Five Key Steps to Labeler Parameter Adjustment

The video provides a detailed explanation of the method of adjusting the parameters of the laser marking machine's frequency, covering five core steps including frequency range testing, material matching testing, and software parameter synchronization. This helps operators quickly identify problems with the equipment to improve marking accuracy and efficiency.The system can be used for common materials such as metals and plastics.

Preparing to adjust the frequency of a laser marking machine.

Before adjusting the frequency parameters, make sure that the equipment is in a cooled-off power-off state and that you are wearing protective eyewear.Prepare samples of different materials (such as a metal plate and a plastic board) and have the operating manual ready.Don't rush to adjust the settings. First check to see if the current frequency parameters are the same as those recorded last time.

Check the frequency support range of the equipment.

Check the specifications.

Each machine has a different frequency range; some can go up to 200kHz, some only 50kHz.It's best to check the instruction manual and compare the equipment's specifications, rather than relying on past experience, especially with used equipment or modified models.

Testing the frequency response.

They would first use the lowest possible frequency to see if the marking process would break down, then gradually increase the frequency to the maximum to test if the laser head would overheat or the marking become blurry.This step allows one to quickly determine the condition of the equipment.

Testing material and frequency.

The following are the key points to remember when working with metals.

Stainless steel and aluminum alloys require higher frequencies (80-120kHz), while highly reflective materials like copper need lower frequencies (30-50kHz) and a delay factor.Don't be afraid to experiment with scraps of material.

Points to note about non-metallic materials.

Plastics and acrylics tend to burn easily, so we started with 40 kHz and reduced the power.When dealing with PVC and other chlorine-containing materials, you have to be particularly careful. If the frequency is too high, it will produce toxic gases. At such times, you have to sacrifice speed in order to guarantee safety.

They are then synchronized with the software.

Software version confirmation.

We have seen many cases in which parameters have not taken effect because the software has not been updated.The key point is to check if the marking software is compatible with the controller firmware, especially for equipment that has just had a system upgrade.

Adjusting the relationship between parameters.

Frequency is not a parameter that acts independently. It has to be coordinated with the spacing between scans (0.01-0.1 mm) and the scanning speed (100-2,000 mm / s).The general rule is "high frequency, fast scanning; low frequency, dense filling.

Environmental factors.

Power supply stability detection.

Using a multimeter, check that the working voltage is stable at 220V ± 5 %.Fluctuations in voltage will cause the frequency to shift, especially when several machines are operating in a factory at the same time. It is suggested that voltage stabilizers be added.

Heat dissipation system.

Feel the temperature of the heat sinks, listen for the sound of the fans.If the cooling system is not working properly, the computer will automatically reduce the clock speed. In this case, adjusting the parameters is useless. The first thing you need to do is to solve the cooling problem.

Calibration records and effectiveness verification.

Set up a parameter table.

Prepare a notebook, and after each test write down the "material type + frequency parameter + effect description.Three months from now, you'll thank yourself for having this habit, especially when you have to deal with repeated orders and can directly call up historical data.

The sample was verified before the batch was produced.

Before mass production, a sample must be made using the same batch of materials. The most important thing is to check the depth of the carvings at the corners.Don't be put off by the bother. This step can prevent the whole batch from being scrapped.
