Technical Field

[0001] This utility model relates to the field of spraying robot technology, and in particular to an automatic spraying robot based on vision positioning. Background Technology

[0002] In modern industrial manufacturing systems, surface coating technology, as a core post-processing step, directly determines many key performance indicators of the final product. From a functional perspective, a high-quality surface coating can significantly improve a product's corrosion resistance, aging resistance, and mechanical strength, effectively extending its service life under harsh conditions. In terms of aesthetics, a uniform and smooth coating not only fulfills the product's design intent but also enhances brand image and market recognition. However, existing automated coating robots still suffer from the problems of requiring significant human intervention, inability to accurately locate the coating position, and inability to coat the equipment from all angles.

[0003] Therefore, it is essential to invent an automated painting robot based on vision positioning. Utility Model Content

[0010] 1. The spraying unit of this utility model is fixed to the end of the support arm by a base plate and mounted on a rotatable placement plate to fix the workpiece. Driven by a rotary motor, it achieves 60° indexing rotation. Simultaneously, a drive push rod pushes the meshing slider to move along the slide rail, driving the meshing gear and rotating shaft to control the workpiece's rotation via the connecting shaft. Combined with positioning data from a vision inspection device and the paint nozzles of the spraying structure, it achieves precise multi-angle spraying, and possesses both modular expansion and efficient collaborative operation capabilities.

[0011] 2. The spraying structure of this utility model uses a vision inspection device to locate the workpiece position in real time, and the positioning push rod precisely adjusts the spatial coordinates of the paint nozzle. Combined with the stable support of the extension frame and support frame, it enables flexible spraying at multiple angles.
