또한 본 발명의 버핑수단(12)은 와인딩 롤(2)을 교환할 경우에도 마찬가지로, 먼저 가공기(10) 전에 있는 동력원(20)을 구동시켜 프레임(18)을 하강시키므로 승강 롤러(16)가 도시한 점선과 같이 아래쪽으로 최대한 하강되게 하고, 그 상태에서 공정의 진행 속도에 맞추어 승강 롤러(16)를 서서히 상승시켜 전극 기재(6)의 선단(도면의 우측 끝단)이 움직이지 않게 하며, 그때를 이용하여 와인딩 롤(4)을 제거 및 교환할 수 있다.In addition, when the buffing means 12 of the present invention replaces the winding rolls 2, the lifting roller 16 is shown because the first driving the power source 20 before the processing machine 10 lowers the frame 18. As shown in the dotted line, it is lowered downward as much as possible, and in that state, the lifting roller 16 is gradually raised in accordance with the progress speed of the process so that the tip (right end of the drawing) of the electrode substrate 6 is not moved. Can be used to remove and replace the winding roll 4.
이상에서 설명한 구성 및 작용을 통하여 알 수 있는 바와 같이, 본 발명에 의한 이차전지의 전극 제조장치는 버핑수단을 부가하여 종래 기술의 문제점을 실질적으로 해소하고 있다.As can be seen through the configuration and operation described above, the electrode manufacturing apparatus of the secondary battery according to the present invention substantially solves the problems of the prior art by adding a buffing means.
즉 본 발명에 의하면 언와인딩 롤 및 와인딩 롤을 교환시에도, 제조 공정을 중단하지 않고 연속적으로 공정을 수행할 수 있으며, 그에 따라 교환 작업에 따른 시간 손실을 제거할 수 있다.That is, according to the present invention, even when the unwinding roll and the winding roll are replaced, the process can be continuously performed without interrupting the manufacturing process, thereby eliminating time loss due to the replacement operation.
또한 본 발명에 의하면 공정을 중단하지 않으므로 전극 기재가 공정 중에 잔류되지 않으며, 그에 따라 재료 손실을 방지할 수 있다.In addition, according to the present invention, since the process is not interrupted, the electrode substrate does not remain during the process, and thus material loss can be prevented.
