Biliquid refrigeration pressure control point glue equipment
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 point glue equipment.
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.By way of refrigeration, the time that can do glue increases, and saves glue.
Another aspect, when using two kinds of glues, the mode of tradition supply glue dispensing valve glue is to be supplied respectively to by sebific duct, this
Sample a. wastes glue;B. bubble is had in glue, causes dispensing bad.And when using two-component glue, glue bucket installation side
Just, it is easy, by glue barreled mistake, to influence dispensing effect.
Furthermore in double hydraulic control presses dispenser, two-component glue is pressurizeed and is pressed into mixing tube, by being pointed out by syringe needle, glue
Water pressure release, in the state of stablizing plastic emitting, pressurization and the pressure release of glue form a dynamic balance state.But if syringe needle is impaired
Or automatic glue-dropping interval time it is long when gel quantity reduce, syringe needle gel quantity be less than each component glue dispensing valve gel quantity, mixing tube
Interior pressure 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 occur instead after reduction
It answers, is finally fully cured.Screw rod constantly squeezes into glue into mixing tube when automatic glue-dropping, causes glue pressure increasing, most
It is oozed out eventually from each junction, causes quick-fried glue, cause dispenser damage, dispensing error.
