[0019] Furthermore, the terms "first," "second," and "third" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0020] Unless otherwise specified, all terms used herein (including technical and scientific terms) shall have the same meaning as commonly understood by one of ordinary skill in the art to which the various embodiments of this application pertain. Terms (such as those defined in commonly used dictionaries) shall be interpreted as having the same meaning as in their contextual meaning in the relevant technical field and shall not be construed as having an idealized or overly formal meaning, unless clearly defined in the various embodiments of this application.

[0021] It is understood that the method of this application is applied to a stamping production line, which is equipped with visual monitoring equipment and a controller. The visual monitoring equipment can be a camera, webcam, monitoring probe, etc., and is not limited thereto. For ease of explanation, the following embodiments are described using the controller of the stamping production line as the execution subject.

[0022] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0023] Please refer to Figure 1 , Figure 1 This is a flowchart illustrating a first embodiment of the safety protection method for a stamping production line provided in this application. The method is applied to a stamping production line, which is equipped with a visual monitoring device. The method includes: Step S101: In the abnormal handling scenario of the stamping production line, acquire the real-time visual data of the visual monitoring equipment.

[0024] In this embodiment, in the abnormal handling scenario of the stamping production line, professional maintenance personnel need to enter the risk area of ​​the stamping production line for repair. At this time, the visual monitoring equipment installed in the stamping production line will be activated and monitor the risk area of ​​the stamping production line in real time. The controller of the stamping production line can obtain the real-time visual data generated by the visual monitoring equipment in real time.

[0025] It should be noted that the abnormal handling scenario for the stamping production line refers to the scenario where the entire line stops abnormally during the automatic production process of the stamping production line due to equipment, molds, or other reasons. The stamping production line is set up in a closed manner, which restricts all equipment in the stamping production line to a fixed area. The stamping production process is completed by controlling the operation of the equipment through the control panel in the area outside the closed area. Therefore, the risk area of ​​the stamping production line is the area inside the closed area.

[0026] It should be noted that visual monitoring equipment is installed in the stamping production line to monitor the risk areas of the stamping production line. The real-time visual data generated by the visual monitoring equipment can be image data, video data, etc.

[0027] Step S102: Based on the real-time visual data, determine the personnel retention information in the risk area of ​​the stamping production line, and control the start and stop of the stamping production line based on the personnel retention information.

[0028] In this embodiment, the controller of the stamping production line acquires real-time visual data generated by the visual monitoring equipment, analyzes and identifies the real-time visual data to determine personnel lingering information in the risk area of ​​the stamping production line, and controls the start and stop of the stamping production line based on the personnel lingering information. It is understood that in abnormal handling scenarios of the stamping production line, professional maintenance personnel need to enter the risk area of ​​the stamping production line for repairs. At this time, the stamping production line is in a stopped state. The controller of the stamping production line will continuously analyze and identify the real-time visual data generated by the visual monitoring equipment to determine whether the professional maintenance personnel are still lingering in the risk area. If so, the stopped state is maintained; otherwise, the stamping production line can be started.

[0029] In one embodiment, the controller of the stamping production line uses technologies such as spatial perception and distance detection to perform human body detection only on real-time visual data, so as to quickly identify human bodies in risk areas and improve the efficiency of determining personnel lingering information.

[0030] It should be noted that stamping production lines, due to their equipment characteristics—the press stores enormous rotational kinetic energy through a flywheel, which is released to the slide block via a clutch during the stamping process, generating thousands of tons of pressure—this action is instantaneous, high-speed, and cannot be stopped midway (unless under safe braking conditions). Once the mold begins to close, the applied force far exceeds the limits of human endurance, resulting in devastating injuries. Existing stamping production lines rely solely on manual adherence to lockout and tagging procedures and external visual inspections, which can lead to operational defects and blind spots, making them prone to safety accidents and posing extremely high safety hazards.

