1 緒論
日常工作生活中，很多報告、材料或者網(wǎng)絡(luò)中查詢的資料，需要通過紙質(zhì)稿來存放，文件在保存時是離不開整理和裝訂的。因此文件的裝訂就顯得愈發(fā)重要，訂書機也逐漸成為了辦公用品中不可缺少的一部分。在一些大型文印中心要求能夠快速裝釘且整齊美觀，而普通訂書機無法滿足相關(guān)要求，此時就要有一種全新的訂書裝置來完成整理裝訂。可實現(xiàn)自動裝釘?shù)挠啎b置通過單片機控制，結(jié)構(gòu)穩(wěn)定，減輕了勞動強度，自動裝釘機構(gòu)提高了工作效率，可調(diào)節(jié)距離的裝訂盒可以滿足了不同大小紙張。
1.1 現(xiàn)有的訂書機功能對比
1.普通訂書機

圖1-1普通訂書機圖1-2重型訂書機
普通訂書機如圖1-1所示，是一種功能較為單一的訂書裝置，每次最大的裝訂數(shù)量大約為20張紙，且只能實現(xiàn)“一次一釘”，在裝訂的過程中容易出現(xiàn)裝釘不整齊，對于裝訂工作量較大的場合是非常不適用的。普通訂書機只能適合對裝釘要求不高、工作量小的辦公室。
2.重型訂書機
重型訂書機如圖1-2所示，是對上一種訂書機的優(yōu)化改進，它將普通訂書機的裝訂紙張數(shù)量擴大，裝訂紙張大于100張，大大的超過了普通訂書機，但相對而言，重型訂書機的功能相對單一，工作效率低，沒有解決裝訂不整齊等問題。于是產(chǎn)生了幾種裝訂整齊、便捷的訂書裝置...
