AI Technical Summary

Technical Problem

During the ultrasonic metal welding of lithium-ion batteries, the existing ultrasonic ear protection sheet is prone to sink due to the movement of the welding fixture, resulting in position deviation and poor welding.

Method used

A positioning tool for ultrasonic welding is designed, including the placement position, positioning structure and support structure on the cover plate. The placement position is a groove opened on the cover plate. The positioning structure avoids the offset of the ear protection sheet through the side positioning part, and the lifting structure prevents the ear protection sheet from sinking through the insertion tongue.

Benefits of technology

By setting up positioning ports, side positioning parts and lifting structures, the deviation and sinking of the extreme ear protection sheet are effectively avoided, the stability and quality of welding are improved, and the structure is simple and the production cost is low.
