The UV coated cell phone case 100 is transferred from the secondary coater 70, wherein the IR dryer 80 does not operate and is extracted while being dried by the UV dryer 90.

Meanwhile, a conventional air curtain device 110 is installed between the primary coater 40, the IR dryer 50, and the secondary coater 70, and the IR and UV dryers 80 and 90, wherein the primary and secondary It is to block paint dust and the like scattered in the air generated by the coater (40, 70).

In addition, the sensor (S) is a static eliminator and a vibration damper 20, a primary coating machine 40, an IR dryer 50, a vibration damper 60, a secondary coating machine 70, an IR and UV dryer ( It is installed in place of 80,90, to detect the conveyed or stopped state of the jig 10 along the conveyor 200 so that the overall operation is made smoothly.

The primer coater 120 is disposed between the antistatic and vibration damper 20 and the primary coater 40, so that the coating of the paint and the like is smoothly performed during the first undercoating.

The primer coater 120 is made of the same structure as the primary coater, and rotated by the rotating part 140 and the rotating part 140 to rotate the rotating body 13 of the transferred jig 10, spraying Apply the paint and the anti-rust material having a predetermined color to the mobile phone case 100 by the gun 42 so that the coating is smoothly applied during the first undercoat coating, which will be described later. And a coating liquid collector 43 for discharging the back. (As described above, the rotating unit and the coating liquid collector have the same structure).

The hot air dryer 130 is installed between the primer coater 120 and the primary coater 40. The hot air dryer 130 is installed in the work room B and the work room B installed in the conveyor 200 line. Is installed, but the rotation induction unit 150 for rotating / advancing the rotating body 13 of the transferred jig 10 is installed. (The rotation induction portion is made in the same structure as described above and will not be duplicated)

The hot air dryer 130 is made of a conventional structure, by applying hot air to meet the maximum conditions for applying the anti-rust material or paint attached to the mobile phone case by the primary coater (40).

Referring to the operation and effect according to the present invention as described above, by mounting a plurality of cell phone case 100 in one jig 10 in a batch type, put on the conveyor 200 proceeds in series of inline type, When the jig 10 transferred first enters the static eliminator and the vibration suppressor 20, the mobile phone case 100 is rotated as the rotating body 13 of the jig 10 is rotated by first detecting and operating the rotating unit. Subsequently, the brush 25 and the air supply unit 29 are operated to remove static electricity, particles, dust, and the like, and are transferred.

When the transferred mobile phone case 100 enters the inside of the primary coater 40, the mobile phone case 100 is first rotated by the rotating unit 140, and then the spray gun 42 is set according to a set program. The first coat is applied by the operation of).

When the primary coated cell phone case 100 enters the inside of the IR dryer 50 as described above, the mobile phone case 100 is rotated and dried by the operation of the rotation induction part 150.
