The electric double layer capacitor cell 10 is a multilayer electric double layer capacitor cell. More specifically, the capacitor body is composed of a positive electrode body (positive electrode body) and a negative electrode body (negative electrode body) in a predetermined laminate by alternately stacking them with a separator interposed therebetween. The A positive electrode body and a negative electrode body are comprised in flat form from the collector electrode and the polarizable electrode (activated carbon electrode) formed in the both surfaces. These collector electrodes are made of a rectangular metal foil (aluminum foil), and a strip-like conductive portion (lead) is integrally formed on one side of a rectangular plane. The conductive parts have the same poles converged and joined to form a positive extraction electrode 12 and a negative extraction electrode 13.

  And in the periphery of the container part 11 formed from the resin film (for example, aluminum laminate) of the laminated structure containing a metal layer, a part of the positive extraction electrode 12 and the negative extraction electrode 13 is extracted, and three except one side. The sides are heat-sealed (heat sealed). More specifically, the container portion 11 can be opened at one side from which the positive extraction electrode 12 and the negative extraction electrode 13 protrude, and an electrolyte is injected into the inside through the opening to impregnate the electrolyte. When the processing is completed, the remaining one side is thermally welded (heat sealed) in a state where air and moisture are removed by a vacuum pump, and the electric double layer capacitor cell 10 is manufactured.

  Generally, the electric double layer capacitor cell 10 configured as described above is used as an electric double layer capacitor module in which a plurality of electric double layer capacitor cells 10 are connected in series because the withstand voltage is low. At this time, it is necessary to connect the positive lead electrode 12 of one electric double layer capacitor cell 10 and the negative lead electrode 13 of another electric double layer capacitor cell 10.

Further, the positive lead electrode 12 and the negative lead electrode 13 are processed to provide a rivet hole 14 for inserting a rivet. The order of the extraction electrode cutting step, the extraction electrode bending step, and the step of forming the rivet hole 14 in the extraction electrode can be arbitrary.

Here, in the bending process of the extraction electrode, the electric double layer capacitor cell 10 having two patterns shown in FIGS. 2A and 2B is prepared, and the cells are connected as shown in FIG. In addition, the electric double layer capacitor cell 10 having the pattern of FIG. 2A → the electric double layer capacitor cell 10 having the pattern of FIG. 2B → the electric double layer capacitor cell 10 having the pattern of FIG. 2A → FIG. The electric double layer capacitor cell 10 →. The number of electric double layer capacitor cells 10 to be connected when configuring the electric double layer capacitor module is arbitrary. As the previous stage of connecting the extraction electrode, the electric double layer capacitor cell 1 to be connected
The zeros are temporarily assembled together. At this time, the extraction electrodes are overlapped and temporarily connected so that the positions of the rivet holes 14 provided in the extraction electrodes of the adjacent electric double layer capacitor cells 10 coincide.

  FIG. 4 is a view for explaining a manufacturing process in the method for manufacturing a capacitor module according to the embodiment of the present invention, and shows a state in which a plurality of electric double layer capacitor cells 10 are collectively assembled and accommodated in a frame member 50. Yes. Although not shown in FIG. 4, the frame member 50 is provided with urging means for pressing the plurality of electric double layer capacitor cells 10 in the stacking direction.

In FIG. 5, 110 is a base member, 140 is a comb-tooth member, 160 is a mounting screw, 170 is a pressing fixing member, and 190 is a mounting screw. FIG. 5 shows only the capacitor module manufacturing jig 100 excluding the product to be manufactured. In the actual manufacturing of the capacitor module, a plurality of electric double layer capacitor cells 10 accommodated in the previous frame member 50 are illustrated. Is used while being assembled to such a capacitor module manufacturing jig 100.

  Hereinafter, each part which comprises the jig | tool 100 for capacitor module manufacture is demonstrated in detail. FIG. 6 is a perspective view of the base member 110 of the capacitor module manufacturing jig 100 according to the embodiment of the present invention.

  The base member 110 is provided with a base portion 111 for placing the plurality of electric double layer capacitor cells 10 accommodated in the frame member 50 on the bottom surface portion. The portion 112 is provided so as to stand up from the base portion 111. The top surface portion 113 of each side wall portion 112 is provided with a mounting screw hole 115 used for screwing the comb-tooth member 140, and the comb-tooth member 140 is formed by such mounting screw hole 115. 113 is removable. In the capacitor module manufacturing jig 100 according to the present embodiment, a total of eight comb-tooth members 140 are attached to the top surface portion 113 by two mounting screws 160 at the top surface portions 113 on both sides.

