Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0031] In the description of the embodiments of this utility model, it should be noted that, unless otherwise expressly specified and limited, the terms "first" and "second" are numbered for the purpose of clearly identifying product components and do not represent any substantial difference. The terms "installed," "connected," and "linked" should be interpreted broadly; for example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this utility model according to the specific circumstances. Furthermore, "multiple" means two or more.

[0032] The following is combined with Figures 1-3 This invention describes a dairy product testing device.

[0033] like Figure 1 As shown, the dairy product testing device provided in this embodiment includes a testing platform 1, a test tube rack 2, a reagent adding mechanism 3, a mixing mechanism 4, and a robot 5. The testing platform 1 has a sample placement area 11 and a vessel placement area 12. The test tube rack 2 is placed on the testing platform 1 and has multiple slots suitable for inserting test tubes 6. The reagent adding mechanism 3 has multiple outlets, each corresponding to a slot on the test tube rack 2. The mixing mechanism 4 has a placement position 41 suitable for placing the test tube rack 2. The robot 5 is used to pick up multiple test tubes 6 from the vessel placement area 12 and insert them into the slots of the test tube rack 2; to extract samples from the sample placement area 11 and add them to the multiple test tubes 6 on the test tube rack 2; and to transfer the test tube rack 2 containing the multiple test tubes 6 to the reagent adding mechanism 3 and the mixing mechanism 4.

[0034] The mixing mechanism 4 is used to simultaneously mix the samples and test reagents in multiple test tubes 6 on the test tube rack 2. The reagent adding mechanism 3 is used to simultaneously add test reagents to multiple test tubes 6 on the test tube rack 2. The multiple outlets of the reagent adding mechanism 3 correspond to different test items, and the multiple slots on the test tube rack 2 correspond one-to-one with the multiple outlets of the reagent adding mechanism 3, so that the multiple test tubes 6 inserted on the test tube rack 2 can correspond one-to-one with the multiple outlets.

[0035] The testing station 1 has a test tube rack placement area, and test tube rack 2 is placed in the test tube rack placement area. Robot 5 is equipped with a robotic arm, the end of which can move between the sample placement area 11 and the test tube placement area, enabling the robot to pick up test tubes 6 from the glassware placement area 12 and insert them into the test tube rack 2. The end of the robotic arm can also move from the test tube rack placement area to the reagent adding mechanism 3, enabling the robot to transfer the test tube rack 2 to the reagent adding mechanism 3 and simultaneously add reagents to multiple test tubes 6 containing samples on the test tube rack 2. The end of the robotic arm can also move from the reagent adding mechanism 3 to the mixing mechanism 4, enabling the robot to transfer the test tube rack 2 to the mixing mechanism 4 and simultaneously mix the samples and reagents in the multiple test tubes 6 on the test tube rack 2.

[0036] The dairy product testing device also includes a testing mechanism 7, which is used for visual sensory inspection of the mixture of sample and reagent in the test tube. The testing mechanism 7 is equipped with an imaging module and a recognition module, which can photograph and record the liquid in the test tube 6, and determine the state of the sample through the recognition module.

[0037] Optionally, such as Figure 1 As shown, the reagent adding mechanism 3, mixing mechanism 4, robot 5, and detection mechanism 7 are all mounted on the detection platform 1. Alternatively, the reagent adding mechanism 3, mixing mechanism 4, robot 5, and detection mechanism 7 can be located on the side of the detection platform 1 and set up independently of it. When robot 5 is set up independently of the detection platform 1, robot 5 can be a mobile robot to achieve a greater range of motion.

[0038] The steps for sample testing using this dairy product testing device are as follows: Robot 5 picks up multiple test tubes 6 from the container placement area 12 according to the number of items to be tested for the corresponding sample, and transfers these test tubes 6 to the test tube rack 2, inserting them into multiple slots on the rack 2. Robot 5 picks up samples from the sample placement area 11 and adds them sequentially to the multiple test tubes 6 on the test tube rack 2. Robot 5 then moves the test tube rack 2, after adding the samples, to the reagent adding mechanism 3, aligning the multiple test tubes 6 on the rack 2 with the multiple liquid outlets of the reagent adding mechanism 3, and simultaneously adds test reagents to the multiple test tubes 6. Robot 5 then moves the test tube rack 2, after adding the reagents, to the mixing mechanism 4, where the sample and test reagents in the multiple test tubes 6 on the rack 2 are simultaneously mixed. Finally, Robot 5 moves the mixed test tubes to the testing mechanism 7 for testing.

