Análise e aplicação de melhoria da eficiência produtiva na linha de produção em uma indústria de montagem de módulo LCD

Abstract

In recent years, due to the increase of competitiveness among companies, the techniques called productive efficiency have been strongly used, which one use the quality tools to improve results. Efficiency applied to the process means that the product is produced in the most rational way possible. Within the various types of systems in which the concept of efficiency can be applied, one of the most important, is the productive systems. The study of efficiency in the production system is one of the essential aspects for your business to remain active in the market. In some productive efficiency applications, such as in the LCD Module assembly line, they are of interest, as they provide improvements in certain flows of a stable process with less cost and waste. The LCD module is a light emitter with an LCD (Liquid Crystal Display) panel prepared to receive the plates responsible for power supply and signal emissor. Liquid crystal displays (LCDs) are present in the electronic area in various equipment, with emphasis on TVs, calculators, computers and cell phones. With this in mind, the present study aimed to analyze and apply productive efficiency techniques in the process of an LCD Module assembly line, in order to use the available resources more intelligently, spending less and producing more. For this, the methodology was divided into four parts: Analysis of the current situation, Analysis of the Causes, Objective and Goals, Study of the Proposed Solutions and Implementation. In the analysis of the current situation was study the product, the production layout, the time of the production process and the defects of the process. In the analysis of the causes was defined the root causes of the problems or failures are defined. Then the goals and objectives were quantified. Finally, was analyzed the solutions and implementation in the production process. Through this work it was possible to visualize the failures and losses of a productive process and thereby obtain several gains. Among them, the 37% reduction in the defect rate, automation of the process and 18.4% gain in productivity.
