도어 글래스용 웨더스트립 제조방법{Manufacturing method of wehther strip for door glass}Manufacturing method of wehther strip for door glass

본 발명은 도어 글래스용 웨더스트립 제조방법에 관한 것이다.The present invention relates to a method for manufacturing a weather strip for door glass.

종래의 버스용 폴딩도어의 웨더스트립 조립구조는 폴딩도어 웨더스트립을 일체로 형성하고 이를 폴딩도어에 단순히 끼운구도로 이루어져 있으나, 웨더스트립의 코너부에 주름이 발생되며, 주름을 없애기 위해 코너부 내부에 코어를 형성해야 하기 때문에 웨더스트립의 조립이 어려운 문제점이 있다.The weather strip assembly structure of the conventional folding door for a bus consists of integrally forming the folding door weather strip and simply inserting it into the folding door. Since the core must be formed, there is a problem in that it is difficult to assemble the weather strip.

또한, 웨더스트립과 폴딩도어 간의 단차가 발생하여 수밀성이 떨어지는 문제점이 있다.In addition, there is a problem in that watertightness is deteriorated due to a step difference between the weather strip and the folding door.

본 발명은 상술한 바와 같은 문제점을 해결하기 위한 것으로, 웨더스트립 조립시 코너부의 단차 발생 및 결합력이 저하되어 누수가 발생되는 것을 방지할 수 있는 도어 글래스용 웨더스트립 제조방법을 제공하는 것을 목적으로 한다.An object of the present invention is to provide a method for manufacturing a weather strip for door glass, which can prevent water leakage due to generation of a step difference in corners and a decrease in coupling force when assembling a weather strip. .

상기 목적을 달성하기 위한 본 발명은 도어 글래스용 웨더스트립 제조방법에 관한 것으로, 웨더스트립 단위부재를 압출성형하여 준비하는 단계와, 압출성형된 단위부재를 소정의 길이로 절단하는 단계와, 양단부에 접합면이 형성되고, 소정의 각도로 절곡 형성된 웨더스트립 연결부재를 준비하는 단계 및, 상기 접합면에 상기 단위부재를 접합하는 단계를 포함한다.The present invention for achieving the above object relates to a method for manufacturing a weather strip for door glass, comprising the steps of preparing a weather strip unit member by extrusion molding, cutting the extruded unit member to a predetermined length, and It includes the steps of preparing a weather strip connecting member having a bonding surface formed and bent at a predetermined angle, and bonding the unit member to the bonding surface.

또한, 상기 연결부재는 각각의 일측에 상호 면결합되는 경사접합면을 가지는 한 쌍의 단위 연결부재로 제조되는 단계를 더 포함하는 것이 바람직하다.In addition, it is preferable that the connecting member further comprises the step of manufacturing a pair of unit connecting members having an inclined joint surface that is surface-coupled to each other on one side.

또한, 상기 한 쌍의 단위 연결부재의 각 경사접합면은 면결합된 상태로 열융착 프레스 금형을 통해 접합되는 단계를 더 포함하는 것이 바람직하다.In addition, it is preferable to further include the step of joining each inclined joint surface of the pair of unit connecting members through a heat-sealing press mold in a surface-bonded state.

전술한 구성을 갖는 본 발명의 도어 글래스용 웨더스트립 제조방법은 웨더스트립 조립시 코너부의 단차 발생 및 결합력이 저하되어 누수가 발생되는 것을 방지할 수 있는 효과가 있다.The method for manufacturing a weather strip for door glass according to the present invention having the above-described configuration has an effect of preventing leakage of water due to generation of a step difference in a corner portion and a decrease in bonding force when assembling the weather strip.

도 2는 본 발명의 실시예에 따른 도어 글래스용 웨더스트립 제조방법을 나타낸 정면도이다.1 is a flowchart illustrating a method for manufacturing a weather strip for door glass according to an embodiment of the present invention.
2 is a front view illustrating a method for manufacturing a weather strip for door glass according to an embodiment of the present invention.

