METHOD AND APPARATUS FOR COATING

摘要

PROBLEM TO BE SOLVED: To provide a coating method by which the irregular coating of a coating surface area is suppressed even if a coating operation by different coating magnification is carried out using the same nozzle and to provide an apparatus for the nozzle. SOLUTION: The instructed coating magnification and the coating magnification in the practical coating operation are not to be different but they have to be similar to the utmost. Namely, a plurality of instructed coating magnifications are set for every nozzles 112 for material coating. A coating place to be an object for the material coating is segmented into a plurality of groups corresponding to the coating magnification. The instructed coating magnification most approximate to the coating magnification of each group of the plurality of the instructed coating magnification is used for recognition trial. The instructed coating magnification and the coating magnification in the coating operation become similar by setting a plurality of the instructed coating magnification respectively to the average value of the coating magnification of the coating object belonging to each group. In the case an instructed coating magnification is provided to each nozzle, the average value of the coating magnification for coating place to be the object is used as the instructed coating magnification.
