Summary of the Invention

Problems to be Solved by the Invention

[0005] A secondary battery including a plurality of single cells has a plurality of voltage detection terminals, and each voltage detection terminal is connected to each single cell. Further, the voltage detection terminals are arranged in alignment in one direction to form a row.

[0006] Multiple voltage detection terminals are inserted into insertion holes in a resin component, which is provided to facilitate connection to a voltage measuring device, and are fixed to the resin component. By connecting the wiring connector of the voltage measuring device to the resin component into which the multiple voltage detection terminals are inserted and fixed, the voltage of the stacked secondary battery can be easily measured.

[0007] In this case, if the voltage detection terminals are very thin and easily bent, or if the insertion holes in the resin parts are small enough to correspond to the voltage detection terminals, it may be difficult to insert the tips of multiple voltage detection terminals into the respective insertion holes in the resin parts. Therefore, even in such cases, it is advisable to align the tips of each voltage detection terminal to ensure that multiple voltage detection terminals can be properly inserted into the resin parts. Note that this problem is not limited to voltage detection terminals, but can occur with any terminal that requires position adjustment or alignment.

[0008] Therefore, in view of the above circumstances, the main purpose of this disclosure is to provide a terminal alignment jig capable of adjusting and aligning the tip of a terminal, and a method for inserting a terminal using the same. [Means for solving the problem]

[0010] Furthermore, this disclosure provides a method for inserting terminals into a resin component having insertion holes partitioned to correspond to the positions of each terminal, wherein the tips of multiple terminals arranged in one direction on a secondary battery are inserted into the resin component having insertion holes partitioned to correspond to the positions of each tip, and the method comprises: an alignment step of aligning the tips of multiple terminals arranged in one direction by using the terminal alignment jig and clamping them with a rod-shaped member; and an insertion step of inserting the tip of each terminal into each insertion hole while the multiple terminals are clamped with the rod-shaped member. [Effects of the Invention]

[0011] According to the terminal alignment jig of this disclosure, terminals can be properly aligned while adjusting the position of their tips.

[0012] According to the terminal insertion method of this disclosure, the tips of each terminal can be inserted into the respective insertion holes of the resin component while the tips of the terminals are aligned in the appropriate position, thus allowing the tips of each terminal to be easily inserted into the resin component.

Embodiments for Carrying Out the Invention

[0014] [Terminal Alignment Jig] The terminal alignment jig of the present disclosure is a terminal alignment jig for aligning the tips of a plurality of terminals arranged in one direction provided in a secondary battery. The terminal alignment jig includes at least one alignment member. The alignment member has at least two rod-shaped members extending in the length direction. At least one of the rod-shaped members has a comb shape with a plurality of cutouts on the surface. By sandwiching a plurality of terminals arranged in one direction with the rod-shaped members so that each terminal enters each cutout, the tips of the terminals are aligned.

[0015] Hereinafter, the terminal alignment jig of the present disclosure will be described using the terminal alignment jig 100 which is one embodiment.

[0016] The terminal alignment jig 100 is a jig for aligning the tips 111 of a plurality of voltage detection terminals 110 arranged in the stacking direction. The plurality of voltage detection terminals 110 arranged in the stacking direction are each connected to the positive electrode layer or the negative electrode layer of the laminated secondary battery 200.

[0017] First, the laminated secondary battery 200 to be used with the terminal alignment jig 100 will be described. The laminated secondary battery 200 is formed by laminating a plurality of single cells including a positive electrode layer, an electrolyte layer, and a negative electrode layer. Fig. 1 shows a state where the resin component 300 is inserted into the laminated secondary battery 200. Fig. 1 shows a part of one side surface 201 of the laminated secondary battery 200 taken out. Hereinafter, the x direction shown in Fig. 1 will be described as the width direction, the y direction as the length direction (the lamination direction of the laminated secondary battery 200), and the z direction as the thickness direction.

