Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 In the present invention, a desired design is formed on the workpiece by irradiating a laser beam output from the laser cutting device to form a non-penetrated hole formed to a predetermined depth of the workpiece. Regarding the applied laser non-cutting card.

[0002]

[Prior art]

 Conventionally, a laser beam output from a laser oscillator is appropriately reflected or diffracted by an optical element to form a small spot of a laser beam on the surface of a workpiece, and the workpiece or the beam spot is sequentially moved. Laser cutting devices and methods for melting or evaporating a part of the workpiece (hereinafter, simply referred to as “melting or the like”) to separate the workpiece into two or more parts have been implemented in the industry.

FIG. 6 shows an example of a conventional laser cutting method. That is, the laser beam 62 output from the laser oscillator enters the optical element 61 including a condenser lens and the like. The laser beam 62 converged by the optical element 61 forms a minute beam spot 63 on the surface of the workpiece B. Such a beam spot 63 is a point at which the so-called power density is increased. When the portion irradiated with the beam spot 63 is melted or the like, the melted portion penetrates. By repeating the above steps, the workpiece is cut and separated.

[0004] In particular, regarding the cutting of the workpiece when the workpiece is paper, unlike the cutting method using a tool, the laser cutting method is a non-fusing method, so that the laser cutting method is unnecessary for the paper being cut. It is possible to cut the paper without damaging the aesthetic appearance of the cut without applying excessive force. As a result, a part of the workpiece is melted by the laser beam or the like, and as a result, a hole cut into a complicated shape is formed by utilizing the fact that the illuminated part penetrates and forms a hole. Paper is obtained. By appropriately forming a hole cut out in this complicated shape, a greeting card designed with a tree or house shape, that is, a so-called laser cutting paper product is provided.

[0005]

[Problems to be solved by the invention]

 However, first, since the workpiece obtained by the above laser cutting device is generally cut, the laser cutting device can be used for purposes other than cutting the workpiece. could not. For this reason, there has been strong expectation from interested parties that a novel product (article) that can open up a new industrial field by applying the laser cutting device will be devised and developed.

[0006] Furthermore, as an example in the printing processing industry where the workpiece is not cut or separated, a laser beam penetrates the workpiece by a conventional laser cutting method to form a hole. There is a product called the laser cutting card, in which holes of various shapes are provided in the paper by utilizing the property described above and a certain design is provided. However, since the processed object (laser cutting card) in a finished state has holes formed in a honeycomb shape, the strength is extremely poor due to the fact that the processed object is originally paper. As a result, it has been pointed out that the laser cutting card itself is often damaged, depending on the force of holding the laser cutting card itself by hand, so that it is difficult to handle.

Further, since the back side of the laser-cutting card itself, particularly the back side of the hole with the design, is completely penetrated, for example, a message on the back side of the place with the design formed by the hole is provided. Since it was almost impossible to attach a small piece of paper or write characters on it, it was extremely low in utility because its use was limited to design.

[0008]

[Means for Solving the Problems]

 Therefore, as a result of intensive research, the inventor of the present invention has developed a laser non-cutting card or the like, characterized in that a hole formed by melting by laser beam irradiation is provided in a part of the workpiece. As a result, holes of various depths can be formed in a part of the workpiece by applying the laser cutting device or the like. As a result, it is possible to penetrate the workpiece by applying the laser cutting device or the like. This makes it possible to apply complex designs without the use of holes that have been made, so that it has a completely new and aesthetic property that has never existed before, and has an extremely useful value that can be used to write messages. This makes it possible to provide a product (laser non-cutting card) composed of a workpiece having no high-perforated or penetrated or cut holes. The details will be described below with reference to the drawings.

[0009]

[Embodiment of the invention]

 FIG. 1 shows a laser non-cutting card (hereinafter, referred to as a “card”) according to the present invention, which has a cutout pattern in appearance, and the pattern is irradiated with a laser beam 2 to a workpiece A, and the workpiece is processed. It is formed by a hole formed by melting a part of the body A.

Specifically, FIG. 1 shows a cross section of a part of the card provided with the hole, and the workpiece A is so deep that it does not penetrate by the irradiation of the laser beam 2. Some of them are molten. The hole formed in this way makes the workpiece A concave and convex. The irregularities can be visually recognized as a pattern by a viewer. For example, a wavy pattern D1 and an elliptical pattern D2 are formed on the workpiece A. The card according to the present invention includes at least the workpiece A and the hole.

FIG. 3 shows a laser cutting method applicable to the manufacture of the card according to the present invention. FIG. 3A shows a laser cutting method using a so-called beam scanning method. The laser beam 2 condensed by the optical element 8 such as a lens is reflected by the rotary reflecting mirror 3. The reflected laser beam 2 forms a focused beam spot on the workpiece A by controlling the movement of the rotary reflecting mirror 3 in the X-axis direction and the Y-axis direction. Such a beam spot is a point where the power density of the laser beam 2 is concentrated. At this point, the workpiece A is melted or the like, so that the hole 5 is formed.

