本论文选取包装生产线上产品的自动装箱这个环节为研究对象,通过两条包装及产品传送带的传送完成。选用AT89C52单片机为核心,通过用8255A扩展I/O实现键盘及显示、报警、检测功能。首先在键盘输入数值,采用四位LED显示并通过控制两台伺服电机的运动,将产品送入纸箱并包装然后运走。其系统的关键是在包装箱到达的时刻,检测器能准确的输入信号使传送带能在纸箱刚好到达产品传送带的同时停止,并能在装满的同时将空箱及时
This thesis chooses the automatic packing of products on the packaging line as the research object and completes the transmission through two packages and the product conveyor belt. Select AT89C52 microcontroller as the core, through the use of 8255A expansion I / O keyboard and display, alarm, detection. First enter the value on the keyboard, using four LED display and by controlling the movement of two servo motors, the product into the carton and packaging and then shipped away. The key to the system is that when the box arrives, the detector can accurately input the signal so that the conveyor can stop just when the carton reaches the product conveyor belt, and can empty the box in time
