【摘要】：烹饪机器人的出现使自动化烹饪成为现实,符合科技及生活现代化的发展趋势。十多年来,中餐烹饪机器人在功能上有了许多改进和增加,但是调料添加方面却始终没有突破,一直止步于液态调料的添加。本文从固态粉末状调料添加入手,对调料的一些基本特性进行了研究,为系统的机械结构设计打下了理论基础。分析了烹饪机器人对粉末调料添加系统在结构及功能等方面的实际需求,对比了几种常见的粉料的输送和计量方式及应用特点,提出了一种并联四个立式螺杆下料机构形成的下料解决方案。方案采用两个电机作为整个系统的下料动力源与搅拌动力源,利用微小型电磁离合器作为连接分下料器与电机的开关,实现了一个动力源控制多个分下料机构工作的重要功能。在基于Matlab优化工具箱及Inventor三维设计软件的辅助下,对下料螺杆及投料机构进行了结构优化设计。在传统螺杆输料理论的基础上,详细分析了螺杆向下输料机构中的物料运动原理及特点,提出了容积计量法的修正公式。在相关学者的实验数据的基础上,对散料堆积密度变化规律进行了研究。根据压实实验的特点提出了物料等质量分层法,建立了物料堆积密度与堆积深度关系的数学模型,并对修正后的容积计量法的实际应用提供了计算思想及方法。
[Abstract]:The appearance of cooking robot makes automatic cooking become a reality, in line with the development trend of science and technology and life modernization. For more than a decade, the Chinese cooking robot has made a lot of improvement and increase in its function, but there has been no breakthrough in the addition of seasoning, which has been stopped at the addition of liquid condiments. In this paper, starting with the solid powder seasoning, some basic characteristics of the seasoning are studied, which lays a theoretical foundation for the mechanical structure design of the system. This paper analyzes the actual demand of cooking robot for powder seasoning system in structure and function, and compares several common conveying and metering methods of powder and its application characteristics. In this paper, a method of shedding in parallel with four vertical screw blanking mechanisms is presented. In the scheme, two motors are used as the power source of the whole system, and the micro electromagnetic clutch is used as the switch to connect the discharger and the motor. The important function of one power source to control the work of the multiple shedding mechanism is realized. Based on the aid of Matlab optimization toolbox and Inventor 3D design software, the structure optimization design of feed screw and feeding mechanism was carried out. On the basis of traditional screw feeding theory, the principle and characteristics of material movement in screw downward feeding mechanism are analyzed in detail, and the modified formula of volumetric method is put forward. Based on the experimental data, the variation of bulk density is studied. According to the characteristics of compaction experiment, the material equal mass stratification method is put forward, and the mathematical model of the relationship between material packing density and packing depth is established, and the calculation idea and method are provided for the practical application of the modified volumetric method.
