Description
본 발명은 레이저 마킹에 의한 칼라 형성방법에 관한 것으로, 특히 피가공물과 대비되는 색조로 문자나 도형을 마킹함으로써 그 문양을 명확히 구별할 수 있도록 한 것이다.The present invention relates to a method for forming a color by laser marking, and in particular, it is possible to clearly distinguish the pattern by marking a character or a figure in a color tone contrasted with the workpiece.
일반적으로 피가공물, 예를 들면 금속, 세락믹 또는 목재의 표면상에 회사 표시, 물품명, 제조 일자 또는 기타 특정 문자나 도형 등을 마킹하는데 있어서, 여러개의 문자나 기호를 그 표면상에 전사하거나, 마크되어 있는 문자나 기호를 따라 레이저빔을 주사하는 것에 의해 피가공물의 표면에 특정 활자를 마킹하는 여러 방법이 제안되었다.In general, in marking a company mark, article name, date of manufacture or other specific characters or figures on the surface of a workpiece, for example a metal, ceramic or wood, several characters or symbols may be transferred onto the surface, Several methods have been proposed for marking specific typefaces on the surface of workpieces by scanning laser beams along marked letters or symbols.
이와 같은 마킹방법에 따라 버클이나 열쇠고리 등에 특정 문자나 모양을 마킹하여 심미감을 향상시키게 되는데, 종래에는 레이저빔을 이용하여 금속의 표면상에 활자를 마킹하는데 있어서, 대상이 되는 금속이 흰색 종류일 경우에는 피가공물과 문자나 도형의 구별이 용이하지 않아 단조로울 뿐만 아니라 그 효과가 미비한 문제점이 있었다.According to the marking method, a certain character or shape is marked on the buckle or key ring to improve the aesthetics. In the past, the type of the target metal is white in marking the type of metal on the surface of the metal using a laser beam. In this case, it is not easy to distinguish between the workpiece and the character or figure, and there is a problem that the effect is insignificant.
본 발명은 이러한 문제점을 해결하기 위한 것으로, 피가공물의 표면에 마킹되는 문자 또는 도형이 그 피가공물과는 대비되는 독특한 색조를 띄도록 하여 피가공물로부터 문자 또는 도형이 명확히 구별될 수 있도록 한 레이저 마킹에 의한 칼라 형성방법을 제공하는데 그 목적이 있다.SUMMARY OF THE INVENTION The present invention has been made to solve such a problem, and laser marking is made so that the characters or figures marked on the surface of the workpiece have a distinctive color tone that contrasts with the workpieces so that the characters or figures can be clearly distinguished from the workpiece. It is an object to provide a method for forming a collar by.
상기 목적을 달성하기 위한 본 발명은 제조 완료된 금속 피가공물의 표면에 소정 두께로 피막을 입히는 피막처리단계와, 피막 처리된 피가공물의 표면에 레이저빔을 주사하여 원하는 형태의 문자나 도형을 형성하는 마킹단계와, 레이저빔을 주사하여 소정 깊이로 식각된 부분에 탈색제를 도포하는 탈색제 도포단계로 이루어진 것을 특징으로 한다.The present invention for achieving the above object is a film treatment step of coating a film with a predetermined thickness on the surface of the finished metal workpiece, and scanning the laser beam on the surface of the coated workpiece to form a character or figure of the desired shape A marking step and a decolorant coating step of applying a decolorant to the portion etched to a predetermined depth by scanning a laser beam, characterized in that consisting of.
이하, 본 발명에 의한 레이저 마킹에 의한 칼라 형성방법을 첨부도면에 도시한 실시예에 따라 설명하면 다음과 같다.Hereinafter, a method of forming a collar by laser marking according to the present invention will be described according to the embodiment shown in the accompanying drawings.
본 발명의 레이저 마킹에 의한 칼라 형성방법은 피막처리단계와, 마킹단계와, 탈색제 도포단계로 이루어진다.The method for forming a collar by laser marking of the present invention comprises a coating treatment step, a marking step, and a decolorant coating step.
