Telescopic spray-coating robot for spray-coating shell plating

Abstract

The invention discloses a telescopic spray-coating robot for spray-coating a shell plating. The telescopic spraying robot comprises a rack, a moving module, an adhesion module, a telescopic mechanicalarm, a spray gun and a detection feedback module, wherein the moving module, the adsorption module, the telescopic mechanical arm, the spray gun and the detection feedback module are arranged on therack. The moving module comprises crawler belt assemblies arranged on the two sides of the rack and pneumatic motors driving the crawler belt assemblies, and the rotating direction of the robot is controlled by controlling the rotating speed difference of the pneumatic motors. The adhesion module comprises permanent magnetic adhesion units arranged on the crawler belt assemblies and a vacuum adhesion unit arranged in the middle of the rack. The spray gun is arranged on the rack through the telescopic mechanical arm and driven by a stepping motor. Firstly, the robot can be attached on the surface of a ship body in different intensity and can walk with multiple degrees of freedom; secondly, a complex-curvature portion on the surface of the ship body can be spray-coated, the spray gun is always kept perpendicular to the outer surface of the ship body, and the telescopic spray-coating robot is suitable for operation of wall faces at any angle; and thirdly, the operation condition can be tracked in real time through the detection feedback module.

Description

technical field [0001] The invention relates to the technical field of wall-climbing robots, in particular to a telescopic spraying robot used for coating ship outer plates. Background technique [0002] In the ship painting industry, the painting of ship outer plates is currently mainly done by manual spraying. The quality of spray paint depends on the proficiency of workers and the state of work, and the quality is not stable. There is a risk of falling when workers are painting on elevated vehicles for a long time, and in order to ensure a uniform operation track, once workers get on the vehicle for painting operations, they need to stay on the vehicle for a long time, causing physiological hazards such as not being able to drink water and excrete on time. At the same time, the paint mist and dust generated by the painting operation will cause huge damage to the workers' health. [0003] At present, the ship's outer plate coating robot can meet the coating operation of t...

Problems solved by technology

However, the mechanical arm of this patent cannot realize telescopic and multi-degree-of-freedom rotation, and the movement mode of the mechanical arm is single, which cannot realize the spraying operation of complex curved surfaces on the hull surface
