激光光幕式压力机械光电保护装置的研究

Study onlaserlight-screen-typeopto-electronic protective device for pressing machine

以激光束形成光幕为压力机械提供一种光电安全保护装置。这种以Ｈｅ－Ｎｅ激光束形成的光幕配以相应的电子电气元件构成的安全保护装置，简单可靠。。实现了保护高度４００ｍｍ，长度６ｍ，光轴间距３０ｍｍ的灵敏区，及稳定的安全保护功能。

For a pressing machine,an opto-electronic protective device is provided,using light-screen formed by the laser beam.The protective device,composed of the light-screen formed by He-Ne laser beam and relevant electronic elements,is simple and reliable. The protective height is 400mm,length is 6m and the sensitive distance of optical axes is 30mm.It has stable protective function.
