Galvanometer laser marking machine era
Late 90s, galvo scanning system began to come application in China s large-scale laser marking machine field
Late 90s, galvo scanning system began to come application in China's large-scale laser marking machine field.
The galvanometer, may called ammeter meter, its design ideas entirely followed the ammeter design method, the lens replaces the hands, and the signal probe controlled by a computer -5V-5V DC signal substitution, to perform a predetermined action . With the same rotating mirror scanning system, the typical control system uses a pair of reflection mirror, the difference is that this lens of the stepper motor drive is replaced by a servo motor, in this control system, the use of the position sensor and a negative feedback loop design ideas to further ensure the accuracy of the system, the scanning speed of the entire system and repeat positioning accuracy to a new level.
