Description

Technical Field

[0001] This application relates to the field of materials preparation technology, and in particular to a flash Joule heating device and control method, electronic equipment and storage medium. Background Technology

[0002] Flash Joule heating (FJH) is an emerging advanced materials preparation technology that uses millisecond-level high-current pulses to rapidly heat conductive precursors to temperatures above 3000K, enabling the rapid, energy-efficient, and solvent-free synthesis of high-performance materials such as graphene, silicon carbide, and nanocomposite materials. Due to its high efficiency and environmental friendliness, this technology holds great promise for applications in new energy, electronic devices, and other fields.

[0003] In related technologies, flash Joule heating equipment is mostly a single-station manual or semi-automatic system. When preparing the target material, the operator needs to first load the precursor powder into the reaction vessel, manually place the vessel between two electrodes, and then manually trigger a high-voltage pulse power supply for heating. After heating, the operator removes the product from the reaction vessel and cleans it. Although some studies have attempted to introduce robotic arms or conveyor belts to improve automation, these solutions typically only automate a single step and cannot achieve closed-loop control of the entire process from filling, detection, alignment to heating.

[0026] Please refer to Figure 1This application provides a flash Joule heating device 10 for heating a reaction vessel to heat the reactants in the reaction vessel to form a target product. The flash Joule heating device 10 includes a first stage assembly 101, with the reaction vessel disposed within the plane of the first stage assembly 101. The first stage assembly 101 is used to load reactants into the reaction vessel and measure the first resistivity of the reactants in the reaction vessel.

[0027] The flash Joule heating device 10 includes a second stage assembly 102. A reaction vessel containing reactants can be positioned within the plane of the second stage assembly 102, which is used to heat the reaction vessel.

[0028] The flash Joule heating device 10 includes a positioning assembly 103. The positioning assembly 103 is used to determine a first actual position of the reaction vessel within the plane of the first stage assembly 101.

[0029] The flash Joule heating device 10 includes a transfer assembly 104. The transfer assembly 104 is used to transfer the reaction vessel from a first actual position to a target position pre-configured within the plane of the second stage assembly 102.

[0030] The flash Joule heating device 10 includes a controller 105. The controller 105 is communicatively connected to the first worktable assembly 101, the second worktable assembly 102, the positioning assembly 103, and the transfer assembly 104.

[0031] The first workbench assembly 101 and the second workbench assembly 102 each have a working plane, which can be set on the same horizontal plane to reduce the transfer difficulty of the transfer assembly 104 and improve the transfer efficiency. The first workbench assembly 101 has a storage chamber for temporarily storing reactants. The storage chamber has an inlet and an outlet. The inlet can be set above the storage chamber, and the outlet is set below the storage chamber. A mounting platform is set on the working plane of the first workbench assembly 101 for setting the reaction vessel. When the reaction vessel is set on the mounting platform, the reactants stored in the storage chamber can flow directly into the reaction vessel through the outlet. The transfer assembly 104 can be a high-precision robotic arm. The transfer assembly 104 can be set between the first workbench assembly 101 and the second workbench assembly 102 to facilitate the transfer of the reaction vessel between the two working planes. The positioning assembly 103 is set outside the first workbench assembly 101 and the second workbench assembly 102 to obtain a complete view of the working planes of the first workbench assembly 101 and the second workbench assembly 102.

[0032] Thus, the flash Joule heating device 10 provided in this application embodiment, by integrating a first workbench assembly 101, a second workbench assembly 102, a positioning assembly 103, a transfer assembly 104, and a controller 105, achieves fully automated operation of the entire process, including reactant loading, resistivity measurement, reaction vessel positioning, automatic transfer, and real-time temperature monitoring during heating. This reduces manual intervention and improves experimental efficiency and data accuracy. Specifically, the positioning assembly 103 can determine the first actual position of the reaction vessel within the plane of the first workbench 1011, while the transfer assembly 104 can stably transfer the reaction vessel to the target position on the second workbench 1021. The design of the two workbench planes being on the same horizontal plane reduces transfer complexity and positioning errors. Furthermore, the integrated structure of the storage chamber and the placement stage in the first workbench assembly 101 allows reactants to be directly loaded into the reaction vessel, simplifying the operation steps and reducing the influence of human factors. The controller 105's coordinated control of each component ensures the repeatability and safety of the heating process, thereby achieving the goal of improving the automation level, ease of operation, and reliability of experimental results in the flash Joule heating process.

