[0036] See also Figure 1 , Figure 1 A schematic diagram of the main structure of a liquid dispensing station provided for an embodiment of the utility model; the liquid dispensing station can be used in scenarios where liquid needs to be pumped, which simplifies the liquid pumping process and facilitates operation; the structure is fixed and stable, and part of the structure can be moved, which is more flexible and convenient; the reasonable structural layout makes the structure more space-saving.

[0037] See also Figure 1 A liquid dispensing station includes a control unit, a shell 60, a peristaltic pump pipeline mounting structure and a liquid bag pipeline loading structure 70; an opening is provided on one side of the shell 60, the peristaltic pump pipeline mounting structure is installed in the shell 60, and the liquid bag pipeline loading structure 70 is installed on the side of the shell 60 where the opening is provided; the peristaltic pump pipeline mounting structure includes a peristaltic pump tube group, and the peristaltic pump tube group is connected to the liquid bag pipeline loading structure 70; the control unit is installed on the shell 60, and the control unit is connected to the peristaltic pump pipeline mounting structure; by operating the control unit, the peristaltic pump pipeline mounting structure is automatically controlled to control the peristaltic pump to pump liquid, control the opening and closing of the clamping valve structure corresponding to different processes, and then control the flow direction of the pipeline.

[0038] In this embodiment, the user can control the peristaltic pump to pump liquid by operating the control unit, and can also control the opening and closing of the pinch valve structure required for different processes. When the control unit is started, it sends a command to the peristaltic pump pipeline installation structure, instructing it to start pumping liquid. At the same time, the control unit will also control the opening and closing of the pinch valve structure according to the user-set or pre-set process requirements to adjust the flow direction of the pipeline, so as to transport the liquid to the required location.

[0039] Through the operation of the control unit, the peristaltic pump and pipeline flow direction are automatically controlled, reducing the need for manual operation. The pumping and flow direction of the liquid can be accurately controlled according to the needs of the user to ensure the accuracy and stability of the liquid preparation process. The automated operation method can improve the efficiency of liquid preparation and save time and labor costs. The working mode and parameter settings of the liquid preparation station can be flexibly adjusted according to different application scenarios and needs.

[0040] Specifically, see Figure 3 The control unit includes a control panel 65, which is embedded in a housing 64. There is a control panel baffle 66 inside the housing, which is connected to the housing by screws and plays the role of fixing the control panel 65. In this way, the control panel 65 is firmly installed inside the housing. There is a rotating shaft on the housing 64, which is fixed to the shell 60, so that the control panel 65 can rotate. It can be completely retracted into the shell 60 and flush with the shell 60, or it can be rotated out and parallel to the front of the shell 60 for easy operation. In addition, it also has a locking function to maintain its stability when the control panel 65 is pressed.

[0041] See also Figure 4 and Figure 5 A peristaltic pump pipeline installation structure includes: a fixing plate 33, a consumables installation plate 10 and a peristaltic pump tube assembly; the peristaltic pump tube assembly includes a peristaltic pump tube group 20 and a pipeline installation plate 21, the pipeline installation plate 21 is provided with an installation groove, the peristaltic pump tube group 20 is installed on a side surface of the pipeline installation plate 21, and the peristaltic pump tube group 20 is installed in the installation groove; the pipeline installation plate 21 is installed on the consumables installation plate 10. The consumables installation plate 10 is connected to the fixing plate 33, and the fixing plate 33 is connected to the housing 60.

[0042] In this embodiment, through the design of the mounting groove and the mounting plate, the peristaltic pump tube group 20 can be firmly installed in position to ensure that it will not move or swing during operation, thereby ensuring the stable operation of the pump. Since the peristaltic pump tube group 20 is installed on the pipeline mounting plate 21, it can be relatively easy to operate when maintenance or replacement of the hose is required without disassembling the entire pump structure. By installing the pipeline mounting plate 21 on the consumable mounting plate 10, the space can be effectively utilized, making the layout of the entire peristaltic pump 32 system more compact and suitable for various environments and scenarios. The structure adopts a modular design, which makes the assembly process of the peristaltic pump 32 simpler and faster, saving time and labor costs.

[0043] In general, this peristaltic pump 32 installation structure has the advantages of high stability, easy maintenance, high space utilization and simple assembly, and can meet the needs of liquid transportation in various industrial and laboratory scenarios.

[0044] In one embodiment, see Figure 5 and Figure 7 The two ends of the pipeline mounting plate 21 are respectively connected to the consumable mounting plate 10 through fixing clips 11.

