[0002] Four-button is a kind of button, usually referred to as button, spring button or sewing button. It includes female button and male button, female button usually has decorative pattern and has a central hole and two parallel springs;Male button protrudes a dot in the center, after pressing into the female button hole, the spring clamps the dot, thereby generating fixing force.

[0003] The current control system mainly relies on independent PLC, servo driver and step driver, these components work cooperatively under the control of PLC through pulse signals to drive servo motor and step motor to operate. At the same time, each air valve also needs to be wired to PLC for control. PLC system displays operating status and configures parameters through communication connection with human-machine interface configuration screen. In this system, cloth is first pre-punched with a through hole by punch and punch eye die to provide space for button pressing and ensure that the cloth will not wrinkle when buckling. Then, the upper and lower buttons are sent into the track by the vibration disc, and the buttons are blown into the waiting button position from the track by airflow. Then, the buttons are sent into the upper and lower molds by the upper and lower button feeding valves, ready for pressing.

[0035] The current control system mainly relies on PLC, servo driver, step driver and air valve to work cooperatively, and is responsible for driving machine operation. The cloth is punched through the hole by the punch and die, and the button is sent into the track and die for pressing by the vibrating disc 50. The system structure is complex, the wiring is numerous, which leads to high cost and difficult assembly and maintenance, and is not suitable for large-scale production. The vibrating disc 50 control needs to install an additional controller, and the vibration intensity can only be adjusted by an external knob, and cannot be uniformly controlled with the HMI configuration screen. Overall, the operation is complex and inconvenient, and needs to be improved to improve the production efficiency.

[0036] To this end, the utility model provides a button sewing machine control system, solves the problem of high cost, complicated wiring, difficult maintenance and insufficient integration of existing control system, realizes the improvement of efficiency, cost reduction and adaptation to the demand of large -scale production.

[0037] Specifically, the system simplifies the structure of the original system by integrating the main controller 10, motor drive unit, vibration disc drive unit and bus valve island 20, reduces multiple independent control modules and improves the integration of the system.

[0038] The system designs a zero-crossing power-down detection circuit to ensure stable operation of the system in the case of power failure or power fluctuation, improve the reliability and maintainability of the system; the motor drive unit adopts a servo motor 30 drive chip and an overcurrent detection resistor to optimize the motor 30 control, improve the control accuracy and response speed, and reduce the energy consumption of the system; the combination of the encoder communication circuit and the motor 30 realizes accurate motor 30 position feedback, improves the control accuracy and reliability of the system, and avoids complex mechanical adjustment; the vibration disc drive unit is simplified by the cooperation of the light-controlled silicon trigger and the silicon-controlled silicon, which reduces the wiring complexity and improves the control accuracy and efficiency; the system integrates the lighting lamp and the input port 60 to enhance the operation convenience and visualization, reduce the working intensity of the operator, and adapt to the demand of large-scale production.

[0039] In order to better understand the above technical scheme, the above technical scheme will be described in detail in combination with the description of the drawings and the specific embodiments.

[0040] Please refer to Figure 1 , button sewing machine control system, comprising: main controller 10, bus valve island 20, motor 30, display screen 40 and vibration disc 50, main controller 10 includes main control unit, motor drive unit and vibration disc drive unit, bus valve island 20, motor drive unit, vibration disc drive unit and display screen 40 are connected with main control unit respectively.

[0041] In this embodiment, a highly integrated, easy-to-maintain and cost-effective solution is provided. The system integrates various functional components, including main controller 10, bus valve island 20, motor 30 (upper die motor, lower die motor), display screen 40 and vibration disc 50 (left vibration disc and right vibration disc), etc., forming a compact and efficient automated platform.

[0042] The main controller 10 serves as the command center of the entire system, responsible for coordinating and managing all external devices connected to it. It not only provides power supply to all external devices, but also achieves foolproof function through carefully designed terminal layout, ensuring correct installation. To adapt to the needs of different types of users, the up and down mold motor 30 interface is designed with the same specifications, making it easy to replace with a servo motor 30 or a stepper motor 30 in the future. The built-in high-performance M4 core microcontroller, also known as the main control unit.

[0043] The manifold valve island 20 integrates multiple key valves (such as anti-punching valve, mobile up sending buckle valve, down sending buckle valve, taking buckle valve, up blowing valve, down blowing valve, flushing eye mold control valve, clamping buckle valve), and the wiring of these valves is concentrated in a DB15 interface, simplifying the wiring complexity and improving the maintainability of the system.

[0044] The main control unit can directly drive a servo motor 30 and a closed-loop stepper motor 30. This feature enables the button machine to perform well in precise position control while maintaining high efficiency.

