A spraying robot, also known as a painting robot, is an industrial robot that can actively paint or spray other coatings. The painting robot is mainly composed of the robot body, the computer and the corresponding control system. The hydraulically driven painting robot also includes a hydraulic oil source, such as an oil pump, oil tank, and motor. Most of them use 5 or 6 degrees of freedom joint structure, the arm movement space is large, can do complex orbital movements, and the wrist generally has 2-3 degrees of freedom, and the movement is sensitive. The more advanced painting robot wrist uses a flexible wrist that can be twisted and rotated in all directions, and its action is similar to that of a human wrist, and it is easy to reach the inside of the workpiece through a smaller hole and spray its inner and outer surface. Painting robots are generally driven by hydraulic pressure, which has the characteristics of fast action speed and good explosion-proof performance, and can be educated through hand instructions or point instructions Painting robots are widely used in automobiles, instruments, electrical appliances, enamel and other industries.
The main advantages of spraying robots:
(1) Large flexibility and large range of operating capacity.
The scope of work is large, and the audit possibilities are large
The spray can be done both inside and outside the exterior.
It can complete the mixed production of a variety of different models, such as cars, station wagons, pickup trucks and other body mixed line production.
(2) Improve the quality of spraying and the amount of materials used.
Spray profiling *** track to improve the appearance of the quality uniformity of the coated coating film.
Reduce the amount of overspraying and cleaning organic solvents, and improve the utilization rate of learning materials.
(3) Convenient operation and protection, offline programming, greatly shortening the on-site debugging time.
Offline programming, greatly shorten the commissioning time.
The plug-in structure and modular education planning can complete the rapid development of the economy and replace the components, greatly shortening the maintenance operation time.
Everything is accessible and easy to protect.
(4) High utilization rate of equipment, spraying robot utilization rate as high as 90%-95%.
2. Different characteristics of spraying industrial robots:
(1) Air spraying robot
Air spraying robot, also known as low-pressure air spraying, spraying machine relies on low-pressure air to make the sprayed paint form an atomized air flow on the surface of the object (wall or wood surface), compared to the hand brush there is no air spraying brush marks, and the plane is relatively uniform, the unit operation time is short, can effectively shorten the construction period However, there is a gas jet splash phenomenon, there is a paint waste phenomenon, a close view, you can see very fine particles There is a general air spraying selection of general air compressors in the decoration industry, relatively speaking, a machine is multi-purpose, the cost of investment is low, and there are also air extraction air sprayers, Self-falling air sprayers and other special machinery.
(2) Airless spraying robot
Airless spraying robots can be used in the construction of high-viscosity coatings and sharp edges, even for some spray project gaps. Depending on which can be divided into multiple mechanical types of pneumatic airless spraying, airless sprayer electric, internal combustion airless sprayer, active sprayer. It should also be noted that if the surface of the metal spraying process is preferred, metal coatings (enamel) are preferred.
