다품종 대응형 2차전지 극성변환 충방전장치 {Multiproduct corresponding type secondary battery polarity charge and discharge device}Technical Field [0001] The present invention relates to a multi-product type secondary battery polarity charge and discharge device,

본 발명은 다품종 대응형 2차전지 극성변환 충방전장치에 관한 것으로, 더욱 상세하게는 2차전지의 극성에 구속되지 않고 2차전지탭을 접속시켜 다양한 형태의 2차전지를 충방전시킬 수 있는 다품종 대응형 2차전지 극성변환 충방전장치에 관한 것이다.

It is used for portable devices such as smart phones, netbooks, notebooks, electric vehicles and energy storage devices do.

또한, 스마트 휴대형 기기의 발달로 인한 2차전지의 수요는 점차 확대되고 있으며, 다양한 디자인의 기기들이 출시되면서 전지의 형태 및 크기 종류도 다양하게 출시되고 있다.In addition, the demand for rechargeable batteries due to the development of smart portable devices is gradually expanding, and various types of batteries are being released with various designs.

이러한 2차전지는 충방전 공정을 거쳐 제품으로 출시되는데 충방전 공정은 2차전지에 일정한 전력을 공급하여 충전하고 방전시키는 작업을 반복하며 2차전지의 충전용량 및 제품특성을 확인하는 공정이다.The secondary battery is discharged through a charging / discharging process. The charging / discharging process repeats charging and discharging operations by supplying a constant power to the secondary battery and confirming the charging capacity and product characteristics of the secondary battery.

이때, 2차전지의 충방전 공정에서 정해진 전류치를 얼마나 정밀하게 지속적으로 충전하고 방전해 줄 수 있는지가 가장 중요하다.At this time, it is most important how precisely and continuously the charged current value can be charged and discharged in the charging / discharging process of the secondary battery.

이를 위해서는 2차전지의 충방전 공정에서 2차전지의 충방전을 위한 프로브 접속과 극성을 얼마나 정확하게 센싱하고, 제어할 수 있는지가 중요한데, 종래에는 사람이나 기계장치에 의해 공정에서 극성이 바뀌지 않게 공정을 일률적으로 통제하였으며 2차전지의 형태와 극성의 위치에 따라 2차전지의 위치를 바꾸는 등에 많은 불필요한 작업이 이루어지면서 생산 효율성 및 측정 정밀도가 저하되는 문제가 있다.For this purpose, it is important to precisely sense and control the connection and polarity of the probe for charging and discharging the secondary battery in the charging and discharging process of the secondary battery. Conventionally, in order to prevent the polarity of the process from changing by the human or mechanical device, And there is a problem that the production efficiency and measurement precision are lowered due to a lot of unnecessary work such as changing the position of the secondary battery depending on the shape of the secondary battery and the position of the polarity.

또한, 2차전지의 충방전 작업은 충방전 회로와 2차전지 사이에 프로브를 직렬연결하여 사용하게 되는데 션트 저항에 의한 전압강하로 인하여 충방전 공정 간 2차전지 또는 장치의 전압 손실이 발생하고 2차전지의 충방전 전류량의 측정오차가 발생하는 문제가 있었다.

좌우이동부재(400)는 승하강부재(300)의 일면에 연결설치되며 승하강부재(300)와 동일하게 리미트스위치(410)가 구비된다.The left and right movable member 400 is connected to one surface of the lifting member 300 and includes a limit switch 410 in the same manner as the lifting member 300.

또한, 좌우이동부재(400)는 승하강부재(300)를 좌우측으로 이동시키는 부재로 전진과 후진이 가능한 실린더를 사용할 수 있다.Also, the left and right movable member 400 can be a cylinder that can move forward and backward by moving the lifting member 300 to the left and right.

이때, 좌우이동부재(400)는 승하강부재(300)와 결합되어 승하강부재(300)에 결합된 하부 및 상부접속단자(100,200)가 2차전지탭을 세밀하게 감지하게 된다.At this time, the left and right shifting member 400 is coupled with the lifting member 300 so that the lower and upper connection terminals 100 and 200 coupled to the lifting member 300 closely detect the secondary battery tab.

