Abstract

PURPOSE:To dispense with a forceps, to shorten working time, and to prevent a load spring and a magnetic disk from being damaged by regulating the deflection quantity of the load spring by attraction. CONSTITUTION:When the head insertion jig of a magnetic disk device is inserted between the load springs 9, 10 of a magnetic head, attraction heads 1, 2 are attracted with the load springs 9, 10, and also, the entire length of a bellows material 3 is reduced, and the deflection quantities of the load springs 9, 10 are regulated, then, the load springs 9, 10 can be inserted between the magnetic disks 7, 8. When a vacuum pump 6 is stopped and the head insertion jig is removed from between the load springs 9, 10, the magnetic head comes in contact with the magnetic disk, then, a prescribed loading state can be set. In such a way, it is possible to prevent much time for work to load and remove the jig from being consumed or the load spring and the magnetic disk from being damaged due to the use of the forceps.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is used when a magnetic head is applied with a pressing force by a leaf spring of a magnetic disk device and has a minute flying height, and is installed between two magnetic disks. The present invention relates to a head insertion jig for a magnetic disk device.

[Conventional technology]

Conventionally, in magnetic disk drives, when incorporating a magnetic head for writing and reading information on a magnetic disk, the magnetic head had to be inserted between two stacked magnetic disks, but at this time, the magnetic head had to be inserted between two stacked magnetic disks. Using the set, read/write element (R/W element)
A jig is attached to the load spring that supports it to regulate and fix its deflection, and after the insertion is complete, the jig is removed using a bin set and assembled so that the magnetic head can be loaded onto the magnetic disk. was being carried out.

[Problem to be solved by the invention]

In the conventional magnetic disk assembly method described above, a jig that regulates and fixes the deflection of the load spring that supports the magnetic head must be attached and removed using a bin set, and the load The disadvantage is that the fixing position of the spring is narrowly regulated, making the work difficult and therefore requiring a lot of time. Also,
If the operator is not skilled, the load spring or magnetic disk may be damaged, and the sliding between the jig and the load spring may generate dust.

[Means to solve the problem]

A magnetic head insertion jig for a magnetic disk device according to the present invention includes two suction heads having suction holes penetrating through a plate-like member;
a bellows member connecting the two suction heads at both ends;
It is configured to include the two suction heads, an exhaust pipe and a vacuum pump that create a vacuum inside the bellows material.

〔Example〕

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

FIG. 1 is a perspective view showing one embodiment of the present invention, and FIG. 2 is a perspective view showing one embodiment of the present invention.
FIG. 3 is a side view showing the operating state of the embodiment shown in the figure.

In FIG. 1, two suction heads 1.2 are connected by bellows 3. In FIG. When an object is brought into contact with the suction surface 4, the exhaust pipe 5 and vacuum pump 6 create a vacuum inside the suction heads 1, 2 and the bellows material 3, and the object is attracted to the suction head 1.2 and further absorbed by the bellows material 3. The overall length is shortened and the two suction heads 1 and 2 move closer to each other.

In Fig. 2, the head insertion jig of the magnetic disk device of this embodiment is inserted between the load springs 9.10 of the magnetic head, which is wider than the space between the plates of the magnetic disk 7.8 (Fig. 2(a)). , the suction heads 1.2 come into contact with the load springs 9, 10, and the suction heads 1, 2 are attracted to the load springs 9°10, and the total length of the bellows material 3 is shortened, and the amount of deflection of the load springs 9, 10 is reduced. The load spring 9.10 can be inserted between the plates of the magnetic disk 7.8 (FIG. 2(b)). With the load springs 9 and 10 inserted between the magnetic disks 7 and 8, the vacuum pump 6 is stopped, and the head insertion jig of the magnetic disk drive of this embodiment is inserted between the load springs 9 and 8.
When the magnetic head is removed from between 10 and 10, the magnetic head comes into contact with the magnetic disk and enters a predetermined loaded state (FIG. 2(C)).

〔Effect of the invention〕

The head insertion jig for a magnetic disk drive of the present invention regulates the amount of deflection of the load spring by adsorption, thereby eliminating the need for tweezers used when installing and removing the jig, making the work easier. Time is reduced. Further, since a set of bins is not required when regulating the amount of deflection of the load spring, damage to the load spring and the magnetic disk can be prevented. Furthermore, since the amount of deflection of the load spring is regulated by suction, sliding between the load spring and the jig is prevented, and the generation of dust is prevented.
