Description

Technical Field

[0001] The present invention relates to the technical field of experimental equipment, and in particular to a sample processing device. Background Art

[0002] In synthesis and drug development experiments, laboratory space is extremely valuable. Saving laboratory floor space can provide operators with more sufficient operating space. Operators have limited time and energy, so reducing the time and energy consumption of operators can greatly reduce safety hazards during the operation.

[0003] Firstly, when the operator is performing the operation, each step may need to be carried out in the corresponding fume hood, resulting in a huge amount of space occupied; secondly, the operator needs to spend a lot of time and energy to perform the operation, such as using a pipette to add liquid to the container containing the sample or pouring the sample (pouring the sample into the outer tube) and filter pressing (the same pressure is required to press the piston rod each time to filter the liquid in the sample in the outer tube out of the filter element), etc. Since the operator's operations such as adding liquid, pouring or filter pressing are not continuous, especially in the operation of filter pressing, which consumes a lot of physical energy, the high-intensity labor will cause the operator's concentration to decrease, physical overdraft, damage to experimental equipment, and even safety hazards.

[0004] However, the existing automated sample processing equipment that simulates the filter press operation, because the operation of pouring liquid into the outer sleeve and the operation of pressing the piston rod to filter the sample in the outer sleeve out of the filter element are performed in the same direction, the sample processing equipment occupies a huge space in this direction, and when performing the above two steps, the mechanical parts used for pouring liquid and the mechanical parts used for pressing the syringe piston are prone to interfere with each other. Summary of the invention

[0005] In order to at least partially solve the problems existing in the prior art, according to one aspect of the present invention, a sample processing device is provided, and the technical solution is as follows.

[0006] The sample processing device includes a front-end processing module, a pouring and filtering module and a back-end processing module; the front-end processing module is located upstream of the pouring and filtering module, and is used for preprocessing, and the preprocessing includes loading the first container, adding liquid, and shaking and centrifuging the sample in the first container. After the preprocessing is completed, the first container is placed in a first designated position; the pouring and filtering module has a moving part that is movable between a first position and a second position, and when the moving part is in the first position, the sample in the first container located at the first designated position is poured into the syringe, and when the moving part is in the second position, the sample poured into the syringe is filtered into the second container; the back-end processing module is located downstream of the pouring and filtering module, and is used for subsequent processing, and the subsequent processing includes transferring the sample in the second container, closing the cover of the second container and unloading.

[0007] In the sample processing device of the present invention, the front-end processing module, the pouring and filtering module and the back-end processing module are centrally arranged, which greatly improves the space utilization rate, realizes automated sample processing, reduces the time and energy consumption of operators, and improves the efficiency of sample processing, thereby avoiding the operator's physical overdraft due to high-intensity labor, causing damage to experimental equipment, and even the occurrence of safety hazards. Among them, the pouring and filtering module performs the dumping and filtering operations and is located at the first position and the second position respectively, converting the utilization of the space above the syringe into the utilization of the front space, avoiding the huge space occupied by the entire sample processing device in the same direction, and the pouring and filtering module performs the dumping and filtering operations at different positions respectively, avoiding the problem of interference between components.

[0008] Exemplarily, the moving part is formed by an outer sleeve clamping assembly, which is used to clamp the outer sleeve of the syringe, and the outer sleeve clamping assembly is movable between a first position and a second position along a first direction; the dumping filter module also has a piston plug-in assembly; the piston plug-in assembly is arranged above the outer sleeve clamping assembly, and can be raised and lowered relative to the outer sleeve clamping assembly along a second direction to separate the piston rod of the syringe from the outer sleeve or insert the piston rod into the outer sleeve, and the second direction is perpendicular to the first direction. Such an arrangement is based on the arrangement of the piston plug-in assembly and the outer sleeve clamping assembly. In the first position, the outer sleeve clamping assembly clamps the outer sleeve to clamp the syringe. Thereafter, the outer sleeve clamping assembly drives the syringe to move to the second position. In the second position, the piston plug-in assembly rises, and the piston plug-in assembly separates the outer sleeve from the piston rod. Subsequently, the outer sleeve clamping assembly drives the outer sleeve back to the first position. In the first position, the sample in the first container located at the first designated position can be poured into the outer sleeve through the second conveying assembly; thereafter, the outer sleeve clamping assembly can drive the outer sleeve containing the sample to move back to the second position. In the second position, the filter press operation is performed: the piston plug-in assembly inserts the piston rod back into the outer sleeve and presses the liquid in the sample in the syringe covered with the filter element into the second container at the same time. After the filter press is completed, the discarded syringe can be discarded through the second conveying assembly. In this way, the second transport component can be conveniently cooperated to realize the automation of operations such as separating the syringe, pouring the sample, pressing the liquid in the sample in the syringe with the filter into the second container and discarding it, which greatly reduces manual labor and avoids the situation where the sample that is not fully dissolved is difficult to filter out. The operations of pouring and filtering are respectively located at the first position and the second position along the first direction, and the utilization of the space above the syringe (i.e., the space along the second direction) is converted into the utilization of the front space (i.e., the space along the first direction), saving the upper space occupied by the pouring and filter pressing module and greatly improving the space utilization rate. The pouring and filter pressing module can leave enough operating space for the second transport component, satisfying the degree of freedom required for the second transport component to perform the pouring operation.

[0009] Exemplarily, the outer sleeve clamping assembly includes a first clamping claw, a first driving member, and a second driving member. The first driving member and the first clamping claw are connected together by a first connecting member to drive the first clamping claw to switch between a folded state and a released state. The second driving member and the first clamping claw are connected together by a second connecting member to drive the first clamping claw to move between a first position and a second position along a first direction. In this way, the outer sleeve clamping assembly is moved between a first position and a second position along a first direction by the second driving member. The operations of pouring samples and pressing filters are performed at these two positions respectively. Compared with a device that performs the operations of pouring samples and pressing filters at the same position, the pouring and pressing filter module in the present invention converts the utilized space above the syringe into the utilized space in front, saving the upper space occupied by the pouring and pressing filter module, and greatly improving the space utilization rate.

[0010] Exemplarily, the first connecting member has a first end and a second end, the first end is fixedly connected to the first clamping claw, the second end is connected to the end of the first driving member through a sliding connection structure, and the second end can slide between a third position and a fourth position relative to the first driving member along a third direction, and the third direction is perpendicular to the first direction; when the first clamping claw is in a retracted state, the second end slides to the third position; when the first clamping claw is in a released state, the second end slides to the fourth position. In this way, through the first end and the second end of the first connecting member, the first driving member drives the first clamping claw to switch between the retracted state and the released state to clamp or release the syringe, and the first clamping claw, the first connecting member and the first driving member are split structures, which can be installed or disassembled, so as to facilitate replacement or maintenance.

[0011] Exemplarily, the second driving member has a main body and a telescopic body, the telescopic body extends or retracts relative to the main body along a first direction, and the second connecting member is arranged on the telescopic body. In this way, the second driving member can drive the first clamping claw to move between the first position and the second position through the telescopic body extending or retracting relative to the main body along the first direction, and perform a dumping operation or a filter pressing operation at the two positions along the first direction, thereby saving space for dumping the filter pressing module in the second direction, leaving enough operating space for the second transport assembly, satisfying the degree of freedom required for the second transport assembly to perform the dumping operation, and greatly improving the space utilization rate.

[0012] Exemplarily, the piston plug-in assembly includes a third driving member, a pushing member and at least two clamping claws. The third driving member is connected to the at least two clamping claws through a third connecting member to drive the clamping claws to clamp the piston rod or release the piston rod. The pushing member is arranged between the at least two clamping claws. With such an arrangement, the piston plug-in assembly can clamp the piston rod through the two clamping claws, and the end face of the end of the piston rod is abutted by the pushing member. When the piston plug-in assembly performs the action of pulling the piston rod out of the outer sleeve, the two clamping claws clamp the piston rod to drive it to rise. When the piston plug-in assembly performs the action of inserting the piston rod into the outer sleeve, the pushing member pushes the end face of the end of the piston rod to drive it to descend. Both actions can be achieved only through the piston plug-in assembly, saving costs.

