[0025] The following is combined Figures 1-3 This invention describes the reagent preparation station.

[0026] This utility model embodiment provides a reagent preparation station, such as... Figures 1 to 3 As shown, it includes an operating table 10, a robotic arm 20, a peristaltic pump 30, a dispensing pump 40, and a dissolving vessel 50. The robotic arm 20, peristaltic pump 30, and dispensing pump 40 are all mounted on the operating table 10. The operating table 10 has a beaker placement area and a dispensing bottle placement area 12. The beaker placement area is used to place beakers, and the dispensing bottle placement area 12 is used to place dispensing bottles. The robotic arm 20 can move beakers from the beaker placement area to the outlet of the peristaltic pump 30 to receive reagents, and can pour the liquid in the beakers into the dissolving vessel 50, repeatedly moving between the outlet of the peristaltic pump 30 and the dissolving vessel 50 to ensure that the reagent in the dissolving vessel 50 is prepared to the preset target. The dispensing pump 40 is used to dispense the liquid in the dissolving vessel 50 into the dispensing bottles transferred by the robotic arm 20 after the reagents have been dissolved in the dissolving vessel 50.

[0027] like Figure 1 and Figure 2As shown, the bottom of the operating table 10 is equipped with wheels, which can be omnidirectional wheels with locking function to adjust the position of the operating table 10 in the laboratory. A base is provided in the beaker placement area, and the base has at least one receiving slot, each slot capable of holding one beaker. The receiving slots on the base prevent the beakers from moving on the base. Optionally, the base is made of silicone or plastic, possessing a certain degree of flexibility to prevent damage from collisions between the beakers and the base. The beakers have a large capacity and can be used as weighing cups and preliminary dissolution cups for culture media or solvents to be diluted. After use, the beakers are temporarily stored in the beaker placement area until the robot moves them to the cleaning station for centralized cleaning, or they can be cleaned using the cleaning device in this station and then returned to the beaker placement area.

[0028] The aliquot bottles are Erlenmeyer flasks 200 and / or test tubes 100. Understandably, the aliquot bottle placement area 12 can hold only Erlenmeyer flasks 200, only test tubes 100, or both. To accommodate different reagent preparation needs, the aliquot bottle placement area 12 can hold both Erlenmeyer flasks 200 and test tubes 100. Specifically, a first frame and a second frame are installed in the aliquot bottle placement area 12. The first frame is a test tube rack, which can hold multiple test tubes 100. The second frame is a pad-shaped structure, fixed to the operating table 10 with bolts, and has multiple slots, each capable of holding one Erlenmeyer flask 200. The slots provide positioning for the Erlenmeyer flasks 200. Similarly, the second frame is a silicone or plastic plate, possessing a certain degree of flexibility to prevent damage from collisions with the Erlenmeyer flasks 200.

[0029] The reagent preparation station provided in this embodiment can be used for both preparing culture media and diluting common reagents. When preparing culture media, a robotic arm 20 moves a beaker, and the operator places the culture medium into the beaker. The robotic arm 20 then moves the beaker containing the culture medium to a peristaltic pump 30 to collect water as a diluent. The volume of the diluent is controlled by the peristaltic pump 30 and is less than the required amount for preparation. After collecting the diluent, the robotic arm 20 shakes the beaker to dissolve it, and then pours it into a dissolving pot 50. Afterward, the robotic arm 20 moves the empty beaker back to the peristaltic pump 30 to collect more diluent, using it for cleaning while continuing to provide diluent for the culture media preparation. The robotic arm 20 repeatedly moves the beaker between the dissolving pot 50 and the peristaltic pump 30 until the amount of diluent provided by the peristaltic pump 30 reaches the required amount for dissolving the culture medium. The dissolving pot 50 has a larger capacity than the beaker, facilitating the dissolving operation. After dissolution is complete, the robotic arm 20 transfers the dispensing bottle to the outlet of the dispensing pump 40 to receive the dissolved culture medium. At this time, the dispensing pump 40 controls the amount of culture medium received by the dispensing bottle to achieve the purpose of dispensing.

