Description

The present invention relates to a method for manufacturing a cut plate having a notch penetrating in the plate thickness direction and a cut plate.

The structure of the cushioning material is such that the height of the volume space and the complicated shape are provided in the volume space, and the height in the volume space and the complicated shape are used, and the cushioning material absorbs the external impact received by the package. , Has the function of protecting the package.

Along with this, the preparation and burden of equipment related to production, ingenuity to secure the height, and the volume of material required may depend on the shape and purpose, but we will proceed with development based on that. I had in mind that it was indispensable, so there was no particular problem.

However, in order to manufacture a cushioning material having a complicated shape, there is an increase in burden such as preparation of equipment and development and preparation of equipment.

Cushioning materials with complicated shapes have a large number of manufacturing processes, and if the number of manufacturing processes is large, material loss tends to increase. There was a tendency for many points to be considered.

In addition, regarding the production of members that exert a sufficient effect on the thickness of the space of the cushioning material, if a member that merely satisfies the height of the space is produced, the overall development period and the burden on complicated production will increase. There was a problem such as an increase in verification time for the effect of height space generation.

For example, since the thickness of the space of the cushioning material is required, the required volume ratio is inevitably high with respect to the volume of the material used. On the other hand, if the volume of the material used is reduced, the volume is also reduced or the structure becomes complicated. Since the above relationship may be established, it is difficult to reduce the amount of materials used.

As a method for improving such a problem, a method of manufacturing a raised portion by using several fiber materials such as a non-woven fabric in order to secure a space is known (see, for example, Patent Document 1).

In addition, straight cuts that are regularly arranged on the surface of the paper are made so as to penetrate from one side to the other, and by pulling in a certain direction, the flat surface is changed into a net shape. It is known that a height space is generated by overlapping the above (see, for example, Patent Document 2).

[First Embodiment]
The first embodiment of the notch plate according to the present invention will be described with reference to FIGS. 1 and 2. Here, FIG. 1 is a perspective view showing the notch plate 20a of the first embodiment. FIG. 2 is an overall plan view of the notch plate 20a shown in FIG. 5 to 9 are examples of manufacturing the notch plate 20a of the present embodiment. Further, FIGS. 10 and 11 are examples of other production of the notch plate 20a of the present embodiment.

Here, the notch plate 20a shown in FIGS. 1 and 2 is an example manufactured as a cushioning material. Further, FIGS. 5 to 9 are examples (prototypes) in which a silicon sheet is used as the material of the cutting plate 20a. Further, FIGS. 10 and 11 are examples (prototypes) of using paper as the material of the notch plate 20a.

In the flat cut plate 20a, as shown in FIG. 2, the cut plate 20a is formed into columns 17 along the direction perpendicular to the predetermined pulling direction A01 and pulling direction B02 on the plate surface. 20a is divided into a plurality of columns 17 and divided.

The notch plate 20a is provided with a notch penetrating in the plate thickness direction. The cut plate 20a is provided with cuts in the plate having a predetermined cut pattern shape and arrangement for each column 17 along the vertical direction on the plate surface with respect to the predetermined pulling directions A01 and B02 of the plate as the material. Be done.

When the plate-shaped cut plate 20a is pulled in the predetermined pulling directions A01 and B02, a raised protrusion is formed on the plate surface.

The direction perpendicular to the predetermined pulling direction A01 and the pulling direction B02 of the cut plate 20a in FIG. 2 is the Y direction, and the parallel direction is the X direction. Hereinafter, the structure of the notch plate 20a will be described with reference to FIGS. 1 and 2.

The column 17 is provided with cuts having a predetermined pattern shape and arrangement (also referred to as a cut pattern shape and arrangement) along the vertical directions of the pulling directions A01 and B02. The cuts provided for each of the columns 17 will be described with reference to the following parameters and the like that serve as a reference for determining the pattern shape and arrangement.

In the column 17 shown in FIG. 2, the cut pattern unit is repeated with respect to the predetermined pattern shape by inverting the center line of the column 17 as a boundary and changing the arrangement (also referred to as pattern arrangement) in the column 17. .. In the column 17, the pattern shape and the pattern arrangement are determined, for example, at the following intervals.

The first interval 11 is an interval between the notches that are adjacent in the horizontal direction between the adjacent columns 17.

The second interval 12 is an interval between the cuts facing each other in the lateral direction in the own column 17.

The third interval 13 is an interval that determines the degree of ridge in the ridge portion of the notch.

The fourth interval 18 is an interval of cuts that rise in the same direction in the vertical direction in the own column 17.

The angle 14 is an angle with respect to the parallel direction of the column 17 and the notch to be the target of the third interval 13, and is an angle in the range of 0 degrees to 90 degrees.

The fifth interval 19 is an interval between the vertices on the open side of the V-shape of the V-shaped cut 06, which is provided in the notch of a predetermined pattern.

The sixth interval 21 is the leftmost side of the lowermost end of the notch arranged on the left side in the column 17, and the rightmost rightmost end of the notch arranged on the right side in the column 17 adjacent to the left side of the own column 17. The intervals are parallel to the X direction.

