[0050] In some embodiments, the depth direction of the receiving groove is consistent with the vertical direction, and the door of the temperature control cabinet and the slot of the receiving groove, i.e., the tabletop of the operation table 1, are flush, to facilitate the execution end of the material moving device 2 to open or close the door.

Alternatively, the door is a sliding door, and the execution end of the material moving device 2 clamps the handle of the door and opens or closes the door with the horizontal movement of the execution end of the material moving device 2.

[0052] The positioning seat is fixed to the tabletop of the operation table 1. The detection container containing the sample to be tested is inserted into the positioning groove to limit the position of the detection container by the positioning seat, to ensure that the detection container does not shift during titration of the reagent. After the material moving device 2 opens the door, it grabs the reagent bottle 21 and moves the reagent bottle 21 to the side of the positioning seat.

[0053] Alternatively, the tabletop of the operation table 1 is provided with a pipette. The operation table 1 is fixedly provided with a fixing seat. The fixing seat is provided with a receiving groove. The material moving device 2 inserts the reagent bottle 21 into the receiving groove, limits the position of the reagent bottle 21 by the groove wall of the receiving groove, then unscrews the cap of the reagent bottle 21 by the material moving device 2, and then grabs and operates the pipette to suck the reagent in the reagent bottle 21 and titrate the reagent into the sample to be tested. After titration, the material moving device 2 re-tightens the cap of the reagent bottle 21, and then puts the reagent bottle 21 back into the temperature control cabinet and closes the door.

[0054] The incubation device is fixedly installed on the operation table 1. The mechanical arm 3 moves the sample after titration of reagents to the incubation device for incubation. The incubation device can provide a suitable temperature and nutrient environment for microbial colonies and somatic cells. According to different detection indexes, the user can select the related equipment of the incubation device to culture microbial colonies or somatic cells in the sample. After the culture is completed, the mechanical arm 3 moves the sample to the detector 5 for detection of the content of microbial colonies or somatic cells.

[0057] In some embodiments, as shown in Figure 2 Reagent bottle 21 is fixedly installed on fixed support 6. The mouth of reagent bottle 21 is provided with a liquid distributor 7. The suction tube of liquid distributor 7 is inserted into reagent bottle 21.

[0058] The operation table 1 is fixedly installed with a limiting seat. The limiting seat has a limiting groove.

[0059] The material moving device 2 is used to take out the fixing support 6 from the temperature control cabinet and place it in the limiting groove, so as to add the reagent in the reagent bottle 21 into the sample to be measured through the dispenser 7, and is used to take out the fixing support 6 from the limiting groove after the addition is completed to put the reagent bottle 21 back into the temperature control cabinet.

[0060] Specifically, the fixing support 6 is a frame structure. As shown in Figure 2 The bottom of the fixing support 6 is provided with a groove body which is adapted to the shape of the reagent bottle 21. The reagent bottle 21 is inserted in the groove body. The dispenser 7 is clamped in the fixing support 6. The fixing support 6 provides support for the reagent bottle 21 and the dispenser 7 at the same time. The bottle cap of the reagent bottle 21 is provided with a connecting hole for the liquid suction tube of the dispenser 7 to pass through. The liquid suction tube of the dispenser 7 passes through the connecting hole and is inserted into the reagent.

[0061] The fixing support 6, the dispenser 7 and the reagent bottle 21 are assembled as a whole and are stored in the temperature control cabinet together. When titration of the reagent is needed, the material moving device 2 opens the cabinet door of the temperature control cabinet, then clamps the fixing support 6, and takes out and inserts the fixing support 6 into the limiting groove. The position of the fixing support 6 is limited by the groove wall of the limiting groove to prevent displacement of the reagent bottle 21 and the dispenser 7 during titration of the reagent. By fixing the fixing support 6 to the reagent bottle 21, on the one hand, the material moving device 2 can take out the reagent bottle 21 and the dispenser 7 at the same time, and on the other hand, the fixing support 6 fixes the reagent bottle 21 and the dispenser 7 to ensure the stability of the dispenser 7 during titration of the reagent.

[0062] In this embodiment, the positioning seat and the limiting seat are arranged adjacent to each other. After the fixing support 6 is inserted into the limiting groove, the liquid outlet of the dispenser 7 is just located above the detection container. At this time, the flow switch 71 of the dispenser 7 is screwed by the material moving device 2 to adjust the titration amount of the reagent. After the adjustment is completed, the piston of the dispenser 7 is pulled by the material moving device 2, and the reagent automatically flows into the sample to be measured from the liquid outlet of the dispenser 7, thereby completing the titration of the reagent.

