Laser marking machine uses laser beam to permanently mark the surface of various materials. The effect of marking is to expose the deep material "engraving" traces through the evaporation of surface material or the chemical and physical changes of surface material caused by light energy, or to burn part of the material through light energy to show the pattern and text to be etched. There are two recognized working principles: 1. Hot processing: "Hot processing" has a laser beam with high energy density (it is a concentrated energy flow), which is irradiated on the surface of the processed material. The surface of the material absorbs the laser energy and produces a thermal excitation process in the irradiated area, so that the temperature of the surface (or coating) of the material rises, resulting in deformation, melting, ablation, evaporation and other phenomena. 2. Cold processing: "Cold processing" has (ultraviolet) photons with very high load energy, which can cut the chemical bonds in the raw materials (especially organic materials) or the surrounding medium, so that the raw materials are destroyed in a non-thermal process. This kind of cold processing has special significance in the laser marking process, because it is not thermal ablation, but cold peeling that cuts the chemical bonds without the side effect of "thermal damage", so it will not cause heating or thermal deformation to the inner layer and surrounding area of the processed surface. For example, in electronic manufacturing, excimer lasers are used to deposit chemical films on substrate materials and to create narrow grooves on semiconductor silicon wafers. Laser marking machine application industries: Widely used in integrated circuit chips, computer accessories, industrial bearings, watches, electronic and communication products, aerospace devices, various auto parts, home appliances, hardware tools, molds, wires and cables, food packaging, jewelry, tobacco, military affairs and many other fields for marking graphics and texts, as well as mass production line operations.

In order to meet the growing welding demand and the quality of welded joints, the welding industry urgently implements transformation and upgrading. Automatic welding robots have improved the level of automation and intelligence of welding. Enterprises use automatic welding robots to replace traditional welding. Before operating the welding robot, it is necessary to adjust the welding parameters according to the specifications of the weldment to help stabilize the welding quality. The welding parameters of the welding robot mainly include welding current, welding voltage, welding power source type, welding speed, etc. Setting the welding parameters properly can help the welding robot improve the welding efficiency while stabilizing the welding quality and clarify the production cycle of the product. When adjusting welding parameters, you need to pay attention to the following points: 1. Matching of welding current, voltage and welding wire. Welding current is an important welding parameter of the welding robot. The welding current is usually set together with the welding voltage. Before the welding robot enters mass production, debugging work needs to be carried out to set the welding current and voltage. In the case of short-circuit transition, the welding current increases, the welding voltage decreases, and the short-circuit current increases to a certain value, and thin welding wire can be used for welding; in the case of fine-grained transition, thick welding wire can be used for welding. When the welding current is low and the voltage is high, the six-axis welding robot is prone to welding spot spatter and workpiece deformation during the welding process. Only when the voltage is low, the welding process becomes relatively stable and can make the welds very good. Ground forming is conducive to companies using welding robots to weld thin plates. 2. Setting of welding speed. The welding speed of the welding robot needs to match the speed of the company's production line. During the welding process, if the speed is set too fast, welding defects will easily occur. If the speed is too slow, it will easily slow down the production cycle. Therefore, the welding speed needs to be set according to the production line. . 3. Welding direction. The automatic welding robot will weld according to the setting of the welding direction. There are two welding directions when setting up. One is the forward method, which means that the arc does not act directly on the workpiece, but pushes the molten pool away. The other is In the retreat method, the arc acts directly on the workpiece and avoids the molten pool. These two welding directions are set according to the actual situation. 4. Welding angle. The automatic welding robot will weld according to the setting of the welding direction. There are two welding directions when setting up. One is the forward method, which means that the arc does not act directly on the workpiece, but pushes the molten pool away. ...

