[0039] During use, the power is turned on, the glue storage cylinder 14 is placed into the heat preservation sleeve 402, the upper cover 401 is covered, and then the heat preservation cylinder 4 is threadedly connected to the installation groove 301. The dispensing head 15 passes through the through hole in the center of the installation groove 301 and passes through the center of the straightening ring 20. Then, the feeding end of the glue storage cylinder 14 is connected to the discharging end of the material barrel through a hose. When dispensing, the X-axis driving rail 8 and the Z-axis driving rail 5 work, enabling the dispensing head 15 to move up, down, left, and right, while the Y-axis driving rail 2 works to drive the dispensing table 26 to move back and forth, facilitating the dispensing head 15 to perform dispensing processing on various positions of the workpiece to be dispensed. During processing, the straightening ring 20 can move up and down under the action of the hydraulic telescopic rod 18. When moving, it can not only straighten the dispensing head 15 to prevent it from bending but also heat various positions of the dispensing head 15. The stirring motor 10 works to drive the stirring frame 12 to rotate, which can not only stir the glue material to make the glue material heat more evenly but also clean the inner wall of the glue storage cylinder 14.
