Description

Technical Field

[0001] This invention relates to the field of wire harness processing technology, and in particular to an intelligent crimping pressure monitoring system and method. Background Technology

[0002] Crimping machines are common traditional equipment in wire harness manufacturing, used to connect terminals and wires through physical crimping. The crimping pressure is typically achieved manually by adjusting the die height. Due to the wide variety of wire harness products and the varying ideal pressures required, frequent die adjustments are necessary. However, there are no clear guidelines for these adjustments, and the crimping machine itself cannot provide pressure feedback, making the adjustment process entirely reliant on the operator's experience. Operators can only determine a roughly suitable die height through trial and error, involving repeated adjustments and crimping tests. This process is not only time-consuming and labor-intensive but also wastes valuable raw materials for crimping tests. Furthermore, the results are highly uncertain and inconsistent, easily leading to inaccurate pressure adjustments and defects in wire harness products, such as shallow or deep crimping, or even broken wires, thus causing product quality problems.

[0003] With increasing awareness of quality, customers are not only concerned with the quality of the final product, but also pay more attention to the recording of parameter data for each key process step. However, as traditional machines, crimping machines typically lack data input / output interfaces and effective data acquisition and output capabilities, making it impossible to monitor the crimping process in real time. Therefore, the lack of real-time online monitoring of the crimping process in existing technologies leads to an inability to consistently guarantee product quality. Summary of the Invention

[0004] This invention provides an intelligent crimping pressure monitoring system and method, aiming to solve the problem that the lack of real-time online monitoring of the crimping process in the prior art leads to the inability to guarantee stable product quality.

[0005] In a first aspect, embodiments of the present invention provide an intelligent crimping pressure monitoring system, which includes: a crimping machine, a pressure sensor, a data acquisition unit, and a data processing server; The pressure sensor is mounted on the crimping machine, the pressure sensor is electrically connected to the data acquisition unit, and the data acquisition unit is communicatively connected to the data processing server. The pressure sensor is used to collect pressure signals on the crimping die in the crimping machine in real time. The data acquisition unit is used to acquire the pressure signal output by the pressure sensor during the crimping process of the crimping machine at a high sampling rate, and process it to obtain the maximum pressure value; The data processing server is used to obtain equipment information and current production order information, and to obtain the pressure standard range corresponding to the order information; The data processing server is also used to compare the maximum pressure value with the pressure standard range, and generate an alarm control signal when it is determined that the maximum pressure value exceeds the pressure standard range, or generate crimping data based on the equipment information, the order information, and the maximum pressure value when it is determined that the maximum pressure value does not exceed the pressure standard range.

[0006] Secondly, embodiments of the present invention also provide an intelligent crimping pressure monitoring method, applied to the intelligent crimping pressure monitoring system as described in the first aspect, the method comprising: The data processing server obtains equipment information and current production order information, and obtains the pressure standard range corresponding to the order information; The pressure sensor collects the pressure signal on the crimping die in the crimping machine in real time; The crimping machine performs a crimping operation in response to a crimping start command; The data acquisition unit acquires the pressure signal output by the pressure sensor during the crimping process of the crimping machine at a high sampling rate, and processes it to obtain the maximum pressure value; The data processing server compares the maximum pressure value with the pressure standard range; If the data processing server determines that the maximum pressure value exceeds the pressure standard range, it generates an alarm control signal. If the data processing server determines that the maximum pressure value does not exceed the pressure standard range, it generates crimping data based on the equipment information, the order information, and the maximum pressure value.

