Flat Panel Display Deflection Analysis Considering Lift Force in Non-Contact Flat Panel Display Conveyer System

Flat Panel Display(FPD) is widely used a video display terminals to consumer products of LCD and PDP. The contamination and damage were affected by using the previous contact conveyor's method. In this paper, it analyzes the FPD deflection to develop the non-contact FPD transfer process using lift force. Each conveyor's equipment is called a horizontal conveyor, vertical conveyor and robot pick-up equipment. As result of an analysis of FPD panel's deflection, a robot pick-up equipment has performed according to under the present conditions like panel's weight and loaded glass to move FPD panel from one place to other places properly. Results of the analysis showed 0.474 mm, 0.424 mm and 1.237 mm. Those values are lower than a predicted optimum values : 2 mm for both horizontal and vertical conveyers; 5 mm for robot pick-up equipment. Therefore, those results verify each equipment have safety and reliability.
