At the same time, the positioning head 334 falls and abuts against the top of the battery 50 to position the battery 50. At this time, the battery 50 rotates inside the limiting groove 22A until the tab and the sensing component 32 on the inclined part 3342 of the positioning head 334 complete the sensing, that is, the correction of the battery tab position is completed. Finally, the positioning device 30 and the correction device 40 are reset to the initial position to prepare for the next correction.
