Abstract

(57) [Summary] [Purpose] To provide a support for an object to be cleaned that can reliably and easily drain the object to be cleaned. Constitution: A net plate 6 having an angle of 5 to 20 degrees with respect to a horizontal portion of a pedestal 4 of an object-to-be-cleaned support having a base metal plate as an object to be cleaned 14, and a net plate 6 to be cleaned in parallel with the net plate. It is composed of a plurality of round bar partitions 8 and 10 having a gap wider than the object to be cleaned and narrower than two objects to be cleaned.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a support for an object to be cleaned of a cleaning device having an easy draining table.

[0002]

2. Description of the Related Art An object to be cleaned is immersed in a cleaning tank filled with a cleaning solution such as water, an alkaline solution, an organic solvent, etc., and cleaned by ultrasonic irradiation, stirring, heating or the like. The object to be cleaned, which has been conventionally cleaned in this manner, is lifted from the cleaning liquid, rinsed with a rinse liquid, and then directly dried with hot air or vacuum.

[0003]

However, in the conventional cleaning device, the objects to be cleaned are put into the cleaning basket or the basket for the barrel for cleaning, and therefore, the portions where the objects to be cleaned are overlapped at the time of drying are the cleaning liquid or the rinsing liquid. Was difficult to dry due to the surface tension, which was a factor causing stains. In particular, when the object to be cleaned is a metal plate such as copper, iron or aluminum used for a power semiconductor module or the like, the objects to be cleaned are likely to overlap with each other and stains often occur. Therefore, to prevent the objects to be cleaned of multiple metal plates from coming into contact with each other, install a plurality of partition bars and a mesh basket or a support in the basket at the bottom, and set the objects to be cleaned of metal plates between the partition bars. It is washed and dried after washing.

However, since the basket or the support provided with the partition bar is set horizontally, the liquid adhering to the metal plate adheres to a large area under the metal plate, so that the liquid draining is insufficient and the cleaning liquid or the rinsing liquid is used. Blots were easy to occur. In particular, when vacuum-dried, stains were often generated.

[0005]

In order to solve the above-mentioned problems, the present invention provides an object to be cleaned support of a cleaning apparatus having a base metal plate as an object to be cleaned, in which the horizontal portion of the pedestal is 5 times.
Or a partition board composed of a net plate having an angle of 20 degrees and a plurality of round bars arranged in parallel with the net plate and having a gap wider than the object to be cleaned and narrower than two objects to be cleaned. Is.

Further, the partition table is coated with Teflon.

[0007]

The objects to be cleaned can be set one by one by the gap between the adjacent round bars on the partitioning table, and the objects to be cleaned can be washed and drained without overlapping. Further, the net plate is provided at an angle of 5 to 20 degrees with respect to the gantry, so that the cleaning liquid moves to the lowermost portion when the liquid is drained, so that the liquid is drained reliably.

Further, the cleaning liquid is repelled from the partition by Teflon processing of the partition to ensure reliable drainage.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to FIG. Reference numeral 2 denotes a support body for supporting an object to be cleaned, which is a base-shaped metal plate made of copper, iron, aluminum or the like used in a power semiconductor module or the like. Reference numeral 4 denotes a frame of the main body of the support, and the frame 4 has a mesh plate 6 having a gentle angle, for example, 5 to 20 degrees with respect to the horizontal portion 5 of the frame, and a mesh plate made of stainless steel in parallel with the mesh plate 6 mechanically A partitioning stand with a number of round rods of strong strength and thin side by side arranged in parallel
0 is set in two stages. The gap between the adjacent round bars is selected to be slightly wider than the thickness of the objects to be cleaned and narrower than the thickness of two sheets.

When cleaning the object to be cleaned, a gap 1 between the round bars forming the partitioning stands 8 and 10 and the adjacent round bars.
2, the object to be cleaned 14 of a metal plate is inserted, the object to be cleaned is set, and the object is immersed in a cleaning solution in a cleaning tank (not shown), and ultrasonic waves are applied.
Wash the washing solution by stirring and heating. When the support body is pulled up from the cleaning tank after cleaning, the cleaning liquid moves downward and drops through the mesh plate.

At this time, the cleaning liquid moves to the lowermost part of the object to be cleaned, so that the liquid is surely drained and stains are less likely to remain.
Further, since the areas to be cleaned and the objects to be cleaned are small without contact between the objects to be cleaned, drying is easy and stains are less likely to remain. In addition, since the partition table is formed of a round bar, it is less likely to damage the object to be cleaned when inserting and removing it from the support body.

In the above-mentioned embodiment, the partitioning base has two stages, but it is difficult to support the object to be cleaned, but one stage may be used. Further, it is economically disadvantageous, but the number of stages may be three or more. If the angle of the mesh plate and the partition table with respect to the horizontal part of the gantry is large, the object to be cleaned is likely to roll, and if the angle is small, the drainage is poor and the range is selected to be 5 to 20 degrees. Also, if at least the partition of the partition and the mesh plate is made of Teflon, the cleaning liquid or the rinse liquid at the time of rinsing is repelled at the time of draining and surely drains in a short time and at the time of inserting the object to be cleaned into the support body. Also, the object to be cleaned is not damaged when taken out. The partitions 8 and 10 may be round bars such as ellipses or cylindrical bars.

[0013]

According to the present invention, the objects to be cleaned are set without overlapping with each other, so that the liquid draining after cleaning and rinsing the objects to be cleaned can be reliably and easily performed. Moreover, the object to be cleaned is not damaged.
