[Abstract]:SMT is the most popular technology in electronic assembly industry, because of the complexity and high quality of electronic products. Manufacturing execution of SMT production line has also become the research object of information manufacturing management. By means of information technology, the whole process management of production task of SMT production line is realized. It can realize the lean control of the whole manufacturing execution process, so as to improve the finished product rate of product line and the efficiency of the production line, aiming at the management requirements of SMT production line manufacturing execution process control, quality control and so on. It is required to realize the overall coordinated management of SMT production line business based on digital means. Through the study of manufacturing execution technology and characteristics of SMT production line, this paper aims to solve the problem of production line implementation monitoring ability. The backwardness of material turnover management and the lack of quality control methods provide a practical solution. The main research work of this paper is summarized as follows: 1. Starting from the requirement of lean manufacturing execution of SMT production line. The implementation process monitoring technology of SMT production line is studied. By analyzing the process and state of SMT production line, a process oriented dynamic object fine monitoring mode is proposed. Aiming at the execution monitoring of production line equipment, the real-time monitoring Kanban technology of SMT production line based on real-time data is proposed. This paper solves the tedious problem of material preparation in production preparation process by means of progressive experience library production preparation material screening technology. 2. The logistics turnover coordination technology of SMT production line based on digital identification is studied. Based on the analysis and research on the application of bar code technology and RFID radio frequency technology, the flexible coordination technology of complex material relationship based on bar code and the technology of turnover perception and information push based on radio frequency are proposed. The related problem of material turnover in production line and the problem of efficient flow of products on line are solved respectively. The quality control problem of SMT production line is studied. The characteristics and problems of SMT production line quality testing are analyzed and summarized. The complex correlation technology of multi-platform quality data is put forward, and the complex correlation of multi-link, multi-form execution data and quality data is realized. On this basis, the SMT production line statistical process control technology and SMT defect quality graphical marking technology are studied. For SMT production line quality process control and visual display of quality data provides an effective solution. 4. Based on the specific requirements of the enterprise SMT production line, using ASP.NET. The SMT production line manufacturing execution management system is designed and developed by WinForm NHibernate and other technologies, and it is analyzed by practical engineering examples. The rationality and validity of the technology are verified.
