Abstract
This coating system (2) for coating a workpiece (W1) with a liquid coating product, includes an ultrasonic spray head (14) for generating droplets of coating products, an electrode (32A) for generating an electrostatic field (E) between the electrode and the ultrasonic spray head (14) and a high-voltage generator (52) connected to the electrode for supplying the electrode with high voltage. The shape of the electrode (32A) is advantageously configurable on the basis of the geometry of the workpiece (W1).
Claims21
A coating system for coating a workpiece with a liquid coating product, the coating system including an ultrasonic spray head for generating droplets of coating product, wherein the coating system further includes:
- an electrode for generating an electrostatic field between the electrode and the ultrasonic spray head, and
- a high-voltage generator connected to the electrode for supplying the electrode with high voltage, wherein the high-voltage generator is integrated in a sub-module which also includes a discharge resistor and a connector, said sub-module defining two housings, where the high-voltage generator and the discharge resistor are respectively received, and a connection housing where the connector is received to connect the high-voltage generator and the discharge resistor,
- and wherein the electrode is shaped according to a geometry of the workpiece and supported by a base part which includes the high-voltage generator.