A.Welding machine maintenance: 1.Clean the laser welding machine: The laser welding machine will produce dust, impurities, etc. during use, which will affect the stability of the machine output. Before cleaning, you need to cut off the power first and wait for the machine to cool down, then wipe the stained area and place it in a dry and clean environment after cleaning. 2.Check the cooling system: The cooling system is an important part of the laser welding machine. If the water is insufficient, it needs to be added to the appropriate water level. If the water quality becomes turbid, a clean water source must be replaced to keep the cooling system clear and at a suitable temperature. 3.Maintenance of parts: During long-term use of the laser welding machine, parts will be consumed and worn. If any problematic parts are found, they must be repaired or replaced in time to avoid affecting the welding quality. 4.Correctly operate the laser welding machine: The laser welding machine is a relatively advanced welding equipment with a complex structure. You need to pay attention to the sequence of starting up and shutting down, and check whether the indicator light lights up correctly. 5.Test the laser welding machine: Use some corner materials for test welding before welding, observe the operating status of the equipment and the welding quality, stop and investigate in time if there are any abnormalities, and contact the manufacturer to solve the problem. B.Welding gun maintenance: 1.Check the contact tip: The contact tip will be worn or stained with spatter during use, which will affect the formation of the weld. If it is damaged, replace it in time. 2.Pay attention to the temperature of the welding gun: The temperature of the welding gun increases after being used for a long time, especially in hot summer. It is best to place it in a ventilated place to carry out welding work. C.Chiller maintenance: 1.Place the chiller in a ventilated and cool place. It is recommended to use it below 40 degrees. When using a laser chiller, the machine room must be kept clean and well ventilated, and the condenser must be cleaned regularly to ensure that the unit can work normally. 2.The water should be changed regularly and the water tank should be cleaned regularly. The water should be changed regularly every 3 months. 3.The quality and temperature of the circulating water will affect the service life of the laser tube. It is recommended to use pure water and control the water temperature below 35 degrees Celsius. 4.When the unit fails and alarms to shut down, you should first press the alarm shutdown button and then check the cause of the fault. Remember not to force it to start operation before the fault is eliminated. 5.Regularly clean the condenser and dust filter of the chiller. 6.Unless there is an emergency during use, do not shut down the unit by cutting off the power supply; 7.In addition to daily maintenance, winter maintenance also needs to prevent freezin...

Handheld laser welding equipment is an epoch-making star product in the laser application market in recent years, and it has rapidly emerged as one of the growth points of the green laser industry. Since 2018, the annual compound growth of laser hand-held welding has exceeded 100%, and it is expected to reach 500 integrated manufacturers of various types of hand-held laser equipment in 2021, showing explosive growth. For handheld laser welding equipment, the welding head that connects to the use scene and outputs laser energy is an extremely important component. In the welding head, the optical part is a very important part. PESLASER handheld welding head The basic optical principle of the handheld welding head includes three parts: beam collimation, beam swing, and beam focus, as shown in the figure below. After the laser beam is emitted by the QBH, it becomes parallel light through the collimator, and then is reflected by the galvanometer to the focusing mirror, and finally focused on the surface of the workpiece. Beam swing In handheld welding, the purpose of beam swing is to improve the adaptability of the weld gap. Since the focused light spot is a small light spot, it is difficult to ensure that it walks along the weld track while holding it. On the other hand, it is also difficult to cover the weld with a large gap. By placing the beam into a straight line as wide as 3.0mm, it is convenient for the operator to align the laser and cover the weld. Its realization is that the vibrating lens deflects back and forth at a high speed under the drive of a motor, so as to achieve the purpose of changing the path of the laser beam. The basic principle is shown in the figure below: According to the basic law of reflection, the angle of reflection is equal to the angle of incidence. When the galvanometer is at the No. 1 angle, the light is reflected along the No. 1 path and focused to the No. 1 point; when the galvanometer is at the No. 2 angle, the light is reflected along the No. 2 path and is focused to the No. 2 point. If the galvanometer is deflected back and forth between the angles of 1, 2, and the focused light spot will move between the 1, 2 points. When the moving speed is fast enough, it can be regarded as a straight line. The length of this straight line is called It is the "swing width", and the deflection speed is called the "swing frequency". Beam focus What is reflected from the galvanometer is a beam of parallel light, which is condensed into a small spot after passing through the focusing lens, and finally incident on the surface of the workpiece. The function of the focusing lens is to gather the parallel light beams together to form a small light spot, thereby generating a super energy density. Protect the lens Hand-held welding will produce a certain amount of smoke and dust during the welding process, which may damage the focusing lens, so it is necessary to protect the lens to protect it. The protective lens is a consumable item...
