Case analysis of integrated application solutions in the electronic industry

with the development of information technology, more and more manufacturing enterprises have also embarked on the ranks of "smart" manufacturing China. In order to achieve better development in the fierce market competition, more and more enterprises use information technology to enhance their competitiveness. Although information technology can not solve the core problems of an enterprise, just as radar can not help you fight in war, it can help the coordinated operations of various legions and quickly coordinate the sea, land and air. In the face of market war, enterprises are in fact the same. Starting from the order, how to cooperate with the R & D, process, production, procurement and other departments to timely share and quickly cooperate with each other is also the key to the success of the enterprise system over the market. Information technology is born for this, and the data and experience of each market battle are retained as a reference for the next battle. "Collaboration" requires a software platform, and "analysis" requires not only a platform, but also a method

in order to quickly respond to the needs of orders, a Research Institute of the electronics department selected the Qingruan Yingtai PLM system as the integrated platform for product life cycle management to realize the management of product R & D and design, process design, process and project, manufacturing plan and process control, quality analysis and control, bar code and customer and supplier information. Through the implementation of the information system, collaborative design can be achieved to shorten the development cycle, improve the design quality The goal of reducing development costs is to solidify and optimize the company's high-quality R & D management system. The following will introduce the Institute's key business solutions for the integrated application of design, process and manufacturing execution based on tiplm

I. integrated application key business

in order to meet the management needs of the Institute's information integration, qingruo Yingtai developed an integrated solution for design, process and manufacturing based on the needs of the Institute, and realized the collaboration and data sharing of the four links of product, design, manufacturing and production from the order in the "collaboration". For the management of enterprise data, our proposal is to take product management as the core and "product" as the source, and then organize "design BOM", "manufacturing BOM", technical documents, process documents, manufacturing resources and other information, so as to realize the integrated management of the Institute from order design data management, process information management, manufacturing control and manufacturing execution

qingruo Yingtai's PLM system can organize data in multiple dimensions, such as by project management or by product. Organizing data by project is to attach R & D data to project tasks. A very important feature of project management is "one-time"; However, there are many kinds of modified products and improved products. How to organize the data of modified products? Some products that are slightly adjusted are new products, but they are not new project categories. According to the characteristics of the Institute, we chose to organize the relevant data of orders by products, so we did not organize the data by items in June this year in the Institute

1. R & D data management and process management

take the "cqfp100f" product shown in the figure as an example. The first part of the product "design BOM management" - "at5.07.1348.00" is the actual product assembly. We adopt the management method of all relevant data. With the part BOM as the center, the product related data is expanded level by level under the "at5.07.1348.00" assembly, and the documents, drawings, change orders, substitutes and other information of the whole design process are hung on the parts, so as to form a complete R & D data tree. Such an organization is convenient for the archiving and tracing of the design process data, "said Chen Yanwen, More importantly, the information associated with the part will be brought to the next product or subsystem along with the borrowing of the part, so as to ensure the completeness and effectiveness of the borrowed part data; In addition, there are variant designs. As long as "at5.07.1349.00" is similarly created, such as "at5.07.1349." For the new product, all the data of "at5.07.1349.00" are quoted. As long as the variant part is slightly replaced, "at5.07.1349." Is a new product, which greatly shortens the deformation design time

in the process of R & D, the design of each product of the enterprise is completed independently by individuals, but the drawings are classified in different processes. In the past, designers had to print out all the drawings and classify them to different personnel for approval. It was very troublesome to find people all over the world. In order to solve the coordination problem of R & D drawing review, qingruo Yingtai adopted "automatic drawing division technology". The first step of the automatic drawing division technology is that when the designer brings the product drawings together into the tiplm system, the system classifies the drawings according to the attribute information on the drawings, such as code, name and so on, and automatically adds the reviewer information corresponding to various drawings to the drawing object; The second step is to integrate the review process of each drawing into a complete process through qingruo Yingtai's modeling tool. All drawings of the product are brought into the system and the process is initiated. According to the information on the drawings, the system transfers different types of drawings to different reviewer nodes for review and signature. After the process is completed, the PLM system automatically files the reviewed drawings into the "design BOM management", thus realizing the "automatic drawing splitting technology", The application of automatic distribution technology greatly saves the time of manual submission for approval and shortens the approval and signing cycle

