Description

Technical Field

[0001] This invention relates to the field of mold debugging safety technology, specifically to an intelligent error-proof reminder system and method for mold debugging presses. Background Technology

[0002] During the commissioning of stamping dies, operators need to frequently install and disassemble the dies. This process typically requires the upper slide of the press to remain at the bottom dead center position to provide operating space. However, existing press control systems generally suffer from the following defects: 1. Lack of automatic identification capability for "mold change conditions": The system cannot determine whether it is currently in the mold installation / disassembly stage and relies solely on the operator's subjective memory; 2. No pressure plate status detection and interlocking mechanism: If the operator starts the slide return without fully tightening the mold pressure plate or closes the mold without completely removing the mold pressure plate, it is very easy to cause mold overload, breakage or even splashing and injury. 3. Safety reminders are passive and simplistic: Most devices rely solely on posted warning signs or verbal reminders, lacking proactive and mandatory technical intervention methods; 4. The reset mechanism is not closed-loop: Even if there is a simple alarm, it can often be cleared with one click of any button, which cannot ensure that the operator can truly confirm the status of the mold plate.

[0003] In addition, existing mold debugging presses generally only have self-protection functions and basically lack the function of confirming and reminding the mold platen of its status.

[0004] Therefore, there is an urgent need for a low-cost, highly reliable, and intelligent error-proofing solution based on control logic. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of the above-mentioned technologies by providing an intelligent error-proof reminder system and method for mold debugging presses, which ensures operational safety through press status recognition, action prohibition, and alarm reminders.

[0006] To achieve the above objectives, the present invention provides an intelligent error-proof reminder system for mold debugging presses, comprising: 1. An intelligent error-proof reminder system for a mold debugging press, characterized in that it includes: The status recognition module is used to automatically identify the working status of the press. If the upper slide block stays at the bottom dead center position for more than a preset time threshold, the working status is determined to be the mold installation and disassembly status. The action prohibition module prevents the press from operating when the status recognition module detects that the working status is the installation and disassembly of the mold. If the operator starts the return stroke of the upper slide of the press, the press will be prohibited from operating. The alarm reminder module simultaneously activates an audible and visual alarm and a touchscreen alarm when the prohibited action module is triggered, to remind the operator to check the status of the mold pressure plate.

[0007] Preferably, the status recognition module is implemented by modifying the press PLC program, including setting a time delay relay. When the upper slider stays at the lower dead center position for more than a preset time threshold, the time delay relay outputs a contact to control the intermediate relay to determine the working state as the mold installation / disassembly state.

[0008] Preferably, the action prohibition module automatically prohibits the operation of the press by adding an intermediate relay to the inching start condition of the upper slider.

[0009] Preferably, the alarm notification module includes: The alarm condition of the audible and visual alarm is associated with the output contact of the time-delay relay. The touchscreen alarm bar is linked to the status flags in the PLC program and automatically pops up when the installation or disassembly of the mold is detected.

[0010] Preferably, the touch screen alarm prompt bar includes a reset function. The press can only resume normal operation after the operator confirms the status of the pressure plate by using the reset button.

[0011] Preferably, the touchscreen reset operation has an anti-accidental touch design, which is set on a dedicated "real-time alarm" page. It only takes effect when the designated button is clicked on the dedicated "real-time alarm" page, thus avoiding accidental touches on the main interface that could cause safety failure.

[0012] Preferably, the preset time threshold for the status recognition module is 5 minutes, which can be adjusted according to actual needs.

[0013] Preferably, the working states of the press also include: the upper slide block stopping at the top dead center position corresponding to the mold fitting state; the upper slide block completing the full movement corresponding to the mold testing state; the state recognition module only triggers the foolproof reminder when it recognizes the mold installation and disassembly state.

[0014] A method for intelligent error prevention reminders for a mold debugging press, based on the intelligent error prevention reminder system for the mold debugging press, includes the following steps: S1) Real-time detection of whether the upper slide of the press is at the bottom dead center position; S2) If the upper slider is at the bottom dead center, then start timing; S3) Determine whether the timing has reached the preset time threshold; S4) If this condition is met, it is determined that the current state is in the process of installing or disassembling the mold, and the foolproof protection mode is activated. S5) In foolproof protection mode, if a return start command for the upper slider is received, then: a) Prohibit the execution of this return command; b) Trigger the audible and visual alarm to emit a continuous audible and visual alarm; c) A prompt window will pop up on the main screen of the touch screen human-machine interface: "Please confirm the status of the mold platen".

