즉, 도 10 내지 도 14에 도시되어 있는 스태킹 용접공정도와 같이 먼저 도어트림(100)의 일면에 돌출된 돌기(110)와 도어트림씰(200)의 조립공(210)을 일치시키고(도 10 참조), 상기한 도어트림(100)의 돌기(110)에 조립공(210)이 끼워지게 도어트림씰(200)을 조립한다.(도 11 참조)That is, as shown in the stacking welding process illustrated in FIGS. 10 to 14, the protrusion 110 projecting on one surface of the door trim 100 coincides with the assembly hole 210 of the door trim seal 200 (see FIG. 10). ), The door trim seal 200 is assembled so that the assembly hole 210 is fitted into the protrusion 110 of the door trim 100. (See FIG. 11)

이어서, 상기한 도어트림씰(200)이 조립되어 있는 도어트림(100)을 히팅금형(300)의 하부로 이송시켜서 조립공(210)을 통해 상방으로 돌출된 돌기(110)의 돌출단을 상기 히팅금형(300)의 하단에 형성된 용접홈(310) 하부에 일치시키고(도 12 참조), 상기 히팅금형(300)을 하강작동시키키게 되면 돌기(110)의 돌출단이 용접홈(310)에 삽입됨과 동시에 용융되어 넓게 퍼지게 되며(도 13 참조), 이와 같이 돌기(110)의 돌출단이 상기 히팅금형(300)의 용접홈(310)에 내부에서 용융되면서 넓게 퍼진 상태가 되면 히팅금형(300)을 상승작동시키게 되면 스태킹용접작동이 완료되는데, 이때 종래 기술의 히팅금형(300)은 항시 플라스틱을 순간적으로 용융시킬 수 있는 고열을 유지하고 있는 상태이기 때문에 돌기(110)의 돌출단을 눌러주면서 용융시켜서 넓게 퍼뜨리는 순간에도 고열을 유지하고 있게 된다. 따라서 상기 히팅금형(300)의 용접홈(310)에 의해 눌림되면서 용융되어 넓게 퍼지게 되는 용융결속부(120)는 히팅금형(300)에 의해 용융될 때의 고온을 유지하고 있기 때문에 상기 히팅금형(300)을 상승시킬 때 용접홈(310)의 내면에서 쉽게 이완되지 못하고 상기한 용융결속부(120)의 일부가 상기한 용접홈(310) 내면에 달라붙은 상태가 되는 문제가 발생되므로 용융결속부(120)의 외면이 울퉁불퉁해지는 단점이 있다.(도 14 참조)Subsequently, the door trim 100 in which the door trim seal 200 is assembled is transferred to the lower portion of the heating mold 300 to heat the protruding end of the protrusion 110 protruding upward through the assembly hole 210. Match the lower portion of the welding groove 310 formed at the bottom of the mold 300 (see FIG. 12), and when the heating mold 300 is lowered and operated, the protruding end of the protrusion 110 is inserted into the welding groove 310. At the same time it is melted and spread widely (see FIG. 13), and thus, when the protruding end of the protrusion 110 is melted in the welding groove 310 of the heating mold 300 and spreads widely therein, the heating mold 300 When the rising operation is completed, the stacking welding operation is completed, the heating mold 300 of the prior art is melted while pressing the protruding end of the protrusion 110 because the state of maintaining a high temperature to melt the plastic at any moment High fever even at the moment I keep it. Therefore, the melt bonding part 120, which is pressed by the welding groove 310 of the heating mold 300 and melted and spreads widely, maintains a high temperature when it is melted by the heating mold 300 and thus the heating mold ( When the 300 is raised, a problem arises that a part of the melt binding unit 120 is stuck to the inner surface of the welding groove 310 because it is not easily relaxed on the inner surface of the welding groove 310, and thus the melt binding unit There is a disadvantage that the outer surface of the 120 is bumpy (see Fig. 14).

