【摘要】：超高速背板是互聯(lián)網(wǎng)骨干網(wǎng)絡(luò)中節(jié)點設(shè)備的關(guān)鍵部件之一,壓配合連接器的壓接工序是超高速背板加工產(chǎn)業(yè)中很重要的環(huán)節(jié)。面對高速、高密集型壓配合連接器的快速發(fā)展,背板加工行業(yè)對連接器壓接設(shè)備的定位精度,可靠性,柔性化和自動化程度提出了更高的要求。因此本課題針對壓配合連接器自動壓接設(shè)備的機械系統(tǒng)進行了設(shè)計、分析及優(yōu)化。本文基于自動壓接工藝需求,設(shè)計了能承受較大負載的,高剛性的,同時具備較高定位精度的柔性化的自動壓接設(shè)備,對進一步推動連接器壓接設(shè)備的發(fā)展有一定意義。本文首先介紹了連接器的壓接工藝特點,全面分析了壓接設(shè)備的國內(nèi)外發(fā)展現(xiàn)狀,并對目前最先進的自動化壓接設(shè)備所使用的的直角坐標(biāo)系機械結(jié)構(gòu)的研究現(xiàn)狀進行了分析和探討。在結(jié)構(gòu)設(shè)計階段,采用了直角坐標(biāo)系框架作為機械系統(tǒng)的主體結(jié)構(gòu),選用了直線電機驅(qū)動X、Y軸,選用了伺服電機驅(qū)動Z軸,并通過建模軟件PRO/E建立了三維模型草圖。在機械結(jié)構(gòu)校核驗證方面,使用了有限元分析軟件對設(shè)備的橫梁、立柱等關(guān)鍵結(jié)構(gòu)進行了靜力學(xué)分析和模態(tài)分析,并使用類比法對結(jié)構(gòu)進行了優(yōu)化設(shè)計,最終提升了機臺的剛度和固有頻率。還利用了虛擬樣機技術(shù)對機構(gòu)進行了運動仿真,驗證了驅(qū)動部件的理論計算結(jié)果的正確性。最后,在上述研究的基礎(chǔ)上建造了一臺全自動壓接設(shè)備,并對整機進行了定位精度校驗和自動壓接連接器實驗。通過相關(guān)實驗,驗證了有限元分析和運動仿真的準(zhǔn)確性。
[Abstract]:Ultra-high speed backplane is one of the key components of node equipment in Internet backbone network. The pressing process of press fit connector is an important link in ultra-high speed backplane processing industry. Facing the rapid development of high-speed and high-intensive press fit connectors, the backplane processing industry has put forward higher requirements for the positioning accuracy, reliability, flexibility and automation of the connector pressing equipment. Therefore, this paper designs, analyzes and optimizes the mechanical system of automatic press joint equipment for press fit connector. Based on the requirement of automatic pressing process, this paper designs flexible automatic pressing equipment which can bear large load, high rigidity and high positioning precision, which is of certain significance to further promote the development of connector pressing equipment. In this paper, the characteristics of the connector pressing process are introduced, and the development status of the press joint equipment at home and abroad is analyzed. The research status of the Cartesian coordinate system used in the most advanced automatic pressing equipment is analyzed and discussed. In the stage of structure design, the frame of Cartesian coordinate system is adopted as the main structure of the mechanical system, the linear motor drives the XY axis, the servo motor drives the Z axis, and the 3D model sketch is established by the modeling software PRO/E. In the aspect of mechanical structure checking and verification, the finite element analysis software is used to carry out the static analysis and modal analysis of the key structures, such as the beam and column of the equipment, and the optimization design of the structure is carried out by using the analogy method. Finally, the stiffness and natural frequency of the machine are improved. The virtual prototyping technology is also used to simulate the motion of the mechanism, which verifies the correctness of the theoretical calculation results of the driving parts. Finally, on the basis of the above research, a fully automatic bonding equipment is built, and the positioning accuracy check and the automatic pressing connector experiment are carried out on the whole machine. The accuracy of finite element analysis and motion simulation is verified by relevant experiments.