[0033] In some embodiments, the first workbench assembly 101 includes a first workbench 1011 and a filling mechanism 1012. The filling mechanism 1012 is disposed above the first workbench 1011 and is used to store reactants and fill the reactants into the reaction vessel.

[0034] The filling mechanism 1012 may include a storage chamber and a discharge port. The storage chamber has a feed port on the side opposite to the first workbench 1011 to facilitate the replenishment of reactants into the storage chamber by the operator. The discharge port is located on the side of the storage chamber close to the first workbench 1011, and the reactants in the storage chamber can flow out of the storage chamber through the discharge port and be received by the reaction vessel below.

[0035] The first workbench assembly 101 includes a compaction mechanism 1013. The compaction mechanism 1013 is disposed on the first workbench 1011 and below the filling mechanism 1012. The compaction mechanism 1013 is communicatively connected to the controller 105 and is used to drive the reaction vessel to vibrate, thereby compacting the reactants filled into the reaction vessel. The operator can configure the discharge rate of each filling into the reaction vessel in the controller 105. When the discharge rate is reached, the controller 105 automatically closes the discharge port.

[0036] Specifically, the compaction mechanism 1013 can be located below the mounting platform. The compaction mechanism 1013 may include a vibrating element, the power component may be a motor, and the vibrating element may be a frequency-modulated vibrator. After the filling mechanism 1012 completes the filling, the controller 105 can control the vibrating element to start vibrating according to the pre-configured vibration frequency and amplitude to make the reactants in the reaction vessel more compact.

[0037] The first workbench assembly 101 includes a resistivity detection mechanism 1014. The resistivity detection mechanism 1014 is disposed on the first workbench 1011 and is communicatively connected to the controller 105. The resistivity detection mechanism 1014 is used to detect the resistivity of the compacted reactants in the reaction vessel.

[0038] The resistivity detection mechanism 1014 includes four probes and a probe holder. The four probes can be arranged in a straight line with the same spacing. When measuring the first resistivity, the four probes are first inserted into the reactant, and then a constant current is passed through the two probes at both ends and the potential difference between the two probes in the middle is measured to determine the first resistivity of the reactant.

[0039] The above embodiments integrate a filling mechanism 1012, a compaction mechanism 1013, and a resistivity detection mechanism 1014 in the first workbench assembly 101, and control the relevant mechanisms through a controller 105. This improves the automation, consistency, and measurement accuracy of the flash Joule heating device 10 during the reactant loading stage, reduces human error, and ensures the uniformity and repeatability of the subsequent heating process.

[0040] In some embodiments, the second workbench assembly 102 includes a second workbench 1021. The second workbench 1021 is disposed on one side of the first workbench 1011.

[0041] The second workbench assembly 102 includes a power supply 1022. The power supply 1022 is located on the second workbench 1021 and is communicatively connected to the controller 105.

[0042] The second worktable assembly 102 includes at least one pair of heating electrodes electrically connected to a power supply 1022. The heating electrodes are used to hold the reaction vessel and are capable of heating the reaction vessel when energized.

[0043] Specifically, the second workbench 1021 and the first workbench 1011 are arranged on the same horizontal plane. A power supply 1022 is installed on the second workbench 1021. Exemplarily, this power supply 1022 can be a high-voltage pulse power supply 1022, capable of outputting a peak current of not less than 10kA and an output pulse width range of 0.1~100ms. At least one pair of heating electrodes is arranged above the second workbench 1021. These heating electrodes can be graphite electrodes, tungsten electrodes, or molybdenum electrodes, etc. The heating electrodes are electrically connected to the power supply 1022. When the heating electrodes clamp the reaction vessel, the power supply 1022 can supply high-voltage pulses to the heating electrodes to heat the reaction vessel.

[0044] The second workbench assembly 102 may further include a temperature measuring mechanism 1023. The temperature measuring mechanism 1023 is disposed on the second workbench 1021 and communicatively connected to the controller 105. The temperature measuring mechanism 1023 is used to acquire real-time temperature data of the reactants during the heating process. The temperature measuring mechanism 1023 includes a thermometer and a thermocouple. The thermometer can be an infrared thermometer, and the thermocouple can be a type K thermocouple. The real-time temperature data acquisition frequency is set to be no less than 1 kHz to monitor the temperature of the reactants in the reaction vessel in real time during the heating process.

