Laser marking machines are becoming more and more widely used in today's modern industrial fields. In fact, the electronic products we can see are all marked by laser marking machines. Traces of the laser marking machine can be seen including food, machinery and so on. Our common purchasing laser grade optical prism marking machines are mainly divided into three types: semiconductor laser marking machine and carbon dioxide laser marking machine, optical laser marking machine.

Today, Xiaobian wants to introduce to you the important components in the laser marking machine: galvanometer. Usually, the galvanometer of the wholesale high efficiency laser grade optical filter machine is composed of two parts: the first is the controller; the second is the vibrating lens (motor), what effect does the galvanometer have on the performance of the laser marking machine? What is the role?

Laser marking machine galvanometer motor motor classification; usually, the motor is mainly divided into four categories: AC motor, DC motor, AC motor, special purpose motor. AC motors include synchronous motors, asynchronous motors. Special-purpose motors include electric dynamometers, synchronous camera, camera, micro-motors, and other special-purpose motors. The laser marking machine vibration lens belongs to the oscillating motor in other special purpose motors.

Laser marking machine vibration lens consists of three parts: stator, rotor and detection sensor. The vibrating lens is a moving coil type (the rotor is a coil), the other is a moving magnetic type (the rotor is a magnetic core), all the vibrating lenses are made of permanent magnets as magnetic cores; the detecting sensor analog galvanometer is a capacitive sensor. The digital galvanometer is a grating scale detection sensor. The capacitive sensor is a small change in the capacitance of the detecting sensor when the motor is oscillating, and the amount of change in the capacitance is converted into an electrical signal, which is fed back to the controller for closed-loop control. The grating scale sensor measures the actual deflection angle through the grating ruler, thereby converting into an electrical signal, and feeding back to the controller for closed-loop control. Because the rotor is a coil, the coil is relatively large in volume and large in inertia, which is not conducive to rapid response, so it is basically not used now. Therefore, the magnetic-magnetic type core-core magnetic core is tightly mounted on the rotating shaft, and the volume is small, the inertia is small, and the quick response performance is good, which is more conducive to high-speed marking of the special high precision optical lens manufacturer/supplier marking machine.

The laser marking machine relies on the X and Y vibration deflection to reflect light onto the work surface for precise engraving. The control of the galvanometer is controlled by the open loop of the computer. Therefore, the requirement must be linear, that is, the input signal has a linear relationship with the deflection angle. Since the galvanometer is a fast precision machine, it is required that the acceleration from the working state to the other working state is as high as possible, so that the marking time of the laser marking machine is infinitely small.
