[0002] The way to find infected persons is to collect the nucleic acid of the human body and judge whether they are infected through detection. So far, the work of collecting nucleic acid is basically carried out by medical staff. They work intensively every day, wearing isolation protective clothing, and are more likely to have various physical discomforts in hot summer. Based on this situation, many nucleic acid sampling robots have emerged. However, these systems are still in the initial stage of research and development. Only the sampling actions of the robotic arm are designed accordingly, and the number of test tubes is not large enough to be truly put into daily use. Some sampling robots need to be equipped with bite blocks, and the subjects also need to flip open the cover to get the bite block and press the start button by themselves, making it difficult to achieve true non-contact. To solve this problem, the present invention proposes a full-automatic non-contact nucleic acid sampling robot system, which organically integrates a flexible robotic arm and a small automated production line. It not only has automatic loading and unloading of test tubes, code scanning, automatic opening and closing of bottle caps, and automatic shearing of swabs, but also has automatic sampling and disinfection of the robotic arm, realizing full-process automation.

The purpose of putting clear water into the alcohol recycling bottle E2 is to reduce the alcohol concentration and reduce the risk.

[0032] The working principle of this embodiment is as follows:

[0033] When the system is in the waiting state, the loading and transferring manipulator A moves above the corresponding position of the test tube rack 2, descends, picks up one test tube 3 from the test tube rack 2, ascends, and then translates to wait above the test tube loading position C3-1. The unloading and transferring manipulator B waits above the test tube picking position C3-5. The capping manipulator D waits above the code scanning and uncapping position C3-2. The clamping electric claws C5 around the rotary table C are in the retracted state, the jaws are opened, the swab shearing jaws C6 are opened, the scissors C7 are opened, and the robotic arm J waits at the swab picking position.During operation, the person to be tested first stands in front of the thermometer 1-1 for temperature measurement. If the body temperature is abnormal, they will be prompted to leave and cannot use the system for automatic sampling. If the body temperature is normal, they can continue. Take out the nucleic acid code and scan it in front of the code reader 1-2. Then, follow the prompts of the voice system to perform each of the following steps. That is, stand in front of the sampling room, open your mouth facing the sampling port, and wait with your mouth wide open. At the same time as the code scanning is completed, the mechanical logistics system W and the robotic arm J start working simultaneously. The loading transfer manipulator A loads the unused test tube 3 into the loading test tube seat C3-1 of the rotary table C. The rotary table C rotates by one indexing angle for the first time. The capping manipulator D descends, grabs the test tube 3 at the capping position and ascends, rotates the test tube 3, and the barcode scanner 6 reads the QR code data on the test tube 3 and sends it to the total control system for binding with the person's nucleic acid code. The capping manipulator D descends and places the test tube 3 back into the test tube seat D3-2. At this time, the clamping electric claw I moves forward and clamps the test tube 3. The capping manipulator D rotates counterclockwise, loosens the cap of the test tube 3 and ascends. The cap is held in the capping manipulator D and is translated to the test tube capping position C3-4 to wait. The rotary table C rotates by one indexing angle for the second time. The test tube 3 with the cap removed is located at the swab shearing position C3-3 and waits for the robotic arm J to sample. At the same time, the robotic arm J moves to the automatic swab stripper 5, the gripper J7 grabs the swab 7 and takes it out to the sampling position. At this time, after the visual inspection system detects the oral cavity shape, it sends information to the robotic arm J. The robotic arm J drives the swab 7 to sample on the left and right sides of the oral cavity. After the sampling is completed, the robotic arm J moves to the swab shearing position C3-3 of the rotary table C, inserts the swab 7 into the test tube 3, and the scissors C7 cut the rod of the swab 7. Then the robotic arm J throws the rod of the swab 7 into the swab rod hopper E7 and it falls into the swab rod recycling bin E5 below. The robotic arm J then moves to the disinfection station E6-1, inserts the end of the robotic arm J into the disinfection box E6, and is disinfected by alcohol spraying. Then it returns to the swab picking position to wait for the next operation. After the swab shearing action is completed, the rotary table C rotates by one indexing for the third time. The test tube 3 with the sampled swab is transported to the test tube capping position C3-4. The clamping electric claw C5 extends and clamps the test tube 3. The capping manipulator D descends and rotates clockwise to tighten the cap on the test tube 3. The rotary table C rotates by one indexing for the fourth time. The test tube 3 that has completed sampling is transported to the test tube unloading position C3-5. The unloading transfer manipulator B descends to grab the test tube 3, ascends, then translates to the corresponding placement position, descends and places the test tube 3 into the test tube rack 2, and then returns to wait above the test tube picking position C3-5.
