Description

이차전지 실링공정용 가압장치{Pressing device for sealing secondary battery}Pressing device for sealing secondary battery}

본 발명(Disclosure)은, 이차전지 실링공정용 가압장치에 관한 것으로서, 구체적으로 이차전지 파우치의 실링공정에서 실링 위치에 관계없이 균일한 누름력을 제공할 수 있는 이차전지 실링공정용 가압장치에 관한 것이다.The present invention (Disclosure) relates to a pressurizing device for a secondary battery sealing process, and specifically, to a pressurizing device for a secondary battery sealing process capable of providing a uniform pressing force regardless of the sealing position in the sealing process of a secondary battery pouch. will be.

여기서는, 본 발명에 관한 배경기술이 제공되며, 이들이 반드시 공지기술을 의미하는 것은 아니다(This section provides background information related to the present disclosure which is not necessarily prior art).Here, background technology related to the present invention is provided, and these do not necessarily mean known technology (This section provides background information related to the present disclosure which is not necessarily prior art).

일반적인 파우치형 이차전지셀은, 양극과 음극판 및 분리막을 포함하는 전극 조립체가 적층되어, 전해액과 함께 파우치 포일(foil)에 수용된 구조이다. 파우치 포일은 그 끝단이 가열 압착되어 접합된 실링부를 갖는 봉지구조이다. A typical pouch-type secondary battery cell has a structure in which an electrode assembly including a positive electrode, a negative electrode plate, and a separator is stacked and accommodated in a pouch foil together with an electrolyte. The pouch foil is an encapsulation structure having a sealing portion joined by heating and pressing the ends thereof.

끝단이 접합되어 실링부가 형성된 파우치 포일은, 내부에 수용되는 전극 조립체를 외부의 물리적 충격으로부터 보호한다. 또한 내부에 수용되는 전극 조립체 및 전해액이 외부 환경과 화학적으로 반응하거나 외부로 누출되는 것을 방지한다. 뿐만 아니라, 노출된 파우치 포일 끝단면의 화학적 변성을 방지함으로써 파우치 포일 자체의 파손을 방지한다.The pouch foil with its ends joined to form a sealing part protects the electrode assembly accommodated therein from external physical impact. In addition, the electrode assembly and the electrolyte contained therein are prevented from chemically reacting with the external environment or leaking to the outside. In addition, the pouch foil itself is prevented from being damaged by preventing chemical modification of the exposed end of the pouch foil.

따라서 파우치형 이차전지에서 파우치 포일의 실링부는, 그 길이 방향으로 균일한 접합 특성을 가져야 한다.Therefore, in the pouch-type secondary battery, the sealing portion of the pouch foil must have uniform bonding characteristics in the longitudinal direction.

실링부의 균일한 접합 특성을 구현함에 있어서, 접합 두께의 균일성은 가장 중요한 요소중에 하나이다. In realizing the uniform bonding characteristics of the sealing portion, the uniformity of the bonding thickness is one of the most important factors.

상술한 바와 같이 실링부는, 파우치 포일이 가열 압착됨으로써 형성되므로, 실링부의 두께가 균일하지 않으면, 파우치 포일에 인가된 압력 또는 열이 불균일하다는 것을 의미한다. 실링부의 일반적인 두께 규격은 15㎛이다. As described above, since the sealing portion is formed by heating and pressing the pouch foil, if the thickness of the sealing portion is not uniform, it means that the pressure or heat applied to the pouch foil is non-uniform. The general thickness standard of the sealing part is 15㎛.

도 1은 종래의 이차전지 실링공정용 가압장치를 설명하는 도면이다.1 is a diagram illustrating a conventional pressurizing device for a secondary battery sealing process.

도 1에 나타낸 바와 같이, 종래의 이차전지 실링공정용 가압장치의 구조는, 내부에 히터(p11)가 길이 방향으로 내장된 실링 바(p10)와 실링을 위한 구동력을 실링 바(p10)에 제공하는 구동부(p20)를 포함한다. As shown in FIG. 1, the structure of a conventional pressurizing device for a secondary battery sealing process provides a sealing bar p10 in which a heater p11 is built in the longitudinal direction and a driving force for sealing to the sealing bar p10. It includes a driving unit (p20).

