How does the laser welding machine operate1 Laser welding machine has many applications in the field of industrial processing. How to avoid some potential safety hazards in the process of laser welding machining? Let's talk about the operating procedures of laser welding machine.1. Carefully read the product operation manual of the laser welding machine, and operate the laser welding machine in strict accordance with the operating procedures to ensure the safety of equipment and personnel.
2. In the process of laser welding machine, we also need to pay attention to keeping the environment and laser welding machine clean. We should often check whether the laser rod and optical elements are polluted.3. The shell of the laser welding machine needs to be connected with safety grounding. During operation, do not face the laser beam with your eyes, and do not let your body (such as hands) contact the laser beam, so as to avoid injury.4. If the laser welding machine needs to be overhauled, it must be powered off, and it must be confirmed that the charge on the energy storage capacitor has been discharged before it can be overhauled, so as to avoid electric shock accidents. In case of any abnormality during operation, power off (press emergency stop and air switch) for inspection.
5. The circulating water in the laser welding machine must be kept clean, otherwise it will affect the output size of the laser. The user can determine the cycle of changing the cooling water according to the startup time, water quality and other conditions. Generally speaking, the water change cycle in summer is shorter than that in winter.2 During the operation of the laser welding machine, there are certain requirements for the working environment, and the ventilation device is also very important for the laser welding machine, because the ventilation device directly affects the laser processing effect. Here is an explanation of the ventilation device of the laser welding machine:First: local exhaust
In the process of laser welding machine processing, there will be an exhaust device, so the exhaust device is also a kind of ventilation device. It is composed of exhaust fan, which is used to alleviate the local exhaust, which can improve the processing effect and indirectly protect the environment.The second type: comprehensive ventilationThe so-called comprehensive ventilation means to ventilate the environment in the working room of the laser welding machine, dilute the air inside, and purify the air inside to achieve a good working environment. This way can indirectly improve the processing effect. The above two schemes are commonly used in ventilation devices at present. Mastering the methods can ensure the convenience of operators, improve the processing effect and make the work of laser welding machine more satisfactory.
These two schemes are commonly used in ventilation devices at present. Mastering good methods can ensure the convenience of operators, improve the welding effect and make the work of laser welding machine more satisfactory.Selection of laser welding machineNow there are countless laser welding machines on the market. Laser welding machines can be widely used in all walks of life in today's social environment. Now many colleges and universities will also buy teaching laser welding, which is not only used for teaching but also for scientific research. If you want to buy such a device, So the businesses in the market are basically flocking. It can be said that there are many manufacturers of laser welding machines in the market. In the face of so many manufacturers, how can we choose a good equipment.
1. Confirm whether the product is suitable for welding with laser welding machineWhen selecting laser welding, we must first confirm that our products are suitable for laser welding. Now many laser welding manufacturers basically provide free proofing, so we can ask the other party to proofing before purchasing, so we can see whether laser welding can meet our requirements.2. The power of laser welding machine shall be considered
Laser is the core of laser equipment. The higher its power is, the higher its price will be. At the same time, because of the high power, the higher the requirements for the equipped laser rod and cooling system; Generally, the deeper the welding depth is required, the greater the power of the corresponding laser welding machine.3. Make reasonable choices according to budget and hobbiesSome people are more loyal to foreign brands, and the price will naturally be higher. Since there is no tariff problem, the price of domestic laser welding machine will be relatively low. Now the domestic laser technology has reached the international standard, and the after-sales problems will be handled more timely and conveniently, so it will be more guaranteed. We can choose according to our budget and hobbies.
Classification of laser welding machinesLaser welding machine is also often called laser welding machine, energy negative feedback laser welding machine, laser welding machine, laser welding machine, laser cold welding machine, laser argon welding machine, laser welding equipment, etc.1. According to its working mode, it can be divided into: laser mold welding machine: it is mainly used for mold repair in mold manufacturing and molding industries such as mobile phones, digital products, automobiles and motorcycles, as well as manual welding.
Automatic laser welding machine: it is suitable for automatic welding of straight line and circumference of metal workpieces. It is commonly used in mobile phone battery, jewelry, electronic components, sensors, clocks and watches, precision machinery, communication, handicrafts and other industries. Resistance laser welding machine: it is more suitable for welding two positions at the same time, such as resistance, capacitance and other electrodes. Laser spot welding machine: it is mainly designed for some irregular objects such as gold and silver jewelry, micro and small parts. It can be used for repairing holes in gold and silver jewelry, electronic components, spot welding sand holes, welding inserts, etc.
Optical fiber transmission laser welding machine: better beam quality, finer spot, stronger energy, more stable output and higher welding accuracy. It is mainly applicable to the welding of buttons, battery lugs and other products and materials with small and high precision requirements.. Sensor welding machine: it is specially used for sealing welding of various underwater sensors, temperature sensors and special sensors. Fiber laser continuous welding machine: fiber laser continuous welding machine is a machine that realizes welding through a continuous light emitted by fiber laser. The light output mode is continuous. Because of its continuity, it has stronger energy and greater heat, which can instantly melt the product welding point and realize welding. It is mainly used in medical treatment, mobile phone, battery, electronics, hardware, instrument, optical communication, aluminum and other industries.
