摘要: The disclosure provides a resin cleaning device and method. The resin cleaning device includes a control system, a treatment unit, a driving unit, and a feedback assembly. The treatment unit, the driving unit, and the feedback assembly are respectively in communication connection with the control system. The treatment unit is configured for treating a member-to-be-cleaned so as to reduce a viscosity of resin on the member-to-be-cleaned. The driving unit is configured for driving the member-to-be-cleaned to rotate. The feedback assembly is configured for acquiring a position signal of the member-to-be-cleaned and feeding the position signal back to the control system, such that the control system controls the treatment unit and the driving unit according to the position signal. Through the above manner, a more intelligent resin cleaning process with a better cleaning effect may be realized.
