Abstract

The present invention can conveniently control a coiling pitch distance and prevent a spring gasket and a processing tool from being deformed using an improved coiling method of coiling a planar material around a part of outer circumference of a bearing member rather than the conventional coiling method of coiling a planar material around a processing tool when a spring gasket is manufactured. According to the present invention, the method for manufacturing a spiral spring gasket is as follows: consecutively transferring a thin planar material and guiding the planar material using upper and lower clamps; discharging the planar material so that an end part of the planar material can be distorted on end parts of the upper and lower clamps; molding the planar material into an elastic spring gasket by bringing the transferred planar material into contact with a part of the outer circumferential surface of a bearing member arranged at an inclined angle with respect to the planar material being discharged; transferring the molded spring gasket; and continuously cutting the molded spring gasket using a cutter lifted by a cylinder when the length of the spring gasket meets a predetermined length.

The present invention prevents the deformation of the spring gasket and the machining tool by improving the coiling method in which the spiral spring gasket is rolled while being contacted with a part of the outer circumference of the bearing member, In addition, the coil pitch pitch can be easily adjusted.

Referring to FIG. 1, a method of manufacturing a spiral spring gasket according to the present invention is a method of manufacturing a spiral spring gasket according to the present invention, in which a sheet material having a thin thickness is continuously conveyed and a sheet material is guided by using upper and lower clamps (S1) (S2). After the plate member is brought into contact with a part of the outer peripheral surface of the bearing member disposed at an inclined angle with respect to the discharged plate member, a spring gasket (S3), and successively cutting (S4) using a cutting blade which is lifted and lowered by a cylinder when the length of the formed spring gasket reaches a predetermined length .

More specifically, in the process of coiling the plate member of the thin plate with the spring gasket, the end of the plate member is discharged at a twisted angle from the upper and lower clamps and the spring gasket wound at a predetermined pitch interval And coiled.

At this time, the pitch interval of the spring gasket can be varied by moving the bearing member forward and backward in the horizontal direction, and adjusting the interval between the upper and lower clamps and the bearing member.

That is, the pitch of the spring gasket has a linear relationship in which pitch intervals become wider as the end portions of the bearing member and the upper and lower clamps become wider, and pitch intervals become narrower as the intervals become narrower.

The spring gasket manufactured as described above is formed to have an elastic force in the form of being wound in one direction so as to have the same interval pitch, and can be mainly used for semiconductor equipment.

2 to 8, an apparatus for manufacturing a spiral spring gasket to which such a manufacturing method is applied is provided with a plate member 10a, which is disposed on the front surface of the main body 50 and has a thin thickness, A guide means 200 for guiding the plate member 10a to be conveyed by the conveying means 100 and a guide means 200 for guiding the plate member 10a to be conveyed by the guide means 200, A molding means 300 for contacting the plate member 10a with the spring member 10 to form a spring gasket 10 having an elastic force by spirally winding the plate member 10a with a predetermined pitch, And cutting means 400 which is lifted and lowered by a cylinder.

Referring to FIG. 2, the conveying means 100 includes upper and lower conveying rollers 110 and 120 which are rotationally driven by a driving force of a motor (not shown) and arranged up and down.

The forming means 300 may further comprise adjustment means 500 for adjusting the interval between the upper and lower clamps 210 and 220 and the bearing member 320 to adjust the pitch interval of the spring gasket 10 desirable.

The adjustment means 500 includes a support block 502 for rotatably supporting the bearing member 320 and a connection block 504 connected to one side of the support block 502 via a rod 505 in a lateral direction A lower unit 510 for supporting the lower portion of the connection block 504 and lifting and lowering the connection block 504 upward and downward and a lower unit 510 disposed above the connection block 504 and via a link member 530 And an upper unit 520 for transmitting a linear movement force to the connection block 504.

More specifically, the lower unit 510 includes a first elevating member 511 whose one end is connected to support the lower portion of the connecting block 504 and which is vertically movable up and down, A first adjusting bolt 512 for elevating and lowering the first elevating member 511 when the first elevating member 511 is rotated in the forward and reverse directions and a moving guide 513 And a first lift block 514 provided with a first lift block 514.

The upper unit 520 includes a second elevating member 521 disposed on the upper side of the connecting block 504 and capable of ascending and descending in the upward and downward directions and a second elevating member 521 fastened to the other end of the second elevating member 521, A second lift bolt 522 for raising and lowering the second lift member 521 and an elevation guide 523 for guiding the lift operation of the second lift member 521 on both sides, (524).

The link member 530 is composed of a plurality of links and one end of the link is connected to the second lift member 521 and the other end of the link is connected to the connection block 504 via the connection bracket 535 So that the connecting block 504 is moved forward and backward by the lifting force of the second lifting member 521.

The cutting means 400 has a cutting blade that can be raised and lowered by a known cylinder, and the spring gasket 10 formed by the cutting blade that is vertically lowered is cut at regular intervals.

