Pneumatic buckling device of flexible printed circuit (FPC)

Abstract

The invention discloses a pneumatic buckling device of a flexible printed circuit (FPC). The pneumatic buckling device is used for buckling the FPC and comprises a baseboard, a vertical board, a bidirectional cylinder, an upper die, a pressing block, a lower die and a pneumatic switch. The vertical board is fixed on the upper surface of the baseboard and perpendicular to the baseboard, the bidirectional cylinder comprises a cylinder body and a piston rod, the cylinder body is fixedly connected onto the vertical board, one end of the piston rod is slidingly arranged in the cylinder body, the other end of the piston rod is fixedly connected onto the upper surface of the upper die, and the piston rod can move back and forth in the direction perpendicular to the baseboard. The upper surface of the pressing block is fixedly connected onto the lower surface of the upper die, a boss is arranged on the lower surface of the pressing block, a groove matched with the boss is arranged on the upper surface of the lower die, and a plurality of splicing nails matched with the FPC and used for fixing the FPC are further arranged on the upper surface of the lower die. The pneumatic buckling device is high in processing efficiency and can effectively ensure product quality and product yield.

Description

technical field [0001] The invention relates to a pneumatic bending device, in particular to a pneumatic bending device for FPC. Background technique [0002] After the FPC completes all the processes, according to the needs of the customer's installation, it is necessary to bend and shape the finished FPC at 90 degrees and other different angles. The existing bending technology generally uses pure manual fixtures, and the bending angle according to the needs, Set the modules above and below the jig, position the product to be bent with the splicing nails on the four sides of the lower module, then manually press down the upper mold of the jig, and stay in contact with the FPC for 3 to 5 seconds, then the operator releases the jig The upper mold, the spring between the upper and lower modules automatically bounces and rises, and the bending is completed. Due to the softness of the FPC itself and the varying degrees of manual operation, the FPC will rebound to a certain exte...

AI Technical Summary

Problems solved by technology

[0003] 1. Only one piece can be operated at a time, and the processing efficiency is low, which is not conducive to mass production;

[0004] 2. The rework rate is high, and the product quality cannot be guaranteed;

[0005] 3. The operation methods of different operators make it impossible to achieve uniform specifications, and the differences in bending positions and angles directly affect the final product yield
