the upper part of the specimen bottle 5.1. When the specimen bottle 5.1 is inserted into the preservation liquid bottle placement hole 1.2, it can be placed on the preservation liquid bottle placement hole 1.2 through the ring platform 5.3. The bottom of the specimen bottle 5.1 is recessed and a limiting rib 5.4 is provided radially. It also includes a bottle cap 5.2 arranged on the ring platform 5.3.

[0029] For the preservation liquid bottle switch cover mechanism 3 among them, the present utility model provides the following three implementation manners.

[0030] Embodiment 1

[0031] As Figure 3 shown in the figure, in this embodiment, the preservation liquid bottle switch cover mechanism 3 includes an opener 3.1 arranged on a frame (not shown), a pushing bottle mechanism moving assembly 3.3, and a pushing bottle mechanism 3.2 arranged on the pushing bottle mechanism moving assembly 3.3. The opener 3.1 and the pushing bottle mechanism 3.2 are respectively located directly above and directly below one of the preservation liquid bottles 5. The pushing bottle mechanism moving assembly 3.3 can drive the pushing bottle mechanism 3.2 to approach the opener 3.1, so that the opener 3.1 fixes the bottle cap 5.2, and the pushing bottle mechanism 3.2 screws the specimen bottle 5.1, so that the bottle cap 5.2 and the specimen bottle 5.1 are closed or opened, realizing the automatic opening and closing function of the preservation liquid bottle 5.

[0032] The pushing bottle mechanism moving assembly 3.3 includes a guide rail 3.31 vertically arranged on the frame, a first slider 3.32 arranged at the upper end of the guide rail 3.31, a second slider 3.33 arranged at the lower end. A mounting plate four 3.35 is horizontally fixed at the lower end of the second slider 3.33. A mounting plate three 3.34 is horizontally fixed at the lower end of the first slider 3.32, and a mounting plate two 3.38 is horizontally fixed at the upper end. The mounting plate four 3.35 and the mounting plate three 3.34 are connected by a compression spring 3.37. A guide shaft 3.36 is also vertically arranged between the mounting plate four 3.35 and the mounting plate three 3.34, and the compression spring 3.37 is sleeved on the guide shaft 3.36.

[0033] The pushing bottle mechanism 3.2 is arranged on the mounting plate two 3.38. Specifically, the pushing bottle mechanism 3.2 includes a first motor 3.26 arranged on the mounting plate two 3.38, and a pushing bottle shaft 3.21 fixed on the motor shaft of the first motor 3.26. Two upright columns 3.28 are symmetrically arranged on the pushing bottle shaft 3.21.

[0034] The opener 3.1 includes an opening seat 3.11 arranged on a mounting plate one 3.14 for fixing the bottle cap. The mounting plate one 3.14 is arranged on the frame. A central hole is opened in the center of the opening seat 3.11. A push cover shaft 3.12 is arranged in the central hole. A power push rod 3.13 for pushing the push cover shaft 3.12 to move downward is also arranged above the push cover shaft 3.12.

[0035] When opening the cover (the bottle cover 5.2 of the preservation liquid bottle 5 is originally covered on the specimen bottle 5.1), the bottle pushing mechanism moving component 3.3 moves upward under the action of external power, and the two columns 3.28 move upward, and the starter motor 3.26 rotates slowly counterclockwise, driving the two columns 3.28 on the bottle pushing shaft 3.21 to rotate slowly, and the two columns 3.28 are inserted into the bottom of the specimen bottle 5.1 and act on the limiting rib 5.4, thereby pushing the specimen bottle 5.1 to rotate, and the bottle pushing mechanism 3.2 continues to move upward under the continued push of the bottle pushing mechanism moving component 3.3, so that the bottle cover 5.1 is opened. 2 is inserted into the cover opening seat 3.11. Since the cover opening seat 3.11 is embedded with an elastic rubber ring that is adapted to the size of the bottle cap, the bottle cap 5.2 is stuck by the cover opening seat 3.11 after being inserted into the cover opening seat 3.11. The motor 1 3.26 continues to rotate counterclockwise to drive the specimen bottle 5.1 to continue to rotate counterclockwise, while the bottle cap 5.2 is fixed. Since the pressure spring 3.37 can be compressed and deformed, the specimen bottle 5.1 can move downward and separate from the bottle cap 5.2. The slider 1 3.32 and the slider 2 3.33 move downward and reset under the drive of external power, and the motor 1 is turned off. It is explained that when the two columns 3.28 rise and just hit the limit rib 5.4, due to the rotation of the motor 1 3.26, the two columns 3.28 will immediately stagger with the limit rib 5.4 and insert into the bottom recessed area of ​​the specimen bottle 5.1, and act on the limit rib 5.4 when the motor 1 continues to rotate.

[0036] After the lid is opened, the preservation liquid aspirating mechanism 4 grabs the disposable pipette in the pipette placement hole 1.3 on the specimen turntable 1.1, absorbs the specimen liquid in the specimen bottle 5.1 and then moves away, the motor 1 is started to rotate clockwise, and the bottle pushing mechanism moving component 3.3 moves upward under the action of external power. As when opening the lid, the two columns 3.28 are inserted into the bottom of the specimen bottle 5.1 and act on the limiting rib 5.4, and then the ring table enters the bottle cap and rotates clockwise to close the lid, the motor 1 is turned off, and the bottle pushing mechanism moving component 3.3 moves downward under the action of external power. Finally, under the push of the power push rod 3.13, the bottle cap 5.2 is pushed out of the lid opening seat 3.11 by the push cover shaft 3.12.