[0015] Preferably, the foolproof protection mode is deactivated and subsequent operations are allowed only after the operator clicks the "Pressure Plate Status Confirmation and Alarm Clearance" button on the touch screen.

[0016] Compared with the prior art, the present invention has the following advantages: 1. Automatically reminds operators to confirm whether the mold pressure plate is in normal working condition to ensure operational safety; 2. No additional sensors are required; the mold changeover conditions can be accurately determined solely by the position of the upper slider and time logic, resulting in high recognition accuracy. 3. Implementing prohibition measures before dangerous operations occur serves as a preventative measure. 4. With triple prompts of sound, light, and screen, the redundancy is high, covering multiple channels of vision and hearing, ensuring that operators cannot ignore them; 5. Forced safety closed loop: the pressure plate status must be confirmed before resetting, eliminating the formalism of "one-click silencing"; 6. Low cost and easy to promote. Only the PLC program and touch screen display need to be modified. It is suitable for most presses with PLC control, with a short modification cycle and low investment. Attached Figure Description

[0017] Figure 1 This is a schematic diagram of an embodiment of the intelligent error-proof reminder system for mold debugging press of the present invention; Figures 2-8 This is a PLC program logic diagram and a touch screen interface diagram according to an embodiment of the present invention.

[0018] The components in the diagram are labeled as follows: 1. Press machine, 2. Upper slide block, 3. Lower dead center position, 4. Touch screen, 5. Audible and visual alarm, 6. Mold. Detailed Implementation

[0019] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. 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.

[0020] Example 1 like Figure 1 As shown, an intelligent error-proof reminder system for a mold debugging press includes: The status recognition module is used to automatically identify the working status of the press 1. If the upper slide 2 stays at the lower dead point position 3 for more than a preset time threshold, the working status is determined to be the mold installation and disassembly status. The action prohibition module prevents the operation of press 1 if the operator starts the return stroke of the upper slider 2 of press 1 when the status recognition module recognizes that the working status is the mold installation and disassembly status. When the prohibited action module is triggered, the alarm reminder module will simultaneously activate the audible and visual alarm 5 and the touch screen 4 to remind the operator to check the status of the mold platen.

[0021] When using this embodiment, the following steps are included: S1) Real-time detection of whether the upper slide block 2 of the press 1 is at the bottom dead center position 3; S2) If the upper slider 2 is at the bottom dead center position 3, then start timing; S3) Determine whether the timing has reached the preset time threshold; S4) If this condition is met, it is determined that the current state is in the process of installing or disassembling the mold, and the foolproof protection mode is activated. S5) In foolproof protection mode, if a return start command for the upper slider 2 is received, then: a) Prohibit the execution of this return command; b) Trigger the audible and visual alarm 5 to issue a continuous audible and visual alarm; c) A prompt window “Please confirm the status of the mold platen” pops up on the main screen of the 4-person touch screen interface.

[0022] The foolproof protection mode is only deactivated and subsequent operations are allowed after the operator clicks the "Plate Pressure Confirmation and Alarm Clearance" button on the touchscreen 4.

[0023] Example 2 like Figure 1 As shown, an intelligent error-proof reminder system for a mold debugging press includes: The status recognition module is used to automatically identify the working status of the press 1. If the upper slider 2 stays at the bottom dead center position 3 for more than a preset time threshold, the working status is determined to be the mold installation and disassembly status. Specifically, the status recognition module is implemented by modifying the PLC program of the press 1, including setting a time delay relay. When the upper slider 2 stays at the bottom dead center position 3 for more than a preset time threshold continuously, the time delay relay outputs a contact to control the intermediate relay to determine the working status as the mold installation and disassembly status. In this embodiment, the preset time threshold of the status recognition module is 5 minutes, which can be adjusted according to actual needs. The action prohibition module prevents the operation of the press 1 when the status recognition module detects that the working status is the installation and disassembly of the mold. Specifically, the action prohibition module prevents the operation of the press 1 by adding the intermediate relay to the inching start condition of the upper slider 2. The alarm reminder module, when the prohibited action module is triggered, simultaneously activates the audible and visual alarm 5 and the touchscreen 4 to remind the operator to check the status of the mold pressure plate. Specifically, the alarm reminder module includes: The audible and visual alarm 5 has its alarm conditions linked to the output contacts of a time-delay relay; The touchscreen 4 alarm prompt bar is associated with the status flags in the PLC program and will automatically pop up when the installation or disassembly of the mold is detected.

