Abstract

PROBLEM TO BE SOLVED: To upgrade an accuracy of a character or a design by coating a workpiece with a paint or vapor depositing a metal, baking it, then irradiating it with a laser beam, releasing only a coated material or a vapor deposited material, and forming a fluorescent reflecting surface. SOLUTION: A surface 2a of a workpiece 1 made of light transmitting transparent acrylic resin, glass or the like is coated with a pigment, an ink or the like or vapor deposited with a metal powder to execute a coating surface or a vapor depositing material 2, and then baked. Thereafter, the front surface 1a or the rear surface 1b side of the workpiece 1 is irradiated with a laser beam 5. The material 2 such as the previously coated coating material, previously vapor deposited metal powder or the like is removed by releasing, and a character or a design is drawn without damaging the workpiece 1 of a base material. Then, a back surface of the drawn surface of the workpiece 1 is coated with a phosphorescent material or a fluorescent film, a phosphorescent film is adhered to form a fluorescent reflecting surface 3. Further, a metal plate 4 is fixed to the rear side of the surface 3 with an adhesive, a screw or the like.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to decoration of signboards, nameplates, elevators, panels, doors, interior and exterior, POPs, signs, objects, monuments, ships, vehicles, motorcycles, hotel information boards, nameplates, necklaces, and pendants. The present invention relates to a method for drawing characters and patterns on a workpiece used for articles and the like, and more particularly to a method for drawing characters and patterns on a workpiece such as an acrylic resin, glass, or glass tableware.

[0002]

2. Description of the Related Art A conventional drawing method is to draw a picture or a character by forming a mold of glass with rubber and generating fine chipping on the glass surface with sand, or an acrylic resin is used.
Cut out patterns and letters on metal and paste them on acrylic resin.
Acrylic resin and glass were then attached to the back of the lighting fixture so that the characters could be read even at night.

[0003]

However, in the prior art described above, first, the glass has a defect that the surface is scratched, the strength is deteriorated, and the glass at the chipping is fogged. The acrylic resin has been stuck to metal or inserted and inserted into the metal, and a method for commercialization has been adopted, but all of them require lighting equipment. For this reason, there were many processing steps such as unreachable high places, electric construction costs, signs for emergency evacuation sites for maintenance, and metal signboards that required maintenance in several years.

SUMMARY OF THE INVENTION In view of the above problems, the present invention is capable of accurately displaying characters and pictures or patterns on the front and back surfaces of a workpiece without deterioration over time and requiring no maintenance for both day and night. It is intended to provide products that are made and have no chipping deterioration.

[0005]

Means for Solving the Problems A paint is applied to the front or back surface of a light-transmitting workpiece made of acrylic resin, glass, or the like, or a metal is vapor-deposited and baked, and then the surface of the workpiece is coated. Or, irradiate a laser beam from the back side, without damaging the workpiece to be the base material, peeling off only the coating material or the vapor deposition material, draw letters, pictures and patterns, and fluoresce and phosphorescent material on the drawn back face Alternatively, the present invention is a method for drawing a character or a picture, characterized in that a fluorescent reflecting surface is formed by applying or attaching a film, and a metal plate is fixed to the fluorescent reflecting surface.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described with reference to FIGS. Reference numeral 1 denotes a workpiece, which is a base material. The workpiece 1 is a transparent acrylic resin or glass, as shown in FIGS. 1A and 3A, a pigment on the surface 1a of the workpiece 1, An ink, a paint, a glaze, or the like is applied, or a metal powder is vapor-deposited, and the application surface or the vapor deposition material 2 is applied. Next, FIG.
The printing process is performed as shown in FIG. Then, as shown in FIG. 1 (C), a laser beam 5 is irradiated from the front surface 1a or the back surface 1b side of the workpiece 1, and pigments, inks, paints, glazes, coating materials and metals which have been applied or deposited in advance. Powder deposition material 2
Are removed and characters, pictures and patterns are drawn without damaging the workpiece 1 as a base material. Next, as shown in FIG. 1 (D), a fluorescent material or a phosphorescent material is applied to the back of the surface on which the workpiece 1 is drawn, or a fluorescent film or a phosphorescent film is attached to form the fluorescent reflecting surface 3. Further, as shown in FIG. 1E, a metal plate 4 is fixed to the back side of the fluorescent reflecting surface 3 by an adhesive or a screw.

More specifically, as shown in FIG. 2 as a drawing method, for example, characters, numbers, symbols or patterns to be drawn,
Draw a pattern with the CAD system 10 and draw it on the floppy
Inputting to a disk (hereinafter referred to as “FD”), inserting the FD into the control device main body 12 of the drawing device main body 11, and calculating the processing conditions and the FD drawing of the laser beam to be drawn on the workpiece 1 in advance. The signal is sent to the
When the Y table 14 is operated, the laser beam 5 oscillated from the laser oscillator 13 at the same time as the surface 1a of the workpiece 1
Alternatively, it is a method of irradiating from the back surface 1b and drawing characters, pictures, patterns, etc., without soiling the surface, without causing the surface to be stained by the reflected heat from the coating surface or the evaporation surface 2 and the irradiation light from the surface. . Reference numeral 15 denotes a laser device main body, and 16 denotes a scanning system.

Next, a second embodiment of the present invention will be described with reference to FIG. This embodiment is an example in which a back surface 1b of the workpiece 1 is coated with a pigment, ink, paint, glaze, or the like, or an application surface or a vapor deposition surface 2 on which metal powder is deposited is formed only on the back surface. Other configurations are the same as in the first embodiment.

Further, a coated surface or a vapor-deposited surface is coated on the surface of the workpiece 1 made of acrylic resin, glass, or the like.
An undercoat may be applied to facilitate deposition, and a top coat may be applied for reinforcement.

[0010]

As is apparent from the above description, according to the method for drawing characters and patterns of the present invention, the pigment, pigment and the like are not damaged on the base material such as acrylic resin and glass.
Numbers, symbols, characters, pictures, and patterns can be drawn simply and easily by removing only coating materials such as inks and paints, or vapor deposition materials.Furthermore, there is no rust, etc. It is possible to obtain an inexpensive drawing method that is safe and has high visibility both day and night.
