Description

Technical Field

[0002] Wire harnesses and cables are the "electrical ties" and "intelligent manufacturing innovation engines" of mechanical component structures. Wire harness and cable processing is an important part of the mechanical manufacturing industry. The field of mechanical manufacturing technology, including the wire harness and cable processing industry, is undergoing significant and rapid innovations. While technological innovations have brought progress to the industry, some unavoidable and non-ignorable drawbacks have gradually emerged. At present, the more advanced edge devices and machine tools used for wire harness and cable processing on the market are equipped with PLC numerical control systems. The PLC numerical control system can collect important data such as the operation information of the main equipment, the status of the production line, and the processing information of the product, and remotely send the equipment, production line, and product related information to the background server through the networking function, thereby realizing the operation monitoring, environmental monitoring, product tracking, quality control management, visual management and many other functions in the process of wire harness and cable processing, which can greatly improve production efficiency.

[0003] However, wire harness and cable processing machinery and equipment is an expensive and relatively fixed asset. The upgrade or renewal of fixed assets will be accompanied by huge cost consumption, so the process of renewal and replacement is difficult to keep up with the speed of technological innovation. Due to complex reasons such as blind market expansion and high upgrade costs, there are still a large number of wire harness and cable processing equipment on the market that do not have PLC numerical control systems or other similar types of systems.

[0034] The present application will be described in detail below in conjunction with the various embodiments shown in the accompanying drawings. However, these embodiments do not limit the present application, and any structural, methodological, or functional changes made by a person of ordinary skill in the art based on these embodiments are all within the scope of protection of the present application.

It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein, for example.

[0036] Embodiment 1: Figure 1 As shown, the present invention provides an intelligent integration method for wire harness cable processing equipment, characterized in that the method comprises:

[0037] S100, constructing an electrical drawing library for wire harness and cable processing equipment, wherein the electrical drawing library for wire harness and cable processing equipment includes electrical drawings of wire harness and cable processing equipment and corresponding transformation plans.

[0038] There are many types of wire harness and cable processing equipment, such as shell inserters, laser stripping machines, glue coating and dispensing machines, terminal punching machines, color sequence splitters, etc. Even for the same type of equipment, different manufacturers will improve the equipment, and due to product copyright or product patent issues, the electrical diagrams of wire harness and cable processing equipment are complex and diverse, with significant differences. Constructing an electrical drawing library for wire harness and cable processing equipment, including the electrical drawings of wire harness and cable processing equipment and the corresponding modification plans, can provide a modifiable upgrade template for equipment modification. In the event that the electrical drawings of a certain processing equipment are lost or the electrical performance changes after long-term use, the staff can also test the processing equipment, and re-establish the corresponding electrical drawings based on the obtained test data, and then place them into the electrical drawing library.

[0039] S110, receiving the electrical drawings of the equipment to be upgraded, and if the electrical drawings of the equipment to be upgraded exist in the constructed electrical drawings library of the wire harness and cable processing equipment, recommending the corresponding transformation plan to the user based on the existing electrical drawings library of the wire harness and cable processing equipment; otherwise, identifying the electrical drawings of the equipment to be upgraded, and generating a preliminary transformation plan based on the identified electrical drawings of the equipment to be upgraded;

[0040] The electrical drawing library of wire harness and cable processing equipment is a dynamically updated database. If there is no corresponding electrical drawing for the equipment to be upgraded, a modification plan should be designed to expand the electrical drawing library of wire harness and cable processing equipment; if there is a corresponding drawing in the electrical drawing of the equipment to be upgraded, the corresponding modification plan can be directly used to implement the equipment modification. Due to the large number of types of wire harness and cable processing equipment and the complexity and variety of different improvement methods, in most cases, when facing a processing equipment to be upgraded, the identification and analysis of the drawings should be completed first. There are three common drawing search methods: equipment model similarity comparison, drawing similarity comparison, key component comparison, etc., which are used to determine whether there is a corresponding drawing in the drawing library. In practical applications, the key component comparison method is widely used. Compared with the drawing similarity, the comparison effect is relatively simple and efficient, and compared with the equipment model similarity comparison, the comparison effect is relatively compatible and more in line with the actual situation. Specifically, based on the needs of equipment work information collection, the user determines a certain type of key electrical elements, or determines the electrical elements of a certain key area, or specifies specific electrical elements or specifies other types of electrical elements, so as to compare only the above-mentioned specified electrical elements as the basis for drawing search. If the electrical drawings of the equipment to be upgraded exist in the built electrical drawings library of the wire harness and cable processing equipment, the corresponding transformation plan based on the existing electrical drawings library of the wire harness and cable processing equipment is recommended to the user; otherwise, the electrical drawings of the equipment to be upgraded are further identified and analyzed based on the identification processing step. The identification processing of this step includes:

