It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0038] When the embodiments of the present invention mention ordinal numbers such as "first" and "second", unless they do express the meaning of order according to the context, they should be understood as being merely for the purpose of distinction.

[0039] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0040] Specific embodiments, such as Figure 1-4The sampling mechanism for a contamination-proof protein analyzer shown in the figure includes: a sampling bracket 21; a sampling mounting plate 22, which is movably arranged on the sampling bracket 21; a first sampling drive mechanism 23, which is used to drive the sampling mounting plate 22 to move horizontally along the X-axis direction; a second sampling drive mechanism 24, which is used to drive the sampling mounting plate 22 to move horizontally along the Y-axis direction; a sampling mechanism 25, which is movably arranged on the sampling mounting plate 22, and the sampling mechanism 25 includes a sampling needle 251; a third sampling drive mechanism 26, which is used to drive the sampling mechanism 25 to move up and down along the Z-axis direction; an anti-fouling cover 27, which is arranged on the sampling mounting plate 22 and covers the sampling mechanism 25 and the third sampling drive mechanism 26, and the third sampling drive mechanism 26 can drive the sampling needle 251 to move up and down along the Z-axis direction to extend out of the anti-fouling cover 27 or retract into the anti-fouling cover 27. During use, the first sampling drive mechanism, the second sampling drive mechanism and the third sampling drive mechanism cooperate to drive the sampling mechanism to move up and down and laterally, so that the sampling needle moves to the sampling position for sampling. In addition, by arranging an anti-fouling cover to cover the sampling mechanism and the third sampling drive mechanism, the sampling mechanism and the third sampling drive mechanism can be protected, thereby reducing contamination or damage to the sampling mechanism.

[0041] Specifically, the anti-pollution cover 27 is mounted on the sampling mounting plate 22, and the edge of the anti-pollution cover 27 is provided with a plurality of cover connection holes 281 and cover connection bolts 282 that pass through the cover connection holes 281 to connect the anti-pollution cover 27 to the sampling mounting plate 22. The anti-pollution cover 27 is detachably mounted on the sampling mounting plate 22 through the cover connection bolts 282 and the cover connection holes 281. The plurality of cover connection holes 281 are arranged along the circumference of the anti-pollution cover 27 along the edge of the anti-pollution cover 27, providing a more stable connection.

[0042] In addition, the sampling mounting plate 22 is provided with a stirring mechanism 29 and a stirring drive mechanism 210 for driving the stirring mechanism 29 to move up and down along the Z-axis. The stirring mechanism 29 includes a stirring mounting member 291, a stirring rod 292 rotatably mounted on the stirring mounting member 291, and a stirring drive member 293 mounted on the stirring mounting member 291 for driving the stirring rod 292 to rotate. The anti-fouling cover 27 covers the stirring mechanism 29 and the stirring drive mechanism 210, and the stirring drive mechanism 210 can drive the stirring rod 292 to move up and down along the Z-axis to extend out of the anti-fouling cover 27 or retract into the anti-fouling cover 27. The anti-fouling cover 27 is provided with a first cover body clearance hole 271 and a second cover body clearance hole 272 for respectively passing the sampling needle 251 and the stirring rod 292. The stirring mechanism 29 can simultaneously achieve the stirring function, making it more convenient to use, more efficient, and smaller in overall size. The first cover body clearance hole 271 and the second cover body clearance hole 272 are provided so that the sampling mechanism 25 and the stirring mechanism 29 can work normally under the premise of being protected by the anti-fouling cover 27. The stirring driving member 293 can be driven by a rotary motor.

[0043] Furthermore, the sampling mechanism 25 also includes a sampling mounting member 252, a mounting needle sleeve 253 mounted on the sampling mounting member 252, a needle tube 254 inserted through the mounting needle sleeve 253, and a sampling needle connector 255 sleeved on one end of the sampling needle 251. The sampling needle 251 is inserted into the needle tube 254. The sampling mechanism 25 also includes a liquid level detection device 256 electrically connected to the sampling needle 251 for detecting whether the sampling needle 251 contacts the reagent liquid. The sampling needle connector 255 is connected to a negative pressure device, so that the sampling needle generates negative pressure to absorb the reagent liquid.

