Description

DETAILED DESCRIPTION OF THE INVENTION U) Technical Field of the Invention The present invention provides a method for quickly cleaning and drying a magnetic disk material disk or a disk coated with Korg ink 1 on the material disk in the same apparatus without requiring any manpower. The present invention relates to a disk cleaning and drying device that ensures reliable cleaning and drying.

(2) Conventional technology and problems Conventionally, in order to clean and dry a disc, the disc was set on a bench with running water, and a person scrubbed the disc surface with their hands using a sponge, etc., and then dried the disc separately. The central hole of the disk is hooked onto the rotating shaft using a machine, and the disk is rotated at a low speed of 400 to 500 PM while applying a volatile solvent such as alcohol to the surface of the disk. The water on the surface of the disk is replaced with a volatile solvent by coating the disk, and the evaporation of this volatile bath agent is used to perform displacement drying. However, in this case, a person manually rubs the disk surface with a sponge or the like to clean it, making it impossible to uniformly clean the disk surface.

In addition, the washed towelette had to be placed in a separate dryer, which required a lot of man-hours. Furthermore, in the conventional dryer mentioned above, the rotation speed of the disc is low, so the centrifugal force does not sufficiently shake off the water on the disc surface, and even if a volatile solvent is applied, it cannot completely replace the water. Therefore, when the volatile bath agent evaporates and dries while there is water partially remaining on the disk surface, cloudiness or spots may occur at the disk interface. Once such cloudiness and spots occur, they cannot be removed, and even if coating is applied afterwards, problems such as the coating film coming off may occur, which may affect the quality and reliability of the magnetic disk. The result was a decrease in Also,
The use of volatile solvents may have some adverse effects on the human body of workers.

(3) Purpose of the Invention The present invention has been made in response to the above-mentioned circumstances, and it is possible to uniformly clean the disk surface without requiring human labor, and the disk after cleaning can be used as it is in the same device. The quality of magnetic disks is improved by drying without the use of volatile solvents,

Then rinse again with warm water.

A cleaning brush 7 is provided near the spindle 5. The cleaning brush 7 is composed of two flat donut-shaped sponge brushes, and has a donut-shaped central hole hooked to the tip of a cleaning brush hinge 9 that is rotated by an appropriate power source such as a motor B. , and these two pictures are arrows A and I
They can move toward or away from each other as shown in 3, and can move toward or away from the disk 3 as shown by arrows C and D together with the cleaning brush spindle 9. When cleaning the disk 3, the cleaning brush T moves in the direction of the arrow C and clamps a portion of the disk 3 from both sides thereof, thereby cleaning the surface of the disk 3 uniformly.

An exhaust fan 10 is provided on one side wall of the container 1. This exhaust fan 10 is rotated by a motor or the like, and discharges the humid air inside the container 1 to the outside through the air tact 11 when the disk 3 is washed and then dried. be. An air supply fan 12 is provided on the other side wall of the container 1 . The air supply fan 12 is rotated by a motor or the like, and supplies ambient temperature air from the outside into the container 1 when drying the disk 3. Here, if the container 1 is installed in a clean room with a cleanliness level of about class 100, clean air at room temperature can be supplied into the nuclear container 1 from the air supply fan 12.

A drip-proof ceiling plate 13 is provided on the top plate portion of the container 1. This drip-proof type ceiling plate 13 has a cleaning ridge disk 3.
This is to prevent water droplets from falling from the top plate of the container 1 when drying.The top plate has a two-layer structure, the lower plate is a perforated plate, and the upper plate is equipped with a suction fan 14. Water droplets on the top plate, etc., are sucked by the negative pressure of 14 and discharged to the outside.

For example, on the rear surface portion 15 of the container 1, there is provided a control device for controlling the operation of the spindle 5, Java link portion 6, cleaning brush 1, cleaning flange spindle 9, exhaust fan 10, air supply fan 12, suction fan 14, etc. It has a built-in control device that controls the washing and drying processes. This control device allows the washing and drying steps to be carried out quickly and reliably within the same container 1.

That is, first, the front door 2 is opened and the disk 3 to be cleaned is attached to the fifth tip of the spindle, and then the front door 2 is closed and hermetically sealed. Next, about 60℃ from the Java link part 6
Pre-wash 30 disks 1111 surfaces by squirting hot water. Next, the two cleaning brushes 7.7 move toward the disk 3 while being separated from each other (see arrow C), and stop when the disk 3 enters between them, and the two cleaning brushes 7.7 approach each other and sandwich a portion of the disk 3 from both sides thereof. Next, while applying warm water to the Java link part 6, the motor 4 is rotated to rotate the spindle 5 by 1q as shown by arrow E, and the disk 3 is rotated.
Rotate at a high speed of about 3000 Rk'M. At this time, the motor 8 is rotated and the cleaning brush spindle 9 is also rotated as indicated by the arrow 1.
The entire surface of the disk 3 is uniformly cleaned by the sandwiching between the two cleaning brushes I and 7 and the relative rotational movement of the disk 3 and the cleaning brushes 7 and 7. Next, after an appropriate period of time has passed, the spindle 5 and the cleaning brush spindle 90 rotations are stopped υ, the cleaning brush 7,
7 are separated from each other and released from the disc 3, and are retracted as shown by the arrow. Next, hot water of about 60° C. is once again jetted from the shower link portion 6 and sprayed onto both 1l and 11 surfaces of the disk 3 for rinsing. In this way, cleaning of the disk 3 is completed.

The disk 3 enters the drying process until it is attached to the tip of the spindle 5 in the container 1.

First, the exhaust fan 10 provided on one side wall of the container 1 is rotated to exhaust the air inside the container 1 to the outside via the exhaust duct 11, while the air supply fan 12 provided on the other side wall is rotated. Air at room temperature from outside is supplied into the container 1. In addition,
When the container 1 is installed in a clean room as described above, room temperature clean air can be supplied into the container 1 from the air supply fan 12. At the same time, the suction fan 14 of the drip-proof ceiling plate 13 is rotated to discharge all water droplets and moisture attached to the top plate, etc. inside the container 1 during cleaning to the outside. In this state, the motor 4 is rotated to rotate the disk 3 at a high speed of about 600 ORPM. At this time, the moisture on the surface of the disk 30 is removed from the water.

The centrifugal force generated by the high-speed rotation sufficiently separates and dehydrates the air.The humid air in the container 1 due to the separated and dehydrated moisture is exhausted to the outside by the exhaust fan 10, and the air at room temperature or clean air is supplied by the air supply fan 12. The disk 30 is supplied into the container 1 and heated to around 60°C by hot water during cleaning.
When the above air or clean air comes into contact with the surface,
Disk 3 is dried. In this way, disk 3
drying is completed.

(6) Effects of the Invention Since the present invention has been developed as described above, the tee 7' 3, which rotates at a barrel speed, can be sandwiched from both sides with the cleaning brush 7.7, thereby eliminating the need for manpower. The disk surface can be cleaned evenly. Further, since the cleaned disk 3 enters the drying process in the container 1 in its best state, the number of work steps can be reduced and cleaning and drying can be performed quickly. Furthermore, since the disk 3 is rotated at high speed even when drying, moisture adhering to its surface is sufficiently separated and dehydrated, and room temperature air can simply touch the surface of the disk 3 without using any volatile solvents. Can be dried. Therefore, scratches and spots do not occur on the surface of the disk 3 as in the conventional case, and the quality η and reliability of the magnetic disk can be improved. Furthermore, since no volatile solvents are used,
There is no adverse effect on the human body of the worker.
