Description

Technical Field

[0001] The present application relates to the field of mechanical control systems, and in particular to a magnetic foreign matter rinsing method, device, medium and program product. Background Art

[0002] During the battery material production process, the incorporation of magnetic foreign matter (such as metal particles like iron, nickel, and cobalt) can cause risks such as internal micro-short circuits and electrolyte contamination, seriously impacting battery safety, cycle life, and energy density. Therefore, accurate detection of magnetic foreign matter in battery materials is a core component of quality control. Rinsing, a key step in the magnetic foreign matter detection process, uses liquid to separate non-magnetic impurities and residual solution attached to the surface of the magnetic foreign matter, ensuring that the collected magnetic foreign matter meets the required purity standards for testing and preventing impurities from interfering with the accuracy of test results.

[0003] Existing rinsing procedures for detecting magnetic foreign matter in battery materials rely primarily on manual labor. Operators manually pour a suspension containing magnetic foreign matter into a beaker, repeatedly attract the foreign matter with a handheld magnet, and simultaneously empty the waste liquid and rinse the beaker's interior. Throughout this process, key parameters such as liquid filling volume, magnet attraction time, and number of rinses rely on manual judgment, resulting in a lack of standardized operating procedures.

[0004] However, this manual rinsing method has significant technical bottlenecks. The manual rinsing step consumes a lot of time and manpower, has poor consistency, and has high labor costs. There is an urgent need for an automated rinsing method for magnetic foreign matter. Summary of the Invention

[0005] The present application provides a magnetic foreign matter rinsing method, device, medium and program product for solving the problem that the existing magnetic foreign matter rinsing process consumes a lot of time and manpower, resulting in low magnetic foreign matter rinsing efficiency.

[0006] In the first aspect, the present application provides a magnetic foreign matter rinsing method, which is applied to a magnetic foreign matter rinsing device, and the method includes: obtaining weight data of the beaker placement area through a weight sensor to determine the placement status of the beaker and the liquid containing magnetic foreign matter; after confirming that the beaker and the liquid containing magnetic foreign matter are successfully placed, obtaining a visual parameter control setting, and the visual parameter control setting includes at least the total number of cycles, the magnetic steel motion state parameters and the beaker rinsing intensity; after obtaining the suction instruction, controlling the clamp to clamp the beaker; after obtaining the instruction to start cleaning, rinsing the liquid containing magnetic foreign matter according to the set total number of cycles.

[0007] By adopting the above technical solution, the placement status of the beaker and the liquid containing magnetic foreign matter is first determined by using a weight sensor, which can avoid rinsing failures caused by abnormal placement and ensure the smooth progress of subsequent operations. Then, the visual parameter control settings are obtained, allowing users to flexibly set the rinsing conditions according to actual needs. Controlling the clamp to clamp the beaker can ensure the stability of the beaker during the rinsing process. Rinsing according to the set total number of cycles realizes the automation of the rinsing process, reduces manual intervention, avoids the instability and high repeatability of manual operation, thereby saving a lot of time and manpower and improving rinsing efficiency.

[0008] In combination with some embodiments of the first aspect, in some embodiments, after obtaining the instruction to start cleaning, the step of rinsing the liquid containing magnetic foreign matter according to the total number of cycles specifically includes: controlling the biaxial small magnet below the beaker to perform eccentric movement according to the set magnet motion state parameters to adsorb the magnetic foreign matter; controlling the beaker to dump according to the set angle parameters and the set dumping speed parameters; controlling the first water outlet to flush the inner wall of the beaker according to the set time and the set flushing intensity; controlling the beaker to return to the center; controlling the biaxial small magnet to perform a de-position operation to separate the magnetic foreign matter; controlling the second water outlet located above the beaker to add water to the beaker according to the set water addition amount; and repeating the above steps according to the set total number of cycles.

[0009] By adopting the above technical solution, the eccentric motion of the small dual-axis magnet is controlled to absorb magnetic foreign matter, effectively separating it from the liquid. Controlling the beaker's tipping and rinsing removes the adsorbed magnetic foreign matter from the beaker's inner wall. Controlling the beaker's return to center, the de-positioning of the small dual-axis magnet, and the addition of water completes a single rinse cycle. By cycling these steps for a set total number of cycles, a complete automated rinsing process is formed, reducing the number of manual steps and time, avoiding potential errors during manual rinsing, and improving rinsing accuracy and efficiency, thereby saving significant time and manpower.

