摘要
为了使液晶屏压合器在使用过程中能够平稳、快速、准确地完成液晶屏与机体后壳的压合动作,设计了一种步进电机控制器。该系统采用单片机S3FN41F作为微处理器,通过PC机上的人机交换界面与单片机进行CAN通信。单片机产生脉冲信号,以驱动硬件控制电路,从而完成对步进电机的控制。该系统不仅可以进行离线控制,还可以通过PC机进行在线调试,具有稳定性高、响应速度快、体积小、安装调试方便等优点,能够广泛应用在压合系统中,具有实际推广意义。
In order to ensure that the lamination action for LCD and the back shell of electronic device can be steadily,rapidly and accuratelyduring the working process of lamination machine of LCD, a stepper motor controller is designed. The system adopts single chip computerS3FN41F as microcontroller, completes CAN communication between single chip computer and PC though the human - machine interface. Andgenerated pulses of single chip computer drives hardware control circuit to control the stepper motor. The system can be off line controlled andonline debugged through the PC. It features many advantages, such as great stability, fast response speed, compact, ease installation anddebugging,thus it can be widely applied in lamination system,and promoted in practical applications.