[0045] In the above embodiments, by incorporating a power supply 1022, heating electrodes, and a temperature measuring mechanism 1023 into the second workbench assembly 102, the flash Joule heating device 10 is provided with efficient, controllable, and precise heating capabilities. Placing the first workbench 1011 and the second workbench 1021 on the same horizontal plane facilitates the smooth transfer of the reaction vessel by the transfer assembly 104, reducing operational complexity. The high-voltage pulse power supply 1022, in conjunction with the high-temperature resistant heating electrodes, enables rapid, high-power Joule heating of the reaction vessel, meeting the requirements of the flash high-temperature synthesis process. Furthermore, the temperature measuring mechanism 1023 acquires real-time temperature data of the reactants, ensuring accurate capture of transient temperature changes during heating. The controller 105 enables communication and linkage between the components, allowing heating parameters to be dynamically adjusted based on the resistivity measured by the first workbench 1011. This ensures precise control and safety of the thermal reaction process while maintaining heating efficiency, and achieves experimental repeatability and product quality consistency.

[0046] In some embodiments, the positioning component 103 includes an image acquisition element. The image acquisition element is disposed on the first worktable 1011 and communicatively connected to the controller 105. The image acquisition element is used to acquire a position image of the reaction vessel within the plane of the first worktable 1011.

[0047] The positioning assembly 103 includes a laser positioning element. The laser positioning element is disposed on the first worktable 1011 and is communicatively connected to the controller 105. The laser positioning element is used to emit a laser beam toward the plane of the first worktable 1011 to determine the first actual position of the reaction vessel.

[0048] The image acquisition element can be a CCD camera, and the laser positioning element can be a laser positioner. The image acquisition element and the laser positioning element can be arranged vertically or side-by-side on the same horizontal plane. For example, the image acquisition element and the laser positioning element can be positioned at the first corner of the first worktable 1011. When the image acquisition element is positioned at the first corner, it can acquire a relatively clear image reflecting the position of the reaction container on the first worktable 1011. When the laser positioning element is positioned at this corner, the ranging beam emitted by the laser positioning element can directly target the reaction container, meaning there are no other obstacles between the reaction container and the laser positioning element. The image acquisition element can acquire an image of the position of the reaction container on the first worktable 1011 and send it to the controller 105. The controller 105 can determine the direction of the reaction container relative to the positioning component 103 based on this image, and then control the laser emitting part of the laser positioning element to face the reaction container and emit a laser. A coordinate system is pre-set in the controller 105, which can reflect the positions of components such as the reaction container, the first worktable 1011, and the second worktable 1021 in coordinate form. The controller 105 can determine the coordinates of the reaction vessel in a predetermined coordinate system based on the relevant data fed back by the image acquisition element and the laser emission element, thus realizing the determination of the first actual position of the reaction vessel.

[0049] In the above embodiment, an image acquisition element acquires an image of the reaction container's position within the plane of the first worktable 1011. Based on this image, the controller 105 determines the container's approximate orientation and then drives a laser positioning element to emit a laser beam towards the target. This acquires the reaction container's coordinates in a preset coordinate system, thereby determining the first actual position of the reaction container on the first worktable 1011. The combination of the image acquisition element and the laser positioning element effectively overcomes the limitations of a single sensor in terms of field of view or accuracy. This not only improves the accuracy of the determined reaction container's position but also provides precise pose data for the automatic grasping and transfer of the transfer assembly 104, thereby reducing alignment errors and improving the transfer efficiency of the reaction container from the first worktable 1011 to the second worktable 1021.

[0050] In some embodiments, the positioning assembly 103 further includes a positioning calibration element. The positioning calibration element is disposed on the second stage 1021 and communicatively connected to the controller 105, and the positioning calibration element is capable of acquiring a second actual position of the reaction vessel on the second stage 1021.

[0051] Specifically, the positioning calibration element can be set at the second corner of the second worktable 1021, and the positioning calibration element can be an inductive position calibrator. When the positioning calibration element is set at the second corner, it can obtain the second actual position of the reaction vessel on the second worktable 1021 and send the second actual position to the controller 105. The controller 105 controls the transfer assembly 104 to fine-tune the position of the reaction vessel on the second worktable 1021 based on the deviation between the second actual position and the target position pre-configured in the controller 105, so that the reaction vessel can be set at the target position.

[0052] The above embodiment achieves accurate detection and closed-loop position correction of the second actual position of the reaction vessel by adding a positioning and calibration element on the second worktable 1021. This improves the alignment accuracy and operational reliability of the flash Joule heating device 10 before heating and effectively avoids problems such as uneven heating, arcing, or even equipment damage caused by electrode clamping misalignment or poor contact. This ensures stable electrical contact between the heating electrode and the reaction vessel and improves the safety of the process of preparing the target material.

