For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] In this embodiment, if Figure 1 and Figure 4 As shown, a fully automatic liquid transfer workstation includes a workbench 1, a robot No. 2 2 and a sample processing device 4 are fixedly installed on the upper surface of the workbench 1, a feed stacking station 3 is also rotatably installed on the upper surface of the workbench 1, the robot No. 2 2 is used to transfer materials between the feed stacking station 3 and the sample processing device 4, the sample processing device 4 includes a shell 401, a lifting door 405 is arranged on the front end surface of the shell 401, a transfer mechanism 403 is arranged in the shell 401, the bottom of the shell 401 has a storage area and a functional area, the functional area is located on one side of the storage area, and the transfer mechanism 403 is used to transfer the bottled samples in the storage area to the corresponding functional area for processing. Further, as Figure 2As shown, the robot No. 2 2 belongs to the prior art. The robot No. 2 2 includes a robot body 201. The output end of the robot body 201 is connected to a feed clamp 202. The feed clamp 202 has a feed clamp fingertip 203. The feed clamp fingertip 203 is used to clamp the material in the feed stacking station 3. By installing the robot No. 2 2 on the workbench 1, when the corresponding material in the feed stacking station 3 needs to be fed into the sample processing device 4, the feed stacking station 3 is rotated so that the required material is facing the robot No. 2 2, and the corresponding material is fed into the sample processing device 4 for processing by the robot No. 2 2. When the material is fed into the sample processing device 4, the bottled sample in the storage area is transferred to the corresponding functional area for processing by the transfer mechanism 403, thereby avoiding manual operation and improving efficiency.

[0031] Further, such as Figure 3 As shown, the feed stacking station 3 includes a base plate 301, which is rotatably mounted on the upper surface of the workbench 1, and is provided with a storage area 302 for vials to be added with liquid, a storage area 303 for original sample tubes, a storage area 304 for boxed tip heads, and a storage area 305 for trays of finished vials. The storage area 302 for vials to be added with liquid, the storage area 303 for original sample tubes, the storage area 304 for boxed tip heads, and the storage area 305 for trays of finished vials are orthogonally distributed on the base plate 301. Specifically, robot No. 2 2 extends its robotic arm to reach the front of the feed stacking station 3 and clamps the material as needed. For example, if we need to clamp the original sample tube 417 here, we first rotate the feed stacking station 3 so that the original sample tube storage area 303 is facing robot No. 2 2. Then robot No. 2 2 controls the feed clamping fingertips 203 to clamp the original sample tube 417 in the original sample tube storage area 303. When it reaches the sample processing device 4, the lifting door 405 is opened, and robot No. 2 2 places the clamped original sample tube 417 in the original sample tube area 411 of the sample processing device 4. After placement, the lifting door 405 is closed; when the processed sample needs to be put back into the feed stacking station 3, the lifting door 405 is opened again, and at the same time, robot No. 2 2 is controlled to put the sample into the feed stacking station 3.

[0032] In this embodiment, if Figure 6As shown, the transfer mechanism 403 includes a support base 601, a first Y-axis 608, a second Y-axis 605, a first X-axis 603 and a second X-axis 606. A plurality of support bases 601 are installed at the bottom of the first Y-axis 608 and the second Y-axis 605, and the first Y-axis 608 and the second Y-axis 605 are installed in parallel. Both ends of the first X-axis 603 and the second X-axis 606 are slidably installed on the first Y-axis 608 and the second Y-axis 605, respectively. An original sample tube clamping module 602 and a liquid aspiration and dispensing module 604 are slidably installed on the first X-axis 603, and a vial processing module 607 is slidably installed on the second X-axis 606. Specifically, the installation method in which both ends of the first X-axis 603 and the second X-axis 606 are slidably installed on the first Y-axis 608 and the second Y-axis 605 is an existing installation method, which can be flexibly selected. The original sample tube clamping module 602 and the liquid aspiration and liquid dispensing module 604 transfer the material by sliding on the first X-axis 603 and the first X-axis 603 sliding on the first Y-axis 608 and the second Y-axis 605. In this embodiment, the original sample tube clamping module 602 and the liquid aspiration and liquid dispensing module 604 move synchronously, and the vial processing module 607 operates in the same principle, which will not be repeated here. In this embodiment, the original sample tube clamping module 602, the liquid aspiration and liquid dispensing module 604 and the vial processing module 607 are all existing modules and can be purchased commercially.

