目的 基于慧鱼技术设计一套餐盘分拣系统，旨在自动分拣盘子、餐盘和勺筷，节省人工成本，提高工作效率，并证明慧鱼模型在创新培训中的实用性与优势，培养学生的自主创新意识和解决工程问题的能力。方法 设计餐盘分拣系统的碗分离、勺筷分离、盘分离等机构，用慧鱼创意组合模型搭建餐盘分拣系统的实物模型。采用威纶触摸屏作为上位机，西门子S7-200PLC作为下位机的控制方式开发餐盘分拣系统的控制程序。结果 实验结果表明，该餐盘分拣系统分拣效率较高，能实现多种餐具的自动分拣，提高了工作效率。结论 该餐盘分拣系统实现了餐盘里碗、盘、筷子、金属勺模型的成功分离和按类收集，可用于机械课堂教学和PLC课程的实验教学设备，同时对于现实生产具有实际的推广意义。

The work aims to design a tray sorting system based on the Fischertechnik, aiming at automatic sorting of plates, trays, spoons and chopsticks, saving labor costs and improving work efficiency, and demonstrating the practicality and advantages of the Fischertechnik model in the innovative training, and cultivating students' awareness of independent innovation and their ability to solve engineering problems. The mechanisms of bowl separation, spoon and chopstick sep-aration and plate separation in the tray sorting system were designed. The Fischertechnik model was used to construct the physical model of the tray sorting system. The Weilun touch screen was used as the upper computer, and the Siemens S7-200PLC was used as the control method of the lower computer to develop the control program of the tray sorting system. The experimental results showed that, the tray sorting system had high sorting efficiency and could realize automatic sorting of a variety of tableware, which improved work efficiency. The tray sorting system successfully separates the models of bowls, plates, chopsticks and metal spoons in the trays and collects them by type. It can be used as the experimental teaching equipment in mechanical classroom teaching and PLC courses, and has practical promotion significance for practical production.
