[0052] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more features. In the description of this application, "multiple" means two or more, and "at least one" can mean one, two, or more, unless otherwise explicitly specified.
[0054] During the cutting process, unstable wire tension control can easily lead to decreased cutting capacity or wire breakage, thus affecting the cutting quality. Commonly used wire tension control methods rely too heavily on manual and mechanical adjustments, which are complex to operate and prone to errors or omissions, and also suffer from significant lag.
[0055] In view of this, embodiments of this application provide a wire mesh tension control method, apparatus, device and system, which can directly and precisely control the wire mesh tension without human intervention through an advanced feedback mechanism algorithm, so as to ensure cutting quality and equipment efficiency and stability, reduce the human influence of operators, and thus solve at least some of the above-mentioned technical problems.
[0056] Please see Figure 1 , Figure 1This is a schematic diagram of the wire mesh tension control system according to an embodiment of this application. The wire mesh tension control system of this embodiment includes a sensor 10, a database 20, and a wire mesh tension control device 30. The sensor 10 is installed on the wire cutting machine 40 and is used to collect real-time equipment data from the wire cutting machine 40, such as the tension of the left and right wire rows, the feed speed of the wire cutting machine, and data from the grounding button. The database 20 is used to store standard tension data. The database 20 may include ClickHouse, MySQL, Redis, etc. ClickHouse is an open-source columnar database management system known for its high performance and real-time query capabilities, suitable for handling large-scale data analysis tasks. Because this system collects data from the wire cutting machine in real time, this high-performance columnar query database is required. MySQL is a widely used open-source relational database management system, known for its reliability, ease of use, and wide applicability. This system uses it for storing system management data. Redis is an open-source in-memory data structure store used as a database, cache, and message broker. This system stores data that is not frequently modified but is large in volume and accessed from multiple locations in Redis. The wire mesh tension control device 30 is connected to the sensor 10, the database 20, and the wire cutter 40, respectively. It is used to acquire the data collected by the sensor 10 and the standard tension data stored in the database 20, and to maintain the standard tension data, such as the set tension value, the standard tension value, and the floating values within various tension ranges, on the wire cutter 40. The wire mesh tension control device 30 is also used to execute the wire mesh tension control method of the present application embodiment to control the wire mesh tension of the wire cutter 40 at different operating stages.
[0057] For example, in this embodiment, the tension value setting includes a first tension value and a second tension value. The first tension value and the second tension value are used to control the tension applied to a first side of the wire mesh and the tension applied to a second side of the wire mesh, respectively. The first side can represent the left side, and the second side can represent the right side. Alternatively, the first side can represent the right side, and the second side can represent the left side. It should be noted that, for ease of explanation, in subsequent embodiments, unless otherwise specified, the left tension value refers to the first tension value, and the right tension value refers to the second tension value. It should also be noted that, unless otherwise specified, the method for adjusting the tension value applies to both the first and second sides simultaneously.
[0058] The wire mesh tension control method of this application embodiment is described below with reference to the accompanying drawings.
[0059] Please see Figure 2 , Figure 2 This is a schematic flowchart illustrating the overall process of the wire mesh tension control method according to an embodiment of this application. The wire mesh tension control method includes the following steps:
[0060] Step 201: Based on the real-time equipment data of the wire cutting machine, determine the operating stage of the wire cutting machine and the corresponding anomaly detection results.
[0061] In some examples, real-time equipment data may include button information, parameter information, and exception information. Button information indicates the operation information of each function button, such as the on / off information of the warm-up button, cutting button, material feeding button, and cutting chamber door button. Parameter information includes wire speed, left and right wire tension, and wire cutter feed speed. Exception information includes abnormal events that occur or are recorded during the entire operation of the wire cutter.
[0062] In some examples, the operating phases include at least one of a first phase, a second phase, a third phase, a fourth phase, and a fifth phase. Standard tension data includes a first setpoint, a tension increment, a second setpoint, and a standard tension value.
