FPC bending machine adapts pressure to different boards

product structure
The primary goal of equipment structure design is high rigidity and stability, which usually includes:

• High rigidity frame: Made of high-quality cast iron or steel structure, ensuring long-term deformation resistance and providing a foundation for high precision.

• Precision transmission system: The core consists of servo motors paired with high-precision ball screws or linear motors to achieve motion control with nanometer resolution.

• Modular work unit: including specialized vacuum fixtures that can be quickly replaced (for attaching and fixing FPC), and multi degree of freedom bending actuators (capable of performing actions such as pressing, folding, curling, etc.).

• Integrated control system: Industrial PC and multi axis motion controller collaborate to handle motion logic, human-computer interaction, and data management.

FPC bending machine adapts pressure to different boards

Adaptation pressure for different boards
This is the key to measuring the adaptability of equipment processes. The mechanical properties (elastic modulus, yield strength) of FPC with different materials and structures (such as single-layer PI substrate, multi-layer composite material, FPC with reinforcement board) vary significantly. Professional bending machines have:

• High resolution pressure control system: By using precision electric cylinders or servo pressure devices, the bending pressure can be infinitely and accurately controlled (ranging from a few newtons to hundreds of newtons).

• Parameterized programming: The optimal "pressure speed position" parameter group can be stored in the program, which can be called with one click for different sheets to ensure both forming and avoiding circuit breakage or rebound caused by excessive pressure or insufficient pressure.

Temperature control system
Advanced features designed for handling special materials, such as certain cover films or adhesives that require hot bending:

• Controllable heating module: integrated with a constant temperature heating pressure knife or an independent hot air device at the bend.

• Precise temperature control: precise control within the range of room temperature to 300 ℃ (accuracy ± 1-3 ℃), temporarily softening the material of specific parts of FPC, thereby achieving smooth bending with smaller radius and greatly reducing internal stress and crack risk.

重要性
In the trend of highly integrated and foldable consumer electronics, FPC bending machine is the core process equipment for achieving three-dimensional high-density interconnection. It replaces inefficient and unreliable manual operations, ensuring consistency, high yield, and high reliability in mass production. It is a key link connecting FPC production and whole machine assembly, directly affecting the performance and quality of the final product.

working principle
FPC bending machine is an automated forming equipment based on precision motion control. Its core is to drive high rigidity mechanical structures (bends) through computer programming, apply controllable force and motion to the flexible circuit board (FPC) precisely positioned by the fixture, causing it to undergo precise plastic bending at the predetermined position, forming a complex three-dimensional structure to meet the assembly requirements of modern electronic products with compact internal space.
