【摘要】 论文介绍了微波炉灌封设备的工作原理，包括气路原理和液路原理。介绍了灌封设备的两种胶的比例调节机构、XY二维工作台、PLC控制的设计。比例调节采用的是摆杠运动调节的方案，实现了两种胶的准确的比例关系，并随着胶的不同而可以调节两种胶的比例，动力使用高压气体。XY二维工作台使用的是矩形贴塑导轨导向和承载，避免了在低速时的爬行现象。控制器采用了在工业控制中广泛采用的可编程控制器，另外还描述了步进电机的工作原理及其加减速控制。在灌封设备中还包括抽真空、自动控温、液位检测、自动清洗混合头等部分。文章还分析各种因素对XY二维工作台运动轨迹的影响，以及各种因素对出胶量的影响。在实际使用中满足现有微波炉的技术资料表明的技术要求和性能，运行可靠。更多还原

【Abstract】 This paper introduces the working principle of the pouring machine designed for the microwave oven,including the principle of flowing route of gas and liquid The designs of proportion-adjusting setup of pouring machine, XY planar worktable and PLC control are introduced in this paper. Swinging lever is used in the adjustment of proportion of two different kinds of glues .Exact proportion of the two kinds of glues is achieved and it can be altered according to different kinds of glues. High pressure gas is used as drive. XY planar worktable uses rectangle plastic-surface guideways for orientation and bearing the weight of worktable. As doing so ,it can avoid creep when guaidways is in low speed.Controller uses PLC, it is used widely in industry.Besides ,the principle of step motor and its acceleration and deceleration control are described. Pouring machine also includes parts of vaccumizing of glue tanks . controlling temperature automatically .measuring the location of the glues in the glue tanks and cleaning the mixer.The article also analyzes some facors which can catch effects on the XY planar worktable and some factors bearing on the weight of glues. In practice,pouring much -ine can work well and meet microwave oven’s demands in technic as its data shows更多还原
