Laser welding machine application on the metal back shell frame of Apple mobile phone

The iPhone is the smart phone developed by Apple Inc. of the United States. It has won the favor of consumers because of its novel design and fast running speed system. With the rapid development of technology, and the demand of consumer for mobile phone is also increasing, and the requirements for welding various parts in mobile phone are also becoming higher and higher.

The original middle frame backplane material of the Apple mobile phone is welded by aluminum alloy frame and copper backplate material. The welding of the copper-aluminum alloy material has high requirements on the Laser welding equipment, and the manufacturing cost of processing is much higher, so many manufacturer change the backplane material to stainless steel. This makes the welding less difficult, and there are less limitations on the equipment requirements. The traditional welding process is increasingly unable to meet the requirements, the labor cost and subsequent processing cost are too high, so many manufacturers are looking for a welding method which can exceed the current welding quality and save the cost of labor and subsequent processing.

The laser welding equipment can achieve the effect of welding and fixing the stainless steel backplate and the aluminum alloy middle frame of the mobile phone.

The Laser welding machine uses high-energy laser pulse to locally heat the material in a small area. The energy of the laser diffuses into the material through heat conduction, and the material is melted to form a specific molten pool. The laser welding equipment can implement flexible access non-contact welding on the parts which are difficult to reach, this has greater flexibility. Compared with traditional spot welding and arc welding, laser welding has many advantages such as little thermal deformation, high efficiency, and good precision. However, its price currently is relatively expensive and the market penetration rate is low.

The fiber laser welding machine developed by Shenzhen Sunlaser is a new type of welding method. It is mainly used for the welding of thin-walled materials and precision parts. The weld seams are smooth and beautiful, no need further treatment after welding or only simple treatment is needed.
