[0002] This application claims priority to Chinese patent application No. 202510070837.1, filed on January 16, 2025, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application relates to the field of battery technology, and in particular to a liquid injection system and its control method. Background Technology

[0004] In related technologies, during the research and development stage of electrolytes, the electrolyte injection system suffers from low injection efficiency. Summary of the Invention

[0005] In view of the above problems, this application provides a liquid injection system and its control method, which aims to improve the liquid injection efficiency during the research and development stage of electrolyte.

[0006] In a first aspect, this application provides a liquid injection system, including a workbench, a first liquid injection device, and a second liquid injection device. The workbench is provided with an injection station. The first liquid injection device is located on the workbench and is used to inject a target liquid into a preparation bottle located at the injection station. The second liquid injection device is located on the workbench and is used to inject the target liquid into the preparation bottle a second time, so that the preparation bottle reaches a target injection volume of the target liquid. The injection speed of the first injection is greater than the injection speed of the second injection.

[0007] The injection speed and injection accuracy of a liquid injection system are mutually restrictive. High-speed injection often reduces accuracy because a higher injection speed results in a larger liquid flow rate, and the dynamic characteristics of the liquid may lead to unstable flow, especially when the liquid viscosity is low or the pressure changes significantly. Conversely, a slower injection speed helps improve accuracy because a slower injection speed results in a smoother liquid flow, reducing liquid overflow or fluctuations. Based on this, this embodiment sets the injection speed of the first injection to be greater than that of the second injection. The high speed of the first injection device increases the injection speed of the entire system, achieving high-throughput injection. The high accuracy of the second injection device controls the injection accuracy of the entire system, achieving high-precision injection. Thus, by performing injection in two stages, both high-throughput and high-precision injection are achieved, improving injection efficiency.

[0008] In one embodiment, the injection volume of the first injection is greater than the injection volume of the second injection. This embodiment, by setting the injection volume of the first injection to be greater than the injection volume of the second injection, allows the high-speed first injection device to inject a larger volume, while the high-precision second injection device injects a smaller volume, thereby further reducing injection time and improving injection efficiency.

[0009] In one embodiment, the liquid injection system further includes a weighing device for weighing the preparation bottles placed thereon; the liquid injection station includes a first injection position and a second injection position; the weighing device is movably switchable between the first injection position and the second injection position on the worktable to drive the preparation bottles to switch between the first injection position and the second injection position; the first injection device is used to perform a primary injection of the target liquid into the preparation bottle at the first injection position; the second injection device is used to perform a secondary injection of the target liquid into the preparation bottle at the second injection position. This embodiment uses a weighing device to drive the preparation bottles to switch between the first injection position and the second injection position, completing a primary injection at the first injection position and a secondary injection at the second injection position, thus enabling the primary and secondary injections of the liquid injection system to proceed in an orderly manner, thereby improving the injection efficiency of the liquid injection system.

[0010] In one embodiment, the liquid injection system includes a conveying device for conveying injection bottles. The workbench has a liquid extraction position, and the conveying device has a first preset position corresponding to the liquid extraction position. The first liquid injection device includes a mounting bracket, a first moving device, and a liquid extraction device. The mounting bracket is located on the workbench. The first moving device is located on the mounting bracket and is used to move the injection bottle at the first preset position to the liquid extraction position. The liquid extraction device is located on the mounting bracket and is used to extract liquid from the injection bottle at the liquid extraction position according to the target injection volume and inject it into the configuration bottle at the first injection position. In this embodiment, by setting up the mounting bracket and the first moving device, the injection bottle is moved to the liquid extraction position outside the conveying device, thereby solving the problem that the injection bottle occupies the conveying device and affects the feeding of materials such as lithium salts during liquid injection operations, thus improving the working efficiency of the liquid injection system.

[0012] In this embodiment, the material bottle of the second injection device is fed by the first injection device. This ensures that the first and second injections use the same batch of raw material, reducing performance differences in the electrolyte caused by inconsistencies in the raw material and improving the consistency of electrolyte sample preparation. In one embodiment, the first moving device drives the injection bottle to reset from the extraction position to the first preset position. At the extraction position, the extraction needle of the extraction device passes through the injection bottle. At the first preset position, the injection bottle can flow on the conveying device.

For those skilled in the art, the specific meaning of the above terms in the embodiments of this application can be understood according to the specific circumstances.

[0089] With the continuous expansion of the battery market demand, the market has higher and higher requirements for battery performance. Electrolyte is known as the "blood" of the battery, and its performance directly affects the battery's energy density, cycle life, and charge-discharge performance. Among these, improving the performance of electrolyte through the research and development of electrolyte formulations is one of the ways to improve battery performance.

[0090] Due to the response time limitations of injection systems, high-throughput systems require large flow rates and low resistance, which can lead to unstable liquid flow and consequently low injection accuracy. High-precision systems, on the other hand, require finer flow control and micro-adjustments, often sacrificing flow rate and resulting in longer injection times and lower efficiency. During the electrolyte development phase, injection accuracy was prioritized over injection speed, and existing injection systems suffer from long injection times and low efficiency.

[0091] Based on this, this application proposes a novel liquid injection system, comprising a first liquid injection device and a second liquid injection device. The liquid injection speed of the first liquid injection device is greater than that of the second liquid injection device. The technical solution of this application achieves high-throughput liquid injection by increasing the liquid injection speed of the system through the high speed of the first liquid injection device, and high-precision liquid injection by controlling the liquid injection accuracy of the system through the high precision of the second liquid injection device. Thus, by performing liquid injection in two stages, both high-throughput and high-precision liquid injection are achieved, improving liquid injection efficiency. In the electrolyte development stage, rapid and high-precision electrolyte sample preparation allows for timely formula adjustments and shortens the development cycle.

[0092] The electrolyte injection system disclosed in this application is used in the research and development stage for sample preparation of electrolyte. Of course, it can also be used in the chemical industry, such as the preparation of chemical reaction ingredients, the pharmaceutical industry (preparation of drug solutions and injection solutions such as vaccines), the food and beverage industry, the coating and ink industry, etc., which will not be described in detail here.

[0093] For ease of understanding and explanation, in Figures 1 to 16 of this application, solid arrows indicate positions, slots, or holes.

[0094] According to some embodiments of this application, referring to FIG1, and further referring to FIG2, FIG10 and FIG12, the liquid injection system 1 includes a workbench 10, a first liquid injection device 11 and a second liquid injection device 12. The workbench 10 is provided with a liquid injection station. The first liquid injection device 11 is located on the workbench 10 and is used to inject the target liquid into the preparation bottle 17 located at the liquid injection station for a first time. The second liquid injection device 12 is located on the workbench 10 and is used to inject the target liquid into the preparation bottle 17 for a second time, so that the preparation bottle 17 reaches the target liquid injection volume. The injection speed of the first injection is greater than the injection speed of the second injection.

[0095] Workbench 10 refers to the operating platform used to support and fix the liquid being injected (such as solvents, additives, electrolytes, lubricating oils, or other liquids). The workbench 10 of the injection equipment is responsible for receiving, positioning, and fixing the items to be injected, and providing support for the injection process. Workbench 10 typically integrates multiple functions to enable liquids to be injected into designated containers or equipment according to preset requirements.

[0096] A liquid injection station is an operating position or work area in a production line or laboratory specifically used for injecting liquids. The main function of a liquid injection station is to provide a fixed operating position for injecting the target liquid.

[0097] A preparation bottle 17 is a bottle used in laboratories, industrial production, medical, and pharmaceutical fields to store and mix different chemicals or drugs. It is typically used to dissolve, dilute, mix, or prepare solutions to achieve specific concentrations or formulation requirements. In this embodiment, the preparation bottle 17 is used to mix and store electrolytes. Since electrolytes typically contain solvents and electrolytes, such as acids, salts, or alkalis, they are used in batteries, supercapacitors, or electroplating processes. The preparation bottle 17 requires high corrosion resistance in this environment because the chemicals in the electrolyte can corrode the container. Common materials for preparation bottles 17 include high-density polyethylene (HDPE) or acid-resistant glass.

[0098] The target liquid refers to the liquid used to prepare the electrolyte. This liquid can be liquid at room temperature or it can become liquid after heating or cooling, such as a solvent or additive. In other application scenarios, there are corresponding liquids.

[0099] The first liquid injection device 11 and the second liquid injection device 12 refer to automated devices used to inject liquid into containers, such as filling machines, liquid injection machines, or pipettes. The first liquid injection device 11 and the second liquid injection device 12 can be the same device. For example, the first liquid injection device 11 and the second liquid injection device 12 can be liquid injection machines, and the liquid injection speed of the two can be set to be different by the control device of the liquid injection system 1. The first liquid injection device 11 and the second liquid injection device 12 can also be different devices. For example, the first liquid injection device 11 is a liquid injection machine and the second liquid injection device 12 is a pipette. In this embodiment, the specific structure of the first liquid injection device 11 and the second liquid injection device 12 will be described in detail later.

[0100] The injection speed and injection accuracy of the injection system 1 are mutually restrictive. High-speed injection often reduces accuracy because when the injection speed is high, the liquid flow rate is high, and the dynamic characteristics of the liquid may lead to unstable flow, especially when the liquid viscosity is low or the pressure changes are large. On the other hand, a slower injection speed helps to improve accuracy because when the injection speed is slow, the liquid flow is more stable, thereby reducing liquid overflow or fluctuation.

[0101] Based on this, this embodiment sets the injection speed of the first injection to be greater than that of the second injection. The high speed of the first injection device 11 increases the injection speed of the injection system 1, achieving high-throughput injection. The high precision of the second injection device 12 controls the injection precision of the injection system 1, achieving high-precision injection. Thus, by performing injection in two stages, high-throughput and high-precision injection are achieved, improving injection efficiency.

[0102] In some embodiments, the injection volume of a single injection is greater than the injection volume of a second injection.

[0103] The injection volume refers to the volume or mass of liquid injected into the target container or device during the injection process. In this embodiment, it refers to the volume or mass of liquid injected into the target preparation bottle 17 during the injection process. The injection volume of a single injection is greater than the injection volume of a second injection. In this embodiment, the injection of a liquid is completed through two injections. That is, the injection volume of the liquid through the first injection device 11 in a single injection is greater than 50% of the total injection volume of the liquid. For example, it can be 51%, 52%, 53%, 54%, 55%, 60%, 62%, 65%, 66%, 68%, 70%, 72%, 75%, 78%, 80%, 83%, 85%, 86%, 88%, 90%, 92%, 95%, 96%, 97%, 98%, 99%, or 99.9%. Of course, in some embodiments, it can also be 99.99% or 99.999%.

[0104] In this embodiment, by setting the injection volume of the first injection to be greater than that of the second injection, the high-speed first injection device 11 can inject a larger volume of liquid, while the high-precision second injection device 12 can inject a smaller volume of liquid, thereby further reducing the injection time and improving the injection efficiency.

