In a specific application, the control module may be preset with a standard curve or calibration data, and according to the temperature of the slurry (semi-solid slurry) and the slurry container 900, it may optimize the heating parameters of the heating component 200 according to the temperature.

[0040] Specifically, the feeding component includes a first driving component for driving the crystal nucleus generating device 310 to rotate or linearly move to the top of the slurry container 900 at the heating station 101. In this embodiment, the first driving component can be a motor component, such as a rotary motor or a linear motor, etc. When the crystal nucleus generating device 310 is not needed, the crystal nucleus generating device 310 can be left from the heating station 101 and cooled for the next use.

[0041] Specifically, the crystal nucleus generating device 310 is a funnel, which can be a metal part, which is conducive to quenching the slurry.

[0042] Specifically, the heating component 200 is arranged on the side or / and the bottom of the heating station 101. The heating station 101 is provided with a lifting driving component 510 for driving the slurry container 900 to rise and fall. After heating is completed, the lifting driving component 510 can lift the slurry container 900 so that the robot arm component 610 (robot) can pour the container in the slurry container 900 into the molding device. The molding device can clamp the slurry container 900 and transfer it to the molding device (die casting machine, extrusion casting machine, hydraulic press, etc.), and pour the slurry in the container into the barrel of the molding device for molding.

[0043] Specifically, the heating component 200 is an electromagnetic heating device, and the electromagnetic heating device forms an annular cavity for inserting the slurry container 900. The electromagnetic heating device may include one or more groups of electromagnetic heating coils arranged up and down. The heating station 101 is a sink structure, and the electromagnetic heating device is arranged in the sink structure, and the temperature of the slurry container 900 is not easily affected by the external environment. In specific applications, an insulation layer may also be optionally provided in the sink structure. The slurry container 900 may be a cylindrical container with an open top, and its outer diameter may be in a suitable size range such as 70 mm, and its height may be in a suitable size range such as 200 mm.

[0044] Specifically, the temperature sensing component includes an internal temperature sensing device (which may be an internal temperature measuring thermocouple 710) for detecting the internal temperature of the slurry when the heating component 200 heats the slurry; the temperature sensing component includes an external temperature sensing device (which may be an external temperature measuring thermocouple 720) for detecting the temperature outside the slurry container 900, and the external temperature measuring thermocouple 720 may be attached to the outer surface of the slurry container 900. There are one or more external temperature measuring thermocouples 720, and when there are multiple external temperature measuring thermocouples 720, they may be arranged along the circumference of the outer surface of the slurry container 900 and arranged in an upper and lower staggered manner, so that the temperature of the outer surface of the slurry container 900 can be measured more accurately, so as to more accurately predict the temperature inside the slurry container 900. One or more internal temperature measuring thermocouples 710 may be provided. When multiple internal temperature measuring thermocouples 710 are provided, they may be arranged at intervals, and the internal temperature measuring thermocouples 710 may be arranged at different heights (up and down offset) to better detect the temperatures at different positions and depths inside the slurry, thereby better adjusting the parameters of the heating component 200 according to the temperature conditions, such as adjusting the power and heating time of different electromagnetic heating devices.

[0045] Specifically, the fully automatic rapid preparation device also includes a material moving component 620 for moving the slurry in the slurry container 900 to the molding device, and the material moving component 620 can be a robot (robotic arm).

[0046] Specifically, the workbench 100 is provided with a container placement station (a first station 102 and a second station 103) for placing the slurry container 900, and the workbench 100 is also provided with a cleaning and drying component 104 and a touch screen controller 150 for cleaning and drying the slurry container 900; the fully automatic rapid preparation device also includes a mechanical arm component 610 for moving the slurry container 900 to the container placement station, the cleaning and drying component 104 and the heating station 101. The mechanical arm component 610 (manipulator) is equipped with a gripper to grip the slurry container 900, and the movement of the mechanical arm enables other components to cooperate with each other.

[0047] In this embodiment, the container placement station includes a first station 102 and a second station 103, and the first station 102, the second station 103 and the third station are arranged adjacent to each other in sequence. The cleaning and drying component 104 is located on one side of the first station 102 or the second station 103. The cleaning and drying component 104 may have a high-pressure dry air nozzle 140, and the robot arm component 610 turns the slurry container 900 to be used upside down on the high-pressure dry air nozzle 140, and uses high-pressure dry air to cool and clean the inner surface of the slurry container 900, and fully removes impurities such as water vapor on the inner surface of the slurry container 900.

[0048] The embodiment of the present invention further provides a method for fully automatic and rapid preparation of a semi-solid alloy slurry, using the above-mentioned fully automatic and rapid preparation device for a semi-solid alloy slurry, comprising the following steps:

[0049] The robot arm component 610 moves the slurry container 900 to the heating station 101;

[0050] The crystal nucleus generating device 310 is moved above the slurry container 900;

[0051] The material taking component 410 pours or injects the slurry into the crystal nucleus generating device 310;

[0052] The slurry generates crystal nuclei under the quenching effect of the crystal nucleus generating device 310, and the crystal nuclei are dispersed inside the slurry melt under the effect of the slurry flow;

[0053] The slurry flows into the slurry container 900 to form a semi-solid slurry;

[0054] The temperature sensing component detects the temperature of the semi-solid slurry and the slurry container 900;

[0055] The heating component 200 heats the slurry container 900;

[0056] The control module controls the heating parameters of the heating member 200 according to the temperatures of the semi-solid slurry and the slurry container 900 .

