Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ultrasonic cleaning tank used in an automatic ultrasonic cleaning apparatus, and in particular, it is desired to perform cleaning by exerting an ultrasonic cleaning effect on the entire surface of a cleaning member having high cleanliness. It relates to a cleaning tank structure.

2. Description of the Related Art FIG. 2 shows an ultrasonic cleaning tank used in a conventional automatic cleaning apparatus, in which an oscillator is provided at a lower portion and a side surface portion.

As shown in the figure, the oscillator 12 is installed under the cleaning tank having the cleaning tank 15 on the base 1, the work die 16 is mounted on the oscillator 12, and the oscillator 13 is installed on the side surface of the tank.
In the cleaning of the cleaning member 7 by the ultrasonic cleaning tank as described above in which the cleaning liquid 10 is sufficiently immersed in the workpiece 7 and the oscillator 13, the cleaning member 7 conveyed by the conveying arm 8 is below the conveying arm 8. The cleaning member 7 is set in the work die 16 by the lateral movement a and the descending movement b after being inserted into the tank by the direction movement b.
The ultrasonic cleaning process is performed.

In the cleaning by such a cleaning tank structure, there is a portion where ultrasonic waves are not directly oscillated on the entire surface of the cleaning member 7, that is, the cleaning effect on the upper surface of the cleaning member 7 is small and therefore sufficient cleaning is achieved. Therefore, it is necessary to invert the cleaning member 7. Therefore, a reversing mechanism is installed, or the cleaning member 7 is taken out, inverted and re-cleaned. Therefore, there is a problem that the tank structure becomes complicated or the cleaning time becomes long. .

[0005]

In order to oscillate ultrasonic waves on the entire surface of the cleaning member, it is possible to oscillate from the upper side, which is particularly difficult, and to prevent the oscillators from affecting each other. Therefore, the oscillators are placed in the tank without facing each other to achieve six-sided oscillation.

[0006]

In order to directly oscillate ultrasonic waves on the entire surface of the cleaning member, it is necessary to install an ultrasonic oscillator above the tank so as to oscillate ultrasonic waves on the upper surface of the cleaning member. The upper part is the inlet of the cleaning member, and the oscillating part must be submerged in the liquid to protect the oscillator. Installs an oscillator from the top, puts the oscillating part in the liquid, inserts the cleaning member in the tank in the right area and inserts the cleaning member into the tank, and then laterally moves to the left, enabling ultrasonic cleaning by upper oscillation. And

Ultrasonic oscillators are installed in the upper, left and rear parts of the two synchronized cleaning tanks A, and cleaning members are inserted from the carry-in port of tank A and laterally moved to the left in the tank. Then, ultrasonic waves are directly oscillated on the upper surface, the left side surface and the rear surface of the cleaning member. Next, the cleaning member is carried into the tank B by the carrier, but in the tank B, the ultrasonic oscillator is at the bottom of the tank. , The right side and the front side are installed. Therefore, the horizontal movement to the left in tank B causes the remaining three surfaces that were not directly oscillated in tank A, namely, the bottom surface, right surface, and front surface direct ultrasonic waves to be oscillated. As a result, it is possible to perform strong ultrasonic cleaning on the entire surface of the cleaning member by going from tank A to tank B.

Since the ultrasonic oscillator installed above is submerged in liquid, the oscillator is sufficiently protected.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows an ultrasonic cleaning tank of the present invention.
The two-tank type omnidirectional ultrasonic oscillator tank structure in which three ultrasonic oscillators are installed in each of tanks B and B is shown.

From the figure, the cleaning tank 2 and the cleaning tank 3 are mounted on the base 1.
There is. An ultrasonic oscillator is installed in the upper part 4, the left side surface part 5, and the rear surface part 6 on the left side of the carry-in port of the cleaning tank 2, and similarly in the cleaning tank 3, the ultrasonic oscillator is installed in the lower part of the tank. 12, the right side surface portion 13 and the front surface portion 14, respectively, and the work dies 9 and 11 are located at the bottoms of the tanks in the left direction of the inlet, and the cleaning liquid 10 is the oscillation surface of the upper surface ultrasonic oscillator. Keeps the liquid level at which is in the liquid.

In the cleaning using the ultrasonic cleaning tank structure as described above, first, the cleaning member 7 is transferred to the cleaning tank 2 and the transfer arm 8 is installed.
When it is carried in and set on the work die 9 by the horizontal movement a and the vertical movement b, the cleaning is performed on the upper surface, the left side surface, and the rear surface of the cleaning member 7 with the ultrasonic waves having a high ultrasonic effect.

Next, the cleaning member 7 is set from the cleaning tank 2 to the work die 11 of the cleaning tank 3 by operations such as vertical movement b and lateral movement a of the transfer arm 8. In the cleaning tank 3, ultrasonic waves that go straight ahead in the previous tank. Ultrasonic cleaning with straight waves is performed on the surface that has not been subjected to the cleaning, that is, the lower surface of the cleaning member, the right side surface, and the front surface.

As a result of the above cleaning treatment, the cleaning by the ultrasonic cleaning tank of the present invention enables strong ultrasonic cleaning of the entire surface of the cleaning member 7, which is the six surfaces of the member.

[0014]

EFFECTS OF THE INVENTION By simultaneously oscillating ultrasonic waves from three directions in the tank, (1) three times the ultrasonic sound pressure is obtained and the cleaning power is increased.

(2) The ultrasonic sound pressure distribution becomes uniform due to the total oscillation in three directions.

(3) The six surfaces can be washed strongly in two tanks, and the space required for the device is small.