It is preferable that the adjusting means 500 further comprise a fine adjusting means 600 for finely adjusting the ascending and descending operations of the second elevating member 521. The fine adjusting means 600 includes a fine adjustment means 600, And a slit hole 612 formed in the slit hole 612 of the rotating bar 610. The slit hole 612 is slidably engaged with the slit hole 612 of the rotating bar 610, A movable bar 620 movable along the inner circumferential surface of the slit hole 612 while supporting the lower portion of the moving bar 620 and moving the rotating bar 610 in a lateral direction of the moving bar 620, And a pedestal 630 having an inclined surface 631 for rotating.

The moving bar 620 has an assembling structure in which one end is assembled in a standing state with respect to the rotating bar 610 so as to pass through the slit hole 612 and the other end is held in contact with the slanted surface 631.

As a result, the fine adjustment means slides on the inclined surface 631 of the upwardly inclined base 630 as the moving bar 620 moves, and the rotating bar 610 is rotated around the axis .

For example, when the rotary bar 610 is rotated in a direction opposite to the clockwise direction about the axis, one end presses the second elevation member 521 downward to finely adjust the height of the second elevation member 521, The height of the member 320 can be finely adjusted.

3 and 4, the sheet material 10a is continuously fed to the conveying means 100 side through the separately wound rolls, and is introduced into the space between the upper and lower clamps 210 and 220 and transported.

For this purpose, the upper and lower clamps 210 and 220 are formed with grooves, respectively, so that the plate members 10a can be conveyed on the surfaces facing each other.

The upper and lower conveying rollers 110 and 120 are rotatably driven by the driving force of the motor and have a function of contacting the plate member 10a on both the upper and lower sides to move the plate member 10a in a linear direction .

5, the forming means 300 includes a discharge hole 310 for discharging the plate material 10a formed at the ends of the upper and lower clamps 210 and 220 and a discharge hole 310 for discharging the plate material 10a discharged through the discharge hole 310 And a bearing member 320 rotatable to wind the plate member 10a in contact with an end of the plate member 10a.

Preferably, the discharge hole 310 is formed to be inclined at an oblique angle toward the end so that the discharge hole 310 is twisted and discharged when the horizontally transferred plate material 10a is discharged.

This is because the sheet material 10a is discharged at an oblique angle before being contacted with the bearing member 320 after the sheet material 10a is conveyed along the inside of the upper and lower clamps 210 and 220, So that it can be improved.

6, the lower unit 510 is connected to the connecting block 504 via the supporting bracket 506 at the end of the first elevating member 511, so that the lower end of the first adjusting bolt 512 The first elevating member 511 is guided by the movement guide 513 and linearly moved upward and downward in the forward and reverse directions and the upward force is transmitted to the connecting block 504 through the supporting bracket 506 So that the height of the connection block 504 can be adjusted.

This allows the lower unit 510 to adjust the height of the support block 502 and the bearing member 320 connected to the connection block 504 and the rod 505.

7, the upper unit 520 is guided by the elevation guide 523 when the second elevation member 521 is rotated in the forward and reverse directions of the second adjustment bolt 522 The lifting force of the second lifting member 521 is transmitted to the first link 531 provided at one end so as to be connected to the second lifting member 521 to rotate the first link 531, The rotational force of the first link rotates the second link 532 provided at the other end via the other links.

Then, the second link 532 transfers the rotational force transmitted through the other links to the connection bracket 535 to move the connection block 504 connected to the connection bracket 535 back and forth in the horizontal direction.

The gap between the support block 502 and the bearing member 320 can be adjusted by moving the support block 502 and the bearing member 320 connected to each other via the rod 505 in the forward and backward movement of the connection block 504 Therefore, it can be seen that the pitch interval of the spring gasket can be adjusted as described above.

That is, the interval between the upper and lower parts of the bearing member 320 and the discharge holes 310 of the upper and lower clamps 210 and 220 can be adjusted through the upper and lower units 520 and 510.

8, the plate member 10a is conveyed while being supported by the upper and lower clamps 210 and 220 and discharged at an oblique angle through the discharge hole 310, And is wound in one direction while being in contact with a part of the periphery.

At this time, the plate member 10a is made of a spring gasket 10 having an elastic force and a flexible characteristic while the pitch between the wound nodes is wound at a constant interval.

Thereafter, as described above, it is cut to a predetermined length through the cutting means 400, so that the user can easily manufacture the spiral spring gasket 10 of the desired specification.

Therefore, in the process of manufacturing the spring gasket 10 mainly applied to the semiconductor equipment, the present invention is not a method of winding the existing plate material 10a on the machining tool so as to be coiled, but is in contact with a part of the outer circumference of the bearing member 320, By improving the coiling method, it has a useful effect of preventing deformation of the spring gasket 10 and the machining tool by minimizing the frictional resistance generated during the coiling process.

The gap between the discharge hole 310 and the bearing member 320 of the upper and lower clamps 210 and 220 can be easily adjusted using the adjusting means 500 and the upper and lower sides of the bearing member 320 It is advantageous in that it is possible to easily adjust the pitch interval between the nodes rolled during the coiling process
