  By the way, when manufacturing a battery pack using the battery assembly described above, there is a case where an operation for changing the posture of the battery assembly is required in a predetermined manufacturing process. As an example, from the posture in which the extending direction of the electrode terminals of the single battery in the battery assembly matches the vertical direction, the posture in which the extending direction of the electrode terminals of the single battery in the battery assembly matches the horizontal direction. In order to change the posture of the battery assembly, it may be necessary to rotate the battery assembly by about 90 °. However, as described above, since the battery assembly is constituted by a plurality of single batteries, the battery assembly is heavy and the operation of changing the posture is not easy.

  This invention is made | formed in view of such a situation, and it aims at providing the attitude | position change jig | tool which can change the attitude | position of a battery module easily.

  In order to solve the above problems, an attitude changing jig according to the present invention is an attitude changing jig for changing the attitude of a battery module, and includes a first wall member on which the battery module is placed, And a rotation mechanism that supports the first wall member so that the first wall member can be rotated with one end portion of the one wall member as a rotation axis.

  The posture changing jig includes a first wall member and a rotation mechanism that rotatably holds the first wall member. Therefore, when the battery module is placed on the first wall member, the attitude of the battery module can be easily changed by rotating the first wall member using the rotation mechanism.

  The posture changing jig according to the present invention further includes a second wall member provided at one end of the first wall member, the first wall member including a main surface on which the battery module is placed, And the second wall member protrudes from one end so as to extend along the direction from the back surface to the main surface, and the first wall member in the second wall member Spacers may be provided on the wall member side surface. In this case, when the first wall member is rotated, the battery module is supported on the second wall member in the changed posture. In particular, the battery module is supported on the second wall member by the spacer while being separated from the surface of the second wall member on the first wall member side. For this reason, for example, if another member is placed on the surface of the second wall member on the first wall member side, the separate member can be attached to the battery module so as to protrude from the battery module by the size of the spacer. It becomes possible.

  In the posture changing jig according to the present invention, the first wall member may be provided with a guide portion that regulates the position of the battery module. In this case, the position of the battery module is regulated by the guide portion. For this reason, when attaching another member to the battery module, alignment of the battery module and the separate member is facilitated.

  The posture changing jig according to the present invention may further include an impact absorbing member that absorbs an impact generated in the battery module when the first wall member is rotated. In this case, when the first wall member is rotated to change the posture of the battery module, it is possible to prevent the battery module from being damaged.

  ADVANTAGE OF THE INVENTION According to this invention, the attitude | position change jig | tool which can change the attitude | position of a battery module easily can be provided.

It is a perspective view of a posture change jig concerning this embodiment. It is the front view and side view of an attitude | position change jig | tool shown by FIG. It is a figure which shows a mode that the attitude | position of a battery module is changed using the attitude | position change jig | tool shown by FIG. It is typical sectional drawing along the IV-IV line of (c) of FIG.

  Hereinafter, an embodiment of a posture changing jig according to the present invention will be described in detail with reference to the drawings. In the description of the drawings, the same elements or corresponding elements are denoted by the same reference numerals, and redundant description is omitted.

  FIG. 1 is a perspective view of the posture changing jig according to the present embodiment. 2A is a front view of the posture changing jig shown in FIG. 1, and FIG. 2B is a side view of the posture changing jig shown in FIG. The posture changing jig 1 shown in FIGS. 1 and 2 is for changing the posture of the battery module M.

  The battery module M is configured by, for example, integrating a plurality of battery units U. The plurality of battery units U are fixed and integrated with each other by a pair of end plates (not shown) arranged on both sides in the predetermined direction, for example, in a state of being arranged in a predetermined direction. Each battery unit U has a battery cell, and the battery cell is, for example, a rectangular nonaqueous electrolyte secondary battery, and a positive electrode terminal and a negative electrode terminal protrude from the same surface in the same direction.

  The posture changing jig 1 includes a rectangular plate-shaped support base 10, a holder 20 that holds the battery module M, and a rotation mechanism 30 that rotatably supports the holder 20 on the support base 10. . The support base 10 includes a plurality of columnar spacers 11 and spacers 12 provided on the surface on the holder 20 side.

