Method And Device For Measuring Height Of Pouch Cup Portion Accommodating Electrode Assembly

Disclosed are a method and apparatus for measuring a height of a pouch cup portion that accommodates an electrode assembly, which can improve the quality of a pouch by minimizing measurement deviations between measurers to improve the reliability for the height measurement of the pouch cup portion. The method for measuring the height of the pouch cup portion is a method for measuring a height of a pouch cup portion of a pouch case for a secondary battery, the method including the steps of: (a) covering a cup portion support jig with a pouch; (b) positioning an upper fixing jig to expose a corner portion for measuring a height of the cup portion in a pouch upper surface covered on the cup portion support jig, and to cover a periphery of the exposed corner; (c)positioning a lower fixing jig at a pouch wing portion and a peripheral bottom portion of a lower corner portion corresponding to the corner portion to expose the periphery of the lower corner portion and cover other portions; and (d) measuring the cup portion height of the corner portion exposed by the upper fixing jig and the lower fixing jig through a 3D shape measurer.