[0010] In combination with some embodiments of the first aspect, in some embodiments, after the step of controlling the biaxial small magnet under the beaker to perform eccentric movement according to the set magnet motion state parameters to adsorb magnetic foreign matter, it also includes: using a magnetic foreign matter concentration sensor to obtain the magnetic foreign matter distribution data in the beaker in real time; determining the area with the highest magnetic foreign matter concentration in combination with the magnetic foreign matter distribution data, and increasing the eccentric movement amplitude and magnetic field strength of the biaxial small magnet in this area.

[0011] By adopting this technical solution, after the dual-axis small magnet absorbs magnetic foreign matter, the magnetic foreign matter concentration sensor is used to obtain distribution data, providing a precise understanding of the distribution of magnetic foreign matter. Integrating this distribution data, the eccentric motion amplitude and magnetic field strength of the dual-axis small magnet in the area with the highest magnetic foreign matter concentration are increased, enabling more targeted absorption of magnetic foreign matter and improving absorption efficiency. This reduces unnecessary absorption operations, shortens absorption time, and avoids the tedious process of repeatedly manually adjusting the position and strength of the magnet, thereby saving time and manpower and making the rinsing process more efficient.

[0012] In combination with some embodiments of the first aspect, in some embodiments, in the above steps of repeating the above steps according to the set total number of cycles, it also includes: obtaining the current magnetic intensity of the magnetic foreign matter in the beaker in real time; calculating the loss value of the magnetic foreign matter based on the initial magnetic intensity and the current magnetic intensity, and the initial magnetic intensity is the magnetic intensity obtained by detecting the liquid containing magnetic foreign matter through the magnetic field sensor before starting cleaning; if the loss value exceeds the preset loss threshold, a reminder is issued to the visual end, and the remaining number of cycles is changed to 0.

[0013] By adopting this technical solution, the current magnetic intensity of the magnetic foreign matter in the beaker is acquired in real time during the rinsing process, and the loss value is calculated based on the initial magnetic intensity. If the loss value exceeds a preset threshold, an alert is sent to the visual terminal and the remaining cycles are stopped. This can promptly detect abnormal loss of magnetic foreign matter and prevent ineffective rinsing operations from continuing. This reduces unnecessary rinsing steps, saving time and resources, while also avoiding the trouble of manually monitoring the loss of magnetic foreign matter, reducing labor costs and improving rinsing efficiency and quality.

[0014] In combination with some embodiments of the first aspect, in some embodiments, the step of obtaining weight data of the beaker placement location through a weight sensor to determine the placement status of the beaker and the liquid containing magnetic foreign matter specifically includes: after detecting that the weight data has changed and the weight data stops changing within a set time, obtaining the current placement weight data; and comparing the placement weight data with the preset beaker weight data to determine the placement status of the beaker and the liquid containing magnetic foreign matter.

[0015] By employing this technical solution, the placement weight data is captured after a weight change is detected and the change ceases, accurately capturing the placement status of the beaker and the liquid containing the magnetic foreign matter. The placement weight data is then compared with the preset beaker weight data to determine the placement status. This method avoids the uncertainty and tediousness of manual determination of placement status, enabling quick and accurate determination of placement status, providing a reliable basis for subsequent rinsing operations, reducing the time and effort required for manual verification, and improving overall operational efficiency.

[0016] In combination with some embodiments of the first aspect, in some embodiments, the step of comparing the placement weight data with the preset beaker weight data to determine the placement status of the beaker and the liquid containing magnetic foreign matter specifically includes: if the difference between the placement weight data and the beaker weight data is within the set threshold, it is determined that the current placed object is a beaker, and a reminder to add the liquid containing magnetic foreign matter is sent to the user through the visual parameter control interface; if the placement weight data is greater than the beaker weight data, and the difference exceeds the set threshold, it is determined that the current placed object is a beaker containing the liquid containing magnetic foreign matter, and in combination with the preset preference setting parameters, the user's preference parameter selection for the magnetic foreign matter rinsing selection is displayed through the visual parameter control interface.

