Abstract
A coating device for coating a cathode-ray tube with a layer has a booth for accommodating a cathode-ray tube to be coated. The booth houses a coating robot with a spray nozzle for spraying a coating solution onto the cathode-ray tube in the booth to coat a layer on the cathode-ray tube. The inner wall surfaces of the booth are lined with a water-containing member which is supplied with water from a water supply pipe connected to the booth. An air-conditioning unit is mounted on the booth for controlling the temperature and humidity in the booth. The cathode-ray tube is introduced into the booth from a conveyor through an opening defined in a wall of the booth and fitted with a selectively closable door.
