Nanosecond UV laser marking water cup｜Create your own handicrafts
Laser refers to a collimated, monochromatic, coherent directional beam generated by a narrow amplitude frequency of optical radiation through stimulated feedback resonance and radiation amplification. The laser originated in the early 1960s, and together with atomic energy, semiconductors, and computers, it is called the four major inventions of the 20th century.
As a new energy source, laser has been widely used in various fields due to its characteristics of good directionality, high brightness, and good monochromaticity. It mainly includes industrial, information, medical, commercial, scientific research, military and other application fields.
Ultraviolet laser water cup process
Today, I will talk to you about the knowledge of water cups. Water cups are not difficult to understand. Generally, containers used to draw water and keep warm are the most common and practical commodities in daily life. With the rapid development of science and technology, people's life has generally improved, and there are higher requirements for various substances, so the continuous improvement of water cup technology has become an indispensable trend.
There are many kinds of water cups on the market, which are dazzling, and everyone can choose the right cup according to their own preferences. Without considering the cost, the individually designed and artistic water cups often attract much attention. Nowadays, people prefer cups with exquisite craftsmanship and pure colors. The reason is very simple, because it gives more artistic space. Individuals can modify the cups according to their favorite patterns and words. A handicraft belonging to one's own masterpiece, when using Often full of intimacy and happiness.
UV laser marking principle
Ultraviolet laser wavelength is 355nm, narrow pulse width, fast speed, high precision, high peak value, easy absorption of materials, etc. It is also called "cold" processing method. It has ultraviolet photons with high load energy and can be cut and punched. , etching and other processes. A high-energy-density laser is used to locally irradiate the workpiece to vaporize the surface material or undergo a chemical reaction that changes color, thereby leaving a permanent mark. Today I would like to share with you how about the 5w UV laser of Ge radium laser? Whether it can meet the modern technology standards.
This is a stainless steel pure black water cup I bought on Tmall, mainly for drinking boiled water or making tea at work. It is made of 304 stainless steel, the body of the cup is made of stainless steel, and the paint process is not easy to fade. Such cups are also relatively common in the market. The surface seems smooth and flat, easy to clean, and it has a friction feeling in the hand, and it is not easy to slip off, which is why I choose it.
UV laser marking
Because the laser is used with the electronic computer, the computer is equipped with a lot of materials, which can be selected according to each person's needs. Because I belong to a horse, I chose a "horse" pattern and matched it with a sentence I liked, which is a classic dialogue between Zhuge Liang and Lu Su after borrowing an arrow in a grass boat. Geography; I don’t know about Qimen, I don’t know Yin and Yang; I don’t watch the formations, I don’t control the army; Next, is it good to experience UV laser marking? Let's find out together.
Rs232 remote computer control
When marking the water cup, first place it on the workbench, fix the cup with an iron block, measure the marking range with a ruler, and then adjust the parameters (size, power) through remote electronic computer control. For a professional laser marker, if you want to make a successful marking, you must first determine the material of the water cup, and then mark a small mark, such as marking today's date, and scan the surface of the cup with an ultraviolet laser to form a marking area. , you can first cover the surface with a layer of card, and then execute the marking instruction, which is equivalent to the sample marking.
Mark after measurement
After the sample is marked, check whether the font is parallel, how deep, whether the handwriting is clear, whether the marking effect is ideal, and then confirm the parameters, and then you can officially mark the water cup.
Determine marking parameters
The galvanometer will automatically scan the covered area, confirm that there is no deviation by observation, and then click the "confirm marking" command directly on the computer, we can clearly see a very bright light on the surface of the water glass, if you do not wear laser glasses, watch for a long time , it will cause certain damage to the eyes, so the masters who use lasers can only take up jobs after professional training, and everyone should pay special attention to this.
Laser marking is a chemical reaction that vaporizes the surface material or undergoes eye changes by locally irradiating the workpiece with a high-energy-density laser. During the marking process, we will hear a creaking sound from the cup, and a trace of white smoke rises rapidly on the surface, which is directly filtered by the smoker to keep the marking environment fresh. The pictures and texts are completely presented in more than ten seconds, and the speed is very fast.
From the real pictures, we can intuitively find that the pattern is beautiful, the font is neat and clear, and the "horse" pattern is to directly remove the paint on the surface, with a sense of friction, the periphery is smooth and flat, no Scratches, won't hurt hands. There is no friction when touching the marked area of the font, which is the same as the unmarked area. Compared with the computer design scheme, the two are basically the same.
This is a water bottle designed by myself. Whenever I use it to drink water, I can't help but take a few more glances. At the same time, it is also a beautiful scenery on my desktop, fashionable and unique, especially the classic sentence, Makes me feel better. Now, it has become an indispensable part of my life, whether it is for office or business trip.
Epilogue
Ultraviolet laser is one of the major application lasers of continuous fiber laser. With the transformation of traditional industries to high-tech, especially the rapid development of 3C industry, electronic products have been upgraded in the direction of high integration and high precision. . In product development, the pursuit of lighter, thinner and more portable designers has brought about continuous progress in new materials and new processes. Ultraviolet lasers are applied with their natural "cold processing" properties, which can meet most processing precision requirements. As the laser technology becomes more and more mature, the nanosecond-level laser of the current Geradi Laser will develop to the picosecond-level laser, and the application will become more and more widely. While promoting the production of enterprises, it also accelerates the development of the laser industry.
