Technical Field

[0001] This application relates to the technical field of sample preparation, and particularly relates to a sample preparation workstation. Background Art

[0002] In laboratories in many fields such as scientific research, medical treatment, and chemical engineering, sample preparation is usually required. For example, in the production of batteries such as lithium batteries and sodium batteries, laboratories sometimes need to prepare samples of electrolytes and passivators.

[0003] Traditional sample preparation mainly relies on manual operation, but the manual operation efficiency is relatively low; in addition, in the case of preparing a large number of samples, the labor intensity of the operator is large and the overall preparation speed is slow; on the other hand, it is difficult to guarantee the accuracy of manual operation, which may affect the reliability and repeatability of experimental results.

[0004] To solve the problem of manual sample preparation, some sample preparation devices have emerged on the market; however, the sample preparation devices in related technologies are usually large in volume and occupy a large amount of laboratory space. Utility Model Content

[0005] The main purpose of this application is to propose a sample preparation workstation to help reduce the occupied space.

[0006] To achieve the above object, the sample preparation workstation proposed in this application includes a bracket, a moving module, a solid addition device, a liquid addition device, and a metering system. The moving module is installed on the bracket; the solid addition device is installed on the moving module, and the moving module is used to move the solid addition device towards the sample container; the solid addition device has a solid output channel for conveying solid materials to the sample container; the liquid addition device is installed on the moving module, and the moving module is used to move the liquid addition device towards the sample container; the liquid addition device has a liquid output channel for conveying liquid materials to the sample container; the metering system is connected to at least one of the sample container, the solid addition device, and the liquid addition device; the metering system is used to correspondingly measure at least one of the total mass of the materials added to the sample container, the output amount of the solid materials output from the solid output channel, and the output amount of the liquid materials output from the liquid output channel.

[0007] When the sample preparation workstation provided in this application is in use, the solid addition device and the liquid addition device can be respectively moved through the moving module, so that they can move to the sample container quickly and add the required solid materials and liquid materials, and the metering of the feeding can be completed through the metering system, which helps to reduce the transfer of the sample container and materials and reduces the overall operation time. In addition, the solid addition device and the liquid addition device are respectively installed on the moving module, which helps to reduce the occupied space of the sample preparation workstation compared with independently equipped solid addition devices and liquid addition devices.

[0008] In one implementation, the bracket includes a top connection frame and at least three columns. The top parts of the columns are respectively fixedly connected to the top connection frame, and the columns are arranged at intervals along the direction surrounding the top connection frame. The top connection frame and the columns enclose an accommodation space; the moving module is connected to the top connection frame, and at least part of the moving module, at least part of the solid addition device, and at least part of the liquid addition device are respectively arranged in the accommodation space, and the sample container is used to be arranged in the accommodation space.

[0009] At this time, the columns are arranged at intervals along the direction surrounding the top connection frame, and the columns are fixedly connected to the top connection frame, so that the structural strength of the bracket can be improved, and the shaking caused by the movement of the moving module can be suppressed. In addition, at least part of the moving module, at least part of the solid addition device, and at least part of the liquid addition device are respectively arranged in the accommodation space, and the sample container is used to be arranged in the accommodation space, which is beneficial to further reduce the occupied space of the sample preparation workstation.

[0010] In one implementation, the bracket further includes a bottom connection frame, and the bottom parts of the columns are respectively fixedly connected to the bottom connection frame.

[0011] At this time, the bottom connection frame can further improve the structural strength of the bracket, so that the shaking caused by the movement of the moving module can be further suppressed. In addition, the bottom connection frame can increase the bottom support area of the bracket, thereby reducing the collision damage of the overall weight of the sample preparation workstation to the test bench.

[0012] In one implementation, the moving module includes a first translation mechanism, a second translation mechanism and a lifting mechanism. The first translation mechanism is connected to the bracket, the second translation mechanism is connected to the first translation mechanism, and the lifting mechanism is connected to the second translation mechanism; the first translation mechanism is used to move the second translation mechanism along the first horizontal direction, the second translation mechanism is used to move the lifting mechanism along the second horizontal direction, and there is an included angle between the second horizontal direction and the first horizontal direction; the solid addition device and the liquid addition device are respectively installed on the lifting mechanism, and the lifting mechanism is respectively used to lift the solid addition device and the liquid addition device.

