Research On Balance Improvement Of Mobile Phone Assembly Line Of A Company Based On Lean Production

For assembly manufacturing enterprises,the improvement of production line balance rate is the subject of continuous improvement.At present,many assembly manufacturing enterprises still adopt the traditional one-character long-line production mode,and its production line balance rate is difficult to achieve a greater breakthrough.Production line balance used to be a simple problem,but it was a systematic problem under the new order mode with short delivery time and many varieties.As a well-known brand of mobile phones,the internal manufacturing management team has tried many times to improve the balance of production lines,but always with half the effort.In this paper,according to the current situation of assembly rollers in A company,a solution of production line balancing system based on new order mode with short delivery time and many varieties is proposed to break through the predicament that manufacturing capacity is difficult to improve.First of all,analyze the A company's external business environment,industry characteristics,order structure,internal processes,and then comparing the peer benchmarking enterprises put forward A company needs to solve the production line balancing problems.Finally,the typical product R807 has been improved many times by using the Lean Tools such as rhythm setting,pipeline layout setting,bottleneck improvement and production line balancing technology.Finally,the opening time of R807 has been reduced,the inventory of in-process products has been reduced,the total standard time has been reduced,and the production efficiency and manufacturing capacity have been greatly improved.Finally,on the basis of the theoretical research of lean production and production line balance combined with the practical application of A company,this paper extracts three measures worth promoting in the process of improving production line balance in mobile phone assembly workshop: U-type flexible production line mode with fewer people as the main body,and automatic equipment introduction with action unit as the object,in order to reduce the modular improvement of the total standard time.The practice summary should deserve a lot of peer reference,enhance the competitiveness of the enterprise.
