摘要
为了适应汽车焊装生产线柔性化的控制要求,以一个自动焊枪在2个焊点之间运动的动作程序为例具体讨论了PLC控制系统的硬件与软件设计,给出了系统的梯形图及PLC输入/输出地址对照表。将PLC应用于汽车焊装生产线的控制系统中,改变了传统的继电-接触器控制,使得控制更加灵活,设备运行更加可靠,在不改变硬件接线的条件下,通过改变程序就可改变生产工艺。
For adapt to automobile welding production line flexible control requirements,Take one gun at two points welding process for exemplification, discussing the hardware design and software configuration of the control system, and Given the ladder diagram of the system and the PLC I/O list.Programmable controller used in automobile welding production line will replace the traditional control function with relay and contac- tor. The control and operation will be smart and reliable. Fixedly the circuit connection, rely on change the program be able to alter the procedures.