[0007] This invention provides an intelligent crimping pressure monitoring system and method. The system includes a crimping machine, a pressure sensor, a data acquisition unit, and a data processing server. The pressure sensor collects pressure signals from the crimping die in the crimping machine in real time. The data acquisition unit collects the pressure signals output by the pressure sensor during the crimping process at a high sampling rate and processes them to obtain the maximum pressure value. The data processing server acquires equipment information, current production order information, and the corresponding pressure standard range. When the maximum pressure value exceeds the pressure standard range, an alarm control signal is generated; or when the maximum pressure value does not exceed the pressure standard range, crimping data is generated based on the equipment information, order information, and maximum pressure value. This invention monitors the maximum pressure value of the crimping machine in real time during the crimping process and automatically compares it with the pressure standard range. This real-time online monitoring of the crimping process enables abnormal alarms, facilitates timely detection of products with unqualified crimping pressure, ensures product quality, and allows for quality traceability through crimping data.

Detailed Implementation

[0010] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. 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.

[0012] It should also be understood that the terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the invention. As used in this specification and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.

[0013] It should also be further understood that the term "and / or" as used in this specification and the appended claims refers to any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0014] See Figure 1 and Figure 2 , Figure 1 This is a schematic block diagram of an intelligent crimping pressure monitoring system provided in an embodiment of the present invention; Figure 2This is a schematic block diagram of an intelligent crimping pressure monitoring system provided in another embodiment of the present invention.

[0015] This invention provides an intelligent crimping pressure monitoring system, comprising: a crimping machine 1, a pressure sensor 2, a data acquisition unit 3, and a data processing server 4; the pressure sensor 2 is disposed on the crimping machine 1, the pressure sensor 2 is electrically connected to the data acquisition unit 3, and the data acquisition unit 3 is communicatively connected to the data processing server 4; the pressure sensor 2 is used to collect pressure signals on the crimping mold 11 in the crimping machine 1 in real time; the data acquisition unit 3 is used to collect the pressure signals output by the pressure sensor 2 during the crimping process of the crimping machine 1 at a high sampling rate, and process them to obtain the maximum pressure value; the data processing server 4 is used to obtain equipment information and order information of the current production order, and obtain the pressure standard range corresponding to the order information; the data processing server 4 is also used to compare the maximum pressure value with the pressure standard range, and generate an alarm control signal when it is determined that the maximum pressure value exceeds the pressure standard range, or generate crimping data based on the equipment information, the order information, and the maximum pressure value when it is determined that the maximum pressure value does not exceed the pressure standard range.

[0016] In this embodiment, refer to Figure 1 The crimping machine 1 includes a crimping die 11 and a die base 12 that cooperate with each other. The die base 12 is used to hold the raw materials (i.e., wires and terminals) to be crimped. The crimping die 11 moves towards the die base 12 under the action of a drive mechanism, applying pressure to the raw materials located therebetween to complete the crimping. The pressure sensor 2 is specifically installed on the crimping die 11 in the crimping machine 1, and is used to collect the pressure signal on the crimping die 11 in the crimping machine 1 in real time.

[0017] Furthermore, due to the instantaneous and high-speed nature of the crimping action of the crimping machine 1, using ordinary data acquisition methods (such as reading through the general serial port of an industrial control computer) can lead to data distortion or loss of key information due to insufficient sampling rate or slow response speed, making it difficult to accurately capture the pressure peak. Therefore, this embodiment of the invention employs a data acquisition device 3 with a settable high sampling rate. This data acquisition device 3 can be set to software triggering or channel triggering. By electrically connecting this data acquisition device 3 to the pressure sensor 2, during the crimping process of the crimping machine 1, the data acquisition device 3 can continuously sample the pressure signal output by the pressure sensor 2 during the crimping process at a preset high sampling rate. This allows for the complete recording of the entire waveform from pressure rise to fall within the extremely short duration of the crimping action, and the accurate calculation of the maximum pressure value from this waveform. This avoids the loss of sampled data due to the rapid crimping action of the crimping machine 1, ensuring accurate capture of the maximum pressure value. Preferably, the data acquisition device 3 is a DAQ125 data acquisition device.

