[0041] The utility model provides a mechanical arm liquid transfer station 100 .

[0042] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0043] In the embodiments of the present invention, Figures 1 to 4 As shown, the robotic arm pipetting station 100 includes a base 10, a pipetting robot 20, a test tube rack 30 and a liquid supply assembly, wherein the pipetting robot 20 is used to aspirate liquid and transfer it to a test tube, and the pipetting robot 20 is arranged on the base 10; the test tube rack 30 is used to store test tubes, and the test tube rack 30 is arranged on the base 10; the liquid supply assembly is used to provide at least two reagents, and the liquid supply assembly is arranged on the base 10; the pipetting robot 20 aspirates liquid through the liquid supply assembly and transfers the reagent to the test tube.

[0044] It can be understood that the test tube rack 30 is provided with a plurality of positioning holes for placing test tubes. A plurality of test tubes to be filled with liquid are placed manually or robotically at the positions of the positioning holes. The pipetting robot 20 cooperates with the liquid supply assembly to transfer at least two reagents into the test tubes respectively. The pipetting robot 20 can achieve batch pipetting of the test tubes by walking along a specific path, thereby reducing the problem of missed liquid addition and improving the efficiency of liquid addition.

[0045] The technical solution of the utility model includes a base 10, a liquid transfer robot 20, a test tube rack 30 and a liquid supply component. The liquid transfer robot 20 realizes liquid aspiration through the liquid supply component and transfers the reagent to the test tube. Since the liquid transfer robot 20 cooperates with the liquid supply component to realize automatic liquid aspiration and automatic liquid transfer, the technical problems of low efficiency, unstable addition amount and missed addition of liquid in the manual liquid transfer in the prior art are effectively solved, thereby achieving the technical effect of improving efficiency, reducing errors and accurately adding liquid.

[0046] In the embodiments of the present invention, Figures 1 to 3 As shown, the pipetting robot 20 includes a base 21, an industrial robot 22, a chuck 23, a pipette gun 24 and a liquid outlet tube 25, wherein the base 21 is arranged on the base 10; the industrial robot 22 is arranged on the base 21; the chuck 23 is arranged at the end of the industrial robot 22; the pipette gun 24 is arranged on the chuck 23; the liquid outlet tube 25 is arranged on the chuck 23; the liquid supply component includes a first liquid supply component 40 and a second liquid supply component 50, the first liquid supply component 40 provides reagents for the pipette gun 24, and the second liquid supply component 50 provides reagents for the liquid outlet tube 25.

[0047] The base 21 of the utility model is used to fix the industrial robot 22, and is arranged on the base 10 in a detachable connection manner. During transportation, by adjusting the mechanical arm of the industrial robot 22, the mechanical arm is moved closer to the base 21 and the base 10, so that the overall volume of the liquid transfer robot 20 can be reduced. The chuck 23 of the industrial robot 22 is used to install the liquid transfer gun 24 and the liquid outlet tube 25, that is, the two reagents are transferred through two different liquid transfer components, which can avoid the problem of low precision of the added liquid caused by mixed liquid.

[0048] In the embodiments of the present invention, Figure 1 , Figure 2 and Figure 4 As shown, the first liquid supply component 40 includes a tip placement seat 41 and a reagent tank support 42, wherein the tip placement seat 41 is used to store the tip, and the tip placement seat 41 is arranged on the base 10; the reagent tank support 42 is used to place the reagent tank storing the first reagent, and the reagent tank support 42 is arranged on the base 10; the industrial robot 22 moves to the tip placement seat 41 to clamp the tip, and moves to the reagent tank support 42 to absorb the first reagent.

[0049] The first liquid supply component 40 of the utility model provides the first reagent for the pipette gun 24. Specifically, the industrial robot 22 drives the mechanical arm to rotate, so that the pipette gun 24 moves to the position of the tip placement seat 41, and the industrial robot 22 drives the pipette gun 24 to move downward and clamp the tip. Subsequently, the industrial robot 22 drives the mechanical arm to rotate, so that the pipette gun 24 moves to the position of the reagent tank support 42, and the pipette gun 24 absorbs a certain amount of the first reagent through the tip. After the absorption of the first reagent is completed, the industrial robot 22 drives the mechanical arm to rotate, so that the pipette gun 24 moves to the top of the test tube and adds the first reagent to the test tube. The tip is a disposable consumable. After completing one absorption and liquid addition, the tip is removed and discarded by manual operation or automation.

[0050] In the embodiments of the present invention, Figure 1 , Figure 2 and Figure 4 As shown, the second liquid supply component 50 includes a pump body mounting seat 51 and a peristaltic pump 52, wherein the pump body mounting seat 51 is arranged on the base 10; the peristaltic pump 52 is arranged on the pump body mounting seat 51, the liquid inlet end of the peristaltic pump 52 is connected to the second reagent, and the liquid outlet end of the peristaltic pump 52 is connected to the liquid outlet pipe 25.

