COOLING DEVICE FOR PAINTING ROBOT AND PAINTING ROBOT INCLUDING THE SAME

摘要

The present invention includes a supply part which supplies an explosion-proof gas into a painting robot to maintain a higher pressure inside the painting robot than a pressure outside, and an explosion-proof line which supplies the explosion-proof gas supplied from the supply part into the painting robot. The explosion-proof line includes an injection hole for injecting the explosion-proof gas toward the driving part in order to cool the driving part which provides a driving force for driving the painting robot. According to the present invention, the lifespan of the driving part is extended. Therefore, costs for replacement and maintenance processes can be reduced by preventing the driving part of providing a driving force for performing a painting process from being damaged or broken due to overheat.
