Description

Technical Field

[0001] This invention belongs to the field of safety control technology for stamping equipment, and particularly relates to a method, system and device for safety reset of stamping line grating based on sequential button confirmation. Background Technology

[0002] ADC is an abbreviation for "Automatic Die Change," an automated process mode in stamping production lines. In this mode, the stamping press needs to change dies, typically involving a tooling cart entering and leaving the work area. Personnel may need to enter the protected area for auxiliary operations or inspections, thus the original safety grating protection may be temporarily disabled or require re-verification. In other words, when a dangerous intrusion is detected, the system immediately triggers the ADC die-changing mechanism for emergency shutdown to prevent personnel injury, making it a key component of stamping line safety protection.

[0003] In the related technology of the stamping line grating reset process, the automatic mold changing condition verification is based on the status of the main equipment such as the press. It is easy to start the reset under unsafe environmental conditions, such as the locking status of the mold changing device, the return status of the conveying mechanism, and obstacles in the working area, which may cause accidents such as mold collision and tooling damage.

[0004] Operators may press multiple buttons from the same location, leading to obstructions such as tools and parts not being cleared in time within the protected area. This can cause jamming or damage to equipment during subsequent operation. Conversely, excessively long disabling times can delay subsequent production processes, while excessively short disabling times may trigger the light curtain alarm before the operator has completely left the area, interrupting the reset process and impacting work efficiency.

[0005] The reset process lacks coordination with the main control panel of the stamping line. After the reset is completed, the status needs to be reported to the main control panel before subsequent production operations can be unlocked. The untimely feedback will lead to a longer production interruption time and affect the production capacity. Summary of the Invention

[0006] This invention provides a safety reset method for a stamping line grating based on sequential button confirmation. It forces operators to confirm the safety of the area point by point along a prescribed route. By combining button layout, time constraints and dynamic start and stop of the grating, it effectively prevents accidental entry, skipping steps or illegal reset.

[0007] The methods include:

[0008] S101. Check whether the automatic mold changing condition corresponding to the grating reset of the stamping line is met; if not, wait until the condition is met; if it is met, proceed to step S102.

[0009] S102: In response to the operator pressing the first reset button, the inlet grating, the protection grating and the outlet grating corresponding to the first reset button are activated simultaneously, the indicator light of the first reset button is set to a constant-on state, and the first confirmation button is put into a flashing state and the timer is started.

[0010] S103: In response to the operator pressing the first confirmation button within a preset time range, control the indicator light of the first confirmation button to switch to a constant-on state, and cause the next sequential second confirmation button to enter a flashing state and start the timer;

[0011] S104: Repeat step S103 to respond to the press of each sequential confirmation button in turn until the press of the last intermediate confirmation button is responded to.

[0012] S105: In response to the last intermediate confirmation button being pressed, the control exit grating enters a disabled state for a predetermined time;

[0013] S106: Reactivate the exit light grid in response to the operator pressing the exit reset button while the exit light grid is in a disabled state;

[0014] S107: Continue to respond to the press operations of each subsequent confirmation button in sequence until the press operation of the final reset button at the main control panel is responded to;

[0015] S108: In response to the final reset button being pressed, the grating reset process on one side of the stamping line is completed.

[0016] Preferably, S101 specifically includes the following steps:

[0017] The controller sends self-test commands to each monitoring area of ​​the grating protection device and collects power supply status and signal transmission integrity data for each area.

[0018] The controller retrieves the current operating mode data stored in the stamping line control system to determine whether it belongs to the mode category that allows grating reset;

[0019] The controller integrates environmental monitoring data from the monitoring unit with real-time occlusion signals from the grating to determine whether there are safety risks from personnel or obstacles within the protected area.

[0020] Preferably, S102 specifically includes the following steps:

[0021] The controller retrieves the address of the grating group corresponding to the first reset button, outputs a high-level drive signal to the power control circuit of the input grating, protection grating and output grating corresponding to that address, starts the infrared beam function of the grating, and triggers the fault self-diagnosis module of the grating.

[0022] The controller sends an activation command to the control relay of the first reset button indicator light, closing the power supply circuit of the indicator light and causing the indicator light to be powered on and illuminate.

[0023] The controller retrieves the preset flashing frequency parameters and outputs a pulsed level signal to the first confirmation button indicator light, triggering the operation timing module to start timing by calling the preset time parameters corresponding to the confirmation button.