  The holder 20 is a member that holds the battery module M, and is formed in a substantially U shape in the present embodiment. More specifically, the holder 20 protrudes in the thickness direction of the first wall member 21 from the rectangular wall-shaped first wall member 21 and the one end portion 21 c in the short direction of the first wall member 21. The rectangular wall-shaped second wall member 22 and the second wall member 22 in the thickness direction of the second wall member 22 from the other end 22f opposite to the one end 21c in the short direction of the second wall member 22, and It consists of a rectangular plate-shaped third wall member 23 protruding in the same direction as the extending direction of the first wall member 21.

  The first wall member 21 includes a main surface 21a and a back surface 21b opposite to the main surface 21a. The battery module M is placed on the main surface 21 a of the first wall member 21. A through hole extending in the longitudinal direction of the first wall member 21 is formed in one end portion 21c in the short direction of the first wall member 21 (an end portion on the second wall member 22 side in the first wall member 21). A shaft that functions as a rotation axis A, which will be described later, is provided in the through hole. A pair of gripping members 24 that are gripped when the first wall member 21 is rotated about the one end 21c as the rotation axis A are attached to the other end 21d in the short direction of the first wall member 21. . The one end portion 21c and the other end portion 21d in the short direction of the first wall member 21 are, for example, a pair of long side portions that define a rectangular shape of the first wall member 21.

  A rectangular recess 21e in which the battery module M is disposed is formed on the main surface 21a. The recess 21e is open to the one end 21c in the short direction and the other end 21d in the short direction of the first wall member 21. In other words, the recess 21e is formed by a pair of edge portions 21f.

  The pair of edge portions 21f function as guide portions that regulate the position of the battery module M on the first wall member 21 (main surface 21a). The guide portion (edge portion 21f) is a stripe-shaped convex portion extending from one end portion 21c in the short direction of the first wall member 21 toward the other end portion 21d in the short direction, and is long in the longitudinal direction. This is slightly larger than the short direction of the battery module M (the direction in which the electrode terminals are arranged in one battery unit U of the battery units U of the battery module M). The parallel arrangement direction of the battery units U in the battery module M is the longitudinal direction of the battery module M, and the direction perpendicular to the longitudinal direction and the short direction of the battery module M in the battery module M is the height direction of the battery module M. Will be described below.

  The second wall member 22 intersects with the widest surface (the main surface 21a and the back surface 21b) of the first wall member 21 (the thickness direction of the first wall member, the direction from the back surface 21b toward the main surface 21a). ) Projecting from one end portion 21c of the first wall member 21 in the short direction. Therefore, the second wall member 22 and the first wall member 21 form an angle of about 90 °, for example. Therefore, when the first wall member 21 is rotated about 90 ° to change the posture of the battery module M from the first posture to the second posture, the battery module M is placed on the second wall member 22. (Supported).

  The second wall member 22 is connected to one end 21c in the short direction of the first wall member 21 at one end 22e in the short direction. Further, a third wall member 23 is connected to the other end portion 22 f in the short direction of the second wall member 22. The one end 22e and the other end 22f in the short direction of the second wall member 22 are, for example, a pair of long side portions that define a rectangular shape of the second wall member 22.

  A spacer 22b is provided on the main surface 22c of the second wall member 22 (the surface on the first wall member 21 side (that is, the battery module M side of the widest surface of the second wall member 22)). ing. More specifically, the spacer 22 b has, for example, a rectangular flat plate shape, and is provided at the approximate center of the main surface 22 c of the second wall member 22. As an example, the spacer 22 b is formed integrally with the second wall member 22. The spacer 22b contacts the battery module M in a state where the battery module M is held by the holder 20. The spacer 22 b supports the battery module M in a state of being separated from the main surface 22 c of the second wall member 22.

  The length L22 in the longitudinal direction of the second wall member 22 is substantially the same as the length L21 in the longitudinal direction of the first wall member 21, and is longer than the length LM in the longitudinal direction of the battery module M. The length H22 in the short direction of the second wall member 22 is substantially the same as the length HM in the height direction of the battery module M (or longer than the length HM in the height direction).

  The third wall member 23 extends from the second wall member 22 so as to extend in a direction substantially parallel to the first wall member 21 (that is, a direction intersecting the main surface 22c of the second wall member 22). It protrudes from the other end 22f in the short direction. Therefore, the second wall member 22 and the third wall member 23 form an angle of about 90 °, for example. As described above, the third wall member 23 is connected to the other end 22f in the short direction of the second wall member 22 at one end 23a in the short direction.

  The length W23 in the short direction of the third wall member 23 is shorter than the length W21 in the short direction of the first wall member 21 and the length WM in the short direction of the battery module M. Therefore, when viewed from the direction from the back surface 21 b of the first wall member 21 to the main surface 21 a, the battery module M can be partially exposed from the third wall member 23.

