However, the positive electrode current collector may extend in a direction shifted from a direction orthogonal to the direction in which the flat surface of the cover plate extends. In this case, when the positive electrode current collector is inserted between the positive electrode tab portions, the positive electrode current collector collides with the positive electrode tab portion or the positive electrode, and the positive electrode current collector is interposed between the positive electrode tab portions. In some cases, it could not be inserted easily. Similarly to the positive electrode current collector, the negative electrode current collector collides with the negative electrode tab part or the negative electrode, and the negative electrode current collector cannot be easily inserted between the negative electrode tab parts. was there.

以上の構成を備える電池製造装置１の動作について、図９から図１３を用いて以下に詳述する。   The operation of the battery manufacturing apparatus 1 having the above configuration will be described in detail below with reference to FIGS. 9 to 13.

図９は、正極集電体矯正部２０を正極集電体２００に嵌合させるとともに、負極集電体矯正部４０を負極集電体３００に嵌合させた状態を示す図である。図９において、図２から８で示した方向に合わせて、右方に向かう向きをＸプラス方向とし、紙面手前向きをＹプラス方向とし、下方に向かう向きをＺプラス方向とする。正極集電体矯正部２０は、Ｚ方向に延在する基部２１と、基部２１からＸマイナス方向に突出する突出部２２と、を備え、負極集電体矯正部４０は、Ｚ方向に延在する基部４１と、基部４１からＸプラス方向に突出する突出部４２と、を備える。   FIG. 9 is a diagram illustrating a state in which the positive electrode current collector correction part 20 is fitted to the positive electrode current collector 200 and the negative electrode current collector correction part 40 is fitted to the negative electrode current collector 300. In FIG. 9, in accordance with the directions shown in FIGS. 2 to 8, the rightward direction is the X plus direction, the front side of the paper is the Y plus direction, and the downward direction is the Z plus direction. The positive electrode current collector correction portion 20 includes a base portion 21 extending in the Z direction and a protruding portion 22 protruding from the base portion 21 in the X minus direction, and the negative electrode current collector correction portion 40 extends in the Z direction. And a protruding portion 42 that protrudes from the base 41 in the X plus direction.

電池製造装置１は、まず、図９に示すように、正極集電体２００のコの字形の凹部に突出部２２をはめこむとともに、負極集電体３００のコの字形の凹部に突出部４２をはめこむ。これによれば、正極集電体矯正部２０が正極集電体２００に嵌合されるとともに、負極集電体矯正部４０が負極集電体３００に嵌合されることになる。   First, as shown in FIG. 9, the battery manufacturing apparatus 1 inserts the protrusion 22 into the U-shaped recess of the positive electrode current collector 200, and also protrudes into the U-shaped recess of the negative electrode current collector 300. Fit. According to this, the positive electrode current collector correction part 20 is fitted to the positive electrode current collector 200, and the negative electrode current collector correction part 40 is fitted to the negative electrode current collector 300.

図１０は、正極集電体２００および負極集電体３００の位置ずれを矯正している状態を示す側面図である。図１０において、図２から９で示した方向に合わせて、右方に向かう向きをＸプラス方向とし、上方に向かう向きをＹプラス方向とし、紙面手前向きをＺプラス方向とする。正極集電体矯正部２０の基部２１および負極集電体矯正部４０の基部４１は、図９を用いて上述したようにＺ方向に延在しているだけでなく、図１０に示すようにＹ方向にも延在している。また、正極集電体矯正部２０の突出部２２および負極集電体矯正部４０の突出部４２は、図９を用いて上述したようにＺ方向に延在しているだけでなく、後述の図１３に示すようにＹ方向にも延在している。   FIG. 10 is a side view showing a state in which the positional deviation between the positive electrode current collector 200 and the negative electrode current collector 300 is corrected. In FIG. 10, in accordance with the directions shown in FIGS. 2 to 9, the rightward direction is the X plus direction, the upward direction is the Y plus direction, and the front side of the drawing is the Z plus direction. The base portion 21 of the positive electrode current collector correction portion 20 and the base portion 41 of the negative electrode current collector correction portion 40 not only extend in the Z direction as described above with reference to FIG. 9, but also as shown in FIG. It also extends in the Y direction. Further, the protruding portion 22 of the positive electrode current collector correcting portion 20 and the protruding portion 42 of the negative electrode current collector correcting portion 40 not only extend in the Z direction as described above with reference to FIG. As shown in FIG. 13, it also extends in the Y direction.

