The terms used herein in the specification of the template are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0027] In the related technology, in the preparation of assisted reproductive laboratories, the repetitive operation steps are: 1) Manual dish carving: technicians use scoring tools to mark the bottom or side of the culture dish for subsequent identification and tracking. The marking content may include the experiment date, sample number, patient information, etc., to ensure the uniqueness of each culture dish and the accuracy of the experimental records. 2) Manual dripping (pipetting): technicians use tools such as pipettes to accurately drip various reagents into the culture dish. These reagents may include culture fluid, washing fluid, thawing fluid, etc., which are used for the processing and cultivation of eggs, sperm and embryos. 3) Artificial covering oil (dripping oil): technicians use pipettes or special tools to carefully drip and spread the covering fluid on the surface of the culture fluid to ensure that it is uniform and does not affect embryonic development.

[0028] In the process of pipetting and dripping oil, most of the culture dishes are pipetted and dripped oil one by one and then immediately transferred to the incubator. Manual operation is cumbersome and it is not easy to ensure the stability and accuracy of the solution preparation effect.

[0029] like Figure 1 and Figure 5 As shown, in order to solve the above technical problems, the embodiment of the present application provides a liquid preparation system, which includes a workbench 500, a loading component 200, a scheduling component 600, a dripping component 400 and a unloading component 1400, the workbench 500 has a loading station 300, a dripping station and an unloading station 900; the loading component 200 is connected to the workbench 500, and the loading component 200 is used to transport the dish tray 1100 to the loading station 300; the scheduling component 600 is connected to the workbench 500 , the scheduling component 600 can grab and drive the dish tray 1100 to move within a preset range; wherein, the dripping station, the loading station 300 and the unloading station 900 are all located within the preset range; the dripping component 400 is connected to the workbench 500, and the dripping component 400 is used to sequentially drip culture solution and culture oil into the culture dish 1200 on the dish tray 1100 located at the dripping station; the unloading component 1400 is connected to the workbench 500, and the unloading component 1400 is used to store the dish tray 1100 located at the unloading station 900.

[0030] In these embodiments, the term "culture fluid, culture oil" should be understood in a broad sense, including various types of reagents involved in the preparation of fluids in assisted reproductive laboratories. The working process of the preparation system includes the following stages: Loading stage: The loading component 200 is responsible for automatically conveying blank or pre-processed dishes 1100 from the outside (such as a storage area) to the loading station 300 of the workbench 500. For example, the loading component 200 is provided with a conveyor belt; of course, in other embodiments, the loading component 200 is provided with a robot arm, etc., to replace manual handling, thereby reducing manual repetitive work.

[0031] Shifting to the dripping station: The scheduling component 600 is started, and the robot arm 410 or a suction cup or other device is used to accurately grab the dish tray 1100 of the loading station 300, and smoothly move it to the dripping station. The use of the robot ensures the accuracy and safety of the shifting process, and avoids errors and damages that may be introduced by manual operation.

[0032] Stage of dripping culture solution and culture oil: The dripping assembly 400 located at the dripping station is one of the cores of the system. It sequentially adds a preset amount of culture solution and culture oil to each culture dish 1200 through a precisely controlled pumping system or titration device. This automatic dripping process ensures the uniformity of each sample processing, which is crucial to the stability and accuracy of the experimental results.

[0033] Unloading stage: The scheduling component 600 moves the processed dishes 1100 from the dripping station to the unloading station 900, which is usually close to the subsequent processing equipment, or transfers the dishes 1100 from the unloading station 900 in batches to facilitate rapid transfer for subsequent operations. This process ensures that the processed dishes 1100 can quickly enter the next experimental stage, reducing waiting time and speeding up the experimental process.

