First, the background and principle of the present invention will be described before explaining the measurement and reproducing method of the plating solution and the surface oxidation solution using the RGB color sensor according to the present invention.

The present invention includes copper plating, strike copper plating, nickel plating, chromium plating, zinc plating, cadmium plating, tin plating, gold and gold alloy plating, silver plating, and other precious metals including rhodium, ruthenium, platinum, including electroplating and electroless plating. , Palladium) Oxidation chemicals for maximum surface bonding through plating and surface treatment, more specifically black or brown oxide chemicals, including all metals and chemicals It has its own color.

In other words, nickel sulfate (NiSO ₄ · 7H ₂ O) is blue, chromium (Cr) is red, copper (Cu) is blue, and nickel (Ni) is green.

In addition, like the other plating solutions, the plating solution may be added an acidic or alkaline liquid, a brightening agent, a humectant, or the like to the base chemical.

These additives are slightly different for each company according to each plating or surface reducing agent, and the plating solution varies in color depending on the content of copper depending on the use, or in the case of metals for various plating or surface oxides. Various impurity contamination during plating, that is, impurity content such as iron (Fe), silver (Ag), lead (Pb), etc. can be increased, which must be managed as impurities affecting the plating quality. Concentration management was performed through equipment or wet analysis, which required a lot of time and manpower.

Therefore, in the case of plating or reduction reaction, as all metals and chemicals meet, consumption and aging of chemicals due to chemical reaction proceeds, and as the metal component of the solution changes, the color of the initial solution begins to change. Together, the initial objective function is reduced.

The copper plating solution may be slightly different in concentration, but has a dark blue color, and gradually starts to be red when working with iron, and is green when it is contaminated with lead.

In the present invention, a spherical vector analysis is introduced and analyzed for the first time as a method of detecting a unique color.

To date, the chromaticity analysis table is a method of the second surface chromaticity table xyZ used in the CIE, whereas the spherical expression method cannot be displayed by overlapping white and black portions.

FIG. 2 shows a reference diagram for explaining the color space of the CIE, and this CIE shows a basic color distribution, as shown in FIG. 2, wherein the color of one point is located at any point on the spherical surface. The size of the sphere is determined by the relationship between lightness and saturation.

3 is a reference diagram for explaining a color matching function of RGB, and FIG. 4 is a reference diagram showing a correlation between height vector values of RGB.

As shown in FIG. 3, the color of RGB is obtained by r + b + g = δA, rb = δX, rg = δY, and bg = δZ with reference to values of representative wavelengths of CIE. Find the vector of his sum. This value is the vector value of * L represented in the CIE.

After converting the CIE basic drawing to the vector variation, the state is indicated as shown in FIG. 4. Here, the reason for the vector analysis is a groundbreaking method in which the spherical representation is mathematically processed instead of the xyZ method shown in the existing CIE, and the color space of the CIE has a spherical shape as shown in FIG. Although it is expressed, the black and white portions overlap each other and have a limitation that they can be displayed on two dimensions.

FIG. 5 is a reference diagram for explaining a process of obtaining a composite point of a vector component of a three-dimensional analysis of a sphere, and the three-dimensional analysis of such spherical body is a composite of a vector component,

F (x, y, z) = 0

r (u, v) = x (u, v) i + y (u, v) j + z (u, v) k

ru * rv ≠ 0, r (u, v) = acosvcosui + acosvsinuj + asinvk

FIG. 6 is a reference diagram of a diagram showing the relationship between the X-Y vectors, and FIG. 7 is a reference diagram of the diagram showing the relationship between the xy-Z vectors.

Through this process of principle, the positioning of white and black automatically becomes very easy.
