This practical model relates to the field of robotic painting, specifically robotic painting methods and systems with three-day vision guidance. Currently, spraying in my country's processing industry mainly relies on traditional manual methods. Additional polishing and spraying are often required to meet user requirements for film thickness and appearance quality. Therefore, manual spraying is labor-intensive, inefficient, and long-term exposure to paint and solvents is harmful to workers' health. Currently, recruitment issues, rising wages, and other factors are beginning to impact various industries. Furthermore, industrial equipment in the processing industry generally has complex structures and high product quality requirements. To address these issues, machine replacement plans should be considered to improve production efficiency, enhance quality, and reduce operating costs. Therefore, the demand for intelligent spraying robots is more urgent in general industrial production. What are the programming-free spraying methods, systems, and processes using 3D vision-guided robots?
With the rapid development of intelligent manufacturing and the widespread adoption of industrial robots, painting robots, with their high painting quality, high automatic painting efficiency and high return on investment, are accelerating the transformation of traditional painting processes.
A painting robot, also known as a spraying robot, is an industrial robot capable of automatically spraying or applying other coatings. A painting robot mainly consists of a robot body, a computer, and a corresponding control system. Hydraulically controlled painting robots also include a hydraulic power source, such as an oil pump, oil tank, and engine. Typically, they employ a joint structure with 5 or 6 degrees of freedom, allowing for a large range of motion and complex movement trajectories. Its wrist usually has 2-3 degrees of freedom, enabling flexible movement. More advanced color painting robots utilize flexible wrists that can bend and rotate in any direction. Its movements are similar to a human wrist, penetrating easily processed parts through a small orifice and spraying their inner surfaces. Robot spraying can be controlled via manual commands or point-to-point programming. Painting robots are widely used in industries such as furniture, ceramics, sanitary ware, automotive parts, and metals.
Current painting techniques require manually designing the painting trajectory based on the object's shape and then writing the trajectory code so that the painting robot can execute the code. Furthermore, products of different shapes and sizes require individual programming, which increases labor costs and is inefficient. Even after introducing intelligent robotic painting, painting programming still requires manual operation. This is time-consuming and labor-intensive for different product needs, thus urgently requiring an intelligent, non-programming method.
