Abstract:
A scratch resistant coating application system for a vehicle comprising:a pressurized reservoir having an output opening where a first end of a discharging line is connected, the pressurized reservoir storing aqueous emulsion; a feeder having an input opening where a second end of the discharging line is connected and an output opening where a first end of a feeding line is connected, the feeder releasing regulated aqueous emulsion into the feeding line, wherein the feeder comprises, a feeder cylinder connected to the pressurized reservoir via the discharging line and to a sprayer via the second end of the feeding line, wherein the feeder cylinder is connected to the sprayer for feeding the aqueous emulsion from the pressurized reservoir to the sprayer and wherein the sprayer is for spraying the aqueous emulsion out to atmosphere, a feeder plunger tightly inserted into the feeder cylinder, a long cylindrical piston rod of which one end is connected to the feeder plunger, a motor having a rotational shaft which is connected to the piston rod so as to convert a rotational force of the motor into a reciprocating movement of the piston rod and the feeder plunger, a manometer mounted on the feeding line for detecting feeding pressure, and a controller electrically connected to the motor and the manometer for controlling the rotational force of the motor on the basis of a feeding pressure level detected by the manometer; a robot having a robot arm on which the feeder and the sprayer are mounted, the robot arm carrying the sprayer; a visual system mounted on a ceiling of a work area for detecting a vehicle's position; and a central control unit electrically connected to the pressurized reservoir, the feeder, the robot, and the visual system for controlling the pressurized reservoir, the feeder, and the robot on the basis of data from the feeder and the visual system.
