When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0022] Please see Figures 1 to 9 In one embodiment of the present invention, the laboratory solution preparation apparatus 100 includes: Receiving component 1 is used for mixing multiple sample reagents; Liquid dispensing device 2, which is located on one side of the receiving component 1, is used to add a preset amount of sample reagent into the receiving component 1; A flow control device 3 is disposed between the liquid dispensing device 2 and the receiving component 1 to control the flow rate of sample reagents entering the receiving component 1; A magnetic stirring device 4, wherein the receiving component 1 is placed in the magnetic stirring device 4 to stir and mix various sample reagents within the receiving component 1; and Transfer device 5, which is driven and connected to the magnetic stirring device 4, to drive the receiving part 1 to move closer to or away from the liquid distribution device 2; A gripping device 6 is disposed on one side of the transfer device 5 and is used to grip one side of the liquid dispensing device 2 and insert it into the receiving component 1 to deliver the sample reagent into the receiving component 1.

[0023] In this embodiment, the laboratory solution preparation equipment 100 includes a receiving component 1, a liquid dispensing device 2, a flow control device 3, a magnetic stirring device 4, a transfer device 5, and a gripping device 6. The liquid dispensing device 2 adds a preset amount of sample reagent to the receiving component 1, thereby achieving precise control over the quality of the sample reagent and ensuring the chemical stability of the prepared solution. The flow control device 3 controls the flow rate of the sample reagent into the receiving component 1, effectively controlling the liquid addition flow rate and velocity, reducing manual intervention in the mixing process of at least two liquids, preventing harm to laboratory personnel from violent reactions caused by the addition of corrosive solutions, and avoiding safety accidents. The magnetic stirring device 4 thoroughly stirs and mixes the mixture in the receiving component 1. The transfer device 5 drives the receiving component 1 closer to or further away from the liquid dispensing device 2, thereby achieving an automated solution preparation process. The gripping device 6 inserts the liquid dispensing device 2 into the receiving component 1, further reducing manual operation.

[0024] Specifically, the receiving component 1 is placed on the magnetic stirring device 4. It should be noted that the magnetic stirring device 4 is prior art, and will not be described in detail here. The magnetic stirring device 4 is installed on the transfer device 5. That is, under the drive of the transfer device 5, the magnetic stirring device 4 and the receiving component 1 can be moved closer to or away from the liquid distribution device 2. When they are close, the gripping device 6 grips one side of the liquid distribution device 2 and inserts it into the receiving component 1 so that the sample reagents flowing out of the liquid distribution device 2 can smoothly enter the receiving component 1. The flow rate of the sample reagents entering the receiving component 1 is controlled by the flow control device 3. After the sample reagents have completely entered the receiving component 1, the gripping device 6 grips and removes the liquid distribution device 2 from the receiving component 1. Then, under the drive of the transfer device 5, the receiving component 1 moves away from the liquid distribution device 2 so that the staff can obtain the mixed receiving component 1. It should be noted that the gripping device 6 can be a robotic arm. In this way, the receiving part 1 can be placed on the magnetic stirring device 4 or taken away from the magnetic stirring device 4 by the gripping device 6.

[0025] It should be noted that the receiving part 1 can be a bottle body. That is, by adding a preset amount of sample material and sample reagent into the bottle body, and transferring it to the magnetic stirring device 4 through the gripping device 6, the mixture in the bottle body is stirred and the solution preparation process is completed. It is understood that the bottle body needs to have good chemical stability, such as corrosion resistance and solvent resistance; and good physical properties, such as mechanical strength, heat resistance and transparency. For example, the bottle body can be a glass bottle, a polytetrafluoroethylene (PTFE) bottle, a polyethylene (PE) bottle, etc.

[0026] It should be further noted that, in order to ensure the accuracy and stability of the experiment, the laboratory solution preparation equipment 100 also includes a chamber, which is an oxygen-free environment. The receiving device 1, liquid dispensing device 2, flow control device 3, magnetic stirring device 4, transfer device 5, and gripping device 6 are all housed in the chamber. The chamber can be filled with an inert gas (such as nitrogen), thereby creating an oxygen-free environment inside, which can effectively prevent oxidation reactions, ensure the chemical stability of the solution, and ensure the accuracy of the experimental results.

