Description

Technical Field

[0001] This invention relates to the field of cable assembly process design technology, specifically to an intelligent cable process design method and system for complex electronic devices. Background Technology

[0002] In the field of complex electronic equipment, cable assemblies are a crucial means of energy and signal transmission. In cable process design, due to differences in production organization methods among companies, the level of detail in cable process documents varies. There are two main approaches: The first is to establish a typical cable product process template library. Each time a task comes in, the template process is referenced, and then a few parameters are adjusted according to the specific cable product to generate a process document. The main problem with this approach is that the template-based process document lacks sufficient guidance for operators, and it is often used in companies with high worker skill levels. The second approach involves cable process engineers creating a detailed, illustrated design for each cable assembly, generating an illustrated SOP (Standard Operating Procedure) document. This approach describes each action with pictures, providing strong guidance, but it demands a high level of expertise from process engineers who need a clear understanding of the detailed manufacturing process for each cable product. This approach is typically used in companies with lower worker skill levels. Both approaches, whether requiring highly skilled or process engineers, involve a significant amount of repetitive work and a waste of human resources.

[0003] The patents “CN114742983A Method and Device for Creating Flexible Cable Features Based on Annotation Dimensions” and “CN114925495A Method, Device, Equipment and Medium for Designing Flexible Cable Assemblies” have proposed a knowledge-based intelligent design tool for cable assemblies. By establishing a library of commonly used cable knowledge rules and models, and through intelligent algorithms, cable drawings are automatically generated, solving the workload problem in auxiliary material selection and drawing generation in cable design, and greatly reducing the investment of human resources in cable product design.

[0004] The patent "CN111985797A Cable Process Flow Card Generation Method, Device, and Computer-Readable Storage Medium" proposes to run a cable process flow card generation system by running a preset file, obtaining sales orders, and automatically generating the process flow card corresponding to the target cable through a cable process generation system. Since the information contained in the cable itself is not complex, its implementation path is mainly based on parameterization, using cable length, identification, and other information as variables, and automatically generating the card by reading order information. This differs from the technical path of cable assembly process design. Cable assemblies include components such as identification, connectors, cables, and sheaths. It primarily involves establishing a cable assembly process knowledge base, which has more complex matching relationships and cable process calculation logic, making it unsuitable for intelligent design of cable assembly processes.

[0005] To reduce low-level repetitive work in cable process design activities, improve the efficiency of cable process design, and enhance the guidance of cable product process documents, it is necessary to study intelligent design methods for cable product processes. Summary of the Invention

[0006] To overcome the shortcomings of existing technologies, this invention provides an intelligent design method and system for cable processes in complex electronic devices, which solves problems such as excessive low-level repetitive work, low efficiency in cable process design, and poor guidance in cable product process documents.

[0007] The technical solution adopted by the present invention to solve the above problems is:

[0008] A smart design method for cable processes in complex electronic devices includes the following steps:

[0009] S1 automatically analyzes the material type of cable products and obtains the assembly process knowledge required for cable assembly.

[0010] S2, Match the cable process knowledge base and component assembly process method base to find the assembly process method for the cable product;

[0011] S3 automatically generates SOP standard operating procedures or two-dimensional process specification cards based on design documents;

[0012] S4, and automatically set time quotas according to cable product type;

[0013] S5 outputs the configured process documents and process data for the cable product.

[0014] As a preferred technical solution, in step S1, the cable assembly consists of conductors, electrical components, and a sheath; wherein, the assembly process knowledge required for conductor assembly includes conductor weight, conductor length, conductor specifications, incoming direction, and outgoing direction information; the assembly process knowledge required for electrical component assembly includes manufacturer, specifications, location, pin definition, and environmental adaptability parameter information; the assembly process knowledge required for sheath assembly includes manufacturer, specifications, length, and weight parameter information.

[0015] As a preferred technical solution, in step S2, the cable process knowledge base includes process knowledge model definitions, a general assembly process method library, and a matching mapping library for process knowledge models.

[0016] As a preferred technical solution, in step S2, the component assembly process method library includes a standard operating requirement library, a dedicated assembly process method library, and a general assembly process parameter library.

[0017] As a preferred technical solution, in step S3, the input design documents include two types: the first type is a two-dimensional drawing and a list of cable assemblies, wherein the two-dimensional drawing of the cable assembly is in dwg format and the list of cables is in EXCEL format; the second type is a three-dimensional model of the cable assembly.

[0018] As a preferred technical solution, the automatic generation of process documents in step S3 is as follows:

[0019] S31 performs structured parsing on the DWG format file. Based on the material information in the bill of materials, it automatically extracts the material location and length information of the cable assembly from the DWG drawing and parses it into structured data.

[0020] S32, by analyzing the structured data, identifies the material characteristics, quantity, topological relationship, and cable type of the cable assembly, and automatically generates the process flow of the cable assembly.

