A Study on Rotary Type Embossing Process System for Spacer Tape Production

Abstract

Recently, component materials for display are being developed into higher value-added industries which can strengthen national industrial competitiveness. However, a system for production of component materials for display is nearly depending on import, and its development level is inadequate. For this reason, localization of the embossing treatment system for production of the spacer tape and system improvement for increasing of productivity are needed. Therefore, in this paper, we propose rotary type embossing process system for spacer tape production for localization of system and increasing productivity. The system consists of unwinding, forming, cleaning, winding and testing parts. The mold of forming part is designed to rotary type. And we designed each part and made a prototype to test its performance. We measured embossing shapes, diameter and distance between each embossing and opposite embossing using three coordinate measuring machine. Also, we measured impurity level and the number of impurity particles of sample through the testing and cleaning part. Additionally, the productivity of spacer tape produced by the prototype is measured.
