Circular buffer grooves are also provided at the joint of the two right-angle sides of the right-angle through groove 131 to prevent damage when the right-angle vertex of the square battery electrode cooperates with the right-angle through groove 131 during installation, so that the right-angle sides of the four right-angles of the square battery electrode are limited and the right-angle vertices are protected. Then, the upper packaging material 22 and the lower packaging material 23 are respectively wrapped around the fixture 1 from the upper and lower ends to prevent collision with the fixture 1 during transportation and thus prevent collision with the stack of electrodes 112.

By setting the right-angle through groove 131 to further limit the fixture unit 11, the stack of electrodes 112 in the fixture unit 11 can be stably clamped between the four limit posts 13. When transporting the stack of electrodes 112, damage to the four corners of the stack of electrodes 112 is prevented. Then, the fixture 1 is placed inside the packaging material 2 to further protect the stack of electrodes 112. Finally, a vacuum bag 3 is sleeved outside the packaging material 2, and the inside of the vacuum bag 3 is evacuated to a vacuum through the vacuum hole 31. The air inside the fixture 1 is also evacuated to a vacuum through the ventilation hole 21, so as to keep the stack of electrodes 112 in a vacuum environment and prevent the stack of electrodes 112 from being oxidized, effectively solving the problems of poor protection performance for battery electrodes and easy oxidation of battery electrodes in the prior art.

At the same time, by providing the convex block 171 and the limiting groove 134, the cover plate 17 and the limiting post 13 can be limited and fixed, so that the cover plate 17 is more stably fixed on the top of the fixture 1, making the fixture 1 a whole, thereby improving the structural stability of the square battery pole piece transfer device.

[0051] Optionally, it further includes a locking bolt 18.
