APPARATUS FOR COATING ADHESIVE

摘要

PURPOSE:To make it possible to surely adhere electronic parts while prescribing the adhesion amount of an adhesive to a predetermined amount, by providing a convexed projection to the leading end of a coating pin for applying an adhesive to a printed circuit board. CONSTITUTION:A coating pin 12a is lowered in the direction shown by an arrow A and rise after adhering the adhesive 13 on an adhesive supply apparatus 3. At this time, the surface tension of the adhesive 13 acts on a projection 15 to make the amount of the adhesive 13 constant. When the adhesive 13 is applied to a printed circuit board in this state and electronic parts is transferred to said board to be adhered thereto, electronic parts can be stably mounted on the board to which a required amount of the adhesive 13 is constantly applied in such a state that the adhesive is slightly protruded or is not quite protruded.
