Abstract:
A control system for a paste application apparatus comprising:a setting device for setting a velocity difference between a movement velocity of a target for coating and a movement velocity of a paste layer, in order to evenly apply a paste to a front portion and a rear portion of the target for coating during application of the paste to the target for coating, wherein the paste layer is formed with a constant layer thickness on a substrate surface, the paste layer moves along a pat which is an arc-shaped path when viewed from the side together with the substrate, and the target for coating moves along the tangential direction of the arc-shaped path, along which the paste layer moves, while the target for coating is immersed to a predetermined depth relative to the paste layer, and thereby the paste is applied to the target for coating; further comprising a device for applying a paste to the target for coating via a roller, the device being provided with the roller to be supplied with a paste on the perimeter surface and a transport mechanism which transports the target for coating to the required position above the roller, wherein a paste holding portion, in which at least a part of the target for coating can enter and which can hold the paste, is arranged on the perimeter surface of the roller.
