The FPC film cutting machine is a device used for flexible circuit board (FPC) processing. It is mainly used to paste protective film on the FPC surface and cut as needed. Here is a detailed introduction to it:

How it works

Filming principle: Roller type coating method is usually used. The protective film is installed on the equipment. The protective film is pulled out from the coil through the rotation of the roller. At the same time, the protective film is tightly bonded to the FPC surface by using the press wheel. Some devices may also have heating functions, and the protective film can better bond to the FPC surface when bonding, improving the firmness and quality of the film.

Cutting principle: Generally, high-precision tool or laser beam is used for cutting. When cutting the tool, the tool movement trajectory is controlled through the CNC system, and the FPC and the protective film on the surface are cut according to the preset size and shape; laser cutting uses the high energy density of the laser beam to instantly convert the FPC and protective film. Melt or vaporize to achieve cutting, laser cutting has the advantages of high accuracy, narrow cut joints and small heat influence.

Equipment structure

Feeding mechanism: Responsible for transporting FPC plates to designated locations, usually using conveyor belts or rollers, and has positioning and calibration functions to ensure the position accuracy of the FPC during filming and cutting.

Film sticking mechanism: includes protective film unwinding device, film coating roller, pressing wheel, and driving device, which are used to complete the bonding operation of the protective film. The film sticking mechanism of some equipment can also adjust the pressure, speed and angle of the film.

Cutting mechanism: Depending on the cutting method, the tool cutting mechanism includes tools, tool holder, drive motor and transmission device, etc., while the laser cutting mechanism is mainly composed of lasers, laser heads, scanning galvanometers and focusing lenses.

Control system: It is the core of the equipment. It generally uses PLC or industrial computer combined with motion control card to achieve control of various links such as feeding, filming, cutting, etc. Operators can set parameters, edit programs and monitor equipment through the human-computer interface. Running status.

Material collection mechanism: used to collect FPC finished products after filming and cutting. Some also have automatic stacking or packaging functions to improve production efficiency and product quality stability.

Performance parameters

Cutting accuracy: Usually between ±0.1mm and ±0.5mm, high-precision equipment can reach ±0.05mm or even higher, mainly depending on the mechanical accuracy of the equipment, control system accuracy and cutting method.

Filming speed: Generally, it is about 1-5 meters per minute. The specific speed can be adjusted according to the material, thickness of the FPC and the characteristics of the protective film.

Larger cut size: Different from the device model and specifications, the common larger cut width is between 300-1500mm, and the length can be customized according to needs.

Suitable protective film thickness: generally can adapt to 0.05-0.5mm thickness protective film to meet the protection needs of different FPC products.

Application areas

Consumer electronics: FPCs in electronic products such as mobile phones, tablets, laptops, etc. need to use an FPC film cutting machine to paste and cut protective films during the production process to protect FPCs from being processed, assembled and used during subsequent processing, assembly and use. Injured.

Automotive Electronics: FPCs in the dashboard, navigation system, airbag and other components of the car also need to be cut through film to improve its reliability and service life in complex automotive environments.

Medical Electronics: FPCs in medical equipment, such as pacemakers, blood glucose meters, medical imaging equipment, etc., have extremely high requirements for the quality and reliability of FPCs. The FPC film cutting machine can ensure that the protective film on the FPC surface is firmly bonded. Cut to ensure the performance and safety of medical electronic equipment.