[0063] After the titration is completed, the fixing support 6 is pulled out from the limiting groove by the material moving device 2, and the fixing support 6, the reagent bottle 21 and the dispenser 7 are re-transported into the temperature control cabinet, and then the cabinet door of the temperature control cabinet is closed.

[0064] In some embodiments, the mechanical arm 3 includes a main body, a first claw body and a second claw body. At least one of the first claw body and the second claw body is movably installed at the end of the main body.

[0065] Specifically, the end of the main body is fixedly provided with a driving member. Optionally, the driving member is a telescopic motor. The first claw body and the second claw body are oppositely arranged. The first claw body is fixed to the main body, and the driving end of the driving member is connected with the second claw body to drive the second claw body to move close to or away from the first claw body, so as to adjust the opening and closing degree of the first claw body and the second claw body, so that the mechanical arm 3 can pick up detection containers of different specifications. Alternatively, the first claw body and the second claw body are both movably installed on the main body. The driving member is a double-shaft telescopic motor, which can simultaneously drive the first claw body to move close to or away from each other, and the above-mentioned effect can also be achieved.

[0066] In some embodiments, the first claw body and the second claw body are both conical grooves to adapt to detection containers of different sizes.

[0067] Specifically, the detection container is in a cylindrical shape. The notches of the conical grooves of the first claw body and the second claw body are oppositely arranged, and form an arc-shaped clamping part that matches the shape of the detection container. This can not only increase the clamping force of the first claw body and the second claw body on the detection container, ensuring the stability of the detection container during the transfer process, but also ensure that the first claw body and the second claw body can clamp detection containers of different specifications, and have good versatility.

[0068] In some embodiments, as shown in Figure 1 The six-axis mechanical arm is installed between the temperature control cabinet and the positioning seat, so that the six-axis mechanical arm can open the cabinet door of the temperature control cabinet to take out the reagent bottle 21 from the temperature control cabinet, so that the reagent in the reagent bottle 21 can be added to the sample to be tested. After the addition is completed, the six-axis mechanical arm puts the reagent bottle 21 back into the temperature control cabinet and closes the cabinet door. The six-axis mechanical arm and the mechanical arm 3 perform corresponding operations at the same time without waiting time, which improves the detection efficiency of the microbial rapid detection.

[0069] The six-axis mechanical arm can be a humanoid robot hand or a joint robot hand of the prior art.

[0070] In some embodiments, the six-axis mechanical arm includes a body and a clamp installed at the end of the body. The clamp includes a first clamping jaw and a second clamping jaw. The first clamping jaw and the second clamping jaw each have a first connecting groove. The first connecting groove is used in cooperation with the fixed support 6. The fixed support 6 includes a plurality of interconnected vertical rods. The two first connecting grooves are oppositely arranged to form a clamping part, so that the first clamping jaw and the second clamping jaw can better clamp the vertical rods of the fixed support 6, ensuring the stability of the fixed support 6 during the transfer process and preventing the fixed support 6 from tipping over.

[0071] In other embodiments, the first clamping jaw and the second clamping jaw are respectively provided with protrusions at the ends away from the body.

[0072] Specifically, the two protrusions are oppositely arranged to form a screwing part. The screwing part is used to simulate the ergonomics of a finger to screw the flow switch 71 of the dispenser 7, so as to facilitate the clamp to perform the operation of adjusting the flow of the dispenser 7. Wherein, the side of each protrusion in contact with the flow switch 71 is provided with a second connecting groove to increase the friction between the screwing part and the flow switch 71, so as to ensure the strength of the clamp in screwing the flow switch 71.

[0073] In some embodiments, the material moving device 2 comprises a door opening mechanism and a moving module. The door opening mechanism is fixed to the operation table and is used to open or close the cabinet door of the temperature control cabinet. Optionally, the cabinet door is a sliding cabinet door, and the door opening mechanism is an electric push rod. The extension end of the electric push rod is connected with the handle on the cabinet door to drive the cabinet door to open or close.

[0074] Optionally, the moving module comprises a linear motion module, a connecting seat and a clamp. The linear motion module is installed on the operation table. The connecting seat is installed on the sliding table of the linear motion module in a lifting manner. The connecting seat can move back and forth between the temperature control cabinet and the limiting groove along with the sliding table. The clamp is installed on the connecting seat. The clamp can take out and put back the reagent bottle 21 from the temperature control cabinet along with the lifting of the connecting seat, and can also place the taken-out reagent bottle 21 in the limiting groove and clamp the reagent bottle 21 from the limiting groove.

[0075] Specifically, the linear motion module can be a pneumatic linear module, a linear motor linear module or a linear guide rail module in the prior art. The clamp can extend into or exit the temperature control cabinet along with the extension and retraction of the connecting seat, so as to grab the reagent bottle 21 or put the reagent bottle 21 back into the temperature control cabinet.

