Abstract

본 발명은 리튬이온전지의 제조공정에서 반제품으로서의 제조공정완료 후 펠릿에 적재하기전에 송출컨베어상에서 쓰러진 전지를 감지하여 이를 배출하도록 된 리튬이온전지의 쓰러짐감지 및 배출장치에 관한 것으로, 컨베이어(C)에서 이송중인 리튬이온전지(B)중 제1감지센서(1)의 광신호발신시 정상이송중인 리튬이온전지(B)와 쓰러진 리튬이온전지(B')의 길이폭에 따른 파형으로 차등감지신호를 송출하고 타이머(2)는 이를 시간(초단위)으로 환산하고 컨트롤러(3)는 제1감지센서(1)의 차등감지신호를 환산한 시간에 따라 실린더(4)를 작동시켜 푸셔(5)가 컨베이어(C)상의 쓰러진 리튬이온전지(B')를 밀어주어 배출로(6)를 통해 배출되게 하여 타전지와의 접촉을 방지하므로써, 접촉시 전류방전에 따른 전지내부의 이상가열과 전해액의 화학반응으로 인한 발화나 전지폭박을 미연에 예방할 수 있으며, 불량품을 미리 제거하여 완제품출하시 불량품이 섞여 출화됨을 방지할 수 있어 고성능전지로서의 제품이미지와 신뢰도를 향상시키는 효과를 제공하는 것이다.The present invention relates to a fall detection and discharge device of a lithium ion battery, which detects a discharged battery on a delivery conveyor and discharges it before loading into a pellet after completion of a manufacturing process as a semi-finished product in a manufacturing process of a lithium ion battery. The differential detection signal is a waveform according to the length width of the lithium ion battery (B) and the collapsed lithium ion battery (B ') during normal transmission when the optical signal of the first detection sensor (1) among the lithium ion batteries (B) being transferred from And the timer 2 converts it to time (seconds) and the controller 3 operates the cylinder 4 according to the time converted from the differential detection signal of the first detection sensor 1 to push the pusher 5. The secondary lithium ion battery (B ') on the conveyor (C) is pushed out through the discharge path (6) to prevent contact with other batteries, thereby causing abnormal heating and electrolyte Foot caused by chemical reaction It is possible to prevent fire or battery explosion in advance, and to prevent defective products from being mixed with fire by removing the defective products in advance, thus providing an effect of improving product image and reliability as a high performance battery.
