Dross removal device, dross removal method, dross detection device and dross detection method

摘要

A new and improved dross removal device and a dross removal method capable of more efficiently collecting dross on a bath surface using a dross robot are provided. In order to solve the above problem, according to an aspect of the present invention, a dross robot that collects dross on the bath surface existing on the bath surface of the plating bath, a dross sensor that measures the intensity of infrared rays from the bath surface of the plating bath, and , The dross sensor control device that specifies the position of the dross on the bath surface based on the amount of change over time in the intensity of the infrared rays, and the dross robot to collect the dross on the bath surface at the location specified by the dross sensor control device. There is provided a dross removal device, characterized in that it comprises a dross robot control device.
