PCB boards of different sizes are placed and transported for the production of PCBs of different sizes. When the loading and unloading device of PCB boards is used, the manual handling method is used for a long time, which is easy to cause muscle strain to the workers, and there are dangers in handling during work. In particular, large PCB boards are heavier during loading and unloading, and multiple workers are required to cooperate in handling and conveying, which affects production efficiency.
