叠图机控制和驱动系统的研制

分析了叠图机原理，设计了叠图机控制和驱动系统．通过AT89C52单片机去控制步进电机转动，从而带动送纸胶辊和压纸胶辊按照规定尺寸进行叠图；设计了步进电机工作方式和相应的智能控制电路，其驱动电路使用IRF640等器件组成的大功率H桥式电路．系统实现了折叠多层图纸工作的自动化，不仅减轻了人工劳动，还提高了效率与叠图精度．

The Development for the Control and Drive System of Folding Machine

Based on the analysis of the folding machine principle, the control and driving system of a folding machine were designed. The stepper motor rotation was controlled by means of AT89C52, the sending paper rubber roll and the pressing paper rubber roll were driven in accordance with the required size folding. Both the stepper motor work methods and the corresponding intelligent control circuits were designed. A high-power H-bridge circuit of IRF640 was used to drive the circuit. The system realizes the automation of multi-folded drawings. It not only reduces the manufacturing labor, but also improves the efficiency and accuracy of folding machine.