[0076] In the case that the reagent bottle 21 is fixedly installed on the fixed support 6, after the opening and closing mechanism opens the cabinet door, the controller controls the sliding table of the linear motion module to move to the position of the temperature control cabinet, and then the connecting seat moves downward to make the clamp grab the fixed support 6. After grabbing, the connecting seat moves upward to take out the reagent bottle 21 from the temperature control cabinet. Then the controller controls the sliding table of the linear motion module to move towards the limiting seat, and after moving above the limiting seat, the connecting seat moves downward, and the clamp inserts the fixed support 6 into the limiting groove.

[0077] In some embodiments, the microbial rapid detection work station further comprises a pipette. The operation table is fixedly installed with a plug-in rack 14. The pipette is inserted into the plug-in rack 14.

[0078] The operation table 1 is installed with a positioning tray 16. The positioning tray 16 has a clamping groove for accommodating a sample bottle containing a sample.

[0079] The mechanical arm 3 is used to grab and move the pipette to the sample bottle, so that the pipette can suck the sample in the sample bottle and titrate the sample into a detection container accommodated in the positioning groove.

[0080] Specifically, the positioning tray 16 is fixed to the operating table 1. The positioning tray 16 has multiple slots of different sizes to accommodate multiple sample vials of different sizes. During testing, the sample vials containing the samples to be tested are transferred to the positioning tray 16 manually or by a mobile robot, so that the robotic arm 3 can pick up the samples on the positioning tray 16 for subsequent testing.

[0081] Sample identification codes are affixed to the sample vials. A barcode scanning camera is installed on robotic arm 3. By scanning the sample identification code, the host computer can determine the testing items for the sample and control robotic arm 3 to perform the corresponding actions. For samples requiring microbial colony content and somatic cell content testing, robotic arm 3 grasps and operates the pipette, causing the pipette to aspirate the sample from positioning tray 16 and titrate it into the testing container located in the positioning slot. The holder has multiple insertion holes to accommodate multiple pipettes. Each pipette is discarded after a single sample aspiration and is transported by the robotic arm to the pipette recycling area for disposal.

[0082] The rapid microbial testing station provided by this invention can also be used to test the viscosity of dairy products. For example... Figure 1 As shown, the rapid microbial testing station also includes a viscometer 8. The viscometer 8 is mounted on the operating table 1. The robotic arm 3 is used to transfer another sample to be tested to the viscometer 8 for viscosity measurement.

[0083] For samples that require viscosity testing, the robotic arm 3 transfers the sample from the positioning tray 16 to the viscometer 8 for viscosity testing.

[0084] Optionally, the viscometer 8 can be a rotational viscometer or a vibrational viscometer.

[0085] In some embodiments, such as Figure 1 As shown, the operating table 1 is equipped with a heating device 9. The robotic arm 3 is used to transfer the sample to be tested to the heating device 9 for heating, and then transfer the heated sample to the viscometer 8 for viscosity measurement.

[0086] It should be noted that for some test samples with high coagulation and viscosity, such as yogurt, heating is required before viscosity testing to dilute them. The heating device 9 can be a water bath heater. When the host computer identifies that the test sample needs heating based on the sample identification code, it controls the robotic arm 3 to move, which then transfers the sample bottle to the heating device 9. After heating, the sample is transferred to the viscometer 8 for viscosity measurement.

[0087] In some embodiments, such as Figure 1As shown, the operation table 1 is also provided with a fixed tray 10. The fixed tray 10 is provided with slots for inserting the heating container 20. The mechanical arm 3 is used to pour the sample to be tested into the heating container 20, and move the heating container 20 to the heating device 9, and move the heating container 20 to the viscometer 8 for viscosity detection after the heating of the sample to be tested is completed.

[0088] Specifically, the fixed tray 10 is fixed to the operation table 1. The slots are provided in multiple. The multiple slots are of different specifications, so as to be able to insert heating containers 20 of multiple specifications, and thus the mechanical arm 3 can select the heating container 20 of the corresponding specification according to the type of the sample to be tested. When the host computer identifies the sample type and the sample to be tested needs to be heated according to the sample identification code, the host computer controls the movement of the mechanical arm 3, the mechanical arm 3 picks up the sample bottle, moves the sample bottle to above the heating container 20 of the corresponding specification, then pours the sample bottle, pours the sample to be tested into the heating container 20, and then moves the heating container 20 into the heating device 9 by the mechanical arm 3 for heating. After the heating is completed, the heating container 20 is moved to the viscometer 8 by the mechanical arm 3 for viscosity detection.

