DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a processing apparatus for degreasing and cleaning a workpiece, such as an electronic component, provided with small holes and blind holes, which is subjected to plating or plating.

[0002]

2. Description of the Related Art Conventionally, when a workpiece such as an electronic component, which is provided with small holes and blind holes, is subjected to a plating treatment or a degreasing cleaning performed prior to the plating treatment, the small small holes or blind holes are formed. When bubbles are attached, plating is not applied to the portion to which the bubbles are attached, or even when performing a degreasing cleaning process prior to performing the plating process, the cleaning solution does not enter the small holes / bag holes due to the bubbles, There is a problem that this part cannot be degreased and washed. As means for solving such inconveniences, there has been known a method in which a rotary container in which a work is placed is rotated, and the work is inverted in the rotary container to remove bubbles.

[0003]

[0008] However, simply reversing the workpiece rotating container is above mentioned can not be fully excluded bubbles defect remains. An object of the present invention is to provide a processing device that has solved such a problem .

[0004]

According to the present invention, in order to achieve the above object, an upper space formed in a processing tank configured to be able to be kept airtight by closing an entrance on the upper surface with a lid is connected to a vacuum pump. And a plating or cleaning treatment apparatus provided with a rotating container for accommodating a work provided in the treatment tank.
In the above, standing in the processing tank from the center bottom surface of the processing tank
A cylindrical body is provided, and at least a part of the cylindrical body is in contact with the inner surface thereof.
Into the drive unit provided outside the processing tank.
The rotating shaft that rotates in conjunction with the projection is projected into the processing tank,
The cylindrical part with a ceiling projecting upward from the bottom of the center of the rotating container
Fit the rotating shaft, and place the
The end is fixed . Such a configuration, especially
A cylindrical body that stands inside the processing tank from the center bottom surface of the processing tank is installed.
And at least partially contact the inner surface of the cylindrical body.
Insert and rotate in conjunction with a drive device outside the processing tank
The rotating shaft is projected into the processing tank,
Air does not enter the treatment tank through the
Thus, the rotating shaft can be projected into the processing tank.

[0005]

Embodiments of the present invention will be described with reference to the drawings. In the drawing, reference numeral 1 denotes a plating tank, and the plating tank 1 has an entrance 1a on an upper surface and a corrosion-resistant rubber packing 2a.
A vacuum pump 3 which is configured to be closed by a lid 2 provided with
And a barrel-type rotary container 4 for putting a work in the processing tank 1 is provided, and the rotary container 4 is rotated in conjunction with a driving device 5 provided outside the processing tank 1.

[0006] To explain this further, this processing tank 1
The lower end is fixedly supported on one slope of the mountain-shaped base 15.
The processing tank 1 is installed in an inclined state, and the upper end of the processing tank 1 is opened.
Cover 2 can be kept airtight by applying lid 2 to mouth 1a
At the same time, the upper space of the tank 1 is connected to a vacuum pump 3.
Was.

[0007] The treatment tank 1, the processing from the middle bottom surface
A cylinder 1b that stands up in the tank 1 is provided .
At least partly in contact with the surface
In conjunction with a motor 18 as a driving device provided outside the tank 1
The rotating shaft 16 is projected into the processing tank 1 and
Roofed cylindrical part 4b projecting upward from the center bottom surface of transfer container 4
The rotary shaft 16 is fitted to the
And the upper end of the rotating shaft 16 with the wing nut 17
Te, Ru mounting the rotary vessel 4 to the rotary shaft 16.

Reference numeral 19 denotes a metal connected to the anode electrode provided in the processing tank 1, reference numeral 20 denotes an electrode provided on the bottom surface of the rotary container 4, and the electrode 20 is connected to the cathode electrode 22 via the rotary shaft 16.
To be connected.

Although the treatment tank 1 for performing degreasing cleaning is not particularly shown, the one for performing electrolytic cleaning can use the treatment tanks of the above-described two embodiments for plating in their entirety, and can perform chemical degreasing. When the electrode is removed from the treatment tank 1, the electrode can be used as a treatment tank for chemical degreasing.

[0010]

According to the plating apparatus having the above-described structure, the cylindrical body standing in the processing tank from the center bottom surface of the processing tank.
And at least partially contact the inner surface of the cylindrical body.
And then interlocked with the drive unit provided outside the processing tank
With the rotating shaft protruding into the processing tank, only
From the insertion part of the rotating shaft where air may enter from the outside
Rotating shaft to prevent air from entering the processing tank
Can be projected into the processing tank, making it easy to
Can be vacuumed.

[0011] Then, with the rotation of the rotating container workpiece in a rotating vessel, bubbles existing in microangiopathy hole-bag hole, etc. of the workpiece to be processed while changing the position and posture, the negative pressure in the treatment tank Since the bubbles are separated and floated from the work, the bubbles can prevent the problem of the conventional processing apparatus in which the small holes and blind holes are not sufficiently degreased or plated.
