Laser Pointer

Plastic, which is a synthetic polymer material with plasticity. Plastic products are collectively referred to as living or public goods that are processed from plastics. Plastic products are within reach of our daily lives, such as plastic bowls, plastic buckets, water cups, faucets, mobile phone cases, lamps, etc., and are one of the most widely used materials. In general, green laser pointer is mainly used in agricultural plastics, packaging plastics, architectural plastics, decorative plastics, medical plastics and other industries. With the advancement of technology, the change of plastic synthetic materials is increasingly used in the field of consumer electronics. Many, such as mobile phones, computers and other products.

Glass is a brittle material. It is easily broken by external forces during processing. Mechanical stress and thermal influence can cause glass to break. Therefore, the precision of glass material processing is high, and even in some high-end applications, even It will be stress tested and used. So in some high-end glass applications, what is the way glass processing is processed?

From this we can see the importance of plastics in our daily lives. The wide application of plastics affects our daily lives. Therefore, in order to improve the brand influence of their own products, manufacturers also promote brand promotion and user experience. In order to facilitate the use of downstream products, it is necessary to mark clear and beautiful production date, logo, patent number, company name, parameters, instruction name, number and other information on the plastic products.

To mark a clear and beautiful string image, you need to use a special device for marking, such as a plastic laser marking machine or a coding device.

The ultraviolet 488nm laser pointer cutting machine adopts the ultraviolet laser with cold light source, the spot is small, the heat affected area is small, the non-contact processing has no mechanical stress, and the processing speed is fast. The disadvantage is that the thicker glass is drilled, and the ultraviolet light is tapered, that is, the upper surface of the drill hole is small, the small surface is small, and the processing thickness is low.

Taking biological reagent glass scribing and drilling as an example, usually the surface of such a glass will be subjected to texturing treatment, and the treated surface is better processed by surface treatment by ultraviolet laser focus, and the surface without the texturing treatment will be better. Rough.

The working principle and materials of the coding equipment limit its development. The inkjet itself has the problems of high pollution, high consumables, high failure and high maintenance, which limits his application, such as in the food field, it needs to be used with caution. In addition, in some long-contact products, it is easy to erase, which is not conducive to use, such as light switches, chargers, etc.

From the above ultraviolet laser cutting machine compared to the glass scribing, drilling and machining methods, the size of the chipping can be seen by magnifying the machining drawing and surface comparison, and the UV laser processing is obviously superior to the machining. From the perspective of the smoothness of the surface, the military laser pointer filling method is slightly worse than the machining.

In comparison, the biggest advantage of UV laser cutting machine processing glass compared with machining is processing speed. Machining needs to be cooled and rinsed by water. In bioglass applications, drilling and scribing need to be processed separately. The laser does not need such a device, one-time molding, fast speed, small collapse, no stress, and low thermal influence, which is the biggest advantage of ultraviolet laser cutting machine for cutting glass.

Correspondingly, the plastic laser marking machine has become an effective processing method, which is characterized by non-contact processing, no pollution, high operation precision, fast marking speed, easy operation and permanent marking effect. Plastic waterproof laser pointer marking machines have become the preferred marking machine in the plastics industry.

In the huge application market demand, the development of plastic products has been promoted, and when laser marking opportunities are on plastic products, the two quickly produce chemical reactions, which has ushered in new development opportunities for plastic products, while laser products in the plastic products industry The use of the standard machine also promoted the development of the laser marking machine industry. Based on the industrial characteristics of plastic products, Yuanlu Optoelectronics has developed CO2 laser marking machines, fiber laser marking machines and UV laser marking machines for different plastic materials.

According to the requirements of different plastic materials, the types of laser marking machines are different. For example, ABS marking usually selects UV laser marking machine, PE, PT, PP and other materials can choose UV or CO2 marking. Yuanlu Optoelectronics has developed sophisticated usb laser pointer marking equipment for different industry characteristics and material properties. The marking effect is ideal, the operation is simple, the performance is reliable, and the processing flow of the assembly line can be satisfied.

Environmental requirements and the trend of lightweight make plastic more and more alternative industrial products in the metal part, and plastic green laser light welding relative to other welding technology, has more advantages:

Non-contact welding, no physical contact with the workpiece to be welded, no chemical reaction of the thermoplastic, operation in an industrial environment, suitable for medical and food industries requiring hygiene and safety. Medical industry is mainly used for injection systems, medical electronic equipment, a variety of artificial implants and stoma products.

Laser beam shape and size can be controlled, so as to control the size of heat-affected zone and joint area, high flexibility and good flexibility. Not limited to the size and shape of the parts to be welded, to achieve two-dimensional or even three-dimensional welding, to provide a basis for diversified custom parts production.

Welding speed, high weld strength, no flash, no residue, to ensure a good appearance of the welding area. Relevant data show that for ordinary passenger cars, the weight of non-metallic materials accounts for about 1/3, some of the larger proportion of models, plastic is one of the four non-metallic automotive materials. High-end car bumpers using plastic laser welding can achieve the best of both worlds. Other such as automotive filters, gas-liquid separator, car dashboard shell, electronic door openers, gearbox and other burning laser welding can play a good effect.

Precise and firm, airtight, watertight, can greatly reduce thermal stress and vibration stress, the most suitable for precision electronic components and vulnerable components.

Optogenetics is a booming multidisciplinary bioengineering technology. It has the characteristic of high spatial-temporal resolution and cell-type specific. It overcomes the disadvantages of traditional methods of the activity control for the cell and organism, and also provides a revolutionary method for the research of neuroscience. The research fields include fundamental research of neural circuit, study and memory research, habituation research, dyskinesia, sleep disorders, parkinsonism, depressive disorder, anxiety disorder etc., and many classic laboratory animal germ line (drosophila melanogaster, nemathelminth, mice, Marmoset, and machin etc.).

