[0022] Specifically, the precision dispensing head 203 moves to the top of the through hole 107, extends through the through hole 107 to the inside of the water collecting tank 106, and heats the water inside the water storage chamber 101 through the heating rod 103. The water is sucked into the water pipe 104 through the micro water suction pump 102 and then sprayed out through the output port of the precision dispensing head 203, so that the hot water cleans the glue inside the precision dispensing head 203, avoiding the situation where the glue solidifies at the nozzle of the precision dispensing head 203 due to the low temperature and is inconvenient to clean, thereby solving the problem of residual glue solidifying inside the precision dispensing head 203 when not in use, causing dispensing blockage.

[0028] Specifically, by placing the parts to be glued on the top of the glue dispensing table 301, turning on the device through the switch 108, and driving the threaded ring 305 to move longitudinally through the rotation of the servo motor 303, the slide plate 302 moves on the inner side of the carrier 3, so that the glue dispensing table 301 drives the parts to be glued to move longitudinally, which facilitates the precision glue dispensing head 203 to perform precision glue dispensing operations at different positions;

[0029] Furthermore, a glue box 4 is fixedly installed on one side of the support frame 2, a pressure gauge 401 is fixedly installed on the front end of the glue box 4, a knob 402 is rotatably connected to the front end of the glue box 4, and a connecting pipe 403 is fixedly connected between the precision dispensing head 203 and the glue box 4;

[0030] Specifically, glue is input into the precision dispensing head 203 through the connecting tube 403 for dispensing, and the pressure inside the glue box 4 is detected by the pressure gauge 401 to avoid uneven glue spraying by the precision dispensing head 203 due to excessive pressure.