[0033] In this embodiment, the storage area includes an original sample tube area 411, a tip head storage area 410, a vial storage area 408, and a vial finished product tray area 407. The original sample tube area 411, the tip head storage area 410, the vial storage area 408, and the vial finished product tray area 407 are sequentially arranged at the bottom of the shell 401, and the original sample tube area 411 is close to the original sample tube clamping module 602. Further, the functional area includes an original sample tube cover switch mechanism 402, a storage box 412, a vial code scanning module 409, a vial clamping mechanism 404, and a bottle cap conveying device 406. The original sample tube cover switch mechanism 402 is located on one side of the original sample tube area 411, the storage box 412 is located on one side of the tip head storage area 410, the vial code scanning module 409 is located on one side of the vial storage area 408, and the vial clamping mechanism 404 is located on one side of the vial finished product tray area 407. Further, as Figure 7 As shown, the vial clamping mechanism 404 includes a bottom plate a, on which a vial clamping claw 609 is mounted, and a vial clamping fingertip 610 on the vial clamping claw 609 is used to clamp a vial 611. The discharge end of the bottle cap conveying device 406 is located on one side of the vial finished product tray area 407. Specifically, this design is to facilitate the transfer of materials between the storage area and the functional area by the original sample tube clamping module 602, the liquid aspiration and dispensing module 604, and the vial processing module 607, thereby avoiding excessive transfer time and improving efficiency.

[0034] Further, such as Figure 5As shown, the original sample tube cover switch mechanism 402 includes a horizontal transmission module 415, on which an original sample tube clamp 413 is slidably mounted, and the clamping fingertips 414 on the original sample tube clamp 413 are used to clamp the original sample tube 417, and the horizontal transmission module 417 is provided with a sample receiving station and a cover switch scanning station, and the original sample tube clamp 413 passes through the sample receiving station and the cover switch scanning station in sequence, and a cover switch mechanism is provided on one side of the cover switch scanning station. Furthermore, the opening and closing cover mechanism includes a mounting frame, a vertical transmission module 420, an original sample tube cover opening jaw 419 and an original sample tube cover opening fingertip 418. The mounting frame is located on one side of the opening and closing cover scanning station, and the bottom of the mounting frame is installed on the lower surface of the shell 401. The lower end of the mounting frame is installed with an original sample scanner 416, and the original sample scanner 416 is used to scan the barcode on the original sample tube 417. The upper end of the mounting frame is slidably installed with a vertical transmission module 420, and the original sample tube cover opening jaw 419 is installed on the vertical transmission module 420, and the original sample tube cover opening fingertip 418 is installed at the lower end of the original sample tube cover opening jaw 419. Specifically, the experimenter operates the device to move the original sample tube clamping module 602 to the area where the original sample tube area 411 is located. The original sample tube clamping module 602 clamps the designated original sample tube 417 and transfers the original sample tube 417 to the sample receiving station on the horizontal transmission module 417, so that the clamping fingertips 414 on the original sample tube clamping claws 413 clamp the original sample tube 417 to complete the handover; when the original sample tube clamping module 602 clamps the designated original sample tube 417, the liquid aspiration and liquid separation module 604 also reaches the Tip head storage area 410 at the same time, and the liquid aspiration and liquid separation module 604 moves downward to assemble the Tip head onto the working head to wait for subsequent liquid aspiration and liquid separation. When the handover of the original sample tube 417 is completed, the experimenter controls the horizontal transmission module 415 to transfer the original sample The tube 417 is transmitted to the switch cover scanning station. After arriving at the switch cover scanning station, the vertical transmission module 420 is immediately controlled to descend, so that the original sample tube cover opening fingertip 418 clamps the bottle cap of the original sample tube 417. After clamping the bottle cap, the clamping fingertip 414 releases the original sample tube 417, and then the original sample tube cover opening fingertip 418 drives the original sample tube 417 to rotate. During the rotation process, the barcode on the original sample tube 417 is scanned and read by the original sample scanner 416. After the scanning is completed, the clamping fingertip 414 is controlled again to clamp the original sample tube 417, and at the same time, the original sample tube cover opening fingertip 418 on the original sample tube cover opening clamp 419 is controlled to rotate and the vertical transmission module 420 is raised to complete the cover opening action. At this time, the original sample tube cover opening fingertip 418 continues to clamp the bottle cap;After the opening is completed, the horizontal transmission module 415 is controlled again to transmit the opened original sample tube 417 to the sample receiving station, and the Tip head on the liquid aspiration and liquid separation module 604 sucks out the liquid in the original sample tube 417. After the liquid aspiration is completed, the liquid aspiration and liquid separation module 604 is controlled to reach the vial storage area 408, and then the designated empty bottle is filled with liquid. When all the liquid in the same original sample tube 417 is separated, the liquid aspiration and liquid separation module 604 moves to the top of the storage box 412, and the used Tip head is removed, thereby To avoid cross contamination of liquids, after the liquid separation is completed, the horizontal transmission module 415 transmits the original sample tube 417 that has completed the aspiration to the cover opening and closing code scanning station, and then controls the vertical transmission module 420 to descend, and re-closes the bottle cap on the original sample tube opening fingertip 418 on the original sample tube 417. After the cover is closed, the horizontal transmission module 415 transmits the original sample tube 417 to the sample receiving station, and the original sample tube clamping module 602 clamps and transfers the original sample tube 417 back to the original sample tube area 411. In the original position, the opening, closing and code scanning actions of the next original sample tube 417 are started; after the vial is separated, the vial processing module 607 arrives at the vial storage area 408, where the vials are located, and sequentially clamps the vials 611 after the separation to the code scanning area of ​​the vial code scanning module 409 for scanning, the purpose is to correspond to the barcode on the original sample tube 417, so as to facilitate the tracking of subsequent materials. After the code scanning is completed, the vial 611 is transferred to the area where the vial clamping mechanism 404 is located, so that the vial clamping fingertips 66 on the vial clamping claws 609 are clamped. 10 Clamp the bottom of the vial to complete the handover. After the handover is completed, the vial processing module 409 reaches the area where the bottle cap conveyor 406 is located, clamps a bottle cap 503 from the discharge end of the guide groove 501, and moves it to the top of the vial 611, thereby driving the bottle cap 503 to rotate and descend vertically at the same time, completing the capping of the vial 503. After the capping of the vial 503 is completed, the vial clamping fingertip 610 releases the vial 611, and the vial processing module 607 transfers the vial 611 to the vial finished product tray 407, thereby completing the liquid separation operation. In this embodiment, the horizontal transmission module 415, the vertical transmission module 420, the original sample scanner 416 and the vial scanner module 409 are all prior art. ;