[0063] The wire cutter is divided into five stages: Stage 1 represents the wire feeding stage; Stage 2, following Stage 1, represents the preheating stage; Stage 3, following Stage 2, represents the cutting stage; Stage 4, following Stage 3, represents the take-up stage; and Stage 5, following Stage 4, represents the feeding stage. The first setpoint represents the baseline tension throughout the cutting process. This setpoint is fixed and can be changed by the operator on the wire cutter. The tension increment represents the increase in the first setpoint, which can be adjusted based on factors such as the wire manufacturer and wire diameter, and can be maintained on the wire cutter's interface. The second setpoint represents the tension value set for manual take-up. The standard tension value represents the standard tension value set for the current process, which can be changed by the operator on the wire cutter.
[0064] In some embodiments, after obtaining real-time equipment data from the wire cutting machine, the real-time equipment data can be format-converted and cleaned to remove duplicate data, data not configured on the page, and data that does not conform to the data type configured on the page, ensuring the reliability, authenticity, and usability of the data. The format conversion can be to JSON (JavaScript Object Notation) format, a lightweight data exchange format that is easy to read and write, and also easy for machines to parse and generate.
[0065] In some embodiments, step 201 may be implemented by the following steps:
[0066] Step 1: Determine the operating stage of the wire cutting machine based on button and parameter information.
[0067] Specifically, the operating phase is identified internally by the wire tension control device. It can be determined based on the status and parameter information of various buttons collected from the wire cutter. When the operator clicks the corresponding button and the parameters of the wire cutter meet the requirements, the wire tension control device will determine that the wire cutter has entered the corresponding operating phase.
[0068] In some examples, methods for determining the operating phase of the wire cutter as the first phase include:
[0069] If the left tension setting value and the right tension setting value are the same, and the grounding wire button is on, the cutting chamber door is closed, and the absolute value of the wire speed is greater than zero, then the operating stage of the wire cutting machine is determined to be the first stage.
[0070] In other examples, methods for determining the operating phase of the wire cutter as the second phase include:
[0071] If the hot start button is turned on, the wire cutter is confirmed to be in the second stage of operation.
[0072] In other examples, methods for determining the operating phase of the wire cutter as the third phase include:
[0073] If the cutting button is turned on, the wire cutter is confirmed to be in the third stage of operation.
[0074] In other examples, methods for determining the operation phase of the wire cutter as the fourth phase include:
[0075] If the crystal rod is cut through based on real-time equipment data, then the operation stage of the wire cutter is determined to be the fourth stage.
[0076] In other examples, methods for determining the operating phase of the wire cutter as the fifth phase include:
[0077] If the feeding button is turned on, the wire cutter is confirmed to be in the fifth stage of operation.
[0078] Step 2: Based on the anomaly information and parameter information, determine the anomaly detection results corresponding to the running phase.
[0079] For example, the anomaly detection results may include at least one of wire breakage information, wire bonding information, and wire knot information.
[0080] There are several ways to determine the results of anomaly detection. One method is to determine them from the anomaly information displayed in the pop-up window on the wire cutter. For example, when the wire cutter restarts after being stopped, it will display a pop-up window prompting you to click on the anomaly type, at which point the corresponding anomaly information can be captured. Another method is to determine them from the anomaly events reported by the fault monitoring device of the wire cutter. For different alarm codes reported, the anomaly information corresponding to the alarm code can be obtained according to the pre-set correspondence between alarm codes and anomaly types. Yet another method is to perform real-time analysis based on parameter information to analyze anomalies such as wire bonding, wire breakage, and wire knots. For example, wire breakage information can be determined by whether the grounding wire is broken or whether the tension of the left and right wiring drops suddenly; wire bonding information can be determined by whether the grounding wire is broken or whether the cutting direction changes when running to the third stage; and wire knot information can be determined by the current wire quantity in the left storage area obtained when the last fixed wire knot alarm code is received in the third stage.
