A Laser Automatic Positioning System of Electron-gun for High-resolution Colortron Seal-machine

In this paper, a laser automatic positioning alignment system is presented which position the electron gun relating to the screen. This system consists of laser, laser collimating, a sensor, a controlling system of single chip microcomputer, driving circuit and special reducer. Under the control of single chip microcomputer, it completes the locating of electron gun automatically. The simulated experiment shows that this system completely position the electron-gun in the rang of positioning precision.
