[0002] In the operation of traditional magnetizers, operators face a significant challenge, which is the difficulty in real-time and accurate grasp of the stacking progress of the products to be magnetized. This problem stems from the following factors: First, the magnetization process usually involves a large number of products to be magnetized, which need to be stacked in a specific order and manner. Due to the large number of products, it is difficult for operators to accurately count and track the position of each product in a short period of time. Secondly, the structure of the magnetizer is often more complex, and some stacking areas may not be easy for operators to directly observe. This limited line of sight makes it difficult for operators to fully grasp the actual situation of stacking.

[0048] The realization of the purpose, functional features and advantages of the present invention will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0049] It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.

[0050] Reference Figures 1 to 3 , the present invention proposes a control system for a fully automatic gasket adding magnetizing machine, the system comprising: a pressure acquisition module 10, a controller 20, and a status display module 30;

[0051] Among them, the control system of the fully automatic shim-adding magnetizing machine is to stack the products or shims to be magnetized on the magnetizing coil lifting mechanism platform in turn by a suction nozzle grabbing mechanism. The lifting mechanism platform in the coil drops one grid each time a product or shim to be magnetized is placed. When the products to be magnetized are stacked to a maximum preset stacking number, magnetization begins. The pressure acquisition module 10 is connected to the lifting mechanism platform in the coil through a spring. The pressure acquisition module 10 is also connected to the controller 20, and the controller 20 is connected to the status display module 30;

[0052] The pressure acquisition module 10 is used to collect the pressure transmitted by the lifting mechanism platform in the coil through the spring, and convert the pressure into a corresponding pressure electric signal and transmit it to the controller 20;

[0053] The controller 20 is used to output a corresponding status display signal to the status display module 30 according to the size of the pressure electric signal;

[0054] The status display module 30 is used to display the number of stacked products to be magnetized based on the status display signal when receiving the status display signal.

[0055] It should be noted that the pressure acquisition module 10 senses weight changes through a spring connected to the lifting mechanism platform. Whenever a new product or gasket to be magnetized is placed on the platform, the total weight increases, causing the spring to compress and produce a measurable pressure change. The module converts the sensed mechanical pressure into an electrical signal. This is usually achieved through a pressure sensor (such as a strain gauge, piezoelectric element, etc.). The module may include a signal conditioning circuit for amplifying, filtering and processing the original signal to improve signal quality and reliability. The processed signal is converted into a standardized electrical signal (such as a 4-20mA current signal or a 0-5V voltage signal) and then transmitted to the controller 20. For example, assume that a product to be magnetized weighs 50 grams and the gasket weighs 5 grams. The platform is unloaded and the pressure acquisition module 10 outputs a reference signal (such as 4mA). The first product is placed: the weight increases by 50 grams, and the pressure acquisition module 10 may output 4.5mA. Place the gasket: the weight increases by 5 grams, and the output of the pressure acquisition module 10 may become 4.55mA. Continuous stacking: As products and gaskets are continuously stacked, the output signal will gradually increase. For example, after 10 products and 9 gaskets, the total weight is 545 grams, and the output may reach 9.5mA. Reaching the preset number: Assuming that 20 products are preset to be stacked, when the weight reaches about 1045 grams, the output may be 15mA, at which point the system recognizes that the preset number has been reached. Abnormal detection: If the weight suddenly increases significantly after a certain placement (such as an increase of 100 grams), it may indicate a stacking error, and the system can alarm accordingly. In this way, the pressure acquisition module 10 can reflect the stacking progress in real time and accurately, and provide the necessary data support for the controller 20, thereby realizing the automatic control and status display of the entire system. This greatly improves the accuracy and efficiency of the operation and reduces the possibility of human error.