[0024] Preferably, S103 specifically includes the following steps:

[0025] The controller receives the press signal of the first confirmation button, retrieves the data of the timing module corresponding to the first confirmation button, and compares whether the signal trigger time is within the preset time range; it then starts the level detection submodule to detect the duration of the continuous high level of the signal and filters valid operation signals.

[0026] The controller stops outputting pulse level signals to the first confirmation button indicator and switches to a continuous high level signal, closing the power supply circuit for the indicator; the operation status of the button is marked as completed and stored in the register;

[0027] The controller retrieves the next sequential button corresponding to the first confirmation button from the sequence button mapping table, which is the address of the second confirmation button, and outputs a pulse level signal of preset frequency to the indicator light corresponding to the address of the second confirmation button; it also starts the timing module corresponding to the button, loads the preset time parameters, and begins timing.

[0028] Preferably, S104 specifically includes the following steps:

[0029] The controller reads the confirmation button identifier of the completed operation from the register, starts the loop trigger mode, uses the current completion identifier as an index, and retrieves the address of the next confirmation button to be operated from the sequence button mapping table;

[0030] The controller continuously collects signals from the confirmation button, synchronously calls the timing module data corresponding to the confirmation button, and repeatedly performs signal validity and timeliness verification.

[0031] After the controller completes the operation status flag of a confirmation button, it retrieves the preset last intermediate confirmation button identifier and compares it with the currently completed button identifier. If they do not match, it returns to step S1041; if they match, it terminates the loop triggering mode.

[0032] Preferably, S105 specifically includes the following steps:

[0033] The controller reads the operation completion signal from the last intermediate confirmation button, verifies the validity of the signal level and the integrity of the signal transmission link, and retrieves the operation status of all previous intermediate confirmation buttons from the register.

[0034] The controller outputs a low-level cut-off signal to the power control circuit of the exit grating, disconnects the power supply link of the exit grating, and sends an exit grating disabled status signal to the human-machine interaction unit.

[0035] The controller activates the disable timing module corresponding to the disable of the exit light grid, loads the preset disable time parameters, and collects the power status signal of the exit light grid in real time to monitor the disable status.

[0036] Preferably, S106 specifically includes the following steps:

[0037] The controller receives the trigger signal from the exit reset button, verifies the duration of the signal's continuous high level to filter valid operations, reads the remaining duration of the exit grating's disable timing module to confirm that the operation occurred during the disable period, and collects the voltage signal of the exit grating's power supply circuit to verify that it is indeed in a disabled state.

[0038] The controller outputs a high-level drive signal to the power control circuit of the exit grating, closes the relay contacts of the power supply circuit, and restores power supply to the transmitter and receiver of the exit grating; it also sends the exit grating activation status code to the human-machine interface unit.

[0039] The controller initiates the exit grating activation status detection process, receives the working status signal fed back by the grating self-diagnosis module, sends a stop counting command to the disable timing module, and updates the status flag of the exit grating in the register.

[0040] Preferably, S108 specifically includes the following steps:

[0041] The controller receives the trigger signal from the final reset button, verifies the signal's amplitude and duration to confirm the operation's validity, and traverses the registers to check the operation status of all confirmation and reset buttons on one side, as well as the activation status of the inlet grating, protection grating, and outlet grating.

[0042] The controller outputs a stop signal to the warning unit, cuts off the power supply circuit of the strobe light, uniformly switches the working status of all button indicator lights on one side, and also sends a reset process completion status code to the human-machine interaction unit;

[0043] The controller writes the status information of the single-sided grating reset completion to the storage unit and generates a reset process completion report; it sends a process unlock signal to the stamping line control panel to allow the start of subsequent production-related operations.

[0044] According to another embodiment of this application, a stamping line grating safety reset system based on sequential button confirmation is provided. The system includes: a grating protection device, a reset button group, a controller, a monitoring unit, an alarm unit, and a human-machine interaction unit.

[0045] The grating protection device is used to detect and upload fault information to the controller in real time. The grating protection device includes an entrance grating, a protective grating and an exit grating set along the periphery of one side of the stamping line. Each set is an infrared through-beam safety light curtain.

[0046] The reset button group includes a first reset button, multiple sequential confirmation buttons, an exit reset button, and a final reset button arranged in sequence. All buttons are equipped with indicator lights and are installed at a specified height. The sequential confirmation buttons are distributed along the safety passage.

[0047] The controller is used to control the state of the grating and indicator lights in response to button signals. When the buttons are triggered in a preset sequence and within a valid time, the process is advanced; otherwise, the process is terminated and the system is locked.

