AI Technical Summary

Technical Problem

Existing technologies cannot guarantee the accuracy of battery positioning during the stacking of lithium batteries, and manual operation is time-consuming and labor-intensive, which can easily lead to wrinkles and cracks in the separators, increasing costs.

Method used

A stacking and positioning mechanism for soft-pack lithium batteries for new energy vehicles is adopted, including a stacking mechanism, an isolation mechanism, and a conveying mechanism. Through the cooperation of a spiral rod, an electric suction plate, and a limiting rod, the electrode sheets are accurately and orderly stacked and positioned, and the separators are automatically covered and flattened to prevent contact between the positive and negative electrodes and the separators from shifting.

Benefits of technology

This enables precise and orderly stacking of electrode sheets, avoiding separator wrinkles and cracks, reducing manual operation costs, and improving stacking quality and battery safety.