[0013] Exemplarily, the piston plug-in assembly is connected to a lifting drive assembly, which includes a fourth drive member, a screw rod and a thrust plate. The fourth drive member drives the screw rod to drive the piston plug-in assembly and the thrust plate to lift and lower in the second direction. In this way, the thrust plate can be connected to the screw rod, and when the screw rod extends or retracts relative to the fourth drive member in the second direction, it can drive the thrust plate to lift and lower in the second direction. The thrust plate can be connected to the piston plug-in assembly, and in the process of the screw rod driving the thrust plate to lift and lower in the second direction, the thrust plate also drives the piston plug-in assembly to lift and lower in the second direction, thereby realizing automatic plugging and unplugging of the piston rod and saving manual labor.

[0014] Exemplarily, a pressure detection member is provided between the thrust plate and the end of the clamping claw, and the pressure detection member is used to detect the reaction force exerted on the piston rod. In this way, by providing the pressure detection member, when the piston rod is inserted into the outer sleeve (referred to as the insertion process for convenience), accurate feedback is provided for the pressure generated by the thrust plate, thereby ensuring smoothness during the insertion process and preventing the outer sleeve from being crushed due to excessive pressure.

[0015] Exemplarily, the thrust plate has a plate body and a pushing body, the plate body is connected to the screw rod, the pushing body extends from the plate body in a direction away from the screw rod, one end of the pressure detection member abuts against the pushing body, and the other end of the pressure detection member abuts against the end of the clamping claw through a connecting block. In this arrangement, by setting the pushing body, it is convenient to connect the pressure detection member with the thrust plate, and by setting the connecting block, it is convenient to connect the pressure detection member with the end of the clamping claw, thereby enhancing the firmness of the connection between the pressure detection member and the thrust plate and the end of the clamping claw.

[0016] Exemplarily, a piston rod clamping assembly is provided between the outer sleeve clamping assembly and the piston plug-in assembly, and the piston rod clamping assembly has two second clamping claws, and the two second clamping claws have a positioning and guiding state enclosed around the piston rod and an open state with a predetermined angle between them. After the piston plug-in assembly pulls the piston rod out of the outer sleeve to a predetermined height, the two second clamping claws are in the positioning and guiding state; when the piston plug-in assembly inserts the piston rod into the outer sleeve to squeeze out the liquid, the two second clamping claws are in the open state. With such a configuration, when the two second clamping claws of the piston rod clamping assembly are enclosed around the piston rod, the piston rod is positioned and guided, the piston rod is prevented from tilting, and the piston rod is ensured to be accurately inserted into the outer sleeve, thereby realizing accurate automated operation.

[0017] For example, the two second clamping claws are respectively provided with a plurality of first teeth and a plurality of second teeth. When the two second clamping claws are in a positioning and guiding state, the first teeth and the second teeth are staggered and closed, and a positioning and guiding cavity for the piston rod to pass through is formed between the two second clamping claws. With such a configuration, the piston rod is usually a cross structure, and the cavity wall of the positioning and guiding cavity formed by the two second clamping claws through the staggered closing of the first teeth and the second teeth has a smooth effect, thereby having a good positioning and guiding effect on the piston rod of the cross structure, ensuring that the piston rod can be accurately inserted into the outer sleeve.

[0018] Exemplarily, the dump filter press module further comprises a mounting plate, on one side of which a filter support plate is arranged, and the filter support plate is used to support the filter connected to the bottom of the outer sleeve. In this arrangement, the bottom of the outer sleeve clamped by the outer sleeve clamping assembly is connected to the filter, and the filter support plate is arranged to support the filter, so as to avoid shaking between the syringe and the filter during the filter pressing process, which leads to poor filter pressing effect.

[0019] For example, before the piston rod is separated from the outer sleeve, the piston rod is pressed by the piston plug-in assembly until the bottom of the outer sleeve is consistent with the installation height of the filter element. This arrangement ensures that there is no leakage at the connection between the syringe and the filter element during the filter press process, and the height of the piston rod is consistent each time it is pulled out.

[0020] Exemplarily, the dump filter press module further comprises a second container loading assembly, the second container loading assembly comprises an upper transport member and a lower receiving member, the lower receiving member is movable along the second direction between the receiving position and the loading position; the upper transport member transports the second container to the receiving position, and the second container is transported from the receiving position to the loading position through the lower receiving member. Such an arrangement realizes automatic loading of the second container, thereby improving efficiency and reducing labor costs.

[0021] Exemplarily, the front-end processing module includes a liquid adding component for adding liquid to the first container, and the liquid adding component includes a loading turntable and a liquid adding structure; a plurality of placement racks for fixing the first container are arranged on the loading turntable, and the loading turntable is arranged to rotate around the central axis so that each placement rack can rotate between the liquid adding position and the non-liquid adding position; the liquid adding structure is arranged above the loading turntable, and the liquid adding structure injects the solution into the first container when the placement rack rotates to the liquid adding position. In this arrangement, the loading turntable is arranged below the liquid adding structure, and the first container in the placement rack on the loading turntable is rotated between the liquid adding position and the non-liquid adding position in a rotating manner in conjunction with the rotation of the loading turntable around the central axis. On the basis that the liquid adding structure has sufficient movement space, the spacing between the first containers is reduced, and the space below the liquid adding structure is effectively utilized, thereby improving the space utilization rate, making the entire device more compact and convenient to use in a small space.

[0022] A series of simplified concepts are introduced in the summary of the invention, which will be further described in detail in the detailed description. The summary of the invention does not mean to attempt to define the key features and essential technical features of the claimed technical solution, nor does it mean to attempt to determine the scope of protection of the claimed technical solution.

[0039] In the following description, a large amount of details are provided so that the present invention can be thoroughly understood. However, it will be appreciated by those skilled in the art that the following description only exemplarily illustrates a preferred embodiment of the present invention, and the present invention can be implemented without one or more such details. In addition, in order to avoid confusion with the present invention, some technical features well known in the art are not described in detail.

[0040] In order to fully understand the embodiments of the present invention, detailed structures will be presented in the following description. Obviously, the implementation of the embodiments of the present invention is not limited to the specific details familiar to those skilled in the art. The preferred embodiments of the present invention are described in detail below, but in addition to these detailed descriptions, the present invention may also have other embodiments.

[0041] An embodiment of the present invention provides a sample processing device. The sample processing device according to the embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0042] Combined with reference Figure 1 , Figure 2 , Figure 3 and Figure 6, the sample processing device 1 may include a front-end processing module 10, a pouring filter module 20 and a back-end processing module 30. The front-end processing module 10 may be located upstream of the pouring filter module 20 for pretreatment, and the pretreatment may include one or more operations of loading the first container 40, adding liquid, and shaking and centrifuging the sample in the first container 40, and placing the first container 40 in the first designated position 106 after the pretreatment is completed. That is to say, the pretreatment may include one or more of the four operations of loading, adding liquid, shaking and centrifuging. Specifically, the pretreatment may be a processing operation before the filter press process. In one embodiment, the pretreatment includes loading the first container 40, scanning the code, adding liquid to dissolve the sample in the first container 40, heating and shaking, centrifuging, and the like. The first container 40 may be a sample bottle or a sample tube containing a solid sample. In another embodiment, the pretreatment may include loading and adding liquid to the first container. The pouring filter press module 20 may have a moving part that is movable between a first position and a second position, and when the moving part is in the first position, the sample in the first container 40 located at the first designated position 106 can be poured into the syringe 60, and when the moving part is in the second position, the sample poured into the syringe 60 can be filtered into the second container 50. The pouring filter press module 20 may also have a second transport component 201, which may be used to perform the operation of pouring the sample in the first container 40 into the syringe 60. The first designated position 106 may be a position or area for placing the first container 40 after pretreatment and preparing for the second transport component 201 to carry. It should be noted that before pretreatment, the sample in the first container 40 may be a solid or a solid-liquid mixture doped with a small amount of liquid, after pretreatment, the sample in the first container 40 may be a solid-liquid mixture, and after filter pressing, the sample entering the second container 50 may be a liquid or a solid-liquid mixture doped with a small amount of solid. The back-end processing module 30 can be located downstream of the dumping filter module 20 for subsequent processing, which can include transferring the sample in the second container 50, closing the cover of the second container 50, and unloading. The subsequent processing can be a processing operation after the filter pressing process, for example, after the filter pressing process, it is necessary to transfer the sample in the second container 50, close the cover of the second container 50, spray code on the bottle body and bottle cap of the second container 50, and unload the material. In one embodiment, the subsequent processing can also include spraying code on the second container 50. The second container 50 can be a sample bottle or a reagent tube, etc. Understandably, the upstream mentioned above can be the operating position before the filter pressing process, and the downstream can be the operating position after the filter pressing process.