電池製造装置１は、次に、図１０に示すように、正極集電体２００に嵌合されている正極集電体矯正部２０を、蓋部材４００のうち正極集電体２００が固定されている部分からＹマイナス方向に延伸する線分に沿って、所定位置に配置するとともに、負極集電体３００に嵌合されている負極集電体矯正部４０を、蓋部材４００のうち負極集電体３００が固定されている部分からＹマイナス方向に延伸する線分に沿って、所定位置に配置する。これによれば、正極集電体矯正部２０および負極集電体矯正部４０により、正極集電体２００および負極集電体３００の位置ずれが矯正され、正極集電体２００および負極集電体３００が、蓋部材４００の平面が延在する向きと直交する向きに延在することになる。   Next, as shown in FIG. 10, the battery manufacturing apparatus 1 is configured such that the positive electrode current collector correcting portion 20 fitted to the positive electrode current collector 200 is fixed to the positive electrode current collector 200 of the lid member 400. The negative electrode current collector correction portion 40 that is disposed at a predetermined position along the line segment extending in the Y minus direction from the existing portion and is fitted to the negative electrode current collector 300 is connected to the negative electrode current collector of the lid member 400. It arrange | positions in a predetermined position along the line segment extended in the Y minus direction from the part to which the body 300 is fixed. According to this, the positive electrode current collector correcting unit 20 and the negative electrode current collector correcting unit 40 correct the misalignment of the positive electrode current collector 200 and the negative electrode current collector 300, and the positive electrode current collector 200 and the negative electrode current collector are corrected. 300 extends in a direction orthogonal to the direction in which the plane of the lid member 400 extends.

また、電池製造装置１は、正極集電体２００の端部（Ｙマイナス方向側の端部）に正極側誘導部１１を装着するとともに、負極集電体３００の端部（Ｙマイナス方向側の端部）に負極側誘導部３１を装着する。なお、正極側誘導部１１のうち、正極集電体２００に装着されている端部（Ｙプラス方向側の端部）を基端部とし、基端部と対向する端部（Ｙマイナス方向側の端部）を先端部とすると、正極側誘導部１１の先端部は、正極側誘導部１１の基端部と比べて細く形成されている。また、負極側誘導部３１のうち、負極集電体３００に装着されている端部（Ｙプラス方向側の端部）を基端部とし、基端部と対向する端部（Ｙマイナス方向側の端部）を先端部とすると、負極側誘導部３１の先端部は、負極側誘導部３１の基端部と比べて細く形成されている。   In addition, the battery manufacturing apparatus 1 attaches the positive electrode side induction portion 11 to the end portion (end portion on the Y minus direction side) of the positive electrode current collector 200 and the end portion (on the Y minus direction side) of the negative electrode current collector 300. The negative electrode side guide portion 31 is attached to the end portion. In addition, among the positive electrode side induction | guidance | derivation parts 11, let the edge part (end part on the Y plus direction side) with which the positive electrode collector 200 was mounted | worn be a base end part, and the edge part (Y minus direction side) facing a base end part The tip end portion of the positive electrode side guide portion 11 is formed thinner than the base end portion of the positive electrode side guide portion 11. Further, of the negative electrode side induction portion 31, an end portion (Y positive direction side end portion) attached to the negative electrode current collector 300 is a base end portion, and an end portion (Y negative direction side) facing the base end portion. The tip end portion of the negative electrode side guide portion 31 is formed thinner than the base end portion of the negative electrode side guide portion 31.

