[0049] In a specific embodiment, see Figure 1 , the filter press system includes:

[0050] A filter bottle group transfer module 11 is provided with a filter press position 12 at one end portion in the Y-axis direction, and the filter bottle group transfer module 11 is used to drive a filter bottle group carrier 13 to move in the Y-axis direction; the filter bottle group carrier 13 is used to load a filter bottle group, and the filter bottle group includes a first filter bottle 14 and a second filter bottle 15, and the first filter bottle 14 is connected to the second filter bottle 15 through a set filter membrane; specifically, the filter bottle group transfer module 11 can be a synchronous belt module, which can be driven in a variety of ways and combinations thereof, not limited to a synchronous belt module, and can also be driven by a cylinder, an electric cylinder or a screw module.

[0051] Among them, see Figure 3 The filter press position 12 is a position near the end of one end of the filter press bottle group transfer module 11. First, the second filter press bottle 15 is installed in the filter press bottle group carrier 13, and then the filter press bottle group transfer module 11 drives the filter press bottle group carrier 13 to move to the filter press position 12, and the filter press transfer module 31 clamps the first filter press bottle 14 to complete the filtration at the filter press position 12.

[0052] In one specific embodiment, see Figure 7 , the first filter press bottle 14 can be an inner filter press bottle, the second filter press bottle 15 is an outer filter press bottle, and the inner filter press bottle is nested in the outer filter press bottle. Specifically, a first bearing portion for placing a filter press membrane is provided at the bottom of the first filter press bottle 14, and a reinforcing rib is also provided at the connection between the filter press membrane and the first filter press bottle.

Placing the filter press membrane on the first bearing portion can improve the accuracy of the position of the filter press membrane when it is fixed, and the filter press ensures the accuracy of the filter press. The bottom of the second filter press bottle 15 is sealed. In this embodiment, the second filter press bottle 15 contains the reaction liquid, the first filter press bottle 14 is pressed into the second filter press bottle 15, and the reaction liquid enters the first filter press bottle 14 through the filter press membrane. In another specific embodiment, the bottom of the first filter press bottle 14 is sealed with a bearing membrane, and the second filter press bottle 15 is provided with a second bearing portion for placing the filter press membrane at a position away from the bottom. In this embodiment, the first filter press bottle 14 contains the reaction liquid, the first filter press bottle 14 is pressed into the second filter press bottle 15, and the reaction liquid enters the second filter press bottle 15 through the filter press membrane. The filter press membrane is a one-way filter membrane, which can make the reaction liquid contained in the first filter press bottle 14 flow to the second filter press bottle 15, and can also make the reaction liquid contained in the second filter press bottle 15 flow to the first filter press bottle 14. The above two embodiments can use one-way filter membranes in different directions; the material of the one-way filter membrane can be selected according to different sample characteristics, for example, it can be selected from polytetrafluoroethylene or polyamide.

[0053] In a specific embodiment, see Figure 2 The filter bottle group carrier 13 includes a first filter bottle carrier and a second filter bottle carrier, wherein the number of filter bottle group transfer modules 11 is at least two, and the first filter bottle carrier and the second filter bottle carrier can be arranged on the same filter bottle group transfer module 11, or can be arranged on different filter bottle group transfer modules 11. The first filter bottle carrier and the second filter bottle carrier are divided into a plurality of accommodating cavities, and the outer contour of the accommodating cavity is slightly larger than the outer diameter of the first filter bottle 14 and the second filter bottle 15. Preferably, the shape of the accommodating cavity is circular or square, so that the first filter bottle 14 and the second filter bottle 15 can be conveniently placed in the accommodating cavity, so that the first filter bottle 14 and the second filter bottle 15 can be placed more stably and not easily overturned.