[0018] As shown in Fig. 1, the laminated secondary battery 200 has five rows of a plurality of voltage detection terminals 110 (terminal row 120) arranged in the lamination direction on one side surface 201. One end of each voltage detection terminal 110 protrudes to the outside of the laminated secondary battery 200, and the other end is arranged inside the laminated secondary battery 200 and is electrically connected to the positive electrode layer or the negative electrode layer.

[0019] In order to easily detect the voltage of the laminated secondary battery 200, the voltage detection terminals 110 are inserted into the resin component 300. The resin component 300 is an insulating resin component that assists in connecting the voltage detection terminals 110 and the voltage detection device, and has a plurality of insertion holes 310 partitioned corresponding to the positions of the tips 111 of the respective voltage detection terminals 110. Therefore, the tip 111 of each voltage detection terminal 110 is inserted into the corresponding insertion hole 310.

[0020] The type of stacked secondary battery 200 is not particularly limited, and it is sufficient to have multiple single cells in which a positive electrode layer, an electrolyte layer, and a negative electrode layer are stacked in that order. The electrolyte layer may consist of a separator and an electrolyte solution, or it may consist of a solid electrolyte. The materials for the positive electrode layer, electrolyte layer, and negative electrode layer may be appropriately selected from known materials depending on the purpose. The shape of the voltage detection terminal 110 is an elongated linear metal member. The cross-sectional shape of the voltage detection terminal 110 is not particularly limited. For example, it may be a polygonal shape such as a rectangle, or it may be circular or elliptical. Generally, a voltage detection terminal 110 having a rectangular cross-sectional shape is used. The terminal width of the voltage detection terminal 110 is not particularly limited, but for example it is in the range of 0.01 mm to 1 mm. The "terminal width" of the voltage detection terminal 110 means the length in the direction perpendicular to the thickness direction in its cross-section. Also, the voltage detection terminal 110 may be straight or substantially straight. "Approximately straight" means that the voltage detection terminal 110 is straight overall, and it is acceptable if a part of it is bent.

[0021] The material of the resin part 300 is not particularly limited as long as it is an insulating resin. For example, the material of the resin part 300 may be appropriately selected from thermoplastic resin, thermosetting resin, etc. The shape of the insertion hole 310 is not particularly limited as long as the voltage detection terminal 110 can be inserted and fixed in a predetermined position. For example, the insertion hole 310 may have the cross-sectional shape shown in Figure 2.

[0022] Figure 2 is a cross-sectional view in the width direction of one insertion hole 310, focusing on the portion on the stacked secondary battery 200 side. As shown in Figure 2, the insertion hole 310 is a through hole having an opening 310a on the side into which the voltage detection terminal 110 is inserted, and an opening 310b on the side into which the connector of the voltage measuring device is connected. On the opening 310a side of the insertion hole 310, a guide 311 is provided that narrows in the width and length directions from the opening 310a towards the back of the insertion hole 310 in order to facilitate the insertion of the voltage detection terminal 110. The back side of the guide 311 (opening 310b side) is connected to a through hole 312 of a predetermined length. The through hole 312 is approximately the same size as the inner diameter of the voltage detection terminal 110 and serves to fix the position of the voltage detection terminal 110 when it is inserted into the insertion hole 310. In other words, the voltage detection terminal 110 needs to be inserted into the elongated through hole 312 of the insertion hole 310.

[0023] Here, the clearance between the voltage detection terminal 110 and the insertion hole 310 of the resin part 300 is narrow, making it difficult to insert the voltage detection terminal 110 into the insertion hole 310 (through hole 312). As mentioned above, a guide 311 is sometimes provided on the opening 310a side of the insertion hole 310 to facilitate insertion of the voltage detection terminal 110 into the insertion hole 310 (through hole 312), but even so, the entrance to the through hole 312 is small, making it difficult to insert the voltage detection terminal 110 into the through hole 312. In addition, the voltage detection terminal 110 generally has a very thin and easily bent shape, so it may not be in the correct position when inserted into the resin part 300. Therefore, when inserting the voltage detection terminal 110 into the resin part 300, it is necessary to adjust the tip 111 of the voltage detection terminal 110 to the correct position. A terminal alignment jig 100 of one embodiment is used to solve these problems. The terminal alignment jig 100 will be described in detail below.

