Improve Research Of The Application Of Value Stream Mapping In Desay’s SMT Line

With the increasing development of our society, people have personalized products growing demand, which spawned the increasingly fierce market competition, but also people’s material needs and taste more and more, more and more high, the product only to diversify, high-grade, high-quality, personalized direction, in order to better meet the needs of the market and the people, in order to meet the rapid development of enterprises, and these companies will be manufacturing technology and production management proposed a more stringent requirement. The value of the flow chart as our proven tool for us to discover and eliminate the production of waste, to grasp the production flexibility provides a good basis for us to shorten product delivery cycles improve customer satisfaction, compression production management costs, improve product quality brought endless potential. And this is the new era of enterprise pointed out the direction, In order to meet the new situation and deal with the fierce competition has brought new opportunities, which is widely used in manufacturing enterprises. This article will Desay’s Value Stream design and application research, the main work and the results are as follows.(1) This article selected background are analyzed and introduced, and the content of the graduate students for paper and structure are introduced.(2) with the introduction of the lean production related theoretical basis, lean value stream mapping and related terms are introduced, the relevant value stream mapping is given by illustrations.(3) Desay’s company profile, industry situation and management status are introduced, and the company "Surface Mounted Technology in mould production line" of the present situation is analyzed.(4) According to Desay’s company SMT production line production status, using the theory of value stream mapping, analysis of production data collection, a comprehensive map of SMT production line of various internal and external action transformation, the optimization of the flow chart for internal and external action, and use tools such as fishbone diagram, causal matrix analysis of the current flow chart on the waste to improve.(5) Through to the SMT production line flow chart in detail, namely the action time optimization, the layout of the serial parallel transition, both inside and outside, the flow of information transmission, chart analysis, optimized that conforms to the SMT production line state diagram in the future. For the variety and small batch products of quick die change to create a good condition of enterprise competition.(6) In order to better guide the subsequent implementation of lean production, at the same time guarantee the improvement of the lean production implementation after results, formulate the implementation of the value stream mapping and safeguard measures.
