[0030] The working principle of the utility model is as follows: the circuit board processing glue dispensing machine is additionally provided with a dustproof mechanism 5 and a temperature regulating mechanism 6. Before using the circuit board processing glue dispensing machine, it is necessary to pre-connect the glue dispensing machine body 2, the conveyor belt 3, the air pump body 503, the heating wire 604 and the cooling fan 607 to electricity and connect to the control terminal. When using the circuit board processing glue dispensing machine, first start the conveyor belt 3 to convey the circuit board body 4 from left to right. The dustproof mechanism 5 adopts a wrapping structure to wrap the glue dispensing machine body 2 and the circuit board body 4 on the inside.