[0105] In some embodiments, referring to FIG4, the liquid injection system 1 further includes a weighing device 13, which is used to weigh the configuration bottle 17 placed thereon; the liquid injection station includes a first liquid injection position 10a and a second liquid injection position 10b; the weighing device 13 is movably and switchably disposed on the workbench 10 at the first liquid injection position 10a and the second liquid injection position 10b to drive the configuration bottle 17 to switch between the first liquid injection position 10a and the second liquid injection position 10b; the first liquid injection device 11 is used to perform a first liquid injection of the target liquid into the configuration bottle 17 at the first liquid injection position 10a; the second liquid injection device 12 is used to perform a second liquid injection of the target liquid into the configuration bottle 17 at the second liquid injection position 10b.

[0106] The weighing device 13 is used in the precise injection and proportioning process of liquid. In this embodiment, the weighing device 13 controls and monitors the amount of liquid added by accurately weighing the injected liquid, so that the liquid addition during the sample preparation process meets the set standards. The weighing device 13 is usually connected to an automated control system, has high precision and high stability, and can provide real-time feedback and adjust the injection volume. There are many types of weighing devices 13. Exemplarily, in this embodiment, the weighing device 13 generally monitors the weight change of the liquid in the preparation bottle 17 in real time through one or more load sensors (e.g., strain gauge load cells). These sensors convert the weight change into electrical signals and transmit them to the control system. The control system adjusts the liquid flow rate or on / off state according to the set target weight to control the accuracy of the injection process.

[0107] The first injection position 10a and the second injection position 10b refer to two preset positions on the machine platform. In this embodiment, two injection positions are set so that the injection of the first injection device 11 and the second injection device 12 is relatively independent, which can improve the flexibility of the injection system 1.

[0108] In this embodiment, since the diameter of the preparation bottle 17 is relatively small, the weighing device 13 drives the preparation bottle 17 to switch between the first injection position 10a and the second injection position 10b. One injection is completed at the first injection position 10a, and a second injection is completed at the second injection position 10b, so that the first and second injections of the injection system 1 are carried out in an orderly manner, thereby improving the injection efficiency of the injection system 1.

[0109] In some embodiments, referring to Figures 1 to 3, the liquid injection system 1 includes a conveying device 14 for conveying the liquid injection bottle 15. The workbench 10 has a liquid extraction position 10d, and the conveying device 14 has a first preset position 10c corresponding to the liquid extraction position 10d. The first liquid injection device 11 includes a mounting bracket 300, a first moving device 200, and a liquid extraction device 100. The mounting bracket 300 is located on the workbench 10. The first moving device 200 is located on the mounting bracket 300 and is used to move the liquid injection bottle 15 at the first preset position 10c to the liquid extraction position 10d. The liquid extraction device 100 is located on the mounting bracket 300 and is used to extract liquid from the liquid injection bottle 15 at the liquid extraction position 10d according to the target liquid injection volume and inject it into the configuration bottle 17 at the first liquid injection position 10a.

[0110] The conveying device 14 refers to a mechanical device used to transport materials from one place to another. The conveying device 14 can be a belt conveyor, chain conveyor, or conveyor rollers, etc. The injection bottle 15 is a container used for liquid injection or filling. In this embodiment, the injection bottle 15 is used to hold the electrolyte preparation stock solution (solvent or additives, etc.), and is typically made of glass or high-quality plastic (such as polyethylene, polypropylene, etc.), possessing good chemical stability and the characteristic of not easily reacting with drugs. In this embodiment, after the liquid in the injection bottle 15 is used up, it can return to the raw material storage area, etc., to replenish the injection bottle 15 through injection or other methods. After replenishment, it is transported again via the conveying device 14 and the first moving device 200 to the extraction position 10d for use by the extraction device 100.

[0111] The first preset position 10c refers to a preset position located on the conveying device 14, which is usually equipped with a positioning mechanism so that the injection bottle 15 can stop at this position when it is moved to it. The liquid extraction position 10d is a preset position located outside the conveying device 14. The liquid extraction position 10d can be set on the table surface of the workbench 10 or above the workbench 10; for example, as shown in Figures 1 and 2, the liquid extraction position 10d is set above the conveying device 14, which is also above the workbench 10.

[0112] The mounting bracket 300 is used to support the first moving device 200 and the liquid extraction device 100 so that the first moving device 200 and the liquid extraction device 100 are held in a predetermined position. The structure of the mounting bracket 300 will be described in detail later.

[0113] The first moving device 200 is used to move the injection bottle 15 from the first preset position 10c to the extraction position 10d. The first moving device 200 may move the injection bottle 15 horizontally to the extraction position 10d, lift it to the extraction position 10d, or lift it and then move it horizontally to the extraction position 10d, etc.

[0114] The liquid extraction device 100 is a device for extracting liquid from a container. In this embodiment, the liquid extraction device 100 is used to extract liquid from the injection bottle 15 at the extraction position 10d according to a target injection volume and inject it into the configuration bottle 17 at the first injection position 10a. Here, the target injection volume refers to the injection volume of a certain liquid in a single injection.

[0115] It is understandable that the preparation of electrolyte requires the addition of different types of solvents, additives and salt powder, etc. In other words, in this embodiment, while the conveying device 14 is transporting solvent, it must also meet the needs of other materials, such as salt powder, liquid injection bottle 15 and preparation bottle 17. The conveying device 14 is occupied during the liquid injection or liquid extraction cycle and cannot complete the feeding operation of other materials, thus reducing the overall efficiency.

[0116] In this embodiment, by setting up the mounting bracket 300 and the first moving device 200, the injection bottle 15 is moved to the liquid extraction position 10d outside the conveying device 14, thereby solving the problem that the injection bottle 15 occupies the conveying device 14 and affects the feeding of materials such as lithium salt during the injection operation, and thus improving the working efficiency of the injection system 1.

[0117] In some embodiments, the liquid extraction device 100 is used to extract liquid from the injection bottle 15 at the extraction position 10d according to the target injection volume, and to inject liquid into the reagent bottle 16 at the first injection position 10a.

[0118] Reagent bottle 16 refers to the material bottle of the second liquid injection device 12. The second liquid injection device 12 injects the liquid in reagent bottle 16 into preparation bottle 17 to complete the secondary liquid injection. In this embodiment, the liquid extraction device 100 is used to extract the liquid from the liquid injection bottle 15 at the extraction position 10d according to the target liquid injection volume, and to inject the liquid into the reagent bottle 16 at the first liquid injection position 10a to complete the feeding of reagent bottle 16.

[0119] The target injection volume generally refers to the maximum capacity of reagent bottle 16. Of course, this target injection volume can be set, and it is generally less than or equal to the maximum capacity of reagent bottle 16.

[0120] It is understandable that different batches of materials will have some differences in performance. In this embodiment, the material bottle of the second injection device 12 is fed by the first injection device 11. In this way, the same batch of raw material is used for the first and second injections, reducing the performance difference of the electrolyte caused by the inconsistency of the raw material and facilitating the improvement of the consistency of electrolyte preparation.

[0121] In some embodiments, please refer to Figures 1 to 3, the first moving device 200 is used to drive the injection bottle 15 to reset from the liquid extraction position 10d to the first preset position 10c; at the liquid extraction position 10d, the liquid extraction needle 110 of the liquid extraction device 100 passes through the injection bottle 15 at the liquid extraction position 10d; at the first preset position 10c, the injection bottle 15 can flow on the conveying device 14.

[0122] The first moving device 200 is used to drive the injection bottle 15 to reset from the liquid extraction position 10d to the first preset position 10c. Generally, this is automatically executed after at least one liquid in the injection bottle 15 has been used up. The first moving device 200 drives the injection bottle 15 to reset from the liquid extraction position 10d to the first preset position 10c. Of course, it can also be controlled by inputting a control command to control the first moving device 200 to reset the injection bottle 15 from the liquid extraction position 10d to the first preset position 10c.

[0123] In this embodiment, after the injection bottle 15 is reset from the liquid extraction position 10d to the first preset position 10c, it can automatically enter the next operation process (such as flowing to the next work station), reducing manual intervention and improving the automation level of the production line. Through automatic reset, the injection bottle 15 can quickly transition from the liquid extraction process to the flow process, reducing the pauses caused by waiting and manual handling, and improving the overall configuration efficiency.

[0124] In some embodiments, please refer to Figures 3 to 6. The first moving device 200 includes a first driving assembly 210 and a lifting frame 220. The first driving assembly 210 is disposed on the mounting bracket 300. The lifting frame 220 is disposed on the mounting bracket 300 and is used to lift the injection bottle 15. The lifting frame 220 is drivenly connected to the first driving assembly 210 to move the injection bottle 15 from the first preset position 10c to the liquid extraction position 10d, and to drive the injection bottle 15 to reset from the liquid extraction position 10d to the first preset position 10c.

[0125] The first drive assembly 210 is used to drive the lifting frame 220 to move the injection bottle 15 at the first preset position 10c to the liquid extraction position 10d and keep it at the liquid extraction position 10d. Any mechanism that can achieve this function is acceptable, such as a linear module mechanism, a motor gear mechanism, etc.

[0126] The lifting frame 220 is used to lift the injection bottle 15. It is understood that the injection bottle 15 is generally held and fixed by a tray or clamp. The lifting frame 220 is provided with a structure that is adapted to the tray or clamp for positioning, so as to complete the positioning of the injection bottle 15 and move the injection bottle 15 from the first preset position 10c to the liquid extraction position 10d.

[0127] In this embodiment, by setting up the lifting frame 220, the injection bottle 15 is lifted to the liquid extraction position 10d. By utilizing the upper space of the conveying device 14, the floor space of the injection system 1 can be reduced, which is conducive to the miniaturization of the injection system 1.

[0128] In some embodiments, please continue to refer to Figures 3 to 6. The mounting bracket 300 includes a bracket body 310, a first mounting plate 320 and a second mounting plate 330. The bracket body 310 is connected to the workbench 10. The first mounting plate 320 and the second mounting plate 330 are respectively disposed on the bracket body 310. The liquid extraction device 100 is disposed on the second mounting plate 330. The first drive assembly 210 is disposed on the first mounting plate 320. The first mounting plate 320 is provided with at least two slide rails 340. The lifting frame 220 is provided with at least two sliders 230. The at least two slide rails 340 and the at least two sliders 230 are slidably connected in a one-to-one correspondence.

[0129] The support body 310 is connected to the workbench 10 and mainly provides physical support for the liquid extraction device 100 and the first moving device 200.

