基于激光扫描的球压试验压痕直径自动测量系统研制及应用
Development and application of an automatic measurement system for indentation diameter in ball pressure test based on laser scanning
摘要
Abstract
During the ball pressure test for electrical and electronic products,the traditional indentation measurement method is not easy to accurately distinguish the boundary between indentation and material thermal deformation,which is prone to cause large deviations in measurement results.Additionally,the measurement of ball pressure test is limited by short measurement time,and manual measurement requires high standards.Introduces a new method for automatically measuring indentation diameter.By scanning the plane around the indentation with a laser sensor to obtain sampling points.The difference between the height of the indentation boundary points and the height of the indentation bottom is obtained after processing the sampling points.Finally,the diameter of the indentation is calculated based on the height difference.The experimental results of this method have been verified to be relatively accurate through comparison,which reduces human subjective errors and improves measurement efficiency.关键词