[0027] In one implementation, please refer to Figure 1 and Figure 2 The receiving component 1 is provided in multiple ways, and the multiple receiving components 1 are placed at intervals in the magnetic stirring device 4; Multiple liquid dispensing devices 2 are provided, each liquid dispensing device 2 is used to store each sample reagent and to deliver at least one sample reagent to each receiving component 1. The flow control device 3 is provided in multiple ways, and each flow control device 3 is connected between each liquid distribution device 2 and each receiving part 1, so that multiple sample reagents can be mixed separately to meet experimental requirements.

[0028] In this embodiment, multiple receiving devices 1 are provided, and the multiple receiving devices 1 are placed at intervals on the magnetic stirring device 4. Multiple liquid dispensing devices 2 are also provided. Each liquid dispensing device 2 is used to store each sample reagent and can deliver at least one sample reagent to each receiving device 1. At the same time, multiple flow control devices 3 are also provided, and each flow control device 3 is connected between each liquid dispensing device 2 and each receiving device 1. In this way, the sample reagent entering each receiving device 1 can be precisely controlled, thereby enabling the preparation of multiple sample reagents at the same time and accelerating the solution preparation process.

[0029] In one implementation, please refer to Figure 2 Each of the liquid dispensing devices 2 includes: A storage bottle, wherein the storage bottle is used to store each sample reagent; and The pump assembly 22 is connected to the storage bottle and is used to draw sample reagents from the storage bottle; The first liquid adding component 23 is connected to the pumping assembly 22. The gripping device 6 is used to grip the side of the first liquid adding component 23 away from the pumping assembly 22 and insert it into the receiving component 1 to transport the sample reagent drawn into the pumping assembly 22 into the receiving component 1.

[0030] In this embodiment, each liquid dispensing device 2 includes a storage bottle, a pump assembly 22, and a first liquid adding component 23. The storage bottle is used to store sample reagents, while the pump assembly 22 is connected to the storage bottle to extract the corresponding sample reagents from the storage bottle. Meanwhile, one end of the first liquid adding component 23 is connected to the pump assembly 22, and the gripping device 6 grips the other end of the first liquid adding component 23 to insert the other end of the first liquid adding component 23 into the receiving component 1, so that the sample reagents extracted by the pump assembly 22 enter the receiving component 1 through the first liquid adding component 23. It should be noted that the storage bottle and the pump assembly 22 are prior art, and this application does not limit them in any way. The first liquid filling component 23 includes a first liquid filling head 231 and a first liquid filling pipe 232. The first liquid filling head 231 is connected to the pumping assembly 22, and the first liquid filling pipe 232 is connected to the side of the first liquid filling head 231 away from the pumping assembly 22. The gripping device 6 grips the first liquid filling pipe 232 and places it into the receiving component 1. It should be noted that the first liquid filling component 23 is also prior art, and this application does not limit it in any way.

[0031] Specifically, in order to ensure the weight of the sample reagent entering the receiving part 1, the laboratory solution preparation equipment 100 also includes a weighing component. The weighing component has a tray for placing the receiving part 1. The bottom of the tray is connected to a weighing sensor. First, the receiving part 1 is grasped and transferred to the weighing component by the gripping device 6. The weight of the receiving part 1 is weighed in real time by the weighing component, thereby achieving precise control of the quality of the sample reagent. It should be noted that the weighing component is prior art, and this application does not limit it in any way.