[0030] The process of diluting reagents is similar to that of preparing culture media. Specifically, there are multiple peristaltic pumps 30. The robotic arm 20 moves the beaker to the peristaltic pump 30 corresponding to the desired reagent to receive the diluted reagent, and then moves it to the peristaltic pump 30 corresponding to the diluent to receive the diluent, thus completing the initial preparation. The robotic arm 20 shakes the beaker to complete the initial dissolution, and then pours it into the dissolving pot 50, returning to the peristaltic pump 30 corresponding to the diluent to receive the diluent again. This process is repeated multiple times until the cumulative amount of diluent added reaches the preset amount. The reagent is diluted using the dissolving pot 50, and after mixing, it is dispensed into the dispensing bottles transferred by the robotic arm 20 using the dispensing pump 40.

[0031] The dispensing pump 40 is installed on the outlet pipe, one end of which is inserted into the dissolving vessel 50 from its open end. Alternatively, the outlet pipe can be integrated into the bottom of the dissolving vessel 50, so that after dissolution, the liquid is directly discharged from the bottom of the dissolving vessel 50 to the dispensing bottle via the outlet pipe.

[0032] The robotic arm 20 can perform multiple degrees of freedom of movement, such as lifting, horizontal movement, and flipping, allowing the actuator to move freely within the working area of ​​the operating table 10. The mechanical structure of the robotic arm 20 is prior art and will not be described in detail in this embodiment.

[0033] The reagent preparation station provided in this embodiment of the utility model has a robotic arm 20 that can hold beakers and dispensing bottles, enabling the movement of the beakers and dispensing bottles. A peristaltic pump 30 can add the reagent to be diluted and the diluent to the beaker. A dissolving pot 50 can receive the liquid poured into the beaker multiple times for the final dissolution or dilution operation. A dispensing pump 40 can dispense the liquid in the dissolving pot 50 to the dispensing bottles for use. Thus, the robotic arm 20, peristaltic pump 30 and dispensing pump 40 replace manual labor to complete the transfer, initial dissolution, dissolution and dispensing operations, which is highly efficient and low cost.

[0034] like Figure 3 As shown, the reagent preparation station also includes a heating module 60, on which a dissolving pot 50 is placed. The heating module 60 heats the liquid inside the dissolving pot 50. Optionally, the heating module 60 can be an induction cooker or a heating plate. During the preparation of culture media, it is often necessary to heat the solution. Therefore, the dissolving pot 50 is placed on the heating module 60, and the liquid level in the dissolving pot 50 is controlled by controlling the heating time and heating power. In one embodiment, to prepare for controlling the heating temperature, a temperature sensor is installed inside the dissolving pot 50. The heating module 60 is communicatively connected to the temperature sensor and controls the switch based on the temperature information fed back by the temperature sensor.

[0035] In one embodiment, the heating module 60 is integrated with the melting pot 50. For example, the melting pot 50 is an electric heating pot, and the integrated design simplifies the number of components on the operating table 10.

[0036] It should be noted that the open end of the dissolving pot 50 is equipped with a water inlet pipe, and a water inlet pump is installed on the water inlet pipe. After a reagent is diluted or a culture medium is prepared, the water inlet pump introduces clean water into the dissolving pot 50, which is then rinsed with clean water and the rinsing water is discharged by the dispensing pump 40, so that the dissolving pot 50 is ready for the preparation of the next reagent or culture medium.

[0037] In an optional embodiment, the bottom of the dissolving pot 50 is connected to an outlet pipe and a dispensing valve, a dispensing pump 40 is installed on the outlet pipe, and the dispensing valve is used to control the opening and closing of the outlet pipe.