Neuroscience is the scientific study of the nervous system. It is currently an interdisciplinary laser pointer science that collaborates with other fields such as chemistry, computer science, engineering, linguistics, mathematics, medicine, genetics, and allied disciplines including philosophy, physics, and psychology. It also exerts influence on other fields, such as neuroinduction and neurology. The scope of neuroscience has broadened to include different approaches used to study the molecular, cellular, developmental, structural, functional, evolutionary, computational, and medical aspects of the nervous system.

Laser welding is a relatively common field of laser technology applications, the development of China"s manufacturing industry makes China"s demand for welding will continue to grow and may become the next point of attack. For laser welding, welding quality is critical. Welding quality in addition to the laser welding process, the choice of laser, welding materials, etc., but also with the surface of the welding material has a direct relationship between the state. Laser cleaning technology, in simple terms, is the use of a certain wavelength of the laser generated by the high frequency of vibration, the surface of the object attached to the shatter; the use of green laser pointer generated by the instantaneous high temperature so that the object off the substrate surface, so as to achieve the purpose of cleaning. The Laser cleaning objects include any material surface contamination layer, paint layer, rust layer, adhesion layer and so on. Its application mainly includes: mold cleaning, metal surface paint layer and the removal of welding points, oxide, oil and oil scavenging, the restoration and preservation of historical relics and so on.

Simple structure, strong adaptability, easy to manufacture, easy to ensure high accuracy, can be made into small size sensor to achieve special measurement, can work in high and low temperature, strong radiation and strong magnetic fields and other harsh environments, can withstand high pressure, Impact, overload and so on. Dynamic response is good, because the electrostatic attraction between the plate is very small, the role of the required energy is very small, and its movable part can be very small and very thin, so its inherent frequency is very high dynamic response time is short, Frequency work, especially for dynamic measurement. Heat is small, its own temperature coefficient is small, because the capacitive capacitance of the capacitor value is independent of the electrode material, you can choose a low temperature coefficient of material, in the case of external temperature stability, can guarantee good stability. This shows that these advantages are very suitable for high power laser processing, for laser cutting head, it can be said that the use of capacitive displacement sensor is most appropriate.

Environmental requirements and lightweight trends make plastic more and more alternative to industrial parts of the metal parts, and plastic laser welding relative to other welding technology, with more advantages: non-contact welding, and the workpiece to be welded without physical contact, thermoplastic Does not occur chemical reaction, can be operated in industrial environment, suitable for health and safety of medical and food industry. The medical industry is mainly used for injection systems, medical electronic equipment, all kinds of artificial transplant and stoma products. The shape and size of the laser beam can be controlled to control the size of the heat affected zone and the joint area, high degree of freedom and flexibility. Does not limit the size and shape of the parts to be welded, can achieve two-dimensional or even three-dimensional welding, for the diversification of customized parts to provide a basis for production.

With the emergence of laser welding machine, the advantages of laser pen welding for thinner materials have become increasingly prominent, both in the welding heat control and spot control can be done with the demand. Fiber laser welding machine is the use of energy fiber, the laser generated by solid-state laser, through the laser coupling technology to the fiber, and then the fiber in the laser through the output mirror to the workpiece surface, to achieve the purpose of welding. The use of optical fiber transmission laser, you can use the flexibility of the fiber, so that the laser can be arbitrary angle of the workpiece processing, to achieve a multi-dimensional flexible processing. Fiber on the laser energy and homogenization, the laser spot energy can be modeled output, and the laser for homogenization, so that the laser beam quality is better to improve the quality of welding. Use energy feedback power output energy laser can do the same spot.

The use of laser cleaning can avoid the above problems, has the following advantages: cleaning light source can adapt to the arc surface morphology, to minimize the destruction of the substrate, corrosion removal rate of more than 99%, substrate damage <0.01 mm; Cleaning can achieve the selective cleaning of pollutants, improve cleanliness, protect the substrate; no supplies green cleaning technology to eliminate dust pollution, significantly reduce the cleaning costs; cleaning light source can be used flexible fiber transmission, and robot integration work; greatly improve the cleaning quality, Improve the welding yield, rail welding strength and reliability, to eliminate security risks.

Laser welding market is broad, with the corresponding pre-welding pre-treatment needs will increase, red laser pointer cleaning technology to achieve no damage to the substrate and no secondary pollution pre-treatment, is to ensure the quality of welding is a good helper.

It combines liquid cooling with solid-state purple laser pointer technology (https://www.htpow.com/100mw-blueviolet-laser-pointer-fixed-focus-p-1058.html) . Although laser weapons may see some offensive applications. In practice, the spectrum of most types of lasers can. The resulting frequency variations of the laser therefore amount to less.

Higher quality purple laser pointer can maintain their perfect wave for longer. The new laser really set the standard for laser quality. These new incredibly precise lasers have applications in atomic clocks. A similar plan is in place to connect the lasers.

In fact, development of laser-resistant materials and countermeasures has proceeded apace despite lasers having yet to enter widespread operational use. Indeed, lasers might be practical for disabling small ground vehicles.

However, it does not restrict the use of green laser pointer against manned vehicles (https://www.htpow.com/300mw-green-high-power-laser-pointer-waterproof-adjustable-holster-p-1038.html) . Real laser weapons project a coherent ray of directed photons (light) that strike their target virtually instantaneously. Most importantly, lasers could be very cheap.

As much as green laser pointer helicopters might seem like they belong in a video game. Why use a laser instead of a bullet, shell or missile? However, lasers do come with disadvantages that have held back their adoption for decades. Laser weapons require powerful electrical generators or dangerously volatile chemical fuels.
