Proposed is an automatic spray apparatus including an airbrush and mask transfer mechanism, the apparatus including an airbrush for spraying liquid through a nozzle by using air supplied thereto, an airbrush transfer unit capable of adjusting a relative distance from the airbrush to a liquid spray target while supporting the airbrush, a mask having a hole formed in a shape in which the liquid is applied on a surface of the liquid spray target, and a mask transfer unit installed between the nozzle of the airbrush and the liquid spray target while supporting the mask, wherein the airbrush transfer unit includes a trigger actuator capable of operating a trigger that controls the spraying of the liquid contained in a part of the airbrush. The automatic spray apparatus can be implemented at a relatively low cost to be used when manufacturing an MEA having a small area.

A cleaning device for atomizing and spraying liquid in two-phase flow comprising a nozzle provided with multiple liquid bypass pipelines each having liquid guiding outlets inclined at a predetermined angle and an exhaust mesh plate having vertical gas guiding outlets, which makes the high speed liquid flow and high speed gas flow sprayed out therefrom collide against each other sufficiently to form ultra-micro atomized particles with uniform and adjustable size. The ultra-micro atomized particles are sprayed out downwardly to the wafer surface under the acceleration and vertical orientation effects of an atomized particle guiding outlet to perform a reciprocating cleaning for the wafer. Other components such as an ultrasonic or megasonic generation unit, a gas shielding unit, a self-cleaning unit or a rotating unit can also be provided to perform the multifunction of the nozzle.

A method for producing a vapor deposition mask capable of satisfying both enhancement in definition and reduction in weight even when a size increased, a method for producing a vapor deposition mask device capable of aligning the vapor deposition mask to a frame with high precision, and a method for producing an organic semiconductor element capable of producing an organic semiconductor element with high definition are provided. A metal mask provided with a slit, and a resin mask that is positioned on a front surface of the metal mask and has openings corresponding to a pattern to be produced by vapor deposition arranged by lengthwise and crosswise in a plurality of rows, are stacked.

A coating apparatus includes a jig supporting a guide vane equipped with a metal sheath covering a leading edge portion; a nozzle spraying paint onto a vane body; a robot moving the nozzle; and a control unit controlling a spraying operation of the nozzle and robot. The jig includes a movable covering body adapted separably covering the metal sheath and covering an exposed portion of adhesive between a lateral edge portion of the metal sheath and the vane surface of the vane body, and a covering body drive unit moving the movable covering body between a state in which the movable covering body covers the metal sheath and a state in which the movable covering body is separated from the metal sheath while covering the metal sheath. The control unit performs control to make transition from a sheath cladding coating mode to a finish coating mode.

A paint sprayer attachment that prevents over spray mist from dispersing into the open air, thus allowing a user to operate a paint sprayer without wearing a mask, includes a spray hood, a first edger, a second edger, a first roller assembly, and a second roller assembly. The spray hood is a thin-walled, dome-like structure to which the first edger, the second edger, the first roller assembly, and the second roller assembly are attached. The first edger and the second edger enclose the sides of the spray hood, and provide non-abrasive surfaces for applying paint to a desired surface. A first paint roller from the first roller assembly and a second paint roller from the second roller assembly are positioned at opposite ends of the spray hood, wherein the first paint roller and the second paint roller enclose the front and back of the spray hood.
