[0034] This embodiment provides an automatic device for sustainable multi-sample liquid separation. Specifically, as Figure 1 shown, it includes a sample loading module, a liquid separation module, and a control system 12.

[0035] The sample loading module includes a lifting table 1, an intelligent robotic arm 2, sample bottles 3, and a movable sample bottle tray 4. The lifting table 1 can move left and right and up and down. The intelligent robotic arm 2 is connected to the lifting table 1 and adjusts its position through the lifting table 1, and it can open and close the lids of the sample bottles 3.

[0036] The movable sample bottle tray 4 is located below the lifting table 1 and the intelligent robotic arm 2 and is used to place the sample bottles 3. The movable sample bottle tray 4 can hold six sample bottles 3 (3*2) at the same time, and the diameter of the sample bottle 3 is 70 mm. The base of the movable sample bottle tray 4 is configured with a first servo motor 10 and a mechanical eccentric device 11. Among them, the first servo motor 10 and the mechanical eccentric device 11 are used to control the rotation of the movable sample bottle tray 4 and shake the samples in the sample bottles 3.

[0037] The liquid separation module includes liquid separation tubes (a first liquid separation tube 51 and a second liquid separation tube 52), and a movable sample cup tray 6. The liquid separation tubes separate the liquid through a precision metering pump. The first liquid separation tube 51 is divided into six channels, supporting simultaneous liquid separation for six sample bottles 3, and the first liquid separation tube 51 is connected to the lifting table 1, and the lifting table 1 adjusts the position of the first liquid separation tube 51. The second liquid separation tube 52 is configured with a motor, and under the drive of the motor, the second liquid separation tube 52 moves left and right.

[0038] The liquid separation module is equipped with two movable sample cup trays 6. Each movable sample cup tray 6 is a 3*6 hole tray and can hold 18 sample cups. During liquid separation, the second liquid separation tube 52 moves to directly above the sample cup 7 for liquid separation.

[0039] The control system 12 is used to send liquid separation instructions to the sample loading module and the liquid separation module.

[0040] In addition, the automatic device for sustainable multi-sample liquid separation can also be connected to an AGV device. The AGV device picks up and places the sample bottle tray 4 and the movable sample cup tray 6 along a fixed indoor path. The movable sample bottle tray 4 is also configured with a first jack 8, and the first jack 8 can be connected to the robotic arm of the AGV device. There is a mechanical gripper on the robotic arm, and the mechanical gripper inserts into the first jack 8 to lift the movable sample bottle tray 4 to a preset fixed position. The movable sample cup tray 6 is configured with a second jack 9. Preferably, the mechanical gripper can also insert into the second jack 9 to lift the movable sample cup tray 6 to a preset fixed position.

[0041] Usage method:

[0042] After the automatic device for sustainable multi-sample liquid separation in this embodiment receives the instruction from the control system 12, it performs an automatic liquid separation operation:

[0043] The lifting platform 1 is lifted to a suitable position above the sample bottle 3, so that the intelligent robotic arm 2 is directly above the sample bottle 3. The movable sample bottle tray 4 shakes and mixes the sample bottle 3 under the drive of the first servo motor 10 and the mechanical eccentric device 11. After the liquid sample in the sample bottle 3 is mixed evenly, the intelligent robotic arm 2 opens the cap of the sample bottle 3.

[0044] Before the liquid separation starts after the cap is opened, the first liquid separation tube 51 adjusts its position through the lifting platform 1 to be directly above the sample bottle 3, and then the first liquid separation pipeline 51 pumps a part of the sample for rinsing.

[0045] After the rinsing is completed and the liquid separation starts, the first liquid separation tube 51 automatically quantitatively transfers a specified volume of sample from the sample bottle 3; at the same time, the second liquid separation tube 52 moves to directly above the specified sample cup 7 under the drive of the motor, and the specified volume of sample pumped by the first liquid separation tube 51 is transferred to the specified sample cup 7 through the second liquid separation tube 52.

[0046] After the liquid separation is completed, the intelligent robotic arm 2 closes the cap of the sample bottle 3. At the same time, after the liquid separation is over, the automatic device for sustainable multi-sample liquid separation in this embodiment will automatically empty the liquid separation pipeline. When the next water sample comes, some will be pumped first to rinse the pipeline, which will be discharged as waste liquid. Only one rinsing is required for the same batch of water samples, and then continuous sub-sampling can be carried out.

[0047] This embodiment provides an automatic device for sustainable multi-sample liquid separation. Through the cooperation of the intelligent robotic arm and the lifting platform, operations such as automatically opening the cap, closing the cap, and shaking of the sample bottle are realized, greatly improving the automation degree of liquid separation. Moreover, the design of multi-channel liquid separation tubes is adopted, which supports liquid separation of multiple samples simultaneously, and the liquid separation volume can be accurately controlled, ensuring the accuracy of liquid separation; multiple samples can be liquid-separated simultaneously, and the liquid separation speed is fast, significantly improving the liquid separation efficiency, saving human resources, with a processing efficiency of up to 70 seconds / sample and a processing capacity of 300 - 1200 samples / day. In addition, the utility model can dispense different types and volumes of liquids according to the requirements of different scenarios, and is applicable to liquid separation of samples in a variety of scenarios.

[0048] The above are only the preferred embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structural transformation made under the inventive concept of the present utility model by using the content of the specification and drawings of the present utility model, or direct / indirect application in other related technical fields, is included in the patent protection scope of the present utility model.
