[0002] Painting refers to the process of applying paint on the surface of an object and forming a protective, decorative or other special functional coating through a specific process. This process mainly includes surface treatment (such as rust removal, oil removal, polishing, etc.), paint preparation, spraying (can also be brushing or roller coating), leveling, drying and post-processing. Painting is widely used in various industries, such as automobile manufacturing, shipbuilding, furniture production, building decoration, machinery manufacturing, electronic products and other fields. The main purpose is to prevent corrosion, wear, beautify the appearance, improve product quality and extend service life.

[0003] The coating production line has introduced one-click integrated control technology from traditional single-machine control, which is composed of database, Internet of Things, industrial switch, cloud server, equipment controller, and each single machine of the production line. It realizes the whole line control and can support the master control to switch the formula with one click or read and switch the production process formula data through barcode, RFID and other scanning, so as to realize flexible production needs.

[0004] The skid is an integrated device that integrates equipment, instrument control, electrical, piping, insulation, anti-corrosion and other professional elements to achieve specific process functions. The characteristic of this device is that the equipment, valve components and pipelines are combined into a module, and then assembled on a base to form a whole with independent functions. It can be moved, transported and hoisted as a whole. The mother frame skid used for the coating production line refers to the frame integration architecture of the coating integrated equipment.
