Abstract
The utility model discloses an ultraviolet curing device which comprises an ultraviolet curing chamber formed by four side walls and a top wall. One end of the ultraviolet curing chamber is opposite to the top wall and is provided with an opening to form a curing window used for ultraviolet rays to penetrate out. A plurality of ultraviolet ray emitting units are arranged in the ultraviolet curing chamber, and the curing window is provided with a mask plate. The mask plate is provided with a protective reflection layer, and an ultraviolet ray reflection device which reflects the ultraviolet rays towards the curing window is arranged between the protective reflection layer and the top wall. When ultraviolet curing is carried out for a liquid crystal display panel, the ultraviolet ray emitting units emit the ultraviolet rays towards the curing window. At the moment, low-efficient lights in the ultraviolet rays are reflected towards the curing window by a reflection layer between the protective reflection layer of the mask plate and the top wall, wherein the low-efficient lights in the ultraviolet rays shine on the protective reflection layer of the mask plate and are reflected back to the ultraviolet curing chamber. Accordingly, the ultraviolet rays are reutilized, and utilization rate of the ultraviolet rays emitted by the ultraviolet ray emitting units is improved.
