【Technical field】

The invention relates to storage battery production equipment, in particular to a shaping mechanism for arranging pole groups during storage battery production.

【Background technique】

In the automatic production of storage batteries, it is necessary to connect the tabs of the positive and negative monomer pole groups by casting welding. The automatic wrapping machine puts the wrapped single electrode group into the casting and welding fixture and then clamps the casting and welding fixture, but the electrode group transferred from the material transfer device to the casting and welding fixture has deviations in the mutual positions of the plates. Therefore, it is necessary to align the polar groups.

In the traditional battery production process, the two processes of tab correction and shaping are all carried out manually. There are certain deficiencies in this kind of manual operation mode. The first is low work efficiency, and the second is unstable quality. The specific operation process is as follows: the lug inserting process, after the workers insert the assembled pole group into the mold box, hold a correction plate to press the pole group in place, and then put the correction plate into the pole group to fix the position; In the tab calibration process, another correction plate is used to correct the tabs, and finally the locking wrench of the mold box is locked by hand; in the tab shaping process, after the mold box is locked, the worker takes pliers to lock the outside of the pole group. The negative ear is reshaped. Because there are many operation steps, it takes a lot of time to complete it by one worker. In addition, manual correction and shaping can not guarantee the consistency of each action, which will lead to differences in casting and welding quality.
