<p><P>PROBLEM TO BE SOLVED: To provide a dipping inspection device for determining existence of a non-dipped part of electrolytic solution from intensity of a transmission wave by oscillating an ultrasonic wave to a battery cell, and to thereby contribute to shortening of a manufacturing process. <P>SOLUTION: In the dipping inspection device 1, an ultrasonic wave is irradiated from an ultrasonic generator 20 to the battery cell 2 filled with the electrolytic solution, and a transmission wave therefrom is detected by an ultrasonic detector 30, to thereby determine a dipping degree of the electrolytic solution relative to a positive electrode plate 2a, a negative electrode plate 2b, a separator 2c or the like which is a component of the battery cell 2. The ultrasonic generator 20 irradiates the ultrasonic wave from a tilted direction with respect to a direction orthogonal to the battery cell 2, and the ultrasonic detector 30 is arranged on a position facing to the ultrasonic generator 20 through the battery cell 2, coaxially with the irradiation direction D of the ultrasonic wave. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
