1. An adhesive coating device for coating an inner wall surface of a hole of a workpiece provided with holes-with an adhesive, the device comprising:
a table that holds the workpiece;
a jet-type dispenser that applies the adhesive in a non-contact manner by forming microparticles from the adhesive in a liquid form and linearly and successively ejecting the microparticles from a nozzle;
a robot that causes a relative position of the nozzle of the dispenser to freely move with respect to the hole of the workpiece; and
a computer that controls the mechanism and causes the mechanism to automatically execute an operation of applying the adhesive, the operation including positioning of the workpiece, relative positioning of the nozzle with respect to the workpiece, and moving of the nozzle,
wherein two pieces of the dispenser are symmetrically provided in a direction perpendicular to the direction in which the holes are extending, the two pieces of the dispenser are disposed in an inclined form with respect to the direction perpendicular to the direction in which the holes are extending, the adhesive is ejected and applied in an oblique direction from the nozzle to the inner wall surface of the hole, an angle of the oblique direction is such an angle that the adhesive linearly ejected from the nozzle located outside the hole is able to be applied to the inner wall surface of the hole with a desired depth without interfering with an opening part of the hole, and application of the adhesive is alternately performed by the two pieces of the dispenser.
