Technical Field

[0001] This application belongs to the field of die-casting equipment technology, and specifically relates to a method and device for detecting peripheral signals of a die-casting machine. Background Technology

[0002] Currently, in a fully automated production line consisting of a die-casting machine and peripheral equipment, the die-casting machine and peripheral equipment typically need to be linked and controlled to achieve production. Peripheral equipment usually includes pouring equipment, part removal equipment, and spraying equipment. In actual production applications, because the die-casting machine and peripheral equipment are manufactured by different companies, compatibility issues exist, requiring signal interaction testing between the die-casting machine and peripheral equipment. Since it's not possible to test whether the signal interaction between the die-casting machine and peripheral equipment conforms to the company's peripheral signal interaction specifications in the workshop, it is usually only possible to test whether the signal interaction between the die-casting machine and peripheral equipment is normal after assembly at the customer's factory. If the inability to properly link and control the die-casting machine and peripheral equipment is discovered at the customer's factory, the time available for technical personnel to resolve the problem is very short, requiring a high level of skill and experience. This is especially true for die-casting machines exported overseas, where there are currently no solutions for remote monitoring or modifying the die-casting machine program, making it impossible to resolve problems promptly. Summary of the Invention

[0003] This application addresses the compatibility issues mentioned above in practical production applications, where die-casting machines and peripheral equipment are manufactured by different companies, necessitating signal interaction testing between the die-casting machine and peripheral equipment. The proposed method and device for detecting peripheral signals of a die-casting machine are as follows: Firstly, this application provides a method for detecting peripheral signals of a die-casting machine, including: Identify the simulated operation object in the simulated operation command; If the simulated operation object is a simulated peripheral device, then the die-casting machine performs signal simulation processing of the peripheral device based on the preset first simulated operation command; If the simulated operation object is a simulated die-casting machine, then the peripheral equipment is processed to simulate the signal of the die-casting machine based on the preset second simulated operation command.

[0004] In one alternative embodiment of the first aspect, signal simulation processing of peripheral equipment is performed on the die-casting machine based on a preset first simulation operation command, including: When the first allow injection signal sent by the die casting machine is detected, a start injection signal is sent to the die casting machine, and a first allow injection signal is sent to the die casting machine at a preset injection time interval so that the die casting machine can perform the injection operation. When the first permission signal for part removal sent by the die casting machine is detected, a first part removal safety signal to indicate an error is sent to the die casting machine so that the ejector pin of the die casting machine performs an ejection operation; When the ejector pin of the die-casting machine is detected to be in the preset ejection position, the first part removal safety signal used to indicate an error is updated to the first part removal safety signal used to indicate a correct part removal according to the preset part removal time interval, and the first part removal safety signal used to indicate a correct part removal is sent to the die-casting machine.

The first displacement information is calculated based on the preset ejection position and the first position information; The first displacement information is used to calculate the error, and the allowable displacement range is obtained. The second displacement information is calculated based on the second position information and the first position information; When the second displacement information is within the allowable displacement range, the ejector pin of the die-casting machine is determined to be in the preset ejection position; When the second displacement information is not within the allowable displacement range, it is determined that the ejector pin of the die-casting machine is not in the preset ejection position.

[0007] In another alternative to the first aspect, signal simulation processing of the die-casting machine is performed on peripheral equipment based on a preset second simulated operation command, including: Send a second permission signal for soup injection to the peripheral equipment so that the peripheral equipment can perform the soup injection operation; When the second allow injection signal sent by the peripheral device is detected, a start injection signal is sent to the peripheral device, and a second allow pick-up signal is sent to the peripheral device at a preset injection time interval, so that the peripheral device can start to perform the pick-up operation. When a second safety signal for retrieving an item is detected from a peripheral device to indicate an error, a complete ejection signal is sent to the peripheral device at a preset ejection time interval so that the peripheral device can complete the item retrieval operation. When the peripheral device detects that the secondary safety signal used to indicate an error has been updated to a secondary safety signal used to indicate a correct item, the peripheral device completes the item retrieval operation.

