[0004] In the process of implementing the embodiments of this disclosure, at least the following problems were found in the related art:

[0005] In related technologies, the cost of microbial sample pretreatment systems is high because they require multiple automated devices. Furthermore, these systems are limited to streaking petri dishes, offering only basic functionality and low cost-effectiveness.

[0006] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0007] To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not intended as a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these embodiments, but rather as a prelude to the detailed description that follows.

[0008] This disclosure provides a microbial sample pretreatment system to improve the functional diversity and cost-effectiveness of the microbial sample pretreatment system.

[0009] This disclosure provides a microbial sample pretreatment system, comprising: a workbench defining a first region, a second region, and a third region arranged side-by-side; a sample processing assembly located in the first region, including a sample loading device and a sample transfer device, wherein the sample loading device is used to place a sample container holding the sample, and the sample transfer device is used to transfer the sample container between the first region and the second region; a streaking assembly located in the second region, including a petri dish loading device, a slide loading device, an inoculation device, and a streaking device, wherein the inoculation device and the streaking device are used to streak the petri dish and / or to smear the slide; and a sample receiving assembly located in the third region, including a petri dish receiving device and a slide receiving device, wherein the petri dish receiving device is used to receive the streaked petri dish, and the slide receiving device is used to receive the smeared slide.

[0010] The microbial sample pretreatment system provided in this disclosure can achieve the following technical effects:

[0011] The workbench is divided into three parallel zones: a first zone, a second zone, and a third zone. The sample processing component, the streaking component, and the sample receiving component are located within these zones, respectively. This allows users to sequentially observe the sample processing, reducing the need for back-and-forth observation and minimizing operational disruptions. Furthermore, the zoning prevents contamination between zones during sample processing. The sample processing component is located in the first zone. During operation, the sample container containing the sample is first placed in the sample loading device in the first zone. Then, the sample transfer device transfers the processed sample container to the second zone for sample extraction, and finally transfers the extracted sample container back to the first zone, thus achieving sample transfer between the two zones. The streaking component is located in the second zone. After the sample transfer device transfers the sample from the first zone to the second zone, the inoculation device extracts the sample. Simultaneously, the petri dish loading device or slide loading device transfers the petri dish or slide to the streaking device. The inoculation device and the streaking device then work together to streak the petri dish or smear the slide. After streaking, the culture dish or the smeared slide can be transferred to the third area. Then, the culture dish collection device and the slide collection device collect the culture dish or slide respectively, thus realizing the entire sample pretreatment process.

[0012] The microbial sample pretreatment system provided in this disclosure integrates sample processing, petri dish streaking, and slide smearing onto a single platform, which better aligns with actual clinical microbiology testing procedures. Furthermore, this system can perform both petri dish streaking and slide smearing, increasing the functionality of the pretreatment system and improving its cost-effectiveness.

[0037] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0038] For ease of description, the front-back, left-right and right directions of this application are as follows: Figure 1 As shown.

[0039] Combination Figures 1 to 14 As shown, this disclosure provides a microbial sample pretreatment system (hereinafter referred to as the system), which includes a workbench 100, a sample processing component 10, a streak smear component 20, and a sample collection component 30, as follows. Figure 1 As shown, the workbench 100 defines a first area 101, a second area 102, and a third area 103 arranged side by side.

[0040] like Figure 1 As shown, the sample processing component 10 is located in the first region 101. The sample processing component 10 includes a sample loading device 11 and a sample transfer device 17. The sample loading device 11 is used to place a sample container holding the sample, and the sample transfer device 17 is used to transfer the sample container between the first region 101 and the second region 102. The streaking smear component 20 is located in the second region 102. The streaking smear component 20 includes a petri dish loading device 21, a slide loading device 22, an inoculation device 50, and a streaking smear device 23. The inoculation device 50 and the streaking smear device 23 are used to streak the petri dish 40 and / or to smear the slide. The sample receiving component 30 is located in the third region 103. The sample receiving component 30 includes a petri dish receiving device 31 and a slide receiving device 32. The petri dish receiving device 31 is used to receive the streaked petri dish 40, and the slide receiving device 32 is used to receive the smeared slide.

[0041] In this embodiment, the workbench 100 defines a first region 101, a second region 102, and a third region 103. The sample processing component 10, the streaking smear component 20, and the sample receiving component 30 are located in the three regions respectively. This division of the system components according to function avoids contamination between regions and interference between operational processes during sample processing. Furthermore, the first region 101, the second region 102, and the third region are arranged side-by-side, facilitating user operation and observation during sample processing without requiring the user to move around, and also preventing mutual interference between preceding and following processes.

[0042] Optionally, the first region 101, the second region 102, and the third region 103 are arranged side by side along the length or width of the worktable 100. Alternatively, the first region 101, the second region 102, and the third region 103 are arranged side by side along a diagonal direction of the worktable 100. In practical applications, the first region 101, the second region 102, and the third region 103 can be configured according to the size and shape of the worktable 100, or according to the user's usage habits.

[0043] The system is functionally divided into a sample processing component 10, a streaking and smearing component 20, and a sample collection component 30. The sample processing component 10 processes samples. When the system starts working, a sample container containing the sample is placed in the sample loading device 11. The sample container, either directly or after a series of processing steps, is transferred to the second area 102 via the sample transfer device 17, facilitating sample extraction by the inoculation device 50. After sample extraction, the sample container is returned to the first area 101 via the sample transfer device 17 for recycling. After the sample transfer device 17 transfers the sample container to the second area 102, the inoculation device 50 extracts the sample from the container. Then, depending on the sample processing requirements, the sample is either loaded onto a culture dish 40 via the culture dish loading device 21 or onto a glass slide via the slide loading device 22. After the culture dish 40 or the glass slide is placed on the streaking and smearing device 23, the inoculation device 50 streaks the extracted sample onto the culture dish 40 or smears it onto the glass slide. After streaking, the culture dish 40 or the slide after smearing is transferred to the third region 103. The sample receiving component 30 in the third region 103 collects the streaked culture dish 40 or the slide after smearing for further processing.

[0044] In this embodiment of the disclosure, the system integrates sample processing, streaking of culture dishes, and smearing of glass slides onto the same platform, which increases the functionality of the system and improves its cost-effectiveness.

[0045] Optionally, the system also includes a controller, which is electrically connected to the sample processing component 10, the streaking smear component 20 and the sample collection component 30, and the controller is capable of controlling the operation of multiple components of the system.

[0046] Optionally, such as Figure 1 , 2 and Figure 7 As shown, the streak plate device 23 includes a tray 231, which is movably disposed on one side of the inoculation device 50. The tray 231 can cooperate with the culture dish loading device 21 or the slide loading device 22 to support the culture dish 40 or the slide.

[0047] In this embodiment of the present disclosure, the streaking and smearing device 23 includes a tray 231, which can hold both the culture dish 40 and the glass slide. This allows the culture dish 40 or the glass slide to be placed in the tray 23 according to the processing requirements. The tray 23 is then used in conjunction with the inoculation device 50 for streaking or smearing. In this way, both the glass slide and the culture dish 40 can be used with the inoculation device 50, which improves the versatility and ease of use of the system.

[0048] Optionally, the scribing device 23 also includes an operating table 24, which is movably disposed on the workbench 100, and a tray 231 is rotatably disposed above the operating table 24; wherein, the upper wall of the tray 231 is constructed with a petri dish loading groove 2316 and a slide loading groove 2312, the slide loading groove 2312 being located inside the petri dish loading groove 2316, the petri dish loading groove 2316 being used to load petri dishes 40, and the slide loading groove 2312 being used to load slides.

[0049] In this embodiment, the operating table 24 is movably disposed on the workbench 100, so that the operating table 24 can drive the tray 231 to move relative to the workbench 100. The tray 231 is rotatably disposed above the operating table 24, so that the tray 231 can also rotate relative to the operating table 24, making the movement of the tray 231 more flexible, thereby improving the flexibility of scribing or smearing to meet the scribing and smearing needs of different culture dishes 40 or glass slides.

[0050] Optionally, the operating table 24 is slidably connected to the worktable 100. Specifically, the operating table 24 can move relative to the worktable 100 in the left-right and front-back directions, and the tray 231 can drive the petri dish 40 or the glass slide to translate or rotate, thereby improving the flexibility of the tray 231 and improving the scribing or smearing effect.

[0051] Optionally, the tray 231 includes a first reinforcing rib 2311, a second reinforcing rib 2313, a third reinforcing rib 2314, and a fourth reinforcing rib 2315. The upper wall portion of the first reinforcing rib 2311 is recessed to form a slide loading groove 2312. The second reinforcing rib 2313 is arranged intersecting with the first reinforcing rib 2311 and connected to the middle portion of the first reinforcing rib 2311. The third reinforcing rib 2314 is connected to one end of the first reinforcing rib 2311. The fourth reinforcing rib 2315 is connected to the other end of the first reinforcing rib 2311. The second reinforcing rib 2313, the third reinforcing rib 2314, and the fourth reinforcing rib 2315 define a petri dish loading groove 2316.

[0052] In this embodiment, the upper wall of the first reinforcing rib 2311 is recessed to form a slide loading groove 2312, which is used to place slides to achieve stable slide positioning and operation. The shape and size of the slide loading groove 2312 match the shape and size of the slide to improve the stability of slide placement. A second reinforcing rib 2313 is cross-connected to the middle of the first reinforcing rib 2311, and a third reinforcing rib 2314 and a fourth reinforcing rib 2315 are located at both ends of the first reinforcing rib 2311. Thus, the first reinforcing rib 2311, the second reinforcing rib 2313, the third reinforcing rib 2314, and the fourth reinforcing rib 2315 increase the cross-sectional area of ​​the tray 231, thereby defining the culture dish loading groove 2316. The shape and size of the culture dish loading groove 2316 match the shape and size of the culture dish 40 to achieve stable loading and operation of the culture dish 40. The tray 231 of this embodiment can hold both the culture dish 40 and the glass slide, thus enabling the system to perform streaking on the culture dish 40 and smearing on the glass slide without the need for multiple trays 231, thereby improving operational efficiency.

[0053] In addition, during the microbial testing process, the streaking of the petri dish 40 and the smearing of the slide are not performed simultaneously. Therefore, the reusable tray 231 of this application can be used for different testing processes. The tray 231 can be rotated and translated, so that the tray 231 can meet the various inoculation needs of the petri dish 40 or the slide, thus increasing its functionality.

