Resin cleaning device and method

A resin cleaning device, comprising:

• a control system;
• a treatment unit, which is in communication connection with the control system and is configured for treating a member-to-be-cleaned so as to reduce a viscosity of resin on the member-to-be-cleaned;
• a driving unit, which is in communication connection with the control system and is configured for driving the member-to-be-cleaned to rotate;
• and
• a feedback assembly, which is in communication connection with the control system and 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;
• wherein the feedback assembly comprises:
• a sensing element, which is in communication connection with the control system and has a trigger station;
• and
• a trigger element, which is connected with the driving unit, and is driven by the driving unit to rotate relative to the sensing element,
• wherein when the trigger element rotates to the trigger station, the sensing element feeds the position signal back to the control system.