[0037] As an implementation mode, the cover opening seat 3.11 is provided with an inner cavity with a trapezoidal cross-section for the bottle cap 5.2 to be inserted, the upper diameter of the trapezoidal inner cavity is smaller than the diameter of the bottle cap 5.2, and the lower diameter of the trapezoidal inner cavity is larger than the diameter of the bottle cap 5.2, to ensure that when the cover opener 3.1 presses the bottle cap 5.2, the bottle cap 5.2 can be in close contact with the cover opening seat 3.11, so as to ensure that the bottle cap 5.2 will not fall off after being stuck in the cover opening seat 3.11.

[0038] Embodiment 2

[0039] like Figure 4As shown in the figure, in this embodiment, the switch cover mechanism 3 of the preservation solution bottle includes an opener 3.1, a bottle pushing mechanism 3.2, and a bottle pushing mechanism moving component 3.3.

[0040] The bottle pushing mechanism moving component 3.3 is the same as that in the first embodiment. The bottle pushing mechanism 3.2 includes a first motor 3.26 arranged on the second mounting plate 3.38. A motor shaft 3.27 is arranged on the first motor 3.26. A stepped shaft 3.22 is fixedly connected to the motor shaft. A bottle pushing shaft 3.21 is sleeved on the stepped shaft 3.22. Two upright columns 3.28 are symmetrically arranged on the bottle pushing shaft 3.21. A swing rod 3.24 is also fixedly connected to the bottle pushing shaft 3.21. Two limit columns 3.25 are arranged on both sides of the stepped shaft 3.22 on the second mounting plate 3.38. The bottle pushing shaft 3.21 is seated on the stepped shaft 3.22. The stepped shaft 3.22 drives the bottle pushing shaft 3.21 only through the frictional force between the bottle pushing shaft 3.21 and the stepped shaft 3.22, and its fit tolerance is tolerance fits with medium clearance such as H6 / f5 F6 / h5, H7 / f7 F7 / h6, H8 / f7 F8 / h7, H8 / f8 F8 / h8, H9 / f9 F9 / h9, etc.

[0041] The opener 3.1 includes an opener seat 3.11 that can be rotatably arranged on the first mounting plate 3.14 through an opener bearing 3.15 for fixing the bottle cap. An opener wheel 3.16 for driving the opener seat 3.11 to rotate is also arranged. A push cover shaft 3.12 is arranged at the center of the opener seat 3.11. A power push rod 3.13 for pushing the push cover shaft 3.12 to move downward is also arranged. The opener wheel 3.16 is coaxially arranged with the opener seat 3.11, and it also includes an opener wheel motor for driving the opener wheel 3.16, which is not shown in the figure.

[0042] When opening the bottle cap, different from the first embodiment, the rotation of the first motor 3.26 is only used to eliminate the situation where the two upright columns 3.28 top against the limit ribs 5.4. After the bottle cap 5.2 enters the opener seat 3.11, the opener wheel 3.16 is started to rotate counterclockwise to unscrew the bottle cap 5.2. Under the action of the limit columns 3.25, the specimen bottle 5.1 is fixed at the limit columns 3.25 by the two upright columns 3.28, realizing the separation of the bottle cap 5.1 and the specimen bottle 5.1. After the separation is completed, the motor 3.26 rotates in the reverse direction, and the bottle pushing shaft 3.21 and the stepped shaft 3.22 return to the starting position. When closing the bottle cap, start the opener wheel 3.16 to rotate clockwise to screw the bottle cap 5.2.

[0043] Embodiment Three

[0044] As Figure 5As shown in the figure, the liquid storage bottle switch cover mechanism 3 in this embodiment includes an opener 3.1, a bottle pushing mechanism 3.2, and a bottle pushing mechanism moving component 3.3. Compared with the second embodiment, the opener 3.1 and the bottle pushing mechanism moving component 3.3 are the same, and the bottle pushing mechanism 3.2 is slightly different. The bottle pushing mechanism 3.2 in this embodiment uses a push rod type electromagnet 3.23 to replace the first motor 3.26 in the second embodiment. Specifically, the bottle pushing mechanism 3.2 in this embodiment includes a stepped shaft 3.22 fixedly arranged on 3.38. A bottle pushing shaft 3.21 is sleeved on the stepped shaft 3.22. Two columns 3.28 are symmetrically arranged at the top of the bottle pushing shaft 3.21. A swing rod 3.24 is fixedly connected to the bottle pushing shaft 3.21. A push rod type electromagnet 3.23 and two limit columns 3.25 are also arranged on 3.38. The telescopic end of the push rod type electromagnet 3.23 can push the swing rod 3.24 to rotate. The two limit columns are used to block the rotation limit of the swing rod 3.24. Of course, a return spring is also arranged between the bottle pushing shaft 3.21 and the stepped shaft 3.22 (the return spring is in the shaft hole of the bottle pushing shaft 3.21 and is not shown).

[0045] When opening the bottle, compared with the second embodiment, the electromagnet 3.23 replaces the first motor 3.26 in the second embodiment to eliminate the situation where the two columns 3.28 top against the limit ribs 5.4, and the rest is the same as the second embodiment.