[0054] Optionally, the length direction of the slide loading groove 2312 is consistent with the length direction of the first reinforcing rib 2311, and the second reinforcing rib 2313, the third reinforcing rib 2314, and the fourth reinforcing rib 2315 are spaced apart along the length direction of the first reinforcing rib 2311. In this way, the tray 231 is not a completely solid structure, and a clamping groove 2317 is formed between adjacent reinforcing ribs. The tray 231 has a reserved clamping groove 2317 to make room so that when the culture dish 40 is placed on the tray 231 or removed from the tray 231, the clamp for transferring the culture dish 40 can be inserted into the clamping groove 2317 to improve the clamping stability of the culture dish 40.

[0055] Optionally, the streaking device 23 also includes a positioning pin 2318, which protrudes from the outside of the culture dish loading groove 2316. When the culture dish 40 is loaded into the culture dish loading groove 2316, the positioning pin 2318 positions the culture dish 40 to prevent it from shifting.

[0056] Optionally, there are multiple positioning pins 2318, which are arranged sequentially and at intervals along the circumference of the culture dish loading groove 2316 to improve the limiting effect on the culture dish in more than 40 directions.

[0057] For example, such as Figure 7 As shown, multiple positioning pins 2318 are respectively located on the second reinforcing rib, the third reinforcing rib, and the fourth reinforcing rib.

[0058] Optionally, the petri dish 40 includes a petri dish housing 42 and a petri dish lid 41, with the lid 41 covering the top of the petri dish housing 42. The petri dish 40 has a circular cross-section.

[0059] Optionally, the culture dish 40 has a diameter of 90 mm and a thickness of 15 mm. The culture dish 40 is made of transparent plastic and is filled with agar medium.

[0060] Optionally, the slide is made of glass, is rectangular, and has a size of 75mm*25mm.

[0061] Optionally, the streaking device 23 also includes a capping device, which is rotatably positioned above the tray 231. When the culture dish 40 is loaded on the tray 231, the capping device can open the culture dish cap 41 so that the inoculation device 50 can streak the culture medium in the culture dish 40.

[0062] Optionally, the opening device includes a fixed base, an opening robotic arm, and an adsorption device. The fixed base is installed on the worktable 100, one end of the opening robotic arm is rotatably mounted on the fixed base, and the other end of the opening robotic arm is provided with an adsorption device. The adsorption device can adsorb and transfer the petri dish lid 41 to open or close the petri dish 40.

[0063] Optionally, the opening device is located on the side of the tray 231 facing the third region 103.

[0064] Optional, such as Figure 5 As shown, the slide loading device 22 includes a sample dispensing device 221 and a first push rod 222. The sample dispensing device 221 is vertically mounted on the worktable 100. The sample dispensing device 221 has a first storage compartment arranged side by side in a vertical direction. The first storage compartment is used to place the slide. The first push rod 222 is located on one side of the sample dispensing device 221 and is used to push the slide out of the first storage compartment. The worktable 100 is constructed with a slide rail. The scribing and smearing device 23 is slidably mounted on the slide rail. The scribing and smearing device 23 can move along the slide rail to the other side of the sample dispensing device 221 to carry the slide pushed out from the first storage compartment.

[0065] In this embodiment, the sample dispensing device 221 has a first storage compartment arranged side by side in a vertical direction. Glass slides are placed in the first storage compartment, and all glass slides to be smeared are stored within the sample dispensing device 221. A first push rod 222 is located on the side of the first storage compartment opposite to the scribing smearing device 23. The first push rod 222 can push the glass slides out of the first storage compartment, facilitating their transfer to the tray 231 of the scribing smearing device 23. The scribing smearing device 23 can move along a slide to the other side of the sample dispensing device 221 and come into contact with it. The first push rod 222 then pushes the glass slides to be smeared onto the tray 231 from one side of the sample dispensing device 221. The scribing smearing device 23 then returns along the slide to the preset inoculation position (the position where the tray can cooperate with the inoculation loop for scribing or smearing), facilitating smearing in conjunction with the inoculation device 50. In addition, the sample dispensing device 221 is vertically mounted on the worktable 100, so that when the glass slide corresponding to the first push rod 222 is pushed out, the height of the sample dispensing device 221 can be adjusted so that the first push rod 222 corresponds to the first storage compartment with the glass slide.

[0066] Optionally, the first push rod 222 is driven by a first push rod 222 drive device, which can drive the first push rod 222 to extend or retract.

[0067] Optionally, the slide loading device 22 further includes a first lifting mechanism, which is located at the bottom of the sample dispensing device 221 and is used to raise and lower the sample dispensing device 221.

[0068] For example, the first lifting mechanism can be a screw and nut structure or an electric push rod, etc.

[0069] Optionally, such as Figure 1 and Figure 2 As shown, the slide loading device 22 is located in front of the inoculation device 50, which facilitates the user to load slides onto the slide loading device 22 from the front of the worktable 100. The slide extends in the front-back direction, from the preset inoculation position to one side of the loading device, so that the streaking device 23 can move between the preset inoculation position and the slide loading device 22.

[0070] Optionally, such as Figure 4As shown, the culture dish loading device 21 includes an operating platform 211, a storage chamber 212, and a gripper assembly. The operating platform 211 is rotatably mounted above the worktable 100. The storage chamber 212 is located above the operating platform 211 and extends vertically for placing the culture dish 40. A lifting mechanism (hereinafter referred to as the second lifting mechanism 213 for ease of description) is located at the bottom of the storage chamber 212 and can contact the culture dish 40 inside the storage chamber 212 for lifting the culture dish 40. The gripper assembly is located on one side of the operating platform 211 and includes a gripper 214 and a lifting and rotating mechanism 215. The gripper 214 is located above the storage chamber 212 and is used to grip the culture dish 40 and drive the culture dish 40 to move.

[0071] In this embodiment, the culture dish loading device 21 provides a culture dish 40 to be streaked to the streaking device 23. A storage chamber 212 holds the culture dish 40. A second lifting mechanism 213 is located at the bottom of the culture dish 40, enabling it to lift and lower the dish 40 to adjust its height. A gripper 214 is located above the storage chamber 212 and grips the culture dish 40 within the storage chamber 212, moving it to transfer it. A lifting and rotating mechanism 215 is connected to the gripper 214, allowing it to lift and rotate relative to the operating platform 211 to grasp, transfer, and place the culture dish 40. Furthermore, the culture dish loading device 21 of this embodiment eliminates manual operation in microbial testing, automating the selection, storage, and gripping of the culture dish 40, avoiding manual selection errors, and improving the efficiency of microbial testing.

[0072] Optionally, a storage chamber 212 can hold multiple culture dishes 40, which are stacked vertically within the storage chamber 212. When the upper culture dish 40 in the storage chamber 212 is grasped, the second lifting mechanism 213 can lift the remaining culture dishes 40 from the bottom, allowing the grippers 214 above to grasp them. After the culture dish 40 in the corresponding storage chamber 212 is grasped, the second lifting mechanism 213 can lower the remaining culture dishes 40 to prevent them from falling and to avoid affecting the rotation of the operating platform.

[0073] Optionally, the second lifting mechanism 213 can pass through the workbench 100 and the operating platform 211. When the second lifting mechanism 213 rises into the storage compartment 212, the second lifting mechanism 213 and the operating platform 211 are limited to restrict the rotation of the operating platform 211. When the second lifting mechanism 213 descends below the operating platform 24, the second lifting mechanism 213 and the operating platform 24 are released from the limit, and the operating platform 24 can rotate relative to the workbench 100.

[0074] In this embodiment, after the culture dish 40 in the corresponding storage chamber 212 is grasped, if it is necessary to grasp the culture dish 40 in another storage chamber 212, the controller controls the second lifting mechanism 213 to first drive the culture dish 40 in the storage chamber 212 that grasped the culture dish 40 to descend, and the second lifting mechanism 213 descends to below the operating platform 211, releasing the limit. Then, the controller controls the operating platform 211 to rotate so that the next target storage chamber 212 rotates to the position corresponding to the gripper 214. At this time, the controller controls the second lifting mechanism 213 to rise, lifting the culture dish 40 in the target storage chamber 212. The second lifting mechanism 213 can limit the operation platform 211 to prevent the operating platform 211 from rotating when the gripper 214 is working.

[0075] Optionally, there are multiple storage compartments 212, and the multiple storage compartments 212 are arranged sequentially at intervals along the circumference of the operating platform 211.

[0076] In this embodiment of the disclosure, the operating platform 211 is provided with multiple storage compartments 212, which can increase the storage capacity of the petri dishes 40 and also improve the stability of the operating platform 211. Optionally, the multiple storage compartments 212 can be the same in size and shape or different in shape. Optionally, the multiple storage compartments can hold the same type of petri dishes 40 or different types of petri dishes 40. In actual use, the type of petri dish 40 in each storage compartment 212 can be customized according to the usage requirements.

[0077] Optionally, multiple storage compartments 212 are arranged in a ring around the circumference of the operating platform 211, which can further improve the balance and stability of the operating platform 211.

[0078] Optionally, the culture dish loading device 21 further includes a position sensor 216, which detects the position of the culture dish 40. The position sensor 216 is electrically connected to the gripper assembly and the second lifting mechanism 213. When the second lifting mechanism 213 raises the culture dish 40 to a preset position, the gripper assembly picks up the culture dish 40 at the preset position. When there is no culture dish 40 at the preset position, the position sensor 216 transmits a signal to the second lifting mechanism 213, enabling the second lifting mechanism 213 to raise the culture dish 40.

[0079] In this embodiment, the position sensor 216 can sense the position of the culture dish 40 within the storage compartment 212. When no culture dish 40 is located at the preset position, the second lifting mechanism 213 can lift the culture dish 40. When the culture dish 40 moves to the preset position, the gripper assembly can grasp it, improving the ease of gripping the culture dish 40. The position sensor 216 enables automatic lifting and lowering of the culture dish 40, improving the efficiency of automatic gripping, avoiding manual selection errors, and increasing the efficiency of microbial testing.

[0080] Optionally, the position sensor 216 corresponds to the upper part of the storage compartment 212 so that the gripper 214 can grasp the culture dish 40.

