Description

図2及び図3は、この実施形態に係るシート状量子電池1(以下、単に「シート状電池1」とも記す)を示す図である。図2は、シート状電池1の正面図であり、図3は、図のシート状電池1のA−A線断面図である。 2 and 3 are views showing a sheet-like quantum cell 1 (hereinafter also simply referred to as “sheet-like battery 1”) according to this embodiment. FIG. 2 is a front view of the sheet battery 1, and FIG. 3 is a cross-sectional view taken along line AA of the sheet battery 1 of FIG. 2 .

そして、一対の折曲部125a、125bの間にシート状電池1が通っている状態で、回動部128を支持面129a、129bがシート状電池1と接する方向に回転させ、支持面部129a、129bとシート状電池1が接した後さらに所定角度回転させる。これにより折曲部125a、125bの先端部124a、124bによりシート状電池1が折り曲げられる。さらに、折曲部125a、125bの斜面部127a、127bと略平行なプレス面を有するプレス部126a、126bが斜面部127a、127bに向けて移動してシート状電池1を押圧する。これにより、折曲部125a、125bの先端部124a、124bの位置するところが折り目となりシート状電池1は折り曲げられる。 The pair of bent portions 125a, in a state where the sheet-like battery 1 passes through between 125b, the support surface portion 129a of the rotating portion 128 is rotated in the direction of 129b is in contact with the sheet-like battery 1, the support surface portion 129a 129b and the sheet battery 1 are in contact with each other and further rotated by a predetermined angle. Thereby, the sheet-like battery 1 is bent by the front end portions 124a and 124b of the bent portions 125a and 125b. Further, the press portions 126a and 126b having press surfaces substantially parallel to the slope portions 127a and 127b of the bent portions 125a and 125b move toward the slope portions 127a and 127b to press the sheet-like battery 1. Thereby, the position where the front-end | tip parts 124a and 124b of the bending parts 125a and 125b become a crease | fold, and the sheet-like battery 1 is bent.

なお、折り畳まれたシート状電池1の上面と下面については、その電極層に応じた電極端子板が配置される。例えば蛇腹状電池1の上面及び下面が負極層3の場合は、蛇腹状電池1の下面の下に負極端子板22が配置され、上面の上に負極端子板22が載せられる。 In addition, about the upper surface and lower surface of the folded sheet-like battery 1, the electrode terminal board according to the electrode layer is arrange | positioned. For example, if upper and lower surfaces of the bellows-shaped battery 1 is of the negative electrode layer 3, the negative electrode terminal plate 22 is disposed under the lower surface of the bellows-like battery 1, the negative terminal plate 22 is placed on the top surface.

なお、試験装置100は、上記構成要素以外に他の構成要素を含むものであっても良い。例えば、電池折畳部51は、シート状電池1の張力を制御するための機構部や、シール状電池1の幅方向の位置を検知して所定位置に電気接続用の電極端子を固定するための機構部等を備えるようにしても良い。また、シート状電池1を保持して送り出すためのローラを適宜設けてもよい。 The test apparatus 100 may include other components in addition to the above components. For example, the battery folding part 51 detects a position in the width direction of the sealing battery 1 by fixing a mechanism part for controlling the tension of the sheet battery 1 and fixes the electrode terminal for electrical connection at a predetermined position. You may make it provide this mechanism part. Further, a roller for holding and feeding the sheet battery 1 may be provided as appropriate.

そして、一対の折曲部525a、525bの間にシート状電池1Aが通っている状態で、前記電極端子板供給部がシート状電池1Aの負極層3側に負極端子板22を近接させ、正極層2側に正極端子板21を近接させる。その状態で挟持可動部528が折曲部525a、525bをその挟持面部529a、529bが互いに接近するよう移動させて、電極端子板21、22ごとシート状電池1Aを挟持する。その後、挟持可動部528はその挟持した状態のまま折曲部525a、525bを所定角度、例えば挟持面529a、529bが水平になるまで回転させる。これにより折曲部525a、525bの先端部524a、524bによりシート状電池1Aが折り曲げられる。 The pair of bent portions 525a, in a state where the sheet-like battery 1A during 525b runs through, the electrode terminal plate supply unit is close to the anode terminal plate 22 to the negative electrode layer 3 side of the sheet-like battery 1A, The positive electrode terminal plate 21 is brought close to the positive electrode layer 2 side. In this state, the sandwiching movable portion 528 moves the bent portions 525a and 525b so that the sandwiching surface portions 529a and 529b approach each other, and sandwiches the sheet-like battery 1A together with the electrode terminal plates 21 and 22. Thereafter, the sandwiching movable part 528 rotates the bent parts 525a and 525b in a sandwiched state at a predetermined angle, for example, until the sandwiching surfaces 529a and 529b are horizontal. Thereby, the sheet-like battery 1A is bent by the tip portions 524a and 524b of the bent portions 525a and 525b.

また、シート折畳機構部122Aは、シート状電池1Aが所定の距離進むごとに、折曲部525a、525bによりシート状電池1Aを折り曲げること、プレス部526a、526bにより押圧すること、及び、プレス部526a、526bの押圧と折曲部525a、525bによる挟持を解除してシート状電池1Aを所定の長さ繰り出すこと、を繰り返すことで、蛇腹状のシート状電池1Aを形成する。電極端子が挿入されたシート状電池1Aは、トレー101上に積み重ねられる。 Further, the sheet folding mechanism portion 122A is configured to bend the sheet-like battery 1A by the folding portions 525a and 525b, press the pressing portions 526a and 526b, and press each time the sheet-like battery 1A advances by a predetermined distance. By repeating the pressing of the portions 526a and 526b and the clamping by the bent portions 525a and 525b and feeding out the sheet-like battery 1A by a predetermined length, the bellows-like sheet-like battery 1A is formed. The sheet-like battery 1 </ b> A in which the electrode terminals are inserted is stacked on the tray 101.

[Electrode terminal supply / battery folding step]
When the sheet battery 1A is fed from the battery supply unit 51 to the electrode terminal supply / folding unit 55 to a predetermined position, the sheet folding mechanism unit 122A causes the electrode terminal plate supply unit to move the electrode terminal plates 21 and 22 to each other. While being supplied, it is bent using bending means such as the bent portions 525a and 525b and the press portions 526a and 526b. Since the detailed operation is as described above, the description thereof is omitted. Thereby, simultaneously with folding the sheet battery 1A, the positive electrode terminal plate 21 and the negative electrode terminal plate 22 can be arranged in the folded portion of the sheet battery 1A folded in a bellows shape. The folded sheet batteries 1A are stacked on the tray 101. The sheet battery 1 </ b> A bent a predetermined number of times is cut by the sheet cutting unit 121. The electrode terminal plate disposed on the lower surface of the bellows-shaped battery 1A may be disposed in advance at a predetermined position of the tray 101, or the electrode terminal plate disposed on the upper surface may be placed on the upper surface after the folding is completed.
