Abstract

The present invention relates to a method for producing a car lamp using vibration fusion. The method comprises the steps of: (S10) positioning a housing and a lens in a mold; (S20) fixing the parts positioned in the mold; (S30) moving a heater toward the housing and lens; (S40) preheating the housing and lens through the moved heater; (S50) causing the heater to return to the original position; (S60) carrying out vibration fusion of the preheated housing and lens; and (S70) removing the parts coupled to each other in the step (S60) from the mold. The method for producing a car lamp using vibration fusion according to the present invention softens the binding portion of the housing and lens through preheating to a predetermined temperature, and thus inhibits generation of burrs during the vibration fusion.

Description

진동융착을 통한 자동차 램프의 제조방법{Product process for vehicle lamp using vibration welding}BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a vehicle lamp,

본 발명은 진동융착을 통한 자동차 램프의 제조방법에 관한 것이다.
The present invention relates to a method of manufacturing an automobile lamp through vibration welding.

일반적으로 열가소성 수지로 된 두 개의 부재를 접합하는 방식으로, 접합하고자 하는 상,하부 부재 중 어느 한 부재에 접착제를 바르거나 초음파융착 또는 진동융착방식을 통해 접합하는 방식이 있다.Generally, there is a method of bonding two members made of a thermoplastic resin by applying an adhesive to one of the upper and lower members to be bonded, or bonding them by ultrasonic welding or vibration welding.

그러나 이러한 방식은 접착제의 사용에 따라 환경오염이 발생되고, 접합부분이 매끄럽지 않으며, 또한 접합강도가 일정하지 않아 기계적 외력이 가해졌을 때 제품 내부의 손상이 발생되었으며 무엇보다 수밀성의 문제가 발생되었다.However, this method causes environmental pollution due to the use of the adhesive, does not smooth the joint part, and the bonding strength is not constant, so that when the mechanical external force is applied, the inside of the product is damaged, and water tightness problems occur.

이러한 문제점에 의거하여, 국부적으로 열을 전도함과 동시에 비접촉식으로 구현하는 레이저 융착방식이 제안되었다.Based on these problems, a laser welding method has been proposed in which local heat conduction and simultaneous non-contact implementation are realized.

레이저 융착방식이란, 융착 대상물인 상부부재와 하부부재를 밀착시킨 상태에서, 밀착된 부재의 테두리 부분 혹은 그 일부를 레이저를 이용하여 융착하는 것으로서, 상부부재는 레이저빔이 투과되는 재질이 사용되고 하부 부재는 레이저빔이 흡수되는 재질을 사용한다.The laser welding method is a method of fusing an edge portion or a part of an adhered member in a state in which an upper member and a lower member which are objects to be fused are in close contact with each other by using a laser. The upper member is made of a material through which a laser beam is transmitted, A material which absorbs the laser beam is used.

그런데 레이저 융착이 가능하기 위하여, 상부부재와 하부부재는 동종 재질로 되어야 한다. 만약 이종 재질의 부재를 레이저를 이용하여 융착하고자 할 경우, 재질에 따른 온도특성이 달라 융착이 완전히 이루어지지 않게 되었다. 즉 일반적인 레이저 융착방식으로는, 이종 재질로 된 자동차램프, 즉 PC 및 PMMA 재질로 된 투과성 커버와, 자동차 본체에 고정되는 것으로서 PP, PET 또는 ABS 재질로 비투과성 하우징을 상호 융착하기가 현실적으로 가능하지 않았다라는 문제점이 있었다.
However, in order to enable laser welding, the upper member and the lower member must be made of the same material. If a different kind of material is to be fused by using a laser, the temperature characteristic depending on the material is different, and fusion is not completely performed. That is, in the general laser welding method, it is practically possible to mutually fuse an automotive lamp made of different materials, that is, a transparent cover made of PC and PMMA, and a non-transparent housing made of PP, PET or ABS, There was a problem.

상기 S40 단계에서 상기 히터는 진동융착되는 상기 하우징 및 렌즈의 접합부를 예열시키도록 제어될 수 있다. In step S40, the heater may be controlled to preheat the junction of the housing and the lens to which the vibration is adhered.

상기 하우징 및 렌즈의 접합부는 예열에 의해 연화될 수 있다. The joints of the housing and the lens can be softened by preheating.

Fig.

도면을 참조하면 본 실시예에 따른 진동융착을 통한 자동차 램프의 제조방법은 부품(하우징(10) 및 렌즈(20))를 금형에 안착시키는 단계(S10)와, 상기 금형에 안착된 부품을 고정시키는 단계(S20)와, 히터(30)를 이동시키는 단계(S30)와, 상기 이동된 히터(30)를 통해 부품을 예열시키는 단계(S40)와, 상기 히터(30)를 원위치로 복귀시키는 단계(S50)와, 예열된 상기 하우징(10) 및 렌즈(20)를 진동융착시키는 단계(S60)와, 상기 S60 단계에서 결합된 부품을 금형에서 취출시키는 단계(S70)를 포함한다. Referring to the drawings, a method of manufacturing an automobile lamp using vibration welding according to the present embodiment includes the steps of (S10) placing a component (housing 10 and lens 20) on a mold, A step S30 of moving the heater 30, a step S40 of preheating the part through the moved heater 30, a step of returning the heater 30 to the home position, A step S60 of vibration welding the preheated housing 10 and the lens 20, and a step S70 of taking out the combined parts from the mold in the step S60.

