JPH04336524A - Laser decoration for glasses part - Google Patents

Abstract

PURPOSE:To provide the decoration of a glasses with a fine through hole pattern by forming a thin part on a glasses part, radiating laser beams with a prescribed pattern or printing a relief pattern and radiating laser beams at the thin part. CONSTITUTION:A thin part 11 is formed on a glasses article 1, and laser beams are radiated at a desired position of the thin part 11, and a through hole 12 having a prescribed shape is formed in a moment and used as a designed pattern. In other case, a relief pattern is printed on the glasses part, and laser beams are radiated on the thin part of the relief pattern, and the through hole 12 having a prescribed shape is formed in a moment and used as designed pattern. When a glasses is formed by using the glasses part 1, any complicated decoration pattern can be formed correctly. Since the opened position for the through hole is set at the thin part, the through hole 12 can be formed without heating the glasses part 1, and the deterioration of the quality of the part material due to the thermal history can be prevented.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for decorating eyeglass parts, and is particularly useful when decorating temple parts with through holes.

[0002] When it comes to decorating glasses, decorating them with rich colors can be too garish. Glasses are so conspicuous that they affect the impression of the face, so it is desirable that the change in color be suppressed if possible so as not to cause discomfort to others. However, if there is no decoration at all, it will give a cold and unfriendly feeling. The difficulty in designing glasses is that the decoration must suit the person's face, without being too flashy or plain.

[0003] Traditionally, a method of making transparent holes in the temples of glasses and using them to decorate the glasses has been commonly used, and it is expected that a sufficient decorative effect can be obtained without putting too much emphasis on coloring. There is. However, Japanese eyeglasses boast an extremely delicate structure, so even the slightest deviation may occur during manufacturing.
If the size of the hole becomes larger than designed or if the position of the hole shifts, the strength of the glasses may become insufficient.

[0004] Furthermore, in conventional mechanical drilling using presses, drills, etc., there are limits to the size and shape of holes and slits that can be created, and it is difficult to create patterns with complex shapes by crowding a large number of holes and slits. There was also the problem that it was not possible to form a

[0005]

SUMMARY OF THE INVENTION Accordingly, it is a technical object of the present invention to provide a means for decorating eyeglasses with through-holes by accurately making small holes or slits.

[0006]

[Means for Solving the Problems] In the present invention, a thin-walled portion is provided in an eyeglass component, and a laser beam is irradiated onto a desired position of the thin-walled portion to instantaneously form a through-hole of a predetermined shape to form a pattern. Alternatively, a method is adopted in which a relief pattern is imprinted on an eyeglass component, and a laser beam is irradiated onto the thin part of the relief pattern to instantly form a through hole of a predetermined shape to form the pattern, and this eyeglass component is used to create a pattern. The present invention provides a means for decorating eyeglasses that can accurately form any complicated decorative pattern.

[0007]According to this means, since the opening position of the through hole is determined in the thin part, the through hole can be opened without heating the eyeglass component too much, and the base material of the component is not altered due to thermal history. You don't have to worry about it happening. In other words,
In the case of resin parts, scorch marks will not be formed around the through hole, and in the case of metal parts, there will be no softening due to partial annealing. Furthermore, since the through holes are formed before the influence of heat propagates to the surroundings, it is also possible to form a large number of extremely small holes and slits. Therefore, it becomes possible to form delicate and complicated decorative patterns on the glasses. It goes without saying that laser processing also facilitates small-lot, multi-product production.

EXAMPLES The present invention will be explained below based on examples.

A temple component 1 made of stainless steel is manufactured by press molding. A portion of the temple component 1 is manufactured to be thin, and this portion forms a thin portion 11. After this temple part 1 is set in a laser beam generator (not shown), a carbon dioxide laser is irradiated onto a predetermined position of the thin wall portion 11, and a through hole 12 is opened. A plurality of positions for forming the through holes 12 are set in advance, and a laser beam generator (not shown) performs the drilling operation accurately according to the settings. In this way, as shown in FIG. 1, a temple component 1 decorated with a cloud-shaped pattern by the through holes is obtained. After that, if glasses are manufactured using this temple part 1, glasses with temples decorated with a large number of densely packed through holes can be obtained.

Separately, a temple component 1 made of stainless steel is press-molded to form a relief pattern on a portion thereof. After this temple part 1 is set in a laser beam generator (not shown), a carbon dioxide laser is irradiated onto the thin part of the relief pattern to open a through hole 12. In this way, a temple component 1 decorated with a cloud-shaped pattern as shown in FIG. 2 is obtained. After that, if glasses are manufactured using this temple part 1, glasses with temples decorated with a large number of densely packed through holes can be obtained.

Although the present embodiment has been described above, the present invention is not limited to the above embodiment, and various modifications can be made. For example, the material of the eyeglass parts may be changed, or It is also possible to add decorations to the glasses.

0012

As described above, according to the present invention, small holes and slits can be formed accurately, making it possible to freely decorate eyeglasses. Further, according to the method of the present invention, since the hole opening position is limited to the thin part, the decoration speed is fast and decorative eyeglass parts can be manufactured in a short time. Furthermore, if the hole opening position is limited to a thin part, the processing position and focus will easily match even when the laser is used as a condensed beam using a filter. As described above, the cosmetic method of the present invention makes it possible to apply delicate and complicated decorations to eyeglasses using the through holes, and has high industrial utility value.
