Description

Technical Field

[0001] The present application relates to the field of lithium battery technology, and more specifically, to a stirring device control method, device, storage medium, and electronic device. Background Art

[0002] Battery slurry preparation is the first step in lithium-ion battery production, and its importance is self-evident. Stirring and mixing are key to the lithium battery slurry preparation process, requiring a mixer. Currently, during the slurry preparation process, the dispersing synchronous belt of the mixer is prone to wear and even breakage, resulting in uneven slurry dispersion. Summary of the Invention

[0003] In view of the above problems, the present application provides a stirring equipment control method, device, storage medium and electronic equipment, which can solve the problem of uneven slurry dispersion caused by wear or breakage of the dispersion synchronous belt during the stirring process.

[0004] In the first aspect, the present application provides a method for controlling a stirring device, comprising: when the stirring device starts a dispersion process and the current speed is greater than or equal to the set speed, monitoring the real-time current value of the dispersion motor of the stirring device; when it is determined according to the real-time current value that the stirring device meets the shutdown condition, controlling the stirring device to alarm and shut down.

[0005] In the above implementation process, when the mixing device starts the dispersion process and the current speed of the mixing device reaches or exceeds the set speed, the real-time current value of the dispersion motor is monitored. Then, based on this real-time current value, it is determined whether the mixing device meets the shutdown conditions. If so, the mixing device is controlled to alarm and shut down. In this way, by monitoring the real-time current value of the dispersion motor, the status of the dispersion timing belt can be identified. When an abnormal state is identified, the equipment is promptly controlled to alarm and shut down, thereby effectively solving the problem of uneven slurry dispersion caused by wear or breakage of the dispersion timing belt during the mixing process.

[0006] In some embodiments, whether the stirring device meets the shutdown condition is determined based on the following method: when the real-time current value is less than the target current value, it is determined that the stirring device meets the shutdown condition; the target current value is set based on the current range of the dispersion motor when the dispersion synchronous belt of the stirring device is worn.

[0007] In the above implementation process, a high-speed dispersion current minimum value is set according to the current range of the dispersion motor when the dispersion synchronous belt is worn, so as to set the automatic shutdown condition of the mixing equipment. In this way, the problem of uneven slurry dispersion caused by wear or breakage of the dispersion synchronous belt during the slurry making process of the mixer is effectively solved.

[0008] In some embodiments, the target current value is set according to a target current range; the target current range includes the normal operating current range of the dispersion motor when the stirring equipment produces different types of slurries and the speed is greater than or equal to the set speed, and the wear current range of the dispersion synchronous belt.

[0009] In the above implementation process, a method for determining the target current value is provided, that is, the target current value is set based on the current range of the dispersion motor when it is operating normally and the current range of the dispersion synchronous belt when the dispersion equipment produces different types of slurries and the speed is greater than or equal to the set speed. In this way, the risk of uneven slurry dispersion is effectively reduced while ensuring production efficiency.

[0010] In some embodiments, when the stirring device is an anode stirrer, the target current value is any current value between 60A and 65A; when the stirring device is a cathode stirrer, the target current value is any current value between 80A and 85A.

[0011] In the above implementation process, an optional setting value of the target current value is provided.

[0012] In some embodiments, whether the stirring device meets the shutdown condition is also determined based on the following method: obtaining the current change rate according to the real-time current value; when the current change rate is greater than the target change rate, determining that the stirring device meets the shutdown condition.

[0013] In the above implementation process, the current change rate greater than the target change rate is also set as a shutdown condition. By monitoring the current change rate of the distributed motor, the current mutation state of the distributed motor is identified, thereby more accurately monitoring the abnormal state of the distributed synchronous belt.

[0014] In some embodiments, monitoring the real-time current value of the dispersion motor of the stirring device includes: periodically collecting the real-time current value of the dispersion motor of the stirring device.

[0015] In the above implementation process, the real-time current value of the decentralized motor is collected according to a preset period. In this way, the operator can adjust the sampling frequency according to the needs of the specific scenario to balance the monitoring accuracy and system resources.

[0016] In some embodiments, obtaining the current change rate based on the real-time current value includes: obtaining a preset number of sampling values before the real-time current value collected this time, calculating the average value of the obtained sampling values; and determining the difference between the real-time current value collected this time and the average value as the current current change rate.