[0017] By employing this technical solution, the difference between the weight of the placed object and the weight of the beaker is used to determine the object's condition. If the difference is within a set threshold, it is identified as a beaker and a reminder to add liquid is displayed. If the difference exceeds the threshold, it is identified as a beaker containing liquid and a display of preferred parameters is displayed. This intelligent judgment method guides users to correct operation, avoiding the difficulties and errors of manual object identification. Users can select preferred parameters based on the displayed parameters, making the rinsing process more tailored to their actual needs, reducing the time and effort of manual parameter adjustment, improving operational convenience and efficiency, and saving significant time and manpower.

[0018] In combination with some embodiments of the first aspect, in some embodiments, if the difference between the placed weight data and the beaker weight data is within a set threshold, it is determined that the currently placed object is a beaker, and after the step of sending a reminder to the user to add the magnetic foreign matter-containing liquid through a visual parameter control interface, it also includes: when it is detected that the weight data begins to change, it is determined that the magnetic foreign matter-containing liquid is being injected at the current time point; if the weight data no longer changes within the set time, it is determined that the magnetic foreign matter-containing liquid has been injected; the user's preference setting parameters are obtained, and in combination with the preference setting parameters, the preference parameter selection for rinsing magnetic foreign matter is displayed through the visual parameter control interface.

[0019] By adopting this technical solution, the liquid injection process is automatically monitored and parameter setting is guided, eliminating the need for manual monitoring of liquid injection and parameter setting. This allows users to complete rinsing operations more conveniently, saving time and manpower, and improving the automation and efficiency of the rinsing process.

[0020] In the second aspect, the present application provides a magnetic foreign matter rinsing device, which includes: one or more processors and a memory; the memory is coupled to the one or more processors, and the memory is used to store computer program code, and the computer program code includes computer instructions, and the one or more processors call the computer instructions to enable the magnetic foreign matter rinsing device to perform the method described in the first aspect and any possible implementation method of the first aspect.

[0021] In a third aspect, the present application provides a computer-readable storage medium comprising instructions, which, when executed on a magnetic foreign matter rinsing device, causes the magnetic foreign matter rinsing device to execute the method described in the first aspect and any possible implementation of the first aspect.

[0022] In a fourth aspect, the present application provides a computer program product, which, when run on a magnetic foreign matter rinsing device, enables the magnetic foreign matter rinsing device to perform the method described in the first aspect and any possible implementation of the first aspect.

[0024] 1. The system uses a weight sensor to determine the placement status, obtains visual parameter control settings, controls the fixture to clamp the cup, and rinses according to the set number of cycles.

It should also be understood that the term "and / or" used in the present application refers to and encompasses any or all possible combinations of one or more of the listed items.

[0035] In the following, the terms "first" and "second" are used for descriptive purposes only and should not be understood to imply or suggest relative importance or implicitly indicate the number of the technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of this application, unless otherwise specified, "plurality" means two or more.

[0036] For ease of understanding, the structure of the magnetic foreign matter rinsing device provided in this embodiment is described below. Figure 1 , which is a structural diagram of the magnetic foreign matter rinsing device in an embodiment of the present application.

[0037] Figure 1The MAE1000 magnetic foreign body rinsing device, measuring 75cm x 75cm x 87cm, features a beaker placement area at the top. A built-in weight sensor detects the weight of the beaker and liquid, determining its placement status (empty / filled). A small biaxial magnet is mounted at the bottom, absorbing magnetic foreign matter through eccentric motion. A motor-driven clamp is located on one side of the beaker placement area, gripping and releasing the beaker upon command, ensuring stability during the rinsing process. The first water outlet, located on the lower side of the beaker when tilted, rinses the inner wall. The second outlet, located directly above the beaker, is used to meter in rinse water.

[0038] The following describes the process of the method provided by this embodiment in combination with the above device structure. Figure 2 , is a flow chart of the magnetic foreign matter rinsing method in an embodiment of the present application.

[0039] S201, obtaining weight data of the beaker placement area through a weight sensor to determine the placement status of the beaker and the liquid containing the magnetic foreign matter;

[0040] The magnetic foreign matter rinsing device is equipped with a weight sensor to detect the combined weight of the beaker and the liquid containing the magnetic foreign matter, both placed in a designated location. The weight sensor can be a strain gauge pressure sensor, which converts the pressure change generated when the beaker is placed on top of the sensor into an electrical signal for output. Alternatively, a capacitive pressure sensor can be used, detecting changes in the distance between two electrode plates and, in turn, weight changes. Alternatively, a more accurate floating-point sensor can be used, utilizing the displacement of a floating plate to detect weight. This is not a limitation here.

