Description

Technical Field

[0001] This invention relates to the field of sheet metal processing technology, specifically to an adjustable bonding mechanism for reinforcing sheets. Background Technology

[0002] Flexible printed circuits (FPCs), due to their flexibility, thinness, and lightweight properties, have been widely used in smartphones, wearable devices, and other fields. However, the inherent drawbacks of FPCs, such as their susceptibility to bending and insufficient connection reliability, still limit their further development. To improve the performance and reliability of FPCs, reinforcing bonding technology has been widely adopted. Its main principle is to bond reinforcing materials, such as thin film materials or reinforcement materials, to critical locations on the FPC to enhance its strength, stiffness, and bending resistance.

[0003] Current FPC reinforcement bonding methods primarily rely on manual operation, resulting in low efficiency, high cost, and difficulties in achieving precise positioning, repeatability, and consistency, making it difficult to meet the production demands of high-end electronic products. Current FPC reinforcement attachment technology mainly depends on manual operation, which is inefficient, labor-intensive, and struggles to guarantee bonding accuracy and consistency. Furthermore, most existing FPC reinforcement bonding equipment can only reinforce a single location on the FPC, failing to meet the need for reinforcement bonding at multiple different locations. Existing automated equipment mostly achieves only partial automation, such as automatic conveying or positioning, lacking a fully automated reinforcement bonding solution.