또한 도 14의 도시와 같이 히팅금형(300)이 상승될 때 용접홈(310)의 내면에 달라붙은 플라스틱 찌꺼기(130)는 계속된 히팅금형(300)의 가열작동에 의해 완전히 연소되어 재(탄소)로 변하게 되며, 상기한 재(탄소)는 다음의 스태킹용접공정시 용융결속부(120)의 표면에 붙게되는 문제를 발생시키게 되어 도어트림(100) 제품의 불량률을 높아지게 된다.In addition, as shown in FIG. 14, when the heating mold 300 is raised, the plastic residue 130 stuck to the inner surface of the welding groove 310 is completely burned by the heating operation of the heating mold 300 to be ashed (carbon ), The ash (carbon) will cause a problem that is attached to the surface of the melt binding unit 120 during the next stacking welding process to increase the defective rate of the door trim (100) product.

또한 상기한 히팅금형(300)은 항상 고열로 가열되어 있어 전기소모가 크며, 용접기계의 재조정시 고열에 의해 제한을 받아 재조정이 어렵기 때문에 항상 플라스틱이 타는 냄새가 발생된다.In addition, the heating mold 300 is always heated to a high temperature, so that the electrical consumption is large, because it is difficult to readjust because it is limited by the high temperature when the readjustment of the welding machine is always a burning smell is generated.

따라서 상기와 같은 문제를 해결하기 위해 히팅금형(300)을 하강시켜서 용접작동을 한 후 상승작동시킨 다음에는 용접홈(310)에 달라붙어 있는 플라스틱 찌꺼기(130)를 제거하기 위해 에어브러쉬를 작동시키는 동안에는 스태킹용접작업을 할 수 없게 되어 도어트림(100)에 드러트림씰(200)을 결합시키는 스태킹용접작업성이 떨어지는 문제가 발생하게 된다.Therefore, in order to solve the above problems, the heating mold 300 is lowered and then operated to raise and then operate the airbrush to remove the plastic residue 130 stuck to the welding groove 310. During the stacking welding operation is not possible, there is a problem that the stacking welding workability of coupling the drum trim seal 200 to the door trim 100 occurs.

한편, 상기와 같은 히팅금형(300)에서 나타나는 문제을 해결하기 위하여 상기 도어트림(100)과 도어트림씰(200)을 초음파 진동을 이용하여 용접시키는 방법이 제안된 바 있었으나, 이는 초음파 진동장치가 고가이고 또 초음파 진동을 이용하여 용접하는데 많은 비용이 소요되므로 용접가공비가 비싸지게 되어 중저가의 플라스틱 제품을 초음파 진동으로 용접하는 데에는 경제적인 부담이 뒤따르게 된다는 것이 문제점으로 지적되고 있다.
On the other hand, in order to solve the problem appearing in the heating mold 300 as described above has been proposed a method of welding the door trim 100 and the door trim seal 200 using ultrasonic vibration, which is expensive ultrasonic vibration device In addition, it is pointed out as a problem that it is expensive to weld by using ultrasonic vibration, so that the welding processing cost becomes expensive, resulting in an economic burden for welding a low-cost plastic product by ultrasonic vibration.

(3) is relaxed in a smooth state even when it is relaxed in the ceramic coating layer 33 of the welding groove 32 by the rising operation.

상기와 같이 스태킹용접장치(3)가 하강 및 상승작동으로 하나의 돌기(11)의 돌출단을 용융시켜서 용융결속부(12)를 형성시키는 한차례의 용접작동이 완료되면 스태킹용접시스템의 이동제어장치는 자동으로 플라스틱 제품(1)을 이동시켜서 다음의 돌기(11)가 스태킹용접장치(3)의 직하방에 위치하도록 고정시키게 되며, 이어서 상기 스태킹용접장치(3)는 앞에서 설명한 스태킹용접작동의 가공공정순서를 반복해서 작동하여 돌기(11)의 돌출단을 차례대로 용융시켜 용접하게 되는 것이다.As described above, when the stacking welding device 3 completes one welding operation of melting the protruding end of one projection 11 by the lowering and raising operation to form the molten binder 12, the movement control device of the stacking welding system. Automatically moves the plastic product 1 so that the next protrusion 11 is positioned directly below the stacking welding device 3, and the stacking welding device 3 then processes the stacking welding operation described above. The process sequence is operated repeatedly to melt and weld the protruding end of the protrusion 11 in order.
