Title:
WEIGHT-VOLUME MIXED COLOR MATCHING METHOD FOR VEHICLE REFINISHING PAINT, MATERIAL TAKING MECHANISM, AND AUTOMATIC COLOR MIXER
Document Type and Number:
WIPO Patent Application WO/2020/057464
Kind Code:
A1
Abstract:
A weight-volume mixed color matching method for a vehicle refinishing paint, a material taking mechanism of a color mixer, and the automatic color mixer. The method comprises the following steps: (1) finding out a vehicle data identification card on which a color number is printed from a vehicle body to be refinished, finding out a color code of the vehicle, or finding out the closest color card code by comparison; finding out a weight formula of the used refinishing paint by using a reader or a computer color matching system; or, using a spectrophotometer to detect the surface of a complete coating of the vehicle body to be refinished, and outputting the weight formula of the refinishing paint by means of calculation; (2) obtaining a volume formula of the corresponding refinishing paint by conversion according to the weight formula of the refinishing paint and the measured specific gravity of color master batches; (3) calculating the types of the required color master batches and the volume required for each color master batch according to the volume formula of the refinishing paint and the area to be refinished; (4) according to the required color master batch types and volume, obtaining the required color master batches by a color master batch out-letting mechanism and the material taking mechanism of the vehicle refinishing paint color mixer; the material taking mechanism of the color mixer comprises a lifting driving mechanism (50) provided on a color mixer body (1); the lifting driving mechanism (50) is provided with a bracket (51) capable of moving up and down and configured to place a cup supporting plate (6) and a paint mixing cup; a conveyor belt conveying mechanism is horizontally provided on the color mixer body (1); the automatic color mixer comprises the color mixer body (1) and a controller; the color master batch out-letting mechanism is provided on a color master batch turntable (4); the color master batch out-letting mechanism comprises slurry outlet openings (23) controlled by a valve; the slurry outlet openings (23) of each color master batch out-letting mechanism are arranged in a circle on the color master batch turntable (4).
