Conveying device, fan blade scanning system and fan blade scanning method

A conveying device for scanning a fan blade, comprising:

• a driving conveyor comprising a main driving member and a main body member, wherein the main body member is provided with a first mounting portion configured to fixedly mount a first end of the fan blade;
• and
• a driven conveyor provided with a second mounting portion configured to fixedly mount a second end of the fan blade;
• wherein in the case that the driving conveyor moves, the fan blade and the driven conveyor are driven to move, so that the fan blade passes through a scanning area of a scanning device,
• wherein the main body member comprises:
• a carrier member connected with the main driving member so that the main driving member drives the carrier member to move at a first set speed;
• and
• a micro-motion member movably arranged on the carrier member, wherein in the case that the carrier member stops moving, the micro-motion member drives the fan blade and the driven conveyor to perform micro-motion at a second set speed.
