2. Description of the Related Art As shown in FIG. 7, a conventional ultrasonic cleaning apparatus is a hatch system in which an object to be cleaned (hereinafter referred to as a work) is immersed in a fluid filled in a tank. . Therefore, there are the following problems. That is, since the work is moved horizontally and vertically, and immersed in the tank, the transfer device and operation become complicated, or the transfer takes time, the installation space is expanded, and the factory is enlarged. And so on.

On the other hand, in the case of a flat work (for example, a glass, a liquid crystal plate, or the like), the work is usually conveyed using a chain conveyance and a guide member. Accordingly, there are problems such as traces of the kite member remaining on the work, which may cause defective products, necessitate post-processing, and lower efficiency.

Embodiments of the present invention will be described below.

The work carried in by the carry-in side conveyor is supported or accommodated (hereinafter referred to as a support) by a washing frame or a basket (illustrated example) supporting member moving along the rail, and the basket is Using the wheels and moving means such as wheels, moving members, moving rods, and moving arms, and the rails, the work that has been moved and accommodated (input) in this basket is directed to the first outer tank. To be positioned above the lower part of the inner tank in the outer tank. Then, at the stage where the upper part of the inner tank is lowered and coincides with the lower part of the inner tank (the inner tank is formed by matching), the fluid (cleaning liquid) is sequentially supplied (the cleaning liquid may be supplied to the lower part of the inner tank in advance. ). Then, when the upper portion of the inner tank is filled with the cleaning liquid, the ultrasonic generator is operated to remove the dirt from the work using the ultrasonic vibration energy. If an ultrasonic generator is provided also in the upper part of the inner tank, more efficient cleaning can be achieved. Ordinarily, the cleaning liquid is overflowed from the upper portion of the inner tank, flows down into the outer tank, and the floating dirt is caused to flow down at the same time.

When the cleaning of the work is completed by the above-described operation, the cleaning liquid in the upper and lower parts of the inner tank and the outer tank is returned to the fluid storage tank (washing liquid storage tank) through the filter. This downfall
At the stage where the (drainage) action is performed sequentially (it may be used together from the beginning), the upper part of the inner tank is moved upward. At approximately the same time as or when this movement is completed, drainage and the like are completed, and the first cleaning is completed.

Next, the operation proceeds to rinse cleaning. When the cleaned work reaches the next lower part of the inner tank by the same operation as described above, the lower part of the inner tank is matched with the upper part of the inner tank. When the rinse water is filled from the rinse storage tank to the upper part of the inner tank via the phone and the filter, the ultrasonic generator is operated,
Uses ultrasonic vibration energy to remove dirt from the workpiece.
In addition, if an ultrasonic generator is provided in combination or individually on the upper portion of the inner tank, the side surface of the inner tank, or the like, more efficient rinsing can be achieved. Normally, the rinse water is overflowed from the upper part of the inner tank and flows down into the outer tank, so that the remaining cleaning liquid and dirt or the dirt of the rinse water are simultaneously flowed down.

When the rinsing of the work is completed by the above operation, the rinsing water in the upper and lower parts of the inner tank and the outer tank is returned to the rinsing storage tank through the filter. Stages in which this flow (drainage) action is performed sequentially (may be used together from the beginning)
Then, the upper part of the inner tank is moved upward. At substantially the same time as or when this movement is completed, drainage and the like are completed, and the rinse cleaning is completed.

Further, various processes are performed on the rinsed work through the same operations and operations as described above.

Thereafter, when the next zone is reached, the processed work is usually dried by hot air through a hot air means and a fan.

The dried and cleaned work reaches the completion zone via the conveying means.
