Claim 0:
1. A glue dispensing device, comprising:
a base comprising a pressure control chamber and a glue tube body, wherein the pressure control chamber is located inside the base, the glue tube body extends from one end of the base to another end, and the glue tube body penetrates the pressure control chamber;
a pressure control unit being coupled to the pressure control chamber;
a quantitative glue supply unit being disposed at the one end of the base and coupled to the glue tube body; and
a glue dispensing needle being disposed at the another end of the base and coupled to the glue tube body,
wherein the pressure control unit provides a pressurized air to the pressure control chamber to increase a pressure inside the pressure control chamber, the increased pressure inside the pressure control chamber compressing the glue tube body causing a glue inside the glue tube body to be squeezed to the glue dispensing needle, thereby allowing the glue to overcome a surface tension to be stably output.