[0021] S33: Based on the determined standard steps and mapping the cable and electrical component process standard knowledge base, match the detailed operation requirements of each process of this cable assembly, and generate process documents according to the given process specification card template or SOP format template. Among them, the SOP format process documents are only for input files that are three-dimensional models of cable assemblies.

[0022] As a preferred technical solution, in step S32, the process composition and sequence of the RF cable assembly are: preparation → RF cable assembly → inspection → packaging, or preparation → RF cable assembly → potting → inspection → packaging; the process composition and sequence of the low-frequency cable assembly are: preparation → low-frequency cable assembly → inspection → packaging, or preparation → low-frequency cable assembly → potting → inspection → packaging; wherein, the preparation process includes detailed data on material completeness, the RF cable assembly process and the low-frequency cable assembly process include detailed assembly operation steps of the cable assembly, the inspection process includes the inspection requirements for the cable assembly products, the potting process includes the potting operation performed according to the sealing conditions required by the technical requirements of each cable assembly, and the packaging process includes the packaging requirements for the cable assembly products.

[0023] As a preferred technical solution, in step S4, when the work time is automatically set, the formula for calculating the work time of the process is:

[0024] Tgx = ∑Tgb × n / 60 + Tzj;

[0025] Where Tgx represents the process time, Tgb represents the step time, Tzj represents the completion time, and n represents the number of steps.

[0026] As a preferred technical solution, in step S4, the calculation of the work step quota parameters is divided into three categories: the current work step operation time and the quantity of material objects composed of cable assemblies are calculated linearly; the current work step operation time is calculated as a fixed value; and the current operation time is calculated as a non-linear time based on special conditions. The time calculation parameters are classified and summarized in this way, and a parameter library is established to establish the mapping relationship between the work step and the calculation parameters.

[0027] A cable process intelligent design system for complex electronic devices is provided to implement the aforementioned cable process intelligent design method for complex electronic devices. The system includes a process intelligent design module, and further includes a cable process knowledge base, a component assembly process method library, a time quota module, and a data output module, all connected to the process intelligent design module. The process intelligent design module executes steps S1 to S3, the time quota module executes step S4, and the data output module executes step S5.

[0028] Compared with the prior art, the present invention has the following advantages:

[0029] This invention establishes a cable assembly process knowledge rule base and an electrical component attribute base. After inputting cable product design data, it automatically parses the input file, matches it with knowledge from the rule base and electrical component attribute base, creates typical process flows, and assigns process content values ​​according to the input cable type, automatically generating two-dimensional process documents or three-dimensional SOP process documents. This design method and system can improve cable process design efficiency by at least three times, significantly reduce repetitive work in process design, and improve the consistency and guidance of process documents.

[0035] The present invention will be further described in detail below with reference to the embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0036] Example 1

[0037] like Figures 1 to 5 As shown, this invention proposes an intelligent cable process design method for complex electronic devices based on existing intelligent cable design tools, which reduces repetitive work for process engineers during the cable product process design and improves the guidance of process documents.

[0038] The invention is as follows:

[0039] 1. The intelligent design method and system for cable product processes includes a cable process knowledge base, a component assembly process method library, an intelligent process design module, a time quota module, and a data output module, such as... Figure 1 As shown. The cable process knowledge base mainly refers to cable process knowledge, including process knowledge definitions, assembly process methods, and a matching mapping relationship library for cables, connectors, and auxiliary materials; the component assembly process method library mainly refers to a component standard operation requirement library, a dedicated assembly process method library, and a general assembly process parameter library; the intelligent process design module includes a knowledge- and data-driven SOP automated design module and a knowledge- and data-driven two-dimensional procedure card automated design module; the time quota module mainly includes a low-frequency cable time calculation model and a radio frequency cable time calculation model; the data output module mainly includes a process design data output module and two functions: process document display and browsing.

[0040] The intelligent process design module is the core module of the system, which realizes the automatic design of cable processes. The method specifically includes: automatically analyzing the material type of the cable products imported into the system, analyzing and obtaining the assembly process knowledge required for cable assembly, matching the assembly process method of the cable product from the cable process knowledge base and the component assembly process method library, automatically generating SOP standard operation documents or two-dimensional process specification cards as needed, automatically quoting working hours according to the cable product type, and finally outputting the configured process documents and process data of the cable product.

[0041] 2. Due to the diverse types of materials used in cable assembly components, and the differences in models and parameters among manufacturers for the same type, modeling cable assembly process knowledge is crucial and forms the basis of intelligent process design. This invention proposes a cable assembly knowledge definition method based on ontology modeling, defining a structured data model of component materials and constructing the ontology concept relationships for cable assembly design. For example... Figure 2As shown. Cable assemblies consist of conductors, electrical components, and sheaths. The conductors include information such as conductor weight, length, specifications, direction of arrival, and destination. Electrical components include connectors, tail accessories, coaxial contacts, adapters, and protective covers, each with parameters such as manufacturer, specifications, location, pin definitions, and environmental adaptability. Sheaths include braided sheaths, heat shrink tubing, anti-surge sheaths, marking sheaths, and transparent sheaths, each with parameters such as manufacturer, specifications, length, and weight.

