  • The main advantages of laser marking machines for marking auto parts
    Jun 07, 2024 The main advantages of laser marking machines for marking auto parts
    The common auto parts marking methods on the market are: mold casting, electro-corrosion marking, stickers, screen printing, pneumatic marking and laser marking. Among them, although laser marking technology was born the latest, it has attracted widespread attention for its indelible marking since its birth. The main advantage of using laser for auto parts marking is that it is a fast, programmable, non-contact process with a long-lasting process that is usually not affected by the steps required in the production process or the harsh on-site environment it is subjected to. Of course, it also has disadvantages, such as the high initial cost of laser marking equipment and insufficient contrast of marking in some applications (such as marking plastic products). Laser, barcode and QR code are widely used in auto parts traceability. Barcode and QR code are popular technologies for product traceability in various forms today, and are fully applicable to all types of auto parts. Early auto parts marking mainly relied on marking serial numbers on products to meet traceability requirements. After the birth of barcodes, they were quickly applied to the identification of auto parts, but their small amount of information and poor fault tolerance prevented them from being fully popularized. This problem was not solved until the birth of QR code technology. A QR code is a 2D graphic similar to a chessboard that can hold a lot of information in a very small area. Since the 2D graphics of a QR code only require readout performance at a contrast ratio of 50% or even lower, the use of QR code graphics greatly increases the number of laser applications. The encoding of the QR code also has a built-in correction function, so the code can still be read even if part of the code is damaged for some reason. QR codes can also be decoded and encrypted in several different forms, and protection devices are placed in the data, making this type of marking more valuable for patented components. In addition to automatically generating barcodes, the marking software also supports QR code technologies such as DataMatrix, PDF417, QR Code, etc. Lasers can mark most materials used in automobiles with permanent, high-contrast marks. Laser marking machines can be used as stand-alone mass-production marking solutions for marking small workpieces, or they can be fully integrated into production lines. Flexible software control programs can customize any form of marking content. Lasers are becoming increasingly important in the automotive industry and are increasingly affecting our daily lives.

  • Classification and advantages of laser marking machines
    May 29, 2024 Classification and advantages of laser marking machines
    Laser marking machines use laser beams to mark permanent marks on the surfaces of various materials. The effect of marking is to expose the deep material through the evaporation of the surface material, thereby engraving exquisite patterns, trademarks and texts. In the Chinese laser industry, practitioners have made specific descriptions and classifications of it. After the enterprise customers state their requirements, they can recommend the selection of appropriate models according to the actual development situation. A. Classification of commonly used laser marking machines: 1. Fiber laser marking machine: The main technology is used to mark the required text, patterns, barcodes and other information graphics on plastic, electronic, metal, ceramic, tobacco and other material products. The fiber laser marking machine has the advantages of simple, fast and convenient operation, fast marking speed and clearness, which continuously optimizes the production management efficiency of enterprises. 2. UV laser marking machine: The industry used is the same as that of fiber laser marking machine, but the printed text, pattern, etc., when some fiber laser marking machines cannot engrave the required effect, the characteristics of UV laser marking machine are reflected, because UV laser marking machine belongs to the category of cold light, many products fiber laser marking machine cannot engrave satisfactory effect, UV laser marking machine can generally engrave. 3. Carbon dioxide laser marking machine: CO2 laser marking machine uses laser beam to mark the surface of various materials in various ways. Carve out patterns, trademarks, dates, LOGO or through text. At present, CO2 laser marking machine is mainly used in some Chinese wood, paper, etc. of enterprises. B. Advantages of laser marking machine: 1. Permanence: For example, the mark will not fade due to environmental factors (touch, acidic and reducing gases, high temperature, low temperature, etc.). 2. Anti-counterfeiting: The mark engraved by laser marking technology is not easy to copy and change, and has strong anti-counterfeiting to a certain extent. 3. Non-contact: Laser marking is processed by non-mechanical "light knife", which can print marks on any regular or irregular surface, and the workpiece will not generate internal stress after marking, ensuring the original precision of the workpiece. It does not corrode the working surface, there is no "tool" wear, no toxicity, and no pollution. 4. Wide applicability: Laser can be used as a processing method to process a variety of metals and non-metallic materials (aluminum, copper, iron, wood products, etc.). 5. High engraving accuracy: The laser marking machine engraves fine patterns on objects, with a minimum line width of 0.04mm. The marking is clear, durable and beautiful. Laser printing can meet the needs of printing a large amount of data on extremely small plastic parts. For example, it can print two-dimensional barcodes that require more...

  • Working principle of laser marking machine
    May 17, 2024 Working principle of laser marking machine
    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.

  • How to adjust the parameters of laser welding robot?
    May 08, 2024 How to adjust the parameters of laser welding robot?
    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. ...

  • Explore the optical principles in the PESLASER handheld welding head
    Dec 13, 2021 Explore the optical principles in the PESLASER handheld welding head
    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...