[0008] In another alternative to the first aspect, after the peripheral device completes the pickup operation when it is detected that the peripheral device has updated the second pickup safety signal used to indicate an error to a second pickup safety signal used to indicate a correct operation, the method further includes: After sequentially identifying the second spray safety signal sent by the peripheral equipment to indicate an error and the second spray safety signal to indicate a correct operation, a second loop signal is sent to the peripheral equipment to enable the peripheral equipment to perform signal simulation processing of the die-casting machine.

[0009] In another alternative to the first aspect, before performing signal simulation processing of the die-casting machine on the peripheral equipment based on a preset second simulation operation command, the method further includes: Send a soup-injection operation signal to the soup-injection device in the peripheral equipment so that the soup-injection device can perform the soup-injection operation and determine the working status of the soup-injection device; Acquire action data of the soup injection device performing the soup injection operation; Based on motion data and a trained classification model, the working status of the soup-injection device is obtained; the classification model is trained from multiple standard motion data and the working status corresponding to the multiple standard motion data. Based on the preset second simulated operation command, the peripheral equipment is subjected to signal simulation processing of the die-casting machine, which also includes: When the injection equipment is in normal working condition, it performs signal simulation processing on the surrounding equipment based on the preset second simulation operation command.

[0010] Secondly, this application provides a detection device for peripheral signals of a die-casting machine, comprising: The instruction recognition module is used to identify the simulated operation object in the simulated operation instruction; The first test module is used to perform signal simulation processing of the die-casting machine based on a preset first simulation operation command if the simulated operation object is a simulated peripheral device.

[0013] Beneficial effects: In this application, when detecting peripheral signals of a die-casting machine, the simulated operation object in the simulated operation command can be identified first. If the simulated operation object is a simulated peripheral device, the die-casting machine performs signal simulation processing of the peripheral device based on a preset first simulated operation command. If the simulated operation object is a simulated die-casting machine, the peripheral device performs signal simulation processing of the die-casting machine based on a preset second simulated operation command. This involves simulating peripheral devices performing signal simulation processing on the die-casting machine and simulating the die-casting machine performing signal simulation processing of the peripheral device. When simulating peripheral devices, the die-casting machine completes signal interaction testing by interacting with the simulated peripheral devices; when simulating the die-casting machine, the peripheral devices complete signal interaction testing by interacting with the simulated die-casting machine. This effectively avoids compatibility issues and the need for signal interaction testing between the die-casting machine and peripheral devices, which are manufactured by different companies, in actual production applications.

Furthermore, features described with respect to some examples may be combined into other examples.

[0019] Please see Figure 1 , Figure 1 The diagram shows a flowchart of a method for detecting peripheral signals of a die-casting machine according to an embodiment of this application.

[0020] like Figure 1 As shown, the method for detecting signals around the die-casting machine may include at least the following steps: Step 102: Identify the simulated operation object in the simulated operation instruction.

[0021] The method for detecting peripheral signals of the die-casting machine in this embodiment can be applied, but is not limited to, to a control terminal capable of signal interaction. The control terminal, for example, but not limited to, an electronic device integrating a Programmable Logic Controller (PLC) and a display device, can receive input signals from the die-casting machine or peripheral devices, and then output signals through preset control logic to simulate signal interaction between the peripheral devices and the die-casting machine, and vice versa. The display device can be used to output and display the real-time status and parameters of the PLC during signal interaction, and can also directly control the PLC through buttons, switches, or touchscreens on the display device.

[0022] Specifically, the PLC in the control terminal receives the simulation operation instructions sent by the display device, and identifies the simulation operation object by recognizing the simulation operation instructions. The simulation operation object may include, but is not limited to, simulation peripheral equipment and simulation die-casting machine.

[0023] It should be noted that the simulated peripheral equipment in the embodiments of this application may include, but is not limited to, simulated soup-injecting equipment, simulated item retrieval equipment, and simulated spraying equipment; the peripheral equipment may include, but is not limited to, soup-injecting equipment, item retrieval equipment, and spraying equipment.

[0024] Step 104: If the simulated operation object is a simulated peripheral device, then the die-casting machine is subjected to signal simulation processing of the peripheral device based on the preset first simulated operation command.

[0025] Specifically, when the simulated operation object in the simulated operation command is identified as a simulated peripheral device, the die casting machine performs signal simulation processing of the peripheral device. At this time, the die casting machine can first perform the mold closing operation and send the first allow injection signal to the simulated injection device. After receiving the first allow injection signal, the simulated injection device determines that the die casting machine has completed the mold closing operation, sends the start injection signal to the die casting machine, and sends the first allow injection signal to the die casting machine according to the preset injection time interval, so that the die casting machine performs the injection operation.

