Description

ELECTRO PAINTING DEVICE POSSIBLE OF PARTIAL PAINTING [0002]

The present invention relates to a coating apparatus. More particularly, the present invention relates to an electrodeposition coating apparatus that can partially coat an object using electricity.

Electrodeposition coating is an electrophoresis coating. Electrodeposition coating is to paint the surface of the material to be painted by getting the object to the special paint. The electrodeposition coating is used for undercoating. The electrodeposition coating is excellent in anticorrosive properties and can easily coat an object having a complicated shape. Further, the thickness of the coating film can be precisely controlled by controlling the electric current of the object having a complicated shape. In addition, there is a feature that the closed end is excellent in the closed cross section, the arrival efficiency is good, and the paint loss is small. Furthermore, the electrodeposition coating is characterized by low defects such as surface defects and bubbles, high safety because it does not use water-based paints, and low use of volatile organic compounds. However, the electrodeposition coating is required to satisfy the current flowing conditions, which is contrary to the advantages of the electrodeposition coating as described above. In addition, electrodeposition coating can not be partially painted because the paint is applied to the special paint to obtain the object. In detail, there is a problem that an error occurs in the process due to the screw coating when the screw is engaged in the process of coating the parts such as the unwanted screw thread or the joint part because the partial coating is impossible.

The prior art document is characterized in that it includes a current supplying part for supplying a cathode current having a different length to each other. However, in the prior art, the coating time of the coating material is controlled by changing the supplying time of the cathode current, but partial coating is not possible except for the position that the user does not want.

Furthermore, the first conductive portion 211 can be electrodeposited only when it is received in the coating material 101 stored in the electrodeposition tank 100. In detail, the first conductive portion 211 can be electrodeposited when the substrate 10 is completely received up to the top of the coating 101 stored in the electrodeposition tank 100. The first conductive portion 211 supplies the first negative electrode current a1 to the coating material 10 when the coating material 10 is completely contained in the coating material 101 stored in the electrodeposition tank 100, ) Can be electrodeposited.

More specifically, the second rail 220 is electrically connected to the second power supply unit 260 and supplies current to the solenoid unit 500 through the second roller 320. The second rail 220 may be divided into a cathode conductive portion 2211 and a cathode conductive portion 2212 along the longitudinal direction. At this time, it is preferable that the anode conductive portion 2211 and the cathode conductive portion 2212 are insulated from each other.
