Basic understanding of laser marking machine

Laser marking machine is a high-precision, high-efficiency industrial marking equipment, which can mark and engrave various materials, and is widely used in electronics, machinery, medical, clothing and other industries. The following is a simple laser marking machine tutorial to help you quickly get started with the use of laser marking machines

Step 1: Understand the structure of the laser marking machine

Laser marking machines are usually composed of laser generators, lenses, scanning heads, computer control systems and other parts. The laser generator is responsible for generating a high-energy laser beam, which is reflected and focused by the lens, and finally forms the desired mark on the surface of the workpiece. The scanning head is responsible for controlling the movement trajectory of the laser beam, converting digitized images and texts and other information into laser printing patterns.

Step 2: Safe Operation

The laser marking machine is a high-energy device that requires attention to safe operation. Before use, read the instruction manual carefully to understand the relevant safety precautions. In particular, pay attention to the following points:

1. Wear protective glasses to prevent the laser from directly irradiating the eyes and causing damage.
2. Do not touch the laser head to avoid burns.
3. During use, keep the environment around the machine neat and clean, and prevent dust and other substances from entering the machine.

Step 3: Software Settings

The corresponding marking software needs to be installed before using the laser marking machine. Common marking software include AutoCAD , CorelDRAW , Photoshop , etc. Before use, you need to input the required image or text information into the marking software, and make settings, including printing parameters, text size, font, printing speed, power, etc.

Step 4: Start marking

1. First place the item to be marked on the workbench of the laser marking machine and fix it so that it does not shake or move.
2. Import the set marking file into the marking software, and connect the workbench with the software.
3. According to the instructions in the marking software, import the required text, images and other information into the laser marking machine.
4. Adjust the focal length of the laser marking machine so that the laser beam is focused on the object to be marked.

5. Adjust the marking speed, power and other parameters of the laser marking machine as needed, and start the marking machine.
6. Wait for the marking machine to complete the task, and check the marking results. If you need to re-mark or modify, you can adjust the parameters again and print again.
7. Clean the workbench and laser head to keep the machine clean and tidy.

Note: When using a laser marking machine, it is necessary to avoid direct exposure of the laser beam to the skin and eyes to avoid burns and damage caused by the laser. In addition, pay attention to the safety of the environment when using the laser marking machine, try to place the machine in a fixed place, and avoid shaking and moving the machine during work.

Laser marking machine is a high-precision, high-efficiency industrial marking equipment, widely used in electronics, machinery, medical, clothing and other industries. When using a laser marking machine, it is necessary to understand the machine’s structure and safe operation specifications, follow the instructions for use, and pay attention to safe operation. In terms of software settings, appropriate adjustments need to be made in order to obtain the desired marking effect. Finally after use, the machine should be cleaned and maintained in order to keep the machine in good condition.

Basic knowledge of laser marking machine galvanometer

The laser marking machine galvanometer is a very critical part of the laser marking machine, which can control the trajectory of the laser beam and achieve high-precision marking on the workpiece. In the laser marking machine, the galvanometer is driven by one or more motors to achieve precise control of the laser beam by reflecting the laser beam. This article will introduce the basic principles, types, common faults and maintenance methods of the galvanometer of the laser marking machine.

1. The basic principle of laser marking machine galvanometer

The basic principle of the laser marking machine galvanometer is to use the galvanometer to reflect the laser beam, and change the angle of the galvanometer through the rotation of the motor, thereby changing the reflection direction of the laser beam. The galvanometer in a laser marking machine usually consists of two components: a scanning mirror and a motor. The motor rotates and drives the scanning mirror to change the angle of the scanning mirror, thereby controlling the reflection direction of the laser beam. Due to the fast response and high accuracy of the galvanometer, it is widely used in laser marking machines.

Second, the type of laser marking machine galvanometer

Laser marking machine galvanometers are mainly divided into two types: scanning galvanometers and holographic galvanometers. The scanning galvanometer controls the reflection direction of the laser beam by rotating, which is suitable for high-speed movement and large-area marking of laser marking machines. The holographic galvanometer uses the interference principle of light to divide the laser beam into multiple small beams, and controls the phase difference of these small beams by changing the angle of the holographic galvanometer, thereby changing the reflection direction of the laser beam. Accurate, high-resolution marking requirements.

3. Common faults and maintenance methods of laser marking machine vibrating mirror

The position of the galvanometer is not accurate

The inaccurate position of the galvanometer is one of the common faults of laser marking machines. When the angle of the galvanometer is inaccurate, the position and direction of the laser beam will be deviated, which will affect the marking effect. This failure is usually caused by a loose or damaged galvanometer, requiring adjustment or replacement of the galvanometer.

Vibration mirror

Vibration of the galvanometer is another common failure. When the galvanometer is not working smoothly or is disturbed by external force, the galvanometer will vibrate or vibrate, resulting in unstable position and direction of the laser beam. This kind of failure is usually caused by reasons such as the galvanometer is not fixed tightly or the motor drive is unstable, and the motor needs to be adjusted or replaced.

Dirt on the mirror surface

Dirt on the surface of the galvanometer will also affect the effect of laser marking. When there is oil or dust on the surface of the vibrating mirror, it will cause uneven reflection of the laser beam, which will affect the marking effect. This failure can usually be resolved by cleaning the surface of the galvanometer.

Galvanometer motor failure

The failure of the galvanometer motor is also one of the common failures of laser marking machines. When there is a problem with the motor drive, it will cause the vibrating mirror to work abnormally, which will affect the laser marking effect. This failure usually requires motor replacement or circuit adjustments.

When repairing the galvanometer of the laser marking machine, it is necessary to power off the machine first and wait for the machine to cool down completely before proceeding. Inspection and testing are then required to determine the cause of the failure. For different faults, different maintenance methods are required, such as fastening loose vibrating mirrors, replacing damaged vibrating mirrors or motors, etc.

The laser marking machine galvanometer is a very important part of the laser marking machine. It controls the trajectory of the laser beam to achieve high-precision marking on the workpiece. When using a laser marking machine, if the galvanometer fails or has problems, it will directly affect the effect of laser marking. Therefore, it is necessary to regularly check and maintain the galvanometer of the laser marking machine to ensure its normal operation. When performing maintenance, you need to pay attention to safety to avoid injury to yourself and the equipment.