The seventh interval 22 is the length of the cut in the line to be the target of the third interval 13.

The eighth interval 23 is the point centered on the rightmost end of the notch arranged on the left side of the column 17 with respect to the Y direction, and the most of the notch arranged on the right side of the column 17 adjacent to the left of the own column 17. It is the distance from the center point with respect to the Y direction at the left end.

The right apex 15 is the leftmost tip of the notch to be arranged in the vertical direction of the pulling directions A01 (left) and B02 (right) shown in FIG. 2 and to the right of the notch facing each other. The left apex 16 is the rightmost tip of the notch arranged in the vertical direction of the pulling directions A01 and B02 shown in FIG. 2 and on the left side of the notch facing each other. The distance between the right apex 15 and the left apex 16 is defined as the cut X interval.

The flat cut plate 20a is cut in a predetermined pattern shape and arrangement so as to penetrate the plate thickness from one surface to the other surface in the plate thickness direction in each column 17. By pulling the flat notch plate 20a in which the notch is made in the direction perpendicular to the column 17 on the surface (pulling direction A01 and pulling direction B02), one surface side as shown in FIG. 1 The unevenness 03 and the unevenness 04 on the other surface side are generated.

Here, the unevenness 03 on one surface side and the unevenness 04 on the other surface side shown in FIG. 1 are opposite cuts in the cut pattern in the cut plate 20a, and the unevenness 03 on one side is the separation of the cuts. The unevenness 04 on the other side is a portion that rises to one surface on the side where the cut is separated. Hereinafter, the unevenness 03 on one surface side will be mainly described and described, but the same applies to the unevenness 04 on the other surface side.

As a result, both sides of the cut plate 20a become uneven, and a space having a height equal to or larger than the volume of the flat cut plate 20a can be generated. The cut pattern shape and arrangement shown in FIGS. 2 and 4 is one of the examples, and does not limit the cut pattern shape and arrangement of the present invention.

When the first interval 11 is widened as a method of arranging the cuts, the height of the unevenness 03 on one surface side generated on the surface after the cuts are made and pulled in the X direction becomes high. In addition, the area ratio of the flat thin plate that can be seen from the surface increases.

When the second interval 12 is widened, after making a notch and pulling in the X direction, the area ratio of the holes becomes low so that it can be seen from the surface, and the interval of the unevenness 03 on one surface side generated on the surface widens in the pulling direction. , Shrink in the Y direction.

When the third interval 13 is widened, after making a notch and pulling in the X direction, the unevenness 03 on one surface side generated on the surface tends to rise, and the hole becomes elongated with respect to the pulling directions A01 and B02. Since the extension rate in the X direction increases, it is reduced as a whole with respect to the Y direction. The third interval 13 is an interval that affects the size of the holes.

When the fourth interval 18 and the fifth interval 19 become dense, the interval of the unevenness 03 on one surface side after making a notch and pulling in the X direction becomes dense in the Y direction.

When the first interval 11 is smaller than the second interval 12, the effect of raising the midpoint 05 is reduced regardless of the angle of the angle 14.

When the second interval 12 becomes wider and the third interval 13 becomes shorter, the extension rate when pulled in the X direction decreases, and the ridge heights of the unevenness 03 on one surface side and the unevenness 04 on the other surface side also decrease. Decrease.

Both parallel cuts in the second interval 12 are continuous divisions of the width 24 in the column 17, alternating in the Y direction with respect to the cuts in the column 17, or regularly reversed at the same angle 14. In the range where the angle 14 is tilted in the direction and the angle is less than 0 to 90 degrees, after pulling, the whole is reduced in the Y direction, and the distance between the unevenness 03 on one surface side in the Y direction becomes dense. As the angle 14 approaches 90 degrees, the reduction ratio decreases in the Y direction. When the angle 14 is 90 degrees, the reduction ratio is 0 (zero) with respect to the Y direction.

Regarding the size of the holes, since the 5th interval 19 and the 7th interval 22 affect, if the 5th interval 19 or the 7th interval 22 is lengthened, the hole becomes large, and if the 5th interval 19 or the 7th interval 22 is shortened, the hole becomes large. , The hole becomes smaller.

Regarding the uplift height of the unevenness 03 on one surface side and the unevenness 04 on the other surface side, since it affects the eighth interval 23, if the uplift height is required, it is necessary to widen the eighth interval 23. is there.

When the first interval 11 and the second interval 12 are narrowed, the ridge densities of the unevenness 03 on one surface side and the unevenness 04 on the other surface side of the cut plate 20a in the X direction become dense.

When the third interval 13, the fourth interval 18, and the fifth interval 19 are narrowed, the ridge density in the Y direction of the unevenness 03 on one surface side and the unevenness 04 on the other surface side becomes dense.

