Abstract

PURPOSE: A method is provided to mark various colors an object using a laser regardless of sorts of the objects and to efficiently conduct a little marking. CONSTITUTION: An object(1) first removes impurities and moves to a marking position. A color film(10) is automatically supplied to the object by a transferring device(21) of a marking machine(20). The color film clings to the object by a mask(22) or a vacuum device(23). A black or brown heat absorbing film(30) is layered on the upper face of the color film. In this state, a laser is injected as a character or a pattern and an adhesive(11) of the color film is molten by the laser. Therefore, a color layer(12) is marked on the object, then a textile fiber(14) and a separating film are removed finally.

Description

레이저 칼라 마킹방법{Laser color marking method}Laser color marking method {Laser color marking method}

본 발명은 칼라 레이저 마킹방법에 관한 것으로서, 더욱 상세하게는 마킹대상 제품에 소망하는 칼라 필름을 밀착시킨 다음 문자 또는 문양화된 레이저를 주사시켜 칼라의 필름이 마킹대상물에 마킹되게 함으로써 마킹대상 제품의 재질에 상관 없이 다양한 칼라 마킹이 가능하게 한 칼라 레이저 마킹방법에 관한 것이다.The present invention relates to a color laser marking method, and more particularly, to a desired color film in close contact with a product to be marked, and then scanning a character or patterned laser to cause the film of the color to be marked on the marking object. The present invention relates to a color laser marking method that enables various color markings regardless of materials.

주지된 바와 같이, 각종 제품이나 금속, 그리고 반도체 등에는 그 제품을 표기하는 문자나 문양이 마킹되는데, 일반적인 마킹방법으로는 잉크 마킹, 실크 마킹, 패드 마킹, 마지막으로 레이저 마킹 등이 있으며, 특히 본 발명과 관련된 레이저 마킹방법은 약 10년전부터 본격적으로 도입되어 통신, 전자, 반도체를 비롯한 각종 분야에서 폭넓게 적용되고 있다.As is well known, various products, metals, semiconductors, etc. are marked with letters or patterns for marking the products, and general marking methods include ink marking, silk marking, pad marking, and finally laser marking. The laser marking method related to the invention has been introduced in earnest from about ten years ago and has been widely applied in various fields including communication, electronics, and semiconductors.

즉, 종래의 레이저 칼라마킹방법은 마킹대상 제품상에 레이저를 주사하여 그 열로서 음각하므로서 소망하는 문자나 문양을 마킹하게 된다.That is, in the conventional laser color marking method, a laser is scanned on a product to be marked and engraved as the heat, thereby marking a desired character or pattern.

그러나, 상기와 같은 종래의 레이저 마킹방법은 레이저의 열로써 태워 문자나 문양을 음각하는 것이기 때문에 내열성이 매우 약하거나 강한 재질등에는 사용이 불가능하여 극히 제한적으로 사용가능할 뿐만 아니라, 마킹대상 제품의 재질에 따라 소망하는 칼라색상이 표현되지 못하는 등의 문제점이 있었다.However, since the conventional laser marking method is to engrave letters or patterns by burning with the heat of the laser, it is impossible to use the material with very weak or strong heat resistance, and thus it is extremely limited and can be used. As a result, there was a problem that the desired color cannot be expressed.

따라서, 본 발명은 상기와 같은 문제점을 감안하여 창출한 것으로 마킹대상 제품에 소망하는 칼라 필름을 밀착시킨 다음 문자 또는 문양화된 레이저를 주사시켜 칼라의 필름이 마킹대상물에 점착 마킹되게 함으로써 마킹대상 제품의 재질에 상관 없이 다양한 칼라 마킹이 가능하게 하는 동시에 마킹대상 제품에 마킹하기가 매우 용이하므로 소량의 마킹작업도 효과적으로 할 수 있는 칼라 레이저 마킹방법을 제공함에 그 목적이 있다.Therefore, the present invention has been created in view of the above problems, and the desired product is marked by close contact with the desired color film on the product to be marked, followed by scanning a letter or patterned laser to make the film of the color adhesively marked on the object to be marked. It is an object of the present invention to provide a color laser marking method that enables a variety of color markings regardless of the material of the material and at the same time it is very easy to mark the target product.

이하, 본 발명의 일실시예를 첨부된 도면에 의거하여 상세히 설명하면 다음과 같다.Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명에 따른 마킹방법의 공정도이다.1 is a process diagram of a marking method according to the present invention.

