spray painting robot

brief introduction
Spray robot, also called spray painting robot, is an industrial robot that can spray or spray other coatings automatically. In 1969, it was invented by Norway Trallfa (after ABB group). The spray painting robot is mainly composed of the robot body, the computer and the corresponding control system. The hydraulic driven spray painting robot also includes the hydraulic oil source, such as oil pump, oil tank and motor. 5 or 6 degrees of freedom joint structure, the arm has a larger motion space, and can do complex trajectory motion, its wrist generally has 2~3 degrees of freedom, flexible movement. The wrist of a more advanced painting robot adopts flexible wrist, which can be flexed in all directions and can be rotated. Its action is similar to that of a man's wrist. It can easily reach the inside of the workpiece through smaller holes and spray its inner surface. The paint spraying robot is generally driven by hydraulics, which has the characteristics of fast action speed and good explosion-proof performance. It can be taught by hand holding instruction or point number display. Spray painting robots are widely used in automobile, instrument, electrical appliances, enamel and other process production departments.

The main advantages of the spraying robot (1) are flexible. The scope of work is great. (2) improve the quality of spraying and the utilization of materials. (3) easy to operate and maintain. It can be off-line programming, greatly reducing the on-site debugging time. (4) high utilization of equipment. The utilization rate of the spraying robot can reach 90%-95%.

Category characteristics
1. Gas spraying robot

Gas spraying robot is also called low pressure gas spraying, and the spray machine relies on low pressure air to form atomization air after spray out of the muzzle on the surface of the object (wall or wood surface), and the air spray is brushless than the hand brush, and the plane is relatively uniform and the unit working time is short, and the short working period can be effectively reduced. However, there is splashing phenomenon in the air spraying, and there is a waste of paint. When we look at it closely, we can see very fine graininess. Generally, gas spraying is used in the general air compressor in the decoration industry. It is relatively a multi - use machine and low investment cost. There are also special machinery, such as gas spraying machine, self falling gas spraying machine and so on.

Two. Airless spraying robot

The airless spraying robot can be used for the construction of high viscosity paints, and the edges are clear, and even can be used for spraying projects with boundary requirements. Depending on the mechanical type, it can be divided into pneumatic airless sprayer, 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 spray treated, it is best to use metallic paint (varnish).

Main advantages
One, good flexibility.

(1) the activity radius is large and flexible.

(2) the spraying of the inner surface and the outer surface can be realized.

(3) it can realize the mixed line production of various types of cars, such as cars, wagon, pickup trucks, etc.

Two. Improve the quality of spraying and the utilization of materials.

(1) the accuracy of profiling spray trajectory, improving the uniformity of coating and so on.

(2) reduce the amount of spraying and the amount of cleaning solvents, and improve the utilization rate of materials.

Three. Easy to operate and maintain.

(1) offline programming can greatly shorten the commissioning time.

(2) plug-in structure and modular design can achieve rapid installation and replacement of components, and greatly shorten the maintenance time.

(3) all components have good accessibility and easy maintenance.
