then, the flaring rod driving piece 211 drives the flaring rod sliding plate 212 to slide leftwards along the lifting plate assembly 24 until each flaring rod 213 is opposite to the opening of one aluminum-plastic film 210 below, then the liquid injection driving assembly 23 drives the lifting plate assembly 24 to descend, when the flaring rod 213 is inserted into the opening of the aluminum-plastic film 210 and is 2mm away from the battery cell, the descending is stopped, the flaring rod 213 is ensured to be inserted into the opening of the corresponding aluminum-plastic film 210 to finish flaring, at the moment, the vacuum generator does not extract vacuum to the suction nozzle 432, the suction nozzle 432 is ensured not to absorb the aluminum-plastic film 210, and the opening driving assembly 42 continues to synchronously drive the two groups of suction nozzle assemblies 43 to be mutually far away along the fixed plate 412, so as to reach the avoidance position;
after the flaring operation is completed, the liquid injection driving assembly 23 drives the lifting plate assembly 24 to rise to an initial position, and then the flaring rod driving piece 211 drives the flaring rod sliding plate 212 to slide rightward along the lifting plate assembly 24 to the initial position;
then, the injection needle driving piece 221 drives the injection needle sliding plate 222 to slide rightwards along the lifting plate assembly 24 until each injection needle 223 is opposite to the opening of one aluminum-plastic film 210 below, and then the injection driving assembly 23 drives the lifting plate assembly 24 to descend so as to ensure that the injection needle 223 is inserted into the opening of the corresponding aluminum-plastic film 210 to finish injection;
when the liquid injection operation is completed, the liquid injection driving assembly 23 drives the lifting plate assembly 24 to ascend to the initial position, and the liquid receiving driving assembly 31 drives the liquid receiving box 32 to move forwards to the liquid receiving position;
finally, the priming driving assembly 23 drives the priming needle slide plate 222 to slide leftwards along the lifter plate assembly 24 to the initial position.
