Problems solved by technology

[0006] However, the conventional coating apparatus has a problem in that the shape of the paint discharged through the discharge port of the nozzle varies according to the shape of the tip of the nozzle so as not to be constant, so that the cross-sectional shape of the paint applied to the substrate is not constant.

Embodiment Construction

[0024] Preferred embodiments of the nozzle according to the present invention will be described below with reference to the accompanying drawings.

[0025] First, if figure 1 As shown, the coating device having the nozzle according to the first embodiment of the present invention includes a pallet 10 on which a substrate S is installed, a coating head unit support frame 20 arranged above the pallet 10, and a coating head unit supporting frame 20 arranged on the coating surface in a movably manner. The head unit supports the coating head unit 30 on the frame 20 and has the nozzle 70, and a control unit (not shown) that controls the operation of applying paint.

[0026] The pallet moving unit 40 is provided under the pallet 10 to move the pallet 10 in a direction (Y-axis direction) perpendicular to a direction (X-axis direction) in which the coating head unit support frame 20 extends. The coating head unit moving unit 50 is provided on the coating head unit support frame 20 to ...

Abstract

The invention discloses a nozzle which is optimized in shape, thereby enabling the upper surface of paint coated on a substrate to be shaped into a plane parallel to the upper surface of the substrate.

Description

technical field [0001] The invention relates to a nozzle for use in a coating device for coating paint mixed with frit. Background technique [0002] In the process of manufacturing a flat panel display such as an OLED (Organic Light Emitting Diode) display, an LCD (Liquid Crystal Display), a plasma display, or a field emission display, in order to keep the internal space between a pair of substrates hermetically sealed, A predetermined interval between a pair of substrates, a paint mixed with glass frit is applied to either one of the pair of substrates, and then the substrates are bonded to each other. [0003] This coating is in the form of a sealant in which frit in powder phase is mixed with an organic solvent. Apply it to the upper surface edge of the substrate. Subsequently, when the coated substrate is subjected to a drying and heating process, the organic solvent in the coating volatilizes, with the result that the glass frit remains on the substrate. An adhesive...