[0042] 3. Figure 3 This is a flowchart of a knowledge-based intelligent cable process design tool. The input design documents fall into two categories: the first type is 2D component drawings and parts lists, using standard AutoCAD-generated DWG format drawings and Excel formats for parts lists; the second type is 3D cable assembly models. The automatic generation steps for process documents are as follows:

[0043] First, the DWG format file is parsed in a structured manner. Based on the material information in the bill of materials, the material location, length, and other information are automatically extracted from the DWG drawing and parsed into structured data.

[0044] Second, by analyzing the structured data, material characteristics, quantities, topological relationships, and cable types are identified, automatically generating the process flow for cable assemblies. The typical cable product process route is as follows: For RF cable assemblies, the process composition and sequence are: Preparation → RF cable assembly → Inspection → Packaging, or Preparation → RF cable assembly → Potting → Inspection → Packaging; For low-frequency cable assemblies, the process composition and sequence are: Preparation → Low-frequency cable assembly → Inspection → Packaging, or Preparation → Low-frequency cable assembly → Potting → Inspection → Packaging. The preparation process mainly includes detailed data on material completeness; the RF / low-frequency cable assembly process mainly includes detailed assembly operation steps; the inspection process mainly covers the component product inspection requirements; the potting process mainly involves potting operations performed according to the sealing conditions required by the technical requirements of each component; and the packaging process mainly covers the component product packaging requirements.

[0045] Third, based on the required standard steps such as material cutting, welding, crimping, sheathing, and packaging, and mapping to the cable and electrical component process standard knowledge base, the detailed operation requirements of each process of this cable assembly are matched, such as welding operation, crimping operation, wire harness arrangement operation, etc. The process documents are generated according to the given process specification card template / SOP format template. The SOP format process documents are only for cable assemblies whose input file is a three-dimensional model.

[0046] 4. Figure 4This invention relates to a SOP (Standard Operating Procedure) template for intelligent cable manufacturing processes. It's a format for displaying SOPs generated through intelligent process design, primarily including a process structure tree, version management, step operation content, and a 3D model display area in the left window. By clicking on a process or step in the process structure tree in the left window, the specific operation content for that process or step can be viewed in the step operation content window, along with the required 3D model.

[0047] 5. Based on the actual business of labor time quota, the process time quota consists of two parts: the processing time (manual time) of the process step and the quasi-completion time. Tgb represents the process step time (manual time), Tzj represents the quasi-completion time, and n represents the number of process steps. These three parameters are the basic data for the composition of process time Tgx. The calculation method of process time Tgx is: Tgx=∑Tgb×n / 60+Tzj.

[0048] The calculation of work step quota parameters is divided into three categories: 1) The current work step operation time and material quantity are calculated linearly; 2) The current work step operation time is calculated as a fixed value; 3) The current operation time is calculated non-linearly based on special conditions. The work time calculation parameters are classified and summarized in this way to establish a parameter library and establish a mapping relationship between work steps and calculation parameters.

[0049] This invention establishes a cable assembly process knowledge rule base and an electrical component attribute base. After inputting cable product design data, it automatically parses the input file, matches it with knowledge from the rule base and electrical component attribute base, creates typical process flows, and assigns process content values ​​according to the input cable type, automatically generating two-dimensional process documents or three-dimensional SOP process documents. This design method and system can improve cable process design efficiency by at least three times, significantly reduce repetitive work in process design, and improve the consistency and guidance of process documents.

[0050] Example 2

[0051] like Figures 1 to 5 As shown, as a further optimization of Embodiment 1, this embodiment also includes the following technical features based on Embodiment 1:

[0052] According to the method of this invention, cable assembly DWG format drawings and material composition details, or cable 3D design models, are loaded. The input data is automatically parsed into structured data, and then matched against the materials in the cable assembly details to identify the process components of the cable product. Next, corresponding assembly process parameters and assembly requirements are matched against the cable knowledge base and electrical component model library, and time quotas are set for each process. A complete cable product process document is automatically generated, including a two-dimensional process card or a three-dimensional SOP document, which can be read through a process document viewing window. Figure 5As shown in the diagram, the left side displays the reconstructed tree structure, the upper-middle area is the model display area (including 2D drawings or 3D models), the lower-middle area is the automatically generated process specification area (including time information), and the rightmost area displays the product material composition details. This intelligent cable process design method can significantly improve the efficiency of cable process document design and enhance the guidance of process documents.

[0053] As described above, the present invention can be implemented well.

[0054] All features disclosed in all embodiments of this specification, or steps in all methods or processes implied in the disclosure, may be combined and / or extended or replaced in any way, except for mutually exclusive features and / or steps.

[0055] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Based on the technical essence of the present invention, any simple modifications, equivalent substitutions, and improvements made to the above embodiments within the spirit and principles of the present invention shall still fall within the protection scope of the present invention.