[0032] Please also see Figure 8 and Figure 9To prevent residual sample reagents in the first liquid addition tube 232 from dripping when the receiving component 1 is moved, the laboratory solution preparation equipment 100 also includes a clamping assembly 8. The clamping assembly 8 includes a connecting frame 81, a second driving component 82, a first clamping component 83, and a second clamping component 84. The second driving component 82 is installed on one side of the connecting frame 81, and the second clamping component 84 is located on the other side of the connecting frame. The second driving component 82 is driven to connect to the first clamping component 83, thereby driving the first clamping component 83 to move towards the second clamping component 84. The first liquid addition tube 232 is located between the first clamping component 83 and the second clamping component 84. As the first clamping component 83 is driven by the second driving component 82, it can press the first liquid addition tube 232 against the second clamping component 84, thereby locking the first liquid addition tube 232 so that the residual sample reagents in the first liquid addition tube 232 cannot drip, thus avoiding corrosive solutions from damaging the experimental equipment and ensuring the service life of the experimental equipment.

[0033] For further details, please refer to Figure 8 and Figure 9 The second driving component 82 includes a second driving motor 821, a threaded rod 822, two slides 823, and four connecting rods 824. The second driving motor 821 is mounted on the connecting frame 81 and is driven by the threaded rod 822. The two slides 823 are spaced apart on the threaded rod 822 and are threadedly connected to the threaded rod 822. Each slide 823 is connected to two connecting rods 824. Each connecting rod 824 is connected to the side of the first clamping member 83 away from the second clamping member 84 on the side away from the slide 823. Thus, under the drive of the second driving motor 821 and other components, the first clamping member 83 can move stably toward the second clamping member 84 and can stably squeeze the first liquid filling tube 232. It should be noted that the first liquid filling tube 232 is a flexible tube.

[0034] For further details, please refer to Figure 8 and Figure 9 The first clamping member 83 has a first extrusion strip 831 on the side facing the second clamping member 84. The outer surface of the first extrusion strip 831 is arc-shaped. There are multiple second clamping members 84, which are spaced apart on the connecting frame 81. Each second clamping member 84 has an extrusion groove 841. The bottom wall of the extrusion groove 841 has a protrusion 842, and the side wall of the extrusion groove 841 has an installation groove 843. In this way, under the drive of the second drive motor 821, the first extrusion strip 831 enters the installation groove 843. With the cooperation of the first extrusion strip 831 and the protrusion 842, the first liquid addition tube 232 can be clamped and locked, so that the sample reagent remaining in the first liquid addition tube 232 cannot drip out, avoiding corrosive solution from damaging the experimental equipment and ensuring the service life of the experimental equipment.

[0035] Please also see Figure 8 and Figure 9 The first clamping member 83 may also be provided with a plurality of spaced-apart squeezing blocks 832 on the side facing the second clamping member 84. The squeezing blocks 832 are adapted to the squeezing groove 841, so as to squeeze the first liquid adding tube 232 to limit the sample reagent from dripping from the first liquid adding tube 232.

[0036] The laboratory solution preparation device 100 also includes two tension springs 85. One side of each tension spring 85 is connected to the first clamping member 83, and the other side of each tension spring 85 is connected to the connecting frame 81. This ensures that the first clamping member 83 and the second clamping member 84 can stably squeeze the first liquid addition tube 232.

[0037] In one implementation, please refer to Figures 3 to 6 Each of the flow control devices 3 includes a mounting housing 31, a flow control component 32, and a connecting pipe 33. One side of the connecting pipe 33 is connected to the liquid storage bottle, and the side of the connecting pipe 33 near the liquid storage bottle is connected to the first liquid dispensing head 231. The other side of the connecting pipe 33 near the liquid storage bottle is installed on the outer wall of the mounting housing. The flow control component 32 is installed inside the mounting housing and is telescopically connected to the connecting pipe 33 so that the connecting pipe 33 can connect to or block the liquid storage bottle, thereby effectively controlling the liquid dispensing flow rate and velocity, reducing manual intervention in the mixing process of at least two liquids, preventing harm to laboratory personnel caused by violent reactions due to the addition of corrosive solutions, and avoiding safety accidents.

[0038] In this embodiment, each flow control device 3 includes a mounting housing 31, a flow control component 32, and a connecting pipe 33. One side of the connecting pipe 33 is connected to the storage bottle, and the connecting pipe 33 is connected to the first liquid dispensing head 231 on the side near the storage bottle. The connecting pipe 33 is mounted on the outer wall of the mounting housing 31 on the other side near the storage bottle. The flow control component 32 is installed inside the mounting housing and is telescopically connected to the connecting pipe 33 so that the connecting pipe 33 and the storage bottle can be connected or blocked, thereby realizing the flow rate and velocity of the sample reagent entering the first liquid dispensing head 231.

