UV laser marking machine marking effect

UV laser marking machine is new laser marking machine which come out in nearly two years , its superior marking effect got the majority of manufacturers favored. Previously mainly rely on fiber laser marking machine and carbon dioxide laser marking machine to do mark. Although the fiber and carbon dioxide can be engraved in the general material marking, but because of its machine's own restrictions, can not achieve more refined, better effect. Such as use fiber laser to marking plastic, if fast, marking effect is not clear, if slow, plastic surface will be blistering, hand touch will obviously feel bump feeling.

The emergence of UV laser marking machine completely solve this problem, UV laser marking machine laser processing into a cold processing, because the high-energy molecules of ultraviolet photon, the need to directly deal with the metal or non-metallic materials above the molecular detachment, However, this detachment led to the separation of molecules with the material, this way of work does not produce heat, because it does not produce heat and the way the work of ultraviolet laser processing has become a cold processing. This is the difference between fiber laser and UV laser.

What is the application of the UV laser marking machine? UV laser marking machine is currently mainly used in some fine processing of high-end market, metaphor said some of the polymer packaging materials, flexible PCB board marking, silicon wafer micro-control, LCD LCD glass two-dimensional code to play Standard, all kinds of metal, plastic, building materials, communications equipment, etc. All above, can be used the UV laser marking machine.

Soldering machine support spot soldering, drag soldering and press soldering.

Automatic Soldering machine are mainly three soldering style, press soldering, spot soldering, drag soldering. Different soldering machines in different welding methods have its advantages. We can decide to choice the soldering machine according to the characteristics of the welding products.

Press soldering mainly solder joint need testing tension requirements, and the solder distribution is more uniform, no plug-in products, flat solder joints, you can use pressure welding. For the tensile requirements of the product is best to use automatic soldering machine solder, which is more match with clients requirement.

Drag soldering, the main requirements of the uniform distribution of solder joints and solder spacing greater than 0.1mm, this products need fixed plug. If the two solder joints are less than 0.1mm apart, do not need to fix the plug, if still use drag soldering will lead to product tin problems, this products using wave soldering or rewinding is better. The advantage of automatic soldering machine is to save time and improve efficiency.

Spot welding, products is mainly uneven distribution of solder joints or solder joints require high fullness. Of course, there is a case where the solder joints of the product are evenly distributed, but the inserts need to be fixed, which requires that one of the points be fixed and solder again. Because many products are uneven distribution of solder joints, usually choose spot welding, use automatic soldering machine to spot welding, with high efficiency.

The factors affect the quality of laser cutting

Laser Cutting Machine

Sinrad Laser summarize the factors that affect the quality of cutting: cutting speed, focus position, auxiliary gas, laser output power and workpiece characteristics! We will give you one by one to analyze:

                                  

1. The effect of cutting speed on cutting quality

For a given laser power density and material, the cutting speed is in accordance with an empirical formula. As long as the threshold is above the threshold, the cutting speed of the material is proportional to the laser power density, that is, increasing the power density can increase the cutting speed. The power density referred to here is related not only to the laser output power but also to the beam quality mode. In addition, the characteristics of the beam focusing system, that is, after focusing the spot size also has a great impact on laser cutting.

The cutting speed is inversely proportional to the density (specific gravity) and thickness of the material being cut. (Such as from high-order mode to low-order mode up to TEM00); reduce the focus spot size (in the range of 500 to 2 000 W) Such as plastic, plexiglass, etc.); cutting low-density materials (such as white pine, etc.); cutting thin materials.

In particular, for metal materials, the laser cutting speed can have a relative adjustment range while maintaining a satisfactory cutting quality when the other process variables remain constant. This adjustment range appears to be slightly smaller than that of the thicker width. Sometimes, the slow cutting speed will lead to the excretion of hot melt material surface, so that the surface is very rough.

