By measuring a position of a spray gun relative to a physical surface to coat, using data on technical characteristics of the spray gun, like a spray cone the spray gun may produce and data on a coating fluid used, characteristics of a coating layer thus physically deposited may be reconstructed. With data being recording during the spray job, this is faster and more accurate than measuring layer thickness at various locations, either pre-determined or randomly. By determining flow characteristics in a spray cone and position of the spray cone relative to the surface over time and using a model of the spray cone, deposition of the layer of coating may be determined and the final layer, cured or uncured, may be reconstructed, including thickness.

Provided are an ink-jet type vehicle coating machine and an ink-jet type vehicle coating method that enable formation of a uniform coating film thickness at a coating portion including an end of a vehicle. In a state where a longitudinal direction of a nozzle head 53 is orthogonal to a scanning direction, a first nozzle array 55A and a second nozzle array 55B are disposed such that droplets discharged from nozzles 54 of the second nozzle array 55B are discharged to intermediate portions between droplets discharged from nozzles 54 adjacent to each other in the first nozzle array 55A. In addition, on the basis of trajectory data for moving the nozzle head 53, attitude data for keeping the longitudinal direction of the nozzle head 53 perpendicular to a main scanning direction of the nozzle head 53 is formed. An arm control unit 110 controls a robot arm on the basis of the trajectory data and attitude data such that, in a state where the nozzle head 53 performs coating while moving in the main scanning direction, the longitudinal direction of the nozzle head 53 is kept perpendicular to the main scanning direction.

A liquid delivery system including a spray nozzle that includes a spray tip. The spray nozzle receives liquid via a liquid supply line. The spray tip of the spray nozzle generates an atomized liquid spray output when the liquid flowing through the spray nozzle passes through the spray tip. The spray nozzle includes a fluid control valve and a flow meter. The fluid control valve controls a flow rate of the liquid dispensed by the spray nozzle. The flow meter determines a flow rate of the liquid dispensed by the spray nozzle. The spray nozzle also includes a housing configured to retain and support the fluid control valve and the flow meter. The liquid delivery system includes a controller that provides feedback and control of the spray nozzle by receiving a flow rate signal from the flow meter and outputting a control signal to the fluid control valve.

Methods and apparatus for removing deposits in self-assembled monolayer (SAM) based selective deposition process schemes using cryogenic gas streams are described. Some methods include removing deposits in self-assembled monolayer (SAM) based selective depositions by exposing the substrate to cryogenic aerosols to remove undesired deposition on SAM protected surfaces.