[0017] In the above implementation process, a sampling method is used to obtain the average value of the instantaneous current N times before the real-time current value collected this time. The real-time current value is then compared with the average value, and the calculated difference can be determined as the current current change rate, thereby reducing the probability of false alarms of the equipment.

[0018] In some embodiments, the target change rate is determined based on the upper and lower fluctuation values of the current when the stirring device operates normally.

[0019] In the above implementation process, the target change rate is determined according to the upper and lower fluctuation values of the current during normal operation of the equipment. In this way, the abnormal state of the dispersed synchronous belt is accurately identified, and the accuracy of the equipment alarm is improved.

[0020] In the second aspect, the present application provides a stirring equipment control device, including: a monitoring module for monitoring the real-time current value of the dispersion motor of the stirring equipment when the stirring equipment starts the dispersion process and the current speed is greater than or equal to the set speed; a control module for controlling the stirring equipment to alarm and shut down when it is determined that the stirring equipment meets the shutdown conditions based on the real-time current value.

[0021] In a third aspect, the present application provides an electronic device comprising: a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein when the processor executes the computer program, the steps of the method described in any one of the first aspects are implemented.

[0022] In a fourth aspect, the present application provides a computer-readable storage medium having instructions stored thereon. When the instructions are executed on a computer, the computer is caused to execute the method as described in any one of the first aspects.

[0031] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0032] It should be noted that similar reference numerals and letters represent similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings. At the same time, in the description of this application, the terms "first", "second", etc. are only used to distinguish the description and should not be understood as indicating or implying relative importance.

[0033] In the production of lithium-ion batteries, the first step is to evenly mix the positive and negative solid-state battery materials, add a solvent, and stir them into a slurry using a blender. In the positive and negative electrode slurries, the dispersion and uniformity of the granular active material directly affect the movement of lithium ions between the two poles of the battery. Therefore, the mixing and dispersion of the slurries of each electrode material is crucial in the production of lithium-ion batteries. The quality of the slurry dispersion directly affects the quality of subsequent lithium-ion battery production and the performance of its products. The dispersion timing belt is a transmission mechanism in the blender that can transmit the power generated by the dispersion motor to the dispersion shaft, thereby driving the operation of the blender's dispersion impeller. Currently, during the blending process of the blender, the dispersion timing belt of the blender is prone to wear and even breakage, resulting in uneven dispersion of the slurry.

[0034] To address the above technical issues, an embodiment of the present application provides a method for controlling a mixing device. When the mixing device starts the dispersion process and the current speed of the mixing device reaches or exceeds a set speed, the method monitors the real-time current value of the dispersion motor. Based on this real-time current value, the method determines whether the mixing device meets the shutdown conditions. If so, the method controls the device to alarm and shut down. In this way, by monitoring the real-time current value of the dispersion motor, the state of the dispersion timing belt can be identified. When an abnormal state is identified, the device is promptly controlled to alarm and shut down, thereby effectively reducing the risk of uneven slurry dispersion.

[0035] Next, the embodiments of the present application are introduced:

[0036] like Figure 1 As shown, Figure 1 This is a flow chart of a stirring device control method provided in an embodiment of the present application, which can be applied to the control system of the stirring device.

[0037] The method comprises:

[0038] Step 101: When a stirring device starts a dispersion process and the current speed is greater than or equal to a set speed, monitor the real-time current value of the dispersion motor of the stirring device;

[0039] The primary purpose of the lithium battery slurrying process is to evenly disperse active materials, conductive agents, binders, and other substances to obtain a uniform, stable slurry for electrode coating. After the required materials are added to the mixing equipment, the mixing equipment can start the dispersion process and operate according to the set PLC (Programmable Logic Controller) program to ensure the uniform dispersion of the materials.

[0040] In this embodiment, when dispersion is activated and the stirring device's speed is greater than or equal to the set speed, indicating that the stirring device is in the high-speed dispersion stage, the real-time current value of the dispersion motor is monitored to identify the presence of a broken synchronous belt or mechanical wear within the stirring device's transmission case. This can be achieved by embedding a dispersion current change monitoring module in the stirring device's PLC program to monitor the real-time current value of the dispersion motor.