  The rotation mechanism 30 includes a shaft (not shown) as the rotation axis A and a pair of bearing portions 31. As described above, the rotation axis A is set to the one end portion 21c of the first wall member 21 in the short direction. More specifically, the rotation axis A is configured by inserting a shaft through a through hole of one end portion 21 c in the short direction of the first wall member 21.

  The pair of bearing portions 31 support both ends of the shaft in the axial direction while being fixed to the support base 10. The bearing portion 31 can support the shaft via, for example, a bearing (not shown). As described above, the rotation mechanism 30 can rotate the first wall member 21 (holding tool 20) about the shaft (that is, the one end portion 21c in the short direction of the first wall member 21) as the rotation axis A. The first wall member 21 (holding tool 20) is supported on the support base 10.

  The posture changing jig 1 further includes a damper (impact absorbing member) 40. For example, the damper 40 has one end fixed to the support base 10 and the other end fixed to the second wall member 22 of the holder 20. The damper 40 absorbs an impact generated in the battery module M when the first wall member 21 (holding tool 20) is rotated.

  FIG. 3 is a diagram showing how the posture of the battery module is changed using the posture changing jig shown in FIGS. The work for changing the attitude of the battery module M shown in FIG. 3 is performed, for example, by attaching a bracket B (see FIG. 4) for fixing the battery module M to the casing of the battery pack on the end plate of the battery module M. This is a work that occurs.

  As shown in (a) of FIG. 3, here, first, the posture changing jig 1 is set to a first state in which the first wall member 21 of the holder 20 is substantially parallel to the support base 10. On the other hand, the battery module M has a first posture in which the height direction of the battery module M coincides with the vertical direction. In that state, the battery module M is connected to the first wall member 21 and the third wall from the U-shaped opening portion side of the holder 20 (that is, from the other end portion 21d side in the short direction of the first wall member 21). The slide is inserted into the area between the wall member 23 and the wall member 23. At this time, the battery module M is brought into contact with the spacer 22b.

  Thereby, the battery module M is placed on the main surface 21 a of the first wall member 21. At that time, the battery module M is guided by the guide portion (edge portion 21f) of the first wall member 21 while maintaining the first posture. For this reason, the position of the battery module M in the longitudinal direction is regulated by the guide portion of the first wall member 21.

  Subsequently, as shown in FIG. 3B, for example, the holding member 24 is held and the other end portion 21d in the short direction of the first wall member 21 is lifted to hold the shaft with the shaft as the rotation axis. 20 (first wall member 21) and the battery module M are rotated. And the holder 20 is rotated until the 2nd wall member 22 contacts the spacer 12 provided on the support stand 10, as FIG.3 (c) shows. By rotating the holder 20 in this manner, the posture changing jig 1 has the first wall member 21 substantially orthogonal to the support base 10 and the second wall member 22 substantially parallel to the support base 10. This is the second state.

  At the same time, the posture of the battery module M is changed to the second posture in which the height direction of the battery module M is substantially parallel to the support base 10. At this time, the battery module M is supported by being separated from the main surface 22c of the second wall member 22 by the spacer 22b. At this time, the battery module M is restricted from moving in the height direction by the third wall member 23 and is held at a predetermined position. Thereby, the attitude | position of the battery module M after a change is maintained.

  FIG. 4 is a schematic cross-sectional view taken along line IV-IV in FIG. When the bracket B is attached to the battery module M, for example, the bottom surface Bs of the bracket B is protruded from the side surface of the battery module M (surface facing the housing in the battery unit U) Ms. It is desirable to form a space defined by the side surface Ms and the pair of brackets B. This is because, for example, the space is used as a space for disposing the heat dissipation sheet.

  Here, as shown in FIG. 4, the battery module M in the second posture is separated from the main surface 22 c of the second wall member 22 by the spacer 22 b on the second wall member 22. It is supported. For this reason, if the bracket B is arranged on the battery module M while the bottom surface Bs of the bracket B is in contact with the main surface 22c of the second wall member 22, the bottom surface Bs of the bracket B is equivalent to the thickness T22 of the spacer 22b. The battery module M protrudes from the side surface Ms.

  Therefore, if the bracket B is attached to the battery module M in this state, the space for disposing the heat dissipation sheet on the side surface Ms of the battery module M can be formed. Therefore, it is desirable that the thickness T22 of the spacer 22b is set to be approximately the thickness of the heat dissipating sheet disposed on the side surface Ms of the battery module M.

