Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gasket sticking jig, and more particularly to a gasket sticking jig for fixing a gasket having an adhesive on one side and adhering it to a work.

[0002]

2. Description of the Related Art A conventional gasket sticking jig will be described.

In the pasting method using the gasket pasting jig of this conventional example, a step of pasting a gasket having a pressure sensitive adhesive applied to one side and a removable sheet stuck to the pressure sensitive adhesive side to a work The operator peels off the sheet little by little, and while peeling from the sheet, the adhesive part applied to one side of the gasket is pressed against the work while adjusting the shape of the gasket that can not be retained in the original shape.
I was sticking the gasket and the work.

Next, another example of the conventional gasket attaching jig will be described with reference to a known example.

As a conventional known example, Japanese Patent Laid-Open No. 4-3419
86 is known.

A gasket using a conventional gasket sticking jig and a method for manufacturing the gasket will be described with reference to the drawings.

FIG. 2 is a plan view of a seal portion of a hard disk drive using a conventional gasket.

The seal portion of the hard disk drive using the gasket of this conventional example is one annular core plate 11 and an annular seat portion 12 formed on both sides of the core plate 11 by a polymeric elastic material. It is composed of

Then, the sheet portion 12, which is a ring-shaped sealing member made of a polymeric elastic material, is brought into contact with both sides of the single ring-shaped new plate 11 and vulcanized and adhered to be integrally formed with the core plate 11.

As a result, the predetermined shape and size required for a gasket, for example, a gasket for a hard disk drive (HDD) can be maintained, the preparatory assembly and the assembling work can be facilitated, and the complete sealing performance and confidentiality can be maintained. ,Also,
It is possible to provide a gasket that does not generate gas and absorbs detergent, and a method for manufacturing the gasket.

[0011]

In the conventional pasting method described above, the gasket is peeled off from the sheet little by little, and the adhesive portion applied to the gasket is pressed against the work while adjusting the shape of the gasket to bond the gasket and the work. Therefore, there is a problem that working efficiency is poor and it is difficult to adhere the gasket to the work in its original shape.

Further, in the conventional pasting method described above, the assembly work is facilitated by using the gasket in which the annular sealing members made of the elastic polymer material are bonded to both sides of the annular core plate. However, in the other pasting methods, the core plate and the seal member made of a polymeric elastic material are integrally molded, and thus there is a problem that the cost becomes high.

[0013]

A gasket sticking jig of the present invention includes a base having an engraving of the same shape as the inner shape of the gasket, a plurality of gasket holders that move at right angles to both side surfaces of the base, and guides the gasket holder. It is characterized in that it is provided with a guide for carrying out, a spring for pressing the gasket retainer toward the center of the base, a block for supporting the spring and the gasket retainer, and a clamp for fixing the gasket retainer.

[0014]

Embodiments of the present invention will now be described with reference to the drawings.

FIG. 1 is a sectional view of an embodiment of a gasket sticking jig according to the present invention.

The gasket sticking jig of this embodiment comprises a base 3 having an engraving of the same shape as the inner shape of the gasket 1,
A plurality of gasket retainers 4 that move at right angles to both sides of the base 3, guides 6 installed at the bottom of the gasket retainer 4, and the gasket retainer 4 arranged on the side opposite to the base 3 and the gasket retainer 4 at the center of the base 3. A compression spring 7 that can be pressed in any direction, a block 8 that is arranged at one end of the compression spring 7 on the opposite side to the gasket retainer 4, and a block 8 that is arranged above the gasket retainer 4 and can be pressurized horizontally with the end face of the gasket retainer 4. Clamp 5 and the like.

Next, a method of attaching a gasket by the gasket attaching jig of this embodiment will be described with reference to the drawings.

An operator opens the gasket retainer 4 in the direction of both blocks 8 using the guide 6 as a guide, lowers the clamp 5, the gasket retainer 4 is sandwiched between the block 8 and the clamp 5, and the gasket retainer 4 is held by the friction force. To fix. The gasket 1 with the sheet 2 is set in the digging of the base 3 with the sheet 2 as the upper surface. The clamp 5 is pulled up to release the fixation of the gasket retainer 4, and the outer peripheral end surface of the gasket 1 set on the base 3 is pressed by the spring force of the compression spring 7 toward the center of the base 3 to fix the gasket 1. When fixed, the outer shape of the gasket 1 is elastically deformed. The sheet 2 is peeled off from the gasket 1. Even if the sheet 2 is peeled off, the inner diameter of the gasket 1 remains the original diameter due to the digging of the base 3.

An operator opens the gasket holder 4 in a direction toward both blocks 8 to a position where elastic deformation of the outer shape of the gasket 1 returns, and the clamp 5 is lowered to fix the gasket holder 4. After the sheet 2 is peeled off, the worker presses the work 9 from above onto the adhesive portion of the gasket 1 to bond the work 9 and the gasket 1, and removes the work 9 to which the gasket 1 is bonded from the base 3.

[0020]

As described above, according to the gasket attaching jig of the present invention, the gasket is set on the base having a dugout having the same shape as the inner shape of the gasket, and the outer shape of the gasket is elastically deformed through the gasket retainer. Press the spring force of the compression spring to peel off the sheet, then the operator opens the gasket retainer in both clamp directions and presses the work piece and gasket in the state where the gasket outer shape and the shape before elastic deformation are restored, and presses the work piece and gasket. By adhering, there is an effect that the gasket can be attached to the work in its original shape, and the gasket attaching step can be efficiently performed.
