Abstract
The utility model discloses a crest welder's water -spraying system includes the nozzle at least, the nozzle include nozzle body, the nozzle core body, spraying flow control valve and backplate, the nozzle core body install in nozzle body's centre bore, nozzle body's afterbody install spraying flow control valve, nozzle body's head install the backplate, nozzle body anterior open there is nozzle compressed air passageway, open at the middle part has the scaling powder access road, open at the rear portion has needle valve cylinder compressed air passageway, the outer bore D1 of nozzle be 1.00 1.10mm interior bore D2 is 0.95 1.05mm. The utility model discloses a less nozzle of bore, it is extravagant few to spout the long -pending little scaling powder of fogging surface. Welding machine equipment is remained the scaling powder and is obviously reduced, and the scaling powder reduction is volatilized and is remained stable, and practices thrift the scaling powder consumption, during operation scaling powder volume is few, does not influence the product surface cleanliness factor that wave -soldering welding base plate was produced.
Description
Technical field
This utility model relates to the Wave soldering of a kind of printed circuit board, a kind of crest welder
Spraying system.
Background technology
When producing Omron switch substrate, the electric elements to inserting are needed to carry out wave soldering.Wave-soldering
The operation principle of machine is by the solder of fusing--terne metal becomes design to want through electrodynamic pump or electromagnetic pump jet flow
The solder wave asked, also can by formed to solder pot nitrogen injection make to be pre-loaded with components and parts printing electricity
Road plate is realized the room machine of components and parts welding end or pin and printed circuit board pad by solder wave and is electrically connected
The solder connect.After printed circuit board enters crest welder by conveyer belt, can helping through certain form
Flux coating device scaling powder here utilizes crest, foam or the method sprayed is coated on printed circuit board.
Chinese patent CN201520092388.2 discloses the scaling powder atomizing system of a kind of crest welder, including
Nozzle, support, upper spray tank, lower spray tank, described lower spray tank is arranged on above support, described nozzle
Being positioned at support central interior on the upper side, described upper spray tank is buckled on lower spray tank, it is characterised in that: described machine
Seat side is provided with fixed mount, and described fixed mount is fixed with motor, connects and have synchronization wheel below described motor,
Connecting below described nozzle has nozzle holder, described nozzle holder to be provided above rail plate, described synchronization
Wheel is connected with rail plate by Timing Belt.This spraying system does not disclose concrete structure and the size of nozzle,
And the nozzle diameter of the spraying system that the strength that applicant uses opens up CJMS-450 crest welder is 1.3mm, nozzle
The spray angle produced is 40 °, and consequent problem is:
1, the waste scaling powder when producing.Inside equipment, welding assisted agent residuals is more.
2, nozzle spray area is relatively big, and on substrate, welding assisted agent residuals is more, personnel take substrate time have glove to refer to
Print.
3, the too much substrate surface of scaling powder is the cleanest.
Utility model content
For solving the problems referred to above that prior art exists, this utility model one to be designed can save scaling powder
The spraying system of the crest welder of substrate surface cleanliness factor can be improved again.
To achieve these goals, the technical solution of the utility model is as follows: the spraying system of a kind of crest welder
System, at least include nozzle, described nozzle include nozzle body, nozzle core body, spray flow adjustable valve and
Backplate, described nozzle core body is arranged in the centre bore of nozzle body, the afterbody peace of described nozzle body
Equipped with spray flow adjustable valve, the head of described nozzle body is provided with backplate；Before described nozzle body
Portion has nozzle compressed air channel, middle part has scaling powder access road, rear portion has needle-valve cylinder compression
Air duct；The outer bore D1 of described nozzle is 1.00-1.10mm, and interior bore D2 is 0.95-1.05mm.
Preferably, the interior bore D2 of described nozzle is 1.00mm.
Further, the outer bore D1 of described nozzle is equal with interior bore D2.
Compared with prior art, this utility model has the advantages that
1, using, due to this utility model, the nozzle that bore is less, the waste of spray area little scaling powder is few.Welding machine
Equipment residual flux significantly reduces, and scaling powder reduces volatilization and keeps stable, and saves scaling powder consumption.
2, using, due to this utility model, the nozzle that bore is less, during work, soldering flux quantity is few, does not affect crest
The product surface cleanliness factor that weldering welding substrate is produced.
3, use this utility model to be verified by the production of one month, produce the product of equal number, the most often
Needing in week to consume 3 barrels of scaling powders, now become to 2 barrels of scaling powders per week, cost reduces about more than 30%,
Reduce production cost, improve production efficiency.
