A Spraying Robot Based on Visual Recognition and Positioning

Abstract

The invention discloses a spraying robot based on visual recognition and positioning, which comprises a main section mechanical arm, a second section mechanical arm movably connected to the top of the main section mechanical arm, a rotating arm rotatably connected to the front end of the second section mechanical arm, and a rotating arm movably connected to the rotating arm. The three-section mechanical arm at the front end of the arm, the top of the three-section mechanical arm is provided with a monitoring probe, the monitoring probe is movably connected with the three-section mechanical arm through the probe support frame, and the front end of the monitoring probe is interspersed with a camera lens, so The front end of the camera lens is provided with a lens cleaning structure, and the inside of the three-section mechanical arm is provided with an adjustable nozzle structure, and the adjustable nozzle structure includes an electric telescopic rod fixedly connected to the inside of the three-section mechanical arm. The invention can control the angle adjustment of the thinner spray head through the three-segment mechanical arm, and the spray head is easier to move in the small hole, which solves the problem that the rotation of the robot wrist cannot spray the inside of the small hole workpiece well.

Description

technical field [0001] The invention relates to spraying equipment, in particular to a spraying robot based on visual identification and positioning. Background technique [0002] Spraying robot, also known as painting robot, is an industrial robot that can automatically spray paint or spray other coatings. The painting robot is mainly composed of a robot body, a computer and a corresponding control system. The hydraulically driven painting robot also includes hydraulic oil sources, such as oil pumps and oil tanks. And motors, etc., mostly adopt 5 or 6 degrees of freedom joint structure, the arm has a large movement space, and can do complex trajectory movement, and its wrist generally has 2 to 3 degrees of freedom, which can move flexibly. More advanced The wrist of the painting robot adopts a flexible wrist, which can be bent in all directions and rotated. Its action is similar to that of a human wrist. It can easily penetrate into the workpiece through a small hole and sp...

Problems solved by technology

[0003] However, in actual implementation, the wrist of the robot is relatively thick, and the inside of the workpiece with small holes cannot be sprayed well only by the rotation of the robot wrist.