[0026] Next, after the die-casting machine completes the injection operation, it sends the first permission to pick up the part to the simulated part-picking device. After receiving the first permission to pick up the part, the simulated part-picking device determines that the die-casting machine has completed the injection operation, sets the first part-picking safety signal to False, and sends the first part-picking safety signal to the die-casting machine so that the ejector pin of the die-casting machine can perform the ejection operation.

[0027] Next, when the simulated part-removal device detects that the ejector pin of the die-casting machine has completed the ejection operation, it sets the first part-removal safety signal to True according to the preset part-removal time interval and sends the first part-removal safety signal to the die-casting machine.

[0028] Next, the simulated spraying device sets the first spray safety signal to False and sends the first spray safety signal to the die-casting machine, so that the die-casting machine is in a waiting spraying state; then, according to the preset spraying time interval, the first spray safety signal is set to True and sent to the die-casting machine, so that the die-casting machine ends the waiting spraying state; then, the simulated peripheral equipment sends the first cycle signal to the die-casting machine, so that the die-casting machine performs signal simulation processing of the peripheral equipment.

[0029] It should be noted that True and False mentioned in the embodiments of this application are both Boolean variables, used to characterize the pick-up safety signal and spray safety signal in different states.

[0030] As an optional embodiment of this application, signal simulation processing of peripheral equipment of the die-casting machine is performed based on a preset first simulation operation command, including: When the first allow injection signal sent by the die casting machine is detected, a start injection signal is sent to the die casting machine, and a first allow injection signal is sent to the die casting machine at a preset injection time interval so that the die casting machine can perform the injection operation. When the first permission signal for part removal sent by the die casting machine is detected, a first part removal safety signal to indicate an error is sent to the die casting machine so that the ejector pin of the die casting machine performs an ejection operation; When the ejector pin of the die-casting machine is detected to be in the preset ejection position, the first part removal safety signal used to indicate an error is updated to the first part removal safety signal used to indicate a correct part removal according to the preset part removal time interval, and the first part removal safety signal used to indicate a correct part removal is sent to the die-casting machine.

[0031] Specifically, when the die-casting machine performs signal simulation processing of peripheral equipment based on the preset first simulated operation command, the die-casting machine first performs the mold closing operation and sends the first allow injection signal to the simulated injection device; after receiving the first allow injection signal, the simulated injection device determines that the die-casting machine has completed the mold closing operation, sends the start injection signal to the die-casting machine, and sends the first allow injection signal to the die-casting machine according to the preset injection time interval, so that the die-casting machine sequentially performs the injection operation, the mold opening operation, and the safety door opening operation.

[0032] Next, the die-casting machine sequentially performs the injection operation, mold opening operation, and safety door opening operation, sending the first permission signal for part removal to the simulated part removal device. The preset injection time interval is the time taken for the injection device in the peripheral equipment to perform the injection operation.

[0033] Next, the simulated part-removal device sets the first part-removal safety signal to False and sends the first part-removal safety signal, which indicates False, to the die-casting machine so that the die-casting machine's ejector pin performs the ejection operation.

[0034] Next, when the simulated part-retrieving device detects that the die-casting machine's ejector pin has completed its ejection operation, it updates the first part-retrieving safety signal (indicating False) to a first part-retrieving safety signal (indicating True) according to a preset part-retrieving time interval. The first part-retrieving safety signal indicating True is then sent to the die-casting machine, causing the die-casting machine to perform a safety door closing operation. The preset part-retrieving time interval is the time taken for the part-retrieving device in the peripheral equipment to perform the part-retrieving operation.

[0035] Additionally, when the simulated peripheral equipment detects the ejection completion signal from the die-casting machine, it determines that the die-casting machine's ejector pin has completed the ejection operation. Following a preset part-removal time interval, the first part-removal safety signal indicating False is updated to a first part-removal safety signal indicating True, and this signal is sent to the die-casting machine. The die-casting machine then performs a safety door closing operation. The preset part-removal time interval is the time taken for the part-removal device in the peripheral equipment to perform the part-removal operation.