[0130] A first mounting plate 320 is disposed on the bracket body 310, and a first drive assembly 210 is disposed on the first mounting plate 320. The first mounting plate 320 is provided with at least two slide rails 340, and the lifting frame 220 is provided with at least two sliders 230. The at least two slide rails 340 and the at least two sliders 230 are slidably connected in a one-to-one correspondence. The design of the first mounting plate 320 provides support, a mounting base, and flexible adjustment space for the lifting frame 220 and the first drive assembly 210. Through the cooperation of the at least two slide rails 340 and the sliders 230, the lifting frame 220 moves smoothly, improving the accuracy and stability of the equipment.

[0131] The second mounting plate 330 is on which the liquid extraction device 100 is mounted. The design of the second mounting plate 330 provides support, a mounting base and flexible adjustment space for the liquid extraction device 100.

[0132] In this embodiment, the first mounting plate 320 and the second mounting plate 330 are respectively mounted on the support body 310, the first moving device 200 is mounted on the first mounting plate 320, and the liquid extraction device 100 is mounted on the second mounting plate 330. This optimizes the spatial arrangement of the components of the first liquid injection device 11, disperses the load, improves the stability of each component of the liquid extraction device 100 and the first moving device 200, and reduces deformation or wear caused by excessive load. Secondly, the stability of the lifting frame 220 can be improved by setting at least two slide rails 340 and two sliders 230. The one-to-one correspondence between the at least two slide rails 340 and the sliders 230 allows the lifting frame 220 to be adjusted and moved within a certain range as needed to adapt to liquid bottles 15 of different heights and weights, thus enhancing the flexibility and adaptability of the first liquid injection device 11.

[0133] In some implementations, please refer to Figures 5 and 6. The support body 310 includes a base plate 311 and a support column 312. The base plate 311 is connected to the workbench 10. One end of the support column 312 is connected to the base plate 311, and the other end is connected to the second mounting plate 330. The first mounting plate 320 is disposed on the support column 312 and is located between the base plate 311 and the second mounting plate 330.

[0134] The base plate 311 is plate-shaped and is connected to the worktable 10. Compared with the support column 312 being directly connected to the worktable 10, the base plate 311 in this embodiment can reduce the installation difficulty and facilitate the integrated installation of the mounting bracket 300. The base plate 311 can be made of sheet metal through processes such as stamping and cutting.

[0135] Support column 312 serves as a vertical support element. Support column 312 can be made of a straight profile, and there are generally two of them. Of course, there can also be one, three or four. In some embodiments, auxiliary support columns are also included to improve the stability of the mounting bracket 300.

[0136] In this embodiment, the support body 310 is composed of a base plate 311 and a support column 312. The base plate 311 is connected to the workbench 10, providing a stable foundation for the entire device, making the equipment more stable during operation and reducing the impact of vibration or uneven load on the accuracy of the equipment.

[0137] In some implementations, please continue to refer to Figures 5 and 6. The first mounting plate 320 has a first side and a second side facing each other. The first drive assembly 210 is disposed on the first side of the first mounting plate 320, and at least two slide rails 340 are disposed on the second side of the first mounting plate 320. The lifting frame 220 includes a lifting plate 221, a lifting arm 222 disposed on the lifting plate 221, and a first connecting portion 223. At least two sliders 230 are disposed on the lifting plate 221. The first connecting portion 223 is located above the first mounting plate 320 and extends from the second side to the first side so that the first connecting portion 223 can be driven to connect with the first drive assembly 210.

[0138] The first side faces the conveying device 14, and the second side faces away from the conveying device 14. The first drive assembly 210 and the slide rail 340 are respectively mounted on the first and second sides of the first mounting plate 320. The arrangement of components is reasonable, reducing space occupation and improving the compactness and efficiency of the overall structure. The first connecting part 223 extends from the second side to the first side and connects to the first drive assembly 210. In this way, the drive assembly can effectively drive the lifting frame 220.

[0139] In this embodiment, the components of the mounting bracket 300 and the first moving device 200 are arranged in a reasonable manner, which reduces space occupation and improves the compactness and efficiency of the overall structure.

[0140] In some implementations, please refer to Figures 2, 3 and 7. The liquid extraction device 100 includes a liquid extraction assembly 101, which includes a liquid extraction needle 110 and a liquid extraction pump 120. The liquid extraction needle 110 is disposed on the second mounting plate 330 and is used to pass through the injection bottle 15 at the liquid extraction position 10d. The liquid extraction pump 120 has an inlet end and an outlet end. The inlet end of the liquid extraction pump 120 is connected to the liquid extraction needle 110 through a pipeline, and the inlet end of the liquid extraction pump 120 is connected to the configuration bottle 17 at the first injection position 10a through another pipeline.

[0141] The aspiration needle 110 is a liquid extraction tool used to insert into the injection bottle 15 at the aspiration position 10d. In this embodiment, some liquids have sealing requirements, so the port of the injection bottle 15 is usually provided with a sealing membrane, and the end is usually pointed to facilitate insertion into the injection bottle 15.

[0142] The liquid pump 120 primarily provides power to extract liquid from the injection bottle 15 at the injection position 10d. In some embodiments, the liquid pump 120 is also used to control the injection volume or reduce bubble precipitation. The liquid pump 120 can be a peristaltic pump, a plunger pump, a gear pump, or a pneumatic pump, etc.

[0143] The inlet end of the pump 120 is connected to the pump needle 110 via a pipeline, and the inlet end of the pump 120 is connected to the configuration bottle 17 at the first injection position 10a via another pipeline. In this way, the pumping position 10d and the injection position can be adjusted by changing the pipeline, and the pumping and delivery path of the liquid can be flexibly adjusted.

[0144] In this embodiment, by setting two pipelines to connect the liquid extraction needle 110 and the configuration bottle 17 respectively, the liquid extraction and delivery path can be flexibly adjusted, improving the versatility of the first liquid injection device 11.

[0145] In some implementations, please refer to Figures 2, 3, and 7. The second mounting plate 330 has a mounting hole 331 extending along its thickness. The aspiration needle 110 includes a first connector 113, a second connector 111, an elastic element 112, a sealing cap 114, and a needle tube 115. The first connector 113 is connected to the first connecting block 132. The second connector 111 has two opposing ends; one end of the second connector 111 is connected to the first connector 113, and the other end is confined within the mounting hole 331. The first connector 113 is movable along the extension direction of the mounting hole 331; the elastic member 112 is sleeved on the second connector 111, and the elastic member 112 is located between the second mounting plate 330 and the second connector 111; the sealing cap 114 is provided on the first connector 113 and is used to seal the mouth of the injection bottle 15; the needle 115 is provided on the first connector 113 and passes through the sealing cap 114, one end of the needle 115 is used to pass through the injection bottle 15, and the other end is connected to the pump 120 through a pipeline.

[0146] The first connecting member 113 is connected to the first connecting block 132. The first connecting member 113 serves as an intermediate connecting member, providing support for other components of the aspiration needle 110. The shape and structure of the first connecting member 113 are not limited. In one embodiment, the first connecting member 113 includes a first part and a second part arranged at an angle, which facilitates the movement of the needle tube 115 and the first vertical displacement mechanism 130, and also facilitates the connection of the second connecting member 111, the elastic member 112, the sealing cap 114, and the needle tube 115 to it. The second connecting member 111 can be a bolt, with one end of the bolt head directly positioned on the second mounting plate 330. A threaded hole is provided on the first connecting member 113, and the second connecting member 111 and the first connecting member 113 are connected by a threaded structure.

[0147] An elastic element 112, fitted onto the second connector 111, is located between the second mounting plate 330 and the second connector 111. It provides cushioning force to the first connector 113. The elastic element 112 is typically a spring, rubber ring, etc. A sealing cap 114, located on the first connector 113, is typically placed on the mouth of the injection bottle 15 after the syringe 115 is inserted into the appropriate position to meet the sealing requirements of some liquids. The syringe 115 is an instrument used for injecting or drawing liquids or gases. It typically consists of a long, thin tube and a sharp needle. The diameter and length of the tube can be selected according to different applications; common sizes include 1ml, 5ml, 10ml, 20ml, and 50ml. The needle is the sharp part of the syringe 115, usually made of stainless steel, and comes in different diameters and lengths to suit different injection or drawing needs.

[0148] In this embodiment, the needle tube 115 can move along the extension direction of the mounting hole 331 under the drive of the first connector 113, so that the liquid drawing needle 110 can extend and retract along the extension direction of the mounting hole 331, thereby enabling the liquid drawing device 100 to adapt to different liquid injection bottles 15 and improve the versatility of the first liquid injection device 11.

[0149] In some implementations, please continue to refer to Figures 2, 3 and 7. The liquid extraction assembly 101 also includes a first vertical displacement mechanism 130. The first vertical displacement mechanism 130 includes a first linear module 131 and a first connecting block 132. The first linear module 131 is disposed on the second mounting plate 330, the first connecting block 132 is disposed on the first linear module 131, and the liquid extraction needle 110 is disposed on the first connecting block 132. The first linear module 131 is used to drive the first connecting block 132 to move along the length direction of the first linear module 131, so as to drive the liquid extraction needle 110 to move along the length direction of the first linear module 131.

[0150] The first vertical displacement mechanism 130 has a main structure of a linear module, which is a mechanical mechanism that can provide linear motion. The linear module can provide high-precision and stable linear motion over a long distance, meeting the requirements for precision and repeatability in precision machining and automated production lines. It can realize fast and accurate material handling, inspection, assembly and other tasks, greatly improving production efficiency. The linear module can effectively save space.

[0151] The first linear module 131 typically includes a support frame, a guide rail system, a slider 230 or a slide block, a drive system, transmission components, and a limiting device. The support frame provides structural support for the entire system and is usually made of aluminum alloy or steel to ensure stable installation of the components and provide external protection. The guide rail system provides support and guidance, allowing the moving components to move along a linear trajectory. The guide rail can be a parallel linear guide or a ball bearing guide, featuring high precision and low friction. The slider 230 or slide block is mounted on the guide rail and slides or rolls freely along it. The slider 230 typically contains balls or sliding elements to reduce friction and improve motion accuracy and stability. The drive system is usually driven by an electric motor (such as a stepper motor or servo motor), using a belt, lead screw, or gear transmission method to make the slider 230 move linearly. The transmission components may use ball screws, belts, gears, or synchronous belts to connect the electric motor and the slider 230, converting the rotational motion of the electric motor into linear motion. The limiting device restricts the predetermined trajectory of the slider 230 and typically includes mechanical limits and electronic limits.

[0152] The function of the first connecting block 132 is to connect the aspiration needle 110 to the first linear module 131, thereby enabling the aspiration needle 110 to move vertically. The first connecting block 132 acts as an intermediary, facilitating the connection and relative movement between the first linear module 131 and the aspiration needle 110.

[0153] In this embodiment, the movement of the aspiration needle 110 in the vertical direction can be controlled by the cooperation of the first linear module 131 and the first connecting block 132 to adapt to the needs of different heights or positions. The setting of the first linear module 131 enables the aspiration needle 110 to move freely along its length, providing greater operating space and flexibility.