[0043] In the sample processing device 1 of the present invention, the front-end processing module 10, the pouring and filtering module 20 and the back-end processing module 30 are centrally arranged, which greatly improves the space utilization rate, realizes automated sample processing, reduces the time and energy consumption of operators, and improves the efficiency of sample processing, thereby avoiding the operator's physical overdraft due to high-intensity labor, causing damage to experimental equipment, and even the occurrence of safety hazards. Among them, the pouring and filtering module 20 performs the pouring and filtering operations and is located at the first position and the second position respectively, converting the utilization of the space above the syringe 60 into the utilization of the front space, avoiding the huge space occupied by the entire sample processing device 1 in the same direction, and the pouring and filtering module 20 performs the pouring and filtering operations at different positions respectively, avoiding the problem of interference between components.

[0044] Combined with reference Figures 1 to 3, the moving part can be formed by the outer sleeve clamping assembly 210. The outer sleeve clamping assembly 210 can be used to clamp the outer sleeve 610 of the syringe 60, and the outer sleeve clamping assembly 210 can be movable between a first position and a second position along a first direction X. The dumping filter module 20 can also have a piston plug assembly 220. The piston plug assembly 220 can be arranged above the outer sleeve clamping assembly 210, and can be lifted and lowered relative to the outer sleeve clamping assembly 210 along a second direction Y to separate the piston rod 620 of the syringe 60 from the outer sleeve 610 or insert the piston rod 620 into the outer sleeve 610. The second direction Y can be perpendicular to the first direction X. Based on the settings of the piston plug-in assembly 220 and the outer sleeve clamping assembly 210, in the first position, the outer sleeve clamping assembly 210 clamps the outer sleeve 610 to clamp the syringe 60, and then the outer sleeve clamping assembly 210 drives the syringe 60 to move to the second position. In the second position, the piston plug-in assembly 220 rises, and the piston plug-in assembly 220 separates the outer sleeve 610 from the piston rod 620. Then the outer sleeve clamping assembly 210 drives the outer sleeve 610 back to the first position. In the first position, the syringe 60 can be moved by the second transport Component 201 pours the sample in the first container 40 located at the first designated position 106 into the outer sleeve 610; thereafter, the outer sleeve clamping component 210 can drive the outer sleeve 610 containing the sample to move back to the second position, where the filter press operation is performed: the piston insertion and extraction component 220 inserts the piston rod 620 back into the outer sleeve 610 and presses the liquid in the sample in the syringe 60 with the filter element 70 into the second container 50; after the filter press is completed, the discarded syringe 60 can be discarded through the second transport component 201. In this way, the second transport component 201 can be conveniently cooperated to realize the automation of operations such as separating the syringe 60, pouring the sample, pressing the liquid in the sample in the syringe 60 with the filter element 70 into the second container 50 and discarding, which greatly reduces manual labor and avoids the situation that the sample that is not fully dissolved is difficult to filter out. The operations of pouring and filtering are respectively located at the first position and the second position along the first direction X, and the utilization of the space above the syringe 60 (that is, the space along the second direction Y) is converted into the utilization of the front space (that is, the space along the first direction X), which saves the upper space occupied by the pouring filter module 20 and greatly improves the space utilization rate. The pouring of the filter module 20 can leave enough operating space for the second transport component 201, which meets the degree of freedom required for the second transport component 201 to perform the pouring operation.

[0045] Combined with reference Figure 2 , Figure 3 and Figure 5, the outer sleeve clamping assembly 210 may include a first clamping claw 211, a first driving member 212, and a second driving member 213. The first driving member 212 and the first clamping claw 211 may be connected together through a first connecting member 214 to drive the first clamping claw 211 to switch between a retracted state and a released state. Understandably, the retracted state may be a state in which the first clamping claw 211 is clamping the outer sleeve 610, and the released state may be a state in which the first clamping claw 211 is releasing the outer sleeve 610. The second driving member 213 and the first clamping claw 211 may be connected together through a second connecting member 215 to drive the first clamping claw 211 to move between a first position and a second position along the first direction X. In this way, the outer sleeve clamping assembly 210 is moved between the first position and the second position along the first direction X by the second driving member 213, and the operations of pouring the sample and pressing the filter are performed at these two positions respectively. Compared with the device for performing the operations of pouring the sample and pressing the filter at the same position, the pouring and pressing filter module 20 in the present invention converts the utilization space above the syringe 60 into the utilization of the space in front, saving the upper space occupied by the pouring and pressing filter module 20, and greatly improving the space utilization rate. Among them, the number of the first clamping claws 211 can be two, and the end faces of the two first clamping claws 211 for clamping the syringe 60 can be recessed with arc segments or polygonal segments similar to the outer wall shape of the outer sleeve 610 in the direction away from each other, so as to facilitate the clamping of the outer sleeve 610. For example, in an exemplary embodiment of the present invention, the outer sleeve 610 is cylindrical, and the two first clamping claws 211 are recessed with arc segments in the direction away from each other relative to the end faces for clamping the syringe 60.

[0046] Further, in order to improve the stability of the first clamping claw 211 moving along the first direction X, and enhance the compactness of the first clamping claw 211, the first driving member 212 and the second driving member 213 to save the occupied space, the first clamping claw 211 and the first driving member 212 are connected through the first connecting member 214, and then the two are fixed to the second driving member 213 through the second connecting member 215. The second connecting member 215 can have a first connecting portion 2151 connected to the first driving member 212 and a second connecting portion 2152 connected to the second driving member 213, the first connecting portion 2151 can be connected to the first driving member 212 through fasteners such as screws or bolts, and the second connecting portion 2152 can be connected to the second driving member 213 through fasteners such as screws or bolts, and of course other connection methods are not excluded, such as welding or bonding, etc.

[0047] Combined with reference Figure 3 and Figure 5, the first connecting member 214 may have a first end 2141 and a second end 2142. The first end 2141 may be fixedly connected to the first clamping claw 211. The second end 2142 may be connected to the end of the first driving member 212 via a sliding connection structure 216, and the second end 2142 may slide between a third position and a fourth position along a third direction Z relative to the first driving member 212. The third direction Z may be perpendicular to the first direction X. When the first clamping claw 211 is in a retracted state, the second end 2142 may slide to the third position. When the first clamping claw 211 is in a released state, the second end 2142 may slide to the fourth position. Through the first end 2141 and the second end 2142 of the first connecting member 214, the first driving member 212 drives the first clamping claw 211 to switch between the retracted state and the released state to clamp or release the syringe 60, and the first clamping claw 211, the first connecting member 214 and the first driving member 212 are split structures and can be installed or disassembled, thereby facilitating replacement or maintenance.