[0054] The pipetting and loading module 21 is used to drive the pipetting component 22 containing the reaction liquid to move in a first preset direction, and the first preset direction includes the X-axis direction and the Y-axis direction. When the pipetting component 22 moves to the top of the filter bottle group, the controller controls the pipetting component 22 to inject the reaction liquid into the target filter bottle; the target filter bottle is the first filter bottle or the second filter bottle; specifically, when a filter membrane is provided at the bottom of the first filter bottle 14, the pipetting component 22 injects the reaction liquid into the second filter bottle 15; when a carrying membrane is provided at the bottom of the first filter bottle 14, When the second filter press bottle 15 is provided with a filter press membrane at a position away from the bottom, the liquid transfer assembly 22 injects the reaction liquid into the first filter press bottle 14; wherein, the filter press bottle group transfer module 11 comprises a first motor and a first synchronous belt, the filter press bottle group carrier 13 is placed on the first synchronous belt, the first motor drives the first synchronous belt to move, and the filter press bottle group carrier 13 carries the second filter press bottle 15, so that the filter press bottle group carrier 13 placed on the first synchronous belt moves to the filter press position 12, and then the second filter press bottle 15 carried in the filter press bottle group carrier 13 moves to the filter press position 12;

[0055] Among them, the pipetting component 22 is controlled by a controller to inject the reaction liquid into the target filter press bottle. The controller is the control center of the entire filter press system equipment, which is used to issue work instructions to the corresponding modules in a timely manner to achieve collaborative work between the modules. For example, the controller can adopt one or more of PLC, microcomputer, computer control software, etc. The pipetting component 22 includes a pipetting gun and a Tip head connected to the pipetting gun. The Tip head is also called a liquid suction head or a pipetting head. It is a pipetting tip for experiments, which belongs to a consumable material and can store a certain volume of liquid. The Tip head is placed in the Tip head bin, and the end of the pipette gun is provided with a joint part that cooperates with the Tip head. The pipette gun moves to the Tip head bin, providing a downward impulse to cooperate with the Tip head through the joint part. After the Tip head is installed on the pipette gun, the pipette gun provides a suction force to suck the reaction liquid into the Tip head for storage, and then the pipetting and loading module 21 drives the pipetting component 22 containing the reaction liquid to move to the target filter bottle, and the pipette gun spits out the liquid. The Tip head injects the stored reaction liquid into the target filter bottle to complete the suction and spits operation; the number of pipetting components can be multiple groups, for example, three groups, so that it can correspond to 3 solutions, and different solutions can be pipetted at the same time, meeting high-throughput requirements and realizing batch pipetting operations. Among them, the pipette gun can be replaced by a syringe pump or a peristaltic pump.

[0056] In other embodiments, the first preset direction may include the X-axis direction, the Y-axis direction, and the Z-axis direction. As an example, after the liquid transfer module 21 drives the liquid transfer component 22 containing the reaction liquid to move to the target filter press bottle along the X-axis direction and the Y-axis direction, the liquid transfer module 21 can drive the tip head to move along the Z-axis direction to the vicinity of the bottle mouth of the target filter press bottle through the liquid transfer component 22 controller, thereby completing the liquid suction and discharge operation. The X-axis, Y-axis, and Z-axis directions described in this application are perpendicular to each other.

[0057] The filter press transfer module 31 is used to drive the first clamping device 32 to move in the second preset direction to clamp the first filter press bottle 14 and move it to the filter press position 12. The second preset direction includes the X-axis direction and the Z-axis direction. It cooperates with the second filter press bottle 15 moved to the filter press position 12, and applies pressure to the second filter press bottle 15 through the first filter press bottle 14 so that the reaction liquid in the target filter press bottle is filtered through the filter press membrane. Specifically, when a filter press membrane is provided at the bottom of the first filter press bottle 14, the first filter press bottle 14 applies pressure to the second filter press bottle 15 so that the reaction liquid in the second filter press bottle 15 is filtered through the filter press membrane and enters the first filter press bottle 14; when a supporting membrane is provided at the bottom of the first filter press bottle 14, and a filter press membrane is provided at the position of the second filter press bottle 15 away from the bottom, the first filter press bottle 14 applies pressure to the second filter press bottle 15 so that the reaction liquid in the first filter press bottle 14 is filtered through the filter press membrane and enters the second filter press bottle 15.