[0154] In some embodiments, please refer to Figures 2 and 3, there are multiple liquid extraction components 101, which are disposed on the second mounting plate 330 and located between the second mounting plate 330 and the base plate 311.

[0155] Multiple liquid extraction components 101 are located between the second mounting plate 330 and the base plate 311. The multiple liquid extraction components 101 are not only installed on the second mounting plate 330, but the overall arrangement of these liquid extraction components 101 is located within the space between the second mounting plate 330 and the base plate 311. That is, the working range of these liquid extraction components 101 is defined by the second mounting plate 330 and the base plate 311.

[0156] In this embodiment, multiple liquid extraction components 101 are centrally located between the second mounting plate 330 and the base plate 311, which helps to save space, make the equipment layout more compact, reduce the occupied area, and improve the overall space utilization of the equipment. The simultaneous operation of multiple liquid extraction components 101 can improve processing efficiency, adapt to diverse liquid extraction needs, and is suitable for process environments that require parallel processing, thereby increasing the system's production capacity.

[0157] In some embodiments, at least one needle tube 115 is provided with a first heating element. That is, among the plurality of needle tubes 115, one needle tube 115 may be provided with a first heating element, or two, three, four or more needle tubes may be provided with a first heating element, or all needle tubes 115 may be provided with a first heating element, and the first heating element may be activated when heating is required.

[0158] The first heating element refers to a component or device used for heating, which transfers heat to the target object or area to be heated by electricity, heat flow or other means. In this embodiment, the first heating element is usually a point-contact first heating element, mainly used for local heating. For example, the needle tube 115 is a point-contact heating needle.

[0159] This embodiment uses a first heating element on the syringe 115 to heat only the liquid that needs to be heated in the injection bottle 15, resulting in high energy utilization efficiency and reduced energy consumption.

[0160] In some embodiments, at least one pump 120 is a peristaltic pump. That is, among the plurality of pumps 120, one pump 120 may be a peristaltic pump, or two, three, four or more may all be peristaltic pumps, or all pumps 120 may be equipped with peristaltic pumps.

[0161] A peristaltic pump is a type of pump that delivers liquids or other fluids by sequentially pressing and releasing rollers or deflectors on a hose inside a pipe. Its working principle is similar to peristalsis (like the movement of a worm), where a series of rollers squeeze the hose, causing the liquid to move forward in the pipe.

[0162] In this embodiment, the pump 120 is a peristaltic pump. When using this pump, there is no direct contact between the liquid and the pump body; the liquid only contacts the inner wall pipe, which reduces cross-contamination and the introduction of contaminants. The peristaltic pump does not require valves and sealing devices like traditional pumps, reducing the risk of mechanical failure and simplifying maintenance. In addition, besides liquids, the peristaltic pump can also transport suspensions and liquids with high viscosity. Furthermore, the hose of the peristaltic pump is easy to replace, resulting in low maintenance costs.

[0163] In some embodiments, please refer to Figures 3, 8 and 9. The liquid injection system 1 further includes a first tray assembly 20, which has a receiving groove for fixing the liquid injection bottle 15. The first moving device 200 has a positioning part 224, and the first tray assembly 20 has a positioning hole 20d. The positioning part 224 is adapted to the positioning hole 20d for positioning connection.

[0164] The first tray assembly 20 is a fixture for fixing the injection bottle 15, which facilitates the flow of the injection bottle 15 in the conveying device 14. The first tray assembly 20 has many forms and structures. The first tray assembly 20 is used to accommodate and fix the injection bottle 15 so that the injection bottle 15 is not easily tilted or moved.

[0165] The first moving device 200 is provided with a positioning part 224, which is usually provided on the lifting arm 222. Of course, it can also be provided on the lifting plate 221, or the positioning part 224 can be provided on both the lifting arm 222 and the lifting plate 221.

[0166] The positioning hole 20d is used to cooperate with the positioning part 224 in the first moving device 200. When the first tray assembly 20 moves to the first preset position 10c, the first moving device 200 is inserted into the positioning hole 20d through the positioning part 224.

[0167] In this embodiment, by setting the positioning part 224 and the positioning hole 20d, it is possible to reduce the improper position or offset of the injection bottle 15 when it moves to the liquid extraction position 10d due to improper position or offset of the tray assembly, and reduce the probability of the liquid extraction needle 110 deviating when inserting into the injection bottle 15.

[0168] In some embodiments, please refer to Figures 8 and 9. The first tray assembly 20 includes a tray 21 and a heating box 22 disposed on the tray 21. The receiving slot includes a first receiving slot 20a and a second receiving slot 20b. The tray 21 is provided with the first receiving slot 20a, and the heating box 22 is provided with the second receiving slot 20b. The second receiving slot 20b is used to heat the liquid in the injection bottle 15 fixed therein.

[0169] The heating box 22 typically includes a box body and a second heating element disposed in the box body. For example, the heating box 22 includes an inner box and an outer box. The second heating element is typically disposed between the inner box and the outer box. The inner box defines the shape of the second receiving groove. The second heating element is used to heat the inner box and the space of the inner box. When the liquid bottle 15 is placed in the second receiving groove, the second heating element can heat the liquid in the liquid bottle 15.

[0170] The box body has an opening at the top, meaning that the box body has a bottom and sides, or only sides, with the bottom covered by a support plate 21. The second heating element can be located on the bottom of the box body or on a side of the box body. The box body has at least one side, and the second heating element is located on that at least one side. For example, when the box body is a square cylinder, that is, when the box body has four sides, the second heating element can be located on one side or on all four sides. The second heating element can be partially located on the four sides or the entire surface can be covered with the second heating element. In other words, the second receiving groove 20b is a surrounding heating groove, which has the effect of fast heating and uniform heating.

[0171] Since the raw materials for preparing the electrolyte usually include non-liquid materials at room temperature, these materials can be heated in the second container tank 20b and then extracted by the pumping device 100.

[0172] In this embodiment, by setting a second receiving tank 20b for heating the liquid in the injection bottle 15 fixed therein, non-liquid materials at room temperature can also be injected through the injection system 1, thereby improving the versatility of the injection system 1.

[0173] In some embodiments, please continue to refer to Figures 8 and 9. The first tray assembly 20 includes a limiting frame 23 disposed on the tray 21. The limiting frame 23 is located on one side of the heating box 22. The limiting frame 23 is provided with a limiting groove 20c corresponding to the first receiving groove 20a. The limiting groove 20c is used to limit the liquid injection bottle 15 disposed in the first receiving groove 20a.

[0174] The limiting frame 23 can be integrally formed or separately set. Since the injection bottle 15 has a certain height, and the thickness of the tray 21 cannot be too large, in order to reduce the tipping of the injection bottle 15, a limiting frame 23 is set on the tray 21. The limiting frame 23 has a limiting groove 20c corresponding to the first receiving groove 20a. When the injection bottle 15 is placed in the first receiving groove 20a, the injection bottle 15 passes through the limiting groove 20c. In this way, the setting of the limiting frame 23 can help reduce the probability of the injection bottle 15 placed in the first receiving groove 20a tipping over and reduce the impact of external disturbances on the position of the injection bottle 15.

[0175] In this embodiment, the limiting frame 23 is provided with a limiting groove 20c, which is used to limit the liquid injection bottle 15 located in the first receiving groove 20a. In this way, the limiting frame 23 can keep the liquid injection bottle 15 in a relatively fixed position, reducing the impact of external disturbances on the position of the liquid injection bottle 15.

[0176] In some embodiments, please continue to refer to Figures 8 and 9. The limiting frame 23 includes a limiting plate 23a and multiple limiting supports 23b. The limiting plate 23a and the support plate 21 are stacked. The multiple limiting supports 23b are respectively connected between the limiting plate 23a and the support plate 21. The limiting groove 20c is provided at the position of the limiting plate 23a corresponding to the first receiving groove 20a.

[0177] The limiting plate 23a is usually a thin plate, for example, a plate of 5mm to 20mm. Through processes such as stamping and cutting, a through groove is punched out along the thickness direction of the limiting plate 23a. This through groove is the limiting groove 20c.

[0178] Limiting strut 23b is usually a connecting rod. The number of limiting struts 23b is generally two or more, which can be two, three, four, five, six, eight or more. Of course, the number of limiting struts 23b should not be too many.

[0179] In this embodiment, the limiting frame 23 includes a limiting plate 23a and multiple limiting supports 23b. This structure of the limiting frame 23 can reduce the weight of the limiting frame 23.

[0180] In some embodiments, please refer to FIG4, and further refer to FIG1 to FIG3, the first liquid injection device 11 includes a liquid injection terminal 140, the liquid injection terminal 140 is located at the first liquid injection position 10a of the workbench 10, the liquid injection terminal 140 is provided with a plurality of liquid injection ports 141, and the plurality of liquid injection ports 141 are connected one-to-one with the outlet ends of a plurality of liquid pumps 120.

[0181] The injection terminal 140 is located at the position of the first injection device 11 closest to the dispensing bottle 17 on the injection flow path. The injection terminal 140 includes a mounting base and an injection head disposed on the mounting base. The mounting base has a mounting portion for mounting the injection head and a slot for fixing the connecting pipeline. An injection port 141 is disposed on the injection head. The injection port 141 may be designed in different shapes and sizes to adapt to different types of containers or conveying requirements. Common types of injection ports 141 include threaded connections, snap-fit ​​connections, and quick couplings.

[0182] The injection terminal 140 is equipped with multiple injection ports 141. Each injection port 141 can be connected to the outlet of the pump 120 via a connecting pipe. The multiple injection ports 141 allow different liquids or different containers to be dispensed using different combinations of pumps 120 and injection ports 141, increasing the system's flexibility and scalability. Secondly, the connection of each injection port 141 to an independent pump 120 reduces cross-contamination between different liquids. Furthermore, the connection of each injection port 141 to an independent pump 120 allows for independent control of the liquid delivery at each injection port 141. Thus, the flow rate and pressure of each injection port 141 can be adjusted as needed according to different liquids or different injection requirements, thereby improving injection accuracy.

[0183] In this embodiment, the injection terminal 140 is provided with multiple injection ports 141, and each injection port 141 corresponds to one of the outlets of multiple pumps 120, which increases the flexibility and scalability of the system.

[0184] In some embodiments, multiple injection ports 141 correspond one-to-one with the outlets of multiple pumps 120, enabling multiple liquids to be injected into different locations or containers simultaneously, thereby achieving parallel operation and improving injection efficiency.

[0185] In some embodiments, please refer to FIG2, and further refer to FIG1 and FIG3, the first liquid injection device 11 further includes a heat preservation component 400, which is disposed between the second mounting plate 330 and the liquid injection terminal 140; the heat preservation component 400 is provided with a heat preservation channel, and the connecting pipe between the liquid injection bottle 15 located in the second receiving tank 20b and the liquid injection terminal 140 is disposed in the heat preservation channel.

