Description

Technical Field

[0001] The utility model relates to the field of flexible printed circuit (FPC) board cover film processing, and particularly to a roll-to-roll double-platform double-system laser cutting device for cover films. Background Art

[0002] Generally, a protective film is covered on the surface of an existing FPC board, mainly to cover and protect the electronic components and wires on the circuit board to prevent interference or damage from the external environment. The existing circuit board cover films are generally formed by laser cutting. Currently, the finished raw materials of FPC cover films are all in roll form, and the roll materials need to be unrolled for cutting into pieces. This processing method is not convenient for collection. Moreover, each existing FPC cover film cutting device can only process one roll of material, resulting in low processing efficiency. Setting up multiple devices will increase the occupied space and the cost is relatively high. Summary of the Utility Model