[0013] At this time, the first translation mechanism, the second translation mechanism and the lifting mechanism of the moving module can quickly move the solid addition device and the liquid addition device to the corresponding sample containers, reducing the overall operation time.

[0014] In one implementation, the second translation mechanism includes a lead screw and a guide rod. The lead screw and the guide rod are respectively arranged to extend along the horizontal direction, and the extending direction of the lead screw is parallel to the extending direction of the guide rod. The lifting mechanism includes a threaded connection block and a guiding connection block, and the threaded connection block is fixedly connected to the guiding connection block. The threaded connection block is provided with a threaded through hole, and the threaded through hole is in threaded connection with the lead screw. The guiding connection block is provided with a guiding through hole, and the guide rod passes through the guiding through hole, and the outer wall of the guide rod abuts against the hole wall of the guiding through hole. The thickness direction of the threaded connection block and the thickness direction of the guiding connection block are respectively parallel to the extending direction of the guide rod, and the thickness of the threaded connection block is less than the thickness of the guiding connection block.

[0015] At this time, the second translation mechanism can achieve translation through the lead screw, the guide rod, the threaded connection block and the guiding connection block. In addition, the thickness of the threaded connection block is less than the thickness of the guiding connection block, so that the guiding stability can be improved through the guide rod and the thicker guiding connection block, and the processing difficulty of the threaded through hole can be reduced through the thinner threaded connection block.

[0016] In one implementation, the sample preparation workstation further includes a material loading rack, and the material loading rack is at least used for loading solid materials. The material loading rack is installed on the moving module, and the moving module is used to move the material loading rack towards the sample container. The solid adding device is relatively fixed to the material loading rack, and the solid output channel is used to convey the solid materials from the material loading rack to the sample container.

[0017] At this time, the material loading rack can at least load a certain amount of solid materials, so that solid materials can be continuously provided for different sample containers, which is beneficial to realizing the continuous operation of multiple sample preparation operations.

[0018] In one implementation, the lifting mechanism of the moving module includes a lifting guide and a lifting connecting piece. The lifting guide is arranged to extend along the direction of gravity. The lifting connecting piece is connected to the lifting guide, and the lifting connecting piece is used to lift along the lifting guide. The material loading rack is provided with a connecting through hole, and the lifting guide passes through the connecting through hole. The lifting connecting piece is arranged in the connecting through hole, and the lifting connecting piece is connected to the hole wall of the connecting through hole.

[0019] At this time, the lifting guide passes through the connecting through hole of the material loading rack, so that the material loading rack has a mass distribution around the lifting guide, which is beneficial to reducing the deflection moment acting on the lifting guide by the material loading rack, and is beneficial to avoiding jamming and wear between the lifting connecting piece and the lifting guide.

[0020] In one implementation, the material loading rack is provided with a material loading groove, and the material loading groove is arranged to extend along the direction surrounding the connecting through hole.

[0021] At this time, the material loading groove of the material loading rack extends along the direction surrounding the connecting through hole, which is beneficial to improving the overall accommodating capacity of the material loading groove.

[0022] In one implementation, at least one partition is provided in the material loading tank, and the partition divides the material loading tank into at least two tank segments arranged in a direction around the connection through hole.

[0023] At this time, the partition divides the material loading tank into at least two tank segments arranged in a direction around the connection through hole, which is beneficial to independently place the required materials in each tank segment.

[0024] In one implementation, the metering system includes a weighing device for carrying a sample container; when projected in the direction of gravity, the first side wall of the weighing device has a first distance to the edge of the top connection frame, and the second side wall of the weighing device has a second distance to the edge of the top connection frame. The first side wall and the second side wall are oppositely arranged, and the first distance is less than the second distance; in the direction from the first side wall to the second side wall, the solid addition device and the liquid addition device are arranged.