[0045] In addition, it also contains an AC zero-crossing detection circuit and a dedicated vibration disc 50 drive circuit, which can be directly connected to the vibration disc 50 and can adjust the working intensity of the vibration disc 50 through the communication interface on the HMI display screen 40. This design reduces the need for external wiring and improves the overall reliability of the system.

[0046] It is equipped with a multifunctional HMI display screen 40, which supports USB interface for upgrading the controller program in addition to the regular configuration screen display control. This feature not only facilitates operators to monitor the machine status, but also facilitates technical personnel to update software and provide technical support.

[0047] All control logic, drivers, and power management are integrated into a single main controller 10, with external fast connectors for plug-and-play. By concentrating all valve wiring in a DB15 interface and using a unified motor 30 interface, the on-site installation and troubleshooting process is greatly simplified. Different motor 30 type conversion is supported to meet diverse application scenarios; and firmware upgrade can be easily completed through the USB interface, maintaining the advanced nature and compatibility of the system. While ensuring performance, the hardware structure is optimized to reduce costs and improve market competitiveness.

[0048] In summary, the button machine control system, through its innovative architectural design and advanced technology application, realizes efficient, stable, and flexible operation experience, and is an indispensable part of modern manufacturing industry.

[0049] In an embodiment, please refer to Figure 2 and Figure 6The main controller 10 further comprises a zero-crossing power-off detection circuit.

[0050] In an embodiment, referring to Figure 2 The zero-crossing power-off detection circuit comprises a voltage dividing circuit, a rectifier circuit and an opto-isolator U37. The voltage dividing circuit is connected to the rectifier circuit, the rectifier circuit is connected to the opto-isolator U37, and the opto-isolator U37 is connected to the main control unit.

[0051] In this embodiment, the zero-crossing power-off detection circuit is designed to ensure that in the event of sudden interruption of the AC power supply or voltage drop to insufficient to maintain the normal operation of the system, the protection measures can be taken in time. Specifically, when the external AC input stops, the bus voltage relies on the internal capacitor to maintain the power supply of the system. With the passage of time and the power consumption of the system, the bus voltage gradually decreases. There is a pressure difference of more than 100 volts from the power-off to the time when the system cannot work at low voltage. Since too low voltage will cause the motor 30 to be unable to run, it is necessary to execute the motor 30 action in the first time to make it return to the safe state; then control the action of each valve according to the constraint relationship between components; at the same time, data storage is carried out to save the current real-time data and prevent important information from being lost.

[0052] In this embodiment, the zero-crossing power-off detection circuit is designed as follows:

[0053] Voltage dividing circuit: composed of resistors R142, R143, R148, R149 and R154 in series, used to monitor the voltage change between AC_L and AC_N.

[0054] Rectifier circuit: through diodes D15~D18, the rectifier circuit rectifies the AC signal after voltage division to ensure the output of stable DC level.

[0055] Energy storage element: C147 capacitor is charged to about 15V after rectification, as the basis for subsequent logic judgment.

[0056] Trigger mechanism: when the voltage between AC_L and AC_N is zero, C147 capacitor makes the triode Q4 conduct through R154 resistor, and C147 also makes the opto-isolator U37 conduct through R156. This step makes the AC_ZERO network output a narrow pulse width zero-crossing signal, which is transmitted to the main control unit as the detection basis of the power-off signal.

[0057] In summary, the zero-crossing power-down detection circuit not only realizes the accurate capture of the zero-crossing point of the AC power supply voltage, but also can quickly respond in abnormal power supply conditions, ensuring the stability and safety of the system. This design ingeniously combines techniques such as voltage division, rectification, energy storage, and opto-isolation, providing solid technical support for implementing efficient and reliable power-down protection.

[0058] In an embodiment, referring to Figure 3 The motor driving unit described above includes a servo motor 30 driving chip U23, an overcurrent detection resistor R102, and a low-pass filter circuit. The servo motor 30 driving chip U23 is connected to the overcurrent detection resistor R102. The overcurrent detection resistor R102 is connected to the low-pass filter circuit. The servo motor 30 driving chip U23 is connected to the main control unit.

[0059] Specifically, Figure 3 The servo motor 30 driving chip U23 is mainly controlled by the PWM signal output by the main control unit, which in turn drives the motor 30 to operate. The circuit includes key components such as overcurrent detection, filter circuit, and bootstrap capacitor.

