Description

Technical Field

[0001] The utility model relates to the technical field of soft-pack battery processing, in particular to a pole piece die-cutting device for a soft-pack battery. Background Art

[0002] Soft-pack lithium batteries are just liquid lithium-ion batteries covered with a polymer shell. They are structurally packaged with aluminum-plastic film. In the event of a safety hazard, the soft-pack battery will only bulge and crack. In the die-cutting production process of lithium-ion battery pole pieces, a die-cutting device is required. However, in the existing die-cutting device, when the pole piece material is die-cut, the pole piece material is easily offset, which will affect the die-cutting effect of the pole piece.

[0003] As in the prior art, the Chinese utility model with publication number: CN218776769U discloses a soft-pack battery pole piece die-cutting forming device. The utility model has a simple structure. In actual use, when the hydraulic cylinder drives the cutting platform to move downward, the clamping block will first contact the pole piece material. When the cutting platform continues to move downward, the clamping block can compress the spring. At the same time, the cutting die at the bottom of the cutting platform can slice the pole piece material, which can ensure that the pole piece material will not be offset during die-cutting, thereby ensuring the die-cutting effect of the pole piece material.

[0004] Through the above technology, it can be known that in the existing pole piece die-cutting device, there is no limiting anti-bias structure. When the pole piece material is die-cut, the pole piece material is prone to deviation, which will affect the die-cutting effect of the pole piece. Therefore, we need to propose a pole piece die-cutting device for soft-pack batteries. Utility Model Content
