Description

INSTALLING STRUCTURE OF FREQUENCY ELEMENT OF SUPERSONIC WAVES WASHER}

The present invention relates to an ultrasonic cleaner widely used in the semiconductor and general industrial fields, and more particularly to a vibration device installation structure of the ultrasonic cleaner.

Ultrasonic vibrating element constitutes a single frequency, and has been widely used in ultrasonic cleaners, plastic adhesives, fish detectors, and medical equipment.

In particular, the ultrasonic cleaner uses a vibration element of 28, 40, 50, 70, 100 KHz, and the vibration element has a circular and block shape, which causes mechanical resonance at a single frequency as described above.

The conventional single frequency method has a disadvantage in that ultrasonic waves are non-uniform in the cleaning tank and the output changes sensitively as the water depth fluctuates.

The present invention was devised to solve such a conventional problem, and an object of the present invention is to provide a complex vibration including longitudinal vibration and lateral vibration by installing two vibration elements having different frequencies in parallel instead of a single frequency of an existing vibration element. It is able to produce various ultrasonic waves at the same frequency, so that the output is uniform and the cleaning effect can be more exerted.

FIG. 1B is another embodiment of FIG. 1A

Figure 2 is a side configuration diagram showing the installation state of the vibrating element

3 is another application example of the ultrasonic cleaner according to the present invention

The main constitution of the present invention for achieving the above object is characterized in that the first and second vibrating elements (3,4) having a different frequency to each of the diaphragm (1) in order one by one fixed installation, The first and second vibrating elements 3 and 4 are formed on the diaphragm 1 side by side in a horizontal and vertical order, and the first and second vibrating elements 3 and 4 are arranged in the horizontal direction. Alternately forming second vibrating elements 3,4, and below the first and second vibrating elements 3,4 between the first and second vibrating elements 3,4 in the preceding row. It characterized in that formed continuously.

Other features and configurations other than those described above will be described below in conjunction with the accompanying drawings.

First, the vibrating element used in the present invention preferably uses a BLT vibrating element (bolt clamped langevin type transducer), that is, a bolt tightening lance square vibrator.

It is developed for high power and uses piezoelectric ceramic.

High-power piezoelectric ceramics have high sensitivity, high amplitude characteristics, and low power load and load variations. BLT vibration device utilizing this feature generates stable ultrasonic wave against temperature, pressure, power and load fluctuation.

As described below, the BLT vibration device used in the present invention may be fixed by bolts or by making a predetermined groove to be adhesively fixed without bolts to increase the strength of the vibration device to the maximum.

1A and 1B are planar state diagrams in which the vibrating element is installed on the diaphragm 1 according to the present invention, and FIG. 2 is a side view of the planar installation state of FIG. 1A.

As shown, the first vibrating element 3 and the second vibrating element 4 are provided side by side across the diaphragm 1.

In the case of FIG. 1A, elements are installed in line with each other horizontally and vertically, and in FIG. 1B, the elements are sandwiched between one column.

Then, if it is on the area of the same diaphragm 1 can be installed more denser than the example of FIG.

In the arrangement as shown in FIG. 1A, the output distribution is widely output. That is, it can be installed to be output in a small number widely, the distribution as shown in Figure 1b has the advantage that the output is strong because the vibration elements can be arranged more densely

The number of arrays of the vibration elements can be arranged differently depending on the capacity, that is, how many W the capacity is.

The fixing of the vibrating element inserts and fixes the bolt 2 to the diaphragm 1, and then sequentially couples the first vibrating element 3 and the second vibrating element 4 by screwing them.

Alternatively, a predetermined groove may be made to adhesively fix the vibrating element without a bolt to increase the strength of the vibrating element to the maximum.

The first vibrating element 3 uses a strong one, for example 28 KHz and the other second vibrating element 4 uses a weak one, for example 40 KHz.

28KHz has a strong output and 40KHz has the advantage of uniform washing.

Here, the object to be cleaned, i.e., the cleaning material is mainly solid, and since the solid is rigid, polarization (lateral wave) is generated in addition to the small wave (long wave). Transition from transverse to transverse waves causes longitudinal and transverse vibrations to occur simultaneously.

According to the above configuration, when power is supplied to the first and second vibrating elements 3 and 4, ultrasonic waves of different frequencies are generated to generate mechanical vibrations of different frequencies, thereby causing various frequency resonances in the vibrating unit to produce longitudinal waves and A strong ultrasonic wave having a constant vibration waveform of the shear wave is generated and transmitted to the cleaning tank, thereby producing a good cleaning effect on the cleaning object.

3 shows another embodiment according to the present invention.

In the present embodiment, another second cleaning tank 11 is formed in the cleaning tank 10.

The reason for this configuration is that when sulfuric acid or the like is directly washed into the cleaning tank 10 when the cleaning product is to be cleaned using a solvent such as sulfuric acid, the cleaning tank 10 is damaged. ), A transfer fluid such as water, etc. is added, and a second washing tank 11 made of a material resistant to sulfuric acid is separately prepared so that sulfuric acid or the like is immersed in the second washing tank 11 so as to be cleaned. The second cleaning bath 11 is preferably made of plastic such as Teflon.

In the present invention, since the output becomes stronger by using two different frequencies at the same time, indirect cleaning, that is, cleaning operations such as rust removal by putting other second cleaning tanks 11 into the cleaning tank 10 containing water or organic solvent. can do

According to the present invention as described above there is an advantage that can greatly increase the cleaning effect by the generation of a double frequency.

In addition, according to the present invention, there is an advantage that the ultrasonic waves are uniform in the cleaning tank and the output is uniformly distributed without significant change in the water depth fluctuation.

In addition, according to the present invention, there is an advantage that the washing can be performed even by making a double washing tank by a strong frequency, and thus, rust removal work can be easily performed with a strong acidic substance without damaging the raw washing tank.

In addition, according to the present invention, it is possible to generate multiple vibrations including longitudinal vibration and lateral vibration, so that various ultrasonic waves can be generated at the same frequency so that the output is uniform and the cleaning effect can be more exerted.
