[0024] Combine the following Figure 1 , Figure 2 and Figure 3 The specific implementation of the intelligent filtrate injection device of the utility model is described.

[0025] The utility model provides an intelligent filtrate injection device, which realizes the grabbing of the syringe, the displacement of a fixed point, the installation of the filter at a fixed point, and the quantitative injection of the solution through a servo system. The intelligent filtrate injection device includes a workbench 12, a first fixed frame 1 and a second fixed frame 10, a translation servo slide 5, and an injection assembly. Among them, the workbench 12 is provided with a first fixed frame 1 and a second fixed frame 10, the first fixed frame 1 is provided with a positioning structure 13 for arranging a gas chromatography bottle, and the second fixed frame 10 is provided with a filter hole 7 for arranging a disposable filter. The translation servo slide 5 is arranged on the workbench 12. The injection assembly is arranged on the translation servo slide 5, so as to move laterally relative to the workbench 12 under the drive of the translation servo slide 5, and the injection assembly includes a vertical servo slide 2, an electric clamp 4 and a clamping servo push rod 6. The electric clamp 4 and the clamping servo push rod 6 are arranged on the vertical servo slide 2 to move vertically relative to the workbench 12 under the drive of the vertical servo slide 2. The electric clamp 4 is used to clamp the syringe, and the clamping servo push rod 6 is located above the electric clamp 4 and is used to press the piston rod of the syringe.

[0026] Specifically, as the basic platform of the entire device, a first fixing frame 1 and a second fixing frame 10 are set on the workbench 12. The first fixing frame 1 is used to fix the gas chromatography bottle, and a positioning structure 13 is provided on it to ensure the stability of the bottle during the injection process; the second fixing frame 10 is provided with a filter hole 7 for fixing the disposable filter to ensure that the position of the filter is accurate during use. The translation servo slide 5 is installed on the workbench 12, and can be driven by a servo motor to achieve precise movement in the horizontal direction, thereby driving the precise positioning of the injection assembly in the entire working area. The vertical servo slide 2 is installed on the translation servo slide 5, and can be driven by a servo motor to move up and down to adjust the position height of the syringe. The electric clamp 4 is installed on the vertical servo slide 2 to grab and fix the syringe to ensure the stability of the syringe during the injection process. The clamping servo push rod 6 is also installed on the vertical servo slide 2, located above the electric clamp 4, to simulate the manual pressing action, accurately control the movement of the syringe piston rod, and achieve accurate liquid delivery.

[0027] The intelligent filtrate injection device of the utility model is a device for intelligently installing filters and injecting liquid for laboratory syringes. As an important component of a fully intelligent laboratory, it replaces the pain points of fully manual and semi-automatic operations through fully automatic special machine sampling. The device realizes fully intelligent quantitative input of experimental solutions, ensures accurate installation of the filter and precise alignment of the injection point through servo positioning, greatly reduces the degree of manual participation, and thus significantly improves work efficiency and sampling accuracy. The utility model realizes automated filter installation and injection processes through mechanized injection components and precise servo control systems, significantly improving the safety, accuracy and efficiency of experimental operations.

[0028] According to the intelligent filtrate injection device provided by the utility model, a fixing sleeve 3 is provided on one side of the first fixing frame 1, and the fixing sleeve 3 has a bearing structure adapted to the syringe, and the electric clamp 4 of the injection assembly can clamp the syringe from the fixing sleeve 3. The function of the fixing sleeve 3 is to ensure that the syringe can be stably placed before being clamped by the electric clamp 4, and can be conveniently grasped by the electric clamp 4.

[0029] Specifically, during the preparation stage of the device, the syringe is placed in the fixed sleeve 3, and the design of the fixed sleeve 3 matches the syringes of different models to ensure that the syringe can be firmly placed in the fixed sleeve 3. When the device starts working, the translation servo slide 5 will move above the fixed sleeve 3 to ensure that the electric clamp 4 is in a concentric position with the fixed sleeve 3. At this time, the vertical servo slide 2 moves downward to bring the electric clamp 4 close to the syringe. The electric clamp 4 clamps the syringe while maintaining a reasonable upper and lower spacing. This reasonable spacing can be customized according to different syringe models to ensure that the syringe will neither get loose nor be subjected to unnecessary pressure during subsequent operations. Once the syringe is firmly clamped, the injection assembly (including the vertical servo slide 2 and the translation servo slide 5) will continue to perform the injection task according to the predetermined procedure, including moving to the second fixed frame 10 to install the filter screen, and accurately injecting the solution into the gas chromatography bottle.