[0081] Optionally, the culture dish loading device 21 also includes a support column located inside the multiple storage chambers 212, and a position sensor 216 is located on the support column, so that the position of the culture dish 40 in the multiple storage chambers 212 can be detected by a single position sensor 216.

[0082] Optionally, the operating platform 211 is rotatably mounted on the workbench 100, and the operating platform 211 can rotate around its axis, so that the multiple storage compartments 212 on the operating platform 211 can also rotate around the axis of the operating platform 211.

[0083] In this embodiment, since the gripper assembly is located on one side of the operating platform 211 and there are multiple storage chambers 212, the operating platform 211 can rotate, allowing each storage chamber 212 to rotate to a position corresponding to the gripper assembly, so that the gripper assembly can grasp the culture dish 40 from different storage chambers 212. Furthermore, the operating platform 211 rotates around its own axis, reducing the space occupied by the rotation of the operating platform 211. It also eliminates the need for the gripper assembly to rotate around the operating platform 211, reducing the space occupied by the culture dish loading device 21 and improving the system's structural compactness.

[0084] Optionally, the culture dish loading device 21 and the slide loading device 22 are arranged side by side, which facilitates the user to add culture dishes 40 to the culture dish loading device 21 and slides to the slide loading device 22. Specifically, the culture dish loading device 21 and the slide loading device 22 are located in front of the inoculation device 50.

[0085] Optionally, the culture dish loading device 21 and the slide loading device 22 are arranged along the direction from the first region 101 to the second region 102, and the distance between the streaking device 23 and the slide loading device 22 is smaller than the distance between the streaking device 23 and the culture dish loading device 21. Optionally, the streaking device 23 is located behind the slide loading device 22, and the culture dish loading device 21 is located to the left of the slide loading device 22. Here, since the streaking device 23 needs to move through a slide and cooperate with the slide loading device 22, while the culture dish loading device 21 can be transferred by the gripper 214, the distance between the streaking device 23 and the slide loading device 22 is smaller, which can save the length of the slide, avoid interference between different processes, and make the layout of each device of the streaking assembly 20 in the second region 102 more reasonable, conforming to the biological detection experimental process and improving sample processing efficiency.

[0086] Optionally, the gripper assembly is located between the operating platform 211 and the slide loading device 22 to reduce the distance the gripper 214 travels to the scribing device 23.

[0087] Optionally, the sample processing component includes a sample scanning device 15, which is located on one side of the sample loading device 11 and is used to identify the sample container. In this embodiment of the present disclosure, the sample scanning device 15 can identify the label of the sample container to facilitate the identification and recording of the sample contents.

[0088] Optionally, the sample transfer device 17 is located between the first region 101 and the second region 102, and the sample scanning device is located on one side of the sample loading device 11. After the sample container is removed from the sample loading device 11, it is scanned by the sample scanning device 15 before operation.

[0089] Optionally, such as Figures 1 to 3 As shown, the sample processing assembly also includes a liquid addition gripping device 13, which includes a liquid addition device and a sample clamp connected together. The sample clamp is used to transfer the sample container and / or open and close the lid of the sample container, and the liquid addition device is used to add liquid into the sample container.

[0090] In this embodiment, the liquid-adding gripping device 13 integrates the sample clamp and the liquid-adding device into one unit. The sample clamp can transfer the sample container within the first region 101 and can open and close the lid of the sample container. For example, the sample clamp can hold the sample container in the sample loading device 11 and place it at the sample scanning device for scanning, or it can place the sample container in the sample transfer device 17 for transfer. Simultaneously, the sample clamp can open or close the lid of the sample container to facilitate the extraction of the sample from the container, or to add other liquids to the sample container. In addition, the liquid-adding gripping device 13 also includes a liquid-adding device. When the sample is a sputum-like specimen, digestive fluid needs to be added to the sample to convert the viscous sputum into a liquid state for subsequent operations. Therefore, the liquid-adding extraction device of this embodiment integrates the liquid-adding device onto the sample clamp, achieving unified control and thus improving sample processing efficiency.

[0091] Optionally, the sample fixture further includes a guide rail assembly, a robotic arm 134, and a robotic arm gripper 135. The guide rail assembly includes an X-axis guide rail 136, a Y-axis guide rail 137, and a Z-axis guide rail 138. The robotic arm 134 is movably mounted on the Z-axis guide rail 138. The robotic arm gripper 135 is located at the lower end of the robotic arm 134 and is used to grip the sample container and / or open / close the lid of the sample tube. In this embodiment, the guide rail assembly includes an X-axis guide rail 136, a Y-axis guide rail 137, and a Z-axis guide rail 138, which enables the robotic arm gripper 135 to move in three directions, thereby increasing the range of motion of the sample fixture and improving the gripping flexibility. The robotic arm 134 is mounted on the Z-axis guide rail 138, and the robotic arm gripper 135 is located at the lower end of the robotic arm 134. The robotic arm 134 facilitates the robotic arm gripper 135 in grasping the sample container, and the robotic arm gripper 135 can grip and / or open / close the lid of the sample container.

[0092] Optionally, the X-axis guide rail 136 is movably mounted on the Y-axis guide rail 137, the Z-axis guide rail 138 is movably mounted on the X-axis guide rail 136, and the robotic arm 134 is movably mounted on the Z-axis guide rail 138. Specifically, the robotic arm 134 is slidably connected to the Z-axis guide rail 138, and the robotic arm 134 can move relative to the Z-axis guide rail 138 in a first direction. The Z-axis guide rail 138 drives the robotic arm 134 to move relative to the X-axis guide rail 136 in a second direction, and the Z-axis guide rail 138 and the X-axis guide rail 136 drive the robotic arm 134 to move relative to the Y-axis guide rail 137 in a third direction. Here, the first direction is the vertical direction, the second direction is the left-right direction, and the third direction is the front-back direction. It can be understood that the Z-axis guide rail 138 extends vertically, the X-axis guide rail 136 extends horizontally, and the Y-axis extends front-back.

[0093] Optionally, the robotic arm gripper 135 includes a first gripper and a second gripper. The first gripper and the second gripper can move towards each other or away from each other. When the first gripper and the second gripper move towards each other, the robotic arm gripper 135 can clamp the sample container. When the first gripper and the second gripper move away from each other, the robotic arm gripper 135 can release the sample container.

[0094] Optionally, the robotic arm gripper 135 is rotatably disposed at the lower end of the robotic arm 134, so that the robotic arm gripper 135 can rotate relative to the robotic arm 134. After the robotic arm gripper 135 clamps the lid of the sample container, the robotic arm gripper 135 can rotate counterclockwise or clockwise to open or close the lid of the sample container.

[0095] Optionally, the liquid dispensing device is located on one side of the robotic arm 134. The liquid dispensing device includes a connected liquid storage bottle 132, a liquid dispensing pump 133, and a liquid dispensing needle 131. The liquid dispensing needle 131 is connected to the robotic arm 134 and can move with the robotic arm 134 to dispense liquid to the sample container.

[0096] In this embodiment, the storage bottle 132 is used to hold the digestive fluid, and the dispensing needle 131 is used to dispense the fluid to facilitate the addition of the digestive fluid into the sample container. The dispensing pump 133 provides driving force for the flow of the digestive fluid in the storage bottle 132 to ensure that the digestive fluid can flow out from the dispensing needle 131. When the robotic arm gripper 135 opens the sample container, the robotic arm gripper 135 holds the lid of the sample container, and the robotic arm 134 drives the dispensing needle 131 to move to the left or right so that the dispensing needle 131 corresponds to the opening of the sample container. The dispensing pump 133 draws any amount of digestive fluid from the storage bottle 132 and adds it into the sample container. Then, the robotic arm 134 drives the dispensing needle 131 to move in the opposite direction, the robotic arm gripper 135 aligns with the sample container, and rotates the lid of the sample container onto the sample container.

[0097] Optionally, the liquid storage bottle 132 is connected to the robotic arm 134 and / or the Z-axis guide rail 138 to prevent the tubing of the liquid storage bottle 132 from affecting the movement of the robotic arm 134.

[0098] Optionally, the liquid pump 133 is connected to the robotic arm 134 and / or the Z-axis guide rail 138 to prevent the pipeline between the liquid storage bottle 132 and the liquid pump 133 from affecting the movement of the robotic arm 134.

[0099] Optionally, the liquid injection needle 131 is located on one side of the robotic arm gripper 135, and the lower end of the liquid injection needle 131 is at the same or similar height to the lower end of the robotic arm gripper 135. This facilitates the liquid injection needle 131 to move above the sample container after the robotic arm gripper 135 opens the cover of the sample container, so as to add digestive fluid into the sample container.

[0100] Optionally, the sample holder also includes a pressure sensor located on the robotic arm gripper 135. When the robotic arm gripper 135 grips the sample container, the pressure sensor can provide feedback on the pressure to determine whether the robotic arm gripper 135 has clamped the sample container tightly, thus avoiding failure to grip or excessive gripping.

[0101] Optionally, when the sample container is opened or closed, the robotic arm gripper 135 rotates a preset number of times. The preset number of times can be set according to rotation memory to ensure the stability of opening and closing the sample container and avoid problems such as the container not rotating when opening or excessive pressure when closing.

[0102] Optionally, such as Figure 1 As shown, the sample processing assembly 10 also includes a shaking device 14, which is located above the worktable 100. The shaking device 14 has a shaking groove. The sample holder can transfer the sample container from the sample loading device 11 into the shaking groove. The shaking device 14 is used to shake the sample container to improve the mixing uniformity of the solution in the sample container. In addition, the shaking groove can also fix the sample container, so that the sample holder can open and close the lid of the sample container, and it is also convenient for the liquid addition device to add liquid.

[0103] Optionally, the shaking device 14 is located below the robotic arm gripper 135 of the sample holder. The depth of the shaking groove is less than the height of the sample container, and the difference between the depth of the shaking groove and the height of the sample container is the same as or similar to the height of the sample container's lid. In this way, when the sample container is placed in the shaking groove, the robotic arm gripper 135 can clamp the lid of the sample container to facilitate opening or closing the lid. At the same time, after the sample container is opened, the liquid addition device can also move to the top of the sample container with the guide rail assembly or the robotic arm 134. Driven by the liquid addition pump 133, the liquid addition needle 131 adds the digestive liquid from the storage bottle 132 into the opened sample container.

