Coating determination device of coating head and coating system

A coating system, comprising:

• a coating head comprising a plurality of nozzles;
• a moving unit disposed within a coating chamber subjected to an explosion-proof treatment and configured to move the coating head along a workpiece in a direction;
• at least one camera unit for capturing an image of the workpiece;
• a coating determining device comprising:
• an image acquiring unit for acquiring one or more images of the workpiece and generate a 3-dimensional model of the workpiece,
• wherein the image acquiring unit determines a coating pattern for coating the workpiece using the 3-dimensional model,
• a determination unit for determining, based on the one or more images acquired by the image acquiring unit, whether coating the workpiece is implemented normally, and
• wherein the coating head comprises a control unit for controlling ejection of paint at the plurality of nozzles for each nozzle,
• wherein the control unit cooperates with the coating head to move in a first direction, and applies to the workpiece with a pattern for determining whether there is an ejecting defect for the paint using the plurality of nozzles comprised by the coating head, and
• wherein the determination unit determines, based on one or more images of the workpiece coated with the pattern for determination, whether coating the workpiece is implemented normally;
• and
• a cleaning unit for cleaning the plurality of nozzles comprised by the coating head,
• wherein when the coating determining device of the coating head determines that coating the workpiece is not implemented normally, the cleaning unit cleans the plurality of nozzles comprised by the coating head.
