[0045] Embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although certain embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be construed as being limited to the embodiments described herein, which are instead provided for a more thorough and complete understanding of the present invention. It should be understood that the drawings and embodiments of the present invention are only for exemplary purposes and are not intended to limit the scope of protection of the present invention.

[0046] The working principle of the constant voltage controlled magnetizer is based on charging the energy storage capacitor to a set voltage value, and then using this voltage to drive the magnetizing coil to generate a magnetic field. The strategy focuses on maintaining the stability of the charging voltage, ensuring that the magnetizing effect is controlled by other means (such as adjusting the magnetizing time or coil parameters) under the premise of unchanged voltage. The constant voltage control method simplifies the design of the control system, is easy to achieve standardized production and control, and has relatively low cost. However, when there are multiple channels for magnetization, due to the differences in the coil internal resistance electrical components of each channel, as well as the influence of external factors such as ambient temperature, the magnetizing current of each channel will inevitably be different under constant voltage conditions, making it difficult to accurately control the magnetizing current, and unable to effectively ensure the consistency and repeatability of the magnetizing effect.

[0047] In order to solve the above problems, the embodiment of the present invention provides a magnetization control method, such as Figure 1 As shown, the magnetization control method mainly includes:

[0048] Step S101, in response to the start of a magnetization operation, obtaining current magnetization current values ​​in a plurality of magnetization channels during the magnetization operation.

[0049] Among them, the magnetization control method provided in the embodiment of the present invention is applied to the magnetization control scenario of a multi-channel magnetization device. The multi-channel magnetization device is a device designed to magnetize multiple independent magnetic components simultaneously or sequentially, and is widely used in industrial scenarios that require high efficiency and mass production. Each channel in the multi-channel magnetization device can be controlled independently, allowing magnetic components of different sizes, shapes or requiring different magnetic field strengths to be magnetized at the same time, increasing the diversity of the production line; and multiple channels can work in parallel, shortening the overall processing time, which is suitable for large-scale production needs.

[0050] Based on multiple channels, different magnetic components (i.e., target products) can be magnetized independently. Multiple channels can work in parallel, and different channels may exhibit different current response characteristics due to factors such as material differences and changes in coil impedance. After the magnetization operation is started, the current magnetization current value in each magnetization channel is obtained respectively, and the changes in the magnetization current of each channel can be obtained in time, which is convenient for subsequent control of the consistency of the magnetization current.

[0051] In some of the embodiments, before the step of obtaining current magnetization current values ​​in multiple magnetization channels during the magnetization operation in response to the start of the magnetization operation, the method further includes: obtaining a preset magnetization voltage value, and charging the energy storage module until the voltage value of the energy storage module meets the preset magnetization voltage value; supplying energy to a magnetization device (such as a magnetization coil) through the energy storage module to start the magnetization operation of the magnetization device on the target product.

[0052] By presetting and implementing a specific energy storage module voltage value, it is possible to ensure that there is sufficient energy supply during the magnetization process to achieve the expected magnetic field strength. That is, before the magnetization operation starts, by accurately charging the energy storage module to the preset magnetization voltage value, the risk of overcharging or undercharging can be avoided. At the same time, the pre-charged energy storage module can quickly release energy during magnetization, shortening the time required for magnetization and improving the overall efficiency of the magnetization operation. In the subsequent magnetization process, it is only necessary to adjust the magnetization voltage value in combination with the preset magnetization current value to achieve precise control of the magnetization process on the basis of improving the magnetization efficiency.

[0053] Step S102, determining a target magnetizing voltage value corresponding to each magnetizing channel according to a preset magnetizing current value, a magnetizing channel mapping table and a current magnetizing current value; wherein the magnetizing channel mapping table includes a correspondence between a preset magnetizing current value and a target magnetizing voltage value in each magnetizing channel.

[0054] Among them, the magnetization channel mapping table provided in the embodiment of the present invention realizes presetting of the most suitable magnetization current value-magnetization voltage value correspondence according to the specific physical properties (such as coil resistance, inductance, etc.) and material properties of each channel, so that the magnetization adjustment of each magnetization channel can be optimized in a targeted manner. The target magnetization voltage value corresponding to each magnetization channel is obtained by precise matching, ensuring that when multiple channels work at the same time, even if the conditions of each magnetization channel are different, the magnetization voltage value can be corrected in combination with the magnetization channel mapping table to ensure the consistency of the magnetization current value, thereby improving the magnetization effect.

