Device for measuring length of electrode plate

摘要

A system for measuring a length of an electrode plate includes a body on which an electrode plate roll formed by spirally winding the electrode plate is provided; a control device to which the body is combined; and a measuring device including a thickness measurement unit combined with the body and electrically connected to the control device to measure a spirally wound thickness of the electrode plate that is spirally wound on the electrode plate roll, and a diameter measurement unit to measure a diameter of a hollow portion of the electrode plate roll, wherein the control device receives a moving distance of the thickness measurement unit and a moving distance of the diameter measurement unit and calculates the length of the electrode plate of the electrode plate roll.

1. A system for measuring a length of an electrode plate, the system comprising:
a body on which an electrode plate roll formed by spirally winding the electrode plate is provided; a control device to which the body is combined; and a measuring device including:
a thickness measurement unit combined with the body and electrically connected to the control device to measure a spirally wound thickness of the electrode plate that is spirally wound on the electrode plate roll, anda diameter measurement unit to measure a diameter of a hollow portion of the electrode plate roll, wherein the control device receives a moving distance of the thickness measurement unit and a moving distance of the diameter measurement unit and calculates the length of the electrode plate of the electrode plate roll wherein: the thickness measurement unit moves in parallel with a second direction that is perpendicular to a central axis direction of the hollow portion of the electrode plate roll, and the diameter measurement unit moves in parallel with the second direction.
