摘要:根据调查了解，随着科学技术的进步，社会的发展，办公自动化程度的提高，人们对办公设备的要求也越来越高，同时大量的文件需要盖章却让人们头痛，如何从繁琐的工作中解放劳动力，应用机器来代替人类劳动成为行之有效的方法。自动盖章机的研究具有了非常重要的作用和地位，特别是一些证件发放部门如行政机关，企业工厂，大专院校等常常需要完成大量文件和资料的盖章工作。而且目前均为手动盖章，不但操作强度大，效率低。虽然国内市面上出现自动盖钢印的机子，比如美国HEDMAN海德曼DI-100自动单页盖章机，但是很多时候我们不需要钢印，而是需要蘸印泥的章，国外有类似的设备，但是仍存在不足，如：只能应付小批量的文件，或者设备太大太昂贵，有些企业单位觉得性价比不划算，因此放弃使用，改用人工盖章，这样浪费很多时间和精力。针对上述情况，拟设计一种机电一体化的自动盖章机，实现自动盖章，其中工作频率和行程可调，能准确定位，自动计数，自动加印泥等。具有智能化，自动化，印痕清晰。均匀、稳定可靠、易于拆装和维修的特点，大大提高了自动化办公水平，有着非常重要的应用和推广价值。该装置现在已经向国家专利局申请专利保护（申请号：201220202833.2）。

　　　第一章首先介绍了本设计的选题目的及意义，阐述了自动盖章机的发展状况。然后根据手工盖章的过程，分析了可行的工作原理，并根据相关的工作原理设计出框架结构。

　　　第二章对系统功能进行描述，对功能进行分解，自动盖章机系统模块分解，最终求解得出系统设计方案并作出总布局图。

　　　第三章是本设计的主体部分。根据社会实践调查确定合理可行的设计要求参数，根据设计参数要求对每一个模块进行详细的设计。包括PLC自动控制系统设计，弹簧的设计，原动机的选择设计、联轴器的设计、轴的设计 、凸轮机构的选型与计算。 

　　　第四章对本次设计进行总结，简要说明本设计的优点和不足，并提出进一步研究的设想。

ABSTRACT:According to investigation, with the advances in science and technology, social development, the improvement in the level of office automation, office equipment requirements getting higher and higher, however, a large number of sealed documents allow people a headache, liberated from the tedious work of labor, the application machines to replace human labor to become an effective method. Automatic seal machine has a very important role and status of some documents issued sectors, such as administrative organs, enterprises, factories, universities, etc. are often required to complete a large number of documents and information sealed. And currently are manually stamped, not only the operating intensity and low efficiency. Domestic market to cover automatic stamp machine, but many times we do not need to stamp, but inks chapter, the foreign similar equipment, but there is still insufficient, such as: You can only cope with small quantities of documents, or equipment is too big too expensive, some business units feel that cost is not worth to give up in favor of artificial seal, so that waste a lot of time and effort. In response to these circumstances, intended to design a mechanical and electrical integration, automatic seal machines, automatic seal, which the operating frequency and stroke adjustable, accurate positioning, automatic counting, automatic ink pad. With intelligent, automated, clear prints. Uniform, stable and reliable, easy disassembly and maintenance features, and greatly increased the level of office automation, has a very important application and promotion of value.    The first chapter introduces the purpose and significance of the topics in this design, described the development of the automatic seal machine. Process and then hand-stamped, practical works, and frame structure designed according to the related works.    The second chapter is the main part of the design. Social practice survey to determine the reasonable and feasible design requirements parameters, according to the design parameters of the detailed design of each module. Including automatic seal machine system module decomposition, the choice of prime mover design, coupling, shaft design, selection and calculation of the cam mechanism, the final rack design and the overall assembly, and the precise design of some parts and calculations.Summary of Chapter III of this design, a brief description of the design strengths and weaknesses, and proposed the idea of further study.