[0036] As another optional embodiment of this application, after sending the first safe pick-up signal, which indicates that the part is correctly picked up, to the die-casting machine, the method further includes: The first spray safety signal used to characterize an error is sent to the die-casting machine, and the first spray safety signal used to characterize an error is updated to a first spray safety signal used to characterize a correct error according to a preset spray time interval, and the first spray safety signal used to characterize a correct error is sent to the die-casting machine. Send the first cycle signal to the die-casting machine so that the die-casting machine can perform signal simulation processing of peripheral equipment.

[0037] Specifically, after sending the first safe pick-up signal indicating correctness to the die-casting machine, the simulated peripheral equipment sets the first spray safety signal to False and sends the first spray safety signal indicating False to the die-casting machine, putting the die-casting machine into a waiting spray state. Then, according to a preset spray time interval, the first spray safety signal indicating False is updated to a first spray safety signal indicating True, and the first spray safety signal indicating True is sent to the die-casting machine, causing the die-casting machine to end its waiting spray state. The preset spray time is the time taken for the spraying equipment in the peripheral equipment to perform the spraying operation.

[0038] Next, the simulated peripheral equipment sends the first loop signal to the die-casting machine so that the die-casting machine can perform signal simulation processing of the peripheral equipment.

[0039] As another optional embodiment of this application, after sending a first safety signal for identifying an error to the die-casting machine to cause the die-casting machine's ejector pin to perform an ejection operation, before detecting that the die-casting machine's ejector pin is in a preset ejection position, the method further includes: The position information sent by the ejector pin position encoder of the die casting machine is obtained; wherein, the position information includes the first position information of the ejector pin of the die casting machine before the ejection operation is performed and the second position information of the ejector pin of the die casting machine after the ejection operation is performed. The first displacement information is calculated based on the preset ejection position and the first position information; The first displacement information is used to calculate the error, and the allowable displacement range is obtained. The second displacement information is calculated based on the second position information and the first position information; When the second displacement information is within the allowable displacement range, the ejector pin of the die-casting machine is determined to be in the preset ejection position; When the second displacement information is not within the allowable displacement range, it is determined that the ejector pin of the die-casting machine is not in the preset ejection position.

[0040] Specifically, after sending a first safety signal to the die-casting machine to indicate an error, causing the die-casting machine's ejector pin to perform an ejection operation, and before detecting that the die-casting machine's ejector pin is in a preset ejection position, the simulated peripheral equipment acquires the position information sent by the die-casting machine's ejector pin position encoder. This position information includes first position information before the die-casting machine's ejector pin performs the ejection operation and second position information after the die-casting machine's ejector pin performs the ejection operation.

[0041] Next, the first displacement information can be obtained by subtracting the first position information from the preset position information. The maximum allowable displacement range can be obtained by adding the allowable error value to the first displacement information, and the minimum allowable displacement range can be obtained by subtracting the allowable error value from the first displacement information.

[0042] Next, the second displacement information can be obtained by subtracting the first position information from the second position information. When the second displacement information is within the allowable displacement range, it is determined that the ejector pin of the die-casting machine is in the preset ejection position; when the second displacement information is not within the allowable displacement range, it is determined that the ejector pin of the die-casting machine is not in the preset ejection position.

[0043] Step 106: If the simulated operation object is a simulated die-casting machine, then the peripheral equipment is processed to simulate the signal of the die-casting machine based on the preset second simulated operation command.

[0044] Specifically, when the simulated operation object in the simulated operation instruction is identified as a simulated die-casting machine, the peripheral equipment is processed to simulate the signal of the die-casting machine. At this time, the simulated die-casting machine can send a second allow injection signal to the injection equipment so that the injection equipment can perform the injection operation.

[0045] Next, after the injection equipment completes the injection operation, it sends a second permission injection signal to the simulated die casting machine. After receiving the second permission injection signal, the simulated die casting machine determines that the injection equipment has completed the injection operation, sends a start injection signal to the peripheral equipment, and sends a second permission to pick up parts to the picking equipment of the peripheral equipment according to the preset injection time interval, so that the picking equipment can perform the picking operation.