[0186] The core function of the insulation component 400 is thermal insulation, used to reduce heat loss to the outside or heat entry from the outside. Whether for heating or cooling, the insulation component 400 helps maintain a stable internal temperature for the equipment. The insulation component 400 can consist of only an insulation layer or include both an insulation layer and a temperature regulating component. The insulation layer is typically made of insulating materials (such as polyurethane, rock wool, glass wool, etc.) and is used to wrap the equipment or pipes, effectively insulating them from external heat or cold and reducing heat loss. The temperature regulating component can be a heating or cooling element. It engages when the insulation layer cannot maintain a stable temperature within the insulation channel at the preset temperature, thereby maintaining the temperature within the insulation channel at the preset temperature.

[0187] Because there is a close relationship between the viscosity of a liquid and its temperature, the viscosity of a liquid usually changes with temperature. For most liquids (especially Newtonian fluids), the viscosity decreases when the temperature increases and increases when the temperature decreases.

[0188] This embodiment provides a relatively stable temperature insulation channel by setting the insulation component 400, so that the non-liquid material at room temperature can maintain a relatively stable viscosity during the liquid injection process, thereby improving the liquid injection accuracy of the first liquid injection device 11 for non-liquid materials at room temperature.

[0189] In some embodiments, referring to FIG10 and further referring to FIG4, FIG12 to FIG15, the workbench 10 is provided with a first storage area 10e and a second dispensing position 10b. The first storage area 10e is used to store reagent bottles 16. The second dispensing device 12 includes a second moving device 500, a clamping device 600 and a pipetting device 700. The second moving device 500 is disposed on the workbench 10; the clamping device 600 is used to clamp the reagent bottles 16 and is disposed on the second moving device 500. The clamping device 600 is moved to allow the reagent bottle 16 to be transferred between the first storage area 10e and the second dispensing position 10b; the pipetting device 700 is provided on the second moving device 500, which is used to move the pipetting device 700 to the first storage area 10e to draw liquid from the reagent bottle 16 in that area according to the target dispensing volume, and to the second dispensing position 10b to inject the drawn liquid into the dispensing bottle 17 in the second dispensing position 10b.

[0190] The first storage area 10e refers to a preset position on the machine platform, which is used to store reagent bottles 16.

[0191] The second moving device 500, capable of moving within a preset range, firstly needs to enable the second moving device 500 to drive the clamping device 600 to move between the first storage area 10e and the second injection position 10b. Of course, it also needs to be able to move to other positions within the preset range. For example, the second moving device 500 is a robotic arm or a moving platform.

[0192] A clamping device 600 is used to grasp, hold, and release objects, thereby enabling the handling, assembly, inspection, or other operations of items. The clamping device 600 typically consists of multiple components, including a mechanical clamping part 622, an electric actuator, sensors, etc., and can control the clamping action in various ways as needed. Exemplarily, the clamping device 600 is a pneumatic gripper 620, an electric gripper 620, or a hydraulic gripper 620, etc. In this embodiment, the clamping device 600 can be used to grasp, fix, transport, or release reagent bottle 16, or the clamping device 600 can be used to grasp, fix, transport, or release preparation bottle 17. Of course, in other embodiments of this application, the clamping device 600 is used to grasp, fix, transport, or release the cap of reagent bottle 16, thereby opening or closing reagent bottle 16.

[0193] The pipetting device 700 is a device capable of aspirating and storing liquid therein, and of discharging the liquid stored in the pipetting device in a preset manner; that is, a device capable of aspirating, storing and discharging liquid. For example, the pipetting device 700 is an electronic pipette.

[0194] In this embodiment, by integrating the clamping device 600 and the pipetting device 700 into a single mobile device, the number of devices can be reduced, space in the laboratory or production environment can be saved, and the manufacturing cost of the second dispensing device 12 can be reduced.

[0195] In some embodiments, referring to FIG12 and further to FIGS13 to 15, the second moving device 500 includes an X-axis displacement mechanism 510, a Y-axis displacement mechanism 520, a Z-axis displacement mechanism 530, and a connecting bracket 540. The X-axis displacement mechanisms are disposed on the worktable 10; the Y-axis displacement mechanism 520 is disposed on the X-axis displacement mechanism 510 and can move along the length direction of the X-axis displacement mechanism 510; the Z-axis displacement mechanism 530 is disposed on the Y-axis displacement mechanism 520 and can move along the length direction of the Y-axis displacement mechanism 520; the connecting bracket 540 is disposed on the Z-axis displacement mechanism 530, and the clamping device 600 and the pipetting device 700 are disposed on the connecting bracket 540.

[0196] The X-axis displacement mechanism 510, Y-axis displacement mechanism 520, and Z-axis displacement mechanism 530 can be linear modules, ball screw mechanisms, belt drive mechanisms, pneumatic / hydraulic cylinder mechanisms, etc.

[0197] For example, the X-axis displacement mechanism 510, Y-axis displacement mechanism 520, and Z-axis displacement mechanism 530 are linear modules. Thus, the X-axis displacement mechanism 510, Y-axis displacement mechanism 520, and Z-axis displacement mechanism 530 form an XYZ three-axis combined displacement stage. The X-axis displacement mechanism 510 typically controls the horizontal movement of the connecting bracket 540, moving it horizontally. The Y-axis displacement mechanism 520 typically controls the longitudinal movement, moving it horizontally and perpendicular to the X-axis. In this embodiment, the connecting bracket 540 is mounted on the Z-axis displacement mechanism 530, which controls vertical movement. The Z-axis displacement mechanism 530 is mounted on the Y-axis mechanism.

[0198] In the X-axis displacement mechanism 510, Y-axis displacement mechanism 520 and Z-axis displacement mechanism 530, each displacement mechanism is usually equipped with an independent drive device (e.g., stepper motor, servo motor, linear motor, etc.), a guide system (the guide system is used to control the platform to move smoothly in the corresponding direction, and usually uses components such as ball screws, rollers, linear guides 340 to provide guidance), a feedback system (e.g., encoders, linear sensors, etc., used to monitor and provide feedback on the position information of the platform in real time), and a control system (usually composed of PLC, motion control card or computer, etc., used to coordinate and control the movement of the three axes).

[0199] The connecting bracket 540 is a mounting component. After the clamping device 600 and the pipetting device 700 are integrated by the connecting bracket 540, they are then installed on the second moving device 500, which facilitates the installation of the clamping device 600 and the pipetting device 700.

[0200] In this embodiment, the clamping device 600 and the pipetting device 700 are integrated by the connecting bracket 540 and then installed on the second moving device 500, which facilitates the installation of the clamping device 600 and the pipetting device 700. Through three displacement mechanisms with mutually perpendicular movement directions, the clamping device 600 and the pipetting device 700 are driven to switch between multiple preset positions. The movement of each displacement mechanism is usually controlled by an independent drive system. They can work together to achieve three-dimensional positioning.

[0201] In some embodiments, please refer to FIG13, the Z-axis displacement mechanism 530 includes a second linear module 531 and a second connecting block 532 disposed on the second linear module 531, the second connecting block 532 being connected to the Y-axis displacement mechanism 520; the connecting bracket 540 includes a first connecting plate 541 and a second connecting plate 542; the first connecting plate 541 is disposed on the connecting block, the pipetting device 700 is disposed on the first connecting plate 541, the second connecting plate 542 is disposed on the first linear module 131, and the clamping device 600 is disposed on the second connecting plate 542.

[0202] The connecting bracket 540 includes a first connecting plate 541 and a second connecting plate 542, wherein the first connecting plate 541 and the second connecting plate 542 are independently arranged. In embodiments where the first connecting plate 541 and the second connecting plate 542 are independently arranged, it is convenient to adjust the connection position of the pipetting device 700 and the clamping device 600, thereby improving the installation flexibility and versatility of the second liquid injection device 12. In other embodiments, the first connecting plate 541 and the second connecting plate 542 may be connected or installed together.

[0203] This embodiment, by separating the connecting bracket 540, facilitates the adjustment of the connection position between the pipetting device 700 and the clamping device 600, thereby improving the installation flexibility and versatility of the second injection device 12.

[0204] In some embodiments, referring to FIG13, the connecting bracket 540 further includes a third connecting plate 543, which is connected to the second linear module 531 and the second connecting block 532. The third connecting plate 543 extends along the length direction of the second linear module 531. The third connecting plate 543 has a first end and a second end that are disposed opposite to each other along the length direction of the second linear module 531. The first end of the third connecting plate 543 is close to the worktable 10. The first connecting plate 541 is connected to the first end of the third connecting plate 543, and the second connecting block 532 is connected to the second end of the third connecting plate 543.

[0205] The third connecting plate 543 is also a connector. By setting the third connecting plate 543, it is convenient to install the second linear module 531 and the pipetting device 700, and the second linear module 531 and the Y-axis displacement mechanism 520. This way, the pipetting device 700 and the Y-axis displacement mechanism 520 are not directly on the second linear module 531, which can reduce the stress points of the second linear module 531.

[0206] In this embodiment, by adding a third connecting plate 543 and extending it along the length of the second straight module 531, the rigidity and stability of the entire connecting bracket 540 can be improved. The two ends of the third connecting plate 543 are connected to the first connecting plate 541 and the second connecting block 532 respectively, making the overall structure more compact and evenly distributed with stress, reducing possible twisting or deformation. In addition, the entire structure is more flexible and convenient to install and adjust.

[0207] In some embodiments, referring to FIG14, the clamping device 600 includes a second drive assembly 610 and at least two grippers 620. The second drive assembly 610 is used to drive the at least two grippers 620 to move closer to each other, or the second drive assembly 610 is used to drive the at least two grippers 620 to move further apart from each other. Each gripper 620 includes a second connecting portion 621, a clamping portion 622, and a gripping finger 623. The second connecting portion 621 is drivenly connected to the second drive assembly 610. The clamping portion 622 is disposed on the second connecting portion 621, and an anti-slip portion 624 is provided on the inner side of the clamping portion 622. The gripping finger 623 is disposed at one end of the clamping portion 622 away from the second connecting portion 621.

[0208] The clamping device 600 is a mechanical device, usually installed at the end of a robot or automated equipment, for gripping, fixing, transporting or releasing workpieces. In this embodiment, the clamping device 600 is used to grip, fix, transport or release reagent bottle 16. Of course, in this application, the clamping device 600 can also be used to grip preparation bottle 17.

[0209] The clamping part 622 has an anti-slip part 624 on its inner side. "Inner side" refers to the side of the grippers 620 where the two grippers 620 are close to each other. The anti-slip part 624 can be of many types; it can be a protrusion or ridge on the inner wall of the clamping part 622, or the inner wall of the clamping part 622 may be uneven. For example, the anti-slip part 624 can be multiple ridges on the inner wall of the clamping part 622, arranged at intervals along the circumference of the clamping part 622, extending from the second connecting part 621 toward the gripper finger 623.

