Background

In the production process of the soft package lithium battery, the positions of the positive electrode lug and the negative electrode lug of the battery core have certain deviation, so that the subsequent procedures of punching, bending and the like of the electrode lug can be influenced, and the qualification rate of the soft package lithium battery is reduced. In the prior art, the lithium ion battery adopting the battery cell carrier has the advantages of good cycle performance, wide working temperature range, high voltage platform, environmental friendliness and the like, is distinguished from a few new energy sources, and becomes one of the power supplies which are attracted by attention.

The existing mechanism for adjusting and aligning the lug has the problems of long aligning time, low efficiency and poor flexibility. Better adjust the alignment to battery utmost point ear to promote the whole mechanical automation level of battery production. There is utmost point ear positioner among the correlation technique, the device is at first fixed a position electric core through positioning mechanism, and the location push pedal promotes electric core and location base plate and supports and lean on to realize the location. However, the sizes of different battery cores have deviation, and when the positioning device is used for positioning, the positioning deviation is large due to error accumulation, so that the deviation correction precision is insufficient during subsequent deviation correction. The existing mechanism for adjusting and aligning the lug has the problems of long aligning time, low efficiency and poor flexibility.

In order to achieve the purpose, the technical scheme adopted by the invention is that the lug is lifted firstly, and when the lug of the battery cell reaches the upper part of the welding platform, the lug falls and is placed on the welding platform, so that the situation that the lug of the battery cell touches the welding platform in the moving process is avoided, and meanwhile, the lug aligning device is improved, and the position of the positive and negative lugs is more accurately adjusted, so that the preparation is made for the procedures of pre-shaping the lug, entering an insulating sheet and the like.
