本文係針對盲用點字印表機之主要機構進行設計與模擬分析。第一部份為設計新型盲用點字印表機之幾何模型,包括傳動機構、送紙機構與機殼;第二部份為模擬分析盲用點字印表機之傳動機構。傳動機構是盲用點字印表機的重要裝置之一,包含「步進馬達」帶動皮帶產生拉力;「橫桿」支撐點字頭座作橫向移動;「點字頭座」確保點字頭固定不至脫落;「點字衝擊桿」進行垂直方向撞擊運動。
在設計與模擬分析的流程上,本文係採用以參數式為設計理念,和全功能的機構設計自動化套裝軟體(Pro/E,Pro/Mechanica)為輔助。最後經由分析與模擬結果得知,傳動機構之點字頭座在承受皮帶最大拉力下所產生之應力和應變,均在彈性限範圍之內,對整個結構來說,不致發生影響,故此機構設計為一安全設計。
The design and simulative analysis of the Braille Printer are presented in this paper. The first, the transmittal mechanism, sending paper, and outer covering of a New Braille Printer are designed. The next, the combination of the shock shaft and socket of Braille head, transversal shaft, belt, and step motor in the transmittal mechanism are simulated and analyzed.
In the process of the design and simulative analysis, the (Pro/E , Pro/Mechanica)package is applied for its well-designed interface between the parameter design and mechanism simulation. After the simulation and analysis, the result of the Braille head socket of the transmittal mechanism sustaining the tensile indicates its strain and stress within the elastic scope. Thus the design of the new Braille printer is practicable.