[0041] Specifically, if a strain gauge pressure sensor is used, then when the magnetic foreign matter rinsing device detects a significant change in the voltage signal output by the weight sensor, which then stabilizes after a period of time, it indicates that the weight value of the placement area has changed and stabilized. At this time, the device will obtain the current voltage output by the weight sensor, perform analog-to-digital conversion, and calculate the current placement weight data. For example, if the stabilization time is set to 5 seconds, if the monitored weight signal fluctuates below a certain set value within 5 seconds, the weight value at that time will be recorded as the placement weight data.

[0042] The magnetic foreign body rinsing device stores preset weight parameters for beakers of different sizes. Upon receiving the placed weight data, the device automatically matches the weight data for the beaker of the current size. If a match is successful, the device reads the corresponding preset beaker weight and compares it with the currently acquired placed weight data. If the difference between the placed weight data and the beaker weight data is within a set threshold, the device determines that the currently placed object is an empty beaker, and a reminder to add the magnetic foreign body liquid is sent to the user through a visual parameter control interface. For example, if the weight error threshold is set to ±10 grams and the absolute difference between the current placed weight data and the matched beaker weight data is within 10 grams, the device determines that the currently placed object is an empty beaker. The magnetic foreign body rinsing device then displays a prompt on the display interface, "Please place the magnetic foreign body liquid," and plays a voice reminder to inform the operator that liquid needs to be added. After the reminder to add liquid, if the magnetic foreign body rinsing device detects another change in the weight data, it determines that the user is adding the magnetic foreign body liquid to the beaker and records the time at which the addition of the magnetic foreign body liquid is completed. In order to filter out signal noise, the weight change can be set to continue for more than 1 second to confirm the start of liquid injection. If the monitored weight data is basically stable within a period of time (for example, 10 seconds) and the fluctuation range is less than a certain threshold, it can be confirmed that the injection process of the liquid containing magnetic foreign matter is complete. At this time, the last stable weight value will be saved to provide data for the subsequent calculation of the liquid volume. After the liquid injection is completed, the magnetic foreign matter rinsing device will retrieve the user's preset rinsing parameter preferences from the database and display it on the interface, prompting the user to confirm the selected preference parameter combination for subsequent rinsing operations. The user can also adjust the parameters according to actual conditions on this basis.

[0043] On the contrary, if the absolute value of the difference between the placed weight data and the weight data of the matching beaker exceeds a preset threshold, such as 10 grams, it can be determined that the placed beaker is already filled with liquid, and the user's preferred parameter combination needs to be read next.

[0044] In summary, this step describes in detail how the magnetic foreign matter rinsing device uses a weight sensor to intelligently determine the placement status, which not only avoids the error of manual confirmation, but also realizes the automatic detection of the liquid injection amount, provides accurate data for subsequent operations, reduces manual participation, simplifies the operation process, and improves the degree of automation.

[0045] S202: After confirming that the beaker and the liquid containing the magnetic foreign matter are successfully placed, obtaining a visualization parameter control setting, wherein the visualization parameter control setting includes at least a total number of cycles, a magnetic steel motion state parameter, and a beaker flushing intensity;

[0046] In step S201, after the magnetic foreign matter rinsing device has used the weight sensor to determine that the beaker and the liquid containing magnetic foreign matter have been successfully placed in the designated position, the device will enter the parameter setting process.

[0047] First, the magnetic foreign body rinser prompts the user to set parameters on the touchscreen interface. Visual parameters such as the total number of cycles, magnetic steel motion parameters, and beaker rinsing intensity are displayed. Users can select and determine specific values for each parameter by touching a slider, clicking a button, or rotating a knob.

[0048] For example, the total number of cycles can be set between 3 and 10 times; magnetic motion parameters include magnetic trajectory (circular or linear), frequency (rpm), and amplitude (eccentric distance); and beaker rinse intensity parameters include outlet water pressure, spray duration, and spray angle. The interface also displays recommended default values for each parameter, allowing users to choose whether to use the default values or adjust them based on the type and content of the magnetic foreign matter and desired cleaning effect.

