| dc.description.abstract | The projector industry in Taiwan, due to the small amount of diversity, but must meet the market demand for different types of aircraft. In such a diversified market structure and types of printed circuit board assembly projector and becomes very much, relative host board assembly test has become more complex. Therefore, the function test of the projector of the printed circuit board assembly production process is smooth, but also related to the overall production and operation cost and efficiency, is one of the projector product manufacturing of key elements. Therefore, the further research and improvement of assembly printed circuit board production line will be helpful to the survival and development of Taiwan projector industry in the severe market competition environment.
With the application of the progress of science and technology and lean production ideas, printed circuit board assembly production line test mode also continued evolution to improve. On software, from the early the projection screen is projected to artificial interpretation of the mode of production, we hope that this research, and gradually by the computer system to replace. In terms of hardware, from the early use projector finished machine way production test, have gradually adopted for album fixture modular test equipment to replace.
In this study, but by the case company over the years in speculative shadow machine printed circuit board assembly production mode and constantly improve the process, to explore the improvement of test equipment is mainboard of the projector product assembly industry is essential, how to use application of automation to achieve the quality detection more efficient and more accurate. In order to promote the results applied to the projector industry, the conclusions are as follows:
1. projector assembly printed circuit board function testing automation, the average test time can be reduced from 226 seconds to 55 seconds, to enhance the efficiency of 76%, the product delivery period is shortened from 7 days to 4 days, more market competitiveness.
2. using computer programs to automatically interpret the picture quality, the test manpower decreased from 80 to 52 people, the human reduced by 35%.
3. Input signal source demand multiple sets of equipment, all the staff switched multiple input signal source, research and analysis with software functions, the realization of automatic switching of input signal source, signal source device consists of three sets of demand fell to 1 station to be able to meet. | en_US |
