Description

Technical Field

[0001] The utility model is applied to the technical field of batteries, and particularly relates to a battery pole core membrane separation device. Background Art

[0002] New energy vehicle power battery is a power source power material replacement battery, which can be used in a wide range of battery power materials vehicles. The battery is formed by stacking the positive electrode core, diaphragm, negative electrode core and diaphragm in sequence and then rolling them up. However, the battery also has a lifespan, so it is necessary to recycle the waste power batteries of new energy vehicles. At present, manual recycling is adopted. After the positive electrode core is manually separated, the negative electrode core will still be wrapped between the two diaphragms. It is necessary to manually tear out the two diaphragms again and take out the negative electrode core. This operation not only has certain safety hazards, but also has low efficiency. At present, there are only rewinding robots that can automatically rewind and release the positive electrode core. If an automatic film separation device that can release the negative electrode core from the double-layer diaphragm can be studied, it can not only improve production efficiency well, but also reduce the safety hazards of manual production.
