多层隔热组件智能投影辅助裁剪系统研制与应用

Development and Application of Intelligent Projection Assisted Tailoring System for Multi-layer Insulation Blankets

针对传统纯手工制作多层隔热组件难以满足小卫星批产研制对其制作效率和一致性要求高的问题,建立一种基于视觉传感技术的多层隔热组件智能投影辅助裁剪系统;系统主要包括投影仪、相机和控制软件,可通过深度相机、投影仪和系统标定,实现投影仪图像坐标系与工件坐标系定位对齐,确保多层工艺图纸1∶1定位投影;可用于指导多层隔热组裁剪、尼龙搭扣和聚酰亚胺销钉的安装工作;经试验及应用验证,系统投影比例和定位误差满足设计要求,能够显著提高多层制作效率和一致性,并可建立通用产品多层工艺信息库,实现工艺知识积累和快速调用。

It is difficult for a traditional handmade multi-layer insulation blanket to meet the high production efficiency and consistency requirements for the batch production of small satellites,to address this issue,an intelligent projection assisted tailoring system for multi-layer insulation blankets based on vision sensing technology is presented.The system mainly consists of a projector,a camera,and control software.Through the depth calibration of the camera,projector and system,the alignment between the project image coordinate system and the workpiece coordinate system is achieved to ensure a 1∶1 positioning projection of the multi-layer process drawing.The system can be used to guide the cutting of the multi-layer insulation blankets,the velcro and installation of polyimide pin.Experiment and application show that the projection ratio and positioning error of the system meet the design requirements,and can significantly improve the efficiency and consistency of multi-layer insulation blankets,and establish a general product multi-layer process information database to realize the accumulation of process knowledge and rapid call.
