Application device for applying adhesive, and adhesive application method

An application method for applying an adhesive to an object, the application method being executed by an application device including a dispenser configured to discharge the adhesive, and the method comprising:

• controlling the dispenser, prior to applying the adhesive to a specified part of the object, to apply the adhesive to a second part of the object different from the specified part;
• calculating an application quantity of the adhesive applied to the second part of the object;
• determining whether the application quantity is within a specified range;
• in response to determining that the application quantity is not within the specified range, determining whether the application quantity is within a correction-enabled range;
• in response to determining that the application quantity is within the correction-enabled range at a first timing, determining a necessary correction amount by which to correct an application pressure used by the dispenser to discharge the adhesive, the necessary correction amount being determined based on (i) a necessary correction amount at a second timing at which the application quantity is determined to be within the correction-enabled range, and (ii) an interval between the first timing and the second timing, the second timing being prior to the first timing:
• correcting the application pressure at the first timing, based on the necessary correction amount;
• and
• controlling the dispenser to apply the adhesive to the specified part of the object using the application pressure corrected based on the necessary correction amount, in a case in which the application quantity is determined to be within the specified range,
• wherein the necessary correction amount at the first timing is greater than the necessary correction amount at the second timing when the interval is less than a specified time.