[0025] At this time, the weighing device can conveniently weigh by carrying the sample container. In addition, the solid addition device and the liquid addition device are arranged in the direction from the first side wall to the second side wall, so that the liquid addition device can be arranged corresponding to the larger second distance, thereby providing a larger moving space for the liquid addition device.

[0027] At this time, the loading part of the weighing device is arranged inside the mounting cover, so that the mounting cover can provide protection for the sample container on the loading part, and the solid addition device and the liquid addition device can realize material injection through the material injection through hole. In addition, at least one door body is arranged on the same side as the first side wall, so that at least one door body can be arranged corresponding to the smaller first distance, thereby facilitating the operator to access and open the door body.

[0028] In one implementation, the sample preparation workstation further includes a memory and a driving circuit. The memory is used to store the pre-designed metering value; the metering system and the memory are respectively electrically connected to the driving circuit, and the driving circuit is electrically connected to the moving module; when the metering value of the metering system increases to be greater than or equal to the pre-designed metering value, the driving circuit is used to drive the moving module to move the solid addition device and / or the liquid addition device away from the sample container.

[0029] At this time, when the metering value of the metering system increases to be greater than or equal to the preset metering value, the sample preparation workstation can move the solid addition device and / or the liquid addition device away from the sample container, thereby completing a single sample preparation operation, thus improving the efficiency of the single sample preparation operation.

[0049] In laboratories in many fields such as scientific research, medical treatment, and chemical industry, sample preparation is usually required. For example, in the production of batteries such as lithium batteries and sodium batteries, laboratories sometimes need to prepare samples of electrolytes and passivators.

[0050] Traditional sample preparation mainly relies on manual operation, but the efficiency of manual operation is relatively low. In addition, in the case of preparing a large number of samples, the labor intensity of the operator is high and the overall preparation speed is slow. On the other hand, due to the differences in the operating habits and skill levels of different operators, and the possible interference of factors such as visual errors and hand tremors during the operation of the operator, it is easy to result in low accuracy of sample preparation, that is, it is difficult to ensure the accuracy of manual operation, which may affect the reliability and repeatability of experimental results.

[0051] To solve the problem of manual sample preparation, some sample preparation devices have emerged on the market. However, the sample preparation devices in the related technologies are usually large in volume and occupy a large amount of laboratory space.

[0052] Therefore, based on the above considerations, in order to reduce the occupied space, the present application proposes a sample preparation workstation. Among them, when the sample preparation workstation is in use, it can reduce the occupied space of the sample preparation workstation by installing a solid addition device and a liquid addition device.

[0053] Next, the structure of the sample preparation workstation proposed in the present application will be explained in detail with specific embodiments.

[0054] Refer to Figure 1 and Figure 2 , in an embodiment of the present application, the sample preparation workstation 100 includes a bracket 110, a moving module 120, a solid addition device 130, a liquid addition device 140, and a metering system 150. The moving module 120 is installed on the bracket 110; the solid addition device 130 is installed on the moving module 120, and the moving module 120 is used to move the solid addition device 130 towards the sample container 200; the solid addition device 130 has a solid output channel for delivering solid materials to the sample container 200; the liquid addition device 140 is installed on the moving module 120, and the moving module 120 is used to move the liquid addition device 140 towards the sample container 200; the liquid addition device 140 has a liquid output channel for delivering liquid materials to the sample container 200; the metering system 150 is connected to at least one of the sample container 200, the solid addition device 130, and the liquid addition device 140; the metering system 150 is used to correspondingly measure at least one of the total mass of the materials added to the sample container 200, the output amount of the solid materials output from the solid output channel, and the output amount of the liquid materials output from the liquid output channel.

[0055] Among them, the sample preparation workstation 100 can be understood as a workstation for sample preparation. For example, the sample preparation workstation 100 can be used to prepare samples of electrolytes and passivators. The bracket 110 can serve as the installation basis for the moving module 120, and the bracket 110 can be made of materials such as pipe fittings, plates, and profiles. The moving module 120 can be understood as a module that can move the components connected thereto. For example, it can move the solid addition device 130 and the liquid addition device 140. Among them, the moving module 120 can be set as a robotic arm, a guide rail and the corresponding slider, a lead screw and the corresponding nut, etc.

