RING SHAPED VIBRATION PREVENTING STRUCTURE OF CANTILEVER TYPE ROLL-TO-ROLL DEVICE

摘要

The present invention relates to a cantilever type roll-to-roll device. The purpose of the present invention is to provide a ring shaped vibration preventing structure of the cantilever type roll-to-roll device capable of absorbing vibration generated when a roll rotates at a high speeds to prevent transmission of the vibrations by installing a ring shaped vibration absorbing pad on a guide holder utilized for coupling the roll and a bearing to a cantilever beam of the cantilever type roll-to-roll device; preventing damage to the roll and the rupture of the roll by preventing a resonance phenomenon that the vibration generated in the roll is transmitted to the cantilever beam; and improving workability by stably rotating at super precision when processing a super precise film. In the cantilever type roll-to-roll device composed of the roll formed into a shaft type for precise rotation having one end from which a coupling unit with a decreased diameter is integrally extended, the ring-shaped bearing to couple the coupling unit of the roll, the flange-shaped guide holder having a coupling piece wherein a coupling groove to couple and fixate the bearing, and the cantilever beam on which the guide holder is joined and fixated; the present invention is characterized by including a rig shaped guide groove on the outer circumference of the coupling piece of the guide holder in the circumferential direction, and the ring shaped vibration absorbing pad to be inserted and joined to the guide groove.;COPYRIGHT KIPO 2015
