본 고안은 합성수지제의 특히 대형인 계기커버 등의 초음파 용착에 있어서 적용 가능한 다이렉터 구조에 관한 것이다.The present invention relates to a director structure applicable to ultrasonic welding of a synthetic cover made of a particularly large instrument cover.
대형인 합성수지제의 계기커버 등을 전주위에 걸처 균일하게 초음파 용착하는 것은 용착기의 능력 등의 면에서 곤란한 것이다.Ultrasonic welding of a large synthetic resin instrument cover or the like over the entire periphery is difficult in terms of the capacity of the welding machine.
제4도는 그의 일예로서 차량용의 운행 기록계를 도시한 것이고 합성수지제의 전면커버(6)의 뒤측에는 투명수지커버(5)가 용착되어 있다.4 shows a driving recorder for a vehicle as an example thereof, and a transparent resin cover 5 is welded to the rear side of the front cover 6 made of synthetic resin.
제5도는 그 커버(5, 6)의 용착전의 상태를 도시한 것이다.5 shows a state before welding of the covers 5 and 6.
즉, 전면커버(6)의 이연(7)에 단면 3각 형상의 복수의 폴상 다이렉터(집중발열체)(8...)를 거의 등간격으로 분산하여 형성하고 있고 투명커버(5)를 이 다이렉터(8)에 밀착시켜 도시하지 않은 초음파 용착기에 의해 이 다이렉터(8)를 용융시킴으로써 양커버(5, 6)를 용착하는 것이다.That is, a plurality of pole-shaped directors (central heating elements) 8 ... having a triangular cross-sectional shape are formed on the edge 7 of the front cover 6 at substantially equal intervals, and the transparent cover 5 is formed in this manner. Both covers 5 and 6 are welded by bringing the director 8 into close contact with the director 8 and melting the director 8 with an ultrasonic welding machine (not shown).
그러나 상기 종래의 다이렉터 구조에 있어서는 제6도에 도시한 바와같이 용착 후에 인접하는 마이렉터(8, 8)의 사이에 틈(9)이 생기기 때문에 그의 틈(9)에서 계기 내에 먼저나 수분이 침입하여 버리는 문제가 있었다.However, in the conventional director structure, as shown in FIG. 6, a gap 9 is formed between the adjacent directors 8 and 8 after welding, so that moisture is first introduced into the meter at the gap 9 thereof. There was a problem of invading.
특히 수분이 침입했을 경우에는 투명커버(5)의 내면이 흐려저 계기(속도표시등)가 보기 힘들어 진다고하는 결정이 있었다.In particular, when moisture invaded, it was determined that the inner surface of the transparent cover 5 was blurred, making the instrument (speed indicator) difficult to see.
본 고안은 상기한 점에 감안하여 계기 등으로의 먼지나 수분의 침입을 방지 가능한 초음파 용착의 다이렉터 구조를 제공하는 것을 목적으로 한다.In view of the above, an object of the present invention is to provide a director structure for ultrasonic welding capable of preventing intrusion of dust or moisture into an instrument or the like.
상기 목적을 달성하기 위해 본 고안은 합성수지체의 용착면에 대하여 주다이렉터를 돌출설치 함과 동시에 주다이렉터 보다도 체적이 작은 부다이렉더를 이 주다이렉터에 연계하여 일체로 힝성하여 이루어지는 구조를 채용한다.In order to achieve the above object, the present invention adopts a structure in which the main director is projected on the welded surface of the synthetic resin body and at the same time, the subdirector having a smaller volume than the main director is connected to the main director and integrally formed.
초음파 용착에 있어, 우선 주다이렉더가 용융하고 이어서 부다이렉터(의 선단부)가 용융한다. 따라서 주다이렉터에 의해 용착 강도를 유지하고 부다이렉터에 의해 인접하는 주다이렉터 사이의 틈을 밀폐할수가 있다. 제1도는 본 고안에 관한 초음파 용착의 다이렉터 구조의 일실시예를 도시한 것이다.In ultrasonic welding, the main director melts first, followed by the subdirector. Therefore, the welding strength can be maintained by the main director and the gap between adjacent main directors can be closed by the subdirector. 1 shows an embodiment of the director structure of ultrasonic welding according to the present invention.
