Electrode Tab Guide Structure for Lateral Shift-Free Fusion

A guide part is introduced as an intermediary component between the tab transferring part and the electrode plate. The guide part includes guide grooves that receive and constrain the battery tab during transfer, preventing lateral displacement. This intermediary structure ensures the battery tab maintains correct positioning throughout the transfer process, resolving the contradiction between achieving transfer accuracy and preventing defects.

The patent replaces reliance on purely mechanical holding methods with a guided mechanical constraint system. Instead of depending solely on the holding force of the tab transferring part, the system uses the guide grooves to provide passive mechanical constraint that actively prevents lateral movement during transfer, thereby improving both transfer accuracy and reducing defect rates.

The tab-feeding device is segmented into distinct functional components: the tab transferring part and the guide part. The guide part is further segmented into multiple guide grooves that can be independently configured. This segmentation allows the positioning function to be separated from the transfer function, enabling accurate positioning without requiring complete redesign of the entire transfer mechanism, thus managing device complexity while improving positioning accuracy.

The guide part serves as an intermediary structure that adds positioning capability without fundamentally altering the core transfer mechanism. By introducing this intermediate guiding component rather than redesigning the entire transfer system, the patent achieves improved positioning accuracy while minimizing the increase in overall device complexity.
