Electromagnetic jetting dispenser( EJD) is a non-contact dispensing device used in electronic packaging. The dynamic model for EJD’s needle is established
and the working process is simulated by MATLAB/SIMULINK
the simulation and experiment have good consistency. The rise delay time
rise process time
hold limit time
reset delay time
reset process time of the needle movement are used as the dynamic characteristic indicators
the law of the influence of driving parameters such as starting voltage
holding voltage
spring stiffness
spring preload on the dynamic characteristics is obtained experimentally.