[0060] The main control unit outputs 6-way PWM control signals:

[0061] High-side drive signals: HP_PWM1_UH, HP_PWM1_VH, HP_PWM1_WH;

[0062] Low-side drive signals: HP_PWM1_UL, HP_PWM1_VL, HP_PWM1_WL;

[0063] These signals are sent to the servo motor 30 driving chip U23 to control the operation of the motor 30.

[0064] After the servo motor 30 driving chip U23 receives the PWM signal, it generates power output to drive the motor 30 to operate.

[0065] The servo motor 30 driving chip U23 contains high-side and low-side power tubes inside, which control the on-off of the motor 30 through these PWM signals.

[0066] R102 is an overcurrent detection resistor. When the voltage across it is greater than 0.5V, it indicates that an overcurrent condition has occurred.

[0067] At this time, the HP_VFO1 network of the servo motor 30 driving chip U23 will output a low-level signal, notifying the main control unit to turn off the PWM control signal to protect the system from overcurrent damage.

[0068] R100 and C97 form a low-pass filter circuit to avoid false actions caused by glitches on R102.

[0069] The filter circuit ensures the accuracy of the overcurrent detection signal and prevents false triggering of the protection mechanism.

[0070] C99, C100, C101 are bootstrap capacitors inside the servo motor 30 drive chip U23.

[0071] These capacitors bootstrap the 15V drive voltage to the bus voltage range for driving the internal high-side power tube.

[0072] The PWM signals (HP_PWM1_UH, HP_PWM1_VH, HP_PWM1_WH and HP_PWM1_UL, HP_PWM1_VL, HP_PWM1_WL) output by the main control unit are connected to the corresponding inputs of the servo motor 30 drive chip U23. These signals control the operation of the motor 30 through the high-side and low-side power tubes inside the IPM module. R102 is an overcurrent detection resistor connected in series in the current path. When the current is too large and the voltage across R102 exceeds 0.5V, the HP_VFO1 network of the servo motor 30 drive chip U23 will output a low-level signal.

[0073] This signal is transmitted to the main control unit through an optical coupler isolator. Upon receiving the signal, the main control unit immediately turns off the PWM control signal and stops the motor 30 from running. The low-pass filter circuit composed of R100 and C97 is located after the overcurrent detection circuit. This filter circuit can effectively remove the glitch signal on R102, ensuring the accuracy and reliability of the overcurrent detection signal. C99, C100, C101 are bootstrap capacitors that raise the 15V drive voltage to the bus voltage range. These capacitors ensure the normal operation of the high-side power tube inside the servo motor 30 drive chip U23 and provide a stable drive voltage.

[0074] The servo motor 30 drive chip U23 is controlled by the PWM signal output by the main control unit, achieving precise control of the motor 30. At the same time, the circuit contains an overcurrent detection and filter circuit, ensuring the stability and safety of the system. The bootstrap capacitors ensure the normal operation of the high-side power tube inside the servo motor 30 drive chip U23 and provide a reliable drive voltage.

[0075] In an embodiment, please refer to Figure 4 The above-mentioned main controller 10 further comprises an encoder communication circuit, which is connected with the main control unit and the encoder respectively, and the encoder is connected with the motor 30.

[0076] In an embodiment, please refer to Figure 4 The above-mentioned encoder communication circuit comprises a communication chip U11, which is connected with the main control unit and the encoder respectively.

[0077] The communication chip U11 is an SP3485EN chip, which is used to realize RS485 communication.

[0078] The pin description is as follows:

[0079] PIN 1: ENC1 RX (receive signal);

[0080] PIN 2: RO (output enable);

[0081] PIN 3: REDE (receive enable);

[0082] PIN 4: ENC1 TX (transmit signal);

[0083] PIN 5: DI (data input);

[0084] PIN 6: DE (drive enable);

[0085] PIN 7: A (differential signal A);

[0086] PIN 8: B (differential signal B);

[0087] The +3.3V power supply provides stable power supply through R198 and C175. C175 is a decoupling capacitor used to filter power supply noise. D20 is an ESD protection diode used to prevent communication port damage caused by inrush and static electricity during hot plug. T2 is a common mode inductor used to filter external common mode interference and improve communication anti-interference ability.

[0088] The pre-pull-up resistors R57, R58, and R59 are used to set the pre-pull-up resistors of the RS485 bus. These resistors maintain the bus state during communication idle to avoid external interference causing communication errors.

[0089] C58 and C60 are both capacitors used to filter high-frequency noise and ensure signal stability.