[0056] The solid addition device 130 can be understood as a device that can add solid materials to the sample container 200 through the above-mentioned solid output channel. The solid materials can be solid powders. At this time, the solid addition device 130 can be correspondingly set as a powder injector. Of course, the solid materials can also be solid particles, etc. In addition, the sample container 200 can be set as a sample bottle, a sample tray, etc. The liquid addition device 140 can be understood as a device that can add liquid materials to the sample container through the above-mentioned liquid output channel. For example, the liquid addition device 140 can include a peristaltic pump and the corresponding liquid injection tube. The peristaltic pump can output the liquid material in the liquid injection tube through the peristaltic action, so that the liquid material can be added to the above-mentioned sample container 200. Of course, the liquid addition device 140 can also be set as a liquid delivery pump. For example, the liquid addition device 140 can be set as a water pump, etc. This embodiment does not limit this.

[0057] The metering system 150 can be understood as a system that can measure the addition amount of materials. Among them, the metering system 150 can be connected to the sample container 200 to perform metering through the weight change of the sample container 200. For example, the metering system 150 can include a weighing device 151, and the weighing device 151 can be set as equipment such as an electronic balance. The weighing device 151 is used to carry the sample container 200, so that the weighing device 151 can conveniently perform weighing by carrying the sample container 200. Of course, the metering system 150 can also be connected to the solid addition device 130 to measure the output amount of the solid material through the weight reduction of the solid addition device 130. Or, the metering system 150 can measure the output amount of the solid material through the flow rate of the solid output channel of the solid addition device 130 and the corresponding output time. In addition, the metering system 150 can also be connected to the liquid addition device 140 to measure the output amount of the liquid material through the weight reduction of the liquid addition device 140. Or, the metering system 150 can measure the output amount of the liquid material through the flow rate of the liquid output channel of the liquid addition device 140 and the corresponding output time. This embodiment does not limit this.

[0058] According to the above analysis, when the sample preparation workstation 100 in this embodiment is in use, the solid addition device 130 and the liquid addition device 140 can be moved by the moving module 120 respectively, so that they can be quickly moved to the sample container 200 to add the required solid materials and liquid materials, and the metering of the feeding can be completed by the metering system 150, which is beneficial to reducing the transfer of the sample container 200 and the materials and reducing the overall operation time. In addition, the solid addition device 130 and the liquid addition device 140 are respectively installed on the moving module, which is beneficial to reducing the occupied space of the sample preparation workstation 100 compared with independently equipping the solid addition device 130 and the liquid addition device 140.

[0059] In some embodiments, referring to Figure 1 and Figure 2 , the bracket 110 includes a top connection frame 111 and at least three columns 112. The tops of the respective columns 112 are fixedly connected to the top connection frame 111 respectively, for example, by means of fasteners such as welding, screws or rivets for fixed connection. Among them, the column 112 can be set as a profile, for example, the column 112 can be set as an aluminum profile. In addition, the above-mentioned top connection frame 111 can also be formed by sequentially connecting profiles, for example, the profiles are sequentially connected to form a rectangular top connection frame 111. Among them, the respective columns 112 are arranged at intervals along the direction surrounding the top connection frame 111, and the top connection frame 111 and the respective columns 112 enclose an accommodation space 114; for example, Figure 1 , Figure 2 the bracket 110 in

[0060] Continue to refer to Figure 1 and Figure 2 , the above-mentioned moving module 120 is connected to the top connection frame 111, which can be understood as the moving module 120 is installed on the top connection frame 111. In addition, at least part of the moving module 120, at least part of the solid addition device 130, and at least part of the liquid addition device 140 are respectively arranged in the accommodation space 114. For example, a part of the lifting mechanism 123 of the moving module 120 is arranged in the accommodation space 114, and the solid addition device 130 and the liquid addition device 140 are respectively located in the accommodation space 114; on the other hand, referring to Figure 2 , the sample container 200 is used to be arranged in the accommodation space 114.

