Description
Technical field
The present invention relates to ultrasonic cleaning technology fields.
Background technique
Ultrasonic wave has good rectilinear propagation properties, and the ultrasonic wave that irradiation comes up from bottom is most of by horizontal plane
It is reflected back in cleaning solution, ultrasonic wave identical with two downward beam frequencies meets vertically upward, when compact part is just superimposed with part of rarefaction
When, it cancels out each other, generates standing wave, and lose cleaning force.Existing ultrasonic cleaning technology is dispersed in cleaning due to the presence of standing wave
Dirt in liquid condenses upon at node due to being made power by ultra sonic machinery power, causes dirt accumulation, cannot be scattered in liquid phase
In, leverage clean rate.If standing wave node can stick in cleaned work close to cleaned workpiece surface, the dirt of accumulation
On part surface, and under the TRANSIENT HIGH TEMPERATURE environment caused by the cavitation nuclear disruption of periphery, penetrated deep into cleaned inside workpiece, shape
At irreversible permanent spot, or even cause economic loss.On the other hand, ultrasonic cavitation core is always grown in negative pressuren zone,
It is collapsed in zone of positive pressure, causes the cleaning force uneven distribution between positive and negative pressure area, thus generate color in cleaned workpiece surface
Difference, local surfaces are deteriorated because of overclean, other local surfaces influence cleanliness because cleaning is insufficient.Ultrasonic cleaning
Technology is due in the presence of the above both sides defect, it is difficult to guarantee cleaning uniformity, cause clean rate lower, the degree of automation is not
It is high.The method that existing cleaning technique mostly uses rotation or lifts cleaned workpiece changes the space-time position of cleaned workpiece to keep away
The problem of opening standing wave node, not can effectively solve standing wave node accumulation dirt.
Summary of the invention
The present invention provides a kind of method and device for improving ultrasonic cleansing rate, it is intended to by manufacturing liquid on cleaning solution surface
Surface wave wave reduces the generation of standing wave node, and dynamic changes the space-time position of node, eliminates the dirt accumulation generated by standing wave
Phenomenon mentions high-detergency, while dynamic changes the space-time position of cavitation nuclear disruption, improves the uniformity of ultrasonic cleaning, shortens
Scavenging period, reduction are deteriorated.
The present invention provides a kind of ultrasonic cleaning equipment, and described device includes: rinse bath (1), ultrasonic generator
(2), unrestrained device (3) are made.
The present invention further provides a kind of method for suppersonic cleaning, is cleaned using above-mentioned ultrasonic cleaning equipment,
It the described method comprises the following steps:
Workpiece to be cleaned is placed in rinse bath (1) by step 1；
Step 2 injects cleaning solution to rinse bath (1), until submerging workpiece to be cleaned；
Step 3 opens ultrasonic generator (2) to cleaning solution and applies ultrasound field；
Step 4 makes unrestrained device (3) manufacture liquid level wave with the unlatching of step San Tong method.
In conclusion using above technical scheme, the present invention is at least had the following beneficial effects:
One, dirt accumulation phenomenon is eliminated, high-detergency is mentioned
By manufacturing liquid level wave, the form on cleaning solution surface is changed, becomes uniform plane configuration as wavy curved form
State, with the ups and downs of unrestrained wave, the reflection behavior of surface of cleaning solution becomes diffusing reflection, vertical directive liquid level by mirror-reflection
Ultrasonic wave no longer reflected back by former road, but as the variation of wave curved surface is scattered to from all directions, thus greatly
It is superimposed and generate the probability of standing wave to reduce frequency is identical, contrary two beam ultrasonic waves, the two beams ultrasound occurred once in a while
The node that the amplitude that the compact part and part of rarefaction of wave are superimposed and generate is zero, also because wherein a branch of ultrasonic wave is dissipated by liquid level wave
It is emitted back towards and, it is indefinite that the space-time position of direction and compact part and part of rarefaction all converts, therefore the node generated once in a while is also in space-time
Up conversion is indefinite, cause dirt in cleaning solution can not aggregately stacked, can be scattered in cleaning solution, greatly improve well
Ultrasonic cleansing rate.
Two, cleaning speed is improved, scavenging period is shortened, reduces energy consumption
By the irreflexive ultrasonic wave of liquid surface wave wave, only 1/180 is vertically reflected, and is overlapped mutually with the former ultrasonic wave of injection
Standing wave is generated, the overwhelming majority is sideling reflected back cleaning solution, cleaning workpiece twice work doing is treated, equivalent to increase one second
Ultrasound source just compensates for the deficiency that the workpiece in the first ultrasound source shadow region cannot be cleaned effectively, improves clear
Speed is washed, scavenging period is shortened, reduces energy consumption.
Three, improve cleaning uniformity
Ultrasonic cleaning is mainly to utilize the cavitation of ultrasonic wave, and cavitation nucleus is drawn high power growth in negative pressuren zone (part of rarefaction),
And be squeezed power in zone of positive pressure (compact part) and be closed, so cavitation nuclear disruption only occurs in a certain time point of zone of positive pressure (compact part)
Position, therefore the relative distance of two adjacent vacant nuclear disruptions is approximately equal to the distance of two adjacent compact parts, that is, is equal to ultrasonic wavelength.By
In the centre of two adjacent compact parts there are one part of rarefaction, which can become compact part in next cycle and generate collapsing for cavitation nucleus
It bursts, so the distance of two adjacent vacant cores of alternation collapse is half wavelength (λ/2).It follows that the time point of cavitation nuclear disruption
Position is the integral multiple apart from ultrasound source λ/2, when the position of ultrasound source immobilizes, the space-time position of cavitation nuclear disruption
It is to stay to stand motionless (not flowing assuming that homogeneous cleaning solution is static), the strong and weak position of this ultrasonic cleaning power immobilizes just
Cleaning force uneven distribution is caused, and this uneven distribution is far apart, with common 28KHZ ultrasonic wave, aqueous clear
For washing lotion (C=1450m/s), λ/2=C/2f=1450/2*28000=0.026m=2.6cm.Just because of ultrasonic cleaning power
Uneven distribution, and strong and weak position is apart from each other, thus be easy to generate color difference in cleaned workpiece surface, local surfaces are because of cleaning
Excessively deteriorate, other local surfaces influence cleanliness because cleaning is insufficient.The present invention manufactures liquid level on cleaning solution surface
Wave, peaks and troughs generate upward pulling force and downward pressure to cleaning solution respectively, until making the density of cleaning solution vertical
Density alternation occurs on direction, causes ultrasonic propagation velocity C speed alternation, by formula f=C/ λ it is found that frequency f is constant normal
Number, speed C alternation cause wavelength X alternation, so that the time point position of cavitation nuclear disruption be made accordingly to generate upper and lower displacement, expand most
The sphere of action of strong impact force improves cleaning uniformity.In addition, when more than two workpiece are cleaned simultaneously, from workpiece one
The ultrasonic wave reflected back is possible to generate standing wave on two surface of workpiece, forms dirt accumulation, if applying the present invention,
Can solve this problem, alternately variation causes the space-time position of ultrasonic wave compact part and part of rarefaction also checker to wavelength X, thus
It can not be formed to stay and found motionless node, eliminate standing wave influence, this is multiple for cleaning a large amount of small workpieces or surface shape simultaneously
Miscellaneous changeable workpiece is particularly effective.
The invention will be further described combined with specific embodiments below, but not as a limitation of the invention.
