The coating method using the coating system capable of scanning the coating error according to the present invention is composed of six steps. The coating method according to the present invention acquires paint spray information of an object through scanning of the scan unit 30 after the paint spraying operation and then compares the paint spray information with the normal spray information stored in the storage means 52, It is possible to judge whether or not it is possible.

According to the present invention, first, the conveyance unit 10 causes the object placed on the loading unit to be loaded onto the conveyor 60 (S10). Next, the compressed air supply pump 22 is driven to supply the compressed air to the paint tank 21. When the paint is pumped to the spray 23 from the paint tank 21 by the compressed air, the spray 23 (Step S20). In this case, the paint is sprayed onto the object loaded with the conveyor. According to the present invention, the spray 23 can adjust the spraying range through the injection port 232, so that the spraying range of the paint can be adjusted according to the size and / or type of the object .

After the paint is sprayed on the object in step S20, the paint is naturally dried for 15 minutes to 25 minutes so as to evaporate the volatile matter from the paint sprayed on the object (S30). This is because there is a risk that the volatile matter may explode if the volatile matter is dried without being evaporated from the paint sprayed on the object.

In another embodiment of the coating method according to the present invention, when it is determined in step S40 that the paint is not uniformly sprayed on the object, the paint spraying information of the object is compared with the normal spraying information stored in the storage means 52, (Not shown) for causing the display means 51 to display an overflow or overflowed portion. At this time, as described above, the control unit 50 compares the paint spraying information of the object with the normal spraying information of the storage unit 52, and when the paint is insufficiently sprayed, the control unit 50 calculates the paint pumping amount of the compressed air supply pump 22 The spray time of the spray 23 is controlled so as to be controlled. When the paint is overflowed, the amount of paint pumped by the compressed air supply pump 22 and the spray time of the spray 23 are controlled to be controlled.

As described above, according to the present invention, the paint spraying information of the object is scanned by the scan unit and displayed by the display unit, thereby confirming the painting error. When it is determined that the paint is uniformly sprayed on the object, The injection information is cumulatively stored in the storage means, and an average value is calculated based on the accumulated injection information and displayed on the display means.
