摘要本文研究的是电解阴极板矫直自动化系统。当前，电解阴极板大多采用人工矫直的办法，但人工矫直存在着矫直效率低、矫直精度差等诸多缺点。电解阴极板自动化矫直系统的开发可以有效解决这一问题，提高金属生产企业的生产效率。50293

矫直系统由矫直机械和控制系统组成。控制系统根据电解阴极板的原始弯曲曲率计算出相应的矫直参数，并控制矫直机械完成矫直任务。矫直参数的确定方法基于金属弹塑性变形理论以及压力矫直理论。矫直机械是实现矫直操作的基础，矫直机械的设计要能实现对阴极板的升降、夹紧、加载等矫直过程。控制系统是由图像采集模块、图像处理模块、PLC控制模块组成。首先由图像采集模块采集阴极板变形信息，经过处理转化成矫直参数，然后由PLC驱动伺服电机实现矫直过程。

Abstract

This study is the electrolytic cathode plate straightening automation system. Currently, electrolytic cathode plate mostly uses the artificial straightening. But there are many disadvantages of artificial straightening. The straightening efficiency and straightening precision is low. Development of electrolytic cathode plate automatic straightening system can effectively solve this problem, so as to improve enterprise metal production efficiency.

Composition of straightening system consists of straightening machine and control system. The control system based on the original curvature of electrolytic cathode plate to calculate the corresponding straightening parameters, and then, control the straightening machine to accomplish straightening task. Method for determining the straightening parameters based on metal elastic-plastic deformation theory and straightening theory. Straightening machine is the foundation of realizing the straightening operation. Design of straightening machine can realize lifting, clamping, loading on the cathode plate and straightening process. The control system is composed of image acquisition module, image processing module, PLC control module. Image acquisition module collects the cathode plate deformation information, then, translate into the straightening parameters. PLC control servo motor to realize the straightening process.
