Abstract

(57) [Summary] [Purpose] To eliminate dust by preventing contact between the inner diameter of the magnetic disk and the outer diameter of the spindle. [Structure] The magnetic disk 7 is suctioned and fixed to the suction pad 9 by air suction from the suction hole 6, and the spindle 8
An insertion is made into the The position of the magnetic disk 7 is corrected by the horizontal movement 14 of the magnetic disk 7 by the floating portion 2, and insertion into the spindle 8 becomes possible. Furthermore, when the magnetic disk 7 is inserted, compressed air is supplied from the compressed air outlet 5. Send it inside the suction pad 9.
The compressed air sent into the spindle 8 and the magnetic disk 7
As a result, a film of compressed air is generated in the gap between the outer diameter of the spindle 8 and the inner diameter of the magnetic disk 7. This compressed air film can prevent the inner diameter of the magnetic disk 7 and the outer diameter of the spindle 8 from coming into contact with each other due to the horizontal movement 14 of the magnetic disk 7.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to a magnetic disk assembly hand mechanism, and in particular to a magnetic disk assembly hand mechanism for a spindle. This invention relates to an assembly hand mechanism for inserting a lock.

0002

[Conventional technology]

Conventionally, this type of magnetic disk assembly hand mechanism has been used to attach the magnetic disk to the spindle. To prevent galling between the outer diameter of the spindle and the inner diameter of the magnetic disk during insertion, A matching mechanism was adopted. This floating mechanism allows the magnetic disk to horizontal movement is possible and the outer diameter of the spindle and the inner diameter of the magnetic disk come into contact. The magnetic disk moves horizontally due to the reaction force generated, preventing galling. It had become a beautiful organization.

0003

[Problem that the idea aims to solve]

In this conventional magnetic disk assembly hand mechanism, the spindle outer diameter and magnetic A magnetic disk device that has become a complete product because it cannot avoid contact with the inner diameter of the disk. It is said that it is not possible to prevent the generation of dust, which is one of the factors that affect the quality of There is a problem.

0004

[Means to solve the problem]

The magnetic disk assembly hand mechanism of the present invention attracts and holds magnetic disks. A holding means and the magnetic disk held by the holding means are inserted into the spindle. a positioning means for positioning the magnetic disk when the magnetic disk is inserted into the spindle; Compression for blowing compressed air from the inner diameter of the magnetic disk to the outer diameter of the spindle and air blowing means.

[0005]

【Example】

Next, the present invention will be explained with reference to the drawings.

[0006] FIG. 1 shows an embodiment of the present invention, (a) is a sectional view of this embodiment, and (b) is a sectional view of this embodiment. It is a bottom view of the suction pad in an example.

[0007] In FIG. 1, this embodiment uses air suction from the suction hole 6 through the suction pipe 4. a suction pad 9 that attracts and holds the magnetic disk 7; Floating section 2 that horizontally moves the magnetic disk 7 to insert it into the spindle 8 and the centering of the suction pad 9 with respect to the insertion of the magnetic disk 7 into the spindle 8. Cylinder 1 that performs the recording, and the magnetic disk when the magnetic disk 7 is inserted into the spindle 8. Compressed air is sent from the inner diameter of the spindle 7 to the outer diameter of the spindle 8 through the compressed air outlet 5. It has a compressed air blow pipe 3 that blows air.

[0008] FIG. 2 shows the state in which the magnetic disk is inserted into the spindle in this embodiment, and (a ) is a cross-sectional view showing the inserted state of the magnetic disk, and (b) is the initial state when the magnetic disk is inserted. (c) is a diagram showing the state after the magnetic disk is inserted.

[0009] Next, the operation of this embodiment will be explained with reference to FIGS. 1 and 2.

0010 The magnetic disk 7 is suctioned and fixed to the suction pad 9 by air suction from the suction hole 6. Insertion into the spindle 8 is performed in this state. At this time, as shown in Figure 2 (b) , until the spindle side bevel 11 and the magnetic disk side bevel 12 overlap, The amount of deviation between the spindle center position and the magnetic disk inner diameter center position is up to 13. Due to the horizontal movement 14 of the magnetic disk 7 by the floating part 2, (c ), the position of the magnetic disk 7 is corrected and the magnetic disk 7 is moved to the spindle 8. can be inserted.

[0011] Furthermore, when the magnetic disk 7 is inserted, compressed air is supplied to the suction pad from the compressed air outlet 5. into the inside of the pad 9. The compressed air sent in is connected to the outer diameter of the spindle 8 and the magnetic disk. The exhaust air will be emitted only from the gap between the inner diameter of the disk 7, and the air will be exhausted due to this evacuation. A film of compressed air is generated in the gap between the outer diameter of the spindle 8 and the inner diameter of the magnetic disk 7.

0012 This film of compressed air allows the magnetic disk 7 to move horizontally 14. Contact between the inner diameter of the disk 7 and the outer diameter of the spindle 8 can be prevented.

[0013]

[Effect of the idea]

As explained above, the present invention includes a holding means that attracts and holds a magnetic disk; The magnetic disk held by this holding means is positioned to be inserted into the spindle. positioning means and the inner diameter of the magnetic disk when inserting the magnetic disk into the spindle. and compressed air blowing means for blowing compressed air from the spindle to the outer diameter of the spindle. This causes a film of compressed air to form in the gap between the outer diameter of the spindle and the inner diameter of the magnetic disk. Therefore, there is no contact between the outer diameter of the spindle and the inner diameter of the magnetic disk. This has the effect that it can be inserted without causing a strike.