[0031] In this embodiment, the controller of the stamping production line acquires real-time visual data from the visual monitoring device during abnormal handling scenarios. Based on the real-time visual data, it determines personnel presence information in the risk areas of the stamping production line and controls the start and stop of the stamping production line accordingly. By using visual monitoring equipment to detect whether personnel are present in the risk areas of the stamping production line, it avoids operational defects and blind spots caused by relying solely on manual adherence to lockout and tagging procedures and external visual inspections, thereby reducing safety hazards in abnormal handling scenarios of the stamping production line.

[0032] Please refer to Figure 2 , Figure 2 This is a flowchart illustrating a second embodiment of the safety protection method for a stamping production line provided in this application. The difference between the second embodiment and the first embodiment is that the step of acquiring real-time visual data from the visual monitoring device in an abnormal handling scenario of the stamping production line includes: Step S201: In the abnormal handling scenario of the stamping production line, detect whether there is a shutdown signal triggered by locking and tagging.

[0033] In this embodiment, the controller of the stamping production line detects whether a shutdown signal triggered by locking and tethering exists during abnormal handling scenarios. It should be noted that locking and tethering is a standardized procedure that uses physical locks to cut off the equipment's power supply (such as electricity, hydraulic pressure, or pneumatic pressure) and hangs warning signs to ensure the equipment cannot be accidentally started. Before entering the risk area of ​​the stamping production line, professional maintenance personnel must follow the safety padlock rules, opening the safety door and hanging the safety lock and warning signs. At this time, the power supply to the stamping production line will be cut off, and the controller will trigger the corresponding shutdown signal.

[0034] Step S202: If the shutdown signal exists, it is determined that there are personnel remaining in the risk area of ​​the stamping production line.

[0035] In this embodiment, if the controller of the stamping production line detects that a stop signal has been triggered, it determines that there are personnel remaining in the risk area of ​​the stamping production line. At this time, the controller of the stamping production line keeps the stamping production line in a stopped state.

[0036] Step S203: If the shutdown signal does not exist, then acquire the real-time visual data of the visual monitoring device.

[0037] In this embodiment, if the controller of the stamping production line detects that a stop signal has not been triggered, it acquires real-time visual data from the visual monitoring equipment. It is understood that existing stamping production lines determine whether personnel are lingering in risk areas based on whether locks and tags are worn to trigger a stop signal. However, if professional maintenance personnel forget to lock and tag their vehicles when entering a risk area, and the controller starts the stamping production line, it could cause a major safety accident. Therefore, to ensure safety, when the controller of the stamping production line detects that a stop signal has not been triggered, it further acquires real-time visual data from the visual monitoring equipment, and then further determines whether personnel are lingering in risk areas based on the real-time visual data.

[0038] Understandably, by detecting whether there is a shutdown signal triggered by locking and tagging, and by combining real-time visual data from visual monitoring equipment to determine whether there are personnel lingering in risk areas, dual detection of personnel lingering can be achieved, further improving the accuracy of personnel lingering detection and helping to reduce potential production safety hazards.

[0039] In one embodiment, after the step of acquiring real-time visual data of the visual monitoring device if the shutdown signal does not exist, the method includes: Step S204: Based on the real-time visual data, if it is determined that there are personnel lingering in the risk area of ​​the stamping production line, then the personnel information in the risk area is identified.

[0040] Step S205: Bind the personnel information to the security violations of not locking and tagging, and perform statistics and alarms.

[0041] In this embodiment, if the controller of the stamping production line detects that no stop signal has been triggered, it acquires real-time visual data from the visual monitoring equipment and determines that there are personnel lingering in the risk area of ​​the stamping production line based on the real-time visual data. At this time, the controller identifies the personnel information of the lingering personnel in the risk area; binds the personnel information with the safety violation of not locking and tagging, and performs statistics and alarms.

[0042] Understandably, if the monitoring equipment detects personnel remaining in a risk area even though no shutdown signal has been triggered, it indicates that the maintenance personnel forgot to lock and tag the area upon entering, constituting a serious safety violation. The controller can record such serious safety violations and statistically analyze and issue alarms for non-violations to help maintenance personnel correct their bad habits.