[0045] In one embodiment, see Figure 5 and Figure 7 A limiting support plate 12 is installed at the lower end of the above-mentioned consumable mounting plate 10, and limiting plates 13 are installed on both sides of the consumable mounting plate 10 respectively, and the limiting support plate 12 is connected to the limiting plates 13; the pipeline mounting plate 21 is placed between the two limiting plates 13; the lower end of the pipeline mounting plate 21 is in contact with the limiting support plate 12.

[0046] In one embodiment, see Figure 5 and Figure 7 The consumables mounting plate 10 is provided with a positioning pin 14, and the pipeline mounting plate 21 is provided with a positioning hole, and the positioning pin 14 is inserted into the positioning hole.

[0047] The fixed clip 11 is similar to a clip and is fixed to the consumable mounting plate 10 by screws. The peristaltic pump tube is installed according to the fixed template of the pipeline mounting plate 21 and connected by a three-way connector to form a peristaltic pump tube group 20 with multiple inlet and outlet channels. Such a structure enables a set of consumables to be used for the preparation of multiple liquids and multiple processes. The peristaltic pump tube group 20 is embedded in the pipeline mounting plate 21, and the pipeline mounting plate 21 is installed to the specified position. Its installation position is determined by the positioning pin 14 and the limit plate 13, and finally it is fixed in the specified position by the fixed clip 11 to keep it stable and stationary. This installation method ensures the stability and reliability of the peristaltic pump 32 system during operation, while providing a flexible liquid handling solution suitable for a variety of experimental and industrial application scenarios.

[0048] In one embodiment, see Figures 4 to 7 The above-mentioned peristaltic pump pipeline installation structure also includes a driving motor 30, the driving motor 30 is connected to a motor flange 31, the motor flange 31 is connected to a fixing plate 33, the driving motor 30 is connected to a peristaltic pump 32, and the peristaltic pump 32 is connected to the peristaltic pump tube group 20.

[0049] In this embodiment, the fixing plate 33 is used to stabilize the entire device, confirm the positions of multiple pinch valves, and fix them to the mounting plate with screws. The driving motor 30 of the peristaltic pump 32 is connected to the motor flange 31 and fixed to the fixing plate 33, and the peristaltic pump 32 is connected to the motor flange 31. Such a design ensures the stability and reliability of the entire system, so that the peristaltic pump 32 can effectively drive the liquid flow, and the pinch valve can flexibly control the flow of each channel to meet different process requirements.

[0050] In one embodiment, see Figures 4 to 8 The above-mentioned peristaltic pump pipeline installation structure also includes a guide shaft 40, and two linear bearings 34 arranged at intervals are installed on the fixed plate 33; one end of the guide shaft 40 passes through the fixed plate 33 and is connected to the consumable installation plate 10; the guide shaft 40 is connected to the linear bearing 34.

[0051] In this embodiment, every three guide shafts 40 form a group, cooperate with a linear bearing 34 , and are connected to a rear limit plate 42 to ensure the movement stability of the guide shafts 40 .

[0052] In one embodiment, see Figures 4 to 8 A spring 41 is installed on the guide shaft 40, one end of the spring 41 is connected to the consumable mounting plate 10; the other end of the spring 41 is connected to the fixing plate 33; the other end of the guide shaft 40 is connected to the rear limit plate 42.

[0053] In this embodiment, two linear bearings 34 are installed on the fixed plate 33 at intervals, and one end of the guide shaft 40 passes through the fixed plate 33 and is connected to the consumable mounting plate 10. Such a design enables the consumable mounting plate 10 to be pushed in and pulled out horizontally relative to the fixed plate 33.

[0054] A spring 41 is installed on the guide shaft 40, one end of which is connected to the consumable mounting plate 10 and the other end is connected to the fixed plate 33. Such an arrangement ensures that when the consumable mounting plate 10 is pushed into a specific position, the spring 41 can automatically push it out to maintain a good connection state. The consumable mounting plate 10 and the outer ring of the guide shaft 40 are covered with a spring 41, which is used to automatically push the consumable mounting plate 10 out. The other end of the three guide shafts 40 on one side is connected to the rear limit plate 42, which is used to limit the travel of the consumable mounting plate 10 to prevent the spring 41 from pushing the entire consumable mounting plate 10 out.

[0055] The design of the guide shaft 40 and the spring 41 ensures the stable pushing in and pulling out of the consumable mounting plate 10, making the operation smoother. The design of the spring 41 connection allows the consumable mounting plate 10 to be automatically pushed out when needed, so that the consumables in the pump system can be replaced or maintained conveniently and quickly. Through the rear limit connection of the guide shaft 40, the travel of the mounting plate can be limited to prevent the spring 41 from pushing out the entire consumable mounting plate 10, providing additional safety protection. Such a structural design makes the operation of the peristaltic pump system more efficient and reliable, while reducing the time cost of maintenance and replacement of consumables and improving work efficiency.