  In the jig 100 for manufacturing a capacitor module according to the present embodiment, aluminum is used as a main material for constituting the base member 110. This is because the capacitor module manufacturing jig 100 as a whole is configured to be lightweight, and the load on an automatic welding machine (not shown) for mounting the jig is reduced. The material used for the base member 110 is not limited to aluminum, and any metal material can be used.

  Next, the comb tooth member 140 constituting the capacitor module manufacturing jig 100 will be described in more detail. FIG. 7 is a perspective view of the comb member 140 of the capacitor module manufacturing jig 100 according to the embodiment of the present invention.

The comb-tooth member 140 includes an attachment base 141 that is directly mounted on the top surface portion 113 and a plurality (five in this embodiment) of comb-tooth portions 144 that extend from the attachment base 141. Slits with slight intervals are provided between the respective comb teeth 144. The interval between the slits is such that the extraction electrodes 12 and 13 of the electric double layer capacitor cell 10 can pass therethrough. The attachment base 141 is provided with an insertion hole 142 for inserting an attachment screw 160 used when the comb-tooth member 140 is screwed to the top surface portion 113.

  Each comb tooth portion 144 is provided with a screw hole 145. The screw hole 145 is used when the pressing and fixing member 170 is screwed. The screw hole 14 of the comb tooth portion 144 is also used as a margin space when riveting the extraction electrodes of the electric double layer capacitor cell 10 together. Since it is also used for such riveting, when the electric double layer capacitor cell 10 housed in the frame member 50 is attached to the capacitor module manufacturing jig 100 according to the embodiment of the present invention by the comb tooth member 140, The rivet hole 14 and the screw hole 14 of the extraction electrode 12 and the extraction electrode 13 of the electric double layer capacitor cell 10 have a layout that substantially matches.

  In the capacitor module manufacturing jig 100 according to the present embodiment, the comb-tooth member 140 is made of a metal material having excellent thermal conductivity such as copper. The comb-tooth portion 144 of the comb-tooth member 140 is used so as to support the extraction electrodes 12 and 13 of the electric double layer capacitor cell 10 from below. And it is assumed that the welding process of extraction electrodes is performed in the state where extraction electrodes 12 and 13 were supported by comb-tooth part 144. FIG. Since it is not preferable that the heat generated in such a welding process is conducted from the extraction electrode to the container part 11 side, in this embodiment, a metal material such as copper having excellent thermal conductivity is used for the comb-tooth member 140. It suppresses that the heat accompanying welding is conducted from the extraction electrode to the container part 11 side. Incidentally, aluminum is used as the material of the extraction electrodes 12 and 13. Accordingly, since the melting point of aluminum used for the extraction electrodes 12 and 13 is lower than the melting point of copper used for the comb-tooth member 140, the extraction electrodes 12 and 13 and the comb-tooth member 140 are not welded.

  Next, the pressing and fixing member 170 constituting the capacitor module manufacturing jig 100 will be described in more detail. FIG. 8 is a perspective view of the pressing and fixing member 170 of the capacitor module manufacturing jig 100 according to the embodiment of the present invention. The pressing and fixing member 170 is a member that presses and fixes the lead electrodes of the temporarily connected electric double layer capacitor cell 10 from above, and is branched from the main trunk 171 in a direction perpendicular to the main trunk 171 extending in the longitudinal direction. Thus, the branch portion 172 extends. Each branch portion 172 is provided with an insertion hole 175, and the pressing fixing member 170 is screwed into the screw hole 145 of the comb-tooth member 140 by the insertion hole 175. Further, a notch 173 is provided between the branch part 172 and the branch part 172, and when the pressing fixing member 170 is attached to the comb tooth member 140, the notch part 173 is temporarily assembled. The arrangement is such that the leading extraction electrode is exposed.

  In the capacitor module manufacturing jig 100 according to the present embodiment, such a pressing and fixing member 170 is made of a metal material having excellent thermal conductivity such as copper. The pressing and fixing member 170 is used so as to press and fix the extraction electrodes 12 and 13 of the electric double layer capacitor cell 10 from above. Then, it is assumed that the welding process between the extraction electrodes is performed in a state where the extraction electrodes 12 and 13 are pressed and fixed by the pressing and fixing member 170. Since it is not preferable that the heat generated in such a welding process is conducted from the extraction electrode to the container part 11 side, in this embodiment, a metal material such as copper having excellent thermal conductivity is used for the press fixing member 17, It suppresses that the heat accompanying welding is conducted from the extraction electrode to the container part 11 side.
