The present invention relates to an oil supply nozzle device and an oil supply device using the same. More specifically, the present invention provides a fluid supply which can provide a fluid divided in two states and a gap liner between the nozzles so as to uniformly and uniformly provide a fluid in a sol state. It is for providing a nozzle apparatus and an emulsion supply apparatus using the same.

Recently, the use of plasma display panels (PDPs) or liquid crystal displays (LCDs) is rapidly increasing in the field of computer monitors or TVs. In order to manufacture such a PDP or LCD, the front pattern electrode terminal part and the rear pattern electrode terminal part which form the electrode (address electrode and power electrode) pattern on the front glass and the rear lower glass substrate are controlled, respectively, and these front and rear pattern electrode terminal parts are respectively controlled. Tape Carrier Package (TCP) Integrated Circuit (IC) Terminal, Flexible Printed Circuit (FPC), or Flexible On-Chip (COF) IC To bond a terminal or a chip on glass (COG) IC terminal (hereinafter referred to as an 'external power connection IC terminal') such as an IC dry chip, a pattern electrode terminal portion on a glass substrate and / or an external power supply connection Adhesive must be supplied on the IC terminals.

In order to supply the adhesive mentioned above, the syringe type adhesive supply apparatus is conventionally used. More specifically, FIG. 1 shows a schematic perspective view of a syringe type emulsion feeder and adhesive supplied in the prior art.

Referring to Figure 1, the prior art adhesive supply apparatus 10 is a syringe (syringe) type, the inlet portion 12 is supplied with the adhesive from the outside; Body portion 12 for storing the adhesive supplied through the inlet portion 12; And the discharge portion 16 for discharging the adhesive from the lower body portion. Discharge part 16 has a reverse cone shape at the end, and discharges the adhesive through a fine hole (not shown) of the end.

In addition, in the adhesive supply apparatus 10 of the prior art shown in FIG. 1, adhesive discharge is performed in a mechanical manner.