구동부(p20)는 실링 바(p10)의 길이방향으로 전체에 균일한 구동력을 제공하지 못하고, 특정 위치에서 구동력을 제공하는 구조이다. The driving unit p20 does not provide a uniform driving force to the entire length in the longitudinal direction of the sealing bar p10, and has a structure that provides driving force at a specific position.

실링 바(p10)의 길이방향 전체에 균일한 구동력을 제공할 수 있는 구동부(p20)의 구조는, 매우 복잡하고 비용 면에서 합리적이지 않다. The structure of the driving unit p20 capable of providing a uniform driving force to the entire longitudinal direction of the sealing bar p10 is very complex and not reasonable in terms of cost.

그런데, 실링 바(p10)의 길이가 확장되면, 실링 바(p10)에 인가되는 구동력의 불균일이 더 커진다. However, when the length of the sealing bar p10 is extended, the non-uniformity of the driving force applied to the sealing bar p10 becomes larger.

도 1을 참조하면, 구동부(p20)가 실링 바(p10)에 구동력을 제공하여 파우치 포일(1)을 가압할 때, 실링 바(p10)가 휘어진다(p10a). 휘어진 실링 바(p10a)는, 파우치 포일(1)에 균일한 압력을 인가하지 못한다.Referring to FIG. 1, when the driving unit p20 presses the pouch foil 1 by providing a driving force to the sealing bar p10, the sealing bar p10 is bent (p10a). The curved sealing bar p10a cannot apply a uniform pressure to the pouch foil 1.

따라서 가열 압착되는 파우치 포일(1)의 두께 균일성이 확보되지 못하며, 길이방향을 따른 접합 특성이 균일성을 확보하지 못하는 문제점이 있다. Therefore, there is a problem in that the uniformity of the thickness of the pouch foil 1 to be heat-pressed cannot be secured, and the uniformity of the bonding characteristics along the length direction is not secured.

한편, 최근 이차전지의 대형화되면서, 실링부의 길이가 길어지고 있다. 이에 따라 길이가 확장된 실링 바를 장착한 실링공정용 가압장치에 대한 개발이 필요한 실정이다.On the other hand, with the recent increase in the size of secondary batteries, the length of the sealing portion is getting longer. Accordingly, it is necessary to develop a pressurizing device for a sealing process equipped with a sealing bar having an extended length.

도 2는 본 발명에 따른 이차전지 실링공정용 가압장치의 일 실시형태를 설명하는 도면이다.2 is a diagram illustrating an embodiment of a pressurizing device for a secondary battery sealing process according to the present invention.

도 2를 참조하면, 본 실시형태에 따른 이차전지 실링공정용 가압장치는, 가압부(10), 가압구동 바(20), 복수의 팽창블럭(30), 실링 바(40), 센서(50) 및 제어부(60)를 포함한다. Referring to FIG. 2, the pressurizing device for a secondary battery sealing process according to the present embodiment includes a pressurizing unit 10, a pressurizing drive bar 20, a plurality of expansion blocks 30, a sealing bar 40, and a sensor 50. And a control unit 60.

가압부(10)는, 직선왕복운동을 인가하고, 가압구동 바(20)는, 가압부(10)의 말단에 구비된다.The pressing unit 10 applies a linear reciprocating motion, and the pressing drive bar 20 is provided at the end of the pressing unit 10.

복수의 팽창블럭(30)은, 가압구동 바(20)의 길이방향으로 이격되어 배치된다. The plurality of expansion blocks 30 are disposed to be spaced apart in the longitudinal direction of the pressure driving bar 20.

실링 바(40)는, 복수의 팽창블럭(30)을 기준으로 가압구동 바(20)의 반대측에 구비된다. 그 내부에 실링히터(41)가 내장되고, 실링 대상인 파우치 포일(1)과 접촉되는 가압면(42)을 가진다.The sealing bar 40 is provided on the opposite side of the pressure driving bar 20 based on the plurality of expansion blocks 30. A sealing heater 41 is embedded therein, and has a pressing surface 42 in contact with the pouch foil 1 to be sealed.