[0090] +3.3V power supply is provided through R198 (5.1KΩ) and C175 (0.1μF). C175 acts as a decoupling capacitor, filtering out power supply noise to ensure the stable operation of the SP3485EN chip. PIN 1 and PIN 4 of the communication chip U11 are connected to ENC1 RX and ENC1 TX, respectively, for receiving and transmitting signals. PIN 7 and PIN 8 are connected to differential signals A and B, respectively, for differential transmission. D20 is an ESD protection diode connected between differential signals A and B to prevent damage to the communication port caused by inrush and static electricity during hot plug. T2 is a common-mode inductor connected between differential signals A and B to filter out external common-mode interference and improve the anti-interference capability of communication. R57 and R59 are 330Ω resistors connected to differential signals A and B to set the pre-pull-up and pre-pull-down resistors of the RS485 bus. These resistors maintain the bus state during communication idle to avoid communication errors caused by external interference. C58 and C60 are both 1nF capacitors connected to differential signals A and B to filter out high-frequency noise and ensure signal stability.

[0091] Figure 4 A complete RS485 communication circuit is demonstrated, which realizes communication with the servo motor 30 encoder through the SP3485EN chip. The circuit contains key components such as ESD protection devices, common-mode inductors, and pre-pull-up and pre-pull-down resistors to ensure the stability and reliability of communication.

[0092] In an embodiment, referring to Figure 5 The above-mentioned vibration disc driving unit includes a triac trigger U35 and a triac T5; the triac trigger U35 is connected with the main control unit; the triac trigger U35 is connected with the triac T5, and the triac T5 is connected with the vibration disc 50.

[0093] The triac trigger U35 is an MOC3023 optocoupler, which is used to isolate and transmit the control signal of the main control unit to the high-power triac T5. The optocoupler contains a light-emitting diode and a photosensitive transistor inside, achieving electrical isolation.

[0094] The high-power triac T5 is a BTA16-600BWRG high-power triac, which is used to control the on-off of the high-voltage AC power supply. The triac is turned on or turned off by the trigger signal of the optocoupler.

[0095] R150 and R145 form an RC absorption circuit, which is used to absorb the voltage spike generated when the triac is turned off. The combination of these resistors and capacitors can effectively suppress the voltage spike and prevent the triac from being misdirected.

[0096] R138 is a 330Ω resistor used to limit the current at the input of the optocoupler. C143 is a decoupling capacitor used to filter power supply noise. R146 is a 390Ω resistor used to limit the current. C145 is a 10μF / 2kV capacitor used for energy storage and filtering. R144 is a 390Ω resistor used to limit the current.

[0097] The control signal output by the master control unit is connected to the input of the optocoupler U35 through TP17. When the master control unit outputs a high level, the light-emitting diode inside the optocoupler is turned on, triggering the phototransistor to turn on. After the phototransistor is turned on, a trigger signal is provided to the high-power thyristor T5. After the high-power thyristor T5 receives the trigger signal from the optocoupler U35, it is turned on, controlling the on-off of the high-voltage AC power supply. When the thyristor is turned on, the high-voltage AC power supply flows through the thyristor to the load.

[0098] R150 and R145 form an RC absorption circuit connected between the anode and cathode of the thyristor. When the thyristor is turned off, the RC absorption circuit absorbs the voltage spike generated to prevent the thyristor from being mistakenly turned on.

[0099] The control signal of the master control unit is isolated and transmitted to the high-power thyristor T5 through the optocoupler U35. The RC absorption circuit (R150, R145) is used to absorb the voltage spike generated when the thyristor is turned off, ensuring the stable operation of the thyristor. Other components such as resistors and capacitors are used for current limiting, filtering and energy storage, ensuring the reliability and stability of the entire circuit.

[0100] In an embodiment, referring to Figure 1 The above-described button sewing machine control system further includes a lighting lamp connected to the master control unit.

[0101] In an embodiment, referring to Figure 1 The above-described button sewing machine control system further includes an input port 60 connected to the master control unit.

[0102] In an embodiment, the above-described bus valve island 20 includes a hand protection valve, a moving up button valve, a down button valve, a button taking valve, an upper air blowing valve, a lower air blowing valve, a punch hole mold control valve, and a button clamping valve.

[0103] In this embodiment, a master control unit is provided in the system, which is responsible for managing the on-off operation of all valves. The master control unit determines the valves that need to be actuated through internal logic and issues corresponding control instructions.

[0104] Instead of being individually connected to the master control unit, each valve is aggregated through a concentrator or bus valve island 20. This has the advantage of reducing the number of physical connections between the valves and the master control unit, reducing installation complexity and failure rate.

[0105] In the control circuit of each valve, an indicator light is added, which corresponds to the corresponding valve one by one. When a certain valve is activated, its associated indicator light will also light up, making it easy for the operator to quickly locate the working state or troubleshoot problems.

