After using the laser marking machi for a period of time, there may be problems such as the laser marking machine not being able to mark normally or not emitting light. After careful investigation, we found that there was a problem with the galvo head.

At this time, we need to remove the galvo head and send it to the manufacturer or the designated repair station for repair and maintenance. You have to install the galvo head after repairing. This article is mainly about removing and installing the galvo head.

The steps to remove the galvo head are as follows:

1. Under the condition that the power is completely cut off, disassemble the power cord connector of the marking head. If some machine do not have this connector, you can ignore it.

2. Remove the field lens, protect it and cover it. During the operation, no items such as fingers can collide with the field lens, especially the lens.

3. Use hardware tools, usually pickpockets for inner corners, unscrew the marking head, and be careful to prevent the removed shell plate from connecting the galvanometer drive plate to prevent excessive pulling.

4. Unplug all wires, power supply wires, signal wires, and wires from the motor to the drive board.

5. Remove the drive board, pack it, and then remove the Y motor and X motor, and pay attention to packing. Pack the drive board and the X and Y motors together, the task of removing the galvanometer is completed and you can send it to a place where it can be repaired.

The steps to install the galvanometer are as follows:

1. Install Y motor and X motor first, and ensure that they cannot collide together at any angle.

2. Install two drive boards.

3. After connecting all the connections, test and adjust the angle and depth of the galvanometer motor to ensure that the final laser output center position is the center of the field lens.

4. Clean up the connection, and arrange the length of the wire, and then close all the covers of the marking head on the box.

5. After connecting the external cable, you can restart the machine. At this time, the galvo head installation of the laser printer is completed.

This tutorial is applicable to all series of laser marking machines.
