Design of Automatic Sale of the Machine Based on 51 Microcontrollers

该文阐述了一种基于51单片机的自动取餐机器,降低了劳动力成本,提高了餐厅的售餐的高效性。自动售餐机由电动机输出额定转速,通过链传动带动主动轴承旋转,皮带轮在轴承驱动下带动两条同步带匀速运动,同步带间置有定位餐盘的支架,实现餐盘的往复运动,光电开关控制餐盘的停转。自动售餐机底部置有红外线灯管,定时间隔对往复运动到底部的餐盘进行加热,达到保温效果。取餐口置有紫外线灯管,只在取餐时对内部环境进行消毒。

This paper elaborates a kind of automatic sale of the machine based on51microcontrollers which greatly reduces the labor cost and improves the efficiency of the restaurant.The rated speed of the automatic sale of the machine is outputd by the motor driving active bearings for rotary motion through chain drive.The pulley drives two synchronized belts with uniform motion under the bearing drive.The timing belt is equipped with a bracket for positioning the tray to achieve the reciprocating motion of the tray and the meal is stopped by the photoelectric switch.The infrared light tube which is at the bottom of the automatic sale of the machine heat the plate reciprocating to the bottom by interval time to achieve insulation and sterilization effect.There is an ultraviolet lamp in the mouth of the meal which disinfect the Internal environment only when taking a meal.
