Mobile robot automatic spraying device and mobile robot automatic spraying control system and method

Abstract

The invention discloses a mobile robot automatic spraying device and a mobile robot automatic spraying control system and method. The mobile robot automatic spraying control system comprises a visualrecognition unit, a main control unit, a graphic reconstruction unit, a trajectory programming unit, a spraying unit and a robot control unit, wherein the visual recognition unit performs processing on collected image information of a workpiece to obtain geometric information; the graphic reconstruction unit performs optimization processing on the geometric information of the workpiece to obtain agridding three-dimensional model of the workpiece; the trajectory programming unit automatically recognizes a spraying area and calculates a spraying trajectory strategy to obtain a spraying trajectory file; the spraying unit plans a spraying path according to a positional relation between the workpiece of a robot and the spraying trajectory file, and generates codes capable of being executed bythe robot; and the robot control unit controls the industrial robot to execute a spraying action according to the code file. According to the invention, a visual recognition based trajectory planningmethod is adopted, the spraying trajectory is automatically planned in allusion to a workpiece to be sprayed, the robot automatically completes the paint spraying work, the work flexibility is increased, and the programming workload is reduced.

Description

technical field [0001] The invention belongs to the technical field of robot automatic spraying application, and more specifically relates to a visual recognition-based movable robot automatic spraying device, control system and method. Background technique [0002] Surface spraying is a crucial link in the product processing chain, and manual spraying has certain defects: First, the quality of manual spraying is unstable, and many factors such as spray gun settings and process parameters are determined by manual experience, resulting in the failure of the entire product. The quality is uneven; second, in order to ensure that the spraying thickness is uniform and there are no dead ends, the operator will apply glaze repeatedly, resulting in a large waste of glaze and low production efficiency; third, the spraying operation environment is harsh, and long-term work is harmful to the health of workers. Serious harm. [0003] In recent years, with the popularization of robot ap...

Serious harm

However, offline programming is highly dependent on accurate part models and the technical experience of programmers. When there are many types of parts, the programming workload is heavy. If there is no part model, it is necessary to remodel the part.

In addition, the application scenarios of the current robot spraying system are fixed and cannot meet the needs of changing application scenarios

[0005] In short, the existing programming mode of fixed robots has many limitations in the application of surface spraying, such as high site requirements, poor work flexibility, and heavy programming workload.