센서(50)는, 실링 바(40)에 구비되어 위치에 따른 가압면(42)의 변위 또는 누름력을 감지한다.The sensor 50 is provided on the sealing bar 40 to detect a displacement or a pressing force of the pressing surface 42 according to the position.

제어부(60)는, 센서(50)에 의해 감지된 변위 또는 누름력을 기준으로 복수의 팽창블럭(30) 각각의 팽창률을 제어한다.The controller 60 controls the expansion rate of each of the plurality of expansion blocks 30 based on the displacement or pressing force sensed by the sensor 50.

팽창률은 열팽창에 따른 원래의 길이 또는 체적에 대한 변화 비율이다.The expansion rate is the rate of change with respect to the original length or volume due to thermal expansion.

도 2에 도시된 바와 같이, 본 발명에 따른 이차전지 실링공정용 가압장치는, 실링 바(40)와 가압구동 바(20) 사이에, 복수의 팽창블럭(30)이 배치된 구조이다. As shown in FIG. 2, the pressurizing device for a secondary battery sealing process according to the present invention has a structure in which a plurality of expansion blocks 30 are disposed between the sealing bar 40 and the pressure driving bar 20.

가압구동 바(20)는, 가압부(10)가 인가하는 직선왕복운동에 의한 구동력을 복수의 팽창블럭(30)을 통하여 실링 바(40)에 인가한다. The pressure driving bar 20 applies a driving force by a linear reciprocating motion applied by the pressure unit 10 to the sealing bar 40 through the plurality of expansion blocks 30.

즉, 가압구동 바(20)와 실링 바(40)는, 팽창률이 제어되는 복수의 팽창블럭(30)을 매개로 물리적으로 연결되지만, 열적으로는 서로 차단된 구조이다.That is, the pressure driving bar 20 and the sealing bar 40 are physically connected through a plurality of expansion blocks 30 whose expansion rates are controlled, but are thermally blocked from each other.

이때 복수의 팽창블럭(30)은, 그 자리에서 팽창하되(31), 센서(50)의 측정값을 기준으로 복수의 팽창블럭(30) 각각의 팽창률을 달리함으로써, 실링 바(40)의 길이방향으로 가압구동 바(20)에 의한 구동력을 균일하게 인가한다. At this time, the plurality of expansion blocks 30 are expanded on the spot (31), but by varying the expansion rate of each of the plurality of expansion blocks 30 based on the measured value of the sensor 50, the length of the sealing bar 40 The driving force by the pressure driving bar 20 is uniformly applied in the direction.

따라서 복수의 팽창블럭(30) 각각의 팽창률을 제어함으로써 실링 바(40)이 길이방향으로 휘어지는 현상을 개선할 수 있다. Accordingly, by controlling the expansion rate of each of the plurality of expansion blocks 30, it is possible to improve the phenomenon that the sealing bar 40 is bent in the longitudinal direction.

결론적으로, 가압면(42)의 변위 또는 누름력을 기준으로, 복수의 팽창블럭(30) 각각의 팽창률이 제어됨으로써, 실링 바(40)의 휘어짐을 실시간으로 보정할 수 있다. In conclusion, by controlling the expansion rate of each of the plurality of expansion blocks 30 based on the displacement or pressing force of the pressing surface 42, the bending of the sealing bar 40 can be corrected in real time.

본 실시형태에 따른 가압부(10)는 구동력을 생성하는 실린더와 실린더에 의해 직선 왕복운동을 하는 구동축을 가질 수 있다. 이때 실린더는 유압 또는 공압으로 구동될 수 있다. The pressing unit 10 according to the present embodiment may have a cylinder that generates a driving force and a drive shaft that performs a linear reciprocating motion by the cylinder. At this time, the cylinder may be driven hydraulically or pneumatically.

도 3은 본 발명에 따른 이차전지 실링공정용 가압장치의 다른 일 실시형태에서 서브 히터를 설명하는 도면이다.3 is a view for explaining a sub-heater in another embodiment of the pressurizing device for a secondary battery sealing process according to the present invention.

본 실시형태에 따른 이차전지 실링공정용 가압장치는, 복수의 팽창블럭(30) 각각에 구비되는 복수의 서브히터(31)를 가진다. The pressurizing device for a secondary battery sealing process according to the present embodiment has a plurality of subheaters 31 provided in each of the plurality of expansion blocks 30.

