Description

Technical Field

[0001] The utility model relates to the technical field of battery production technology, in particular to an ultrasonic secondary positioning device and an adapter sheet. Background Art

[0002] In the manufacturing process of lithium iron phosphate batteries, after hot pressing and testing, ultrasound is needed to connect the adapter to the A and B battery cells. Before ultrasonic welding, the adapter needs to be accurately positioned to ensure that the positioning between the battery cell and the adapter does not change during the welding process, and the welding position does not shift. Normally, the adapter uses a spring clip to feed the material and a vacuum suction cup to pick up the material. If the adapter is placed directly on the ring rail positioning fixture, the positioning accuracy of the adapter cannot be guaranteed, which is not conducive to subsequent welding.

[0003] In some related technologies, the secondary positioning of lithium batteries is carried out using a profiling fixture, and the profiling fixture has high requirements on the accuracy of loading during the positioning process. In addition, during the process of product upgrading, the size of the adapter changes, and the size of the profiling fixture must also change. Although the use of a profiling fixture for positioning can reduce certain costs, if the adapter is slightly tilted or the vacuum suction cup is installed abnormally, a large number of adapters will be deformed. When the adapter and the top cover are laser welded together, the weld mark will also be offset, causing the battery cell to be interrupted and produce defects. At the same time, the profiling fixture will wear out due to long-term use, increasing the replacement cost.

[0004] Therefore, how to prevent the adapter from being offset during welding and causing the battery cell to be disconnected is a technical problem that needs to be solved urgently in this field. Utility Model Content
