[0040] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0041] The following is combined Figures 1 to 2 The raw milk adulteration detection device provided by the present invention will be described in detail through specific embodiments and application scenarios.

[0042] like Figure 1 and Figure 2 As shown, this embodiment provides a raw milk adulteration detection device, including: a test platform 1, a sampling component 2, a reagent addition component 3, a robot 4, and a vision detection component 5; the sampling component 2, the reagent addition component 3, the robot 4, and the vision detection component 5 are all installed on the test platform 1.

[0043] The test stand 1 has an experimental vessel placement area 11 and a sample placement area 12.

[0044] Sampling component 2 is used to sample the sample and add the sample to the experimental vessel.

[0045] The reagent adding component 3 is used to add reagents to the experimental vessel located at the reagent adding position.

[0046] Robot 4 is used to transfer experimental vessels with added samples to the reagent adding position and to transfer experimental vessels with added samples and reagents to the vision inspection component 5.

[0047] The visual inspection component 5 is used to visually inspect the liquid in the experimental vessel to determine whether the impurity content in the sample exceeds the standard.

[0048] To detect adulteration in raw milk samples, a detection reagent is added to the raw milk sample, and visual inspection is used to determine whether the impurity content in the sample exceeds the standard.

[0049] The laboratory glassware placement area 11 is used to place test tubes, petri dishes, and other laboratory glassware, while the sample placement area 12 is used to place bottles containing raw milk samples. The laboratory glassware placement area 11 includes a fixedly mounted test tube rack and / or petri dish rack. The test tube rack has multiple test tube insertion positions. The petri dish rack has grooves for accommodating petri dishes. The grooves are vertically deep, allowing multiple petri dishes to be stacked within a single groove.

[0050] Sampling component 2 can collect raw milk samples and add them to experimental dishes.

[0051] In one embodiment, robot 4 can transfer experimental vessels from experimental vessel placement area 11 to sample addition position, and then sampling component 2 can aspirate a certain amount of sample from the raw milk bottle in sample placement area 12 and transfer it to the experimental vessel in sample addition position. Thus, raw milk sample is added to the experimental vessel through the cooperation of sampling component 2 and robot 4. In another embodiment, the entire sampling operation can be completed by using only sampling component 2 to transfer experimental vessels from experimental vessel placement area 11 to sample addition position and to aspirate a certain amount of sample from the raw milk bottle in sample placement area 12 to the experimental vessel in sample addition position.

[0052] In addition, the raw milk adulteration detection device also includes a scanning structure capable of identifying information about the sample to be tested. Optionally, the scanning structure can be fixed on the test stage 1 or integrated into the robot 4, as long as it can scan the raw milk bottle to record the data of the sample being taken at that time.

[0053] The visual inspection component 5 performs visual sensory inspection of the mixture of sample and reagent in the experimental vessel. The visual inspection component 5 is equipped with a shooting structure and a recognition system, which can take pictures of the liquid in the experimental vessel and determine the state of the sample at this time through the recognition system.

[0054] In practical applications, sampling component 2 takes samples from raw milk bottles in the sample placement area 12 and adds the samples to experimental vessels. Robot 4 carries the experimental vessels and transfers them between various workstations. After adding reagents to the experimental vessels containing the samples, visual inspection component 5 performs visual inspection. Sampling component 2 is mainly used for sample acquisition and addition, while robot 4 is mainly used for transferring experimental vessels between workstations. While robot 4 is transferring experimental vessels containing samples, sampling component 2 can simultaneously add the next sample. Sampling component 2 separates the sample acquisition and addition actions from robot 4, eliminating the need for robot 4's involvement in both time and space. This concentrates the workload of robot 4 on the transfer of experimental vessels, allowing the sampling and addition of different samples to be carried out simultaneously with reagent addition and visual inspection, shortening the detection time for raw milk adulteration and improving the efficiency of raw milk adulteration detection.

[0055] In some embodiments, the raw milk adulteration detection device further includes a water bath heating component 27 disposed on the test stage 1 for performing heating, boiling and cooling operations during the experiment.

[0056] The specific type and structure of the water bath heating element 27 are not limited, and any known water bath heating element 27 can be used.

[0057] In some embodiments, the raw milk adulteration detection device further includes a mixing component 26 disposed on the test stage 1. The mixing component 26 is communicatively connected to the robot 4 and can be used for mixing operations with high requirements during the experiment. It has a simple and reliable structure.

[0058] The specific type and structure of the mixing component 26 are not limited, and a known mixing component 26 can be used.

[0059] Specifically, the mixing component 26 is an oscillator with a vortex oscillation structure.

