Technical field
The present invention relates to a kind of hand-held spray guns, are applied particularly to carry out scaling powder spraying to pcb board before pcb board welding.
Background technology
Wave-soldering is always that printed circuit board component welds indispensable technique.Wherein the spraying of scaling powder has one
Fixed technical requirements, such as require the coat uniformity obtained, and the thickness of coating is suitable etc..Current scaling powder atomizing device
Using compressed air as caused by spraying shower nozzle negative pressure, scaling powder is suctioned out simultaneously, together sprayed by shower nozzle.But such a side
The scaling powder particle that formula sprays is big, and spraying is uneven, and not only coating quality is low but also causes the waste of scaling powder.
At the same time, ultrasonic tr-ansducer can convert electrical energy into mechanical oscillation, can be by ultrasonic vibration piece by liquid
Atomization, and particle is very small.
The content of the invention
The technical problems to be solved by the invention be to provide it is a kind of scaling powder can be atomized completely after the spray gun that sprays.
The technical solution adopted for the present invention to solve the technical problems is：A kind of ultrasonic atomizatio spray gun, including spray gun spray nozzle
Device, the chassis interior of spray gun are provided with a fog water content, cell body bottom installation ultrasonic vibration piece, and air outlet is installed at the edge of cell body,
Air outlet grate, ultrasonic vibration piece bottom installation ultrasonic tr-ansducer are opened up on air outlet；
Spray gun fluid reservoir is installed on base top, and the fluid reservoir bottom opens up liquid outlet, spray gun fluid reservoir inner hollow, top installation
The top cover that can be turned on, spray gun fluid reservoir are sunken in the place that the position that it is installed coincides with air outlet.
The outward flange suit spray gun external cavity of base, the inner surface of external cavity form annular with the outer surface of spray gun fluid reservoir
Cavity, there is opening on above-mentioned spray gun external cavity top cover, spray gun spray nozzle device is installed in the opening.
Spray gun spray nozzle device as described above includes shower nozzle fog inlet and shower nozzle air inlet；Shower nozzle fog inlet is used for ultrasonic mist
Scaling powder suction after change, shower nozzle air inlet are used to produce negative pressure at spray nozzle.
Moreover：Above-mentioned cell body bottom is also equipped with one and goes out liquid switch bottom and liquid level sensor, described
The liquid outlet of spray gun fluid reservoir installs out liquid switch top.How much liquid level sensor is controlled whether by scaling powder in cell body
Think to continue to install scaling powder additional in cell body.
Moreover：Above-mentioned air outlet bottom installation aerophor, the aerophor are used for helping after atomization
Solder flux is blown in toroidal cavity.
The beneficial effects of the invention are as follows：
Ultrasonic atomizatio spray gun of the present invention, is sprayed after by using ultrasonic tr-ansducer, scaling powder is atomized completely by spray tip, can be made
There is the particle of very little when obtaining scaling powder spraying, it is easier to realize even application, coating quality is better than traditional approach, improves PCB
Quality during plate weld.

Embodiment
Below in conjunction with the accompanying drawings and embodiment describes the specific embodiment of the invention：
Fig. 1,2,3 show the structure of one embodiment of the invention, as illustrated, in the present embodiment, are provided with inside the base 6 of spray gun
One fog water content, ultrasonic atomization process are completed in groove, and cell body bottom installation ultrasonic vibration piece 9, an air-out is installed at the edge of cell body
Mouthfuls 5, air outlet grate is opened up on air outlet 5, and an aerophor is preferably installed in the bottom of air outlet 5 again, and the aerophor is one small-sized
Blower fan, for fog to be blown out by air outlet 5, the bottom of ultrasonic vibration piece 9 installation ultrasonic tr-ansducer.The installation spray of the top of base 6
Opening, i.e. liquid outlet are arranged at rifle fluid reservoir 4, the bottom of fluid reservoir 4, and the top cover of spray gun fluid reservoir 4 can be turned on, for adding liquid
Body.Spray gun fluid reservoir 4 is not a regular geometry cavity, and its installation site place corresponding with the air outlet 5 that base 6 is installed is recessed
It is trapped into.
The outward flange suit spray gun external cavity 3 of base 6, the external cavity 3 and spray gun fluid reservoir 4 as described above are all installed
Afterwards, the outer surface of the inner surface of external cavity 3 and spray gun fluid reservoir 4 forms cavity, and air outlet 5 as described above is by the liquid after atomization
Body is delivered to this cavity area.There is opening on the described top cover of spray gun external cavity 3, traditional spray gun spray nozzle is installed in the opening
Device, including, shower nozzle fog inlet 11 and shower nozzle air inlet 2.When compressed air is entered by shower nozzle air inlet 2 and is sprayed by shower nozzle
When, the liquid that can be sucked simultaneously by shower nozzle fog inlet 11 after atomization, the liquid for eventually passing through ultrasonic atomizatio sprays by spray gun spray nozzle
Go out.
Above-mentioned cell body bottom is also equipped with one and goes out liquid switch bottom 10 and liquid level sensor 8, above-mentioned spray gun fluid reservoir 4
The also corresponding installation one of liquid outlet go out liquid switch top 7.Described going out liquid switch top 7 and go out liquid switch lower part 10 forms out
Liquid switching device, the device when described liquid level sensor 9 monitor tank liquid less than when, then the switch open, spray gun
Liquid in fluid reservoir 4 is flowed into inside cell body, when liquid level sensor 9 monitors that liquid completely, has then gone out liquid switching device closure, no
Carry out injecting liquid operation.Described liquid level sensor 9 is when monitoring not having in cell body the i.e. spray gun fluid reservoir no liquid of liquid
Then whole device is stopped.
As shown in Fig. 2 after liquid atomization in spray gun, by the effect of air outlet along outside liquid storage outdoor face and spray gun
The annular space that cavity inner surface is formed rises, and after external compression air is entered by the air inlet of spray gun, is sprayed at spray nozzle
Go out, negative pressure caused by shower nozzle sucks the liquid after atomization along shower nozzle fog inlet, is finally also sprayed by spray nozzle.