[0048] Specifically, the sliding connection structure 216 may include two V-shaped protrusions 2161 formed by protruding from both sides of the second end 2142 toward the second direction Y and a groove 2162 formed by being recessed from the end surface of the first driving member 212 close to the first clamping claw 211 toward a direction away from the first clamping claw 211. Two V-shaped grooves 2162a may be recessed on both sides of the groove 2162 toward the second direction Y, and the V-shaped protrusions 2161 are limited in the V-shaped grooves 2162a to slide to slide and connect the first driving member 212 and the first connecting member 214. A first mounting hole 2141a may be provided on the first end 2141, and a mounting portion 2111 may be extended from the first clamping claw 211 toward the direction close to the first driving member 212, and a second mounting hole 2111a may be provided on the mounting portion 2111, and fasteners such as screws or bolts are sequentially passed through the first mounting hole 2141a and the second mounting hole 2111a to connect the first clamping claw 211 and the first connecting member 214. In this way, the first connecting member 214 can enhance the firmness of the connection between the first clamping claw 211 and the first driving member 212, and facilitate disassembly and assembly. It should be noted that the number of the first mounting holes 2141a can be at least one, the number of the second mounting holes 2111a can be at least one, and the number of the first mounting holes 2141a and the second mounting holes 2111a correspond to each other. Of course, it is not excluded that the protrusion is formed on the end surface of the first driving member 212 close to the first clamping claw 211, and the two V-shaped protrusions 2161 are formed by the protrusion protruding on both sides of the second direction Y, and the groove 2162 is concave on the second end 2142 in the direction away from the first driving member 212, and the groove 2162 can have two V-shaped grooves 2162a on both sides of the second direction Y, and the V-shaped protrusion 2161 is limited in the V-shaped groove 2162a to slide to slide and connect the first driving member 212 and the first connecting member 214. In addition, in the embodiment not shown in the figure, the combination of the V-shaped groove 2162a and the V-shaped protrusion 2161 can also be a combination of a square groove and a square protrusion or a combination of a polygonal groove and a polygonal protrusion, etc. The second end 2142 and the first driving member 212 include but are not limited to the above-mentioned connection methods, for example, they can also be connected by a slide rail connection and other connection methods. The first end 2141 and the first clamping claw 211 include but are not limited to the above-mentioned connection methods, for example, they can also be connected by welding or bonding and other connection methods.

[0049] Combined with reference Figure 1 , Figure 3 and Figure 5, the second driving member 213 may have a main body 2131 and a telescopic body 2132. The telescopic body 2132 may extend or retract relative to the main body 2131 along the first direction X, and the second connecting member 215 may be arranged on the telescopic body 2132. In this way, the second driving member 213 may drive the first clamping claw 211 to move between the first position and the second position through the telescopic body 2132 extending or retracting relative to the main body 2131 along the first direction X, and perform a dumping operation or a filter pressing operation at the two positions along the first direction X, thereby saving space for dumping the filter pressing module 20 in the second direction Y, leaving enough operating space for the second transport assembly 201, satisfying the degree of freedom required for the second transport assembly 201 to perform the dumping operation, and greatly improving the space utilization. For example, the second driving member 213 can be a slide cylinder, the main body 2131 can be a cylinder, the telescopic body 2132 can be a push rod and a slide, and the cylinder uses air pressure as a power source to make the piston push the push rod to drive the slide to move linearly, thereby realizing the outer sleeve clamping assembly 210 to move linearly along the first direction X.

[0050] Combined with reference Figure 2 and Figure 3 The piston plug-in assembly 220 may include a third driving member 221, a pushing member 222, and at least two clamping claws 223. The third driving member 221 and the at least two clamping claws 223 may be connected together through a third connecting member 224 to drive the clamping claws 223 to clamp the piston rod 620 or release the piston rod 620. The pushing member 222 may be disposed between the at least two clamping claws 223. The piston plug-in assembly 220 may clamp the piston rod 620 through the two clamping claws 223, and abut the end surface of the end of the piston rod 620 through the pushing member 222. When the piston plug-in assembly 220 performs the action of pulling the piston rod 620 out of the outer sleeve 610, the two clamping claws 223 clamp the piston rod 620 to drive it to rise. When the piston plug-in assembly 220 performs the action of inserting the piston rod 620 into the outer sleeve 610, the pushing piece 222 pushes the end face of the end of the piston rod 620 to drive it to descend. Both actions can be achieved only by the piston plug-in assembly 220, saving costs.

[0051] Furthermore, the end surfaces of the two clamping claws 223 for clamping the piston rod 620 can be recessed with arc segments or polygonal segments similar in shape to the outer wall of the piston rod 620 in a direction away from each other, so as to facilitate clamping the piston rod 620. The pushing member 222 can have a pushing portion 2221 for pushing the end of the piston rod 620 and a fixing portion 2222 extending from the pushing portion 2221 toward the third driving member 221. The fixing portion 2222 and the third driving member 221 can be fixed by fasteners such as screws or bolts, so that the pushing member 222 is detachable relative to the third driving member 221, so that the piston plug-in assembly 220 can be applied to different application scenarios, saving costs. The connection method between the third connecting member 224 and the third driving member 221 and the two clamping claws 223 can be the same as the connection method between the first connecting member 214 and the first clamping claw 211 and the first driving member 212, that is, the third connecting member 224 is fixedly connected to the two clamping claws 223 and is slidably connected to the third driving member 221, and the details are not repeated here.

[0052] Combined with reference Figure 2 , Figure 3 and Figure 4 , the piston plug-in assembly 220 may be connected to a lifting drive assembly 230. The lifting drive assembly 230 may include a fourth drive member 231, a screw rod 232, and a thrust plate 233. The fourth drive member 231 may drive the screw rod 232 to drive the piston plug-in assembly 220 and the thrust plate 233 to lift and lower along the second direction Y. The thrust plate 233 may be connected to the screw rod 232. When the screw rod 232 extends or retracts along the second direction Y relative to the fourth drive member 231, the thrust plate 233 may be driven to lift and lower along the second direction Y. The thrust plate 233 may be connected to the piston plug-in assembly 220. In the process that the screw rod 232 drives the thrust plate 233 to lift and lower along the second direction Y, the thrust plate 233 also drives the piston plug-in assembly 220 to lift and lower along the second direction Y, thereby realizing the automatic plugging and unplugging of the piston rod 620 and saving manual labor.

[0053] Again, refer to Figure 2 , Figure 3 and Figure 4A pressure detection member 240 may be provided between the thrust plate 233 and the end of the clamping claw 223, and the pressure detection member 240 may be used to detect the reaction force exerted on the piston rod 620. By providing the pressure detection member 240, when the piston rod 620 is inserted into the outer sleeve 610 (referred to as the insertion process for convenience of description), accurate feedback is provided for the pressure generated by the thrust plate 233, thereby ensuring the smoothness during the insertion process and preventing the outer sleeve 610 from being crushed due to excessive pressure. Specifically, the pressure detection member 240 may be a pressure sensor. When the piston rod 620 receives the reaction force, after the reaction force is transmitted to the pressure detection member 240, the pressure detection member 240 may display the pressure exerted by the thrust plate 233, and the power output by the fourth driving member 231 may be controlled by pressure feedback, thereby achieving the purpose of pressure controllability and ensuring that the force output during the insertion process is smooth (i.e., slow and controllable).

[0054] Combined with reference Figure 1 , Figure 3 and Figure 4 , the thrust plate 233 may have a plate body 2331 and a pushing body 2332. The plate body 2331 and the screw rod 232 may be connected together. The pushing body 2332 may extend from the plate body 2331 in a direction away from the screw rod 232. One end of the pressure detection member 240 may abut against the pushing body 2332, and the other end of the pressure detection member 240 may abut against the end of the clamping claw 223 through the connecting block 250. By providing the pushing body 2332, it is convenient for the pressure detection member 240 to be connected to the thrust plate 233, and by providing the connecting block 250, it is convenient for the pressure detection member 240 to be connected to the end of the clamping claw 223, thereby enhancing the firmness of the connection between the pressure detection member 240 and the thrust plate 233 and the end of the clamping claw 223.

[0055] Further, the dumping filter press module 20 also includes a fixed plate 260 arranged along the second direction Y, and the piston plug-in assembly 220 and the lifting drive assembly 230 are arranged on the fixed plate 260. Specifically, the fixed plate 260 has a first fixed surface 261 and a second fixed surface 262 along the first direction X, and a slide rail 263 can be arranged on the fixed plate 260, and a fourth driving member 231 and a screw rod 232 can be installed on the first fixed surface 261, and the plate body 2331 of the thrust plate 233 can be connected to the screw rod 232 and slide relative to the slide rail 263, and the piston plug-in assembly 220 can be installed on the second fixed surface 262 through the thrust body 2332. In this way, the piston plug-in assembly 220 and the lifting drive assembly 230 are arranged along the first direction X, which saves the space of the dumping filter press module 20 along the second direction Y, thereby greatly improving the space utilization.