[0038] A liquid outlet pipe is installed at the bottom of the dissolving pot 50, and a heating module 60 covers the outer side of the bottom of the dissolving pot 50. For example, the bottom of the dissolving pot 50 is frustoconical, with a liquid outlet at its smaller diameter end connected to the liquid outlet pipe. The heating module 60 is a heating plate that is attached to the outer wall of the dissolving pot 50. Alternatively, the bottom of the dissolving pot 50 may be flat, and the heating module 60 may be an electric heating plate or an induction cooker, with the bottom wall of the dissolving pot 50 attached to the heating module 60. A liquid outlet is provided on the side wall of the dissolving pot 50 near the bottom wall to connect to the liquid outlet pipe. The dispensing pump 40 ensures that all liquid in the dissolving pot 50 is discharged through suction. Optionally, the dispensing valve is a solenoid valve.

[0039] like Figure 1 and Figure 3 As shown, the reagent preparation station also includes a weighing platform 70, which is fixed to the operating table 10. The robotic arm 20 can move beakers from the beaker placement area to the weighing platform 70 to weigh a preset weight of culture medium.

[0040] Weighing platform 70 is an electronic scale, which is placed on the operating table 10 or embedded in the surface of the operating table 10. The electronic scale can be preset to automatically deduct the weight of the beaker; or it can directly weigh the total weight of the beaker and culture medium, and deduct the weight of the beaker when determining whether the weight of the culture medium has reached the preset weight.

[0041] In addition, the culture medium can also be packaged in grams. The weight of the culture medium can be controlled by adding the corresponding number of culture medium packages into the beaker, thus eliminating the need for a weighing platform 70. The culture medium can be added by means of a robotic arm 20.

[0042] In one specific embodiment, the reagent preparation station also includes a stirring rod, and a robotic arm 20 is used to hold the stirring rod and stir the liquid in the beaker and / or dissolving pot 50.

[0043] Optionally, the stirring rod can be made of glass or similar material, which will not be corroded by the dissolving solution or react with the culture medium. Normally, shaking the beaker with a robotic arm 20 for mixing can easily lead to spillage or uneven mixing. Therefore, this embodiment adds a stirring rod, which is held by the robotic arm 20 to simulate manual stirring of the liquid.

[0044] Specifically, the operating table 10 has a stirring rod placement area 13, and a tray is provided in the stirring rod placement area 13, with multiple stirring rods placed in the tray. Alternatively, a storage container is placed in the stirring rod placement area 13, with the stirring rods standing upright in the storage container. The robotic arm 20 moves the beaker to below the peristaltic pump 30 to receive the diluent. When receiving the diluent, the robotic arm 20 can either place the beaker below the peristaltic pump 30 or directly hold the robotic arm 20 below the peristaltic pump 30. While the robotic arm 20 is placing the beaker below the peristaltic pump 30 to receive the diluent, the robotic arm 20 can use the time while the beaker is receiving the diluent to pick up the stirring rod from the stirring rod placement area 13. After the diluent is added, the robotic arm 20 holds the stirring rod and directly stirs at that position. Of course, the robotic arm 20 can also move the beaker to the stirring area after receiving the diluent, and then pick up the stirring rod for stirring. With the robotic arm 20 directly holding the beaker below the peristaltic pump 30, after the diluent is added, the robotic arm 20 first transfers the beaker to the stirring zone, and then clamps the stirring rod from the stirring rod placement area 13 to stir the liquid in the beaker. Thus, the initial dissolution of the reagent is completed with the help of the robotic arm 20 and the stirring rod.

[0045] After mixing is complete, the robotic arm 20 will return the mixing rod to the mixing rod placement area 13 to await external robot recycling and cleaning, or to await the cleaning device set up in the workstation to clean the mixing rod.

[0046] It should be noted that when the initially dissolved liquid is poured from the beaker into the dissolving pot 50 and then returns to the peristaltic pump 30 to collect the diluted solution again, a stirring rod can be added to prevent the reagent from adhering to the beaker wall, or the stirring rod can be omitted. This embodiment of the invention does not specifically limit the scope of the invention in this regard.