[0039] The dairy product testing device provided in this embodiment of the invention features a test tube rack 2 with multiple outlets on the reagent adding mechanism 3 corresponding to multiple slots on the test tube rack 2. During testing, a robot 5 picks up multiple test tubes 6 from the container placement area 12 and inserts them into the slots on the test tube rack 2, adding the same sample to each test tube 6. The robot 5 then moves the test tube rack 2 to the reagent adding mechanism 3, simultaneously adding reagents to the multiple test tubes 6. Finally, the robot 5 moves the test tube rack 2 to the mixing mechanism 4, simultaneously mixing the samples and reagents in the multiple test tubes 6. Compared to traditional testing methods that rely on manual handling of multiple test items, this device significantly improves testing efficiency and reduces the workload of personnel.

[0040] In this embodiment of the invention, the execution end of the robot 5 is provided with a picking mechanism 52, which is used to pick up test tubes 6 and test tube rack 2. That is, the picking mechanism 52 picks up multiple test tubes 6 from the container placement area 12 and inserts the multiple test tubes 6 into the multiple slots on the test tube rack 2; the picking mechanism 52 picks up the test tube rack 2 loaded with multiple test tubes 6 and places the test tube rack 2 into the reagent adding mechanism 3 and the mixing mechanism 4.

[0041] In this embodiment of the invention, the robot 5 includes a robotic arm 51, a picking mechanism 52, and a control module. The picking mechanism 52 is disposed at the end of the robotic arm 51, and both the robotic arm 51 and the picking mechanism 52 are communicatively connected to the control module. The control module is used to control the robotic arm 51 to move the picking mechanism 52 between the reagent adding mechanism 3 and the mixing mechanism 4, and to control the picking mechanism 52 to pick up the test tube 6 and the test tube rack 2.

[0042] The robotic arm 51 is used to drive the picking mechanism 52 to move in three-dimensional space. The position of the picking mechanism 52 can be flexibly adjusted under the control of the control module. The robotic arm 51 can be a multi-joint robotic arm, a Cartesian coordinate system robotic arm, or a cylindrical coordinate system robotic arm, etc.

[0043] The dairy product testing device provided in this embodiment of the present invention also includes a pipette 53, which is disposed at the end of the robotic arm 51. The control module is also used to control the robotic arm 51 to drive the pipette 53 to pick up the sample from the sample placement area 11 and add the sample to multiple test tubes 6 on the test tube rack 2.

[0044] Specifically, the pipette 53 includes a pipette and a pipette tip. The pipette is mounted at the end of the robotic arm 51. A first placement rack 13 is provided on the detection stage 1, which houses multiple pipette tips of different sizes. The control module can control the robotic arm 51 to assemble the pipette with one of the pipette tips. After assembly, the control module controls the robotic arm 51 to move the pipette tip to the sample placement area 11 to aspirate the sample, and then move it to the test tube rack 2 to release the aspirated sample into multiple test tubes 6 on the test tube rack 2.

[0045] The pipette tip is placed vertically on the first placement frame 13. Specifically, the first placement frame 13 has multiple insertion holes, and the pipette tip is vertically inserted into the insertion holes. The robotic arm 51 drives the pipette to press the pipette tip downwards, thus assembling the pipette and the tip. To buffer the downward picking pressure of the pipette tip, 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 is subjected to vertical pressure, thus preventing damage to the tip.

[0046] Furthermore, if Figure 1 As shown, the testing stage 1 is equipped with a waste tray 8, which is used to hold discarded pipette tips. After sample collection is completed, the robotic arm 51 removes the discarded pipette tips and places them into the waste tray, so that clean pipette tips can be assembled for the next sample collection. Specifically, the pipette is equipped with a release button. After the pipette tip picks up the sample, the robotic arm 51 triggers the release button to remove the pipette tip from the pipette.

[0047] The dairy product testing device provided in this embodiment of the present invention also includes a vision module. The vision module is communicatively connected to the control module and is used to acquire image information of the sample placement area 11 and the identification code on the sample packaging. The control module is also used to determine the start of the testing task based on the image information, determine the testing items based on the identification code, determine the number of test tubes 6 that need to be transferred from the container placement area 12 to the test tube rack 2 based on the testing items, and control the robotic arm 51 to drive the pipette 53 to pick up the sample from the sample placement area 11 and add it to the multiple test tubes 6 on the test tube rack 2.

