Abstract

본 발명은 리튬 1차전지의 와인딩어세이 제조시 리튬포일의 슬립에러에 따른 캐소드와의 길이차를 방지하도록 임의의 길이로 기 공급된 캐소드(22)를 동기검출기(110)(111)와 수신기(120)(121)가 각기 설치위치에서 측정한 캐소드(22)의 길이값 a1, b1에 라인센서(130)가 측정한 최종 길이값 x1을 출력하여 이 출력신호에 따라 컨트롤러(140)가 보빈(30)에서 피딩룰러(170)를 거쳐 피딩되는 리튬포일(21)의 길이값 (a+b+x)1을 센서(150)가 감지하여 컨트롤러(140)의 지령신호를 받는 커터(160)가 측정길이만큼 커팅하므로 정밀한 작업에 다른 생산성향상 및 리튬포일과 캐소드간의 절연성의 향상에 따른 리튬포일과 캐소드간의 단락이나 전해액과의 산화작용이 발생됨을 방지하여 전지의 폭발까지도 예방하는 효과를 갖는 것이다.The present invention provides a cathode 22, which is supplied with a predetermined length, to prevent a difference in length with a cathode due to a slip error of a lithium foil in the manufacture of a winding assay of a lithium primary battery, the synchronous detectors 110 and 111 and a receiver. The controller 140 outputs the final length value x1 measured by the line sensor 130 to the length values a1 and b1 of the cathodes 22 measured at the installation positions by the 120 and 121 respectively. The cutter 160 detects the length value (a + b + x) 1 of the lithium foil 21 fed through the feeding ruler 170 at 30 and receives a command signal from the controller 140. Since cutting is as much as the measuring length, it prevents the explosion of battery by preventing short circuit between lithium foil and cathode or oxidation action of electrolyte due to other productivity improvement and insulation between lithium foil and cathode in precision work. .