[0047] In addition, during the dissolving process in the dissolving pot 50, the robotic arm 20 can hold the stirring rod for stirring. The stirring rod used in both the beaker and the dissolving pot 50 can be the same rod, which is only temporarily stored when returned to the stirring rod placement area 13. Taking the preparation of culture medium as an example, during the heating process, the liquid temperature is uneven throughout the dissolving pot 50, and the repeated pouring of liquid from the beaker into the dissolving pot 50 results in uneven distribution of the culture medium throughout the liquid. Therefore, the robotic arm 20 holds the stirring rod during the heating process to stir the liquid in the dissolving pot 50, promoting uniform mixing of the liquid within the dissolving pot 50.

[0048] Furthermore, the reagent preparation station also includes a cleaning pump, water pipes, and a cleaning tank. The cleaning pump is connected to the water pipes, with the water outlet facing the cleaning tank. The robotic arm 20 is used to transfer the stirred rods to the cleaning tank for cleaning. The bottom of the cleaning tank is equipped with a drain pipe.

[0049] Optionally, a cleaning tank is located in the stirring rod placement area 13. This serves two purposes: firstly, the stirring rod is temporarily stored in the cleaning tank; secondly, after dissolution, a cleaning pump can pump clean water into the cleaning tank to clean the stirring rod. In one embodiment, during the cleaning process, the robotic arm 20 holds the stirring rod at the water outlet of the water pipe, allowing the clean water discharged from the outlet to directly rinse the stirring rod. During the cleaning process, the drain pipe is open, and water flows directly out. To ensure the cleanliness of the stirring rod, the duration of water rinsing the stirring rod in the water pipe can be controlled. In another embodiment, a cleaning pump pumps clean water into the cleaning tank. After a preset amount of clean water accumulates in the cleaning tank, the robotic arm 20 holds the stirring rod and stirs it to achieve cleaning. A valve is installed on the drain pipe; the valve is closed while clean water accumulates in the cleaning tank. After cleaning, the valve opens to discharge the wastewater from the cleaning tank. In this embodiment, to ensure the cleanliness of the stirring rod, clean water can be collected in the cleaning tank after the wastewater is discharged through the drain pipe for a second stirring and cleaning. This increases the number of stirring and cleaning cycles to ensure the cleanliness of the stirring rod.

[0050] The reagent preparation station also includes a stirrer, which is installed on the operating table 10. The robotic arm 20 is used to transfer the beaker containing the initial dilution solution to the stirrer for mixing. The stirrer can automatically perform the mixing without the need for the robotic arm 20, thereby reducing the amount of movement required by the robotic arm 20.

[0051] In use, the robotic arm 20 grips the beaker and moves it below the peristaltic pump 30 to receive the diluent, then transfers it to the stirrer for mixing. In this embodiment, the stirrer is fixed on the operating table 10 and is only used to stir the liquid in the beaker; it cannot stir the liquid in the dissolving pot 50. Therefore, a stand is fixedly installed beside the dissolving pot 50, and a rotary motor is mounted on the stand. The motor shaft of the rotary motor is fixedly connected to the stirring shaft, the end of which is inserted into the dissolving pot 50. Thus, automatic stirring of the liquid in the dissolving pot 50 can be achieved by means of the rotary motor and the stirring shaft. The stirring shaft may have fan blades; alternatively, the stirring shaft may be ball-shaped. Furthermore, a rinsing device is installed on the stand, which can spray water onto the stirring shaft to clean it.

[0052] In one embodiment, the stirrer includes a mounting bracket, a stirring head, a rotary drive component, and a rinsing pipe. The mounting bracket is fixed to the operating table 10, the rotary drive component is mounted on the mounting bracket, the drive end of the rotary drive component is connected to the stirring head, and the rinsing pipe is located beside the stirring head.

