Simultaneous ultraviolet curing device for product of double-layer UV gel structure

Abstract

The invention discloses a simultaneous ultraviolet curing device for a product of a double-layer UV gel structure. The simultaneous ultraviolet curing device comprises a first parallel light source mechanism for curing a first UV gel layer, a second parallel light source mechanism for curing a second UV gel layer, and a plane lens which is arranged at 45 degrees at the intersection of light rays of the first parallel light source mechanism and light rays of the second parallel light source mechanism. The first parallel light source mechanism is arranged over the first UV gel layer and the second UV gel layer in the vertical direction. The second parallel light source is arranged obliquely above the first UV gel layer and the second UV gel layer in the horizontal direction. Compared with the prior art, the simultaneous ultraviolet curing device is novel and unique in structure and can conduct ultraviolet curing on double-layer UV gel or UV printing ink simultaneously, and the machining efficiency is improved by one time at least; and in addition, the double UV gel or the UV printing ink is evenly cured, the defective rate is greatly decreased, light energy losses are reduced, the application range is wide, and the economic benefits are high.

Description

technical field [0001] The invention relates to the technical field of ultraviolet curing equipment, in particular to a simultaneous ultraviolet curing device for products with a double-layer UV glue structure used in the processing and manufacturing of display screens, instruments, printing, packaging and the like. Background technique [0002] UV light curing technology has long been widely used in the curing of products containing UV adhesives or UV inks in industries such as display screens, electronic medical care, instruments, building materials, furniture, home appliances, automobiles, printing, and packaging. However, in the face of the high-precision and high-efficiency processing requirements of modern products, the original UV light curing equipment technology has gradually revealed its shortcomings: First, the UV light source of the original UV light curing equipment mostly uses a single point light source Or a surface light source formed by an array of multi-poi...

Problems solved by technology

However, in the face of the high-precision and high-efficiency processing requirements of modern products, the original UV light curing equipment technology has gradually revealed its shortcomings: First, the UV light source of the original UV light curing equipment mostly uses a single point light source Or a surface light source formed by an array of multi-point light sources, but the light emitted by this type of light source is scattered light, which cannot form uniform and uniform light spots on the irradiation surface, resulting in different UV curing agents at different irradiation points due to different energy received. The curing time varies, which may easily cause product deformation defects and affect production efficiency; secondly, the existing UV light curing equipment can only use a single wavelength of UV light for curing processing at the same time, and in some cases containing multi-layer UV glue Or in the UV light curing process of ink products, it is impossible to complete the curing of multi-layer UV glue or ink products at the same time, especially in the process of touch screen processing, it is necessary to bond multiple layers of materials into a whole, if according to the original processing technology , each adhesive layer needs to be processed by UV light curing once, which increases the processing cost and time cost