[0061] In this embodiment, the columns 112 are arranged at intervals along the direction surrounding the top connection frame 111, and the columns 112 are fixedly connected to the top connection frame 111, so as to improve the structural strength of the bracket 110 and suppress the shaking caused by the movement of the moving module 120. It can be understood that when the moving module 120 moves the solid addition device 130 and the liquid addition device 140, the overall sample preparation workstation 100 is relatively stable. In addition, at least part of the moving module 120, at least part of the solid addition device 130, and at least part of the liquid addition device 140 are respectively arranged in the accommodation space 114, and the sample container 200 is used to be arranged in the accommodation space 114, which is beneficial to further reduce the occupied space of the sample preparation workstation 100.

[0062] In some embodiments, with continued reference to Figure 1 and Figure 2 , the bracket 110 further includes a bottom connection frame 113, and the bottom parts of the columns 112 are respectively fixedly connected to the bottom connection frame 113, for example, by means of fasteners such as welding, screws or rivets for fixed connection. Among them, the bottom connection frame 113 can be formed by sequentially connecting profiles, for example, the profiles are sequentially connected to form a rectangular bottom connection frame 113.

[0063] In this embodiment, the bottom connection frame 113 can further improve the structural strength of the bracket 110, so as to further suppress the shaking caused by the movement of the moving module 120. In addition, the bottom connection frame 113 can increase the bottom support area of the bracket 110, thereby reducing the collision damage of the overall weight of the sample preparation workstation 100 to the test bench; it can be understood that for the test bench in contact with it, the bottom connection frame 113 can increase the contact area between the two, thereby reducing the local pressure and reducing the collision damage.

[0064] In some embodiments, with reference to Figure 1 and Figure 2 , the moving module 120 includes a first translation mechanism 121, a second translation mechanism 122 and a lifting mechanism 123. The first translation mechanism 121 is connected to the bracket 110, and it can be understood that the first translation mechanism 121 is installed on the bracket 110; the second translation mechanism 122 is connected to the first translation mechanism 121, and it can be understood that the second translation mechanism 122 is installed on the first translation mechanism 121. Among them, the first translation mechanism 121 and the second translation mechanism 122 can be understood as mechanisms capable of translating the components connected thereto; for example, the first translation mechanism 121 and the second translation mechanism 122 can translate the components connected thereto through screws and nuts, lead screws and nuts, and linear sliders.

[0065] In addition, the lifting mechanism 123 is connected to the second translation mechanism 122, which can be understood as the lifting mechanism 123 being installed on the second translation mechanism 122. Among them, the lifting mechanism 123 can be understood as a mechanism that can lift the components connected thereto; for example, the lifting mechanism 123 can lift the components connected thereto through screws and nuts, lead screws and nuts, and linear sliders.

[0066] Among them, the above-mentioned first translation mechanism 121 is used to move the second translation mechanism 122 in the first horizontal direction, for example, to move the second translation mechanism 122 in the Y-axis direction in the figure; the second translation mechanism 122 is used to move the lifting mechanism 123 in the second horizontal direction, for example, to move the lifting mechanism 123 in the X-axis direction in the figure; there is an angle between the second horizontal direction and the first horizontal direction. For example, the X-axis direction and the Y-axis direction in the figure are perpendicular to each other, and the first horizontal direction and the second horizontal direction are parallel to the Y-axis direction and the X-axis direction respectively. It can be understood that the angle between the above-mentioned first horizontal direction and the second horizontal direction can also be set to angles such as 30 degrees, 45 degrees, 60 degrees, 120 degrees, 150 degrees, etc., and this embodiment does not limit this.

[0067] In addition, the above-mentioned solid addition device 130 and liquid addition device 140 are respectively installed on the lifting mechanism 123, including being directly installed on the lifting mechanism 123 and being indirectly installed on the lifting mechanism 123 through other components; the lifting mechanism 123 is respectively used to lift the solid addition device 130 and the liquid addition device 140, for example, to move the solid addition device 130 and the liquid addition device 140 in the Z-axis direction in the figure.