[0057] Specifically, the preparation step includes a slurry parameter automatic identification step:

[0058] The temperature sensing component collects the slurry temperature and the slurry container 900 temperature data and transmits them to the control module. The control module transmits the signal to the heating component 200 after calculation to control the heating power of the heating component 200.

[0059] In specific applications, the crystal nucleus generating device 310 (funnel) is installed on one side of the heating station 101, which can quickly cool the aluminum alloy melt to form a large number of crystal nuclei, and make the melt (slurry) flow into the slurry container 900, and the funnel can rotate around the rotating shaft. The electromagnetic heating device (electromagnetic induction heating coil) is installed in the heating station 101, and the semi-solid slurry container 900 is quickly heated using the electromagnetic induction heating coil to make the slurry temperature field uniform. The lifting drive component 510 (container lifting device) is installed below the heating station 101 to control the lifting and exit of the slurry container 900 in and out of the electromagnetic induction heating coil. The cooling and cleaning device is installed in the cooling station, which can cool and clean the inner surface of the slurry container 900 to be used by spraying high-pressure dry air, and fully remove the water vapor on the inner surface. The slurry container 900 mainly serves to carry the slurry and can be made of metal materials such as stainless steel and titanium alloy. The internal temperature measuring bracket 711 is installed beside the funnel. The funnel and the internal temperature measuring bracket 711 can be fixedly connected to the rotating member 712. The rotating member 712 can rotate around the rotating shaft on the workbench. The funnel and the internal temperature measuring bracket 711 can be set at intervals of a set angle (90 degrees). The internal temperature measuring thermocouple 710 can be connected to the internal temperature measuring bracket 711. The internal temperature measuring bracket 711 can be raised and lowered. In specific applications, an electric lifting structure can be used to drive the internal temperature measuring bracket 711. The internal temperature measuring thermocouple 710 can be inserted into the slurry to measure the internal temperature of the slurry to provide data for data acquisition and system correction. The external temperature measuring bracket 721 is installed on the container lifting device. The external temperature measuring thermocouple 720 is installed on the external temperature measuring bracket 721. The external temperature sensing device can measure the surface temperature of the slurry container 900 through the external temperature measuring thermocouple 720 installed thereon, so as to realize accurate monitoring of the temperature field of the pile slurry during the production process without polluting the slurry. In practical applications, many key parameters are difficult to obtain accurate values ​​through direct measurement. For example, the uncertainty of the temperature-dependent parameters such as the heat transfer coefficient of the inner wall of the slurry container 900 and the heat flux density outside the slurry container 900 may affect the accuracy of the control and the effectiveness of the control strategy. Therefore, it is necessary to measure the temperature during the actual production process. The data recorded by the temperature sensing components (external temperature measuring thermocouple 720 and internal temperature measuring thermocouple 710) can be used for parameter identification to improve the practicality of the model and the accuracy of the prediction, that is, to estimate those parameters that are not easy to measure by extracting information from the system response.

[0060] In the parameter identification problem method, the Levenberg-Marquardt method can be used as a gradient-based optimization method. The specific steps are as follows:

[0061] A mathematical model is established, and the system equation of the one-dimensional nonlinear heat transfer model obtained by the finite difference method is used as the basic model:

[0062]

[0063] Error definition: Define an error function to measure the difference between the model output and the actual system output, usually in the form of squared error. The error can be expressed as:

[0064] S(θ)=(T meas -T cal (θ) T (T meas -T cal (θ)

[0065] Minimize error: The goal is to find the parameter θ so that the sum of square errors between the output predicted by the model and the actual output is minimized, so as to accurately identify the system equation parameters. The specific process of automatic identification of slurry parameters is as follows: Figure 6 , starting from the initial parameter value, set the initial value of the optimization process; then through the formula θ new =θ+(J T J+λ·diag(J T )) -1 J T e calculates the new parameters, where J is the Jacobian matrix, λ is the adjustment parameter used to control the step size, and e is the error vector; the next step is to calculate the error s(θ) = (T meas -T cal (e)) T (T meas -T cal (θ)), if S(θ) changes greatly (that is, the current error is still large), increase the λ value: λ = 2λ, and return to step 2 to recalculate the new parameters. If S(θ) changes slightly, reduce the λ value: λ = 0.5λ, and update the current parameters; finally, determine whether S(θ) is less than a certain threshold δ. If so, it indicates that the algorithm has converged and returns the final parameter value. If not, return to step 2 to continue iterating. This adjustment is achieved by introducing an adjustment factor λ. The size of λ is dynamically adjusted according to the change of the error function during the iteration process. Through such regulation, the LM algorithm not only ensures the stability of convergence, but also accelerates the convergence speed.