[0018] The data processing server 4 is communicatively connected to the data collector 3. The data processing server 4 acquires equipment information and current production order information. The order information indicates the raw materials being crimped, allowing it to filter the corresponding pressure standard range from a preset pressure standard range based on the raw materials in the order information. Furthermore, the equipment information is a unique identifier for the crimping machine 1. The equipment information and order information can establish a binding relationship between the crimping machine 1 and the production order, enabling the crimping data generated after crimping to be associated with the corresponding production order, achieving quality traceability. The pressure standard range indicates the normal standard range of the required pressure value for the raw materials being crimped, facilitating subsequent judgment of whether the maximum pressure value during the crimping process is qualified. Specifically, the data processing server 4 responds to scanning operations on the preset equipment code and the flow code on the current production order to obtain equipment information and order information. When the data processing server 4 receives the maximum pressure value uploaded by the data collector 3, it automatically compares the maximum pressure value with the corresponding pressure standard range to determine whether the pressure of this crimping is qualified, achieving real-time online monitoring of the crimping process. If data processing server 4 determines that the maximum pressure value exceeds the pressure standard range, it indicates that the pressure of this crimping is unqualified and abnormal. An alarm control signal is then generated to remind relevant personnel to promptly identify products with unqualified pressure and to repair the crimping machine 1 in a timely manner. If data processing server 4 determines that the maximum pressure value does not exceed the pressure standard range, it indicates that the pressure of this crimping is qualified and the quality of the produced product is qualified. Based on equipment information, order information, and the maximum pressure value, crimping data is generated, enabling the crimping data to be archived and traced according to production orders. This traceability of the crimping process for production orders facilitates quality control of the products.

[0019] In a more specific embodiment, the intelligent crimping pressure monitoring system further includes a first display table 5, which is communicatively connected to the data processing server 4, and is used to display the maximum pressure value transmitted by the data processing server 4.

[0020] Furthermore, the first display table 5 is a digital display table connected to the data processing server 4 via an RS-485 bus.

[0021] In this embodiment, refer to Figure 2 A first display 5 is connected to the data processing server 4 to display the maximum pressure value transmitted by the data processing server 4. This allows relevant personnel to directly observe the value displayed on the first display 5 to determine if there are any abnormalities in the crimping pressure. Preferably, the first display is a digital display, which is connected to the data processing server 4 via an RS-485 bus.

[0022] In a more specific embodiment, the intelligent crimping pressure monitoring system further includes a second display table 6, which is electrically connected to the pressure sensor 2. The second display table 6 is used to display the pressure value corresponding to the pressure signal output by the pressure sensor 2 in real time.

[0023] In this embodiment, refer to Figure 2 The second display 6 is electrically connected to the pressure sensor 2 to provide real-time and intuitive feedback on the pressure value corresponding to the pressure signal output by the pressure sensor 2. This pressure value represents the torque value on the pressing mold 11. In the crimping machine 1 adjustment mode, the second display 6 can assist operators in observing and adjusting the crimping machine 1 to the target pressure value. Operators adjust the height of the crimping die 11 in the crimping machine 1 by observing the changes in the values ​​displayed on the second display 6, ensuring that the initial torque value of the crimping die 11 is accurately set to the target pressure value. For example, when changing the product model or die, operators may know from process requirements that the initial torque value on the crimping die 11 needs to reach 100N (i.e., the target pressure value is 100N). Operators adjust the height of the crimping die 11 in the crimping machine 1 by turning the relevant screws while observing the real-time values ​​displayed on the second display 6. When the real-time value displayed on the second display 6 reaches 100N, the screws are stopped, thus completing the setting of the crimping die 11 height. This solves the problems of low adjustment efficiency and high material trial costs caused by relying entirely on personal experience and constant trial and error in traditional adjustment methods. This greatly improves the accuracy and efficiency of adjustment and significantly saves on adjustment materials. Secondly, in the crimping production mode of crimping machine 1, the stability of the value continuously displayed on the second display 6 can indirectly reflect the hardware status of crimping machine 1. When the hardware of crimping machine 1 is normal, the value continuously displayed on the second display 6 is the target pressure value set after machine adjustment. However, due to the impact force during the crimping process of crimping machine 1, the crimping mold 11 may experience slight loosening or wear. These changes will cause the torque value on the crimping mold 11 to change. Once the hardware of crimping machine 1 malfunctions, the value displayed on the second display 6 will change immediately. Therefore, when relevant operators observe the change in the value displayed on the second display 6, they can quickly determine that the hardware status of crimping machine 1 is abnormal, and then repair crimping machine 1 in time to avoid batch quality accidents.

