Description

Technical Field

[0001] The invention relates to the technical field of paint touch-up equipment, and in particular to a paint touch-up robot. Background Art

[0002] Spray painting is a method of using a spray gun to disperse paint into uniform and fine droplets with the help of air pressure and apply it to the surface of the object to be painted. It can be divided into air spray painting, airless spray painting and electrostatic spray painting. During the spray painting process, special attention should be paid to safety to avoid inhalation and skin contact.

[0003] Touch-up painting: The first type of touch-up painting work is the process of repainting some parts that have not been painted well on the parts to be painted. The second type of touch-up painting work is the process of repainting the parts to be painted after the paint has been worn or damaged after a period of use.

[0004] For the first type of touch-up work mentioned above, the existing touch-up robots still have the following disadvantages:

[0005] (1) For some areas of the parts to be painted that have not been sprayed well, the position of the spray head needs to be re-determined when spraying again, which is not convenient for touch-up painting;

[0006] (2) After the clamping unit clamps the workpiece to be painted, it is inconvenient to adjust the spatial position of the workpiece to be painted, which makes it inconvenient to perform touch-up work.

[0007] Based on the above situation, a paint touch-up robot is urgently needed to solve the above problems. Summary of the invention