[0041] The set speed can be set according to the electrode material corresponding to the stirring device and the corresponding high-speed dispersion speed. Generally speaking, a stirring device only produces slurry of one electrode material, that is, the anode mixer produces the negative electrode slurry, and the cathode mixer produces the positive electrode slurry. The negative electrode process high-speed dispersion speed of the anode mixer is usually higher than 1000 rpm, and the positive electrode process high-speed dispersion speed of the cathode mixer is usually higher than 600 rpm. Therefore, when the stirring device is an anode mixer, the set speed can be 1000 rpm, and when the stirring device is a cathode mixer, the set speed can be 600 rpm.

[0042] Step 102: When it is determined according to the real-time current value that the stirring device meets the shutdown condition, the stirring device is controlled to alarm and shut down.

[0043] When the real-time current value determines that the mixing equipment meets the shutdown conditions, it means that the dispersion motor current has suddenly changed. At this time, the dispersion synchronous belt may be in an abnormal state of mechanical wear or even belt breakage. Therefore, the mixing equipment is controlled to output an alarm signal and stop operation to prevent the mixing equipment from continuing to work and causing uneven slurry dispersion.

[0044] In some embodiments, whether the stirring device meets the shutdown condition can be determined based on the following method: when the real-time current value is less than the target current value, it is determined that the stirring device meets the shutdown condition; the target current value is set based on the current range of the dispersion motor when the dispersion synchronous belt of the stirring device is worn. In other words, a minimum high-speed dispersion current value, i.e., the target current value, is set based on the current range of the dispersion motor when the dispersion synchronous belt is worn, and the automatic shutdown condition of the stirring device is set accordingly. That is, when the real-time current value of the dispersion motor is less than the minimum high-speed dispersion current value, it is determined that the stirring device meets the shutdown condition, and then the device is controlled to alarm and shut down. In this way, the problem of uneven slurry dispersion caused by wear or breakage of the dispersion synchronous belt during the slurrying process of the stirring machine is effectively solved.

[0045] Furthermore, the aforementioned target current value can be set based on a target current range; this target current range includes the normal operating current range of the dispersion motor when the mixing equipment is producing different types of slurries and the speed is greater than or equal to the set speed, as well as the current range of the dispersion belt wear. That is, during implementation, the current changes of the dispersion motor when the mixing equipment is producing different types of slurries and the speed is greater than or equal to the set speed can be collected to generate a dispersion current curve. In this dispersion current curve, the current range during normal operation and the current range when the dispersion belt mechanically wears can be distinguished, thereby setting an appropriate minimum high-speed dispersion current. For example, when an anode mixer produces different types of slurries and the speed reaches above 1000 rpm, the current range of the dispersion motor during normal operation is 70A to 110A, but when the dispersion belt wears, the current of the dispersion motor is less than 50A. Therefore, the target current value used as the shutdown condition can be set based on these two current ranges. Compared with setting the target current value based solely on the current range of the dispersion motor when the dispersion belt wears, the resulting target current value is more accurate and reasonable, thereby effectively reducing the risk of uneven slurry dispersion while ensuring production efficiency.

[0046] Optionally, when the stirring device is an anode stirrer, the target current value can be any current value between 60 A and 65 A; when the stirring device is a cathode stirrer, the target current value can be any current value between 80 A and 85 A. Experiments have shown that this setting can accurately identify abnormal conditions of the dispersion timing belt during the slurry production process of the stirrer, thereby effectively ensuring the uniformity of slurry dispersion.

[0047] In addition, in some embodiments, whether the stirring device meets the shutdown condition can also be determined based on the following method: the current change rate is obtained according to the real-time current value; when the current change rate is greater than the target change rate, it is determined that the stirring device meets the shutdown condition. That is to say, in addition to the shutdown condition when the current change rate is greater than the target change rate, the current change rate greater than the target change rate can also be set as another shutdown condition, that is, when the current change rate is greater than the target change rate, or the current change rate is greater than the target change rate, it is determined that the stirring device meets the shutdown condition, and the stirring device is controlled to alarm and shut down. The current change rate here can refer to the change in the real-time current value of the dispersed motor per unit time. By monitoring the current change rate of the dispersed motor, the current mutation state of the dispersed motor can be identified, thereby realizing the identification of the abnormal state of the dispersed synchronous belt wear or breakage. In this way, the monitoring of the abnormal state of the dispersed synchronous belt can be achieved more accurately.