[0039] In one implementation, please refer to Figures 3 to 6 The connecting pipe 33 includes a first pipe 331, a second pipe 332, and a third pipe 333 that are spaced apart and connected to each other.

The first pipe 331 is connected to the liquid storage bottle. The second pipe 332 is connected to the flow control component 32. The third pipe 333 is connected to the first liquid filling head 231. The flow control component 32 includes a first drive member 321 and a blocking member 322. The first drive member 321 is installed in the mounting housing and is driven to connect to the blocking member 322 so as to drive the blocking member 322 to extend out of the mounting housing and move within the second pipeline 332 to close or open the first pipeline 331 and the third pipeline 333.

[0040] In this embodiment, the connecting pipe 33 includes a first pipe 331, a second pipe 332, and a third pipe 333 that are spaced apart and connected to each other. The second pipe 332 and the third pipe 333 are arranged opposite to each other. The first pipe 331 is located between the second pipe 332 and the third pipe 333. The first pipe 331 is connected to a storage bottle, the second pipe 332 is connected to a flow control component 32, and the third pipe 333 is connected to a first filling head 231. That is, the flow control component 32 can block or open the connection between the first pipe 331 and the third pipe 333. It should be noted that the connecting pipe 33 is T-shaped.

[0041] Specifically, the flow control component 32 includes a first driving member 321 and a blocking member 322. The first driving member 321 is installed inside the mounting housing and is driven to extend the blocking member 322 outside the mounting housing. The blocking member 322 moves within the second pipeline 332 to block the first pipeline 331, preventing the sample reagent from entering the third pipeline 333 through the first pipeline 331. Conversely, the blocking member 322 opens the second pipeline 332, allowing the sample reagent to enter the third pipeline 333 through the first pipeline 331 and then into the receiving member 1. It should be noted that a through hole is provided inside the mounting housing for the blocking member 322 to pass through.

[0042] In one implementation, please refer to Figures 3 to 6 The flow control assembly 32 includes an installation sleeve 323 and a first transmission member 324. The installation sleeve 323 forms a cavity 3231 with openings at both ends. The first driving member 321 is driven to the first transmission member 324 so that the first transmission member 324 moves within the cavity 3231. One side of the first transmission member 324 is driven to the sealing member 322 so that the sealing member 322 seals the first pipeline 331.

[0043] In this embodiment, the flow control component 32 includes a mounting sleeve 323 and a first transmission member 324. A cavity 3231 with openings at both ends is formed in the mounting sleeve 323. The first driving member 321 is driven to be connected to the first transmission member 324 so that the first transmission member 324 moves back and forth in the cavity 3231. The first transmission member 324 is driven to be connected to the sealing member 322 on the side away from the first driving member 321 so that the sealing member 322 moves back and forth with the first transmission member 324 to block or open the first pipeline 331.

[0044] Specifically, the first driving component 321 is a drive motor, and the first transmission component 324 includes a first driving gear 3241 and a rack 3242. The first driving gear 3241 is connected to the output shaft of the drive motor and meshes with the rack 3242. The rack 3242 is connected to the sealing component 322. It should be noted that the rack 3242 can be cylindrical or cuboid, or other shapes. In this embodiment, the rack 3242 is cylindrical.

[0045] Furthermore, to ensure the stability of the rack 3242's movement within the mounting housing, the flow control assembly 32 also includes a fixing seat 325. The fixing seat 325 is installed within the mounting housing, and a limiting groove 3251 is formed on the side of the fixing seat 325 facing the rack 3242. The rack 3242 is movably connected within the limiting groove 3251, and the limiting groove 3251 is U-shaped. That is, under the restriction of the limiting groove 3251, the rack 3242 can move stably within the mounting housing, effectively limiting the rack 3242 from shaking within the mounting housing.