[0068] In this embodiment, the first translation mechanism 121, the second translation mechanism 122, and the lifting mechanism 123 of the moving module 120 can quickly move the solid addition device 130 and the liquid addition device 140 to the corresponding sample container 200, for example, by moving along the X-axis, Y-axis, and Z-axis in the figure to reach the corresponding sample container 200, thereby reducing the overall operation time.

[0069] In some embodiments, referring to Figure 1 , the second translation mechanism 122 includes a lead screw 1221 and a guide rod 1222. The lead screw 1221 and the guide rod 1222 are respectively arranged to extend in the horizontal direction, and the extending direction of the lead screw 1221 is parallel to the extending direction of the guide rod 1222. For example Figure 1 the extending direction of the lead screw 1221 and the extending direction of the guide rod 1222 in Figure 3, the lifting mechanism 123 includes a threaded connection block 1231 and a guiding connection block 1232. The threaded connection block 1231 is fixedly connected to the guiding connection block 1232, for example, by integral molding, welding or other means. Among them, the threaded connection block 1231 is provided with a threaded through hole, and the threaded through hole is threadedly connected to the lead screw 1221, so as to achieve transmission through threaded connection. In addition, the guiding connection block 1232 is provided with a guiding through hole, and the guide rod 1222 is inserted into the guiding through hole, and the outer wall of the guide rod 1222 abuts against the hole wall of the guiding through hole, so that the guiding connection block 1232 can move along the extending direction of the guide rod 1222 to achieve guiding. On the other hand, the thickness direction of the threaded connection block 1231 and the thickness direction of the guiding connection block 1232 are respectively parallel to the extending direction of the guide rod 1222. For example, the thickness direction of the threaded connection block 1231 and the thickness direction of the guiding connection block 1232 are respectively parallel to the Figure 1 X-axis direction in, and the thickness of the threaded connection block 1231 is less than the thickness of the guiding connection block 1232. In some embodiments, referring to Figure 3 , the above-mentioned guiding connection blocks 1232 can be respectively provided on both sides of the threaded connection block 1231, so that the two relatively thick guiding connection blocks 1232 can enclose a concave cavity with the relatively thin threaded connection block 1231; correspondingly, the above-mentioned guide rods 1222 can be respectively provided on both sides of the lead screw 1221, and each guide rod 1222 is connected to the guiding through hole of the corresponding guiding connection block 1232, which is beneficial to further improve the guiding stability.

[0070] In this embodiment, the second translation mechanism 122 can achieve translation through the lead screw 1221, the guide rod 1222, the threaded connection block 1231 and the guiding connection block 1232; in addition, the thickness of the threaded connection block 1231 is less than the thickness of the guiding connection block 1232, so that the guiding stability can be improved through the guide rod 1222 and the relatively thick guiding connection block 1232, and the processing difficulty of the threaded through hole can be reduced through the relatively thin threaded connection block 1231; it can be understood that the axial length of the threaded through hole is relatively small, which is convenient for processing.

[0071] In some embodiments, referring to Figure 2 and Figure 3 , the sample preparation workstation 100 further includes a loading rack 160, and the loading rack 160 is at least used for carrying solid materials; of course, the loading rack 160 can also be used for carrying liquid materials. Among them, the solid materials can be directly placed on the loading rack 160, or the solid materials can be first placed in a solid container and then placed on the loading rack 160 through the solid container. Similarly, the liquid materials can be directly placed in the accommodating cavity of the loading rack 160; the liquid materials can also be first placed in a liquid container and then placed on the loading rack 160 through the liquid container.

[0072] In addition, the material carrier 160 is installed on the above-mentioned moving module 120, and the moving module 120 is used to move the material carrier 160 towards the sample container 200. On the other hand, the solid addition device 130 is relatively fixed to the material carrier 160; for example, the solid addition device 130 can be directly fixedly connected to the material carrier 160, or the solid addition device 130 can be indirectly connected to the material carrier 160 through other components. In addition, the solid output channel is used to convey solid materials from the material carrier 160 to the sample container 200, for example, the solid materials can be conveyed from the material carrier 160 to the sample container 200 through a powder injector.

