Description

Technical Field

[0001] The present invention belongs to but is not limited to the field of laser marking technology, and in particular relates to an integrated control system and method for a color laser marking machine. Background Art

[0002] Laser marking technology is widely used in various industrial fields for marking, engraving and pattern drawing on different materials. Traditional laser marking systems can usually only generate single-color marks, which limits their use in application scenarios that require multi-color marks and complex patterns. With the development of science and technology and the increase in market demand, color laser marking technology has gradually become an important marking technology. Color laser marking can achieve multiple-color markings on the same workpiece, improving the aesthetics of the mark and the ability to convey information. However, existing color laser marking systems have problems such as complex control, inconvenient operation, and low accuracy in marking different colors. They also face the problem of insufficient progress, the printed patterns are not clear or the position is offset, and the color management module may not be able to accurately convert colors.

[0003] Therefore, there is an urgent need for an integrated and intelligent color laser marking control system to improve the flexibility and accuracy of marking. Summary of the Invention

[0011] The user interface is connected to the control unit and provides a friendly operation interface, allowing users to input and edit marking content, select color schemes, set marking parameters, etc.; it supports real-time preview and adjustment to meet different application requirements.

[0012] Furthermore, the color management module can convert the input image data into color instructions recognizable by the laser emission module through a software algorithm.

[0013] Furthermore, the color instruction includes parameters such as wavelength, power and marking speed of the laser required for each color.

[0014] Furthermore, the image processing unit can perform image segmentation, feature extraction and color optimization to improve marking quality.

[0015] Furthermore, the laser emission module may be composed of multiple groups of laser sources, each group of laser sources emitting lasers of different colors; the control unit achieves color mixing and transition by precisely controlling the power and emission timing of each group of laser sources.

[0019] S3: The sensor (visual camera) and feedback system monitor the marking effect in real time, compare the marking effect captured by the visual camera with the color image initially input, and then adjust the laser emission parameters to ensure that the final mark meets the set requirements;

[0020] S4: The user interface provides a variety of functions, including image editing, color selection and marking preview, allowing users to operate and adjust conveniently.
