Compressed air is fed into the glue bottle (syringe) and the glue is pressed into the feed tube connected to the piston chamber where it is heated and the temperature is controlled to obtain a good and stable viscosity. The dispensing needle (valve) of the automatic dispensing machine in lieu of the dispensing process uses a ball-seat construction where the glue fills the void left by the ball as it retracts from the seat. When the ball returns, the force generated by the acceleration interrupts the flow of glue, causing the glue to eject from the needle and drip onto the board to form a glue spot. Automatic dispensing machine for dispensing generation process, eliminating the traditional methods produced by the phenomenon of glue pulling tail when the generation of dispensing processing, there will not be dispensing needle wear or interference with other parts of the problem. As a result, there is no nozzle (needle) damage to the automatic dispenser, and no scrap due to substrate bending and damage by the needle nozzle.