[0053] The mounting bracket is bolted to the operating table 10. Optionally, the mounting bracket has a mounting area suspended above the operating table 10, and a rotary drive is fixed to the mounting area. The rotary drive passes through the mounting area and is directly connected to the stirring head. The robotic arm 20 holds the beaker and moves it below the stirring head so that the stirring head contacts the liquid in the beaker. Then, the rotary drive drives the stirring head to rotate and mix the liquid in the beaker. Alternatively, the rotary drive can be mounted on the mounting bracket in a height-adjustable manner, thereby enabling the stirring head to be raised and lowered. In use, the robotic arm 20 holds the beaker, moves it below the stirring head, and places it on the operating table 10. Then, the rotary drive moves down, causing the stirring head to insert into the beaker to stir the liquid inside. After stirring is complete, the rotary drive rises, removing the stirring head from the beaker, and the robotic arm 20 removes the partially dissolved beaker from below the stirring head.

[0054] Optionally, the rotary drive component can be a servo motor or a pneumatic structure that enables rotary drive.

[0055] The reagent preparation station also includes a support base on which multiple peristaltic pumps 30 are installed. Each peristaltic pump 30 is connected to a corresponding reagent container 80, and the reagents contained in the multiple reagent containers 80 are different.

[0056] Specifically, the support base is fixed to the operating table 10 by bolts. It has a plate suspended above the operating table 10, and the plate has multiple insertion holes. The outlet end of the peristaltic pump 30 is inserted into the insertion holes. The robotic arm 20 moves the beaker below the plate and aligns it with the peristaltic pump 30 corresponding to the required reagent. Then, the peristaltic pump 30 is turned on to add the required reagent into the beaker.

[0057] Multiple reagent containers 80 are placed on the operating table 10, located below it. Alternatively, the reagent containers 80 can be positioned above the operating table 10, such as by being fixed to a support frame. Each reagent container 80 is connected to a peristaltic pump 30 via infusion tubing, and different reagents are contained within each container. Water is used as a diluent in one of the reagent containers 80. One of the peristaltic pumps 30 is directly connected to the indoor water supply system, eliminating the need for water replenishment and simplifying station maintenance. Each reagent container 80 is equipped with a peristaltic pump 30. When dilution of a reagent is required, the robotic arm 20 moves a beaker to the peristaltic pump 30 corresponding to the desired reagent, receives the reagent, and then moves it to the peristaltic pump 30 corresponding to the diluent to receive the diluent. When preparing culture media, the initial step is weighing. The robotic arm 20 moves a beaker to a weighing platform 70 to weigh the target weight of the culture media before moving it to the peristaltic pump 30 corresponding to the diluent to receive the diluent.

[0058] The robotic arm 20 can directly hold the dispensing bottle and move it to the peristaltic pump 30 to receive the reagent to be diluted, and then transfer it to the peristaltic pump 30 corresponding to the diluent to receive the diluent. Then, a stirrer or stirring rod will thoroughly mix the liquid in the dispensing bottle to complete the reagent preparation, eliminating the need for a dispensing step. Alternatively, the reagent can be mixed thoroughly in the dissolving vessel 50 and then dispensed via the dispensing pump 40.

[0059] There are five peristaltic pumps 30, three of which are located on the same side of the robotic arm 20 as the sample bottle placement area 12, and the other two are located on the other side of the robotic arm 20. Figure 3 As shown, there are three reagent containers 80: one container holds phosphate, one holds sodium chloride, and the third holds water as a diluent. Three peristaltic pumps 30, located on the same side of the robotic arm 20 as the sample bottle placement area 12, are connected to the reagent containers 80 containing phosphate, sodium chloride, and diluent, respectively. Two peristaltic pumps 30 located on the right side of the robotic arm 20 are connected to the reagent container 80 containing diluent, providing diluent for dissolving the culture medium.

[0060] like Figures 1 to 3 As shown, the reagent preparation station also includes a control device, which includes an input device, a processor, and a display screen 91. The input device allows the user to input operation commands to the processor, and the processor is connected to the display screen 91. The display screen 91 is placed on the operating table 10 and is used to display the processor's processing results and guide the user to input corresponding operation commands.

[0061] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
