Method and device for automatically planting optical fiber into composite materials based on fiber laying and placing

Abstract

The invention discloses a method and device for automatically planting optical fiber into composite materials based on fiber laying and placing. The device comprises a manipulator used for laying and placing single-layer prepreg tape and double-layer prepreg tape with the middle wrapped by the optical fiber, a laying and placing head is arranged at the front end of the manipulator, and a prepreg tape conveying channel used for conveying prepreg is arranged on the manipulator. In the laying and placing process, the optical fiber to be planted in is placed between two pieces of single-layer prepreg tape, and the optical fiber is wrapped in the double-layer prepreg tape so as to effectively improve the survival rate for planting the optical fiber into the composite materials. The automatic panting-in technology is adopted in the process for planting the optical fiber into the composite materials, the single-layer prepreg tape is laid and placed on a substrate to a required thickness by the laying and placing head, then the double-layer prepreg tape with the middle wrapped in optical fiber is laid and placed at the required position, then the single-layer prepreg tape is laid and placed a required thickness continuously, and namely the intelligent composite materials can be obtained. With the method, the optical fiber can be effectively prevented from twisting and shifting in the conveying process, and therefore the positioning accuracy for planting the optical fiber into the composite materials is not affected, and the planting-in efficiency and quality of the optical fiber can be improved.

Description

technical field [0001] The invention relates to the field of optical fiber intelligent composite material manufacturing, and relates to a prepreg-tape-protected optical fiber automatic implantation method and device, in particular to a fiber laying-based automatic optical fiber implantation composite material method and device. Background technique [0002] Optical fiber intelligent composite material is a kind of intelligent composite material that has been studied more at home and abroad at present. The simple intelligent composite material is formed by embedding optical fiber sensors in the composite material. When the composite material plate is subjected to external force, the composite material plate will be deformed, and the fiber optic sensor embedded in the composite material will be deformed accordingly, causing changes in the fiber optic signal. These signal changes directly reflect the internal state of the material. By processing the signal, the damage and strai...

AI Technical Summary

Problems solved by technology

The method of manually implanting optical fibers is time-consuming and laborious. It is necessary to measure the corresponding size to determine the implantation position of the optical fiber, and it is necessary to manually fix the optical fiber at the implantation position. The implantation efficiency is low. At the same time, the positioning accuracy of the optical fiber is relatively low, which cannot meet Requirements for large-scale and high-precision production in batches
