Abstract:

In view of the defect that large super-long piercing steel needles of the integrated piercing steel needles array to produce 3-D fabric are laid by manual operation, a piercing template frock used for steel needles laying automatically is designed, and the 3-D fabric integrated piercing steel needles array laying device also is developed. The device is composed of a high level of repeat accuracy mobile platform, fuselage and steel needle storage and launching mechanism, et al. The device locates the isometric and close-packing precise micro holes of piercing template by red cross lasers. the control system uses a touch screen as the human-machine interface, and use PLC which can output multi-channel pulse to control the servo motors of the mobile platform and the closed loop stepping motor of the steel needle storage the launching mechanism. The control system guarantees the working reliability of the device. In order to verify the feasibility of working principle of laying device, a T-shaped cross section steel needles array laying experiment is achieved. The result shows that the laying device gas feasible principle and reliable operation.

Key words: integrated piercing, steel needles array, laying device, 3-D fabric