[0034] By using the liquid preparation system provided by the present application, the entire system significantly speeds up the processing speed of the culture dish 1200 through automated operation, is suitable for batch processing, and greatly improves the automation level of the laboratory. Among them, automated instillation and transfer reduce the variables of manual operation, improve the stability and accuracy of the experimental results. In addition, the automated process reduces the manual labor of laboratory personnel and reduces the workload. In addition, each step is strictly performed in accordance with the preset parameters, ensuring the standardization and consistency of the experimental operation, which is conducive to the comparability and statistical analysis of the research data, and automation reduces the intervention of manual operation, reduces the possibility of external contamination, and provides a cleaner and more stable environment for the samples in the culture dish 1200.

[0035] like Figure 1 and Figure 4 As shown, in some embodiments, there are multiple dripping stations, and each dripping station is individually configured with a dripping component 400.

[0036] In these embodiments, by setting up a plurality of independent dripping stations in the liquid preparation system, each station is equipped with an independent dripping assembly 400, so that the entire system has parallel processing capabilities, further improving work efficiency.

[0037] In other words, since each dripping station can work independently, this means that the system can simultaneously perform dripping operations on multiple dishes 1100. This greatly improves processing efficiency and is particularly suitable for laboratories or production environments that need to process a large number of samples in a short period of time.

[0038] In addition, multiple dripping stations provide operational flexibility. The number of enabled dripping stations can be adjusted according to actual needs, which can not only cope with the large-scale sample processing during peak hours, but also flexibly adapt to small-scale operations during off-peak hours, thereby optimizing resource allocation. Obviously, if a dripping component 400 fails, other stations can still work normally, avoiding the situation where the entire system is shut down due to a single failure point, and ensuring the continuity of operations. At the same time, independent configuration allows maintenance and repairs to be carried out in a targeted manner without affecting the normal operation of other stations.

[0039] Among them, each dripping component 400 is independently controlled and can be personalized according to different types of experiments or sample requirements, such as adjusting the dripping volume, dripping speed, etc., to ensure that the dripping operation at each workstation can achieve the best effect and improve the stability and accuracy of the experimental results.

[0040] Exemplarily, the number of the dripping stations is 2; of course, in other embodiments, the number of the dripping stations is 3, 4, 5, 6, 7, 8, and so on.

[0041] like Figure 1 and Figure 4 As shown, in some embodiments, the loading component 200 includes a loading tray organizer 100, a loading platform 220 and a first transfer mechanism 210, and the lower end of the loading tray organizer 100 has a first inlet and outlet; the loading platform 220 is used to carry the dish tray 1100 sent out from the first inlet and outlet, and the first transfer mechanism 210 is connected to the loading platform 220, and the first transfer mechanism 210 can drive the loading platform 220 to move; wherein, the loading station 300 and the first inlet and outlet are located within the moving range of the loading platform 220.

[0042] In these embodiments, the loading tray sorter 100 is used as the starting point of the loading process. The loading tray sorter 100 stores a plurality of dish trays 1100. The loading tray sorter 100 is responsible for sorting and arranging the dish trays 1100 to be loaded, ensuring that they are ready to enter the system in a predetermined order and direction. Since the loading tray sorter 100 is a prior art, its working principle and structure will not be described in detail.

[0043] The first inlet and outlet at the lower end of the loading tray sorter 100 is the passage for the dish trays 1100 to enter the subsequent process, and the design needs to ensure that the dish trays 1100 can be sent out smoothly and accurately. The loading platform 220 serves as a dual role as a carrier and a transport carrier. The loading tray sorter 100 is used to carry the dish trays 1100 sent out from the loading tray sorter 100. The structure of the loading platform 220 needs to be stable, and it can safely support and move the loaded dish trays 1100, while ensuring that the position of the dish trays 1100 remains unchanged during the entire movement process to prevent tipping or collision.

[0044] Illustratively, one end of the loading platform 220 that carries the dish tray 1100 is a planar structure and is in a horizontal state.

[0045] The first transfer mechanism 210 is connected to the loading platform 220, and the first transfer mechanism 210 provides power to enable the loading platform 220 to move on a predetermined track. For example, the first transfer mechanism 210 includes a motor drive, a guide rail system or other forms of drive devices to ensure precise control and stability of movement, and is a key component for realizing automatic loading.