[0053] Based on the above, this application also provides a control method for a flash Joule heating device. This control method is applied to the flash Joule heating device provided in the above embodiments. Specifically, this control method can be applied to the controller of the flash Joule heating device. Figure 2 As shown, the control method of the flash Joule heating device can be implemented through steps 201 to 204: Step 201: The controller acquires and determines the heating parameters based on the first resistivity, and configures the heating parameters into the second workbench assembly.

[0054] Specifically, when the preparation of the target product begins, the operator first places the reaction vessel in a fixed position within the first stage assembly. When the reaction vessel is in this fixed position, the reactants in the storage chamber flow into the reaction vessel through the outlet. The first stage assembly then measures the resistivity of the reactants in the reaction vessel using a four-probe method and sends the measurement to the controller. Based on the first resistivity of the reactants in the reaction vessel, the controller determines the heating parameters for preparing the target material under the current conditions and configures these parameters in the second stage assembly. For example, the controller can calculate the optimal pulse voltage based on a pre-configured first formula, which is:

[0055] Where V represents the optimal pulse voltage; The first resistivity is represented by k; k and b are relevant constants determined based on the properties or type of the target product. For example, when the target product is a graphene precursor, k = 1.2 and b = 0.8 are set.

[0056] Step 202: The controller obtains the first actual position and controls the transfer component to transfer the reaction vessel from the first actual position to the target position.

[0057] The positioning component measures the position of the reaction vessel on the first worktable assembly so that the controller can determine the first actual position of the reaction vessel. The controller then controls the gripping mechanism of the transfer assembly to move to the first actual position to grip the reaction vessel, and controls the transfer assembly to place the reaction vessel at the target position based on the target position pre-configured in the controller on the second worktable assembly.

[0058] Step 203: The controller controls the second workbench assembly to clamp the reaction vessel and heat the reaction vessel according to the heating parameters.

[0059] Specifically, the controller can control the heating electrodes to clamp the reaction vessel, and then control the power supply to discharge to the heating electrodes according to the determined heating parameters to heat the reaction vessel.

[0060] Furthermore, the second workbench assembly also has a temperature monitoring function. During the process of heating the reaction vessel, the second workbench assembly can acquire real-time temperature data of the reactants in the reaction vessel and send the acquired real-time temperature data to the controller. The controller can store the real-time temperature data so that the staff can have a reliable basis for subsequent analysis of the heating temperature of the target material.

[0061] Step 204: Based on the condition that the heating is completed, the controller controls the second workbench assembly to release the clamp on the reaction vessel and controls the transfer assembly to move the reaction vessel out of the plane of the second workbench.

[0062] Once the controller determines that the second workbench assembly has completed heating the reaction vessel, the controller controls the heating electrodes to release their grip on the reaction vessel, and then controls the transfer assembly to re-grip the reaction vessel and transfer it to the unloading area outside the second workbench.

[0063] Thus, the control method of the flash Joule heating device provided in another embodiment of this application achieves coordinated control of the process flow for preparing the target material through a controller, effectively improving the intelligence, adaptability, and repeatability of the flash Joule heating process. Specifically, the controller automatically calculates and configures the optimal heating parameters based on the actual first resistivity of the reactants using a pre-configured formula, avoiding the uncertainty of manual experience-based settings. This allows the heating conditions to dynamically match the resistivity of the reactants, ensuring that different batches of reactants receive appropriate heat treatment intensities. The combination of the positioning component and the transfer component enables precise transfer and automatic clamping of the reaction vessel from the first workbench to the target position on the second workbench, reducing alignment errors and operational risks. In summary, this control method not only improves production efficiency and product consistency but also enhances the device's adaptability to various material systems and provides strong data support for traceability and parameter optimization in the preparation process of the target product.

[0064] In some embodiments, please refer to Figure 3 Step 202 can be achieved through steps 2021 to 2023: Step 2021: The controller acquires a position image of the reaction vessel within the first worktable plane to determine the initial position. The controller then controls the positioning component to emit a laser toward the initial position to determine the first actual position.