[0089] The waste detection container after detection can be collected by the mobile robot walking between the workstations and sent to the cleaning workstation for unified cleaning, and the clean detection container is sent back to the microbial rapid detection workstation by the mobile robot after cleaning. In some embodiments, as shown in Figure 1 As shown, the microbial rapid detection workstation also includes a cleaner 30. The cleaner 30 is installed on the operation table 1. The mechanical arm 3 is used to move the waste detection container after detection to the cleaner 30 for cleaning.

[0090] When the sample is detected, the waste detection container is directly moved from the detector 5 to the cleaner 30 by the mechanical arm 3 for cleaning, without manual cleaning, saving labor cost.

[0091] In some embodiments, the table surface of the operation table 1 is provided with a container storage area. After cleaning, the clean detection container is moved to the container storage area by the mechanical arm 3. In other embodiments, the clean detection container is placed in the installation cabinet 11 by manual for storage and standby.

[0092] Optionally, the cleaner 30 is a mechanical rotary cleaner or a chemical cleaner.

[0093] As shown in Figure 1 The operation table 1 is also provided with a peristaltic pump 40 and a cleaning agent tank. The cleaning agent tank is provided with cleaning agent. The liquid inlet of the peristaltic pump 40 and the liquid outlet of the cleaning agent tank are connected.

[0094] The mechanical arm 3 is used to move the waste detection container after detection to the lower side of the peristaltic pump 40, so that the peristaltic pump 40 titrates the cleaning agent into the waste detection container, and is used to move the waste detection container titrated with the cleaning agent to the cleaner 30.

[0095] Specifically, the cleaning agent tank is placed in the placement cabinet 15. The liquid inlet of the peristaltic pump 40 extends into the placement cabinet 15 and is connected with the liquid outlet of the cleaning agent tank. When the sample is detected, the waste detection container is moved by the mechanical arm 3 from the detection instrument 5 to the lower side of the outlet of the peristaltic pump 40. The mechanical arm 3 holds the waste detection container, and at the same time, the host controls the peristaltic pump 40 to start, and the peristaltic pump 40 titrates the cleaning agent in the cleaning agent tank into the waste detection container. Then, the mechanical arm 3 moves the waste detection container containing the cleaning agent to the cleaner 30 for cleaning.

[0096] In some other embodiments, as shown in Figure 1 The microbial rapid detection work station further includes a recovery rack 50. The recovery rack 50 is placed on the operation table 1. The cleaner 30 is an ultrasonic cleaner 30. The recovery rack 50 has a plurality of insertion holes. The mechanical arm 3 is used to insert the plurality of waste detection containers into the plurality of insertion holes one by one, and move the recovery rack 50 to the ultrasonic cleaner 30.

[0097] Specifically, the insertion holes have different specifications so as to be able to insert waste detection containers of different specifications. After detection, the mechanical arm 3 inserts the plurality of waste detection containers into the insertion holes of corresponding specifications one by one. Then the entire recovery rack 50 is grabbed to place all the waste detection containers on the recovery rack 50 in the cleaning liquid in the ultrasonic cleaner 30 for batch cleaning, which improves the cleaning efficiency of the cleaner 30, simplifies the operation, and saves the energy consumption of the cleaner 30. In this embodiment, the plurality of waste detection containers can be kept stationary during cleaning by the ultrasonic cleaner 30, and the waste detection containers do not need to be rotated or shaken, so that the waste detection containers are not easily damaged.

[0098] The incubation device includes an incubator and an ultrasonic incubator. The incubator is used to culture the microbial colonies and / or somatic cells in the sample after titration of the reagent.

[0099] The main function of the incubator is to provide an ideal environment for the propagation of microbial colonies and / or somatic cells, so that the microbial colonies and somatic cells can grow and propagate rapidly under appropriate temperature and humidity conditions, facilitating the subsequent counting and identification of the microbial colonies and somatic cells.

[0100] When it is necessary to detect the content of microbial colonies in the sample, the mechanical arm 3 moves the sample after titration of the reagent to the incubator for incubation, and then moves the sample with the incubated microbial colonies from the incubator to the detection instrument 5 for detection of the microbial colonies.

[0101] The ultrasonic incubator is used for secondary incubation of the sample to be detected after the somatic cells are incubated. The ultrasonic incubator can maintain the temperature environment required for somatic cell incubation, and increase the permeability of the cell membrane through the vibration of the ultrasonic wave, so as to help the nutrients or drugs to enter the somatic cells more effectively, thereby promoting the growth of the somatic cells.

[0102] When it is necessary to detect the content of somatic cells in the sample to be detected, the mechanical arm 3 moves the sample to be detected of the titration reagent to the incubator for incubation of the somatic cells, and then moves the sample to be detected of the incubated somatic cells from the incubator to the ultrasonic incubator for secondary incubation, and then moves the sample to be detected after the secondary incubation to the detector 5 for detection of the content of the somatic cells.