[0073] In this embodiment, the material carrier 160 can at least carry a certain amount of solid materials, so as to continuously provide solid materials for different sample containers 200, which is conducive to realizing the continuous operation of multiple sample preparation operations. It can be understood that after the sample container 200 is loaded with a certain amount of materials, the sample container 200 can be removed by means of robotic arm clamping or manual removal.

[0074] In some embodiments, referring to Figure 2 and Figure 3 , the lifting mechanism 123 of the moving module 120 includes a lifting guide 1233 and a lifting connecting member. The lifting guide 1233 is arranged to extend along the direction of gravity, for example, the lifting guide 1233 is arranged to extend along the Z-axis direction in the figure. Among them, the lifting guide 1233 can be set as a lead screw or a linear guide rail, and the length direction of the lead screw and the length direction of the linear guide rail can be set to be along the direction of gravity. In addition, the lifting connecting member is connected to the lifting guide 1233, and the lifting connecting member is used to lift along the lifting guide 1233; for example, the lifting connecting member can be set as a nut connected to the lead screw, or the lifting connecting member is set as a slider connected to the linear guide rail, etc., so that the lifting connecting member can lift along the lifting guide 1233.

[0075] Correspondingly, continue to refer to Figure 2 and Figure 3 , the material carrier 160 is provided with a connecting through hole 161, and the lifting guide 1233 passes through the connecting through hole 161. It can be understood that the connecting through hole 161 also extends along the direction of gravity, so as to facilitate the lifting guide 1233 to pass through the connecting through hole 161. Among them, the lifting connecting member is arranged in the connecting through hole 161, and the lifting connecting member is connected to the hole wall of the connecting through hole 161, for example, fixed connection is carried out by means of fastener connection, welding, etc.

[0076] In this embodiment, the lifting guide member 1233 passes through the connection through-hole 161 of the loading rack 160. Thus, there is a mass distribution around the lifting guide member 1233 for the loading rack 160. It can be understood that a part of the loading rack 160 exists around the lifting guide member 1233, which is beneficial to reducing the deflection moment exerted by the loading rack 160 on the lifting guide member 1233. It can be understood that the forces around the lifting guide member 1233 are relatively uniform, which is beneficial to avoiding jamming and wear between the lifting connecting member and the lifting guide member 1233.

[0077] In some embodiments, referring to Figure 3 and Figure 4 , the loading rack 160 is provided with a loading groove 162. The loading groove 162 extends along a direction surrounding the connection through-hole 161. For example, in the figure, the loading groove 162 extends along a direction surrounding the Z-axis, so that the loading groove 162 is integrally annular. In some embodiments, at least one partition 163 may be provided in the loading groove 162. The partition 163 divides the loading groove 162 into at least two slot segments 164 arranged along a direction surrounding the connection through-hole 161. It can be understood that the respective slot segments 164 are arranged in a surrounding manner, which is beneficial to independently placing the required materials through the respective slot segments 164.

[0078] In this embodiment, the loading groove 162 of the loading rack 160 extends along a direction surrounding the connection through-hole 161, which is beneficial to improving the overall accommodation capacity of the loading groove 162. It can be understood that more materials can be accommodated.

[0079] In some embodiments, referring to Figure 1 , when projected along the direction of gravity, there is a first distance from the first side wall of the weighing device 151 to the edge of the top connection frame 111. For example, this first distance is located on the left side of the weighing device 151 in Figure 1 ; there is a second distance from the second side wall of the weighing device 151 to the edge of the top connection frame 111. For example, this second distance is located on the right side of the weighing device 151 in Figure 1 , that is, the first side wall and the second side wall are oppositely arranged. In addition, the first distance is less than the second distance. It can be understood that within the bracket 110, the space on one side (for example, the left side) of the weighing device 151 is smaller and the space on the other side (for example, the right side) is larger. Correspondingly, along the direction from the first side wall to the second side wall, for example, along the Figure 1 from left to right direction in

[0080] In this embodiment, the solid addition device 130 and the liquid addition device 140 are arranged along the direction from the first side wall to the second side wall. Thus, the liquid addition device 140 can be arranged corresponding to the larger second distance, for example Figure 1The liquid adding device 140 is arranged at the right position with a larger space in the figure, so as to provide a larger moving space for the liquid adding device 140. When the liquid adding device 140 includes a liquid connection pipeline, for example, when the liquid adding device 140 includes the above-mentioned liquid injection pipe, it is beneficial to avoid the liquid connection pipelines such as the liquid injection pipe being scratched and damaged.