[0210] In this embodiment, the anti-slip part 624 on the inner side of the clamping part 622 can provide better friction when the gripper 620 contacts the workpiece, reducing the risk of slippage or loosening, thereby enhancing the clamping effect. In addition, the design of the anti-slip part 624 allows the gripper 620 to better adapt to different materials or surface properties when clamping objects, thereby improving the clamping force.

[0211] In some embodiments, referring to FIG13, the workbench 10 is provided with a second dispensing position 10b, a first storage area 10e, a second storage area 10f, and a third storage area 10h. The first storage area 10e is used to store reagent bottles 16, the second storage area 10f is used to store pipette tips 18 to be used, and the third storage area 10h is used to store used pipette tips 18. The pipetting device 700 includes a device body 710 and a pipetting head 720. The device body 710 is disposed on the first connecting plate 541; the pipetting head 720 is disposed on the device body 710 and connected to the device body 710. Drive connection; the device body 710 is used to drive the pipette head 720 to dock with the pipette tip 18 in the second storage area 10f, the device body 710 is used to drive the pipette head 720 to move so that the pipette tip 18 can extend into the reagent bottle 16 in the first storage area 10e, the device body 710 is used to drive the pipette head 720 to draw liquid from the reagent bottle 16 in the first storage area 10e according to the target dispensing volume and store it in the pipette tip 18; the device body 710 is also used to drive the pipette head 720 to release the liquid in the pipette tip 18 to inject into the preparation bottle 17 in the second dispensing position 10b.

[0212] The main body 710 is the core structure of this pipetting device 700. Its primary function is to drive the pipetting head 720 to perform liquid transfer operations. These operations include docking the pipetting head 720 with the pipette tip 18, aspirating liquid from the reagent bottle 16, storing the liquid in the pipette tip 18, and releasing the liquid into the preparation bottle 17. The main body 710 mainly includes a drive assembly and a control assembly. The control assembly is communicatively connected to the control device of the dispensing system 1 and controls the drive assembly to drive the pipetting head 720 to perform operations according to the set target dispensing volume.

[0213] The pipette tip 720 is a component connected to and driven by the device body 710, typically consisting of a connector, a liquid delivery channel, and a connector that drives the device body 710. The main function of the pipette tip 720 is to work in conjunction with the device body 710. After being installed and mated with the pipette tip 18, the pipette tip 720 performs liquid aspiration and injection operations. The pipette tip 720 is moved by the drive system, inserting the pipette tip 18 into the reagent bottle 16 to aspirate liquid and store it within the pipette tip 18. Then, as needed, the liquid is precisely injected into the target preparation bottle 17.

[0214] In this embodiment, the main body 710 can automatically drive the pipette head 720 to dock with the pipette tip 18 and perform liquid transfer, eliminating the need for manual operation and increasing the liquid transfer speed in the experiment, thereby improving the injection speed of secondary liquid injection; in addition, the automated drive and control mechanism reduces human intervention, making the liquid transfer process more stable and consistent, and improving the injection accuracy of secondary liquid injection.

[0215] In some embodiments, referring to Figures 1 to 4 and Figures 10 to 12, the liquid injection system 1 includes a control device. The control device receives target formulation information and determines the type and dosage of the target liquid based on the target formulation information. The control device receives the identity information and location information of the injection bottle 15 at the liquid extraction location 10d, and determines the target injection bottle 15 based on the type of the target liquid, the identity information of the injection bottle 15, and the location information of the injection bottle 15. The control device receives the location information and identity information of the reagent bottle 16, and determines the target reagent bottle 16 based on the type of the target liquid, the location information of the reagent bottle 16, and the identity information of the reagent bottle 16. The control device receives the identity information of the configuration bottle 17 at the liquid injection station and controls the device to... The device is used to associate the identity information of the preparation bottle 17 with the target formula information and confirm it as the target preparation bottle 17; the control device is used to complete the injection according to the type of target liquid, wherein the injection process of at least one type is as follows: the control device is used to determine the first target injection volume and the first injection speed of the first injection device 11 according to the performance and dosage of the target liquid, and to determine the second target injection volume and the second injection speed of the second injection device 12; the control device is used to control the first injection device 11 to draw the liquid from the target injection bottle 15 according to the first target injection volume and inject the liquid into the target preparation bottle 17 according to the first injection speed, and to control the second injection device 12 to draw the liquid from the target reagent bottle 16 according to the second target injection volume and inject the liquid into the target preparation bottle 17 according to the second injection speed.

[0216] The control device is one of the components used to regulate, manage, and monitor the entire liquid injection process. It typically consists of a control unit, sensors, and a user interface. In this embodiment, the control device controls the actions of the pipette head 720 or other actuators such as the pump based on set parameters (such as injection volume, speed, and position), thereby achieving automated, high-throughput, and high-precision liquid transfer.

[0217] The control unit, including a microprocessor, memory, and input / output interfaces, is flexible and scalable, and can adjust its operating mode according to different injection requirements. As the brain of the control system, the control unit receives feedback signals from sensors and issues commands based on user input or preset programs, driving the various components in the injection system 1 (such as the first injection device 11 and the second injection device 12) to perform corresponding actions. It typically has real-time calculation and adjustment capabilities, enabling it to dynamically adjust the injection speed, volume, and position of the liquid as needed.

[0218] A sensor system is used to monitor the state of a liquid or parameters during the injection process in real time, such as liquid volume, injection rate, air pressure, and temperature. The sensors transmit these data to the control device for real-time adjustment and optimization control. A sensor system typically includes volume sensors, flow sensors, pressure sensors, position sensors, and temperature sensors.

[0219] The user interface is used to display system status, operation instructions, and injection parameter settings. Operators can set the target liquid volume, injection speed, mode selection, etc. through the interface and monitor the system's operating status in real time. The user interface is usually a touch screen, keypad, or computer interface.

[0220] The automatic calibration system is used to improve the injection accuracy of the injection system 1. The system can automatically calibrate to improve the accuracy of injection volume, flow rate and position, and reduce errors caused by operation error or equipment aging. The automatic calibration system automatically adjusts the liquid injection volume and speed through sensors and feedback mechanisms.

[0221] Feedback control systems monitor the liquid transfer status in real time, compare actual parameters with set targets, and automatically adjust the injection operation to ensure the accuracy and consistency of liquid injection. Through closed-loop control, they optimize the injection process and reduce deviations caused by external changes or system errors. Common feedback control methods include PID (Proportional-Integral-Derivative Control), which precisely controls the system response by adjusting control parameters. Of course, other feedback control methods can also be used.

[0222] The control device is used to receive target formula information and, based on the target formula information, to determine the type and dosage of the target liquid;

[0223] In this embodiment, the target formula information refers to the electrolyte formula. The target formula information is usually entered by the user through the user interface. Of course, it can also be entered through other means, such as mobile terminals such as mobile phones and tablets, or by scanning and identifying information cards made of NFC (Near Field Communication). No specific restrictions are made here.

[0224] The control device is used to receive the identification information and location information of the injection bottle 15 at the liquid extraction location 10d. The control device is used to determine the target injection bottle 15 based on the type of target liquid, the identification information and location information of the injection bottle 15.

[0225] During the liquid injection process, at the feeding stage, the corresponding injection bottle 15 is assigned based on the target formula information. The identification information of the injection bottle 15 refers to the unique information used to identify each injection bottle 15, usually recorded through barcodes, QR codes, RFID (Radio Frequency Identification) tags, or other forms of identifiers. This identification information contains detailed information about the injection bottle 15, such as the type of liquid, concentration, batch number, etc., and is data for liquid injection and tracking the source of the liquid. In some embodiments, the injection bottle 15 serves as an intermediate carrier bottle, meaning that the injection bottle 15 is reused. When the injection bottle 15 is returned to the feeding station after use, its identification information may still be recorded as a barcode, QR code, RFID tag, or other form of identifier. The detailed information of the liquid in the injection bottle 15 (such as the type of liquid, concentration, batch number, etc.) is managed through a database, and this data is recorded over time.

[0226] In this embodiment, the position information of the injection bottle 15 mainly refers to the position information of the injection bottle 15 on the first tray assembly 20; in the entire injection system 1, the position information of the injection bottle 15 refers to the position of the injection bottle 15 in the operating space.

[0227] For example, as shown in Figure 9, the first tray assembly 20 has a position code of 16 in the lower right corner (6th in the first row). Assuming that 100ml of DMC (Dimethyl Carbonate) solvent is placed at this position, the position information of the injection bottle 15 is: liquid extraction position 16, and the identity information of the injection bottle 15 is: 100ml DMC.

[0228] The identity information and location information of the injection bottle 15 can be entered by the user through the user interface, scanned by scanning devices such as industrial mobile phones, or identified by scanning an information card made of NFC. No specific restrictions are made here.

[0229] The control device is used to receive the location information and identity information of the reagent bottle 16. The control device is used to determine the target reagent bottle 16 based on the type of target liquid, the location information and identity information of the reagent bottle 16.

[0230] The location information of reagent bottle 16 refers to the specific location of reagent bottle 16 in the operating space. It is usually obtained through sensors, cameras, vision systems or location information markers. The control device uses this location information to find and locate each dispensing bottle 15, thereby realizing the liquid transfer operation. Referring to the above-mentioned identification information of dispensing bottle 15, it will not be explained in detail here.

[0231] The control device is used to receive the identity information of the configuration bottle 17 at the liquid injection station, and the control device is used to associate the identity information of the configuration bottle 17 with the target formula information and confirm it as the target configuration bottle 17.

[0232] The bottle 17 identity information can be configured in the following ways: it can be entered by the user through the user interface, scanned by scanning devices such as industrial mobile phones, or identified by scanning an information card made of NFC. No specific restrictions are made here.

[0233] The control device is used to complete the injection according to the type of target liquid. The injection process for at least one type is as follows: the control device is used to determine the first target injection volume and the first injection speed of the first injection device 11 according to the properties and dosage of the target liquid, and to determine the second target injection volume and the second injection speed of the second injection device 12; the control device is used to control the first injection device 11 to draw liquid from the target injection bottle 15 according to the first target injection volume and inject the liquid into the target preparation bottle 17 according to the first injection speed, and to control the second injection device 12 to draw liquid from the target reagent bottle 16 according to the second target injection volume and inject the liquid into the target preparation bottle 17 according to the second injection speed.

[0234] The working principle and process of the control device are illustrated below:

[0235] First, the control device identifies the properties and required injection conditions of the target liquid based on its type. The properties of the target liquid (such as viscosity, flowability, density, etc.) affect the accuracy and speed of the injection process. For different types of liquids, the control device will assess their specific requirements and determine the appropriate injection equipment and its corresponding parameters.