[0041] S112, constructing an electrical element graph feature library, wherein the electrical element graph feature library includes transformable electrical elements and feature vectors of corresponding electrical elements.

[0042] The electrical element diagram is generally stable. Due to technological changes or non-standardization of the improvement process, the electrical element diagram will change. Not all types of electrical elements should be placed in the electrical element diagram feature library. The electrical element diagram stored in the electrical element diagram feature library has the following characteristics: (1) including standard and non-standard electrical elements; (2) having upgrade value; (3) being modifiable. For equipment that has no monitoring requirements (such as conventional rheostats, voltage regulator modules, adapter modules and other electrical components), or has no possibility of modification in design (such as conventional resistors, capacitors, wires and other simple electrical components), or has a high cost of modification (such as components with complex wiring and difficult disassembly), it is not suitable to be placed in the feature library. The electrical element diagram feature library contains electrical elements that have modification value and can be modified, and the feature vectors of the corresponding electrical elements.

[0043] S114, determining the electrical drawing format of the device to be upgraded, if the drawing format is a compatible format, directly reading the electrical elements and basic information of the electrical elements in the electrical drawing of the device to be upgraded based on the compatible software; if the drawing format is an incompatible format, converting the drawing format into a picture format and obtaining the scale information of the electrical drawing of the device to be upgraded, determining the element extraction frame size based on the scale information, traversing the image data in the electrical drawing of the device to be upgraded in the picture format according to the element extraction frame size, extracting the image data feature vector, calculating the similarity between the extracted image data feature vector and the feature vector of the electrical element in the electrical element map feature library, when the similarity exceeds a preset threshold, the image data is identified as an electrical element, and the corresponding electrical element basic information is assigned as the electrical element basic information of the corresponding electrical element in the electrical element map feature library;

[0044] The formats of equipment electrical drawings are divided into two situations: those that can be directly recognized and read by software and those that cannot be directly recognized and read. The former is a compatible format, and the electrical elements and basic information of the electrical elements in the electrical drawings of the equipment to be upgraded can be read based on compatible software; the latter is an incompatible format and needs to be read based on a special method. The drawing format of the old equipment may not be compatible with the existing drawing software due to technological innovation, or it may only be a picture format such as JPG or PNG, and it is more common that it cannot be directly read. For electrical drawings in incompatible formats, they can be converted into image formats first, so that the electrical elements in the drawings can be read based on existing OCR technology, image recognition technology, etc., to determine whether they belong to electrical elements with improvement value in the electrical element diagram feature library. A typical example is to identify any electrical elements related to switching quantities as electrical elements to be modified. After modification, data information on the switch on and off conditions of the equipment during operation can be collected based on the modified electrical elements.

[0045] S116, determining a transformation plan based on identifying each electrical element obtained from the electrical drawing of the equipment to be upgraded and the basic information of the corresponding electrical element.

[0046] The transformation plan includes: determining the electrical elements to be transformed, determining the target electrical elements based on the transformation mapping table, and modifying the electrical drawings of the equipment to be upgraded based on the target electrical elements; adding a common function module to the electrical drawings of the equipment to be upgraded based on the user configuration to obtain the electrical drawings of the upgraded equipment;

[0047] In a preferred example, the common function modules include a barcode scanning gun function, a temperature / humidity detection function, a vibration / displacement detection function, a rotation speed / counting function, a monitoring module, a communication module, and an alarm module.

