Summary: | The present invention relates to a film transfer device. More specifically, the present invention constantly maintains a tension applied to a transfer film to prevent, in advance, a defect in transfer. According to the present invention, the film transfer device comprises: an unwinding roll where the transfer film is wound; a winding roll where the transfer film unwound from the unwinding roll is wound; a feeding motor rotating the winding roll to transfer the transfer film from the unwinding roll to the winding roll; a transfer table installed between the winding roll and the unwinding roll, and vacuum-adsorbing the transferred transfer film to enable the transfer film to be attached to a substrate mounted on an upper surface; and a tension maintaining motor rotating the winding roll and the unwinding roll in opposite directions to each other to constantly maintain a tension of the transfer film transferred from the unwinding roll to the winding roll.
본 발명은 필름 전사장치에 관한 것으로서, 보다 상세하게는 전사필름에 인가되는 장력을 일정하게 유지시켜 전사불량을 사전에 방지할 수 있는 필름 전사장치에 관한 것이다. 이러한 본 발명에 따른 필름 전사장치는 전사필름이 감겨있는 권출롤; 상기 권출롤에서 풀어지는 전사필름이 감겨지는 권취롤; 상기 권취롤을 회전시켜 전사필름을 권출롤에서 권취롤로 이송시키는 피딩모터; 상기 권출롤과 권취롤 사이에 설치되며, 이송되는 상기 전사필름을 진공흡착하여 상면에 안착되어 있는 기판에 전사필름이 부착되도록 하는 전사테이블; 그리고, 상기 권출롤을 권취롤과 반대방향으로 회전시켜 권출롤에서 권취롤로 이송되는 전사필름의 장력을 일정하게 유지시키는 텐션유지모터를 포함하여 이루어진다. |