상기 피막처리단계는 제조 완료된 금속 피가공물의 표면에 소정 두께로 피막을 입히는 단계로서, 피가공물이 쉽게 부식되는 것을 방지함과 아울러 피가공물에 광택 효과를 부여하도록 한다.The coating treatment step is to coat the surface of the finished metal workpiece with a predetermined thickness, to prevent the workpiece from being easily corroded, and to impart a gloss effect to the workpiece.
상기 마킹단계는 피막 처리된 피가공물의 표면에 레이저빔을 주사하여 원하는 형태의 문자나 도형을 식각하는 단계이다.The marking step is a step of etching a character or a figure of a desired shape by scanning a laser beam on the surface of the workpiece to be processed.
이와 같이 레이저를 이용하여 피가공물을 마킹하는 방식에는 통상적으로 마스크방식과, 주사방식으로 구분할 수 있는데, 상기 마스크방식은 원하는 패턴 부분만 레이저빔을 투과시키거나 반사시키는 마스크를 제작한 후 이를 광경로에 배치하여 한 번의 조사로 패턴을 마킹하는 방식이고, 주사방식은 저장된 패턴의 데이터에 따라 지정된 좌표로 레이저빔을 편향시켜 펜으로 그림을 그리듯 패턴을 마킹하는 방식이다.As described above, a method of marking a workpiece using a laser can be classified into a mask method and a scanning method. The mask method uses a light path after fabricating a mask that transmits or reflects only a desired pattern portion of a laser beam. It is a method of marking a pattern by one irradiation by placing it in the scanning method. The scanning method is a method of marking a pattern as if drawing with a pen by deflecting a laser beam at a specified coordinate according to the stored pattern data.
상기 탈색제 도포단계는 레이저빔을 조사하여 소정 깊이로 식각된 부분에 탈색제를 도포하는 단계로서, 식각된 부분에 탈색제가 도포되면 그 부분이 부식되면서 금속 본래의 색이 아닌 다른 색으로 변색된다. 이와 같이 문자나 도형에 형성된 색이 피가공물의 색과 대비되는 색으로 마킹되므로 피가공물로부터 마킹된 도형이나 문자의 구별을 명확히 할 수 있을 뿐만 아니라 피가공물에 대한 심미감을 향상시킬 수 있게 된다.The decolorizing agent applying step is a step of applying a decolorizing agent to the portion etched to a predetermined depth by irradiating a laser beam, when the decolorizing agent is applied to the etched portion is corroded to discolor the color other than the original color of the metal. Thus, since the color formed on the character or figure is marked with a color contrasted with the color of the workpiece, the distinction of the figure or character marked from the workpiece can be clarified and the aesthetics of the workpiece can be improved.
이때, 상기 탈색제의 원료를 변경함으로써 피가공물에 마킹되는 문자나 도형의 색을 원하는 색으로 변경할 수 있음은 물론이다.In this case, it is a matter of course that the color of the character or figure marked on the workpiece can be changed to a desired color by changing the raw material of the decolorant.
이상에서 설명한 바와 같이, 본 발명에 의하면 레이저빔에 의해 식각된 부분에 탈색제를 도포함으로써 피가공물의 표면에 마킹되는 문자 또는 도형이 그 피가공물과는 대비되는 독특한 색조를 띄도록 하여 피가공물로부터 문자 또는 도형의 구별이 명확히 이루어지도록 하며, 아울러 피가공물에 대한 심미감을 향상시킬 수 있게 된다.As described above, according to the present invention, by applying a bleaching agent to the portion etched by the laser beam, the character or figure marked on the surface of the workpiece has a unique color tone that contrasts with that of the workpiece, and thus the character from the workpiece. Alternatively, the distinction of figures can be made clearly, and the aesthetics of the workpiece can be improved.
