Abstract

The present disclosure provides a coating method for suppressing variations in a coating amount, a coating apparatus and a method for manufacturing a component. A coating method is employed, which includes: discharging a coating needle adhering to an adhesive from a nozzle; separating the adhesive into the tip of the coating needle and the nozzle; and adhering the adhesive to a first member. A coating apparatus is employed, which includes: a nozzle which holds the adhesive; a coating needle which is discharged from the nozzle in a state where the adhesive is adhered to the tip; and a control unit which controls moving speed of the coating needle to separate the adhesive into the tip of the coating needle and the nozzle.

Claims4

Dependent claims

A coating method comprising:

discharging a coating needle with an adhesive attached as one lump from a tip to a lateral surface of the coating needle from a nozzle;
separating the one lump of adhesive into adhesive at the tip of the coating needle and adhesive at the lateral surface of the coating needle by further discharging the coating needle after the discharging and changing a moving speed of the coating needle;
and
making the adhesive at the tip of the coating needle adhere to a first member by further discharging the coating needle after the separating,
wherein the changing of the moving speed of the coating needle is not a temporary stop, but a reduction in speed to a speed slower than the moving speed of the coating needle immediately after the discharging, and after the separation, the speed of the coating needle is increased again.