[0024] In a more specific embodiment, the intelligent crimping pressure monitoring system further includes an alarm device 7, which is communicatively connected to the data processing server 4, and is used to perform an alarm action in response to the alarm control signal.

[0025] In this embodiment, refer to Figure 2The alarm device 7 is connected to the data processing server 4. After the data processing server 4 detects that the maximum pressure value exceeds the pressure standard range and generates an alarm control signal, the alarm device 7 responds to the alarm control signal and executes an alarm action, thereby promptly reminding relevant personnel that the pressure of this crimping is unqualified and that the crimping machine 1 needs to be repaired in time.

[0026] In a more specific embodiment, the alarm device 7 includes an I / O module 71 and a buzzer 72, the buzzer 72 being communicatively connected to the data processing server 4 through the I / O module 71.

[0027] In this embodiment, refer to Figure 2 The alarm device 7 consists of an I / O module 71 and a buzzer 72. The data processing server 4 communicates with the buzzer 72 through the I / O module 71. After receiving the alarm control signal output by the data processing server 4, the I / O module 71 drives the connected buzzer 72 to sound, alerting relevant personnel through sound. Alternatively, the alarm device 7 can also consist of an I / O module 71 and an indicator light. After receiving the alarm control signal output by the data processing server 4, the I / O module 71 drives the connected indicator light to illuminate, alerting relevant personnel through light.

[0028] In a more specific embodiment, the intelligent crimping pressure monitoring system further includes a data storage device 8, which is communicatively connected to the data processing server 4, and is used to store the crimping data.

[0029] In this embodiment, refer to Figure 2 The system uses a data storage device 8 to communicate with a data processing server 4. After generating the compressed data, the data processing server 4 stores the compressed data in the data storage device 8. By aggregating the compressed data in the data storage device 8, it can be queried by other terminals. The data storage device 8 can be a cloud server or a local database server.

[0030] This invention provides an intelligent crimping pressure monitoring system, comprising a crimping machine 1, a pressure sensor 2, a data acquisition unit 3, and a data processing server 4. The system monitors the maximum pressure value of the crimping machine 1 in real time during the crimping process through the pressure sensor 2 and the data acquisition unit 3, and automatically compares the maximum pressure value with the pressure standard range through the data processing server 4. This real-time online monitoring of the crimping process enables abnormal alarms, facilitates timely detection of products with unqualified pressure, ensures product quality, and enables quality traceability through crimping data.

[0031] like Figure 3 As shown, Figure 3This is a flowchart illustrating an intelligent crimping pressure monitoring method according to an embodiment of the present invention. The present invention also provides an intelligent crimping pressure monitoring method applicable to any embodiment of the aforementioned intelligent crimping pressure monitoring system, comprising the following steps S11-S17.

[0032] S11. The data processing server obtains equipment information and current production order information, and obtains the pressure standard range corresponding to the order information.

[0033] In this embodiment, before starting the crimping machine to perform the crimping operation, the data processing server obtains equipment information and current production order information. The order information indicates the raw materials to be crimped, allowing the server to filter the corresponding pressure standard range from a preset pressure standard range based on the raw materials in the order information. Furthermore, the equipment information serves as a unique identifier for the crimping machine. A binding relationship between the crimping machine and the production order can be established through the equipment information and order information, enabling the crimping data generated after crimping to be associated with the corresponding production order, thus achieving quality traceability. The pressure standard range indicates the normal standard range of the required pressure value for the raw materials currently being crimped, facilitating subsequent judgment of whether the maximum pressure value during the crimping process is qualified based on the normal standard range.