[0056] The controller 20 plays a core role in the control system of the fully automatic gasket magnetizing machine and is the "brain" of the entire system. Its specific functions and uses include: Data reception and processing: receiving pressure electrical signals from the pressure acquisition module 10. Digital processing and analysis of the received signals. Stacking progress calculation: converting the pressure signal into the stacking quantity according to the preset product and gasket weight parameters. Real-time calculation of the current stacking progress. Status judgment: comparing the current stacking quantity with the preset maximum stacking quantity. Determine whether the conditions for starting magnetization are met. Control signal output: sending stacking progress information to the status display module 30. When the preset stacking quantity is reached, sending an instruction to start magnetization. Abnormal detection and processing: monitoring whether the pressure change is in line with expectations and detecting possible stacking errors. When an abnormality is detected, an alarm or a command to stop the operation is issued. System coordination: coordinating the work of various parts such as the nozzle grabbing mechanism and the lifting mechanism platform. Ensure the orderly progress of the entire stacking and magnetization process. Parameter setting and adjustment: allowing operators to enter or modify parameters such as product weight and maximum stacking quantity. Automatically adjust relevant parameters according to different product models. Data recording and statistics: record the number of stacks, time and other information for each operation. Perform production statistics, such as daily output, efficiency, etc. Human-computer interaction interface: provide an operation interface that allows operators to view system status, modify settings, etc. Display current operation status, warning information, etc. System diagnosis: perform self-diagnosis to detect whether each part of the system is working properly. Provide diagnostic information when a system failure is found. Communication function: exchange data with other systems or equipment. Can support remote monitoring and control functions. Safety control: implement safety protection measures such as overload protection, emergency stop, etc. Ensure the safety of operators and equipment. Through these functions, the controller 20 realizes the automatic control of the entire magnetization process, greatly improving production efficiency and accuracy, while reducing the possibility of human error. It not only simplifies the operation process, but also provides more data analysis and optimization possibilities, providing a solid foundation for improving overall production quality and efficiency.

[0057] The status display module 30 plays an important role in information output in the control system of the fully automatic shim-adding magnetizing machine, and is mainly used to provide intuitive and real-time system operation status information to operators or supervisors. Specifically, the functions and uses of the status display module 30 include: stacking progress display: real-time display of the number of products and shims currently stacked. It can be displayed in the form of numbers, progress bars or percentages. Magnetization status indication: Displays whether it is currently in the magnetization state. Indicators of different colors can be used to indicate (such as green for magnetization and red for standby). Abnormal warning: When an abnormal situation is detected (such as stacking error, abnormal pressure), a warning message is displayed. It can be combined with an audible and visual alarm system to attract the operator's timely attention. Operation guide: Displays prompt information for the next operation, such as "Please start stacking", "Prepare for magnetization", etc. Parameter display: Displays the currently set parameters, such as the preset maximum stacking quantity, the weight of a single product, etc.

[0058] Further, the outputting of a corresponding status display signal to the status display module 30 according to the size of the pressure electrical signal includes:

[0059] Determine the pressure electrical signal value when the lifting mechanism platform is empty, the pressure electrical signal value when the lifting mechanism platform is fully loaded, the preset maximum stacking quantity, and the pressure electrical signal value from the pressure acquisition module 10;

[0060] The number of products to be magnetized currently stacked is determined by a linear mapping formula based on the pressure electrical signal value when the lifting mechanism platform is empty, the pressure electrical signal value when the lifting mechanism platform is fully loaded, the preset maximum stacking quantity, and the pressure electrical signal value from the pressure acquisition module 10;

[0061] Convert the number of products to be magnetized into corresponding status display signals to the status display module 30;

[0062] Wherein, the linear mapping formula is:

[0063]

[0064] Where P min is the pressure electrical signal value when the lifting mechanism platform is unloaded, P max is the pressure electrical signal value when the lifting mechanism platform is fully loaded, N max is the preset maximum stacking quantity, N is the number of products to be magnetized that are currently stacked, and P is the pressure electrical signal value from the pressure acquisition module 10.

[0065] It should be noted that the number of products to be magnetized that are currently stacked is the output result of the formula, indicating how many products to be magnetized have been stacked. It is an integer, indicating the actual number of products. The preset maximum stacking number is the maximum number of stackable products preset by the system. It represents the number of products in the fully loaded state. The pressure electrical signal value from the pressure acquisition module 10 is the current actual measured pressure value, provided by the pressure acquisition module 10. It increases with the increase in the number of stacked products. The pressure electrical signal value when the lifting mechanism platform is unloaded is the reference pressure value when no products are placed on the platform. It represents the initial state or zero point of the system. The pressure electrical signal value when the lifting mechanism platform is fully loaded is the pressure value when the platform is filled with the preset maximum number of products. It represents the fully loaded state of the system. This formula assumes that there is a linear relationship between pressure and the number of products, that is, the pressure will increase evenly with each additional product. It estimates the current number of products by linearly interpolating the current pressure value between the minimum value (unloaded) and the maximum value (full load). The advantages of using this method are: simple and intuitive, easy to implement. It can adapt to products of different weights by simply adjusting the pressure electrical signal value when the lifting mechanism platform is fully loaded and the preset maximum stacking number. It can automatically compensate for some system errors, such as the platform's own weight. It should be noted that this formula assumes that all products have the same weight and that pressure and weight are strictly linearly related. In actual applications, nonlinear factors can be considered or more complex calibrations can be performed to improve accuracy.

