Abstract
An apparatus for inspecting a pouch sealing thickness, the apparatus including a first confocal sensor unit configured to measure a first thickness of one of a side sealing and a tab sealing of a pouch battery cell, a second confocal sensor unit configured to measure a second thickness of the side sealing and the tab sealing of the pouch battery cell, resulting in two measured thicknesses, a transport unit configured to transport the pouch battery cell to the first confocal sensor unit and the second confocal sensor unit, and a control unit configured to determine whether the pouch battery cell has a sealing defect from the two measured thicknesses.

An apparatus for inspecting a pouch sealing thickness, the apparatus comprising:
- a first confocal sensor unit configured to measure a first thickness of one of a side sealing and a tab sealing of a pouch battery cell;
- a second confocal sensor unit configured to measure a second thickness of the side sealing and the tab sealing of the pouch battery cell, resulting in two measured thicknesses;
- a transport unit configured to transport the pouch battery cell to the first confocal sensor unit and the second confocal sensor unit;
- and
- a control unit configured to determine whether the pouch battery cell has a sealing defect from the two measured thicknesses.
A method for inspecting a pouch sealing thickness, the method comprising:
- measuring a first thickness of one of a side sealing and a tab sealing of a pouch battery cell using a first confocal sensor unit;
- rotating the pouch battery cell 90°;
- and
- measuring a second thickness of the other of the side sealing and the tab sealing of the pouch battery cell using a second confocal sensor unit.