[0046] The loading station 300 and the first material inlet and outlet are positioned within the moving range of the loading platform 220, which means that the loading platform 220 can directly receive the dish trays 1100 from the loading tray sorting machine 100 and transport them to the loading station 300 without any additional complicated operations, thereby reducing the intermediate links, simplifying the operation process and improving efficiency.

[0047] Obviously, through automation and continuous material flow, the need for manual operation is significantly reduced, the loading process is accelerated, and the degree of automation is improved. In addition, the automated process reduces manual intervention, reduces the risk of operating errors and dish tray 1100 damage, and improves the stability of the experiment or production process.

[0048] Exemplarily, the first transfer mechanism 210 includes a first vertical lifting module and a first horizontal linear moving module, the first horizontal linear moving module is connected to the loading platform 220 through the first vertical lifting module, the first vertical lifting module is used to drive the loading platform 220 to lift vertically, and the first horizontal linear moving module is used to drive the loading platform 220 to move horizontally. When working, the loading platform 220 can be driven below the first inlet and outlet through the first horizontal linear moving module, and then the loading platform 220 is raised through the first vertical lifting module to contact the dish tray 1100 located at the first inlet and outlet, thereby completing the docking.

[0049] like Figure 1 and Figure 4 As shown, in some embodiments, the unloading component 1400 includes an unloading tray organizer 1000, an unloading loading platform and a second transfer mechanism, and the lower end of the unloading tray organizer 1000 has a second inlet and outlet; the unloading loading platform is used to carry the dish tray 1100 transported by the scheduling component 600, and the second transfer mechanism is connected to the unloading loading platform, and the second transfer mechanism can drive the unloading loading platform to move; wherein, the unloading station 900 and the second inlet and outlet are located within the moving range of the unloading loading platform.

[0050] In these embodiments, the unloading tray sorting machine 1000 is located at the end of the process, and is responsible for receiving the dish trays 1100 that have been treated with dripping liquid, and sorting and stacking them for use or storage in subsequent steps. The second inlet and outlet at the lower end is designed for the smooth feeding of the dish trays 1100, ensuring that the processed dish trays 1100 can be stacked and stored.

[0051] The unloading platform is similar to the loading platform 220, and is also responsible for carrying the dish trays 1100, but here it receives the processed dish trays 1100 transferred from the dripping station via the scheduling component 600. The unloading platform needs to have sufficient stability and carrying capacity.

[0052] The second transfer mechanism serves as a power source to drive the unloading loading platform to move. The second transfer mechanism is connected to the unloading loading platform to ensure that the loading platform carrying the dish tray 1100 can be accurately moved to the second inlet and outlet of the unloading tray sorting machine 1000 to complete the final delivery, stacking and storage steps.

[0053] Among them, the unloading station 900 and the second inlet and outlet are arranged within the moving range of the unloading loading platform. Such a layout design makes the entire unloading process seamless, reduces unnecessary operating steps and time, and improves work efficiency and space utilization.

[0054] Obviously, the automated process reduces manual intervention and speeds up the processing and transfer of the dish plate 1100, especially when processing a large number of samples. Automated transportation reduces the risk of physical damage to the dish plate 1100 during the processing and transfer process, thereby better protecting the safety of the sample.

[0055] For example, the second transfer mechanism includes a second vertical lifting module and a second horizontal linear moving module, the second horizontal linear moving module is connected to the unloading platform through the second vertical lifting module, the second vertical lifting module is used to drive the unloading platform to lift vertically, and the second horizontal linear moving module is used to drive the unloading platform to move horizontally. When working, the unloading platform can be driven below the second inlet and outlet of the unloading platform through the second horizontal linear moving module, and then the unloading platform is raised through the second vertical lifting module until the dish tray 1100 is pushed into the first inlet and outlet, thereby completing the docking.

