Description

열융착장치 {HEAT FUSION APPARATUS}Heat Fusion Equipment {HEAT FUSION APPARATUS}

본 발명은 열융착장치에 관한 것으로, 더욱 상세하게는 열융착시 융착부에 작용되는 응력을 최소화할 수 있는 열융착장치에 관한 것이다.
The present invention relates to a thermal fusion apparatus, and more particularly, to a thermal fusion apparatus that can minimize the stress applied to the fusion unit during thermal fusion.

자동차 부품 중 내장재는 소정형상의 부품을 일부분을 서로 겹친 상태로 접합하여 하나의 부품으로 제작하는 경우가 많은데, 이때 겹쳐진 부분에 열과 압력을 가하여 접합하는 장치를 열융착장치라 한다. The interior materials of automobile parts are often manufactured by joining parts of a predetermined shape in a state where they overlap with each other, and in this case, a device for joining by applying heat and pressure to the overlapped parts is called a heat welding device.

이러한 열융착장치는 지그에 놓인 부품들의 겹쳐진 부분 중 열융착으로 접합되는 지점(이하 융착부라 한다)의 위쪽에서 열융착장치의 열융착툴이 수직으로 왕복 이동하면서 부품의 겹쳐진 부분을 접합하도록 구성된다. The heat welding device is configured to join the overlapping parts of the parts while the heat welding tool of the heat welding device reciprocates vertically above the point where the overlapping parts of the parts placed on the jig are joined by heat welding (hereinafter referred to as a fusion part). .

자동차 내장재 중 도어트림(Door trim)은 부품들을 일부 겹쳐서 열융착작업으로 접합하여 제작하는 대표적인 것으로서, 여기에서 부품은 비닐, 섬유, 직물, 편물, 부직포, 가죽, 합판, 연질목재 압착물, 플라스틱으로 된 판넬 등의 조합으로 이루어진 중첩물로 성형된다. Door trim of automobile interior materials is representative of manufacturing by joining parts by overlapping parts by heat fusion, where parts are made of vinyl, fiber, fabric, knitting, non-woven fabric, leather, plywood, soft wood press, plastic It is molded into an overlap consisting of a combination of panels and the like.

즉, 도어트림에 사용되는 부품은 상기 중첩물 중 몇 가지를 선택하고, 선택된 재료에 접착제를 도포한 후에 서로 겹친 후 압착하여 성형한다. 예를 들면 플라스틱 판넬에 직물, 가죽에 접착제를 도포한 후에 중첩시켜서 도어트림의 부품을 성형하게 된다. That is, the parts used for the door trim are selected from several of the overlaps, and after applying the adhesive to the selected material, they are overlapped with each other and then molded by pressing. For example, a plastic panel is coated with fabric and leather with adhesive and then overlapped to form parts of the door trim.

상기와 같이 성형되는 부품들을 지그에 일부 겹쳐진 상태로 놓고 고정시킨 후에 열융착툴을 하강시켜 접착하고자 하는 부분(융착부)을 가열함과 동시에 가압하여 접합함으로써 도어트림을 성형하게 된다.The parts to be molded as described above are partly overlapped with the jig and fixed, and then the door is molded by pressing and joining the parts to be bonded (fusion parts) by heating and lowering the heat fusion tool.

그러나, 종래의 열융착장치로 도어트림을 성형하면, 부품의 융착부가 지그에 접촉된 상태에서 열융착툴에 의해 가압되므로, 융착부가 지그에 접촉되는 부분에서 열융착툴의 가압에 반발하는 응력이 발생되어 변형되는 문제점이 있었다.However, when the door trim is molded by a conventional heat welding apparatus, the pressure of the heat welding tool against the pressurization of the heat welding tool is reduced because the welding part is pressed by the heat welding tool while the welding part is in contact with the jig. There was a problem that is generated and deformed.

또한, 부품을 구성하는 중첩물은 접착제에 의해 서로 부착되어 있는데, 열융착시 융착부로 가해지는 열과 압력으로 인하여 접착제가 변형되어 중첩물이 서로 떨어져 불량이 발생되는 문제점이 있었다.
In addition, the overlap constituting the parts are attached to each other by the adhesive, there is a problem in that the adhesive is deformed due to the heat and pressure applied to the fusion portion during the heat fusion, the overlap is falling off each other a failure occurs.

본 발명은 상기와 같은 문제점을 해결하기 위하여 안출한 것으로, 열융착툴에 의해 열융착되는 부품의 융착부가 지그에 접촉되는 것을 최소화하여, 융착부가 열과 응력에 의해 변형되는 것을 방지할 수 있는 열융착장치를 제공하는데 그 목적이 있다.The present invention has been made in order to solve the above problems, by minimizing the contact of the fusion portion of the parts heat-sealed by the heat welding tool to the jig, heat fusion can be prevented from deforming by the heat and stress The purpose is to provide a device.

그러면, 지그(20)에 놓인 부품(10)(11)중 융착돌부(10a)가 열융착핀(31)에 의해 용융됨고 동시에 눌려져서 끼움구멍(11a)의 주변에 압착된 상태로 접합됨으로 서로 다른 두 개의 부품(10)(11)이 하나의 부품으로 성형된다. Then, the fusion protrusions 10a of the parts 10 and 11 placed on the jig 20 are melted by the heat fusion pins 31 and simultaneously pressed and joined to each other in a state of being pressed into the periphery of the fitting hole 11a. The other two parts 10, 11 are molded into one part.

또한, 냉각부(50)가 구비되는 경우에는 열융착작업을 수행하면 동시에 냉각부(50)도 작동되어 열융착툴(30)이 융착부(15)를 가압 가열할 때, 에어공급부(51)는 에어를 발생시켜 융착부(15)로 에어를 공급하여 냉각시키는 작업을 수행한다. In addition, when the cooling unit 50 is provided, the cooling unit 50 is operated at the same time as the heat welding operation is performed, and the air supply unit 51 when the heat welding tool 30 pressurizes and heats the welding unit 15. Generates air to supply air to the fusion unit 15 to perform cooling.
