1 : 하우징 11 : 용융부1 housing 11 melt part

2 : 렌즈(제1 렌즈) 21 : 볼록부2: lens (first lens) 21: convex portion

3 : 제2 렌즈 31 : 오목홈3: second lens 31: concave groove

본 발명은 콤비네이션 램프의 렌즈와 하우징 용착시 레이저가 투과되는 제1렌즈 부위에 빔이 집중되도록 하는 볼록부 형상을 설정함으로써, 하우징에 열전달 시간을 단축하여 가공 사이클 시간을 단축시켜 가공비를 줄이도록 하는 레이저 용착 구조에 관한 것이다.The present invention sets the convex portion to focus the beam on the first lens portion through which the laser is transmitted when welding the lens of the combination lamp and the housing, thereby shortening the heat transfer time in the housing to shorten the processing cycle time to reduce the processing cost. The present invention relates to a laser welding structure.

종래에 콤비네이션 램프의 하우징과 렌즈를 결합하는 구조로 열판용착과 진동용착이 있었다. 그러나 이들 방식은 용착부에 버(burr) 나 더미부가 증가하는 외관문제, 그리고 디자인 자유도가 낮은 한계가 있었다.Conventionally, there has been hot plate welding and vibration welding in a structure in which a housing and a lens of a combination lamp are combined. However, these methods were limited in appearance problems with increased burrs or piles at welds, and low design freedom.

또한 콤비네이션 램프의 하우징과 렌즈를 결합하는데 있어서 레이저 용착구조도 사용되고 있다. 도 1은 종래의 콤비네이션 램프의 레이저 용착 구조에 대한 설명도이다. 레이저 용착 구조는 일정한 두께와 단면을 가진 렌즈(2)에 레이저 빔을 가해 하우징(1)이 용해되어 용융부(11)가 팽창하면 렌즈로 열전달이 이루어짐으로써 하우징과 렌즈가 부착되는 구조였다.Also, a laser welding structure is used to combine the housing and the lens of the combination lamp. 1 is an explanatory diagram of a laser welding structure of a conventional combination lamp. The laser welding structure was a structure in which the housing and the lens were attached by heat transfer to the lens when the housing 1 was melted and the melted portion 11 expanded by applying a laser beam to the lens 2 having a constant thickness and cross section.

이러한 레이저 방식은 종래의 열판용착이나 진동용착에 비해 외관이 개선되고 용착 싸이클 타임도 개선되지만, 부대장비가 필요하고 장비가 고가이기 때문에 용착 시간 단축이 곧 가공비에 영향을 미치는 방식이다.This laser method improves the appearance and the welding cycle time compared to the conventional hot plate welding or vibration welding, but because the additional equipment is required and the equipment is expensive, the shortening of the welding time affects the processing cost.

따라서 현재의 레이저 용착 방식을 개선하여 용착 싸이클 타임을 개선할 필요가 있다.Therefore, there is a need to improve the welding cycle time by improving the current laser welding method.

따라서 본 발명은 상기한 바와 같은 종래의 문제점을 해결하기 위한 것으로, 레이저가 투과되는 제1렌즈 부위에 빔이 집중되도록 볼록부를 설정하고, 제2렌즈가 부가되는 경우 제2렌즈에는 상기 제1렌즈의 볼록부 형상에 대응하는 오목홈을 형성하여 레이저 빔이 집중되는 구조를 가지도록 함으로써 용착 싸이클 타임을 개선하여 가공비를 낮춘 콤비네이션 램프의 레이저 용착 구조를 제공하는 것을 목적으로 한다.Accordingly, the present invention is to solve the above-mentioned problems, and to set the convex portion so that the beam is concentrated on the first lens portion through which the laser is transmitted, and when the second lens is added to the second lens It is an object of the present invention to provide a laser welding structure of a combination lamp in which a concave groove corresponding to the convex shape of the concave portion has a structure in which the laser beam is concentrated to improve the welding cycle time and lower the processing cost.

상기 목적을 달성하기 위해, 본 발명은 콤비네이션 램프에 있어서 하우징에 제1렌즈를 용착하는 레이저 용착 구조로서, 레이저가 투과되는 제1렌즈 부위에 빔이 집중되도록 볼록부가 설정되어 있도록 하여, 하우징의 열전달 시간을 단축하여 용착 싸이클 타임을 줄여줄 수 있다. 이러한 볼록부 형상은 단색 렌즈로 사용되는 경우 제1렌즈 상에 디자인 캐릭터 형상으로도 활용이 가능하여 미관상 매우 유리하다.In order to achieve the above object, the present invention is a laser welding structure for welding the first lens to the housing in the combination lamp, the convex portion is set so that the beam is concentrated on the first lens portion through which the laser is transmitted, heat transfer of the housing The time can be shortened to reduce the welding cycle time. When the convex portion is used as a monochromatic lens, the convex portion may be utilized as a design character shape on the first lens, which is very advantageous in appearance.