More specifically, the movement of the rotary reflecting mirror 3 is controlled, or the work A is controlled to move in the X-axis direction or the Y-axis direction, or both of them. The body A has many holes 5 formed therein. As a result, the continuously formed holes 5 can form the groove-shaped holes 5 in the workpiece A or the minute holes 5. At this time, in order to prevent the laser beam 2 from penetrating the workpiece A, the speed at which the rotary reflecting mirror 3 or the workpiece A is moved and the time for irradiating the laser beam 2 are appropriately determined. , The power density of the beam spot is adjusted.

It is preferable to select a laser beam 2 that is easily absorbed by the material of the workpiece A. Although the optical element 8 is not essential for manufacturing the card according to the present invention, it is generally difficult to obtain a high power density with the laser beam 2 output from the laser oscillator. In such a case, the laser beam 2 is condensed by using the optical element 8 to improve the power density.

Next, FIG. 3B shows a so-called mask system which is also applicable to the manufacture of the card according to the present invention. A laser beam 2 emitted from a laser oscillator (not shown) passes through a mask 4. The mask 4 is made of a predetermined pattern or a thin metal plate (mask) in which a pattern is cut out, but the material is not limited. The laser beam 2 is condensed by the optical element 8 and forms an image on the surface of the workpiece A, so that a part of the workpiece A can be melted by burning.

The hole 5 may be formed in the workpiece A by closely fixing the mask 4 on the surface of the workpiece A and scanning the laser beam 2 at regular intervals.

Hereinafter, embodiments will be described. FIG. 4 is a sectional view of the card according to the first embodiment of the present invention. In this embodiment, the workpiece A is a four-layer laminate 1 composed of colored papers 1a, 1b, 1c, and 1d colored in different colors. Here, the “colored paper” in this example is a paper in which the same dye is impregnated into the entire paper, and the “laminated body” is one in which at least two layers are fixed together, and the “fixed” is the layer. Any method of joining the two may be included, and in particular, an adhesive or an adhesive-impregnated support may be used.

When the rotary reflecting mirror 3 is at the position A, the laser beam 2 emitted from a laser oscillator (not shown) forms a beam spot toward the laminate 1 by the rotating reflecting mirror 3. Such a beam spot starts melting from the surface of the laminate 1. By irradiating the laser beam 2 for an appropriate time, melting or the like is stopped at the colored paper 1d on the way without penetrating the laminate 1. As a result, the color of the colored paper 1d is recognized by the viewer through the hole 5. Here, the “front surface” refers to the surface of the laminate 1 (or the workpiece A) on which the laser beam 2 is irradiated. Therefore, in this specification, the “back surface” refers to a surface on the opposite side of the front surface.

Similarly, when the rotary reflecting mirror 3 is at the position B, by appropriately adjusting the irradiation time of the laser beam 2, the depth of the hole 5 is set to such a degree that the hole 5 does not penetrate the colored paper 1 a. It can also be formed to a depth. Through the hole 5 thus formed, the color of the colored paper 1a is recognized by the viewer. Hereinafter, when the rotary reflecting mirror is at the position C, the hole 5 does not penetrate the colored paper 1b so that the color of the colored paper 1b can be recognized by adjusting the irradiation time of the laser beam 2. To a depth of. Similarly, in the case of the position D of the rotary reflecting mirror 3, the hole 5 is formed to a depth that does not penetrate the colored paper 1c. Accordingly, in this case, a maximum of four colors are recognized by the viewer, and as a result, a design card composed of four colors can be obtained.

Next, a second embodiment of the present invention will be described. In the present embodiment, the workpiece A is a paper whose surface is colored only, and is referred to as “surface colored paper”. As shown in FIG. 5, the surface colored paper 6 has a colored layer 6a which is a colored surface layer and a color other than the color of the surface layer (the most common color is white of the original color of the paper). And a primary color layer 6b having

In FIG. 5, when the rotary reflecting mirror 3 is at the position F, the irradiation time of the laser beam 2 is adjusted so that the bottom surface of the hole 5 still remains in the colored layer 6 a. In this case, through the hole 5 at the position F, the viewer recognizes the recess as a recess of the same color as the coloring layer 6a, and the recess can also be a component of the design.

On the other hand, when the rotary reflecting mirror 3 is at the position E, G, or H, the primary color layer 6 penetrates at least the coloring layer 6 a regardless of the depth of the bottom of the hole 5 formed. By performing melting or the like until the color reaches 6b, the color of the primary color layer 6b can be recognized. Therefore, in this case, as a result of the viewer recognizing a maximum of two colors,

Next, a third embodiment is shown in FIG. In the present embodiment, the workpiece A may be any one of the laminate 1 and the surface colored paper 6 used in the above-described first or second embodiment, and here, one workpiece A is used. It is described as paper. FIG. 2A is a front view of the card after the hole 5 has been formed in the workpiece A. FIG. As described in the first embodiment or the second embodiment, the time for irradiating the laser beam 2 to the surface of the workpiece A is appropriately adjusted on the surface of the card, and the workpiece A is Designed to prevent penetration.

As shown in FIG. 2B, a message entry field 7 is provided on one side of the back side of the surface having the design. The message entry field 7 is a field that can be written with a pen or the like that can be used when the card of the present invention is used as a message transmission medium for gifts, greetings, etc., and is particularly provided on the back side of the hole 5 with a design. The message description column is also provided on the back surface of the workpiece A located, and a frame may be described around the column, or nothing may be left blank.
