【摘要】：由于我國現(xiàn)在市場(chǎng)上微型揚(yáng)聲器組裝基本通過人工流水線作業(yè)方式進(jìn)行，但隨著人力成本的不斷提高，同時(shí)，競(jìng)爭日益激烈，客戶對(duì)于產(chǎn)品質(zhì)量的要求也不斷提高，在這種形勢(shì)下，進(jìn)行自動(dòng)化設(shè)備的研發(fā)制造尤為重要，同時(shí)對(duì)于提升我國裝備制造整體能力有重要意義。 本課題針對(duì)的是微型揚(yáng)聲器組裝過程中的壓合粘接工藝所需的自動(dòng)化壓合設(shè)備。對(duì)市場(chǎng)現(xiàn)有的手動(dòng)壓合裝置的結(jié)構(gòu)、工作原理、工藝等進(jìn)行了詳細(xì)分析研究，總結(jié)了手動(dòng)壓合裝置的不足和可取之處�；趶纳系较碌脑O(shè)計(jì)思想，采用模塊化設(shè)計(jì)方法結(jié)合差壓控制原理進(jìn)行了自動(dòng)化振膜壓合機(jī)的設(shè)計(jì)研究；利用ANSYS Workbench分析軟件對(duì)設(shè)備的關(guān)鍵部分——壓頭部分進(jìn)行了運(yùn)動(dòng)學(xué)仿真，得出了壓頭在接觸膠面瞬間的速度、加速度，對(duì)于控制系統(tǒng)的設(shè)計(jì)開發(fā)起到了很好的參考作用，大大縮短了設(shè)計(jì)周期，提高了設(shè)計(jì)效率。壓頭部件是整臺(tái)自動(dòng)化設(shè)備的關(guān)鍵所在，所以基于理論計(jì)算和仿真模擬的數(shù)值對(duì)壓力控制系統(tǒng)的壓力輸入設(shè)置不同的值，對(duì)壓合部件進(jìn)行了壓合試驗(yàn)，采集了壓合完成產(chǎn)品的幾何位置誤差數(shù)據(jù)，記錄了壓合時(shí)的壓力，，對(duì)試驗(yàn)數(shù)據(jù)及結(jié)果進(jìn)行詳細(xì)分析研究，找出壓力值和壓合結(jié)果的關(guān)系并對(duì)壓合部件進(jìn)行改進(jìn)設(shè)計(jì)；對(duì)改進(jìn)設(shè)計(jì)的壓合部件也進(jìn)行了壓合試驗(yàn)，結(jié)果表明，壓頭部件進(jìn)行改進(jìn)設(shè)計(jì)后，壓合的幾何精度有所提高，成品的良品率也提高了。本課題為小壓力的實(shí)現(xiàn)這一類自動(dòng)化設(shè)備設(shè)計(jì)問題提供了一定的參考價(jià)值。
[Abstract]:Since the assembly of micro loudspeakers in the market of our country is basically carried out by manual assembly line, but with the continuous increase of manpower cost and the increasingly fierce competition, customers' requirements for product quality are also increasing. In this situation, it is very important to develop and manufacture automation equipment, and to improve the overall capability of equipment manufacturing in China. This paper aims at the automatic pressing equipment for the bonding process of micro loudspeaker assembly. In this paper, the structure, working principle and technology of manual presser in market are analyzed and studied in detail, and the shortcomings and advantages of manual press device are summarized. Based on the top-down design idea, the modular design method combined with the differential pressure control principle is used to design and research the automatic diaphragm press machine, and the kinematics simulation of the key part of the equipment, the pressure head part, is carried out by using the ANSYS Workbench analysis software. The velocity and acceleration of the pressure head in the contact surface are obtained, which plays a good reference role in the design and development of the control system, greatly shortens the design cycle and improves the design efficiency. The pressure head part is the key of the whole automation equipment, so the pressure input of the pressure control system is set different values based on the theoretical calculation and the simulation value, and the compression test of the pressure control part is carried out. The geometric position error data of the finished product are collected, the pressure during compression is recorded, the test data and the results are analyzed and studied in detail, the relationship between the pressure value and the compression result is found out, and the compression parts are improved in design. The results show that the geometric precision of the pressing part is improved and the rate of the finished product is improved. This paper provides a certain reference value for the realization of small pressure automatic equipment design.
