(not shown) is included.

그리고, 상기 화재감지센서에 의해 화재발생이 인지되면, 제어부는 상기 커버(371)를 덮어 화재 확산을 억제하는 동시에 시스템 내 작동중인 기기의 운행정지를 지시한다.In addition, when the occurrence of a fire is recognized by the fire detection sensor, the control unit covers the cover 371 to suppress the spread of fire and at the same time instructs the operation of devices operating in the system to be stopped.

셀취출부(40)는 배터리셀의 취출작업을 수행하는 구성으로서, 취출로봇(41), 상기 취출로봇(41)에 인접 배치되는 배터리셀 반출용 제2이송대차(43)와 트레이 반출용 제3이송대차(45)로 이루어지며, 상기 제2이송대차(43)와 제3이송대차(45)는 모두 이송레일(11) 직하에 배치된다. The cell take-out unit 40 is a component that performs a take-out operation of the battery cells, and includes a take-out robot 41, a second transfer cart 43 for taking out the battery cells disposed adjacent to the take-out robot 41, and a tray take-out tray. It consists of three transfer carts 45, and both the second transfer cart 43 and the third transfer cart 45 are disposed directly below the transfer rail 11.

배터리분해부(30)에서 분해작업이 완료되면, 절취된 스크랩은 제1이송대차(35)에 하적되고, 트레이 상에는 셀 단위까지 분해된 폐리튬이온배터리팩(A)이 남게 되며, 이러한 트레이를 상기 갠트리 로봇(13)이 파지하여 먼저 제2이송대차(43) 직상부로 이송한 다음, 트레이를 뒤집어 배터리셀을 덤핑한 후 해당 트레이를 제3이송대차(45)에 하적한다.When the disassembly operation is completed in the battery disassembly unit 30, the cut scraps are loaded onto the first transfer cart 35, and the waste lithium ion battery pack A disassembled to the cell unit remains on the tray. The gantry robot 13 grips and first transfers the battery directly above the second transfer cart 43, then turns the tray over to dump the battery cells, and then loads the tray onto the third transfer cart 45.

다만, 분해작업이 이루어진 일부 배터리셀은 절단이 불완전하게 이루어져, 덤핑 후에도 트레이 상에 남아있게 되는데, 상기 취출로봇(41)이 해당 배터리셀을 취출하기 위해 추가적인 절단작업을 수행한 후 제2이송대차(43)에 하적하며, 이를 위해 상기 취출로봇(41)의 작업암에는 비젼카메라, 레이저커팅기 및 셀 파지수단이 장착된다.However, some battery cells that have been disassembled are incompletely cut and remain on the tray even after dumping. After the take-out robot 41 performs an additional cut to take out the battery cells, the second transfer cart 43, and for this purpose, a vision camera, a laser cutter, and a cell holding means are mounted on the work arm of the take-out robot 41.

이와 같이 본 발명의 해체시스템은 배터리팩의 주요 해체작업이 배터리분해부(30)에서 집중적으로 이루어지고 이송 또한 단일 구성인 이송레일(11)을 통해 이루어지는 한편, 분해 후 스크랩이나 배터리셀의 반출작업도 로봇에 의해 수행되는 바, 종래기술과 달기 이송시간을 대폭 줄일 수 있다.As described above, in the disassembly system of the present invention, the main disassembly of the battery pack is intensively performed in the battery disassembly unit 30, and the transport is also performed through the single component transfer rail 11, while the disassembling and carrying out work of scrap or battery cells is performed. Since it is also performed by a robot, it is possible to significantly reduce the transfer time of the prior art and fastening.

또한, 종래기술과 같은 중복설비가 생략되어 시스템 구축 비용 절감 및 관리효율 향상을 꾀할 수 있다.In addition, since redundant facilities such as those in the prior art are omitted, system construction costs can be reduced and management efficiency can be improved.

이상에서 본 발명의 바람직한 실시예를 설명하였으나, 본 발명의 권리범위는 이에 한정되지 아니하며 본 발명의 실시예와 실질적으로 균등한 범위에 있는 것까지 본 발명의 권리범위가 미치는 것으로 이해되어야 하며, 본 발명의 정신을 벗어나지 않는 범위 내에서 당해 발명이 속하는 기술분야에서 통상의 지식을 가진 자에 의해 다양한 변형 실시가 가능하다.Although the preferred embodiments of the present invention have been described above, the scope of the present invention is not limited thereto, and it should be understood that the scope of the present invention extends to those within the scope substantially equivalent to the embodiments of the present invention. Various modifications and implementations are possible by those skilled in the art to which the invention pertains without departing from the spirit of the invention.
