Description
Technical field
The utility model belongs to circuit board cleaning technique field, relates in particular to a kind of spray equipment that is used for printed circuit board cleaning machine.
Background technology
In the circuit board welding dress connection technology of electron trade, after components and parts on the circuit board are finished processing by multiple welding procedure, on the plate face because the influence of solder flux, scolder and environment, the components and parts pin is detained the residue of some down, these residues directly affect product quality, must clean could guarantee circuit board electricity function index finally with the working life of the stability, reliability and the complete machine that guarantee electronic product, so cleaning circuit plate assembly is a very important and technical stronger job.
Since ethanol is scrubbed or ultrasonic waves for cleaning exist cleaning performance bad, to shortcomings such as circuit board damage are big, at present circuit board components is cleaned and just develop towards water base cleaning direction, the water base cleaning equipment that uses on the market has separate type water washer and one body swimming cleaning machine now.No matter which kind of water base cleaning machine all will be used spray equipment and come the cleaning circuit plate in the cleaning process.Existing spray equipment is an integral structure, and its installation, dismounting, replacing assembly are difficult for all realizing that its rotation is motor drive mode or is the ball bearing passive type.Therefore, existing spray arm needs isolated system one cover rotating driving device or adds other rotating parts, has increased the manufacturing expense of spray system, has also caused the waste of the energy simultaneously.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, spray equipment that is used for printed circuit board cleaning machine of being easy to install and change assembly.
The purpose of this utility model is achieved through the following technical solutions:
The spray equipment that is used for printed circuit board cleaning machine accordingly, comprise spray arm, coupling assembling and several drive nozzles, spray arm is provided with a water inlet and several drive nozzle installing holes, coupling assembling comprises clamping ring, connector pedestal and attaching nut, coupling assembling is connected with the water inlet of spray arm by clamping ring, by the attaching nut clamping ring is linked to each other with the connector pedestal again and be fixed on the working cavity, have several through holes on the clamping ring of coupling assembling, each drive nozzle all is arranged on the drive nozzle installing hole.
By the above-mentioned technical scheme that provides as can be seen, the utility model is connected with spray arm respectively with drive nozzle by coupling assembling, has characteristics simple in structure, as to be easy to install and change assembly.

Embodiment
This embodiment provides a kind of spray equipment that is used for printed circuit board cleaning machine, as shown in Figure 5, this device comprises spray arm 1, coupling assembling 2 and several drive nozzles 3, spray arm 1 is provided with a water inlet 1-1 and several drive nozzle installing holes 1-2, coupling assembling 2 comprises clamping ring 2-1, connector pedestal 2-2 and attaching nut 2-3, coupling assembling 2 is connected with the water inlet 1-1 of spray arm 1 by clamping ring 2-1, by attaching nut 2-3 clamping ring 2-1 is linked to each other with connector pedestal 2-2 again and be fixed on the working cavity, have several through holes 2-4 on the clamping ring 2-1 of coupling assembling 2, each drive nozzle 3 all is arranged on the drive nozzle installing hole 1-2.
Concrete, spray arm 1 (as shown in Figure 1) is the main body of spray equipment, can (can be circular for the integral type tubular structure, it also can be rectangular configuration, here all with the tubular structure narration), drive nozzle installing hole 1-2 is asymmetric formula distribution and is provided with on spray arm 1 axis direction, be issued to bigger spray area coverage and realize that area coverage is even thereby be implemented in less nozzle quantity.Respectively distributing on the front and back cambered surface at spray arm 1 two ends one becomes 30 ° rotational pressure nozzle installing hole 1-3 with spray arm central horizontal face, thereby realizes spray arm rotation and can also increase the spray effect automatically.
On the clamping ring 2-1 of coupling assembling 2 (as shown in Figures 2 and 3), have several through holes 2-4, concrete quantity is generally 10～20, wherein with 14～16 the bests, and clamping ring 2-1 need be stretched in the spray arm 1, water is directly entered in the main body of spray arm 1, can't form direct pressure to spray arm 1, the frictional resistance when rotating to reduce spray arm 1; But along with increasing of current, internal pressure in the coupling assembling 2 increases gradually, thereby influence the rotation of spray arm 1, at this moment, the inner pressure that increases will discharge to the outside by several through holes 2-4 on the clamping ring 2-1, make coupling assembling 2 internal pressures be in a balance all the time, thereby can not influence the rotation of spray arm 1, make spray arm 1 rotation more brisk.And coupling assembling 2 adopts external screw thread to be connected with spray arm 1 and encapsulation process is carried out in the junction.
Drive nozzle 3 (as shown in Figure 4) can be fan-shaped drive nozzle, be connected with spray arm 1 by internal thread, and encapsulation process is carried out in the junction.Corresponding drive nozzle 3 produces high impact forces when using fan-spray and spraying are evenly distributed, and the drop size is little of medium, and the spray edge spraying overlay area that is tapered automatically when several drive nozzles 3 overlap spraying is even.
This spray equipment can divide upper, middle and lower-ranking to place when being applied in the main frame cavity of purging system of printed circuit board cleaning machine, and middle level spray equipment drive nozzle be that symmetry is placed up and down, quantity than about two-layer many.The spray equipment of said structure can solve problems such as existing cleaning machine scavenging period is long, the spray arm reparation is expensive greatly, cleaning efficiency is low, cleaning performance difference.Pressure and flow that spray system drive nozzle in the existing cleaning machine provides are little, and scavenging period is long and can't clean thoroughly, and existing spray equipment is integral structure, change accessory and can't realize.And the spray equipment in the present embodiment has adopted fabricated structure, can freely change nozzle according to cleaning requirement, improves cleaning efficiency, and it is convenient to change accessory.
The above; it only is the preferable embodiment of the utility model; but protection range of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement all should be encompassed within the protection range of the present utility model.Therefore, protection range of the present utility model should be as the criterion with the protection range of claims.
