【摘要】：扫描仪数码后背是一种小型高精度光机电一体化产品，主要作用是为了进行图像的输入和数字化保存，它已成为当今社会很多用户使用的一种图像处理设备，，其广泛用于摄影，专业壁画，博物馆文物收藏等需要高精度数字化产品的领域，在现阶段，开发一款高性价比的扫描仪数码后背就非常重要了。 本论文来源于在读研期间参与开发扫描仪所做的相关工作。在了解了国内外相关产品并实际考察了国内市场的需求后，文章中对扫描仪数码后背的工作原理、技术指标、整体结构、强度等进行了深入的分析。最后提出了扫描仪数码后背的设计思想以及各模块的组成。本论文通过对光学成像的分析，机械传动部分的简单论述，主要对后背箱体和控制部分箱体的设计，后背和相机机身卡口设计，以上均采用三维软件Solidworks完成了对扫描仪数码后背零部件的实体建模。 最后文章还利用有限元软件ANSYS软件对玛米亚RB67机身变形量进行了静态分析，分析了变形量对扫描结果的影响，并且还提出了对机身变形量改进的方法，其在误差允许的范围内，扫描结果能够让用户接受，进一步达到设计目的，提高设备精度和稳定性。
[Abstract]:Scanner digital back is a small high precision optical mechanical and electrical integration product, the main role is to carry out image input and digital preservation, it has become a kind of image processing equipment used by many users in today's society, it is widely used in photography, Professional murals, museum cultural relics collection and other areas requiring high precision digital products, at this stage, the development of a cost-effective scanner digital back is very important. This paper comes from the work of developing scanners during graduate school. After understanding the related products at home and abroad and investigating the demand of domestic market, the working principle, technical index, overall structure and strength of the digital back of scanner are analyzed deeply in this paper. Finally, the design idea of the digital back of scanner and the composition of each module are put forward. Through the analysis of the optical imaging, the brief discussion of the mechanical transmission part, the design of the back box and the control part of the box, the design of the back and camera fuselage bayonet, All above have completed the solid modeling of the digital back parts of the scanner by using the three-dimensional software Solidworks. Finally, the static analysis of the deformation of the RB67 fuselage is carried out by using the finite element software ANSYS, and the influence of the deformation on the scanning result is analyzed, and the method of improving the deformation of the fuselage is put forward, which is within the range of the error allowed. The scan results can be accepted by the user, and the design goal can be further achieved, and the accuracy and stability of the equipment can be improved.