이하, 첨부된 도면을 참조하여 본 발명의 실시예에 따른 도어 글래스용 웨더스트립 제조방법을 구체적으로 설명한다.Hereinafter, a method of manufacturing a weather strip for door glass according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

도 1을 참조하면, 실시예에 따른 도어 글래스용 웨더스트립 제조방법은 웨더스트립 단위부재 준비단계(S110), 단위부재 절단단계(S120), 웨더스트립 연결부재 준비단계(S130), 접합단계(S140)로 이루어진다.1 , the method for manufacturing a weather strip for door glass according to the embodiment includes a weather strip unit member preparation step (S110), a unit member cutting step (S120), a weather strip connection member preparation step (S130), and a bonding step (S140). ) is made of

웨더스트립 단위부재 준비단계(S110)는 고무소재가 혼련된 원재료를 일정한 길이를 갖도록 압출 성형하는 것이다.The weather strip unit member preparation step (S110) is to extrude the raw material kneaded with the rubber material to have a certain length.

단위부재(10)의 저면에는 폴딩도어의 프레임에 결합되는 결합부(미도시)가 형성되고, 상면에는 도어 글래스가 결합되는 글래스 결합부(미도시)가 형성된다. A coupling part (not shown) coupled to the frame of the folding door is formed on the bottom surface of the unit member 10 , and a glass coupling part (not shown) coupled to the door glass is formed on the top surface of the unit member 10 .

단위부재 절단단계(S120)는 압출 성형된 단위부재(10)를 원하는 길이를 갖도록 절단하는 것이다.The unit member cutting step (S120) is to cut the extruded unit member 10 to have a desired length.

웨더스트립 연결부재 준비단계(S130)는 양단부에 접합면이 형성되고, 소정의 각도로 절곡 형성된 웨더스트립 연결부재(20)를 준비하는 것이다.The weather strip connecting member preparation step ( S130 ) is to prepare the weather strip connecting member 20 having bonding surfaces formed at both ends and bent at a predetermined angle.

연결부재(20)는 글래스의 모서리부에 결합되는 것으로서, 각각의 일측에 상호 면결합되는 경사접합면(22a)을 가지는 한 쌍의 단위 연결부재(22)를 고무소재가 혼련된 원재료를 일정한 길이를 갖도록 압출 성형되어 제조된다.The connecting member 20 is coupled to the edge of the glass, and a pair of unit connecting members 22 having an inclined joint surface 22a that is surface-coupled to each other on one side is combined with a raw material in which a rubber material is kneaded to a predetermined length. It is manufactured by extrusion molding to have

연결부재(20)의 경사접합면(22a)은 단위 연결부재(20)를 결합시켰을 때 글래스의 모서리를 지지할 수 있도록 소정의 각도가 형성된다.The inclined joining surface 22a of the connecting member 20 is formed at a predetermined angle to support the edge of the glass when the unit connecting member 20 is coupled.

접합단계(S140)는 연결부재(20)의 접합면(22b)에 단위부재(10)를 열융착하여 접합하는 것이다. 이에 따라 종래의 웨더스트립과 같이 웨더스트립을 미가황 상태에서 가접착시킨 후 가황 접착하지 않아도 되기 때문에 생산성이 향상되고, 폴딩도어와 웨더스트립 사이에 단차가 발생되지 않아 수밀성이 형상되는 장점이 있다.In the bonding step (S140), the unit member 10 is heat-sealed to the bonding surface 22b of the connection member 20 and joined. Accordingly, there is an advantage in that productivity is improved because there is no need for vulcanization and adhesion after the weather strip is temporarily bonded in an unvulcanized state like the conventional weather strip, and watertightness is formed because there is no step difference between the folding door and the weather strip.

이상 본 발명의 실시예를 첨부도면을 참조하여 설명하였지만, 당해 기술분야에 숙련된 사람은 하기의 특허청구범위에 기재된 본 발명의 기술적 사상으로부터 벗어나지 않는 범위 내에서 본 발명을 다양하게 수정 및 변경할 수 있음을 이해할 수 있을 것이다.Although the embodiments of the present invention have been described with reference to the accompanying drawings, those skilled in the art can variously modify and change the present invention within the scope without departing from the technical spirit of the present invention described in the claims below.