[0048] The monitoring unit includes a high-definition camera, a recorder, and a central control console monitor, which provides real-time images during the reset process to assist operators in confirming safety.

[0049] The warning unit includes a strobe light installed on top of the grating protective cover, which is activated by the controller when the grating is activated and stops when it is reset or when an obstruction is detected, to warn that entry is prohibited;

[0050] The human-machine interface unit (HMI) is configured for the central control console to display the raster status, button records, step numbers, timing information, and fault prompts in real time.

[0051] According to another embodiment of this application, an electronic device is also provided, including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the program to implement the steps of the stamping line grating safety reset method based on sequential button confirmation.

[0052] As can be seen from the above technical solutions, the present invention has the following advantages:

[0053] The stamping line grating safety reset method provided by this invention adopts a pre-condition judgment approach. The controller synchronously collects the status signals of the mold changing device, conveying mechanism, and press, and combines them with the area obstacle detection data of the monitoring unit and the mode instructions and permission information of the human-machine interaction unit to form an automatic mold changing condition verification method. The layout design and control method of the reset button group are optimized. By setting the minimum spacing between adjacent confirmation buttons, the operator is forced to move to complete the operation. Based on the sequential button mapping table and indicator light status switching, the operator is guided to advance along a preset route, ensuring that each step of the operation is accompanied by a safety check of the corresponding area. A dedicated timed disable and activate control for the exit grating is designed. The operation signal of the last intermediate confirmation button is used as the trigger condition to start an independent high-precision timing module to control the disable duration. The exit grating is only reactivated when the operator presses the exit reset button and is within the disable time period. The level amplitude and duration of the operation signal are physically detected, and the time validity of the operation is determined by combining the data from the timing module, filtering out invalid signals that interfere with the process. An industrial bus communication link is established between the reset process and the main control panel of the stamping line. After the reset is completed, the controller automatically sends an unlock signal carrying the area identifier to the main control panel, realizing the automatic connection between the reset process and the production process. The operation status of each button, the working status of the grating, and the process progress are fed back in real time through the human-machine interface unit, and all node data is written to the storage unit.

[0054] To more clearly illustrate the technical solution of the present invention, the accompanying drawings used in the description will be briefly introduced below. Obviously, the accompanying drawings described below are only some embodiments of the present invention.

[0058] Figure 4 This is a schematic diagram of an electronic device. Detailed Implementation

[0059] The stamping line grating safety reset method provided by this invention is based on a stamping line grating safety reset system. Figure 1 As shown, the system includes a grating protection device, a reset button group, a controller, a monitoring unit, an alarm unit, and a human-machine interaction unit. The units work together to control the grating reset.

[0060] Specifically, the light curtain protection device is based on setting up three sets of infrared through-beam safety light curtains along one side of the stamping line, namely the workbench and tooling travel area. These are the entrance light curtain, the protection light curtain, and the exit light curtain, each corresponding to an independent monitoring area. The light curtain response time is ≤10ms, and the protection height is adjustable from 0.8 to 1.5m. It has a fault self-diagnosis function, which can detect the power supply status and signal integrity of the transmitter and receiver in real time and upload the fault information to the controller. It is synchronously activated in step S102, the exit light curtain is temporarily de-energized and disabled in step S105, and is reactivated by the controller in step S106.

[0061] Reset button group: includes a first reset button, multiple sequential confirmation buttons (from the first confirmation button to the last intermediate confirmation button), an exit reset button, and a final reset button.

[0062] All buttons are installed at a height of 1.2–1.4m. The sequential confirmation buttons are distributed along the safety passage of the stamping line at the main and auxiliary operating stations, with a horizontal spacing of ≥2.5m between adjacent buttons to ensure that operators must walk to trigger them sequentially. The first reset button is located on the outer guardrail of the light-grate entrance, the exit reset button is located outside the exit area and cannot be reached from inside the fence, and the final reset button is located on the main control panel. Each button integrates an indicator light, whose on / off state is controlled by the controller according to the stamping line light-grate safety reset method, used to guide the operation process and provide feedback on the current reset stage.

[0063] The controller uses an industrial-grade safety PLC (such as the Siemens S7-1500F series), with a built-in reset safety verification module, sequential logic judgment module, and high-precision timer; it performs automatic mold change condition detection. In the stamping line grating safety reset method, it responds to each button trigger signal to control grating activation / deactivation, indicator light state switching, strobe light start / stop, and timer start / stop; the process is only allowed to proceed when the buttons are triggered in a preset sequence and within the valid time point; if timeout, skipping, or illegal intrusion is detected, the reset is immediately terminated and the system is locked.