[0104] Optionally, such as Figure 3 As shown, the sample holder also includes a fixing member 139, which is located on the robotic arm 134 and is situated on one side of the robotic arm gripper 135. When liquid is added to the sample container, and when it is necessary to shake the sample container, the robotic arm 134 moves the fixing member 139 to the top of the sample container, where the fixing member 139 can abut against the top of the sample container. In this way, when the sample container is shaken, the fixing member 139 can prevent the sample container from shifting or escaping from the shaking groove.

[0105] Optionally, the fixing member 139 is located behind the gripper 135 of the robotic arm. Optionally, the cross-sectional area of ​​the fixing member 139 is larger than the opening area of ​​the sample container to prevent sample from splashing out of the sample container. For example, the fixing member 139 can be elongated or circular, etc.

[0106] Optionally, the sample processing assembly also includes a heating device 142, with the liquid dispensing device located on one side of the shaking device 14 for heating the sample in the sample container.

[0107] In this embodiment, the heating device 142 can heat the solution inside the sample container to incubate the sample. The heating device 142 is located on one side of the shaking device 14, so that after the sample container is shaken by the shaking device 14, it can be transferred to the heating device 142 for incubation using a sample holder. In practical use, the sample container can be selectively placed at the heating device 142 and / or the shaking device 14 depending on the type of sample.

[0108] Optionally, the sample processing assembly also includes a sample collection device 16, which is located on the side of the sample transfer device 17 facing the first region 101, for collecting the sample container after sample extraction.

[0109] Optionally, the sample loading device 11, sample scanning device 15, and heating device 142 are arranged sequentially along the length of the first region 101. The liquid-adding gripping device 13 is located on the side of the sample loading device 11, sample scanning device 15, and heating device 142 away from the second region 102, and the sample clamp is located above the sample loading device 11, sample scanning device 15, shaking device 14, and heating device 142 to facilitate the transfer of sample containers between these devices. This fully utilizes the space of the first region 101 and rationally arranges the position of each device, which not only meets the requirements of biological detection experiments but also saves space, reduces the movement path of the sample clamp, and improves sample processing efficiency.

[0110] Optionally, the shaking device 14 and the heating device 142 are arranged side by side in the left-right direction. The sample loading device 11 is located in front of the shaking device 14 and the heating device 142, and the sample scanning device and the sample collection device are located between the sample loading device 11 and the shaking device 14 and the heating device 142. The sample scanning device is located in front of the sample collection device. The sample transfer device 17 is located to the right of the sample loading device 11 and the sample collection device 16, which reduces the movement path of the sample holder when the sample transfer device 17 is used in conjunction with other devices. The Y-axis guide rail 137 of the sample holder is located to the left of the sample loading device 11 and the oscillation device 14, and the length of the Y-axis guide rail 137 is the same as or similar to the length of the first region 101. The X-axis guide rail 136 is located behind the oscillation device 14 and the heating device 142, and the width of the X-axis guide rail 136 is the same as or similar to the width of the first region 101. This increases the range of motion of the robotic arm 134, ensuring that the robotic arm 134 can grip any position in the first region 101, thereby facilitating the transfer of sample containers without the need for multiple sample holders. For example, the sample container from the sample loading device 11 can be gripped to the sample scanning device for scanning, or the sample container can be gripped to the oscillation device 14 or the heating device 142, or the sample container can be gripped to the sample transfer device 17 for transfer, or the extracted sample container can be transferred to the sample collection device.

[0111] Optionally, such as Figure 1 As shown, the sample transfer device 17 includes a transfer platform, a second slide, and a drive device. The transfer platform is used to place the sample container and is slidably disposed on the second slide. The drive device can drive the transfer platform to move along the second slide, which extends from the first region 101 to the second region 102. Thus, after the sample holder places the processed sample on the transfer platform, the transfer platform can move along the second slide to the sample extraction station 601 in the second region 102, so that the inoculation device 50 can extract the solution from the sample container.

[0112] Optionally, such as Figure 1 As shown, the sample processing assembly also includes a receiving device 12, located in the first region near the second region. The receiving device includes a receiving cover and a driving mechanism, which drives the receiving cover to move horizontally. After the liquid application gripping device places the sample container into the sample transfer device 17, the sample clamp opens the sample container. The lid of the sample container is held by the liquid application device. After opening, the sample container is transferred to the second region with the sample transfer device. The receiving cover of the receiving device moves to below the sample clamp and is located below the lid of the sample container to catch any liquid dripping from the lid of the sample container, preventing liquid from dripping onto the worktable.

[0113] Optionally, such as Figure 1 and Figure 2 As shown, the sample collection assembly 30 includes a gripping device 35, a printing device 33, a coding device 34, a slide collection device, and a petri dish sample collection device 31. The gripping device 35 includes a sample collection gripper 214, which is movably disposed between the third region 103 and the second region 102 and the third region 103, for gripping or transferring the petri dish 40 or the slide. The printing device 33 is correspondingly disposed to the petri dish sample collection device 31 and is used to print labels and affix the labels to the petri dish 40. The coding device 34 is correspondingly disposed to the slide sample collection device and is used to code the slide.

[0114] In this embodiment, the gripping device 35 can grip and transfer the scribed culture dish 40 or the smeared glass slide, thereby realizing the storage of the culture dish 40 or the glass slide. The printing device 33 is used to label the scribed culture dish 40, and the inkjet printing device 34 is used to inkjet print the smeared glass slide, thereby realizing the recording and summarization of the culture dish 40 and the glass slide.

[0115] Optionally, such as Figure 6 As shown, the slide receiving device 32 includes a moving platform 322, a receiving device 321, and a second pusher 323. The moving platform 322 is movably mounted on the worktable 100 and is used to place the smeared slides. The receiving device 321 is vertically mounted on the worktable 100, and the moving platform 322 can move to one side of the receiving device 321. The dispensing device 221 is constructed with a plurality of second storage compartments 3211 arranged vertically. The second storage compartments 3211 are used to place the smeared slides. The second pusher 323 is located on one side of the receiving device 321 and is used to push the slides from the moving platform 322 into the second storage compartments 3211.

[0116] In this embodiment, after the slides are coated on the tray 231, the gripping device 35 transfers the coated slides to the moving platform 322. The moving platform 322 is movable relative to the worktable 100 and can move to one side of the sample receiving device 321 and engage with it. The second push rod 323 pushes the slides on the moving platform 322 into the second storage compartment 3211. The sample receiving device 321 can also be raised and lowered relative to the worktable 100. When the storage compartment corresponding to the second push rod 323 is loaded with a slide, the sample receiving device 321 can rise or fall so that the empty second storage compartment 3211 corresponds to the second push rod 323, so as to place another slide.

[0117] Optionally, such as Figure 8As shown, the petri dish sample receiving device 31 includes a sample receiving platform 311, a sample receiving chamber 312, a lifting mechanism 313, a slide rail 314, and a flipping mechanism 315. A sample receiving platform 311 is movably mounted on the workbench 100. A sample receiving chamber 312 is mounted on the sample receiving platform 311 and extends vertically. The sample receiving chamber 312 defines multiple storage spaces for placing labeled culture dishes 40. A lifting mechanism 313 is located at the bottom of the storage space and is used to raise and lower the culture dishes 40 in the storage space. One end of a slide rail 314 is connected to the sample receiving chamber 312, and the other end of the slide rail 314 corresponds to the printing device 33. A gripping device 35 can grip the culture dishes 40 on the slide rail 314 so that the culture dishes 40 move along the slide rail 314 into the sample receiving chamber 312. A flipping mechanism 315 is located on the slide rail 314 and is used to flip the culture dishes 40 on the slide rail 314 so that the culture dishes 40 are inverted and stored in the storage space.

[0118] In this embodiment, after the gripping device 35 marks the culture dish 40, it is transferred to the printing device 33 for labeling. The labeled culture dish 40 then moves along the slide rail 314 to the culture dish receiving device 31 for collection. Specifically, the labeled culture dish 40 moves towards the receiving platform 311. The slide rail 314 is equipped with a flipping mechanism 315, which flips the culture dish 40, allowing it to be stored upside down in the receiving chamber 312. This facilitates the growth of the bacteria within the culture dish 40 and maintains the compactness of the culture dish 40.

[0119] Optionally, one end of the slide rail 314 is connected to the bottom of the storage space. After being flipped, the culture dish 40 moves with the slide rail 314 to the bottom of the corresponding storage space. The lifting mechanism 313 drives the culture dish 40 to rise to a preset position. The preset position refers to the position where the culture dish 40 contacts the lower wall of the culture dish 40 already stored in the storage space. The petri dish collection device 31 also includes a stop mechanism 316, which is movably located at the bottom of the storage space. The stop mechanism 316 can move between the fifth position and the sixth position. When the stop mechanism 316 is in the fifth position, it does not obstruct the storage space, and the lifting mechanism 313 can lift the petri dish 40. After the lifting mechanism 313 lifts the petri dish 40 to the preset position, the stop mechanism 316 moves to the sixth position, where it obstructs the bottom opening of the storage space and abuts against the lower wall of the bottommost petri dish 40 to prevent it from falling and to reserve enough space for the next petri dish 40. At the same time, the stop mechanism 316 does not block the lifting mechanism 313. After the stop mechanism 316 abuts against the bottom of the petri dish 40, the lifting mechanism 313 descends.

[0120] Optionally, the stop structure includes a rotating shaft and a stop plate. The stop plate is rotatably connected to the operating platform 211 via the rotating shaft. When the stop mechanism 316 is in the fifth position, the stop plate extends upward or downward to facilitate the raising of the culture dish 40. When the stop mechanism 316 is in the sixth position, the stop plate extends toward the bottom opening of the storage space to reduce the bottom opening area of ​​the storage space and facilitate contact with the culture dish 40.

[0121] Optionally, such as Figure 9 As shown, the printing device 33 includes a printer 331, a labeling platform 333, and a labeling mechanism 332. The labeling platform 333 is located on one side of the printer 331 and is used to hold the petri dish 40 to be labeled. The labeling mechanism 332 is located on one side of the printer 331 and is used to label the petri dish 40 on the labeling platform 333.

[0122] When the culture dish 40 is labeled, the gripping device 35 holds the culture dish cover 41, and the culture dish box 42 moves downward. The culture dish box 42 moves downward a preset distance, increasing the exposure height of the side wall of the culture dish box 42, so that the labeling mechanism 332 can label the side wall of the culture dish box 42.

