On-line detection mechanism of power battery short circuit prevention lamination stacking machine

The utility model relates to an on-line detection mechanism of a power battery short circuit prevention lamination stacking machine, which is applied to the manufacture of a power battery. In the process of lamination stacking, short circuit detection is automatically carried out once a lamination is stacked. The on-line detection mechanism is characterized in that an insulating plate is fixed on a lower plane of a pressure plate of the power battery short circuit prevention lamination stacking machine. Support plates are arranged at the lower parts of a positive lug and a negative lug of the lamination, two air cylinders are fixed on the support plates, an insulating sleeve is respectively fixed at the top part of a piston rod of each air cylinder, a conductive cap is respectively fixed at the upper part of each insulating sleeve, and the two conductive caps are respectively arranged at the lower part of the positive lug and the lower part of the negative lug and respectively connected with a lead-out wire.
