AI Technical Summary

Technical Problem

During the production process of lithium-ion batteries, the width and size of the pole sheets become deteriorated after slicing, making it difficult to detect width problems in a timely manner.

Method used

A pole sheet width measuring device is designed, including a moving mechanism, a driving unit, a distance measuring unit and a control unit. The moving mechanism drives the distance measuring unit to move in the pole sheet width direction, and uses the distance measuring unit to identify the distance between the edges on both sides of the pole sheet to realize the detection of the pole sheet width.

Benefits of technology

The accurate detection of the width of the slitting pole sheet is achieved, and the problem of deterioration of width and dimensions can be detected in a timely manner, improving the quality control of the production process.
