The Design And The Experimental Research Of The Z Style Spring Piece Of Piezoelectricity Vibration Feeder

The Z style spring piece of piezoelectricity vibration feeder is a new type of the vibration feeder,compared to the traditional vibration feeders,this type have a lot of advantage. For example, wide range of feeder rates ,high reliability and stability, no heat, no magnetic effect,energy-saving and so on. The Z style spring piece of piezoelectricity vibration feeder is more easier to be changed by the aspect of angle. Because of this ability,it is have a great value in production practise.This article has used Piezoelectric bimorphs as the piezoelectric vibration feeders actuation source and made two piezoelectric vibration feeders example mechanism by myself. And we tested it. The result indicates homemade feeder can work stably and stand . Moreover has the structure simply, disassembles and assembles conveniently,feeds steadily and fast, the noise is small and so on the merits.The paper consists of six chapters,given as follows:Chapter 1 IntroductionAlong with advanced manufacture technology rapid development, product's automatization and integration is more and more higher,vibration feeder has very important application significance on some field as industry ,agriculture and military affairs .First of all the paper expatiate the research signification and The Z style spring piece of piezoelectricity vibration feeder's advantages compared to the traditional vibration feeders,and then a review about the research emphasis and research results of piezoelectric vibration feeders at broad and home is given, The main research content of the paper is list at last.Chapter 2 Piezoelectric bimorphsThis article designs horizontally pushes type piezoelectricity vibration feeder is carries on the actuation using the piezoelectricity ceramics counter piezoelectric effect .So this chapter mainly introduces the concept of piezoelectricity effect and converse piezoelectricity effect, This part introduces the types of piezoelectric bimorphs and support way. The theoretical analysis and experiment having been in progress to piezoelectric bimorphs study. The main conclusion:When the vibrator imports static state voltage to two piezoelectric wafer, the amounts of exporting displacement and import static state voltage becomes the linearity relation enhancing, While the vibrator exerts sine alternating voltage to two piezoelectric wafer, may simple harmonic vibration happened in the two piezoelectric wafer vibrator , amplitude enhances also with the voltage power-up linearity, and the maximal knot of amplitude reasons with in whose syntony frequency.Chapter 3 Structure design and working theory of the angle of the spring piece by the piezoelectric vibration feederThis section we anlysis the effect of change the angle of the spring piece by the piezoelectric vibration feeder could change the performance of vibrator feeder. And with this conclusion we designde the structure and components of two different angle of vertical piezoelectric vibration feeder. It analyze working theory of vertical piezoelectric vibration feeder and movement state of the parts.Chapter 4 FEM analysis of the piezoelectric feeder which with the Z spring pieceThis section designs the structure and components of piezoelectric vibration feeder,make it and assemble two example machines. It Elaboration working theory of piezoelectric vibration feeder and Work process,analyze movement state of the parts.Chapter 5 Experimental analysis of piezoelectric feederBased Orthogonal experiment theory, we establish four factors and three level experimental table. We can get the most excellent combination which effect the feeder capability from the analysis of experiment results used the method of R. Then we choose the most excellent combination to do single experiment and can get a series of connection curve between different factors and frequency, voltage and feeder rates, voltage and amplitude, frequency and feeder rates, amplitude and feeder rates etc.Chapter 6 Conclusion and expectationThe chapter gives the main conclusion obtained form this paper and the prospect for next research.
