为了对制导光纤缠绕喷胶特性进行研究,建立了基于图像处理技术的测量系统。以自主研发的制导光纤喷胶设备为试验平台,借助Matlab图像处理技术,将雾化质量和雾化锥角作为研究喷胶工艺参数的指标,建立以水为介质的雾化质量、雾化锥角与喷胶工艺参数的影响规律,并以此规律为基础对胶液的雾化效果进行试验研究,并探索工艺参数与雾化质量、雾化锥角之间的影响规律。试验结果表明工艺参数对雾化质量和雾化锥角的影响效果明显,其中雾化质量随空气压力的增大而变差,随喷胶流量的增大而改善;雾化锥角随施胶流量的增加呈现出先增后减的趋势。从工艺上验证了制导光纤缠绕试验平台可实现胶液雾化及涂覆光纤的功能,为在线精确控制施胶量和喷胶效果提供了理论依据。

In order to study the experimental study on properties of guided fiber winding and spraying adhesive, a measurement system based on image processing technology was established. By experimenting on the self-developed guided fiber glue-spraying equipment and using the Matlab image processing technique, this paper took the spray quality and spray cone angle as indicators of glue spraying and explored the relations among the spray quality, the spray cone angle and glue-spraying technological parameters. On the basis of that, this paper studied the spray effects of glue solution and examined how the spray quality and spray cone angle would work on glue-spraying technological parameters. It has been found that technological parameters have a great bearing on the spray quality and the spray cone angle. To be more specific, the spray quality would drop as the air pressure increases but improve as the spray flow rate goes up. The spray cone angle, however, would expand before dwindling when the spray flow rate increases. That the winding experiment platform of the guided fiber could make atomization of glue solution and coating of a-fiber possible was also technologically verified. It is verified from the process that the guided fiber winding test platform can realize the function of glue atomization and coating of optical fiber, which provides a theoretical basis for accurate control of sizing amount and spraying effect.
