Laser Marking Machine

Application in Consumer Electronics Industry:Computer is an important electronic device in every family, it is an essential electronic device in people&qu39;s life and work, used for collecting information, documents, sending and receiving emails, editing documents and so on. As a result, the markings on computer mice and keyboards do not show letters or numbers for a long time. Prolonged exposure can lead to fading. Now logos will have laser marking capabilities. The laser marking machine uses laser output signals to achieve the marking function through a high-speed scanning galvanometer system.

Laser marking machine light conversion efficiency, air-cooled, small size, good light efficiency, high reliability. Laser marking technology is different from traditional screen printing and thermal transfer printing: laser marking produces text or patterns that can identify gender. Engraving a unique customised pattern, the pattern can be any graphic element, such as flowers, landscapes, humanistic landscapes and so on.

Laser marking is a personalised laser engraving method, referred to as TIME. advanced laser marking technology is used to engrave personalised patterns, and the effect of colour change of the pattern is displayed using the mouse&qu39;s built-in far light led. The core of the laser marking machine is to combine the three elements of culture, technology and personal consumption creatively, with high-tech equipment, a little bit of the mouse to show the deep Chinese culture and the common culture of the European and American world. and keyboard.

Mouse and keyboard is not only a product, but also a cultural product that can express consumers&qu39; personal feelings. Unique interests and tastes are better able to meet the growing needs of individual consumer groups. Therefore, the mouse, keyboard and other products should be marked with good high-power laser marking to enhance the consumer experience.

UV laser marking refers to a laser marking process. Its principle is to use the laser beam to focus on the surface of various marking materials. Thin, can achieve very fine marking, heat range is very small, the thermal effect is relatively small, and there is no material burning problem, its advantages, can be applied to a wider range of materials.

Advantages of UV laser marking

Compared with infrared lasers, UV lasers use third-order intracavity frequency doubling technology in the 355nm range. During UV laser marking, the focal point of the laser beam is small and the thermal exposure during processing is small. It reduces the risk of deformation of the labelled material and is ideal for fine processing. It is mainly used for applications such as fine food labelling, pharmaceutical packaging labelling, circuit board labelling and glass material labelling.

Most laser applications in the market use infrared laser generators such as carbon dioxide, fibre optics, semiconductors and wafers, but green and ultraviolet light are also available. Of these, infrared laser therapy technology is by far the most mature. This type of laser therapy is widely used in industry, but the potential market for green and UV lasers is also very large. This has not yet been fully realised, especially with regard to the technological and market development potential of UV lasers.

UV laser marking is usually used for fine marking of special materials and is preferred by customers with high marking power requirements. The high-energy UV photon molecules of the UV laser process act directly on the surface of the object to be treated, rapidly removing the molecules from the metallic or non-metallic material. The heat generated in this mode of operation is very low, which is also different from conventional laser applications.

UV laser marking works better on product materials as they have clear patterns and fine textures. The use of UV laser treatment reduces the chances of the material being mechanically affected by 1 per cent, reducing the quality of the workpiece, the stability of the quality and the workability. It is best to emphasise the benefits of good care. I believe that UV lasers will mark the future of the laser market for other technological innovations and industrial applications.

h - moe-induced self-aligned LIPS with large-area nanostructures

The sequential generation of LIPS takes into account four types of laser scanning conditions and their combinations:parallel to polarisation when the scanning direction is parallel to polarisation, perpendicular to polarisation when the scanning direction is perpendicular to polarisation, and each time we ablate parallels we always scan the paths at the same volume and in the same direction (the default direction is left to right) and ablate the scanning paths both forward and backward by the parallels to be ablated .

During femtosecond laser Gaussian polarisation parallel scanning, local LIPSS perturbations occur, including offsets, directional bending and hinging, and sequential tilting as the scanning interval decreases.

When the distance d between neighbouring scan lines is large enough to exceed the effective distance that leads to the h-MOE phenomenon (> 4.5 µm under experimental conditions), there is no interaction between the LIPSs of the two scan lines. As d decreases, an adaptive half-cycle shift occurs locally in the vicinity of the LIPS peaks due to the redistribution of the SPP caused by the h-MOE phenomenon.

In large-area production of LIPSS, the degree of smoothing in long-range LIPSS depends strongly on the laser scanning path. In general, for most metallic and semiconducting materials, the LIPSS is polarised perpendicular to the laser in a single scan because the energy release follows the distribution of the SPP, which is usually perpendicular to the polarisation of the incident laser that excites the SPP. These very uniformly tilted grids are important experimental results.

The process of growing LPSS using polarisation-parallel sampling can be divided into four stages.

(1) Creation of a networked LIP: Starting from the first LIP, a stable and uniform LIP is developed with no apparent periodicity, which gradually adapts after the first pulse due to the gradual strengthening of the network connections. With the release of ablation energy, the depth of the LIPS is gradually increased to better meet the phase adaptation of the lattice coupling effect. Experimental data and simulated cross sections for SPP optimisation based on dot bonding are given.

(2) LIPSS Orientation:Self-alignment due to the h-MOE phenomenon leads to the existence of oriented links between two asynchronous LIPSSs on two neighbouring scan lines, despite the initial presence of local disturbances, including branches. When irradiated with a laser beam with a Gaussian intensity distribution, scanned sequentially from left to right, the actual pulses overlap, generating LIPSs in the direction of the incompatible waves, and hence directional LIPSs.This link provides a self-orienting extension of the LPSS.

(3) Lip self-alignment:The curved lip gradually straightens and tilts.The durability provided by the nonlinear optical properties of SPP contributes to this self-alignment property. In particular, the redistributed electric field can be viewed as a superposition of parasitic fields from all scattering centres, where the near-field scattering is strongly disturbed by local perturbations. However, outside the progression centres, the SPP tuning stability exhibits a smoother wavefront than the progression centre perturbations, which will help to match the energy supply generated by the LIPS. Also, the h-MOE phenomenon due to the SPP perturbation is resistant to small perturbations in LIPSS.

(4) LIPSS self-consistent growth:Since the phase-matched shape of the gate-switching effect is always populated, the existing ripples caused by SPP optimisation and branchless network connections can be exploited to facilitate the expansion of LIPSS.

It should be emphasised that the above four phases of uniform, self-aligned and angular lip growth are theoretically not limited to the treatment area, the incident laser (including various illumination conditions such as laser beam, wavelength and power) and the irradiated material. In addition, it can be seen that the inclination angle θ decreases with decreasing d, with different rates of decrease for different materials.

In parallel-polarised scans, where the distance d between scans is relatively small, the tilted LIPS is of a different scale than before because the LIPS is perpendicular to the laser polarisation, whereas the vertically-polarised counterpart makes the LIPS perpendicular to the laser polarisation. laser polarisation. To explain this phenomenon, a competing mechanism between TOE and MOE was proposed and further experiments were conducted by changing the angle between the polarisation and the scanning direction.TOE is a near-field optical enhancement of the nano-groove tips, leading to ablation of the nano-grooves that always extend perpendicular to the laser polarisation direction. However, a strong enough tip effective ablation can only be achieved when the groove width is small enough.