[0081] The above solution can accurately identify the operating stage of the wire cutting machine and the corresponding abnormal detection results, which facilitates the setting of corresponding tension values according to different stages and situations, thereby improving the response speed and intelligence of wire tension control.
[0082] Step 202: Based on the operating stage of the wire cutter, the abnormal detection results corresponding to the operating stage, and the standard tension data, determine the set tension value corresponding to the operating stage in order to adjust the wire mesh tension of the wire cutter during the operating stage.
[0083] Specifically, different set tension values can be set according to different operating stages and the corresponding abnormal detection results of the operating stages.
[0084] Please see Figure 3 , Figure 3 This is an example flowchart illustrating the wire mesh tension control method according to an embodiment of this application. In some embodiments, the method for determining the set tension value corresponding to the first stage includes:
[0085] Based on the first set value and the tension increment, the set tension value corresponding to the first stage is determined.
[0086] Specifically, based on the first set value, a certain tension increment is added to obtain the set tension value corresponding to the first stage.
[0087] In other embodiments, the method for determining the set tension value corresponding to the second stage includes:
[0088] The set tension value corresponding to the second stage is determined as the first set value.
[0089] Specifically, after the online cutting machine enters the second stage, the set tension value maintained on the online cutting machine needs to be restored from the sum of the first set value and the tension increment to the first set value.
[0090] In some other embodiments, the method for determining the set tension value corresponding to the third stage includes:
[0091] Step 1: Determine the set tension value corresponding to the third stage as the first set value.
[0092] Step two: If the anomaly detection result indicates that the first target anomaly did not occur in the third stage, then the set tension value corresponding to the third stage will continue to be maintained at the first set value. If the anomaly detection result indicates that the first target anomaly occurred in the third stage, then the set tension value corresponding to the third stage will be adjusted to the standard tension value.
[0093] For example, a method for determining that the first target anomaly occurs in the third stage includes:
[0094] The first step is to determine the virtual knot value, actual knot value, wire tension, and wire storage amount based on real-time equipment data.
[0095] Specifically, the virtual wire knot value is a set value input on the wire cutter, while the actual wire knot value, wire tension, and wire storage amount are values monitored in real time during the cutting process. The virtual wire knot value includes the left and right virtual wire knot values, the actual wire knot value includes the left and right actual wire knot values, and the wire storage amount includes the left and right wire storage amounts.
[0096] The second step is to determine the occurrence of the first target anomaly in the third stage if the virtual wire knot value is greater than the actual wire knot value, the wire tension is greater than zero, and the actual wire knot value and the wire storage quantity meet the third preset condition.
[0097] Specifically, the actual knot value and the stored wire quantity satisfying the third preset condition means that the actual knot value meets the threshold range of the stored wire quantity, that is, the difference between the actual knot value and the preset configurable threshold is less than or equal to the stored wire quantity, and the sum of the actual knot value and the preset configurable threshold is greater than or equal to the stored wire quantity.
[0098] For example, the condition of the steel wires on the first and second sides of the wire mesh can be determined separately. If the virtual knot value of the left weld wire is greater than the actual knot value, the weld wire tension is greater than zero, and the actual knot value - preset configurable threshold ≤ left wire storage amount ≤ actual knot value + preset configurable threshold, then the left set tension value corresponding to the third stage is adjusted to the standard tension value. If the virtual knot value of the right weld wire is greater than the actual knot value, the weld wire tension is greater than zero, and the actual knot value - preset configurable threshold ≤ right wire storage amount ≤ actual knot value + preset configurable threshold, then the right set tension value corresponding to the third stage is adjusted to the standard tension value. It can be understood that as long as a first target anomaly occurs on either the first or second side of the wire mesh, a first target anomaly is confirmed to have occurred in the third stage.
