Abstract: A coating device has a coating head that dispenses coating material toward a vehicle body. The coating device also includes a supply device that has a circulation path for circulating the coating material between a reservoir storing the coating material and the coating head, and is capable of controlling the pressure of the coating material flowing through the circulation path. The coating device includes an arm having the coating head and the supply device, wherein the coating robot performs coating of the vehicle body while moving the coating head wherein the coating head moves at a first speed toward a coating start position to start coating the vehicle and moves at a second speed different from the first speed when it reaches a specific position in a movement path to the coating start position.

Abstract: The present disclosure provides a painting robot and a painting method using the painting robot. The painting robot includes: an arm control unit which controls operation of the robot arm; a head control unit which controls driving of nozzles of the nozzle head; a distance measuring device which measures the distance between the painting portions and the nozzle discharging surface; and an image processing portion which forms a three-dimensional model for painting, which is a three-dimensional model, based on the painting coverage of the vehicle expected to be painted. The head control unit, based on the distances measured between the painting portions in the three-dimensional model for painting and an imaginary nozzle head or the distances measured by distance measuring device, controls to discharge paint from nozzles with distances within the prescribed range, and to not discharge paint from nozzles outside the prescribed range.
