Spray painting robot called Robot (spraypaintingrobot), is available for automatic spray painting or other coating of industrial robots in 1969 (later incorporated into the abb Group) was invented by Norwegian Trallfa company. The painting robot is mainly composed of a robot body, a computer and a corresponding control system. The hydraulically driven painting robot also includes a hydraulic oil source such as an oil pump, a fuel tank and a Motor. More than 5 or 6 degrees of freedom joint structure, the arm has a large movement space, and can do complex trajectory movement, the wrist generally has 2 to 3 degrees of freedom, flexible movement. The more advanced painting robot wrist uses a flexible wrist that can be bent and rotated in all directions. Its action is similar to that of a human wrist. It can easily penetrate into the inside of the workpiece through a small hole and spray the inner surface. The painting robot is generally driven by hydraulic pressure, and has the characteristics of fast action speed and good explosion-proof performance. It can be taught by hand teaching or point display. Painting robots are widely used in the production of automotive, instrumentation, electrical appliances, enamel and other processes.
The main advantages of the painting robot (1) are flexible. The scope of work is large. (2) Improve the quality of the spray and the rate of material use. (3) Easy to operate and maintain. Can be programmed offline, greatly reducing on-site debugging time. (4) High equipment utilization. The utilization rate of the painting robot can reach 90%-95%.
Type characteristics
First, there is a gas spray robot
Air-spraying robots are also called low-pressure air-spraying machines. The spraying machine relies on low-pressure air to cause the paint to form an atomizing airflow on the surface of the object (wall or wood surface) after being sprayed out of the muzzle. The air spraying is not related to the hand brush. Brush 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 in the air spray, and there is a waste of the paint. When viewed at a close distance, extremely fine particles are visible. Generally, there are air compressors that are commonly used in the decoration industry. Relatively speaking, a multi-purpose machine has low investment costs, and there are also special machines such as air-extracting air-spraying machines and self-dropping air-spraying machines on the market.
Second, airless spraying robot
Airless spray robots can be used for the construction of high-viscosity paints with sharp edges and can even be used in some spray projects with boundary requirements. Depending on the type of machine, it can be divided into pneumatic airless spraying machine, electric airless spraying machine, internal combustion airless spraying machine, automatic spraying machine and so on. It should also be noted that if the metal surface is sprayed, it is best to use metal paint (magnetic paint).
