Laser welding machines are widely used in many industries, including sheet metal, machinery, automotive, mold, medical equipment and other industries. The entire welding process of the laser welding machine is composed of several parts, including the workbench panel and feed mechanism, which are fixed on the workbench panel. The clamping mechanism is fixed on the feeding mechanism. The feeding mechanism drives the clamping mechanism to move back and forth. The clamping mechanism includes a clamping device and a clamping mounting plate. The clamping device is provided with a positioning device. So how the machine system is composed and how the system works, let's check.
The laser welding machine system is generally composed of five parts:
The laser welding host machine
The cooling system
The laser welding automatic table or motion system
Fixture
Observation system
Working principle of laser welding machine
The laser welding machine host produces laser beams for welding, which is composed of main components such as power supply, laser generator, optical path part, control system, etc..
The cooling system provides cooling function for the laser generator, generally equipped with 1-5 horsepower circulation chiller (mainly used for square and round laser welding machine).
The laser beam moves according to the welding trajectory according to specific requirements, and realizes the automatic welding function of the laser welding machine. There are generally three types of motion control: workpiece movement, laser head fixation, laser head movement, workpiece fixation, or laser head and workpiece movement. The entire system has compiled a motion control program by means of numerical control programming. It controls the movement of the workbench according to the requirements. After a simplified programming system, it has the advantages of simple operation and fast mastering, without the need of professional technology or educational background. In the square and round laser table systems, such as: manipulator motion system, two-dimensional, three-dimensional table, four-axis linkage table, gantry welding table, cantilever table, etc., can achieve accurate welding motion control.
Generally speaking, in the laser welding process, the laser welding fixture is mainly used for fixing the welding workpiece, so that it can be repeatedly loaded and unloaded, and repeatedly positioned to facilitate automatic laser welding. Therefore, the fixture is a necessary equipment for laser welding production, especially in mass production. Whether the fixture design is in place will directly affect production efficiency and output. General laser welding machine has a large number of professional support designers, and specially designed laser welding clips are solutions for customers. And provide a 3D demonstration, so that customers can clearly understand the entire welding program.
The laser welding machine generally needs to be equipped with an observation system, which can perform real-time microscopic observation on the workpiece. When preparing the welding program, it is convenient to accurately locate and check the welding effect during the welding process. Generally equipped with CCD display system or microscope
When the pump light passes through the rare earth ions in the optical fiber, it will be absorbed by the rare earth ions. At this time, the electrons of the rare earth atoms that absorb the energy of the photon will be excited to a higher laser energy level, thereby inverting the number of ions. The number of counter ions will be transferred from the high energy level to the ground state in the form of radiation, and release energy to complete the stimulated radiation. The laser generated by the laser welding machine is output through the fiber, and cooperates with the supporting worktable to complete the corresponding welding. The laser welding machine is divided into pulse laser welding machine and continuous laser welding machine. Among them, the pulse laser welding machine can adjust the laser pulse single-point energy by setting the laser peak power, frequency and pulse width; the continuous laser welding machine can adjust the output laser power by setting the average laser power.
So that's all about the laser welding machine system. We also have CO2 laser marking machine, UV laser marking machine, click here now!
