電磁驅(qū)動點膠閥的工作特性分析與優(yōu)化研究 </p> <p> 點膠工藝***用于微電子、光電子、微機械系統(tǒng)等領(lǐng)域,而現(xiàn)有的點膠技術(shù)難以滿足口益復(fù)雜的封裝要求。噴射點膠是新一代的點膠技術(shù),但是現(xiàn)有的氣動——彈簧方式驅(qū)動的噴射點膠頭主要被國外公司壟斷,同時也存在驅(qū)動力有限,控制不方便等缺點。為打破壟斷,根據(jù)噴射點膠技術(shù)的要求,提出了電磁驅(qū)動噴射點膠方案。本文首先對點膠工藝和電磁驅(qū)動技術(shù)的發(fā)展現(xiàn)狀及趨勢做了簡要的介紹；接著介紹了電磁驅(qū)動噴射點膠技術(shù)的組成和實現(xiàn)原理,對其關(guān)鍵執(zhí)行元件電磁驅(qū)動噴射點膠頭的結(jié)構(gòu)設(shè)計過程進行了描述,完善了其結(jié)構(gòu)設(shè)計。根據(jù)電磁驅(qū)動噴射點膠的工作特點,設(shè)計、改進了驅(qū)動電路,對電路的工作原理和關(guān)鍵元件的選取做了詳細說明,并完成了電路的調(diào)試工作；然后對電磁噴射點膠頭試制樣品的進行了一系列的測試分析,包括預(yù)壓彈簧的剛度、靜態(tài)電磁力和噴針位移響應(yīng)等；同時,為了更好的分析電磁驅(qū)動噴射點膠頭的工作特性,利用Matlab/Simulink軟件建立了噴射過程的仿真模型。通過仿真模型,分析了驅(qū)動電壓、摩擦力等關(guān)鍵參數(shù)對噴射頭性能的影響,并進行了參數(shù)優(yōu)化,改進了噴射閥的性能。***,利用電磁驅(qū)動噴射點膠閥進行了噴射點膠實驗。

src="http://tyunfile.71360.com/UploadFile/qunxun/637219622716806640/6297711.png"></div><p> ⑴分析并確定了影響非接觸壓電式點膠閥正常噴射的主要因素----放大機構(gòu)的設(shè)計方案,并提出了放大機構(gòu)比較大輸出位移為320μm的設(shè)計目標；初步分析驗證了點膠閥閥針發(fā)生撓曲的可行性及必要性；在了解壓電陶瓷基礎(chǔ)理論的基礎(chǔ)上,運用有限元軟件ANSYS仿真分析所選壓電陶瓷的輸出位移與輸入電壓關(guān)系曲線,獲得200V時壓電陶瓷的比較大輸出位移為45μm,與實際測試結(jié)果基本相同,并且能滿足點膠閥對壓電陶瓷部件的位移要求。 </p> <p> ⑵通過ANSYS仿真,分析了放大機構(gòu)的輸出位移與拉緊螺栓預(yù)緊力F0、螺栓直徑D、三角塊長度L0、壓電陶瓷間距t等結(jié)構(gòu)參數(shù)之間的關(guān)系,并以優(yōu)化后的結(jié)構(gòu)參數(shù)D=2mm,Lo=2mm,t=10mm等尺寸設(shè)計樣機,實驗結(jié)果表明,樣機放大機構(gòu)的比較大輸出位移為320μm,滿足設(shè)計方案要求；放大機構(gòu)的輸出位移隨著施加電壓幅值的增大而增大,與占空比無關(guān)；當(dāng)驅(qū)動頻率為0～65Hz時,放大機構(gòu)的輸出位移基本保持在320μm左右,達到65Hz,將隨著頻率的增大而迅速減小。