이때 제어부(60)는, 센서(50)에 의해 감지된 변위 또는 누름력을 기준으로 복수의 서브히터(31)를 제어하여 복수의 팽창블럭(30)의 팽창률을 제어한다.At this time, the controller 60 controls the plurality of subheaters 31 based on the displacement or pressing force sensed by the sensor 50 to control the expansion rates of the plurality of expansion blocks 30.

즉, 복수의 팽창블럭(30) 각각을 직접 가열함으로써, 실링 바(40)의 길이방향 휘어짐을 보정하는데 필요한, 복수의 팽창블럭(30) 각각의 팽창률을 제어한다.That is, by directly heating each of the plurality of expansion blocks 30, the expansion rate of each of the plurality of expansion blocks 30, which is required to correct the longitudinal warpage of the sealing bar 40, is controlled.

도 4는 본 발명에 따른 이차전지 실링공정용 가압장치의 또 다른 일 실시형태에서 제1 단열층 및 제1 완충부재를 설명하는 도면이다.4 is a view for explaining a first heat insulating layer and a first buffer member in another embodiment of the pressurizing device for a secondary battery sealing process according to the present invention.

도 4를 참조하면, 본 실시형태에 따른 이차전지 실링공정용 가압장치는, 복수의 팽창블럭(30)과 실링 바(40) 사이에 삽입되며, 실링 바(40)와 복수의 팽창블럭(30) 사이의 열 전달을 차단하는 제1 단열층(isolator,70)을 가지진다. Referring to FIG. 4, the pressurizing device for a secondary battery sealing process according to the present embodiment is inserted between a plurality of expansion blocks 30 and a sealing bar 40, and the sealing bar 40 and the plurality of expansion blocks 30 It has a first insulating layer (isolator, 70) that blocks heat transfer therebetween.

즉 제1 단열층(70)은, 실링 바(40)로부터 복수의 팽창블럭(30)으로의 열 유입을 차단한다. That is, the first heat insulating layer 70 blocks heat inflow from the sealing bar 40 to the plurality of expansion blocks 30.

따라서 복수의 팽창블럭(30)의 온도를, 복수의 서브히터(31)에 의한 가열 작용으로 제어할 수 있으며, 복수의 팽창블럭(30)을 각각 서로 다른 팽창률로 제어할 수 있다. Accordingly, the temperature of the plurality of expansion blocks 30 can be controlled by a heating action by the plurality of sub-heaters 31, and the plurality of expansion blocks 30 can be controlled at different expansion rates, respectively.

또한, 본 실시형태에 따른 이차전지 실링공정용 가압장치는, 제1 단열층(70)과 복수의 팽창블럭(30) 사이에 삽입되어, 복수의 팽창블럭(30) 간의 온도차이를 감소시켜 제1 단열층(70)에 전달하도록 하는 제1 완충부재(80)를 가질 수 있다.In addition, the pressurizing device for a secondary battery sealing process according to the present embodiment is inserted between the first heat insulating layer 70 and the plurality of expansion blocks 30 to reduce the temperature difference between the plurality of expansion blocks 30 to reduce the first heat insulating layer. It may have a first buffer member 80 to be transmitted to the 70.

즉 제1 완충부재(80)는, 복수의 팽창블럭(30) 각각을 가열하여 서로 다른 팽창률을 나타낼 때, 복수의 팽창블럭(30)이 배열된 방향으로, 제1 단열층(70)의 온도 변화를 감소시킨다. That is, when the first buffer member 80 heats each of the plurality of expansion blocks 30 to show different expansion rates, the temperature of the first heat insulation layer 70 changes in the direction in which the plurality of expansion blocks 30 are arranged. Reduce

제1 완충부재(80)의 기능을 구체적으로 설명하면, 복수의 서브히터(31)를 작동하여 복수의 팽창블럭(30)을 가열하면, 제1 단열층(70)이 복수의 팽창블럭(30)과 접하는 부위와 접하지 않는 부위에서, 온도가 급격한 차이가 나타난다. When the function of the first buffer member 80 is specifically described, when the plurality of subheaters 31 are operated to heat the plurality of expansion blocks 30, the first heat insulating layer 70 becomes the plurality of expansion blocks 30. In the area in contact with and in the area not in contact, a sharp difference in temperature appears.