[0066] Furthermore, the control system of the fully automatic shim adding magnetizing machine further comprises: a wireless communication module 40;

[0067] The wireless communication module 40 is connected to the controller 20 and the terminal device respectively;

[0068] The controller 20 is further used to output a corresponding status display signal to the wireless communication module 40 according to the size of the pressure electrical signal;

[0069] The wireless communication module 40 is used to send the status display signal to the terminal device by wireless transmission when receiving the status display signal, so that the terminal device can display the status of the stacked number of the products to be magnetized based on the status display signal.

[0070] It should be noted that the wireless communication module 40: This is a new component of the system. It is connected to both the controller 20 and the terminal device. The main function is to realize wireless data transmission between the system and the remote terminal device. Extended function of the controller 20: In addition to outputting signals to the status display module 30, the controller 20 now also outputs status display signals to the wireless communication module 40. This means that the data processed by the controller 20 can now be transmitted to the outside of the system. Function of the wireless communication module 40: Receive status display signals from the controller 20. Transmit these signals to the terminal device wirelessly. Terminal device: This can be a mobile phone, tablet computer or other portable device. Receive status display signals from the wireless communication module 40. Display the number of stacked products to be magnetized based on the received signal. The significance and advantages of this function: Remote monitoring: Operators or managers can monitor the production status without direct contact with the machine. Improve the flexibility and convenience of monitoring. Real-time data acquisition: The latest production data can be obtained anytime and anywhere. Contribute to quick decision-making and problem response. Improve efficiency: Reduce the number of times operators need to frequently check the display screen of the machine itself. Multiple devices can be monitored at the same time. Data integration: terminal devices may have more powerful data processing and display capabilities. Data from multiple machines can be integrated together for more comprehensive analysis. Safety: in certain dangerous or inaccessible environments, the status of equipment can be safely monitored. Scalability: provides a basis for future upgrades and expansions of the system, such as adding remote control, data cloud storage and other functions. Convenient maintenance: technicians can diagnose problems remotely and provide timely support. Production management optimization: managers can more conveniently understand the production situation, optimize production plans and resource allocation. In general, this wireless communication function greatly enhances the system's monitoring capabilities and flexibility of use, making the entire production process more intelligent and information-based. It not only improves production efficiency, but also lays the foundation for further automation and intelligent management.

[0071] Furthermore, the system further comprises a comparison module 50 and a switch module 60;

[0072] The comparison module 50 is connected to the pressure acquisition module 10 and the switch module 60 respectively, and the switch module 60 is connected to the power supply and the material receiving and transferring mechanism respectively;

[0073] The pressure acquisition module 10 is also used to convert the pressure into a corresponding pressure electrical signal and transmit it to the comparison module 50;

[0074] The comparison module 50 is used to compare the voltage value corresponding to the pressure electrical signal with a preset voltage value, and output a conduction signal to the switch module 60 when the voltage value corresponding to the pressure electrical signal is greater than the preset voltage value;

[0075] The switch module 60 is used to conduct the connection between the power supply and the material receiving and transferring mechanism when receiving the conduction signal, so that the material receiving and transferring mechanism transfers the superimposed magnetized products to the PVC collection pipe.

[0076] It should be noted that the pressure acquisition module 10 converts the detected pressure into an electrical signal and transmits the electrical signal to the comparison module 50. The comparison module 50 receives the electrical signal from the pressure acquisition module 10, compares the voltage value corresponding to the electrical signal with the preset voltage value, and outputs a conduction signal to the switch module 60 if the voltage value of the electrical signal is greater than the preset voltage value. The switch module 60 receives the conduction signal from the comparison module 50, and when receiving the conduction signal, connects the power supply and the material receiving and transferring mechanism. The material receiving and transferring mechanism starts after the power is turned on, and transfers the magnetized products that have been stacked to the PVC collection pipe. Functional significance and advantages: a. Improved automation: The system can automatically determine whether the product stacking is completed, and the material receiving process can be started without manual intervention. b. Accurate control: The product stacking state is accurately determined by the pressure value, avoiding the errors that may be caused by human judgment. c. Improved efficiency: Reduced manual operation time, improved production efficiency and continuity. d. Improved safety: Reduced the frequency of manual contact with the equipment, and reduced operational risks. e. Controllable process: The timing of material receiving can be controlled by adjusting the preset voltage value to adapt to different product specifications and production requirements. f. Collaboration with other modules: Closely cooperate with the pressure acquisition module 10 to form a closed-loop control system. g. Flexibility: The preset voltage value can be adjusted as needed to adapt to different production needs and product characteristics. h. Quality control: Ensuring that each batch of products is stacked and transferred under the same conditions helps to maintain the consistency of product quality. The design of this functional module embodies the idea of ​​automation and intelligence. Through precise pressure detection and automatic control, the automatic material collection process after the product stacking is completed is realized. This not only improves production efficiency, but also ensures the consistency and reliability of the production process. It is an important part of the intelligence of the entire system.

