Abstract
An air-floating thin film bonding apparatus and its air-floating roller is provided. The apparatus is composed of an air-floating rollers, which can blow out airflow at a specific angle to be applied to the base film with three-dimensional obstacles. The positive pressure provided by the airflow can be utilized to fill the gap space caused by the three-dimensional obstacles. Therefore, the base film can bond to the bonding film tightly to overcome the wrinkles and defects caused by the three-dimensional obstacle and the problem of unflatness of the film-bonding can be solved.
Claims10
An air-floating thin film bonding apparatus, comprising:
- at least two feed rollers, used to guide a base film and a bonding film to be bonded together, wherein
- the base film includes a first surface and an opposite second surface, and
- at least two thin-film components with a gap space therebetween are disposed on the second surface;
- a bonding roller, receiving the bonding film guided by one of the feed rollers;
- and
- an air-supplying roller, receiving the base film guided by another of the feed rollers, wherein the air-supplying roller is disposed adjacent and corresponding to the bonding roller to press the bonding film to bond to the first surface of the base film, and includes:
- an outer roller, including a plurality of blowing holes on its outer surface and being rotatable;
- an inner cylinder, disposed in the outer roller and including a plurality of through holes within a predetermined angle range on its outer surface;
- and
- an air source, connected to the inner cylinder to provide an airflow to the inner cylinder, wherein the airflow is guided to the blowing holes of the outer roller via the through holes of the inner cylinder to fill the gap space of the second surface of the base film within the predetermined angle range;
- wherein the predetermined angle range is 20-90 degrees.
An air-supplying roller, adapted for corresponding to a bonding roller to bond a base film to a bonding film, wherein the base film includes a first surface and an opposite second surface, and at least two thin-film components with a gap space therebetween are disposed on the second surface, the air-supplying roller comprising:
- an outer roller, including a plurality of blowing holes on its outer surface and being rotatable;
- an inner cylinder, disposed in the outer roller and including a plurality of through holes within a predetermined angle range on its outer surface;
- and
- an air source, connected to the inner cylinder to provide an airflow to the inner cylinder, wherein the airflow is guided to the blowing holes of the outer roller via the through holes of the inner cylinder to fill the gap space of the second surface of the base film within the predetermined angle range;
- wherein the predetermined angle range is 20-90 degrees.