[0056] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments, the workbench 500 further has a transfer station 800; The scheduling component 600 includes a loading and unloading clamp 650, a first drive mechanism 640, a second drive mechanism 630, a drop loading platform 610, and a third drive mechanism 620. The loading and unloading clamp 650 is used to clamp the dish plate 1100; the first drive mechanism 640 is connected to the loading and unloading clamp 650, and the first drive mechanism 640 can drive the loading and unloading clamp 650 to move in the first direction Z; the second drive mechanism 630 is connected to the first drive mechanism 640, and the second drive mechanism 630 can drive the loading and unloading clamp 650 to move in the second direction X; wherein the loading station 30 0 and the transfer station 800 are located within the moving range of the loading and unloading clamps 650; the dripping loading platform 610 is used to carry the dish 1100; the third driving mechanism 620 is connected to the dripping loading platform 610, and the third driving mechanism 620 can drive the dripping loading platform 610 to move along the third direction Y, and the dripping station and the transfer station 800 are located within the moving range of the dripping loading platform 610; wherein, one of the first direction Z and the second direction X is perpendicular to the horizontal plane, the other of the first direction Z and the second direction X is parallel to the horizontal plane, and the third direction Y is parallel to the horizontal plane.

[0057] In these embodiments, the workbench 500 and its integrated scheduling component 600 and drip loading platform 610 constitute a highly automated and flexible material handling and processing system.

[0058] The workbench 500 is not only provided with a loading station 300, a dripping station and a unloading station 900, but also with a transfer station 800. The loading and unloading clamps 650 of the scheduling component 600 are in direct contact with the dish tray 1100, and ensure the safe handling of the dish tray 1100 through precise clamping action. The combination of the first drive mechanism 640 and the second drive mechanism 630 enables the loading and unloading clamps 650 to move in a vertical direction (first direction Z) and a horizontal direction (second direction X), and the movement range of the loading and unloading clamps 650 covers the loading station 300 and the transfer station 800. This two-dimensional movement capability enables the loading process to be completed efficiently and accurately, whether the dish tray 1100 needs to be translated on a horizontal plane or lifted or lowered in a vertical direction.

[0059] The dripping loading platform 610 is used to carry the dish 1100 at the dripping station, receive the dish 1100 sent by the loading robot, and move in the horizontal direction under the action of the third driving mechanism 620. This ensures that the dish 1100 before and after the dripping operation can be stably transferred, and the dripping station and the transfer station 800 are both located within the movable range of the dripping loading platform 610, that is, the dish 1100 can be moved between the dripping station and the transfer station 800. The vertical and horizontal movement of the first driving mechanism 640 and the second driving mechanism 630 cooperate to enable the loading robot to perform all-round precise positioning on the workbench 500. The third driving mechanism 620 of the dripping loading platform 610 moves in the horizontal direction, which can realize the movement of the dripping loading platform 610 between the dripping station and the transfer station 800, and complete the movement of the dish 1100 between the dripping station and the transfer station 800.

[0060] For example, the first driving mechanism 640 is configured as a vertical linear motion module. Of course, the first linear motion mechanism can also be an electric push rod, a pneumatic cylinder, a hydraulic cylinder, etc.

[0061] Exemplarily, the second driving mechanism 630 is configured as a horizontal linear motion module. Of course, the second linear motion mechanism can also be an electric push rod, a pneumatic cylinder, a hydraulic cylinder, etc.

[0062] Exemplarily, the third driving mechanism 620 is configured as a horizontal linear motion module. Of course, the third linear motion mechanism can also be an electric push rod, a pneumatic cylinder, a hydraulic cylinder, etc.

[0063] Exemplarily, the angle between the third direction Y and the second direction X is set to 90°; of course, in other embodiments, the angle between the third direction Y and the second direction X is set to 40°, 50°, 60°, 70°, 80°, etc.

[0064] like Figure 1 and Figure 4 As shown, in some embodiments, the liquid preparation system also includes a waste bin 1300, which is connected to the workbench 500, and the waste bin 1300 has an open end, which is located at the dripping station; wherein an automatic sealing door is installed at the open end, and the dripping loading platform 610 located at the dripping station is located above the automatic sealing door.

