[0002] The storage battery case is one of the core components of the storage battery, and its main function is to accommodate the electrode group, electrolyte and provide physical protection. Its structure needs to have corrosion resistance and is usually made of acid-resistant plastic or hard rubber to prevent the electrolyte from eroding.

[0003] In the prior art, the patent number is CN222890363U, and the name is a blanking device. The blanking device includes: a frame with an installation plane; a blanking component including a first die, a second die and a bracket. The first die and the bracket are both installed on the installation plane. The bracket includes a limiting plate.

The motor 27 drives the first rotating shaft 17 to rotate, and the first rotating shaft 17 drives the cylinder 14 to rotate, so that the workpiece on the surface of the support plate 19 rotates along with the first rotating shaft 17. The arc-shaped plate 4 plays a limiting role. When the workpiece falls off the surface of the support plate 19, it can slide through the arc-shaped plate 4 and fall from the blanking groove 5. When the support plate 19 rotates to the bottom of the arc-shaped plate 4, the U-shaped rod 33 is abutted by the abutting rod 16, so that the U-shaped rod 33 drives the vertical rod 29 to move in the round hole 28, so that the second spring 31 is stretched. After the vertical rod 29 moves out of the round hole 28, the air outlet hole 30 is exposed outside the round hole 28.
