Biliquid refrigeration pressure control dispenser
Technical field
The utility model is related to the technical fields of point glue equipment, and in particular to a kind of biliquid refrigeration pressure control dispenser.
Background technology
It needs to bond between each parts in electronic product, needs to carry out Accurate Points glue, root on product in advance
According to the characteristic for bonding product, usually use two-component glue, two-component glue that can be generated heat, when mixing if temperature is not
It reduces, mixed glue will soon be killed, and glue is killed in order to prevent, and glue is held when the product that do not put
Continuous dumping, can cause the waste of glue.
Furthermore in two-fluid glue dispenser, two-component glue is pressurizeed and is pressed into mixing tube, by being pointed out by syringe needle, glue is let out
Pressure, in the state of stablizing plastic emitting, pressurization and the pressure release of glue form a dynamic balance state.But if syringe needle is damaged or oneself
Gel quantity reduces when dynamic drop glue interval time is long, and syringe needle gel quantity is less than the gel quantity of each component glue dispensing valve, mixing tube internal pressure
Power starts to put aside, and at the same time, gel quantity reduces, and syringe needle, the glue in mixing tube can be caused slowly to react after reduction, most
It is fully cured eventually.Screw rod constantly squeezes into glue into mixing tube when automatic glue-dropping, causes glue pressure increasing, finally from each
A junction exudation, causes quick-fried glue, causes dispenser damage, dispensing error.
