Painting Robots in Automotive Industry
Automotive Industry is well known for using painting robots for their floor plant operations due to the top-quality results. Industrial robots are very accurate and precise when applying paint or coating to a surface, do not worry about overspray.
Automotive Industry follows high standard procedures. This demanding sector is already benefiting from manufacturing robots, and also small and mid-size companies are starting in automation.
Robots are versatile and easy to install on the floor, on the rail, or on the wall according to the space of the factory plant. Besides, paint robots are very flexible, help workers from hazardous work and protect them from chemicals. Robotic painting can handle the risk of this work environment.
Painting Operations Process
For painting operations, there are two types of robot. In the case of an application in a zone that has an Atex rating, means activities that produce, explosive or potentially explosive atmospheres. Then, the robot must have a rating for this environment. Subsequently, the robot will have specific systems and protection to prevent the creation of a source of ignition.
An example of that type of robot is the Fanuc P range. For example, the P-250iB/15 is a standard robot found in car plants around the world spraying car bodies prior to assembly. Invariably, a robot of this type will have all the tubing and cabling within the robot eliminating the risk of the cable snagging and also from contamination by stray paint debris.
If the zone does not have an Atex rating, then you can use a standard robot, usually a six-axis robot to allow for high freedom of movement of the applicator. In both cases, the robot needs some form of spraying equipment—for example, the type of a bell applicator or pistol applicator.
Painting Robot by bell or pistol applicators
The bell applicator supports applications where high paint volumes are necessary with low air consumption. The bell applicator features a spinning bell cup that through centrifugal force generates small droplets of material that are then shaped into a painted cloud by a shaping airflow.
In the case of an application by pistol, the material goes directly by the airflow produced from a compressed air source. Hence, the coverage is not as great as with the bell applicator for the same airflow.
Often it will be necessary to select between various colours or materials for the application. In this case, the robot will often feature a colour changer mounted in the robot arm. Usually, a dedicated distribution system supply the material stored in tanks. Subsequently, the robot will spray the colours that receive from the system.
Manufacturing chemicals in Painting facilities
According to the article, The Impact of Health said: The main environmental impacts associated with paint come from the manufacturer of the components, rather than the manufacturing of the product itself. Following are some reason why chemicals are dangerous for human beings:
- Paint industry universally includes titanium dioxide or TiO2 for painting
- Manufacture of TiO2 is by far the greatest environmental impact
- Emissions during production including (depending on the process) CO2, N2O, SO2, NOx CH4, and VOCs
- A number of waste streams, including spent acid and metal sulfates, emanate from the manufacturing process
Choose a Robot Integrator
Some robot manufacture adds more features than others, but a good robot integrator can integrate any second-hand robots or new industrial robots from any robot manufacturer such as FANUC Robot, KUKA Robot, ABB Robot, Motoman and other. We are integrating new or used painting robots as well as complete robot systems worldwide.
