AI Technical Summary
In the lithium battery stacking process, the separator is prone to folding and sticking due to gravity and friction during the tail roll, which leads to a decrease in cell quality and production efficiency.
Design a tail roll pressure roller mechanism with diaphragm flattening function. By blowing air to flatten the diaphragm during the tail roll process, the flattening airflow is blown towards the diaphragm through the gas passage to prevent it from folding and sticking.
It effectively prevents the separator from folding and sticking during the tail winding process, improving cell quality and production efficiency. Moreover, its compact structure does not require increasing the size of the equipment and can adapt to the production needs of products of different sizes.