[0077] Furthermore, the control system of the fully automatic shim adding magnetizing machine further includes: a voltage dividing module 70 and a voltage stabilizing module 80;

[0078] The voltage dividing module 70 is connected to the power supply and the voltage stabilizing module 80 respectively, and the voltage stabilizing module 80 is connected to the pressure acquisition module 10;

[0079] The voltage dividing module 70 is used to divide the power supply voltage provided by the power supply to obtain a divided voltage, and send the divided voltage to the voltage stabilizing module 80;

[0080] The voltage stabilization module 80 is used to stabilize the divided voltage and send the stabilized divided voltage to the pressure acquisition module 10;

[0081] The pressure acquisition module 10 is also used to adjust the divided voltage after stabilization to obtain the pressure electrical signal.

[0082] It should be noted that the voltage is reduced by voltage division to adapt to the working voltage requirements of different components, voltage stabilization ensures the stability of voltage, reduces the impact of power supply fluctuations on the system, and the voltage stabilization process reduces the interference of power supply noise on the signal, thereby improving the accuracy and reliability of the pressure electrical signal. Allow the system to use a standard power supply and adapt to the needs of different components through voltage division. Enhance the flexibility and adaptability of the system. Voltage division can reduce the working voltage of certain components and potentially reduce power consumption. Through precise voltage control, the accuracy of pressure acquisition is improved, which helps the precise operation of the entire system. The voltage division and voltage stabilization process can protect sensitive electronic components from damage by high voltage. The voltage stabilization process helps to offset external electromagnetic interference and improve system stability. The pressure acquisition module 10 can further adjust the stabilized voltage as needed, and can adapt to different types of pressure sensors and signal processing requirements. Stable power supply and signal processing help to improve the reliability and life of the entire system. The design of this functional module shows the careful consideration of the system in power management and signal processing. Through the combination of voltage division, voltage stabilization and signal conditioning, not only is it ensured that each part of the system obtains a suitable working voltage, but also the quality and reliability of the pressure signal are improved. This is crucial to the accuracy and stability of the entire control system, and is especially valuable in application scenarios that require high-precision pressure measurement.

[0083] Furthermore, the pressure acquisition module 10 includes: a first resistor R1, which is a piezoresistor;

[0084] The first end of the first resistor R1 is connected to the power supply through the voltage stabilizing module 80 and the voltage dividing module 70 , and the second end of the first resistor R1 is connected to the controller 20 and the comparison module 50 , respectively.

[0085] It should be noted that a varistor is a special resistor whose resistance value changes with the applied pressure. When the pressure increases, the resistance value usually decreases, and vice versa. This characteristic makes it an ideal pressure sensing element. A voltage divider circuit is formed. The varistor acts as a variable resistor. The pressure change causes the resistance value to change, which in turn causes the voltage distribution to change. Signal generation: pressure changes, resistance changes, voltage changes, and the voltage change is the pressure electrical signal. The generated pressure electrical signal is transmitted to the controller 20 and the comparison module 50 at the same time. The controller 20 may be used for data processing and system control. The comparison module 50 is used to compare with the preset value to determine whether a specific condition is met. Advantages and features: The varistor is very sensitive to pressure changes and can capture small pressure changes. It has a simple structure, reduces failure points, and improves the overall reliability of the system. Pressure is directly converted into an electrical signal without complex intermediate conversion steps. Different pressure ranges can be adapted by selecting varistor of different specifications. The varistor usually responds quickly to pressure changes, which is conducive to real-time control. At the same time, signals are provided to the controller 20 and the comparison module 50 to meet various processing requirements. The stability and accuracy of the signal are ensured by the cooperation of the voltage stabilization and voltage divider module 70. Compared with some complex pressure sensors, this design may be more cost-effective. The sensitivity and range can be adjusted by adjusting the circuit parameters. The structure is simple and easy to maintain and replace. This design cleverly utilizes the characteristics of varistors to directly convert mechanical pressure into electrical signals. By cooperating with the power management and signal processing modules described previously, a complete and efficient pressure acquisition system is formed. This not only ensures the accuracy and reliability of the pressure signal, but also provides a solid data foundation for the automatic control and intelligent decision-making of the system.