[0060] The specific structure of the oscillator can be referenced from the structure of a well-known vortex oscillator.

[0061] The raw milk adulteration detection device provided by this utility model completes the sample collection and addition of the sample to the experimental vessel by setting up a sampling component 2, and completes the work of picking up the experimental vessel and moving it between the reagent addition position and the visual detection component 5 by setting up a robot 4. This makes the sample collection and addition independent of the holding of the robot 4. When the robot 4 is performing reagent addition and visual detection of the previous sample, the sampling component 2 can simultaneously perform the sampling and addition of the next sample. Compared with the robot 4 completing the sampling and transfer of the experimental vessel by itself, which requires the robot 4 to complete both sampling and transfer of the experimental vessel in a single thread, the sampling component 2 in this embodiment can reduce the workload of the robot 4, shorten the raw milk adulteration detection time, and improve the efficiency of raw milk adulteration detection.

[0062] In some embodiments, such as Figure 1 As shown, the sampling component 2 in this embodiment includes a robotic arm 21, a pipette 22, a pipette tip 23, and a placement rack 24.

[0063] A pipette 22 is installed at the end of the robotic arm 21.

[0064] The rack 24 holds multiple pipette tips 23 of different sizes. The robotic arm 21 can drive the pipette 22 to assemble with one of the pipette tips 23, and after assembly, it can move to the sample placement area 12 to pick up the sample and transfer it to the experimental vessel.

[0065] For different doping detection experiments, the required sample dosage varies. When aspirating samples, the pipette tip 23 can only extract a fixed quantity of sample. Therefore, different dosages require different pipette tips 23. Furthermore, after aspirating a sample with the pipette tip 23, performing another sample aspiration can easily cause sample contamination. Therefore, the pipette tip 23 needs to be replaced after each sample aspiration. In this embodiment, the pipette tip 23 is a disposable item.

[0066] The robotic arm 21 is mounted on the test stage 1 and can rotate relative to the test stage 1 to move between the placement rack 24 area, the sample placement area 12, and the sample addition position of the experimental vessel.

[0067] Specifically, the robotic arm 21 drives the pipette 22 to press the pipette tip 23, so that the pipette tip 23 is engaged with the pipette 22, and the pipette tip 23 is installed on the pipette 22. Then, the robotic arm 21 moves the pipette 22 and the pipette tip 23 to the sample placement area 12 to draw the sample from the raw milk bottle. Next, the robotic arm 21 moves the pipette 22 and the pipette tip 23 to the sample addition position and adds the sample drawn from the pipette tip 23 into the experimental vessel.

[0068] Specifically, the placement rack 24 of this embodiment displays three sizes of nozzles 23, which can respectively draw 1ml, 2ml and 3ml of sample.

[0069] Accordingly, the pipette 22 in this embodiment can be fixedly connected to the robotic arm 21, and the range of the pipette 22 can be adjusted by controlling the robotic arm 21. Alternatively, the pipette 22 can be detachably connected to the robotic arm 21, and different range specifications of pipette 22 can be used for different ranges.

[0070] In this embodiment, the sampling component 2 is equipped with a robotic arm 21, a pipette, a pipette tip 23, and a placement rack 24. The robotic arm 21 can drive the pipette 22 to assemble with pipette tips 23 of different specifications on the placement rack 24, and pick up the sample and add it to the experimental vessel. Different specifications of pipette tips 23 are used for different experiments, and clean pipette tips 23 can be used for each sampling, avoiding sampling contamination. The structure is simple and the sampling is convenient.

[0071] In some embodiments, such as Figure 1 As shown, the placement rack 24 in this embodiment includes a first sampling rack 241 and a second sampling rack 242.

[0072] The first sampling rack 241 is used to hold the pipette 22.

[0073] The second sampling frame 242 has multiple insertion holes, and the gun head 23 is vertically inserted into the insertion holes.

[0074] When the pipette 22 corresponds to different volume ranges, different specifications of pipette 22 are used. The first sampling frame 241 is used to place the pipette 22 and can load the pipette 22. The robotic arm 21 moves to the first sampling frame 241, automatically grabs the pipette 22 and installs it.

[0075] Meanwhile, the second sampling frame 242 is used to place the pipette tip 23. Since the robotic arm 21 needs to complete the assembly of the pipette 22 and the pipette tip 23, the pipette tip 23 needs to be vertically arranged on the second sampling frame 242. Therefore, the second sampling frame 242 is provided with multiple insertion holes, and the pipette tip 23 can be vertically inserted into the insertion holes. The placement of the pipette tip 23 on the second sampling frame 242 is in a vertical state, which facilitates the pressing operation of the pipette tip 23 by the pipette 22.