電池製造装置１は、次に、正極集電体矯正部２０および負極集電体矯正部４０により正極集電体２００および負極集電体３００が矯正されている状態において、正極側挿入部１２により、正極側誘導部１１の装着されている端部側から正極集電体２００を、対に設けられた正極のタブ部１１３ａ、１１３ｂの間に挿入するとともに、負極側挿入部３２により、負極側誘導部３１の装着されている端部側から負極集電体３００を、対に設けられた負極のタブ部１２３ａ、１２３ｂの間に挿入する。これによれば、図１１、図１２に示すように、正極集電体２００が、正極集電体矯正部２０により矯正されている状態で、対に設けられた正極のタブ部１１３ａ、１１３ｂの間に挿入されるとともに、負極集電体３００が、負極集電体矯正部４０により矯正されている状態で、対に設けられた負極のタブ部１２３ａ、１２３ｂの間に挿入されることになる。   Next, in the state where the positive electrode current collector 200 and the negative electrode current collector 300 are corrected by the positive electrode current collector correcting unit 20 and the negative electrode current collector correcting unit 40, the battery manufacturing apparatus 1 is The positive electrode current collector 200 is inserted between the tab portions 113a and 113b of the positive electrode provided in the pair from the end side where the positive electrode side induction portion 11 is mounted, and the negative electrode side insertion portion 32 The negative electrode current collector 300 is inserted between the tab portions 123a and 123b of the negative electrode provided in the pair from the end side where the induction unit 31 is mounted. According to this, as shown in FIGS. 11 and 12, the positive electrode current collector 200 is corrected by the positive electrode current collector correction unit 20, and the positive electrode tab portions 113 a and 113 b provided in the pair are connected. In addition, the negative electrode current collector 300 is inserted between the tab portions 123a and 123b of the negative electrode provided in the pair while being corrected by the negative electrode current collector correcting unit 40. .

図１１は、対に設けられた正極のタブ部１１３ａ、１１３ｂの間に正極集電体２００を挿入するとともに、対に設けられた負極のタブ部１２３ａ、１２３ｂの間に負極集電体３００を挿入した状態を示す側面図である。図１１において、図２から１０で示した方向に合わせて、右方に向かう向きをＸプラス方向とし、上方に向かう向きをＹプラス方向とし、紙面手前向きをＺプラス方向とする。   In FIG. 11, the positive electrode current collector 200 is inserted between the positive electrode tab portions 113a and 113b provided in the pair, and the negative electrode current collector 300 is inserted between the negative electrode tab portions 123a and 123b provided in the pair. It is a side view which shows the state inserted. In FIG. 11, in accordance with the directions shown in FIGS. 2 to 10, the rightward direction is the X plus direction, the upward direction is the Y plus direction, and the front side is the Z plus direction.

図１２は、図１１のＢ−Ｂ断面における断面図である。図１２において、図２から１１で示した方向に合わせて、右方に向かう向きをＸプラス方向とし、紙面手前向きをＹプラス方向とし、下方に向かう向きをＺプラス方向とする。   12 is a cross-sectional view taken along the line BB of FIG. In FIG. 12, in accordance with the directions shown in FIGS. 2 to 11, the rightward direction is the X plus direction, the front side of the paper is the Y plus direction, and the downward direction is the Z plus direction.

なお、上述のように、正極側誘導部１１の先端部が、正極側誘導部１１の基端部と比べて細く形成されているため、正極側誘導部１１が正極集電体２００の端部に装着されていない場合と比べて、対に設けられた正極のタブ部１１３ａ、１１３ｂの間への正極集電体２００の挿入が容易になる。また、正極集電体２００が、正極集電体矯正部２０により矯正されている状態で、対に設けられた正極のタブ部１１３ａ、１１３ｂの間に挿入される。以上によれば、正極集電体２００が正極１１０やクリップ１４１や正極のタブ部１１３ａ、１１３ｂに接触してしまうのを防止することができる。   As described above, since the distal end portion of the positive electrode side induction portion 11 is formed thinner than the proximal end portion of the positive electrode side induction portion 11, the positive electrode side induction portion 11 is the end portion of the positive electrode current collector 200. Compared to the case where the positive electrode current collector 200 is not attached to the positive electrode current collector 200, the positive electrode current collector 200 is easily inserted between the positive electrode tab portions 113a and 113b provided in the pair. In addition, the positive electrode current collector 200 is inserted between the positive electrode tab portions 113a and 113b provided in the pair in a state where the positive electrode current collector 200 is corrected by the positive electrode current collector correcting unit 20. According to the above, it is possible to prevent the positive electrode current collector 200 from coming into contact with the positive electrode 110, the clip 141, and the positive electrode tab portions 113a and 113b.

