The difference between the lower case 120 for the work B and the lower case 130 for the work C is that the sub-positioning pins 202 and the moving block 207 are moved because the length of the stack assembly 105 is different.
- the position of the battery unit 100 arranged on the pallet 200 is also different.
- the number of battery cells 103 of the stack assembly 105 used for the work C lower case 130 is 34. Accordingly, since it cannot be used in common with the positions of the sub-positioning pin 202 and the moving block 207 of the lower case 110 for the work A and the lower case 120 for the work B, it is necessary to change the setup.
- the stack assembly 105 is only elongated horizontally, and the shape of the end plate 101 used is the same.
- the number of battery cells 103 used in the stack assembly 105 used in the work A lower case 110 and the work B lower case 120 is 32, while the number of battery cells 103 used in the stack assembly 105 used in the work C lower case 130 is. Is 34. Therefore, the lower case 130 for the work C needs to be set larger than the lower case 110 for the work A.
- the auxiliary positioning pin 202 and the moving block 207 are replaced, and the main positioning pin positioning hole 131 and the auxiliary positioning pin positioning hole 132 provided in the workpiece C lower case 130.

- the main positioning pin 201 is fixed to the base 210, and the sub positioning pin 202 is held on the base 210 so as to be movable with respect to the main positioning pin 201. It is what is done.
- the position of the battery unit 100 is determined by inserting the main positioning pin 201 and the sub positioning pin 202 into the positioning hole 101a prepared in the end plate 101. Since the stack assembly 105 uses a plurality of battery cells 103 side by side, the size of the stack assembly 105 changes only in the direction in which the battery cells 103 are stacked. For this reason, by changing the position of the sub positioning pin 202 with respect to the main positioning pin 201, it becomes possible to deal with a plurality of types of battery units 100. Therefore, since it is possible to deal with a plurality of types of battery units 100 using one pallet 200, there is a cost merit.
- Applicant's production method requires that the battery unit 100 be randomly flowed on one line for the purpose of reducing the inventory as much as possible.
- Productivity is poor in lot productivity.
- productivity is deteriorated by about 4.5% when lot production is performed. Therefore, it is necessary that the pallet 200 can be used in common for a wide variety of products, and the common use of the pallet 200 by the method of the present invention can greatly contribute to the cost reduction of the battery unit 100.
- the main positioning pin 201, the auxiliary positioning pin 202, the seat pin 203, and the dowel relief hole pin 204 that are held in a detachable state from the pallet 200 are used for the workpiece A lower case 110 or the workpiece B. Since the lower case 120 or the lower case 130 for the workpiece C is received, the life of the pallet 200 can be extended. Since the main positioning pin 201, the sub positioning pin 202, the bearing surface pin 203, and the dowel relief hole pin 204 are made of highly wear-resistant members, it is possible to contribute to extending the life of the pallet 200.
- the main positioning pin 201 has a stepped shape including the tip portion 201a and the receiving seat 201b, the main positioning pin 201 also has a function of receiving the lower case 110 for the work A of the seat pin 203 and the like. Therefore, the installation space on the pallet 200 can be reduced.
- This structure is the same for the sub-positioning pin 202. By moving the sub-positioning pin 202 after changing the position, the receiving seat can also be moved, so that the trouble of changing the position can be omitted and the function can be avoided. For this reason, it can contribute to improving the production efficiency of the battery unit 100.
- the second embodiment has substantially the same configuration as the first embodiment, but the aspect of the setup change of the pallet 200 is slightly different, and this will be described below.
- FIG. 15 shows a perspective view of the pallet 200 of the second embodiment.
- the sub positioning pin 202 and the moving block 207 provided on the pallet 200 can be moved on the base 210.
- the dowel relief hole pin 204 provided on the moving block 207 can also be moved on the base 210.
- the configuration of the moving block 207 is the same as that of the first embodiment, and the moving block 207 is moved by setup change.
- the dowel escape hole pin 204 By making the dowel escape hole pin 204 movable, it becomes possible to deal with more types of battery units 100.
- the movement of the auxiliary positioning pin 202 and the dowel relief hole pin 204 can be received by the dowel relief hole pin 204 in the vicinity of the end plate 101 if the amount of movement is small. Not a big problem.
- a position where the lower case bends that is, a case where the battery unit 100 is not suitable for receiving by the dowel relief hole pin 204 provided in the pallet 200 may be considered. For this reason, there are cases where it is advantageous to make the dowel relief hole-attached pin 204 movable.
- the invention has been described according to the first embodiment and the second embodiment.
- the invention is not limited to the embodiment, and a part of the configuration without departing from the gist of the invention. It is also possible to implement by appropriately changing.
- the position change position with the sub-positioning pin 202 and the moving block 207 is set to 2 positions, but it is not hindered to set the position to 3 positions or more in order to correspond to many types.
- the position of the dowel relief hole-attached pin 204 can be changed but also the position of the seat pin 203 can be changed.
- the lead time increases when the labor for the setup change increases, it is preferable that they can be shared as much as possible.
- it does not prevent changing the illustrated material, dimension, etc. within the range of a design matter.
