Researchon Manufacturing Process Monitorin And Quality Control Technologieswith Lean Production For Mixed-model Assembly Line

As an advanced manufacturing and management mode, lean production is highly concerned by academia and industry. With continuous improvementas its target, much more attention is paid for the production process-oriented management, and also for the personnel management. Lean production is people-orientedandemphasis on the fine management of the production process. With the upgrading of enterprise information level, combining lean production concepts and information technology, Using information technology to support the implementation of fine management and monitoring of production process.To promote the implementation of lean production has important practical significance.At present, the assembly manufacturing enterprises in our country is mainly in the way of manual assembly and mechanical assembly isauxiliary. The level of automation and information is low. Could not achieve the effective control of the assembly process. The assembly quality and stability of the product depends largely on the level and experience of the assembly workers. Lack effective means of quality control in assembly process. So, need to solve the problem of real-time data acquisition of production process and realize the visualization of field management.The technology of RFID can effectively track and monitor the production factors needed for production as required materials, equipment, personnel, WIP etc. Collect production information in a timely manner. Combining with the production management system, effectively improve the production organization, shorten production cycle, reduce WIP(work in process), reduce the production lead time,and improve product quality and competitiveness. Respond to changes in the market and meet the needs of manufacturing enterprises for production management and quality control.The mixed-model assembly line is the object of studying in the paper. Analysis the requirement of real-time data for production process monitoring and quality control in lean production.Compare the advantages and disadvantages of RFID technology and bar code technology and Design and establish a set of RFID and bar code based on the combination of the object identification and information collection program and RFID tag data model. Support the realization of visualization in production process.The mixed model assembly line has the characteristics of multi variety and small batch production, and a solution for the production process visualization of mixed flow production line is proposed. Study on the technical methods of production monitoring and quality control. And design the system of production monitoring and quality control based on RFID.
