AI Technical Summary

Technical Problem

The prior art is difficult to accurately control the coating width and position of the coating liquid, especially when the coating width and position change, it is difficult to accurately apply the coating liquid to a predetermined position.

Method used

A width adjustment device and a cross-moving device are introduced into the coating equipment, and the width and coating position of the coating liquid are adjusted in real time through a computer control system to ensure that the coating liquid is accurately applied to the predetermined position.

Benefits of technology

It is realized that when the coating width and position change, the coating liquid can be applied accurately to the predetermined position to ensure the accuracy and consistency of the coating effect.

Abstract

In the present invention, when a coating liquid (p) is discharged from a slit-like discharge port (33) of a coating nozzle (30) to an object (W) to be coated, and the coating nozzle and the object to be coated are relatively moved in a coating direction (Y) to apply the coating liquid to the surface of the object to be coated, a width adjusting means (50) or the like for adjusting the width of the coating liquid discharged from the slit-like discharge port is provided, a width difference or the like between the width of the coating liquid discharged from the slit-like discharge port and the width of the coating liquid actually applied to the object being coated is calculated by using a calculating means (62) on the basis of a storage means (60) having stored therein arithmetic expressions in various kinds of coating condition data, and the width adjusting means or the like is controlled by a control device (63) on the basis of the calculated width difference or the like.
