摘　　要：为实现浇铸铜生产过程中浇铸模具位置及底面水平度的在线检测,设计制作了浇铸盘铜模平整度检测及定位测量装置。该装置由视觉系统检测、激光测距阵列及智能温控单元组成。视觉系统负责识别模具内边缘以确定模具位置;激光测距阵列用于测量模具底面采样点的高度,然后利用最小二乘法拟合平面算法确定模具底面水平度,并结合模具位置数据输出应调节高度。通过对实验数据的计算和对比,以及对现场浇铸完成铜板的测量验证,证明使用该方法能准确定位模具并能准确输出模具应调节高度,达到预期效果。In order to achieve online detection of the position and bottom levelness of the casting mold in the production of casting copper,a flatness detection and positioning measurement device for the casting disc copper mold was designed and manufactured.The device consists of visual system detection,laser ranging array,and intelligent temperature control unit.The visual system is responsible for identifying the inner edge of the mold to determine its position.The laser ranging array is used to measure the height of sampling points on the mold bottom,and then the least square method and plane algorithm are proposed to be used to determine the levelness of the mold bottom,and the desired height shall be outputted based on the mold position data.Through the calculation and comparison of test data,as well as the measurement verification of on-site copper plates casting,it has been proven that this method can accurately locate the mold and output the desired height of the mold,achieving the expected effect.
