摘　　要：目的:解决鲜食玉米切割时准确率较低,随机误差较大,容易损伤籽粒问题。方法:设计了一种新型工艺的甜糯玉米加工生产线,该生产线利用机器视觉技术对玉米姿态进行判断,通过换向设备完成玉米姿态调整,设计适应性定位机构分别对玉米头尾进行切割,再依据切割后果穗苞叶附着力差异特点进行留层加工,经相机品质筛选后装箱,并利用样机进行加工试验。结果:该生产线加工效率达1 500穗/h;留层合格率为90.2%;籽粒破损率为1.81%。结论:该鲜食玉米加工生产线实现了玉米的上料、排序、切割、剥皮等工序自动化,实现苞叶合理留层,对比传统设备更加保护玉米籽粒。Objective:It solved the problem of low accuracy and large random error when cutting fresh corn,which is easy to damage the grain.Methods:A new process of sweet and waxy corn processing production line was designed,the production line used machine vision technology to judge the attitude of corn,completed the adjustment of corn attitude through reversing equipment,designed adaptive positioning structure to cut the head and tail of corn,and then carried out layer retention processing according to the difference characteristics of ear bract adhesion after cutting results,packed after camera quality screening,and used prototype to carry out processing tests.Results:The processing efficiency of the production line was up to 1500 spikes/h,the pass rate of retention layer was 90.2%,and the grain breakage rate was 1.81%.Conclusion:The fresh corn processing production line realizes the automation of corn feeding,sorting,cutting,peeling and other processes,realizes the reasonable retention of bracts and leaves,and protects corn grains more than traditional equipment.
