The UV-LED curing device with the adjustable point, line and area light sources comprises a platform, an adjusting mechanism and bases distributed in a matrix, wherein the rear sides of the bases are connected with the platform through the adjusting mechanism; the front sides of the bases are provided with UV-LED lamp beads and light gathering cups for gathering light emitted by the UV-LED lamp beads into parallel light; the bases in the transverse row form a base set; the UV-LED lamp beads in the base set form a light source set; and the adjusting mechanism is used for controlling the base set to rotate towards the transverse central axis of a matrix and further used for controlling the bases in the base set to rotate towards the longitudinal central axis of the matrix. According to the UV-LED curing device with the adjustable point, line and area light sources provided by the invention, a light source can be adjusted to be a point, line or surface light source, so that one machine can meet the use requirements of different application scenes, and the applicability and the utilization rate of the equipment are improved; and multiple UV-LED line light sources are converged on the same axis, multiple UV-LED point light sources are converged on the same point, the light source irradiation intensity at the convergence position is high, and the requirement of a user for high-power light source irradiation can be met.

Description

technical field [0001] The present invention relates to the technical field of UV-LED curing, and more specifically relates to a UV-LED curing device with adjustable point, line and surface light sources. 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