[0048] The pipette can be fixedly connected to the robotic arm 51. The pipette is communicatively connected to the control module, which controls and adjusts the pipette's volume. The pipette can also be detachably connected to the robotic arm 51. The storage rack also holds multiple pipettes of different sizes. The control module can control the pick-up mechanism 52 to pick up the required size pipette and assemble it with the corresponding tip.

[0049] When a sample is placed in the sample placement area 11, the vision module of robot 5 acquires image information of the sample, triggering detection. The control module then initiates the detection task based on this image information. The control module controls the robotic arm 51 to move the picking mechanism 52 to the sample placement area 11 to pick up the sample. The vision module acquires the identification code on the sample packaging, identifies the code, and then places the sample back in the sample placement area 11. The control module obtains the corresponding sample information based on the identification code, including the sample number and its corresponding multiple detection items.

[0050] For example, if the control module determines that there are 5 different testing items based on the identification code, then it determines that 5 test tubes 6 are needed. The control module controls the robotic arm 51 to drive the picking mechanism 52 to pick up 5 test tubes 6 sequentially from the container placement area 12, and inserts the 5 test tubes 6 into the corresponding slots on the test tube rack 2. Then, the control module controls the robotic arm 51 to drive the pipette 53 to draw samples from the sample placement area 11 and add them to these 5 test tubes 6.

[0051] Optionally, the vision module is also used to acquire image information of the test tube rack 2. The control module accurately controls the robotic arm 51 to move the pipette 53 between the sample placement area 11 and the test tube rack 2 to perform sample aspiration based on the image information of the sample placement area 11 and the test tube rack 2. The vision module is also used to acquire image information of the glassware placement area 12, the reagent addition mechanism 3, and the mixing mechanism 4. The control module controls the picking mechanism 52 and the robotic arm 51 to accurately pick up and transfer the test tube 6 and the test tube rack 2 based on the corresponding image information.

[0052] In some embodiments of this utility model, the reagent adding mechanism 3 and the mixing mechanism 4 are respectively connected to the control module for communication.

[0053] Robot 5 moves test tube rack 2 to reagent adding mechanism 3, aligning multiple test tubes 6 on test tube rack 2 with multiple liquid outlets of reagent adding mechanism 3. Then, the control module activates reagent adding mechanism 3 to simultaneously add reagents to the multiple test tubes 6 on test tube rack 2. After reagent addition is complete, robot 5 moves test tube rack 2 to mixing mechanism 4, and the control module activates mixing mechanism 4 to simultaneously mix the multiple test tubes 6 on test tube rack 2.

[0054] The control module can determine the reagent addition amount based on the detection items, and control the flow rate of the reagent addition mechanism 3 based on the reagent addition amount. The control module can also determine the mixing parameters based on the detection items, and control the vibration amplitude and frequency of the mixing mechanism 4 based on the mixing parameters.

[0055] In this embodiment of the present invention, the test tube rack 2 includes a first frame 21 and a second frame 22. The first frame 21 and the second frame 22 are fixedly connected and spaced apart in the vertical direction. The second frame 22 is located above the first frame 21. The slot passes through the second frame 22, and the bottom of the slot is located on the first frame 21.

[0056] Specifically, the test tube rack 2 also includes multiple vertically arranged connecting brackets. The upper end of the connecting bracket is fixedly connected to the second frame 22, and the lower end is fixedly connected to the first frame 21. The first frame 21 has multiple grooves on the side facing the second frame 22, and the second frame 22 has multiple through holes. The multiple through holes and multiple grooves are arranged one-to-one to form multiple slots. When the test tube 6 is inserted into the slot, the test tube 6 is inserted into the through hole and the bottom of the test tube 6 is located in the groove.

[0057] Furthermore, the height of the second frame 22 relative to the first frame 21 is greater than half the height of the test tube 6, so that the test tube 6 can be stably inserted into the test tube rack 2, preventing multiple test tubes 6 from tipping over when being mixed on the mixing mechanism 4.

[0058] In some embodiments of this utility model, the picking mechanism 52 includes a driving member, a first gripper 521 and a second gripper 522. The driving member is connected to the first gripper 521 and the second gripper 522 so that the first gripper 521 and the second gripper 522 can move closer to or further away from each other.

