摘要
Abstract
At present,piezoelectric force sensors are often used in high precision real-time monitoring system of terminal crimping state at home and abroad.Although its dynamic performance is exceptional,the accuracy and stability are only average and the price is high,which has a significant impact on how widely the system is used.Traditional strain gauge force sensors have the advantages of mature technology,high precision,and low cost,but they are ineffective due to the mechanical structure of the terminal crimping.The crimping die's base plate is direct used as an elastic body,and a force sensor based on strain gauge is designed for real-time monitoring of termi-nal stress condition.To ensure high sensitivity and signal-to-noise ratio,the designed sensor direct takes the stress concentrated part of the base plate as an elastic body by machining the base plate of the terminal machine,so as to maximize the stress sensing device close to the stress part of the crimp terminal,and the strain gauge is pasted on the most sensitive position of the base plate,to high sensitively sense the terminal's stress condition.The experimental data analysis shows that the pressure monitoring system using the sensor can re-place the current piezoelectric sensor,and effectively distinguish the wire harness with bad crimping state lowering the cost of the real-time monitoring system for terminal crimping state and effectively improving product yield.关键词
