Specializing in the manufacture of permanent magnet DC motors for automobiles, brushless motors, evaporative fans for automotive air conditioners, condenser fans, radiator radiators, electric power steering systems EPS brushless motors and controls, door electric window regulator assemblies, windshield washers , eddy current retarders for passenger cars, fuel heaters, etc. The company's current annual output of more than 1.5 million sets (sets), products and many well-known brands of cars, mini-cars and light, medium and large passenger cars and other models for the first and second, such as FAW Hainan Mazda, Jinbei sea lion, Chinese car, Nanjing Iveco, Nanjing Fiat, Xiamen Jinlong, Chongqing Changan, Changhe, Liuzhou Wuling, Zhengzhou Yutong, Zhangjiagang Peony, Jiangsu Yueda, Changfeng Cheetah, Huatai Traka, Valeo VALEO and Delphi DELPHI, etc., and to the United States, Sweden, Canada, Japan, South Korea and other countries export in batches.
Problems:
With the application and popularization of software such as CAD and ERP in Jiangsu Superpower, the company has experienced many problems in information security, data management, etc. while improving the design efficiency and the informatization process. How to solve a large number of electronic drawings And the management of data to ensure the accuracy and authority of electronic data has become an urgent task. The problems in enterprise data management are summarized as follows:
Design drawings, document management
Jiangsu Chaoli Company's product structure is complex and simple; there are many orders and deformation products, and the drawings between the same types of products are reused, and involve many majors such as machinery and electronics. At the same time, it involves 2D, 3D and electronic maps. The amount of drawings is large. The traditional CAD software does not have the function of pattern and document management. It relies on the operating system to realize the management of pattern documents. The information query method is simple and cannot be designed by designers. , time, product attributes and other means to effectively query the required information. At the same time, design data and technical documentation are scattered across each designer's computer and cannot be managed uniformly. Resources cannot be shared between departments, resulting in data redundancy.
Safety aspects of designing electronic information such as drawings and documents
Due to the fierce competition in the market, strengthening the confidentiality of design drawings, designs and process documents has always been a key concern of the company. The traditional materials preserved in "paper" are kept by dedicated personnel, while CAD drawings and documents are stored in the form of electronic materials. The degree of sharing is greatly enhanced, and the security of confidential information is greatly threatened. The development of intranet networks and hacking techniques have made this form even more critical, and companies urgently need a secure and flexible security measure.
Technical file change aspect
The electronic documents in the technical documents and the paper media files in the archive department are often not consistent, and the paper media documents in the archive department are not consistent with the documents on the production floor. Due to changes in documents and related materials, and the change process has not been recorded in a timely and effective manner, or the changes have not been completely changed, it is difficult to ensure that the technical documents delivered to the workshop can be promptly changed without missing.
Information integration
A large amount of design data information already existing in various versions of CAD electronic image files cannot be utilized by the subsequent process and production management information system of the enterprise, and needs to be manually input again, resulting in waste of human resources, and may be mistyped, resulting in no information. accurate. Therefore, it is imperative to establish a product data management system to integrate and share information and gradually form a computer information management mechanism.
Product design serialization
Increasing the serialization level of products is an effective means to reduce the number of parts design, shorten the product design cycle, and reduce the cost of products. However, parts designed at different times cannot be fully and effectively utilized. Because there is no effective product design management system, in the process of new product development, it is impossible to quickly and accurately find similar parts from common parts, special parts and borrowed parts, and possibly cause product parts. Repeat the design.
solution:
In response to the above problems, Extech has customized a PLM solution for Jiangsu Superpower to improve design and production efficiency through the standard functions of the Extech PLM system.
Specification design source data
Enterprise management standards are first, because CAD/PLM/ERP involves the management of information, and the preparation of corresponding standards for this is one of the foundations for ensuring long-term stable application of the system. CAD drawings are the source of a large amount of product data. In the work, if there is no specification, there may be more data hidden dangers. For example, the original material is the same material. Due to different names, it will bring numerous troubles to manufacturing and purchasing.
Establish product electronic document and data management system to ensure data security
With the CAD standard and the basic resource library, it is necessary to establish a unified product database, manage product drawings, schedules and related documents, and provide accurate, consistent and complete product technical data for production, procurement, finance and other departments. And establish a complete technical document management system, realize the electronic and complete management of product technical documents, make the product data in effective and orderly management, and provide relevant personnel with convenient tools for querying, browsing, borrowing and outputting reports. The goal is:
(1) Organize the electronic drawings of the designed products that have been designed into a unified, standardized and complete electronic document in accordance with the management requirements of PLM.
(2) The products are managed in an orderly manner according to the type.
(3) Batching the design drawings of the specification into the warehouse management, and automatically constructing the assembly tree.
(4) The designer can directly query the archived design drawings within the scope of permission.
(5) Quick summary output of product reports. (ie product list output)
Manage design changes and manage and control design changes
(1) Manage component change versions and change history.
(2) Manage component change orders.
(3) Change the message quick notification and receipt feedback.
(4) It is convenient to query the existing change information.
Workflow management, standardize technical management, improve data accuracy and technical preparation efficiency
(1) Integrate AutoCAD and MS Office to automatically manage the documents in the design;
(2) define and manage workflow templates;
(3) Online review of workflow process documents.
Business income:
Through the implementation of the Extech PLM project, Jiangsu Chaoli's information management level has been greatly improved, and the information island problem has been effectively solved, realizing the electronic management of map documents, processes and technical data access.
The new product design cycle and manufacturing cycle are shortened. The standardization, completeness and consistency of technical documents have been greatly improved. The recycling rate of information resources is more scientific and intelligent. Reduce the time for technical document retrieval, sending and receiving, and review. In the end, it laid a good foundation for the overall information integration of Jiangsu Chaoli Electric Co., Ltd.
