Problems solved by technology

However, during the kneading and shaping process, metal debris will be generated on the end face of the ear position
If metal debris is not disposed of in time, the physical self-discharge of the battery cell will increase, and even enter the inside of the battery cell to cause a short circuit between the positive electrode and the negative electrode, or scatter into the device, resulting in cross-contamination

Abstract

The invention relates to a battery end surface shaping device, which includes: a kneading and flattening component for kneading and shaping the end surface of the battery cell; It has a first end surface and a second end surface opposite to each other along its own axial direction and an air suction passage that runs through the first end surface and the second end surface. On the first end face, the air outlet is arranged on the second end face. The electric core end surface shaping device of the present invention can realize the synchronous kneading and shaping process and the dust removal process, and can timely and efficiently pump out the metal debris produced on the end surface of the electric core while kneading and shaping the end surface of the electric core. Separate to ensure the cleanliness of the kneading and shaping station, thereby reducing the possibility of metal debris scattering freely or entering the inside of the battery cell.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a battery end face shaping device. Background technique [0002] With the development of science and technology and the transformation of the world's energy structure, sustainable energy is gradually replacing traditional fossil fuels and becoming the mainstream energy. For example, electric vehicles are gradually replacing traditional fuel vehicles. One of the central components in an electric vehicle is the battery. Batteries are used to power electric vehicles. Existing cylindrical batteries are also being used more and more widely. After the positive electrode sheet, negative electrode sheet and separator are wound to form a cell, the area of ​​the positive electrode sheet that is not coated with active material forms the tab end face of the positive electrode, while the area of ​​the negative electrode sheet that is not coated with active material forms the tab end face...
