Method and device for measuring position and line width of laser beam by using line array CCD (Charge Coupled Device)

InactiveCN102062579AUsing optical meansLine widthLaser beams

The invention relates to a method and device for measuring position and line width of a laser beam by using a line array CCD (Charge Coupled Device). The method comprises the following steps of: 1, obtaining a Gaussian curve of an incident laser line beam; and 2, detecting the position and the line width of the laser beam according to the Gaussian curve. The method and the device can be used for detecting the absolute and the relative positions of the laser line beam and detecting the line width of the line beam, and can be converted into a mode of measuring displacement, length, angle displacement and the like; and by using the method, the deformation and the amplitude of a platform are detected, the line linearity of the straight line laser is measured, and a laser instrument is comprehensively detected.

Plate leveling method for plate jointing operation in shipbuilding plane section assembly line

InactiveCN103192953AEasy to judgeEasy to operateVessel partsAssembly lineEngineering

The invention provides a plate leveling method for plate jointing operation in a shipbuilding plane section assembly line. The plate leveling method comprises the following steps of: adopting a linear laser in the plate jointing operation; transmitting laser lines at an angle of 40-45 degrees formed by the linear laser and the horizontal direction for simultaneously projecting plate surfaces with different heights, wherein if the heights of the plate surfaces are different, intersection points of the laser lines reaching the plate surface are different, and if the heights of the plate surfaces are identical, intersection points of the laser lines reaching the plate surfaces are identical; and adjusting the levelness of the joined plate according to information of the intersection points. According to the plate leveling method disclosed by the invention, the problems of lower work efficiency and longer consumed time in the plate jointing work in the prior art can be solved; information judgment of operators is visual, so that the accuracy of the operation position of the plate can be achieved quickly and effectively; and the time consumed by assembling and positioning operation quantity of same weld joints is shortened by 50 percent compared with the prior time, and thus the work efficiency of jointing plate is greatly increased.