[0058] In a specific embodiment, the working mode of the filter press system is as follows: the pipetting component 22 containing the reaction liquid is driven to move to the top of the filter press bottle group by the pipetting and loading module 21, and the controller controls the pipetting component 22 to inject the reaction liquid into the second filter press bottle 15; the filter press bottle group carrier 13 is loaded with the second filter press bottle 15 injected with the reaction liquid, and the filter press bottle group loading module 11 drives the filter press bottle group carrier 13 to move to the filter press position 12; the filter press loading module 31 drives the first clamping device 32 to clamp the first filter press bottle 14 and move it to the filter press position 12, cooperate with the second filter press bottle 15 located at the filter press position 12, and apply pressure to the second filter press bottle 15 through the first filter press bottle 14, so that the reaction liquid in the second filter press bottle 15 enters the first filter press bottle 14 through the filter press membrane to complete the filtration. In another specific embodiment, the working mode of the filter press system is that the pipetting assembly 22 containing the reaction liquid is driven to move to the top of the filter press bottle group by the pipetting and loading module 21, and the controller controls the pipetting assembly 22 to inject the reaction liquid into the first filter press bottle 14; the filter press bottle group carrier 13 is loaded with the second filter press bottle 15, and the filter press bottle group loading module 11 drives the filter press bottle group carrier 13 to move to the filter press position 12; the filter press loading module 31 drives the first clamping device 32 to clamp the first filter press bottle 14 and move it to the filter press position 12, and cooperate with the second filter press bottle 15 located at the filter press position 12, and apply pressure to the second filter press bottle 15 through the first filter press bottle 14, so that the reaction liquid in the first filter press bottle 14 enters the second filter press bottle 15 through the filter press membrane to complete the filter press. The present application is not limited to the order of the above operations, that is, those skilled in the art can also select a suitable judgment order or perform several operations and steps simultaneously according to needs, and the present application may not be limited to this.

[0059] In a specific embodiment, see Fig.10 and Fig.11The first clamping device 32 includes a first gripper 321 and a first clamping finger 322. The first gripper 321 can be an electric gripper or an air gripper. The first clamping finger 322 is installed on the first gripper 321. The opening and closing of the first clamping finger 322 is controlled by the first gripper 321. The shape of the first clamping finger is L-shaped, and the number is at least two. The first clamping fingers 322 arranged corresponding to each other can be arranged to be able to approach each other to clamp the first filter press bottle 14 or the second filter press bottle 15, and can be able to move away from each other to release the first filter press bottle 14 or the second filter press bottle 15. Specifically, the first clamping finger 322 includes a mounting plate and a clamping plate connected to the mounting plate. The shorter side of the first clamping finger 322 protruding outward is the mounting plate, and the end of the clamping plate away from the mounting plate is provided with a filter press; the filter press can be, for example, a part of a spatial structure capable of defining a space for clamping the first filter press bottle 14 or the second filter press bottle 15, and pressing the first filter press bottle 14 down into the second filter press bottle 15, such as a groove, a cavity, a blind hole, and the like. In some embodiments, the filter press can be a groove, and the groove includes a pressure-bearing surface 3221 and a supporting surface 3222. The supporting surface 3222 is used to clamp the first filter press bottle 14. The two grooves cooperate with each other to form a cavity structure to clamp the first filter press bottle 14. Preferably, the shape of the cavity structure is a polygon, so as to ensure coaxiality. The pressure-bearing surface 3221 is used to press the first filter press bottle 14 down into the second filter press bottle 15 to bear axial pressure. This makes the clamping more stable and balanced, and not easy to tilt.

[0060] In a specific embodiment, see Figure 1 , 2 The filter press system further includes an analysis plate transfer module 16, which is used to drive the analysis plate 17 to move in the Y-axis direction.

[0062] Among them, the analysis disk transfer module 16 can be a synchronous belt module, which can be driven in a variety of ways and combinations thereof, not limited to the synchronous belt module, and can also be driven by a cylinder, an electric cylinder or a screw module. Preferably, the analysis disk transfer module 16 includes a second motor and a second synchronous belt, and the analysis disk 17 is placed on the second synchronous belt. The second synchronous belt is driven by the second motor to move along the Y-axis direction, thereby driving the analysis disk 17 located on the second synchronous belt to move. The analysis disk 17 is divided into a plurality of accommodating chambers for loading the filter press bottle group. The analysis disk transfer module 16 drives the analysis disk 17 loaded with the filter press bottle group to move; the outer contour of the accommodating chamber is slightly larger than the outer diameter of the second filter press bottle 15. Preferably, the accommodating chamber is circular or square, which is convenient for the filter press bottle group to be placed in the accommodating chamber, so that the filter press bottle group is placed more stably and is not easy to overturn.