[0106] In some embodiments, as shown in Figure 1 , the button sewing machine control system is also equipped with a lighting lamp. The lighting lamp is directly connected to the master control unit and can be controlled by the master control unit according to actual needs (such as insufficient ambient light). This design not only improves the safety of operation, but also provides the necessary visual aid in night or low light conditions.

[0107] As can also be seen in Figure 1 , the system also contains an input port 60. The input port 60 is also connected to the master control unit, allowing external devices or sensors to access the system. For example, it can be used to receive status signals from sensors or as part of a human-machine interface for manual control.

[0108] As shown in Figure 9 , the manifold valve island 20 refers to a modular component that integrates multiple valves with similar or related functions.

[0109] In this case, the manifold valve island 20 contains the following types of valves:

[0110] Anti-hand valve: used to protect the safety of the operator.

[0111] Moving up and down feeding valves: responsible for material transportation in the up and down directions, respectively.

[0112] Take-off valve: used to take out finished products or waste materials.

[0113] Up and down blowing valves: used to clean the work area or push the material.

[0114] Punching eye mold control valve: used to control the action of a specific mold.

[0115] Clamping valve: used to fix or release the workpiece.

[0116] In summary, the button sewing machine control system achieves the goals of simplifying the wiring structure, enhancing the convenience of operation and the convenience of maintenance through optimizing the valve layout, introducing centralized control and indicator lights, etc. At the same time, the additional lighting lamp and input port 60 further improve the flexibility and practicality of the system.

[0117] In an embodiment, as shown in Figure 7As shown, the display screen 40 uses a USB connection to upgrade the system, specifically using the OTG protocol for upgrading. OTG (On-The-Go) is an extension of the USB standard that allows USB devices to communicate directly with each other without the need for a traditional host computer (such as a personal computer). With the OTG function, a device can dynamically switch between host and slave roles, greatly enhancing the flexibility of data exchange between portable devices.

[0118] Specifically, the user first needs to obtain the latest system upgrade files. These files are copied to an OTG-compatible storage medium, such as a USB flash drive.

[0119] The USB flash drive containing the upgrade files is connected to the target device via an OTG cable. After the device restarts, the built-in display screen 40 automatically scans the contents of the USB flash drive. The system checks whether there are upgrade codes or firmware images that meet the format requirements in the USB flash drive.

[0120] Once the presence of valid upgrade files is confirmed, the device will prompt the user to start the upgrade process. The user can choose whether to upgrade immediately. If the user chooses to continue, the device will complete the firmware or software update operation according to the predetermined procedure.

[0121] After the upgrade is complete, the system will display the corresponding status information on the screen, informing the user whether the upgrade was successful. If any problems are encountered, detailed error reports will also be provided for further processing.

[0122] Not only does this simplify the process of firmware updates that traditionally rely on a computer, but it also makes it easy for non-technical personnel to maintain and upgrade the device. At the same time, it reduces the need for additional hardware or network connections, improving the efficiency of on-site deployment and maintenance. In addition, this solution is also suitable for applications that may not have stable internet access environments.

[0123] By detecting power failure, the external power supply is disconnected, and when the internal power supply can still maintain operation, the components are quickly returned to their original positions according to the constraints. Before power failure, parameters are saved to ensure that real-time data is not lost. Using OTG for upgrading allows for easy subsequent function upgrades or code upgrades, as long as the code is sent to the user and copied into the USB flash drive for upgrading.

[0124] The button sewing machine control system reduces the number of independent modules, reduces the complexity of the system and the wiring difficulty by integrating the main controller 10, the motor driving unit, the vibration disc driving unit and the bus valve island 20 together; the main controller 10 includes the independent driving units of the motor 30 and the vibration disc 50, simplifies the motor 30 control and the vibration disc 50 adjustment process, reduces the hardware cost and the system maintenance difficulty; the various key components of the system such as the bus valve island 20, the motor driving unit and the like are directly connected with the main control unit, centralized control is realized, the control precision and the response speed are improved; the integration of the display screen 40 makes the operation interface more intuitive, simplifies the operation process, improves the production efficiency, and at the same time reduces the failure rate caused by the complicated wiring; the design adapts to the large-scale production demand, through the integration and the optimized design, the efficient operation, the low maintenance requirement of the system are ensured, and the overall cost of the system is effectively reduced.

[0125] The above merely illustrates the specific implementation of the present application, but the protection scope of the present application is not limited to this, any skilled person in the art can easily think of various equivalent modifications or replacements within the technical range disclosed by the present application, and these modifications or replacements should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
