Fiber laser marking machine on-line laser marking method in the object surface to play a vertical line with the E axis: When the object is stationary, as long as the control y direction of the galvanometer drive a signal to deflection of a certain angle, you can Play a line segment, when the object level to the right, if also in accordance with the fiber laser marking machine static marking, will produce distortion. If the object moving speed is high, and the marking speed is not very high, the deformation is very obvious, then will play a line to the left offset, in order to amend the deformation, the fiber laser marking machine online laser The direction of the galvano mirror rotating a certain angle to compensate for the deformation caused by the movement of objects. If the object is stationary, only the speed signal of the conveyor is input to the system, and its inclination direction is opposite to the straight line in the object. Finally, put the object on the movement of the conveyor belt on it.
Through real-time correction, fiber laser marking machine on-line laser marking and the same straight line, not only can detect the speed of the conveyor belt, can also detect its direction. When the belt moves in the opposite direction, the phase difference of the coded signal is opposite to that of the original. The counting pulse number depends on the speed. The relationship of the coded signal depends on the direction of motion.
In the correction of flight deformation, when the object along the uniform movement in one direction, may not increase the speed device, but simply using the circuit or software method to produce a uniform analog signal, fiber laser marking machine online laser marking with the signal on the vibration Mirror to compensate. But when the object velocity is not constant, the fiber laser marking machine online laser marking in order to compensate for object movement caused by font deformation, the use of the encoder to detect the target instantaneous movement speed, and through the connection system input to the computer, real-time compensation .
