[0025] The following example illustrates the operation process of the automated electrochemical experimental platform 1 according to an embodiment of the present invention.

[0026] The "Set Sequence" operation allows you to set the operating sequence for the automated electrochemical experimental platform 1 according to the required electrochemical experiments. Operators can set the operating sequence themselves, or different operating sequences can be preset for different electrochemical experiments.

[0027] "Solid sample addition" operation: The robotic arm 100 grabs the sample bottle 31 and places it in the designated position in the solid sample addition device 40. The robotic arm 100 grabs the powder cylinder 21 and places it in the designated position in the solid sample addition device 40. The solid sample addition device 40 adds solid sample. After the weight reaches the set standard, the addition stops. The robotic arm 100 grabs the powder cylinder 21 in the solid sample addition device 40 and puts it back in the designated position in the powder cylinder holder 20. The robotic arm 100 grabs the sample bottle 31 in the solid sample addition device 40 and places it in the designated position for the subsequent process.

[0028] "Liquid Sampling" Operation: The robotic arm 100 grasps the sample bottle 31, places the sample bottle 31 in the designated position of the liquid sampling device 50, injects a predetermined volume of liquid reagent from the liquid reagent bottle into the sample bottle 31, and the robotic arm 100 grasps the sample bottle 31 located in the liquid sampling device 50 and places the sample bottle 31 in the designated position of the subsequent process.

After the solubilization is completed, the robotic arm 100 picks up the sample bottle 31 in the solubilization device 60 and places it in the designated position for the subsequent process.

[0030] Electrochemical testing operation: The robotic arm 100 grasps the sample vial 31, places it in the sampling device 70, draws a specified volume of liquid from the sample vial 31, and injects it into the microchannel flow electrolytic cell 80; the electrochemical measuring device 90 performs electrochemical experiments on the liquid in the microchannel flow electrolytic cell 80.

[0033] The automated electrochemical experimental platform 1 according to an embodiment of the present invention, by setting up liquid reagent bottles, powder cylinder racks 20, sample bottle boxes 30, solid sample dispensing devices 40, liquid sample dispensing devices 50, solubilizing devices 60, sampling devices 70, microchannel flow electrolytic cells 80, electrochemical measuring devices 90, and robotic arms 100, can move sample bottles 31 between different devices using the robotic arm 100 to realize operations such as solid sample dispensing, liquid sample dispensing, solubilizing, and electrochemical testing. Compared with electrochemical experimental platforms in related technologies, it can improve the overall automation level of experimental operations, realize the fully automated operation from sample dispensing to sampling to experiment, avoid problems such as large workload of manual operation and human factors affecting experimental results, improve experimental efficiency, and facilitate the realization of high-throughput and standardized experimental requirements.

[0034] Therefore, the automated electrochemical experimental platform 1 according to the embodiments of the present invention has advantages such as high degree of automation, high experimental efficiency, and ease of achieving high-throughput and standardized experimental requirements.

[0035] The automated electrochemical experimental platform 1 according to a specific embodiment of the present invention is described below with reference to the accompanying drawings.

[0036] In some specific embodiments of the present invention, such as Figure 1As shown, the automated electrochemical experimental platform 1 according to an embodiment of the present invention includes a liquid reagent bottle, a powder cylinder rack 20, a sample bottle box 30, a solid sample dispensing device 40, a liquid sample dispensing device 50, a solubilizing device 60, a sampling device 70, a microchannel flow electrolytic cell 80, an electrochemical measuring device 90, and a robotic arm 100.

[0037] Specifically, such as Figure 1 As shown, the automated electrochemical experimental platform 1 also includes a substrate 110, liquid reagent bottles 10, powder cartridge holders 20, sample bottle boxes 30, solid sample dispensing devices 40, liquid sample dispensing devices 50, solubilizing devices 60, sampling devices 70, microchannel flow electrolytic cells 80, electrochemical measuring devices 90, and a robotic arm 100, all mounted on the substrate 110. This facilitates the positioning of the liquid reagent bottles, powder cartridge holders 20, sample bottle boxes 30, solid sample dispensing devices 40, liquid sample dispensing devices 50, solubilizing devices 60, sampling devices 70, microchannel flow electrolytic cells 80, and electrochemical measuring devices 90, facilitates the accurate grasping of sample bottles 31 by the robotic arm 100, and facilitates the setting of the robotic arm 100's movement program.

[0038] More specifically, such as Figure 1 As shown, the automated electrochemical experimental platform 1 also includes a guide rail 120, which is disposed on the substrate 110, and a robotic arm 100 is movably disposed on the guide rail 120. Specifically, it also includes a drive device, which is connected to the robotic arm 100 to drive the robotic arm 100 to move on the guide rail 120. This facilitates the overall movement of the robotic arm 100, allows for a larger range of motion of the robotic arm 100, and facilitates the arrangement of the various devices of the automated electrochemical experimental platform 1.