[0081] In some embodiments, referring to Figure 1 and Figure 2 , the weighing device 151 includes a mounting cover 152, and the bearing part of the weighing device 151 is arranged inside the mounting cover 152; a feeding through hole 153 is provided at the top of the mounting cover 152, and the solid adding device 130 and the liquid adding device 140 are respectively used to move to be oppositely arranged with the feeding through hole 153, and the solid output channel and the liquid output channel are respectively used to convey solid materials and liquid materials to the sample container 200 through the feeding through hole 153. It can be understood that the solid adding device 130 and the liquid adding device 140 can output materials at the feeding through hole 153; of course, the solid adding device 130 and the liquid adding device 140 can also respectively include corresponding extension pipes, which are arranged to extend along the gravity direction and communicate with the corresponding solid output channel and liquid output channel, so that the extension pipes can pass through the feeding through hole 153 and extend into the mounting cover 152, so that the extension pipes can inject materials into the sample container 200.

[0082] In this embodiment, the bearing part of the weighing device 151 is arranged inside the mounting cover 152, so that the mounting cover 152 can provide protection for the sample container 200 on the bearing part, and the solid adding device 130 and the liquid adding device 140 can realize material injection through the feeding through hole 153.

[0083] In some embodiments, referring to Figure 1 , at least one side wall of the mounting cover 152 is provided with an openable door body 154, and at least one door body 154 and the first side wall are arranged on the same side, for example, at least one door body 154 is arranged on the Figure 1 left side in

[0084] In this embodiment, at least one door body 154 and the first side wall are arranged on the same side, so that at least one door body 154 can be arranged corresponding to the above-mentioned smaller first distance, so as to facilitate the operator to access and open the door body 154.

[0085] In some embodiments, the sample preparation workstation 100 further includes a memory and a driving circuit. The memory is used to store a pre-designed measurement value. The pre-designed measurement value may be the target value of the material in the sample container 200. The pre-designed measurement value may be pre-stored in the memory. It can be understood that the memory may be a high-speed random access memory (RAM) or a stable non-volatile memory (NVM), such as a disk memory.

[0086] In addition, the above-mentioned metering system 150 and the memory are respectively electrically connected to the driving circuit, and the driving circuit is electrically connected to the moving module 120. When the measurement value of the metering system 150 increases to be greater than or equal to the pre-designed measurement value, the driving circuit is used to drive the moving module 120 to move the solid addition device 130 and / or the liquid addition device 140 away from the sample container 200. The driving circuit may include a comparison circuit, a judgment circuit, etc., so as to facilitate signal output according to the measurement value of the metering system 150 and the pre-designed measurement value of the memory, and drive the above-mentioned driving circuit according to the output signal.

[0087] In some embodiments, when the measurement value of the metering system 150 increases to be greater than or equal to the pre-designed measurement value (such as the measurement value of solid materials), the driving circuit may be used to drive the moving module 120 to move the solid addition device 130 away from the sample container 200. In some embodiments, when the measurement value of the metering system 150 (such as the measurement value of liquid materials) increases to be greater than or equal to the pre-designed measurement value, the driving circuit may be used to drive the moving module 120 to move the liquid addition device 140 away from the sample container 200. This embodiment does not limit this.

[0088] In this embodiment, the sample preparation workstation 100 can move the solid addition device 130 and / or the liquid addition device 140 away from the sample container 200 when the measurement value of the metering system 150 increases to be greater than or equal to the pre-designed measurement value, thereby completing a single sample preparation operation and improving the efficiency of a single sample preparation operation.