또한 상기 제1렌즈 상에 제2렌즈가 배치되는 이색 렌즈 구조에서는, 제2렌즈에 상기 제1렌즈의 볼록부 형상에 대응하는 오목홈을 형성함으로써 실제 외관에는 오목홈이나 볼록부 형상이 노출되지 않도록 할 수 있어 싸이클 타임을 줄여주면서도 미관상 매우 유리하게 할 수 있다.In addition, in the dichroic lens structure in which the second lens is disposed on the first lens, the concave groove corresponding to the convex shape of the first lens is formed in the second lens, so that the concave groove or the convex shape is not exposed to the actual appearance. This reduces the cycle time and can be aesthetically pleasing.

이하 첨부된 도면을 참조하여 본 발명에 따른 콤비네이션 램프의 레이저 용착 구조의 일실시예에 대해 상세히 설명하기로 한다.Hereinafter, an embodiment of a laser welding structure of a combination lamp according to the present invention will be described in detail with reference to the accompanying drawings.

도 2는 본 발명의 일실시예에 따른 콤비네이션 램프의 레이저 용착 구조에 따른 설명도이고, 도 3은 본 발명의 다른 일실시예에 따른 콤비네이션 램프의 레이저 용착 구조에 따른 설명도이다.2 is an explanatory diagram according to the laser welding structure of the combination lamp according to an embodiment of the present invention, Figure 3 is an explanatory diagram according to the laser welding structure of the combination lamp according to another embodiment of the present invention.

도 2는 단색 렌즈의 경우를 설명한 단면도이고 도 3은 이색 렌즈의 경우를 설명한 단면도로서, 도 2의 단색 렌즈 구조는, 하우징(1)에 제1렌즈(2)를 용착할 때, 레이저 빔이 통과하는 제1렌즈(2)의 상면에 볼록부(21)를 형성하여 레이저 빔이 집중되도록 함으로써 열전달이 조속히 이루어져 용융부(11)가 빨리 용융되도록 하는 구조이다. 도 2의 경우 제1렌즈(2) 상에 형성되는 볼록부(21)를 캐릭터 형상으로 함으로써 미관을 향상시킬 수도 있다.FIG. 2 is a cross-sectional view illustrating the case of a monochromatic lens and FIG. 3 is a cross-sectional view illustrating the case of a dichroic lens. The monochromatic lens structure of FIG. 2 has a laser beam when the first lens 2 is welded to the housing 1. The convex portion 21 is formed on the upper surface of the first lens 2 to pass so that the laser beam is concentrated, so that heat transfer is promptly performed and the melting portion 11 is quickly melted. In the case of FIG. 2, the convex portion 21 formed on the first lens 2 may have a character shape, thereby improving aesthetics.

또한 도 3의 이색 렌즈 구조는, 도 2의 단색 렌즈 구조와 동일하나, 이에 부가하여 제1렌즈(2)(예를 들면 적색 렌즈)의 상부에 배치되는 제2렌즈(3)(예를 들면 클리어 또는 앰버 렌즈)에, 제1렌즈(2)의 볼록부(21)와 대응되는 오목홈(31)을 형성함으로써, 레이저 빔의 집중 구조는 그대로 유지하면서도 외관(제2렌즈의 상면)에 오목홈이나 볼록부가 노출되지 않도록 하여 미관을 향상시킬 수 있다.In addition, the dichroic lens structure of FIG. 3 is the same as that of the monochromatic lens structure of FIG. 2, but in addition, the second lens 3 (for example, the red lens) disposed above the first lens 2 (for example, the red lens) is provided. By forming the concave groove 31 corresponding to the convex portion 21 of the first lens 2 in the clear or amber lens, the concave in the appearance (the upper surface of the second lens) while maintaining the concentrated structure of the laser beam Aesthetics can be improved by preventing the grooves or convex portions from being exposed.

이상, 상술한 바와 같이, 본 발명의 콤비네이션 램프의 레이저 용착 구조는 용착 싸이클 타임을 단축시켜 가공비를 줄일 수 있으며, 경우에 따라 볼록부 형상을 캐릭터 디자인으로 활용할 수도 있고, 외관에 아무런 영향도 미치지 않게 할 수 있어 매우 유용하다.As described above, the laser welding structure of the combination lamp of the present invention can reduce the processing cost by shortening the welding cycle time, and in some cases, the convex shape may be used as the character design, so as not to affect the appearance It is very useful to be able to do it.

본 발명은 기재된 실시예에 한정하는 것이 아니고, 본 발명의 사상 및 범위를 벗어나지 않는 한 다양하게 수정 및 변형을 할 수 있음은 당업자에게 자명하다고 할 수 있는 바, 그러한 변형예 또는 수정예들은 본 발명의 특허청구범위에 속하는 것이다.It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit and scope of the invention as defined by the appended claims.
