A spray device is provided. The spray device is capable of using in a production process of a liquid crystal display and disposed in a spray chamber. The spray device includes an upper rack, a connector, an eccentric wheel, and a motor. The eccentric wheel includes a center hole, a plurality of eccentric holes, and a connecting rod. The center hole is fixedly connected to the eccentric wheel. The eccentric holes are disposed on the eccentric wheel. The connecting rod is fixedly mounted on one of the eccentric holes. A rocker is sleeved on the connecting rod to realize a rotatable connection. The motor is configured to drive the eccentric wheel to rotate. The connecting rod is configured to rotate with the eccentric wheel to drive the rocker to realize a reciprocating motion of the upper rack.

The invention is directed at systems and methods which provide for effective cleaning and drying of vehicles of different shapes and sizes. The invention in one example includes a vehicle washing apparatus comprising a conveyor system to move a vehicle along a path, and a bridge assembly supported above a vehicle and moveable along the length thereof. At least one trolley assembly is operatively supported by the bridge assembly and is moveable in a direction generally transverse to the movement of the bridge assembly. At least one cleaning arm assembly for delivering cleaning fluid to or for brushing the surface of a vehicle is operatively supported by the at least one trolley assembly or bridge. The cleaning arm assembly is moveable with the bridge assembly along the length of the vehicle, and transversely with the at least one trolley assembly to adjust the location of the cleaning arm relative to the vehicle, wherein the bridge assembly moves in association with movement of the vehicle to position the cleaning arm assembly adjacent at least a portion of the front, sides and rear of the vehicle as it moves along the path. A variable impact or patterning spray arm or drying system is also provided.

A self-cleaning, automated apparatus with a filter for fluids includes a nozzle unit assembly that has a first tube inside a second tube. Each of the tubes has a different pattern of one or more slots or holes. One tube rotates while the other is fixed, so that part of the pattern of one coincides with the other at times, resulting in a jet of cleaning fluid that removes debris from a filter. The filter is rotated so the jet can reach all parts to be cleaned. The pattern of the rotating tube may approximate a helix and the pattern of the fixed tube may approximate a line.

Provided is a compact sized low flow rate fluidic nozzle insert. The fluidic nozzle insert may include a fluidic oscillator chip on a front face having a flat-top interaction region, and a manifold on a back face, located opposite the front face, to house fluid. The fluidic nozzle insert may further include at least one feed having a u-shape connecting the front face and back face for the transport of fluid from the manifold, at least one power nozzle oriented toward the front face for directing fluid from the at least one feed to the interaction region of the fluidic oscillator chip, and a v-shaped outlet at the bottom of the interaction region defined by two flat walls for the passage of fluid from the interaction region to the outside of the fluidic nozzle insert in a fan pattern. The produced spray fan pattern may be uniform and fluid nozzle may work well with high viscosity fluids.

A method of controlling application of at least one material to a substrate is provided. The method includes configuring at least one array having a plurality of micro-applicators such that a subset of the micro-applicators is individually addressable to apply the at least one material to the substrate. Individually addressing the subset of micro-applicators provides control of a pattern width of a coating applied to a substrate, control of a flow rate of the material applied to the substrate, control of an angle of application of the material to the substrate, control of which and how many materials are applied to the substrate, and combinations thereof.
