Automatic color mixing and painting device and method

Method for automatic painting using RGB color detection and CMY color mixing spray

This technology is an automatic color mixing and painting mechanism that uses an enclosure and a specific color temperature light source to precisely detect the color of a painting target, eliminating the influence of external lighting. A control unit compares the detected color with a reference color to adjust the CMY paint mixing ratio and air spray volume in real time.

In industrial painting, relying on the human eye for color matching leads to low precision in touch-up work, and workers face environmental hazards such as working while suspended by ropes or in confined spaces.

This technology integrates a color sensor, enclosure, light source, compressor, and air flow regulator onto a mobile robot. It automatically diagnoses the color of a specific area, determines the CMY paint mixing ratio based on the comparison results, sprays the paint, and establishes a feedback control system that re-inspects the color after painting to correct any errors.

Key Features:

• Detecting the RGB color of a pre-determined reference area that serves as the standard for painting
• Sequentially moving across the target painting area using location-based services to detect the RGB color of each section
• Determining whether the RGB color information of the reference area matches the RGB color information of the target area
• If the colors differ, determining the CMY mixing ratio, adjusting the air volume and discharge rate for spraying, and performing post-painting calibration through re-detection
