Research On The Improvement And Application Of Single Tubular Air-conditioner Evaporator Production Line Based On Lean Thinking

Nowadays,with the rapid development of the internationalization process and the rapid development of the world's technical competence,and with the arrival of the globalization of the market,the individualized demand of customers is becoming more and more high.The products are diversified,the characteristics of small batches are becoming more and more obvious,and the traditional single variety is becoming more and more clear.The weakness of mass and extensive production model is becoming more and more prominent.Lean production is one of the most effective ways to adapt to this kind of production characteristics.The application of lean production theory can not only reduce the cost of enterprises,improve the quality of products,improve the efficiency of production,so as to improve the competitiveness of enterprises,but also is a powerful magic weapon for enterprises to change to intelligent and green manufacturing mode.So that enterprises to achieve economic and social benefits of the double harvest.In order to meet the increasing production requirements,the company introduced and implemented lean production,and the single tubular air conditioner evaporator production line is one of the first pilot production lines.Therefore,how to improve the production line of single tubular air conditioner evaporator based on lean production thinking,so as to effectively improve the product quality,reduce production cost,improve production efficiency,improve the layout of workshop production line and reduce labor intensity.It has important application value and practical significance.First of all,this paper summarizes and analyzes the research status of lean production at home and abroad in terms of connotation,tools,evaluation and application,reviews the origin and development of lean production,and introduces the connotation of lean production.Knowledge system,characteristics and its implementation approach are summarized,and the common theoretical tools and methods of lean production are summarized.Secondly,based on lean production thinking,the value flow analysis of single-flow air-conditioner evaporator production line is carried out by lean production tools,and 6S management is carried out in workshop to improve the processing environment,Kanban management and technological process optimization.The design and optimization of U-type layout and equalization of workshop production line,and finally a lean improvement scheme of production line is put forward.Finally,the concrete implementation steps of improving the production line of single tubular air conditioner evaporator are introduced in detail,the production status of evaporator before and after improvement is compared,and the balance rate of production line,deliveryperiod,Direct benefits such as processing efficiency and indirect benefits of 6S management site improvement are used to evaluate the improved production line benefits.Through the lean improvement of the production line,the better effect is obtained,and the effectiveness and practicability of the Lean improvement program and its activities are explained.
