Glue dispensing apparatus with heating unit and glue dispensing method

A glue dispensing apparatus comprising:

• a container configured for receiving glue, and comprising an end, the end defining a receiving hole extending through the end;
• a glue dispensing head connected to the end of the container and configured for dispensing the glue, the glue dispensing head comprising a plug partially received in the receiving hole, and the plug defines through holes communicated with the receiving hole;
• and
• a heating unit mounted on the container, the heating unit comprising:
• a temperature sensor configured for detecting a temperature of the glue;
• a heating component;
• and
• a controller electrically connected to the temperature sensor and the heating component, wherein the controller compares the temperature of the glue with a predetermined temperature range, controls the heating component to heat the glue when the temperature of the glue is equal to or less than a lower limit of the predetermined temperature range, and controls the heating component to stop heating the glue when the temperature of the glue is equal to or greater than an upper limit of the predetermined temperature range.