また、上述のように、負極側誘導部３１の先端部が、負極側誘導部３１の基端部と比べて細く形成されているため、負極側誘導部３１が負極集電体３００の端部に装着されていない場合と比べて、対に設けられた負極のタブ部１２３ａ、１２３ｂの間への負極集電体３００の挿入が容易になる。また、負極集電体３００が、負極集電体矯正部４０により矯正されている状態で、対に設けられた負極のタブ部１２３ａ、１２３ｂの間に挿入される。以上によれば、負極集電体３００が負極１２０やクリップ１４２や負極のタブ部１２３ａ、１２３ｂに接触してしまうのを防止することができる。   Further, as described above, since the distal end portion of the negative electrode side induction portion 31 is formed thinner than the proximal end portion of the negative electrode side induction portion 31, the negative electrode side induction portion 31 is the end portion of the negative electrode current collector 300. As compared with the case where the negative electrode current collector 300 is not attached to the negative electrode current collector 300, the negative electrode current collector 300 can be easily inserted between the tab portions 123a and 123b of the negative electrode provided in the pair. Further, the negative electrode current collector 300 is inserted between the tab portions 123 a and 123 b of the negative electrode provided in the pair in a state where the negative electrode current collector 300 is corrected by the negative electrode current collector correcting unit 40. According to the above, it is possible to prevent the negative electrode current collector 300 from coming into contact with the negative electrode 120, the clip 142, or the tab portions 123a and 123b of the negative electrode.

また、正極集電体２００および負極集電体３００の双方は、上述のように蓋部材４００に固定されている。このため、正極集電体２００と負極集電体３００とが蓋部材４００を介して一体に動くことになるので、正極側挿入部１２および負極側挿入部３２は、同一の構成となる。ただし、正極集電体２００と負極集電体３００とが、蓋部材４００のような同一の部材に固定されていない場合には、正極集電体２００と負極集電体３００とがそれぞれ独立して動くことになるので、正極側挿入部１２および負極側挿入部３２は、互いに異なる構成となる。   Further, both the positive electrode current collector 200 and the negative electrode current collector 300 are fixed to the lid member 400 as described above. For this reason, since the positive electrode current collector 200 and the negative electrode current collector 300 move together via the lid member 400, the positive electrode side insertion portion 12 and the negative electrode side insertion portion 32 have the same configuration. However, when the positive electrode current collector 200 and the negative electrode current collector 300 are not fixed to the same member such as the lid member 400, the positive electrode current collector 200 and the negative electrode current collector 300 are independent from each other. Therefore, the positive electrode side insertion portion 12 and the negative electrode side insertion portion 32 have different configurations.

電池製造装置１は、次に、図１３に示すように、対に設けられた正極のタブ部１１３ａ、１１３ｂの間に挿入されている正極集電体２００から、正極側取り外し部１３により正極集電体矯正部２０を取り外すとともに、正極側除去部１４により正極側誘導部１１を取り除く。また、電池製造装置１は、対に設けられた負極のタブ部１２３ａ、１２３ｂの間に挿入されている負極集電体３００から、負極側取り外し部３３により負極集電体矯正部４０を取り外すとともに、負極側除去部３４により負極側誘導部３１を取り除く。   Next, as shown in FIG. 13, the battery manufacturing apparatus 1 uses the positive electrode side removal unit 13 to collect the positive electrode current from the positive electrode current collector 200 inserted between the tab portions 113 a and 113 b of the positive electrode provided in the pair. While removing the electric body correction | amendment part 20, the positive electrode side induction | guidance | derivation part 11 is removed by the positive electrode side removal part 14. FIG. In addition, the battery manufacturing apparatus 1 removes the negative electrode current collector correction portion 40 from the negative electrode current collector 300 inserted between the negative electrode tab portions 123a and 123b provided in the pair by the negative electrode side removing portion 33. Then, the negative electrode side induction unit 31 is removed by the negative electrode side removal unit 34.

図１３は、正極集電体２００から正極集電体矯正部２０および正極側誘導部１１を除去するとともに、負極集電体３００から負極集電体矯正部４０および負極側誘導部３１を除去した状態を示す側面図である。図１１において、図２から１２で示した方向に合わせて、右方に向かう向きをＸプラス方向とし、上方に向かう向きをＹプラス方向とし、紙面手前向きをＺプラス方向とする。   In FIG. 13, the positive electrode current collector correcting part 20 and the positive electrode side induction part 11 are removed from the positive electrode current collector 200, and the negative electrode current collector correction part 40 and the negative electrode side induction part 31 are removed from the negative electrode current collector 300. It is a side view which shows a state.