[0123] In this embodiment, the inoculated culture dish 40 is transferred to the printing platform by the gripping device 35. When the culture dish 40 moves above the printing platform, the gripping device 35 clamps the culture dish cover 41, so the culture dish box 42 moves downward a preset distance under the action of gravity. At this time, the exposed area of ​​the side wall of the culture dish box 42 increases, which makes it easier for the labeling mechanism 332 to affix the label to the side wall of the culture dish cover 41. This not only realizes the automatic labeling of the culture dish 40, but also facilitates the subsequent observation of the culture dish 40.

[0124] Optionally, when the culture dish box 42 moves downward a predetermined distance, the culture dish lid 41 connects to the culture dish box 42, so that the culture dish lid 41 is in a closed state. That is to say, when the culture dish 40 is labeled, the culture dish lid 41 and the culture dish box 42 are not completely separated, which can prevent the culture dish 40 from being contaminated during the labeling process.

[0125] Optionally, the gripping device 35 includes a moving device, a gripping robotic arm 134, a first gripping claw 214, and a second gripping claw 214. The gripping robotic arm 134 is connected to the moving device and can move with the moving device between the second region 102 and the third region 103, and between the third region 103. The first gripping claw 214 and the second gripping claw 214 are located at the lower end of the gripping robotic arm 134. The first gripping claw 214 is located outside the second gripping claw 214, and the length of the first gripping claw 214 is greater than the length of the second gripping claw 214. When the gripping device 35 grips the culture dish 40, the second gripping claw 214 adheres to the top of the culture dish cover 41, and the first gripping claw 214 clamps the circumferential outer wall of the culture dish box 42 to move the culture dish 40. When the gripping device 35 moves the culture dish 40 above the labeling platform 333, the first gripping claw 214 releases, and the second gripping claw 214 adsorbs the culture dish cover 41. In this way, the culture dish box 42 can move downward a preset distance under the action of gravity, which facilitates labeling.

[0126] Optionally, such as Figure 1 and Figure 6 As shown, the slide receiving device 32 includes a moving platform 322, a receiving device 321, and a second pusher 323. The moving platform 322 is movably mounted on the worktable 100 and is used to place the smeared slides. The receiving device 321 is vertically mounted on the worktable 100. The moving platform 322 can move to one side of the receiving device 321. The receiving device 321 is constructed with a plurality of second storage compartments 3211 arranged vertically. The second storage compartments 3211 are used to place the smeared slides. The second pusher 323 is located on one side of the receiving device 321 and is used to push the slides from the moving platform 322 into the second storage compartments 3211.

[0127] In this embodiment, the coated slide is transferred from the tray 231 to the moving platform 322 via the gripping device 35. The moving platform 322 moves the coated slide to one side of the receiving device 321. When the moving platform 322 is in contact with or close to the receiving platform 311, the second push rod 323 pushes the slide on the moving platform 322 into the second storage compartment 3211. After the second storage compartment 3211 corresponding to the second push rod 323 is filled with a slide, the receiving device 321 adjusts the position of the second storage compartment 3211 by raising and lowering it so that the empty second storage compartment 3211 corresponds to the second push rod 323 and the moving platform 322, so as to facilitate the storage of the coated slide.

[0128] Optionally, the moving platform 322 is equipped with a heating element that can increase the temperature of the moving platform 322. Thus, after the smeared slide is placed on the moving platform 322, the increased temperature of the moving platform 322 by the heating element can increase the drying speed of the sample on the slide.

[0129] Optionally, the mobile platform 322 is slidably connected to the worktable 100. The worktable is provided with a mobile slide rail 314. The mobile platform 322 is slidably connected to the mobile slide rail 314. The mobile slide rail 314 extends in the front-back direction. One end of the mobile slide rail 314 corresponds to the sample receiving device 321 so that the smeared glass slide can move to be close to the sample receiving device 321.

[0130] Optionally, the sliding rail 314 is located on the side of the scribing device 23 facing the third region 103, and the sliding rail 314 is located between the labeling device and the scribing device 23, with the sample receiving device 321 located in front of the sliding rail 314. This shortens the distance from the gripping device 35 to the moving platform 322 after the slide is gripped. Since the slide does not need to be labeled, the sample receiving process is relatively simple. Setting the sliding rail 314 on the side of the third region 103 closer to the second region 102 makes the system structure more compact, and the sample receiving device 321 being located in front also facilitates user replacement of the sample receiving device 321.

[0131] Optionally, such as Figures 10 to 14 As shown, the inoculation device 50 includes a worktable 100, a rotating frame 51, an inoculation ring 52, and operating stations. The rotating frame 51 is disposed on and rotatably connected to the worktable 100. The inoculation ring 52 is disposed on the rotating frame 51. The operating stations are disposed on the worktable 100 and correspond to the rotating frame 51. There are multiple operating stations, which are spaced apart along the circumference of the rotating frame 51 for operation in conjunction with the inoculation ring 52. The rotating frame 51 drives the inoculation ring 52 to rotate around the axial direction of the rotating frame 51, so that the inoculation ring 52 can be operated in conjunction with different operating stations.

[0132] In this embodiment, the workbench 100 is used to mount the rotating frame 51 and the inoculation station 602. The rotating frame 51 is rotatable relative to the workbench 100. An inoculation ring 52 is mounted on the rotating frame 51, which drives the inoculation ring 52 to rotate around its axial direction. This allows the inoculation ring 52 to cooperate with multiple inoculation stations 602 corresponding to the rotating frame 51, enabling the inoculation ring 52 to perform different operations. This improves the automation and efficiency of the inoculation process. Furthermore, multiple different operating stations can be configured as needed; for example, a sterilization station 604 can be set to sterilize the inoculation ring 52 after inoculation, or a cleaning station 603 can be set to clean the sterilized inoculation ring 52 to prevent ash accumulation. This improves both the effectiveness and efficiency of inoculation.

[0133] Optionally, such as Figure 10As shown, the multiple operating stations include at least two of the following: sample extraction station 601 (corresponding to the state when the aforementioned sample transfer device moves to the extraction position), inoculation station 602 (corresponding to the aforementioned streak smear device 23), sterilization station 604, and cleaning station 603.

[0134] In this embodiment, two or more operating stations can be provided. The sample extraction station 601 is used for extracting samples using the inoculation loop 52. The inoculation station 602 is used to perform inoculation in conjunction with the inoculation loop 52. The sterilization station 604 is used to sterilize the inoculation loop 52. The cleaning station 603 is used to clean the inoculation loop 52 to prevent the generation of ash.

[0135] Optionally, when multiple operating stations include a sample extraction station 601, an inoculation station 602, a sterilization station 604, and a cleaning station 603, these stations are arranged sequentially and at intervals along the circumference of the rotating frame 51. This can be understood as follows: starting from the sample extraction station 601, the inoculation loop 52 sequentially engages with the sample extraction station 601 to extract the sample, then rotates to the inoculation station 602 for inoculation. After inoculation, the inoculation loop 52 rotates to the cleaning station 603 for cleaning, and then rotates to the sterilization station 604 for sterilization. The sterilized inoculation loop 52 then rotates back to the sample extraction station 601 for sample extraction. This improves both the efficiency of inoculation and the cleaning effect on the inoculation loop 52, thus enhancing the overall inoculation effect.

[0136] Optionally, there may be multiple inoculation rings 52, which are arranged sequentially at intervals along the circumference of the rotating frame 51. In this embodiment of the present disclosure, the number of inoculation rings 52 may also be multiple, so that when the rotating frame 51 rotates, the multiple inoculation rings 52 can cooperate with different operating stations respectively, further improving work efficiency.

[0137] Optionally, the number of inoculation rings 52 is the same as the number of operating stations, and each inoculation ring 52 can cooperate with one operating station when it rotates. This eliminates the need for too many inoculation rings 52, saving costs, and also allows each inoculation ring 52 to cooperate with an operating station to perform multiple operations simultaneously when the inoculation device 50 is working, thus improving work efficiency.

[0138] Optionally, when multiple operating stations include sample extraction station 601, inoculation station 602, sterilization station 604, and cleaning station 603, the number of inoculation loops 52 is four. In this way, when the inoculation device 50 is working, each operating station has an inoculation loop 52, and the inoculation work does not need to wait, thus improving work efficiency.

[0139] Optionally, the inoculation ring 52 is rotatably connected to the rotating frame 51. The inoculation ring 52 can rotate relative to the rotating frame 51 in a first position and a second position. When the inoculation ring 52 is in the first position, there is a first angle between the inoculation ring 52 and the vertical direction, and the head of the inoculation ring 52 can correspond to the first operating station. When the inoculation ring is in the second position, there is a second angle between the inoculation ring 52 and the vertical direction, and the head of the inoculation ring 52 corresponds to the second operating station. The second angle is greater than the first angle. The multiple inoculation stations include the first operating station and the second operating station.

[0140] In this embodiment, the height of the inoculation station 602 is less than the height of the rotating frame 51, which facilitates the alignment of the head of the inoculation loop 52 with different operating stations. The inoculation loop can rotate relative to the rotating frame, improving its operational flexibility. The angle of the inoculation loop can be adjusted according to the position and angle of different operating stations to allow it to align with various positions. For example, a station with less stringent angle requirements for the inoculation loop can be defined as the first operating station. The inoculation loop can correspond to the first operating station, such as being able to be inserted into it, without needing to move relative to the first operating station. Therefore, the first included angle of rotation of the inoculation loop corresponding to the first operating station needs to be small. The second operating station can be the inoculation station where the operation is required. In this case, the included angle between the inoculation loop and the vertical direction is larger, facilitating inoculation or smearing of culture dishes or glass slides.

[0141] Optionally, the first operating station includes at least one of a sample extraction station, a sterilization station, and a cleaning station, and the second operating station includes an inoculation station, wherein when the inoculation loop is in the first position, the head of the inoculation loop can be inserted into the first operating station. The first inoculation station is one where the angle requirement for the inoculation loop is not high; the inoculation loop only needs to be able to be inserted into the first operating station. Therefore, the first included angle of rotation of the inoculation loop corresponding to the first operating station can be small. The second operating station is the inoculation station where the operation is required. At this time, the included angle between the inoculation loop and the vertical direction is larger, which facilitates inoculation or smearing of culture dishes or glass slides.