[0056] Combined with reference Figure 2 , Figure 3 and Figure 6, a piston rod clamping assembly 270 may be provided between the outer sleeve clamping assembly 210 and the piston plug-in assembly 220. The piston rod clamping assembly 270 may have two second clamping claws 271. The two second clamping claws 271 may have a positioning and guiding state enclosed around the piston rod 620 and an open state with a predetermined angle between them. After the piston plug-in assembly 220 pulls the piston rod 620 out of the outer sleeve 610 by a predetermined height, the two second clamping claws 271 may be in a positioning and guiding state. When the piston plug-in assembly 220 inserts the piston rod 620 into the outer sleeve 610 to press out the liquid, the two second clamping claws 271 may be in an open state. When the two second clamping claws 271 of the piston rod clamping assembly 270 are enclosed around the piston rod 620, the piston rod 620 is positioned and guided, the piston rod 620 is prevented from tilting, and the piston rod 620 is ensured to be accurately inserted into the outer sleeve 610, thereby realizing accurate and automated operation.

[0057] Again, refer to Figure 2 , Figure 3 and Figure 6 , the two second clamping claws 271 may be respectively provided with a plurality of first teeth 2711 and a plurality of second teeth 2712. When the two second clamping claws 271 are in the positioning and guiding state, the first teeth 2711 and the second teeth 2712 are staggered and closed, and a positioning and guiding cavity 272 for the piston rod 620 to pass through is formed between the two second clamping claws 271. Usually, the piston rod 620 is a cross structure, and the cavity wall of the positioning and guiding cavity 272 formed by the two second clamping claws 271 through the staggered closing of the first teeth 2711 and the second teeth 2712 has a smooth effect, thereby having a good positioning and guiding effect on the piston rod 620 of the cross structure, ensuring that the piston rod 620 can be accurately inserted into the outer sleeve 610.

[0058] Specifically, the piston rod clamping assembly 270 may also include a fifth driving member 273, which drives the two second clamping claws 271 to rotate between a fifth position in an open state and a sixth position in a positioning guide state, thereby preventing the two second clamping claws 271 from blocking the piston insertion assembly 220 from performing a filter press operation.

[0059] Again, refer to Figures 1 to 3, the dumping filter press module 20 can also have a mounting plate 280. A filter element support plate 281 can be provided on one side of the mounting plate 280. The filter element support plate 281 can be used to support the filter element 70 connected to the bottom 611 of the outer sleeve 610. The bottom 611 of the outer sleeve 610 clamped by the outer sleeve clamping assembly 210 is connected with the filter element 70. By setting the filter element support plate 281 to support the filter element 70, shaking between the syringe 60 and the filter element 70 during the filter press process is avoided, resulting in poor filter press effect. Specifically, the filter element support plate 281 has a support groove 2811 with an opening away from the outer sleeve clamping assembly 210, and the bottom 611 of the support groove 2811 is provided with a through hole 2811a, which facilitates the placement of the filter element 70 in the support groove 2811. A notch may be provided on the side of the support groove 2811 away from the mounting plate 280, and a notch may also be provided on the side of the through hole 2811a away from the mounting plate 280, so that when the outer sleeve clamping assembly 210 clamps the syringe 60 connected with the filter element 70 and moves from the first position to the second position, it is convenient to place the filter element 70 in the support groove 2811.

[0060] Again, refer to Figure 2 and Figure 3 Before separating the piston rod 620 from the outer sleeve 610, the piston rod 620 can be pressed by the piston plug-in assembly 220 until the bottom 611 of the outer sleeve 610 is consistent with the installation height of the filter element 70, that is, the bottom 611 of the outer sleeve 610 and the filter element 70 are installed in place. At this time, the piston rod 620 is fully inserted into the outer sleeve 610, that is, when the piston rod 620 is subjected to a reaction force. In this way, it is ensured that there is no leakage at the connection between the syringe 60 and the filter element 70 during the filter pressing process, and the height of the piston rod 620 pulled out each time is consistent, ensuring the consistency of the filter pressing.

[0061] Again, refer to Figures 1 to 3 The dumping filter press module 20 may further include a linear guide assembly 290. The outer sleeve clamping assembly 210, the piston plugging assembly 220, the lifting drive assembly 230 and the piston rod clamping assembly 270 mentioned above may perform linear motion along the third direction Z on the linear guide assembly 290 through the mounting plate 280. In this way, the filter press process may be performed at different positions in the third direction Z through the linear guide assembly 290.

[0062] Again, refer to Figures 1 to 3, the dumping filter press module 20 can also have a second container loading assembly 202. The second container loading assembly 202 can have an upper transport member 2021 and a lower material receiving member 2022. The lower material receiving member 2022 is movable between the material receiving position and the loading position along the second direction Y. The upper transport member 2021 can transport the second container 50 to the material receiving position, and the second container 50 can be transported from the material receiving position to the loading position through the lower material receiving member 2022. In this way, the automatic loading of the second container 50 is realized, thereby improving efficiency and reducing labor costs. Specifically, the upper transport member 2021 may include a conveyor belt (not shown in the figure), and the operator can place the deep hole plate or material box equipped with the second container 50 on the conveyor belt, and then transport it to the material receiving position through the conveyor belt. The lower transport member may include a lifting assembly (not shown in the figure), which can be moved between the material receiving position and the loading position through the lifting assembly. When the deep hole plate or material box with the second container 50 is transported to the loading position, the second container 50 can be opened, and the opened second containers 50 are transported one by one for loading. Of course, it is not excluded that the second container 50 is already opened during loading.

[0063] Combined with reference Figure 1 , Figure 7 and Figure 8 , the front-end processing module 10 may include a first placement area 101, a liquid adding component 100 and a first transport component 102. The first placement area 101 may be used to place a plurality of first containers 40. The liquid adding component 100 may be used to add liquid to the first container 40. The first transport component 102 may transfer the first container 40 located in the first placement area 101 to the liquid adding component 100 or transfer the first container 40 located on the liquid adding component 100 to the first designated position 106. In this way, automated pre-processing operations are realized, the time and energy consumption of operators is reduced, and efficiency is improved, thereby avoiding the phenomenon that operators are physically exhausted due to high-intensity labor, causing damage to experimental equipment, and even safety hazards.

[0064] Combined with reference Figures 7 to 10The liquid adding assembly 100 may include a loading turntable 110 and a liquid adding structure 120. The loading turntable 110 may be provided with a plurality of racks 111 for fixing the first container 40, and the loading turntable 110 may be rotatably arranged around the central axis so that each rack 111 can be rotatable between a liquid adding position and a non-liquid adding position. The liquid adding structure 120 may be arranged above the loading turntable 110, and the liquid adding structure 120 may inject the solution into the first container 40 when the rack 111 rotates to the liquid adding position. In this way, the loading turntable 110 is arranged below the liquid adding structure 120, and with the rotation setting of the loading turntable 110 around the central axis, the first container 40 placed in the placement rack 111 on the loading turntable 110 can be rotated between the liquid adding position and the non-liquid adding position. Based on the fact that the liquid adding structure 120 has sufficient movement space, the distance between the first containers 40 is shortened, and the space below the liquid adding structure 120 is effectively utilized, thereby improving the space utilization rate, making the entire device more compact and convenient to use in a small space.

[0065] Furthermore, the feeding turntable 110 is connected to a dividing motor assembly 130, specifically, see Fig. 9 , the indexing motor assembly 130 may include a driving motor 131, a speed reducer 132 and an output shaft flange 133. The driving motor 131 may be connected to the speed reducer 132, and the output shaft of the speed reducer 132 may be connected to the output shaft flange 133 through a keyway, and the output shaft flange 133 may be driven to rotate by the driving motor 131. The feeding turntable 110 may be connected to the output shaft flange 133 through fasteners such as bolts or screws, so that the feeding turntable 110 may rotate around the central axis through the drive of the driving motor 131. Here, the driving motor 131 may adopt a common indexing motor, and the indexing motor is a precision motor, and its structure mainly includes two parts, a stator and a rotor, the stator is fixed on the frame, and the rotor is installed on the output shaft, and there is a small gap between the stator and the rotor, and this gap is the basic unit of indexing. Since the indexing motor is a common motor, it will not be described in detail here. Based on the use of the indexing motor assembly 130, each placement rack 111 can be accurately rotated between the liquid adding position and the non-liquid adding position.

