The experimental information at least includes material type, ratio, dosage, reaction temperature, stirring speed and intermediate reaction sampling interval.

[0050] The experimental information management module is used to receive the experimental information recommended by the database module and the evaluation module, and based on the time of receiving the experimental information, determines the latest experimental information as the target experimental information. The experimental information management module is used to collect the reaction spectra output by the intelligent experimental platform and the analysis and processing data of the spectra by the automatic spectrum analysis module.

[0053] The evaluation module is used to automatically evaluate and recommend the next batch of experimental information based on the target experimental information and the analysis and processing data of the automatic spectrum analysis module using a black box optimization algorithm.

[0054] Before the experiment begins, the task information of the experiment is first input through the instruction receiving module, for example, the maximum yield of a product under a certain reaction. After receiving the experimental task information, the instruction receiving module sends the experimental task information to the database module. The database module stores experimental history data, which includes data generated by literature, patents and platform experiments.

[0059] The experimental information management module is also used to receive the experimental information recommended by the evaluation module, and based on the time of receiving the experimental information, determine the latest experimental information as the above-mentioned target experimental information.

[0060] When the experiment information management module receives and determines the new target experiment information again, the above experiment is executed again.

[0061] After each experiment is executed, the experimental information management module records the analysis and processing data of the experiment and compares the analysis and processing data with the preset value. When the error between the target value in the analysis and processing data and the preset value is within an acceptable range, the experimental information management module terminates the cyclic experiment.

[0062] The organic chemistry intelligent experimental device provided by the present invention integrates the existing intelligent experimental platform with artificial intelligence technology, and can perform real-time prediction, planning, guidance, perception and optimization of the experimental situation.

[0063] In some embodiments, the intelligent experimental platform includes a sample table 100, a container temporary storage device 200, a second reaction container placement device 310, at least one stirring and heating device 400, a container transfer device, a liquid transfer device 500 and a reaction dynamic monitoring device.

[0065] Specifically, the container transfer device first transfers the reaction container on the sample stage 100 to the container temporary storage device 200, and the container transfer device and the container temporary storage device 200 cooperate to remove the cover of the reaction container, and then transfer the reaction container with the cover removed to the second reaction container placement device 310. Then, the container transfer device transfers the reagent container containing the required reagent on the sample stage 100 to the container temporary storage device 200, and removes the cover of the reagent container with the cooperation of the container transfer device and the container temporary storage device 200, and the liquid transfer device 500 transfers the reagent in the reagent container with the cover opened to the reaction container located on the second reaction container placement device 310. When all the required reagents are added to the reaction container, the container transfer device transfers the reaction container to the container temporary storage device 200, and screws back the cover of the reaction container with the cooperation of the container transfer device and the container temporary storage device 200. Then, the container transfer device transfers the reaction container to the stirring and heating device 400 for reaction.

[0066] The scheduling module adjusts the heating temperature of the stirring and heating device according to the corresponding reaction conditions in the target experiment information, or manually controls the heating temperature of the stirring and heating device.

[0067] During the reaction process, the container transfer device cooperates with the stirring and heating device to continuously open and close the reaction container cover. After the reaction container cover is opened, the reaction container monitoring device detects the substance in the reaction container and outputs a reaction spectrum.

The stirring and heating device 400 is provided with multiple, and each stirring and heating device 400 is provided with multiple third reaction vessel placement devices 410, so that multiple reaction vessels can be heated at the same time to improve work efficiency. Multiple stirring and heating devices 400 can regulate temperature respectively, and data when the same experiment reacts at different temperatures can be obtained, and multiple types of experiments with different heating temperatures can also be performed. Since it is necessary to continuously monitor the reaction process during the reaction, it is necessary to frequently perform the action of opening and closing the lid of the reaction vessel, therefore, a second clamping assembly is also provided on each third reaction vessel placement device 410, and when it is necessary to perform the action of opening or closing the lid, the second clamping assembly clamps the reaction vessel to prevent the reaction vessel from rotating, and when it is necessary to transfer the reaction vessel, the second clamping assembly releases the reaction vessel.

[0072] The container transfer device is used to transfer the reaction container and the reagent container, and to open and close the lids of the reaction container and the reagent container. The moving end of the container transfer device is used to move between the sample stage 100, the container temporary storage device 200, the second reaction container placement device 310 and the stirring and heating device 400 to complete the transfer of the reaction container or the reagent container.

[0073] The moving end of the container transfer device is provided with a rotating device 630 and a third clamping assembly 640, and the rotating device 630 is located between the moving end and the third clamping assembly 640. When the container transfer device transfers the container, the third clamping assembly 640 is used to grab the container. When the container is transferred to the right position, the third clamping assembly 640 releases the container and puts down the corresponding container. When the container transfer device performs the cover opening or closing action, the third clamping assembly 640 clamps the cover of the corresponding container, and at this time, the rotating device 630 drives the third clamping assembly 640 to rotate, thereby driving the cover to rotate to open or close.

[0074] The liquid transfer device 500 is mainly used to transfer the reagent in the reagent container on the container temporary storage device 200 to the reaction container on the second reaction container placement device 310. Therefore, the moving end of the liquid transfer device 500 is used to move between the container temporary storage device 200 and the second reaction container placement device 310. The liquid transfer device 500 can be a suction device that can suck the reagent in the reagent container and spray the reagent into the reaction container.

[0075] A gun tip storage device 130 is also provided on the sample table 100 , and a plurality of gun tip storage slots are provided in the gun tip storage device 130 . Before transferring the reagent, the moving end of the pipetting device 500 needs to move above the gun tip to be used and engage with the gun tip.

[0079] The first robot arm 610 can drive the rotating device 630 and the third clamping assembly 640 to transfer the reaction container from the sample stage 100 to the container temporary storage device 200. At this time, the rotating device 630, the third clamping assembly 640 and the container temporary storage device 200 cooperate to perform the action of opening the cover of the reaction container, and then the first robot arm 610 transfers the reaction container to the second reaction container placement device 310. After all the reagents are added to the reaction container, the reaction container is transferred back to the container temporary storage device 200, and the action of closing the cover of the reaction container is performed.

The second mechanical arm 620 drives the third clamping assembly 640 to drive the reaction container to move into the third reaction container placement device 410 of the stirring and heating device 400, and then the third clamping assembly 640 releases the reaction container.