2. The effect of focus position adjustment on cutting quality

Since the laser power density has a great influence on the cutting speed, the choice of lens focal length is an important problem. After focusing the laser beam, the spot size is proportional to the focal length of the lens. After the beam is focused by the short focal length lens, the spot size is very small and the power density at the focal point is very high, which is advantageous for cutting the material; but its disadvantage is that the depth of focus is very short, Small, generally more suitable for high-speed cutting thin materials. As the telephoto lens has a wide focal length, as long as there is sufficient power density, more suitable for cutting thick workpiece.

The relative position of the focus and the workpiece surface is particularly important to ensure the quality of the cutting after determining which lens to use. Due to the high power density at the focal point, in most cases, the focus position at the time of cutting is just at the surface of the workpiece, or slightly below the surface. Throughout the cutting process, ensuring that the relative position of the focus and the workpiece is constant is an important condition for obtaining a stable cutting quality. Sometimes, the lens work due to poor cooling and heat caused by changes in focus, which requires timely adjustment of the focus position.

When the focus is in a better position, the slot is smaller, more efficient, better cutting speed can get better cutting results.

In most applications, the beam focus is adjusted to just under the nozzle. Nozzle and the workpiece surface spacing is generally about 1.5mm.

3. Effect of auxiliary gas pressure on cutting quality

In general, material cutting requires the use of auxiliary gas, the problem is mainly related to the type and pressure of auxiliary gas. Typically, the auxiliary gas is coaxial with the laser beam to protect the lens from contamination and blow away the bottom slag of the cutting zone. For non-metallic materials and parts of metal materials, the use of compressed air or inert gas, the treatment of melting and evaporation materials, while inhibiting excessive cutting of the cutting area.

For most metal laser cutting is the use of active gas (as long as O2), the formation of hot metal and the formation of exothermic reaction, this part of the additional heat can increase the cutting speed of 1/3 ~ 1/2.

In the premise of ensuring the auxiliary gas, the gas pressure is a very important factor. When high-speed cutting of thin materials, the need for higher gas pressure to prevent the incision on the back of sticky slag (hot sticky slag to the workpiece will damage the trimming). When the material thickness increases or the cutting speed is slow, the gas pressure should be appropriately reduced. In order to prevent the plastic cutting and frosting, it is also cut with a lower gas pressure.

Laser cutting practice shows that when the auxiliary gas is oxygen, its purity has a significant effect on the cutting quality. A reduction in oxygen purity of 2% reduces the cutting speed by 50% and results in a significant deterioration in the quality of the incision.

4. Effect of laser output power on cutting quality

For the continuous wave output of the laser, the laser power size and mode will have an important impact on the cutting. In practice, often set the higher power to obtain a higher cutting speed, or to cut thick materials. However, the beam pattern (the distribution of beam energy in the cross section) is sometimes more important, and the pattern often changes slightly when the output power is increased. It is often found that a higher power density is obtained at a focal point that is less than a high power condition and a better cutting quality is obtained. During the full active life of the laser, the pattern is not consistent. The condition of the optical element, the fine change of the laser working mixture, and the fluctuation of the flow rate all affect the mode mechanism.

In summary, although the factors affecting the laser cutting is more complex, but the cutting speed, focal position, auxiliary gas pressure and laser power and mode structure is four very important variables. In the cutting process, if found that the quality of cutting significantly worse, we must first check the factors discussed above and timely control.

Brief Introduction to CO2 Laser Working Principle and Classification

The carbon dioxide laser was first used in 1964 with a wavelength of 10.6 μm. Because this is a very efficient laser, as a commercial model for its conversion efficiency of 10%, so carbon dioxide laser widely used in laser cutting, welding, drilling and surface treatment. As a commercial application of laser up to several kilowatts, which is currently the strongest material handling laser.