[0086] Further, the comparison module 50 comprises: a first comparator A1;

[0087] The positive input terminal of the first comparator A1 is connected to the second end of the first resistor R1 , the negative input terminal of the first comparator A1 is connected to a first preset reference power supply, and the output terminal of the first comparator A1 is connected to the switch module 60 .

[0088] It should be noted that the comparator compares the voltages of its two input terminals. When the voltage at the positive input terminal is higher than that at the reverse input terminal, a high level is output; otherwise, a low level is output. The pressure electrical signal generated by the varistor is used as the positive input of the comparator. The preset reference power supply provides a fixed reference voltage as a comparison benchmark. The comparator compares the two voltages in real time. When the pressure electrical signal exceeds the preset reference voltage, the comparator outputs a high level. This output signal is sent to the switch module 60. This design converts simple pressure detection into precise digital control signals, providing a key decision-making basis for the automated operation of the system. Through precise control and rapid response, it ensures the accuracy and efficiency of the production process and is an important link in the entire control system.

[0089] Furthermore, the switch module 60 includes: a first switch tube Q1 and a second resistor R2;

[0090] Among them, the first end of the second resistor R2 is connected to the power supply, the second end of the second resistor R2 is connected to the input end of the first switch tube Q1, the control end of the first switch tube Q1 is connected to the output end of the first comparator A1, and the output end of the first switch tube Q1 is connected to the material receiving and transferring mechanism.

[0091] It should be noted that the second resistor R2 is used as a current limiting element to control the current passing through the switch tube to prevent overcurrent damage. The function of the first switch tube Q1: The switch tube (which can be a transistor or MOSFET) is used to control a large current load, and determines whether the input end and the output end are turned on according to the voltage signal at the control end. When the first comparator A1 outputs a high level (indicating that the pressure exceeds the preset value), the control end of the first switch tube Q1 receives a high level signal, causing it to turn on. The power supply supplies power to the material receiving and conveying mechanism through the second resistor R2 and the turned-on switch tube. The material receiving and conveying mechanism starts to complete specific actions (such as conveying, receiving materials, etc.). This switch module 60 uses a simple and effective circuit, the switching characteristics of the switch tube and the current limiting effect of the resistor to achieve precise control of the material receiving and conveying mechanism. This design not only ensures the reliability and stability of the system, but also improves the efficiency of automated operation, and is a key link in the control system.

[0092] Further, the status display module 30 includes: a plurality of light emitting diodes;

[0093] The anode of each light emitting diode is connected to the controller 20 , and the cathode of each light emitting diode is grounded.

[0094] It should be noted that the role of the LED is to serve as a visual indicator to display different states or working modes of the system. The controller 20 controls the on and off of each LED by controlling the positive voltage of the LED. When the controller 20 outputs a high level to the positive electrode of the LED, the LED lights up; when it outputs a low level, the LED goes out. Multiple LEDs can display complex system states through different combinations. For example, LEDs of different colors can represent different working states (such as the number of stacked products to be magnetized) or warning messages.

[0095] Further, the voltage dividing module 70 includes: a third resistor R3 and a fourth resistor R4, and the voltage stabilizing module 80 includes: a first capacitor C1;

[0096] Among them, the first end of the third resistor R3 is connected to the power supply, the second end of the third resistor R3 is connected to the first end of the fourth resistor R4, the first end of the fourth resistor R4 is also connected to the first end of the first resistor R1 and the first end of the first capacitor C1, and the second end of the fourth resistor R4 and the second end of the first capacitor C1 are grounded.

[0097] It should be noted that the third resistor R3 and the fourth resistor R4 form a voltage divider circuit. The power supply voltage is stepped down through the third resistor R3, and the voltage is transmitted from the second end of the third resistor R3 to the first end of the fourth resistor R4. The output voltage of the voltage divider circuit (the voltage at the second end of the fourth resistor R4) can be set by adjusting the resistance values ​​of the third resistor R3 and the fourth resistor R4. The function of the first capacitor C1 is to filter and stabilize the voltage. The capacitor is connected between the fourth resistor R4 and the ground, which helps to smooth the voltage and reduce the impact of power supply fluctuations or noise on the circuit. The characteristics of capacitor charging and discharging can reduce voltage fluctuations, making the voltage passing through the fourth resistor R4 more stable, and providing a stable reference voltage.

[0098] It should be noted that, in this article, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or system including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or system. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the existence of other identical elements in the process, method, article or system including the element.

[0099] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