[0076] In some embodiments, such as Figure 1 As shown, the wall of the insertion hole in this embodiment is filled with a silicone pad to buffer the pick-up pressure of the pipette 22 on the tip 23.

[0077] When the pipette 22 presses down on the tip 23 to pick up the tip 23, the tip 23 bears the downward pressure of the pipette 22. In order to buffer the picking pressure, this embodiment fills the hole wall with a silicone pad. The flexible material of the silicone pad can absorb the impact force and reduce vibration when the tip 23 is subjected to vertical pressure, thus avoiding damage to the tip 23.

[0078] In some embodiments, such as Figure 1 As shown, the second sampling frame 242 is equipped with a pressure sensor.

[0079] A pressure sensor detects the pressure applied when the pipette 22 presses down on the tip 23 to pick up the liquid, and is communicatively connected to the robotic arm 21. Optionally, the pressure sensor can be a pressure-sensitive sensor or other type of sensor. Optionally, the pressure sensor is located on the wall of the insertion port, and can detect the pressure applied by the pipette 22 to the tip 23 when the pipette 22 presses down on the tip 23.

[0080] When the pipette 22 presses down on the pipette tip 23, the pressure sensor sends feedback of the pressing pressure to the robotic arm 21. If the pressure is too high, the robotic arm 21 is alerted to stop pressing to avoid damage to the pipette tip 23. When the pressure reaches the set value, the pipette 22 stops pressing down, thus ensuring that the pipette tip 23 is consistently securely installed. This effectively indicates that the device operation of the pipette tip 23 and the pipette 22 is complete, without the need for manual judgment.

[0081] In some embodiments, such as Figure 1 As shown, the sampling component 2 in this embodiment also includes a waste tank 25.

[0082] Waste tank 25 is located on test bench 1 and is used to hold waste gun heads 23.

[0083] After sample collection is completed, the robotic arm 21 removes the discarded pipette tip 23 and places it into the waste container 25 so that a clean pipette tip 23 can be assembled for the next sample collection. Specifically, the pipette 22 is equipped with a release button. After the pipette tip 23 picks up the sample, the robotic arm 21 triggers the release button to remove the pipette tip 23 from the pipette 22.

[0084] Optionally, in this embodiment, the waste trough 25 is located on the lower side of the first sampling frame 241. The first sampling frame 241 and the waste trough 25 are arranged compactly, saving space on the test bench 1.

[0085] In some embodiments, such as Figure 1 As shown, the reagent addition component 3 in this embodiment includes a reagent tank, a peristaltic pump, and a stand.

[0086] Multiple reagent tanks and peristaltic pumps are provided. Multiple reagent tanks are located on test bench 1, and multiple peristaltic pumps are installed on the stand. Multiple reagent tanks and multiple peristaltic pumps are set up one-to-one, and different reagents are contained in multiple reagent tanks.

[0087] In this embodiment, a shelf is provided under the test platform 1, on which multiple reagent containers are arranged, saving space on the test platform. A stand is placed on the test platform 1, and multiple peristaltic pumps are installed on the stand. The lower side of the stand forms a reagent addition position. Different reagents are required for different doping tests. After determining the reagent based on the sample testing items in the experimental vessel, robot 4 moves the experimental vessel to the peristaltic pump connected to the reagent, thereby adding the corresponding reagent to the experimental vessel at the reagent addition position.

[0088] Peristaltic pumps can provide precise flow rates, ensuring that reagents added to experimental vessels are added in the preset dosage. Furthermore, the flow rate control of peristaltic pumps is relatively stable, and the start and stop of the peristaltic pump can be controlled according to experimental requirements.

[0089] In some embodiments, the reagent addition component 3 of this embodiment further includes an alarm and a liquid level sensor.

[0090] The liquid level sensor is used to detect the liquid level in the reagent tank. The liquid level sensor is connected to an alarm, which is used to sound an alarm when the liquid level in the reagent tank is too low.

[0091] The liquid level sensor can issue an alarm when the liquid level in the reagent tank is low, reminding staff to replenish the reagent in time. This avoids the experimental results of doping tests being affected by the lack of reagent. In addition, the automatic alarm eliminates the need for staff to constantly monitor whether the reagent bottle needs to be replenished, reducing the workload of the staff.

[0092] The alarm can be a buzzer, which sounds an alarm when the reagent level in the container is low. Alternatively, it can be an audible and visual alarm, which sounds both an audible alarm and a visual alarm when the reagent level in the container is low.

[0093] In some embodiments, such as Figure 1 and Figure 2 As shown, the visual inspection component 5 in this embodiment includes a bracket 51, a camera module 52, and a background plate 53.