1.The operating principle

Carbon dioxide laser is a molecular laser. The main substance is carbon dioxide molecules. It can express a variety of energy state which depends on its vibration and rotation of the form may be. The mixed gas in the carbon dioxide is a plasma (plasma) formed by low-pressure gas (usually 30-50 torr) due to electron release. As in the Maxwell-Boltzmann distribution law, in the plasma, the molecules exhibit a variety of excited states. Some will exhibit a high energy state (00o1) which behaves as an asymmetrical swing state. When the collision with the hollow wall or natural distribution, this molecule will accidentally lose energy. This high-energy state will naturally descend to a symmetrical wobble (10o0) and radiate a photon (a 10.6μm light beam) that may propagate in any direction. Occasionally, a kind of photon that will travel down the cavity of the optical axis will also swing in the resonance mirror.

In general, carbon dioxide laser working material is composed of carbon dioxide, helium, nitrogen mixture. Nitrogen acts as a buffer gas as well as its molecules resonate to deliver energy to the carbon dioxide molecules. Because the level of relaxation is the bottleneck, the helium acts as a heat sink to deliver energy to the helium atoms.

2.The type of carbon dioxide laser

Waste heat rejection of the way the laser system design has a great impact. In principle, there are two possible ways. The first way is based on automatic processing of natural diffusion of hot air to the pipe wall, the operating principle is sealed and slow axial laser. The second is based on gas forced convection, its operating principle is fast axial laser. In general, there are five main types of carbon dioxide laser:

Sealed or no flow

Slow axial flow

Fast axial flow

Fast horizontal flow

Horizontal excited atmosphere (TEA)

Sealed or flowless carbon dioxide lasers are usually marked with a laser for beam deflection. Its discharge tube is completely sealed. The quality of this laser beam is very good. And in most cases the entire discharge tube can be replaced with old and new can be re-filling so easy to maintain. This eliminates the need for a separate gas supply system. Only need to do less in the laser head connection. So it is both compact and lightweight. But its energy output is low (usually less than 200 watts).

TEA carbon dioxide laser is usually used in the manufacture of protective cover. Can only operate in the pulse situation. Low air flow and high pressure. Its excitation voltage is about ten thousand volts. The distribution of the laser beam energy in the relatively large area is uniform. Its maximum energy can reach 1012 watts and its pulse width is very small. However, this type of laser is difficult to concentrate at a small point due to the multi-state operation.

Programming skill in smart soldering machine

Requirements for solder wires for soldering robots

Robots can be selected according to the needs of barrels or disc welding wire. In order to reduce the frequency of replacement of the wire, the robot should use barrels of wire, but the use of barrels of wire, wire feeding hose is very long, large resistance to the welding wire stiffness and other high quality requirements. When using less copper wire quality, the copper surface due to friction off the friction tube will result in reduced volume, high-speed wire feeding resistance increases, the wire can not be sent out smoothly, resulting in jitter, arc instability, affecting the welding Seam quality. Severe, there stuck phenomenon, so that the robot shut down, it is necessary to promptly clean up the wire tube.

Summary of programming skills

(1) Select a reasonable welding sequence. To reduce the welding deformation, welding torch walking path length to develop the welding sequence.

(2) welding gun space transition requires a shorter trajectory, smooth, safe.

(3) optimization of welding parameters. In order to obtain the best welding parameters, the production of test pieces for welding test and process assessment.

(4) a reasonable location of the positioner, torch attitude, relative position of welding torch. After the workpiece is fixed on the positioner, if the weld is not the ideal position and angle, it is required to adjust the positioner constantly during the programming so that the welding seam will reach the horizontal position one by one according to the welding sequence. At the same time, , Reasonably determine the location of welding torch relative to the joint, the angle and the wire out length. After determining the position of the workpiece, the position of the relative position of the torch through the programmer's eyes to observe, more difficult. This requires programmers to sum up accumulated experience.

(5) the timely insertion of clean gun program. After a certain length of welding program is prepared, the program should be inserted in time to prevent the welding spatter jamming the welding nozzle and the contact tip, to ensure the cleaning of the welding torch, to improve the life of the nozzle, to ensure reliable arc and reduce welding spatter.

(6) the preparation process is generally not one step, in the robot welding process to continuously test and modify the program, adjust the welding parameters and torch attitude, etc., will form a good program.
