Description

Technical Field

[0002] FPC (flexible printed circuit) laser decapping technology refers to the use of laser technology to accurately cut or open holes on FPC to facilitate subsequent assembly and connection. Among them, FPC (flexible printed circuit) is a circuit board made of flexible substrate (such as polyimide or polyester), which is thin, bendable and foldable.

[0003] Specifically, when laser opening the FPC (flexible printed circuit), a high-energy laser beam is irradiated onto the FPC surface, instantly heating and evaporating the material, thereby achieving cutting or opening. Laser cutting can achieve micron-level precision, which is suitable for cutting complex shapes. At the same time, it can also quickly adjust cutting parameters according to different design requirements to adapt to small batch diversified production. Compared with the traditional mechanical mold punching process, it has the advantages of laser being able to accurately control the half-cut depth without damaging the underlying material, and quickly switching models with guide maps, greatly shortening the process cycle of new products.

[0004] The invention with publication number CN105101684A proposes a method for making a rigid-flexible board and laser opening the cover, wherein the FPC layer, the adhesive layer with pre-opened windows in the flexible board area, and the etching layer with a copper foil etched and slotted by laser are pressed together, and then the copper foil on the etching layer in the flexible board area is etched away, and then the cover is opened to expose the flexible board of the FPC layer.

[0060] In a specific implementation, the first processing station 22 and the second processing station 23 can both slide in the width direction of the processing table 1. When laser processing the FPC raw material plate, the first processing station 22 and the second processing station 23 are adjusted to slide backward.

[0061] In the specific implementation, the loading is completed by manually placing stacks of FPC raw material sheets and separator paper on the loading station 21, and then the grabbing mechanism 4 grabs the odd-numbered FPC raw material sheets and the even-numbered FPC raw material sheets respectively, and supplies them to the first processing station 22 and the second processing station 23 respectively, thereby completing the feeding processing of the first processing station 22 and the second processing station 23.

[0073] Through the NG product tray 61, when NG products are generated after processing, the NG product tray 61 can be driven by the third cylinder 62 to move to the top of the unloading station 24. At this time, the NG product tray 61 covers the unloading station 24, and the NG products are grabbed by the grabbing mechanism 4 and moved to the unloading station 24 and unloaded. At this time, the NG products fall and are collected on the NG product tray 61, and then the NG product tray 61 is driven by the third cylinder 62 to move away from the unloading station 24, thereby completing the convenient classification, collection and processing of NG products for easy use.