[0051] The second liquid supply component 50 of the utility model provides the second reagent for the liquid outlet tube 25. Specifically, the liquid inlet end of the peristaltic pump 52 is connected to the second reagent through a hose, and the liquid outlet end of the peristaltic pump 52 is connected to the liquid outlet tube 25 through a hose. The second reagent is transported by the peristaltic pump 52. The high precision makes the second reagent added to the test tube each time the same amount is used. At the same time, the liquid outlet tube 25 and the peristaltic pump 52 are connected by a hose, that is, the second reagent is transported by the hose. The industrial robot 22 only needs to move to the test tube position where liquid needs to be added and start the peristaltic pump 52 to add liquid. The entire pipetting process is more convenient, fast, and efficient.

[0052] The first liquid supply assembly 40 and the second liquid supply assembly 50 of the utility model are independently arranged, and can be used separately or alternately according to actual needs during pipetting to meet different pipetting requirements.

[0053] In the embodiments of the present invention, Figures 1 to 3 As shown, there are two liquid outlet pipes 25 and they are spaced apart, the spacing between the two liquid outlet pipes 25 is the same as the spacing between two adjacent test tubes, and there are two peristaltic pumps 52, which are respectively connected to the two liquid outlet pipes 25. The method of using two liquid outlet pipes 25 and two peristaltic pumps 52 to jointly realize pipetting can improve the efficiency of pipetting, and the industrial robot 22 drives the mechanical arm to rotate so that the two liquid outlet pipes 25 are aligned with the two test tubes to be filled with liquid up and down, and the two peristaltic pumps 52 are started respectively to realize simultaneous filling.

[0054] In the present utility model, if Figure 1 , Figure 2 and Figure 4 As shown, the pump body mounting seat 51 is also provided with a protective cover 53, and a closed mounting cavity is formed between the pump body mounting seat 51 and the protective cover 53, which partially shields the peristaltic pump 52 and plays a protective role.

[0055] In the embodiments of the present invention, Figure 1 and Figure 2 As shown, the robot arm pipetting station 100 also includes a buckle rod 60 for moving the tip stripping buckle of the pipette gun 24 . The buckle rod 60 is detachably disposed on the outer side of the pump body mounting seat 51 .

[0056] It can be understood that the pipette tip is a disposable consumable. After the reagent is absorbed and the pipetting is completed, the pipette tip needs to be replaced for the next pipetting. The pipette gun 24 is provided with a tip stripping buckle. When the tip stripping buckle is turned, the pipette tip will be pushed and detached from the pipette gun 24. The utility model is provided with a buckle rod 60 for turning the tip stripping buckle. The buckle rod 60 is L-shaped. When the tip needs to be replaced, the industrial robot 22 drives the pipette to move to the position of the buckle rod 60, so that the tip stripping buckle is located below the buckle rod 60. Then, the industrial robot 22 drives the pipette gun 24 to move upward, that is, the tip stripping buckle moves in the direction close to the buckle rod 60. The buckle rod 60 contacts and turns the tip stripping buckle, so that the tip falls off the pipette gun 24. In this way, the automatic shedding of the tip can be achieved without manual operation, which is more convenient and quick.

[0057] In the embodiments of the present invention, Figure 2 As shown, the buckle rod 60 is connected to the pump body mounting seat 51 through a quick locking knob 61. The quick locking knob 61 can be used to quickly assemble the buckle rod 60. At the same time, during transportation, the quick locking knob 61 can be loosened and the buckle rod 60 can be rotated toward the base 10, so that the buckle rod 60 is close to the side of the pump body mounting seat 51, reducing the height of the buckle rod 60 and making the overall structure compact.

[0058] In the embodiments of the present invention, Figure 2 and Figure 4 As shown, the robot arm pipetting station 100 also includes a waste box 70, which is arranged on the base 10 and is located below the buckle rod 60. The waste box 70 is used to recycle waste gas suction tips. The setting position of the waste box 70 is specifically located below the buckle rod 60. When the buckle rod 60 moves the suction tip stripping buckle, the suction tip falls vertically to the waste box 70 below for recycling.

[0059] In the embodiment of the present invention, the pipette tip placement seat 41, the reagent tank support 42 and the waste box 70 are all arranged on the base 10 through a detachable bottom plate.

[0060] The tip placement seat 41, reagent tank support 42 and waste box 70 of the utility model form a module structure through the bottom plate, and then the module structure is installed at the corresponding position of the base 10. In this way, the robot arm pipetting station 100 can be quickly disassembled and adjusted in position, and the bottom plate and the base 10 are fixed by threaded fasteners.

[0061] The above description is only an optional embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
