A coating system includes coating robots configured to coat a vehicle, and an operation robot. The operation robot includes a first arm configured to turn around a first axis; a second arm configured to turn around a second axis parallel to the first axis; a third arm configured to turn around a third axis parallel to the first axis; a fourth arm configured to turn around a fourth axis perpendicular to the first axis; a fifth arm configured to turn around a fifth axis parallel to the fourth axis; and a tip jig is supported at the fifth arm and is configured to turn around a sixth axis. The sixth axis is selectively parallel to the fifth axis or perpendicular to a plane which includes the fourth axis and the fifth axis.

An apparatus for performing liquid treatment for a substrate is provided. The apparatus for performing the liquid treatment for the substrate may include a housing having a treatment space, a substrate support unit to support and rotate the substrate in the treatment space, a liquid feeding unit including a nozzle device including a central exhaust port and multiple first outer exhaust ports, which are provided in a shape of a ring to form a concentric circle with the central exhaust port to feed mutually different treating liquids onto the substrate through respective exhaust ports, and a controller to control the liquid feeding unit.

In a film forming apparatus of the first embodiment, an infrared radiation apparatus and a thin film forming nozzle are separately disposed from each other so that heating treatment performed in a heating chamber and mist spray treatment performed in a film forming chamber are not affected by each other. The film forming apparatus of the first embodiment performs the heating treatment of infrared radiation of the infrared radiation apparatus in the heating chamber and then performs the mist spray treatment of the thin film forming nozzle in the film forming chamber.

A method and system for post-processing of engineered-wood fence pickets or similar fencing components. A post-processing line in the manufacturing factory or facility, or in a post-processing location, includes a special edge-sanding process and apparatus with one or more side sanders to treat the rough edges of the engineered-wood fence picket after sawing. The edge-sanding process produces a smooth side surface on the edges, significantly reduces the number of loose fibers and/or strands, and fills in and/or reduces void spaces. After sanding, the pickets on the belt pass through an apparatus for application of a primer to the processed picket edges. Acutely-angled limited fan sprayers provide complete coverage of the edges with primer at a particular coating thickness required for encapsulation and protection of the fence picket product. The limited fan sprayers may be positioned at varying angles and orientations with respect to the belt and pickets.

The invention relates to a system and to a method for coating workpieces using a coating device, which is designed to apply a metal coating to a surface of the workpiece. According to the invention, it is provided that a plurality of coating devices, which are designed as identical coating modules, are provided and are arranged in a module group, that an input measuring station is assigned to the module group, by means of which station a surface of the face of the workpiece to be coated can be detected, that a conveying apparatus is provided, by means of which a workpiece can be supplied to one of the coating modules from the input measuring station, and that an output measuring station is assigned to the module group, by means of which station a surface of the coated face of the workpiece can be detected.

The invention relates to a coating device and to a method for metal-coating of workpieces, comprising a housing, which surrounds a working space, a retaining apparatus for retaining at least one workpiece in the working space, at least one deposition apparatus comprising a deposition nozzle for applying a metal powder to the workpiece surface to be coated, and a laser for locally melting the metal powder on the workpiece surface to form a coating, and at least one movement apparatus, by means of which the at least one deposition apparatus can be moved relative to the workpiece surface during the coating. Particularly efficient coating is made possible by at least two deposition apparatuses being arranged in the working space in the housing, which apparatuses are designed to simultaneously apply and melt metal powder.