[0034] In one embodiment, the data processing server acquires device information and current production order information, including: The data processing server responds to a scan operation on a preset device code to obtain the device information; The data processing server responds to the scanning operation of the transfer code on the current production order to obtain the order information.

[0035] In this embodiment, the data processing server obtains equipment information and order information in response to scanning operations on a preset device code and a transfer code on the current production order. Specifically, the data processing server is communicatively connected to a scanning device. The data processing server obtains equipment information by scanning the device code set on the pressure sensor and obtains order information by scanning the transfer code on the current production order.

[0036] S12. The pressure sensor collects the pressure signal on the crimping die in the crimping machine in real time.

[0037] In this embodiment, the pressure sensor is powered on and collects the pressure signal on the crimping die in the crimping machine in real time.

[0038] S13, The crimping machine performs a crimping operation in response to the crimping start command.

[0039] In this embodiment, the crimping machine responds to the crimping start command and begins to perform the crimping operation. Specifically, the drive mechanism in the crimping machine responds to the crimping start command by moving the crimping die toward the die base, causing the crimping die to apply pressure to the raw material placed on the die base, thereby completing the crimping.

[0040] S14. The data acquisition unit acquires the pressure signal output by the pressure sensor during the crimping process of the crimping machine at a high sampling rate, and processes it to obtain the maximum pressure value.

[0041] In this embodiment, during the crimping process, the data acquisition unit continuously samples the pressure signal output by the pressure sensor at a preset high sampling rate. This allows for the complete recording of the entire waveform of pressure rising and falling within the extremely short duration of the crimping action. The maximum pressure value is then accurately calculated from this waveform, preventing sample loss due to the rapid crimping action and ensuring accurate capture of the maximum pressure value. Preferably, the data acquisition unit is a DAQ125 data acquisition unit.

[0042] S15. The data processing server compares the maximum pressure value with the pressure standard range.

[0043] S16. If the data processing server determines that the maximum pressure value exceeds the pressure standard range, it generates an alarm control signal.

[0044] S17. If the data processing server determines that the maximum pressure value does not exceed the pressure standard range, it generates crimping data based on the equipment information, the order information, and the maximum pressure value.

[0045] In this embodiment, when the data processing server receives the maximum pressure value uploaded by the data collector, it automatically compares the maximum pressure value with the corresponding pressure standard range to determine whether the pressure of this crimping is qualified, thus achieving real-time online monitoring of the crimping process. If the data processing server determines that the maximum pressure value exceeds the pressure standard range, it indicates that the pressure of this crimping is unqualified and abnormal, and generates an alarm control signal to remind relevant personnel to promptly identify products with unqualified pressure and repair the crimping machine in a timely manner. If the data processing server determines that the maximum pressure value does not exceed the pressure standard range, it indicates that the pressure of this crimping is qualified and the quality of the produced product is qualified. Then, it generates crimping data based on equipment information, order information, and the maximum pressure value, enabling the crimping data to be archived and traced according to production orders. This makes the crimping process of production orders traceable, which is beneficial for product quality control.

[0046] In one embodiment, step S17 includes: If the data processing server determines that the maximum pressure value does not exceed the pressure standard range, it obtains the current system time and combines the equipment information, the order information, the maximum pressure value, and the current system time into the crimping data.

[0047] In this embodiment, after determining that the maximum pressure value does not exceed the pressure standard range, the data processing server obtains the current system time and combines the equipment information, order information, maximum pressure value, and current system time into crimping data. This links the equipment information, order information, maximum pressure value, and current system time together, so that the crimping process can be viewed through the production order later, thus achieving quality traceability.

[0048] In one embodiment, after step S14, the method further includes: The data processing server transmits the maximum pressure value to the first display table so that the maximum pressure value can be displayed on the first display table.

[0049] In this embodiment, the maximum pressure value transmitted by the data processing server is displayed on a first display, allowing relevant personnel to directly observe the value displayed on the first display to determine if there is any abnormality in the crimping pressure. Preferably, the first display is a digital display, which is connected to the data processing server via an RS-485 bus.