[0024] <Terminal alignment jig 100> Figure 3 shows a perspective view of the terminal alignment jig 100. Figure 4 shows the opening and closing operation of the terminal alignment jig 100. Figure 4(a) shows the open state of the terminal alignment jig 100 (each alignment member 10), and Figure 4(b) shows the closed state of the terminal alignment jig 100 (each alignment member 10). Figure 5 shows a plan view showing how the voltage detection terminal 110 is sandwiched using the three rod-shaped members 11 to 13. Here, as with Figure 1, the x direction in Figure 3 will be described as the width direction, the y direction as the length direction (lamination direction), and the z direction as the thickness direction. Also, for convenience, in Figure 3, viewing the terminal alignment jig 100 from the front side in the thickness direction (second plate-shaped member 22 side) is called a front view.

[0025] As shown in Figure 3, the terminal alignment jig 100 comprises five alignment members 10 and a movable member 20 for opening and closing each alignment member 10.

[0026] (Alignment member 10) The alignment members 10 are members for aligning each terminal row 120 and are positioned at the location corresponding to each terminal row 120. Since the stacked secondary battery 200 has 5 terminal rows 120, the terminal alignment jig 100 also has 5 alignment members 10. In this way, the number of alignment members 10 corresponds to the number of terminal rows 120 in the target stacked secondary battery 200.

[0027] As shown in Figure 3, the alignment member 10 has three rod-shaped members 11 to 13 that extend in the longitudinal direction, and the alignment member 10 opens and closes as the rod-shaped members 11 to 13 move in the width direction. The rod-shaped members 11 to 13 are rod-shaped members that are longer than the terminal row 120. Thus, the direction in which the rod-shaped members 11 to 13 extend (longitudinal direction) coincides with the direction in which the multiple voltage detection terminals 110 are aligned (stacking direction).

[0028] When the alignment member 10 is open, the rod-shaped members 11 to 13 are arranged alternately on one side in the width direction and from one side in the thickness direction to the other side. "From one side in the thickness direction to the other side" means, for example, in a front view, that the rod-shaped members 11 to 13 are arranged from the front side in the thickness direction to the back side. "Alternately on one side in the width direction" means, for example, in a front view, that if rod-shaped member 11 is positioned to the right of the alignment member 10, then rod-shaped member 12 is positioned to the left of the alignment member 10, and rod-shaped member 13 is positioned to the right of the alignment member 10. Thus, when the alignment member 10 is open, in a front view, the rod-shaped members 11 to 13 are arranged alternately on the left and right sides from the front side to the back side in the thickness direction. Also, the rod-shaped members 11 and 13 positioned on one side in the width direction are aligned in the thickness direction. In this way, when multiple rod-shaped members are arranged on one side or the other side in the width direction, the multiple rod-shaped members are aligned in the thickness direction.

[0029] Furthermore, when the alignment member 10 is in the open state, the rod-shaped members 11 and 13 located on one side and the rod-shaped member 12 located on the other side are arranged with a predetermined gap in the width direction. The predetermined gap should be such that a voltage detection terminal 110 can be placed between the rod-shaped members 11 and 13 located on one side and the rod-shaped member 12 located on the other side. The positions of the rod-shaped members 11 to 13 in the thickness direction are not particularly limited, but they may be arranged in positions where they do not overlap when viewed in the width direction. For example, as shown in Figure 5, the rod-shaped members 11 and 12 do not have opposing portions in the width direction, and the rod-shaped members 12 and 13 do not have opposing portions in the width direction. That is, the length in the thickness direction between the rod-shaped members 11 and 13 is longer than the length in the thickness direction of the rod-shaped member 12, and the position of the rod-shaped member 12 in the thickness direction is between the rod-shaped members 11 and 13 in the thickness direction.

