摘要
机械装置结合计算机视觉技术可以对胡萝卜等细长型蔬果进行自动分级。为此,设计了胡萝卜自动分级机的机械装置部分,主要由双级匀果装置、链条辊轮输送装置和直线电机打果装置3部分组成。匀果装置通过带有隔板的交错格输送带和差速带对胡萝卜进行初次和二次匀果,实现精确单果输送;辊轮输送装置推动单个胡萝卜自转进入计算机视觉系统的CCD相机视场,可获得胡萝卜全面的形状特性,使其分级精确;直线电机打果装置接收到胡萝卜等级决策信号后将胡萝卜按不同等级经U型导管推入包装箱,推果平稳、快捷,伤果率低。
Mechanical devices combined with computer vision techniques can be used for automatic grading for carrots and other fruits and vegetables slim line .This paper designs the mechanical device of carrot intelligent grading machine , mainly composed of three parts： two-stage spacer device , chain roller conveyor and linear motors hit fruit devices . Spacer device with staggered grid via conveyor belt for carrots and differential for primary and secondary uniform fruit , and achieve precise single transport .The roller conveyor promotes single carrot rotating into a computer vision system CCD camera field , earn carrot shape comprehensive features that make precise classification .The linear motor , receiving the grading signal , puts carrots at different levels through the U-shaped catheter into the boxes , which pushes fruit smooth, fast, with low fruit injury .