[0236] The control device determines two parameters of the injection process based on the properties of the target liquid (such as viscosity, bubble generation, etc.) and the required dosage:

[0237] The target injection volume and injection rate of the first injection device 11 are as follows:

[0238] Based on the type of target liquid and the preset dosage, the system calculates the target injection volume (i.e., the volume of liquid to be extracted from the target injection bottle 15) and the first injection speed (i.e., the injection speed of the liquid from the target injection bottle 15 to the target preparation bottle 17) of the first injection device 11. The control device sets these parameters according to the fluidity of the liquid and the capacity of the first injection device 11. For example, if the target liquid is viscous, the injection speed may need to be slowed down to reduce equipment blockage or liquid splashing. These adjustments can be made by the user through the user interface or by pre-entering relevant rules, such as dividing the viscosity into segments and using different injection speeds for each segment.

[0239] The target injection volume and injection rate of the second injection device 12 are as follows:

[0240] The control device also needs to determine the injection volume and injection speed of the second injection device 12 based on the liquid type of the target reagent bottle 16 and the requirements of the target preparation bottle 17. Furthermore, if the second liquid differs significantly from the first liquid in properties (such as viscosity or reactivity), the control device may need to adjust the injection parameters of the second device to improve the stability and accuracy of the injection process.

[0241] Actual injection process:

[0242] Operation of the first injection device 11:

[0243] Based on the determined first target injection volume and first injection rate, the control device controls the first injection device 11 (such as a pipette pump, pipette head 720, etc.) to perform the following operations:

[0244] Liquid extraction: The first liquid injection device 11 first extracts the required liquid from the target liquid injection bottle 15 according to the identity information and location information of the target liquid injection bottle 15.

[0245] Liquid injection: The device then injects liquid into the target configuration bottle 17 at a set first injection rate to prevent over- or under-injection during the injection process.

[0246] Operation of the second injection device 12:

[0247] Similarly, the control device operates the second injection device 12 (such as another pipette pump or titration device) to perform the following actions based on the second target injection volume and the second injection rate:

[0248] Draw liquid: Draw liquid from target reagent bottle 16.

[0249] Injecting the liquid: Inject the liquid into the target preparation bottle 17 at the set second injection rate. This process may involve adjusting the type and properties of the liquid, especially when there are significant differences in reactivity or physical properties between different liquids.

[0250] In addition, the control device not only needs to precisely control the operation of each device, but also needs to achieve coordination and synchronization between multiple injection devices, such as synchronous control, real-time feedback and adjustment, injection volume verification, and injection completion confirmation.

[0251] Synchronous control is necessary if the liquid injection process involves two liquids (such as different additives or solvents). The control device may need to adjust the operating timing of the two injection devices based on reaction or physical characteristics. Synchronous control ensures that the appropriate liquid is injected into the target preparation bottle 17 at the correct time. For example, during liquid mixing or reaction, the control device may need to inject the first and second liquids into the preparation bottle 17 simultaneously or in a specific ratio within a specific timeframe.

[0252] Real-time feedback and adjustment: The control device monitors the liquid transfer process in real time through sensors or real-time monitoring systems (such as flow meters, pressure sensors, temperature sensors, etc.). If the injection volume or injection rate is found to be inconsistent with the target, the system will automatically adjust the parameters or issue an alarm signal.

[0253] After the target liquid is injected, the control device can verify and record the injection process, and then check and confirm the process.

[0254] Liquid volume verification uses feedback sensors to verify whether the liquid volume in the target injection bottle 15 and the target preparation bottle 17 meets expectations. If a liquid volume deviation is detected, the system may initiate a replenishment operation.

[0255] Once the injection is complete, the system can be set up with an automatic check mechanism to confirm that all liquids have been injected and provide a status report to the operator through the user interface.

[0256] Control devices are typically equipped with advanced user interfaces (such as touch screens, computer interfaces, etc.). Operators can input parameters such as the type of target liquid, the required dosage, and the injection rate through this interface, and monitor the entire injection process in real time. The injection system can also provide detailed operation logs and abnormal alarms, making the injection process transparent and traceable.

[0257] In this embodiment, the control device adjusts the target injection volume and injection speed of multiple injection devices according to the type, performance and dosage requirements of the target liquid. Each injection device performs the injection task at a preset time and at a suitable speed. The system's real-time monitoring, feedback adjustment and device coordination functions enable it to complete the liquid transfer task with high precision. Thus, this embodiment can quickly complete the sampling and injection of electrolyte.

[0258] In some embodiments, the workbench 10 is provided with a first preset position 10c, a liquid extraction position 10d, a first liquid injection position 10a, a second liquid injection position 10b and a first storage area 10e, and the liquid injection system 1 includes a control device.

[0259] The control device is communicatively connected to the first moving device 200 and is used to control the first moving device 200 to move the injection bottle 15 from the first preset position 10c to the liquid extraction position 10d.

[0260] The control device is connected to the liquid extraction device 100 for controlling the liquid extraction device 100 to extract the liquid from the injection bottle 15 at the liquid extraction position 10d according to the target injection volume, and inject it into the configuration bottle 17 at the first injection position 10a.

[0261] The control device is communicatively connected to the second moving device 500 and is used to control the second moving device 500 to move between the first storage area 10e and the second injection position 10b, so as to drive the clamping device 600 and the pipetting device 700 to move between the first storage area 10e and the second injection position 10b.

[0262] The control device is communicatively connected to the clamping device 600 and is used to control the clamping device 600 to clamp or release the reagent bottle 16.

[0263] The control device is communicatively connected to the pipetting device 700 and is used to control the pipetting device 700 to draw liquid from the reagent bottle 16 in the first storage area 10e and inject the drawn liquid into the preparation bottle 17 in the second dispensing position 10b.

[0264] The control device is communicatively connected to the weighing device 13 and is used to control the weighing device 13 to move and switch between the first liquid injection position 10a and the second liquid injection position 10b.

[0265] The control device is also used to receive the weight signal returned by the weighing device 13. After the liquid is injected, the control device is used to determine whether the liquid preparation in the preparation bottle 17 is qualified based on the weight signal.

[0266] In this embodiment, the operation of each device in the injection system 1 is coordinated by the control device to realize automated liquid extraction, injection and quality monitoring, thereby improving the injection efficiency of the injection system 1.

[0267] In some embodiments, during the injection phase, the control device controls the weighing device 13 to be in the first injection position 10a, controls the pumping device 100 to extract liquid from the first target injection bottle 15 in the pumping position 10d according to the target injection volume, and injects it into the preparation bottle 17 in the first injection position 10a; controls the weighing device 13 to move from the first injection position 10a to the second injection position 10b; controls the second moving device 500 to move the pipetting device 700 to the second storage area 10f, and controls the pipetting head 720 of the pipetting device 700 to align with the suction tip 18 in the second storage area 10f. The installation process is as follows: control the second moving device 500 to move the pipetting device 700 to the first storage area 10e, control the pipetting device 700 to draw liquid from the first target reagent bottle 16 according to the target dispensing volume, control the second moving device 500 to move the pipetting device 700 to the second dispensing position 10b, control the moving device to release liquid into the preparation bottle 17; control the second moving device 500 to move the pipetting device 700 to the third storage area 10h, control the pipetting head 720 of the pipetting device 700 to disengage from the pipette tip 18 so that the pipette tip 18 can be returned to the third storage area 10h.

[0268] During the injection process, the control device communicates with various devices (such as the weighing device 13, the pumping device 100, the pipetting device 700, and the second moving device 500) to ensure that each device operates according to a predetermined time, sequence, and precision. The control device monitors the target volume of pumping and injection, ensuring that each step achieves the set injection volume requirement as much as possible. This control can be achieved through real-time feedback signals (such as the weighing device 13 and sensors). After each injection, the pipetting head 720 is detached and the suction tip 18 is retrieved, thereby reducing contamination and cross-contamination.

[0269] In this embodiment, the liquid volume in each injection step is controlled by the linkage between the control device and various devices (such as the weighing device 13, the liquid extraction device 100, the liquid transfer device 700, the second moving device 500, etc.). The whole process is almost fully automated. The injection system can complete the extraction, injection, movement and recovery of liquid with reduced manual intervention, thereby improving the efficiency of electrolyte preparation.

[0270] In some embodiments, during the feeding stage, the control device controls the first moving device 200 to move the injection bottle 15 from the first preset position 10c to the extraction position 10d; the control device also controls the second moving device 500 to move the clamping device 600 to move the target reagent bottle 16 from the first storage area 10e to the weighing device 13 at the second injection position 10b, controls the weighing device 13 to move the target reagent bottle 16 from the second injection position 10b to the first injection position 10a, controls the extraction device 100 to inject liquid into the target reagent bottle 16, controls the weighing device 13 to reset the target reagent bottle 16 to the first injection position 10a, and controls the second moving device 500 and the clamping device 600 to reset the target reagent bottle 16 to the first storage area 10e.

[0271] In this embodiment, the material bottle of the second injection device 12 is fed by the first injection device 11, so that the first injection and the second injection use the same batch of raw material solution, reducing the performance difference of the electrolyte caused by the inconsistency of the raw material solution, and facilitating the improvement of the consistency of electrolyte sample preparation.

[0272] In some embodiments, the second liquid injection device 12 includes a detection device 800, which is disposed on a second moving device 500. The second moving device 500 is used to move the detection device 800 to a first storage area 10e to detect the storage amount of reagent bottles 16 in the area and output a reagent bottle 16 storage amount detection signal. The second moving device 500 is also used to move the detection device 800 to the liquid injection station to detect the storage amount of the preparation bottle 17 at the liquid injection station and output a corresponding preparation bottle 17 storage amount detection signal.

[0273] The detection device 800 refers to a device used to detect items, components, or states, and typically includes sensors, detection modules, cameras, etc. In this embodiment, through the detection device 800, the second liquid injection device 12 can monitor the bottle inventory in the first storage area 10e and the liquid injection station in real time, reducing the interruption of operation due to insufficient bottles. The inventory information is detected in real time and fed back to the control device, which can make timely adjustments based on this information.

[0274] In this embodiment, the detection device 800 is used to monitor and provide feedback on the bottle inventory information in different storage areas and injection stations in real time, thereby enhancing the automation and intelligence of the injection system 1.

[0275] In some embodiments, the liquid injection system 1 includes a barcode scanning device 900, which is disposed on a second moving device 500. The second moving device 500 is used to move the barcode scanning device 900 to a first storage area 10e to scan and identify the identity and location identifiers of reagent bottles 16 in that area, and output the corresponding identity signal and location information of the reagent bottle 16. The second moving device 500 is also used to move the barcode scanning device 900 to a second liquid injection position 10b to scan the identity identifiers of the configuration bottles 17 at that position, and output the corresponding identity information of the configuration bottles 17.

