Thus, when the battery cell accommodating tray 530 needs to be transferred from the tray descending plate 522 to the tray lifting plate 512, the battery cell accommodating tray 530 may be stuck, so that the battery cell accommodating tray 530 may not be smoothly transferred. In order to better solve the technical problem, the battery cell blanking system 500 further includes a tray jacking device. The charging tray jacking device comprises a jacking cylinder and a jacking plate, and the jacking cylinder drives the jacking plate to stretch and retract in a reciprocating mode along the vertical direction. Like this, when needs transfer charging tray decline board 522 to charging tray lift plate 512 on, at first, jacking cylinder drive jacking board is ejecting along vertical direction for electric core accepts charging tray 530 and rises a height, and then, electric core accepts charging tray 530 is stirred to full charging tray backward flow toggle device 550, thereby makes the transfer that electric core accepts charging tray 530 can be smooth and easy.
According to the full-automatic liquid injection packaging machine 10, the battery cell feeding assembly line 100, the battery cell transmission system 200, the battery cell discharging assembly line 300, the battery cell liquid injection packaging system 400 and the battery cell discharging system 500 are arranged, so that the battery cell feeding, liquid injection, vacuumizing, packaging and discharging processing is realized, and the mechanical automation level of battery cell production is improved.
