By inserting single curtain pieces with holes into the single curtain pieces without holes, the effect of micro-ventilation of the rolling shutter curtain pieces can be achieved. The existing curtain piece sorting process is to manually pick up the required single curtain pieces from the loading rack, and then place them on the assembly workbench for assembly. However, the cuts at both ends of the curtain pieces are prone to scratches, and after manually taking them to the assembly workbench, the insertion order of the single curtain pieces needs to be confirmed again.