[0065] In these embodiments, the waste bin 1300 is mainly used to collect waste that may be generated during the dripping operation, such as excess culture solution, culture oil dripping, or replaced dripping tips, etc. This helps to maintain a clean working environment and reduce the spread of pollutants, which is crucial to the hygiene standards and safety of the laboratory.

[0066] Among them, the open end of the waste bin 1300 is located at the dripping station, ensuring that the waste can directly fall into the waste bin 1300 after the dripping loading platform 610 removes the dripping station and the automatic blocking door is opened. Such a layout optimizes space utilization, does not occupy space, and is highly efficient. When the dripping loading platform 610 is in the dripping station, the dripping loading platform 610 can be temporarily located above the open end of the waste bin 1300. This clever design is to maintain the openness of the work area at non-waste collection times (such as when the dripping operation is in progress), avoiding interference or influence of the waste bin 1300 on the operation.

[0067] like Figure 2 and Figure 6 As shown, in some embodiments, the dripping assembly 400 includes a first pipette 420, a second pipette 430 and a robotic arm 410, the first pipette 420 is used to drip culture solution, and the second pipette 430 is used to drip culture oil; the execution end of the robotic arm 410 is respectively connected to the first pipette 420 and the second pipette 430, the robotic arm 410 can drive the first pipette 420 and the second pipette 430 to move, and the culture dish 1200 placed on the dish plate 1100 at the dripping station is within the moving range of the first pipette 420 and the second pipette 430.

[0068] In these embodiments, the system can independently and accurately control the dripping process of the culture solution and the culture oil by configuring the first pipette 420 and the second pipette 430. This design avoids the risk of cross contamination caused by frequent replacement of liquids with a single pipette, while improving the continuity and efficiency of the operation.

[0069] The mechanical arm 410 is a core actuator, and its execution end is connected to the first pipette 420 and the second pipette 430, which can accurately control the positioning and movement of the two in three-dimensional space. This design makes the dripping process not limited to simple linear movement, but also adapts to different layouts and positions of the culture dish 1200 in the dish tray 1100, thereby improving the flexibility and adaptability of the operation.

[0070] Exemplarily, the robot arm 410 is a six-axis robot arm 410; of course, in other embodiments, the robot arm 410 may also be set to a seven-axis robot arm 410, an eight-axis robot arm 410, and so on.

[0071] Furthermore, through careful layout, it is ensured that each culture dish 1200 on the dripping station is within the moving range of the first pipette 420 and the second pipette 430, and dripping can be completed accurately regardless of the arrangement of the culture dishes 1200 on the dish tray 1100. This requires the robot 410 to have high-precision positioning capabilities and the pipette head design to be able to adapt to culture dishes 1200 of different diameters and depths.

[0072] In specific operations, the robot arm 410 first accurately moves the first pipette 420 to the target culture dish 1200 according to a preset program or real-time instructions to complete the dripping of the culture solution, and then switches or moves the second pipette 430 to the culture dish 1200 at the same or different position to drip the culture oil. The whole process is fast, continuous and automated, which significantly improves the work efficiency when processing a large number of samples.

[0073] It should be noted that in actual use, the number of the first pipette 420 is not limited to one, and multiple pipettes may be provided according to actual use scenarios. For example, if multiple different liquids need to be dripped into the same culture dish 1200, multiple first pipettes 420 may be provided to drip multiple different liquids, which is more meaningful in actual dripping scenarios.

[0074] Obviously, through this highly automated and precisely controlled design, errors that may be introduced by manual operation, such as inaccurate volume and deviation in the dripping position, are almost eliminated, which is crucial to ensure the stability and accuracy of experimental results, especially in the fields of biomedicine and cell culture.

[0075] like Figure 6 As shown, in some embodiments, the drip assembly 400 also includes a fourth driving mechanism 440 and a fifth driving mechanism 450: the first pipette 420 is connected to the execution end of the robot arm 410 through the fourth driving mechanism 440, and the fourth driving mechanism 440 is used to drive the first pipette 420 away from or close to the execution end of the robot arm 410; the second pipette 430 is connected to the execution end of the robot arm 410 through the fifth driving mechanism 450, and the fifth driving mechanism 450 is used to drive the second pipette 430 away from or close to the execution end of the robot arm 410.

