Abstract
The utility model relates to a kind of circuit board cleaning device, comprise: casing, be positioned at least two remover liquid nozzles of box house, and be positioned at the gas blow pipe of bottom half and the pressure regulator valve being connected with gas blow pipe, and on gas blow pipe, be provided with at least two bubbles generation holes.The utlity model has good cleaning performance.
Description
Technical field
The utility model relates to PCB cleaning machine, specifically, relates to a kind of circuit board cleaning device.
Background technology
It is extremely important link in precise electronic assembling that circuit board cleans, and main purpose is to wash the scaling powder on circuit board that remains in producing in soldering process.
Jet flow cleaning is one of common cleaning, and jet flow cleaning is that cleaning fluid is pressurizeed with high-pressure pump, then sprays from nozzle, and high-pressure spray is sprayed onto on circuit board, thereby washes out welding assisted agent residuals.
Be illustrated in figure 1 existing jet cleaning device structural representation, polylith circuit board 4 is placed in casing 1, in casing 1 inside, fluid injector 2 and 3 is installed, and in fluid injector 2 and 3, the cleaning fluid of ejection is realized the cleaning to circuit board 4.
But there is following shortcoming in jet flow cleaning: if circuit board is put comparatively intensive and put for multilayer, liquid jet meeting crested, causes effluxvelocity to lower, and then cause the circuit board position of crested not wash clean clearly.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of low cost and can effectively improves the circuit board cleaning device of cleaning performance.
This circuit board cleaning device, comprising: casing, is positioned at least two remover liquid nozzles of box house, and is positioned at the gas blow pipe of bottom half and the pressure regulator valve being connected with gas blow pipe, and on gas blow pipe, be provided with at least two bubbles generation holes.
Further, the number of described remover liquid nozzle is two, and described two remover liquid nozzles lay respectively at the both sides of box house.
Further, this circuit board cleaning device also comprises at least one circuit board of piling up between described two remover liquid nozzles.
Further, described gas blow pipe is positioned at the below of described circuit board.
Further, the opening direction that hole occurs the bubble on described gas blow pipe is for facing toward the direction of described circuit board.
The disclosed circuit board cleaning device of the utility model has solved in high density and has piled up the not good enough problem of cleaning yield in circuit board situation, and simple in structure, and reliability is strong, is easy to safeguard.
Accompanying drawing explanation
Fig. 1 is existing jet cleaning device schematic diagram;
Fig. 2 is cleaning device the first schematic diagram described in the utility model;
Fig. 3 is cleaning device the second schematic diagram described in the utility model.
The specific embodiment
Describe according to the circuit board cleaning device of the utility model realization below with reference to accompanying drawings and by embodiment.In the following description, many details have been set forth to make person of ordinary skill in the field more fully understand the utility model.But, for the technical staff in affiliated technical field, being apparent that, realization of the present utility model can not have some in these details.In addition, should be understood that, the utility model is not limited to introduced specific embodiment.On the contrary, can consider to implement the utility model by feature below and any combination of key element, and no matter whether they relate to different embodiment.Therefore, use for illustrative purposes only of aspect below, feature, embodiment and advantage and should not be counted as key element or the restriction of claim, unless clearly proposed in the claims.
Fig. 2 is cleaning device the first schematic diagram described in the utility model, and as shown in Figure 2, circuit board cleaning device described in the utility model comprises casing 1; Be positioned at least two remover liquid nozzles of casing 1 inside, i.e. remover liquid nozzle 2 and remover liquid nozzle 3; And be positioned at the gas blow pipe 5 of described casing 1 bottom and the pressure regulator valve 6 being connected with gas blow pipe 5; In addition, be also provided with at least two bubbles hole 7 occurs on described gas blow pipe 5, in Fig. 2, the number that hole occurs bubble is 4.Wherein, remover liquid nozzle 2 and remover liquid nozzle 3 are used for spraying cleaning fluid to the thing to be cleaned of putting in casing 1 is cleaned, gas blow pipe 5 is used for transmitting gas pressure, then there are hole 7 generations by a plurality of bubbles that arrange on gas blow pipe 5 in bubble, pressure regulator valve 6 is used for regulating the gas pressure in gas blow pipe 5, and then realizes the control that bubble is occurred to for hole 7 generation bubble numbers and speed.As shown in Figure 2, preferably, described remover liquid nozzle 2 and remover liquid nozzle 3 lay respectively at the both sides of casing 1 inside; At least one circuit board 4 is piled up between remover liquid nozzle 2 and remover liquid nozzle 3, is 4 circuit boards in this figure; And described gas blow pipe 5 is positioned at the below of described circuit board 4, the opening direction that hole 7 occurs the bubble on described gas blow pipe 5 is the direction facing to described circuit board 4, so that the bubble producing can be realized the cleaning to circuit board 4 by floating.Above-mentioned cleaning device, the acting in conjunction that the bubble of hole 7 generations occurs by remover liquid nozzle 2, remover liquid nozzle 3 and bubble realizes the high-efficiency washing to circuit board 4.
Fig. 3 is cleaning device the second schematic diagram described in the utility model, and this figure is the effect schematic diagram after Bubble formation.As shown in Figure 3, bubble 8 occurs to produce hole 7 from gas, and be positioned at the diverse location of circuit board 4, bubble 8 produces and agitates on the surface of circuit board 4, because bubble 8 very carefully can enter the inside that circuit board 4 is piled up layer, so can reach, more preferably clean effect under the cooperation of remover liquid nozzle 2 and remover liquid nozzle 3.
Although the utility model discloses as above with preferred embodiment, the utility model is not defined in this.Any those skilled in the art, various changes and the modification within not departing from spirit and scope of the present utility model, done, all should include in protection domain of the present utility model, and therefore protection domain of the present utility model should be as the criterion with claim limited range.
