The main function of mobile phone nuts is to connect plastic parts with metal parts, or to connect metal parts with metal parts for fastening purposes. Stainless steel nuts for mobile phones generally use methods such as rotary riveting and pressure riveting to connect the nuts to stamped parts or other workpieces of mobile phones.
However, the rotary riveting method is not economical, and the pressure riveting method is prone to deformation and other effects on other components. Laser welding machine has advantages such as high energy density, high welding efficiency, small thermal impact, and small deformation. Laser welding machine adopts non-contact welding method, which is not affected by the size and morphology of the workpiece, and can achieve long-distance fast welding. It is very suitable for nut welding of mobile phones.
The welding principle of the mobile phone nut and bolt laser welding machine is based on the welding technology of laser high thermal energy and concentrated fixed points. Laser deposition welding is used, and surface heat is transmitted and diffused internally. By controlling parameters such as the width, energy, peak function, and repetition frequency of the laser pulse, the workpiece is melted to form a specific molten pool and achieve the welding effect.
