Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to an ultrasonic electrolytic cleaning apparatus and method.

[0002]

2. Description of the Related Art Conventionally, a technique called ultrasonic electrolytic cleaning is a known technique as disclosed in, for example, Japanese Utility Model Laid-Open No. 5-81728, and is generally practiced.

[0003] In the ultrasonic electrolytic cleaning apparatus disclosed in the publication, as a means for cleaning metal products, degrease and rust are caused by a reduction reaction occurring on the surface of the object to be cleaned due to a potential difference between the two electrodes, and hydrogen gas generated is used. By using the effect of raising dirt in combination with ultrasonic waves, a higher cleaning effect is aimed at. In this case, as a method of electrically connecting the object to be cleaned with the cathode, a method of contacting the object to be cleaned with the cathode using a clip or the like has been adopted.

However, in the above-mentioned apparatus, when the means for connecting the object to be cleaned and the cathode is a clip or the like, each of the objects to be cleaned must be connected to the cathode. When the object to be cleaned has a shape (for example, a sphere) that is difficult to connect, there is a problem that the operation becomes extremely complicated.

In view of this point, the present applicant eliminates the need for the work of connecting the electrode and the object to be cleaned, and simply connects the object to be cleaned to the cleaning tank and electrically connects the object to be cleaned and the electrode. An ultrasonic electrolytic cleaning apparatus designed to be used is disclosed in Japanese Patent Application No. 7-172.
No. 22 (Japanese Patent Application Laid-Open No. 9-25600).
The proposed cleaning device functions as a cleaning tank containing an electrolytic cleaning liquid, and one or more objects to be cleaned, so that they can be electrically contacted and connected to one electrode to serve as one electrode body. And an electrode plate that is disposed so as to face the object to be cleaned on the network via the electrolytic cleaning liquid and that is connected to the other electrode and functions as the other electrode body. .

In the above-described cleaning apparatus, since the object to be cleaned simply sinks into the electrolytic cleaning solution and sinks in the electrolytic cleaning solution, and comes into electrical contact with the conductive mesh body. The ultrasonic electrolytic cleaning of the substrate can be performed, and the operation of connecting the object to be cleaned to the electrode body can be eliminated.

[0007]

However, in the ultrasonic electrolytic cleaning apparatus, a conductive mesh is placed in advance in a cleaning tank containing an electrolytic cleaning liquid, and an object to be cleaned is put into the cleaning tank during cleaning. Then, the electrode plate is placed in the cleaning tank so as to be positioned in the electrolytic cleaning solution above the object to be cleaned. Then, it is connected to a power source so that the conductive mesh and the electrode plate serve as a cathode and an anode, respectively, so that electrolytic cleaning can be performed.

Therefore, at the time of cleaning, the object to be cleaned is introduced from above the conductive mesh in the cleaning tank.
If the object to be cleaned is a small number of small parts, it is necessary to temporarily store the object to be cleaned in a separate storage container and transport it to the position of the cleaning tank. It is necessary to transfer the object to be cleaned before and after the cleaning work, for example, it is necessary to transfer the object to be cleaned onto a conductive net, and also to transfer the object to be cleaned after cleaning to a new storage container that is clean after cleaning. Work such as transfer has been troublesome.

In such a case, the conductive mesh can be used as a basket for cleaning and the basket can be used as a storage container for transporting an object to be cleaned. In this case, the conductive mesh is washed. Each time you need to connect it to a power source and generally use a strong clip,
This involved a cumbersome operation.

Since the upper surface 3a of the square rod body, which is the protruding part, is covered with a non-conductive insulating coating, the cleaning tank 2 is prevented from being charged, eliminating the danger of short-circuiting and eliminating unnecessary power consumption. Thus, power consumption can be reduced.

If it is slidable in the longitudinal direction, each square rod 47 can be moved in accordance with the shape and size of the mesh at the bottom of the washing basket, and the position of the projection abutting on the object to be washed can be adjusted. In the case of this configuration, for example, the distal end portion of the U-shaped main body 5 is made detachable to mount the guide support member 48 thereon.

Further, as shown in FIG. 9, for example, guide members 49 are provided around the U-shaped main body 5 when the washing basket is inserted, specifically, on the inclined surface 49a which spreads upward. When the guide member 49 is attached, the alignment between the mesh of the cleaning basket and the projection of the cathode electrode body is uniquely determined, so that there is no hindrance to the alignment in the electrolytic cleaning operation.

In the above-described ultrasonic electrolytic cleaning apparatus, the ultrasonic generating means 12 is disposed on the bottom side of the cleaning tank 2, but may be disposed on the side of the cleaning tank 2, as shown in FIG. The cathode connection cable 20 may be connected to the plate-shaped main body 51 on which a large number of projections 50 are implanted, and the surface of the projections may be treated with an insulating coating other than the upper surface. The projection 50 may be a column or a cone. Also, between each of the projections 50,
Holes penetrating vertically or grooves in the horizontal direction may be formed to enhance the fluidity of the cleaning liquid.
