Abstract:
1. A work electrodeposition coating method of performing a electrodeposition coating on a work surface by immersing a work in an electrodeposition liquid in an electrodeposition tank having a first positive electrode for supplying a low voltage and a second positive electrode for supplying a high voltage, the method comprising: a first step of causing a first robot to move the work to a first table provided with a first negative electrode corresponding to the first positive electrode; a second step of connecting the work to the first negative electrode and supplying the low voltage to the work to perform the electrodeposition coating; a third step of, when a second robot including a third negative electrode chucks the work, switching a connection condition of the third negative electrode connected to the work from the first negative electrode to a second negative electrode corresponding to the second positive electrode, and subsequently moving the work to a second table provided with the second negative electrode while performing the electrodeposition coating; and a fourth step of connecting the work to the second negative electrode and supplying the high voltage to perform the electrodeposition coating.
