Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a cleaning device, and particularly to a cleaning device for cleaning the front and back surfaces and inner and outer circumferences of a magnetic storage medium disk (hereinafter referred to as a disk).

[Prior Art] In the conventional cleaning method, an operator manually selects one disk from a group of disks arranged at equal intervals in a magazine and immersed in pure water.
After taking out the disk, soak a soft, water-absorbing sponge in cleaning liquid to wipe off dust that has adhered to the front and back surfaces and inner and outer circumferences of the disk during the previous process and transportation. Next, soak the sponge in pure water,
After wiping off the cleaning solution adhering to the disk,
Rinse by soaking in a pure water tank. Furthermore, a method has been adopted in which the disk is dried in a fluorocarbon dryer and the disk after cleaning is stored in a magazine.

Another method using jigs and tools is to attach a disk to a spindle connected to a motor, and while rotating the disk, the worker soaks a sponge alternately in cleaning liquid and pure water to wipe away dust. It had been taken.

[Problem that the invention attempts to solve]

In the conventional cleaning method described above, it is necessary for the worker to manually clean the disk, wash it with water, and handle it, and also manually clean the surface, back, outer periphery, etc. of the disk with a sponge.
The disadvantage was that the work efficiency was extremely low because the inner circumference was wiped sequentially.

[Means for solving the problem] The cleaning device of the present invention has one unit above the vertical plane,
a chuck mechanism composed of three rotating rollers, two of which are arranged on the same diameter at the lower side, each having a concave groove on the outer periphery, and a rotational drive source connected to the lower rotating roller;
An inner cleaning mechanism includes a brush shaft arranged perpendicularly between the three rotating rollers and has brushes arranged in the radial direction, and a linear drive source connected to the brush shaft; It has an axis between two rotating rollers, two sets of brush shafts in which brushes are arranged facing vertically facing each other, a rotary drive source connected to each brush shaft, and a linear drive source. a brush shaft having an axis perpendicular to the vertical plane above the lower rotating roller and having brushes arranged in the radial direction; a rotary drive source connected to the brush shaft; and a linear drive source. an outer periphery cleaning mechanism configured with the above-mentioned rotating roller;
The discharge nozzle includes:

〔Example〕

Next, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a perspective view showing an embodiment of the present invention, and FIG. 2 is a central sectional view showing the operating state of the cleaning device shown in FIG.

The chuck mechanism 10 has a concave groove on the outer periphery to hold and rotate the disk 11, and includes a rotary roller 13 arranged above a vertical plane and connected to a linear drive source 12 for vertical movement, and a rotary roller 13 connected to a linear drive source 12 for vertical movement. It consists of a rotating roller 16 and a rotating roller 17 arranged below the surface and connected to a rotational drive source 15.

The inner periphery cleaning mechanism 20 includes each of the rotating rollers 13 and 1.
A brush shaft 22 is arranged at right angles to the right in the middle of 6 and 17 and has a plurality of brushes 21 in the radial direction.
and a linear drive source 23 connected to the brush shaft 22.

The surface cleaning mechanism 26 includes the rotating rollers 16 and 17.
brush shafts 29 and 30 each having brushes 27 and 28 facing toward the disc 11 with the disc 11 sandwiched between them;
Rotary drive sources 31 and 32 connected to the brush shafts 9 and 30, respectively,
9 and 30, and linear drive sources 33 and 34 connected to each other.

The outer periphery cleaning mechanism 37 is arranged above the rotary roller 16 at right angles to the disk 11, and is composed of a brush shaft 39 provided with a plurality of brushes 38 in the radial direction, and a linear drive source 40 connected to the brush shaft 39. be.

The discharge nozzles 43 and 44 are arranged above the recording disk 11 so as to face each other and face the disk 11, and in order to alternately discharge cleaning liquid and pure water (not shown), a cleaning liquid tank and a pure water tank are arranged. (not shown).

Next, the operation of the cleaning device shown in FIG. 1 will be explained.

In the chuck mechanism 10, with the rotating roller 13 raised by the drive of the linear drive source 12, the disk 11 is moved to each rotating roller 13, 16, 17.
When the disc 11 is mounted between the discs 11 and 11, the rotary roller 13 is lowered by the drive of the linear drive source 12, and the disc 11 is held. Next, when rotational motion is transmitted to the rotating roller 16 by the rotational drive of the rotational drive source 15, the disk 11 starts rotating. Furthermore, when the cleaning liquid starts to be jetted from the discharge nozzles 43 and 44,
The inner circumference cleaning mechanism 20 is activated, and the brush 21 is driven by the linear drive source 23 to reciprocate within the disk 11 to clean the inner circumference of the disk 11. Further, the surface cleaning mechanism 26 is activated, and the brushes 27 and 28 are driven by the rotary drive sources 31 and 32 and the linear drive sources 33 and 34, respectively, to scrub and clean the front and back surfaces of the disk 11. Further, the outer periphery cleaning mechanism 37 is activated, and the brush 38 is driven by the linear drive source 40 to reciprocate around the outer periphery of the disk 11 and clean the outer periphery of the disk 11, thereby cleaning the entire surface of the disk 11. The work is finished. Furthermore, in this state, by switching the liquid ejected from both the discharge nozzles 43 and 44 from the cleaning liquid to pure water, the water washing operation is continued as it is. When the water washing operation is completed, each washing mechanism returns to its original state, the discharge nozzles 43 and 44 stop spouting pure water, and the disk 11 continues to rotate and is spin-dried. When the spin drying is completed, the rotating roller 13 returns upward, thereby completing the entire operation in which the disk 11 has been washed, rinsed with water, and dried. FIG. 2 shows the disk 11 and brushes 21, 27, of the embodiment shown in FIG.
28 and 38 are shown.

[Effects of the invention] The cleaning device of this invention is equipped with dedicated brushes for each cleaning part of the disk, so it can perform cleaning and rinsing work reliably, and it can obtain products with stable quality and high precision. In addition, since each cleaning mechanism is consolidated and works at the same time, work efficiency is high.
This has the effect of allowing products to be produced at low cost.