[0046] Next, the part-retrieving device sets the second part-retrieving safety signal to False and sends the second part-retrieving safety signal to the simulated die-casting machine. After receiving the second part-retrieving safety signal, the simulated die-casting machine sends an ejection completion signal to the part-retrieving device according to the preset ejection time interval, so that the part-retrieving device can perform the part-retrieving operation.

[0047] Next, after the part-retrieving device completes the part-retrieving operation, it sets the second part-retrieving safety signal to True and sends the second part-retrieving safety signal to the simulated die-casting machine; after receiving the second part-retrieving safety signal used to characterize True, the simulated die-casting machine determines that the part-retrieving device has completed the part-retrieving operation.

[0048] The spraying device sets the second spray safety signal to False and sends it to the simulated die-casting machine to put the simulated die-casting machine into a waiting spray state. The spraying device performs the spraying operation. After the spraying operation is completed, the second spray safety signal is set to True and sent to the die-casting machine to end the waiting spray state of the simulated die-casting machine. Then, the simulated die-casting machine sends a second cycle signal to the peripheral equipment to enable the peripheral equipment to perform signal simulation processing of the die-casting machine.

[0049] As another optional embodiment of this application, signal simulation processing of the die-casting machine is performed on the peripheral equipment based on a preset second simulation operation command, including: Send a second permission signal for soup injection to the peripheral equipment so that the peripheral equipment can perform the soup injection operation; When the second allow injection signal sent by the peripheral device is detected, a start injection signal is sent to the peripheral device, and a second allow pick-up signal is sent to the peripheral device at a preset injection time interval, so that the peripheral device can start to perform the pick-up operation. When a second safety signal for retrieving an item is detected from a peripheral device to indicate an error, a complete ejection signal is sent to the peripheral device at a preset ejection time interval so that the peripheral device can complete the item retrieval operation. When the peripheral device detects that the secondary safety signal used to indicate an error has been updated to a secondary safety signal used to indicate a correct item, the peripheral device completes the item retrieval operation.

[0050] Specifically, when the peripheral equipment is subjected to signal simulation processing of the die-casting machine based on the preset second simulation operation command, the simulated die-casting machine sends a second allow injection signal to the injection device in the peripheral equipment so that the injection device can perform the injection operation.

[0051] Next, after the injection equipment completes the injection operation, it sends a second permission injection signal to the simulated die-casting machine. Upon receiving the second permission injection signal, the simulated die-casting machine confirms that the injection equipment has completed the injection operation, sends a start injection signal to the peripheral equipment, and sends a second permission to retrieve parts to the retrieval equipment of the peripheral equipment according to a preset injection time interval, so that the retrieval equipment can perform the retrieval operation. The preset injection time includes the time for the die-casting machine to perform the injection operation, the time for the die-casting machine to perform the mold opening operation, and the time for the die-casting machine to perform the safety door opening operation.

[0052] Next, the part-retrieving device sets the second part-retrieving safety signal to False and sends the part-retrieving safety signal indicating False to the simulated die-casting machine. After receiving the second part-retrieving safety signal, the simulated die-casting machine sends an ejection completion signal to the part-retrieving device according to the preset ejection time interval, so that the part-retrieving device can perform the part-retrieving operation.

[0053] Next, after the part-retrieving device completes the part-retrieving operation, it updates the second part-retrieving safety signal, which indicates False, to a second part-retrieving safety signal, which indicates True, and sends the second part-retrieving safety signal indicating True to the simulated die-casting machine. The preset ejection time interval is the time it takes for the die-casting machine to perform the ejection operation.

[0054] As another optional embodiment of this application, after the peripheral device completes the item retrieval operation, when it is detected that the peripheral device updates the second item retrieval safety signal used to indicate an error to the second item retrieval safety signal used to indicate a correct operation, the method further includes: After sequentially identifying the second spray safety signal sent by the peripheral equipment to indicate an error and the second spray safety signal to indicate a correct operation, a second loop signal is sent to the peripheral equipment to enable the peripheral equipment to perform signal simulation processing of the die-casting machine.

