Description
Technical field
The present invention relates to paint-color matching field, particularly relate to a kind of automotive paints automatic color-matching system.
Background technology
World car paint color has several ten thousand kinds, and same kind coating, and different batches exists aberration, and tenure of use is different, also can produce aberration with former paint.Therefore, as a rule, the toning reference formulation that import is put forward is comprised, can not be very accurate, must finely tune for actual conditions, even there is no reference formulation, need paint person to study model color, determine paint scheme.
The more than two kinds of tones blend of colors of different tone, capital produces a new tone, such as yellow adds blueness and obtains green, redness adds yellow and obtains orange, and blueness adds redness and obtains purple, and the toning of coating is equivalent to the subtractive process of color, take one piece of Standard colour board for preparation, first it is main for will distinguishing which kind of look mother, and which is parachrome, to judge between them relation how.
In 2K colour paint, add different white paint, just can obtain saturation degree different color, namely the depth is different, as added silver powder during 1K paints, after generalized case mass-tone is determined, and the first paint depth, rear toning phase.
In colour paint, add the pitch-dark of different amount, just can obtain the different color of lightness, if the added together or use multiple color tones different colours color matching by parachrome, also can reduce the chroma of color, color becomes dark and gloomy, and lightness reduces.
Present paint color mixing relies on manually substantially, need human eye to confirm the color that recalls whether consistent with automotive paints, and people and people feel it is different, it is inconsistent that the color that this people possible allots and that people allot the color come, car owner also not necessarily admits to rely on and feels to allot the color come, and this makes color matching extremely bother.
Patent " a kind of novel device for blending lacquer " (application number: 201220648406.7 applyings date: 2012-11-30) discloses a kind of novel device for blending lacquer, comprise casing, in casing, be provided with several primary colors paint cans, several weight testers, allotment bucket and electric-control system; Primary colors paint can is connected by the masstone paint import of pipeline with allotment bucket, and the pipeline be connected with primary colors paint can is provided with electrically operated valve; Allotment barrel cavity is provided with stirring apparatus; Weight tester, electrically operated valve, stirring apparatus are by electric control system controls, and electric-control system forms primarily of unit of account, control module and setting unit.When using this utility model, the weight that each primary colors paint can goes out paint is calculated by computing unit and setting unit, control by control module the weight that each primary colors paint can goes out paint, drastically increase the work efficiency of allotment color of paint, ensure that the repeatability of repeatedly allocating color simultaneously.
It is simple that this mode has structure, arrange rationally, the advantages such as cost of manufacture is low, but its guarantee is the repeatability of repeatedly allocating color, can not calculate the paint formulation of its correspondence according to existing model.
Patent " timber floor chromatic measuring system " (application number: 201120554052.5 applyings date: 2011-12-27) discloses a kind of timber floor chromatic measuring system, this utility model comprises single-chip microcomputer, photoelectric detector and high-definition camera instrument, photoelectric detector is for gathering monochromatic paint look and base paint look, high-definition camera instrument is for gathering timber floor background color and target paint look, photoelectric detector is connected with single-chip microcomputer through data line with the signal output part of high-definition camera instrument, and single-chip microcomputer is connected with color matching matching computer through data line.This utility model structure is simple, function is complete, with low cost, and this utility model accurately can detect required paint look and convert to normal data input color matching matching computer in, there is ideal result of use.
This mode is taken base plate color of paint, is then directly translated into paint colors information input color matching calculation machine, and then in this paint colors information, calculates formula by computing machine.Due in kind and inherently there is error between taking pictures, the conversion precision of this mode is not high enough.
