Brief introduction: spraying robot, also known as spray painting robot (spray robot), is an industrial robot that can automatically spray paint or other coatings. in 1969, it was founded by Norwegian Trallfa company (
Spraying robot, also known as spray painting robot, is an industrial robot that can automatically spray paint or spray other coatings. It was invented by Norwegian Trallfa Company (later incorporated into ABB Group) in 1969. The painting robot is mainly composed of the robot body, the computer and the corresponding control system. The hydraulic paint robot also includes the hydraulic oil source, such as the oil pump, the oil tank and the motor. Multi-use 5 or 6 degrees of freedom joint structure, the arm has a larger movement space, and can do complex trajectory movement, the wrist generally has 2 to 3 degrees of freedom, can be flexible movement. The more advanced painting robot wrist adopts a flexible wrist, which can be bent in all directions and can be rotated. Its action is similar to that of a human wrist, which can easily extend into the workpiece through a small hole and spray its inner surface. The painting robot is generally driven by hydraulic pressure, which has the characteristics of fast action speed and good explosion-proof performance. It can be taught by hand or point and position. Painting robots are widely used in automobiles, meters, electrical appliances, enamel and other industries.
One: the main advantages of spraying robot:
(1) Large flexibility and large working range.
A: The scope of work is large and the audit possibility is large.
B: The inner surface and the outer surface can be sprayed.
C: It can realize the mixed production of various models, such as car, station wagon, pickup truck and other body mixed production.
(2) improve the quality of spraying and material utilization.
A: profiling spray track accurate, improve the uniformity of the coating film and other appearance spray quality.
B: Reduce the amount of overspray and the amount of cleaning solvent, and improve the material utilization rate.
(3) easy to operate and maintain, can be off-line programming, greatly shorten the field debugging time.
A: can be off-line programming, greatly shorten the field debugging time.
B: plug-in structure and modular design, can achieve rapid installation and replacement of components, greatly shorten the maintenance time.
C: all parts of the maintenance of good accessibility, easy maintenance.
(4) The utilization rate of the equipment is high, and the utilization rate of the spraying robot can reach 90% 95%.
Two: the type of spraying robot features:
(1) Gas spraying robot
Air spraying robot is also called low-pressure air spraying. The spraying machine relies on low-pressure air to form atomized air flow after the paint is sprayed out of the muzzle to act on the surface of the object (wall surface or wood surface). Compared with hand brush, air spraying has no marks, and the plane is relatively uniform, the unit working time is short, which can effectively shorten the construction period. However, there is a splash phenomenon in gas spraying, and there is a waste of paint. When viewed at close range, extremely fine particles can be seen. Generally, air spraying adopts the air compressor commonly used in the decoration industry. Relatively speaking, one machine has multiple functions and low investment cost. There are also special machines on the market such as air-pumping spraying machines and self-falling air-pumping spraying machines.
(2) airless spraying robot
The airless spraying robot can be used for the construction of high viscosity paint, and the edge is clear, and it can even be used for some spraying projects with boundary requirements. Depending on the type of machinery, it can be divided into pneumatic airless spraying machine, electric airless spraying machine, internal combustion airless spraying machine, automatic spraying machine and so on. In addition, it should be noted that if the metal surface is sprayed, it is best to use metallic paint (enamel)