이러한 온도 차이는 제1 단열층(70)의 길이 방향으로 신축량이 달라지게 하며, 크랙(crack) 또는 파손될 가능성이 있다. This difference in temperature causes the amount of expansion and contraction in the longitudinal direction of the first heat insulating layer 70 to vary, and there is a possibility of cracking or breaking.

제1 완충부재(80)는, 제1 단열층(70)과 복수의 팽창블럭(30) 사이에 급격한 온도 변화를 감소시킴으로써, 제1 단열층(70)의 위치에 따른 온도구배를 완만하게 한다. The first buffer member 80 reduces a sudden change in temperature between the first heat insulating layer 70 and the plurality of expansion blocks 30, thereby smoothing the temperature gradient according to the position of the first heat insulating layer 70.

따라서 제1 완충부재(80)는, 바람직하게는 열전도성이 좋은 금속판으로 구성됨으로써 복수의 팽창블럭(30)에서 전달된 열을, 그 길이방향으로 빠르게 분산시킬 수 있다. Therefore, the first buffer member 80 is preferably formed of a metal plate having good thermal conductivity, so that heat transferred from the plurality of expansion blocks 30 can be rapidly dissipated in the longitudinal direction.

길이방향으로 분산된 열은, 제1 단열층(70)의 길이방향으로 균일하게 열을 전달하여, 상술한 바와 같은 온도차이에 따른 제1 단열층(70)의 파손 현상을 방지한다.The heat dispersed in the longitudinal direction transfers heat uniformly in the longitudinal direction of the first heat insulating layer 70, thereby preventing the first heat insulating layer 70 from being damaged due to the temperature difference as described above.

도 5는 본 발명에 따른 이차전지 실링공정용 가압장치의 또 다른 일 실시형태에서 실링히터를 제어하여 복수의 팽창블럭의 팽창률을 제어하는 방법을 설명하는 도면이다. 5 is a view for explaining a method of controlling the expansion rate of a plurality of expansion blocks by controlling a sealing heater in another embodiment of a pressurizing device for a secondary battery sealing process according to the present invention.

도 5를 참조하면, 본 실시형태에 따른 이차전지 실링공정용 가압장치에서, 복수의 팽창블럭(30)은 동일한 온도에서 팽창률을 달리하는 것으로 구비되며, 제어부(60)는, 실링히터(41)를 제어하여 복수의 팽창블럭(30)의 팽창률을 제어한다. Referring to FIG. 5, in the pressurizing device for a secondary battery sealing process according to the present embodiment, a plurality of expansion blocks 30 are provided to have different expansion rates at the same temperature, and the control unit 60 includes a sealing heater 41 To control the expansion rate of the plurality of expansion blocks 30.

이때, 복수의 팽창블럭(30)은, 바람직하게는 가압부(10)로부터 멀어지는 방향으로 팽창률이 커지도록 배치된다.At this time, the plurality of expansion blocks 30 are preferably arranged to increase the expansion rate in a direction away from the pressing unit 10.

따라서 이 경우의 본 발명에 따른 이차전지 실링공정용 가압장치는 , 바람직하게는, 제1 단열층(70)와 제1 완충부재(80) 및 제2 단열층(91)과 제2 완충부재(92)를 구비한다.Therefore, in this case, the pressurizing device for a secondary battery sealing process according to the present invention preferably includes a first heat insulating layer 70 and a first buffer member 80 and a second heat insulating layer 91 and a second buffer member 92 Equipped.

반면에 복수의 팽창블럭(30)이 실링히터(41)로부터 생성되는 열로 가열되면, 복수의 팽창블럭(30)은, 가압구동 바(20)와의 경계는 단열처리되어야 하며, 실링 바(40)와는 열전달이 원활해야 한다.

