Problems solved by technology

[0003] In the existing UVLED curing equipment, the luminous efficiency of UVC lamp beads is very limited. Taking LG's 278nm UVLED model LEUVA66H70HF00 as an example, its nominal illuminance is 70mw / cm2, and 40 LEDs can be arranged in an area of ​​50mm*30mm. LED, the illuminance is not enough to reach 170mw / cm2, but the cost is extremely high, and the efficiency is low

Abstract

The invention relates to a UV curing device and a curing process thereof. The UV curing device comprises a mounting frame, a conveyor belt arranged on the mounting frame, and a plurality of groups ofUVLED light sources arranged on the upper side of the conveyor belt, wherein the upper side of the conveyor belt is also provided with a plurality of groups of UVC light sources; the UVC light sourcesare positioned at the rear side of the UVLED light sources in the moving direction of the conveyor belt; and the UVLED light sources are arranged at the feeding end of the conveyor belt, and the UVClight sources are arranged at the discharging end of the conveyor belt. The device has the advantages of high working efficiency, low cost, high illuminance per unit area and good curing effect.

Description

technical field [0001] The invention relates to LED packaging equipment, more specifically to a UV curing equipment and a curing process thereof. Background technique [0002] At present, in UVLED curing applications, based on the cost of use and the needs of the pre-cured product, the wavelength selection range of UVLED is between 365-405nm. For some products in the application process of UVLED curing, especially in the application of glue curing, when the product is irradiated by the UVLED light source, the surface to be cured will have poor surface dryness and sticky hands. The reason for this phenomenon is that the glue lacks short-wave ultraviolet rays, especially UVC (wavelength range 180nm-280nm) radiation, which leads to incomplete chemical reactions during the monomer polymerization and crosslinking reaction. As we all know, during the UV curing process, the cured substance (pre-cured product) will generate free radicals after UV irradiation, and the free radicals ...
