PAINTING ROBOT

Provided is an inkjet-type vehicle painting machine capable of keeping temperature elevation of a nozzle head to a certain temperature or less. The painting robot 10 comprises a power supply means 120 for supplying power to drive a piezoelectric substrate 62 of a nozzle head 53, and a robot arm R1 for moving the nozzle head 53. The nozzle head 53 is provided in an explosion-proof housing 70 equipped with an explosion-proof construction. A heat dissipation means 90 that dissipates heat generated from the nozzle head 53 within the explosion-proof housing 70 is attached to the nozzle head 53. A temperature measurement means 100 for measuring the temperature of the heat dissipation means 90 is attached to the heat dissipation means 90. Also, there is provided a power cutoff means 110 for cutting off the supply of power from the power supply means 120 to the piezoelectric substrate 62 on the basis of a detection signal from the temperature measurement means 100 when the temperature measurement means 100 measures that a stipulated temperature has been reached.
