Description

Technical Field

[0001] This utility model relates to the field of power battery technology, and in particular to an electrode shaping device. Background Technology

[0002] In each step of the battery electrode production process, a shaping and alignment device is needed to align the electrode sheets.

This mechanism is mounted on the side plate of the conveyor frame, and its reference surface is abutted against one side of the electrode and aligned with the conveying direction of the roller. This utility model provides an electrode alignment reference mechanism on the side plate of the conveyor frame, offering a reference surface aligned with the conveying direction of the roller for the electrodes, thereby improving the accuracy and consistency of battery electrode conveying on the roller.

[0004] The utility model patent with announcement number CN 209786118U discloses a fixture for improving the alignment accuracy of battery electrode sheets. The fixture includes a fixture body with several layers passing through it. Each layer has a sliding elongated hole, which allows the layers to slide within the fixture body. This enables the rapid stacking and collection of positive and negative electrode sheets, thereby improving production efficiency.

[0005] In the current metal die-cutting process, the die-cut electrode sheets enter the electrode sheet receiving box through the feeding rod. Then, the electrode sheet shaping device adjusts and aligns the electrode sheets. Currently, the overall contact area between the electrode sheet shaping device and the electrode sheet is small, and the contact points are not singular. Therefore, collisions with the electrode sheets during the shaping process can lead to defects such as electrode sheet damage, foil leakage, and breakage. Utility Model Content