[0030] As shown in Figure 4, the rod-shaped members 11 and 13 located on one side and the rod-shaped member 12 located on the other side are each movable in the width direction, thereby opening and closing the alignment member 10. By opening and closing the alignment member 10, the width direction position of the tips 111 of the multiple voltage detection terminals 110 arranged in the stacking method can be appropriately adjusted.

[0031] Next, we will explain how the tip of the terminal 110 is clamped using the rod-shaped members 11 to 13. As shown in Figure 5, when the voltage detection terminal 110 is clamped using the three rod-shaped members 11 to 13, the voltage detection terminal 110 is supported by two rod-shaped members 11 and 13, and the voltage detection terminal 110 can be clamped from the opposite side by rod-shaped member 12, so that the widthwise position of the tip 111 of the voltage detection terminal 110 can be appropriately adjusted.

[0032] Returning to Figure 3, the rod-shaped members 11 to 13 will be explained further. As shown in Figure 3, among the rod-shaped members 11 to 13, rod-shaped member 12 has a comb-like shape with multiple notches 12a on its surface. Each notch 12a is positioned to correspond to the tip 111 of each voltage detection terminal 110 of the target terminal row 120, and is formed in a row along the length direction with a predetermined interval between them. By sandwiching the terminal row 120 with the rod-shaped members 11 to 13 so that the tip 111 of each voltage detection terminal 110 fits into each notch 12a, the longitudinal position of the tip 111 of the voltage detection terminal 110 can be adjusted.

[0033] The notch 12a has an opening on the side facing the rod-shaped members 11 and 13 in the width direction, and is formed to narrow toward the opposite side. That is, the notch 12a has an opening 12b and a guide portion 12c formed to narrow toward the outside in the width direction from the opening 12b. The guide portion 12c may be provided on both sides in the length direction, or on only one side. In Figure 3, a trapezoidal notch 12a is used. Other shapes of the notch 12a include, for example, a triangular shape, a polygonal shape, a semicircular shape, a semielliptical shape, etc. With a notch 12a having such a shape, the voltage detection terminal 110 can be guided to the back of the notch 12a, so the longitudinal position of the tip 111 of the voltage detection terminal 110 can be adjusted more appropriately.

[0034] Figure 6 shows how the voltage detection terminal 110 fits into the notch 12a. Figure 6 is a front view of the terminal alignment jig 100, with Figure 6(a) showing the open state of each alignment member 10 and Figure 6(b) showing the closed state of each alignment member 10. As shown in Figure 6, when the voltage detection terminal 110 is sandwiched between the rod-shaped members 11-13, it enters through the opening 12b of the corresponding notch 12a and is guided to the back by the guide portion 12c, thereby adjusting its position in the longitudinal direction.

[0035] In this way, by sandwiching the voltage detection terminal 110 using the rod-shaped members 11 to 13, the widthwise and lengthwise position of the tip 111 of the voltage detection terminal 110 can be adjusted to an appropriate position. Furthermore, by adjusting the widthwise and lengthwise position of the tip 111 of the voltage detection terminal 110, the twisting of the voltage detection terminal 110 can also be corrected.

[0036] (Movable member 20) The movable member 20 is a member equipped with an opening and closing mechanism for the terminal alignment jig 100 (each alignment member 10), and is positioned on one side in the longitudinal direction of the alignment member 10. The movable member 20 has a first plate-shaped member 21 that holds the rod-shaped members 11 and 13, and a second plate-shaped member 22 that holds the rod-shaped member 12. Figure 7 shows a plan view of the terminal alignment jig 100. Figure 7(a) shows the terminal alignment jig 100 in the open state, and Figure 7(b) shows the terminal alignment jig 100 in the closed state.

