step two: on the basis of the first step, the Z-axis servo lead screw module continues to drive to descend, the negative pressure vacuum suction component cannot descend, the guide piece moves upwards along the Z axis relative to the pressing plate grabbing mechanism mounting piece, and the elastic piece is compressed;
step three: the guide piece moves upwards relative to the pressing plate grabbing mechanism mounting piece along the Z axis to the guide piece to trigger a second proximity switch, the second proximity switch transmits a trigger signal to the control system, the Z axis servo lead screw module stops descending, the clamping cylinder starts the grabbing action of the pressing plate clamping jaw, and the negative pressure vacuum sucking part synchronously sucks the pressing plate;
step four: the negative pressure vacuum suction part senses that the grabbing action is finished, the Z-axis servo lead screw module rises, the guide piece relatively descends, and the elastic piece stretches;
step five: the negative pressure vacuum suction part sucks the pressing plate to be grabbed, the Z-axis servo lead screw module continues to ascend, the guide piece returns downwards relatively, the spring assembly extends completely, and the grabbing of the pressing plate is completed.
10. The battery cell assembly production line is characterized by comprising a battery cell welding pressing plate taking station and/or a battery cell welding pressing plate placing station, and further comprising the battery cell tab pressing plate grabbing mechanism of any one of claims 1 to 8, wherein a Z-axis servo lead screw module of the battery cell tab pressing plate grabbing mechanism is connected with an X-axis servo lead screw module through a Z-axis module mounting plate, and further comprising a module mounting bracket, the X-axis servo lead screw module is mounted on the module mounting bracket, the battery cell tab pressing plate grabbing mechanism is subjected to transplanting movement in the X-axis direction and the Z-axis direction, and the battery cell welding pressing plate taking station and/or the battery cell welding pressing plate placing station is subjected to transplanting movement.
