Description

A laser welding machine for mobile phone parts processing

technical field

The invention relates to the technical field of mobile phone processing, in particular to a laser welding machine used for processing mobile phone parts.

Background technique

The middle plate of the mobile phone is made of aluminum alloy outer frame and aluminum alloy middle plate for welding. Laser welding uses laser as a high-energy density light source. It is characterized by heating block and instantaneous solidification, and the aspect ratio is as high as 12:1. Therefore, laser welding can penetrate aluminum alloy doors and windows without thermal influence on the surface. However, due to the high reflectivity and good thermal conductivity of the aluminum alloy itself, as well as the shielding effect of the plasma, some defects will inevitably occur during welding. The two most important defects are pores and thermal cracks. One of the main defects of laser welding of aluminum alloys is the porosity problem. After testing, the generation of pores is mainly affected by the surface state of the material, the type of shielding gas, the flow rate and protection method, the welding energy and the shape of the weld and other factors. ) The generation of pores can be minimized during welding, and the annealing process after welding can effectively reduce the generation of cracks. Most of the existing technologies do not use gas protection during welding and annealing after welding, so there will be many pores and Hot cracks seriously affect product quality.

The Chinese invention patent with publication number CN106735899A discloses an automatic spot welding machine for welding the reeds of the reed carrier tape on the back shell of the mobile phone. The automatic spot welding machine includes a worktable, a material distribution mechanism, a conveying mechanism, a rotating mechanism, and laser welding machine; the conveying mechanism includes a support frame, a conveying track, and a suction device; a first conveying cylinder is arranged on the conveying track, and the first conveying cylinder pushes the suction device to slide laterally on the conveying track; A second conveying cylinder and a suction part are provided; the suction part is provided with a suction nozzle for absorbing the reed. The above-mentioned automatic spot welding machine is equipped with a carding track through the material distribution mechanism, and the reed carrier tape is carded, and then the reed is sucked to the back shell of the mobile phone through the conveying track, and then the reed is pressed by the reed pressing head, so that the reed is pressed. For laser welding machine welding, the whole process is controlled by the control system to realize automatic production. The whole equipment can be operated by one person, which greatly reduces the labor intensity of employees. Although the equipment improves the reed welding efficiency, it fails to solve the phenomenon of hot cracks and blowholes that may be caused by welding; as well as the inspection of products after welding and the classification of unqualified products.