[0059] Specifically, the first gripper 521 and the second gripper 522 are connected to the end of the robotic arm 51. One end of the first gripper and one end of the second gripper are respectively connected to the driving component. Under the action of the driving component, the other end of the first gripper 521 and the other end of the second gripper 522 can move closer or further away from each other, thereby realizing the picking and releasing action of the test tube 6 or the test tube rack 2.

[0060] Furthermore, the clamping surfaces of the first gripper 521 and the second gripper 522 are arranged opposite to each other, and a limiting groove is provided on the clamping surface, which is suitable for limiting and engaging with the edge of the second frame 22.

[0061] Specifically, the second frame 22 is a rectangular plate. The width of the limiting groove is adapted to the thickness of the edge of the second frame 22, so that the edge of the second frame 22 can be confined within the limiting groove. When the picking mechanism 52 grasps the test tube rack 2, the limiting groove on the clamping surface of the first gripper 521 is engaged with one side edge of the second frame 22, and the limiting groove on the clamping surface of the second gripper 522 is engaged with the other side edge of the second frame 22, so that the test tube rack 2 can be grasped stably.

[0062] Optionally, the limiting groove also engages with the test tube 6 for limiting. That is, the width of the limiting groove is also adapted to the diameter of the test tube 6, so that the test tube 6 can also be confined within the limiting groove. This increases the contact area between the test tube 6 and the clamping surface, thereby achieving stable gripping of the test tube 6.

[0063] Optionally, the limiting groove includes a first limiting groove and a second limiting groove, which are arranged to cross each other, and both the first limiting groove and the second limiting groove are suitable for edge limiting engagement with the second frame 22.

[0064] When the picking mechanism 52 grasps the test tube rack 2, the first limiting groove on the clamping surface of the first gripper 521 can be engaged with one side edge of the second frame 22, and the first limiting groove on the clamping surface of the second gripper 522 can be engaged with the other side edge of the second frame 22. Alternatively, the second limiting groove on the clamping surface of the first gripper 521 can be engaged with one side edge of the second frame 22, and the second limiting groove on the clamping surface of the second gripper 522 can be engaged with the other side edge of the second frame 22.

[0065] In this embodiment, the picking mechanism 52 can select either the first limiting groove or the second limiting groove to cooperate with the second frame 22 during the picking operation, which improves the stability of the picking mechanism 52 in grasping the test tube rack 2, and also improves the flexibility of the picking mechanism 52.

[0066] As a specific example, the first limiting groove and the second limiting groove are set perpendicular to each other.

[0067] In some embodiments of this utility model, the placement position 41 is provided with a positioning groove, which is suitable for limiting and cooperating with the first frame 21.

[0068] Specifically, the mixing mechanism 4 has a vibrating end located at the top of the mixing mechanism 4, and the placement position 41 is located at the vibrating end. The shape and size of the positioning groove are adapted to the shape and size of the first frame 21, so that the first frame 21 can be confined within the positioning groove, preventing the test tube rack 2 from moving or tipping over due to vibration during the mixing operation.

[0069] Optionally, the mixing mechanism 4 is a vortex oscillator.

[0070] In some embodiments of this invention, the reagent adding mechanism 3 includes a peristaltic pump and multiple reagent tanks 31. Multiple peristaltic pumps can be connected one-to-one with multiple reagent tanks 31, and each peristaltic pump has an outlet. Alternatively, there can be a single peristaltic pump, which is a multi-channel peristaltic pump with multiple channels independently configured and corresponding to multiple outlets. The peristaltic pump allows for precise flow control and relatively stable flow control, enabling the pump to be started and stopped according to experimental requirements, thus achieving the addition of reagents according to a preset dosage.

[0071] Specifically, the peristaltic pumps are connected to reagent containers 31 via pipes, and different reagent containers 31 contain different reagents. A second shelf 14 is located below the testing platform 1, on which multiple reagent containers 31 are arranged, saving space on the platform. A stand is also provided on the testing platform 1, on which multiple peristaltic pumps are mounted, and the lower side of the stand forms a reagent adding position. The robot 5 moves the test tube rack 2 to this reagent adding position, so that the openings of multiple test tubes 6 on the test tube rack 2 are aligned with the multiple outlets of the multiple peristaltic pumps.

[0072] 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.
