APPARATUS FOR DRYING OPTICAL FILM

摘要

The present invention relates to an apparatus for drying an optical film, drying an optical film comprising particles therein. The apparatus for drying an optical film comprises a dry chamber in which the optical film enters; a stage located on the lower surface of the optical film, including a mass change measurement device, and vertically moved inside the dry chamber; a hot air nozzle applying convection heat to the optical film by supplying hot air to the optical film; and a camera taking a photo of the structure of the particles and the surface of the optical film. According to an embodiment of the present invention, the apparatus can analyze dryness rate of the optical film by real-time measurement of mass change during a drying process of the optical film, can analyze changes in the structure of the particles included therein and changes in the surface structure of the film by the camera, and further can reduce the dry room size by vertical movement of the stage moving the optical film.