[0043] Please refer to Figure 3 , Figure 3 This is a flowchart illustrating a third embodiment of the safety protection method for a stamping production line provided in this application. The difference between the third embodiment and the first to second embodiments lies in the step of determining personnel lingering information in the risk area of ​​the stamping production line based on the real-time visual data, and controlling the start and stop of the stamping production line based on the personnel lingering information, which includes: Step S301: Based on the real-time visual data, if it is determined that there are no personnel remaining in the risk area of ​​the stamping production line, then control the stamping production line to start.

[0044] Step S302: Based on the real-time visual data, if it is determined that there are personnel remaining in the risk area of ​​the stamping production line, then the stamping production line is controlled to remain in a stopped state.

[0045] In this embodiment, the controller of the stamping production line determines, based on real-time visual data, whether there are no personnel remaining in the risk area of ​​the stamping production line, and whether the stamping production line remains shut down.

[0046] In one embodiment, in an abnormal handling scenario of the stamping production line, after a professional maintenance personnel enters the stamping production line, the controller of the stamping production line determines, based on real-time visual data, that there are personnel remaining in the risk area of ​​the stamping production line, and controls the stamping production line to remain in a stopped state. While the professional maintenance personnel remain in the risk area to perform maintenance, the controller continuously acquires real-time visual data to determine that the professional maintenance personnel are still in the risk area, and continues to control the stamping production line to remain in a stopped state. After the professional maintenance personnel complete the maintenance and leave the risk area, the controller continues to acquire real-time visual data to determine that there are no personnel remaining in the risk area, and then allows the stamping production line to start, that is, to restore the energy supply of the stamping production line. When the operator issues a start command, the stamping production line can be started, or the controller can automatically start the stamping production line.

[0047] In one embodiment, after determining, based on the real-time visual data, that there are personnel lingering in the risk area of ​​the stamping production line, the step includes: Step S303: Count the total number of personnel remaining in the risk area of ​​the stamping production line.

[0048] Step S304: The visual monitoring device identifies the entry and exit of personnel into the risk area, and the total number of stranded personnel is adjusted.

[0049] Step S305: Until the total number of stranded personnel is determined to be zero, control the stamping production line to start.

[0050] In this embodiment, the controller of the stamping production line counts the total number of personnel remaining in the risk area of ​​the stamping production line based on real-time visual data. The total number of personnel remaining is adjusted based on the visual monitoring equipment that identifies personnel entering and leaving the risk area. The stamping production line is then started once the total number of personnel remaining is determined to be zero.

[0051] In one embodiment, after a professional maintenance worker enters the risk area, the controller of the stamping production line counts the total number of personnel remaining in the risk area based on real-time visual data. If, based on real-time visual data collected by the visual monitoring equipment, a professional maintenance worker leaves the risk area and no other professional maintenance worker enters, the total number of remaining personnel is decremented by one. If, based on real-time visual data collected by the visual monitoring equipment, a professional maintenance worker enters the risk area and no other professional maintenance worker leaves, the total number of remaining personnel is incremented by one. The total number of remaining personnel is continuously adjusted until it is determined to be zero, at which point the stamping production line is started.

[0052] In one embodiment, when multiple professional maintenance personnel handle malfunctions on the stamping production line, relying solely on counting the total number of personnel remaining in the risk area may lead to statistical errors, as these personnel may frequently enter and exit the risk area. Therefore, the visual monitoring equipment features facial recognition capabilities. It can identify each professional maintenance personnel entering the risk area by recognizing their face, and then track their movements based on this information. This allows it to determine which personnel are within and outside the risk area. Only after confirming that every professional maintenance personnel is outside the risk area is the stamping production line allowed to start.

[0053] The controller of the stamping production line in this embodiment continuously counts and updates the total number of personnel remaining in the risk area based on real-time visual data until the total number of personnel remaining is determined to be zero, at which point the stamping production line is started. By continuously counting and updating the total number of personnel remaining in the risk area in real time, the accuracy of personnel presence detection is further improved, which helps to reduce potential production safety hazards.