[0066] See also Fig. 9The placement rack 111 can be generally in the shape of a column with an opening, so as to facilitate the placement or taking of the first container 40, and to make the first container 40 have a high stability, so as to avoid the first container 40 from shaking when the loading turntable 110 rotates around the central axis, thereby causing the liquid in the first container 40 to splash out, or even causing the first container 40 to be unable to be fully aligned with the liquid adding structure 120 when the placement rack 111 rotates to the liquid adding position. The sizes of the multiple placement racks 111 can be different, so as to be suitable for placing first containers 40 of various sizes, so that the liquid adding assembly 100 can be applied to a variety of scenarios, including but not limited to experimental scenarios.

[0067] See again Fig. 9 , the liquid adding component 100 may further include an anti-drip component 140. The anti-drip component 140 may be switched between a liquid receiving position and an avoidance position, and when the anti-drip component 140 is switched to the liquid receiving position, it may be located between the liquid adding structure 120 and the loading turntable 110 to collect the solution dripping from the liquid adding structure 120. In this way, the anti-drip component 140 collects the liquid dripping from the liquid adding structure 120 at the liquid receiving position to prevent cross contamination caused by liquid splashing.

[0068] The drip-proof liquid component 140 may include a first drip-proof liquid structure 141 and a second drip-proof liquid structure 142. When the drip-proof liquid component 140 is switched to the liquid receiving position, the first drip-proof liquid structure 141 and the second drip-proof liquid structure 142 may be closed together and located below the liquid adding structure 120. When the drip-proof liquid component 140 is switched to the avoidance position, the first drip-proof liquid structure 141 and the second drip-proof liquid structure 142 may be unfolded together and located on both sides of the liquid adding structure 120, respectively. The liquid adding structure 120 is connected to the liquid by the first drip-proof liquid structure 141 and the second drip-proof liquid structure 142, thereby effectively preventing cross contamination, and the speed of switching between the liquid receiving position and the avoidance position is fast, thereby improving the efficiency of movement.

[0069] The first anti-drip liquid structure 141 is connected to the first driving structure 143 so that it can move along the third direction Z or the direction opposite to the third direction Z under the drive of the first driving structure 143, and the second anti-drip liquid structure 142 is connected to the second driving structure 144 so that it can move along the third direction Z or the direction opposite to the third direction Z under the drive of the second driving structure 144, so as to realize that the first anti-drip liquid structure 141 and the second anti-drip liquid structure 142 are mutually closed or mutually expanded. Specifically, the first driving structure 143 drives the first anti-drip liquid structure 141 to move along the third direction Z, and the second driving structure 144 drives the second anti-drip liquid structure 142 to move along the direction opposite to the third direction Z, until the first anti-drip liquid structure 141 and the second anti-drip liquid structure 142 are mutually closed and located below the liquid adding structure 120, at which time, the anti-drip liquid component 140 is switched to the liquid receiving position. The first driving structure 143 drives the first anti-drip structure 141 to move in the direction opposite to the third direction Z, and the second driving structure 144 drives the second anti-drip structure 142 to move in the third direction Z, until the first anti-drip structure 141 and the second anti-drip structure 142 are deployed with each other and are respectively located on both sides of the liquid adding structure 120. At this time, the anti-drip assembly 140 switches to the avoidance position. In this way, cross contamination is effectively prevented, and the efficiency of the movement of the first anti-drip structure 141 and the second anti-drip structure 142 is improved. Among them, the first driving structure 143 and the second driving structure 144 can be telescopic cylinders driven by air pressure, and of course it is not ruled out that the first driving structure 143 and the second driving structure 144 are motors, etc.

[0070] The first anti-drip structure 141 and the second anti-drip structure 142 may both include a liquid receiving member 145. The liquid receiving member 145 may have a liquid receiving groove 1451 on the surface facing away from the loading turntable 110 and facing the loading turntable 110. Liquid is received through the liquid receiving groove 1451, thereby preventing the received liquid from directly flowing out of the liquid receiving member 145, causing cross contamination.

[0071] Combined with reference Fig. 9 and Fig.10 , the liquid adding structure 120 may include an assembly plate 121 and at least one liquid adding needle 122. The liquid adding needle 122 may be installed through the assembly plate 121, and when the placement rack 111 rotates to the liquid adding position, the projection of the liquid adding needle 122 on the loading turntable 110 may fall into the first container 40 fixed to the placement rack 111. In this way, the liquid adding needle 122 is installed through the assembly plate 121, which enhances the stability of the liquid adding needle 122 and prevents the liquid adding needle 122 from shaking during liquid addition, and the liquid flows to the outside of the first container 40, causing cross contamination.

[0072] The assembly plate 121 can be configured as a semi-enclosed body 1211 with a notch, and at least one liquid adding needle 122 can be arranged and distributed along the semi-enclosed body 1211. In this way, the first container 40 in the placement rack 111 on the loading turntable 110 rotating around the central axis can be added with liquid. Compared with the situation where the liquid adding needle 122 is distributed along a straight line on the assembly plate 121, the arrangement is compact and space is saved. Since the liquid adding needle 122 is compactly arranged, the drip-proof assembly 140 facilitates the liquid connection of all the liquid adding needles 122 to prevent the liquid from dripping when the liquid adding needle 122 moves, causing cross contamination. Specifically, 5 liquid adding needles 122 can be provided, and they are arranged at intervals along the circumference of the semi-enclosed body 121. Of course, it is not ruled out that 3, 6 or 8 liquid adding needles are provided.

[0073] The assembly plate 121 is connected to a third driving structure 123 so that it can move between the seventh position and the eighth position along the second direction Y under the drive of the third driving structure 123. When the assembly plate 121 is switched to the seventh position, the liquid adding needle 122 can be located in the first container 40. When the assembly plate 121 is switched to the eighth position, the liquid adding needle 122 can be located outside the first container 40. When the first container 40 on the placement rack 111 is located at the liquid adding position, the assembly plate 121 can be switched to the seventh position, and the liquid adding needle 122 can be located in the first container 40 for liquid adding, which effectively avoids the splashing of dripping liquid and causes cross contamination. When the assembly plate 121 is switched to the eighth position, the anti-drip assembly 140 can be located at the liquid receiving position, and the liquid adding needle 122 can be located in the liquid receiving groove 1451 of the first anti-drip structure 141 and the second anti-drip structure 142, thereby avoiding the liquid adding needle 122 dripping and causing cross contamination. The assembly plate 121 can be mounted on the third driving structure 123 by fasteners such as bolts or screws. The third driving structure 123 may be a lifting cylinder, but it is not excluded that the third driving structure 123 may be a lifting motor or the like.

[0074] The liquid adding assembly 100 may further include an origin detector 150 . The origin detector 150 may determine the origin of the loading turntable 110 by sensing the position of a detection point 112 located on the loading turntable 110 . Specifically, the detection point 112 can be a groove portion that is recessed toward the liquid adding structure 120 and on the wall surface of the loading turntable 110 away from the liquid adding structure 120. The origin detector 150 can be directly disposed on a frame (not shown) for placing the liquid adding component 100 or indirectly disposed on the frame. The detection end surface 151 of the origin detector 150 faces the wall surface of the loading turntable 110 away from the liquid adding structure 120. The origin detector 150 can output a detection signal to the controller when identifying the groove portion. The controller can adopt a commonly used programmable logic controller. The controller can determine the origin of the loading turntable 110 and the rotation angle of the loading turntable 110 based on the detection signal fed back by the origin detector 150, so as to ensure that the liquid adding needle 122 is located directly above the first container 40 when adding liquid, thereby realizing the precise rotation of each placement rack 111 between the liquid adding position and the non-liquid adding position.

[0075] Further, the placement rack 111 can be connected to the feeding turntable 110 through a quick-change assembly 160. The quick-change assembly 160 may include an insertion hole 161, an elastic latch 162 and a locking groove 163. The insertion hole 161 may be provided on the feeding turntable 110. The elastic latch 162 may be provided in the insertion hole 161. The locking groove 163 may be provided on the placement rack 111 and along the circumference of the placement rack 111. The elastic latch 162 may be configured to latch with the locking groove 163 in a normal state and to disengage from the locking groove 163 when subjected to an external force. In this way, the feeding turntable 110 is prevented from rotating the placement rack 111 out during rotation, and the feeding turntable 110 and the placement rack 111 can be quickly disassembled and assembled through the quick-change assembly 160.