[0049] In addition, the magnetic foreign body rinsing device also provides multiple preset rinsing modes, corresponding to different application scenarios, and each mode includes an optimized parameter combination. For example, "Standard Mode" corresponds to the default parameters for general scenarios; "Gentle Mode" uses a lower water spray intensity and is suitable for situations where the magnetic foreign body particles are small to avoid dispersion; "Strong Mode" can be used for liquids with a large number of foreign bodies or serious contamination. Users can select the appropriate preset mode based on their actual situation. The system will call the visual parameter values contained in the mode and allow users to fine-tune them based on this.

[0050] Figure 3 In the (a) interface, the current magnetic block status, beaker status, fixture status and set flushing intensity are displayed. On the right side of the interface are the initial position option, parameter configuration option, suction / release option and start cleaning option. If the user clicks the parameter configuration option, the following will appear: Figure 3 The interface shown in (b) in the figure displays the specific contents of the visual parameter control settings for the current rinsing action, including but not limited to the amount of water added per time, the number of magnetic block rotations, the number of clockwise times, the number of counterclockwise times, the flushing time and the total number of cycles. After the user has confirmed that the above parameters are correct, he can click "Return Control" in the lower right corner of the interface to start the cleaning operation.

[0051] S203, after receiving the suction instruction, controlling the clamp to clamp the beaker;

[0052] exist Figure 3In the (a) interface, if you click the "Attract / Release" option, the magnetic foreign matter rinsing device will receive the corresponding attraction instruction for the beaker. If you click the option again, you will receive the release instruction for the beaker. After the magnetic foreign matter rinsing device determines that the current operation is attraction, it controls the clamp to gradually clamp. After confirming that the beaker is clamped, the control unit of the magnetic foreign matter rinsing device will continue to monitor the attraction force of the clamp to prevent the clamp from loosening. If the force is detected to be lower than the set value, the motor will restart to supplement the attraction force. The built-in motor drives the clamp to accurately attract the beaker, which not only realizes automated operation and avoids uncontrollable errors in manual attraction, but also ensures that the beaker is in a stable clamped state during the entire rinsing process, laying the foundation for subsequent actions such as pouring the beaker and rinsing the inner wall.

[0053] S204: After obtaining the instruction to start cleaning, the liquid containing magnetic foreign matter is rinsed according to the set total number of cycles.

[0054] After the user confirms that the beaker is sucked in, he can click Figure 3 Click the "Start Cleaning" option in the (a) interface, the device starts the cleaning process, and the visual interface will display the following Figure 3 The interface shown in (c) above contains the following information: "Cleaning...", "Current step: rinsing", "1 / 3 cycle", "estimated to take * minutes", etc.

[0055] The specific rinsing process is as follows: The control unit of the magnetic foreign matter rinsing device will accurately control the eccentric movement of the biaxial small magnet at the bottom of the beaker placement module according to the magnet motion state parameter value pre-set by the user in the parameter setting interface to absorb the magnetic foreign matter in the beaker. Specifically, the magnet motion state parameters include motion trajectory, motion frequency, motion amplitude, etc. The motion trajectory can be set to circular or linear, the motion frequency is the rotation speed per minute, and the motion amplitude refers to the eccentric distance of the magnet. The magnetic foreign matter rinsing device uses a two-axis independently controlled stepper motor to achieve complex motion trajectory and precise positioning of the magnet. During the eccentric motion, the magnetic foreign matter will move toward the magnet and adhere under the action of the magnetic field generated by the magnet. By appropriately setting the eccentric amplitude and frequency, it can be ensured that the magnetic foreign matter in the beaker is adsorbed as efficiently as possible to the area inside the beaker corresponding to the magnet.

[0056] After the magnetic steel adsorption is completed, the control unit of the magnetic foreign matter rinsing device will drive the clamp to drive the beaker to perform a dumping operation to pour out the excess liquid corresponding to the magnetic foreign matter from the beaker. Specifically, the beaker dumping control parameters include the dumping angle and the dumping speed. The dumping angle can be set within a suitable range, such as 160-170 degrees; the dumping speed can be set to a uniform dumping speed of 10-30 degrees per second. The control unit will accurately control the beaker placement module that carries the beaker to tilt the beaker smoothly to the dumping state defined by the parameters according to the set dumping speed and angle to pour out the excess liquid in the beaker. During the dumping process, controlling the uniform and slow dumping can avoid violent shaking of the beaker, thereby reducing the probability of magnetic foreign matter adsorbed on the internal area of the beaker corresponding to the magnetic steel falling off into the liquid again.

