The pole piece slitting machine is a key equipment on the lithium battery production line

The electrode slitting machine is an indispensable key equipment in the lithium battery production line, which is mainly used to accurately slitting the positive and negative electrodes that have been coated according to the specific width requirements, and winding and collecting them separately. The following is a detailed introduction to the pole piece slitting machine:

1. Equipment overview

Through advanced numerical control technology and image recognition technology, the pole piece slitting machine realizes the fast and accurate slitting of the pole piece. It is usually composed of parts such as feeding system, slitting system, positioning system and receiving system, among which the slitting system is the core component of the equipment.

2. The working principle

Feeding: The unslipped pole pieces are placed in the feeding system, and after positioning, the pole pieces are sent to the slitting system by the transmission device.

Slitting: The slitting system is mainly composed of a slicing knife and a pressure roller. The slicing knife cuts the pole piece into thin pieces of the specified width by rapid rotation, and the pressure roller ensures the accuracy and flatness of the cutting by pressurizing the pole piece.

Positioning: The positioning system uses image recognition technology to locate the slitted thin slice to ensure the accuracy of subsequent processing.

Receiving: The positioned flakes are received by the rewinding system and stacked in a unified manner or then wound for collection.
