The regulating drive member drives the piston rod to periodically flow the glue in the liquid outlet passage out of the dispensing needle. The dispensing drive drives the cartridge assembly to dispense the workpiece.

The above automatic dispensing device precisely adjusts the amount of dispensing by providing a piston rod inside the dispensing head assembly. In addition, the third driving member periodically drives the piston rod to hydraulically discharge the glue in the liquid outlet channel and drop into the rubberizing tray to prevent the glue located at the outlet of the dispensing needle from solidifying and blocking the dispensing needle, thereby realizing the automatic point. The glue device has the technical effect of precisely controlling the amount of dispensing and preventing the dispensing needle from being clogged.