[0037] The first plate-shaped member 21 comprises a plate-shaped portion 21a and a plurality of holding portions 21b. The plate-shaped portion 21a is the part that holds the holding portions 21b, and by moving the plate-shaped portion 21a in the width direction, each holding portion 21b can also be moved together with it. The holding portions 21b are the parts that hold the rod-shaped members 11 and 13, and are provided so as to protrude from the plate-shaped portion 21a on one side in the thickness direction (the bottom side of the paper in Figure 7). The position of each holding portion 21b is determined by the position of each rod-shaped member 11 and 13. In addition, the holding portions 21b have the role of restricting the movement of the second plate-shaped member 22 (Figure 7(b)).

[0038] The second plate-shaped member 22 comprises a plate-shaped portion 22a and a plurality of holding portions 22b. The plate-shaped portion 22a is the part that holds the holding portions 22b, and by moving the plate-shaped portion 22a in the width direction, each holding portion 22b can also be moved together. The holding portions 22b are the parts that hold the rod-shaped members 12 and are provided so as to protrude from the plate-shaped portion 22a on the other side in the thickness direction (the upper side of the paper in Figure 7). The position of each holding portion 22b is determined by the position of each rod-shaped member 12. In addition, the holding portions 22b have the role of restricting the movement of the first plate-shaped member 22 (Figure 7(b)).

[0039] As shown in Figure 7, the first plate-shaped member 21 and the second plate-shaped member 22 are arranged such that the plate-shaped portions 21a and 22a face each other in the thickness direction, and the holding portions 21b and 22b face each other in the width direction. The terminal alignment jig 100 (each alignment member 10) can be opened and closed by moving at least one of the first plate-shaped member 21 and the second plate-shaped member 22 in the width direction. Here, as described above, the holding portions 21b and 22b restrict the movement of the first plate-shaped member 21 and the second plate-shaped member 22 in the width direction, and the first plate-shaped member 21 and the second plate-shaped member 22 can move in the width direction only within the range in which the holding portions 21b and 22b are in contact. This prevents excessive load from being placed on the voltage detection terminal 110 when clamping, and allows the voltage detection terminal 110 to be properly clamped by the alignment member 10.

[0040] (Example of using terminal alignment jig 100 (method of inserting terminals)) Figure 8 shows how the terminal alignment jig 100 is used on a stacked secondary battery 200, and how the tips 111 of each voltage detection terminal 110 are inserted into the respective insertion holes 311 of the resin component 300 with the voltage detection terminals 110 aligned.

[0041] First, as shown in Figure 8(a), the terminal alignment jig 100 (open state) is inserted into the five rows of terminals 120 from one side in the length direction (the upper side of the paper in Figure 8), and each alignment member 10 is placed in each row of terminals 120. Specifically, the terminal rows 120 are placed between the rod-shaped members 11, 13 and the rod-shaped member 12. Next, as shown in Figure 8(b), each terminal row 120 is sandwiched between each alignment member 10, and the tips 111 of the voltage detection terminals 110 are aligned. Specifically, the tips 111 of the terminal rows 120 are aligned by sandwiching them between the rod-shaped members 11 to 13. Then, as shown in Figure 8(c), with each terminal row 120 sandwiched between the alignment members 10 (rod-shaped members 11 to 13), the tips 111 of each voltage detection terminal 110 are inserted into the respective insertion holes 310 of the resin part 300. In this way, by properly aligning the tip 111 of the voltage detection terminal 110 using the terminal alignment jig 100, the tip 111 can be easily inserted into the insertion hole 310 of the resin part 300.

[0042] (supplement) In one embodiment, the target was a stacked secondary battery 200, but the type of secondary battery that the terminal alignment jig of this disclosure can target is not limited to this. This is because the target secondary battery only needs to have multiple terminals (terminal rows) aligned in one direction.

