Description

Technical Field

[0001] This utility model relates to the field of winding machine technology, and in particular to a flexible circuit board winding machine. Background Technology

[0002] In the production of flexible circuits, the winding device plays a crucial role. Flexible circuits are characterized by their thinness, lightness, and flexibility, and the winding device neatly winds the produced flexible circuits according to specific specifications and requirements. Through precise control, it ensures uniform winding tension, preventing problems such as stretching, deformation, or wrinkling of the flexible circuits during winding, thereby guaranteeing product quality and performance. The winding device also improves production efficiency, enables automated winding operations, reduces manual intervention, and lowers labor intensity and production costs. Furthermore, it can adjust parameters such as winding diameter and speed according to different product needs, adapting to diverse production requirements and facilitating subsequent processing, transportation, and storage of flexible circuits. It is an indispensable key piece of equipment in flexible circuit production.

[0003] Currently, most common flexible circuit board winding devices use direct winding. In this mode, the layers of the flexible circuit board are tightly bonded together, and friction is easily generated due to relative sliding during winding and unwinding. Since the copper layer, insulating substrate, and cover film on the surface of the flexible circuit board are relatively fragile, the mechanical stress generated by friction can easily cause scratches and cracks in the copper layer, and even damage to the insulating layer, thus affecting the circuit conductivity and overall reliability.