[0064] The monitoring unit consists of high-definition cameras, recorders, and central control monitors deployed in key areas of the stamping line. During the reset process, operators can view the inside and outside of the protected area in real time through the monitors, assisting in completing safety confirmations. It provides visual support for manual safety checks in the stamping line's grating safety reset method, ensuring that there are no remaining obstacles or personnel in the area.

[0065] The warning unit includes a strobe light mounted on top of the grating protective cover; the controller activates the strobe light simultaneously with the global grating to warn other personnel not to enter; the strobe light continues to operate until the reset process is interrupted or the grating detects obstruction, causing the process to terminate. The start / stop status is directly controlled by the controller and is synchronized with the reset process lifecycle.

[0066] The human-machine interface unit can be configured with an HMI interface for the central control console to display the status of each grating, button trigger records, current reset step number, remaining time, and fault information in real time; it supports operators to check whether the automatic mold changing conditions are met and provides interruption reason prompts when a reset is abnormal; the HMI is not used to directly trigger the reset action, but only as a status monitoring and diagnostic tool to ensure that the control logic is executed independently by the hardware buttons and the safety PLC.

[0071] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0072] Please see Figure 2 The diagram shows a flowchart of a stamping line grating safety reset method based on sequential button confirmation in a specific embodiment. The method includes:

[0073] S101. Check whether the automatic mold changing condition corresponding to the grating reset of the stamping line is met; if not, wait until the condition is met; if it is met, proceed to step S102.

[0074] In some embodiments, the controller in the stamping equipment connects to the control modules of the die changing device, conveying mechanism, and press of the stamping line through pre-deployed signal acquisition interfaces. It acquires in real-time the locking signal from the die changing device, the track position signal from the conveying mechanism, and the position signal of the press slide resetting to the top dead center. A physical signal transmission link is established through the hardware interface. Using preset ready state thresholds and mode codes, a comprehensive judgment criterion for automatic die changing conditions is formed. If the conditions are not met, the system maintains a waiting state until all judgment items are satisfied.

[0075] As a specific embodiment, S101 specifically includes the following steps:

[0076] S1011: The controller sends self-test commands to each monitoring area of ​​the grating protection device and collects power supply status and signal transmission integrity data for each area.

[0077] In some embodiments, the controller sends self-test request frames to each of the three groups of grating protection devices set on one side. Upon receiving the request, each group of gratings collects its transmitter power supply voltage and receiver signal reception status, and sends a feedback frame containing the voltage value and signal on / off status back to the controller. The controller presets an effective voltage range and a signal path integrity determination rule. The signal path integrity determination rule can be that three consecutive sampled signals are validly paired. The controller compares the returned data with the preset rule one by one to mark whether the group of gratings meets the hardware self-test conditions.

[0078] S1012: The controller retrieves the current operating mode data stored in the stamping line control system and determines whether it belongs to the mode category that allows grating reset.

[0079] In some embodiments, the controller establishes a communication connection with the main control PLC of the stamping line via an industrial Ethernet, reads the current operating mode code stored in the PLC, and pre-stores a list of condition modes that allow the ADC. The controller compares the read current mode code with the list one by one to determine whether they match.

[0080] S1013: The controller integrates environmental monitoring data from the monitoring unit with real-time occlusion signals from the grating to determine whether there are safety risks from personnel or obstacles within the protected area.

[0081] In some embodiments, the controller receives the personnel detection results of the protected area output by the video analysis server of the monitoring unit, collects the occlusion signals sent in real time by each grating protection device, and matches the personnel detection results with the occlusion signals to generate a safety status indicator for the protected area.

[0082] S102: In response to the operator pressing the first reset button, the inlet grating, the protection grating and the outlet grating corresponding to the first reset button are activated simultaneously, the indicator light of the first reset button is set to a constant-on state, and the first confirmation button is put into a flashing state and the timer is started.

[0083] In some embodiments, a valid operation signal is used as the trigger point, and the reset button and the grating group are precisely associated through address mapping. The grating is activated and the indicator light status is switched by using level signal control. The timing module is started synchronously to limit the operation time point, forming a linkage between operation touch, unit response, status prompt and time constraint.

[0084] As an embodiment of the present invention, S102 specifically includes the following steps:

[0085] S1021: The controller retrieves the address of the grating group corresponding to the first reset button, outputs a high-level drive signal to the power control circuit of the input grating, protection grating and output grating corresponding to that address, starts the infrared beam function of the grating, and triggers the fault self-diagnosis module of the grating.

