Description of the Invention: [Technical Field] The present invention generally relates to a nozzle cleaning device capable of automatically cleaning a nozzle and a glue applicator having the nozzle cleaning device. [Prior Art] In general, flat panel displays (FPDs) are image display devices that are thinner than conventional televisions or monitors that use cathode ray tubes (Braun tubes). Examples of flat panel displays that have been developed are liquid crystal displays (LCDs), plasma display panels (PDPs), field emission displays (FEDs), and organic light emitting diodes (OLEDs). The liquid crystal display in such a flat panel display is an image display device for displaying a desired image in such a manner as to supply a data signal to a liquid crystal cell arranged in a matrix according to image information, thereby controlling the transmittance of the liquid crystal cell. Since liquid crystal displays are thin and light, and have many other advantages such as low power consumption and low operating voltage, liquid crystal displays are widely used. A method of generally manufacturing a liquid crystal panel for a liquid crystal display will be described as follows: First, a color light-emitting sheet and a common electrode are formed on an upper glass panel. Thereafter, a thin film transistor (TFT) and a halogen electrode are formed on the lower glass panel corresponding to the upper glass panel. Next, the alignment film is applied to the upper glass panel and the lower glass panel, respectively. Thereafter, the alignment film is rubbed to provide a liquid crystal molecule pretilt angle and an alignment direction to be formed in the liquid crystal layer between the alignment films. Thereafter, a glue pattern is formed by applying a glue to at least one of the glass panels, 201242672 to maintain a gap between the glass panels, to prevent liquid crystal from leaking and to seal the space between the glass panels. Next, a liquid crystal layer is formed between the glass panels to complete the liquid crystal panel. In the manufacture of a liquid crystal panel, a glue applicator is used to form a glue pattern on the glass panel. The applicator includes a pallet placed on the frame for arranging the glass panel, a coating head unit equipped with a glue-containing syringe and a nozzle communicating with the syringe, and a coating head unit support frame supporting the coating head unit. The applicator forms a glue pattern on the glass panel when changing the position of the nozzle relative to the glass panel. In other words, the applicator moves the nozzle mounted on the coating head unit in a vertical (z-axis) direction to maintain a constant gap between the nozzle and the glass panel, and moves the nozzle and/or the glass panel to the horizontal (X or γ) Axis) direction. When the nozzle is moved, the glue is applied from the nozzle to the glass panel to form a glue pattern.

In the case where the glue is applied to the nozzle = 埠, the outlet 埠 of the nozzle may be blocked. Therefore, it may not be possible to discharge the glue from the nozzle 3 as well. Therefore, the procedure for forming a pattern on the glass panel is three, and there is an operation of checking whether the glue adheres to the nozzle outlet and removes the glue from the nozzle. However, in the prior art, the operator visually inspects whether there is a glue mouth. If the nozzle is contaminated with glue, the operator must manually clean the spray = shift from the mouth.
