Automatic optical fiber cutting machine with follow-up cutting system on cutting

Taiwan group automatic fiber cutting machine vaporization cutting: When the laser power density focused on the surface of the material is very high, the temperature of the material surface rises extremely fast compared with the heat conduction, and it directly reaches the vaporization temperature without melting. Oxygen-free melting and cutting of materials for the group of automatic fiber optic cutting machines, if the auxiliary gas blown is an inert gas, the melted material will not come into contact with oxygen in the air, and no chemical reaction will occur. It is called anaerobic melting cutting. Therefore, under the same conditions, the laser energy required for oxygen-free melting and cutting will be higher than that of oxygen-assisted melting and cutting. Generally speaking, the higher the speed of oxygen flow, the more intense the exothermic reaction of metal material oxidation. The more thoroughly the generated slag is discharged by the high-speed oxygen flow, a higher cutting speed can be obtained. However, if the oxygen flow rate is too high, the air flow will take away too much heat energy, which will cause the molten metal to cool down and slow down the oxidation reaction rate of the metal. , Will produce the phenomenon of impenetrable. Oxygen-assisted melting and cutting of metal materials in a group of automatic fiber cutting machines, if the auxiliary gas blown is oxygen or an oxygen-containing mixed gas, the metal material heated by the laser will produce an oxidative exothermic reaction, which will generate an exothermic reaction outside of the laser energy. Another heat source-the heat energy produced by the chemical reaction of metals, and the two heat energy together complete the melting and cutting of the material, which is called oxygen-assisted melting and cutting. Laser scribing: Laser scribing mainly refers to scribing silicon wafers. Ceramic substrates, diamond films, solar cells, etc. are all controlled fracture cutting. Controlled fracture cutting For brittle materials that are easily damaged by heat, high-speed and controllable cutting is performed by laser beam heating, which is called controlled fracture cutting.

The main content of this cutting process of the Taiwan-group automatic fiber cutting machine is: the laser beam heats a small area of u200bu200bbrittle material, causing a large thermal gradient and severe mechanical deformation in this area , Causing the material to form cracks. As long as a uniform heating gradient is maintained, the laser beam can guide cracks in any desired direction. The characteristics of the workpiece and the wavelength of the laser have a great influence on the cutting effect: because they directly affect the absorption rate of the material to the laser energy. Automatic fiber cutting machine can be divided into three types: YAG lamp pump cutting machine, side pump cutting machine and fiber cutting machine. They are collectively referred to as YAG pulse group automatic fiber cutting machine. YAG means alumina synthetic spar used to generate laser beams. The wavelength of the generated laser light is 1064μm, which can be stimulated and absorbed by many metal materials. At this stage, the main production line is YAG lamp pump cutting machine. From the power point of view, we now have two types of lasers, 500W and 650W. The laser principle and cutting principle of pulse laser power supply YAG laser The xenon lamp converts the electric power into light under the action of the DC high voltage of the pulse laser power supply, and focuses it on the YAG laser rod through the condenser cavity to produce the initial radiation light, and then the output mirror The optical resonance cavity composed of a mirror and a total mirror is stimulated to radiate, and finally the laser is output. The generated laser light is amplified by the beam expander, and then becomes vertical light downward through the 45-degree reflector. Finally, it is focused by the focusing lens and then passed through the cutting nozzle. Finally, it becomes a laser beam that can be used for cutting, and auxiliary gas is required for cutting. (Oxygen, nitrogen, argon, air compressors, refrigeration dryers, oil-water separators, etc.) cooler chillers (refrigeration rate 18KW) part of the machine tool table with a follow-up exhaust device can solve the problem of cutting The optional rotating device for dust problem equipment can cut pipes with a diameter of 20-200. Offline motion control card, equipped with intelligent typesetting software, and with a follow-up cutting system on cutting.