  As described above, the posture changing jig 1 according to the present embodiment includes the first wall member 21 and the rotation mechanism 30 that rotatably holds the first wall member 21. Therefore, when the battery module M is placed on the first wall member 21 and the first wall member 21 is rotated using the rotation mechanism 30, the attitude of the battery module M can be easily changed. .

  Further, in the posture changing jig 1 according to the present embodiment, the first wall member 21 is provided with a guide portion (edge portion 21f) that defines the position of the battery module M. For this reason, the position of the battery module M is regulated. For this reason, when the bracket B is attached to the battery module M in the second posture, the battery module M and the bracket B can be easily aligned.

  The posture changing jig 1 according to the present embodiment further includes a second wall member 22 protruding from the one end 21c so as to extend in the intersecting direction with the first wall member 21. A spacer 22b is provided on the main surface 22c of the second wall member 22 on the first wall member 21 side. For this reason, as described above, when the first wall member 21 is rotated, the battery module M is supported on the second wall member 22 in the changed posture.

  In particular, the battery module M is supported on the second wall member 22 in a state of being separated from the main surface 22c of the second wall member 22 by the spacer 22b. Therefore, as described above, when the bracket B is placed on the main surface 22c of the second wall member 22, the bracket B is attached to the battery module M so as to protrude from the battery module M by the size of the spacer 22b. It becomes possible.

  In addition, the posture changing jig 1 according to the present embodiment further includes a damper 40 for absorbing an impact generated in the battery module M when the first wall member 21 is rotated. For this reason, when rotating the 1st wall member 21 and changing the attitude | position of the battery module M, it is suppressed that malfunctions, such as a damage, arise in the battery module M.

  Furthermore, in the posture changing jig 1 according to the present embodiment, a plurality of columnar spacers 11 and 12 are provided for the support base 10. The first wall member 21 of the holder 20 is supported by the support base 10 via the spacer 11, and the second wall member 22 is supported by the plate-like support base 10 via the spacer 12. That is, in the posture changing jig 1, since the plate-like members are not directly in contact with each other and supported, it is possible to suppress an accident such as a finger being caught between the members during the work.

  The above embodiment describes one embodiment of the posture changing jig according to the present invention. Therefore, the posture changing jig according to the present invention is not limited to the posture changing jig 1 described above. The posture changing jig according to the present invention can be obtained by arbitrarily changing the posture changing jig 1 described above without changing the gist of each claim.

  For example, in the posture changing jig 1, a stripe extending from the other end portion 21d of the first wall member 21 to the one end portion 21c as a guide portion for regulating the position of the battery module M on the first wall member 21. A convex portion (edge portion 21f) was used. However, the guide part that regulates the position of the battery module M may be realized by forming a plurality of columnar protrusions on the main surface 21a, or may be in any form.

  Further, the spacer 22b on the second wall member 22 is not limited to a rectangular plate shape. The spacer 22b can be in any mode capable of supporting the battery module M on the second wall member 22 in a state of being separated from the main surface 22c of the second wall member 22. For example, the spacer 22 b is not limited to a plate shape, and may be configured by forming a plurality of columnar protrusions on the main surface 22 c of the second wall member 22.

  Moreover, in the said embodiment, the height direction of the battery module M becomes substantially parallel to the support stand 10 from the 1st attitude | position where the height direction of the battery module M corresponds to a perpendicular direction in the attitude | position of the battery module M. Although the second posture (for example, coincides with the horizontal direction) has been changed, the reverse change can be easily performed as required.

  Therefore, the posture changing jig 1 causes the battery module M to move when the first wall member 21 (holding tool 20) is rotated so as to change the posture of the battery module M from the second posture to the first posture. Another damper may be further provided to absorb the generated impact.

  Moreover, as an impact-absorbing member for absorbing the impact which arises in the battery module M, it is not limited to a damper, For example, you may use arbitrary elastic members.

  Furthermore, although the rotation mechanism 30 is configured to include a shaft penetrating the one end portion 21c in the short direction of the first wall member 21 and a bearing portion 31 that supports the shaft, the rotation mechanism 30 includes, for example, a shaft. It does not have to be. In this case, for example, a configuration may be employed in which protrusions are provided at both ends in the longitudinal direction of the first wall member in the short direction 21c, and the pair of protrusions are supported by the bearing portion 31. .
