    Research and Motion Analysis of Cutting Blade Mechanism of Copper Foil Shearing Machine by Ying Yueming

    Published 2015-01-01
    “…It is always a problem to improve the quality of copper foil shearing in PCB production.In order to research and develop copper foil shearing machine which has international competitiveness,taking the shearing mechanism of copper foil shearing machine designed by Rosenthal company in US as study object,the mechanism principle of shearing mechanism is descriped and the degree of freedom of mechanism is calculated.The motion analysis of shearing mechanism is carried out based on the methods of spatial mechanism kinematics and numerical calculation.Then,the analytic parameter formula of shearing mechanism cut point is deduced.The motion feature of shearing mechanism based on high speed and high cutting quality is proposed through the numerical experimentation and simulation experiment of shearing machine with 1500 copper foil breadth.The movement curve and controllable parameter which affects the performance of mechanism are obtained.The research contents can be taken as reference for the optimization of cutting blade mechanism design parameters.…”

    Video object segmentation by 2-D mesh-based motion analysis and morphological filtering by WANG Yu-jian, GAO Jian-po, WU Zhen-yang

    Published 2007-01-01
    “…A new temporal-spatial video object segmentation algorithm was proposed.This algorithm was based on 2-D mesh-based motion analysis and an improved spatial automatic segmenting strategy of morphological filtering.Firstly,higher order statistics was used for motion analysis of the 2-D mesh representation.After post-processing,relatively fine motion detection mask was quickly obtained.Then a novel watershed segmenting strategy based on alternating sequential filtering by reconstruction and adaptive threshold was applied to get the accurate boundary of the foreground object.Fi-nally,the video object was effectively extracted by fusing the temporal and spatial segmentation via region-based method.Experimental results indicate that the proposed algorithm assimilates the advantages of 2-D mesh-based algorithms and pixel-based algorithms,and achieves satisfactory subject and object performance.…”
