Description

Technical Field

[0001] The invention relates to the technical field of irradiation lamp adjustment, and in particular to a irradiation intensity multi-point automatic leveling system and a leveling method. Background Art

[0002] UV curing technology, namely ultraviolet radiation curing technology, is widely used in the curing of materials such as coatings (paints), inks, adhesives (glue), etc. UV light is irradiated to convert the material from liquid to solid. In order to improve the curing efficiency and enhance the curing effect, the existing UV curing technology has begun to shift from a planar single-point curing method to a planar multi-point curing method, that is, multiple ultraviolet light sources are simultaneously used on a plane to irradiate the material.

[0003] However, due to differences in hardware, materials, or angles when UV lamps are installed, existing ultraviolet light sources can easily cause multiple light sources to have the same power, but different light energies at various test points on a plane. Therefore, operators need to adjust the power of all light sources individually to make the light energy at each test point consistent.

[0004] The existing process of adjusting the light source is very cumbersome, requiring manual recording of the energy level of each test point and adjustment of the corresponding light source power. After repeated tests, the energy levels of all test points are finally within a certain error range, which is time-consuming and laborious, and therefore needs to be improved. Summary of the invention

[0005] The main purpose of the present invention is to provide an irradiation intensity multi-point automatic leveling system and a leveling method, aiming to provide a leveling system and a leveling method that are convenient for power adjustment of multiple ultraviolet light sources.

[0006] To achieve the above-mentioned purpose, the present invention proposes a radiation intensity multi-point automatic leveling system, comprising a planar ultraviolet energy test panel, a multi-channel ultraviolet energy tester, an automatic leveling device, and a multi-channel ultraviolet curing controller. The planar ultraviolet energy test panel is used to receive energy from an external ultraviolet curing light source. The planar ultraviolet energy test panel is connected to the automatic leveling device through the multi-channel ultraviolet energy tester. The external ultraviolet curing light source is connected to the automatic leveling device through the multi-channel ultraviolet curing controller. The automatic leveling device is used for data comparison and ultraviolet energy adjustment according to the comparison results.

[0007] Specifically, a detection surface is provided on the planar ultraviolet energy test panel, and a plurality of mutually non-overlapping light source test points are distributed on the detection surface.

[0008] To achieve the above object, the present invention also proposes a leveling method for a multi-point automatic leveling system for adjusting irradiation intensity, comprising: S1. Adjust the target energy value T and the allowable error energy γ of up and down floating that the user needs to adjust through the automatic leveling device; S2. Import the weight distribution configuration table of the light source into the automatic leveling device; S3. Control the power of all light sources (S1, S2... Sn) to continuously increase in the minimum adjustment unit L; S4. During the process of increasing the light source, judge whether the average energy value μ of all test points (X1, X2... Xn) is in the interval of T < μ < T + γ. If it is not in the interval, increase or decrease the power of all light sources; S5. Find the point with the highest energy among all test points and mark it as Xmax; S6. Judge whether Xmax is less than T + γ; if the judgment result is: "Yes", jump to S9; if the judgment result is: "No", jump to S7; S7. Find and compare all the light source weights corresponding to the highest point Xmax in the light source weight distribution table; S8. Reduce the power of the light sources S(x - 1), S(x), S(x + 1) near the highest point Xmax (the light sources with non-zero weight values), reduce the power: L * a(x - 1), L * a(x), L * a(x + 1), and after completing the relevant operations, jump to S5 again; S9. Find the point with the lowest energy among all test points and mark it as Xmin; S10. Judge whether Xmin is greater than T - γ. If the judgment result is: "Yes", jump to S11; if the judgment result is: "No", jump to S13; S11. Prompt that the adjustment is successful, and record the power sizes of (S1, S2... Sn) and the energy values of the test points (X1, X2... Xn); S12. Complete the adjustment and end the process.

[0009] S13. Judge whether the lowest energy point and the highest energy point are adjacent; if the judgment result is: "No", jump to S14; if the judgment result is: "Yes", jump to S16 S14. Find all the light source weights corresponding to the lowest point Xmin in the light source weight distribution table; S15. Increase the power of the light sources S(x - 1), S(x), S(x + 1) near the lowest point Xmin (the light sources with non-zero weight values), increase the power: L * a(x - 1), L * a(x), L * a(x + 1); and after completing the relevant operations, jump to S9 again; S16. Find the light source weights of the two test points of the highest point Xmax and the lowest point Xmin in the light source weight distribution table; S17, the weight values ​​of the light sources S(x2), S(x3), and S(x4) that will affect both Xmin and Xmax are set to 0, and only the power L*a(x1) is increased; S18, searching again for the point Xmax with the highest energy among all the test points; S19, judging whether Xmax is less than T+γ, if the judgment result is: "yes", jump to S9, if the judgment result is: "no", jump to S20; S20, prompting that the adjustment failed, displaying Xmax, Xmin and their corresponding positions, and jumping to S12 to end the process.

[0010] The technical solution of the present invention forms an automatic leveling system by adopting a flat ultraviolet energy test panel, a multi-channel ultraviolet energy tester, an automatic leveling device, and a multi-channel ultraviolet curing controller. The automatic leveling system can automatically adjust the energy output by the light-emitting points of multiple ultraviolet light sources at the same time in conjunction with the leveling method carried in the automatic leveling system. The entire leveling process does not require human operation or intervention, which greatly improves the adjustment efficiency of the ultraviolet light source. BRIEF DESCRIPTION OF THE DRAWINGS
