基于PLC的镍电解始极片加工机组全自动控制系统

镍电解始极片全自动加工机组的控制系统采用PLC控制，在控制系统中结合各种行程开关、光电开关、传感器和电磁阀实现各机构的行程、运动控制和机组的电、液、气控制。在机组中，由于动作要求（频繁的正反转或起停动作）而使用步进电机的机构，如滑车的运动、阴极板输送和提升机构的运动，皆不能由异步电机代替。在步进电机的控制上，采用专用的步进电机驱动器控制。气压和液压系统的控制采用电磁换向阀、单向阀、溢流阀、单向节流阀等液、气压元件进行控制。主要内容包括选择控制方案，设计电气系统，以及PLC程序设计。除此以外，对冲铆机结构三维设计，以及自动放棒装置原理分析、方案拟定，均作了相应的介绍。

The nickel electrolysis cathode boards automatic process cathode board, the core adopts the Programmable Controllers, going together with inputting order of buttons, route of travel switch and Output after the electric appliances to complete all controls. The kinetic system mainly adopts liquid pressure, air pressure and electric motor. Among them, the liquid presses urn and the air pres- ses urn of sports use electromagnetism valve to control. The main contents includes the choice control project,design electricity system and PLC program design. Excluding, to the hurtling and riveting of machine three stereoscopic construction design, and putting auto- matically stick equipment of principle analysis, the project drafts, all make the homologous introduction.