[0048] S120, optimizing and configuring the preliminary transformation plan according to user needs, adding the optimized preliminary transformation plan as sample data to the electrical drawing library of the wiring harness and cable processing equipment, and recommending it to the user; the user transforms the equipment based on the received optimized transformation plan;

[0049] The automatically generated modification plan may not be the optimal modification plan. In one example, for the terminal crimping machine in the wire harness and cable processing equipment, its original design drawing contains several switching elements, each of which generates switching information during the processing to control the processing process. The automatically generated modification plan will recommend to the user to select specific types and models of hardware (such as optocoupler relays) to pre-process the signal based on the identified switching elements or the identified processing signal output line positions. However, in actual work, we found that not all switching information is important. For example, some redundantly designed switching signals based on safety considerations are not necessary for working status judgment; for example, for non-important and negligible work, it can be cancelled during the configuration process based on cost or other considerations; for example, the application of common function modules is optimized and configured based on actual user needs.

[0050] After receiving the optimal transformation plan, the wire harness and cable processing equipment will be transformed according to the recommended transformation plan. Figure 3 As shown, it is an example diagram of the modification of the terminal crimping machine of the wire harness and cable processing equipment. Specifically, after determining the output line position or switch signal of the equipment processing signal, select the recommended type / model of optocoupler relay, such as JOC-3FF-SZ TONGLING Tongling signal power relay, pre-process the signal, attach a step-down / voltage regulation module, such as 2596-SDC, and adapt the voltage; send the on / off signal to the proximal receiving module with the adapted voltage; the proximal receiving module can be a suitable programmable single-chip microcomputer device, which receives the collected voltage signal, and performs data processing to identify it as information corresponding to the working status of the terminal crimping machine. In the above process, there are multiple groups of outputs for the output line position or switch signal of the equipment processing signal, and the working status they represent has different meanings. In addition Figure 3 In addition to the modification examples, according to the recommended modification plan, a vibration detector can be attached to the casing of the cable tie winding machine to detect whether there is abnormal vibration during the operation of the equipment; or a temperature sensor can be set near the module or module used for electronic temperature control design of the slitting tool to detect whether there is temperature abnormality during the operation; or a speed detector can be set on the winding rotor to determine the current operating speed of the equipment.

[0051] In particular, in order to monitor the product processing line, the present invention creatively sets a barcode scanner at the end equipment of the product processing line based on the recommended modification plan, and performs barcode imprinting on batch products, production orders, and finished product material numbers, and associates and binds all the equipment information collected in the processing flow with the barcode. In this way, under normal circumstances, it is easy to trace any processing data of the product in the processing flow, making it possible to find and analyze the reasons for the good or poor quality of the product, thereby significantly improving the production efficiency of the equipment. This has demonstrated its advantages in the actual application of wire harness cable processing equipment.

[0052] S130, during the operation of the modified wire harness and cable processing equipment, automatically collect information corresponding to the working status of the equipment, process the information according to the template style and send it to the background server for storage; the near-end display device displays the processed information based on the visual operation interface; the background server stores and displays the processed information.

[0053] The processing of the working status data sequence based on certain rules can be displayed in various friendly and convenient forms. For example, the template style can be designed in the form of a report to screen and display key data and specific data, realize unattended data recording, and digitize the report; or the template style can be designed as a chart template to elegantly present the equipment working data in the form of pie charts, historical curve charts, bar charts, etc.; or the equipment operation rules can be mined through big data models to analyze under which working conditions the yield or inferior rate is higher, or other operation rules can be analyzed.

[0054] In a preferred embodiment, the near-end display device can select an ESP32S3 chip equipped with a network card, a Bluetooth / WIFI module, an AI support module, and a 2.4-inch display screen. An interactive APP is built in the chip module, and the AI ​​support module is used for big data processing and artificial intelligence model configuration; the network card module is used for device networking to achieve data transmission; the Bluetooth / WIFI module has good performance in near-end communication. Preferably, specific data transmission is performed through the WIFI module. In this example, the near-end display device transmits data to the background MES server through its WIFI module for storage; the 2.4-inch display screen displays the processed data to the user and provides a user interaction interface. Furthermore, the MES server functions include: data acquisition, storage, processing, and display. Preferably, in the case of large data volume and high computing power requirements, the near-end display device transmits the collected data to the MES server, which processes the collected data and feeds back the processing results to the near-end display device or other display devices for display.

[0058] The transformation plan optimization module is used to optimize the configuration of the preliminary transformation plan according to user needs, add the optimized preliminary transformation plan as sample data to the electrical drawing library of the wire harness and cable processing equipment, and recommend it to the user at the same time; the user transforms the equipment based on the received optimized transformation plan;