[0142] Optionally, when the inoculation loop 52 rotates relative to the rotating frame 51 to the first position, the inoculation loop 52 can correspond to the sample extraction station 601, sterilization station 604, or cleaning station 603. These operating stations have relatively small angle requirements for the inoculation loop 52; the head of the inoculation loop 52 can be inserted into the corresponding operating station to perform the operation. When the inoculation loop rotates to the second position, the head of the inoculation loop 52 corresponds to the inoculation station 602. The inoculation station 602 requires the inoculation loop 52 to perform streaking or smearing operations, which requires a larger range of motion and angle of movement for the inoculation loop 52. Therefore, when the inoculation loop 52 is in the second position, the angle between the inoculation loop 52 and the vertical direction is larger, resulting in a greater degree of tilt for the inoculation loop 52, thus facilitating streaking or smearing operations.

[0143] It should be noted that the first and second operating stations can also be other stations. For example, the second operating station can include one or more of the cleaning, sterilization, and extraction stations. In actual use, the angle of the inoculation ring can be adjusted according to the setting position and angle of different inoculation stations, so that the inoculation ring can cooperate with different operating stations and improve the flexibility of the inoculation device.

[0144] Optionally, the inoculation loop can rotate vertically relative to the rotating frame, allowing the angle between the inoculation loop and the vertical direction to be adjusted. Optionally, the inoculation loop is rotatably connected to the outer edge of the rotating frame, or the inoculation loop is rotatably connected to the rotating frame near the outer edge, so that the inoculation loop has sufficient space to rotate and avoids interference between the inoculation loop and the connecting components.

[0145] Optionally, the first included angle ranges from 0 degrees to 10 degrees. When the inoculation loop 52 corresponds to the sample extraction station 601, sterilization station 604, or cleaning station 603, the inoculation loop 52 can be set vertically or at a small angle to the vertical direction, as long as it can be inserted into the corresponding operating station. The first included angle should not be too large. If the first included angle is too large, it increases the horizontal distance between the operating station and the rotating frame 51, increases the size of the inoculation device 50, and makes installation inconvenient.

[0146] Optionally, the range of the second included angle is 30 degrees to 80 degrees, which increases the horizontal distance between the inoculation station 602 and the rotating frame 51, making it easier to set up the inoculation station 602 and also easier to coordinate the head of the inoculation ring 52 with the inoculation station 602.

[0147] Optionally, the height of the operating station is less than the height of the rotating frame 51. The head of the inoculation loop 52 is located below the inoculation loop 52, and the tail of the inoculation loop 52 is located above the inoculation loop 52. The inoculation loop 52 can rotate vertically relative to the rotating frame 51. When the inoculation loop 52 moves from the first position to the second position, the tail of the inoculation loop 52 moves downward and towards the rotating frame 51, while the head of the inoculation loop 52 moves upward and away from the axis of the rotating frame 51, so that the inoculation loop 52 is tilted. This ensures that the inoculation station 602 has a horizontal distance from the rotating frame 51, which facilitates the coordination of the inoculation station 602 with other sample loading or receiving devices 321, facilitates the movement of the inoculation station 602 itself, and also facilitates the marking or smearing of the head of the inoculation loop 52.

[0148] Optionally, the inoculation station 602 is located outside the projection of the rotating frame 51 onto the workbench 100 in a top-to-bottom direction, and the minimum horizontal distance between the inoculation station 602 and the outer edge of the rotating frame 51 is greater than the minimum horizontal distance between the sample extraction station 601, the sterilization station 604, or the cleaning station 603 and the outer edge of the rotating frame 51. It can be understood that the horizontal distance between the inoculation station 602 and the rotating frame 51 is the greatest; therefore, when the inoculation loop is in the second position, the second included angle is greater than the first included angle. With the inoculation station 602 being the farthest horizontally from the rotating frame 51, the workbench 100 has sufficient space to set up the operating station, and the inoculation loop 52 is tilted, increasing the range of motion of the inoculation loop 52 and improving the effect of scribing and smearing.

[0149] Optionally, such as Figure 12 As shown, the inoculation device 50 also includes a connecting component and a boss 56. The connecting component is connected between the rotating frame 51 and the worktable 100. The rotating frame 51 can rotate relative to the connecting component. The boss 56 is located on the connecting component, on one side of the rotating frame 51, and corresponds to the inoculation station 602. The boss 56 protrudes from the outer wall surface of the rotating frame 51 in the circumferential direction. When the inoculation ring 52 rotates around the axial direction of the rotating frame 51 and moves toward the inoculation station 602, the boss 56 contacts the inoculation ring 52 and lifts the head of the inoculation ring 52, so that the inoculation ring 52 moves from the first position to the second position.

[0150] In this embodiment of the disclosure, the connecting component is used to connect the rotating frame 51 to the worktable 100. The rotating frame 51 can rotate relative to the connecting component, thereby realizing the rotational connection between the rotating frame 51 and the worktable 100. The boss 56 is located on the connecting assembly, so that the boss 56 will not rotate when the rotating frame 51 rotates. The boss 56 protrudes from the outer circumferential wall of the rotating frame 51 and corresponds to the inoculation station 602. When the inoculation ring 52 moves from other operating stations toward the inoculation station 602, the inoculation ring 52 will contact the boss 56. Since the inoculation ring 52 is rotatably connected to the rotating frame 51, the inoculation ring 52 can rotate under the action of the boss 56, thereby allowing the inoculation ring 52 to rotate from the first position to the second position. When the inoculation ring 52 has finished inoculating and moves away from the inoculation station 602, the inoculation ring 52 will no longer contact the boss 56 and will return to the first position under its own gravity. In this way, the rotation of the inoculation ring 52 relative to the rotating frame 51 can be achieved without setting a drive structure, saving energy and increasing efficiency.

[0151] Optionally, the inoculation ring 52 includes an inoculation ring body and a roller 527. The roller 527 is located on one side of the inoculation ring body. When the inoculation ring 52 contacts the boss 56, the roller 527 contacts the boss 56 and rolls along the boss 56. When the inoculation ring 52 moves to the second position, the roller 527 separates from the boss 56.

[0152] In this embodiment, the roller 527 is disposed on one side of the inoculation ring 52. When the inoculation ring 52 contacts the boss 56, the inoculation ring 52 contacts the boss 56 through the roller 527, and the roller 527 can roll along the boss 56. This increases the contact area between the inoculation ring 52 and the boss 56, buffering the impact force of the boss 56 on the inoculation ring 52. In addition, the roller 527 has a certain height, and when the roller 527 contacts the boss 56, it can quickly increase the tilt angle of the inoculation ring 52, thereby increasing the speed at which the inoculation ring 52 moves from the first position to the second position and improving the inoculation efficiency.

[0153] Optionally, the rotating frame 51 includes a rotating frame body, a fixed frame 512, and a rotating shaft. The rotating frame body defines a plurality of mounting positions 511 spaced circumferentially along the rotating frame body. The fixed frame 512 is located at the outer end of the mounting position 511 and has a rotating groove 513. The two opposite sidewalls of the rotating groove 513 extend vertically. The inoculation ring 52 is rotatably located within the rotating groove 513. The two opposite sidewalls of the rotating groove 513 have a first rotating hole, and the inoculation ring has a second rotating hole corresponding to the first rotating hole. The rotating shaft passes through the first rotating hole and the second rotating hole so that the inoculation ring can rotate within the rotating groove 513.

[0154] In this embodiment, the mounting position 511 is used to mount the inoculation ring 52. The fixing frame 512 is located at the outer end of the mounting position 511, and the fixing frame 512 is constructed with a rotating groove 513. The two opposite sidewalls of the rotating groove 513 extend vertically, so that the front, back, and top ends of the rotating groove 513 are all open. The inoculation ring 52 is rotatably mounted in the rotating groove 513 via a rotating shaft, which allows the inoculation ring 52 to rotate vertically. Moreover, the fixing frame 512 is located at the outer end of the mounting position 511, so that the rotation of the inoculation ring 52 is not hindered by the rotating frame 51, thus improving the degree of freedom of rotation.

[0155] Optionally, the rotating frame body includes a center plate and mounting plates. The mounting plates are connected to the outside of the center plate and extend away from the center plate. Multiple mounting plates are arranged at intervals along the circumference of the center plate, and each mounting plate has mounting positions 511. This spacing between adjacent mounting plates away from the center plate reduces the weight of the rotating frame 51, lowers costs, and reduces interference from the rotating frame 51 on the rotation of the inoculation ring 52, improving rotational smoothness.

[0156] Optionally, the inoculation device 50 further includes a first magnetic element 53 and a first magnetic mating element 531. The first magnetic element 53 is disposed at the tail of the inoculation ring 52 and located on one side of the rotating shaft. When the inoculation ring 52 is in the second position, the first magnetic element 53 extends in the vertical direction. The first magnetic mating element 531 is disposed on the rotating frame 51 and corresponds to the inoculation station 602. When the inoculation ring 52 moves to the inoculation station 602 and rotates to the second position, the first magnetic element 53 corresponds to the first magnetic mating element 531, and a repulsive magnetic force is formed between the first magnetic element 53 and the first magnetic mating element 531 to apply a downward force to the head of the inoculation ring 52.

[0157] In this embodiment, a first magnetic element 53 is provided at the tail of the inoculation ring 52. The first magnetic element 53 and the first magnetic mating element 531 generate a repulsive magnetic force, which can further apply force to the inoculation ring 52 so that the inoculation ring 52 can contact the inoculation device 50 of the inoculation station 602, improving the accuracy of the marking. In this way, the boss 56 provides the main force for the movement of the inoculation ring 52, and the first magnetic element 53 can fine-tune the position of the inoculation ring 52 to ensure the accuracy of the position of the inoculation ring 52. In addition, the first magnetic element 53 itself has a certain weight. When the inoculation ring 52 moves from the first position to the second position, the first magnetic element 53 can act as a moving counterweight, improving the movement efficiency and accuracy of the inoculation ring 52.

[0158] Optionally, both the first magnetic component 53 and the first magnetic mating component 531 are magnets.