[0048] Furthermore, in some embodiments, the aforementioned monitoring of the real-time current value of the dispersed motor of the stirring device may include: periodically collecting the real-time current value of the dispersed motor of the stirring device. In other words, a suitable collection period can be set according to actual needs, and the system collects the real-time current value of the dispersed motor according to the collection period. In this way, the operator can adjust the sampling frequency according to the needs of the specific scenario to balance the monitoring accuracy and system resources. Accordingly, the aforementioned acquisition of the current change rate based on the real-time current value may include: obtaining a preset number of sampling values before the real-time current value collected this time, calculating the average value of the obtained sampling values; and determining the difference between the real-time current value collected this time and the average value as the current current change rate. In other words, a sampling method is used to obtain the average value of the instantaneous currents N times before the current real-time current value is collected. This real-time current value is then compared with this average value, and the difference calculated can be used to determine the current current rate of change. For example, if N = 3, and the current real-time current value is 76A, and the previous three real-time current values were 75A, 73A, and 71A, respectively, the calculated average value is 73A. The difference between the current real-time current value and this average value is 3A, so the current current rate of change can be expressed as 3A. In this way, through a scientific sampling method, the probability of false alarms can be reduced.

[0049] Furthermore, the target rate of change can be considered the upper limit of the current rate of change of the dispersed motor, and the target rate of change can be determined based on the current fluctuations during normal operation of the mixing equipment. In other words, when setting the target rate of change as a shutdown condition, it can be determined based on the current fluctuations during normal operation of the equipment. For example, if the current fluctuations during normal operation of the mixing equipment are 2A, the target rate of change can be set to any value between 2.4A and 2.6A. In this way, abnormal conditions of the dispersed synchronous belt can be accurately identified, improving the accuracy of equipment alarms.

[0050] In an embodiment of the present application, when the agitator starts the dispersion process and the current speed of the agitator reaches or exceeds a set speed, the real-time current value of the dispersion motor is monitored. Based on this real-time current value, it is determined whether the agitator meets the shutdown conditions. If so, the agitator is controlled to shut down with an alarm. Thus, by monitoring the real-time current value of the dispersion motor, the state of the dispersion timing belt can be identified. When an abnormal state is identified, the equipment is promptly controlled to shut down with an alarm, thereby effectively solving the problem of uneven slurry dispersion caused by wear or breakage of the dispersion timing belt during the agitator's slurrying process.

[0051] In order to explain the solution of this application in more detail, a specific embodiment is introduced below:

[0052] This embodiment provides a detection scheme for wear and breakage of the dispersed synchronous belt of the mixer. The working process of the scheme is as follows: Figure 2 Shown, including:

[0053] S201, decentralized start;

[0054] S202, the mixer speed reaches the set speed;

[0055] S203, continuously monitoring and sampling the current of the dispersed motor;

[0056] Among them, by embedding the dispersed current change monitoring module in the mixer PLC program, the current of the dispersed motor is continuously monitored;

[0057] S204, determining whether the monitored current is less than a preset minimum current value, if yes, executing S208, otherwise executing S205;

[0058] The minimum current value can be set based on the current range of the dispersion motor when the dispersion synchronous belt is mechanically worn. For example, when the anode mixer produces different types of slurries and the speed reaches 1000 rpm or above, the dispersion current of the dispersion motor is in the range of 70A to 110A. When the dispersion synchronous belt is worn, the current of the dispersion motor is lower than 50A. Therefore, by programming the PLC and touch screen, the minimum current value of the anode mixer in the high-speed dispersion stage can be set to 60A.

[0059] S205, calculating the average value of the current monitored for the previous N times;

[0060] S206, calculating the difference between the monitored current and the average value, and determining the difference as the current current change rate;

[0061] S207, determine whether the current change rate is greater than a preset maximum change rate, if yes, execute S208, otherwise return to 203;

[0062] The maximum rate of change can be obtained by multiplying the current fluctuation value during normal operation of the device by 1.2.

[0063] S208. Control the equipment to alarm and shut down.

[0064] This embodiment solves the problem of the mixing equipment's dispersing synchronous belt breaking and the inability to monitor abnormal mechanical wear, thereby avoiding the problem of uneven slurry dispersion.