Regarding the midpoint 05, both the sixth interval 21 and the notch X interval approach 0 (zero), and at the same time, when the angle 14 is 45 degrees or more, the effect of raising the midpoint 05 decreases. .. When the sixth interval 21 becomes 0 (zero) or less, the intermediate point 05 hardly rises. (The range where you can hardly get up means that the rising angle is 0 (zero) degrees to 10 degrees)

When a notch is made in the flat notch plate 20a with a predetermined pattern shape and arrangement so as to penetrate the plate thickness from one surface to the other surface in the plate thickness direction as shown by the line shown in FIG. Or, in the case where the cut plate surface is divided into predetermined plane units and a movable portion is provided on the dividing line, with a configuration in which one surface is separated from the other surface in the plate thickness direction by the line shown in FIG. A hole is generated after the cut plate 20a is manufactured and pulled in the pulling directions A01 and B02.

Further, when the cutting plate 20a is made of a material having a restoring force, or when the cutting plate 20a is contracted in the direction opposite to the pulling directions A01 and B02, the generated holes can be returned to the state before the holes were generated. Is.

FIG. 1 is a perspective view showing a state in which the unevenness 03 on one surface side and the unevenness 04 on the other surface side of the notch plate 20a of the first embodiment are raised. That is, in FIG. 1, a notch is made to penetrate in the plate thickness direction along the line shown in FIG. 2, and the notch plate 20a (for example, a plate in which a notch is made by using a silicon sheet) is pulled in the pulling direction A01 and the pulling direction. It is in a state of being stretched to B02.

As a specific example, the cut plate 20a is used as a cushioning material by using, for example, a silicon sheet as shown in the examples of the prototypes of FIGS. 5 to 9 as the material of the cut plate 20a of the present embodiment shown in FIG. Fix it to the tray and place the electronic components on the silicon sheet. Further, by sandwiching the electronic component from above and below with a silicon sheet obtained by extending the notch plate 20a from above, the electronic component can be covered with a cushioning material and transported in a stable holding state.

Further, in the notch plate 20a using the silicon sheet as a material, each protrusion portion of the unevenness 03 on one surface side is individually deformed along the shape of the electronic component, and the electronic component is fixed by the restoring force of each protrusion portion. Has the effect of

In the conventional technique, for example, when the cushioning material is a sponge, if there is a protruding part in the shape of the package, the pressure exerted by the cushioning material on the package tends to increase in quasi-proportional to the height of the protrusion. ..

On the other hand, according to the notch plate 20a of the present embodiment, for example, when a silicon sheet is used for the notch plate 20a, the unevenness 03 portion on one surface side of the silicon sheet is in a state of being pushed into the protruding portion of the package. However, the opposite side of the unevenness 03 portion on one surface side of the silicon sheet is a space. Due to this space, the pressure exerted on the protruding portion of the package by the uneven portion 03 on one surface side of the silicon sheet is less affected so as to be quasi-proportional to the protruding height.

Further, in the notch pattern, by providing a notch of V-shaped cut 06 as shown in FIG. 1, the shape of the rising tip is changed, the degree of ridge is adjusted, and the height of the height space is adjusted. It is also possible.

Due to the characteristics of silicon, it is possible to adjust the frictional resistance between the surface of the silicon sheet and the surface of the package by surface treatment of the surface of the silicon sheet, it is possible to select an antistatic material, and it is possible to perform heat treatment. It can also have the advantage of being washable.

By utilizing such an effect, electronic components having different outer shapes and heights can be commonly used, so that they can be used as a common general-purpose tray.

In addition, FIG. 10 and FIG. 11 show photographs of an example (prototype) using paper as the material of the cutting plate 20a.

Including these, the plate of the material to be the target of the cutting plate 20a may be a material containing at least any one of metal, fiber, resin, paper, silicon and rubber, depending on the intended use and the like.

(About manufacturing method)
The method for manufacturing the notch plate 20a includes, for example, the following steps.

As one step, the positions of the columns 17 of the divisions that divide the board into a plurality of columns 17 are determined as columns 17 along the vertical direction on the plate surface with respect to the predetermined pulling directions A01 and B02 of the plate as the material. It is a positioning process (positioning means).

As another step, there is a cutting step (cutting means) in which a plate is cut according to a predetermined cutting pattern shape and arrangement along the column 17 positioned by the positioning step.

In order to exhibit the features of the present invention, the notch may not be linear, but may have a different shape, for example, the shape of the notch may be an elongated hole.

Further, as a step of raising the unevenness 03 portion on one surface side of the cut plate 20a, the positioning step and the cut step are repeated for the number of rows of a plurality of columns 17, and then a raised protrusion is formed on the plate surface. A tensile step (tensile means) of pulling the plate in the predetermined tensile directions A01 and B02 with such a tensile tension may be further included.

As a manufacturing apparatus for the cutting plate 20a, for example, a blade pattern corresponding to the pattern shape is provided on one side of the pressing plate for cutting, and a groove corresponding to the blade is provided on the other side of the pressing plate. A method may be used in which a plate of the target material is pressed by the device to produce the notch plate 20a.

As a pressing method of the press device for making a cut, the shape of the side where the blade pattern corresponding to the pattern shape is provided in the press device and the other side where the groove corresponding to the blade is provided can be formed in a cylindrical shape other than a plate. Therefore, the shape of the press device and the method of making a notch (for example, making a notch by hand using a cutter) are not particularly limited.

Further, the cutting plate 20a manufacturing apparatus including the positioning means, the cutting means, and the pulling means described above may be used.
