Work electrodeposition coating method and electrodeposition coating device

A work electrodeposition coating device for performing an electrodeposition coating on a work surface by immersing a work in an electrodeposition liquid in an electrodeposition tank provided with a first positive electrode for supplying a low voltage and a second positive electrode for supplying a high voltage,

• the device including:
• a first table on which the work is to be connected to a first negative electrode corresponding to the first positive electrode and supplied with the low voltage for performing the electrodeposition coating;
• a first robot for placing the work on the first table;
• a second robot provided with a third negative electrode and configured such that a connection condition of the third negative electrode connected to the work is switched from the first negative electrode to the second negative electrode corresponding to the second positive electrode when the second robot chucks the work, and subsequently the second robot moves the work to a second table provided with the second negative electrode while performing the electrodeposition coating;
• the second table for allowing the work to be connected to the second negative electrode and supplied with the high voltage for performing the electrodeposition coating;
• and
• a third robot for disconnecting the work from the second negative electrode and conveying the work.
