When spraying, whether it is powder spraying or spray painting, atomization is necessary to ensure uniformity. The components of the paint are all chemical substances, and the paint mist and other volatile gases are flammable. The spraying operation site is like a gasoline station, which is flammable and explosive. The robot is electrically controlled, and if improperly protected, it can cause a fire and explosion.
Therefore, in painting projects, international standards require the use of explosion-proof robots, and the common scene of explosion-proof robots is also in painting projects. Therefore, it is often referred to as explosion-proof robots or explosion-proof robots as painting robots.
From a security perspective:
No one wants to have a production accident, so everyone agrees that explosion-proof equipment must be used for spraying. Because once a safety accident occurs, the impact on equipment, employees, factories, and society is enormous. Therefore, the spraying site must be explosion-proof.
Starting from technical means:
Can't an explosion-proof robot be sprayed? From a purely technical perspective, not only explosion-proof robots can meet the requirements of the spraying process, but other explosion-proof means, such as adding protective covers, protective clothing, and protective layers, can also achieve the purpose of blocking combustible gases and dust, and can also achieve the purpose of explosion-proof. However, explosion-proof is not only necessary to prevent flammable paint mist, but also requires heat dissipation and ventilation for the equipment itself. In addition, it is also necessary to meet the requirements that do not affect the normal operation of the equipment, work paths, maintenance, and other daily operations. External protection is not an easy task.
Starting from national standards:
Currently, there are increasingly high environmental requirements for factories. Using robots to spray can increase adhesion, reduce resource use and pollution, and more conducive to meeting environmental requirements.
On the other hand, new spraying projects have strict requirements for equipment and environmental impact assessment at the time of approval, and even factories that fail to meet the requirements cannot be built. In response to the fact that the price of explosion-proof machines is much higher than that of ordinary industrial robots, local industrial enterprises have applied for financial subsidies for spray painting workshops, which, on the one hand, promotes enterprise innovation and moves towards environmentally friendly production methods, on the other hand, reduces enterprise pressure and promotes automation and intelligent processes.
What are the advantages of the protective function of the spraying robot?
Painting robots not only have protective functions but also have protective measures. The IP protection level reaches IP55, and explosion-proof measures include:
1) The electric wires and motors of the automatic spraying robot are placed inside the housing and are not exposed,
2) The robot is equipped with a combustible gas detector inside.
3) The sealing ring prevents external air from entering the robot housing. Sparks can explode when mixed with combustible gas. Due to the combustible gas detector installed inside the automation robot, once the detector detects combustible gas, it will alarm and shut down.
