BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for washing and cleaning residual components such as a plating solution adhering on a processed work panel.

[0002]

2. Description of the Related Art Generally, when cleaning a work panel such as a PC board which has been subjected to a plating treatment, cleaning tanks are arranged in two or three stages, clean water is supplied from a final stage, and the cleaning water is supplied. Wow
In most cases, the so-called countercurrent method is used, in which the second tank and the first tank are flowed in the order opposite to the direction of the panel processing. As another method, there is a spray method in which cleaning water is sprayed from a nozzle and sprayed onto a work panel to perform cleaning.

[0003]

The above-described counter-current cleaning is an excellent method for efficiently cleaning a large amount of work panels in a short time, but a large amount of water is required for more complete cleaning. Must be countercurrently flowed, thus increasing the amount of water consumption and consequently the amount of drainage. In addition, since two or three washing tanks are usually installed, the equipment cost increases and the installation area of the apparatus increases.

[0004] On the other hand, the spray method is excellent as a method for performing stable washing, and requires a small installation space because the amount of water used is small and the apparatus is compact. Has a problem.

Accordingly, it is an object of the present invention to quickly and efficiently treat a larger number of panels, and particularly to achieve a high cleaning effect with a small amount of cleaning water even for a complicated shape. An object of the present invention is to provide a washing and cleaning apparatus which can be made and requires a small installation area of the apparatus.

SUMMARY OF THE INVENTION An object of the present invention is to provide an apparatus for washing residual components such as a plating solution adhering on a processed work panel by washing with water, wherein the apparatus is filled with washing water for washing by immersing the panel . A washing tank with a tank width somewhat larger than the panel thickness, a rack for inserting the panel into the washing tank and pulling it up from the washing tank, and a washing tank arranged at the top of the washing tank so as to sandwich the panel from both sides without contact. A nozzle for jetting washing water that jets fresh washing water to wash both sides of the panel when the panel washed with the washing water in the tank is pulled out of the washing tank,
An air pipe arranged at the lower part of the washing tank to discharge air for stirring the washing liquid in the washing tank and a discharge pipe arranged at the bottom of the washing tank to discharge the same amount of washing water jetted from the washing water jet nozzle. This has been achieved by a cleaning device characterized by having:

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view showing an embodiment of a washing and cleaning apparatus according to the present invention. FIG. 1 shows a cross section of the washing and washing apparatus according to the present invention. The apparatus comprises a washing tank 1, an outer peripheral tank 2 surrounding the washing tank, a washing water jet nozzle 4 arranged so as to sandwich a work panel 3 on the upper part of the washing tank from both sides without contact, and a lower part of the washing tank. And a drain pipe 6 arranged at the bottom of the washing tank. First, the panel 3 supported by the rack is inserted from the upper part of the washing tank 1 filled with a minimum amount of washing water necessary for washing the panel, and immersed in the washing water. The air is discharged from the air pipe 5 arranged in the cleaning section and the washing is performed while stirring. While slowly lifting the panel after washing from the washing tank,
Nozzles 4 for jetting washing water arranged on both sides of the upper part of the washing tank
Then, a predetermined amount of washing water is sprayed onto the panel to perform finish washing. At the same time that the cleaning water is sprayed from the nozzle, the cleaning liquid is discharged from the drainage pipe 6 arranged at the bottom of the cleaning tank at substantially the same amount as the cleaning water sprayed from the nozzle, so that the liquid level in the cleaning tank is kept constant. To

[0008]

[Effects of the Invention] With the water washing and cleaning apparatus of the present invention, more panels can be processed quickly and efficiently, and in particular, a high washing effect can be achieved with a small amount of washing water even for a complicated shape. I can do it. Further, since the apparatus of the present invention is significantly smaller, the installation area of the apparatus is smaller than that of the conventional cleaning apparatus. Another advantage is that the amount of cleaning liquid that is discharged is significantly reduced compared to the conventional method, so that the disposal cost of waste liquid is reduced, and even when plating solution is recovered, it can be recovered at lower cost. You can do it.
