| 目的 为了满足现代工业领域中对轻、薄、小产品平稳输送的要求，设计一种利用压电双晶片振子惯性力作为驱动源的新型直线式振动送料器。方法 在对振动送料器的工作原理进行分析的基础上，建立压电振子动力学模型，利用Matlab软件分析振子长度和质量对冲击力与变形量的影响，研制送料器样机并进行性能测试。结果 当振动频率为209.5~214.5 Hz时，送料器具备输送物料的能力；当系统共振时，输送速度最快，随着电压的增加，送料速度呈线性关系增加。结论 与同型号的电磁振动送料器相比，研制的压电直线式振动送料器消耗电流仅为其14%，工作噪音下降了17 dB。与同型号日本压电送料器相比，输送速度提高了10%。 |

| The work aims to design a new-type vibratory feeder driven by inertia force of piezoelectric bimorph vibrator to meet the conveying requirements on light, thin and small product in modern industry. Based on the analysis of the working principle of the vibratory feeder, the dynamic model of the piezoelectric vibrator was established. The influence of the length and mass of vibrator on the impact force and deformation were analyzed with Matlab software. A prototype of the vibratory feeder was produced and its performance was tested. The feeder was capable of conveying part when the vibration frequency was 209.5-214.5 Hz and could reach the maximum feeding rate at resonant frequency. The feeding rate increased linearly with the increase of the voltage. Comparing with the electromagnetic vibratory feeder, the current consumption of such new linear vibratory feeder is only 14% and the noise is reduced by 17 dB. Comparing with the made-in-Japan piezoelectric vibratory feeder, the transmission speed has been raised by 10%. |
