Description

Bond spray machine {ADHESIVE SPRAY MACHINE}

The present invention relates to a bond spray machine, and more particularly, to a bond spray machine implemented so as to uniformly apply a bond to the surface of an automobile part while rotating the automobile part.

In general, a bond is used when bonding two objects, for example, when bonding a shoe sole and a midsole, bonding a paper box, and the like.

When applying the conventional bond, the operator puts an appropriate amount of liquid bond on the brush and then applies it to the object to be bonded. It has been pointed out as a problem that the application of the bond is not efficient because it is necessary to perform the application while repeatedly repeating the operation of applying the bond to the brush from time to time.

On the other hand, the above-mentioned background art is technical information that the inventor possessed for the derivation of the present invention or acquired in the process of derivation of the present invention, and it cannot be said that it is necessarily a known technique disclosed to the general public before the filing of the present invention. .