[0159] Optionally, the inoculation device 50 further includes a first limiting post 532 and a second limiting post 533. The first limiting post 532 is located at the tail of the inoculation ring 52 and on one side of the rotating shaft. The second limiting post 533 is located on the rotating frame 51 and corresponds to the inoculation station 602. When the inoculation ring 52 moves to the inoculation station 602 and rotates to the second position, the first limiting post 532 and the second limiting post 533 correspond to each other and are spaced apart. When the first limiting post 532 and the second limiting post 533 come into contact, the head of the inoculation ring 52 is restricted from moving upward.

[0160] In this embodiment, the tail of the inoculation loop 52 is further provided with a first limiting post 532, and the rotating frame 51 is provided with a second limiting post 533. When the inoculation loop 52 rotates to the second position, the first limiting post 532 and the second limiting post 533 are correspondingly and spaced apart. When the first limiting post 532 and the second limiting post 533 contact each other, the head of the inoculation loop 52 is restricted from rotating upward. In this way, the first limiting post 532 and the second limiting post 533 limit the rotation range of the inoculation loop 52, which can prevent the inoculation loop 52 from rotating too far and causing damage to the inoculation loop 52. In addition, the first limiting post 532 can also act as a counterweight, increasing the weight of the tail of the inoculation loop 52 and increasing the speed at which the inoculation loop 52 moves from the first position to the second position.

[0161] Optionally, the first limiting post 532 is located on the side of the first magnetic element 53 away from the rotating shaft.

[0162] Optionally, the length of the first limiting post 532 is less than the length of the first magnetic element 53.

[0163] Optionally, the inoculation device 50 further includes a detection device 534, which is located on the rotating frame 51 and corresponds to the inoculation station 602. The detection device 534 is used to detect the position information of the inoculation ring 52 that has moved to the inoculation station 602. The controller is electrically connected to the detection device 534 and is used to receive the position information of the inoculation ring 52 at the inoculation station 602.

[0164] In this embodiment of the present disclosure, the detection device 534 can detect whether the inoculation ring 52 has rotated to the second position and detect the rotation accuracy of the inoculation ring 52. The detection device 534 sends the detection information to the controller, and the controller can issue a prompt or control the movement of related equipment based on the detection information.

[0165] Optionally, the vaccination device 50 also includes a prompting device electrically connected to a controller, which is configured to activate the prompting device to alert the user when the vaccination ring 52 has not moved to the second position.

[0166] For example, the notification device could be a light, an alarm, etc.

[0167] Optionally, the detection device 534 corresponds to the second limiting post 533, and the detection device 534 is used to detect the position of the first limiting post 532. In this way, when the first limiting post 532 deviates from the preset position, the detection device 534 can detect that the inoculation ring 52 has not moved to the second position and send a message to the controller.

[0168] For example, the detection device 534 is a photoelectric detection device 534.

[0169] Optionally, the inoculation device 50 further includes an upper housing 55, which covers the rotating frame 51 and is rotatably disposed within the upper housing 55. The upper housing 55 defines a cylindrical space with an opening at the bottom, and a notch 551 is provided on the side wall of the upper housing 55. The notch 551 communicates with the opening and corresponds to the boss 56, so that when the inoculation ring 52 moves toward the inoculation station 602, the notch 551 can prevent the inoculation ring 52 from rotating from the first position to the second position. When the inoculation ring 52 abuts against the upper side wall of the notch 551, the head of the inoculation ring 52 is restricted from moving upward.

[0170] In this embodiment, the rotating frame 51 is located inside the upper housing 55. The upper housing 55 protects the rotating frame 51 and the inoculation ring 52, reducing dust accumulation. Furthermore, the upper housing 55 provides a certain degree of restraint for the inoculation ring 52. When the inoculation ring 52 moves to an operating position other than the inoculation station 602, the side wall of the upper housing 55 restrains the inoculation ring 52, preventing it from rotating too much and coming into contact with other devices, thus avoiding damage. When the inoculation ring 52 moves from the previous operating position towards the inoculation station 602, a notch 551 is provided on the side wall of the upper housing 55. This notch 551 allows the inoculation ring 52 to pass through, providing sufficient space for its rotation, enabling it to rotate from the first position to the second position. When the inoculation ring 52 abuts against the upper side wall of the notch 551, the head of the inoculation ring 52 is restricted from moving upward. This allows the upper shell 55 to act as a limit, preventing the inoculation ring 52 from rotating too far and thus ensuring the accuracy of the inoculation work.

[0171] Optionally, the inoculation station 602 includes a tray 231, which is located on one side of the rotating frame 51. When the inoculation ring 52 rotates to correspond to the inoculation station 602 and rotates to the second position, the device to be inoculated 50 carried by the tray 231 abuts against the head of the inoculation ring 52 and applies an upward force to the inoculation ring 52 so that the inoculation ring 52 separates from the boss 56.

[0172] In this embodiment, after the inoculation ring 52 has rotated to its position in both the horizontal and vertical directions, the head of the inoculation ring 52 contacts the inoculation device 50 carried by the tray 231, so that the inoculation ring 52 can scribble or smear the inoculation device 50. At this time, the inoculation device 50 applies an upward force to the head of the inoculation ring 52, which raises the height of the inoculation ring 52, thereby separating the inoculation ring 52 from the boss 56. In this way, except for the two contact points with the inoculation device 50 and the rotating shaft, the other parts of the inoculation ring 52 are suspended in the air, which reduces the resistance to the rotation of the inoculation ring 52 and improves the ease of rotation of the inoculation ring.

[0173] Optionally, the inoculation device 50 further includes a support member 54, a second magnetic member 541, and a second magnetic mating member. One end of the support member 54 is connected to the rotating frame 51, and the other end of the support member 54 extends above and in front of the rotating groove 513. The second magnetic member 541 is disposed on the side wall of the support member 54 facing the rotating frame 51. The second magnetic mating member is disposed on the rotating frame 51. When the second magnetic member 541 and the second magnetic mating member are attracted to each other, the inoculation ring is restricted from rotating relative to the rotating frame to fix the inoculation ring in the first position.

[0174] In this embodiment, one end of the support member 54 is fixed to the rotating frame 51, allowing the support member 54 to rotate with the rotating frame 51. When the inoculation ring 52 moves from the second position towards the first position, the second magnetic member 541 and the second magnetic mating member attract each other, thus fixing the inoculation ring 52 in the first position and preventing it from rotating. Furthermore, the other end of the support member 54 extends above and in front of the rotating groove 513, also limiting the movement of the inoculation ring 52 and preventing it from rotating excessively. Specifically, the second magnetic mating member is located on the side wall of the inoculation ring away from the rotating frame.

[0175] Optionally, such as Figure 11 As shown, the inoculation device 50 also includes an image recognition component and a display device. The image recognition component includes a light source 57, a prism 571, and a lens 572. The image recognition component corresponds to the sample extraction station 601. When the inoculation loop 52 corresponds to the sample extraction station 601, the head of the inoculation loop 52 is located between the light source 57 and the prism 571. The prism 571 is used to refract the light emitted by the light source 57 so that the lens 572 can acquire image information of the head of the inoculation loop 52. The display device is electrically connected to the lens 572 and is used to display image information of the head of the inoculation loop 52. The light source 57 is equipped with a reference device, which is used to compare the image information of the head of the inoculation loop 52 to determine whether the inoculation loop 52 has been successfully extracted.

[0176] In this embodiment, the head of the inoculation loop 52 corresponds to the light source 57, and the light source 57 emits light that illuminates the head of the inoculation loop 52. Here, when the inoculation loop 52 rotates to the inoculation station 602, the inoculation loop 52 should have extracted a sample from the sample extraction station 601; therefore, the head of the inoculation loop 52 should contain a sample. The head of the inoculation loop 52 is located between the light source 57 and the prism 571. The prism 571 can change the direction of the light emitted by the light source 57, allowing the lens 572, even though the light source 57 and the inoculation loop 52 are not on the same straight line, to capture an image of the inoculation loop 52. This improves the flexibility of the lens 572's mounting position 511 and reduces the size of the inoculation device 50. It can be understood that the prism can also be omitted, with the head of the inoculation loop 52 located between the light source 57 and the lens 572, and all three on the same straight line; in this case, an image of the head of the inoculation loop 52 can still be captured.

[0177] The light source 57 is equipped with a reference device. This allows the display device to simultaneously view images of both the head of the inoculation loop 52 and the reference device after the lens 572 captures a photograph of the loop's head. By comparing the photograph with the reference device image, it can be determined whether the extraction was successful. Furthermore, the position and angle of the inoculation loop 52 can also be identified and determined using the image information, improving the accuracy of the inoculation.

[0178] Optionally, the reference device is a grid line with multiple grids. When the inoculation loop 52 is successfully extracted, a liquid film will appear at the head of the inoculation loop 52. Under the refraction of the liquid film, the grid line will show a curve or twist. At this time, it can be determined that the inoculation loop 52 has been successfully extracted, and the next step of inoculation can be carried out. If no liquid film appears, the grid line will not show a curve or twist, and it is determined that the extraction has not been successful. The inoculation loop 52 can be controlled to return to the sample extraction station 601 for extraction. In addition, the position of the head of the inoculation loop 52 in the grid line can be used to determine whether the inoculation loop 52 has moved into place.

[0179] Optionally, the size of the liquid film is related to the size of the inoculation loop 52. Different reference sizes can be set for inoculation loops 52 of different sizes to achieve quantitative extraction and provide standardized sample liquid for subsequent microbial testing.

[0180] Optionally, the connecting assembly includes a lifting rod 581, which is movably mounted on the worktable 100. One end of the lifting rod 581 is connected to the rotating frame 51, which can drive the rotating frame 51 to rise and fall relative to the worktable 100. The inoculation device 50 also includes a first driving device, which is drivenly connected to the lifting rod 581 and is used to drive the lifting rod 581 to rise and fall.

[0181] In this embodiment, the lifting rod 581 can drive the rotating frame 51 to rise and fall, thereby enabling the inoculation ring 52 of the rotating frame 51 to move in the vertical direction. After the inoculation ring 52 rotates to the second position, the lifting rod 581 drives the inoculation ring 52 to fall, so that the inoculation ring 52 can contact the inoculation device 50. After the inoculation ring 52 has completed inoculation, the lifting rod 581 drives the inoculation ring 52 upward, and then the inoculation ring 52 rotates to the first position. This ensures that the inoculation ring 52 will not interfere with other equipment when rotating with the rotating frame 51.