[0057] After the beaker is tilted, the control unit of the magnetic foreign matter rinsing device will accurately control the first water outlet to spray water to rinse the inner wall of the beaker. The first water outlet is set in the corresponding area when the beaker is tilted, so that when the beaker is tilted to pour out excess water, the first water outlet can be controlled to rinse the bottom area of the inner wall of the beaker according to the rinsing parameters. In this way, a small amount of impurities on the inner wall of the bottom of the beaker can be cleaned. The rinsing parameters include pre-set rinsing time and rinsing intensity.

[0058] After rinsing, the magnetic foreign body rinsing device's control unit controls the motor-driven fixture to smoothly return the tilted beaker to its original vertical position, preparing for the subsequent off-site water addition operation. Once the beaker is upright, the control unit instructs the dual-axis small magnet to perform an off-site operation, such as deactivating its magnetic field using a pre-set method. This is intended to dislodge any magnetic foreign matter adsorbed on the magnet's corresponding internal area of the beaker.

[0059] After the biaxial small magnet is disengaged and releases the magnetic foreign matter, the control unit of the magnetic foreign matter rinsing device will control the second water outlet to add water to the beaker according to the preset water addition amount. The second water outlet is set directly above the beaker, and the amount of water added can be predetermined based on the volume of the beaker and the volume of the discharged liquid. The control unit will accurately control the opening time of the solenoid valve of the second water outlet and the output water volume of the water pump according to the set water addition value to achieve the set volume of water addition. To monitor the accuracy of water addition, a liquid level sensor can be configured to detect the liquid level in the beaker in real time, so that the control unit can adjust the amount of water added according to the liquid level feedback to ensure that the water addition is accurate to the milliliter level. After the water addition is completed, the next rinsing cycle will be carried out.

[0060] After completing a rinse cycle, the control unit reads the total number of cycles set by the user on the interface (for example, if it is set to 5). The control unit then automatically controls the entire process, from attracting magnetic foreign objects to adding water, for a complete cycle of 5 times. After each cycle, the control unit determines whether the current cumulative number of cycles has reached the set total. If not, the control unit continues to execute a new cycle until the cumulative number of cycles reaches the set total, and the rinse process ends.

[0061] The embodiments of this application effectively address the low rinsing efficiency problem of existing technologies, which relies heavily on manual operations. They achieve intelligent judgment of placement status, flexible parameter setting, automatic beaker clamping, and automated completion of the rinsing cycle. This significantly reduces manual operations and labor costs, improves the automation and efficiency of rinsing, and makes rinsing parameter control more precise and reliable, thereby saving time and resources.

[0062] In some embodiments, during the magnetic foreign matter rinsing process, the magnetic foreign matter in the beaker may be unevenly distributed due to uneven liquid flow, precipitation or stirring. If only a fixed-parameter magnetic steel motion mode is used, the magnetic foreign matter in some areas may not be fully adsorbed, affecting the rinsing efficiency. To this end, the magnetic foreign matter rinsing device adopts a dynamic adjustment strategy to optimize the motion parameters of the dual-axis small magnet in real time to ensure efficient adsorption. The magnetic foreign matter rinsing device is equipped with a built-in magnetic foreign matter concentration sensor such as a magnetoresistive sensor, which scans the magnetic field intensity distribution in different areas of the beaker at a high frequency. The sensor is usually installed in the device area corresponding to the bottom and side walls of the beaker to form a multi-point detection network to ensure coverage of the entire liquid area. The sensor array that detects the magnetic field can detect the magnetic field intensity at each position in real time, generate a magnetic field distribution map, and then normalize it to eliminate noise interference.

[0063] Based on the correspondence between magnetic field strength and magnetic foreign matter concentration, the foreign matter concentration value in each area is calculated, and high-concentration areas are marked. Assuming a beaker is divided into three detection areas: left, center, and right. The sensor measures magnetic field strengths as follows: left: 120 mT (high concentration); center: 60 mT (medium concentration); right: 30 mT (low concentration). The device's control unit determines that the left area is a high-concentration area for magnetic foreign matter and prioritizes increased adsorption. Based on the sensor data, the device automatically adjusts the eccentric motion amplitude and magnetic field strength of the biaxial small magnet to optimize adsorption efficiency. Specifically, if the concentration in a certain area is high, the magnet's motion radius in that area is increased or its dwell time is prolonged to improve adsorption probability. More specifically, a pre-set motor can be used to control the magnet's eccentricity, resulting in a denser motion trajectory in the target area. In high-concentration areas, the control unit increases the magnet's drive current, increasing the magnetic field strength to enhance adsorption. In traditional rinsing methods, the magnet may repeatedly pass through low-concentration areas, resulting in wasted time. The embodiments of this application utilize real-time path planning to prioritize high-concentration areas and reduce wasted motion.

