9. The special fixture for grabbing square batteries in groups according to claim 8, wherein the first power source (6) is a one-way cylinder, the second power source (9) is a two-way cylinder, and the negative pressure generator (15) is a negative pressure pump.
10. A clamping method for grabbing prismatic cells in groups, characterized in that it is based on a special fixture according to claim 9, said method comprising:
step one, providing square batteries and a grabbing device with the special clamp of claim 9, and stacking the square batteries into a square battery pack (4);
step two, starting the first power source (6) and the second power source (9), and driving the first clamping plate (5) and the second clamping plate (10) to be away from each other, so that the clamping space of the special clamp is larger than the volume of the square battery pack (4);
moving the special fixture to be right above the square battery pack (4) through grabbing equipment, and then falling to wrap the square battery pack (4);
driving the first clamping plates (5) to approach each other through a first power source (6), so that the single square batteries in the square battery pack (4) are mutually folded and the square battery pack (4) is clamped in the length direction;
driving the second clamping plates (10) to approach each other through a second power source (9) so as to clamp the square battery pack (4) in the width direction, and starting a negative pressure generator (15) to draw gas from a negative pressure hole (13) through a negative pressure pipeline (14) so that the square battery pack (4) is adsorbed on the second clamping plates (10) under the action of atmospheric pressure;
sixthly, the square battery pack (4) is placed on a preset position through a special clamp controlled by grabbing equipment;
and step seven, repeating the step two to the step six until the square battery pack (4) is completely grabbed, and then closing the grabbing equipment.