도 7은 본 발명에 따른 이차전지 실링공정용 가압장치의 또 다른 일 실시형태에서, 팽창블럭이 육면체인 경우의 팽창블럭의 팽창 작용을 설명하는 도면이며, 도 8은 도 7에서 팽창블럭이 원통형인 경우의 팽창블럭의 팽창 작용을 설명하는 도면이다.7 is a view for explaining the expansion action of the expansion block when the expansion block is a hexahedron in another embodiment of the pressurization device for a secondary battery sealing process according to the present invention. It is a diagram explaining the expansion action of the expansion block in the case of.

도 7을 참조하면, 본 실시형태에 따른 복수의 팽창블럭(30)은 육면체 형상이다. 팽창블럭(30)의 팽창하면 수직 방향의 팽창 작용(a1)과 그외 방향의 팽창 작용(b1)으로 나눌 수 있다. Referring to FIG. 7, the plurality of expansion blocks 30 according to the present embodiment have a hexahedral shape. When the expansion block 30 is expanded, it can be divided into a vertical expansion action (a1) and an expansion action (b1) in the other direction.

도 7에서 확인할 수 있듯이, 육면체형상의 복수의 팽창블럭(30)을 채용하면, 수직 방향의 팽창 작용(a1)은 실링 바(40)의 휘어짐 보정에 직접 작용한다. As can be seen in FIG. 7, when a plurality of expansion blocks 30 in a hexahedral shape are employed, the expansion action a1 in the vertical direction directly acts on the correction of the warpage of the sealing bar 40.

그러나 그외 방향의 팽창 작용(b1)은, 그 벡터(vector) 성분중 수직 방향의 벡터 성분만 실링 바(40)의 휘어짐 보정에 작용한다. However, in the expansion action b1 in other directions, only the vector component in the vertical direction among the vector components acts to correct the warpage of the sealing bar 40.

한편, 도 8을 참조하면, 복수의 팽창블럭(30)이 원통형상이며, 이때 가압구동 바(20)와 실링 바(40)는, 원통형상의 복수의 팽창블럭(30)과 맞춤되는 함몰부(21)를 갖는다. On the other hand, referring to FIG. 8, the plurality of expansion blocks 30 are cylindrical, and at this time, the pressure driving bar 20 and the sealing bar 40 are recessed portions ( 21).

도 8에서 확인할 수 있듯이, 도 7과 비교하여 그외 방향의 팽창 작용(b2)에서 실링 바(40)의 휨현상에 작용하는 벡터 성분이 더 크다. As can be seen in FIG. 8, compared to FIG. 7, the vector component acting on the bending phenomenon of the sealing bar 40 in the expansion action (b2) in the other direction is larger.

만일, 도 7에서, 육면체 형상의 팽창블럭(30)을 사용하고, 가압구동 바(20)와 실링 바(40)에 육면체 형상의 함몰부가 형성되면, 도 8과 같이 그외 방향의 팽창 작용(b1)이 실링 바(40)의 휘어짐 보정에 더 그게 작용할 수 있다. If, in FIG. 7, a hexahedral expansion block 30 is used, and a hexahedral depression is formed in the pressure driving bar 20 and the sealing bar 40, the expansion action in the other direction (b1) as shown in FIG. ) May further act on the correction of the warpage of the sealing bar 40.

그러나 이렇게 되면, 팽창블럭(30)의 돌출된 모서리와 그에 맞춤되는 가압가동 바(20)와 실링 바(40)의 모서리에 팽창력이 집중되어, 파손의 위험이 발생한다. However, in this case, the expansion force is concentrated in the protruding corner of the expansion block 30 and the corners of the pressing movable bar 20 and the sealing bar 40 fitted thereto, resulting in a risk of damage.

따라서 본 발명에 따른 이차전지 실링공정용 가압장치에서, 가압구동 바(20)와 실링 바(40)는, 바람직하게는, 복수의 팽창블럭(30)의 일부가 맞춤되는 함몰부가 형성된다. 이때, 복수의 팽창블럭(30)은, 바람직하게는, 원통형형상이다. Therefore, in the pressurizing apparatus for a secondary battery sealing process according to the present invention, the pressure driving bar 20 and the sealing bar 40 are preferably formed with recesses in which some of the plurality of expansion blocks 30 are aligned. At this time, the plurality of expansion blocks 30 are preferably cylindrical in shape.
