Title: APPLICATION SYSTEM FOR COATING COMPONENTS AND COATING DEVICE
Abstract:
The invention relates to a coating device for coating components with a coating agent, comprising an application system comprising the following: an application device which applies the coating agent, wherein the application device is a printhead (1, 3) which discharges the coating agent out of multiple coating agent nozzles (2, 4, 19), wherein a nozzle valve (5, 20) is attached to each individual coating agent nozzle (2), which opens for a valve opening time when a drop of coating agent is to pass out of the respective nozzle (4); a coating agent supply line (6, 22), with which the coating agent nozzles (4) of the printhead (3) are connected to one another; and a valve controller (25) for controlling the valve opening times and valve closing times of each individual valve (20), wherein the coating device comprises a robot on which at least one application device is accommodated, characterised in that the application system also comprises a pump (21), by means of which the coating agent to be applied is supplied to the coating agent nozzles (19) via the coating agent supply line (22), and in that the application system is configured such that the pump (21) operates at a constant flow rate of the coating agent during coating, and that the pressure at each nozzle (19) when opening the valve (20) is the same as when previously opening this valve (20).