[0054] Please refer to Figure 4 , Figure 4 This is a flowchart illustrating the fourth embodiment of the safety protection method for a stamping production line provided in this application. The difference between the fourth embodiment and the first to third embodiments is that the visual monitoring device is electrically connected to the safety module of the stamping production line, and the safety module is electrically connected to the logic controller of the stamping production line. The method further includes: Step S401: Based on the real-time visual data from the visual monitoring device, the safety module determines the personnel lingering information in the risk area of ​​the stamping production line.

[0055] Step S402: The personnel stay information is sent to the logic controller through the safety module, and the logic controller controls the start and stop of the stamping production line according to the personnel stay information.

[0056] In this embodiment, reference Figure 5 , Figure 5 This diagram illustrates the electrical connections between the visual monitoring equipment, safety module, and logic controller provided in this application. The visual monitoring equipment (visual camera) is electrically connected to the safety module, and the safety module is electrically connected to the logic controller (PLC). Real-time visual data collected by the visual monitoring equipment is fed back to the safety module in real time. Based on the real-time visual data, the safety module determines personnel presence information in the risk areas of the stamping production line and sends this information to the logic controller. The logic controller then controls the start and stop of the stamping production line based on the personnel presence information.

[0057] In this embodiment, the visual monitoring device is electrically connected to the safety module, and the safety module is electrically connected to the logic controller. This allows the visual monitoring device to be connected to the logic controller of the stamping production line via a hard connection, which improves the stability of signal transmission, helps to improve the accuracy of personnel lingering detection, and helps to reduce production safety hazards.

[0058] Please refer to Figure 6 , Figure 6 This is a flowchart illustrating the fifth embodiment of the safety protection method for a stamping production line provided in this application. The difference between the fifth embodiment and the first to fourth embodiments is that the visual monitoring equipment is respectively installed in the line-start loading area, the press equipment area, the die-changing areas on both sides of the stamping line, the automation equipment area, and the line-end unloading area of ​​the stamping production line. The method further includes: Step S501: Obtain the real-time visual data of the visual monitoring equipment set in each area of ​​the stamping production line through the safety module, and count the personnel lingering information in each area.

[0059] Step S502: Based on the personnel retention information of each area, determine the personnel retention information of the risk areas of the stamping production line.

[0060] In this embodiment, visual monitoring devices are respectively installed in the feeding area at the beginning of the stamping production line, the press equipment area, the die-changing areas on both sides of the stamping line, the automated equipment area, and the unloading area at the end of the line. A safety module acquires real-time visual data from the visual monitoring devices in each area of ​​the stamping production line and collects personnel lingering information for each area. Based on the personnel lingering information for each area, the personnel lingering information for the risk areas of the stamping production line is determined.

[0061] In one embodiment, reference Figure 7 , Figure 7 This is a schematic diagram illustrating the visual coverage of the visual monitoring equipment for the stamping production line provided in this application. Visual monitoring equipment is installed at both safety gate entrances in the loading area at the beginning of the line. In the press equipment area, the presses, with a tonnage of up to 2500 tons, are a key protection area requiring comprehensive protection without blind spots. Two visual monitoring devices are installed diagonally on each press column to monitor the internal status of the press in real time. In the die-changing areas on both sides of the stamping line, visual monitoring equipment is installed on both sides to prevent personnel from failing to evacuate in time during die-changing. The workbench travel area has full visual protection coverage to ensure safety during die-changing. The automated equipment area generally uses robots, single-arm or double-arm structures, which experience significant impact during high-speed operation and are also a key protection area. Visual monitoring equipment provides comprehensive coverage to monitor safety anomalies during automated operation in real time. The unloading area at the end of the line mainly includes robot unloading and belt conveyor transmission structures. Visual monitoring equipment primarily covers the robot's movement range.

[0062] In this embodiment, visual monitoring equipment is installed in the feeding area at the beginning of the stamping production line, the press equipment area, the die-changing areas on both sides of the stamping line, the automated equipment area, and the unloading area at the end of the line. Based on real-time visual data from each area, personnel lingering information in the risk areas of the stamping production line is determined. This achieves comprehensive monitoring of the stamping production line without blind spots, avoids the occurrence of monitoring blind spots, improves the accuracy of monitoring and personnel lingering information statistics, and helps reduce production safety hazards.
