Pressurizing short-circuit inspection apparatus for detecting low-voltage defective pouch-type secondary battery cell

A pressurizing short-circuit inspection apparatus, comprising:

• compression plates arranged with a predetermined separation distance therebetween so that at least one secondary battery cell is insertable therebetween, the compression plates being movable along a first axis to adjust the separation distance;
• and
• a pressurizing short-circuit inspection assembly having a cell pressing unit configured to be pressable against a predetermined region of a body of the secondary battery cell and a power supply configured to be contactable with an electrode lead of the secondary battery cell to apply a test voltage, the pressurizing short-circuit inspection assembly being mounted to the compression plates to be movable along a second axis perpendicular to the first axis,
• wherein the cell pressing unit includes balls provided at at least one surface thereof to be pressable against the body of the secondary battery cell, and
• wherein the cell pressing unit and the power supply are provided to be moved together along the first axis.

• wherein the pressurizing short-circuit inspection assembly further includes a structure-reinforcing block unit configured to connect the cell pressing unit and the power supply into a single body, and
• wherein the structure-reinforcing block unit includes:
• an upper block configured to connect top portions of the cell pressing unit and the power supply and mounted to a top end of each compression plate to be slidable thereon;
• and
• a lower block configured to connect bottom portions of the cell pressing unit and the power supply and mounted to a bottom end of the compression plate to be slidable thereon.