[0035] In this embodiment, if Figure 8As shown, the bottle cap conveying device 406 includes a feed bin 505, a partition 504, a conveyor belt 502 and a guide groove 501. Baffles 506 are installed at both ends of the conveyor belt 502. A feed bin 505 is provided at one end of the conveyor belt 502, and the conveyor belt 502 is connected to the discharge end of the feed bin 505. Preferably, the bottom of the feed bin 505 is inclined. In other words, the bottom height of the feed bin 505 close to the conveyor belt 502 is lower than the bottom height of the feed bin 505 away from the conveyor belt 502. The purpose is to guide the bottle caps 503 onto the conveyor belt 502 to avoid the accumulation of the bottle caps 503 in the feed bin 505. The feed bin 505 is located below the bottle cap feed port 5 opened on the surface of the workbench 1. In this embodiment, the experimenter adds the bottle caps 503 into the feed bin 505 through the bottle cap feed port 5. A plurality of partitions 504 are arranged at equal intervals on the surface of the conveyor belt 502, and the surface of the partition 504 matches the taper of the bottle cap 503 in the height direction. A guide groove 501 is arranged at the other end of the conveyor belt 502, and the feed end of the guide groove 501 is connected to the discharge end of the partition 504, and the discharge end of the guide groove 501 is located on one side of the finished bottle tray area 407. Further, the conveyor belt 502 is arranged obliquely, and the feed bin 505 is located at the lower end of the conveyor belt 502, and the guide groove 501 is located at the upper end of the conveyor belt 502. In other words, the bottle cap 503 is lifted and transported from bottom to top. The bottle caps 503 in the feed bin 505 are transported by the conveyor belt 502. Since the surface of the partition 504 matches the taper in the height direction of the bottle caps 503, when the surface of the bottle caps 503 do not fit with the partition 504, the bottle caps 503 will fall into the feed bin 505 again due to their own weight and wait for secondary feeding and lifting, so that the direction of the bottle caps 503 can be selected to avoid manual adjustment; and the baffles 506 at both ends of the conveyor belt 502 can prevent the bottle caps 503 from falling during the transmission of the bottle caps 503, and the guide groove 501 is used to adjust the direction of the bottle caps 503, so as to facilitate the grabbing of the small bottle processing module 607, thereby improving work efficiency.

[0036] Furthermore, the partition 504 has an inclined surface in the length direction, which is inclined in the direction of the guide groove 501, and the surface of the inclined surface matches the taper in the height direction of the bottle cap 503. That is to say, the upper end of the partition 504 is in the shape of an inclined surface, and its purpose is to make the bottle cap 503 roll in the direction of the guide groove 501 due to its own weight. Since baffles 506 are provided at both ends of the conveyor belt 502, the baffles 506 will block the bottle cap 503 during the transmission process to prevent the bottle cap 503 from rolling to the outside of the conveyor belt 502. The surface of the inclined surface matches the taper in the height direction of the bottle cap 503, that is, the inclined surface is not perpendicular to the conveyor belt 502, and the surface of the inclined surface matches the taper of the bottle cap 503, thereby ensuring that only the bottle cap 503 with the opening facing outward can be lifted upward, and the surfaces of the remaining bottle caps 503 will fall into the feed bin 505 again due to their own weight because they do not match the inclined surface and wait for secondary feeding and lifting.

[0037] In this embodiment, both sides of the guide groove 501 are provided with limit baffles. Specifically, the conveyor belt 502 drives the bottle caps 503 to lift upward, and when the partition 504 on the surface of the conveyor belt 502 is connected with the guide groove 501, the bottle caps 503 will roll into the guide groove 501 due to their own weight, and the bottle caps 503 will slide in the guide groove 501 to the discharge end of the guide groove 501 to wait for the subsequent vial processing module 607 to grab them, and the limit baffles can prevent the bottle caps 503 from sliding off the guide groove 501.

[0038] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
