Device and method for mounting optical glass under vision guide

Abstract

The invention relates to a method and a device for mounting optical glass under vision guide. The method comprises the following steps of: acquiring images of the optical glass on a workbench at the same time by adopting two cameras arranged above the workbench; calculating a rough position of the vertex of the optical glass by adopting two sets of image processing algorithms in a computer respectively; acquiring the image of the optical glass through a camera arranged at the tail end of an industrial robot, and calculating the central position and the azimuth of the optical glass in the computer by adopting the image processing algorithm; and contacting a gripping device and four edges of the optical glass by adopting four vacuum sucking strips, adsorbing the optical glass from the workbench through an adsorption force, and placing the optical glass into a glass framework. The device comprises the industrial robot, an upper vision identifying unit, a front-end vision positioning unit and a control cabinet. The industrial robot faces the workbench on a zero-potential surface, and the glass framework is positioned on the rear side of the robot. The front-end vision camera can acquire the position of the glass framework.

Description

technical field [0001] The invention relates to an optical glass installation device and an installation method under visual guidance. Background technique [0002] The laser inertial confinement nuclear fusion experiment is one of the most cutting-edge research topics in the world. The experiment controls the laser amplification in stages, and finally forms a high-energy laser compression deuterium-tritium target implosion to achieve a controllable nuclear fusion reaction. In the laser inertial confinement fusion experiment, large optical glass is the working material and core material of the amplifier, which is mainly used in the main laser system as a power amplifier and multi-channel or main amplifier. Therefore, the installation quality of optical glass is crucial for laser systems and even fusion experiments. The quality of optical glass is relatively heavy (about 50 kg per piece), the cost is expensive, and it is required that no traces be left on the surface of the ...
