Five Key Laser Marking Technologies

This article provides an in-depth analysis of the five core technologies in the laser marking field, including technology principles, patent layouts, and practical applications.This article will explore how to improve the efficiency, precision, and material adaptability of marking technology, and provide useful reference for those in the industry.

Why is it necessary to pay attention to core laser marking technology?

Laser marking technology has been developing very quickly in recent years, and is used for a variety of applications, from marking the logos on mobile phone casings to making precision markings on medical equipment.But do you know that what really determines the effectiveness and efficiency of the tags is the core technology behind them?These patents not only hold the secret to technical breakthroughs, they may also directly affect your choice of equipment and production costs.

Patent analysis of five core technologies.

Precision beam control.

If you want to mark a hair-thin strand of material with a clear, sharp mark, the key is to control the beam of light.These patents mainly solve problems of laser focus and path optimization, such as dynamically regulating the size of the laser spot.Many of the "micron-level marking" features offered by manufacturers are based on this technology.

The multi-material energy adjustment.

Different materials, such as metals, plastics, and ceramics, absorb lasers to very different extents.The related patents describe how the laser can use real-time monitoring and feedback to automatically adjust the laser power and pulse frequency.For example, a German brand called "SmartPower" can automatically switch between modes depending on the hardness of the material, avoiding the problems of burning or not marking deeply enough.

High-speed scanning mirror system.

The speed of the labelers has a direct relationship to production.High-speed scanning The patent for high-speed scanning was obtained by optimizing the algorithm for the motor drive, which increased the scanning speed to more than three times that of the conventional equipment.Last year, a leading Taiwanese company launched its "flash marking" series, which uses this technology to take on a major order from the auto parts industry.

The company has also developed an eco-friendly cooling solution.

If you're worried about your system overheating from prolonged use, the new cooling system uses a combination of heat pipe conduction and forced air cooling.Compared to traditional water cooling systems, this not only saves maintenance headaches, but also cuts energy consumption by 30 %.Some of these plans can even recycle the leftover heat to warm the factory, killing two birds with one stone.

Intelligent visual positioning technology.

The patented system with machine vision can automatically identify the contours of irregular workpieces and correct the position.The case of a Japanese company shows that this technology reduces the time needed to prepare for marking a cell phone case from five minutes to 20 seconds, and also increases the yield of good products by 12 %.

How can we choose the appropriate technology?

The key is to match the technology to actual needs.If a company is producing small batches of many different products, they should first consider smart vision systems and material matching technology. If a company is always trying to meet production quotas, they should consider high-speed scanners and cooling systems.It is suggested that you should take samples with you to test with the supplier, and see for yourself the results of the marking and the stability.

Forecast of future technology trends.

From the patents recently published, it seems that the integration of AI algorithms into control systems is a major trend.For example, we can use machine learning to predict material reactions and automatically optimize parameter combinations.Other green manufacturing technologies are also likely to receive more attention, such as waterless cooling and low-power modules. These may become the focus of the next wave of upgrading.
