[0002] Flexible printed circuits (FPCs), also known as FPCs, are a type of printed circuit board (PCB) made from a highly reliable, flexible, and highly flexible insulating substrate. FPC manufacturing typically involves processes such as laser cutting, automated optical inspection (AIO), and automated test equipment (ET) testing. Each of these processes requires the FPC to be loaded into a carrier, transported to the desired location, and then undergo the corresponding production steps.

[0003] In current flexible circuit board transportation, two layers of magnetic aluminum alloy plates are usually attracted to each other to clamp the FPC. The FPC is then transported to the desired location using an aluminum alloy carrier. However, during the transportation process, the FPC often needs to be transferred from carrier 1 to carrier 2. Therefore, how to quickly solve the above problem requires the design of a device that can quickly replace carriers.