[0039] Furthermore, such as Figure 1 As shown, the powder cylinder holder 20, solid sample dispensing device 40, liquid sample dispensing device 50, solvent aid device 60, and sampling device 70 are arranged sequentially along the length of the substrate 110, and the guide rail 120 is oriented along the length of the substrate 110. This facilitates the movement of the robotic arm 100 between adjacent process devices, shortens the movement time of the robotic arm 100, and improves the overall efficiency of the experiment.

[0040] Advantageously, the liquid reagent bottle is connected to the liquid dispensing device 50 via a liquid delivery tube, and the sampling device 70 is connected to the electrochemical measuring device 90 via a liquid delivery tube. This facilitates the flow of liquid reagents between different devices.

[0041] More advantageously, the automated electrochemical experimental platform 1 also includes a waste liquid bottle, with the liquid loading device 50, microchannel flow electrolytic cell 80, and sampling device 70 all connected to the waste liquid bottle. Specifically, before the liquid reagent bottle delivers the liquid reagent to the target device through the liquid delivery tube, the liquid reagent is first delivered to the waste liquid bottle through the liquid delivery tube to rinse the liquid delivery tube. This allows the liquid delivery tube to be cleaned with the liquid reagent in the liquid reagent bottle before the liquid reagent is delivered to the target device, and the cleaned liquid reagent is then delivered to the waste liquid bottle, avoiding interference between different liquid reagents that could affect the experimental results.

[0042] Both the liquid reagent bottle and the storage bottle can be the same type of storage bottle 10. In other words, the automated electrochemical experimental platform 1 can include multiple storage bottles 10, some of which are used to store liquid reagents, and others are used to store waste liquid after cleaning the tubing. Some of the multiple storage bottles 10 can also store cleaning solution, reference solution, blank solution, and other liquids that may be used or generated in the electrochemical experiment. The liquids in the multiple storage bottles 10 can be replaced according to the needs of different electrochemical experiments.

[0043] Furthermore, the automated electrochemical experimental platform 1 also includes a pumping device 130 connected to the liquid delivery tube. Specifically, there can be multiple pumping devices 130. This facilitates the provision of driving force for the delivery of liquid reagents.

[0044] Furthermore, the pumping device 130 is connected to the waste liquid bottle via a waste liquid pipe, and the pumping device 130 can switch between a liquid guiding state connected to the liquid guiding pipe and a waste liquid state connected to the waste liquid pipe. Specifically, the pumping device 130 can switch to the liquid guiding state when it is necessary to clean the liquid guiding pipe or to deliver the liquid reagent to the target device, thus guiding the liquid reagent in the liquid reagent bottle through the liquid guiding pipe. When it is not necessary to clean the liquid guiding pipe, but it is necessary to drain the liquid reagent remaining in the pipeline and the pumping device 130, the pumping device 130 can switch to the waste liquid state, directly discharging the liquid into the waste liquid bottle. This facilitates the drainage of the liquid reagent remaining in the pipeline and the pumping device 130.

[0045] Optionally, the solubilizing device 60 is adapted to hold multiple sample vials 31, and the sampling device 70 is adapted to hold multiple sample vials 31. This facilitates the solubilizing device 60 to simultaneously perform solubilizing operations on multiple sample vials 31, and facilitates the sampling device 70 to simultaneously perform sampling operations on multiple sample vials 31, further improving the overall experimental efficiency of the automated electrochemical experimental platform 1.

[0046] Optionally, the powder container rack 20 is suitable for holding multiple powder containers 21, and the sample bottle box 30 is suitable for holding multiple sample bottles 31. This facilitates the storage of various powdered reagents and allows for simultaneous operation on multiple sample bottles 31. For example, the robotic arm 100 can first grasp one sample bottle 31 for sample addition and dissolution, and then, while waiting for dissolution, grasp another sample bottle 31 for sample addition, thereby further improving the overall experimental efficiency of the automated electrochemical experimental platform 1.

[0047] Specifically, the sample bottle 31, powder cylinder 21, pumping device 130, microchannel flow electrolysis cell 80, liquid guide tube, and storage bottle 10 are made of materials that are resistant to acid, alkali, oxidation, corrosion, and organic solvents.

[0048] The solubilizing device 60 can be one or more of the following: shaking, heating, stirring, water bath, oil bath, sand bath, and metal bath. A metal bath solubilizing device is preferred.

[0049] The microchannel flow electrolyzer 80 may be equipped with multiple interfaces, which are detachably connected to an inlet pipe, an outlet pipe, a working electrode, a counter electrode, and a reference electrode. The working electrode, counter electrode, and reference electrode may be metal wires or graphite rods, and a catalyst layer may be disposed on the working electrode, counter electrode, and reference electrode. The reference electrode may include a glass tube and a metal wire, with the metal wire sleeved on the outside of the glass tube.

[0050] The liquid storage bottle 10, powder cylinder rack 20, sample bottle box 30, solid sample dispensing device 40, liquid sample dispensing device 50, solubilizing device 60, sampling device 70, microchannel flow electrolytic cell 80, electrochemical measuring device 90 and robotic arm 100 are detachably mounted on the substrate 110.