[0056] In summary, the structural design of the guide shaft 40 and the spring 41 adds stability, automation function and safety guarantee to the peristaltic pump installation structure, making the operation of the pump system more convenient and efficient.

[0057] In one embodiment, the fixing plate 33 is provided with a trunk lock, which is connected to the consumable mounting plate 10. The fixing plate 33 is provided with a trunk lock by screws, and is used to lock the consumable mounting plate 10 after pressing it so that it is fixed and does not pop out.

[0058] In one embodiment, see Figures 4 to 7 The above-mentioned peristaltic pump pipeline installation structure also includes a tube clamping valve structure 50. The fixed plate 33, the consumable installation plate 10 and the pipeline installation plate 21 are respectively provided with aligned through holes, and one end of the tube clamping valve structure 50 passes through the through holes in sequence; the tube clamping valve structure 50 is connected to the fixed plate 33.

[0059] The above-mentioned clamping valve structure 50 controls the expansion and contraction of the cylinder 51 to drive the coupling assembly. The coupling assembly has a certain buffer part, which converts the long stroke of the cylinder 51 into a short stroke at the end of the coupling assembly. The end of the coupling assembly drives the clamping assembly, and the connecting rod structure of the clamping assembly converts the linear expansion and contraction movement into the loosening or closing of the clamping block 532, so as to clamp the liquid pipe to block the flow of liquid. A solution is implemented to solve the problem of unstable operation and insufficient thrust by using pneumatic drive. By using the cylinder 51 as a driving device, the problems of insufficient motor thrust and inadequate stroke can be overcome, and the stability and reliability of the clamping valve can be improved.

[0060] In one embodiment, see Figure 8 and Fig. 9 The tube clamping valve structure 50 includes a cylinder 51, a coupling assembly, a tube clamping assembly and a protective cover 54. The cylinder 51 is connected to the coupling assembly; the coupling assembly is connected to the tube clamping assembly, and the tube clamping assembly is built into the protective cover 54. The tube clamping assembly includes a connecting rod structure and a tube clamping block 532, and the tube clamping block 532 is connected to the connecting rod structure; the connecting rod structure is connected to the coupling assembly, and the tube clamping block 532 is rotatably connected to the protective cover 54; the tube clamping assembly and the protective cover 54 pass through the through hole.

[0061] In this embodiment, when the cylinder 51 outputs thrust, the thrust is first transmitted to the coupling assembly, and then transmitted to the clamping assembly through the coupling assembly. After the thrust is applied, the clamping assembly rotates under the rotation connection with the protective cover 54, thereby realizing the function of clamping or releasing the liquid pipe by the clamping block 532.

[0062] In this embodiment, the protective cover 54 is built into the through hole of the pipeline installation plate 21; the shaft coupling structure is built into the fixing plate 33 and the consumable installation plate 10.

[0063] In one embodiment, see Fig.10 and Fig.11The above-mentioned cylinder 51 includes an output shaft 511; the coupling assembly includes a push rod sleeve 52 and a coupling push rod 521, one end of the push rod sleeve 52 is connected to the output shaft 511; one end of the coupling push rod 521 is built into the push rod sleeve 52, and one end of the coupling push rod 521 is connected to the clamping tube assembly.

[0064] In one embodiment, see Fig.10 and Fig.11 The above-mentioned coupling assembly also includes a limiting rod 522, which is installed between the push rod sleeve 52 and the coupling push rod 521.

[0065] Specifically, the cylinder 51 includes an output shaft 511, which is connected to the coupling assembly, and the thrust output by the cylinder 51 is transmitted to the coupling assembly. The coupling assembly includes a push rod sleeve 52 and a coupling push rod 521, one end of the push rod sleeve 52 is connected to the output shaft 511, and one end of the coupling push rod 521 is built into the push rod sleeve 52 and connected to the clamping tube assembly. The limit rod 522 is installed between the push rod sleeve 52 and the coupling push rod 521. Among them, the push rod sleeve 52 is sleeved on the outer ring of the coupling push rod 521, and is concentrically matched. The center has a limit rod 522 as the middle part connecting the clamping tube part and the cylinder 51. One end of the push rod sleeve 52 is connected to the output shaft 511 of the cylinder 51 by a thread, and the other end of the coupling push rod 521 is connected to the connecting block 53 of the clamping tube part by a pin.