[0076] Specifically, an insertion column 1111 extends from the bottom of the placement rack 111, and an assembly hole 164 is provided on the loading turntable 110, and the assembly hole 164 penetrates from the wall of the loading turntable 110 toward the liquid adding structure 120 to the wall away from the liquid adding structure 120. The insertion hole 161 extends from the outer side surface of the loading turntable 110 along the radial direction of the loading turntable 110 inward to the assembly hole 164, and the elastic latch 162 is provided in the insertion hole 161, and the elastic latch 162 can be a plunger with a ball head marble at one end. The locking groove 163 can be provided on the insertion column 1111 extending from the bottom of the placement rack 111. In this way, when inserting the insertion column 1111 at the bottom of the placement rack 111 into the assembly hole 164, when the outer peripheral surface of the insertion column 1111 abuts against the ball of the plunger, the plunger is compressed and the ball is retracted into the insertion hole 161. When the insertion column 1111 is further inserted down to the locking groove 163 and opposite to the ball, the plunger rebounds to a normal state under the action of the elastic restoring force, and the ball extends out and engages with the locking groove 163, thereby completing the installation of the placement rack 111. When it is necessary to remove the placement rack 111 from the loading turntable 110, an upward force can be applied to move the insertion column 1111 upward. During the upward movement of the insertion column 1111, the ball gradually disengages from the locking groove 163, thereby completing the rapid disassembly and assembly of the placement rack 111.

[0077] Furthermore, since first containers 40 of different sizes can be placed, corresponding placement racks 111 are installed according to the first containers 40 of the required size or shape in the scene, without replacing the entire liquid adding assembly 100, thereby saving costs.

[0078] First containers 40 of various sizes can be arranged on the loading turntable 110 at the same time to shorten the gaps between the liquid containers and save space. The first containers 40 can cover the liquid receiving area, so that multiple first containers 40 can be filled with liquid at one time, which improves efficiency, reduces the movement of the filling needle 122, and greatly reduces the risk of cross contamination.

[0079] Again, refer to Figure 1 , Figure 7 and Figure 8, the front-end processing module 10 may also include a shaking component 103, a centrifugal component 104 and a third placement area 105. The shaking component 103 may have a second placement area 1031 for placing the first container 40 to allow the liquid in the first container 40 to be evenly mixed. It should be noted that the second placement area 1031 of the shaking component 103 can be used to place multiple first containers 40, and the first container 40 after adding liquid can be heated while shaking and shaking to accelerate the mixing of solids and liquids in the first container 40. The shaking component 103 can be a vortex instrument, etc. The centrifugal component 104 can be arranged below the shaking component 103 to centrifuge the mixed liquid in the first container 40. Specifically, the centrifugal component 104 has a centrifugal feed port 1041, and the first container 40 after shaking is transported to the centrifugal component 104 through the centrifugal feed port 1041 for centrifugation. It can be understood that centrifuging the first container 40 can quickly separate the components that need to be processed in the sample, or reduce other impurities in the sample. The third placement area 105 can be used to place the centrifuged first container 40. In this way, the front-end processing module 10 realizes a fully automated pre-processing operation, enhances the continuity of the operation, and has a high degree of integration, saving space.

[0080] The first transport assembly 102 may include a first transport member 1021 and a second transport member 1022. The first transport member 1021 is movable between the first placement area 101, the liquid adding assembly 100, and the second placement area 1031. The second transport member 1022 is movable between the second placement area 1031, the centrifugal assembly 104, the third placement area 105, and the first designated position 106. In this way, the first transport member 1021 and the second transport member 1022 can move in multiple areas to transport the first container 40, achieving full automation and saving manpower.

[0081] The front-end processing module 10 may further include a code scanning component (not shown) for scanning the first container 40. The code scanning component may be installed on the first transport member 1021, and the code scanning operation may be performed during the transport of the first container 40, thereby saving space and improving efficiency.

[0082] Combined with reference Figure 1 and Figure 2 , the back-end processing module 30 may include an annular conveyor line 301, a switch cover assembly, a coding assembly (not shown in the figure) and a material discharge assembly (not shown in the figure). The annular conveyor line 301 may have a switch cover station 302, a coding station 303 and a material discharge station 304 which are arranged one by one corresponding to the switch cover assembly, the coding assembly and the material discharge assembly. The annular conveyor line 301 may also have a liquid transfer station 305, and the second container 50 can be moved between the liquid transfer station 305 and the second position through the liquid transfer assembly. In this way, the entire sample processing device 1 is fully automated, saving manpower.

[0083] Combined with reference Figure 2 , Fig.11 and Fig.12 , the switch cover assembly may include a bottle cap loading assembly 300 and a mechanical gripper (not shown in the figure). The mechanical gripper may be used to transport the second container 50 from the second container loading assembly 202 to the annular conveyor line 301, take the bottle cap provided by the bottle cap loading assembly 300 and screw it on the second container 50 that receives the sample after pressure filtration, and transport the second container 50 after closing the cover to the unloading assembly. The bottle cap loading assembly 300 may include a base 310, a material rack 320, an anti-blocking member 330, and a material taking assembly 340. The material rack 320 may be arranged on the base 310, and the material rack 320 may have a storage bin 321 for storing bottle caps in a stacked manner. The storage bin 321 may have a loading port 3211 and a discharging port 3212. The anti-blocking member 330 may be pressed from the loading port 3211 to the surface of the bottle cap located at the top in the storage bin 321. The material taking assembly 340 may be located below the material rack 320. The picking assembly 340 can pick up the bottle cap located at the bottom of the storage bin 321 from the discharge port 3212. In this way, on the one hand, based on the storage bin 321 for storing bottle caps in a stacked manner on the material rack 320, the picking assembly 340 picks up the bottle caps from the bottom of the material rack 320, which saves space and thus increases the operating space; on the other hand, since the anti-blocking member 330 is added to the surface of the top bottle cap in the storage bin 321, the bottle cap can fall smoothly under the pressure of the anti-blocking member 330. After the picking assembly 340 picks up the bottle cap located at the bottom of the storage bin 321, it is ensured that the remaining bottle caps will not be stuck in the middle of the storage bin 321 of the material rack 320, so that the next bottle cap can be in place in time, which not only simplifies the bottle cap feeding process and improves the bottle cap feeding efficiency, but also reduces the high-decibel noise of the feeding process.

[0084] Furthermore, the weight of the anti-blocking member 330 must be greater than the weight of the bottle cap so that the bottle cap can fall smoothly under the pressure of the anti-blocking member 330. In this way, the anti-blocking member 330 can be a counterweight block, such as an iron block, aluminum block or other metal block, which is not only low-cost but also convenient for production and processing.

[0085] See also Fig.11, the material rack 320 may include a material rack body 322. The discharge port 3212 may be arranged at the lower end of the material rack body 322 and suspended relative to the base 310. The material picking assembly 340 may be arranged beside the discharge port 3212. The discharge port 3212 is arranged at the lower end of the material rack body 322, which can facilitate the material picking assembly 340 to clamp the bottle cap, and facilitate the next bottle cap to fall to the discharge port 3212 under the action of gravity, thereby improving the bottle cap feeding efficiency. It should be noted that the discharge port 3212 corresponds to the side of the material picking assembly 340 used to clamp the bottle cap. The height of the discharge port 3212 is consistent with the height of a bottle cap, thereby improving the accuracy of the material picking assembly 340 to clamp the bottle cap, and avoiding the phenomenon that the discharge port 3212 is too high, resulting in the material picking assembly 340 When clamping the bottom bottle cap, the bottle cap above it falls and deviates or is taken out of the discharge port 3212.

[0086] Combined with reference Fig.11 and Fig.12 , the material rack 320 may further include a fixing member 323. The material rack body 322 may be fixed to the base 310 by the fixing member 323. Compared with directly fixing the material rack body 322 to the base 310, fixing the material rack body 322 to the base 310 by the fixing member 323 occupies less space, thereby saving space and ensuring the stability of the material rack body 322. The fixing member 323 has a certain length in the direction away from the material rack body 322, thereby playing the role of a reinforcing rib, ensuring that the fulcrum at the bottom of the material rack body 322 can be longer, lowering the center of gravity of the material rack body 322, and thus improving the stability of the material rack body 322.