즉, 승하강부재(300)와 좌우이동부재(400)는 수직축선상의 가상의 x축과 y축으로 동작하는 2선동작방식을 사용함으로써 2차전지탭의 잡촉간 안정성을 제공하고, 기계적 정밀도를 향상시키게 된다.That is, the up-and-down moving member 300 and the left-and-right moving member 400 use the two-wire operation method operating on the imaginary x- and y-axes on the vertical axis, .

즉, 수치제어 모터(500)의 접근거리는 저장된 2차전지 정보와 충방전 시키기 위한 2차전지의 정보가 저장되어 있지 않거나, 이물질로 인한 2차전지의 품종정보가 명확하지 않을 때를 대비하여 에러에 대한 피드백 신호를 제어부로 전송할 수 있다.That is, the approach distance of the numerical control motor 500 may be determined by comparing the stored secondary battery information and information of the secondary battery for charging / discharging, or if the type information of the secondary battery due to the foreign substance is not clear, To the control unit.

또한, 피드백 신호는 단순한 오류에 대한 수정을 요하는 공정을 진행할 뿐만 아니라 2차전지탭의 접속위치와 접속상태에 대한 오류를 수정하기위해 반복적으로 접속위치를 조정하도록 제어할 수 있다.In addition, the feedback signal can be controlled so as to repeatedly adjust the connection position in order to correct errors in the connection position and connection state of the secondary battery tab as well as in a process that requires correction for a simple error.

이는 2차전지충방전시 발생하는 오류에 대한 스파크 발생을 최소화 하여 2차전지를 폭발의 위험으로 부터 보호하기 위함이다.This is to protect the secondary battery from the risk of explosion by minimizing the spark from errors caused by the discharge of the secondary battery.

이하 본 발명에 실시 예에 따른 다품종 대응형 2차전지 극성변환 충방전장치를 설명하면 다음과 같다.Hereinafter, the multi-product type secondary battery polarity conversion charge / discharge device according to an embodiment of the present invention will be described.

접속위치가 확인된 2차전지탭에 하부 및 상부접속단자가 접속되어 2차전지의 극성을 확인한다.The lower and upper connection terminals are connected to the secondary battery tab whose connection position is confirmed, and the polarity of the secondary battery is confirmed.

이때, 하부 및 상부접속단자(100,200)에 설치된 양극배선과 음극배선을 이용하여 각각의 스위치에 의해 극성을 확인하게 된다.At this time, the polarity is confirmed by the respective switches using the positive electrode wiring and the negative electrode wiring provided on the lower and upper connection terminals 100 and 200.

이는 하부 및 상부접속단자(100,200)에 설치된 스위치에 의해 2차전지탭과 접속된 접속단자를 통해 극성이 확인되도록 함과 동시에 충방전 극성이 미확인되어 일어날 수 있는 음극과 양극의 충돌을 막기 위함이다.This allows the polarity to be confirmed through the connection terminal connected to the secondary battery tab by the switch provided on the lower and upper connection terminals 100 and 200 and prevents the collision between the cathode and the anode which may occur due to the uncharacterized charge / discharge polarity .

극성결과에 따라 접속이 완료되면 하부 및 상부접속단자가 2차전지탭에 접속되어 충방전에 필요한 전압과 전류의 진행방향에 따라 2차전지를 충방전하는 것이다.When the connection is completed according to the polarity result, the lower and upper connection terminals are connected to the secondary battery tab to charge and discharge the secondary battery according to the direction of the voltage and current required for charging and discharging.

그러므로 본 발명의 실시 예에 따른 다품종 대응형 2차전지 극성변환 충방전장치은 2차전지의 극성을 양극과 음극에 구속되지 않고 테스트를 진행하여 충방전 공정의 효율성과 생산성을 상승시킬 수 있다.Therefore, according to the embodiment of the present invention, the polarity of the secondary battery can be tested without restricting the polarity of the secondary battery to the anode and the cathode, thereby improving the efficiency and productivity of the charging and discharging process.

또한, 안정적인 접지를 통해 전압을 안정적으로 공급함으로써 전류량의 측정오차와 측정 정밀도를 높일 수 있어 불량률을 줄일 수 있다.In addition, by stably supplying the voltage through the stable grounding, it is possible to increase the measurement error and the measurement accuracy of the amount of current, thereby reducing the defect rate.