[0065] The controller acquires a position image of the reaction vessel within the first worktable plane, captured by the image acquisition element in the positioning component. Based on this image, it determines the relative position between the reaction vessel and the positioning component. Then, it controls the laser emitting element in the positioning component to emit a laser beam towards the reaction vessel to determine a first distance between the positioning component and the reaction vessel. A spatial Cartesian coordinate system is pre-built in the controller, and the relative positions of the positioning component, the first worktable, the second worktable, and the positioning component are set within this system. Based on the relative position between the reaction vessel and the positioning component and the first distance, the controller can calculate the specific coordinates of the reaction vessel; the first actual position is this coordinate value.

[0066] In step 2022, the controller controls the transfer assembly to clamp the reaction vessel based on the first actual position, and transfers the reaction vessel to the plane of the second workbench assembly based on the target position.

[0067] The controller controls the gripping part of the transfer assembly to move to the first actual position and grip the reaction vessel based on the determined first actual position. Then, the controller can determine the optimal transfer route based on the first actual position and the target position, and control the transfer assembly to transfer the reaction vessel to the second worktable according to the transfer route.

[0068] In step 2023, the controller obtains the second actual position of the reaction vessel in the second workbench assembly and compares the second actual position with the target position to determine the position error. Based on the position error being lower than the pre-configured position error threshold, the controller controls the transfer assembly to release the clamp on the reaction vessel.

[0069] After placing the reaction vessel on the second worktable, the controller fine-tunes its position, so the transfer assembly does not immediately release its grip on the reaction vessel. Specifically, the controller acquires the position information of the reaction vessel on the second worktable from the positioning calibration element in the positioning assembly, processes it to determine the reaction vessel's second actual position, which is also a coordinate value. The controller compares the second actual position with the pre-configured target position in the controller to determine the deviation between the reaction vessel's second actual position and the target position. Then, based on this positional deviation, the controller controls the transfer assembly to perform a secondary adjustment of the reaction vessel's position to ensure that the reaction vessel's actual position is consistent with the target position.

[0070] The above embodiments effectively compensate for the accumulated errors of mechanical transport and visual positioning by dividing the transfer process of the reaction vessel into two stages: transfer and fine-tuning. This ensures that the placement of the reaction vessel on the second workbench is accurately aligned with the heating electrode, thereby reducing the risk of poor contact or uneven heating caused by positional deviation. This provides a guarantee for the stability and safety of the reaction vessel during subsequent heating.

[0071] In some embodiments, the heating parameters include a first heating time and electrical parameters. The heating completion condition is met when the second stage assembly heats the reaction vessel according to the electrical parameters, and the actual heating time of the second stage assembly reaches the first heating time.

[0072] For example, the electrical parameters may include pulse voltage, pulse width, etc., and the first heating time and electrical parameters are determined according to the actual situation of the reactants. After the controller determines the heating parameters and configures them to the power supply of the second stage assembly, especially the power supply in the second stage assembly, when the power supply starts to work based on the heating parameters, the controller can monitor the working time of the power supply and the electrical parameters output by the power supply in real time. When the power supply heats the reaction vessel using the heating electrodes according to the determined electrical parameters, and the actual heating time reaches the determined first heating time, the controller immediately controls the power supply to stop working, at which point the heating is complete.

[0073] During the heating process, the controller monitors the power supply's output electrical parameters and operating time in real time to ensure that the actual heating conditions are strictly consistent with the heating parameters calculated based on the reactants' first resistivity. This avoids process failures such as overheating or underheating caused by parameter drift or time deviation. When the power supply's output electrical parameters and operating time meet the standards, the controller immediately and automatically terminates the heating. This ensures that each batch of reactants can be synthesized under optimal thermal history conditions, improving the consistency of the target product's quality. It also enhances the accuracy, controllability, and repeatability of the flash Joule heating process and provides reliable quantitative data for subsequent process optimization and fault tracing.

[0076] In some embodiments, the transfer control module 402 is specifically used to acquire a position image of the reaction vessel in the first workbench plane to determine an initial position, and control the positioning component to emit a laser toward the initial position to determine a first actual position. The transfer control module 402 is also used to control the transfer component to clamp the reaction vessel based on the first actual position, and to transfer the reaction vessel to the second workbench plane based on the target position; The transfer control module 402 is also used to obtain the second actual position of the reaction vessel transferred to the second workbench assembly, compare the second actual position with the target position to determine the position error, and control the transfer assembly to release the clamping of the reaction vessel based on the position error being lower than the pre-configured position error threshold.

[0077] In some embodiments, the heating parameters include a first heating time and a first pulse voltage, and the heating completion condition is met: the second stage assembly heats the reaction vessel according to the first pulse voltage, and the actual heating time of the second stage assembly reaches the first heating time.