[0087] The base 310 may include a main body 311 and a rotating part 312. The rotating part 312 may be rotatably connected to the main body 311. Specifically, the base 310 may rotate the rotating part 312 relative to the main body 311 by manual operation, a motor, or an air bearing. The material rack 320 is fixedly connected to the rotating part 312 so as to be rotatable relative to the main body 311. The rotating part 312 drives the material rack 320 to rotate relative to the main body 311, thereby facilitating the material rack 320 to quickly and accurately reach the material picking position corresponding to the material picking assembly 340. In order to correspond to the cylindrical arrangement of multiple groups of material racks 320, the base 310 used to set the material rack 320 may be cylindrical. Compared with the linear base 310, the cylindrical base 310 occupies less space and saves space.

[0088] A blocking member 3111 may be provided on the main body 311 around the material rack 320. The blocking member 3111 may have an opening (not shown in the figure). When the material rack 320 rotates to the point where the discharge port 3212 is opposite to the opening, the material taking assembly 340 may clamp the bottle cap located at the bottom of the storage bin 321 through the opening. The blocking member 3111 is provided to limit the bottle cap located at the discharge port 3212, thereby preventing the bottle cap located at the discharge port 3212 from flying out. Specifically, the opening can only correspond to one group of material racks 320, so as to facilitate accurate correspondence with the material taking assembly 340, thereby preventing the opening from being too large, resulting in the blocking member 3111 being unable to limit the bottle cap located at the discharge port 3212.

[0089] The material rack 320 may be provided with a plurality of observation ports 324 at intervals along the loading direction. Through the observation ports 324, the use of the bottle caps in the storage bin 321 can be observed, so that the material can be loaded or replaced in time with other material racks 320, and whether the bottle caps stacked in the storage bin 321 are stuck or staggered can be observed through the observation ports 324, so as to facilitate timely processing and thereby improve the efficiency of loading the bottle caps. Specifically, the observation port 324 may be provided with a plurality of runway-shaped holes along the loading direction, each hole being provided at the stacking position of the bottle caps, so as to facilitate the observation of the bottle caps in the storage bin 321. The observation port 324 may also be a slender strip hole along the loading direction to facilitate processing, while preventing the observation port 324 from affecting the smoothness of the bottle caps falling. Of course, the observation port 324 may also be other shapes, but it is necessary to meet the requirements of ensuring the strength of the main body of the material rack 320 and preventing the bottle caps from running out of the observation port 324.

[0090] The material taking assembly 340 may include a clamp 341, a first driver 342, a second driver 343 and a third driver 344. The first driver 342 may be connected to the clamp 341 to drive the clamp 341 to close and clamp the bottle cap or to drive the clamp 341 to open and release the bottle cap. The second driver 343 may be connected to the first driver 342 to drive the clamp 341 to move between the away position and the clamping position through the first driver 342. The third driver 344 may be connected to the second driver 343 to drive the clamp 341 to move between the away position and the disengagement position in the plane through which the second driver 343 and the first driver 342 drive the clamp 341 to move. Wherein, when the clamp 341 is in the away position, it can be away from the discharge port 3212. When the clamp 341 moves to the clamping position, it can be located directly below the discharge port 3212. When the clamp 341 rotates to the disengagement position, it can be farther away from the discharge port 3212 than the away position. The material taking assembly 340 can accurately clamp the bottle caps for transportation, thereby preventing the bottle caps from getting stuck when they are separated from the material outlet 3212. Compared with a conveyor belt, the material taking assembly 340 occupies less space, thereby saving space.

[0091] The material taking component 340 may further include a bottle cap adapter 345. The bottle cap adapter 345 may be arranged beside the third driver 344. The bottle cap adapter 345 is connected to the fourth driver 346 so that it can move between the receiving position and the transfer position along the second direction Y driven by the fourth driver 346. When the clamp 341 rotates to the disengaged position, the bottle cap adapter 345 may move to the receiving position to receive the bottle cap that is loosened from the clamp 341. By moving the bottle cap adapter 345 along the second direction Y to transport the bottle cap, the space in the second direction Y is more effectively utilized, so that it is suitable for use in an environment with limited space. The receiving position may be a position where the bottle cap adapter 345 is located below the bottle cap clamped by the clamp 341, and the transfer position may be a position where the bottle cap adapter 345 transfers the bottle cap to the mechanical clamp.

[0092] Combined with reference Figures 1 to 12 The working process of the sample processing device 1 is described in detail below:

[0093] The first container 40 is loaded to the first placement area 101 by an operator or a manipulator, and the first transport member 1021 can grab the first container 40 placed in the first placement area 101, and scan the grabbed first container 40 through the code scanning component. Then the first container 40 is transported to the placement rack 111 of the liquid adding component 100, and the loading turntable 110 can rotate the placement rack 111 to the liquid adding position, and the first anti-drip structure 141 and the second anti-drip structure 142 are unfolded from the bottom of the liquid adding structure 120 to the two sides of the liquid adding structure 120. The assembly plate 121 switches from the eighth position to the seventh position, and the liquid adding needle 122 moves from the outside of the first container 40 to the inside of the first container 40, and starts to add liquid to the first container 40. After the liquid addition is completed, the assembly plate 121 switches from the seventh position to the eighth position, and the first anti-drip structure 141 and the second anti-drip structure 142 are closed together and moved from both sides of the liquid addition structure 120 to the bottom of the liquid addition structure 120. The loading turntable 110 rotates to the non-liquid addition position, and the first container 40 after liquid addition is transported to the second placement area 1031, and the first container 40 after liquid addition is shaken and heated to accelerate the mixing of the solid and liquid in the first container 40. After the shaking is completed, the first container 40 after shaking is transported to the centrifugal assembly 104 through the centrifugal feed port 1041 by the second transporting member 1022 for centrifugation, and the first container 40 after centrifugation is placed on the third placement area 105, and then the first container 40 after centrifugation located in the third placement area 105 is transported to the first designated position 106. At the same time, the syringe 60 with the filter 70 can be transported to the filter support plate 281 or to the first position where the outer tube clamping assembly 210 can clamp the syringe 60 through the second transport assembly 201. Afterwards, the outer tube clamping assembly 210 clamps and drives the syringe 60 to move to the second position. In the second position, the piston plug-in assembly 220 presses the piston rod 620 until the bottom 611 of the outer tube 610 is consistent with the installation height of the filter 70. The piston plug-in assembly 220 rises, and when the piston rod 620 is raised to a certain height, the two second clamping claws 271 of the piston rod clamping assembly 270 form a positioning guide cavity 272 between each other, thereby ensuring that the piston plug-in assembly 220 stably separates the outer tube 610 from the piston rod 620. Subsequently, the outer tube clamping assembly 210 drives the outer tube 610 to move to the first position, and the sample in the first container 40 located at the first designated position 106 is transported and poured into the outer tube 610 through the second transport assembly 201. At the same time, the upper transport member 2021 of the second container loading assembly 202 can transport the second container 50 to the material receiving position, and the second container 50 can be transported from the material receiving position to the material loading position through the lower material receiving member 2022, and then the second container 50 is transported to the annular conveyor line 301 by the mechanical gripper. At the liquid transfer station 305, the second container 50 is transported to the position for receiving the filter press sample by the liquid transfer assembly.Afterwards, the outer sleeve clamping assembly 210 can drive the outer sleeve 610 containing the sample to move back to the second position. At the second position, the filter pressing operation is performed: the piston plug-in assembly 220 inserts the piston rod 620 back into the outer sleeve 610 and presses the liquid in the sample in the syringe 60 with the filter element 70 into the second container 50; after the filter pressing is completed, the discarded syringe 60 can be discarded through the second transport assembly 201. At the liquid transfer station 305, the second container 50 is transported to the circular conveyor line 301 by the liquid transfer assembly. When the second container 50 passes the cover opening and closing station 302 on the circular conveyor line 301, the cover of the second container 50 is closed by the cover opening and closing assembly. When it reaches the coding station 303, the coding operation is performed on the second container 50 and the bottle cap. Finally, it reaches the material discharge station 304, and the second container 50 is transported to the deep well plate or the material box to complete the material discharge, and then the above-mentioned overall operation is repeated.