2. Manufacturing BOM management

when the design core data BOM and drawing approval information pass the approval process, the system will automatically generate a corresponding manufacturing BOM in manufacturing BOM management. The manufacturing BOM is also a part centered organization of data (only it is a manufacturing part). Everyone is familiar with the maintenance of the manufacturing BOM. Yingtai's core management of the manufacturing BOM is the same as that of the design BOM. When maintaining the entire manufacturing BOM, it can associate the supplier information, process card information, assembly card information, specification file information, etc. to the corresponding parts of the manufacturing BOM, So as to form a complete manufacturing BOM data

3. Parametric process management

the current process system can be summarized into two technical routes, one is a CAPP system that stores process information in the form of files, and the other is a database system that stores process information. When many enterprises implement the pdm/plm system, the most important information hung on the manufacturing parts, such as: processing process card, assembly process card, etc. generally, the processing process card, assembly process card, etc. are in the form of card. However, qingruo Yingtai's tiplm system has made a new breakthrough in the application of the enterprise, and the process application mode has been further deepened. In this project, the process information has been standardized through the process procedures of a series of products The three levels of process information parameterization and process parameter optimization realize the standardization of the process, process information parameterization and process parameter optimization, thus realizing the continuous optimization of the process

the first level is "process standardization of series products". That is, according to the product series, the process template rules of series products are created in intime's engineering resources, and the prepared product process document template is automatically archived in the process template of series products. In the future, when making process documents of the same series, technologists can directly create a standard process document from the template and make minor adjustments to complete the preparation of process cards, This can greatly improve the work efficiency of technologists in process planning and the standardization of general process information

the second level is "process information parameterization". The parameterization of process information breaks the traditional idea of process cards. First, the process information cards are changed into process information "objects", as shown in the following figure. The "processing operations" of the processing process cards are hung under the processing process cards in the form of "objects". Each process becomes an object under the processing cards, which is arranged one by one according to the processing sequence, It is completely different from the previous file based process cards. On the operation object, equipment, station, operation name, etc. are selected from the drop-down resource rather than manually added, thus enhancing the standardization and accuracy of the operation content; Secondly, the process information object is parameterized according to the needs of process information management, such as: Ceramic seed, powder particle size, film belt specification, etc. in the incoming material parameters in the figure below, the parameter requirements include: ambient temperature, target thickness casting speed. After the process information is parameterized, the process parameters can be optimized to track and analyze the key process parameters

the third level is "process parameter optimization". During the manufacturing execution of MES, information such as equipment, qualified quantity and process parameters on the station shall be collected, and the process parameters with the highest yield and the best benefit shall be obtained through tracking and analysis. Finally, this group of optimized process parameters shall be fed back to the process template of series products by the product series technologist, so as to optimize the process parameters on the process template, In the future, when the technologists of the same series quote the process template similarly, they can obtain the optimal process parameters, and achieve the goal of continuously improving product quality by continuously optimizing the process parameters

s introduction to main business line management

according to the project needs of the Institute, qingruo Yingtai has expanded the MES function in the tiplm system, aiming to establish an agile planning system and form a closed-loop, accurate and efficient planning system through convenient multi planning strategy comprehensive configuration plan; Establish a rigorous workshop scheduling system, comprehensively consider the process plans of different production stages of each production line in the production workshop, solidify the process flow, collect the production process information and manage the production process; MES also involves many functions. The following schematic diagram illustrates the overall framework and data organization of MES in tiplm. In the following figure, the left side is the main business line of MES, and the right side is the structured product data of tiplm system. In the business process of MES, the structured product data is quickly combined with the sales order. Driven by the sales order approval process, the product BOM data in the sales order details is decomposed (because the product data is structured), and the purchased parts in the product BOM are summarized to the purchaser node, waiting for the purchaser to release the purchase and stock in, At the same time, the self-made parts are summarized to form a production scheduling demand that is summarized to the production scheduling personnel node. The production scheduling personnel track and collect the production process by monthly or quarterly demand and production tasks for the urban production scheduling demand

tiplm-mes of the Institute has been applied in depth. The most prominent function of tiplm-mes of qingruo Yingtai is the cooperative application of MES acquisition function and process template. In the production process, workers collect information about equipment and qualified quantity, and avoid environmental pollution. After several times of sample data collection and analysis, the highest production parameters of qualified products are obtained, and these parameters are fed back to the process template. This is the reason why qingruo Yingtai's process information management should be objectified and the template should be serialized. Through the continuous verification and optimization of the process, the template is fed back to ensure that the future production process data are optimal, so as to provide data accumulation for improving product quality. At the same time, it makes the production progress more transparent and controllable
