Abstract
The invention discloses a method and an apparatus for drying and cooling a glass substrate. The method comprises the steps described below. The method delivers the glass substrate cleaned by a cleaner into a baking oven by a first roller device. It dries the glass substrate using an infrared heating plate installed in the baking oven. It delivers the dried glass substrate into a cooling chamber by a second roller device. It cools the dried glass substrate using a cooling plate installed in the cooling chamber. And it delivers the cooled glass substrate onto a platform of an air floating type coater, and coating the glass substrate. This invention also discloses an apparatus corresponding to the method. According to the embodiments of the present invention, it is possible to reduce the number of foreign particles on the glass substrate before coating, and the drying effect is excellent.
