The embodiment of the invention provides a glue dispensing device and relates to the field of liquid crystal display panel production. According to the glue dispensing device, the position, corresponding to a seal agent, of a liquid crystal display panel on an object stage, is heated by a heater, so that water vapor accumulating on the inner periphery of an exhaust hole is removed; then, photosensitive glue is dispensed by a coating pressure head at the involution interface of the seal agent, and the temperature of the involution interface of the seal agent becomes relatively high due to waste heat generated after the liquid crystal display panel is heated by the heater, so that the coating pressure head is coated with the photosensitive glue, and the infiltration capacity of the infiltration capacity at relatively high temperature is improved; a transmission mechanism is arranged on the object stage or a glue dispensing assembly, and the object stage or the glue dispensing assembly moves in the transmission direction under the action of the transmission mechanism, so that after one position is heated by the heater, the coating pressure head moves to the position for glue dispensing and the heater moves to the next position for heating; and accordingly, through such continuous operation, the working efficiency of the glue dispensing device can be improved when the glue dispensing effect is guaranteed.