[0099] In some other embodiments, the method for determining the set tension value corresponding to the fourth stage includes:
[0100] If the anomaly detection result indicates that no second target anomaly occurred in the third stage, then the fourth stage is determined to be the first operating mode, and the set tension value corresponding to the fourth stage is determined to be the first set value. If the anomaly result indicates that a second target anomaly occurred in the third stage, then the fourth stage is determined to be the second operating mode, and the set tension value corresponding to the fourth stage is determined to be the second set value.
[0101] Specifically, the first operation mode is automatic wire reeling, and the second operation mode is manual wire reeling, which involves manually cutting the wire mesh and lifting the material. If no second target abnormality occurs during the third stage of cutting, the wire will be automatically reeled in. If a second target abnormality occurs during the third stage of cutting, a pop-up window will prompt for manual wire reeling.
[0102] For example, a method for determining that the second target anomaly occurs in the third stage includes:
[0103] If the abnormality detection result indicates that the wire mesh of the wire cutter has been broken, then the second target abnormality is determined to have occurred in the third stage.
[0104] In some other embodiments, the method for determining the set tension value corresponding to the fifth stage includes:
[0105] The set tension value corresponding to the fifth stage is determined as the standard tension value.
[0106] Specifically, during the material feeding stage, the set tension value will be changed to the standard tension value. After the change, the tension shielding state will also be activated. The tension shielding state is used to release the control that requires the left and right tensions to be consistent.
[0107] In some embodiments, after determining the set tension value corresponding to the operating stage, the set tension value is fed back to the wire cutter via control commands, so as to control the setting and modification of the corresponding input parameters of the wire cutter through the set tension value, so as to ensure that the wire cutter operates in the optimal tension state in each operating stage.
[0108] In some examples, after controlling the wire tension of the wire cutter in the third stage based on the set tension value corresponding to the third stage, the method of this application embodiment may further include:
[0109] Step 1: Determine the current feed position of the wire cutting machine based on real-time equipment data.
[0110] Step 2: If the current feed position meets the first preset condition and the set tension value meets the second preset condition, then control the wire cutter to stop and prompt that the starting tension is abnormal.
[0111] For example, the first preset condition refers to the current feed position being between -0.5mm and +0.5mm. When the current feed position is between -0.5mm and +0.5mm, it indicates that the wire cutter is in the initial cutting state. The second preset condition refers to the left and right set tension values being inconsistent, and / or the left set tension value being less than a set threshold, and / or the right set tension value being less than a set threshold. When the set tension value meets the second preset condition, it indicates that the tension setting value of the wire cutter may have been arbitrarily modified. That is, if it is detected that the tension setting value may have been arbitrarily modified when the wire cutter has just started cutting, the wire cutter will be stopped, and an abnormal starting tension will be indicated to avoid continued cutting affecting quality.
[0112] The above solution can avoid quality problems caused by unauthorized changes to the set tension value of the wire cutting machine.
[0113] In other words, the third stage first checks whether the tension setting is abnormal at the start of cutting. If abnormal, the wire cutter stops and a pop-up window indicates an abnormal tension. During cutting, the system checks for wire breakage based on real-time tension changes on both sides, tension enable, and grounding conditions. Finally, it records other abnormalities, such as wire bonding and jumpers, to inform the operation mode selection for the fourth stage.
[0114] It is understood that the method of this application embodiment can automatically and accurately determine the operating stage of the wire cutter and set the set tension value for each operating stage, and issue instructions to the wire cutter and update the set tension value, thereby ensuring that the wire cutter always operates under the best tension state, improving the cutting quality. In addition, the entire tension control process does not require manual intervention and can be operated automatically and imperceptibly, ensuring the stability and efficiency of the cutting process, and simplifying the operation process, greatly improving production efficiency and safety.
[0115] Accordingly, this application also provides a wire mesh tension control device. Please refer to [link / reference].
