摘要
在智慧农业的发展进程中,鲜果的无人采摘技术一直是制约其进步的关键因素。针对这一问题,基于激光切割技术的原理,以新鲜果蔬等的枝茎为研究对象,采用不同型号的激光器,并设置不同的工作模式对枸杞果梗进行精确切割。通过对比分析不同激光器对果梗切割效果的试验数据,对激光器在切割不同种类和成熟度的果梗时的性能进行综合评估。研究发现使用二氧化碳激光器进行鲜果切割具有最高的切割效率,使用24 W的二氧化碳激光器对直径约3 mm的新鲜树枝梗进行切割时,可以在15 ms内完成切割;对于直径1.5 mm的标准成熟枸杞果梗,可以在10 ms内完成切割,这对于需要快速处理大量果蔬采摘的农业工作人员来说至关重要。综合试验结果,建议使用30 W的二氧化碳激光器进行果梗切割,在确保切割效率的同时,还能确保枸杞等作物的外观完整性。
In the development process of smart agriculture,the unmanned picking technology of fresh fruit remains a critical challenge,limiting its advancement.In response to this issue,based on the principles of laser cutting technology,taking the branches and stems of fresh fruits and vegetables as the research objects,different types of lasers were used and different working modes were set to precisely cut the wolfberries fruit stalks.By comparing and analyzing the experimental data of the cutting effects of various lasers on fruit stalks,a comprehensive evaluation of the laser cutting performance on stalks of different fruit types and maturity levels was conducted.Research has found that using a carbon dioxide laser for fresh fruit cutting has the highest cutting efficiency.When using a 24 watt carbon dioxide laser to cut fresh branch stems with a diameter of about 3 mm,the cutting can be completed within 15 ms,for standard mature wolfberry fruit stems with a diameter of 1.5 mm,the cutting can be completed within 10 ms,which is very important for the agriculture that requires rapid processing of large quantities of fruit and vegetable.Ultimately,it is recommended to use a 30 W carbon dioxide laser for fruit stalk cutting,which can ensure cutting efficiency while also ensuring appearance integrity of crops such as wolfberries.
