Shown in In the battery pack A, three cylindrical batteries 51 are arranged in parallel as unit cells, and electrodes 52 are connected by a conductive material 53 so that the unit cells 51 are connected in series. The battery pack A is housed and fixed by, for example, an exterior member 54 made of a heat-shrinkable tube, and is exposed to the outside as an electrode terminal 55 (in the figure, the position of the plus electrode 55a above the left row of the battery pack A and the position thereof). Except for the negative electrode 55b located below the right column of the battery pack 10), the battery pack A is covered almost integrally.

For example, while holding a plurality of unit cells side by side as shown in FIG. 5, it is necessary to bridge a conductive material between the electrodes and perform welding. Conventionally, as a welding jig for holding a unit cell group integrally during this welding work, each worker winds and fixes the outer periphery of each unit cell group with a binding tape on a work table of an assembled battery manufacturing line or the like. And a communication opening 61 for inserting and removing a unit cell in a so-called drop-in system, as shown in FIG. The box-shaped unit cell holder 60 formed as described above is used as a welding jig, and each unit cell is inserted and held therein.

すく、場合によっては素電池群の保持固定が不十分な余
り再固定作業の実施など溶接作業全体の進行を滞らせる
結果に繋がるおそれも十分にある。In the conventional method of holding and fixing a unit cell group with a binding tape, a predetermined binding tape is always consumed for each operation, so that the material cost included in the operation cost naturally increases. In addition, complicated and irrefutable manual work such as winding the tape while holding the unit cells is required for each worker, and both the working efficiency and the working accuracy are reduced to a low level. Inevitable. In addition, the work accuracy tends to fluctuate for each worker and for each work, and in some cases, the holding and fixing of the unit cells may be insufficient, and the progress of the entire welding work may be delayed, such as performing re-fixing work. There is enough.

間を要することもある。In the above-described method using the box-shaped cell holder as a welding jig, there is less possibility that the holding and fixing of the cell group as in the case of using the binding tape becomes uncertain. However, since this holder has no reversing movement function such as being capable of rotating, swinging, or horizontally moving while being fixed on a work table or the like, it is simply a “box”. Once inserted into the holder, even the welding work on the electrode surface facing the operator is extremely difficult due to the delicate alignment of the welding arm etc. of the welding equipment and the welding surface, etc. Sometimes it takes.

It has been inevitable that an increase in the number of complicated steps, such as facing the device or taking out a unit cell group from a holder that does not particularly have a take-out mechanism, replacing the top and bottom, and re-inserting and performing the same work, has been inevitable.

Not so many careless mistakes that mistakenly weld electrodes even to electrodes that do not need to be welded occur, and it is necessary to carry out correction work later, or the mistake itself is not noticed and the yield of the entire assembled battery production deteriorates. I was also invited.

As for the assembly man-hours, the comparative example 1 increased by 4.5 hours (approximately 23% increase) and the comparative example 2 increased by 3 hours (approximately 15% increase) from 19 hours of the present invention. In light of the current manufacturing situation where it is common to do this, there is no doubt that the greater the production, the greater the difference and the more it becomes impossible to overlook. Further, focusing on the defect occurrence rate, the occurrence rate is 1% in both comparative examples, whereas no defect occurrence is found in the present invention. Although the difference is 1%, it is usually very difficult for the manufacturing industry to achieve a defect rate of zero, and in the situation where efforts are being made daily to improve the defect rate, the defect rate may be zero. This is important in this case. In addition, the manufacturing costs including the man-hours and the defect occurrence rate as related factors naturally reflect the manufacturing costs (comparative examples 1 and 2 have higher costs of 5% and 3% compared to the present invention). It is shown.