[0055] In some of the embodiments, the method further includes the step of constructing a magnetization channel mapping table: controlling the magnetization output of a single magnetization channel to be turned on respectively, adjusting the magnetization voltage value corresponding to the magnetization channel and detecting the magnetization current value, and when the detected magnetization current value meets the preset magnetization current value, determining the current magnetization voltage value as the target magnetization voltage value; until the target magnetization voltage values ​​corresponding to all magnetization channels when the preset magnetization current value is met are obtained, and the magnetization channel mapping table is constructed.

[0056] The above steps provide a construction step for a magnetization channel mapping table. Specifically, by testing and recording the corresponding target magnetization voltage value when the preset magnetization current value is reached one by one, an accurate mapping relationship is formed. In actual production, the voltage is set quickly and accurately according to this mapping table, which reduces the trial and error process, directly reaches the preset magnetization state, and improves the accuracy and efficiency of magnetization. The construction of the mapping table provides a data reference for the subsequent adjustment of the target magnetization voltage value, greatly simplifies the magnetization control operation process, reduces the complexity and error rate of manual intervention, and the maintenance and update of the mapping table are relatively simple, which is convenient for optimization according to the adjustment of the magnetization production line or the introduction of new target products.

[0057] In some of the embodiments, the step of determining the target magnetization voltage value according to the preset magnetization current value, the magnetization channel mapping table and the current magnetization current value includes: determining the current difference between the current magnetization current value and the preset magnetization current value, and judging whether the current difference is within a preset threshold range; if the current difference is within the preset threshold range, taking the current magnetization voltage value in the magnetization operation as the target magnetization voltage value; if the current difference is not within the preset threshold range, determining the target magnetization voltage value according to the magnetization channel mapping table and the preset magnetization current value.

[0058] Among them, the setting of the preset threshold range provided by the embodiment of the present invention can be formulated according to the product magnetization requirements. When the current difference between the detected current magnetization current value and the preset magnetization current value is within the preset threshold range, the current magnetization voltage value may not be adjusted, that is, the current magnetization voltage value is the target magnetization voltage value, which avoids unnecessary adjustments and reduces control errors. If the current difference exceeds the preset threshold range, the new target magnetization voltage value can be determined by combining the magnetization channel mapping table, ensuring that when the magnetization current value deviates greatly from the preset current value, it can be corrected in a timely and effective manner, thereby improving the magnetization control accuracy and the stability of the magnetization control system.

[0059] Step S103, performing a magnetization operation on a target product in a corresponding magnetization channel according to a target magnetization voltage value.

[0060] The target product is magnetized by the target magnetization voltage value corresponding to the preset magnetization current value, thereby ensuring the consistency of the magnetization current of different channels, thereby ensuring the consistency of the magnetization magnetic field, improving the magnetization effect and improving the magnetization efficiency and the qualified rate of magnetized products.

[0061] In some of the embodiments, in the step of performing a magnetization operation on a target product in a corresponding magnetization channel according to a target magnetization voltage value, the method further includes: obtaining actual magnetization current values ​​in a plurality of magnetization channels, and determining a current difference between an actual magnetization current value and a preset magnetization current value; if the current difference is not within a preset threshold range, determining a voltage compensation value according to the current difference, and adjusting the target magnetization voltage value according to the voltage compensation value.

[0062] The above method adds a current monitoring and automatic compensation mechanism to the multi-channel magnetization operation. If the magnetization current value deviates from the set range due to changes in ambient temperature, rising coil temperature or other external factors, the necessary voltage compensation value can be calculated through the above steps to adjust the target magnetization voltage value, thereby returning the magnetization current value to the set value range. By obtaining and comparing the actual magnetization current value of each magnetization channel with the preset value in real time, the current inconsistency problem caused by differences between channels (such as coil resistance, temperature changes, etc.) can be discovered and corrected in time, thereby ensuring that the magnetization magnetic field strength of all channels remains highly consistent, thereby improving the magnetic performance consistency of the final product. And the process of automatically adjusting the voltage compensation value is based on the actual detected current deviation. This dynamic feedback control strategy significantly enhances the control accuracy of the magnetization process, enables the system to quickly respond to external interference, maintain the magnetization current value within the preset threshold range, reduce the need for human intervention, improve the level of automation, and also help to improve the magnetization efficiency and magnetization qualification rate.

[0063] The above settings make the magnetization control system more adaptable to environmental changes (such as temperature fluctuations), material batch differences, etc., and can maintain the stability and consistency of the magnetization process through automatic compensation even under non-ideal conditions, thereby improving the system's stable operation capability and scope of application, and further expanding the applicable scenarios of the magnetization control method.

[0064] According to a specific implementation of an embodiment of the present invention, a large amount of actual operation data can be accumulated by continuously detecting and recording the current difference and compensation operation (voltage compensation value) during the magnetization process, so as to provide data support for the subsequent optimization of magnetization parameters and improvement of production processes, and also facilitate the diagnosis and prevention of potential equipment failures.