상기 S10 단계는 금형에 부품을 안착시키는 단계로서, 본 실시예에서는 자동차 램프의 하우징(10) 및 렌즈(20)를 안착시킨다. In the step S10, the parts are seated on the mold. In this embodiment, the housing 10 and the lens 20 of the automobile lamp are seated.

상기 S20 단계는 금형에 상기 하우징(10) 및 렌즈(20)를 고정시키는 단계로서, 본 실시예에서는 금형에 설치된 지그를 이용해 상기 하우징(10) 및 렌즈(20)를 고정시킨다. In the step S20, the housing 10 and the lens 20 are fixed to the mold. In this embodiment, the housing 10 and the lens 20 are fixed using a jig provided on the mold.

상기 부품을 고정시키는 방법 및 구조는 당업자에 의해 다양한 방법으로 실시될 수 있다. The method and structure for securing the part can be carried out by a person skilled in the art in various ways.

상기 S30 단계는 융착고정을 위해 히터(30)를 부품 측으로 이동시키는 단계로서, 본 실시예에서 상기 히터(30)는 IR 히터가 사용된다. The step S30 is a step of moving the heater 30 to the component side for fusion fixing. In this embodiment, the heater 30 is an IR heater.

본 실시예에서 상기 히터(30)는 상기 하우징(10) 및 렌즈(20)의 접합부(15)(25)를 각각 예열시킨다.In the present embodiment, the heater 30 preheats the joining portions 15 and 25 of the housing 10 and the lens 20, respectively.

상기 S40 단계는 상기 히터(30)에서 발생된 열을 이용하여 상기 하우징(10) 및 렌즈(20)의 접합부(15)(25)를 예열시키는 단계로서, 상기 하우징(10)은 110도 내지 140도 까지 접합부(15)를 예열시키고, 렌즈(20)는 120도 내지 160도까지 접합부(25)를 예열시킨다. The step S40 is a step of preheating the joining portions 15 and 25 of the housing 10 and the lens 20 using the heat generated from the heater 30, And the lens 20 preheats the joint 25 to 120 to 160 degrees.

상기 S50 단계는 상기 접합부(15)(25)의 예열 후에 상기 히터(30)를 원위치로 복귀시키는 단계이다. The step S50 is a step of returning the heater 30 to the home position after the preheating of the bonding portions 15 and 25. [

상기 S60 단계는 접합부(15)(25)가 예열된 상기 하우징(10) 및 렌즈(20)를 진동융착을 통해 접합시키는 단계이다. The step S60 is a step of bonding the housing 10 and the lens 20 preheated by the bonding portions 15 and 25 to each other through vibration welding.

도 3에 도시된 바와 같이, 부품의 어느 한 쪽만을 예열하여 진동융착을 실시하는 경우, 연화된 재료가 성형과정에서 버(11)를 발생시키게 된다. As shown in FIG. 3, when only one of the components is preheated and subjected to vibration welding, the softened material generates burrs 11 in the molding process.

그러나 도 2에 도시된 바와 같이, 진동융착되는 각 부품의 접합부(15)(25)를 예열시켜 재료를 연화시키는 경우, 진동융착을 실시하여도 버가 발생되는 것을 방지할 수 있다. However, as shown in Fig. 2, in the case of softening the material by preheating the joining portions 15 and 25 of the respective parts to be vibration-welded, it is possible to prevent occurrence of burrs by performing vibration welding.

특히 본 실시예에서는 렌즈(20)의 접합부(25)가 예열되어 재료가 연화되고, 진동융착 시 렌즈(20) 재질이 하우징(10) 버가 발생되는 것을 눌러주는 역할을 담당한다. Particularly, in this embodiment, the joining portion 25 of the lens 20 is preheated to soften the material, and when the vibration welding is performed, the material of the lens 20 plays a role of pressing the burr of the housing 10.

상기 진동융착 성형방법은 당업자에게 일반적인 기술내용이기 때문에 상세한 설명을 생략한다. Since the vibration welding and forming method is a general description to those skilled in the art, a detailed description thereof will be omitted.

상기 S70 단계는 진동융착을 통해 접합된 램프를 금형에서 취출하는 단계이다. The step S70 is a step of taking out the laminated lamp from the mold through vibration welding.

이와 같이, 본 실시예에서는 별도의 구조물 없이 버 발생을 방지할 수 있고, 이를 통해 버가 발생된 램프에 비해 발광효율이 높은 효과가 있다. As described above, according to the present embodiment, it is possible to prevent the occurrence of burrs without a separate structure, and it is effective to have a higher luminous efficiency than a lamp in which burrs are generated.

더불어 상기 접합부(15)(25)가 예열되어 연화되기 때문에, 진동융착 시 접합시간이 단축되고, 접합된 강도 역시 상승되는 효과가 있다. In addition, since the bonding portions 15 and 25 are preheated and softened, there is an effect that the bonding time is shortened during vibration welding and the bonded strength is also increased.

이상 첨부된 도면을 참조하여 본 발명의 실시예들을 설명하였으나, 본 발명은 상기 실시예들에 한정되는 것이 아니라 서로 다른 다양한 형태로 제조될 수 있으며, 본 발명이 속하는 기술분야에서 통상의 지식을 가진 자는 본 발명의 기술적 사상이나 필수적인 특징을 변경하지 않고서 다른 구체적인 형태로 실시될 수 있다는 것을 이해할 수 있을 것이다. 그러므로 이상에서 기술한 실시예들은 모든 면에서 예시적인 것이며 한정적이 아닌 것으로 이해해야만 한다.
