PASTE EVALUATION DEVICE, PASTE EVALUATION METHOD, AND METHOD FOR MANUFACTURING ELECTRODE PLATE

摘要

PROBLEM TO BE SOLVED: To provide a paste evaluation device and a paste evaluation method capable of checking a quality affecting the productivity of a coating step of paste in-line, and to provide a method for manufacturing electrode plates while performing the evaluation.

SOLUTION: The paste evaluation device according to the present invention includes: a paste supply path 2 extending from a paste supply section 1 to a coating machine (a paste supply destination) 3; an ultrasonic measuring section (a rectangle section) 6 provided at a mid-flow of the paste supply path 2, in which the cross section of the paste path is rectangular; and a control section (a determination section) 19. The ultrasonic measuring section 6 is a section for applying ultrasonic waves to the paste in the path in two directions of the short-side direction and the long-side direction of the rectangular cross section and measuring reflected waves or transmitted waves in the respective directions. The control section 19 determines the quality of the paste based on the two-directional measurement results by the ultrasonic measuring section 6.