[0066] In specific applications, the system may first perform the slurry parameter automatic identification step when it is first run. At the beginning, the slurry container 900 is placed on the lifting drive component 510 and descends into the electromagnetic induction heating coil, and the funnel rotates to the top of the heating station 101. The material taking component 410 (scooping mechanism) scoops a fixed amount of aluminum alloy melt (slurry) from the aluminum alloy melting furnace, and then moves to the heating station 101 and pours it. At this time, the aluminum alloy melt (slurry) will contact the cooling funnel. Due to the chilling effect of the funnel, a large number of crystal nuclei are generated in the aluminum alloy melt (slurry). As the aluminum alloy melt (slurry) further flows, the formed crystal nuclei are dispersed to various positions inside the aluminum alloy melt (slurry). The aluminum alloy melt flowing from the funnel into the slurry container 900 is further cooled due to the heat transfer to the slurry container 900 and the air with a lower temperature, and changes from liquid to semi-solid. After the pouring is completed, the cooling funnel is rotated and removed, and the internal temperature measuring bracket 711 is rotated to the top of the slurry container 900 at the same time. At the same time, the internal temperature measuring thermocouple 710 can be inserted into the slurry. Then the heating component 200 (electromagnetic induction heating coil) is started to heat and adjust the temperature of the slurry in the slurry container 900. During this process, the internal temperature measuring thermocouple 710 and the external temperature measuring thermocouple 720 simultaneously collect data and transmit it to the control module (controller). After calculation, the controller transmits the signal to the heating component 200 (electromagnetic induction heating coil), accurately controls the heating power and / or heating time of the heating component 200 (electromagnetic induction heating coil), ensures that the slurry is heated to the specified temperature and ensures the uniformity of the internal temperature field; at the same time, the collected temperature data is stored in the controller, and the Levenberg-Marquardt method is used for system identification, and the control model is automatically optimized. Finally, the data is displayed on the touch screen controller 150 of the workbench 100. After completion, the internal temperature measuring bracket 711 is reset. The lifting drive component 510 rises, and the robotic arm 620 takes away the slurry container 900 that is lifted out of the heating station 101.

[0067] After completing the parameter identification, the automatic production process can be started. At the beginning, the slurry container 900 is placed on the lifting drive component 510 and descends into the electromagnetic induction heating coil, and the funnel rotates to the top of the heating station 101. The scooping mechanism scoops a certain amount of aluminum alloy melt from the aluminum alloy melting furnace, and then moves to the heating station 101 and pours it. At this time, the molten aluminum alloy will contact the cooled funnel. Due to the chilling effect of the funnel, a large number of crystal nuclei are generated in the melt. As the metal melt continues to flow, the formed crystal nuclei are dispersed to various positions inside the melt. The aluminum alloy melt flowing into the slurry container 900 is further cooled due to the heat transfer to the container and air with lower temperature, and changes from liquid to semi-solid. After the scooping mechanism completes pouring, the cooling funnel rotates and moves away, and the electromagnetic induction heating coil begins to heat the slurry container 900. At the same time, an external temperature measuring thermocouple 720 is used to collect data and transmit it to the controller for closed-loop control. The heating power of the induction coil is accurately controlled to reduce the temperature difference from the edge to the center of the slurry, increase the uniformity of the slurry temperature field, and promote the growth of grains in a non-dendritic manner to complete slurrying.

[0068] After the slurry is made, the lifting drive component 510 lifts the slurry container 900 outside the induction coil. The robot arm grabs the slurry container 900 and transfers it to the molding equipment 990 (die casting machine, extrusion casting machine, hydraulic press, etc.), and pours the slurry in the container into the barrel of the molding equipment 990 for molding. After the robot arm grabs the slurry container 900 on the lifting drive component 510, another robot arm immediately puts the slurry container 900 waiting on the container support on the second station 103 into the lifting drive component 510, and then moves the slurry container 900 on the container support on the first station 102 upside down to the cooling station. The cooling and cleaning device uses high-pressure dry air to cool and clean the inner surface of the slurry container 900, fully removes the water vapor on the inner surface, and then places it on the container support on the second station 103. After the slurry container 900 on the container support on the first station 102 is taken away, the robot arm places the container after pouring on the container support on the first station 102, completing a cycle. In the circulation process, various parameters in the process flow can be monitored in real time through the touch screen controller 150 on the workbench 100, and functions such as precise control of the slurry temperature can be achieved.

[0069] The fully automatic and rapid preparation device and method of alloy semi-solid slurry provided in the embodiment of the present invention can be used as a fully automatic and rapid preparation method of sequential aluminum alloy semi-solid slurry, and adopts a mechanical arm, a lifting drive component 510 and a slurry container 900, etc. to perform aluminum alloy semi-solid slurry preparation operations, realize automatic, continuous, uninterrupted, efficient and automatic circulation to realize metal semi-solid slurrying, and achieve the control law with the shortest working time as the goal under the premise of ensuring the smooth operation of the production line. It can realize the precise control of the slurry temperature during the semi-solid slurrying process, ensure the uniformity of the temperature field inside the slurry, and ensure the stability of the casting quality.
