【摘要】: 汉字灯箱属于异型槽形字灯箱,是一种漂亮美观、节能省电的立体异形广告灯箱。异型槽形字灯箱以其独特的造型、亮丽的外观以及节省电力的LED照明灯光在欧美迅速流行开来,与普通的广告灯箱相比,它能给商家和店铺带来更为显著的广告效果,由此可以预见,在不久的将来,它也会在中国迅速流行开来。异型槽形字灯箱的制作材料主要为铝板,需要对铝板进行剪切加工,而汉字灯箱铝板数控剪齿机的主要功能是提取矢量汉字信息、拟合汉字轮廓,并根据轮廓的曲率、长度、拐角等参数自动在铝板上冲裁出锯齿口,以供制作立体槽型字灯箱之用。 本文主要介绍汉字灯箱铝板数控剪齿机的机构设计和软件系统的设计。在对数控剪齿机总体方案构思的基础上,首先介绍了矫直装置的矫直原理,设计方法和设计参数的计算选择,其次还介绍了冲裁机构、送料机构、切断机构的实现方法、设计计算以及要注意的事项,最后介绍了矢量汉字的存储结构和提取方法,以及加工信息的提取和生成。 剪齿机的机械部分主要有铝带卷支架、矫直机构、冲裁机构、送料辊、切断装置五部分组成,其中矫直机构的作用是整平拉直展开的铝卷,上矫直辊要做成可上下移动的,以适应不同的铝板,冲裁机构带有两个冲模,分别冲裁不同角度的缺口,送料机构和矫直机构一样要做成可上下移动的。 软件系统主要是提取矢量汉字信息,电脑系统中矢量汉字是以关键点来存储的,这就需要利用Bezier曲线拟合汉字轮廓。拟合轮廓后计算每个闭合轮廓上线段的长度、曲率来获得加工信息。
[Abstract]:The Chinese character lamp box belongs to the special shape slot shape word light box, is a kind of beautiful and beautiful, energy saving and energy saving stereoscopic special advertisement light box. With its unique shape, bright appearance and electric power saving LED lighting, the special-shaped slot type light box becomes popular in Europe and the United States. Compared with ordinary advertising light box, it can bring more remarkable advertising effect to merchants and shops. It can be predicted that in the near future, it will also quickly become popular in China. The manufacturing material of the special shaped slot type light box is mainly aluminum plate, which needs to be cut and processed. The main function of the CNC cutting machine of Chinese character light box aluminum plate is to extract the vector Chinese character information, fit the Chinese character outline, and according to the curvature and length of the contour, the main function of the CNC cutter is to extract the vector Chinese character information, and to fit the outline of the Chinese character. Corner and other parameters automatically cut out the sawtooth on the aluminum plate for the production of three-dimensional groove type light box. This paper mainly introduces the mechanism design and software system design of CNC cutting machine for aluminium plate of Chinese character light box. On the basis of the conception of the overall scheme of the NC cutter, the straightening principle, the design method and the calculation selection of the design parameters of the straightening device are introduced, and the realization method of the blanking mechanism, the feeding mechanism and the cutting mechanism are also introduced. Finally, the storage structure and extraction method of vector Chinese characters, as well as the extraction and generation of processing information are introduced. The mechanical part of the shearing machine mainly consists of five parts: aluminum tape coil bracket, straightening mechanism, punching mechanism, feeding roller, and cutting device. The function of the straightening mechanism is to straighten out the aluminum coil, and the upper straightening roller should be made up and down movable. In order to adapt to different aluminum plates, the punching mechanism has two punching dies and punches the notches at different angles respectively. The feeding mechanism and the straightening mechanism should be made to move up and down. The software system is mainly to extract the vector Chinese character information, and the vector Chinese character is stored in the computer system by the key points, so it is necessary to fit the outline of the Chinese character by using the Bezier curve. After fitting the contour, the length and curvature of the line segment on each closed contour are calculated to obtain machining information.
