本発明は透光性を有するプラスチックシート１にアルミ
ニウム、錫等の金属箔シート２を張設した素材シート３
にレーザー光４を照射して照射箇所の金属箔を溶融飛散
除去せしめる金属箔積層シートの加工法に係る。DETAILED DESCRIPTION OF THE INVENTION The present invention provides a material sheet 3 in which a metal foil sheet 2 of aluminum, tin, etc. is stretched over a translucent plastic sheet 1.
The present invention relates to a method of processing a metal foil laminated sheet in which the metal foil at the irradiated area is melted and scattered by irradiating the laser beam 4 to the metal foil.
従来にあつては、単に一条のレーザー光４を一時に照射
するのみであつたので、レーザー光４の光束が太い場合
にはレーザー光４を照射した周辺部レーバリ５が発生し
やすいという欠点があつた。Conventionally, only a single ray of laser light 4 was irradiated at once, so if the beam of the laser light 4 was thick, there was a drawback that damage 5 to the peripheral areas irradiated with the laser light 4 was likely to occur. It was hot.
本発明は上記欠点を除去せんとするものであり、その要
旨とするところは、金属箔を除去せんとする箇所の外周

箔を光束の太いレーザー光４ａで除去することを特徴と
する金属箔積層シートの加工法である。The present invention aims to eliminate the above-mentioned drawbacks, and its gist is to form narrow grooves 6 by irradiating the outer periphery of the area where the metal foil is to be removed with a laser beam 4b having a narrow beam. This method of processing a metal foil laminated sheet is characterized in that the metal foil in the area surrounded by the narrow grooves 6 is then removed using a laser beam 4a with a large beam.
以下本発明を第１図乃至第 図に図示せる一実施例に基
づいて説明する。The present invention will be explained below based on an embodiment shown in FIGS.

光束の細いＱスイッチＹＡＧレーザー光４をで二条の平
行な細溝６を設ける。The aluminum foil is removed from the material sheet 3 to form wide grooves 7 as shown in FIG. 3 in the following manner. First, two parallel thin grooves 6 are formed on the outer periphery (in this case, both side edges) of the wide groove 7 using a Q-switched YAG laser beam 4 with a narrow luminous flux.
次に光束の太いＹＡＧレーザー光４ａを用いて細溝６間
のアルミニウム箔を除去する。Next, the aluminum foil between the narrow grooves 6 is removed using a YAG laser beam 4a with a large luminous flux.
ＹＡＧレーザー光４ａを使用するのは他の種類のレーザ
ー光に比べて透光性プラスチックを透過しやすいからで
ある。The reason why the YAG laser beam 4a is used is that it can more easily pass through transparent plastic than other types of laser beams.
而して叙上の如き操作により巾広い溝７が外周部にばり
等を発生させることなくきれいに精度よく形成できるの
である。Thus, by the operations described above, the wide groove 7 can be formed neatly and accurately without causing burrs or the like on the outer periphery.

く金属箔の除去ができるのである。Since narrow grooves 6 are formed on the outer periphery, the laser beam 4b is applied to the aluminum foil between the narrow grooves 6 in order to form wide grooves 7.
When attempting to irradiate and remove the laser beam 4b, the heat irradiated by the laser beam 4b is blocked by the narrow groove 6 and is difficult to escape to the surroundings.
Since there is little heat loss, it can be removed efficiently and in a short time without generating burrs or the like. Note that the narrow grooves 6 are provided when the material sheet 3 has aluminum foil sheets 2 stretched on both sides as shown in the example shown, and when it is necessary to provide the grooves 7 on both sides, the narrow grooves 6 are formed. It is preferable to irradiate each laser beam 4b separately in order to reduce thermal effects, but Q-switch YAG laser beam 4b
Since the heat effect is small when using the irradiation method, both sides can be processed simultaneously by irradiating from one side as shown in FIG. As described above, the method of processing a metal foil laminated sheet according to the present invention is to apply a narrow laser beam 4b to the outer periphery of the area where the metal foil is to be removed.
A thin groove 6 is formed by irradiating the metal foil with a thick laser beam 4a.
The heat added by the laser beam irradiated to the metal foil to be removed is blocked by the narrow grooves and is efficiently transmitted to the metal foil to be removed without escaping. Metal foil can be removed without creating burrs or the like.
