Novel ultraviolet curing device

Abstract

The invention relates to a novel ultraviolet curing device. The novel ultraviolet curing device comprises an ultraviolet generator, a connection adapter, an optical fiber bundle and a vacuum suction nozzle; the connection adapter comprises a first channel and a second channel which communicate with each other; the vacuum suction nozzle comprises a suction portion and a vacuum cavity communicatingwith the suction portion; a light output portion of the ultraviolet generator is connected with the first channel of the connection adapter; the light input end of the optical fiber bundle is connected with the second channel of the connection adapter; and the light output end of the optical fiber bundle is placed in the vacuum cavity of the vacuum suction nozzle. The ultraviolet curing device issimple in structure, and space is greatly saved; and in the ultraviolet curing process, ultraviolet light beams are free of shielding and small in divergency, and therefore light borne by a glue layeris uniform, the light bearing strength is high, and the process consistency and the quality stability are greatly improved.

Description

technical field [0001] The invention relates to a novel ultraviolet curing device, which belongs to the field of optical device coupling. Background technique [0002] The development direction and trend of optical device lens coupling can be roughly divided into the following stages: 1. Single lens plane coupling curing; 2. Multiple lens plane coupling curing; 3. Multiple lens deep cavity coupling curing 4. Lens size miniaturization. [0003] The traditional coupling curing technology is realized by adopting independent mechanical structures for the vacuum nozzle and the UV generator. However, as the lens coupling density increases, the coupling depth increases, and the lens size becomes smaller and smaller, its technical problems become increasingly prominent. First of all, the traditional mechanical architecture solution has too much upper space due to its large volume, leaving no space for key components such as observation cameras. There is very little light on the len...

[0003] The traditional coupling curing technology is realized by adopting independent mechanical structures for the vacuum nozzle and the UV generator. However, as the lens coupling density increases, the coupling depth increases, and the lens size becomes smaller and smaller, its technical problems become increasingly prominent. First of all, the traditional mechanical architecture solution has too much upper space due to its large volume, leaving no space for key components such as observation cameras. There is very little light on the lens, and the beam diverges, and the distribution in the target area is uneven, so that the adhesive layer receives uneven light, insufficient light intensity, poor process consistency, and poor quality stability