[0076] That is to say, during the dripping process, the fourth driving mechanism 440 can be used to drive the first pipette 420 to approach or move away from the culture dish 1200 located at the dripping station; and the fifth driving mechanism 450 can be used to drive the second pipette 430 to approach or move away from the culture dish 1200 located at the dripping station, so that the first pipette 420 and the second pipette 430 can be used to drip the culture solution and the culture oil successively, and the movement obstruction between the two can be avoided.

[0077] For example, when dripping culture solution, the fourth driving mechanism 440 is used to drive the first pipette 420 to approach the culture dish 1200, and the fifth driving mechanism 450 drives the second pipette 430 away from the culture dish 1200, thereby dripping culture solution; when dripping culture oil, the fourth driving mechanism 440 is used to drive the first pipette 420 away from the culture dish 1200, and the fifth driving mechanism 450 drives the second pipette 430 to approach the culture dish 1200, thereby dripping culture oil.

[0078] Exemplarily, the fourth driving mechanism 440 is configured as a horizontal linear motion module. In this embodiment, the fourth driving mechanism 440 includes a first rack, a first gear, and a first motor, and can use the first motor to drive the first gear, thereby driving the first pipette 420 connected to the first rack to rise and fall. Of course, in other embodiments, the fourth linear motion mechanism can also be an electric push rod, a pneumatic cylinder, a hydraulic cylinder, etc.

[0079] Exemplarily, the fifth driving mechanism 450 is configured as a horizontal linear motion module. In this embodiment, the fifth driving mechanism 450 includes a second rack, a second gear, and a second motor, and can use the second motor to drive the second gear, thereby driving the second pipette 430 connected to the second rack to rise and fall. Of course, in other embodiments, the fifth linear motion mechanism can also be an electric push rod, a pneumatic cylinder, a hydraulic cylinder, etc.

[0080] like Figure 6 As shown, in some embodiments, the drip assembly 400 also includes M cover opening mechanisms, M is a positive integer, and M≥1; wherein the cover opening mechanism includes a cover opening member 470 and a driving member 460, and the cover opening member 470 can grab the dish lid of the culture dish 1200; the execution end of the robotic arm 410 is connected to the cover opening member 470 through the driving member 460, and the driving member 460 is used to drive the cover opening member 470 away from or close to the execution end of the robotic arm 410.

[0081] In this embodiment, the dripping assembly 400 is provided with one cover opening mechanism as an example. That is, by utilizing the cover opening mechanism, the lid of the culture dish 1200 can be taken and placed, and the culture dish 1200 can be opened for dripping before dripping, and the lid can be closed after the dripping is completed. Of course, in other embodiments, the number of cover opening mechanisms can be increased accordingly according to the actual application scenario, for example, the number of cover opening mechanisms is two, and so on.

[0082] It is easy to understand that, by way of example, a specific working process includes the following steps: Step 1: Place the dish tray 1100 filled with culture dishes 1200 on the dripping station; Step 2: The driving member 460 drives the cover opening member 470 to move to contact the target culture dish 1200, and the cover opening member 470 grabs the dish cover and moves the dish cover; Step 3: Use the first pipette 420 and the second pipette 430 to drip the culture solution and culture oil into the body of the culture dish 1200, and then cover the body with a lid.

[0083] Exemplarily, the driving member 460 is a linear motion mechanism, such as an electric push rod, a pneumatic cylinder, a hydraulic cylinder, and the like.

[0084] For example, in this embodiment, the cover opening member 470 is a negative pressure suction cup. Of course, in other embodiments, it can also be set as an electric clamping claw, etc.

