The high-power variable ultraviolet light source curing device comprises a light guide part and a light source module, the light source module comprises a plurality of bases, and UV-LED lamp beads are installed on the bases; the bases in the horizontal row form base sets, a first angle adjusting mechanism is arranged between every two adjacent base sets, and every two adjacent base sets are connected through the corresponding first angle adjusting mechanism; and a second angle adjusting mechanism is arranged between every two adjacent bases in the base set, and every two adjacent bases are connected through the corresponding second angle adjusting mechanism. The angles of a first connecting shaft and a second connecting shaft are adjusted through the first angle adjusting mechanisms and the second angle adjusting mechanisms, the light source module can have three shapes, the three shapes correspond to a straight light gathering plate, a first protruding light gathering plate and a second protruding light gathering plate respectively, and a light source of the light source module can be adjusted to be a point light source, a line light source or an area light source, so that one machine can meet the use requirements of different application scenes.

Description

technical field [0001] The invention relates to the technical field of UV-LED light source curing, more specifically, to a high-power variable ultraviolet light source curing device and a curing method thereof. Background technique [0002] UV curing machine is a mechanical device that emits ultraviolet light of a specific wavelength through a specific lamp bead. Its principle is to irradiate the material to be solidified with ultraviolet light of a specific wavelength, so that the photoinitiator inside the material absorbs photons and becomes free radicals or cations. , thereby initiating the polymerization of polymer materials containing active functional groups into solid substances. Traditional UV curing equipment uses mercury lamps as light sources, but mercury lamps have disadvantages such as fast light decay, short life, high heat generation, and environmental pollution.

AI Technical Summary

Problems solved by technology

Traditional UV curing equipment uses mercury lamps as light sources, but mercury lamps have disadvantages such as fast light decay, short life, high heat generation, and environmental pollution. Now they are being replaced by UV-LED light sources with long life, low energy consumption, and no pollution. UV-LED curing machine has been widely used in electronics, printing, construction and other fields

[0003] At present, UV equipment is single-function curing equipment, that is, one UV equipment can only control one type of light, point light source UV curing equipment can only cure a small area of ​​solid objects, and line light source UV curing equipment can only cure For curing in a narrow linear area, surface light UV curing equipment can be used for large-area curing. If a large-area light source is used to cure a small-area or linear area to be solidified, it will inevitably cause energy waste and shorten the life of UV-LED lamp beads. consume

Therefore, under the current circumstances, the applicability of the same UV curing equipment in different application scenarios is not strong, and the effective utilization rate of UV curing equipment is not high

[0004] Some UV devices have the function of switching surface light sources to line light sources or point light sources. Often, most of the LED lamp beads are simply and roughly turned off, leaving only one or a row of lamp beads for UV curing, which will lead to different life spans of the lamp beads. Some lamp beads are more easily damaged, and it is very troublesome to replace individual lamp beads, but the overall cost of replacement is high, and high-power irradiation cannot be achieved