[0043] In one embodiment, the direction in which the multiple terminals 110 of the stacked secondary battery 200 are aligned is defined as the stacking direction (length direction). However, the direction in which the terminal rows are aligned is not limited to this, and may be any direction. Also, in one embodiment, the multiple terminals 110 (terminal row 120) aligned in the stacking direction are arranged in the length direction. However, in the terminal alignment jig of this disclosure, the direction in which the terminal rows are aligned is not limited to this, and may be any direction.

[0044] In one embodiment, the object to be aligned is a voltage detection terminal 110, but the terminal alignment jig of this disclosure is not limited to this, and can be used for any type of terminal. The shape of the terminal can be linear or substantially linear as described above. For example, a tab terminal can be used.

[0045] In one embodiment, there were five alignment members 10, but the terminal alignment jig of this disclosure is not limited to this, and the number of alignment members may be at least one. This is because the number of alignment members can be appropriately set according to the number of terminal rows.

[0046] In one embodiment, the alignment member 10 had three rod-shaped members 11 to 13, but the terminal alignment jig of this disclosure is not limited to this, and the alignment member may have at least two rod-shaped members. This is because two rod-shaped members are sufficient to hold the terminals. However, from the viewpoint of adjusting the widthwise position of the terminal tip, it is preferable to have at least three rod-shaped members.

[0047] In one embodiment, both the rod-shaped members 11 and 13 located on one side in the width direction and the rod-shaped member 12 located on the other side were movable in the width direction. However, the terminal alignment jig of this disclosure is not limited to this, and it is sufficient if either one of the rod-shaped members located on one side in the width direction or the other side is movable. That is, in the terminal alignment jig of this disclosure, it is sufficient if at least one of the rod-shaped members located on one side in the width direction or the other side is movable in the width direction.

[0048] In one embodiment, among the rod-shaped members 11 to 13 of the alignment member 10, only the surface of the rod-shaped member 12 had a comb-tooth shape with multiple notches 12a. However, the terminal alignment jig of this disclosure is not limited to this, and multiple rod-shaped members of the alignment member may have a comb-tooth shape. That is, in the terminal alignment jig of this disclosure, it is sufficient that at least one of the rod-shaped members of the alignment member has a comb-tooth shape with multiple notches on its surface.

[0049] In one embodiment, the opening and closing of each alignment member 10 was performed using a predetermined movable mechanism provided on the movable member 20, but the movable mechanism applied to the terminal alignment jig of this disclosure is not limited to this. Any mechanism capable of opening and closing the alignment members is acceptable.

[0050] In one embodiment, the alignment member 10 and the movable member 20 are made of separate components, but the terminal alignment jig of this disclosure is not limited to this form. For example, the alignment member and the movable member may be formed as a single unit.

[0051] Based on the above, a terminal alignment jig of the present disclosure has been described using one embodiment. According to the terminal alignment jig of the present disclosure, terminals can be properly aligned while adjusting the position of their tip.

[0052] [How to insert the terminals] The terminal insertion method of the present disclosure is a terminal insertion method for inserting the tips of a plurality of terminals arranged in one direction provided on a secondary battery into a resin component having insertion holes partitioned according to the position of each tip, comprising: an alignment step of aligning the tips of the plurality of terminals arranged in one direction by using the terminal alignment jig and clamping them with the rod-shaped member; and an insertion step of inserting the tip of each terminal into each insertion hole while the plurality of terminals are clamped with the rod-shaped member.

[0053] A detailed explanation of the terminal insertion method described herein has been given above and will therefore be omitted here. For example, one embodiment of the terminal insertion method is illustrated in Figure 8.

[0054] According to the terminal insertion method of this disclosure, the tips of each terminal can be inserted into the respective insertion holes of the resin part while the tips of the terminals are aligned in the appropriate position, thus allowing the terminals to be easily inserted into the resin part.
