二、光电输入 1.提高光电输入的可靠性现在国内生产的数控线切割机床,穿孔纸带输入有两种方法。一种是电报头输入,速度慢,但比较可靠:另一种是光电输入,速度快,生产率高,但可靠性差。有些单位因光电输入可靠性差就不用了,使用人工输入或改用电报头输入。而我们用光电输入,一直比较稳定。为了提高生产率和产品质量,谈谈提高光电输入可靠性的体会。输入速度快,送数易出错。为了解决光电输入可靠性,起初我们注意了以下两点:(1)严格挑选晶体三极管和光敏二极管的参数;(2)对机械结构提出严格要求。如六
Second, the optical input 1. To improve the reliability of optical input Now produced in China CNC wire cutting machine, perforated tape input in two ways. One is telegraph input, slow, but more reliable: the other is a photoelectric input, high speed, high productivity, but poor reliability. Some units due to the poor reliability of the optical input, use manual input or switch to telegraph input. And we use photoelectric input, has been relatively stable. In order to improve productivity and product quality, talk about improving the reliability of optical input experience. Input speed, send error-prone. In order to solve the optoelectronic input reliability, at first we note the following two points: (1) rigorous selection of transistor and photodiode parameters; (2) the mechanical structure of the stringent requirements. Such as six
