The main function of mobile phone nut is to connect plastic parts with metal parts, or to connect metal parts with metal parts to play a fastening role. The stainless steel nut of mobile phone is generally connected to the mobile phone stamping parts or other workpieces by means of rotary riveting and pressing riveting. But the rotary riveting method is very economical, the pressure riveting method is easy to produce the deformation and so on to other parts, and the laser welding machine has the advantages of high energy density, high welding efficiency, small heat effect and small deformation, and adopts the non-contact welding method, which is not affected by the size and morphology of the workpiece. It can realize long-distance and fast welding, which is very suitable for the nut welding of mobile phone.
The welding principle of mobile phone nut stud laser welding machine is to use laser high heat energy and concentrated fixed point welding technology, using laser deposition welding, surface heat is transmitted to the inside, by controlling the width and energy of laser pulse. Peak function and repetition rate make the workpiece melt and form a specific pool to achieve welding effect.
The stainless steel metal laser welding machine of Jiaxin laser adopts the method of no contact welding, the weld seam is flat and beautiful, the heat affected area is small, it will not cause deformation around the material, the welding speed is fast, and it is easy to realize automation.
Jiaxin laser warm reminder to use metal laser cutting machine should pay attention to safety matters:
1. comply with general cutting machine safety operation rules. Start the laser strictly according to the laser start program, dimming, test machine.
2. operators must be trained, familiar with cutting software, equipment structure, performance, and master the relevant knowledge of operating system.
3. wear labor protective equipment according to regulations, must wear protective glasses near the laser beam.
4. do not process a material before it is clear whether it can be irradiated or cut by a laser to avoid the potential danger of smoke and steam.
5. the equipment starts, the operator shall not leave the post or trust the person to be in charge, if it is necessary to leave, stop or cut off the power switch.
6. keep the fire extinguisher within reach; turn off the laser or light switch when not processed; do not place paper, cloth or other flammable materials near the unprotected laser beam.
7. abnormal in the processing process, should immediately stop, timely troubleshooting or report to the supervisor.
8. keep the laser, laser head, bed and surrounding site clean, orderly and free of oil pollution, workpieces, plates and scrap are stacked according to regulations.