[0065] In some of the embodiments, the method further includes: obtaining a current magnetic field strength corresponding to the magnetizing device; adjusting a target magnetizing voltage value according to a magnitude relationship between the current magnetic field strength and a preset magnetic field strength, and performing a magnetizing operation according to the adjusted target magnetizing voltage value.

[0066] Based on the above settings, the embodiment of the present invention also provides another magnetization strategy to ensure the consistency of the multi-channel magnetization magnetic field. That is, the target magnetization voltage value is adjusted in combination with the difference between the current magnetic field strength and the preset magnetic field strength of the magnetization device. This magnetization strategy serves as both a separate magnetization control scheme and a supplement to the target magnetization voltage value determined based on the current magnetization current value, the magnetization channel mapping table, and the preset magnetization current value. That is, the magnetization process is controlled by the dual constraints of the magnetization current value and the magnetization magnetic field to ensure the consistency of the magnetization current and magnetization magnetic field of the multi-channel, and to improve the magnetization effect and the magnetization control effect.

[0067] The above-mentioned magnetization control method provided by the embodiment of the present invention adopts the method of obtaining the current magnetization current values ​​in multiple magnetization channels during the magnetization operation in response to the start of the magnetization operation; determining the target magnetization voltage value corresponding to each magnetization channel according to the preset magnetization current value, the magnetization channel mapping table and the current magnetization current value; wherein the magnetization channel mapping table includes the correspondence between the preset magnetization current value and the target magnetization voltage value in each magnetization channel; and performing the magnetization operation of the target product in the corresponding magnetization channel according to the target magnetization voltage value. The technical means overcomes the problem that the magnetization current control effect of the multi-channel magnetization machine in the constant voltage control mode in the related art is poor, it is difficult to ensure the consistency of the magnetic field, and thus leads to low magnetization accuracy and efficiency, and realizes the detection of the current magnetization current value of each magnetization channel, and adjusts the magnetization voltage value in combination with the preset magnetization current value to ensure the consistency of the magnetization current of each channel, thereby ensuring the consistency of the magnetic field of each channel, improving the magnetization current control effect, and improving the technical effect of improving the accuracy of the magnetization operation and the magnetization efficiency.

[0068] Based on the above magnetization control method provided by the embodiment of the present invention, the embodiment of the present invention also provides a magnetization control system, which is applied to the magnetization control scenario of a multi-channel magnetization device, such as Figure 2 As shown, the magnetization control system 200 includes:

[0069] The acquisition unit 201 is used for acquiring current magnetization current values ​​in a plurality of magnetization channels during the magnetization operation in response to the start of the magnetization operation.

[0070] Based on the characteristics that different channels may exhibit different current responses due to factors such as material differences and changes in coil impedance, after the magnetization operation is started, the current magnetization current value in each magnetization channel is obtained respectively, so that the changes in the magnetization current of each channel can be obtained in time, which is convenient for subsequent control of the consistency of the magnetization current.

[0071] The data processing unit 202 is used to determine the target magnetization voltage value corresponding to each magnetization channel according to the preset magnetization current value, the magnetization channel mapping table and the current magnetization current value; wherein the magnetization channel mapping table includes the corresponding relationship between the preset magnetization current value and the target magnetization voltage value in each magnetization channel.

[0072] The target magnetizing voltage value corresponding to each magnetizing channel is obtained by precise matching, ensuring that when multiple channels work at the same time, even if the conditions of each magnetizing channel are different, the magnetizing voltage value can be corrected in combination with the magnetizing channel mapping table to ensure the consistency of the magnetizing current value, thereby improving the magnetizing effect.

[0073] In some of the embodiments, before the step of obtaining current magnetization current values ​​in multiple magnetization channels during the magnetization operation in response to the start of the magnetization operation, the data processing unit 202 is also used to: obtain a preset magnetization voltage value, and charge the energy storage module until the voltage value of the energy storage module meets the preset magnetization voltage value; supply energy to the magnetization device through the energy storage module to start the magnetization operation of the magnetization device on the target product.

[0074] Before the magnetization operation starts, the preset magnetization voltage value is obtained, and the energy storage module is accurately charged to the preset voltage value to avoid the risk of overcharging or undercharging. At the same time, the pre-charged energy storage module can quickly release energy during magnetization, shorten the time required for magnetization, and improve the overall efficiency of the magnetization operation. In the subsequent magnetization process, the magnetization voltage value only needs to be adjusted in combination with the preset magnetization current value, so that precise control of the magnetization process can be achieved on the basis of improving the magnetization efficiency.

