Abstract
Discussed is a bonding state inspection apparatus and a bonding state inspection method using the apparatus, and more particularly to a bonding state inspection apparatus including a transfer unit configured to transfer a battery module having a plurality of battery cells received therein, a thermal image inspection unit configured to scan an upper surface of the battery module, and a shear inspection unit configured to apply a shear force to a bonding ball formed at the battery module and a bonding state inspection method using the same.
Claims13
A bonding state inspection apparatus comprising:
- a transfer unit configured to transfer a battery module having a plurality of battery cells received therein;
- a thermal image inspection unit configured to scan an upper surface of the battery module;
- and
- a shear inspection unit configured to apply a shear force to a bonding ball formed at the battery module,
- wherein the shear inspection unit comprises:
- a moving shaft having a predetermined length;
- a body portion located under the moving shaft;
- an inspection tip provided at a lower surface of the body portion;
- and
- a displacement sensor provided at a side surface of the body portion,
- wherein the moving shaft is movable in a direction parallel to a transfer direction of the battery module and in a direction perpendicular to the transfer direction of the battery module,
- wherein both the transfer direction and the direction perpendicular to the transfer direction are parallel with the upper surface of the battery module, and
- wherein the transfer direction of the battery module is parallel to an extending direction of the transfer unit.
