The present invention relates to the field of semiconductor manufacturing technology, more particularly to a swing spray device of a cleaning apparatus and a cleaning method. The swing spray device comprises a spray arm, a spray head and a driving unit. The spray head is connected with the spray arm, and is controlled to swim by the driving unit. The spray head is hinged with the spray arm to form a first hinge joint. The driving unit is an air cylinder; the piston rod of the air cylinder is connected with the spray head. The piston rod is hinged with the spray head to form a second hinge joint. Therefore, the better cleaning effects can be achieved both in the center and the edge of the wafer.

A multiple pre-orifice apparatus for a sprayer nozzle body with an upper end connected to a liquid source, a nozzle tip releasably mounted at a lower end thereof, and a channel between the upper and lower ends of the nozzle body. The apparatus comprises a sleeve assembly comprising a sleeve closed at an upper portion thereof by a top orifice plate defining a top orifice, and closed at a lower portion thereof by a bottom orifice plate defining a bottom orifice such that a sleeve turbulence chamber is formed between the top and bottom orifice plates. The sleeve assembly is secured in the channel such that a nozzle turbulence chamber is formed between the bottom orifice plate and the nozzle tip. The area of the flow opening in the nozzle tip is greater than the area of the top orifice which is greater than the area of the bottom orifice.

In one aspect, a system for monitoring a level of hydraulic fluid in an agricultural sprayer includes a drive system, a hydraulic fluid system, and a fill level sensor. The system also includes a computing system communicatively coupled to both the drive system and the fill level sensor. The computing system is configured to monitor the level of hydraulic fluid within the hydraulic fluid reservoir based on data received from the fill level sensor. The computing system is further configured to detect a leak condition in the hydraulic fluid system based at least in part on the monitored level of the hydraulic fluid within the hydraulic fluid reservoir and control an operation of the drive system to reduce the ground speed of the agricultural sprayer in response to detecting the leak condition.

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.

Application of coverage product on a surface using a print head that is mounted on a robot arm, and that is made up of a body equipped with at least one printing nozzle. A method includes a) defining a strip of surface to be coated, b) defining a trajectory for the strip of surface, c) removing a strip of surface from an information sheet modelling the surface to be coated, d) restarting at a) until the modelled surface to be coated becomes a null area, e) defining an activation program for each print head nozzle on each trajectory, and f) applying the coverage product by activating each print head nozzle on the different trajectories depending on the orientation of the print head at each remarkable point, based on the activation program.
