Problems solved by technology

However, in related technologies, photocuring generally uses ultraviolet lamps to irradiate the liquid crystal layer directly. The uneven illumination of various parts of the surface of the liquid crystal layer leads to uneven curing, unevenness after curing, warping, etc., and poor curing quality. high
For example, a liquid crystal film is prepared by using chiral polymer curing liquid crystal technology. Although this film has a strong brightening effect, due to the use of a simple ultraviolet lamp, the intensity of ultraviolet light irradiated on the film is not uniform, thus affecting the liquid crystal. Film properties
[0003] Secondly, in addition to the application of thin-film materials in small-size fields such as semiconductors, they are also widely used in the field of display devices. The size of the display device film is relatively large. Taking a 32-inch display as an example, its size is 750mm×450mm, while the existing UV curing Irradiation techniques are difficult to cure large area thin film materials

Abstract

The invention provides an ultraviolet curing irradiation device comprising a light guide plate and at least one ultraviolet light source, wherein a workpiece to be irradiated is arranged on the emergent side of the light guide plate; the at least one ultraviolet light source is arranged outside the light guide plate and on the side vertical to the emergent surface of the light guide plate; and lattice points on the light guide plate reflects ultraviolet rays emitted by the ultraviolet light source to the workpiece to be irradiated. The invention also provides an ultraviolet curing irradiation system and an ultraviolet curing irradiation method. According to the technical scheme of the invention, uniform curing of a film can be realized, the film is flat and does not warp after being cured, and the curing quality is improved.

Description

technical field [0001] The present invention relates to the field of curing technology, in particular to an ultraviolet curing irradiation device, an ultraviolet curing irradiation system and an ultraviolet curing irradiation method. Background technique [0002] At present, the curing methods of the liquid crystal film include heat curing, light curing and the like. Wherein, photocuring is to irradiate the liquid crystal layer with ultraviolet rays, so that the liquid crystal layer is cured to form a liquid crystal film. However, in related technologies, photocuring generally uses ultraviolet lamps to irradiate the liquid crystal layer directly. The uneven illumination of various parts of the surface of the liquid crystal layer leads to uneven curing, unevenness after curing, warping, etc., and poor curing quality. high. For example, a liquid crystal film is prepared by using chiral polymer curing liquid crystal technology. Although this film has a strong brightening effe...