[0030] According to an intelligent filtrate injection device provided by the utility model, a plurality of positioning structures 13 are arranged on the first fixed frame 1; and filter mesh holes 7 are arranged on the second fixed frame 10, the number of which is the same as that of the positioning structures 13 and the lateral positions of which are one-to-one corresponding. Specifically, when the intelligent filtrate injection device is working, the injection component will perform injection operations on the containers on each positioning structure 13 in turn. In this process, the injection component will first insert the syringe into the corresponding filter mesh hole 7 to ensure that the solution is filtered through the filter mesh before being injected into the container. In actual applications, gas chromatography bottles can be respectively arranged on the plurality of positioning structures 13 of the first fixed frame 1, and disposable filter meshes can be respectively preset in the plurality of filter mesh holes 7 of the second fixed frame 10. Then, the intelligent filtrate injection device is started, and the syringes are respectively operated in turn according to needs to perform quantitative injection.

[0031] According to the intelligent filtrate injection device provided by the utility model, a position sensor for detecting the lateral movement position of the injection component is arranged on the translation servo slide 5. The position sensor is mainly used to monitor the lateral movement position of the injection component on the translation servo slide 5, to ensure that the injection component can be accurately moved to the position of each gas chromatography bottle, and to accurately align each filter mesh hole 7 during the injection process. The position sensor can feed back the current position information of the injection component to the control system in real time, to ensure that the injection component can stop at the correct lateral position, thereby ensuring that the syringe can be accurately aligned with the gas chromatography bottle, and to ensure that the position of the syringe when passing through the filter mesh hole 7 is accurate.

[0032] According to an intelligent filtrate injection device provided by the utility model, the second fixed frame 10 includes a top plate provided with a plurality of filter mesh holes 7, and two side plates located at both ends of the length direction of the top plate and supported between the top plate and the workbench 12; the top plate and the two side plates and the workbench 12 enclose a lower space for accommodating the first fixed frame 1. By placing the first fixed frame 1 in the space below the second fixed frame 10, the space of the workbench 12 is saved, making the entire device more compact and facilitating efficient experimental operations in a limited space. After installing the disposable filter, the syringe can be directly aimed downward at the gas chromatography bottle below for injection without the need for additional moving steps, which simplifies the entire injection process and improves work efficiency.

[0033] According to an intelligent filtrate injection device provided by the utility model, a linear slide 9 is arranged between the first fixed frame 1 and the workbench 12; the first fixed frame 1 can move along the linear slide 9 to move between the injection position and the material taking position; in the injection position, the first fixed frame 1 is located in the lower space, and the positioning structure 13 is aligned with the filter mesh hole 7; in the material taking position, the first fixed frame 1 is located outside the lower space, so as to load and unload the gas chromatography bottle on the positioning structure 13. Specifically, when in the injection position, the first fixed frame 1 is located in the lower space, and the positioning structure 13 is aligned with the filter mesh hole 7 on the top plate of the second fixed frame 10, so that each gas chromatography bottle has a corresponding filter mesh hole 7 above, ensuring that the solution can be accurately injected into the gas chromatography bottle after being filtered by the filter mesh. In the material taking position, the first fixed frame 1 is located outside the lower space, that is, it leaves the area below the top plate, so that the operator can easily load and unload the gas chromatography bottle on the positioning structure 13, which is convenient for replacing or replenishing the container to be injected. Before starting the injection, the first fixed frame 1 moves to the material taking position, and the operator can place or replace the gas chromatography bottle on the positioning structure 13. After completion, the first fixed frame 1 will move back to the injection position along the linear slide rail 9, and the gas chromatography bottle is just below the corresponding filter hole 7, ready for the injection operation.

[0034] In some application scenarios, the first fixed frame 1 can be moved manually along the linear slide rail 9. In order to improve the operating efficiency and accuracy, the preferred method is to use a translation servo push rod 11 to drive the movement of the first fixed frame 1. Preferably, according to an intelligent filtrate injection device provided by the utility model, a translation servo push rod 11 is arranged between the first fixed frame 1 and the workbench 12, and the translation servo push rod 11 can drive the first fixed frame 1 to move along the linear slide rail 9. Before starting the injection, the translation servo push rod 11 drives the first fixed frame 1 to move to the material taking position, and the operator can place or replace the gas chromatography bottle on the positioning structure 13. After completion, the translation servo push rod 11 drives the first fixed frame 1 back to the injection position, at which time the gas chromatography bottle is just below the corresponding filter mesh hole 7, ready for the injection operation.

