산업용 잉크젯 프린트 정밀전자저울 특성에 따른 측정값 개선에 관한 실험적 분석 = Experimental analysis of measurement improvement by industrial inkjet-printed precision electronic balances characteristics

국문 초록 (Abstract)

정밀전자저울은 정교하고 민감하여 아주 작은 영향 즉 공기중의 수분이나 정전기, 온도변화, 진동에 의해서도 측정값의 변화를 일으킬 수 있다. 현 실험은 장비에서 가장 많은 영향을 받는 온도 영향성, 공기흐름에 따른 정밀전자저울 측정값 개선에 관한 실험적 분석으로 디스플레이공정에 사용되는 잉크젯 설비의 정밀전자저울, 측정값 불일치 현상에서 실험을 통해 개선안을 찾는데 첫 번째 목적이 있다.
기존의 장비에 설치되는 정밀전자저울은 측정 조건에 맞는 제품 적용과 기구적인 외형의 관점에서 무게를 최소화한 형태에 중점을 두었다면, 현 개발 장비를 통한 실험은 전자저울에 전이되는 온도를 최소화할 수 있는 소재와 구조물 제작에 그 두 번째 목적을 두고 있다.
마지막으로 주변 환경 및 측정 조건에 따른 전자저울 측정 결과를 비교, 분석하여 측정값이 영향을 받는 원인을 찾고 최적의 측정 환경을 조성하는 실험을 하였다.
본 프로젝트 보고서는 이를 통해 잉크젯 개발 장비에서 발생하는 정밀전자저울 관련 불합리 내용을 파악하고 수집한 데이터 분석을 통해 개선한 경험으로 추후 정밀전자저울을 활용한 다른 산업군의 장비 개발에 진출하여 제작 가능하게 하는데 기여할 것이다.

The precision electronic balances is sophisticated and sensitive, and can cause very small effects such as moisture in the air, static electricity, temperature change, and vibration. The current experiment is an experimental analysis of improving the measurement value of the precision electronic scale of the inkjet facility used in the display process, and the first purpose of this experiment is to find improvements through experiments in the temperature effect, which is most affected by equipment, and the precision electronic scale according to air flow.
If the precision electronic balances installed in the existing equipment focuses on the application of the product suitable for the measurement conditions and the minimization of weight in terms of the mechanical appearance, the experiment through the current development equipment aims at creating materials and structures that can minimize the temperature transferred to the electronic balances.
Finally, by comparing and analyzing the electronic balances measurement results according to the surrounding environment and measurement conditions, an experiment was conducted to find the cause of the measurement value being affected and to create an optimal measurement environment.
Through this, this project report will contribute to the development and manufacture of equipment in other industries using precision electronic balances as an experience of identifying irrational content related to precision electronic balances arising from inkjet development equipment and improving them through the analysis of collected data.