Galvanometer laser welding machine: compared with the traditional automatic welding machine, galvanometer welding controls the direction of laser through galvanometer to form round, square and other patterns. So what moves is the laser, not the previous workbench or fixture. So it's faster and more accurate. It greatly saves time cost and labor cost. Mainly used in: toys, mobile phones, electronic products, automobiles and other industries.2. According to the laser, it can be divided into: YAG laser welding machine, semiconductor laser welding machine, fiber laser welding, etc.Characteristics of laser welding machine
Laser processing is to irradiate the surface of the workpiece with the laser beam, and use the high energy of the laser to operate, melt materials and change the surface properties of the object. Because laser has the characteristics of high brightness, high directivity, high monochromaticity and high coherence, it brings the following rare characteristics to laser processing: because it is processing without knowledge, there is no necessary impact on the workpiece, so there is no mechanical deformation; there is no "tool" wear and no "cutting force" acting on the workpiece during laser processing;
during laser processing, the laser beam has high energy density, fast processing speed and local processing, which has no or minimal impact on non laser sunlight parts. Therefore, the heat affected zone is small, the thermal deformation of the workpiece is small, and the previous machining is greater than; because the laser beam is easier to guide, discuss and construct direction conversion, it is not easy to correspond with the NC system and process simple workpieces, so it is an extremely flexible processing method; high production efficiency, stable and reliable processing quality, good economic and social benefits, and advantages of laser processing
With the rapid development of China's laser welding industry in recent years, we have been influenced by laser welding machines. Laser automatic welding machine welding technology is a comprehensive technology integrating laser technology, welding technology, automation technology, material technology, mechanical manufacturing technology and product design. As an advanced manufacturing equipment, in today's highly automated, laser automatic welding has begun to integrate into various industries.
Different from the traditional welding equipment, the closed-loop control laser welding machine of Shenzhen Zichen laser does not need to use electrodes, and there is no concern of electrode pollution or damage. Because it is not a contact welding process, the loss and deformation of machines and tools can be minimized. In addition, the energy characteristics of the laser beam of the closed-loop control laser welding machine are high, mainly including the wavelength of the laser beam and the power and power density of the beam. In the production of each laser welding machine, the quality requirements are more stringent, so the quality of this laser welding machine will directly affect the stability of the laser beam?
Laser welding machine plays a major role in welding is the laser power density value. This is because there is a critical power density threshold for different materials. Only when the power density value of the laser beam focus exceeds this threshold, can small holes be formed and deep penetration welding be obtained. This is for wavelength 10.6 M CO2 laser beam is of great significance. Because metal materials strongly reflect laser beams of this wavelength.
When the laser beam is the basic mode, the maximum weld depth and depth width ratio can be obtained. The higher the order of the beam mode, the more divergent the energy distribution of the laser beam and the worse the welding quality. The influence of laser beam with different beam focusing characteristic parameter value K on laser welding quality. The larger the beam K value, the worse the quality and the smaller the depth width ratio of weld. The power density of forming small holes in materials is not only related to the average power density, but mainly depends on the maximum power density, which is closely related to the cross-sectional energy distribution.
The relationship between the quality of laser welding equipment and the beam mode characteristics. The beam mode characteristics include the beam quality, beam mode and cross-sectional energy distribution of laser beam. The beam mode determines the energy distribution of the focus, which has an important impact on laser processing. The quality of laser welding machine affects the beam stability. Let's share it here. The laser welding machine has different cross-sectional energy distribution for the focus with certain power and the same radius. Although the average power density is the same, the maximum power density is not the same.fqj
LED lamp is an electroluminescent semiconductor material chip, which can directly convert electricity into light. Use silver glue or white glue to cure it on the support, then connect the chip and circuit board with silver wire or gold wire, seal it with epoxy resin around to protect the internal core wire, and finally install the shell, so the seismic performance of LED lamp is good.
The structure of existing LED lamps is usually that the substrate loaded with LED semiconductor chip is vertically contained in the lamp tube. The semiconductor chip is composed of two parts. One part is p-type semiconductor, in which holes are dominant, and the other end is n-type semiconductor, mainly electrons. But when the two semiconductors are connected, a p-n junction is formed between them. When the current acts on the chip through the wire, the electrons will be pushed to the p region, where the electrons and holes compound, and then emit energy in the form of photons. This is the principle of LED light emission. The wavelength of light, that is, the color of light, is determined by the material forming the p-n junction.
characteristic:1. Energy saving: the energy consumption of white LED is only 1 / 10 of that of incandescent lamp and 1 / 4 of that of energy-saving lamp.2. Longevity: the service life can reach more than 100000 hours, which can be described as "once and for all" for ordinary family lighting.
3. It can work at high speed: if the energy-saving lamp is started or turned off frequently, the filament will turn black and break down quickly, so it is safer.4. Solid state package, belonging to the type of cold light source. Therefore, it is easy to transport and install, and can be installed in any micro and closed equipment, not afraid of vibration.5. LED technology is progressing with each passing day. Its luminous efficiency is making an amazing breakthrough, and the price is also decreasing. An era of white LED entering the family is coming rapidly.
6. Environmental protection, no harmful substances of mercury. The assembly parts of LED bulbs can be easily disassembled and assembled. They can be recycled by others without being recycled by the manufacturer.Solder manufacturing process of LED lamps:
Because the semiconductor chip main control circuit board in the LED lamp is flake, and the annular base strip is circular, it is difficult to locate when welding the main control circuit board and the annular base strip, and there is no corresponding automatic welding equipment. At present, it is manual welding, the labor efficiency is low, and the work efficiency cannot be improved, Even if some special automatic welding equipment can complete solder treatment, the equipment production cost is very high. Therefore, Shenzhen Zichen laser equipment Co., Ltd. has improved the welding process of this product to enable it to realize the purpose of automatic welding after manual loading.
The laser automatic soldering machine for LED light plate includes a laser automatic soldering system, a 4-station rotating workbench, and several fixed fixtures for placing the LED light plate to be soldered. The welding process has the functions of CCD intelligent positioning, digital temperature control, pre welding tin spot welding and post welding detection. Nowadays, the laser soldering machine produced by Zichen is widely used in the automatic welding of LED lamp industry.fqj