[0182] Optionally, the first driving device includes a guide rail, a movable member 582, and a first motor 583. The guide rail extends vertically. The movable member 582 is connected to the other end of the lifting rod 581 and can slide along the guide rail. The first motor 583 is connected to the movable member 582 to drive the movable member 582 to slide along the guide rail, thereby driving the lifting rod 581 to rise and fall.

[0183] In this embodiment, the movable component 582 is connected to the lifting rod 581, and the first motor 583 drives the movable component 582 to move along the guide rail, thereby enabling the lifting rod 581 to rise and fall.

[0184] Optionally, the lifting rod 581 extends through the worktable 100, with one end of the lifting rod 581 located above the worktable 100 and the other end located below the worktable 100. The guide rail, movable component 582, and first motor 583 are all located below the worktable 100. This provides sufficient space to install a second drive device to increase the lifting stroke of the lifting rod 581 and ensure sufficient vertical movement space for the inoculation ring 52.

[0185] Optionally, the connecting assembly includes a hollow platform 584, which is connected between one end of the lifting rod 581 and the rotating frame 51, and the hollow platform 584 is rotatably connected to the rotating frame 51; the inoculation device 50 also includes a second driving device, which is disposed on the hollow platform 584 and is droop-connected to the rotating frame 51 to drive the rotating frame 51 to rotate relative to the hollow platform 584.

[0186] In this embodiment, a hollow platform 584 is connected between a lifting rod 581 and a rotating frame 51, the rotating frame 51 being rotatable relative to the hollow platform 584. A second driving device is fixed to the hollow platform 584 and then drivenly connected to the rotating frame 51, thereby driving the rotating frame 51 to rotate.

[0187] Optionally, the hollow platform 584 has an internal mounting cavity. The second drive device includes a second motor 585 and a transmission device. The second motor 585 is fixedly mounted on the outside of the hollow platform 584. The transmission device is located inside the mounting cavity and is connected to both the second motor 585 and the rotating frame 51. The second motor 585 drives the rotating frame 51 to rotate around the axial direction of the rotating frame 51 by driving the transmission device.

[0188] Optionally, the boss 56 is connected to the hollow platform 584, so that the hollow platform 584 can fix the boss 56 and prevent the boss 56 from rotating with the rotating frame 51.

[0189] Optionally, the hollow platform 584 has a circular cross-section to facilitate the cooperation between the hollow platform 584 and the second motor 585, the boss 56 and the transmission device.

[0190] Optionally, the hollow platform 584 is located below the rotating frame 51, and the lifting rod 581 is located below the hollow platform 584. The inoculation device 50 also includes a connector 586, which connects the boss 56 and the hollow platform 584. The connector 586 is positioned so that the boss 56 is located on one side of the rotating frame 51 in the circumferential direction, and the boss 56 protrudes from the circumferential side wall of the rotating frame 51.

[0191] Optionally, the hollow platform 584 is coaxially arranged with the rotating frame 51, and the outer diameter of the hollow platform 584 is smaller than the outer diameter of the rotating frame 51. The connecting member 586 includes a vertical plate segment and a horizontal plate segment connected together. The vertical plate segment extends vertically and is connected to the outer wall of the hollow platform 584. The horizontal plate segment is connected above the vertical plate segment and extends horizontally. The horizontal plate segment is located below the boss 56 and is connected to the boss 56. This enables the connection between the boss 56 and the hollow platform 584, and allows the boss 56 to be installed in a designated position.

[0192] Optionally, the mounting positions 511 of the rotating frame 51 include a first mounting position, a second mounting position, and a third mounting position. When the first mounting position corresponds to the inoculation station 602, the first mounting position is located between the second and third mounting positions. When the second mounting position corresponds to the inoculation station 602, the first mounting position corresponds to the sample extraction station 601, and the third mounting position corresponds to the sterilization station 604. When the first mounting position corresponds to the inoculation station 602, the protrusion 56 is located outside the first mounting position and protrudes beyond it. Optionally, the protrusion 56 is curved, and it curves towards the rotating frame 51. One end of the protrusion 56 extends to the side of the second mounting position facing the first mounting position, and the other end extends to the side of the third mounting position facing the first mounting position. This way, when the rotating frame 51 drives the inoculation loop 52 to rotate, the inoculation loop 52 located at the second mounting position will promptly contact the protrusion 56 after leaving the sample extraction station 601, causing the inoculation loop 52 to rotate towards the second position. Once rotated to inoculation station 602, the inoculation ring 52 can rotate into position. This allows the inoculation ring 52 a certain amount of time and distance to rotate from the first position to the second position, providing a buffer to prevent the inoculation ring 52 from suddenly lifting and causing damage. After inoculation is completed, the rotating frame 51 rotates, and the inoculation ring 52 can return to the first position along the boss 56, which also serves as a buffer to protect the inoculation ring 52.

[0193] Optionally, the width of the boss 56 gradually increases in the radial direction of the rotating frame 51 from both ends to the middle. This allows the inoculation ring 52 to gradually tilt as it moves from the first position to the second position, preventing it from moving too fast and being damaged. Similarly, this also ensures that the inoculation ring 52 has a certain buffer when moving from the second position to the first position, preventing damage to the inoculation ring 52.

[0194] Optionally, the radial width of the rotating frame 51 of the boss 56 is maximized at the position corresponding to the inoculation station 602, so as to ensure that the tilt angle is maximized when the inoculation ring 52 moves to the position corresponding to the inoculation station 602.

[0195] Optionally, the boss 56 is crescent-shaped.

[0196] Optionally, such as Figure 13As shown, the inoculation ring 52 includes an inoculation rod 521, an inoculation head 526, a clamping block 523, and an elastic element. The inoculation rod 521 is rotatably connected to the rotating frame 51, and one end of the inoculation rod 521 has a mounting groove. The inoculation head 526 is detachably connected to the mounting groove for operation with the operating station. The clamping block 523 is movably located in the mounting groove and has a first through hole. The side wall of the mounting groove has a corresponding second through hole 525, and the inoculation head 526 can be inserted into both the first and second through holes 525 simultaneously. The elastic element is connected to the clamping block 523. Between the clamping block 523 and the mounting groove; wherein, the clamping block 523 can move between a third position and a fourth position. When the clamping block 523 is in the third position, the inoculation head 526 is simultaneously inserted into the first through hole and the second through hole 525, the elastic element is in its original state, and the side wall of the first through hole limits the inoculation head 526 to prevent the inoculation head 526 from disengaging from the mounting groove; when the clamping block 523 is in the fourth position, the elastic element undergoes elastic deformation, and the side wall of the first through hole releases the limitation on the inoculation head 526, so that the inoculation head 526 can disengage from the mounting groove.

[0197] In this embodiment, the inoculation head 526 and the inoculation rod 521 are detachably connected, facilitating the replacement of the inoculation head 526 without replacing the entire inoculation ring 52. After the inoculation head 526 is inserted into the mounting groove, when no external force is applied to the clamping member, the elastic member is in its original state. The elastic member causes the clamping block 523 to be in the third position. At this time, the sidewall of the first through hole corresponds to the second through hole 525. The sidewall of the first through hole of the clamping block 523 can apply force to the inoculation head 526. The inoculation head 526 also passes through the second through hole 525 of the mounting groove. Thus, the clamping block 523 and the mounting groove can clamp the inoculation head 526, which is simultaneously located in the first and second through holes 525, thereby achieving the connection between the inoculation head 526 and the inoculation rod 521. When the inoculation head 526 needs to be removed, press the clamping member. The first through hole moves, causing its sidewall to move away from the second through hole 525. The sidewall of the first through hole no longer applies force to the inoculation head 526, thus releasing its restraint and allowing it to detach from the mounting slot. When the inoculation head 526 needs to be installed, press the clamping block 523. After inserting the inoculation head 526 into the first and second through holes 525, release the clamping block 523. The clamping block 523 will automatically clamp the inoculation head 526, enabling quick removal and replacement. This significantly improves installation and removal efficiency compared to methods like screw removal. Furthermore, the operation is simple, preventing improper installation of the inoculation ring 52 due to operator unfamiliarity with the mechanical structure, which could affect experimental results.

[0198] Optionally, the mounting groove includes a first groove wall and a second groove wall. The first groove wall faces the inoculation head 526, and the second groove wall is perpendicular to the first groove wall. The second groove wall has an opening, and the clamping block 523 is movably located at the opening. The first groove wall is formed in the second through hole 525.

[0199] Optionally, the system also includes a frame 104 located below the workbench and enclosing a cavity with the workbench 100. The cavity is used to place items or protect devices located below the workbench.

[0200] In some optional embodiments, the controller is configured to first control the movement of the liquid grabbing device and control the sample clamp to grab the sample container of the sample loading device 11, then move it to the sample scanning device for scanning, and then drive the sample container to be placed in the shaking tank (without shaking). After the sample container is opened, the sample clamp transfers the opened sample container to the sample transfer device 17, and the sample transfer device 17 transfers the sample container to the second area 102 and places it at the sample extraction station 601. The inoculation device 50 extracts the sample from the sample container. At the same time, the controller controls the culture dish loading device 21 to provide the culture dish 40 to the streaking device 23. After the culture dish 40 moves to the inoculation station 602, the controller controls the inoculation device 50 to extract the inoculation loop 52 of the sample and streak the culture dish 40. The streaked culture dish 40 is then transferred to the third area 103. The labeling structure of the sample collection component 30 labels the culture dish 40, and then the sample collection device 31 is controlled to collect the labeled culture dish 40. Alternatively, when the inoculation device 50 extracts the sample from the sample container, the controller controls the slide loading device 22 to control the slide to be dispensing, the slide is transferred to the tray, the inoculation device smears the slide, the smeared slide is placed on the moving platform for heating and then transferred to the slide receiving device. During the transfer process, the slide is marked with inkjet printing, and then the second pusher pushes the marked slide into the slide receiving device.

[0201] In some alternative embodiments, the controller is configured to first control the movement of the liquid-adding gripper and control the sample holder to grip the sample container of the sample loading device 11, then move it to the sample scanning device for scanning, then place the sample container in the shaking tank for shaking, and then place the heating device for heating and incubation. After incubation, the sample container is opened, and the opened sample container is transferred in the same manner as in the above embodiments, and used to make smears or streaks on a culture dish with a glass slide. Optionally, before sample shaking, the controller is configured to control the liquid-adding gripper to open the sample container first, then add digestion solution to the sample container before shaking and heating.