[0055] Specifically, when it is detected that the peripheral device updates the second part-retrieving safety signal used to indicate an error to the second part-retrieving safety signal used to indicate a correct operation, after the peripheral device completes the part-retrieving operation, the spraying device in the peripheral device sets the second spraying safety signal to False and sends the second spraying safety signal used to indicate False to the simulated die-casting machine, so that the simulated die-casting machine is in a waiting spraying state. The spraying device performs the spraying operation, and after the spraying operation is completed, it updates the second spraying safety signal used to indicate False to the second spraying safety signal used to indicate True, and sends the second spraying safety signal used to indicate True to the simulated die-casting machine, so that the simulated die-casting machine ends the waiting spraying state.

[0056] Next, the simulated die-casting machine sends cyclic signals to peripheral equipment so that the peripheral equipment can perform signal simulation processing of the die-casting machine.

[0057] As another optional embodiment of this application, before performing signal simulation processing of the peripheral equipment based on the preset second simulation operation command, the method further includes: Send a soup-injection operation signal to the soup-injection device in the peripheral equipment so that the soup-injection device can perform the soup-injection operation and determine the working status of the soup-injection device; Acquire action data of the soup injection device performing the soup injection operation; Based on motion data and a trained classification model, the working status of the soup-injection device is obtained; the classification model is trained from multiple standard motion data and the working status corresponding to the multiple standard motion data. Based on the preset second simulated operation command, the peripheral equipment is subjected to signal simulation processing of the die-casting machine, which also includes: When the injection equipment is in normal working condition, it performs signal simulation processing on the surrounding equipment based on the preset second simulation operation command.

[0058] Specifically, before performing signal simulation processing of the die-casting machine on the peripheral equipment based on the preset second simulation operation command, the control terminal can send the injection operation signal to the injection equipment in the peripheral equipment so that the injection equipment can perform the injection operation and determine the working status of the injection equipment.

[0059] Next, the control terminal acquires the motion data of the soup-pouring device performing the soup-pouring operation, and inputs the motion data into a trained classification model to obtain the working status of the soup-pouring device. The classification model is trained using multiple standard motion data sets and the corresponding working statuses of these standard motion data sets.

[0060] Based on the preset second simulated operation command, the peripheral equipment is subjected to signal simulation processing of the die-casting machine, which also includes: When the injection equipment is in normal working condition, it performs signal simulation processing on the surrounding equipment based on the preset second simulation operation command.

[0061] Please see Figure 2 , Figure 2 This illustration shows a schematic diagram of a signal simulation processing procedure for peripheral equipment of a die-casting machine, provided by an embodiment of this application.

[0062] Specifically, when the simulated operation object in the simulated operation command is identified as a simulated peripheral device, the die casting machine performs signal simulation processing of the peripheral device. At this time, the die casting machine can first perform the mold closing operation and send the allow injection signal to the simulated injection device. After receiving the allow injection signal, the simulated injection device determines that the die casting machine has completed the mold closing operation, sends the start injection signal to the die casting machine, and sends the end injection signal and allow injection signal to the die casting machine in sequence according to the preset injection time interval, so that the die casting machine can sequentially perform the injection operation, mold opening operation, and safety door opening operation.

[0063] Next, after the die-casting machine completes the injection operation, mold opening operation, and safety door opening operation in sequence, it sends a permission to pick up the part signal to the simulated peripheral equipment. After receiving the permission to pick up the part signal, the simulated picking equipment confirms that the die-casting machine has completed the injection operation, sets the picking safety signal to False, and sends the picking safety signal and the permission to eject signal to the die-casting machine so that the ejector pin of the die-casting machine can perform the ejection operation.

[0064] Next, when the simulated part-removal device detects that the die-casting machine's ejector pin has performed an ejection operation, it sets the part-removal safety signal to True according to the preset part-removal time interval and sends the part-removal safety signal to the die-casting machine so that the die-casting machine can perform a safety door closing operation.

[0065] Next, the simulated peripheral equipment sets the spray safety signal to False and sends the spray safety signal to the die-casting machine, so that the die-casting machine is in a waiting spray state; then, according to the preset spray time interval, the spray safety signal is set to True and sent to the die-casting machine, so that the die-casting machine ends the waiting spray state; then, the simulated peripheral equipment sends a loop signal to the die-casting machine, so that the die-casting machine performs signal simulation processing of the peripheral equipment.

[0066] Please see Figure 3 , Figure 3 This illustration shows a schematic diagram of a signal simulation processing procedure for peripheral equipment in a die-casting machine, provided by an embodiment of this application.