[0085] In some embodiments, the liquid preparation system also includes a cold chamber 700 and a temperature regulating member, the cold chamber 700 having an open end, the open end being detachably connected to a support portion, the support portion having a plurality of placement slots 710, the placement slots 710 being used to accommodate reagent bottles, and the reagent bottles placed in the placement slots 710 are located within the moving range of the first pipette 420 and the second pipette 430; the cold chamber 700 is connected to the temperature regulating member, and the temperature regulating member can adjust the temperature of the cold chamber 700.

[0086] In these embodiments, the liquid preparation system further enhances the management and processing capabilities of temperature-sensitive reagents by integrating a cold warehouse 700 and a temperature regulating member. The cold warehouse 700 is mainly used to store and keep the reagent bottles in a low temperature environment, especially for reagents that need to be stored at low temperatures to maintain stability (such as enzyme preparations, antibody solutions, etc.). In this embodiment, the reagent bottles are used to store culture fluid and culture oil respectively. Among them, the cold warehouse 700 is detachably connected to a support portion designed with multiple placement slots 710, which can accommodate a variety of different reagent bottles in an orderly manner, facilitate classified storage and quick access, and keep the laboratory desktop tidy and organized. The temperature regulating member is connected to the cold warehouse 700, and can accurately adjust the temperature inside the cold warehouse 700 to ensure that the reagents are stored under optimal conditions and avoid reagent activity loss or deterioration caused by temperature fluctuations. This is crucial to maintaining the chemical stability and biological activity of the reagents, as well as ensuring the stability and accuracy of the experimental results. At the same time, the placement slot 710 adopts an independent module design, and the support portion can be customized according to the shape, size and quantity of the container, which can be quickly disassembled and replaced, and has a wider range of applications.

[0087] It should be noted that the position of the reagent bottle placed in the cold chamber 700 is designed to be within the moving range of the first pipette 420 and the second pipette 430, which means that when necessary, the robotic arm 410 can directly take out the required reagents from the cold chamber 700 for pipetting operations without human intervention, which not only ensures the sterility of the operation, but also improves the experimental efficiency and reduces operational errors.

[0088] Obviously, through precise temperature regulation, the Cold Chamber 700 can operate efficiently and reduce energy waste. At the same time, the automated temperature control system can avoid temperature overshoot or overcooling caused by improper manual operation, ensuring the chemical stability and biological activity of the reagents.

[0089] In some embodiments, the temperature regulating element includes a semiconductor refrigerator and a power commutator, the semiconductor refrigerator has a heat conducting end, and the heat conducting end is connected to the cold chamber 700; the power commutator is electrically connected to the semiconductor refrigerator, and the power commutator is configured to at least be able to adjust the current direction of the current connected to the semiconductor refrigerator.

[0090] In these embodiments, the semiconductor refrigerator is used as a core component for temperature regulation of the cold chamber 700. It has a heat conducting end, which is in direct contact with the inside of the cold chamber 700. It produces hot and cold changes when powered on through the Peltier effect, thereby achieving the purpose of cooling or heating the environment inside the cold chamber 700. This design enables the cold chamber 700 to provide a stable low temperature or specific temperature environment for the reagent bottles placed inside it, ensuring the stability and activity of the reagents. The power commutator electrically connected to the semiconductor refrigerator is a key control unit. The semiconductor refrigerator can control the cooling or heating mode of the semiconductor refrigerator by changing the direction of the current. This means that the cold chamber 700 can not only maintain a low temperature environment, but also provide a heating function when necessary to adapt to a wider range of application requirements and environmental changes, greatly enhancing the flexibility and scope of application of the system.

[0091] Through intelligent regulation of the power inverter, the semiconductor cooler can quickly respond to the temperature setting and accurately control the temperature of the cold chamber 700. This instant temperature regulation capability is essential to maintain optimal storage conditions for sensitive reagents and helps improve the stability and accuracy of experimental results.

[0092] In some embodiments, the liquid preparation system also includes a first identification component, which is connected to the workbench 500, and the workbench 500 has a detection station. The first identification component can obtain and check the bottle body information of the reagent bottle located at the detection station; wherein the bottle body information includes one or more of the following: reagent type, batch number and expiration date.