[0086] In some embodiments, the storage unit can pre-store an address mapping table between each reset button and the corresponding side grating group. When a press signal of the first reset button is received, the controller matches the grating group address corresponding to the button from the table. The controller outputs a 24V high-level signal to the grating power control circuit corresponding to the address, energizing the grating's switching power supply module and driving the transmitters of the inlet, protection, and outlet gratings to start emitting infrared beams. The receivers simultaneously switch to signal receiving mode.

[0087] The built-in fault self-diagnosis module of the grating is activated. Through the built-in voltage detection element, it collects the power-on voltage values ​​of the transmitter and receiver in real time and sends the voltage status signal back to the controller.

[0088] S1022: The controller sends a energizing command to the control relay of the first reset button indicator light, closing the power supply circuit of the indicator light and energizing it.

[0089] In some embodiments, while outputting the grating drive signal, the controller also sends an activation signal to the control relay of the first reset button indicator. After the relay coil is energized, the normally open contact closes, the 24V DC power supply circuit of the indicator light is turned on, and current flows through the indicator's light-emitting element, illuminating the indicator. During this process, the controller collects the current signal of the indicator light circuit in real time. When the current value is within a preset normal range, the controller determines that the indicator light is in a constantly lit state. The controller verifies the actual conduction state of the circuit through current signal feedback to ensure that the indicator light illuminates effectively.

[0090] S1023: The controller retrieves the preset flashing frequency parameters, outputs a pulsed level signal to the first confirmation button indicator light, and simultaneously triggers the operation timing module to start timing by calling the preset time parameters corresponding to the confirmation button.

[0091] In some embodiments, the controller retrieves pre-configured confirmation button flashing frequency parameters from the storage unit and outputs alternating high and low level signals to the first confirmation button indicator light. When the level is high, the indicator light's power supply circuit is turned on and illuminates.

[0092] When the level is low, the circuit is broken and the screen goes out, thus creating a blinking effect.

[0093] The timing module inside the controller is triggered by the level signal, which calls the preset time parameter bound to the confirmation button, and the clock element inside the timing module begins to accumulate time.

[0094] This method uses alternating pulsed level signals to control the on / off frequency of the indicator light, thus achieving a flashing notification.

[0095] S103: In response to the operator pressing the first confirmation button within a preset time range, the indicator light of the first confirmation button is switched to a constant-on state, and the second confirmation button in the next sequence is put into a flashing state and the timer is started.

[0096] In some embodiments, based on the verification results of valid operation signals, the button state is progressively updated, the next operation node is locked through a sequential mapping table, and the operation progression method of the current guidance is constructed based on level signal switching and timing start.

[0097] As an embodiment of the present invention, S103 specifically includes the following steps:

[0098] S1031: The controller receives the pressed signal of the first confirmation button, retrieves the timing module data corresponding to the first confirmation button, and compares whether the signal trigger time is within the preset time range; it starts the level detection submodule to detect the duration of the continuous high level of the signal and filters valid operation signals.

[0099] S1032: The controller stops outputting pulse level signals to the first confirmation button indicator light, switches to a continuous high level signal, closes the power supply circuit of the indicator light, and marks the operation status of the button as completed and stores it in the register.

[0100] In some embodiments, by switching the type of output signal from pulse to continuous high level to control the lighting state of the indicator light, and by using registers to store the operation progress, the process status can be visualized and synchronized.

[0101] S1033: The controller retrieves the next sequential button corresponding to the first confirmation button from the sequence button mapping table, which is the address of the second confirmation button, and outputs a pulse level signal of preset frequency to the indicator light corresponding to the address of the second confirmation button; it starts the timing module corresponding to the button, loads the preset time parameters, and starts timing.

[0102] In some embodiments, the order of operations is determined based on a sequence button mapping table, the indicator light flashes to indicate the operation via a pulse level signal, and the timing module loads preset parameters to limit the time range of the operation.

[0103] The operator moves along the preset route by pressing the button. The flashing status clearly indicates the next position to be operated, and the loading of timing parameters ensures that the operator has enough time to complete the safety inspection and movement of the corresponding area.

[0104] S104: Repeat step S103 to respond to the press of each sequential confirmation button in turn until the press of the last intermediate confirmation button is responded to.

[0105] In some embodiments, an automated loop retrieval logic is constructed based on the association between the stored data in the register and the sequential mapping table. By setting the loop termination condition through identifier comparison, the established signal verification process is reused to achieve continuous advancement of multi-node operations.

