Description
Technical Field
The invention belongs to the field of automatic blending of automobile refinishing paints, and particularly relates to a volume color matching method of an automobile refinishing paint and a fixed-volume injection device of the automobile refinishing paint.
Background
When matching colors before spraying the repair paint, one of the common methods is to compare the color card with the color of the automobile, find the color card with the same color, find the color master proportion and the weight formula of each color master of the color card number from the color matching software database in the computer according to the color card number, and manually weigh the required types of color masters, mix and stir to prepare the repair paint (hereinafter, may be referred to as the automobile paint) with the same color as the color card. The automobile repair paint which is prepared according to the color card has low manual efficiency, sometimes has certain deviation with the color of the automobile, needs manual further adjustment, is labor-consuming and has higher technical requirements for a color adjuster, and can prepare the automobile paint with consistent color by an experienced color adjuster.
In the prior art, a method for finding a paint spraying formula before leaving a factory according to the model number or paint code of an automobile or measuring the surface paint of the automobile by using an optical instrument such as a spectrophotometer to obtain a paint preparation formula is also provided, so that the method for obtaining the formula can be suitable for analyzing most of the surface paint of the automobile, is relatively accurate, and reduces the error between the color of the automobile paint prepared according to the formula obtained according to the model number or the paint code and the color of the actual automobile paint. However, even then, the previously counted data indicate that there is a significant proportion of the paint on the surface of the automobile that has been color-shifted after a color match, and further manual color-matching correction is required. Therefore, the color matching of the current automobile refinishing paint has high requirement on manpower and large dependence, the manual color matching efficiency is low, especially, the color matching amount of some paint mixing shops in one day is very large and can reach dozens or hundreds of colors, one color matching worker can not finish the color matching, and some shops even need two or four color matching workers. Even so, because of the labor intensity, poor environment (color sticking everywhere, even on the body), and the long-time accumulation of technological improvement, people are still reluctant to dry the color matching worker. On the other hand, it is very difficult to recruit a good color matching worker, and the wage is low and the person is not dry. The current color matching technicians are necessary, and the paint matching profit of a paint matching shop with little color matching amount or an auxiliary business (such as an existing 4S shop) cannot be covered by the salary of a paint matching worker. Therefore, the equipment for automatically and accurately blending the color matching color master batches in the market can achieve the aims of improving the efficiency, reducing the blending technical requirements and reducing the labor cost.
In fact, in recent years, enterprises have developed automatic car refinish paint tinting machines. But does not form a stable product for market.
It is known that the existing mature and universal automobile paint color mixing method in the world adopts a weight ratio mode, and color master batches are manually poured out from a paint bucket to be weighed, matched and mixed. According to the weight requirement of the required color matching color master, the color master is manually poured out from a color master barrel with a pulp cover on the upper part through a pulp outlet on the pulp cover. Weighing the required color matching color master batch on an electronic scale. The color matching color master in each formula is poured out from the color master barrel and weighed to reach the required weight. Stirring, mixing and color matching color master batch to finish color matching of the paint with the required color. The slurry cover has the functions of stirring and manually controlling the pouring of color master batches. At present, the color matching formula of manufacturers (such as new-in, DuPont, PPG and Basff) for manufacturing the color matching color master batch of the automobile refinishing paint in the world is designed according to the weight ratio.
The advantages of manual paint pouring and color mixing in weight ratio are two:
1 pour out the look female convenience of required volume from look female bucket, it is also convenient to control the volume of pouring out: and manually controlling to gradually slow down the pouring speed of the color master when the required weight on the weighing scale is observed to be fast, so that the color master slowly approaches the required pouring weight, and stopping pouring the color master until the required color master weight is finally reached. Pouring out and weighing the required weight of other color matching color masterbatches according to the same method;
2, several color concentrates needing color matching can be poured into a container to be directly stirred uniformly: for example, if three color concentrates are required for one color, the weight of each color concentrate is 1.1 g for color A, 2.2 g for color B and 3.3 g for color C, an empty barrel can be placed on an electronic scale, and the weights are reset. The color master A was poured into the empty barrel until the weight of the scale indicated 1.1 g. Resetting the electronic scale, and pouring color master B until the weight displayed by the electronic scale is 2.2 g; and then, resetting the electronic scale, and pouring the C color paste until the electronic scale displays 3.3 g. And finally, uniformly stirring the three color masterbatches by using a stirring ruler to finish color matching and color mixing.
The use of weight toning is the first natural choice for the toning history. In order to avoid that the proportion of color master is not accurately known and the required amount of the color master cannot be accurately controlled by empirical color matching, the most conveniently realized weight proportion method accurate color matching is generated on the basis of the empirical color matching.
It is also true theoretically that volume-scale matching is used. However, theoretically established volume ratio color schemes are difficult to achieve in practice. The idea of obtaining color matching color master batch with required volume by a volume ratio color matching method comprises the following steps: consider 1: the color master is manually poured into the measuring cup, and the poured color master is observed and controlled by human eyes according to the volume scale measuring mark position of the measuring cup. However, this has a problem that, due to the characteristics of the colored paint, the accuracy of the volume amount of the color master when the position of the graduated measuring scale of the measuring cup is observed by human eyes to determine the volume amount of the color master does not reach the accuracy of 0.1 gram weight, particularly, the volume of the measuring cup is large when a large amount of colored paint is mixed, the sectional area of the measuring cup is larger, and the error of the human eyes to determine whether the color master reaches the specified position of the measuring scale is larger, and the color mixing accuracy requirement of 0.1 gram cannot be met at all. In addition, the inaccurate manual volume color matching method is much more difficult and fussy in actual operation than the weight ratio color matching method, so that effective color matching cannot be realized; consider 2: using a gravity cup method: because of the wall-hanging residue of the color master and the discontinuity of volume metering, the required volume is difficult to realize in practical application; consider 3: manual syringe volumetric metering method: because the color master batch at the position of the injection tube head for extracting the color master batch is hung and taken, precision errors can be caused, the removal of the hung color master batch is not only troublesome but also not environment-friendly, and if the color master batch is not cleaned, the color master batch can flow to the position of the outlet of the needle tube head to influence the error guarantee below 0.1 g. Similarly, the viscous color masterbatch is manually injected, even a person with small strength pushes the viscous color masterbatch, the diameter of the injection tube is reduced, the injection force can be reduced, the single pushing precision is improved, the large-amount color masterbatch is accurately injected and needs to be pumped into a color masterbatch container for color masterbatch extraction for many times, the hung color masterbatch at the opening of the injection tube needs to be removed in each extraction, the accumulated error is increased due to the increase of the times, the 0.1 g error is more difficult to control at the moment, the color matching is more complicated and more frequent than the currently used weight ratio method, the color matching industry can certainly select a simple and easy-to-realize weight ratio method for color matching, and the color matching can not select the volume ratio method which is troublesome and difficult to ensure the precision.
The person skilled in the art does not consider the use of volume ratios to achieve color matching after the advent of weight ratio color matching methods. Since from the past to the present, the industry has been judged not to replace the color mixing and matching by weight ratio after analyzing the above-mentioned influence factors, which is a technical prejudice to the profession in the mind of the industry.
Disclosure of Invention

Mainly because volume measurement is inaccurate, the equipment after being pushed out can not meet the requirement, foreign first-class manufacturers try to solve the problem for a long time, and people generally think that the automobile paint can only be measured by weight ratio.
