Description

Technical Field

[0001] This utility model relates to the field of flexible circuit board manufacturing technology, specifically an automatic feeding device for flexible circuit boards. Background Technology

[0002] Flexible printed circuit boards (FPCBs), also known as "flexible boards," are printed circuits made from flexible insulating substrates. Flexible circuits offer excellent electrical performance, meet the design needs of smaller and higher-density installations, and help reduce assembly steps and enhance reliability. They can be freely bent, rolled, and folded, and can withstand millions of dynamic bends without damaging the wires. Flexible circuit boards can greatly reduce the size and weight of electronic products, meeting the needs of electronic products developing towards high density, miniaturization, and high reliability. Flexible circuit boards require processes such as material cutting, drilling, electroplating, exposure, and lamination. Therefore, the manufacturing process of flexible circuit boards requires multiple loading and unloading operations.

[0003] In the current process of processing flexible printed circuit boards (FPCBs), workers need to place the FPCBs into the FPCB production machine for processing. After processing, the FPCBs need to be removed from the machine frame and transported to the product area for storage. The entire feeding process requires worker participation. This feeding and unloading method prevents the efficiency of the FPCB production machine from being further improved, requiring overtime work to complete the work target, which is time-consuming and labor-intensive.

[0004] Based on this, an automatic feeding device for flexible circuit boards is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content