[0094] The camera module 52 and the background plate 53 are both mounted on the bracket 51. A testing station is provided between the camera module 52 and the background plate 53. The testing station is equipped with a positioning groove for accommodating experimental vessels.

[0095] The testing station is used to place experimental vessels. The camera module 52 takes pictures of the liquid in the experimental vessels and compares them with the stored standard sample to determine whether the impurities in the liquid exceed the standard.

[0096] Background panel 53 provides an undisturbed background, resulting in a cleaner image of the liquid in the experimental vessel. Furthermore, when comparing the photos, the clean background makes the shape and color of the liquid stand out more, enhancing the overall image quality.

[0097] Specifically, the positioning groove can use a transparent support structure to allow the camera module 52 to clearly capture the liquid inside the experimental vessel. The testing station has a positioning bracket with two positioning plates along its height. The upper positioning plate has a positioning groove with a through hole at the bottom. The test tube can be inserted through the through hole and rest against the lower positioning plate, thus standing upright at the testing station. When the experimental vessel is a petri dish, it is placed in the positioning groove on the upper positioning plate.

[0098] In some embodiments, such as Figure 2 As shown, the height and / or angle of the camera module 52 relative to the bracket 51 in this embodiment are adjustable.

[0099] The camera module 52 is mounted on the bracket 51 through an adjustment structure. During the initial installation and debugging, the height and angle of the camera module 52 can be adjusted so that the camera module 52 can capture the sample to be tested placed on the positioning groove, ensuring a good imaging effect of the liquid in the experimental vessel.

[0100] Specifically, the adjustment structure may include a clamp and an adjusting nut. The camera module 52 is mounted on the bracket 51 via the clamp, and the height of the camera module 52 is adjusted by adjusting the height of the clamp on the bracket 51. The adjusting nut is threadedly connected to the clamp, and the angle of the camera module 52 is adjusted by rotating the adjusting nut. It is understandable that the adjustment structure can only assist in adjusting the height of the camera module 52, or it can only assist in adjusting the angle of the camera module 52.

[0101] In some embodiments, the laboratory glassware placement area 11 is used only for placing clean laboratory glassware. Specifically, the raw milk adulteration detection device also includes a cleaner. After the laboratory glassware that has undergone visual inspection is cleaned by the cleaner, it is placed back into the laboratory glassware placement area 11 by the robot 4. The cleaner is either an ultrasonic cleaner or a water washing device. Optionally, the cleaner has a drying function to prevent water droplets from dripping onto the laboratory glassware during the transfer process by the robot 4.

[0102] In some embodiments, such as Figure 1 As shown, the experimental vessel placement area 11 in this embodiment is divided into a first partition and a second partition.

[0103] The first section is used to hold clean laboratory glassware, and the second section is used to hold laboratory glassware that has undergone visual inspection. When the laboratory glassware includes both test tubes and plates, the first section is divided into a test tube area and a plate area, and the second section is similarly divided into a test tube area and a plate area. The test tube areas in the first section and the test tube areas in the second section are adjacent and arranged parallel to each other.

[0104] The experimental vessel placement area 11 in this embodiment can hold both clean and contaminated experimental vessels.

[0105] The mobile robot moving between the workstations places clean experimental vessels into the first section, and robot 4 places experimental vessels that have completed visual inspection into the second section, waiting for the mobile robot to collect and process the contaminated experimental vessels.

[0106] The main types of detection performed in the raw milk adulteration detection device of this embodiment include: alcohol test, 5% alcohol test, alkali, nitrite, phosphate and calcium chloride.

[0107] In alcohol tests and 5% alcohol tests, petri dishes are used to hold the samples and reagents.

[0108] In the alkali test, test tubes are used to hold the samples and reagents, and a mixing device is used to mix them.

[0109] In the nitrite test, the sample and reagent are placed in test tubes and mixed using a mixing device.

[0110] In the phosphate test, the sample and reagents are placed in a test tube and mixed using a mixing device. The mixture is then heated using a water bath heating element 27. After heating, the mixture is mixed again using a mixing device. After mixing, the mixture is allowed to stand. After standing, the liquid is poured from the test tube into a petri dish, and the liquid in the petri dish is visually inspected.

[0111] In the calcium chloride test, the sample and reagents are placed in a test tube and mixed using a mixing device. The mixture is then heated using a water bath heating element 27. After heating, the mixture is mixed again using a mixing device. After mixing, the mixture is allowed to stand. After standing, the liquid is poured from the test tube into a petri dish, and the liquid in the petri dish is visually inspected.

[0112] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