[0050] In one embodiment, after step S12, the method further includes: The second display shows the pressure value corresponding to the pressure signal output by the pressure sensor in real time.

[0051] In this embodiment, a second display is used to provide real-time and intuitive feedback on the pressure value corresponding to the pressure signal output by the pressure sensor. This pressure value represents the torque value on the pressing die. In the crimping machine's adjustment mode, the second display helps operators observe and adjust the crimping machine to the target pressure value. Operators adjust the height of the crimping die by observing the changes in the values ​​displayed on the second display, ensuring the initial torque value of the crimping die is accurately set to the target pressure value. For example, when changing product models or dies, operators may know from process requirements that the initial torque value of the crimping die needs to reach 100N (i.e., the target pressure value is 100N). Operators adjust the height of the crimping die by turning the relevant screws while observing the real-time values ​​displayed on the second display. When the real-time value on the second display reaches 100N, they stop turning the screws, thus completing the setting of the crimping die height. This solves the problems of low adjustment efficiency and high material trial costs caused by relying entirely on personal experience and constant trial and error in traditional adjustment methods. It greatly improves the accuracy and efficiency of adjustment and significantly saves on adjustment materials. Secondly, in the crimping production mode of the crimping machine, it can also be understood that when the crimping operation is completed in step S13, the stability of the value continuously displayed on the second display table can indirectly reflect the hardware status of the crimping machine. When the crimping machine hardware is normal, the value continuously displayed on the second display table is the target pressure value set after the machine is adjusted. However, due to the impact force during the crimping process, the crimping mold may experience slight loosening or wear. These changes will cause the torque value on the crimping mold to change. Once the crimping machine hardware malfunctions, the value displayed on the second display table will change immediately. Therefore, when the relevant operators observe the change in the value displayed on the second display table, they can quickly determine that the hardware status of the crimping machine is abnormal, and then repair the crimping machine in time to avoid batch quality accidents.

[0052] In one embodiment, after step S16, the method further includes: The alarm device responds to the alarm control signal and performs an alarm action.

[0053] In this embodiment, after the data processing server detects that the maximum pressure value exceeds the pressure standard range and generates an alarm control signal, the alarm device responds to the alarm control signal and executes an alarm action, thereby promptly reminding relevant personnel that the pressure of this crimping is unqualified and that the crimping machine needs to be repaired in a timely manner.

[0054] Furthermore, the alarm device consists of an I / O module and a buzzer. The data processing server communicates with the buzzer via the I / O module. After receiving the alarm control signal output from the data processing server, the I / O module drives the connected buzzer to sound, alerting relevant personnel through sound. Alternatively, the alarm device can also consist of an I / O module and an indicator light. After receiving the alarm control signal output from the data processing server, the I / O module drives the connected indicator light to illuminate, alerting relevant personnel through light.

[0055] In one embodiment, after step S17, the method further includes: the data processing server transmitting the crimped data to a data storage device to store the crimped data in the data storage device.

[0056] In this embodiment, after generating the crimped data, the data processing server stores the crimped data in a data storage device. By aggregating the crimped data in the data storage device, it facilitates querying by other terminals. The data storage device can be a cloud server or a local database server.

[0057] The intelligent crimping pressure monitoring method provided in this invention can be applied to any embodiment of the aforementioned intelligent crimping pressure monitoring system. It monitors the maximum pressure value of the crimping machine in real time during the crimping process through a pressure sensor and a data acquisition device, and automatically compares the maximum pressure value with the pressure standard range through a data processing server. It can monitor the crimping process online in real time, realize abnormal alarms, facilitate the timely detection of products with unqualified pressure, ensure product quality, and realize quality traceability through crimping data.

[0058] It should be understood that the sequence number of each step in the above embodiments does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present invention.

[0059] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and these modifications or substitutions should all be covered within the scope of protection of the present invention.