[0066] It can be seen that the coupling part has a certain stroke buffer part, which is used to convert the large stroke of the cylinder 51 into the small stroke of the clamping part. The overall structural design enables the clamping valve to achieve a relatively large stroke conversion when the volume is relatively small, so that the movement of the clamping part can be controlled more flexibly and accurately in practical applications. The setting of the limit rod 522 also helps to control the stroke range of the clamping part, thereby improving the control accuracy and reliability of the clamping valve.

[0067] The overall volume of the pinch valve is small, but it can transform the large stroke of the cylinder 51 into a small stroke of the pinch part, thereby improving the compactness and efficiency of the system. The setting of the limit rod 522 and the design of the coupling part enable the pinch valve to achieve precise stroke control, meeting the requirements for high movement accuracy of the pinch part. By designing a reasonable coupling part, the stability and reliability of the pinch valve are enhanced, the service life is extended, and the maintenance cost is reduced.

[0068] In summary, the design of the pinch valve structure 50 can realize the conversion of a large stroke into a small stroke under the premise of a small volume, thereby improving the control accuracy and reliability, and is suitable for industrial application environments that require precise control.

[0069] In one embodiment, see Figures 10 to 12The above-mentioned connecting rod structure includes a connecting block 53 and a connecting rod 531. The connecting block 53 is connected to the connecting rod 521; one end of the tube clamping block 532 is connected to the connecting rod 521 through the connecting block 53, and the end of the tube clamping block 532 connected to the connecting block 53 is rotatably connected to the protective cover 54.

[0070] In one embodiment, see Figures 10 to 12 The number of the tube clamping blocks 532 is two; the two tube clamping blocks 532 are symmetrically arranged along the horizontal axis of the connecting block 53.

[0071] In one embodiment, see Figures 10 to 12 The connecting block 53 is connected to the connecting rod 521 via a pin.

[0072] In one embodiment, see Figures 9 and 10 The protective cover 54 is provided with a cavity for placing the pipe clamping block 532 .

[0073] In one embodiment, see Figures 9 and 10 One end of the clamping block 532 connected to the connecting block 53 is connected to the protective cover 54 through a pin.

[0074] In this embodiment, the connecting rod 531, the connecting block 53 and the tube clamping block 532 form a connecting rod structure, and the connecting rod 531 is connected to the push rod flat core and the tube clamping block 532 by a pin shaft connection. The tube clamping block 532 is fixed in the protective cover 54 and rotates around the pin shaft.

[0075] The clamp assembly adopts a connecting rod structure and is composed of small parts, which makes the overall volume small and suitable for places with limited space. The clamp valve can completely clamp the liquid pipe to ensure the blocking of liquid flow, has a large clamping force, and improves the stability and reliability of the clamp. The clamp assembly is designed with a large loose clamping angle, which will not affect the normal installation of the pipeline, ensuring the flexibility of the layout and connection of the pipeline.

[0076] In one embodiment, see Figures 9 to 12 The pinch valve structure 50 further includes a fixing block 55, one end of which is connected to the cylinder 51. The fixing block 55 is connected to the fixing plate 33.

[0077] In one embodiment, see Figures 9 to 12 , the coupling assembly is built into the fixed block 55.

[0078] In one embodiment, the protective cover 54 is fixed to the other end of the fixing block 55 and is fixed by screws to limit the clamping assembly and protect the connecting block 53 of the clamping assembly from being damaged by collision, thereby extending the service life.

[0079] In this embodiment, the above structure uses pneumatic elements to drive the internal mechanical structure to control the clamping block 532 to clamp or loosen, so that the clamping block 532 can clamp the liquid pipe. The structure is fixed and stable, which is more stable than the electric drive. The reasonable structural layout saves more space. Specifically, the connecting rod structure is used to convert the linear motion of the cylinder 51 into the rotational motion of the clamping part, thereby realizing the conversion of functions, thereby clamping the liquid pipe and blocking the flow of liquid. Through the design of the buffered coupling assembly and the connecting rod structure, the transmission of the movement of the cylinder 51 to the clamping assembly is realized in a smaller space, saving the installation space of the system. The use of the connecting rod structure can make the clamping force of the clamping assembly stable and reliable, ensuring the effect of clamping the pipe. It can overcome the problems of insufficient motor thrust and inadequate stroke, and improve the stability and reliability of the clamping valve.

[0080] The peristaltic pump tube is connected to the three-way joint according to the template to form a peristaltic pump tube group 20, and is embedded in the pipeline mounting plate 21.
