BAKING DEVICE FOR LIQUID CRYSTAL ALIGNMENT FILMS

摘要

The present disclosure provides a baking device for liquid crystal alignment films, wherein the baking device includes a heating table with openings and lift pins extending and penetrating through the openings, and the lift pins can move between a retracting position and a stretching position to support a glass substrate coated with alignment films, wherein a blocking member is arranged on the lift pin in a surrounding manner to be tightly engaged thereon, so as to block the air stream flowing toward the glass substrate through the openings when the lift pins are situated in the retracting position. With the provision of the blocking members, the air streams flowing toward the glass substrate coated with alignment films can be resisted in the baking process, which prevents the air streams from affecting heat distribution and temperature distribution.

1. A baking device for liquid crystal alignment films, including a heating table with openings and lift pins, each of which extends through a corresponding opening and thus can move between a retracting position and a stretching position to support a glass substrate coated with alignment films,
wherein a blocking member is arranged on each lift pin in a surrounding manner to be tightly engaged thereon, so as to block the air stream flowing toward the glass substrate through the corresponding opening when said lift pin is situated in the retracting position.