먼저, 마킹대상 제품(1)이 마킹위치에 정확히 위치하게 되면, 열형 접착제 (11)가 도포되고, 그 상면에 칼라층(12)이 형성되며, 상기 칼라층(12)의 상면에 이형필름(13)과 원단(14)이 차례로 적층된 칼라 필름(10)이 마킹장치(20)의 이송수단 (21)에 자동으로 공급됨과 동시에 마킹대상 제품(1)에 마스크(22) 또는 진공수단 (23)에 의해 칼라 필름(10)이 밀착된다. 이때, 상기 칼라 필름(10)의 상면부에는 흑색이나 갈색의 열흡수필름(30)이 적층된다.First, when the product to be marked 1 is correctly positioned at the marking position, the thermal adhesive 11 is applied, and a color layer 12 is formed on an upper surface thereof, and a release film is formed on an upper surface of the color layer 12. 13 and the fabric 14 are sequentially stacked, the color film 10 is automatically supplied to the conveying means 21 of the marking device 20 and at the same time the mask 22 or the vacuum means 23 to the product to be marked 1. The color film 10 is in close contact with each other. In this case, a black or brown heat absorbing film 30 is stacked on the upper surface of the color film 10.

그런 다음, 상기 마킹대상 제품(1)에 칼라 필름(10)이 밀착된 상태에서 열흡수필름(30)이 적층된 다음 문자나 문양으로 레이저가 주사되는데, 이때 레이저의 열과 주파수에 의해 칼라 필름(10)의 열형 접착제(11)가 녹아 칼라층(12)이 마킹대상 제품(1)상에 마킹된다.Then, the heat-absorbing film 30 is laminated in the state in which the color film 10 is in close contact with the product to be marked 1, and then the laser is scanned by a letter or a pattern. The thermal adhesive 11 of 10) melts and the collar layer 12 is marked on the product to be marked 1.

본발명의 작용 및 효과를 설명하면 다음과 같다.Referring to the operation and effect of the present invention.

레이저를 이용한 칼라마킹의 공정을 상세히 설명하면, 도 1과 같이 이물질이 제거된 마킹대상 제품(1)이 마킹위치에 정확히 위치하게 되면, 칼라 필름(10)이 마킹장치(20)의 이송수단(21)에 자동으로 공급된다.Referring to the process of color marking using a laser in detail, as shown in FIG. 1, when the marking target product 1 from which foreign substances have been removed is accurately positioned at the marking position, the color film 10 is transferred to the marking device 20 ( 21) automatically supplied.

이와 동시에 마킹대상 제품(1)에 마스크(22) 또는 진공수단(23)에 의해 칼라 필름(10)이 밀착되는데, 이때 상기 칼라 필름(10)의 상면부에는 흑색이나 갈색의 열흡수필름(30)이 적층된다.At the same time, the color film 10 is in close contact with the product to be marked 1 by the mask 22 or the vacuum means 23. At this time, the upper surface of the color film 10 is a black or brown heat absorbing film 30. ) Are stacked.

상기 마킹대상 제품(1)에 칼라 필름(10)이 밀착된 상태에서 열흡수필름(30)이 적층된 다음 문자나 문양으로 레이저가 주사되는데, 이때 레이저의 열과 주파수에 의해 칼라 필름(10)의 열형 접착제(11)가 녹아 칼라층(12)이 마킹대상 제품(1)상에 마킹되며, 이때 원단(14) 및 이형필름(13)이 제거된다.The heat absorbing film 30 is laminated in the state in which the color film 10 is in close contact with the product to be marked 1, and then a laser is scanned by a letter or a pattern, wherein the laser film is heat and frequency of the color film 10. The thermal adhesive 11 is melted, and the color layer 12 is marked on the product to be marked 1, at which time the fabric 14 and the release film 13 are removed.

따라서 본 발명은 마킹대상 제품(1)에 소망하는 칼라 필름(10)을 밀착시킨 다음 문자 또는 문양화된 레이저를 주사시켜 칼라 필름(10)이 마킹대상 제품(1)에 점착 마킹되게 함으로써 마킹대상 제품(1)의 재질에 상관 없이 다양한 칼라 마킹이 가능한 동시에 마킹대상 제품에 마킹하기가 매우 용이하므로 소량의 마킹작업도 효과적으로 할 수 있는 매우 유용한 효과 있다.Therefore, in the present invention, the desired color film 10 is brought into close contact with the product to be marked 1, and then a character or patterned laser is injected to make the color film 10 adhesively mark the product 1 to be marked. Regardless of the material of the product (1), various color markings are possible, and at the same time, it is very easy to mark the product to be marked, and thus a small amount of marking work can be effectively used.
