SYSTEM AND METHOD FOR CONTROLLING DRYING VARIATION BY USING NEAR-INFRARED LAMPS

The subject application provides a system and method for controlling a drying variation by using near-infrared (NIR) lamps. The system includes: first and second density measurement parts configured to measure first and second density data that is density of an electrode plate before and after drying, respectively; a drying quantity calculation part configured to calculate drying quantity data by processing the first density data and the second density data; and a lamp controller configured to control output energy of each of the NIR lamps based on an instruction signal received from the drying quantity calculation part. The drying quantity calculation part is configured to calculate a drying variation by comparing the first density data and the second density data and maintains a uniform drying state of the electrode plate by correcting the drying variation in real time.