[0044] More specifically, the liquid level detection device 256 includes a detection mounting plate 2561 mounted on one side of the sampling mounting member 252, a detection circuit board 2562 mounted within the detection mounting plate 2561, a detection end plate 2563 electrically connected to the sampling needle 251 at one end and to the detection circuit board 2562 at the other end, and a shielding cover 2564 covering the detection mounting plate 2561. When the sampling end of the sampling needle contacts the reagent solution and moves only 2-3 mm below the liquid surface, a change in capacitance occurs. The detection end plate transmits a capacitance change signal to the detection circuit board, which in turn drives the third sampling drive mechanism to stop driving the sampling mechanism downward in the Z-axis direction, preventing the sampling needle from being immersed in the reagent solution over a large area and potentially contaminating it. The shielding cover 2564 also protects the detection circuit board 2562.

[0045] Furthermore, in order to make it safer to use, the sampling mechanism 25 also includes an insulating sleeve 257 which is sleeved between the sampling needle 251 and the needle tube 254 .

[0046] Furthermore, a drag chain mounting member 211 is provided on the sampling mounting plate 22, located between the sampling mechanism 25 and the stirring mechanism 29. A first drag chain 212 is provided between the drag chain mounting member 211 and the sampling mechanism 25, and a second drag chain 213 is provided between the drag chain mounting member 211 and the stirring mechanism 29. This keeps the wiring within the prescribed path, preventing cross-entanglement and entanglement, thereby maintaining the normal operation of the equipment. Furthermore, the drag chain design prevents foreign matter from entering the equipment, thereby improving the safety of the mechanical equipment. By reducing wiring damage and failure, the drag chain can extend the service life of the equipment and reduce maintenance and replacement costs.

[0047] Specifically, the first sampling drive mechanism 23 includes a first sampling drive guide post 231, which is horizontally mounted on the sampling support 21 along the X-axis; a first sampling drive guide sleeve 232, which is sleeved on the first sampling drive guide post 231; a first sampling drive mounting member 233, which is connected to the first sampling drive guide sleeve 232 and on which the sampling mounting plate 22 is movably mounted; and a first sampling drive member 234, which is mounted on the sampling support 21 and is used to drive the first sampling drive mounting member 233 to move along the X-axis. The first sampling drive member 234 can be driven by a telescopic cylinder or by a motor-driven conveyor line for reciprocating movement.

[0048] More specifically, the second sampling drive mechanism 24 includes a second sampling drive guide post 241, which is horizontally mounted on the first sampling drive mounting member 233 along the Y-axis; a second sampling drive guide sleeve 242, which is sleeved on the second sampling drive guide post 241 and connected to the sampling mounting plate 22; and a second sampling drive member 243, which is mounted on the first sampling drive mounting member 233 and is used to drive the sampling mounting plate 22 along the Y-axis. The second sampling drive member 243 can be driven by a telescopic cylinder or by a motor-driven conveyor line for reciprocating movement.

[0049] Furthermore, the third sampling drive mechanism 26 includes a third sampling drive guide post 261 vertically mounted on the sampling mounting plate 22 along the Z-axis. The sampling mounting member 252 is movably mounted on the third sampling drive guide post 261. The third sampling drive mechanism 26 also includes a third sampling drive member 262 for driving the sampling mounting member 252. The third sampling drive member 262 can be driven by a telescopic cylinder or a motor-driven conveyor line for reciprocating movement. Similarly, the stirring drive mechanism 210 has the same structure as the third sampling drive mechanism 26 to drive the stirring mechanism 29 to move up and down along the Z-axis.

[0050] The above is an implementation method provided in conjunction with specific content, and does not necessarily mean that the specific implementation of this utility model is limited to these descriptions. At the same time, due to differences in industry nomenclature, it is not limited to the above nomenclature, nor is it limited to English nomenclature. Any method, structure, etc. similar to or identical to the method, structure, etc. of this utility model, or any technical deduction or replacement based on the concept of this utility model, shall be considered within the scope of protection of this utility model.