[0064] In some embodiments, during the process of tilting the beaker to rinse, a small amount of magnetic attraction of foreign objects may be lost due to reasons such as the tilting angle exceeding the degree of inclination that the adhesion of the foreign objects can withstand, or the water flow being too strong during rinsing directly washing away the foreign objects. In this case, a loss reminder can be issued to avoid losing more magnetic foreign objects. The following is a more detailed description of the process of the method provided in this embodiment. Please refer to Figure 4 , is another flow chart of the magnetic foreign matter rinsing method in an embodiment of the present application.

[0065] S401, obtaining the current magnetic intensity of the magnetic foreign matter in the beaker in real time;

[0066] During the magnetic foreign body rinsing process, real-time monitoring of the magnetic strength of the foreign matter in the beaker is a critical step in ensuring effective rinsing and minimizing waste. The magnetic foreign body rinsing device uses a built-in magnetic field sensor to detect the magnetic field strength of the foreign matter in the beaker in real time. The sensor is typically installed on the bottom or side of the beaker, covering the main area of the beaker and ensuring comprehensive and accurate detection data.

[0067] In practice, the magnetic field sensor collects magnetic field data at a fixed frequency (e.g., 10 times per second) and transmits the data to the control unit for processing. The control unit filters and calibrates the raw data to eliminate ambient magnetic field interference and sensor noise. The calibrated data is converted into magnetic intensity values and recorded as the current magnetic intensity.

[0068] S402, calculating the loss value of magnetic foreign matter by combining the initial magnetic intensity and the current magnetic intensity, wherein the initial magnetic intensity is the magnetic intensity obtained by detecting the liquid containing magnetic foreign matter by the magnetic field sensor before starting cleaning;

[0069] The initial magnetic intensity refers to the baseline magnetic intensity value obtained by detecting the liquid containing magnetic foreign matter through the magnetic field sensor before the rinsing process begins. This step is usually completed after the beaker and liquid are successfully placed and before the rinse cycle begins. The control unit will record the magnetic field intensity at this time as the initial value for subsequent calculation of the loss value. During the rinsing process, the control unit will calculate the difference between the current magnetic intensity and the initial magnetic intensity in real time and convert it into a loss value. The loss value can be calculated using the following formula:

[0070] Loss value = (initial magnetic strength - current magnetic strength) / initial magnetic strength × 100%. For example, if the initial magnetic strength is 80mT and the current magnetic strength is 60mT, the loss value is 25%. The device also dynamically adjusts the loss value based on the progress of the rinse cycle (such as the current cycle number). For example, the loss value is usually small after the first cycle, but may gradually increase with subsequent cycles.

[0071] S403: If the loss value exceeds the preset loss threshold, a reminder is sent to the visual terminal, and the remaining number of cycles is changed to 0.

[0072] The preset loss threshold is a safety boundary set based on experimental data or experience, used to determine whether the loss of magnetic foreign matter is within an acceptable range. For example, if the threshold is set to 20%, when the loss value exceeds 20%, the device will determine that the loss of magnetic foreign matter during the rinse process is excessive and requires immediate intervention.

[0073] When the control unit detects that the loss value exceeds the threshold, it triggers the following actions: 1. Issues a reminder to the visual terminal: A warning message (such as "Magnetic foreign matter loss exceeds the limit!") is displayed on the touch screen interface, and the user is prompted by sound or light. The warning message may include the specific loss value and recommended actions (such as checking the beaker or adjusting parameters). 2. Stops subsequent cycles: The remaining number of cycles is forcibly set to 0, terminating the rinsing process to prevent further loss. At this point, the device automatically enters standby mode, waiting for user intervention.

[0074] Through real-time monitoring and loss value calculation, this method can promptly detect abnormalities during the rinsing process, avoiding ineffective operations and wasted resources. Furthermore, automated reminder and termination functions reduce the burden of manual monitoring, significantly improving the safety and efficiency of the rinsing process.
