SINO GALVO Head Set RC1001 Scanning Galvanometer With Red Indicator Light Fiber CO2 UV Laser Marking Machine Galvo Scann

What is the function of a galvanometer scanner?

The galvanometer scanner, abbreviated as galvanometer scanner, is a device used to quickly and accurately guide a laser beam onto a surface.

It consists of two main components: a galvos motor and a mirror.

The functions of a galvanometer scanner

1.Beam control:

The main function of a galvanometer scanner is to guide the laser beam to different directions at high speed and precision. This is achieved by adjusting the angle of the mirror installed on the galvanometer motor.

2. High speed scanning:

A galvanometer scanner can quickly change the direction of the laser beam, enabling rapid scanning of the entire surface. This is crucial for applications that require fast processing time, such as laser engraving and marking.

3.Precision control:

The galvanometer motor can precisely control the mirror angle, thereby guiding the laser beam with high precision. This accuracy is crucial for applications that require intricate and complex patterns.

Components and working principle

1.Galvanometer motor:

These are electromechanical devices that convert electrical signals into precise angular motion. The motor drives the small mirror installed on the shaft to rotate, thereby controlling the laser beam.

2.Mirrors:

The mirror reflects the laser beam and guides it to the desired position on the target surface. Typically, a galvanometer scanner uses two mirrors: one for the X-axis and one for the Y-axis.

3.Control system:

The control system sends an electrical signal to the galvanometer motor, indicating the angle at which the mirror should be placed. This system can interpret digital or analog inputs from computers or microcontrollers.

The advantages of galvanometer scanners

●Speed: Able to quickly move the laser beam and achieve high-speed operation.

●Precision: The laser beam has high positioning accuracy.

●Efficiency: Able to run continuously with high repeatability, enabling efficient operation in production environments.

When installing the galvanometer, it is important to pay attention to the following key points to ensure its normal operation and optimal performance:

1. Environmental requirements

①Clean environment: The installation area should be kept clean to prevent dust and impurities from entering the mirror system, especially the optical components and motor parts.

2. Mechanical installation

①Fixed firmly: The galvanometer should be firmly fixed to the frame of the marking machine to avoid any looseness or vibration. Use appropriate mounting brackets and fasteners.

②Position correction: Ensure that the optical center of the galvanometer is aligned with the optical path of the laser marking machine. By adjusting the position of the bracket and reflector, ensure that the laser beam accurately passes through the optical center of the galvanometer.

3. Light path adjustment

①Beam alignment: Use alignment tools or low-power laser alignment devices to ensure that the laser beam aligns with the optical axis of the galvanometer system. The beam should enter the galvanometer vertically and reflect along the correct path.

②Avoiding reflection interference: Ensure that the laser beam does not reflect onto other components inside the galvanometer system to prevent unnecessary interference and damage.

4. Electrical connections

①Cable connection: Connect the power line and control signal line of the galvanometer correctly. Check all connections for tightness and avoid bending or stretching of cables.

②Prevent static electricity: During installation and connection, take anti-static measures to avoid damage to the circuit and components of the galvanometer caused by static electricity.

5. Cooling system

①Air cooling: If the galvanometer is cooled by air, ensure good ventilation around it to avoid overheating.

②Water cooling: If using a water cooling system, ensure that the flow and temperature of the cooling water meet the requirements, and regularly check the working status of the cooling system to prevent blockage or leakage.

6. Software settings

①Parameter configuration: Set the parameters of the galvanometer correctly in the marking machine control software, including scanning range, speed, acceleration, etc.

②Calibration and debugging: Perform calibration and debugging in the software to ensure that the galvanometer can be calibrated and debugged as expected

③Scan the path accurately. Conduct testing and marking, check the quality of marking, adjust parameters to achieve optimal results.

7. Protective measures

①Dust cover: Install a dust cover or protective cover on the galvanometer system to prevent dust and other pollutants from entering.

②Laser protection: Take appropriate laser protection measures to prevent laser reflection or scattering from causing harm to operators and equipment.

8. Maintenance and upkeep

①Regular inspection: Regularly inspect the mechanical and electrical connections of the galvanometer to ensure that all components are operating properly.

②Cleaning optical components: Use appropriate cleaning tools and methods, regularly clean the reflector and lens of the galvanometer to avoid dust and dirt affecting laser transmission.

③Software upgrade: Keep control software updated to ensure compatibility and performance optimization.