[0093] In these embodiments, the reagent bottles are photographed to identify the type of the reagent bottles (i.e., the liquid contained in the reagent bottles) and the production batch information before being placed in the cold room 700. The positions of the above-mentioned placement slots 710 are limited, i.e., the reagent bottles containing culture fluid and the reagent bottles containing culture oil are placed in the placement slots 710 at the set positions, respectively, thereby ensuring that the first pipette 420 can accurately absorb the culture fluid and the second pipette 430 can accurately absorb the culture oil.

[0094] Thus, after the first identification component identifies the type of the reagent bottle, the third identification component is used to obtain and confirm whether the reagent bottle is placed in the correct position and the correct bottle opening state. If the placement is incorrect, the warning component will remind you.

[0095] Exemplarily, the first recognition component and the third recognition component are electrically connected to the controller respectively, and the warning component is electrically connected to the controller. Wherein, the first recognition component can be a camera module, the third recognition component can be a camera module, and the warning component can be a speaker, and of course, it can also be an alarm light.

[0096] In some embodiments, the liquid preparation system also includes a second identification component 1500, which is connected to the workbench 500 and is disposed above the loading station 300. The second identification component 1500 can obtain and check the dish body information of the culture dish 1200 located in the loading station 300; wherein the dish body information includes the engraving information and dripping information of the culture dish 1200.

[0097] During the dripping process, the second identification component 1500 will identify and verify the engraved dish information of the culture dish 1200, and record it, and then control the controller to drip the corresponding liquid into the culture dish 1200; during the unloading process of the culture dish 1200, the quality of the prepared liquid will be photographed and identified to confirm whether there are defects such as leakage, insufficient dripping, wrong dripping, and continuous dripping.

[0098] Exemplarily, the second identification component 1500 is electrically connected to the dripping component 400 via a controller.

[0099] Exemplarily, the second identification component 1500 may be a camera module.

[0100] It should be noted that the second identification component 1500 is connected to a driving module, and the driving module can drive the second identification component 1500 to move in a plane parallel to the dish plate 1100, thereby obtaining the information of each culture dish 1200 more accurately.

[0101] Alternatively, in other embodiments, the field of view of the second identification component 1500 is configured to cover the entire loading station 300. In this case, there is no need to set up a drive module.

[0102] In some embodiments, the liquid preparation system also includes a third identification component, which is connected to the workbench 500 and located above the workbench 500. The third identification component is used to obtain pictures and videos at the workbench 500, and the pictures are used to determine the presence and quantity of consumables, and the videos are used to subsequently trace the dripping and oil covering process.

[0103] As above, the third recognition component is located above the workbench 500 to achieve global monitoring, and can monitor the preparation process and the presence of consumables in real time, and retain information on the entire preparation process. Of course, the third recognition component can also give prompts through the warning component, such as voice prompts.

[0104] Exemplarily, the third identification component may be a camera module, whose field of view covers the entire workbench 500 .

[0105] In some embodiments, the liquid preparation system also includes a fourth identification component 1600, which is located above the unloading station 900. The fourth identification component 1600 is used to identify the engraving information and dripping information of the culture dish 1200 after dripping and covering oil in the unloading station 900, and determine whether the dripping effect is consistent with expectations through a visual algorithm.

[0106] That is to say, it is possible to identify the engraved dish information and the dripping information of the culture dish 1200 after the dripping and covering oil, and identify the shape of the droplets through an algorithm to obtain the quality of the dripping and covering oil.

[0107] Exemplarily, the fourth recognition component 1600 may be a camera module.

[0108] It should be noted that the fourth recognition component 1600 is connected to a driving module, and the driving module can drive the fourth recognition component 1600 to move in a plane parallel to the dish plate 1100, thereby obtaining the information of each culture dish 1200 more accurately.

[0109] Alternatively, in other embodiments, the field of view of the fourth identification component 1600 is configured to cover the entire unloading station 900. In this case, there is no need to set up a drive module.
