Embodiment
Below in conjunction with drawings and Examples the present invention is described in detail.
As shown in Figure 2, the ultrasonic cleaning machine mainly is made up of ultrasonic generator 1, ultrasonic transducer 2 and rinse bath 3.When cleaning workpiece, cleaning fluid is put into rinse bath, in groove, act on ultrasound wave, cleaning fluid can adopt ss-25 motor cleaning fluid usually, or the cleaning fluid product of other type.After ultrasonic generator converts the alternating current of 50Hz to superaudio (such as 44KHz) electric oscillation signal, by output cable it is flowed to the ultrasonic transducer of bottom of rinse bath, be the superaudio mechanical vibration with superaudio electric oscillation conversion of signals and be emitted in the cleaning fluid by transducer.Rinse bath is the container that holds cleaning fluid and be cleaned object.It is smooth that the present invention gets surfacing, and the aluminium foil that thickness is tens microns is fixed on the framework, and its area size is decided according to measurement requirement.Immerse the aluminium foil level in the ultrasonic cleaning tank that clean-out system is housed and be fixed on a certain degree of depth.For comprehensive test cleaning performance, as shown in Figure 2, the placement location of aluminium foil 4 in rinse bath comprises horizontal positioned, vertical placement, the oblique 45 ° of placements in a left side and four kinds of modes of right oblique 45 ° of placements at least.
Behind the start certain hour, the phenomenon that can occur spot corrosion and then fragmentation when in the ultrasound wave sound field, being subjected to cavitation, comes off.Here fragmentation, this phenomenon that comes off are referred to as " corrosion ", it is different with the corrosion in the chemical reaction, is a kind of physical change process.The aluminium foil method of testing is simple, thereby can observe the power reflection cleaning performance quality of cavitation intuitively.The shortcoming of the method is that the thickness of aluminum foil material is not uniformly absolute, therefore can produce error to measurement result, this can solve by repeatedly measuring the method for averaging, and places the aluminium foil of multiple position and angle among the present invention in the rinse bath, is used for last averaged exactly.
For adopting the aluminium foil method of testing to obtain the aluminium foil test findings of different extent of corrosions, utilize the Matlab image processing techniques to quantize, calculate, mainly can draw corroded area ratio and two indexs of corrosion aperture distribution consistency degree of aluminium foil.
Corroded area is than the cavitation corrosion area that is meant every aluminium foil and the ratio of whole area, i.e. corroded area ratio, and the big more ultrasonic cavitation intensity that then illustrates of this ratio is strong more, thereby determines the influence degree of different parameters condition to ultrasonic cavitation intensity.
Corrosion aperture distribution consistency degree is meant whether the little pore size distribution of cavitation corrosion is even on every aluminium foil, represent uniformity coefficient with the variance of a plurality of small size corroded area ratios in the analysis, this variance is more little, illustrates that the ultrasonic intensity of each point in the ultrasonic cleaner distributes even more.
The present invention adopts Matlab software that the result that the aluminium foil method of testing obtains is carried out Flame Image Process, the method that replacement directly detects by an unaided eye, and it is more accurate credible that evaluation result is quantized.
As shown in Figure 3, the method for determining the corrosion aperture distribution consistency degree of aluminium foil comprises the steps:
(1) earlier the aluminium foil that is subjected to cavitation corrosion is carried out photosampling, obtain original image, it is smooth when taking pictures aluminium foil to be put, and avoids influencing the true area ratio;
(2) the Flame Image Process tool box (Image Processing Toolbox) by Matlab software carries out pre-service and area morphological analysis to image, and the area morphological analysis comprises gray processing, low-pass filtering, sharpening processing, binary conversion treatment, denoising processing;
(3) useful area with image is divided into a plurality of fritters, counts aluminium foil area A that erode or the corrosion fold at each small images
I1, and the area A of aluminium foil remainder
I2
(4) the cavitation corrosion area that calculates each fritter compares K
i=A
I1/ (A
I1+ A
I2);
(5) the cavitation corrosion area of obtaining all fritters compares K
iVariance as corrosion aperture distribution consistency degree.Among Fig. 3, S

S
b(j) be the black region area,
S
kTotal scan area when (t) being single pass, i.e. black and white region area sum.
Ultrasound wave is long more action time, and the aluminium foil corrosion degree is big more, for quantitative research ultrasonic cleaning effect rule over time, need carry out the time response experimental study.
The present invention places cleaning fluid with the aluminium foil of surfacing, smooth finish unanimity.Rinse liquid temperature is 30 ℃, and scavenging period is 30s, and cleaning frequency is 28KHz, when power is 20KW, and the aluminium foil test result that obtains.Then, when the scavenging period of this aluminium foil is 60s, 240s, the aluminium foil test result that obtains respectively.
Above-mentioned aluminium foil is placed in the rational background color, obtains and be beneficial to the image that utilizes the Matlab software analysis.Area evaluation method analysis result with the aluminium foil corrosion degree is as shown in table 1.
The time response experiment analysis results of table 1 ultrasonic cleaning effect
| Action time | 0 | 30 | 60 | 240 |
| The corroded area ratio | 0％ | 5.94％ | 11.24％ | 45.76％ |
The mode of action of ultrasonic frequency is improper can to form standing wave, makes the sound field intensity skewness in the cleaning fluid, thereby causes cleaning quality inhomogeneous.If the method that rests on a scientific basis for ultrasonic generator is provided with rational frequency sweep function, can be eliminated the influence of standing wave.Therefore, the present invention is on the 28kHz basis and other parameters (under the normal temperature and pressure in ultrasonic frequency, general power 4KW, cleaning fluid identity distance oscillator height 200mm, scavenging period 120s) to study the frequency effect mode respectively under the same terms be the aluminium foil testing experiment that frequency sweep, no frequency sweep are arranged.Area evaluation method analysis result with the aluminium foil corrosion degree is as shown in table 2.
The time response experiment analysis results of table 2 ultrasonic cleaning effect
| The frequency effect mode | No frequency sweep | Frequency sweep is arranged |
| The corroded area ratio | 25.84％ | 32.36％ |
| Corrosion aperture distribution consistency degree | 8.26％ | 1.44％ |
Can find out intuitively that from experimental result standing wave phenomena is obvious under the no frequency sweep condition, the aluminium foil test case is even under the frequency sweep condition, has effectively reduced standing wave phenomena.
Practice shows that higher rinse liquid temperature is more helpful to cleaning performance, still, temperature also should not increase simply, because the restriction of environment temperature and cleaning, equipment etc. in the cleaning process, and ss-25 cleaning fluid ratio is easier to volatilization, and the too high meeting of temperature causes disaster hidden-trouble.Experimental result proof when ultrasound wave is 180s action time is in cleaning process, and generally selected cleaning temperature remains 45 ℃.
The present invention proposes the aluminium foil method of testing of system and the area evaluation method of aluminium foil corrosion degree, the size that accounts for the total area with the aluminium foil lost area is estimated cavitation intensity, estimates the aperture distribution consistency degree with the variance of the corroded area ratio of a plurality of small sizes.Utilize the research that experimentizes of aluminium foil method of testing, finished the research of supersonic wave cleaning machine time response, designed the reasonable frequency mode of action, studied the temperature characterisitic of supersonic wave cleaning machine and realized the reasonable selection of cleaning temperature.The present invention can provide active data support and experimental verification for the performance parameter design of supersonic wave cleaning machine.
