JPS60121091A - Production of cut-out pattern by laser beam - Google Patents

Abstract

PURPOSE:To improve the quality of cut-out patterns and to increase the speed of production by brinding upper and lower stainless steel masks sandwiching thin materials into press contact with each other by electromagnets and cutting out the fine patterns to the material by a laser beam. CONSTITUTION:A suitable number of materials 6 to be cut out such as paper or the like are sandwiched between stainless steel mask plates 2, 3 formed preliminarily to a prescribed fine pattern. Pins 4 are fitted into pin holes 2', 3' and the cut out pattern parts 2a and 3a are superposed to fit the tips of the pins 4 into the fitting holes 1' of a base plate 1. Electromagnets 5 in the lower part of the plate 1 are operated and the plates 2, 3 are fixed to the materials 6 in tight contact therewith by the magnetic force thereof. A laser beam is then irradiated downward and perpendicularly to the plate 2 and the materials 6 are cut out to the same shape as the shape of the pattern 2a thereby forming the pattern. Large quantities of the fine patterns having good quality are quickly formed on the materials by the above-mentioned method.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of manufacturing a cutout pattern using a laser beam in the processing of a cutout pattern of cutout paper for arts and crafts or dyed haiku paper.

In recent years, using laser beams, mechanical and rapid
A processing method has been implemented in which fine patterns are cut, but several sheets of paper or other thin materials are stacked together, a metal pattern mask plate is placed on top of the paper, and a laser beam is scanned from above the mask plate. One method is to burn out the material and cut it out. In this case, it is necessary to securely adhere and fix the mask plate and the material, and the overlapped mask plate and material may become misaligned during laser beam scanning, or burnout may occur from the gap between the stacked materials. It is necessary to prevent smoke from entering.

The present invention is a processing method in which a mask plate is superimposed on the upper and lower sides of a cutout material and cut out using a laser beam.The mask plate and material can be securely fixed in close contact and cut out, and the cutout can be made accurately and finely. , it is possible to produce high-quality cutout patterns.

The present invention involves inserting a piece of paper or other thin material into a desired pattern between upper and lower metal mask plates made of stainless steel, and fitting a bottle into a pin hole provided at one end of the mask plate. The upper and lower patterns are aligned and placed and fixed on the base surface, and while the upper mask plate is pressed to the intermediate position by the magnetic force of the electromagnet installed at the bottom of the base, a laser beam is scanned on the upper mask plate surface to form the Kirishina surface. This is a method for manufacturing a cutout pattern using a laser beam, which is characterized by cutting out a fine pattern.

To explain the method of the present invention in more detail, FIG. 1 is a side view of an embodiment of the method of the present invention, in which (1) is a cutout pattern manufacturing base, (2) is an upper metal mask plate, and (3) is a cutout pattern manufacturing base. is the lower metal mask plate, (4) is the register bottle, (5) is the electromagnet, and (6) is the cutting material. First, an appropriate number of cutting materials (6), such as paper or film, are sandwiched between stainless metal mask plates of the same type (SUS403) that have been previously formed into a desired fine pattern, for example, one or more sheets. Insert the registration bottle (4) into the bottle hole +2 (L31) provided at one end of each of the mask plates +21 and G31.
).

Align the overlapping registration of the cutout pattern parts (2a) and (3a) in (3), place them on the cutout base (1), and insert the lower tip of the registration pin (4) onto the base (1). Fit into the fitting hole (white) and secure.

Next, operate the electromagnet (5) on the lower side of the base (1) and use its magnetic force (dashed line) to move the upper mask plate (2) downward.
The mask plate (2), the forest material (6) and the lower mask plate (
:3) and fix it on the base (1) surface. Next, the laser beam shown in FIG. 2 is irradiated vertically downward in the direction of the arrow to the surface of the upper mask plate (2), and the material (6) is cut out in the same shape as the cutout (turn γ11z (2a)) to form a pattern. .

In the method of the present invention, an electromagnet (5
) can be attached to ensure that the upper mask plate (2) and the monthly rate (5) are in close contact, and the finely patterned stainless steel mask part of the upper mask plate (2) is physically pressed by gravity. (It is possible to press the material evenly to the material surface by magnetic force, so the adhesion is accurate,
Because it is easy to operate, it is possible to quickly produce high-quality fine cutouts on materials such as paper, and it is extremely effective in producing cutout patterns formed by irradiating laser beams onto metal mask plates. .
