【摘要】：氣旋式非接觸真空吸盤作為一種新興的氣動執(zhí)行元件,可以在對工件進行吸取和搬運的時候與工件保持非接觸狀態(tài)。因此它具有對被吸工件非接觸、無損傷、無污染等優(yōu)點,在制藥、半導(dǎo)體等對工件要求無損和高潔凈度的行業(yè)具有迫切而廣泛的應(yīng)用需求。 雖然國際上已有此方面的文獻(xiàn)報道,然而由于技術(shù)封鎖,對氣旋式非接觸真空吸盤還沒有公開的設(shè)計方法和理論可以應(yīng)用。因此,要打破技術(shù)封鎖,盡快研究出自己的氣旋式真空吸取技術(shù),需要對氣旋式真空吸取的吸力產(chǎn)生機理、吸盤結(jié)構(gòu)設(shè)計、動態(tài)工作特性和系統(tǒng)集成等多方面進行深入研究。 通過理論分析、試驗測試和系統(tǒng)實現(xiàn)等研究工作,本文取得了以下一些研究成果： (1)針對氣旋式非接觸真空吸盤真空吸力產(chǎn)生和調(diào)節(jié)的機理性分析需要,采用Fluent軟件對吸盤內(nèi)部流場進行了數(shù)值模擬,獲得了吸盤內(nèi)部強旋回流流動的流場分布規(guī)律以及吸盤工作參數(shù)對吸取力的影響,為吸盤的結(jié)構(gòu)設(shè)計和性能測試打下了基礎(chǔ)。 (2)構(gòu)建了吸盤性能綜合試驗系統(tǒng),對數(shù)值分析所獲得的流場分布規(guī)律進行了試驗驗證。試驗研究了吸盤工作參數(shù)對吸力和工作動態(tài)過程的影響,獲知影響吸取過程的主要因素是供氣流量和吸取時初始間隙。得出為了減小工件振動,應(yīng)盡量減小初始間隙并采用“先大后小”的流量控制原則,以及為避免扭轉(zhuǎn)效應(yīng),氣旋式非接觸吸盤應(yīng)多個成對使用的原則。這些結(jié)果對于氣旋式非接觸真空吸盤及其系統(tǒng)設(shè)計和操作具有非常重要的參考價值。 (3)設(shè)計了一個實際的氣旋式非接觸真空搬運系統(tǒng),驗證了氣旋式真空吸盤的機理分析和試驗研究成果,獲得了氣旋式非接觸真空搬運系統(tǒng)的設(shè)計和應(yīng)用的寶貴經(jīng)驗。
[Abstract]:As a new kind of pneumatic actuator, cyclone vacuum sucker can keep non-contact state with the workpiece when it is absorbed and moved. Therefore, it has the advantages of non-contact, no damage and no pollution to the absorbed workpiece, so it has an urgent and extensive application demand in pharmaceutical, semiconductor and other industries which require non-destructive and high cleanliness of the workpiece. Although this aspect has been reported in the international literature, however, due to the technical blockade, there is no open design method and theory of cyclone non-contact vacuum sucker can be applied. Therefore, in order to break the technical blockade and develop the cyclone vacuum suction technology as soon as possible, it is necessary to deeply study the mechanism of suction, the structure design of sucker, the dynamic working characteristics and the system integration. Through theoretical analysis, experimental testing and system implementation, this paper has achieved the following research results: 1) to meet the need of mechanical analysis on the generation and regulation of vacuum suction of cyclone type non-contact vacuum sucker, a numerical simulation of the internal flow field of the sucker is carried out by using Fluent software. The distribution of the flow field and the influence of the working parameters of the sucker on the suction force were obtained, which laid a foundation for the structure design and performance test of the sucker. (2) A comprehensive test system for the performance of the sucker is constructed, and the flow field distribution law obtained by the numerical analysis is verified experimentally. The influence of the working parameters of the sucker on the suction force and the working dynamic process is studied. The main factors affecting the suction process are the gas supply flow rate and the initial clearance of the suction process. It is concluded that in order to reduce the vibration of the workpiece, the initial gap should be reduced as much as possible and the flow control principle of "first big and then small" should be adopted, and in order to avoid torsional effect, the cyclonic non-contact chuck should be used in pairs. These results have very important reference value for the design and operation of cyclone type non-contact vacuum sucker and its system. A practical non-contact vacuum transport system is designed, which verifies the mechanism analysis and experimental research results of cyclone vacuum chuck, and obtains valuable experience in the design and application of cyclone non-contact vacuum transport system.
