Mobile phone middle frame machining technology

Abstract

The invention discloses a mobile phone middle frame machining technology. The mobile phone middle frame machining technology comprises the following steps that: a to-be-machined mobile phone middle frame is provided and comprises a frame and a middle plate; a specular face, a TP face, an inner side face and a face screen supporting step face are machined on the frame; the frame is positioned, theTP face serves as the positioning supporting face, and excess shape leftover materials of the frame are milled off; the outer peripheral face of the frame is machined through first-time anodizing, sothat the outer peripheral face of the frame is colored; and the outer peripheral face is machined through second-time anodizing, so that the specular face, the TP face, the inner side face and the face screen supporting step face are colored. According to the mobile phone middle frame machining technology, the specular face, the TP face, the inner side face and the face screen supporting step faceare machined on the frame before the shape of the frame is milled, and thus the TP face can serve as the supporting face when the shape of the frame is milled; the TP face is flat, the excess leftover materials of the frame are not removed, the strength is high, thus the frame is not prone to deformation when the excess shape leftover materials are milled off by a milling machine, and the sizes of the specular face, the TP face, the inner side face and the face screen supporting step face are ensured.

Description

technical field [0001] The invention relates to the field of mobile phones, in particular to a process for processing a middle frame of a mobile phone. Background technique [0002] Mobile phones have now become an indispensable communication tool for people. People have higher and higher requirements for mobile phones. They are not just electronic devices for communication purposes, but integrated functions such as music, video, photography, and Internet access. Multimedia phone. With the continuous development of the mobile phone industry, the performance of mobile phones is becoming more and more powerful, especially the resolution and size of processors and screens are constantly improving. [0003] The middle frame of the mobile phone is an important part of the mobile phone, and the middle frame of the mobile phone includes a square frame 10 and a middle plate 20 installed in the frame 10 . Please also refer to figure 1 with figure 2 , figure 1 It is a structural...

Problems solved by technology

However, the processing technology is to first remove the excess shape edge material of the outer frame, and then clamp the middle frame of the mobile phone on the CNC lathe to CNC process the high-gloss surface 12, the TP surface 13, the inner surface 14 and the screen support step surface 15, The removal of the outer edge material will make the strength of the frame 10 lower, and the frame 10 with low strength is easily deformed when the high-gloss surface 12, TP surface 13, inner surface 14 and surface screen support step surface 15 are processed by CNC, so it cannot be guaranteed. The dimensions of the high-gloss surface 12, TP surface 13, inner surface 14, and screen support step surface 15 cannot guarantee that the distance from the screen support step surface 15 to the middle plate 20 is within the allowable tolerance range; in addition, CNC machining When the high-gloss surface 12, TP surface 13, inner surface 14 and face screen support step surface 15 are positioned through the middle plate 20, due to the unevenness of the surface of the middle plate 20, the support positions of the middle plate 20 on the fixture are not on the same plane On the other hand, there will be large dimensional errors in the processed high-gloss surface 12, TP surface 13, inner surface 14 and screen support step surface 15