즉, 이 다이렉터(집중발열체)구조는 상술한 운행 기록계에 있어서의 합성수지제의 전면커버(1)의 이연(용착면)(2)에 단면3각형상의 복수의 주다이렉터(3...)를 거의 등간격으로 돌출하여 형성함과 동시에 상호 인접하는 주다이렉터(3, 3)사이에 이 주다이렉터(3)를 연계하는 부다이렉터(4)를 일체로 형성하여 이루어지는 것이다.That is, this director (concentrated heating element) structure has a plurality of main directors (3) in the shape of a triangular cross section on the deferred (welding surface) 2 of the front cover 1 made of synthetic resin in the above-described driving recorder. Is formed by protruding substantially at equal intervals, and at the same time, the subdirectors 4 which connect the main directors 3 are integrally formed between the main directors 3 and 3 adjacent to each other.
여기서 부다이렉터(4)는 제2도에 제1도의 A부 혹대도를 도시한 바와같이 주다이렉터(3)에 대하여 축적한 상사 형상으로 형성하고있다.Here, the sub-director 4 is formed in a similar shape accumulated with respect to the main director 3, as shown in FIG.
제3도(a)는 그의 다이렉터 구조의 평면도, (b)는 (a)의 B-B단면을 도시한 것이고 다이렉터(3, 4)에 대향하여 투명커버(5)를 세트하고, 도시하지 않은 초음파 용착기에 의해 상호 가압 밀착하여 초음파를 발진하면 제3도(c)에 도시한 바와같이, 즉 다이렉터(3)의 태반은 용융하여 용착하고, 또한 부다이렉터(4)는 그의 선단부(4a)를 용융하여(제3도(b)의 h선까지 용융한다)인접하는 주다이렉터(3, 3)의 사이에 틈 없이 용착한다.FIG. 3 (a) is a plan view of the director structure thereof, (b) shows the BB cross section of (a), and the transparent cover 5 is set opposite to the directors 3 and 4, and is not shown. When the ultrasonic waves are oscillated by mutual pressure contact with an ultrasonic welding machine, as shown in FIG. 3 (c), that is, the placenta of the director 3 is melted and welded, and the subdirector 4 has its front end portion 4a. Is melted (melted to line h in Fig. 3 (b)) and welded without any gap between the main directors 3 and 3 adjacent to each other.
따라서 전면커버(1)와 투명커버(5)의 사이에는 틈이 전혀 없어지고 계기 내로의 먼지나 수분의 침입을 방지할 수가 있다. 또 초음파 용착기는 부다이렉터의 체적이 작기 때문에 종래와 동일 능력의 것도 사용 가능하다.Therefore, there is no gap between the front cover 1 and the transparent cover 5, and it is possible to prevent intrusion of dust or moisture into the instrument. Moreover, since the volume of a subdirector is small, an ultrasonic welding machine can also use the thing of the same ability as before.
이상과 같이 본 고안은 합성지의 용착 면에 대하여 주다이렉터를 돌출설치 함과동시에 이 주다이렉터 보다도 체적이 작은 부다이렉터를 이 주다이렉터에 연계하여 일체로 형성하여 이루어지는 구조를 채용했기 때문에 초음파 용착에 의해 주다이렉터가 용융함과 동시에 부다이렉터가 용융하고 이 부다이렉터에 의해 인접하는 주다이렉터 사이의 틈을 밀폐할 수가 있다.As described above, the present invention adopts a structure in which the main director is projected on the welding surface of the synthetic paper and a sub-director having a smaller volume than that of the main director is integrally formed in conjunction with the main director. As the main director melts, the subdirector melts, and the subdirector can seal the gap between adjacent main directors.
따라서 계기내 등에 먼지나 수분이 침입하는 일이 없고, 계기등이 수명이 연장됨과 동시에 수분의 침입에 수반되는 계기의 투명커버의 흐림을 방지할 수가 있다.Therefore, dust and water do not invade the inside of the instrument, and the life of the instrument can be extended, and at the same time, the transparent cover of the instrument accompanying the ingress of moisture can be prevented.
