以车载终端项目开发过程中遇到的单件小批量印刷电路板(PCB)塑料安装盒为研究对象。根据单件小批量PCB关键尺寸及功能端口要求，采用三坐标测量等方法获取该PCB点云数据。借助Imageware软件等，提取该PCB关键尺寸参数，确定该PCB安装盒设计参数。基于Solid Works软件完成该PCB塑料安装盒参数化设计，形成三维造型，并完成虚拟装配及干涉检查。利用3D打印技术，完成PCB塑料安装盒产品工程样机快速原型制造。对项目开发过程中单件小批量塑料安装盒的快速和经济制造具有一定的工程应用价值。%Plastic box for single unit and small batch printed circuit board (PCB) was taken as research object,which is encountered in the process of vehicle terminal project developing. According to the key size and functional port requirements of the PCB,point cloud data were acquired by three coordinate measuring and other methods. Imageware software was used to reconstruct the PCB model,basic size parameters of the PCB could be got and then design parameters of plastic box for the PCB could be determined. Design of the plastic box for the PCB was completed based on Solid Works software,then 3D modeling of plastic box for the PCB was gained,virtual assembly and interference checking were also finished. Up Plus 2 rapid prototype machine was used to manufacture plastic box for the PCB rapidly based on 3D printing technology,then prototype of plastic box for the PCB was obtained. It is of certain engineering significant for single unit and small batch manufacturing of plastic box.