[0106] As an embodiment of the present invention, S104 specifically includes the following steps:

[0107] S1041: The controller reads the confirmation button identifier of the completed operation from the register, starts the loop trigger mode, uses the current completion identifier as an index, and retrieves the address of the next confirmation button to be operated from the sequence button mapping table.

[0108] In some embodiments, the register allocates an independent storage bit for each confirmation button, and a storage bit of "1" indicates that the button has completed the operation. After starting the loop trigger mode, the controller first traverses all storage bits set to "1" in the register and extracts the corresponding button identifier.

[0109] In this embodiment, the identifier is used as the retrieval condition to find the unique address code of the next button to be operated from the pre-stored sequence button mapping table. The address code is temporarily stored in the controller's temporary buffer area as the target address for subsequent signal acquisition.

[0110] In this embodiment, the controller sends the address information of the button to be operated to the human-machine interaction unit through the industrial bus, updates the process progress indicator of the interactive interface, and locates the hardware address of the next operation node.

[0111] S1042: The controller continuously collects the signal of the confirmation button to be operated, synchronously calls the timing module data corresponding to the confirmation button to be operated, and repeatedly executes the signal validity and timeliness verification logic of step S1031.

[0112] In some embodiments, when the controller detects that the level changes from low to high, it calls the built-in signal verification subroutine, reads the current cumulative duration of the timing module corresponding to the confirmation button to be operated, and determines whether it is within the preset time range; then it counts the duration of the high-level signal. If the duration reaches 200ms or more, it is determined to be a valid operation signal, triggering the indicator light state switching logic in step S1032.

[0113] If no valid signal is detected, or if a timeout signal is detected, the controller will maintain its current listening state and will not update the address information in the temporary buffer.

[0114] S1043: After the controller completes the operation status flag of a confirmation button each time, it retrieves the preset last intermediate confirmation button identifier and compares it with the currently completed button identifier. If they do not match, it returns to step S1041. If they match, it terminates the loop triggering mode.

[0115] In some embodiments, the controller's storage unit predefines a unique identifier for the last intermediate confirmation button, which is distinguished from the identifiers of other confirmation buttons by using a different encoding prefix. After each confirmation button operation status is completed, the controller extracts the complete identifier of that button and performs a binary comparison with the preset identifier of the last intermediate confirmation button.

[0116] If the comparison results are inconsistent, it means that there are still intermediate buttons that have not completed the operation. The controller clears the old address information in the temporary buffer area and returns to step S1041 to search for the next button to be operated.

[0117] If the comparison results match, the controller immediately sends a termination command to the cyclic trigger mode, and simultaneously writes the current completion status to the storage unit to prevent progress loss due to sudden power outages.

[0118] S105: In response to the last intermediate confirmation button being pressed, the control exit grating enters a disabled state for a predetermined time.

[0119] As an embodiment of the present invention, S105 specifically includes the following steps:

[0120] S1051: The controller reads the operation completion signal of the last intermediate confirmation button, verifies the validity of the signal level and the integrity of the signal transmission link, and retrieves the operation status of all previous intermediate confirmation buttons in the register.

[0121] In some embodiments, after receiving the high-level completion signal from the last intermediate confirmation button, the controller uses a built-in signal integrity detection module to detect the high-level amplitude and the steepness of the signal's rising edge, eliminating false triggering caused by signal attenuation or interference. The controller collects the differential voltage of the signal transmission link to confirm that there are no short circuits or open circuits in the link. After completing the signal verification, the controller traverses the storage bits corresponding to all previous intermediate confirmation buttons in the register, ensuring that all storage bits are in the "1" completed state and that there are no incomplete indicators or abnormal markers.

[0122] S1052: The controller outputs a low-level cutoff signal to the power control circuit of the output grating, disconnects the power supply link of the output grating, and sends an output grating disabled status signal to the human-machine interaction unit.

[0123] In some embodiments, the controller sends a low-level signal to the dedicated power control relay of the output grating. After the relay coil is de-energized, the normally closed contact opens, cutting off the 24V DC power supply circuit between the output grating transmitter and receiver, and the output grating stops emitting infrared beams.

[0124] The controller sends a status code containing the exit light grid disabled to the human-machine interface unit (HMI). The HMI display module of the HMI corresponds to the status indicator light of the exit light grid and simultaneously records the disabled trigger timestamp.

[0125] S1053: The controller starts the disable timing module corresponding to the disable of the exit grating, loads the preset disable time parameters, and collects the power status signal of the exit grating in real time to monitor the disable status.