[0024] In addition, the touchscreen 4 alarm prompt bar includes a reset function. After the operator confirms the pressure plate status via the reset button, the press machine 1 can resume normal operation. Simultaneously, the touchscreen 4 reset operation has an anti-accidental touch design, located on a dedicated "Real-time Alarm" page. The reset function only takes effect when the designated button is clicked on this dedicated "Real-time Alarm" page, preventing accidental touches on the main interface from causing safety malfunctions.

[0025] When using this embodiment, the following steps are included: S1) Real-time detection of whether the upper slide block 2 of the press 1 is at the bottom dead center position 3; S2) If the upper slider 2 is at the bottom dead center position 3, then start timing; S3) Determine whether the timing has reached the preset time threshold; S4) If this condition is met, it is determined that the current state is in the process of installing or disassembling the mold, and the foolproof protection mode is activated. S5) In foolproof protection mode, if a return start command for the upper slider 2 is received, then: a) Prohibit the execution of this return command; b) Trigger the audible and visual alarm 5 to issue a continuous audible and visual alarm; c) A prompt window “Please confirm the status of the mold platen” pops up on the main screen of the 4-person touch screen interface.

[0026] In addition, in the above embodiments, the working state of the press 1 also includes: the upper slider 2 staying at the upper dead point position corresponding to the mold fitting state; the upper slider 2 completing the full movement corresponding to the mold testing state; the state recognition module only triggers the foolproof reminder when it recognizes the mold installation and disassembly state.

[0027] like Figure 1 As shown, a press 1 includes a PLC, a touch screen 4, an audible and visual alarm 5, and the original machine tool position switch of the press 1. Figure 2As shown, a time-delay relay moldunlockT61 is added to the PLC control program. When the upper slider 2 stays at the bottom dead center position 3 for more than 5 minutes, its contact moldunlockT61.DN controls the intermediate relay stroke.M221.6, which automatically determines that it is in the state of installing or disassembling the mold. When the operator uses the micro-start SB6 or the inching start SB11SB12KA1 to start the press 1, strokeM211.9 is set (the alarm prompt bar is automatically popped up when the mold is detected to be in the state of installation or disassembly).

[0028] like Figure 3 As shown, stroke.M221.6 is added to the condition for starting the movement of the upper slider 2. Once the condition is met, the movement of the upper slider 2 is automatically disabled. Figure 4 As shown, the output contact of the time delay relay, moldunlockT61.DN, is added to the alarm conditions of the audible and visual alarm 5. When the conditions are met, the audible and visual alarm will automatically occur.

[0029] In addition, such as Figure 5 and Figure 6 As shown, an alarm status bar is added to the main page of touchscreen 4, associated with the PLC program strokeM211.9 (which automatically pops up an alarm status bar when the mold is detected to be in the installation or disassembly state). The alarm status bar will automatically appear when the conditions are met. Figure 7 and Figure 8 As shown, a reset alarm button has been added to the real-time alarm screen. After an alarm is triggered, a reset is required before the press machine 1 can operate normally. Furthermore, a check plate reminder is still displayed during the reset process, further ensuring safety.

[0030] This invention relates to an intelligent error-proof reminder system and method for mold debugging presses. It automatically reminds operators to confirm whether the mold platen is in normal working condition, ensuring operational safety. No additional sensors are required; the mold replacement status can be accurately determined solely by the position and time logic of the upper slider 2, resulting in high accuracy. Action prohibition is implemented before dangerous operations occur, playing a preventative role. Through triple prompts of sound, light, and screen, with high redundancy and coverage of multiple visual and auditory channels, it ensures that operators cannot ignore the warnings. A mandatory safety closed loop requires confirmation of the platen's status before resetting, eliminating the formalism of "one-click silencing." It is low-cost and easy to promote, requiring only modifications to the PLC program and the touchscreen 4 display screen. It is applicable to most presses 1 with PLC control, with a short modification cycle and low investment.
