step five: the negative pressure vacuum suction component sucks the pressing plate to be gripped, the Z-axis servo screw rod module continues to ascend, the guide piece returns to the original position relatively to the descending direction, the spring component is fully stretched, and the pressing plate gripping is completed.
9. The utility model provides a battery cell assembly line, its characterized in that includes battery cell and gets welding clamp plate station and/or battery cell and put welding clamp plate station, still includes the battery cell utmost point ear clamp plate and snatchs mechanism of preceding claim 1 to 7, and the servo lead screw module of Z axle of battery cell utmost point ear clamp plate snatch mechanism passes through Z axle module mounting panel and connects the servo lead screw module of X axle, still includes the module installing support, X axle servo lead screw module install in on the module installing support carries out X axle and Z axial transplanting motion to battery cell utmost point ear clamp plate snatch mechanism, to battery cell gets welding clamp plate station and/or battery cell puts welding clamp plate station transplanting clamp plate.