[0126] In some embodiments, the controller activates an internal independent high-precision real-time timing module, retrieves a preset exit grating disable time parameter from the storage unit, and writes the parameter into the timing module's counter register as the timing upper limit.

[0127] The timing module starts counting down from its internal crystal oscillator and sends the remaining time back to the controller after each count.

[0128] The controller continuously collects the voltage signal of the output grating power control circuit, monitoring in real time whether the circuit is in an open state. If an abnormal voltage rise is detected, the timing module is triggered to pause counting and a warning signal is sent to the alarm unit. In this way, real-time voltage monitoring can immediately detect abnormal connection of the power supply circuit, provide early warning of potential safety risks, and ensure the stability of the disabled state.

[0129] S106: Reactivate the exit grating in response to the operator pressing the exit reset button during the exit grating's disabled state.

[0130] As an embodiment of the present invention, S106 specifically includes the following steps:

[0131] S1061: The controller receives the trigger signal from the output reset button, verifies the duration of the signal's continuous high level to filter valid operations, reads the remaining duration of the disable timing module for the output grating, and confirms that the operation occurred during the disable period; it also acquires the voltage signal of the output grating power supply circuit to verify that it is currently in a disabled state.

[0132] In some embodiments, the controller initiates a signal validity identification process after detecting a level change in the output reset button.

[0133] Specifically, the built-in level detection circuit confirms that the high-level signal amplitude is stable within the industrial standard range of 22-26VDC, and then the duration of the high level is timed.

[0134] When the duration reaches 200ms or more, it is determined to be a real operation signal.

[0135] The controller reads the current count of the disabled timing module. If the remaining time is greater than 0, it confirms that the operation is within the disabled time period.

[0136] The controller collects the voltage value of the power supply circuit of the output grating in real time. If the voltage is lower than 3VDC, it verifies that the output grating is currently in a disabled state. After all conditions are met, it proceeds to S1062.

[0137] S1062: The controller outputs a high-level drive signal to the power control circuit of the output grating, closes the relay contacts of the power supply circuit, and restores power supply to the transmitter and receiver of the output grating; it also sends the output grating activation status code to the human-machine interface unit.

[0138] In some embodiments, after the controller confirms that all trigger conditions are met, it sends a 24V high-level drive signal to the dedicated relay of the output grating power control circuit.

[0139] After the relay coil is energized, the normally open contact closes, reconnecting the 24V DC power supply link between the output grating transmitter and receiver, and the grating then starts the infrared beam transmission and reception process.

[0140] In this embodiment, after the controller sends the "Exit Grating Activation" status code 0x0003 to the human-machine interaction unit, the status indicator light of the corresponding exit grating switches to solid green and records the timestamp of the activation operation and the operator's authorization identifier.

[0141] S1063: The controller initiates the exit grating activation status detection process, receives the working status signal fed back by the grating self-diagnosis module, sends a stop counting command to the disable timing module, and updates the status flag of the exit grating in the register.

[0142] In some embodiments, after outputting the power supply drive signal, the controller initiates closed-loop detection of the activation state. The signal fed back by the fault self-diagnosis module built into the grating confirms that the transmitter and receiver are powered on normally and detects the integrity of the grating's infrared beam alignment.

[0143] If the receiver can stably receive the full-range beam signal, the activation is considered successful.

[0144] The controller sends a stop counting command to the disabled timing module of the exit grating to stop the countdown and clear the current count register.

[0145] The controller sets the storage location corresponding to the activation status of the exit grating in the register to "1" and writes the successful activation result into the storage unit, thus completing the recording of the operation progress.

[0146] S107: Continue to respond to the press operations of each subsequent confirmation button in sequence until the press operation of the final reset button on the main control panel is responded to.

[0147] In some embodiments, after the exit grating is reactivated, the controller retrieves the address of the next subsequent confirmation button corresponding to the exit reset button from the sequence button mapping table, temporarily stores the address in a temporary buffer, stops listening to the signals related to the exit area, and switches to the directional signal acquisition mode of the subsequent confirmation button.

[0148] In this embodiment, the main execution mode of S103 is repeated. The signal input of the button to be operated is monitored, and the amplitude and duration of the signal are verified. After confirming that it is valid, the indicator light of the button is controlled to change from flashing to solid light, and it is marked as "completed" in the register. Then, the next button to be operated is retrieved through the mapping table, and its flashing and timing are started.

