Embodiment 1

[0029] according to the above figure 2 and image 3 As shown, an automatic pigment blending device was prepared, in which the standard light source is four bright white LEDs, and the color sensor adopts the existing TCS230 chip. The single-chip microcomputer adopts the STC89C52 single-chip microcomputer, and the single-chip microcomputer 3 is powered by a unified 5V DC power supply. The power amplifier circuit adopts triode amplification and intermediate relay output. The model of the selected solenoid valve is 2W-08. mm and valve body material is brass, powered by 12V DC power supply, the pressure sensor is a resistance sensor, the container is airtight and does not react with the pigment, the operation control program of the single-chip microcomputer is: start → white balance, extract correction factor → detect sample color , get the RGB value → data processing, convert RGB to CMY, get three critical control points → control the opening of the first solenoid valve → detect...

Abstract

The invention provides an automatic mixing device for pigment and relates to a device which is used for color combination. The automatic mixing device for the pigment comprises a color recognition portion and a color mixing portion, wherein the color recognition portion mainly comprises a standard light source, a color sensor, a single chip microcomputer and an operation control procedure. The single chip microcomputer is synchronously connected with the standard light source and the color sensor through lines, and the standard light source and the color sensor are arranged in a light shielding cover. The color mixing portion mainly comprises a single chip microcomputer, a power amplifying circuit, an electromagnet, a pressure sensor and a container. The single chip microcomputer is connected with the electromagnet through a power amplifying circuit, one end of the electromagnet is installed at the bottom of the container, and the other end of the electromagnet is provided with a pipeline which is guided out of the other end of the electromagnet. The pressure sensor is connected with the single chip microcomputer through lines, a round bucket which is used for containing mixed pigment is arranged on the pressure sensor, and the round bucket is arranged below the pipeline which is guided out of the other port of the electromagnet. The automatic mixing device for pigment overcomes the shortcomings that automatic recognition can not be achieved in the prior art in the color recognition process and precise color mixing rate in a color mixing link can hardly be achieved.

Description

technical field [0001] The technical solution of the present invention relates to a device for color synthesis, specifically an automatic pigment blending device. Background technique [0002] Most of the surfaces of furniture, walls and some equipment are painted with paint and other coatings, one is for aesthetics, and the other is to prolong the service time, but after a long period of use, some parts will be damaged, which not only affects the appearance, but also affects its use performance and longevity. In order to solve such problems, it is necessary to match the corresponding color to be repaired. At present, most of the popular paint matching devices on the market use database-based color matching, which rely on a large number of experiments to obtain a huge database, obtain quantified color cards, and then manually complete the matching between the required color and the color card to output the color. This method has poor color matching accuracy and low efficie...