[0075] In some of the embodiments, the data processing unit 202 is further used to construct a magnetization channel mapping table. Specifically, the magnetization output of each magnetization channel is controlled to be turned on, the magnetization voltage value corresponding to the magnetization channel is adjusted, and the magnetization current value is detected. When the detected magnetization current value meets the preset magnetization current value, the current magnetization voltage value is determined to be the target magnetization voltage value; until the target magnetization voltage values ​​corresponding to all magnetization channels when the preset magnetization current value is met are obtained, and the magnetization channel mapping table is constructed.

[0076] By testing and recording the corresponding target magnetizing voltage value when the preset magnetizing current value is reached one by one, an accurate mapping relationship is formed. In actual production, the voltage is set quickly and accurately according to this mapping table, which reduces the trial and error process, directly reaches the preset magnetizing state, and improves the accuracy and efficiency of magnetization.

[0077] In some of the embodiments, the data processing unit 202 is further used to: determine the current difference between the current magnetization current value and the preset magnetization current value, and judge whether the current difference is within the preset threshold range; if the current difference is within the preset threshold range, use the current magnetization voltage value in the magnetization operation as the target magnetization voltage value; if the current difference is not within the preset threshold range, determine the target magnetization voltage value according to the magnetization channel mapping table and the preset magnetization current value.

[0078] When the current difference between the detected current magnetizing current value and the preset magnetizing current value is within the preset threshold range, the current magnetizing voltage value may not be adjusted, that is, the current magnetizing voltage value is the target magnetizing voltage value, which avoids unnecessary adjustments and reduces control errors. If the current difference exceeds the preset threshold range, the new target magnetizing voltage value can be determined by combining the magnetizing channel mapping table, ensuring that when the magnetizing current value deviates greatly from the preset current value, it can be corrected in a timely and effective manner, thereby improving the magnetizing control accuracy and the stability of the magnetizing control system.

[0079] The control unit 203 is used to perform a magnetization operation on a target product in a corresponding magnetization channel according to a target magnetization voltage value.

[0080] The target product is magnetized by the target magnetization voltage value corresponding to the preset magnetization current value, thereby ensuring the consistency of the magnetization current of different channels, thereby ensuring the consistency of the magnetization magnetic field and improving the magnetization control effect.

[0081] In some of the embodiments, in the step of performing a magnetization operation on a target product in a corresponding magnetization channel according to a target magnetization voltage value, the control unit 203 is further used to: obtain actual magnetization current values ​​in a plurality of magnetization channels, and determine a current difference between an actual magnetization current value and a preset magnetization current value; if the current difference is not within a preset threshold range, determine a voltage compensation value according to the current difference, and adjust the target magnetization voltage value according to the voltage compensation value.

[0082] By acquiring and comparing the actual magnetizing current value of each magnetizing channel with the preset value in real time, the current inconsistency caused by the difference between channels (such as coil resistance, etc.) can be discovered and corrected in time, thereby ensuring that the magnetizing magnetic field strength of all channels remains highly consistent, and improving the consistency of the magnetic properties of the final product. The process of automatically adjusting the voltage compensation value is based on the actual detected current deviation. This dynamic feedback control strategy significantly enhances the control accuracy of the magnetizing process, allowing the system to quickly respond to external interference and maintain the magnetizing current value within the preset threshold range, reducing the need for human intervention, improving the level of automation, and helping to improve the magnetizing efficiency and magnetizing qualification rate.

[0083] The above settings make the magnetization control system more adaptable to environmental changes (such as temperature fluctuations), material batch differences, etc., and can maintain the stability and consistency of the magnetization process through automatic compensation even under non-ideal conditions, thereby improving the system's stable operation capability and scope of application, and further expanding the applicable scenarios of the magnetization control method.

[0084] In some of the embodiments, the data processing unit 202 is further used to obtain the current magnetic field strength corresponding to the magnetization device; the target magnetization voltage value is adjusted according to the relationship between the current magnetic field strength and the preset magnetic field strength, and the control unit 203 is further used to perform the magnetization operation according to the adjusted target magnetization voltage value.

[0085] Based on the above settings, the embodiment of the present invention also provides another magnetization strategy to ensure the consistency of the multi-channel magnetization magnetic field. That is, the target magnetization voltage value is adjusted in combination with the difference between the current magnetic field strength and the preset magnetic field strength of the magnetization device. This magnetization strategy can be used as a supplement to the target magnetization voltage value determined based on the current magnetization current value, the magnetization channel mapping table, and the preset magnetization current value, that is, the magnetization process is controlled by the dual constraints of the magnetization current value and the magnetization magnetic field, so as to ensure the consistency of the magnetization current and magnetization magnetic field of the multi-channel, and improve the magnetization effect and the magnetization control effect.