[0149] The execution process in this embodiment continues in a loop until the controller detects the signal input from the final reset button on the main control panel. At this point, the signal is validated using the same standard as other confirmation buttons. Once valid, the loop search for subsequent buttons is terminated, and the process proceeds to step S108. This logical consistency reduces program redundancy in the controller and improves operational stability.

[0150] S108: In response to the final reset button being pressed, the grating reset process on one side of the stamping line is completed.

[0151] As an embodiment of the present invention, S108 specifically includes the following steps:

[0152] S1081: The controller receives the trigger signal from the final reset button, verifies the signal level amplitude and duration to confirm the validity of the operation; it traverses the registers to check the operation status of all confirmation buttons and reset buttons on one side, as well as the activation status of the inlet grating, protection grating, and outlet grating.

[0153] In some embodiments, after the controller detects the level transition of the final reset button, it initiates signal validity identification. After identification, a timing unit is started to count the duration of the high level. Only when the duration reaches 200ms or more and there are no level fluctuations during the period is it determined to be a genuine and valid operation by the operator.

[0154] The controller traverses all relevant storage bits in the registers via the internal data bus, checking the operation status of the first reset button, the exit reset button, all intermediate confirmation buttons, and the final reset button to ensure they are all "completed." It also checks the activation status of the inlet grating, the protection grating, and the exit grating to ensure they are all "normally functioning." Only after all checks are passed does the controller proceed to step S1082. This prevents operation from being triggered due to accidental activation of the final reset button, signal interference, or incomplete execution of previous procedures.

[0155] S1082: The controller outputs a stop signal to the warning unit, cuts off the power supply circuit of the strobe light; uniformly switches the working status of all button indicator lights on one side, and also sends a reset process completion status code to the human-machine interaction unit;

[0156] In some embodiments, after the controller confirms that all preconditions are met, it sends a low-level signal to the dedicated control relay of the strobe light. When the relay coil is de-energized, the normally open contact opens, cutting off the 24V DC power supply circuit to the strobe light, and the strobe light stops flashing.

[0157] The controller switches the control signals of all buttons and indicator lights that have completed operations from a continuous high level to a low level, turning off the indicator lights; if there are buttons that need to maintain their status indication, their current signal state is maintained.

[0158] The controller sends the "Single-sided grating reset complete" status code to the human-machine interface unit, and the status indicator of the corresponding single-sided area is switched to "Reset complete".

[0159] S1083: The controller writes the status information of the single-sided grating reset completion to the storage unit and generates a reset process completion report; it sends a process unlock signal to the stamping line control panel to allow the start of subsequent production-related operations.

[0160] In some embodiments, after the controller completes the state switch, it writes the status data of the single-sided grating reset to the storage unit. The data content includes the reset completion timestamp, the operation time record of all buttons, the grating state change log and the operator's permission identifier, ensuring that the data is not lost after the device suddenly loses power or restarts.

[0161] An internal report generation subroutine is initiated to generate a reset process completion report based on stored log data. The controller sends a process unlock signal to the stamping line's central control panel. This signal carries a region identifier code indicating that the reset on one side has been completed. Upon receiving this signal, the central control panel unlocks the relevant production operations on that side, allowing subsequent processes such as mold conveying and press preparation to begin. In this way, the cross-system unlock signal enables seamless integration between the reset process and the production process, improving production efficiency.

[0162] Furthermore, such as Figure 3 As shown, as a refinement and extension of the above-mentioned embodiment of the stamping line grating safety reset method based on sequence button confirmation, the method specifically includes the following:

[0163] The grating protection device in this embodiment is based on a single-sided edge attachment.

It can detect the power-on and signal transmission status of the transmitter and receiver in real time, and the fault signal is uploaded to the controller in real time.

The controller uses a Siemens S7-1500 safety PLC, with built-in verification and control modules adapted to the revised technical solution.

[0171] The specific steps for single-sided grating reset are as follows:

[0172] S101: Check whether the automatic die change (ADC) condition corresponding to the grating reset of the stamping line is met; if not, wait until the condition is met; if it is met, proceed to step S102.

[0180] The time intervals between the confirmation buttons in this embodiment (such as ② and ③, ⑥ and ⑧) are based on the appendix. Figure 3 Adjust the actual length of the corresponding workstation to ensure that operators have sufficient time to complete the area inspection. During the reset process, if an attachment is detected... Figure 3 If unauthorized personnel enter the moving area of ​​the workbench / tooling cart, the current reset process will be immediately terminated, the personnel will be removed, and step S101 will be re-executed. The grating reset process on the other side of the stamping line is the same as this single-side process and its appendix.
