Abstract

The invention provides a method for manufacturing a terminal member and the terminal member. The method for manufacturing the terminal member includes the steps that a substrate is processed to form a preliminary structural member; a cylinder for generating a buckling structure is welded to the preliminary structural member in a friction stir welding mode; the welded cylinder is processed to generate the buckling structure; and a bearing part is matched with the buckling structure through screws and fixedly connected with the preliminary structural member in a hot melting adhesive dispensing mode to form the terminal member. According to the scheme, the processed substrate (the preliminary structural member) and the buckling structure (formed by processing the cylinder) are connected together in the friction stir welding mode, and then the bearing part is matched with the buckling structure through the screws and fixedly connected with the preliminary structural member in the hot melting adhesive dispensing mode to finally form the terminal member. The process is greatly simplified, the production efficiency, the material utilization rate and whole terminal strength are improved, and production cost and warping risks of the terminal member due to terminal dropping or distortion are reduced.

Description

technical field [0001] The invention relates to the technical field of terminal component production, in particular to a method for preparing a terminal component and the terminal component. Background technique [0002] In recent years, the application of mobile phones has become more and more extensive, and has gradually become the vane of consumer electronics products. Among them, the middle frame is the core structural part and appearance part of the mobile phone, which carries the main mechanical properties and appearance effects of a mobile phone. Therefore, the molding and processing technology of the middle frame largely determines the overall performance and appearance of the mobile phone. [0003] At present, the aluminum alloy middle frame of high-end mobile phones on the market mainly adopts two processes: one is made of aluminum alloy computer numerical control machine tool CNC + nano-injection molding, and the other is magnesium alloy die-casting + dispensing a...