[0035] According to an intelligent filtrate injection device provided by the utility model, a push plate 14 parallel to the horizontal plane is provided at the driving end of the clamping servo push rod 6. The function of the push plate 14 is to contact the piston rod of the syringe and apply a stable force during the injection process to control the movement of the piston rod. In order to further improve the contact stability and anti-skid performance between the push plate 14 and the syringe piston rod, an anti-skid layer can be provided on the lower surface of the push plate 14 to increase the friction between the push plate 14 and the syringe piston rod, thereby ensuring that the push plate 14 can stably push the piston rod during the injection process to avoid inaccurate liquid volume caused by sliding. The anti-skid layer can be made of a material with a high friction coefficient, such as rubber or Teflon.

[0036] According to an intelligent filtrate injection device provided by the utility model, a waste bucket is provided on one side of the workbench 12; the lateral movement path of the injection assembly includes an initial position, and in the initial position, the electric clamp 4 is located directly above the waste bucket. After completing the injection operation, the injection assembly will return to the initial position with the discarded syringe. Once the initial position is reached, the electric clamp 4 will be released, and the syringe with the filter will be directly discarded into the waste bucket, which can effectively manage waste and reduce the risk of pollution. In this way, the processing process of discarded syringes is fully automated, which not only improves the safety of laboratory operations, but also reduces the workload of operators and improves overall efficiency.

[0037] According to an intelligent filtrate injection device provided by the utility model, a drag chain 8 is arranged on the workbench 12; the fixed end of the drag chain 8 is installed on one side of the workbench 12, and the movable end of the drag chain 8 is installed on the translation servo slide 5, and is relatively fixed with the lateral position of the injection component; the power supply cable and the communication cable connected to the injection component are stored in the drag chain 8. The drag chain 8 is a device for protecting cables and pipelines, which is composed of a series of connected segments and can be stretched or folded as the injection component moves. The power supply cable and the communication cable are stored by the drag chain 8 to ensure that when the injection component moves laterally, the cables can smoothly follow the movement without twisting or pulling, thereby avoiding damage to the cables or safety hazards.

[0038] According to the intelligent filtrate injection device of the preferred embodiment of the utility model, in the initial state, the horizontal servo slide retreats to the rearmost position to facilitate the placement of the front-end syringe; the vertical servo slide 2 rises to the uppermost part, and the clamping servo push rod 6 also rises to the uppermost part. The specific working process is as follows: in the initial state, the horizontal servo slide retreats to the rearmost position to facilitate the placement of the front-end syringe; the vertical servo slide 2 rises to the uppermost part, and the clamping servo push rod 6 also rises to the uppermost part. After placing the syringe into the fixed sleeve 3, the translation servo slide 5 moves forward to the top of the fixed sleeve 3 to ensure that the electric clamp 4 is in a concentric position with the fixed sleeve 3. The vertical servo slide 2 moves downward to ensure that the electric clamp 4 clamps the syringe and maintains a reasonable upper and lower spacing. The vertical servo slide 2 rises to a specified distance, the translation servo slide 5 moves to the left to a position concentric with the filter screen hole 7, and the vertical servo slide 2 descends a specified distance to perform the step of installing the disposable filter screen. The compression servo push rod 6 moves, and the push plate 14 presses down the syringe piston, so that the liquid inside the syringe is quantitatively injected into the gas chromatography bottle through the disposable filter. The advancement distance can be adjusted in real time as needed. After the injection is completed, the translation servo slide 5 drives the first fixed frame 1 to move along the linear slide rail 9 to the material collection position, waiting to be taken away. The device drives the discarded syringe back to the initial position. After reaching the initial position, release the electric clamp 4 and throw the syringe with the disposable filter into the discarded bucket. After completing the above steps, the above operations are automatically repeated, and the cycle is repeated.

[0039] Through the above process, the intelligent filtrate injection device provided by the utility model realizes an automated, precise and efficient injection process, which significantly improves the efficiency and accuracy of experimental operations.
