Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of use] The present invention relates to a rack for holding a cleaning object and immersing it in a cleaning liquid when cleaning the surface of a plate-shaped cleaning object.

[Prior Art] Generally, as a method for cleaning the surface of a plate-shaped product, ultrasonic cleaning in which ultrasonic waves are used for cleaning is known. In this ultrasonic cleaning, a rack as shown in FIG. 2 is used to hold the plate-shaped cleaning product. This rack has 4
A frame 1 composed of vertically extending members, side plates 2 and 2 attached to the lower end of the frame 1, and two support bars 3 and 3 installed between the side plates 2 and 2. ,
The frame 1 is provided with two guides 4, 4 ... In this cleaning rack, a plurality of grooves 5 provided on the outer circumference of the guides 4, 4, ... Hold both sides of the plate-like cleaning object 7 to be cleaned. Then, the rack is suspended by the supporting shafts 7, 7 erected on the upper end of the frame 1, and the plate-like cleaning product 6 is immersed in a cleaning liquid having a strong high-frequency sound field of 20 kHz to 100 kHz. As a result, by utilizing the continuous cavitation phenomenon that occurs on the surface, the foreign matter adhered to the fine recesses on the solid surface is peeled off into the liquid and washed. Thereafter, necessary post-treatment is performed so that the removed foreign matter does not reattach to the surface of the washed product.

In this post-treatment step, for example, a method is known in which a plate-like washed product is washed with a washing liquid such as CFC, ethanol-based, IPA-based, and warm pure water. At that time, the CFC, ethanol, and IPA-based cleaning liquids are easily vaporized, and their surface tension is weak, so that water drainage and evaporation rate are fast, and stains and spots are less likely to remain on the surface after drying the plate-like washed product.

[Problems to be solved by the invention] However, in the case of hot pure water, it is more difficult to vaporize than the above-mentioned cleaning liquid, its surface tension is strong, and water depletion and evaporation rate are slow, so that stains may appear on the surface of the plate-like washed product after drying. And spots remain. In particular, the ripples on the liquid surface at the time of draining were a major cause of spots and spots on the surface after the cleaning.

In recent years, the use of chlorofluorocarbon-based cleaning liquids has resulted in the depletion of the earth's ozone layer, and the ethanol-based and IPA-based cleaning liquids have become a social problem due to their flammability. It has been reviewed and attracted attention. To spread this cleaning method using warm pure water, it is necessary to solve the above problems.

Therefore, in the present invention, in view of the above problems in the conventional art,
It is an object of the present invention to provide a rack for washing plate-like parts, which is unlikely to be vaporized like pure water and has a surface tension that makes it difficult for stains or spots to form on the surface when the plate-like wash is washed. To aim.

[Means for Solving the Problem] That is, in order to achieve the above object, according to the present invention, a plurality of plates including a frame and at least a pair of guides provided on the frame and having grooves formed at regular intervals are provided. For cleaning plate-shaped parts, in which the above-mentioned grooved guides are attached to be inclined vertically, in a rack for cleaning plate-shaped parts in which cleaning objects are immersed in a cleaning liquid while being held parallel by the guides at regular intervals. Providing a rack.

[Function] Rippling on the surface of pure water occurs when the cleaning rack is lifted up from the cleaning liquid by the grooved guide temporarily pulling the cleaning liquid by surface tension. At this time, the entire plate-like washed product has not yet been lifted up from the pure water, so that traces of this wave remain on the surface of the washed product and remain as spots or spots.

In the rack for cleaning plate-shaped parts according to the present invention, the grooved guide is installed so as to be inclined vertically with respect to the liquid surface of the cleaning liquid. As a result, when the grooved guide is pulled up from the cleaning liquid, the surface of the cleaning liquid is gradually pulled out from the pure water surface without being pulled by the surface tension at a time, so that the ripple of the cleaning liquid on the liquid surface is suppressed. . As a result, traces of waves do not remain on the surface of the washed product, and stains and spots are less likely to occur.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows an embodiment of a rack for washing plate-like parts according to the present invention. This plate-like component cleaning rack is provided with a frame 10 formed by four vertically extending members, side plates 20 and 20 attached to the lower ends of the frame 10, and a lower part of both side plates 20 and 20. Lower two support rods
30, 30, side plates 20, 20 are provided with two guides 40, 40 ... A plurality of grooves 60 for sandwiching and holding the plate-like cleaning object 50 to be cleaned are provided at regular intervals on the peripheral surfaces of the guides 40, 40 ... These points are substantially the same as the conventional wave cleaning rack.

In the present invention, the guides 40, 40 ... Are installed so as to be inclined with respect to the liquid surface of the cleaning liquid, that is, the horizontal surface. That is, the frame 10 is composed of four vertical members, and since the frame 10 is immersed in the cleaning liquid in a state of standing upright almost vertically, the guides 40, 40 are installed obliquely with respect to the frame 10. There is. Also this guide
Of the 40, 40 ..., the mounting position of the lower end of the lower guide 40, 40 is almost the same as the height of the supporting bars 30, 30 mounted on the lower side of the both side plates 20, 20. It is installed in.

In the rack for cleaning plate-shaped parts described above, the guide 40,
Both sides of the plate-shaped cleaning product 50 are held in the grooves 60 of 40, and the lower ends thereof are placed on the supporting rods 30, 30 to hold a plurality of the plate-shaped cleaning products 50 arranged in parallel in the vertical direction. And frame 10,
A rack for washing plate-like parts is hung by the supporting shafts 70, 70 attached to the upper end of 10 ...
Immerse in a cleaning solution in the presence of a strong high-frequency sound field of ~ 100kHz to clean. After that, when the plate-shaped part cleaning rack is lifted from the warm pure water, the guides 40, 40 ... cut the cleaning liquid's liquid surface at an angle, so that the surface tension does not pull the cleaning liquid's liquid surface at a time, and gradually it is pulled from there. Be raised to. As a result, ripples on the surface of the cleaning liquid are suppressed,
No traces of waves are left on the surface of the item to be washed, and there are no spots or spots.

Further, in the above-mentioned embodiment, since the mounting positions of the lower ends of the lower guides 40, 40 are arranged at substantially the same height as the height of the support bars 30, 30, finally, the lower guides 40, 40 are attached. ,
When the lower end of the 40 is completely removed from the surface of the cleaning liquid, the plate-like cleaning material 50 has already escaped from the surface of the cleaning liquid even if the cleaning liquid is ruffled, and the surface has marks or spots of waves. It doesn't.

[Effects of the Invention] As is clear from the above description, by using the rack for cleaning plate-shaped parts according to the present invention, a cleaning liquid such as pure water that is relatively hard to vaporize and has a high surface tension is used. When washed by washing, no stains or spots are left on the surface of the plate-like washed product. Therefore, the effect that the cleaning with such a cleaning liquid can be easily performed is obtained.
