本文介绍了把一台分立元件自动冲槽机控制器改为使用M0S集成电路的控制器的研制工作.主要工作是:据据MOS电路的特点设计了逻辑总图;设计和试验了合适可靠的拖板延时复位电路,单稳电路及功率驱动电路;装制了体积较小的控制器;“控制器”连续工作表明是稳定可靠的.一、概述现在的硅钢片冲槽机,大多数还是人工操作的,这不但效率低,也不安全.1977年初,我们参考了湘潭电机厂的晶体管自动冲槽机控制器的设想思想,根据我室生产的六种型号的MOS集成电路,设计和制造了MOS自动冲槽机控制器.该控制器是整个自动冲槽机的电子控制部分.它控制和协调冲槽机和机械手的工作,自动完成冲片上料,冲槽,下料等工作.实现了冲槽工序的自动化.控制器的基本设计思想是:按冲槽过程中各机械部件的动作次序及配合协调的要求,将动作分为若干个程序步(本机分为十个程序步),每个程序步完成一个或几个简单的机械动作,根据动作的时间长短,给每个程序步予置一定的时间,该时间一到则自动转到下一个程序步,每个程序步所发出的讯号由“记忆部件”记忆下来,并经功率门去控制继电器的吸合,从而控制各机械部件的动作.此外,为了保证冲槽机的动作的正确可靠和便于监视,还设置了显示部件、校验部件、互锁连锁电路以及报警系
This paper introduces the research and development of a controller that uses a single-component automatic notching machine instead of a M0S integrated circuit. The main tasks are: Designing a logic master map according to the characteristics of a MOS circuit; Designing and testing a suitable and reliable Delay circuit reset circuit, monostable circuit and power drive circuit; installed a smaller controller; “controller” continuous work shows that is stable and reliable. I. Overview Now silicon steel slotting machine, the majority of Or manual, which is not only inefficient, but also not safe.In early 1977, we refer to the Xiangtan Electric Works transistor transistor notching controller ideas, according to my room produced six types of MOS integrated circuits, design and Manufactured the MOS controller, which is the electronic control part of the whole automatic notching machine, which controls and coordinates the operation of notching machine and manipulator, and automatically finishes the work such as feeding, notching and blanking. Which realizes the automation of notching process.The basic design idea of the controller is that the action is divided into a number of steps according to the sequence of the action of each mechanical part in the process of notching and the requirements of coordination and coordination Step), each program step to complete one or a few simple mechanical action, according to the length of time for the action, give each program step to set a certain time, the time to automatically go to the next step, each The signal sent by the program step is memorized by the “memory part” and controlled by the power gate to control the pull-in of the relay, so as to control the actions of various mechanical parts. In addition, in order to ensure the correct and reliable operation of the notching machine and to facilitate the monitoring Set the display components, calibration components, interlocking chain circuit and alarm system