[0276] The scanning device 900 is a device that performs the scanning function and is typically used to scan identification information such as barcodes or QR codes, for example, barcode / QR code scanning, RFID technology, or location information identification. Barcode / QR code scanning refers to the scanning device 900 using a high-efficiency scanner (such as a barcode scanner or QR code reader) to read the information of the reagent bottle 16 and the preparation bottle 17.

[0277] This embodiment enhances the accuracy and transparency of material management by adding a barcode scanning device 900. Through scanning and feedback, the liquid injection system 1 can adjust the production process and improve production efficiency.

[0278] In some embodiments, please refer to Figures 14 to 16. The connecting bracket 540 includes a fourth connecting plate 544 and a connecting flange 545. The connecting flange 545 is disposed on the fourth connecting plate 544 and connected to the second connecting plate 542. The barcode scanning device 900 and the detection device 800 are disposed on the fourth connecting plate 544.

[0279] The connecting bracket 540 refers to a structural component used to support, fix or connect other components. In this solution, the connecting bracket 540 serves as an installation structure, providing a basis for installing the barcode scanner 900 and the detection device 800.

[0280] The fourth connecting plate 544 is part of the connecting bracket 540 and serves to support and connect other components. The fourth connection is typically a flat plate that provides mounting positions for the barcode scanner 900 and the detection device 800.

[0281] The connecting flange 545 refers to the structure that connects the fourth connecting plate 544 and the second connecting plate 542. The connecting flange 545 is typically integrally formed with the fourth connecting plate 544; for example, the fourth connecting plate 544 and the connecting flange 545 are formed by bending the same piece of sheet metal. The connecting flange 545 helps provide additional support and stability, making the connection more robust. The second connecting plate 542, as mentioned above, is the connecting plate used to mount the clamping device 600. The connecting flange 545 is mounted on the second connecting plate 542, which serves as a component of the support structure.

[0282] In this embodiment, the scanning device 900 and the detection device 800 are fixed on the fourth connecting plate 544 and connected to the second connecting plate 542 via the connecting flange 545. This integrates the scanning device 900 and the detection device 800 onto the fourth connecting plate 544, improving the space utilization of the equipment and optimizing the system layout. In addition, the design of the fourth connecting plate 544 connecting to the second connecting plate 542 via the connecting flange 545 simplifies the installation and assembly process of the bracket. The flange connection method may be more convenient than the traditional bolt or welding method, reducing assembly time and cost.

[0283] In some embodiments, please continue to refer to Figures 14 to 16. The thickness direction of the fourth connecting plate 544 extends horizontally. The fourth connecting plate 544 has a first side and a second side opposite to each other along its thickness. The barcode scanning device 900 is disposed on the first side of the fourth connecting plate 544, and the detection device 800 is disposed on the second side of the fourth connecting plate 544.

[0284] The fourth connecting plate 544, mentioned in the previous embodiment, is a connecting structure. In this embodiment, the fourth connecting plate 544 extends horizontally in its thickness direction and has opposing first and second sides. "Thickness direction" refers to the direction perpendicular to the main plane of the fourth connecting plate 544, while "horizontal direction" is the direction parallel to the plane. That is to say, the main plane of the fourth connecting plate 544 is placed vertically.

[0285] In this embodiment, by arranging the barcode scanning device 900 and the detection device 800 on both sides of the fourth connecting plate 544, space can be utilized to the maximum extent and interference between the two devices can be reduced. The separation of the barcode scanning device 900 and the detection device 800 allows them to perform their functions independently. At the same time, since they are installed on the same connecting plate, the compactness and coordination of the liquid injection system 1 are improved.

[0286] In some embodiments, please continue to refer to Figures 14 to 16. The fourth connecting plate 544 is provided with a first arc-shaped groove 544a and a second arc-shaped groove 544b located on a circumference. The scanning device 900 is provided with a third connector and a fourth connector. The third connector is connected to the first arc-shaped groove 544a and can move along the first arc-shaped groove 544a. The fourth connector is connected to the second arc-shaped groove 544b and can move along the second arc-shaped groove 544b, so that the scanning device 900 can rotate around the center of the circumference.

[0287] The first arc-shaped groove 544a and the second arc-shaped groove 544b can be understood as arc-shaped tracks located on the fourth connecting plate 544, providing channels for the connecting parts of the scanning device 900 to move along the arc-shaped trajectory; the first arc-shaped groove 544a and the second arc-shaped groove 544b provide the mechanical path required for the scanning device 900 to rotate around the circumference. By setting two arc-shaped grooves, the scanning device 900 can complete the rotation action around a certain point (i.e., the center of the circle) under the action of these two grooves, thereby realizing scanning operations at different angles.

[0288] The third connector and the fourth connector are connected to the first arc-shaped groove 544a and the fourth connector is connected to the second arc-shaped groove 544b. These two connectors are the connecting links between the barcode scanning device 900 and the fourth connecting plate 544. They can move freely along the arc-shaped trajectory in their respective arc-shaped grooves, so that the barcode scanning device 900 can rotate around the center. For example, the third connector and the fourth connector are threaded connectors.

[0289] In this embodiment, by setting two arc-shaped grooves and a connector that can move along the grooves, the barcode scanning device 900 can rotate within a certain range on the circumference, thereby covering more scanning angles and a wider range, improving the flexibility and efficiency of the barcode scanning device 900; the design of the arc-shaped grooves enables the barcode scanning device 900 to complete a wide range of scanning tasks in a limited space, solving the problem that traditional multi-angle scanning devices need to occupy a lot of space.

[0290] In some embodiments, please continue to refer to Figures 14 to 16. The fourth connecting plate 544 is further provided with a third arcuate groove 544c and a fourth arcuate groove 544d located on another circumference. The detection device 800 is provided with a fifth connector and a sixth connector. The fifth connector is connected to the third arcuate groove 544c and can move along the third arcuate groove 544c. The sixth connector is connected to the fourth arcuate groove 544d and can move along the fourth arcuate groove 544d, so that the detection device 800 can rotate around the center of the circumference.

[0291] The third arc-shaped groove 544c and the fourth arc-shaped groove 544d are the same as the first arc-shaped groove 544a and the second arc-shaped groove 544b in the previous embodiment; for related explanations, please refer to the previous embodiment. The fifth connector and the sixth connector are the same as the third connector and the fourth connector in the previous embodiment; for related explanations, please refer to the previous embodiment.

[0292] In this embodiment, by setting two arc-shaped grooves and a connecting member that can move along the grooves, the detection device 800 can rotate within a certain range on the circumference, thereby covering more detection angles and a wider range, improving the flexibility and efficiency of the detection device 800; the design of the arc-shaped grooves enables the detection device 800 to complete a wide range of detection tasks in a limited space, solving the problem that traditional multi-angle detection devices 800 need to occupy a lot of space.

[0293] In some embodiments, please refer to Figures 10 and 11, the injection system 1 includes a second tray assembly 19, and a first storage area 10e, a second storage area 10f and a third storage area 10h are disposed on the second tray assembly 19.

[0294] The second tray assembly 19 is a supporting structure in the liquid injection system 1, used to place and separate different functional areas. The main function of the second tray assembly 19 is to provide stable support and layout for different materials or equipment during the liquid injection process. For example, the second tray assembly 19 may be a fixed or movable component, and its position or angle can be adjusted according to operational requirements. For example, the second tray assembly 19 can be placed on the workbench 10 or on the conveying device 14.

[0295] The first storage area 10e, located on the second tray assembly 19, is a separate area. In this embodiment, the first storage area 10e is used to store reagent bottles 16. The second storage area 10f, also located on the second tray assembly 19, is another separate area used to store unused pipette tips 18. The third storage area 10h, also located on the second tray assembly 19, is a specially designed area that may be used to store items that have been filled with liquid or waste, such as used pipette tips 18.

[0296] In this embodiment, by setting a first storage area 10e, a second storage area 10f, and a third storage area 10h on the second tray assembly 19, the second tray assembly 19 is used to circulate within the conveying device 14, and the liquid injection system 1 can realize the orderly storage, rapid retrieval, and waste management of materials.

[0297] This application also proposes a control method applied to the injection system 1 of any of the foregoing embodiments, the control method comprising:

[0298] Upon receiving the injection command, the first injection device 11 is controlled to inject the target liquid into the target preparation bottle 17 once according to the first target injection volume and the first target injection speed;

[0299] When the injection volume of a single injection reaches the first target injection volume, the first injection device 11 is controlled to stop injection, and the second injection device 12 is controlled to perform a second injection of the target liquid into the target preparation bottle 17 according to the second target injection volume and the second target injection speed, until the preparation bottle 17 reaches the target injection volume of the target liquid.

[0300] Upon receiving the injection command, the injection system 1 needs to prepare several things, such as feeding the first injection device 11 and the second injection device 12, feeding the dispensing bottle, and after feeding, it also needs to:

[0301] Obtain target formulation information, and determine the type and dosage of target liquid based on the target formulation information;

[0302] Obtain the identity information and location information of injection bottle 15 at the liquid extraction location 10d, and determine the target injection bottle 15 based on the type of target liquid, the identity information and location information of injection bottle 15.

[0304] Obtain the identity information of the configuration bottle 17 at the injection station, associate the identity information of the configuration bottle 17 with the target formula information, and confirm it as the target configuration bottle 17.

[0305] Furthermore, after determining the type and dosage of the target liquid based on the target formulation information, and before controlling the first injection device 11 to inject the target liquid into the target preparation bottle 17 in one injection step according to the first target injection volume and the first target injection speed, it is usually necessary to obtain the viscosity of the target liquid, determine the first target injection volume and the first injection speed based on the viscosity and dosage of the target liquid, and determine the second target injection volume and the second injection speed.

[0306] Generally, the liquid injection system 1 includes a workbench 10, which has a first storage area 10e and a placement area for the preparation bottle 17. The second liquid injection device 12 includes a second moving device 500 and a pipetting device 700.

[0307] After the second moving device 500 drives the pipetting device 700 to move to the first storage area 10e, the pipetting device is controlled to draw liquid from the target reagent bottle 16 according to the second target dispensing volume.

[0308] The second moving device 500 is controlled to move the pipetting device 700 from the first storage area 10e to the second injection position, and the pipetting device 700 is controlled to inject the liquid into the target preparation bottle 17 at the second target injection speed.

[0309] In this embodiment, by setting the injection speed of the first injection to be greater than that of the second injection, the injection speed of the injection system 1 is increased by the high speed of the first injection device 11, thus achieving high-throughput injection. The injection accuracy of the injection system 1 is controlled by the high precision of the second injection device 12, thus achieving high-precision injection. In this way, by performing injection in two stages, high-throughput and high-precision injection are achieved, thereby improving injection efficiency.
