Problems solved by technology

[0006] However, in this method, due to the difference in the injection speed and injection angle of each head, in the case of actual coating, there is a gap between the heads. Poor coating state, possibility of streaks on the film
In addition, it is necessary to prepare the substrate for the experiment, and it is also necessary to discharge it for the experiment, and waste of the coating liquid is generated.

Embodiment Construction

[0023] Embodiments of the present invention will be described by taking an inkjet coating device as an example.

[0024] exist Figure 1~2 , is a schematic diagram showing six inkjet heads mounted as an inkjet coating device.

[0025] In this inkjet apparatus, there is provided a substrate stage 20 on which a substrate 21 as an object to be coated is placed and fixed on the stage by a suction suction mechanism not shown. A moving frame 2 configured to straddle the substrate stage 20 and move in the front-rear direction is provided. On the movable frame 2, three inkjet heads 1 (hereinafter simply referred to as heads) are provided so as to be movable in the longitudinal direction of the frame (left-right direction) on the front side, and three heads 1 are similarly provided on the rear side. Both legs of the moving frame 2 are provided with a moving table 17 provided with a linear motor, and by driving the linear motor, it can move in the front-rear direction on a linear rail...

Abstract

The technical problem the invention object to resolve is to measure the bias starting from the target location from the initial installation, and to manufacture product substrates with high yield after effective and high precision correction, in an apparatus of using an ink jet head with a plurality of nozzles to coat the material on the substrate. In the invention, a nozzle camera is used to process position correction to all the heads beforehand by taking the central head as a benchmark in the a plurality of ink jet heads provided on the apparatus and measuring the position of the two terminal nozzles (a space d) of the head 1. Furthermore, the material pattern is coated on a substrate for modulation, the bias (a space D) from the target location is measured by observing the position ofthe coating points, and then XYtheta direction position correction of the nozzle between heads is performed by calculating the moving quantity from the bias.

Description

technical field [0001] The present invention relates to a liquid drop discharge device for discharging liquid droplets, and more specifically, to a multi-head inkjet liquid droplet application device of a head moving frame moving type. Background technique [0002] An inkjet head is a device that uses air bubbles or piezoelectric elements to discharge a small amount of liquid droplets with high precision. An inkjet coating device is a device that uses it to achieve high-precision and high-secret droplet coating. , attracting attention in recent years, and is expected to be applied in various fields. [0003] As described in Patent Document 1, along with the increase in the size of the substrate to be coated, the number of inkjet heads actually mounted on the device also increases, and when applying high-precision coating to the substrate, variations in the mounting of these inkjet heads occur. The inconsistency of the nozzle position will have a great influence on the coat...
